Description

Arthroscope management sleeve with suture

Technical Field

The utility model relates to the field of surgical instruments, in particular to a suture management sleeve for an arthroscope.

Background

Arthroscopic surgical devices generally include the following systems: camera systems (cold light sources, monitors); a power planing system (a power main machine, a planing mobile phone and a planing tool bit); a radio frequency ablation system; various surgical instruments (cannulas, manual instruments: graspers, scissors, biters, wire graspers, probes, files, etc., CL cruciate ligament reconstruction instruments). The arthroscopic surgery is a minimally invasive surgery, relates to each joint such as knee joint, shoulder joint, elbow joint, hip joint, wrist joint and ankle joint, and has two functions of treatment and diagnosis.

With the development of medical technology, minimally invasive surgery is more and more popular, and in the minimally invasive surgery, an instrument for providing an access channel is needed, and an access cannula can meet the requirement. However, the existing access casing technology has the following problems: the sealing structure in the access casing mostly adopts a single sealing valve structure, the clinical use effect is common, the backflow of the physiological saline is serious in the operation process, and the operation is interfered; the suture thread drawn out of the body of the patient cannot be placed properly, a messy state after swinging is easy to occur, and a doctor generally distinguishes the suture thread by color, but the mode is not favorable for long-term memory, and the situation of suture thread confusion is easy to occur; due to the limitation of the sealing structure at the front end of the access sleeve, the access sleeve can only be used as a passage for fixing some surgical instruments (such as a wire grasper, an obturator, a suture and the like), and the adaptable surgical instruments are limited. The above conditions greatly affect the clinical use experience of the access cannula and limit the use function thereof.
