Abstract

The invention discloses a laparoscopic surgical forceps. The forceps body assembly includes a tube body with a square inner cavity, the rotating shaft is fixedly connected with a clamp, and one end of the clamp is provided with an arc-shaped rack. The lifting plate is located on one side of the rotating shaft and is connected with the first reel for rotation. The outside of the first reel is fixed with an external gear meshing with the arc-shaped rack. The inner cavity of the first reel is provided with a protrusion fixed on the The fixed shaft on the outside of the plate, the outside of the fixed shaft is sleeved with a torsion spring, one end of the torsion spring is fixed on the outside of the fixed shaft, and the end of the torsion spring away from the fixed shaft is fixed on the inside of the first reel, so The outer side of the first reel is fixed with a traction rope, the outer side of the clamp is fixed with a pad, the side of the pipe body away from the raised plate is fixed with a fixed block, and the outer side of the fixed block is provided with a first insertion The slot and the second slot; the laparoscopic surgical forceps are composed of the forceps body assembly, the pull rod assembly and the handle assembly, which is convenient for disassembly and assembly of the laparoscopic surgical forceps, and is convenient for storage and storage.

Description

technical field [0001] The invention relates to the technical field of laparoscopic surgical forceps, in particular to a laparoscopic surgical forceps. Background technique [0002] Minimally invasive surgery is the most cutting-edge development direction of medical science and technology today. Minimally invasive surgery represented by laparoscopic surgery has gradually replaced traditional laparotomy. After more than 20 years of development, the technique of laparoscopic minimally invasive surgery has gradually matured. Because of its small surgical trauma, mild postoperative pain, short hospital stay, and good cosmetic effect, it has been widely used and satisfied in clinical practice. Effect. A laparoscope is an instrument with a miniature camera for intraperitoneal examination and treatment. It is essentially a fiber light source endoscope, including an energy system, a light source system, a perfusion system, and an imaging system. It uses a light source to provide i...
