[0055] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0056] Uterine fibroids are the most common benign tumor of the female genitalia and the most common tumor in the human body. They form as a proliferation of uterine smooth muscle tissue, interspersed with small amounts of fibrous connective tissue. They may be single or multiple. Depending on the size and location of the tumor, clinical symptoms often include menorrhagia, dysmenorrhea, vaginal discharge, abdominal mass, infertility, and anemia. They are most common in women aged 30 to 50, with the highest incidence in those aged 40 to 50, and are rare in those under 20. While the incidence is difficult to determine, autopsy data indicate that approximately 20% of women over 35 have uterine fibroids. Because many patients are asymptomatic or the fibroids are very small, the reported incidence is far lower than the actual rate.

[0057] The latest treatment device available is Gynesonics, a California-based women's healthcare company. Its next-generation uterine fibroid ablation device combines intrauterine ultrasound guidance with targeted radiofrequency ablation to treat symptomatic uterine fibroids, including those associated with heavy menstrual bleeding, using an incision-free procedure. This system offers a groundbreaking alternative to hysterectomy and myomectomy. It allows for transcervical delivery, avoiding damage to the abdominal cavity and eliminating the need for general anesthesia. It can also treat most types of fibroids, including submucosal, intramural, transmural, and subserosal fibroids.

[0058] Existing uterine fibroid ablation devices are diagnostic and treatment devices that combine an ultrasonic handle with a radiofrequency puncture handle. Traditional radiofrequency puncture handles utilize a combination of a puncture needle and an electrode needle in their puncture structure. The RF puncture handle uses a first and second sliding key to advance the electrode needle. If the first sliding key pushes the puncture needle, and the second sliding key pushes the electrode needle to the target position, the needle alone can become stuck in the fibroid tissue. This can easily cause the treatment electrode needle to slip, causing the ablation zone to shift, failing to reach the intended treatment area, and potentially causing damage to surrounding tissue.

[0059] In addition to the aforementioned electrode needles, traditional radiofrequency ablation procedures require the patient to be attached with electrodes to form a circuit. This restricts treatment to patients with metal implants and poses a risk of burns. Furthermore, the combined puncture needle and electrode needle increases the size of the puncture wound.

[0060] The following combination Figures 1-11 The present invention describes a uterine fibroid steam ablation puncture handle device, which is used to solve the problems of sliding of the puncture structure in related technologies, causing changes in the expected ablation treatment area, and the risk of causing damage to surrounding tissues, and has certain limitations and increases the area of ​​the puncture wound.

[0061] It is understandable that, referring to Figures 1 to 7 In an embodiment of the present invention, a uterine fibroid steam ablation puncture handle device is provided, comprising a housing 100, a puncture catheter assembly 300, a sliding assembly 400, and an operating mechanism 600. A stop structure 210 is fixedly provided in the housing 100. The puncture catheter assembly 300 includes a puncture needle 310, which is slidably disposed in the housing 100 and extends out of the housing 100. The sliding assembly 400 is slidably disposed in the housing 100 and is fixedly connected to the puncture needle 310. A locking structure 500 is movably provided on the sliding assembly 400, and the locking structure 500 is used to detachably contact and cooperate with the stop structure 210 to lock or unlock the sliding of the sliding assembly 400. The operating mechanism 600 is slidably disposed in the housing 100, and the operating mechanism 600 slides to drive the sliding assembly 400. The operating mechanism 600 is transmission-connected to the locking structure 500, and the operating mechanism 600 has a first state and a second state.

[0062] In the first state, the locking structure 500 contacts and cooperates with the stopping structure 210 to limit the sliding of the sliding assembly 400; in the second state, the operating mechanism 600 drives the locking structure 500 to move to separate from the stopping structure 210 to release the restriction on the sliding of the sliding assembly 400; after the sliding assembly 400 slides to the target position, the operating mechanism 600 resets to the first state.

