Robotic arm for single-incision minimally invasive surgery

Abstract

The invention relates to the field of medical instruments and discloses a robotic arm for single-incision minimally invasive surgery. The robotic arm comprises a first drive component, a second drive component, a third drive component, a first executing arm, a second executing arm, an output mechanism and a control system, wherein the first executing arm and the second executing arm are respectively connected with the output mechanism, the first drive component, the second drive component and the third drive component are controlled by the control system to drive the first executing arm and the second executing arm to move synchronously so as to drive the output mechanism to move around a common point, and the common point is the intersection of a first axis passing the axis of the first executing arm and a second axis passing the axis of the output mechanism. The robotic arm for single-incision celiac minimally invasive surgery has the advantages that only one incision needs to be formed in the abdominal cavity, and the robotic arm is small in incision, low in pain, fast in postoperative recovery and the like as compared with a traditional multi-incision minimally invasive surgical robot; the application range of the robotic arm is not limited to the positions of human body natural orifices, and a wide application range is achieved as compared with the minimally invasive surgery performed through the human body natural orifices.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a mechanical arm used for single-hole surgery in minimally invasive surgery. Background technique [0002] In recent years, the concept of "minimally invasive" has penetrated into various fields of surgery. The so-called minimally invasive surgery, as its name implies, is an operation that only requires minimal trauma to the human body. It has the advantages of good wound appearance and so on, so it is widely welcomed by people. [0003] With the development of technology, medical staff usually use medical robots to complete minimally invasive surgery. At present, the widely used surgical robot on the market is the Da Vinci surgical robot. The Da Vinci surgical robot has several disadvantages, such as complicated operation, high cost, mechanical The most important thing is that the Da Vinci surgical robot needs to create multiple wounds on the body, and each additional wound w...
