Embodiment Construction

[0032] The technical means adopted by the present invention to achieve the predetermined purpose of the invention are further described below with reference to the drawings and preferred embodiments of the present invention.

[0033] like figure 1 As shown, the medical degradable stapler provided in an embodiment of the present invention is made of degradable magnesium or magnesium alloy material, and includes two identical anastomotic rings. Road match. Specifically, each anastomotic ring body 10 is provided with a plurality of fixing needles 11 , a plurality of fixing buckles 12 and a plurality of locking grooves 13 ; wherein, the plurality of fixing needles 11 are evenly arranged on the anastomotic surface of the anastomotic ring body 10 ( That is, the opposing joint surfaces of the two anastomotic ring bodies 10) are used to fix the intestinal tissue to prevent the intestinal tissue from moving during anastomosis; a plurality of fixed buckles 12 are evenly arranged on the...

Abstract

The invention discloses a medical degradable stapler and a preparation method thereof. The stapler is made of degradable magnesium or magnesium alloy, and comprises two identical anastomosis rings. Aplurality of fixing pins are arranged on each anastomosis ring, a plurality of fixing buckles and a plurality of clamping grooves, and the fixing pins are uniformly arranged on the anastomotic surfaces of the anastomosis rings and used for fixing intestinal tissue and preventing the intestinal tissue from moving during anastomosis. The fixing buckles are uniformly arranged on the anastomotic surfaces of the anastomosis rings, and the clamping grooves are formed in the outer sides of the anastomosis rings; the fixing buckle of one anastomosis ring is clamped to the clamping groove of the otheranastomosis ring, so that the fixing pins on the anastomosis rings fix the intestinal tissue to achieve anastomosis. The stapler is convenient to use, firm in fixing, capable of facilitating development and degradable after operations, avoids unnecessary inflammation, caused by long-time retention of metal sundries in the human body, of affected parts, greatly shortens the operation time of patients and greatly reduces postoperative infection risks and the economic burden of the patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical degradable stapler, and also to a preparation method applied to the medical degradable stapler. Background technique [0002] Intestinal anastomosis is an important technique for reconstruction of the gastrointestinal tract in gastrointestinal surgery. The ideal intestinal anastomosis not only requires a firm and safe anastomosis, but also requires easy operation and no foreign body residue as much as possible. Anastomotic rings are mainly used in small bowel tumors, colon tumors, intestinal obstruction, intestinal trauma, intestinal perforation, colon cancer and other diseases. [0003] At present, the most commonly used method for intestinal anastomosis is stapler anastomosis. After the stapler is used, intestinal stenosis and other conditions will occur, and the staples used in the stapler are titanium alloys, which are permanently left in the body, which ine...
