Description

Technical Field

[0001] The invention relates to the technical field of rectal irrigators, in particular to a rectal irrigator used during rectal anastomosis surgery. Background Art

[0002] Currently, during rectal and sigmoid colon cancer surgeries, digestive tract reconstruction is required after resection of the diseased intestinal tract. The most common method for rectal anastomosis is to insert a circular stapler through the anus to complete the intestinal anastomosis. However, sufficient and effective rectal irrigation before anastomosis is very important to reduce the occurrence of anastomotic fistulas. In recent years, especially with the widespread implementation of laparoscopic radical resection of rectal cancer in hospitals at all levels, the method commonly used by gastrointestinal surgeons is: first, use a cutting stapler to separate the rectum in the abdominal cavity, and then perform rectal irrigation through the anus. At this time, the remaining rectum is relatively short, generally within 15 centimeters from the anal edge. Therefore, rectal irrigation needs to ensure two points: first, it needs to quickly and effectively flush out any residual feces in the rectum, especially when the intestinal preparation is poor; second, it must not affect the rectal stump that is completely closed by the stapler, and in particular, it must not puncture the rectal stump.

[0003] According to Chinese patent publication number CN208756659U, a rectal irrigator used during rectal anastomosis surgery is disclosed, including a syringe, a piston rod, a piston, an injection port, a rubber ring, an irrigation tube, an inflation tube, a sealing ring, a hand-pumped air pump, an exhaust port, a rubber stopper, a side hole, an air bag, a connecting tube, a threaded protrusion and a hydrophilic coating.

[0004] Currently, the existing rectal irrigators used in rectal anastomosis surgery cannot continuously clean fixed points during use, which easily leads to poor cleaning effects. Therefore, improvements are made to address the above problems. Summary of the Invention

[0005] In view of the problems in the prior art, the present invention provides a rectal irrigator used in rectal anastomosis surgery.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a rectal irrigator used in rectal anastomosis surgery, comprising a first cleaning structure and a second cleaning structure, wherein the second cleaning structure is fixedly provided on the first cleaning structure;

[0007] The first cleaning structure is used for cleaning treatment, the injection component is connected to the spray pipe through the connecting pipe and the conduit, and the auxiliary injection mechanism is connected to the injection pipe through the docking pipe for liquid replenishment treatment;

At the same time, the cleaning liquid is stored in the auxiliary injection mechanism. By pushing the guide rod, the liquid in the connecting tube is guided to the docking tube through the one-way valve tube, thereby providing a surplus of cleaning liquid in the injection tube.

[0020] Second, the present invention can perform cleaning work at specific positions through the structural setting of the second cleaning structure. At this time, the inflation tube is pressed, so that the gas is transmitted to the second connecting air tube through the docking connecting seat, and then acts on the docking connecting air tube through the first connecting air tube.
