Method and apparatus for forming stoma trephines and anastomoses

Abstract

The present invention relates to a stapler apparatus, comprising a stapler having a proximal end, a distal end and a longitudinal axis, the stapler further comprising a trigger, an anvil docking pin aligned substantially parallel with the longitudinal axis of the stapler, and a stapling means, the anvil docking pin and stapling means being at the distal end of the stapler, and a detachable anvil, comprising an anvil head and an anvil shaft, wherein the anvil shaft is adapted to receive the anvil docking pin and operation of the trigger causes the stapling means to be actuated, characterised in that the length of the anvil shaft is at least 4 cm. The present invention also relates to a method of forming an anastomosis between two surfaces using the stapler apparatus of the invention and a method of forming a stoma trephine in a subject using the stapler apparatus of the invention.; The present invention further relates to the use of the stapler apparatus or anvil for a stapler apparatus in such methods and a kit of parts comprising the stapler apparatus of the invention and additional components.

Description

Technical field [0001] The invention relates to a method and a device for generating trephine and anastomosis in a cavity in traditional open surgery and laparoscopic surgery. Background technique [0002] A large number of diseases require segmental resection to remove part of an organ. For example, inflammatory bowel disease (such as Crohn's disease, ulcerative colitis), colorectal cancer, and bowel infarction may require removal of part of the lower digestive (gastrointestinal) tract. After resection, the two ends of the gastrointestinal tract must be connected to each other to maintain the functioning of the organs. This rejoining process is called surgical anastomosis. [0003] A stoma is an artificial opening between two hollow organs or between a hollow organ and the body. The production of artificial stoma, such as colostomy, ileostomy, urethostomy, esophagostomy and gastrostomy, can be a very useful medical intervention in the treatment of diseases, especially for norma...

AI Technical Summary

Problems solved by technology

[0013] In the lower rectum, especially the last 10 cm and especially the last 5 cm, the excision of the lesion pathology and the subsequent l cavity anastomosis are problematic with traditional suturing techniques because the position of the anal resection is extremely low relative to the anal position or in the The perineal cavity created in the APPEAR procedure does not have enough space for adequate docking of the opposing anvil shaft and trocar (anvil butt pin)
