Problems solved by technology

[0004] Snake mouths can open up to swallow prey several times their own volume. Normally, human mouths can only open up to 30 degrees, but snake mouths can open up to 150 degrees. Therefore, it is of great significance to develop a bionic mechanism that can simulate the movement of snake mouths. , the search for the current patented technology has not found any relevant information on the research on the bionic mechanism of the snake mouth

Embodiment Construction

[0026] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0027] The bionic snake mouth mechanism of the present invention includes a head frame system capable of imitating the movement mode of the snake mouth, a power drive part and a motion conversion part. Overall structure of the present invention is as figure 1 As shown, its three-dimensional structure is as figure 2 shown.

[0028] The bionic snake head frame system includes an upper jaw closed-loop hinge mechanism 1 and a lower jaw component 3 . The upper jaw closed-loop hinge mechanism 1 is a four-link rocker mechanism with symmetrical structures on the left and right sides. 1 and 6-2 and two square bone rods 2 are formed. The parietal bone 4 is a frame-shaped component with a length of 60mm; the left and right sides of the front end of the parietal bone 4 are respectively hinged to one end of the two cuspid ro...

Abstract

The invention relates to a bionic snake mouth mechanism, which comprises a head frame system which can simulate the jaw motion of snakes, a power-driven part and a motion switching part, wherein a power source of the power-driven part passes through driving steel wires and is limited and guided by the motion switching part to draw an upper jaw closed loop articulated mechanism and a lower jaw component of the head frame system to move, so that a bionic snake mouth can be opened and closed. The bionic snake mouth mechanism can better simulate the motion mode of the snake mouth, has the advantages of simple structure, large motion space and the like, is easy to operate, can be used for the development of minimally invasive surgical instruments, surgical debridement, biopsy sampling and the like, and also can be popularized and used for various grabbing manipulators.

Description

technical field [0001] The invention relates to a bionic mechanism, in particular to a bionic snake mouth mechanism, which is used for the research on the movement mode of the snake mouth, and can be further popularized and applied to minimally invasive surgical medical devices for surgical debridement, biopsy sampling, etc., belonging to robots Technology and medical technology field. Background technique [0002] Bionics is the science of imitating living things to build technical devices. It is a new frontier science that combines biology, mathematics and engineering technology. In recent years, advances in bionics, robotics, biological anatomy, new materials and driving devices have promoted the development of bionic snake technology. [0003] At present, the bionic research on snakes mainly focuses on the limbless movement of snakes. The United States, Japan, Germany, Britain, France and other countries have all carried out research work on snake-shaped robots and deve...
