Full Text SRIAN EMPOTOME
SYRIAN BMPOTOMB is the name given to the new invention, which incorporates unique features of scanning/imaging coupled with facilities for expeditious performance of neuro-surgical procedures embodied as a single unit. This invention is a very unique and novel idea in the field of neurosurgery.
SRIAN EMPOTOMB has a number of newer and useful features, which were hitherto not available in the existing craniotomes. This Empotome is not only an improvement of the existing craniotomes, but also possesses additional novel structures, expeditiously facilitating neuro-surgical procedures. The existing craniotomes, available at present, which are used in neuro¬surgical operations, are able to drill only a single burr-hole [making hole in the skull during opening of a skull J at a time and there is no facility to visualize the dura Afum - the outermost layer of the Brmu]
during drilling in order to prevent injury to the dural structures in the brain.
SRIAN EMPOTOMB on the other hand, improvises on this feature. The improvement incorporated in the "Empotome" is that, multiple burr-holes can be drilled on the skull, simultaneously, thus minimizing the time utilised. The dural il\jViry is also prevented by incorporating a endoscopic lens system with a light source in the burr itself, so that drilling may be stopped, as soon as the dura is vizualised or encountered. This is possible, by connecting the burr with a computer assisted system, which displays the surgical procedure on-line, on a video monitor / screen.

"SRIAN BBIPOTOMB" further, has the facility to perform intra¬operative neurosurgical imaging of the cranio-spinal axis, utilising the CT and MRI facilities, which have been incorporated in the form of a 'cranial helmet' for visualizing the brain and a 'retractable spinal extension of the helmet' for visualizing the whole spinal cord.
This form of imaging, utilizing CT Scan and MRI simultaneously in the same machine, at the same time, with facilities for super-imposition of both the CT and MRI images, is not only a new’ concept, but also, a very compact version of the existing intra-operative CT and MRI apparatus/es, which are hitherto available as separate units.
The existing CT and MRI apparatus/es are very huge, {as huge as a large room} and a patient has to be shifted from the operating table, to the MRI or CT table [ also known as gantry ], in order to get an image of the brain or the spinal cord, as the circumstances may demand. Moreover the CT and MRI images cannot be obtained simultaneously from the same machine and also cannot be super imposed. This handicap has been removed in the Empotome.
'SRIAN BMPOTOMB', has obliviated this shifting of the patient from the operating table, to the CT or MRI gantry, by incorporating the features of the CT and MRI on a very compact gadget, which is in the form of a helmet and a spinal extension, as stated earlier. The compactness of these gadgets viz., the helmet and the spinal extension, is due to the CT / MRI plates

which captures the image of the brain or the spinal cord and transmits it through the electronic connections, on to the screen, ‘vhich is a simultaneous activity and hence does not require the shifting of the patient, wrhich itself is a new concept, not available at present.
SRIAN BMPOTOMB, hence reduces the operative time and at the same time, performs the surgical procedures, expeditiously , without damaging the brain. The 'Empotome' also provides facilities for operational procedures of the brain and the spinal cord, without disturbing the patient from the operating table, hence facilitating intra-operative super-imposed CT and/or MRl imaging w’hich minimizes the trauma during shifting of the patient. These features provide an edge to the newly invented "Empotome" over the other existing craniotomes.
SRZAif BBSPOTOMB is, thus, the name given to the apparatus luhich implies :
CT Scanner & Magnetic Resonance Imaging Attachments in Neuro Surgical
apparatus alongwtth Endoscopic Burrs Ss a Multi Purpose Cranio TOMES.
Empotome, implies "Empo* + "tome", where "empo" refers to an abbreviated and mnemonic form of the letters *m' and 'p', in
the word 'multipurpose', and "tome" - aOo medkaCfy urmetC otomy-
suggesting 'cutting' or 'opening' during surgical procedures. Therefore, ISRIAN EMPOTOME" is a multi purpose apparatus comprising facilities for pre and/or intra-operative imaging alongwith features to facilitate early and expeditious surgery for opening of the skull and operating upon the brain.

