Description

Technical Field

[0001] This utility model relates to the field of surgical aids technology, and in particular to a self-filtering protective cover for hysteroscopic surgery. Background Technology

[0002] Hysteroscopy is an endoscope used for the examination and treatment of cervical canal diseases within the uterine cavity. It is mainly suitable for the diagnosis and treatment of abnormal uterine bleeding, endometrial polyps, cervical adhesions, uterine fibroids, and foreign bodies in the cervix. Hysteroscopic surgery is a minimally invasive surgical technique mainly used for intra-abdominal examinations and surgical treatments, such as observing the endometrial environment, removing endometrial polyps, examining uterine septa, or performing tubal patency testing.

[0003] Generally, vaginal irrigation before hysteroscopy can remove pathogens and reduce the risk of postoperative infection. For example, a solution containing antibacterial ingredients such as chlorhexidine can be used to disinfect the vagina to reduce the number of bacteria. Furthermore, during the procedure, irrigation with distending fluid can flush out blood clots, mucosal fragments, and other tissues from the uterine cavity, resulting in a clearer surgical field.

[0004] However, during the cleaning process, the rinsing solution can easily splash onto medical staff or wet the area around the patient, causing discomfort to both. Additionally, when cervical tissue samples need to be taken for testing, the rinsing solution mixes with the tissue and must be collected separately. Current technology uses a filter screen placed under the patient to sieve and filter the tissue. Because hysteroscopy requires deep penetration into the uterine cavity, the mirror's reflection is used to observe the uterine cavity's morphology, endometrial color, fallopian tube openings, and the condition of both cervixes.

[0005] However, this design can easily cause interference when adjusting the angle of the hysteroscope, hindering the smooth operation of medical staff. In severe cases, external interference can cause the hysteroscope to tilt, potentially hitting the patient's uterine tissue, causing trauma, and increasing the risk of infection. Utility Model Content

[0006] In view of this, the present invention aims to provide a self-filtering protective cover for hysteroscopic surgery, which can filter the cleaning water and prevent water from splashing onto medical staff or wetting the patient's body during the cleaning process.

[0007] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0008] A self-filtering protective cover for hysteroscopic surgery includes a main body, a support frame pivotally connected to one end of the main body, and a folding piece connected to the support frame;

[0009] The main body is tapered, and a tapered hole is provided inside the main body.

[0010] The smaller end of the main body abuts against the patient, and the larger end of the main body is used to install the support frame. The main body is also provided with an elastic element for fixing to the patient's legs.

[0011] The support frame includes at least two sub-supports and a linkage mechanism disposed between adjacent sub-supports. A plurality of sub-supports are arranged in a ring along the outer side of the main body. The folding member is arranged in a ring on the sub-supports. When the linkage mechanism is driven to move along the axial direction of the main body, the plurality of sub-supports move closer or further apart, so that the folding member is in a protective state or a guiding state.

[0012] The folding component has a through-hole for water flow.

[0013] Furthermore, the main body has a frustum-shaped structure, and the four sub-supports are respectively connected to the four sides of the main body.

[0014] Furthermore, the sub-support includes a plurality of spaced straight rods, and a connecting shaft that passes through and connects to the plurality of straight rods;

[0015] A number of spaced mounting seats are provided along the outer periphery of the main body, the straight rod is pivotally connected to the mounting seat, and the straight rod and the mounting seat are arranged in a one-to-one correspondence;

[0016] When the straight rods are driven close to the side wall of the main body, the folding member is in a guiding state; when the straight rods are driven close to each other until the main body is away from the patient, the folding member is in a care state.

[0017] Furthermore, the linkage mechanism includes a first link pivotally connected at one end to one of its sub-supports, a second link pivotally connected at the other end of the first link, a third link pivotally connected to the second link, and a fourth link pivotally connected to the third link;

[0018] The fourth link is pivotally connected to another of the sub-supports.

[0019] Furthermore, a first pivot is provided between the first link and the second link, a second pivot is provided between the second link and the third link, and a third pivot is provided between the third link and the fourth link;

[0020] The second link is perpendicular to the third link.

[0021] Furthermore, the first connecting rod and the fourth connecting rod are respectively sleeved on their corresponding connecting shafts.

[0022] Furthermore, the main body has a protruding soft pad at the end closest to the patient, and the soft pad has a groove that matches the shape of the main body. The soft pad is inserted into the main body.

[0023] Furthermore, the folding member includes folding segments connected to the four sub-supports, and connecting segments connecting two adjacent folding segments;

[0024] The end of the folding member near the main body is glued and fixed along the edge of the main body;

[0025] The drainage hole is located in the folded section.

