Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a novel external fixation anal decompression device. Background Technology

[0002] Currently, various intestinal diseases, such as colorectal cancer and benign lesions, are mainly treated surgically. However, all surgical methods face the same problem during the postoperative recovery phase: relieving pressure and releasing gas from the anus. Poorly managed issues can increase the recurrence rate and cause greater difficulties for patients.

[0003] Clinically, anal decompression tubes are commonly used for anal decompression. However, traditional decompression tubes have the following problems: 1. The materials used for decompression tubes are generally plastic, rubber, or latex with a certain degree of hardness to facilitate insertion. However, if the material is too hard, it may cause intestinal fistula. If the hardness of the material is reduced, it is not easy to insert. 2. If perianal sutures are used, infection is likely to occur, and the operation is difficult. 3. There is no fixing device, so it is easy to slip out. 4. The internal tubing of the decompression tube is complex, which is not conducive to the discharge of foreign objects and cleaning and disinfection.

[0004] Chinese patent CN201120363122.9 discloses an anal decompression device with a relatively complex structure. Its outer sleeve 1 has multiple tubes inside, including a first channel 22, a second channel 32, a flushing tube 8, and an inner sleeve 7, which is not conducive to the discharge and cleaning of foreign objects. It uses two sacs 2 and 3 for fixation, which has a large fixation area and causes strong discomfort. It does not solve the problem of the softness or hardness of the anal tube, and can only use an outer sleeve made of a relatively hard material. Improper use and operation can cause intestinal fistula. If a soft material is used, it is not easy to insert.

[0005] Chinese patent CN 208641381 U also discloses an anal decompression device, but it also uses a sac to fix it inside the patient, which greatly increases the patient's discomfort. In addition, the anal decompression device does not have a guide structure and mainly relies on manual insertion. Therefore, its material needs to be relatively hard, which can easily lead to complications. Therefore, there is an urgent need in the field for an anal decompression device that can be easily fixed, does not make the patient feel uncomfortable, and can also be inserted by using a colonoscope to drive the guide structure.

[0016] In a preferred embodiment, the negative pressure device is further equipped with a collection bag for collecting the liquid discharged from the pressure-reducing tube.

[0017] In a preferred embodiment, the length of the pressure-reducing tube is 40-100 cm.

[0018] In a preferred embodiment, the pressure-reducing pipe is provided with a connector at the curvature, which divides the pressure-reducing pipe into a straight pipe section and a curved pipe section and connects the straight pipe section and the curved pipe section.

[0019] In a preferred embodiment, the straight pipe is configured with multiple pipe sizes to meet different pressure reduction requirements.

[0020] In a preferred embodiment, the external fixation device is selected from the group consisting of: Velcro and snap fasteners.

[0021] The main advantages of this utility model include:

[0022] 1) By placing the fixation device outside the body, this utility model greatly reduces the patient's discomfort and makes it easier to use.

[0023] 2) By configuring the pressure-reducing tube into various detachable specifications, this utility model ensures that it can perfectly adapt to any lesion.

[0024] 3) This utility model is equipped with a traction device on the decompression tube. During surgery, it can be held by a colonoscope in combination with biopsy forceps or foreign body forceps, thereby guiding the insertion of the decompression tube under direct colonoscopic vision. This allows the utility model to use softer materials and eliminates concerns about insertion problems.

[0025] The specification of this utility model contains numerous technical features distributed across various technical solutions. Listing all possible combinations of these features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described utility model, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which should be considered as described in this specification), unless such a combination of technical features is technically infeasible. For example, one example discloses feature A+B+C, and another example discloses feature A+B+D+E. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; they cannot be used simultaneously. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Example

[0032] The external fixation anal decompression device described in this embodiment is as follows: Figure 1 As shown, the external fixation anal decompression device includes: an external fixation device 1, a negative pressure device 2, a decompression tube 9, and a traction device, wherein:

[0033] The pressure reducing tube 9 is as follows Figure 1 As shown, it is an L-shaped tubular structure with an arc, including a straight pipe 3 and a curved pipe 8. One end of the straight pipe is the insertion end 5, and the other end of the curved pipe is the pressure reducing end 7. The pressure reducing end 7 is configured to be fully open and is connected to the negative pressure device 2. The top of the insertion end 5 is closed, and the pressure reducing pipe 9 has an opening 4 on the pipe wall at the port of the insertion end 5. Optionally, in one embodiment, the number of openings is not less than 4, and they are evenly distributed vertically from the port of the insertion end to a distance of 8-12 cm from the port of the insertion end, so as to better absorb wastewater.

[0034] Optionally, in one embodiment, the negative pressure device 2 is further provided with a negative pressure pipe 10 and connected to the pressure reducing end of the pressure reducing pipe through the negative pressure pipe 10. The length of the negative pressure pipe is 20-50cm.

[0035] Optionally, in one embodiment, the overall length of the pressure reducing tube 9 is 40-100cm, and the diameter is 4-10cm.

[0036] Optionally, in one embodiment, the straight tube body 3 and the bent tube body 8 of the pressure reducing pipe 9 are connected by integral molding.

[0037] The traction device is located at the insertion end of the decompression tube and is used to guide the decompression tube in conjunction with a colonoscope during surgery.

[0038] Optionally, in one embodiment, the traction device is as follows: Figure 1 The imaging ring 6 shown is fixed to the insertion end 5 of the decompression tube 9 for easy dragging. The imaging ring 6 also plays a positioning role in imaging (X-ray or CT) within the patient's body, allowing for a more intuitive understanding of the specific position of the decompression tube and whether there are any misalignments.

[0039] Optionally, in one embodiment, the traction device is configured as a guide wire that passes through the pressure-reducing tube through an opening at the tip of the insertion end and guides the insertion process of the pressure-reducing tube by clamping the guide wire.

[0040] The external fixation device 1 is disposed on the curved body 8 of the decompression tube and is configured to be detachably fixed to the patient's thigh. Optionally, in one embodiment, the external fixation device is a buckle or Velcro.

[0041] Optionally, in one embodiment, the negative pressure device 2 is further equipped with a collection bag for collecting the liquid discharged from the pressure reducing pipe 9.

[0042] Optionally, in one embodiment, the negative pressure device 2 is as follows: Figure 1 As shown, negative pressure can be manually generated by squeezing, allowing patients to control it themselves.

[0043] Optionally, in one embodiment, the pressure-reducing pipe 9 is configured to be detachable and replaceable. Specifically, the pressure-reducing pipe 9 is provided with a connector between the straight pipe body 3 and the bent pipe body 8. Furthermore, the straight pipe body 3 is provided with multiple specifications of pipe bodies to meet different pressure reduction requirements. Specifically, in one embodiment, the external segment includes: a 50cm long soft decompression tube, an 80cm long soft decompression tube, a 50cm long rigid decompression tube, and an 80cm long rigid decompression tube. This arrangement is designed so that different symptoms require different levels of rigidity in the decompression tube. For simple decompression, a soft tube can be used to minimize the possibility of complications. For symptoms such as intestinal volvulus, the decompression tube not only reduces pressure but also corrects the torsion site; using a soft tube would affect this correction. Furthermore, for most symptoms, the decompression tube only needs to reach or exceed certain symptom sites for optimal results. However, existing decompression tubes are of uniform length. When shorter lengths are required, excessive external exposure affects the fixation effect. Therefore, two different lengths of decompression tubes are provided to make it suitable for almost all symptom locations.