[0063] The uterine fibroid steam ablation puncture handle device provided by the present invention has the puncture needle 310 in the initial position. When the operating mechanism 600 is in the first state, the locking structure 500 contacts and cooperates with the stop structure 210 to limit the sliding of the sliding assembly 400 relative to the shell 100, and then limits the sliding of the puncture needle 310; when sliding is required, the operating mechanism 600 is placed in the second state, and the locking structure 500 is driven by the operating mechanism 600 to move to separate from the stop structure 210 to release the restriction on the sliding assembly 400, so that the sliding part can slide relative to the shell 100 and slide to the target position; after sliding to the target position, the operating mechanism 600 is reset to the first state, and the locking structure 500 returns to contact and cooperate with the stop structure 210, and then locks the sliding assembly 400 and the puncture needle 310.

[0064] Therefore, it can be understood that through the cooperation between the sliding assembly 400, the operating mechanism 600, the stop structure 210 and the locking structure 500, the puncture needle 310 can be locked after being pushed to the target position, that is, self-locking, to avoid the puncture needle 310 sliding after puncture is in place and causing mistreatment, thereby improving the safety of use, thereby helping to avoid changes in the expected treatment area of ​​ablation and preventing damage to surrounding tissues.

[0065] It should be noted that, in the embodiment of the present invention, the puncture needle 310 can slide toward the front end of the housing 100 through the operating mechanism 600 and the sliding assembly 400 to perform diagnosis and treatment.

[0066] It is understandable that, referring to Figure 1 and Figure 2 In some embodiments of the present invention, the housing 100 includes an upper handle shell 110 and a lower handle shell 120 connected to the upper handle shell 110. The upper handle shell 110 and the lower handle shell 120 can be connected by, for example, screws and nuts, a snap connection, etc. In this embodiment, a sliding channel is formed between the upper handle shell 110 and the lower handle shell 120 to prevent the operating mechanism 600 from sliding.

[0067] It is understandable that, referring to Figures 4 to 7 In some embodiments of the present invention, the operating mechanism 600 includes an operating member 610 that can move relative to the housing 100; the locking structure 500 includes a toggle member 510, which is rotatably connected to the sliding assembly 400, and a locking portion 511 is provided on the toggle member 510, which is used to plug and cooperate with the stop structure 210 to limit the sliding assembly 400 from sliding relative to the housing 100; wherein the operating member 610 is transmission-connected to the toggle member 510, and the locking portion 511 can rotate with the toggle member 510 until it is separated from the stop structure 210.

[0068] With the above structure, when the operating mechanism 600 is in the first state, that is, the natural static state, the locking portion 511 of the toggle member 510 is plugged into and matched with the stop structure 210 to achieve locking, and the sliding assembly 400 (including the puncture needle 310) is fixed at a specific position of the housing 100 to prevent the puncture needle 310 from moving accidentally; when sliding is required, the operating member 610 is driven to move so that the operating mechanism 600 switches to the second state, causing the toggle member 510 to deflect, and the locking portion 511 is disengaged from the stop structure 210. At this time, the operating mechanism 600 can be pushed to drive the sliding assembly 400 to slide toward the front end of the housing 100 to the target position, so that the front end of the puncture needle 310 also slides to the target position, and the sliding positions of the sliding assembly 400 and the puncture needle 310 are accurately controlled; by simply driving the operating member 610, the user can easily achieve locking and unlocking, the operation is intuitive and convenient, and the device structure can be made compact.

[0069] Of course, in some embodiments, the toggle member 510 can also be configured to be slidably connected to the sliding assembly 400, and the locking structure 500 and the stop structure 210 can be plugged in or separated by sliding the toggle member 510, which is not limited here; or the toggle member 510 can also be configured to be a retractable structure, which is not limited here.

[0070] It can be understood that, in this embodiment, the locking portion 511 and the stopping structure 210 are plug-fitted; of course, in some embodiments, the locking portion 511 and the stopping structure 210 can also be abutted, which is not limited here.

