Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a vaginal occluder for gynecological surgery. Background Art

[0002] At present, in laparoscopic minimally invasive surgery, CO2 gas needs to be filled into the abdominal cavity to maintain pneumoperitoneum pressure and keep the abdominal cavity filled to provide an operating space. Most gynecological surgeries are minimally invasive. Due to the need to remove the uterus due to the disease, after the hysterectomy, the pelvic floor peritoneum is opened, and the abdominal cavity is connected to the outside world through the vaginal stump. CO2 gas escapes, so the vaginal stump needs to be blocked to maintain a certain pressure in the abdominal cavity for the next operation.

[0003] The traditional method is to stuff two pieces of gauze into a ball in a glove and insert it into the patient's vagina for occlusion. However, due to the loose fixation and easy slippage, manual mechanical occlusion is required, which wastes manpower when medical staff are in short supply. The surgical inventory system stipulates that four items must be counted. Conventionally, two pieces of gauze are stuffed into the glove, but sometimes one or three pieces are filled in due to confusion, resulting in the formation of adverse events such as unclear counting. In order to solve this technical problem, a vaginal occluder for gynecological surgery is proposed. Utility Model Content

[0028] The utility model is a whole, and it is convenient to count during the operation.

[0029] It should be noted that the hand-held part 10 may be a rod-shaped plastic part and may have a certain degree of elasticity.

[0030] Specifically, the expansion part 20 may include an elastic support rod 203 fixedly arranged at the first end of the handheld part 10, the outer diameter of the elastic support rod 203 is smaller than the outer diameter of the handheld part 10, the outer side of the elastic support rod 203 may be wrapped with a water-absorbing expansion layer 202, the outer side of the water-absorbing expansion layer 202 may be wrapped with an elastic waterproof layer 201, and the first end of the elastic waterproof layer 201 is connected to the first end of the handheld part 10; the elastic support rod 203 passes through the installation through hole on the elastic waterproof layer 201 and is exposed outside the second end of the elastic waterproof layer 201; the anti-slip structure 2011 is arranged outside the elastic waterproof layer 201; and a plurality of water inlet holes 2012 are arranged on the second end of the waterproof layer 201. The anti-slip structure 2011 is arranged to prevent slipping and improve the stability of the utility model during use. The elastic support rod 203 may be an elastic rubber rod.

[0031] When in use, the assistant doctor holds the handheld part 10 and inserts the utility model into the patient's body through the vagina, then injects physiological saline into the elastic waterproof layer 201 through the water inlet hole 2012 at the top of the elastic waterproof layer 201, and then enters the water absorption and expansion layer 202. The water absorption and expansion layer 202 absorbs water and automatically expands. After expansion, the purpose of blocking the vaginal stump is achieved, preventing CO2 gas from escaping, maintaining a certain pressure in the abdominal cavity, and providing a certain operating space for the doctor to perform the next step of the operation; at the same time, an anti-slip structure 2011 is set on the outside of the elastic waterproof layer 201 to improve the stability of the utility model during use. The utility model itself is a whole, and it is also relatively simple to count during use.

[0032] As a preferred embodiment of the present invention, a plurality of water inlet holes 2012 are arranged in an array around the elastic support rod 203 on the elastic waterproof layer 201. Specifically, the number of the water inlet holes 2012 can be two, three, four or five, and the specific arrangement can be set as needed.

[0033] The elastic waterproof layer 201 can be made of a non-toxic and harmless elastic waterproof material. Specifically, the elastic waterproof layer 201 can be an elastic rubber layer. In this way, the elastic waterproof layer 201 is non-toxic and harmless, and has elasticity and can be stretched.

[0034] It should be noted that the elastic waterproof layer 201 can be a cylindrical structure as a whole in the unexpanded state, the first end of the elastic waterproof layer 201 can be set as an opening, and the opening of the elastic waterproof layer 201 is fixedly installed along the outer side of the first end of the hand-held part 10; the elastic support rod 203 is set through the second end of the elastic waterproof layer 201.

[0035] As a preferred embodiment of the present invention, the first end of the handheld portion 10 is larger than the second end, wherein the second end is mainly used for handholding, and the first end of the handheld portion 10 is provided with a transition section in the middle of the handheld portion 10. If the handheld portion 10 is designed as a cylindrical structure, the diameter of the transition section is gradually changed. Specifically, the outer diameter of the transition section is gradually reduced from the first end of the handheld portion 10.

[0036] As a preferred embodiment of the utility model, the water-absorbing and expanding layer 202 includes a wrapping part and an expanding part, the expanding part is wrapped by the wrapping part, the expanding part can be a water-absorbing resin, an expanding sponge or a water-absorbing and expanding rubber; the wrapping part can be an elastic mesh structure, and other components that are water-permeable and can protect the water-absorbing resin material.

The water-absorbing and expanding layer 202 is wound around the outside of the elastic support rod 203 in a circle.

[0038] It should be noted that super absorbent polymer (SAP) is a new type of functional polymer material. It has a high water absorption function of absorbing water hundreds to thousands of times heavier than its own weight, and has excellent water retention performance. Once it absorbs water and swells into a hydrogel, it is difficult to separate the water even under pressure.

[0039] It should be noted that water-swelling rubber contains a sufficient amount of hydrophilic groups or substances. When it comes into contact with water, water molecules will enter its interior through surface adsorption, capillary action and diffusion, and form a strong binding force with the hydrophilic groups or substances in the material. As the water molecules continue to increase, the material will expand and deform. Water-swelling rubber is a new type of functional polymer material developed in the late 1970s. Water-swelling rubber is made by introducing hydrophilic groups or hydrophilic components into the rubber matrix. After absorbing water, it can expand to several times or even hundreds of times its own mass or volume, filling the irregular surfaces, holes and gaps it contacts, and at the same time generating huge contact pressure to achieve the effect of sealing and water stopping.
