Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a disposable urology transurethral surgery fluid collection bag device. Background Art

[0002] Due to the widespread development of minimally invasive surgeries in intracavitary urological surgery, especially transurethral prostate vaporization electroresection, transurethral bladder tumor resection, transurethral ureteral lithotripsy and other surgeries, in order to maintain the clarity of the endoscopic surgical field of view during the operation, a large amount of irrigation fluid (at least 6000 ml, generally about 30000 ml for transurethral prostate surgery) is required. These flushing liquids eventually flow out from the side holes of the electroresectomoscope or ureteroscope, often resulting in the sterile sheet being soaked and failing to play a protective role. At the same time, a large amount of liquid accumulates on the ground, causing inconvenience to doctors. In the prior art, a disposable brain surgery film is used on the perineum. The film has a built-in liquid collection bag. The upper opening of the liquid collection bag is opened, and the lower opening is placed in a bucket to receive a large amount of liquid flowing out during the operation to prevent the sterile sheet and the ground from being soaked.

[0003] For example, the utility model patent with publication number CN217040297U and authorization announcement date July 26, 2022, is named "A special surgical film for percutaneous nephrolithotomy in urology". The patent discloses a special surgical film for percutaneous nephrolithotomy in urology, which belongs to the field of medical device technology, including a drainage bag, and the lower end of the drainage bag is detachably connected to a collection box, the lower end of the collection box is configured with a liquid outlet tube, and a collection drawer is slidably installed in the middle part of the collection box, and a through opening is opened on the inner bottom surface of the collection drawer, and a filter mesh is arranged on the through opening. The special surgical film for percutaneous nephrolithotomy in urology can filter surgical waste fluid through the collection drawer and the filter mesh in the collection box. The collection box can be detachably installed on the lower end of the drainage bag, and then with the liquid inlet tube, the drainage bag can be connected with the inside of the collection box, so that it is convenient to filter the waste fluid and collect stones through the collection box, so that the stones are collected in the collection drawer, and the liquid flows into the drainage tube through the liquid outlet tube to be introduced into the waste liquid container, so that the stones can be collected without the need for postoperative scooping, and it is easy to use.

[0004] The shortcomings of the above-mentioned patents are that the fluid collection bags used in clinical practice have poor opening maintenance capabilities. During surgery, the two layers of the fluid collection bag often stick together, and water easily flows out of the bag when flushing, causing water to accumulate on the surgical floor and wet the sterile sheets or the surgeon's surgical gown, increasing the risk of hypothermia and chills during surgery for patients, and the surgeon may also slip when moving during surgery.

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0025] Refer to Figures 1-3, a disposable urological transurethral surgery fluid collection bag 4 device provided by an embodiment of the present utility model, includes a film pasting mechanism 1 and a fluid collection bag 4 connected to the film pasting mechanism 1. A ring-shaped expansion mechanism 3 is further provided at the opening edge position of the fluid collection bag 4. The ring-shaped expansion mechanism 3 has a first state and a second state. In the first state, the ring-shaped expansion mechanism 3 adheres to the fluid collection bag 4. In the second state, the ring-shaped expansion mechanism 3 expands into a ring shape.

[0026] Specifically, as Figures 1-3 shown, the film pasting mechanism 1 includes a film. The film is a sticky medical plastic film, commonly a square structure, that is, it includes four sides. Before the surgery starts, the film pasting mechanism 1 is adhesively fixed to the lower abdomen of the patient. An opening is provided in the middle area of the film pasting mechanism 1 for the surgical site to leak out for the entry and exit of urological surgical instruments such as catheters. This is prior art and will not be elaborated. One of the bottom sides (the side facing the patient's feet during use) of the four sides of the film pasting mechanism 1 is connected to the fluid collection bag 4. The fluid collection bag 4 includes an upper opening and a lower opening, that is, both its upper and lower parts are in an open state. The upper opening of the fluid collection bag 4 is connected to the film pasting mechanism 1, and the lower opening of the fluid collection bag 4 is connected to a water bucket to facilitate the storage of the flushing liquid. The fluid collection bag 4 is an inverted triangular cone shape. The maximum diameter of the upper opening of the fluid collection bag 4 is 90 cm. A ring-shaped expansion mechanism 3 is further provided at the upper opening edge position of the fluid collection bag 4. The width of the ring-shaped expansion mechanism 3 is 5 cm. Optionally, the ring-shaped expansion mechanism 3 is an airbag or a waterbag. A valve 8 and a plug 9 are further provided on the ring-shaped expansion mechanism 3. The valve 8 and the plug 9 are used to ensure the airtightness of the ring-shaped expansion mechanism 3 and can open the plug 9 to release gas or liquid after use. In the first state, the ring-shaped expansion mechanism 3 adheres to the fluid collection bag 4. This is the state before use. During use, the ring-shaped expansion mechanism 3 is in the second state. A 50 ml syringe can be used to inject air or liquid into the ring-shaped expansion mechanism 3 to make it expand into a ring shape. Under the action of the gas, the ring-shaped expansion mechanism can not only hold the flowing liquid and let it enter the fluid collection bag 4, but also has flexibility and will not interfere with the operation during the surgery. Moreover, the ring shape of the ring-shaped expansion mechanism 3 surrounds the upper opening edge of the fluid collection bag 4 and expands the upper opening of the fluid collection bag 4, so that it will not fit together during the surgery, avoiding the flushing liquid from wetting the ground and the sterile sheet.

