Anastomosis hooping cylinder clip applier

Abstract

The invention discloses an anastomosis hooping cylinder clip applier. The clip applier comprises a forceps head assembly, a forceps rod assembly and a forceps handle assembly; the forceps head assembly and the forceps handle assembly are installed at two ends of the forceps rod assembly; the forceps head assembly comprises a first forceps head capable of being connected with a first half cylinderof a hoop cylinder in a clamped mode and a second forceps head capable of being connected with a second half cylinder of the hoop cylinder in a clamped mode; the second forceps head is pivoted to thefirst forceps head; forceps handles comprise a first forceps handle and a second forceps handle which are pivoted with each other; and the first forceps handle and the second forceps handle open and close to drive the first forceps head to open and close relative to the second forceps head. The disclosed clip applier is customized for an anastomosis hooping cylinder, can fill up the blank that a conventional anastomosis hooping cylinder does not have a clip applier, and greatly improves the inconvenience caused by the operation of conventional endoscopic hemostatic forceps.

Description

technical field [0001] The invention relates to the field of medical surgical equipment, in particular to a surgical operation auxiliary device applied to digestive tract anastomosis, especially for the intrathoracic gastroesophageal anastomosis process of transorally implanted nail-anvil system in minimally invasive esophageal cancer radical resection A hoop clamp applicator for anastomosis. Background technique [0002] During the operation of digestive tract reconstruction, it is usually necessary to shrink the stump of the digestive tract so that the main body of the stapler and the anvil will not come out, and the two segments are in full contact during the anastomosis so that no side holes are left after the anastomosis. Especially in the minimally invasive radical resection of esophageal cancer, the peroral implantation of anvil system (Orvil TM ) in the process of gastroesophageal intrathoracic anastomosis, the treatment of the esophageal stump is more difficult due...
