Anastomotic stoma reinforcing assembly apparatus and stapler assembly for minimally invasive surgery

Abstract

The present invention relates to the technical field of staplers, and in particular, to an anastomotic stoma reinforcing assembly apparatus and a stapler assembly for minimally invasive surgery. Said apparatus comprises a reinforcing sheet assembly, a first reinforcing sheet support assembly, a second reinforcing sheet support assembly, and a staple cartridge assembly. The reinforcing sheet assembly is mounted at an upper portion of the staple cartridge assembly. The first reinforcing sheet support assembly is arranged inside the reinforcing sheet assembly. The first reinforcing sheet support assembly and the second reinforcing sheet support assembly cooperate to fix the reinforcing sheet assembly on the staple cartridge assembly. The lower end of the first reinforcing sheet support assembly is in clamped connection with the staple cartridge assembly. The upper end of the first reinforcing sheet support assembly is in clamped connection with the second reinforcing sheet support assembly. The present invention can not only ensure the stable connection between the reinforcing sheet assembly and the staple cartridge assembly, but also staple the upper and lower reinforcing sheets into the tissue by means of anastomotic staples, thereby improving the strength of the wound, avoiding bleeding and leakage of the wound, and reducing postoperative complications. The integrated connection between the reinforcing sheet and the endoscopic stapler assembly facilitates operation and reduces application defects caused by the falling, wrinkling, and twisting of the reinforcing sheet.

Description

Anastomosis reinforcement assembly device for minimally invasive surgery, stapler assembly TECHNICAL FIELD

[0001] The present application relates to the technical field of staplers, and particularly relates to an anastomosis reinforcement assembly device for minimally invasive surgery and a stapler assembly. BACKGROUND

[0002] Endoscopic staplers for minimally invasive surgery can staple tissue with staples while cutting, and are widely used in the reconstruction of organs such as intestines, stomachs, lungs and pancreases, and in the cutting, suturing or anastomosis of tissues. An endoscopic stapler comprises two parts, one part being a power component for firing (which can be manual, electrically driven or robotically powered), and the other part being an endoscopic stapler assembly. The endoscopic stapler assembly comprises a firing connecting rod assembly, a firing rod assembly, an articulation head assembly, a staple seating assembly, a staple cartridge assembly, and is also provided with a wire-type cutting knife for cutting tissue. The endoscopic stapler can form multiple rows of straight staple lines on tissue, and cut the tissue with the wire-type cutting knife to form a straight anastomosis incision. The use of such a device can facilitate the anastomosis and reconstruction of organs, and is usually used in lung, esophagus, intestine or gastrointestinal, liver and pancreas surgery. Compared with conventional open surgery, which first cuts with a scalpel or surgical scissors, the endoscopic stapler greatly reduces the risk of such a surgical procedure and shortens the operation time, and thus has a very wide application in surgical operations.

[0003] However, bleeding and leakage of anastomosis tissue cannot be completely avoided by the hard stapling of the staples alone. This is because the anastomosis staples are rigid structures that do not completely match the flexibility of soft tissue, resulting in bleeding at the staple holes and leakage at the closed cut end face (due to the friction between the metal anastomosis staples and the tissue, slow cutting, a certain proportion of complications of anastomosis fistula exist in the medium and long term). To solve the above problems, an anastomosis reinforcement sheet can be used in conjunction with a stapler, so that the stapler cuts and seals the wound surface at the same time, fixes the reinforcement sheet to the wound surface, blocks the staple holes, and improves the strength of the wound surface, thereby avoiding bleeding and leakage of the wound surface.

[0004] The prior art CN111466973A discloses an anastomosis stapler reinforcement pad assembly, which comprises an anastomosis part, a fixing part and a suture part. The anastomosis part is arranged on the anastomosis area of the anastomosis structure of the anastomosis stapler and is made of a degradable material. The fixing part is arranged on the non-anastomosis area of the anastomosis structure of the anastomosis stapler. The intersection of the anastomosis part and the fixing part is sutured by a suture line, so that when the anastomosis part realizes anastomosis of tissue with the anastomosis staples, the suture line is removed to separate the anastomosis part from the fixing part. However, the firmness of the connection between the anastomosis part of the above-mentioned anastomosis stapler reinforcement pad assembly and the anastomosis structure of the anastomosis stapler is not high, and when small-area tissue is stapled, the anastomosis staples that are not stapled to the tissue are easy to scatter in the patient's body, and it is not easy for the doctor to pick up the scattered anastomosis staples.
