Natural orifice minimally invasive surgery controller having locking function

Abstract

The invention discloses a natural orifice minimally invasive surgery controller having a locking function. The controller comprises a control box shell which is connected to a front cover assembly, and a soft hose assembly which is connected to minimally invasive surgery tools so as to achieve operation supporting of the surgery tools and to assist the implementation of a minimally invasive surgery. The controller is a manual rotary controller which is based on cable driving; and the controller is provided with quick-change passages which support a plurality of minimally invasive surgery apparatuses, rotary switches which support multi-directional actions of the minimally invasive surgery apparatuses, a gear structure for locking up and opening the rotary switches, a triangular driving assembly which is matched with the cable driving and the like. The device (the controller) is convenient to operate, accurate in actions and good in real-time performance; the basic target of the minimally invasive surgery is achieved, the flexibility of motions is enhanced and the operating spaces of the surgery tools are widened, so that the minimally invasive surgery can be implemented rapidly and reliably.

Description

technical field [0001] The invention relates to a minimally invasive surgery controller, in particular to a natural orifice minimally invasive surgery controller with a locking function. Background technique [0002] In the process of solving the patient's illness, natural channel endoscopic surgery does not leave an incision on the surface of the human body, which reduces surgical trauma and postoperative pain, increases the cosmetic effect, and achieves better physiological and psychological minimally invasive effects. It will be the best choice for those who are obese, have poor physique, have scars and pursue high cosmetic effects. However, surgical instruments lack flexibility, and surgical images are two-dimensional imaging, which increases the difficulty of surgical operations. Therefore, surgical controllers based on natural orifices that can increase the flexibility of surgical instruments and provide three-dimensional surgical images have emerged. During minimall...

Problems solved by technology

During the operation, since the movement of the end of the surgical instrument and the movement of the hand-held part of the instrument have a special mapping relationship, in order to meet the action requirements of different surgical operation tasks (clamping, suturing, knotting, etc.), doctors need to manually operate surgical tools. The range of motion reduces the flexibility of the end of the tool to perform surgical actions. At the same time, long-term and large-scale operations make doctors prone to fatigue, which virtually increases the difficulty of surgery, and the requirements for surgical controllers also increase accordingly.
