Embodiment 1

[0045] The present invention comprises a decompression tube 1, a puncture cone 2 and an inner casing 3;

[0046] The pipe wall in the middle part of the decompression pipe 1 is a folded and fixed part. The pipe wall of the folded and fixed part is surrounded by a plurality of cutting lines 1-1 extending along the length of the pipe wall. The pipe of the folded and fixed part The wall is also provided with three front circular creases 1-2, middle circular creases 1-3 and rear circular creases 1-4 which surround the pipe wall and are respectively located at the front end, middle part and rear end of each cutting line 1-1;

[0047] The inner sleeve 3 is sleeved in the lumen of the decompression tube 1 and can move back and forth relative to the decompression tube 1, and the rear wall of the decompression tube 1 and the inner sleeve 3 is provided for relative movement of the two. The locking mechanism for locking or unlocking the position; the locking mechanism is composed of a th...

Embodiment 2

[0071] This embodiment is a further improvement of embodiment 1 on the basis of embodiment 1, and its difference with embodiment 1 is:

[0072] The locking mechanism consists of a positioning groove 3-3 arranged on the wall at the rear end of the inner sleeve 3 and an elastic positioning device 1-3 installed on the wall at the rear end of the decompression tube 1 and capable of telescopic movement perpendicular to the wall. 7 composition.

[0073] There are at least two positioning grooves 3-3 on the pipe wall at the rear end of the inner sleeve 3, which are used to lock the starting and ending positions of the inner sleeve 3 moving back and forth in the decompression tube 1 respectively.

Abstract

The invention relates to the field of medical instruments, in particular to an extension-type gastric puncture flushing and decompression device. The extension-type gastric puncture flushing and decompression device comprises a decompression pipe, a puncture cone and an inner casing pipe, wherein part of the pipe wall of the middle part of the decompression pipe is a foldable fixing portion; multiple cutting-off lines are arranged around the pipe wall of the foldable fixing portion; the pipe wall of the foldable fixing portion is further provided with a front annular fold, a middle annular fold and a rear annular fold around the pipe wall; the inner casing pipe is sleeved with a pipe cavity of the decompression pipe; a locking mechanism is arranged between the decompression pipe and the pipe wall of the rear end of the inner casing pipe; a first outwards protruding limiting mechanism is arranged on the outer side of the pipe wall of the front end of the inner casing pipe; the puncture cone is arranged inside the pipe cavity of the inner casing pipe in a penetrating mode; the front end of the puncture cone is a sharp cone portion; a second limiting mechanism is arranged between the outer wall of the puncture cone and the inner side of the pipe wall of the inner casing pipe; a handle bar is arranged at the rear end of the puncture cone; a third limiting mechanism is arranged on the outer side of the pipe wall of the decompression pipe. The extension-type gastric puncture flushing and decompression device is used for flushing and decompressing the stomach, is easy and convenient to operate and can prevent operative infection.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a sleeve type gastric puncture flushing decompression device. Background technique [0002] Before total gastrectomy or partial gastrectomy, a large amount of food residues usually accumulate in the stomach. In order to prevent the contents of the stomach from spilling into the abdominal cavity during gastrectomy, maintain the cleanliness of the surgical area, and avoid secondary pollution, it is necessary to The stomach is flushed and decompressed to clean up its contents, so as to facilitate further operations and reduce the occurrence of complications. [0003] The existing practice is that medical personnel open an opening in the stomach in advance through surgery, and then perform manual flushing. This is a complicated operation, and it is also easy to contaminate the abdominal cavity, which greatly increases the chance of surgical infection for patients. Contents of the inv...
