Description

Technical Field

[0001] The utility model belongs to the technical field of hernia repair, and in particular relates to a parastomal hernia repair patch. Background Art

[0002] Parastomal hernia is a special type of incisional hernia, which only occurs in patients with intestinal or urinary stomas in the abdominal wall. It is also one of the common long-term complications of indwelling stomas after intestinal and bladder surgery, affecting the quality of life of patients, with an overall incidence rate of 30-50%. The cause of parastomal hernia is that the fascia (abdominal wall muscle sheath) at the stoma site fails to close, causing the abdominal viscera to protrude through the defect to the abdominal wall, which manifests as a bulge in the skin around the stoma or a visible mass, often accompanied by discomfort (abdominal distension and pain, pulling pain, difficulty in defecation, etc.). In severe cases, the herniated intestine is compressed, ischemic, or even necrotic, which can progress to a life-threatening emergency. Generally speaking, the clinical manifestations of parastomal hernia in the early stage of formation are similar to those of incisional hernia, mostly reducible abdominal wall masses or bulges, which are obvious when standing or exerting abdominal force, and slowly shrink or disappear completely when lying flat. As the disease progresses, the size of the parastomal hernia will increase, accompanied by various discomforts and dysfunction of the stoma adjacent to the hernia.

[0003] Parastomal hernia is a special type of incisional hernia, and its treatment principles are the same as those of incisional hernia. Wearing a belly band and drug treatment can only maintain or control the progression of the hernia and improve the discomfort symptoms associated with the hernia, but it is absolutely impossible to cure the disease. At present, the recommended surgery for parastomal hernia is to use a minimally invasive method, repairing the defect of the parastomal hernia from the abdominal cavity through several small holes, and then placing a patch for reinforcement; according to the relationship between the patch and the stoma intestinal tube after placement, it can be divided into two procedures: Keyhole and Sugarbaker. The Keyhole procedure refers to the use of a special patch with a sleeve around the stoma intestinal tube, such as Figure 1 As shown in the figure, the patch A1 is cut and then the stoma intestinal tube A2 is passed through; the Sugarbaker procedure refers to covering the stoma intestinal tube with a patch so that the stoma intestinal tube is close to the lateral abdominal wall, such as Figure 2 As shown, the patch A1 presses the stoma intestinal tube A2 toward the lateral abdominal wall, covering the intestinal tube together with the hernia defect. Figure 2 The method shown is the one that is currently more commonly used in clinical practice.

[0004] However, since the patches currently used are usually flat composite patches, when used during surgery, they are difficult to attach smoothly due to the contour of the intestine, resulting in many wrinkles and dead spaces, which can easily cause problems such as effusion infection or hernia recurrence. Therefore, there is a need to improve the existing patches. Utility Model Content

[0005] In view of the above-mentioned technical problems, the utility model provides a parastomal hernia repair patch, which can fit the contour of the intestinal tract, reduce wrinkles and dead space, and thus avoid hernia recurrence.

[0006] The technical solution adopted by this utility model:

[0007] A repair patch for parastomal hernia comprises a patch, which is characterized in that an arched open piece is arranged in the middle of the patch, and a plurality of plastic strips are arranged on the inner wall of the open piece.

[0008] Furthermore, the cross section of the open piece is semicircular, and is half a trumpet shape that gradually shrinks from top to bottom.

[0009] Furthermore, the plastic strips are arranged in groups of two, and a plurality of first fixing nails are arranged between each group of plastic strips.

[0010] Furthermore, a plurality of second fixing nails are evenly arranged on the patch.

[0011] Furthermore, an indication layer is provided on the upper surface of the open sheet.

[0012] Furthermore, an arrow indicating the direction of the opening of the open sheet from large to small is printed on the indicating layer.

[0013] Furthermore, the indicator layer is made of a material that is degradable and absorbable by the human body.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model provides an open patch that matches the curvature of the stoma intestinal tube, so that the stoma intestinal tube can be attached to the abdominal wall, reducing the dead space under the patch, reducing fluid accumulation and infection, and reducing recurrence;

[0016] 2. The utility model provides a plurality of plastic strips distributed along the arc surface on the inner wall of the open sheet, and can further shape the curved surface of the open sheet by extruding the plastic strips, so that it fits more closely to the outside of the stoma intestinal tube, and further cooperates with the first fixing nail to fix it to the stoma intestinal tube and the outside of the abdominal wall;

[0017] 3. The utility model provides an indicating arrow on the upper surface of the open piece, so as to mark the open direction and adjust the position of the patch. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1

[0029] like Figure 1-6As shown, the utility model discloses a repair patch for parastomal hernia, comprising a patch 1, an open piece 2 which is arched upward is integrally formed in the middle of the patch 1, the curvature of the open piece 2 is consistent with the curvature of the stoma intestinal tube, and a plurality of plastic strips 3 are arranged in parallel on the inner wall of the open piece 2, and the arched curvature of the open piece 2 can be fine-tuned by pressing the plastic strips 3, so that it can better adhere to the stoma intestinal tube and the abdominal wall, and no dead cavity will remain to accumulate exudate.

[0030] In order to make the patch fit the contour of the intestinal tract, the open piece 2 is in the shape of a half trumpet that gradually decreases from the outside to the inside, and the cross section of the open piece 2 is a semicircle.

[0031] A plurality of plastic strips 3 are arranged on the inner wall of the open sheet 2, two of each forming a group, and a plurality of first fixing nails 4 are arranged in the gap between the two plastic strips 3 in each group, through which the open sheet 2 and the stoma intestinal tube can be fixed.

[0032] The patch 1 is evenly provided with a plurality of second fixing nails 5, and the patch can be fixed to the abdominal wall by the second fixing nails 5, so as to prevent the patch 1 from moving during the operation and affecting the hernia repair operation.

[0033] During the parastomal hernia repair surgery, pneumoperitoneum is first established through laparoscopy, then adhesions are separated and the hernia contents are retracted, and then the parastomal hernia defect is closed, and then the patch 1 is inserted so that the open piece 2 covers the stoma intestinal tube so that the stoma intestinal tube is close to the lateral abdominal wall, and the patch 1 is fixed by pressing the first fixing nail 4 and the second fixing nail 5. The first fixing nail 4 and the second fixing nail 5 are made of absorbable needles, which can be absorbed and metabolized by the human body later, thereby reducing the patient's discomfort.

[0034] Example 2

[0035] On the basis of Example 1, in order to facilitate the rapid positioning of the patch 1 to the correct position in the patient's body, an indicator layer 6 is provided on the upper surface of the open sheet 2. The indicator layer 6 is made of a human-degradable and absorbable material and will be subsequently absorbed and metabolized by the human body. The indicator layer 6 is printed with arrows 7 indicating the opening of the open sheet from large to small, which help doctors to quickly locate and place the patch 1.

[0036] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any way. Any simple modification, change and equivalent change made to the above embodiment according to the essence of the utility model technology still falls within the protection scope of the technical solution of the utility model.
