Abstract
The invention discloses a micromanipulator for enterocoelia minimally invasive surgery, relating to a micromanipulator for minimally invasive surgery. The invention solves the problem of the shortage of micromanipulators in surgical equipment of existing enterocoelia minimally invasive surgery. In the invention, a lower clutch dial is installed on the upper end face of a tooth-form central spindle of a driving box, an upper-finger upper clutch dial of a traction mechanism of the upper finger at the tail end of the manipulator is contacted with a corresponding lower clutch dial of the driving box; a lower-finger upper clutch dial of the traction mechanism of the upper finger at the tail end of the manipulator is contacted with the corresponding lower clutch dial of the driving box; a wrist upper clutch dial of the traction mechanism of the wrist at the tail end of the manipulator is contacted with the corresponding lower clutch dial of the driving box; and an autorotation upper clutch dial of an autorotation mechanism at the tail end of the manipulator is contacted with the corresponding lower clutch dial of the driving box. The micromanipulator of the invention is convenient for rapidly exchanging surgery tools, thereby increasing the nimbleness of surgery action, and meeting the requirements in various aspects such as size, function and clamping force an the like on the micromanipulator, thus being applicable to enterocoelia minimally invasive surgery.
Description
technical field [0001] The invention relates to a micro manipulator for minimally invasive surgery, which belongs to the technical field of medical equipment for surgery. Background technique [0002] Minimally invasive surgery refers to the operation performed on the human body through a minimum small incision. The minimally invasive surgical technique emerged in the 1980s and is generally called interventional surgery. Interventional surgery uses a variety of visual image equipment and advanced and smart surgical equipment to insert surgical instruments into the human body through small incisions for treatment or diagnosis. Compared with traditional open surgery, minimally invasive surgery has many advantages such as less trauma, less pain for patients, faster postoperative recovery, better operation quality and lower medical costs. Therefore, being generally welcomed by doctors and patients is an inevitable trend in the development of surgery. Minimally invasive abdomin...
