Embodiment Construction

[0022] The external connector and the main part of the tissue scissors are disassembled and cleaned, and then autoclaved. The front end of the external connector is nestedly connected to the main body of the tissue scissors, the water inlets and outlets on both sides of the external connector are respectively connected to the water inlet and outlet pipes, and the light source interface and image output interface are respectively connected to the water washing system and the TV image system. Turn on the light source and TV imaging system. The thumb and ring finger are respectively inserted into the upper and lower handle rings. When the thumb moves down, the connecting rod is pushed up, and the force axis closes to form a "one" shape. When the thumb moves up, the movable handle is separated from the fixed handle, the connecting rod is pushed down, and the cutting blades are opened. After accurately determining the tissue to be cut, separated or cut off, the thumb pushes the up...

Abstract

The invention belongs to a medical instrument and relates to a pair of portable tissue scissors with a micro visual structure, which is applied to minimally invasive surgical operations, comprises a tissue scissors main body, the micro visual structure and an external connector, and is characterized in that the direction conversion of the force is realized through the adoption of an articulation piece and an X-shaped ruff so as to meet the special requirement for operation in a tiny passage; the micro visual structure made of light-weight soft material internally comprises a water out-in flush passage, an optical fiber and a camera image transmission passage and can provide good view for operation, which brings convenience in operation; and connectors of the external connector and those of the micro visual structure are in one-one correspondence and in directional and positioning design, so that the mounting and dismantling are very convenient and simple. The pair of portable tissue scissors can be used for cutting off, separating and removing of downlink tissues in the tiny operation passage.

Description

[0001] technical field [0002] The invention relates to a portable tissue scissors for surgical operations, in particular to a portable microscopic surgical scissors. The microscopic structure can provide a good field of vision for the tissue scissors under the tiny surgical channel. [0003] Background technique [0004] Traditional tissue scissors can only be performed in open surgery, but open surgery has disadvantages such as large trauma, heavy bleeding, fear of surgery for patients, and long-term chronic pain after surgery. In recent years, endoscopic surgery has developed rapidly, and various endoscopes have been used clinically. [0005] However, the cutting edge and handle of the traditional tissue scissors have a cross-type mechanical conduction mode. When the rear handle is opened to a large lateral diameter, it is impossible to perform tissue cutting operations in the tiny surgical channel. In order to solve this problem, we designed this micro-vision Struct...