[0026] Furthermore, the folding section has a concave arc section protruding towards the main body. When the folding member is in the protection state, the four concave arc sections form an entrance that protects the outside of the main body.

[0027] Compared with the prior art, this utility model has the following advantages:

[0028] The self-filtering protective cover for hysteroscopic surgery described in this utility model consists of a main body and a support frame and linkage mechanism pivotally connected to the main body. When the linkage mechanism is manually driven to move along the axial direction of the main body, several sub-supports move closer or further apart to form a folded protective or diversion state. This allows the folded cover to be in a diversion state when flushing is not required during hysteroscopic surgery, so that the doctor can easily insert the speculum and hysteroscope, avoiding trauma caused by the hysteroscope touching internal organs due to the confined space.

[0029] Simultaneously, when flushing is needed, medical staff maneuver the folded section into a protective position. During flushing, water flows through the drainage holes into an external receiving bucket or bag. The flushed cervical tissue is trapped within the folded section and the main body. When the water dries, the folded section is maneuvered back into a guiding position, and a special container is used to obtain cervical tissue for sampling. Furthermore, by incorporating elastic elements that fit around the patient's legs, the main body is pressed firmly against the patient's body, making it easy to wear and effectively securing the protective shield.

[0030] Furthermore, by designing the main body as a frustum structure and placing four sub-supports on its four sides, not only is the operating space for medical staff increased, preventing the hysteroscope from being touched, but the installation of the sub-supports is also facilitated. A soft pad is also placed at the end of the main body closest to the patient to improve patient comfort. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0051] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0052] This embodiment relates to a self-filtering protective shield for hysteroscopic surgery, such as... Figures 1 to 5 As shown, the protective cover includes a main body 1, a support frame 2 pivotally connected to one end of the main body 1, and a folding member 3 connected to the support frame 2. The main body 1 is tapered, and a tapered hole 101 is provided inside the main body 1. The end of the main body 1 with a smaller cross-sectional area abuts against the patient, and the end of the main body 1 with a larger cross-sectional area is used to install the support frame 2. The main body 1 is also provided with an elastic member 4 for fixing to the patient's leg.

[0053] The support frame 2 includes at least two sub-supports 201 and a linkage mechanism 202 disposed between adjacent sub-supports 201. Several sub-supports 201 are arranged in a ring along the outer side of the main body 1. The folding member 3 is arranged in a ring on the sub-supports 201. When the linkage mechanism 202 is driven to move axially along the main body 1, the several sub-supports 201 move closer or further apart, so that the folding member 3 is in a protective or guiding state. The folding member 3 is provided with a through-hole 301 for water flow.

[0054] Overall, the hysteroscopic surgery self-filtering protective cover of this embodiment, through the setting of a main body 1 and a support frame 2 and a linkage mechanism 202 pivotally connected to the main body 1, when the linkage mechanism 202 is manually driven to move along the axial direction of the main body 1, several sub-supports 201 move closer or further apart to form a folded part 3 in a care state or a drainage state. This allows the medical staff to drive the folded part 3 into a drainage state when flushing is not required during hysteroscopic surgery, so that the doctor can insert the speculum and hysteroscope and avoid trauma caused by the hysteroscope touching internal organs due to the confined space.

[0055] Simultaneously, when flushing is needed, medical staff can instruct the folding component 3 to be in a protective state. During the flushing process, water flows out through the water outlet 301 into an external receiving bucket or bag. The flushed cervical tissue is trapped within the folding component 3 and the main body 1. When the water dries up, the folding component 3 is instructed to be in a guiding state again, and a special container is used to obtain cervical tissue for sampling. Furthermore, by incorporating an elastic element 4 that is fitted onto the patient's legs, the main body 1 is pressed firmly against the patient's body, making it easy to wear and effectively securing the protective shield.

[0056] Based on the above overall introduction, as Figures 1 to 5 As shown, the elastic element 4 is an elastic band with adhesive buckles. Before surgery, medical staff align the conical hole 101 of the main body 1 with the patient's body and adjust it. After adjusting the position, the elastic element 4 is fixed to the patient's leg. In this embodiment, the elastic bands are respectively set on both sides of the main body 1. In other embodiments, in order to further increase the firmness of the main body 1, straps can also be set at the upper and lower ends of the main body 1 to tie the straps around the patient's waist for further fixation.

