Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to a closed colon flushing and suction sleeve used in surgery. Background Art
[0002] Colonic obstruction is a common abdominal emergency in clinical practice, with a high incidence rate and severe condition. In addition, due to the structural characteristics of the colon (the right colon is wide and conducive to the storage of fecal water, the left colon and sigmoid colon are relatively slender, and the feces in the left colon area are more formed into blocks, the splenic flexure of the colon is tortuous at an acute angle, and there is a one-way ileocecal valve at the tail end of the terminal ileum), the descending colon and sigmoid colon are prone to obstruction. After colonic obstruction, the proximal end of the obstruction forms a closed loop intestinal obstruction, so a large amount of formed feces, food residues, intestinal fluid and gas are retained in the proximal intestinal cavity of the obstruction.
[0003] When performing abdominal surgery on colon obstruction, it is necessary to fully decompress, flush and aspirate most of the contents of the proximal intestine to reduce the pressure in the intestine and make room for intestinal resection and stoma. Decompression and flushing of intestinal contents are crucial for postoperative recovery. During surgery, if the colon cavity is directly opened for decompression and flushing, the contents may easily flow out and contaminate the abdominal cavity and surgical field if not properly controlled, causing severe abdominal cavity infection and incision infection after surgery. In addition, the feces in the colon contents are often formed, the residues are coarse, and the colon is tortuous (the largest folded part is often located in the splenic flexure of the colon). Ordinary suction lines are easily blocked by formed feces and residues, and cannot be effectively attracted and flushed. In addition, shorter lines cannot flush the colon contents on the right side and in the transverse colon. For this reason, the utility model provides a closed colon flushing suction cannula used in surgery. Utility Model Content
[0004] The utility model aims to provide a closed colon irrigation and suction sleeve used in surgery to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A closed colon irrigation suction sleeve used in surgery, comprising a suction sleeve and a film seal, wherein the film seal is sealed and connected to one end of the suction sleeve, and the other end of the suction sleeve is a suction hole for inserting into the intestine, and a plurality of side holes are opened near the outer periphery of the suction hole; an inner core tube is arranged inside the suction sleeve, and one end of the inner core tube is a cone with the head end facing the suction hole, and the blunt end of the cone is slidably connected to the inner wall of the suction sleeve, and feces enters the suction sleeve through the suction hole or the side hole through the sliding of the inner core tube, and the other end of the inner core tube extends to the inside of the film seal, so as to prevent feces entering the suction sleeve from overflowing from one end of the suction sleeve to cause pollution;
[0007] A pair of negative pressure interfaces are extended from the outer periphery of the suction sleeve near the film cover for connecting the negative pressure tube to increase the suction force in the suction tube.
[0008] Preferably, an auxiliary water pipe is fixedly connected to the outer periphery of the suction sleeve, one end of the auxiliary water pipe extends to the suction hole for water outlet, and the other end is detached from the outer periphery of the suction sleeve, and an infusion interface is provided as a water inlet.
[0009] Preferably, the auxiliary water pipe and the suction sleeve are fixedly connected with an anti-leakage part at their outer peripheries, and the outer wall of the anti-leakage part is provided with a plurality of axially arranged anti-leakage grooves for binding and suturing with the colon incision to ensure the airtightness of the incision.
[0010] Preferably, the length of the film envelope is slightly greater than the length of the inner core tube.
[0011] Preferably, a round hole valve is installed on the inner wall at the tail end of the suction sleeve.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model has a simple structure and is easy to operate. The auxiliary water pipe, the inner core pipe and the film cover are integrated inside or outside the suction sleeve to form a combined sleeve with flushing and decompression function, wherein the film cover is sealed with the end of the suction sleeve, which effectively avoids the risk of feces overflowing from the tail end of the suction sleeve and contaminating the surgical field and the abdominal cavity when feces is sucked into the suction sleeve, which is safer and reduces surgical risks.
[0014] The tapered end of the inner core tube is pushed to the head end, which is convenient for guiding through the curved part of the colon to reach the transverse colon, so as to fully decompress the colon.
[0015] The suction hole and side hole are used to attract feces, and an inner core tube is provided to push the blocked suction sleeve. With the cooperation of the auxiliary water pipe, the feces are softened and diluted, and it is not easy for the feces to block the suction sleeve. The double negative pressure interface is used alternately with the inner core tube to avoid the blockage of the suction sleeve, making the decompression of the intestine smoother and more effective;
[0016] With a wide range of applications, the suction cannula can be designed with different diameters and sizes to adapt to different intestinal locations, and can even be used for small intestinal obstruction and some severe abdominal abscesses. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] A round hole valve 6 is installed on the inner wall at the tail end of the suction sleeve 1 to limit the conical end of the inner core tube 2 and prevent the formed feces from entering the film envelope 3.
[0027] An auxiliary water pipe 4 is fixedly connected to the outer periphery of the suction sleeve 1. One end of the auxiliary water pipe 4 extends to the suction hole 11 for water outlet, and the other end is separated from the outer periphery of the suction sleeve 1. An infusion interface is provided as a water inlet 41 for water delivery.
[0028] The auxiliary water pipe 4 and the outer periphery of the suction sleeve 1 are fixedly connected with an anti-leakage part 5, and the outer wall of the anti-leakage part 5 is provided with a plurality of axially arranged anti-leakage grooves for suturing the colon incision to prevent the infiltration of pollutants at the incision. The end of the suction sleeve 1 and the end of the auxiliary water pipe 4 located at the end of the suction sleeve 1 are rounded to avoid scratching the inner wall of the intestinal cavity (see Figure 5 ).
[0029] Working principle: The blunt end of the inner core tube 2 protrudes from the head end of the suction sleeve 2, forming a blunt and rounded structure at the head end of the suction sleeve 1 as the initial state, so as to facilitate the smooth guidance or insertion of the suction sleeve 1 in the colon cavity (see Figure 5 ), the surgeon opens a small hole through the upper end of the sigmoid colon, inserts it into the colon cavity through the incision and gradually guides it upward across the splenic flexure of the colon. The purse-string suture of the intestinal wall puncture is fixed to the outer wall of the anti-leakage part 5, one of the negative pressure interfaces 13 is connected to the negative pressure tube, and the other negative pressure interface 13 is reserved.
