Abstract

The invention provides a modular multi-wire driving continuum lens arm based on a fixed pulley, and relates to the field of medical instruments. The invention aims to solve the problems that due to the rigid structure of a traditional rigid endoscope, lesion tissue cannot be observed in detail in the operation process, risks exist in the operation, and a continuum mechanical arm is high in flexibility but poor in load capacity. The modular multi-wire driving continuum lens arm comprises a driving end, a long guide rod, a modular continuum, an internal elastomer and a lens fixing end, one end of the long guide rod is connected with the driving end, the other end of the long guide rod is connected with the modular continuum, one end of the internal elastomer is connected with the lens fixingend, the other end of the internal elastomer sequentially penetrates through the modular continuum and the long guide rod, and the internal elastomer is a hollow elastic tube body. The modular multi-wire driving continuum lens arm is used for intraoperative operation monitoring.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a modular multi-wire driven continuum lens arm based on a fixed pulley. Background technique [0002] As people's pursuit of postoperative beauty becomes more and more intense, the application of minimally invasive surgery emerges. Minimally invasive surgery has the characteristics of small trauma, short recovery time, low medical cost and postoperative aesthetics. Minimally invasive surgery uses the natural orifice of the human body or makes a small wound on the surface of the human body, through which surgical instruments are inserted into the human body for surgical operations, usually requiring a rigid endoscope to assist the doctor in the surgical operation. The space of minimally invasive surgery is relatively narrow, the degree of refinement of operation is higher, and the flexibility of surgical instruments is higher. It is very difficult to observe the diseased tissue a...
