Extra-cavity anastomotic method and ectropion type extra-cavity anastomat

Abstract

The invention provides an extra-cavity anastomotic method. The extra-cavity anastomotic method includes enabling two broken ends of a hollow organ to be anastomotic to penetrate from intermediate through holes from a nail bin and a base relatively and reversely overturning outwards to expose the anastomotic positions of the two broken ends, sewing the anastomotic positions of the two broken ends by sewing nails and excising the residual ectropion part of the hollow organ by a rotary cutter. The invention further provides an ectropion type extra-cavity anastomat. An outer casing is a three-way pipe, a nail bin is fixed in a nail bin connecting pipe, the base and the nail bin are coaxially and relatively arranged, and the axes of the nail bin and the base are parallel to the axis of a base connecting pipe; the nail bin and the base are annular, a ring cutter is mounted in the nail bin and embedded in the end face of the nail bin and can axially move in the nail bin, and the end face of the base is provided with a ring slot matched with the ring cutter. The nail bin and the base are not coaxial with the outer casing, the two broken ends of the hollow organ to be anastomotic conveniently penetrate the intermediate through holes of the nail bin and the base, and extra-cavity anastomosis is realized.

Description

technical field [0001] The invention relates to a stapler and belongs to the technical field of medical instruments. Background technique [0002] In medical work, when performing surgery on patients, especially some cavity organs, such as esophagus, stomach, small intestine, large intestine, rectum and other parts, staplers will be used. When the lesion is removed during the operation, it will Anastomose the stumps together, and use an endoluminal stapler for the anastomosis of the stumps of the hollow organs, and perform an inversion anastomosis of the stumps, or use a linear cutting stapler. When the intracavitary stapler is used, it needs an opening to put in the stapler. The opening includes the natural opening and the cavity organ has another opening. The natural opening is selected from the rectum, and the anus is the most selected opening. Inserting the anus, this method is easy to cause anal contamination, and then the upper esophagus, the opening of which is selec...

Problems solved by technology

When the intracavitary stapler is used, it needs an opening to put in the stapler. The opening includes the natural opening and the cavity organ has another opening. The natural opening is selected from the rectum, and the anus is the most selected opening. Inserting the anus, this method is easy to cause anal pollution, and then the upper esophagus, the opening of which is selected from the oral cavity, and the stapler is inserted from the oral cavity, which also has the problem of contamination, and the structure of the oral cavity is complex, which is not conducive to the insertion of the stapler

When other parts are anastomotic, it is necessary to make an incision on the hollow viscera to put in the stapler. After the anastomosis is completed, the stapler is drawn out, and then the incision is made with a linear slit cutter, which not only increases the trauma, but also increases the operation steps and operation costs, and may Increased chance of complications
