Abstract
Description
Technical Field
[0001] This utility model relates to surgical instruments for enteroscopy, specifically to an anti-contamination device for intraoperative enteroscopy. Background Technology
[0002] For patients suspected of small bowel bleeding but whose bleeding point cannot be identified by DSA examination, exploratory laparotomy typically involves incising the intestinal wall in the middle of the small intestine and inserting a gastroscope through the incision to conduct a comprehensive examination of the small intestine, accurately locating the bleeding site and guiding subsequent treatment. Traditionally, the small intestine is directly suspended with sutures to fix and expose the incised area. However, this method has limitations. Due to the relatively large gap between the small bowel incision and the endoscope, complete closure is difficult, allowing small bowel contents (including intestinal fluid and potential bacteria) to flow into the abdominal cavity, increasing the risk of postoperative abdominal infection. Furthermore, the entry of small bowel contents into the abdominal cavity may induce an inflammatory response, increasing the risk of intestinal adhesions and obstruction, further affecting the patient's postoperative recovery. Therefore, optimizing the small bowel fixation method to reduce intestinal fluid leakage, lower the risk of infection, and facilitate endoscopic examination is a crucial issue in clinical practice. Utility Model Content
[0003] To reduce the risk of intestinal fluid flowing into the peritoneal cavity during small bowel endoscopy and subsequently causing postoperative abdominal infection, this application innovatively designs a novel anti-contamination device based on clinical practice and observation, drawing on the advantages of existing anti-contamination devices for small bowel endoscopy both domestically and internationally. This device effectively reduces the occurrence of postoperative abdominal infection and improves surgical safety. The specific scheme is as follows:
[0004] An anti-contamination device for intraoperative small enteroscopy, the device comprising a detachably connected first connecting part and a second connecting part;
[0005] The first connecting part is composed of a hard rubber ring coaxially fixed to one end face of the first threaded tube;
[0006] The second connecting part includes a balloon body. Both ends of the balloon body are fixedly connected to an endoscope insertion tube and a second threaded tube connected to the inner cavity of the balloon body. The axes of the endoscope insertion tube and the second threaded tube coincide with the central axis of the balloon body. The endoscope insertion tube is a hollow tube with a smooth inner wall. The second threaded tube is detachably connected to the first threaded tube by threads. A drainage tube is connected to one side of the balloon body. The drainage tube is used to connect an external drainage bag.
[0007] The first connecting part is installed in the middle section of the small intestine and the first threaded tube is exposed through the small intestine incision and threadedly connected to the second threaded tube. The diameter of the rigid rubber ring is larger than that of the small intestine incision and is located inside the small intestine.
[0008] Furthermore, the first threaded tube is an externally threaded tube, and the second threaded tube is an internally threaded tube.
[0009] Furthermore, the inner diameter of the first threaded tube is 15mm, the height is 10mm, and the wall thickness is 1mm;
[0010] The diameter of the hard rubber ring is 20 mm.
[0011] Furthermore, the major axis diameter and minor axis diameter of the balloon body are 50 mm and 40 mm, respectively.
[0012] Furthermore, the inner diameter of the endoscope insertion tube is 12mm and the height is 10mm;
[0013] The second threaded tube has an inner diameter of 17mm, a height of 15mm, and a wall thickness of 2mm.
[0014] Furthermore, the inner wall of the endoscope insertion tube is provided with a one-way valve.
[0015] Furthermore, the first threaded tube, the endoscope insertion tube, the second threaded tube, and the drainage tube are all made of rigid plastic tubes, and the main body of the balloon is a rubber balloon.
[0016] The device provided by this invention can completely fix the incision site of the small intestine wall, effectively preventing intestinal fluid from flowing into the abdominal cavity, thereby reducing the risk of abdominal infection; at the same time, it can introduce the outflowing intestinal fluid into a drainage bag, achieving the effect of decompression of the small intestine while completing the endoscopic examination.

[0022] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0023] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.
[0024] Reference Figure 1-4 As shown, this utility model provides an anti-contamination device for intraoperative enteroscopy, which consists of a detachably connected first connecting part 10 and a second connecting part 20.
[0025] First connecting part 10
[0026] The first connecting part 10 is composed of a hard rubber ring 12 coaxially fixed to one end face of the first threaded tube 11.
[0027] Second connecting part 20
[0028] The second connecting part 20 includes a balloon body 21. Both ends of the balloon body 21 are fixedly connected to an endoscope insertion tube 22 and a second threaded tube 23 connected to the inner cavity of the balloon body 21. The axes of the endoscope insertion tube 22 and the second threaded tube 23 coincide with the central axis of the balloon body 21. The endoscope insertion tube 22 is a hollow tube with a smooth inner wall. The second threaded tube 23 is detachably connected to the first threaded tube 11 by threads. A drainage tube 24 is connected to one side of the balloon body 21. When draining intestinal fluid, the drainage tube 24 is connected to the drainage bag.
