Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly discloses an endoscope and microscope coupling air-water double-medium working channel.
Background
Minimally invasive spine surgery has the advantages of small tissue damage, low perioperative complication rate, early recovery, high cost effectiveness and the like, and among the existing spine minimally invasive techniques, microscope and spine endoscopy techniques are widely concerned. In recent years, with the rapid development of spinal endoscopes and channel technologies, a microscope technology using air as a medium, a single-hole single-channel coaxial endoscope using water as a medium, and a double-hole double-channel non-coaxial endoscope using water as a medium are created in succession, but the development of the channel technology under the microscope still remains in a working channel used for minimally invasive transforaminal fusion, which is the most classical minimally invasive version of transforaminal fusion. However, even when the endoscope and the channel technology are rapidly developed, the endoscope technology still has some difficult problems which are difficult to overcome, most spinal surgeons can only complete simple lumbar decompression operation by using the endoscope, and the repair and reconstruction of the spine, such as slippage reduction, spine fixation, under-lens fusion and the like, are forbidden, which is fundamentally caused by the self defects of the endoscope and the channel instrument. The microscope channel has a slightly larger caliber than an endoscope channel, belongs to a minimally invasive technology, can complete multiple operations of pressure reduction, fusion, fixation and the like under the channel, and has the defects of wider peeling range, more bleeding amount, stronger vision pertinence and the like compared with the endoscope channel. Therefore, in order to make up for respective short plates of a traditional microscope channel and an endoscope channel and promote the development of spinal microsurgery, the invention provides a microscope and endoscope coupling air-water double-medium working channel for minimally invasive spinal surgery.
Disclosure of Invention
The invention aims to provide an air-water double-medium working channel for coupling an endoscope and a microscope so as to solve the problem that the traditional microscope and the endoscope channel are insufficient.
In order to achieve the purpose, the basic scheme of the invention is as follows: the utility model provides an scope and microscope coupling air water bimedium working channel, includes the microscope passageway, and the microscope passageway upper portion outside is equipped with the handle, and the coaxial dismantlement in microscope passageway upper portion is connected with the top cap, and top cap one side is equipped with the vertical inlet tube of arranging, and the top cap opposite side is equipped with the vertical outlet pipe of arranging, and first through-hole, second through-hole, third through-hole have been seted up along the circumference equipartition in the top cap middle part.
The working principle of the basic scheme is as follows:
the body surface X-ray perspective positioning ensures that the responsibility segment is correct, skin and subcutaneous tissues are incised, surrounding muscles are separated along the muscle gap, after an operation area needing to be operated is found by reaching the bone surface, a channel is expanded step by using the step, a microscope channel is preferentially arranged, a handle is connected with an external fixing frame to fix the position of the channel, a top cover is installed and screwed, a water injection device is connected from the upper end of a water inlet pipe for water injection, a water outlet device is connected from the upper end of a water outlet pipe for water drainage, the visibility in the microscope channel is ensured through water circulation, a first through hole, a second through hole and a third through hole are formed, one endoscope opening can be formed in each of the three through holes, two operation openings are randomly distributed, and therefore the operations of articular process osteotomy under a water medium, vertebral canal decompression and the like are implemented. After the decompression operation is completed, the water inlet pipe is closed, the top cover is unscrewed, the water medium in the microscope channel is completely sucked by the aspirator, and the operations of fusion device implantation, vertebral body slippage and restoration, nail rod fixation and the like are completed under the air medium according to the operation requirement.
The beneficial effect of this basic scheme lies in:
(1) in the scheme, the top cover provided with the three through holes is detachably connected to the upper part of the microscope channel, so that the endoscope channel is ingeniously coupled with the microscope channel, the endoscope channel is a single-hole single-channel microscope channel and a single-hole single-channel non-coaxial endoscope channel, the endoscope technology and the microscope technology are combined into a whole, the common advantages of the two are fused, and the mutual defects are overcome;
(2) in the scheme, the top cover is provided with three through holes, the visual field is larger than that of the existing endoscope technology, more operations are performed, a special endoscope instrument is required to be used in the conventional endoscope operation, but under the working channel, an open operation spinal column instrument can be used, an endoscope operation instrument can also be used, and the open operation spinal column instrument and the endoscope operation instrument are both available;
(3) the scheme couples the endoscope channel with the microscope channel, realizes the absolute advantages of aqueous medium and air medium operation, and overcomes the technical defects that the lumbar endoscope operation vertebral body is difficult to slip and reset, the nail cannot be placed in the operation, the fusion cage cannot be implanted and the like.
Furthermore, the opening has been seted up at the top cap middle part, and coaxial seal can dismantle on the opening and be connected with the plectane, and the plectane is made for the elastic plastic material, and first through-hole, second through-hole, third through-hole are seted up on the plectane along circumference equipartition. The circular plate made of elastic plastic material can change the contact and friction between the surgical instrument and the three through holes from rigid contact to flexible contact.
Furthermore, the periphery of the circular plate is provided with a groove, the inner periphery of the opening is provided with a convex edge matched with the groove, and the groove is matched with the convex edge to realize the sealing connection between the circular plate and the top cover. The inner and outer buckle design between the top cover and the circular plate effectively avoids the possibility of water medium exosmosis, and simultaneously avoids the risk that the circular plate falls off due to the fact that instruments and endoscopes enter and exit a microscope channel.
Furthermore, one sides of the water inlet pipe and the water outlet pipe, which are close to the microscope channel, are attached to the inner wall of the microscope channel. This arrangement maximizes the operable operating space within the working channel.
Furthermore, one side of the lower part of the microscope channel, which is positioned on the handle, is a flat opening, and the other side of the lower part of the microscope channel is an inclined opening extending downwards. The inclined opening and the flat opening at the bottom of the microscope channel are designed to effectively enlarge the visual field area, reduce the occurrence of the situation that soft tissues such as muscles are clamped and pressed in the channel, and simultaneously, the operation of air medium can be further carried out on the basis of completing the operation of water medium, and the inclined opening and the flat opening can be switched freely under the necessary situation, thereby reducing the operation wound, reducing the bleeding amount in the operation and realizing the accurate operation.
