Abstract

The invention relates to a multiple degrees of freedom flexible motion arm mechanism in the technical field of minimally invasive surgeries, comprising a three-level assembly body, a mechanical skeleton and two-level flexible finger mechanisms, wherein the three-level assembly body is fixedly arranged in the mechanical skeleton, and the two-level flexible finger mechanisms are arranged in the centers of the mechanical skeleton and the three-level assembly body. The invention has multiple degrees of freedom as well as small and exquisite volume and is provided with only one operation instrument with flexible multilevel fingers so as to further reduce the pain of a patient and accelerate the recovery rate.

Description

technical field [0001] The invention relates to a device in the technical field of minimally invasive surgery, in particular to a multi-degree-of-freedom flexible operating arm mechanism. Background technique [0002] Micro-operating system technology is widely used in the medical field. The most promising application of micro-operating system technology in medical treatment is invasive minimally invasive treatment. In some current technologies, catheter-based diagnosis and treatment are very popular. Although a number of commercial catheter techniques are available, catheter techniques have limited bending angles and present significant risk to the patient. [0003] Minimally invasive surgery refers to surgery performed using modern medical instruments such as laparoscopy and thoracoscopic surgery and related equipment. Minimally invasive surgery does not require surgery, and only needs to open 1-3 small holes of 0.5-1 cm in the patient's body. The patient does not leave s...
