Abstract

The invention provides an auxiliary stretching device for endoscope surgery and relates to the technical field of medical apparatus and instruments. The device comprises one or more stretching parts,each strength part comprises two oppositely-arranged flexible coils, and liquid metal is placed in each flexible coil; the two ends of each flexible coil are electrically connected with an external power supply, the directions of current connected into the two flexible coils in the same stretching part are identical or opposite, when the directions of the current are identical, the two flexible coils in the same stretching part attract each other and are in a closed state, and when the directions of the current are opposite, the two flexible coils in the same stretching part repel each other and are in a stretched state. According to the auxiliary stretching device for endoscope surgery, current is provided for the two flexible coils in the same stretching part, the magnetic field is generated, change at the closed and stretched states is achieved, the complication caused by pneumoperitoneum can be effectively avoided, an operator conveniently and effectively removes mist generated byenergy equipment and bleeding, and the surgical range is enlarged.

Description

technical field

[0001] The invention relates to the technical field of medical instruments, in particular to a flexible stretching device. Background technique

[0002] With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open operations in the past have now been replaced by endovascular surgery. Greatly increased surgical options. As a newly developed minimally invasive surgical method, laparoscopic surgery has the advantages of small trauma, fast postoperative recovery, and small abdominal incision scar, and is very popular among patients. Therefore, minimally invasive surgery is the general trend and goal of surgical development.

[0003] Laparoscopic surgery is to make several small incisions in different parts of the abdomen, insert camera lens and various special surgical...
