Robotic arm used for single hole abdominal minimally invasive operation

Abstract

The invention relates to the field of medical apparatuses, and discloses a robotic arm used for a single hole abdominal minimally invasive operation. The robotic arm comprises a first driving component, a second driving component, a third driving component, an output mechanism and a control system, wherein under the control of the control system, the first, the second and the third driving components jointly drive the output mechanism to move around a fixed point, and the fixed point is a public crossing point of horizontally crossing first and second axes and a third axis of the output mechanism itself. According to the single hole abdominal minimally invasive operation robot, only one surgical wound is made on the abdomen, compared with a traditional multi-hole minimally invasive surgical operation robot, the robotic arm has the advantages of being small in trauma, mild in pain, fast in postoperative recovery, well-looking in surgical wound and the like; meanwhile, the application range of the robotic is not limited by the position of natural cavities of the human body, the robotic arm has a wide application range than a minimally invasive operation through the natural cavities of the human body; the stability is good, the control is easy, and the cost is lower.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a mechanical arm for performing 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 the name implies, is an operation that only needs to cause minimal trauma on the human body. It has the advantages of small trauma, light pain, fast postoperative recovery and The wound is beautiful and other advantages, 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, The most important thing is that the Da Vinci surgical robot n...
