Tubular anastomat with pull wire

Abstract

The invention provides a tubular anastomat with a pull wire, and relates to a surgical instrument. The tubular anastomat is provided with a movable handle, an anastomat body, a nail drill, a nail bin, a nail drill rod and the pull wire. The front end of the anastomat body is connected with the nail drill. The rear end of the anastomat body is connected with the movable handle.

The nail seat is connected with the nail box in a movable and matched mode. The number of the pull wire is at least one. The pull wire is arranged at the front end of the anastomosis nail. Anastomotic stoma tissue can be pulled downward and inward through the pull wire under the condition that anal dilatation is sufficient, the pull wire is nailed to an anastomotic stoma at the same time after simulative anastomosis, the anastomotic stoma can be strengthened and sutured with the help of the pull wire through the anus, the pull wire serves as a supporting wire which supports and pulls the anastomotic stoma tissue through the anus, the purpose of completely eliminating anastomotic leakages is achieved, the international medical problems that an existing tubular anastomat has low rectum anastomotic leakages and an anastomotic stoma leaks easily in a low rectal cancer operation particularly are solved, a patient is free from pain of two operations, and medical expenses are lowered.

Description

technical field

[0001] The invention relates to a surgical instrument, in particular to a tubular stapler with a pull wire. Background technique

[0002] At present, due to the high incidence of postoperative anastomotic leakage (about 10% to 20%) in low rectal cancer sphincter-preserving surgery in medical surgery, most patients use proximal colon or small enterostomy in the first radical operation to reduce the incidence of anastomotic leakage. Occurrence of rectal anastomotic leakage. After the first operation, the patient needs to undergo the second preventive ostomy restoration, which not only causes the pain of the second operation for the patient, but also increases the economic burden of about 30,000 yuan.

[0003] The applicant disclosed in Chinese patent 201310374625.X an oval tubular stapler with unequal length staples flip cover, which is provided with a movable handle, a device body, an oval nail drill, an oval nail magazine and a nail drill rod; The front end...
