[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0024] The present application embodiment discloses a non-contact hysteroscope leak-proof insertion device. Figure 1 The non-contact hysteroscope leak-proof insertion device comprises a protective film 1 and a blocking member 2 arranged on the protective film 1. The protective film 1 is a non-toxic and harmless medical transparent film. The protective film 1 is a PU surgical film or a PE surgical film. In this embodiment, the protective film 1 is a PE surgical film. A sticky layer is provided on one side of the protective film 1. The sticky layer adopts a sticky resin material or a polypropylene sticky material. In this embodiment, the sticky layer adopts a sticky resin material. The protective film 1 is bonded to the patient's skin through the sticky layer, thereby playing a role in fixing the protective film 1.
[0025] Reference Figure 1 An operation port 11 is provided on the protective film 1, which is convenient for the doctor to pass the instrument through the protective film 1 to perform hysteroscopic surgery on the patient. The blocking member 2 is arranged in the operation port 11, and the blocking member 2 can block the operation port 11, and the medical instrument can pass through the blocking member 2 to enter the patient's vagina and uterine cavity for surgical operation.
[0026] Before performing non-contact hysteroscopic surgery, the side of the protective film 1 with the adhesive layer is adhered to the patient's skin so that the protective film 1 seals the patient's vaginal opening. The transparent protective film 1 can facilitate the surgeon to quickly and accurately locate the protective film 1 so that the operating port 11 is aligned with the patient's vaginal opening, so as to facilitate hysteroscopic surgery. The instrument is passed through the blocking member 2 to perform the surgical operation, and the blocking member 2 blocks the operating port 11 to prevent the expansion medium in the vagina from flowing out.
[0027] Specifically, refer to Figure 2 The blocking member 2 includes a membrane valve ring 21 and a plurality of flexible membrane valves 22. The membrane valve ring 21 is a circular ring. The membrane valve ring 21 has the same shape and size as the operation port 11. The thickness of the membrane valve ring 21 ranges from 0.2 to 0.25 cm, and the thickness of the flexible membrane valve 22 ranges from 0.1 to 0.2 cm. The plurality of flexible membrane valves 22 are arranged on the inner wall of the membrane valve ring 21. In a natural state, the plurality of flexible membrane valves 22 together fill the interior of the membrane valve ring 21.
[0028] In this embodiment, the operation port 11 is a circular hole, the membrane petal ring 21 is located on the side of the protective film 1 close to the adhesive layer, the inner diameter of the membrane petal ring 21 is the same as the diameter of the operation port 11, the membrane petal ring 21 is concentrically arranged with the operation port 11, and the side of the membrane petal ring 21 close to the protective film 1 is bonded and fixed to the adhesive layer on the protective film 1. In this embodiment, there are eight flexible membrane petals, and eight flexible membrane petals 22 are arranged on the inner peripheral wall of the membrane petal ring 21. The flexible membrane petals 22 and the membrane petal ring 21 are integrally formed. The eight flexible membrane petals 22 are fan-shaped sheets of the same size, and the adjacent flexible membrane petals 22 are staggered and fitted along their own thickness direction, that is, there is at least a partial overlap between the adjacent flexible membrane petals 22, and the area of the overlap surface is one tenth of the area of a single flexible membrane petal 22. The area ratio can be appropriately adjusted according to actual applications. The mutually staggered, overlapping and fitted arrangement between adjacent flexible membrane petals 22 can improve the sealing between multiple flexible membrane petals 22, thereby improving the anti-leakage ability of the plugging member 2.
[0029] As an alternative embodiment, the operation port 11 and the membrane flap ring 21 may also be vertically arranged in an elliptical shape, and the multiple flexible membrane flaps 22 may be fans of different sizes to adapt to the shape of the patient's vaginal opening, thereby increasing the effective blocking area of the blocking member 2.
[0030] Reference Figure 3 , an extension layer 23 is provided on the outer peripheral side of the membrane valve ring 21, and the extension layer 23 is integrally formed with the membrane valve ring 21. The extension layer 23 is annular, and its inner diameter is the same as the outer diameter of the membrane valve ring 21, and its outer diameter ranges from 2.5 to 3.5 cm. Its thickness is consistent with the thickness of the membrane valve ring 21, and its thickness gradually decreases from top to bottom, that is, the extension layer 23 is truncated cone as a whole, and its top is flush with the top of the membrane valve ring 21, and its bottom is flush with the bottom of the membrane valve ring 21. By bonding the extension layer 23 with the adhesive layer of the protective film 1, the contact area between the blocking member 2 and the adhesive layer can be increased, thereby improving the adhesion stability of the blocking member. The design of the gradually thinning thickness of the extension layer 23 can make the blocking member 2 smoother as a whole, and improve the comfort of the patient.
