Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a hysteroscopic specimen collection device. Background Technology

[0002] Hysteroscopy is a minimally invasive gynecological diagnostic and treatment technique. During hysteroscopic surgery, to facilitate operation and avoid obstructing the view, distending fluid is injected into the uterine cavity to expand it to a certain pressure and maintain a large amount of fluid circulation to maintain intrauterine pressure. During the withdrawal of the hysteroscope, intrauterine tissue will flow out along with the distending fluid. Currently, in surgery, either conventional plastic bags are used to collect the outflowing fluid and tissue, which requires medical staff to search for tissue in the fluid, making tissue collection inconvenient, or sterile gauze is used to collect the specimen, which easily leads to the specimen flowing away with the distending fluid, making collection difficult.

Detailed Implementation

[0024] The following is combined Figure 1-3 This utility model will be described in detail.

[0025] A hysteroscopic specimen collection device includes a connecting piece 10 and a collection bag 20. The connecting piece 10 has an operation through hole 101 and a first adhesive layer 102 on its back. The lower end of the connecting piece 10 is connected to the opening side of the collection bag 20. A first filter 30 and a second filter 40 are installed sequentially from top to bottom inside the collection bag 20. The first filter 30 is detachably installed inside the collection bag 20. The diameter of some filter holes in the second filter 40 is smaller than the diameter of some filter holes in the first filter 30. A fixing plate 50 is provided on the back of the connecting piece 10 or the collection bag 20 to assist in fixing the collection device during use. The first filter 30 and the second filter 40 facilitate the separation of tissue specimens and distending fluid flowing into the collection bag 20, realizing specimen collection and separating specimens of different sizes, such as easily separating uterine fibroid tissue and endometrial tissue. The first adhesive layer 102 and the fixing plate 50 together fix the collection device. The overall structure is simple, convenient and practical.

[0026] Specifically, the shape and size of the first filter 30 and the second filter 40 are adapted to the shape and size of the inner cavity of the collection bag 20. The outer walls of the first filter 30 and the second filter 40 are fitted to the side walls of the inner cavity of the collection bag 20. The second filter 40 can be fixedly installed in the inner cavity of the collection bag 20, or it can be detachably connected to the inner cavity of the collection bag 20 by a snap fastener, or the second filter 40 can be placed at the bottom of the inner cavity of the collection bag 20. The bottom of the collection bag 20 is connected to a drain pipe 60, so there is no need to worry about the liquid accumulating in the inner cavity of the collection bag 20 and flowing back upwards, affecting the collection of tissue specimens. The first filter 30 and the second filter 40 are made of rigid materials such as rigid plastic or fixedly connected. The inner wall of the collection bag 20 is made of non-woven fabric, as long as it can make the outer walls of the first filter 30 and the second filter 40 fit against the inner wall of the collection bag 20; the connecting piece 10 is made of medical non-woven fabric, and the first adhesive layer 102 is made of medical pressure-sensitive adhesive; this hysteroscopic specimen collection device is a disposable item to avoid specimen contamination; the patient's buttocks are pressed on the fixation plate 50, which helps the first adhesive layer 102 to fix the collection bag 20. If you want to further improve the fixation of the collection bag 20, you can also provide connecting straps (not shown in the figure) on both sides of the connecting piece 10 or the collection bag 20, and the connecting straps are tied to the patient's groin. Most existing technologies in this field achieve fixation solely through the first adhesive layer 102, so simply having the first adhesive layer 102 is sufficient. The fixing plate 50 and connecting straps are provided to further improve fixation. The filter holes of the first filter screen 30 and the second filter screen 40 can be circular, rhomboid, square, or other shapes. This embodiment only limits the diameter of the filter holes, requiring that the diameter of some filter holes of the second filter screen 40 is smaller than the diameter of some filter holes of the first filter screen 30, without limiting the shape of the filter holes.

[0027] The shape and size of the fixing plate 50 are designed with patient comfort as the primary consideration. The fixing plate 50 can be fixed to the connecting piece 10 and the collection bag 20, or it can be rotatably connected, i.e., a separate long fixing seat (not shown in the figure) is provided, the fixing plate 50 is pivotally connected to the fixing seat, and the connecting piece 10 and the collection bag 20 are then fixed to the fixing seat, so that the fixing plate 50 can rotate upward and downward relative to the fixing seat, thereby achieving the angle adjustment of the fixing plate 50. This makes the patient more comfortable when the fixing plate 50 is placed under the patient's buttocks. In addition, this makes the device easier to package and transport before use. Alternatively, the connecting piece 10 and the collection bag 20 can be detachably connected to the fixing seat by means of snap-fit ​​or adhesive. In this way, the fixing seat and the fixing plate 50 can be reused multiple times, while the connecting piece 10, the collection bag 20, the first filter 30 and the second filter 40 are still disposable.

