Automatic intestinal canal sectioning device

Abstract

The invention discloses an automatic intestinal canal sectioning device which is characterized in that at least one pair of guide rollers is arranged, an intestinal canal penetrates through the space between the two guide rollers, and when the two guide rollers rotate relatively, the intestinal canal is dragged and driven, and traction power is provided for the intestinal canal. The intestinal canal is guided and controlled in direction by the guide mechanism before passing through the guide roller, and the guide mechanism is used for guiding the intestinal canal into the guide roller in a preset direction. The cutting knife is arranged between the guiding mechanism and the guiding roller, the intestinal canal is tensioned between the guiding mechanism and the guiding roller, the cutting knife is provided with a V-shaped cutting edge, when the intestinal canal passes through the cutting knife, the side wall of the intestinal canal is sectioned through the V-shaped cutting edge, the intestinal canal is cut open to form a kerf, and the intestinal canal is automatically cut along with continuous traction and tensioning of the intestinal canal. According to the automatic sectioning device for the intestinal canal, the intestinal canal is tensioned for cutting through the guide roller and the guide mechanism, so that a guide rod structure does not need to be inserted into the intestinal canal, the intestinal canal with any diameter can be effectively cut, and the sectioning universality is improved.

Description

technical field [0001] The invention relates to the technical field of medical production, and further relates to an automatic intestine cutting device. Background technique [0002] Porcine small intestinal submucosa (SIS, Small Intestinal Submucosa) decellularized material is a matrix material with biologically active components obtained by removing the cell structure from porcine small intestine through a series of physical and chemical treatments. This new type of biomaterial is an important part of the scaffold material and the basic material in the field of tissue engineering and regenerative medicine. It has good biocompatibility and degradability, and retains a complete three-dimensional ultrastructure. Induce and promote the adhesion, proliferation and differentiation of surrounding cells, and the immigrated cells further transform, degrade and plasticize the material to achieve tissue formation and structural remodeling. [0003] The preparation process of SIS mai...

Problems solved by technology

During the pretreatment, firstly, the small intestine needs to be cut open along the mesenteric lateral line with scissors. This process requires manual operation and the cooperation of multiple people. The efficiency is low, and it is easy to cause damage to the SIS membrane. Moreover, the contents of the intestinal tract are dirty, and the working environment of the operator is very low. poor

[0004] Existing automatic intestinal dissection equipment usually requires the cooperation of guiding device, transmission device and cutting device, the mechanical structure is complicated, and the intestinal tube needs to be set on the guiding mechanism before cutting. There are differences. The guide mechanism with fixed diameter cannot adapt to the intestinal tube with large size difference. When dealing with the intestinal tube with too large or too small inner diameter, problems such as poor transmission or sliding displacement may occur, and the intestinal wall that is too thick or too thin may not It is beneficial to the clamping of the fixture, and the above problems will affect the cutting quality
