Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly relate to a kind of foramen intervertebrale lens.
Background technology
The object of foramen intervertebrale lens vertebral column minimally invasive technology sets up service aisle from patient body side or proceeds posterolateral to enter intervertebral foramina, by outside intervertebral foramina triangle of safety district, annulus fibrosus disci intervertebralis, thorough removing is given prominence to or the sclerotin of the vertebral pulp that prolapses and hypertrophy removes pressure to nerve root, remove due to intercalated disc give prominence to oppress cause lateral crypt circulation be obstructed, nerve root edema and aseptic inflammation again, causes clinical symptoms to recur.Its operation method is by the foramen intervertebrale lens of particular design and corresponding supporting minimally invasive spine surgical apparatus, imaging and image processing system and bipolar coagulation, ozone therapeutic apparatus, a minimally invasive spine surgical system of common composition.
Perform the operation in the descending local anaesthesia puncture of patient's waking state, minor skin otch completes, noiseless to intraspinal tube, outstanding degeneration nucleus pulposus is taken out under foramen intervertebrale lens, wound is little, do not destroy paraspinal muscle, ligament, do not affect spinal stability, clearly can observe canalis spinalis and nerve root by foramen intervertebrale lens, direct view under endoscope takes out outstanding degeneration nucleus pulposus.While thoroughly excising outstanding or prolapsus vertebral pulp, removing hyperosteogeny, treatment spinal canal stenosis, the fibrous ring etc. that radio-frequency technique repairing can be used damaged.Because foramen intervertebrale lens vertebral column minimally invasive technology is performed an operation outside fibrous ring, therefore farthest can keep the integrity of fibrous ring and keep the stability of spinal column, the operation of the minimally-invasive treatment prolapse of lumbar intervertebral disc minimum to patient trauma in similar operation, effect is best, is called the ultimate therapy of intervertebral disc prolapse by external spinal column expert.
But currently used foramen intervertebrale lens, its instrument channel is closed-type circular passage, operating theater instruments needs to stretch into focus from instrument channel, therefore the size of apparatus must be less than the size of instrument channel, thus make the apparatus size that uses under foramen intervertebrale lens very little, not only inefficiency, and intensity is low, is easy to damage.In addition, the passage in the agent structure of foramen intervertebrale lens is also enclosed circular channel, when inserting operating theater instruments, is not easy the front end alignment apertures of apparatus, makes operating theater instruments insert inconvenience.Therefore design one and can not increase mirror pipe diameter, but can support that the foramen intervertebrale lens of larger apparatus has very large clinical value.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of foramen intervertebrale lens, add operating theater instruments inserted mode, the tool bit part cut and organized can make larger size, thus increases work efficiency and the intensity of operating theater instruments, make operation technique simpler, efficient, operating theater instruments is durable in use.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of foramen intervertebrale lens, it is characterized in that: the working lens pipe comprising agent structure and be connected with described agent structure one end, described working lens pipe and described agent structure are provided with the instrument channel running through whole foramen intervertebrale lens two ends, and the sidewall of described instrument channel is provided with an opening.
Further, described working lens pipe is also provided with shooting passage, at least one illumination channel, waterflood path and drainage channel.
Further, described agent structure is provided with and the video-frequency connector of described shooting channel connection, the fibre-optical splice that is communicated with illumination channel, the water supply connector be communicated with described waterflood path, the drainage joint be communicated with described drainage channel.
Further, the cross section of described working lens pipe is crescent.
Further, described opening longitudinally runs through whole instrument channel.
Further, the limit in the cross section of described instrument channel and described opening is made up of one section of circular arc and two sections of straight lines tangent with described circular arc, and the two ends of described circular arc are connected with one section of straight line respectively.
Further, the Breadth Maximum of described open cross-section and the ratio of working lens pipe external diameter are 1:3-3:4.
Further, the front end of described working lens pipe is provided with by the downward inclined-plane of described opening part.
Further, the angle between the straight line at described inclined-plane and described opening place is 90-135 degree.
Further, described water supply connector and described drainage joint are equipped with for opening and closed controlled valve.
The present invention adopts the instrument channel of bypass, the mode making operating theater instruments enter foramen intervertebrale lens increases, no longer that mode is interted in unique front and back, and can entering apparatus from the side opening of foramen intervertebrale lens, then operation path is entered together with foramen intervertebrale lens, therefore when not changing foramen intervertebrale lens size, tool bit part for tissue cutter tool can make larger size, thus shorten operating time, increase work efficiency and the intensity of working portion, make operation technique simpler, efficient, operating theater instruments also becomes more durable in use.