[0028] In this embodiment, the outer surface of the fixation plate 50 is provided with a soft layer. Specifically, the soft layer is provided to improve the comfort level of the patient when pressing the fixation plate 50 under their body.

[0029] In this embodiment, the first filter 30 is provided with a hanging ear 301 extending from the side near the opening, and the hanging ear 301 is hung on the edge of the opening of the collection bag 20.

[0030] In this embodiment, the sidewall of the first filter 30 is provided with a second adhesive layer, and the first filter 30 is adhered to the inner cavity of the collection bag 20 through the second adhesive layer. Specifically, the second adhesive layer is provided so that the first filter 30 can better adhere to the inner wall of the collection bag 20. Regarding whether the process of removing the first filter 30 will cause the tissue on the surface of the first filter 30 to fall into the lower part of the inner cavity of the collection bag 20 due to shaking, for this convenience, the second adhesive layer can be omitted. Instead, a rigid ring strip can be provided on the side wall edge of the first filter 30 so that the side wall edge of the first filter 30 abuts against the inner wall of the collection bag 20 to complete the adhesion. Alternatively, the collection bag 20 can be disassembled into a first bag body and a second bag body. The first filter 30 and the second filter 40 are respectively fixed in the inner cavities of the first bag body and the second bag body. The top of the second bag body can be detachably connected to the outer wall of the first bag body by hanging or adhesive (there is no gap between the first bag body and the second bag body in the height direction to prevent liquid from splashing out from the gap between them). In this way, when you want to separate the first filter 30 and the second filter 40, you can directly separate the first bag body and the second bag body.

[0031] In this embodiment, a support strip 201 is provided along the edge of the opening of the collection bag 20; furthermore, the support strip 201 is an aluminum strip. The support strip 201 is provided to open the opening of the collection bag 20 to facilitate subsequent collection work.

[0032] In this embodiment, the first adhesive layer 102 is bonded with release paper, which has an easy-tear strip. Specifically, when not in use, the release paper protects the adhesive surface of the first adhesive layer 102 to maintain its good adhesion; the easy-tear strip is a long, protruding strip that makes it easy to tear off the release paper.

[0033] In this embodiment, the bottom of the collection bag 20 is provided with a drain pipe 60, which connects to the inner cavity of the collection bag 20. Specifically, the drain pipe 60 forms a drain channel inside. The drain pipe 60 is designed to drain the liquid in the inner cavity of the collection bag 20, and also to avoid the phenomenon that the first adhesive layer 102 will not adhere properly due to excessive liquid in the inner cavity of the collection bag 20.

[0034] In this embodiment, a valve (not shown in the figure) is installed on the outer wall of the drain pipe 60. Specifically, the valve can control the opening and closing of the drain channel and the flow rate of the drain. In case of an emergency, the drain channel can be closed in time by the valve.

[0035] The hysteroscopic specimen collection device proposed in this utility model is used as follows:

[0036] The fixation plate 50 is placed under the patient's buttocks. Then, the operating port 101 is aligned with the patient's vulva. The release paper is peeled off from the outside of the first adhesive layer 102 using the easy-tear strip. The first adhesive layer 102 is then attached to the patient's vulva or surgical drape, thus securing the collection bag 20. Next, instruments such as the hysteroscope are inserted and removed from the patient's vagina through the operating port 101 of the connecting piece 10 to perform hysteroscopic surgery.

[0037] During the withdrawal of the hysteroscope, intrauterine tissue will flow out of the vagina along with the distending fluid, and flow into the inner cavity of the collection bag 20 through the operation port 101 and the opening of the collection bag 20. Larger specimens, i.e. larger tissues, will be intercepted by the first filter 30, while smaller specimens, i.e. smaller tissues, and the liquid will continue to flow downwards due to their own gravity. Then, the smaller specimens will be intercepted by the second filter 40, thus achieving secondary collection of the specimens and enabling better classification and collection of the tissue specimens. The liquid will continue to flow downwards and eventually be discharged from the drain tube 60.

[0038] After the surgery, in order not to affect the extraction of tissue from the surface of the second filter 40, the first filter 30 needs to be removed first: detach the loop 301 from the opening edge of the collection bag 20, and then lift the first filter 30 by the loop 301. Afterwards, extract the tissue from the surface of the first filter 30, and then extract the tissue from the surface of the second filter 40 for pathological examination.

[0039] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
