Embodiment 1

[0048] A bionic micro-clamp driven by vascularized artificial muscles, including a bionic micro-clamping mechanism 1, a vascularized helical artificial muscle 2, an electrode assembly 3, a concave base 4 and a cell culture solution 5;

[0049] The material used in the bionic micro-clamping mechanism 1 is SU-8 (3050), and the SU-8 (3050) layer with a thickness of 500 microns is formed according to the two-dimensional in-plane shape of the micro-clamping mechanism through a standard soft photolithography process. Cured on thin glass (thickness: 0.1 mm). Then the thin glass is peeled off to form a three-dimensional bionic micro-clamping mechanism 1 .

[0050] Described bionic micro-clamping mechanism 1 is made up of U-shaped section 11 and bionic micro-clamp arm section 12, and the bottom of U-shaped section 11 is a semicircular ring structure, and the inner radius of the ring is 750 microns, and the ring width (outer diameter minus inner diameter) size) is 700 microns. Two arm...

Abstract

The invention relates to a bionic micro-clamp driven by vascularized spiral artificial muscles, which belongs to the technical field of artificial micro-clamp devices. Including bionic micro-clamping mechanism, vascularized spiral artificial muscle, electrode assembly, concave base and cell culture medium; bionic micro-clamping mechanism consists of U-shaped section and bionic micro-clamp arm section, the bottom of U-shaped section is fixed on the concave base In the seat, the bionic micro-forceps arm section extends from the top of the U-shaped section; grooves are symmetrically opened on both sides of the U-shaped section; the vascularized spiral artificial muscle is formed by winding microfibers in the grooves; the microfibers There are biological microfibers and microchannels inside; skeletal muscle cells are wrapped in the biological microfibers, and the electrode device provides voltage for the skeletal muscle cells; when in use, cell culture fluid is injected from one end of the microfibers and flows out from the other end. The micro-clamps are used to perfuse and support the skeletal muscle cell group through the micro-channel, and electrically stimulate the relaxation / contraction of the skeletal muscle cell group to drive the bionic micro-clamping mechanism to open / close.

Description

technical field [0001] The invention relates to a bionic micro-clamp driven by vascularized spiral artificial muscles, which belongs to the technical field of artificial micro-clamp devices. Background technique [0002] Micro pincers are one of the common structures of shrimps, crabs, scorpions and other organisms in nature. Hundreds of millions of years of evolution have given the micro pincers of the above-mentioned organisms the advantages that current artificial systems cannot match, such as small size but high energy conversion efficiency Wait. Although the current artificial micro-clamp device has high operating precision, the internal operation mechanism is still mainly purely mechatronic. Miniaturization of the overall device is realized. [0003] In order to further improve the energy conversion efficiency of mechatronic micro-tweezers and at the same time realize the micro-bionic structure of artificial micro-tweezers, the research of life-like tweezers is curre...
