Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a peritoneal negative pressure repair patch. Background Art

[0002] Retroperitoneal surgery usually refers to surgery for retroperitoneal tumors. Retroperitoneal tumors refer to tumors that originate in the retroperitoneal space. The characteristics of this type of tumor include no obvious symptoms in the early stages, and they are often large when discovered. The surgery is difficult because the retroperitoneal area has a complex structure and many large blood vessels. General surgeons are not very familiar with this area. Most of them are malignant tumors, but they are less malignant and grow slowly. They tend to push on surrounding organs and blood vessels rather than infiltrate, and rarely metastasize to distant sites.

[0003] The treatment of retroperitoneal tumors is mainly through surgical resection. The operation is difficult and requires highly professional skills. The surgical approach and techniques will be selected according to the location and size of the tumor. It is usually divided into different parts such as the right upper abdomen, left upper abdomen, right lower abdomen, left lower abdomen and pelvis. Tumors in each part have their own specific surgical approaches and techniques, but all require peritoneal incision for surgery.

[0004] Current retroperitoneal surgeries require inflating the retroperitoneum in the patient's body to create a surgical space. If the peritoneum ruptures at this time, the surgical space will collapse. Therefore, a peritoneal patch is needed to repair the ruptured peritoneum. When the patient breathes, gas will be generated in the surgical space. Current patches cannot excrete the gas in the surgical space, have poor air permeability, and are easy to fall off.

[0005] Based on this, the applicant considered designing a peritoneal negative pressure repair patch. Summary of the invention

[0006] In view of the above problems, the present invention provides a peritoneal negative pressure repair patch that overcomes the above problems or at least partially solves the above problems. The technical solution is as follows:

[0007] A peritoneal negative pressure repair patch comprises a patch body, a suction mounting platform and a suction pump, wherein the suction mounting platform is fixedly mounted on the outer side of the patch body, the patch body is provided with a first suction hole, the suction mounting platform is provided with a second suction hole, the first suction hole and the second suction hole are coaxially connected, and the suction pump is connected to the second suction hole on the suction mounting platform for extracting gas between the inner side of the patch body and the peritoneum.

[0008] Compared with the prior art, the peritoneal negative pressure repair patch of the present invention has the following advantages:

[0009] By setting up the patch body, suction mounting platform and vacuum pump, the gas between the patch body and the peritoneum can be discharged through the vacuum pump to form negative pressure, so that the atmospheric pressure outside can automatically stick the patch body to the peritoneum, making it easy to discharge the gas generated in the human body and making it difficult for the patch body to fall off the peritoneum, thereby improving the repair effect.

[0010] The above-mentioned peritoneal negative pressure repair patch has the advantages of simple structure and easy implementation, is suitable for use in the existing peritoneal repair process, and can improve the efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] In a specific implementation, in one embodiment, Figure 1-4As shown, a peritoneal negative pressure repair patch includes a patch body 100, a suction mounting platform 200 and a suction pump 300, wherein the suction mounting platform 200 is fixedly mounted on the outer surface of the patch body 100, the patch body 100 is provided with a first suction hole 110, the suction mounting platform 200 is provided with a second suction hole 210, the first suction hole 110 and the second suction hole 210 are coaxially connected, the suction pump 300 is connected to the second suction hole 210 on the suction mounting platform 200, and is used to extract the gas between the inner side of the patch body 100 and the peritoneum.

[0026] Compared with the prior art, the peritoneal negative pressure repair patch of the present invention has the following advantages:

[0027] By setting up the patch body 100, the suction mounting platform 200 and the vacuum pump 300, the gas between the patch body 100 and the peritoneum can be discharged through the vacuum pump 300 to form a negative pressure, so that the external atmospheric pressure automatically presses the patch body 100 against the peritoneum, making it easy to discharge the gas generated in the human body and making it difficult for the patch body 100 to fall off the peritoneum, thereby improving the repair effect.

[0028] The above-mentioned peritoneal negative pressure repair patch has the advantages of simple structure and easy implementation, is suitable for use in the existing peritoneal repair process, and can improve the efficiency.

[0029] In this embodiment, Figure 1-4 As shown, the vacuum pump 300 is fixedly mounted on the suction mounting platform 200 , and a short suction tube 310 is provided on the vacuum pump 300 . The short suction tube 310 passes through the second suction hole 210 and the first suction hole 110 and is connected to the inner side surface of the patch body 100 .

