Problems solved by technology

The unsatisfactory part of these two types of minimally invasive surgical instruments is that although the cables or metal sheets can drive the joint to bend to both sides, after the joint is bent to both sides, it is difficult for the joint composed of concave-convex joint pieces to be connected in any direction. The bending position has sufficient rigidity, so that the tool head of the minimally invasive surgical instrument is easy to shift and the positioning accuracy is poor

Abstract

A minimally invasive surgical apparatus provided with chain joints adopts the technical scheme that a joint is composed of the chain joints, teeth are arranged at two ends of chain plates of the chain joints and the teeth of each two adjacent chain plates in the same line are meshed with each other, and achieves the technical effects that the chain joints can be bent to two sides in a wide range and with a large curvature and are positioned accurately, and all bent parts are rigid enough. The minimally invasive surgical apparatus is suitable for stirring, separating, clamping, shearing, puncturing, suturing, nailing or looping tissues and organs of a human body or implants, can be used for dissecting and separating tissues, coagulation hemostasis or cutting tissues with electrotomes, and can be used as a draw hook after being bent and positioned.

Description

technical field [0001] The present invention relates to minimally invasive surgery with chain joints used in minimally invasive surgery for moving, separating, clamping, cutting, shearing, puncturing, suturing with needles and threads, nail clipping or trapping human tissues and organs and implants. Surgical instruments, especially those used in laparoscopic, endoscopic and hysteroscopic surgery for poking, separating, clamping, cutting, shearing, piercing, sewing, staples or snares of human tissue Minimally invasive surgical instruments with chain joints for organs, and more particularly relate to minimally invasive surgical instruments with chain joints for moving and separating human tissues and organs or hernia repair materials in hernia surgery, and more particularly relate to Minimally invasive surgical instruments with chain joints that move the tissues in the vertebral body during percutaneous vertebroplasty, and more particularly relate to microscopic surgical instrum...