[0027] A disposable urological transurethral operation fluid collection bag 4 device provided by the present utility model. Before the operation starts, the film pasting mechanism 1 is pasted on the lower abdomen of the patient. The film pasting mechanism 1 is connected to the fluid collection bag 4. A ring-shaped expansion mechanism 3 is arranged at the opening edge position of the fluid collection bag 4. In the first state, the ring-shaped expansion mechanism 3 is attached to the fluid collection bag 4. After the operation starts, a 50 ml syringe can be used to inflate gas into it. At this time, the ring-shaped expansion mechanism 3 is in the second state and expands into a ring shape to surround the edge of the fluid collection bag 4. In this way, the ring-shaped expansion mechanism 3 expands the opening of the fluid collection bag 4 so that it will not fit during the operation.

[0028] In another embodiment provided by the present utility model, as Figure 3 shown, an opening 2 is arranged on the film pasting mechanism 1. The shape of the opening 2 is preferably oval. In this way, the opening 2 is for male patients. At the position of the opening 2, it is double-layer film 10 so that it will not fall off during the operation. The lower abdomen of the patient is single-layer film. A strap is arranged on the edge of the opening 2. When in use, the penis can be taken out from the opening 2. After tightening the strap, the edge of the double-layer film 10 can be fixed around the penis, so as to ensure to the greatest extent that the film pasting mechanism 1 can be firmly pasted on the patient. The tie around the penis can adjust the closing size according to different volumes to keep the tightness at the opening 2, and the tension of the tie is not too high.

[0029] In still another embodiment provided by the present utility model, as Figure 1 shown, it further includes a drainage catheter 6. One end of the drainage catheter 6 is connected to the lower opening of the fluid collection bag 4. The other end of the drainage catheter 6 is connected to a plastic water bucket, etc. The drainage catheter 6 is made of plastic. The diameter of the drainage catheter 6 is 5 cm. A sieve-shaped plastic film 5 is arranged at the part where the drainage catheter 6 is connected to the fluid collection bag 4. The diameter of the sieve holes on the sieve-shaped plastic film 5 is 0.3 cm. The sieve-shaped plastic film 5 can help block the tissue specimens washed out from being washed down the drainage catheter 6. The purpose of setting the sieve-shaped plastic film 5 in this way is to collect the tissue samples washed out by the flushing fluid during the operation, saving the time of using a flushing ball to flush out the samples and then washing out the samples during the operation, and improving the operation efficiency.

[0030] In an optional embodiment, a tear line part is arranged in the area where the bottom of the fluid collection bag 4 is adjacent to the sieve-shaped plastic film 5, and the sieve-shaped plastic film 5 is configured to be concave. The function of such a setting is that when it is necessary to take samples after the operation, directly tear off the tear line part, and then pour out the tissue samples in the sieve-shaped plastic film 5 by turning it over, which is quick and convenient.

[0031] In yet another embodiment provided by the present utility model, as Figure 2As shown, the annular expansion mechanism 3 is an airbag and is a double-layer inflatable film 7. The double-layer inflatable film 7 is not easily broken and is convenient to inflate. A valve 8 and a plug 9 are also provided on the double-layer inflatable film 7. The valve 8 and the plug 9 are used to ensure the airtightness of the annular expansion mechanism 3 and can release gas or liquid by opening the plug 9 after use. During use, a 50-ml syringe can be used to inject air into the annular expansion mechanism 3. After use, the air can be released through the valve 8. It has no redundant structure and is also convenient to store before use.

[0032] Only some exemplary embodiments of the present invention have been described by way of illustration above.
