Oval unequal length anastomotic nail turning cover tubular anastomat

Abstract

An oval unequal length anastomotic nail turning cover tubular anastomat relates to a surgical operation instrument. The oval unequal length anastomotic nail turning cover tubular anastomat is provided with a movable handle, an anastomat body, an oval nail drill, an oval nail bin and a nail drill pipe. The front end of the anastomat body is connected with the oval nail drill, the rear end of the anastomat body is connected with the movable handle, and the oval nail bin is provided with an oval nail box, an oval nail base, a first group of anastomatic nails and a second group of anastomatic nails. The top of the oval nail drill is movably connected with the nail drill pipe, an included angle between a top long shaft of the oval nail drill and the nail drill pipe is larger than 90 degrees, an included angle between a top short shaft of the oval nail drill and the nail drill pipe is equal to 90 degrees, and the length of the first group of anastomatic nails is 35-95% as large as that of the second group of anastomatic nails. The operability of the oval nail base and the operability of the oval nail box are relevant, and the oval nail base is movably connected with the oval nail box in an anastomotic mode.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a flip-top tubular stapler with elliptical and unequal-length staples. Background technique [0002] At present, tubular staplers are widely used in surgical operations and have been used for decades. However, such staplers have always had problems such as anastomotic leakage, anastomotic bleeding, and staple residue after anastomosis in clinical use. The applicant discloses a sandwich stapler type alimentary tract anastomosis cutter closure device for suturing tissues in Chinese patent CN102813540A. It is provided with a movable handle, a body extending from the end of the handle, a staple box and a membrane connected to the end of the body; the staple box is provided with a nail box, a nail seat, a first set of staples and a second set of staples Staples, the length of the first group of staples is 5% to 95% of the length of the second group of staples; the membrane directly contacts t...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the anastomotic stretch is reduced after adding the film, it is not easy to remove the nail drill (seat) from the intestinal tract after anastomosis

[0004] 2. When the anastomosis is performed, because the strength is easy to grasp improperly, it is easy to cause blood circulation disorder and necrosis of the intestinal wall in the anastomosis area
