Abstract

A device for cutting a surgical cable including a handle side including first and second gripping members pivotally attached to one another, and an intervention side including an outer tubular member,an inner tubular member within the outer tubular member having a coupling member attached on a proximal end, and a movable pinion attached on a proximal end of the coupling member. The distal end ofthe second gripping member is attached to a proximal end of the movable pinion and the distal ends of the outer tubular member and inner tubular member have at least two openings that are off-center but substantially aligned to allow a surgical cable or wire to pass through and to exert a shearing force on the cable or wire when the inner tubular member rotates with respect to the outer tubular member in response to compressing the first and second gripping members.

Description

technical field [0001] Various exemplary embodiments disclosed herein generally relate to cutting tools for cables. Background technique [0002] A common requirement in orthopedic surgery is to anchor together two or more elements, such as bone fragments, two or more bones, or a combination of soft tissue and bone. This has been accomplished with a number of devices, such as bone bolts (which penetrate two bones and use nuts to pull the segments together), bone screws and interconnecting plates, wires encircling at least two bones, or sutures. [0003] Typically such devices require a relatively large access opening through the surrounding and / or overlying tissue to implant the anchoring device. The enlarged access site increases patient pain and prolongs recovery time. Furthermore, in some locations, it is difficult and impractical to create large access points to reach the proper site due to the surrounding joints and blood vessels. Even with a device that penetrates ...
