Embodiment approach

[0040] Such as Figure 2a and Figure 2b An embodiment of the shown actuating assembly, the actuating assembly 40 includes: an actuating block 41 arranged at one end of the operation cable 20 entering the jaw 12 and used for connecting the actuating block 41 with the A flexible link 42 to which all jaws 12 are connected.

[0041] When the operating cable moves along the axis of the working sheath in a direction away from the operating handle, the actuating block drives the flexible connecting piece, and then drives the ends of the clamps that are relatively close to the operating cable to approach each other, and the free ends of the clamps Separate in the direction away from each other. At this time, the clamps in the separated state can separate the necrotic tissue.

[0042] When the operating cable moves along the axis of the working sheath toward the operating handle, the actuating block retreats between the ends of the clamp that are relatively close to the operating ca...

Abstract

The invention provides a pair of noninvasive operating forceps, which comprise a forceps head, an operating cable for controlling the forceps head and a working sheath for wrapping the operating cable in a hollow structure; the noninvasive operating forceps further comprise an operating handle for controlling the operating cable to slide back and forth along the working sheath; the forceps head comprises a hollow sheath shell and at least two forceps clips, wherein the hollow sheath shell is connected with the end, relatively away from the operating handle, of the working sheath, and the forceps clips are arranged in the sheath shell and rotationally connected with the inner wall of the sheath shell. The tail end of the operating cable can enter the space between the forceps clips and is provided with an actuating assembly which can slide along the working sheath in a reciprocating mode along with control over the operating cable and drive the free ends of the forceps clips to achieve switching of the gathering state and the separating state.

Description

technical field [0001] The present disclosure specifically discloses a non-invasive surgical forceps. Background technique [0002] Choledochoscope is mainly used for endoscopic examination of pancreaticobiliary duct and endoscopic surgery, and it is more and more widely used in clinical practice. During the current choledochoscopic surgery for acute necrotizing pancreatitis, necrotic tissue removal and grasping are often required. In the process of cleaning up the existing necrotic tissue, there is no non-invasive surgical forceps through the choledochoscope, which needs to be improved urgently. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, the present application aims to provide a device that can separate and grasp necrotic tissue under a choledochoscope and minimize damage to normal tissues compared with the prior art. Atraumatic surgical forceps. [0004] A non-invasive surgical forceps, comprising: a cla...
