Clamp applicator for anastomosis

Abstract

The invention discloses a clamp applicator for anastomosis, which comprises a clamp head assembly, a clamp rod assembly and a clamp handle assembly. The clamp head assembly and the clamp handle assembly are installed at both ends of the clamp rod assembly. The clamp head assembly includes The first pincer head of the first half tube of the hoop can be clamped with the second pincer head of the second half tube of the hoop tube, the second pincer head is pivotally connected with the first pincer head, and the pincer handle includes first pincer pins that are pivotally connected to each other. The clamp handle and the second clamp handle, the opening and closing of the first clamp handle and the second clamp handle drives the opening and closing movement of the first clamp head relative to the second clamp head. The clip applicator tailored by the present invention for "a clamp applier for anastomosis" can fill the blank of the current "clamp clip applier for anastomosis" without clamping state, and greatly improves the use of laparoscopic hemostasis. Inconvenience caused by pliers operation.

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...
