Description

Medical nipper under backbone scope with adjust binding clip angle function

Technical Field

The utility model belongs to the technical field of medical equipment, concretely relates to medical nipper under backbone scope with adjust binding clip angle function.

Background

With the development of modern spinal surgery technology, minimally invasive, intelligent, digital and precise surgical technologies become main development directions in the future, the development of the minimally invasive spinal endoscopy technology is more important, and compared with the traditional open surgery, the minimally invasive spinal endoscopic visual lumbar fusion has the remarkable advantages of small incision, less bleeding, less damage to lumbar vertebra structures, quicker postoperative recovery, less complications and the like in the treatment of lumbar degenerative diseases.

In the process of treating intervertebral disc space and establishing a bone grafting bed, some intervertebral disc soft tissues connected with bones to be cleaned are remained in the space, a cleaning tool generally uses a grasping forceps, the grasping forceps extend into the intervertebral disc space from a forceps rod to clamp out the remained tough soft tissues, in order to improve a wider visual field, the head end of the existing minimally invasive spinal endoscope uses a wide-angle lens, namely, the visual field seen through the endoscope is not just in front of the forceps rod, because the grasping forceps can only advance or retreat along the axial direction of the forceps rod, all the intervertebral disc soft tissues to be cleaned under the visual field of the wide-angle lens can not be clamped by the grasping forceps, in order to clean the soft tissues, the whole sleeve rod needs to be changed in a certain range in a human body or to expand a bone tissue channel and destroy intervertebral disc bone tissues so as to meet the requirement that the grasping forceps clamp can clamp all the remained intervertebral disc tissues to be cleaned, this can undoubtedly cause damage to the normal bone and soft tissue surrounding the patient's tunnel.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a medical nipper under backbone scope with adjust binding clip angle function, in order to solve present current nipper of proposing in the above-mentioned background art in the use, because nipper can only advance or retreat along the axial direction of tong pole, therefore, the intervertebral disc soft tissue of treating the clearance under the wide angle camera lens field of vision is not all can both be got by nipper clamp, just need to press from both sides whole telescopic pole change angle or expansion osseous tissue passageway and destroy the intervertebral osseous tissue in order to satisfy the clamp and get all remaining intervertebral disc tissues of treating the clearance, thereby can cause the problem of damage to normal bone and soft tissue around the passageway of patient.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a medical nipper under backbone scope with adjust binding clip angle function, includes fixed handle and tong pole, the front of fixed handle and the equal fixed mounting in the back have first articulated piece, the outside of first articulated piece articulates there is the activity handle, the top fixed mounting of activity handle has the second fixed block, the top fixed mounting of fixed handle has first fixed block, the one end fixed mounting that the handle was kept away from to fixed handle has the connecting pipe, the internal thread of connecting pipe articulates there is the telescopic link, the one end fixed mounting of tong pole has the articulated piece of second, the outside of the articulated piece of second articulates there is the binding clip, the inside fixed mounting of binding clip has the pincers tooth, the top fixed mounting in the binding clip outside has solid fixed ring, gu fixed ring's internally mounted has the wire that leads.

Preferably, the opposite sides of the fixed handle and the movable handle are fixedly provided with first limiting blocks, and torsion springs are fixedly arranged inside the first limiting blocks.