THE MOST REVOLUTIONARY FEATURES OP THIS SRIAN EMPOTOMEARE :
The SRIAN BMPOTOMB can be used in the pre-operative period [Before surgery], per-operative period [during surgery] and in the post¬operative period [after surgery] for imaging studies. The combined facilities of imaging and performance of craniotomies, are exclusive to this new invention viz., 'SRIAN BMPOTOMB', both of which are not available, in the same apparatus, in any of the available craniotomes, being presently used to perform brain surgeries, till date. Hence, the existing craniotomes ceut only be used to perform neurosurgical operations tma cannot be used for imaging studies. This handicap has been removed by this new’ invention, 'SRIAN BMPOTOME', apart from possessing new features, which makes it a novel invention.
The imaging facilities alluded above include. Computed Tomography Scan [CTscan] 8B Magnetic Resonance Imaging Scan [M(1(/ scan] of the cranium and also the imaging of the spinal axis, through which an on-line image of the brain and the spinal cord can be visualised, not only before or after cranio-spinal procedures, but also during the performance of cranio-spinal procedures on-table.
This procedure of a combination of imaging and surgery, is extremely useful to assess the extent of surgery, the completeness of the surgery being performed and the requirement for future course of action during the process of surgery and also pre-emptive remedial measures that are to be taken to prevent injuries to the vital structures of the brain viz., the motor-cortex, the sensory-cortex, the speech area, the

olfactory, auditory and visual centres, the limbic system, the ventricles, the supra-cranial and infra-cranial vascular structures, the brain stem which includes the mid-brain, pons and medulla, the cranial nerves, the dural-venous sinuses, the cerebellum, the spinal cord including the cervical spine, dorsal spine and the lumbo-sacral spine and also the spinal nerves and the coverings of the brain and spinal cord.
Recognizing the importance of time and the need for a quick and expeditious craniotomy, w’hich are very important and vital factors in neuro-surgery, essential to prevent infection, blood loss, trauma secondary to retraction, cerebral edema etc., the 'SRIAN BMPOTOUS' embodies all the features of performing multiple burr-holes and imaging at that point of time, with precision and deftness, combined in a single apparatus.
The intra-operative imaging, facilitates the assessment of the completeness of resection of a particular tumor, the amount of residual tumor, the adjacent vital structures which have to be avoided during surgery, the surrounding and adjacent vascular structures which need to be avoided for preventing excessive hemorrhage etc. This prevents a second or subsequent operation, which minimises the risk of infection and trauma to the brain.
Additional important feature of this "SRIAN E’POTOMB" is that there is no necessity for the patient to be shifted out of the theatre for performing the MRI or CT scan. The image can be seen, as and when the operation is being performed.

This imaging facility in the " SRIAN EMPOTOME" is highly compact which does not occupy the space of more than the size of a helmet, which can not only be used separately as an imaging machine, but can also be combined with a craniotome. The brain and the spinal cord can be im’ed simultaneously. This combined feature is not available in any of the existing intra-operative machines. This " SRIAN EMPOTOME" does not require additional space, as stated earlier, and the imaging structures are detachable, which facilitates easy maneuvering.
1SRIAN EMPOTOME" has facilities for holding an endoscope, an intra¬operative sonar and a digital camera fis slots to place retractors. Besides being able to be operated upon, utilizing only electrical connections, it can also be connected to a computer for complete automation and three dimensional [ 3D ] visualisation.
As alluded earlier, it not only works on electricity but also has additional connections to the UPS and a battery source. The working is based both on pneumatic & hydraulic principles.
This new instrument can easily be mounted on any state of the art OT-Table 85 has all the facilities for performing cervical traction and for procedures on the neck, both before surgery and also while performing surgery, through a rotatable and adjustable neck-stand.

METHOD OF PERFORMING THE PROCEDURE UTILIZING THE INVENTION VIZ.. "SRIAN EMPOTOME"
"SRlAN EMPOTOME" is an instrument used in Neuro-surgical imaging
and operations.
Initially, a patient who requires imaging / neuro-surgical operation is
brought into the Operation Theatre [ OT ].
The patient is made to he down on the OT table.
The "SRIAN EMPOTOiyiE" consisting of the Head Ring and the
Neck Ring, is inserted from above downwards over the head of the
patient.
The Head ring mth the upper and the low’er case is adjusted,
according to the size of the head of the patient, using the slider
available in the "Srian Empotome".
The head ring is now fixed to the head of the patient by utilizing the
head ring fixator, after giving local anesthesia at the points where the
adjustable screw’ of the head-ring fixator penetrates into the skin of the
skull of the patient.
The adjustable screw’ provided in the fixator is moved either forwards /
Jt?i’Jt>vards, so that the head-ring is anchored tightly, allow’ing no
Mjovement of the head of the patient.
The Neck ring w’ill now lie over the shoulders of the patient.
The distance between the head ring and neck ring is adjusted
according to the need of the patient by the four verticzd rods.
The patient is now’ made to Ue on the Operation Table either in a
supine position [Lying on one's 6ac’ so tRat the face is turned towards the roof]

