Mechanical arm having lifting function

Abstract

The invention relates to the field of medical equipment, and discloses a mechanical arm having a lifting function. The mechanical arm comprises a plurality of driving ropes, as well as a clamping mechanism, a first arm section, a second arm section and a third arm section which are sequentially connected, wherein the clamping mechanism, which is driven by the corresponding driving ropes, can be repeatedly opened / closed; the first arm section can drive the clamping mechanism to rotate relative to the second arm section; the second arm section can drive the first arm section to rotate relative to the third arm section; and the first arm section and the second arm section are different in rotating direction. The mechanical arm provided by the invention can be used in a mode of cooperating with an existing gastrointestinal endoscopy; a target mucosa can be lifted under the precondition of not changing the structure of the existing gastrointestinal endoscopy; therefore, the mechanical arm is beneficial for reducing requirements on personnel skills and experiences of doctors; and meanwhile, motion of the mechanical arm is not limited, and the motion flexibility of the mechanical arm is greatly improved in comparison with the existing double-apparatus-channel gastrointestinal endoscopy.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to an auxiliary device for digestive endoscopy, in particular to a mechanical arm. Background technique [0002] The traditional endoscopic mucosal cutting hand (ESD operation) refers to the cutting operation of the diseased mucosa by the gastroenterologist with the help of digestive endoscopy. At present, most of the commonly used endoscopes on the market are single-instrument channel endoscopes, which can only meet the cutting of the diseased mucosa, and cannot achieve the pulling action of the diseased mucosa while cutting it. Therefore, the doctor will Personal skills and experience are very demanding, which increases the risk of complications and operation time. Although there are digestive endoscopes with dual instrument channels that can perform lifting and cutting on the market, because the two instrument channels are parallel and coaxial, the lifting operation and cutting opera...
