Problems solved by technology

However, at present, minimally invasive surgery cannot replace traditional open surgery. The reasons are: 1. The visual field of minimally invasive surgery is less intuitive than traditional surgery; 2. The flexibility of minimally invasive surgical instruments is far less than that of surgeons. Completing complex operations; 3. Minimally invasive surgery can hardly transmit the touch and pressure sensation during the operation
The above three reasons have become the bottleneck in the development of minimally invasive surgery at this stage, making the development of minimally invasive surgery stagnant

Embodiment Construction

[0033] Such as figure 1 , figure 2 , image 3 As shown, the present invention includes a working area 1 , an extension rod 2 , an operating area 3 and a base 4 . Wherein the working area 1 is located at the front end of the extension rod 2, including the working wrist 5, the first working finger 8 and the second working finger 9, one end of the working wrist 5 is rotationally connected with the front end of the extension rod 2 through the first shaft 6, and the other end of the working wrist 5 One end is rotationally connected with the first working finger 8 and the second working finger 9 through the second shaft 7 , wherein the first working finger 8 and the second working finger 9 can independently rotate around the second shaft 7 . The operating area 3 is located at the rear end of the extension rod 2 and includes an operating wrist 10, a first operating finger 13 and a second operating finger 14. One end of the operating wrist 10 is rotationally connected with the rear...

Abstract

The invention discloses a bionic surgical Instrument comprising a working area, an extending rod, an operation area and a base. The working area comprises five moving degrees of freedom, more approaches to the function of a human wrist and can finish actions and operations which traditional mini-invasive surgical instruments hardly finish or impossibly finish. In addtion, the operation area can sense the pressure of the working area and provide an operator with a certain basis for distinguishing tissues, organs, tumors and stones.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to a bionic surgical instrument. Background technique [0002] Since French doctors successfully performed the first laparoscopic cholecystectomy in 1987, minimally invasive surgery represented by laparoscopic surgery has experienced more than 20 years of development and has formed a relatively independent discipline, deriving thoracoscopy and pelvic endoscopy. , Arthroscopy and a series of minimally invasive surgeries. At present, minimally invasive surgery has become the most cutting-edge and most complex technology in surgery. A large number of advanced equipment, materials and instruments were first applied in this field. Minimally invasive surgery is also an important direction for the development of surgery in the 21st century. [0003] Minimally invasive surgery refers to making several perforations on the surface of the human body, and inserting the endoscope and ...