[0057] As a preferred embodiment, such as Figures 1 to 7 As shown, the main body 1 has a frustum-shaped structure, with four sub-supports 201 connected to its four sides. By setting the main body 1 as a frustum-shaped structure and placing the four sub-supports 201 on its four sides, not only is the operating space for medical staff increased, preventing the hysteroscope from being touched, but the installation of the sub-supports 201 is also facilitated. Furthermore, the conical orifice 101, with its frustum-shaped design, facilitates the guidance of irrigation fluid, preventing splashing and providing good drainage.

[0058] Furthermore, such as Figure 8 and Figure 9As shown, the support 201 includes several spaced-apart straight rods 2011 and a connecting shaft 2012 that passes through and connects to the several straight rods 2011. Several spaced-apart mounting seats 5 are provided along the outer periphery of the main body 1. The straight rods 2011 are pivotally connected to the mounting seats 5, and each straight rod 2011 corresponds to one mounting seat 5. When the several straight rods 2011 are driven close to the side wall of the main body 1, the folding member 3 is in a guiding state; when the several straight rods 2011 are driven close to each other until the end of the main body 1 furthest from the patient, the folding member 3 is in a care state.

[0059] Combination Figure 8 and Figure 9 As shown, the linkage mechanism 202 includes a first link 2021 pivotally connected at one end to a sub-support 201, a second link 2022 pivotally connected at the other end of the first link 2021, a third link 2023 pivotally connected to the second link 2022, and a fourth link 2024 pivotally connected to the third link 2023. The fourth link 2024 is pivotally connected to another sub-support 201.

[0060] Specifically, such as Figure 9 As shown, a first pivot 2025 is provided between the first link 2021 and the second link 2022, a second pivot 2026 is provided between the second link 2022 and the third link 2023, and a third pivot 2027 is provided between the third link 2023 and the fourth link 2024. The second link 2022 and the third link 2023 are arranged perpendicularly. By providing the first pivot 2025, the second pivot 2026, and the third pivot 2027, the connection between each link is facilitated. By adjusting the length of each pivot, the connection position between each link can be adapted.

[0061] like Figure 9 As shown, the first link 2021 and the fourth link 2024 are respectively sleeved on their corresponding connecting shafts 2012. This arrangement reduces the number of connecting parts and increases the ease of installation.

[0062] It should be noted that the linkage mechanism 202 in this embodiment requires manual operation by medical staff. To meet the needs of surgical automation, a drive cylinder for driving the linkage mechanism 202 can also be installed on the main body 1. The power output shaft of the drive cylinder is fixedly connected to the second rotating shaft 2026. A solenoid valve is connected to the drive cylinder and is connected to the PLC. An on / off button is installed on the operating table and is connected to the PLC. By pressing the button, medical staff can switch the folding part 3 between the care state and the diversion state.

[0063] Preferably, such as Figures 2 to 3As shown, the main body 1 has a protruding soft pad 102 at the end near the patient. The soft pad 102 has a groove that matches the shape of the main body 1, and the soft pad 102 is inserted into the main body 1. In this embodiment, the soft pad 102 is also provided at the end of the main body 1 near the patient to improve the patient's comfort.

[0064] For ease of setup, such as Figures 1 to 4 As shown, the folding member 3 includes folding sections 302 connected to four sub-supports 201, and connecting sections 303 connecting two adjacent folding sections 302. The end of the folding member 3 near the main body 1 is glued and fixed along the edge of the main body 1. A drainage hole 301 is provided on the folding section 302.

[0065] In a preferred embodiment, the main body 1 is made of polyethylene, polyvinyl chloride, nylon, and foam. The folding component 3 in this embodiment is made of materials such as transparent plastic PVC, nylon cloth, and polyester cloth.

[0066] Furthermore, such as Figure 4 and Figure 7 As shown, the folding section 302 has a concave arc section protruding towards the main body 1. When the folding section 3 is in the protection state, the four concave arc sections form an entrance 6 protecting the outside of the main body 1. By setting the concave arc sections, the space requirements for medical staff to operate the hysteroscope are met. Furthermore, when the folding section 3 is in the protection state, medical staff can insert the flushing tube or flushing tube into the speculum through the entrance 6 for flushing. When the folding section 302 is folded up, splashing can be avoided, allowing the continuously flushing fluid to flow out from the drain hole 301.

[0067] Of course, the bag can also be fixed at the connection between the main body 1 and the folding part 3. The bag can be a plastic bag with a support ring. When the flushing fluid flows to the folding part 3, it flows out through the drain hole 301. When the folding part 3 is in the guiding state, the folding section 302 is flattened, and medical staff can hold a tray to receive the uterine cavity tissue left after filtration.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
