Abstract

A micro instrument clamping mechanism for minimally invasive surgery comprises a gripper mechanism and a control mechanism which are connected through a carbon fiber tube. The gripper mechanism comprises a pair of grippers and a middle support with the top hinged to the pair of grippers and bottom hinged to a thread barrel, the control mechanism controls opening, closing and swinging in the same direction of the pair of grippers through a steel wire rope, and the control mechanism controls swinging of the middle support through a steel wire rope; the middle support is shaped like a cone, and a wiring groove is formed in the side wall of the middle support. Due to the fact that the middle support is shaped like the cone, the steel wire ropes are hidden in the wiring groove, and no other devices are arranged in the middle support, it is guaranteed that the whole gripper mechanism achieves smooth transition, no edge exists, and damage to the human body is avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a clamping mechanism for minimally invasive surgery. Background technique [0002] The invention patent with application number 201210011813.1 discloses a manual three-degree-of-freedom micromanipulator for minimally invasive surgery, including a fingertip clamping mechanism, a fingertip pitching mechanism, a rotation mechanism, and a handle. The fingertip clamping mechanism is installed on the fingertip On the pitching mechanism, the fingertip pitching mechanism is installed on the rotating mechanism, and the rotating mechanism is connected to the handle. The fingertip clamping mechanism includes a clamping shaft, a reset torsion spring, a traction bridge, a connecting plate, and two clamping pliers The two clamping jaws are installed together by a reset torsion spring to form a clamping head, the joint plate is connected with the reset torsion spring, the clamping s...
