Abstract

The utility model discloses a dark sword of intervertebral disc rotary -cut limit, it includes the rotary cutter and the handle of a knife of a body coupling, rotary cutter's rotary cutter sword designs according to archimedes spiral, the diameter of handle of a knife is greater than rotary cutter's diameter. The utility model discloses a dark sword of intervertebral disc rotary -cut limit, the operation technique in -process can be accurate restriction rotary cutter's the rotary -cut degree of depth, improve surgical precision. Do and the wicresoft's neck, the prolapse of lumbar intervertebral disc operation rotary -cut ware wicresoft, effective that adopt the dark sword of this rotary -cut limit to make efficiently reach 90~95%, can alleviate intervertebral disc pressure maybe will stick out the nucleus pulposus and take out, electronic high -speed rotary -cut, the misery is little, destruction is little, it is fast to resume, the postoperative does not have obvious scar.

Description

A kind of intervertebral disc rotary-cut limits deep cutter

Technical field

This utility model belongs to medical instruments field, is specifically related to a kind of intervertebral disc rotary-cut and limits deep cutter.

Background technology

Flank pain is typically to be caused by the lumbar intervertebral disc of bulging, and lumbar intervertebral disc plays the work of pressure between buffering lower waist section vertebral body With, owing to damage or naturally-aged, the outer wall of intervertebral disc or fibrous ring can produce degeneration, this allows for intervertebral disc central authorities marrow Nuclear matter can be expanded and form bulging, and the position of this bulging can be oppressed or stimulate to nerve, and causes lumbago and skelalgia, logical Cross the access technology referred to as percutaneous puncture lumbar intervertebral disc suction of a kind of Wicresoft and cut art, by lancet puncture to prominent under the monitoring of C-arm In the lumbar intervertebral disc gone out, then extracting nook closing member, insert rotary cut device and carry out rotary-cut, peeling knife head is threaded, and passes through suction function By part nucleus pulposus out, thus make the nucleus pulposus highlighted return in the fibrous ring including intervertebral disc in, make the intervertebral highlighted Dish recovers normal, and then releases perineural induced pain pressure, eliminates the symptom of lumbago and skelalgia.This treatment technology has following Advantage: (1) Wicresoft, effectively, effective percentage reaches 90～95%；(2) dmm can be alleviated maybe to be taken out by prominent vertebral pulp；(3) Electric high-speed rotary-cut；(4) misery is little, it is little to destroy, recover fast, postoperative without obvious cicatrix.The knot of Wicresoft's electronic intervertebral disc rotary cut device Structure includes electric handle, collecting bin and peeling knife, but the rotary-cut degree of depth that existing peeling knife is during rotary cutting removes can only It is monitored by the scale of depth being located on peeling knife handle of a knife, but operative process cannot limit peeling knife accurately The rotary-cut degree of depth, once in operation process, rotary-cut is the deepest, cutter head can be made to pass the fibrous ring of intervertebral disc, affect surgical effect, because of This needs to provide a kind of intervertebral disc rotary-cut to limit deep cutter.

Utility model content

The purpose of this utility model is to provide a kind of intervertebral disc rotary-cut to limit deep cutter.

Another object of the present utility model is to provide a kind of Wicresoft neck, lumbar intervertebral disc operation rotary cut device.

The purpose of this utility model can be achieved through the following technical solutions:

A kind of intervertebral disc rotary-cut limits deep cutter, and it includes peeling knife and the handle of a knife integrally connected, the peeling knife of described peeling knife Sword designs according to spiral of Archimedes, and the diameter of described handle of a knife is more than the diameter of described peeling knife.

A kind of Wicresoft neck, lumbar intervertebral disc operation rotary cut device, it includes that handle, collecting bin and above-mentioned intervertebral disc rotary-cut limit are deep Cutter, is provided with micromotor in the inner chamber of described handle, the handle of a knife that described intervertebral disc rotary-cut limits deep cutter is micro-with described by collecting bin The rotary shaft of type motor connects.

The intervertebral disc rotary-cut of this utility model design limits the diameter diameter more than its peeling knife of deep cutter handle of a knife, and its handle of a knife is straight Footpath is bigger, during carrying out rotary-cut, can limit the rotary-cut degree of depth.

The beneficial effects of the utility model:

The intervertebral disc rotary-cut of this utility model design limits deep cutter, can limit peeling knife in operative process accurately The rotary-cut degree of depth, improves operation precision.And use this rotary-cut to limit Wicresoft's neck that deep cutter is made, lumbar intervertebral disc operation rotary cut device Wicresoft, Effectively, effective percentage reaches 90～95%；Dmm can be alleviated maybe taken out by prominent vertebral pulp；Electric high-speed rotary-cut；Painful little, Destroy little, recover fast, postoperative without obvious cicatrix.

Accompanying drawing explanation

Fig. 1 is that intervertebral disc rotary-cut limits deep knife structure figure.

Fig. 2 is Wicresoft's neck, the structure chart of lumbar intervertebral disc operation rotary cut device.

Detailed description of the invention

As it is shown in figure 1, a kind of intervertebral disc rotary-cut limits deep cutter, it includes peeling knife 1 and the handle of a knife 2 integrally connected, described rotation The rotary-cut blade of cutting knife 1 designs according to spiral of Archimedes, and the diameter of described handle of a knife 2 is more than the diameter of described peeling knife 1.

The intervertebral disc rotary-cut of this utility model design limits the diameter diameter more than its peeling knife 1 of deep cutter handle of a knife 2, its handle of a knife The diameter of 2 is bigger, during carrying out rotary-cut, can limit the rotary-cut degree of depth.

As in figure 2 it is shown, a kind of Wicresoft neck, lumbar intervertebral disc operation rotary cut device, it includes handle 3, collecting bin 4 and above-mentioned vertebra Intercalated disc rotary-cut limits deep cutter, is provided with micromotor in the inner chamber of described handle 3, and described intervertebral disc rotary-cut limits the handle of a knife 2 of deep cutter and passes through Collecting bin 4 is connected with the rotary shaft of described micromotor；Drive intervertebral disc rotary-cut to limit deep cutter by rotary shaft and carry out rotary-cut.

In operation process, by lancet puncture to prominent lumbar intervertebral disc under the monitoring of C-arm, then extract pin Core, inserts intervertebral disc rotary-cut and limits deep cutter and carry out rotary-cut, by suction function by part nucleus pulposus out, thus make to highlight Nucleus pulposus returns in the fibrous ring including intervertebral disc in, makes the intervertebral disc highlighted recover normal, and then releases perineural induced pain Property pressure, eliminate lumbago and skelalgia symptom.This operation process Wicresoft, effectively, effective percentage reaches 90～95%；Intervertebral disc can be alleviated Prominent vertebral pulp is maybe taken out by pressure；Electric high-speed rotary-cut；Misery is little, it is little to destroy, recover fast, postoperative without obvious cicatrix.
