Detailed Description

Further advantages and effects of the present utility model will become apparent to those skilled in the art from the disclosure of the present utility model, which is described by the following specific examples.

Please refer to the accompanying drawings. It should be understood that the structures, proportions, sizes, etc. shown in the drawings are for illustration purposes only and should not be construed as limiting the utility model to the extent that it can be practiced, since modifications, changes in the proportions, or otherwise, used in the practice of the utility model, are not intended to be critical to the essential characteristics of the utility model, but are intended to fall within the spirit and scope of the utility model. Also, the terms such as "upper," "lower," "left," "right," "middle," and "a" and the like recited in the present specification are merely for descriptive purposes and are not intended to limit the scope of the utility model, but are intended to provide relative positional changes or modifications without materially altering the technical context in which the utility model may be practiced.

As shown in fig. 1 to 5, the tubular digestive tract stapler of the present embodiment includes: a stapling seat 100 and a stapling body 200 connected to the stapling seat 100; an annular groove 110 is formed on the top surface of the nail propping seat 100; the nail supporting seat 100 is provided with an anastomotic stoma isolating protection structure which is an annular isolating protection film 300; the isolating protection film 300 is sleeved on the outer side surface of the nail propping seat 100, the upper portion of the isolating protection film 300 is accommodated in the annular groove 110, the lower portion of the isolating protection film 300 covers the bottom surface of the nail propping seat 100, and the end surface of the lower portion of the isolating protection film 300 is fixed inside the nail propping seat 100.

In the operation process, a doctor fixes two ends of the intestinal tract which need to be anastomosed in a cutting groove, rotates an adjusting knob 210, withdraws a nail pushing seat 100, clamps intestinal tissues 1, presses a firing handle 220 to push out an annular knife 510 and a nail pushing sheet 520, and the annular knife 510 cuts off the inner redundant intestinal tissues 1 and the lower part of an isolation protective film 300; the staple pushing sheet 520 pushes out staples, the staples pass through the intestinal tissue 1 and the isolation protection film 300, pass through the guide groove on the staple pushing seat 100, are extruded into a B shape, the staples are meshed with the intestinal tissue 1 and the isolation protection film 300, finally, the adjusting knob 210 is reversely rotated, the intestinal tissue 1 is loosened, the tubular gastrointestinal stapler is withdrawn, at the moment, the isolation protection film 300 is unfolded after being pulled, and the isolation protection film 300 covers the anastomotic stoma downwards, so that the protection effect is achieved. The isolation protection film 300 is arranged on the tubular digestive tract anastomat, and the isolation protection film 300 can provide a mask and a protection effect for a cut wound at an anastomotic site, isolate the bacterial environment of the intestinal tract and prevent postoperative infection of the anastomotic stoma.

The arrangement of the isolation protective film 300 does not affect the original anastomosis operation of the tubular digestive tract anastomat; and the isolation protective film 300 is unfolded, so that the operation of anastomosis with intestinal tracts can be synchronously performed.

The upper portion of the separation protective film 300 is wound to form a curled portion 310, and the curled portion 310 is received in the annular groove 110. The curled portion 310 can enable the annular groove 110 to accommodate more isolation protection films 300, and can enable the upper portion of the isolation protection films 300 to be stably placed in the annular groove 110 after being wound.

A top cover 400 is arranged at the top of the nail propping seat 100, and the outer edge of the top cover 400 covers the curled portion 310. This configuration provides a barrier to the crimp 310 for the cap 400 to prevent the crimp 310 from being easily removed from the annular groove 110.

The bottom of the nail propping seat 100 is in an annular structure, and the lower part of the isolation protection film 300 is fixed on the inner wall 120 of the bottom of the nail propping seat 100. This structure enables the lower portion of the separation protection film 300 to be stably fixed to the nail holder 100.

The separation protective film 300 is made of a bio-based degradable material so that the separation protective film 300 can be degraded in vivo. The barrier protective film 300 is made of a material with a healing factor to promote healing of an anastomotic wound.
