Abstract
Description
Technical Field
[0001] The utility model relates to a transanal intestinal anastomotic inflatable leak detection device, belonging to the technical field of medical products. Background Art
[0002] In rectal surgery, a circular tubular stapler is usually used through the anus to perform proximal and distal intestinal anastomosis. After the anastomosis, the quality of the anastomosis needs to be tested, that is, the integrity of the anastomosis and whether there is anastomotic leakage. For the integrity of the anastomosis, the anastomotic loop intestinal tube on the stapler is usually checked, and for the presence of anastomotic leakage, it is difficult to judge with the naked eye because such anastomosis is located in a small pelvic space.
[0003] At present, the general practice is to use gas leak detection. The specific operation is: first use an intestinal clamp to clamp the proximal intestinal tube of the anastomosis, then perfuse normal saline into the pelvic cavity until the anastomosis is submerged, and then use an anal irrigator or syringe to inject gas into the intestinal cavity from the anus, and observe whether there is an anastomotic leak by observing whether there is air bubble overflow from the anastomosis in the abdominal cavity. If there is gas overflow, it indicates that there is an anastomotic leak, and remedial measures such as reinforcement suture are required. However, when patients undergo rectal surgery, due to anesthesia and anal dilation before intestinal anastomosis, the anal sphincter is usually in a relaxed state. Therefore, when injecting gas, gas usually overflows from around the anal irrigator or syringe, resulting in poor intestinal cavity inflation and insufficient intestinal cavity expansion, which affects the judgment of the anastomotic quality. Utility Model Content
[0004] The technical problem to be solved by the utility model is to solve the problem that the leakage of traditional anal douches or syringes leads to poor leakage detection effect.
[0005] In order to solve the above-mentioned technical problems, the technical solution of the utility model is to provide a transanal intestinal anastomosis inflation leak detection device, which is characterized in that it includes a circular tube body, an inflatable balloon and a connecting tube. The circular tube body is a hollow tube structure. A cavity is provided in the circular tube body. The inflatable balloon is connected to the proximal end of the circular tube body through the connecting tube and is connected to the cavity. An air outlet connected to the cavity is provided at the distal end of the circular tube body. A first one-way valve that allows gas to enter the circular tube body only from the inflatable balloon is provided in the channel formed between the circular tube body and the inflatable balloon. A second one-way valve that allows gas to enter the inflatable balloon only from the outside is provided on the inflatable balloon. An annular silicone pad is also provided on the outer wall of the circular tube body. The center of the annular silicone pad is sleeved on the circular tube body and is sealingly connected to the outer wall of the circular tube body.
[0006] Preferably, an air inlet hole is provided at the position where the proximal end of the circular tube is connected to the connecting tube, and the connecting tube is connected to the cavity through the air inlet hole.
[0007] Preferably, a handle is connected to the outer side of the proximal end of the circular tube.
[0008] Preferably, the annular silicone pad is arranged on the outer wall of the circular tube body close to the proximal end.
[0009] Preferably, a fixing groove is provided on the outer wall of the circular tube body, and an annular silicone gasket is arranged in the fixing groove and is sealed and connected to the fixing groove.
[0010] Preferably, the first one-way valve is arranged at the air outlet of the inflatable balloon, or at the air inlet of the circular tube, or in the connecting tube between the inflatable balloon and the air inlet hole.
[0011] Preferably, the annular silicone pad is a double-layer structure, a layer close to the proximal end is a hard silicone layer, and a layer close to the patient's anus is a soft silicone layer.
[0012] Preferably, the annular silicone pad is a bowl-shaped structure, with a concave surface at the proximal end and a convex surface at the distal end.
[0013] Preferably, a plurality of air outlet holes are arranged at the far end of the circular tube.
[0014] Preferably, the distal end of the circular tube is an arc-shaped structure; and a plurality of air outlet holes are evenly distributed on the arc surface of the circular tube.
[0015] The utility model is a simple transanal intestinal anastomosis inflation leak detection device, which is used to judge the anastomotic condition of the intestinal anastomosis after rectal resection and intestinal anastomosis, that is, whether there is an incomplete anastomosis, anastomotic leakage, etc., so as to improve the leak detection effect. It solves the problem that the traditional anal irrigator or syringe leaks and causes poor leak detection effect.