or in the prone position [Cying on one's stomacfi or addbmen, so tfiat the face is
turned towards the floor] depending upon the surgical needs.
The neck ring is now attached to the neck stand jind the height of the
table and the patient is accordingly adjusted.
After this rigid immobilization of the head emd neck of the patient,
the 'helmet' w’ith the 'retractable spinal extension' is anchored on to
the head ring.
The 'retractable spinal extension' is adjusted in such a w’ay over the
OT table, so that there is no inconvenience caused when the patient Ues
either in the supine or prone position.
The CT and MRl plates are now fixed in betw’een the head and neck
ring and slided along the vertical grooved slots available in the
vertical rods.
This apparatus is then connected to the AC/ DC / Battery / UPS
source as the case may be.
The apparatus is now’ connected to the computer and then on to a
monitor screen in the OT, so that the images are seen both
instantaneously and as an online image.
It now’ requires to assess whether the patient needs
(a) only imaging or
(b) imaging and surgery
(a) In case, the patient requires only CT / MRl imaging, without any immediate surgical intervention :
> the machine is turned on,
> the CT and/or MRl images of the head, facial skeleton and the spine are obtained
>■ the image is seen instantaneously on the monitor screen and recorded in the computer. The three-dimensional CT + M R 1

images of the head, facial skeleton and the spine, as the case may be, can be accurately visualized, (b) In case the patient requires both imaging and surgery :
> The same procedure as in (a) above, is followed, initially
> Thereupon, the marking of the flap, [ demar’ng the area on tfie brain which is to Be operated upon ] which is the most important initied step in neuro-surgery, in order to open the skull, is precisely done after imaging, on the Operating Table itself, after obtaining the three dimensional super-imposed CT + MRI pictures, which gives the bony details and the soft-tissue details of the brain. The 'helmef is now’ detached from the head-ring.
> Depending on the case, either the brain, the neck or the spinal cord will be operated upon
> During surgery,

• After marking the flap, the four burrs w’ith the burr-bits are placed in the slots available in the region of the upper case of the head ring.
• The skin flap is raised and the four burr bits are placed on the’kull to make four burr holes. The burr bits which are expauidable eavA retractable €ure placed and fixed in their respective positions, in order to prevent unnecessary movements. This fixation is done, utilizing the fixobur.
• If more than four burr-holes are required, the procedure is repeated again or more number of burr-slots may be provided in the same upper case of the head ring , so that simultaneously more number of biu-rs can be performed.

• The burr bits and the fixobur can be moved in their respective slots provided in the upper case of the head ring.
• The burrs are turned on and the procedure of making the burr holes is begun. The chambers for air and w’ater provided in the lower case of the head ring facilitates a pneumatic as w’ell as hydraulic power required for the burr to drill the hole in the bone.
• The lens inside the burr with the endoscopic light source gives an online image of the burring process. As soon as the dura is encountered, it is visualized as a pearly white glistening structure. At this point of time the burring procedure is stopped.
• Utilizing a separate bone-cutter, the four burr holes are joined together, so that a bone flap is raised.
• Utilizing the sonzir appeiratus, the tumor cind the blood vessels are visualized through the dural cover.
• The dura is opened and the operation on the brain is begun.
• The images are taken during surgery and seen on the monitor, £is an online imaging process, so as to prevent injury to the vital structures as alluded to earlier. The completeness of the resection and the amount of residual tumor available, can all be made out easily.
• The brain can be retracted, utilizing the self-reteiiiung retractors which are provide in the slots available for the very purpose in the upper case of the head ring.

• Per chance, any power cuts are encountered, the UPS or the battery available in the lower case of the head ring, takes over and facilitates uninterrupted surgery / imaging.
• A digital camera and an endoscope can also be fixed in the slot provided in the head ring for taking per-operative pictures and visualizing the inner comers of the resected area, by the endoscope, in the brain, which may not be possible by CT or MRI imaging.
• the extent of resection of the tumor is accurately defined
• the vascular structures, adjacent to the tumors, can be visualized exactly.
• the important arteries, veins, vital structures of the brain Uke the motor cortex, sensory cortex, auditory cortex, visual cortex, speech area, ventricles, breiin stem {xvitA tHe mid-6rain, pons and medulla o6Congata) , cerebellum and spinal cord can be spared from being damaged during surgery, due to accurate visueilization.

> The amount of residual tumor can be defined accurately
> The presence / absence of post-operative compUcations Woe haemotoma in the tumor bed / collection of blood wlack increases t6e pressure inside the Brain ] can be detected early after completion of the surgery before shifting the patient out of the operating table.
> When the neck or the spine [cervical dorsal lumSar or sacral] is being operated, the foldable spinal extension extending from the base of the 'helmef all along the length of the spinal column gives images, so that the surgical details are precisely localized.