[0029] The first connecting part 10 is installed in the middle section of the small intestine, and the first threaded tube 11 is exposed through the small intestine incision and threadedly connected to the second threaded tube 23. The diameter of the rigid rubber ring 12 is larger than that of the small intestine incision and is located inside the small intestine.
[0030] In an optional embodiment, the first threaded tube 11 is an externally threaded tube, and the second threaded tube 23 is an internally threaded tube.
[0031] In an optional embodiment, the first threaded tube 11 has an inner diameter of 15 mm, a height of 10 mm, and a wall thickness of 1 mm; the hard rubber ring 12 has a diameter of 20 mm.
[0032] In an optional embodiment, the major axis diameter and minor axis diameter of the balloon body 21 are 50 mm and 40 mm, respectively. The inner diameter of the endoscope insertion tube 22 is 12 mm and the height is 10 mm; the inner diameter of the second threaded tube 23 is 17 mm, the height is 15 mm, and the wall thickness is 2 mm.
[0033] In an optional embodiment, the first threaded tube 11, the endoscope insertion tube 22, the second threaded tube 23, and the drainage tube 24 are all rigid plastic tubes, and the balloon body 21 is a rubber balloon.
[0034] Furthermore, the inner wall of the endoscope insertion tube 22 is equipped with a one-way valve. This one-way valve prevents intestinal fluid from flowing out of the endoscope insertion tube 22, ensuring that the intestinal fluid can only flow out through the drainage tube 24. At the same time, the one-way valve can be opened and the endoscope can be advanced during insertion.
[0035] The method of using this application during surgery is as follows:
[0036] (1) First, make a purse-string suture at the middle 30 of the small intestine and then make a longitudinal incision in the small intestine.
[0037] (2) Insert the first connecting part 10, tighten the purse and tie it in the first threaded tube 11, so that the first threaded tube 11 is exposed through the small intestine incision, and the hard rubber ring 12 is located on the inner wall of the small intestine.
[0038] (3) Tighten and fix the second threaded tube 23 of the second connecting part 20 to the first threaded tube 11, as follows: Figure 4 As shown, because the diameter of the rigid rubber ring 12 is larger than the incision in the small intestine, the device is connected to the small intestine and prevented from dislodging. Figure 4 As shown.
[0039] (4) Insert the small bowel endoscope into the endoscope insertion tube 22 of the second connecting part 20, and then continue to advance the small bowel endoscope so that it passes through the balloon body 21, the second threaded tube 23, and the first threaded tube 11 to enter the small intestine for examination. A drainage bag is connected to the drainage tube 24 to further collect any leaked intestinal fluid, ensuring the cleanliness of the surgical area and reducing the risk of postoperative infection.
[0040] (5) After the examination is completed, remove the drainage bag and take out the small bowel endoscope, open the small bowel incision, remove the first connecting part 10 and the second connecting part 20, and suture to close the small bowel incision.
[0041] In summary, the advantages of this utility model are as follows:
[0042] 1) Effectively reduce the risk of infection
[0043] The rigid rubber ring and threaded connection structure achieves a tight seal of the small intestine incision, significantly reducing the possibility of intestinal fluid and bacteria flowing into the abdominal cavity; the drainage tube is connected to an external drainage bag to actively collect exudate, providing double protection for the cleanliness of the surgical area and reducing the risk of postoperative abdominal infection and complications (such as intestinal adhesions and intestinal obstruction).
[0044] 2) Structural optimization and ease of operation
[0045] Detachable design: The first connecting part (including the external threaded tube and rubber ring) and the second connecting part (including the balloon and endoscope tube) are quickly connected by threads, which facilitates installation and removal during the operation.
[0046] Endoscope insertion tube design: The smooth inner wall of the hollow tube facilitates smooth insertion of the endoscope and improves examination efficiency.
[0047] 3) Improved clinical applicability
[0048] Simplified procedure: The first connection is fixed by purse-string suture, eliminating the need for complicated suspension steps and shortening the operation time.
[0049] Compatibility and scalability: Supports connection to various endoscopic devices, suitable for different clinical scenarios, such as small bowel bleeding localization and postoperative examination.
[0050] This invention solves the problems of inadequate incision closure and high infection risk in traditional enteroscopy, while also being convenient, safe, and clinically practical, significantly improving the success rate of surgery and the quality of postoperative recovery for patients.