[0016] The utility model improves the leakage detection efficiency through the following two points: when inflating, a round hard silicone pad is pressed against the anus to avoid leakage; the inflated balloon is connected to the one-way air inlet hole at the proximal end of the round tube body through a connecting tube to increase the inflation efficiency.

[0019] In order to make the present invention more obvious and easy to understand, preferred embodiments are described in detail as follows in conjunction with the accompanying drawings.
[0020] The utility model provides a transanal intestinal anastomosis inflation leakage detection device, such as Figure 1 , Figure 2As shown, it includes a circular tube body 6 and an inflatable balloon 1 and a connecting tube 2. The circular tube body 6 is a hollow tube structure, in which a cavity 8 is provided. A plurality of air outlets 7 are provided at the far end of the circular tube body 6, and all the air outlets 7 are connected to the cavity 8. A one-way air inlet 4 and a handle 10 are provided at the proximal end of the circular tube body 6, and the air inlet 4 is connected to the cavity 8, wherein the circular tube body 6 and the handle 10 are an integral structure, and the air inlet 4 is connected to the inflatable balloon 1 through the connecting tube 2. There is also an annular silicone pad 5 on the outer side of the proximal end of the circular tube body 6, which is used to press against the anus during inflation to prevent air leakage. A fixed card slot 9 is provided on the outer wall of the circular tube body 6, and the fixed card slot 9 is located between the air inlet 4 and the air outlet 7. The center hole of the annular silicone pad 5 is sleeved in the fixed card slot 9, and it is sealed and connected to the fixed card slot 9. A first one-way valve 3 is provided at the air outlet of the inflatable balloon 1, or in the air inlet 4, or in the connecting tube 2 between the inflatable balloon 1 and the air inlet 4, which only allows gas to enter the circular tube body 6 from the inflatable balloon 1. A second one-way valve 11 is provided on the inflatable balloon 1, which only allows external gas to enter the inflatable balloon 1.
[0021] In this embodiment, the annular silicone pad 5 is a double-layer structure, wherein the layer near the proximal end is a hard silicone layer, and the layer near the patient's anus is a soft silicone layer, which can ensure that the annular silicone pad 5 can apply a certain pressure to the patient's anus, and can also ensure that the annular silicone pad 5 is in flexible contact with the patient's skin, and enhance the sealing effect (the soft silicone layer has a certain elastic function, and the sealing effect is achieved by tightening in the fixed card slot 9). The annular silicone pad 5 is a bowl-shaped structure, with a concave surface at the proximal end and a convex surface at the distal end. The distal end of the circular tube body 6 is an arc-shaped structure, which is convenient for inserting into the patient's anus, while preventing damage to the patient's intestinal tract and anastomosis.
[0022] The use process of the utility model is as follows:
[0023] When in use, first connect the inflatable balloon 1 to the one-way air inlet (including the first one-way valve 3 and the air inlet 4) at the proximal end of the circular tube 6 through the connecting tube 2, then apply lubricant to the outside of the circular tube 6, insert it into the intestinal cavity through the anus, and force the annular silicone pad 5 close to the anus. The medical staff squeezes the inflatable balloon 1 to inject gas into the circular tube 6, and the gas enters the intestinal cavity through the air outlet 7 at the distal end of the circular tube 6. After the leak detection is completed, the circular tube 6 can be directly withdrawn.
[0024] During open surgery, one medical staff squeezes the inflated balloon 1 and ensures that the annular silicone pad 5 is close to the anus; another medical staff observes the inflation effect of the intestinal tube and stops inflation after the intestinal tube is fully expanded.
[0025] When performing robotic surgery or laparoscopic surgery, it can be achieved by a medical staff, that is, the medical staff squeezes the inflatable balloon 1, ensures that the annular silicone pad 5 is close to the anus, observes the intestinal inflation result displayed on the computer screen, and stops inflation after the intestinal tube is fully expanded.
