Abstract

The invention discloses a quick-replaceable flexible surgical instrument for abdominal cavity minimally invasive surgery, relates to the field of medical equipment for thoracic and abdominal cavity minimally invasive surgery, and solves the problems that an existing surgical instrument cannot be positioned and subjected to posture adjustment by itself, and an end effector of the surgical instrument cannot be quickly replaced. The device comprises tail end operating forceps, a flexible joint device, a transmission box and a motor box. Flexible deflection is achieved by connecting the flexible joints in series through the pin shafts, mounting and dismounting of the flexible joints are facilitated, and the number of the flexible joints can be conveniently increased or decreased according to different operations; the flexible joint device is designed into a flexible bending structure, so that the working range and the flexibility of the surgical instrument in the body of a patient are improved; the transmission box and the motor box form a modularized driving assembly, so that the transmission box can be quickly mounted and dismounted, the driving is more flexible, and the whole structure is lighter; the driving assembly can be matched with various types of minimally invasive surgical instruments, so that the compatibility of the surgical instruments is improved, and the surgical application range is expanded.

Description

technical field [0001] The invention relates to the technical field of medical equipment for thoracic and abdominal minimally invasive surgery, in particular to a quick-change flexible surgical instrument for minimally invasive abdominal surgery. technical background [0002] Minimally invasive surgery is known as one of the important contributions of medical science to human civilization in the 20th century. Minimally invasive surgery means that the surgeon treats the patient's lesions with the help of surgical instruments and endoscopes by incising small holes in the patient's body surface. Compared with traditional surgery, minimally invasive surgery has the advantages of small incision, no secondary damage to the patient's body surface, and short recovery time. In recent years, robotic technology has been applied to minimally invasive surgery, and the robot-assisted minimally invasive surgery developed from this has improved the precision and flexibility of surgical ope...
