Surgical stent device for gastrointestinal surgery

Abstract

The invention discloses a surgical stent device for gastrointestinal surgery. A movable block is fixedly connected to the right end of a first piston rod, a sliding groove is slidingly connected to the lower end of the movable block and fixedly connected with a transverse rod, and the upper end of the movable block is rotatably connected with the lower end of a second hinge rod; the upper end of aleft sleeve block is rotatably connected with the lower end of a first hinge rod, the first hinge rod is rotatably connected with the middle of the second hinge rod, the upper end of the second hingerod is rotatably connected with the lower portion of the left side of a platen, the upper end of the first hinge rod is rotatably connected with the lower portion of a sliding block, and a guide railis slidingly connected to the upper end of the sliding block and fixedly connected with the lower portion of the right side of the platen. The device drives sleeve blocks and the transverse rod to move left and right in the direction of a groove as a whole under the threaded applied force through a rotating lead screw, the platen, a second hydraulic cylinder and a clamping ring are driven to moveleft and right accordingly, the first hinge rod and the second hinge rod rotate to lift or lower the platen, the clamping ring ascends or descends along with the platen to achieve height adjustment,and a turntable is rotated to drive the second hydraulic cylinder to rotate to adjust the rotation angle of the clamping ring.

Description

technical field [0001] The invention relates to a medical tool, in particular to a surgical support device for gastrointestinal surgery. Background technique [0002] The stomach becomes the most important organ for digestion, and almost all the nutrients needed by the human body need to pass through the stomach. On the 20th day of human embryonic development, the gastrula tubes in the embryo form the front and rear intestines head to tail, and the midgut forms the midgut. Later, the midgut disappears, and the foregut forms the pharynx, esophagus, stomach, duodenum, jejunum, and most of the proximal ileum; the hindgut develops into a small portion of the distal ileum, cecum, appendix, colon, and rectum. The endoderm of the gastrula tube is derived into the epithelium of the alimentary canal, various small digestive glands, liver, pancreas, thyroid, parathyroid, thymus, and epithelium of the respiratory tract. [0003] At present, it is very troublesome to adjust the height...

AI Technical Summary

Problems solved by technology

[0003] At present, it is very troublesome to adjust the height and left and right of the existing gastrointestinal surgery brackets during use, and the structure is quite complicated, with many electronic components and high failure rates, and most of them cannot adjust the rotation angle
