Problems solved by technology

Typical minimally invasive surgical tools adopt a rod-driven transmission mode, and the front end has one degree of freedom, but the design of traditional minimally invasive surgical tools with only one degree of freedom determines that it cannot complete complex surgical operations, which limits the application environment of minimally invasive surgery
And in minimally invasive surgery, bipolar electric energy tools are mainly used for electrocoagulation and ele

Abstract

The invention provides a double-electrode forceps structure for minimally invasive surgery, comprising a first clamping end, a second clamping end and a multi-DOF (degree of freedom) joint. Driving force can be transmitted to a clamping mechanism through clamping wire ropes, pitching wire ropes and energy conductors, so that the clamping mechanism can provide the energy effect of pitching, deflecting and clamping free motions and operations. Compared with the prior art, the double-electrode forceps structure has the advantages that the two clamping ends are in embedded structure, and the functional and transmission needs and processing ends of the wire ropes and energy conductors can be satisfied in limited space; the clamping wire ropes are arranged close to one end, guide wheels are provided with large space for placement, the diameter of each guide wheel is enlarged, the service lives of the clamping wire ropes are extended, and equivalent allowable strength of each clamping wire rope is increased; the energy conductors are fixedly connected to the clamping mechanism and synchronously move with the clamping ends, the energy conductors experience less abrasion and have long service lives, and the service life of a micro instrument is prolonged accordingly.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bipolar forceps structure for minimally invasive surgery. Background technique [0002] With the continuous development of science and technology, minimally invasive surgical techniques are challenging traditional surgical techniques and gradually becoming the main theme in the field of surgical medicine in the 21st century. Minimally invasive surgery refers to the doctor sending medical equipment, physical energy, and chemical agents into the human body through minimal trauma or a small approach with the assistance of modern medical equipment such as thoracotomy and laparoscope to complete the resection and repair of diseased tissues. A type of operation such as surgery, reconstruction, etc. Compared with open surgery, minimally invasive surgery has many advantages such as less trauma, less bleeding, and faster recovery, and has been more and more widely used in c...
