Abstract

The invention discloses a nail anvil, which overcomes the defect that the wound of the nail anvil used by an end-to-end annular cutting anastomat on a life body is larger. The nail anvil comprises a center rod, a cap body and an annular cutter anvil, wherein the center rod is rotationally connected with a connecting part arranged on the cap body, an eave part is arranged on the center rod, a stop block is arranged on the end surface of one end, connected with the connecting part, of the center rod, a torsional spring is elastically arranged between the eave part of the center rod and the connecting part of the cap body, and the part of the end surface of one end, which extends out of the center rod and is connected with the connecting part, of the stop block is pressed on the cap body by the annular cutter anvil, so that the cap body is propped on the center rod. The nail anvil provided by the embodiment of the invention has the advantages that the wound size during the end-to-end annular cutting surgery can be reduced, the damage to the wound is reduced, the wound healing difficulty is reduced, and the wound healing time and the life body recovery time after the surgery are shortened.

Description

technical field [0001] The invention relates to medical equipment, in particular to a nail anvil. Background technique [0002] At present, various end-to-end circumcision staplers have been more and more widely used in surgical operations. The end-to-end circumcision stapler is mainly used to suture the lumen tissue with anvil and other equipment, which can greatly shorten the operation time and significantly improve the operation efficiency. [0003] When the end-to-end circumcision stapler is in use, the purse bags are sewed on the respective ends of the two sides of the lumen to be anastomosed, and then the stapler is inserted from one side of the lumen so that the purse bag on this side of the lumen is tightened. On the pulling rod of the stapler; and embed the anvil into the other side of the lumen, so that the purse on the other side of the lumen is tightened on the central connecting rod of the anvil. By operating the stapler and the anvil, the purse strings on bot...
