Height-adjustable screw abutting seat component mechanism

Abstract

The invention discloses a height-adjustable screw abutting seat component mechanism. A plurality of pin holes are formed in a screw abutting seat. Kidney-shaped holes which are arranged up and down are formed in the corresponding portions of the pin holes in a screw abutting seat frame. Clamping grooves are formed in the portions, corresponding to the kidney-shaped holes, of an adjusting piece. Guiding pins are inserted in the claming grooves, the kidney-shaped holes and the pin holes in sequence. The adjusting piece is provided with a sliding face which is connected with the screw abutting seat frame in an abutting mode. The clamping grooves are formed obliquely relative to the sliding face. A plurality of locating embedding grooves which are matched with the guiding pins are formed in one sides of the clamping grooves. When a pushing button is pushed to make the adjusting piece move, the guiding pins slide in the clamping grooves, the guiding pins are respectively clamped on the corresponding locating embedding grooves during a moving process, and meanwhile the screw abutting seat moves up and down in the screw abutting seat frame by matching of the guiding pins and the kidney-shaped holes. The height-adjustable screw abutting seat component mechanism can adjust the closing height of a stapler, different requirements for forming heights of stapler screws are met, and accordingly suture operations on tissue of different thicknesses can be well carried out.

Description

technical field [0001] The invention relates to a height-adjustable nail anvil assembly mechanism, which belongs to the field of medical instruments. Background technique [0002] At present, when the linear cutting stapler in the traditional mechanical stapler performs surgery, the anvil frame and the anvil in the anvil part are fixed structures, and different staple cartridges need to be selected to solve the problem of the thickness of the sutured tissue , such a structure requires high interchangeability of our staple cartridge components, which increases the processing accuracy of the components, complicates the processing of the components, and easily leads to the formation of staples during the suture process. Inconsistency will eventually lead to some complications such as anastomotic leakage after suture, poor blood supply of the tissue after anastomosis, and high surgical risk. Contents of the invention [0003] The technical problem to be solved by the present ...
