Abstract
The present invention relates to a special knife for an intervertebral disc operation, which belongs to the class of medical appliances. The special knife for an intervertebral disc operation is provided with structures, such as a cutting tool provided with a positioning needle rod and an outer sleeve, etc.; therefore, the present invention can achieve accurate positioning, accurate excision depth, accurate control range of an annular cutting edge and neat incision. Besides, the slide of the cutting tool can be avoided, and thus, medical accidents caused by accidental injuries of the operations can be fundamentally eliminated.
Description
The present invention relates to the special-purpose cutter of a kind of intervertebral disc, belong to medical mechanical domain.
Prolapse of lumbar intervertebral disc is the commonly encountered diseases of surgery, and this disease serious operate as normal that influences the patient, living and studying cause secular misery to the patient.And be to pass through surgical operation therapy to the most effective Therapeutic Method of prolapse of lumbar intervertebral disc.But because the region of anatomy of lumbar intervertebral disc is darker, so intervertebral disc operation all carries out under the condition of limited exposing very, vertebral lamina fenestration intervertebral disc marrow nuclear excising art particularly: the area of outstanding annulus fibrosus disci intervertebralis excision is very little, be spinal cord, nerve root and epidural lacuna vein blood vessel net on every side, owing to this vasoganglion fills, expands because of the inflammatory repetitious stimulation, bring great difficulty to operation.Scalpel that this type of operation of present stage is used all is the general surgery scalpel, exposes extremely condition of limited at operative site and uses this general surgery cutter, and usefulness point of a knife circular resection annulus fibrosus disci intervertebralis is difficult to controlling depth, dynamics and excision extension.When particularly on the human intervertebral disc fibrous ring bulging being arranged, the easier generation of scalpel is slided during excision, and Spinal Cord and nerve root cause malpractice, make patient's permanent disbility.
A kind of scalpel for intervertebral disc operation is provided, adopts the ring-like closed edge of a knife, avoid the accidental injury of the edge of a knife other tissue; Positioner is set, makes scalpel be difficult for producing slip, thereby remedy the deficiency of prior art.
The object of the present invention is achieved like this: scalpel for intervertebral disc operation, it is characterized in that: at first be provided with the location shank, the shank front end is provided with positioning needle in the location, shank is outside equipped with Tubular tool in the location, the cutter front end has blade, cutter front end outer periphery is equipped with some annular grooves, and spring positioning ring is arranged on the groove.
Described scalpel for intervertebral disc operation is characterized in that the Tubular tool end periphery is provided with handle of a knife.
Scalpel for intervertebral disc operation provided by the invention owing to adopted said structure, can be accomplished accurate positioning, the excision degree of depth is accurate, and the circular blade span of control is accurate, and otch is neat and tidy, and, accidentally injure the malpractice that causes thereby fundamentally eliminated operation owing to avoided the cutter slip.
Below by embodiment, in conjunction with the accompanying drawings the present invention is further described:
Embodiment:
In the drawings: 1 is the location shank, and 2 is positioning needle, and 3 is Tubular tool, and 4 is blade, and 5 is handle of a knife, and 6 is groove, and 7 is spring positioning ring.
During use, the fibrous ring thickness situation that need excise according to the patient is selected a groove 6 earlier, puts spring positioning ring 7; Intervertebral disc operation is opening operation, after exposing limited operative site, earlier the positioning needle 2 of location shank 1 front end is inserted the fibrous ring center fixation that needs excision, again Tubular tool 3 is slipped into from the rear end of location shank 1, make blade 4 under the positioning action of location shank 1, entangle the excision position accurately, reuse holds handle of a knife 5 firmly, can make blade 4 excision fibrous ring positions, if in the excision process, fibrous ring and posterior longitudinal ligament have calcification and when becoming hard, can use hammer hammering handle of a knife 5.In this process, because first estimating depth has used spring positioning ring 7, so when Tubular tool 3 reached capacity the degree of depth, spring positioning ring 7 can be stuck in the tissue around the fibrous ring, make blade 4 not pass intervertebral disc forward again and damage the abdominal part trunk and pierce intervertebral disc.After the fibrous ring excision is finished, take out nucleus pulposus and reach therapeutic purposes with the vertebral pulp pincers.
Claims (2)
1, scalpel for intervertebral disc operation is characterized in that: at first be provided with the location shank, the shank front end is provided with positioning needle in the location, shank is outside equipped with Tubular tool in the location, the cutter front end has blade, and cutter front end outer periphery is equipped with some annular grooves, and spring positioning ring is arranged on the groove.
2, scalpel for intervertebral disc operation as claimed in claim 1 is characterized in that the Tubular tool end periphery is provided with handle of a knife.