[0031] The membrane valve ring 21, the flexible membrane valve 22 and the extension layer 23 are all made of flexible materials, which can be silicone materials or natural latex materials. In this embodiment, silicone materials are used. The flexible material enables the membrane valve ring 21 and the flexible membrane valve 22 to have a certain flexibility while having water-proof properties, which makes it easy for the membrane valve ring 21 to fit the patient's skin and for hysteroscopic instruments to pass through the flexible membrane valve 22.
[0032] In a natural state, the multiple flexible membrane flaps 22 are in a sealed state of mutual contact, and the membrane flap ring 21 is blocked. During non-contact hysteroscopic surgery, the hysteroscopic instrument pushes the flexible membrane flap 22, so that the contact point between the flexible membrane flap 22 and the hysteroscopic instrument is deformed. After the hysteroscopic instrument passes through the flexible membrane flap 22, a wide range of angle adjustment can be performed, thereby facilitating the operation of the surgery. The non-deformed point of the flexible membrane flap 22 can still maintain a natural state, thereby playing a role in blocking the outflow of the expansive fluid medium in the vagina.
[0033] The inner diameter of the membrane valve ring 21 along the direction parallel to the protective membrane ranges from 0.5 to 1.5 cm. The specific size can be selected according to the patient's body shape. By selecting a suitable diameter of the membrane valve ring 21, the fit between the sealing member 2 and the patient's vaginal opening can be improved, thereby improving the leakage prevention ability of the device of the present application.
[0034] The length and width of the protective film 1 are both in the range of 20 to 40 cm, which is convenient for adhering the protective film 1 to the outer peripheral side of the patient's genitals. In the present embodiment, the protective film 1 is a square film with a length and width of 30 cm, which is convenient for mass production of the protective film. As an alternative embodiment, the protective film 1 may also be an irregular shape, for example, arc-shaped notches are provided on both sides of the rectangular protective film 1, and the arc-shaped notches can adapt to the contour of the patient's thigh, so as to facilitate the protective film 1 to be smoothly adhered to the patient's skin.
[0035] The embodiment of the present application is a non-contact hysteroscope leak-proof insertion device and is also used in conjunction with a bed sheet, which includes an integrally formed abdominal shielding portion, a perineum shielding portion, a buttocks shielding portion and two leg covers, wherein the perineum shielding portion, the buttocks shielding portion and the two leg covers are all located on the side of the abdominal shielding portion away from the patient's head, and the two leg covers are respectively connected to the two ends of the abdominal shielding portion, the perineum shielding portion is located in the middle of the two leg covers and is connected to the abdominal shielding portion, and the buttocks shielding portion is connected to the perineum shielding portion and the two leg covers. An operating port is provided on the perineum shielding portion, and the operating port is the same shape as the protective film and is slightly smaller than the protective film. A collection container is provided below the perineum shielding portion near the operating port, and the collection container is detachably connected to the perineum shielding portion through Velcro, and the collection container can collect vaginal outflow medium to cope with unexpected situations such as heavy bleeding of the patient during the operation.
[0036] When using the drape, the two leg covers are put on the patient's legs, so that the abdomen covering part covers the patient's abdomen, the perineum covering part covers the patient's perineum, and the under-buttocks covering part covers the patient's under-buttocks. The protective film 1 is then adhered to the surgical opening of the drape, the position of the protective film 1 is adjusted, the blocking piece 2 is aligned with the patient's vaginal external opening, and the protective film 1 is then adhered to the patient's vaginal external opening to fix the position of the blocking piece 2 for easy surgery.
[0037] The implementation principle of a non-contact hysteroscopic leak-proof insertion device according to an embodiment of the present application is as follows: a protective film 1 with a sticky layer is adhered to the patient's skin, an operating port 11 on the protective film 1 is aligned with the patient's vaginal external opening, the protective film 1 seals the patient's vaginal external opening, a membrane valve ring 21 and a plurality of flexible membrane valves 22 made of silicone material are arranged in the operating port 11, and the plurality of flexible membrane valves 22 seal the membrane valve ring 21. During the non-contact hysteroscopic surgery, after the hysteroscopic instrument passes through the flexible membrane valve 22, the non-deformed part of the flexible membrane valve 22 can still produce a leak-proof effect, thereby achieving the effect of hindering the outflow of vaginal expansion medium during the non-contact hysteroscopic surgery.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
