However, during the peristalsis of the gastrointestinal tract, the "B" shape is easily stretched by the tissue in a short period of time, which will cause the anastomosis to crack, form anastomotic bleeding, and anastomotic leakage; it even requires doctors to re-open the abdomen and suture manually, causing pain to the patient; serious failure

Embodiment Construction

[0012] Refer to attached figure 1 , 2 , prior art At present, the stapler usually utilizes the tightening force between the anastomotic component and the anvil to squeeze the thickness of the tissue to be anastomotic from about 4mm to 1.5-2.5mm, and then fires The titanium wire staple is formed into a "B" shape after passing through the anastomotic tissue (see the attached picture

[0013] 1). However, in the process of gastrointestinal peristalsis, the "B" shape is easily stretched by the tissue in a short time (see appendix figure 2 ), will cause anastomotic cracking, anastomotic bleeding, and anastomotic leakage; it may even require doctors to re-open the abdomen and suture manually, causing pain to the patient; severe cases may result in surgical failure.

[0014] Refer to attached image 3 , 4 , double O-shaped staples for staplers are composed of nail legs 2 and nail crown 1, and the upper part of nail crown 1 is formed with double "O"-shaped nail legs 2 (see atta...

Abstract

The invention relates to a double-O-shaped anastomosis staple for an anastomat, which is an anastomosis staple forming structure for the anastomat and applicable to the anastomats. The double-O-shaped anastomosis staple for the anastomat consists of a staple leg and a staple crown, and is characterized in that the double-O-shaped staple leg is formed at the upper part of the staple crown. The forming width W of the anastomosis staple is 3-4mm, the forming height H of the anastomosis staple is 1.5-2.5mm, the length L of the staple crown is 2-3mm, and the forming radius R of the staple leg is 0.35-0.95mm. The diameter phi of the cross section of the anastomosis staple is 0.2-0.3mm. The double-O-shaped anastomosis staple for the anastomat forms the shape of B during the gastrointestinal peristalsis process and is firmer and difficult to be propped up; and the anastomosis staple can ensure the good blood supply at the anastomosis for a nutrition blood vessel, be conductive to healing of the anastomosis and be conductive to rehabilitation of a patient.

Description

technical field [0001] The invention relates to a double O-shaped staple for a stapler, which is a staple forming structure for a stapler and is suitable for a stapler. Background technique [0002] At present, the stapler usually uses the tightening force between the anastomotic component and the anvil to squeeze the thickness of the tissue to be anastomotic from about 4mm to 1.5-2.5mm, and then fires. The titanium wire staple is formed into a "B" shape when passing through the anastomotic tissue. However, during the peristalsis of the gastrointestinal tract, the "B" shape is easily stretched by the tissue in a short period of time, which will cause the anastomosis to crack, form anastomotic bleeding, and anastomotic leakage; it even requires doctors to re-open the abdomen and suture manually, causing pain to the patient; serious The operation will fail. Contents of the invention [0003] The object of the present invention is to provide a double O-shaped staple for an...
