Abstract
The utility model discloses nucleus pulposus clamps in a kind of lumbar vertebral canal.Including fixed handle, flexible handle, fixed link, motion bar, fixed pliers head, movable binding clip and axis pin, the front end of the fixed link is convexly curved, the front end of the fixed link is connected with fixed pliers head, the front end of the motion bar is convexly curved, the front end of the fixed pliers head and movable binding clip is in smooth shape, the bottom width of the fixed pliers head is more than the top width of fixed pliers head, the bottom width of the activity binding clip is more than the top width of movable binding clip, the top of fixed pliers head and movable binding clip still detaches when the bottom of the fixed pliers head and movable binding clip is closely engaged.The utility model can effectively take out the causes such as intraspinal tube nucleus pulposus pressure object, and can detach protection dural sac in operation, avoid dural sac fracture damage.
Description
Technical field
The utility model is related to the field of medical instrument technology, and in particular to nucleus pulposus clamp in a kind of lumbar vertebral canal.
Background technology
The protrasion of the lumbar intervertebral disci is the common disease of spinal surgery, and pathogenesis is that degeneration of intervertebral disc protrudes, compressing or thorn
Caused by swashing nerve, it is effective therapeutic scheme to be surgically removed cause pressure object.Some patientss interverbebral disc rear Anular disruption, marrow
Core takes off into falling to intraspinal tube, and between dural sac veutro and centrum rear wall, when operative treatment need to thoroughly take out.In default of special
The tool of door, detects free nucleus pulposus to patient's visual fields, then pass through conventional nucleus pulposus clamp repeatedly in operation by sharp keen hook
It takes out, since whole operation process can not look at straight, is easy to cause free nucleus pulposus residual, and hook and conventional nucleus pulposus clamp are easy damage
Hinder dural sac, lead to leakage of cerebrospinal, and serious complication occurs.
Invention content
In order to overcome the shortcomings of that existing Nuclectomy tool easy damaged dural sac, the utility model provide a kind of lumbar vertebrae vertebra
Interior nucleus pulposus clamp is managed, nucleus pulposus clamp not only can effectively take out the causes such as intraspinal tube nucleus pulposus pressure object in the lumbar vertebral canal, and operate
Cheng Zhongneng separation protection dural sacs, avoid dural sac fracture damage.
Technical solution adopted by the utility model to solve its technical problems is：Nucleus pulposus clamp in a kind of lumbar vertebral canal, it is special
Point be include fixed handle, flexible handle, fixed link, motion bar, fixed pliers head, activity binding clip and axis pin, the fixed hand
Handle, fixed link and fixed pliers head are integrally formed, and the front end of the fixed link is convexly curved, and the front end of the fixed link is connected with
Fixed pliers head, the flexible handle are integrally formed with motion bar, and the front end of the motion bar is convexly curved, the motion bar
Front end is hinged with motion bar by axis pin by axis pin connection activity binding clip, the fixed link, the fixed pliers head and activity
The front end of binding clip is in smooth shape, and the bottom width of the fixed pliers head is more than the top width of fixed pliers head, the adjustable clamp
The bottom width of head is more than the top width of movable binding clip, and the bottom of the fixed pliers head and movable binding clip is fixed when being closely engaged
The top of binding clip and movable binding clip still detaches.
The utility model has the beneficial effects that it is simple in structure, it can facilitate in narrow operating spaces and deep art area is carried out
Operation, and separation shape is at the top of binding clip always, dural sac is protected and detached, avoids damaging dura mater during crawl nucleus pulposus
Capsule is fast and safely effectively removed the free nucleus pulposus of intraspinal tube.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.

Specific implementation mode
In Fig. 1, nucleus pulposus clamp in a kind of lumbar vertebral canal, feature include fixed handle（1）, flexible handle（2）, fixed link
（3）, motion bar（4）, fixed pliers head（5）, movable binding clip（6）And axis pin（7）, the fixed handle（1）, fixed link（3）With
Fixed pliers head（5）It is integrally formed, the fixed link（3）Front end be convexly curved, the fixed link（3）Front end be connected with it is solid
Determine binding clip（5）, the flexible handle（2）With motion bar（4）It is integrally formed, the motion bar（4）Front end be convexly curved, institute
State motion bar（4）Front end pass through axis pin（7）Connection activity binding clip（6）, the fixed link（3）With motion bar（4）Pass through axis pin
（7）It is hinged, the fixed pliers head（5）With movable binding clip（6）Front end be in smooth shape, the fixed pliers head（5）Bottom
（9）Width is more than fixed pliers head（5）Top（8）Width, the activity binding clip（6）Bottom（9）Width is more than movable binding clip
（6）Top（8）Width, the fixed pliers head（5）With movable binding clip（6）Bottom（9）Fixed pliers head when close occlusion（5）With
Movable binding clip（6）Top（8）Still detach.
In fig. 2, the fixed pliers head（5）With movable binding clip（6）Front end is smooth, the bottom of binding clip（9）It is wide and binding clip
Top（8）It is narrow.Fixed pliers head shown in Fig. 3（5）With movable binding clip（6）When closure, the bottom of binding clip（9）Close occlusion, and clamp
The top of head（8）It still detaches, avoids Clamping damage dural sac.
In use, patient holds fixed handle（1）And flexible handle（2）, by fixed pliers head（5）With movable binding clip（6）It stretches
Enter dural sac veutro, the wherein bottom of binding clip（9）It is bonded centrum rear wall, the top of binding clip（8）Positioned at dural sac facies ventralis, patient
During crawl dissociates nucleus pulposus, the bottom of binding clip（9）Nucleus pulposus, the top of binding clip are captured by occlusion（8）Separation protection is hard
Membrane vesicle is fast and safely effectively removed the free nucleus pulposus of intraspinal tube to realize.