[0030] In this way, by providing the short suction tube 310, the suction pump 300 can extend into the inner side of the patch body 100 through the short suction tube, so as to facilitate suction of the gas between the inner side and the peritoneum, and the structure is relatively simple.

[0031] In this embodiment, Figure 1-4 As shown, a sealing ring is sleeved on the short suction pipe 310 , and the sealing ring is located in the second suction hole 210 .

[0032] In this way, the sealing ring can prevent the gas between the inner surface and the peritoneum from escaping.

[0033] In this embodiment, Figure 1-4 As shown, a clamping portion is provided on the bottom surface of the vacuum pump 300 for clamping the vacuum pump 300 on the suction mounting platform 200 .

[0034] In this way, the vacuum pump 300 can be more stably installed on the suction mounting platform 200 through the provided clamping portion, and the structure is relatively simple.

[0035] In this embodiment, Figure 1-4 As shown, the clamping portion includes two clamping columns 400, and the two clamping columns 400 are arranged opposite to each other on the bottom surface of the vacuum pump 300, and are perpendicular to the bottom surface of the vacuum pump 300. Two clamping grooves are arranged on the suction mounting platform 200, respectively corresponding to the two clamping columns 400, and the two clamping columns 400 can be respectively clamped into the two clamping grooves.

[0036] In this way, by providing the clamping groove and the clamping column 400, the clamping column 400 can be inserted into the clamping groove for clamping, and the clamping structure is simple, easy to manufacture, and low in cost.

[0037] In this embodiment, Figure 1-4 As shown, positioning feet are provided on the outer periphery of the patch body 100 .

[0038] In this way, the patch body 100 can be further positioned on the peritoneum through the provided positioning feet, and the stability is better.

[0039] In this embodiment, Figure 1-4 As shown, the positioning foot includes a track 610, a spherical slider 620, a connecting rod 630 and a foot pad 640. The track 610 is extended and laid along the outer edge direction of the patch body 100. A sliding groove is opened on the track 610 along the length direction. The spherical slider 620 is slidably set in the sliding groove. One end of the connecting rod 630 is connected to the spherical slider 620 through the notch of the sliding groove, and the other end extends out of the sliding groove and is connected to the foot pad 640.

[0040] In this way, by setting the track 610, the spherical slider 620, the connecting rod 630 and the foot pad 640, the foot pad 640 can be moved along the track 610, so that the positioning point can be adjusted according to the actual situation. The structure is simple and ingenious, and it is easy to install and use.

[0041] During implementation, the track 610 is made of plastic, and the extension direction of the track 610 is consistent with the extension direction of the outer edge of the patch body 100. When the outer edge of the patch body 100 is a straight line, the extension direction of the track 610 is also a straight line. When the outer edge of the patch body 100 is a curve, the extension direction of the track 610 is also a curve.

[0042] In this embodiment, Figure 1-4 As shown, there are multiple positioning feet, which are arranged in an array on the outer periphery of the patch body 100.

[0043] In this way, through multiple positioning feet, the patch body 100 can have more positioning anchor points, further improving stability.

[0044] In another embodiment, if Figure 5 and Figure 6 As shown, the differences are as follows:

[0045] It also includes a long suction tube 320, one end of which is connected to the second suction hole 210, and the other end is connected to the suction pump 300. The suction pump 300 can extract the gas between the inner side of the patch body 100 and the peritoneum through the long suction tube 320.

[0046] In this way, by providing the long suction tube 320, the vacuum pump 300 can be placed outside and does not directly act on the patch body 100, which improves ease of use.

[0047] Among them, Figure 5 and Figure 6 As shown, a one-way valve 500 is disposed in the second suction hole 210 to prevent the gas between the inner side of the patch body 100 and the peritoneum from leaking out of the second suction hole 210 .

[0048] In this way, by providing the one-way valve 500 , the gas between the inner side of the patch body 100 and the peritoneum is not easy to leak out, but will be blocked by the one-way valve 500 , which has a simple structure and is easy to implement.

[0049] The above are only preferred implementations of the present invention. It should be pointed out that a number of modifications and improved technical solutions made by those skilled in the art without departing from the technical solution should also be deemed to fall within the scope of protection required by the claims.
