Abstract
The utility model discloses an ultra-thin lip and tiny tooth vertebral lamina rongeur, and relates to the orthopedic medical instrument, which includes a fixed handle, a flexible handle, a support replacement spring piece which can be flexible between the two handles, an upper slide claw beam, a lower fixed claw beam, an upper occluding lip and a lower occluding lip. The fixed handle is arranged with an arc embossment which one side is connected with a metal pressing board, the flexible handle is provided with a wavy dimpled grain, the bottom end of the upper occluding lip is arranged with a micro sawtooth, the top end of the lower occluding lip is also arranged with the micro sawtooth, the upper end surface of the lower fixed claw beam is arranged with a plurality of nonskid embossments. The utility model has thin lower lip and small size, which can reduce the latrogenic damages to vertebral canal nerves, reduce complications of surgeries, and make doctors grasp the clamp more comfortably and steadily. The utility model is applicable to various vertebral canal operations, in particular to the vertebral canal severe narrowing such as degenerations, tumors, hernias of intervertebral discs, etc.
Description
Technical field:
This utility model relates to medical surgical instrument, especially the orthopaedic medical treatment operating theater instruments.
Background technology:
Spinal column regression, spinal canal stenosis, canalis spinalis occupy-place are clinical very common diseases.Patient's spinal cord, nerve root have been in pressured state, the space is very limited inside the Pass the vertebra, compel to have only to sting except that vertebral plate and ligamenta flava and reduce pressure for removing nerve compression, yet when stretching into the laminectomy rongeur lower lip, above-mentioned tissue further occupies limited canalis spinalis space again stinging to remove, and the laminectomy rongeur lower lip that uses at present is thicker, cause the further crush injury of iatrogenic nerve easily like this, influence surgical effect.The spinal canal stenosis patient has vertebral plate to thicken more on the other hand, require great effort very much when stinging deossification, laminectomy rongeur handle because of general is thin and smooth again, the comfortableness deficiency, when hands is exerted oneself, be easy to generate laminectomy rongeur and rock, influence stability, especially art is wild little dark again in the intercalated disc videoendoscopic surgery, need more one-handed performance, to requiring higher with the pincers grip stability.
Existing laminectomy rongeur has following shortcoming:
1, lower lip is too thick, further occupies limited canalis spinalis space when stretching into the laminectomy rongeur lower lip again, causes iatrogenic entrapment injury easily like this, influences surgical effect.
2, hold the comfortableness of pincers and stable not enough with what clamp.
Very hard when 3, being used for vertebral plate and thickening the patient.
Summary of the invention:
The purpose of this utility model is to provide a kind of can the minimizing neurally go the iatrogenic crush injury of vertebral plate decompression process, and can be more comfortable be held in the hand, more stable during use, more laborsaving, reduce the ultrathin lip micro-tooth laminectomy rongeur of postoperative complication.
It comprises fixed handle (1), flexible handle (2), mobilizable support reseting spring leaf (3) between two handles, last slip claw beam (4), following fixedly claw beam (5), last interlock lip (6), following interlock lip (7), it is characterized in that: fixed handle is provided with an arc-shaped protrusions (8), projection one side connects metal pressing board (13), and undaform dimpled grain (9) is arranged on the flexible handle, and last interlock lip (6) lower end is provided with miniature sawtooth (10), following interlock lip (7) upper end is provided with miniature sawtooth (11), and the upper surface of following fixedly claw beam (5) is provided with some anti-slip projections (12).
Following interlock lip (6) thickness is less than 2mm.
Last interlock lip (7) lower surface is provided with miniature sawtooth (12), and following interlock lip (6) upper surface is provided with miniature sawtooth (11), upper and lower interlock lip (7), the interlock mutually of (6) little rack saw tooth.
Flexible handle (2) is provided with the waveform dimpled grain (9) that is complementary with the 2-5 finger.
Fixed handle (1) can be cylindrical radial or other arbitrary shapes, its rough surface, can be fuller be held in the palm.
Adopt metal material or other high-strength material to make.
Its advantage of this utility model is:
1, the laminectomy rongeur lower lip is thin, volume is little, can reduce iatrogenic injury neural in the canalis spinalis, reduces postoperative complication.
2, on the upper and lower interlock lip miniature sawtooth is arranged, the slit is not stayed in mutually interlock, can allow laminectomy rongeur sharper, operate more laborsaving, and minimizing operating time.
3, the compages of flexible handle and fixed handle not only can make the outer power of the sliding bar line of force that produces in the operating process cancel out each other between hands and pincers, and finally show as slip cutting force big as far as possible, line of force single stable.And it is more comfortable, more stable to allow the patient hold pincers.
4, provide a kind of safe, stable, operating apparatus efficiently for the intervertebral disc arthroscopic diagnosis.
Description of drawings:
Accompanying drawing 1 is a front view of the present utility model;
Accompanying drawing 2 is partial enlarged drawings of the upper and lower interlock lip of Fig. 1 leading section.
Partial enlarged drawing when accompanying drawing 3 is the interlock of the upper and lower interlock lip of Fig. 1.
The specific embodiment
Fixed handle (1), it holds metacarpus (14) is cylindrical radial (14), like this can be fuller be held in the palm; And rough surface, cause fish scale netted, increase coefficient of friction, be difficult for sliding; On fixed handle, be positioned at and hold metacarpus (14) top one arc-shaped protrusions (8) is arranged, the long approximately 2cm of projection holds that projection plays stable hand when clamping above the hands tiger, prevents the effect that hands slides upward; One side last at fixed handle (1), arc-shaped protrusions has the metal pressing board (13) of radian, the radian of metal pressing board (13), the concavo-convex form that meets thumb, metal pressing board (13) can be for thumb by putting, allow thumb also participate in holding pincers, and receive in the claw beam that produces can refer to play the part of flexible handle (2) with 2-5 the time and resist, the while does not influence the activity of flexible handle outside handle.Have on the flexible handle (2) and waveform dimpled grain (9) that 2-5 finger size is complementary, like this 2-5 refer to can be more stable, comfortable be placed on the flexible handle (2), and when playing the part of fixed handle position stability.Support reseting spring leaf (3) between two handles, last slip claw beam (4), end is connected with flexible handle, the lever principle that can be become by the set bolt between fixed handle (15) when flexible handle (2) shrinks, push away forward slide doing, sliding bar is gone up the cutting sclerotin that slides in anti-slip projection (12).Following fixedly claw beam (5) has anti-slip projection (12) on the following fixedly claw beam, anti-slip projection is long as far as possible, and the slip lip line of force is stable in the assurance.Comprehensively above-mentioned, this utility model makes pincers and hands reach big as far as possible stable mutually and coupling by many-side, the outer power of the sliding bar line of force that produces in the operating process is cancelled out each other between hands and pincers, and finally show as slip cutting force big as far as possible, line of force single stable.Last interlock lip (6) has miniature sawtooth (10) on it; Following interlock lip (7) has miniature sawtooth (11) on it, the slit is not stayed in the interlock mutually of little up and down tooth, and just as the canine tooth of animal, according to the relation of pressure and pressure, such interlock lip has more interlock and breaks through power, makes operation more laborsaving.Following interlock lip (7) thickness is thinner than existing, band transverse tooth thickness degree＜2mm, and length and width can take the volume of narrow canalis spinalis with existing identical or shorter as far as possible less.