[0071] Specifically, refer to Figure 8 and Figure 9 In some embodiments of the present invention, the operating member 610 is configured to be slidable. The operating member 610 includes a sliding button 611 and a button cover 612. The operating member 610 is a sliding button 611. It can be understood that the operating mechanism 600 also includes a mounting seat 620. The mounting seat 620 is fixedly connected to the sliding assembly 400. A button channel is provided on the mounting seat 620. The sliding button 611 can be slidably inserted into the button channel. The button cover 612 is covered on the end of the sliding button 611 facing the toggle member 510. The button cover 612 is transmission-connected to the toggle member 510. Figure 9 , the second state of the operating mechanism 600 is a schematic diagram after pressing. By pressing the sliding button 611, the sliding button 611 slides and pushes the button cover 612 to slide until the toggle member 510 is driven to rotate, thereby causing the locking structure 500 to disengage from the stop structure 210, and the user can operate more conveniently, making the entire operating mechanism 600 compact in structure, the transmission method simple and effective, and able to directly convert the user's operation into a mechanical action; when the sliding button 611 is pressed, the button cover 612 is pushed to slide, thereby driving the toggle member 510 to rotate, thereby achieving the disengagement of the locking structure 500 from the stop structure 210, providing a safe locking and unlocking mechanism.

[0072] Specifically, refer to Figure 5 and Figure 6 In this embodiment, a limiting recess is provided in the key channel to limit the sliding stroke of the sliding key 611 and improve the stability of the transmission.

[0073] Refer to 6 and Figure 7 Specifically, in some embodiments of the present invention, the locking structure 500 also includes an elastic member 520, which is arranged between the sliding assembly 400 and the toggle member 510. The elastic member 520 is used to drive the toggle member 510 to move so that the locking portion 511 is plugged into and fitted with the stop structure 210.

[0074] With the above structure, when the operating mechanism 600 is in the first state, i.e., the stationary state, the locking portion 511 of the toggle member 510 engages with the stop structure 210 under the action of the elastic member 520, thereby locking the sliding assembly 400 (including the puncture needle 310) at a specific position within the housing 100, preventing the puncture needle 310 from accidentally moving. When sliding is required, the operating member 610 is driven to move, causing the operating mechanism 600 to switch to the second state, causing the toggle member 510 to deflect, the elastic member 520 to compress, and the locking portion 511 to disengage from the stop structure 210. The provision of the elastic member 520 provides a restoring force on the toggle member 510, thereby returning the operating member 610 to the first state. This achieves self-locking and eliminates the need for the user to perform an additional reset action after completing an operation, simplifying the operation process.

[0075] Specifically, refer to Figure 6 In an embodiment of the present invention, the locking portion 511 is located on one side of the toggle member 510, and the elastic member 520 is located on the other side opposite to the toggle member 510, wherein the locking portion 511 and the elastic member 520 are aligned with each other.

[0076] With the above structure, since the locking part 511 and the elastic member 520 are located on opposite sides of the toggle member 510, the forces they apply to the toggle member 510 can be balanced with each other on the central axis, which helps to maintain the stability of the toggle member 510 and the smoothness of operation; the alignment setting provides structural symmetry, and the force transmission path is more direct and simple. The elastic member 520 can directly apply force to the locking part 511 during the resetting process, ensuring that the locking part 511 can accurately return to the locked position, thereby improving the reliability of operation.

[0077] Of course, in some embodiments, the elastic member 520 may also be arranged in a staggered manner with the locking portion 511 so that the locking portion 511 can be restored to be inserted and engaged with the stop structure 210, which is not limited here.

[0078] It should be noted that, in this embodiment, the above-mentioned elastic member 520 is a spring, the rotational connection between the toggle member 510 and the sliding assembly 400 is a fulcrum, the toggle member 510 has a power arm and a resistance arm, the power arm is transmission-connected to the operating member 610, one side of the resistance arm is connected to the locking portion 511, and the other side of the resistance arm is provided with a mounting protrusion, the spring is installed on the other side of the resistance arm, one end of the spring is sleeved on the mounting protrusion, and the other end abuts against the sliding assembly 400.

[0079] Of course, in some embodiments, the elastic member 520 can also be arranged between the operating member 610 and the sliding assembly 400. When the elastic member 520 drives the operating member 610 to reset to the first state, the operating member 610 can drive the toggle member 510 to reset, so that the locking portion 511 returns to the plug-in fit with the stop structure 210; it can be understood that the elastic member 520 can not only be set as a cylindrical spring, but also as a tension spring or an elastic sheet, which is not limited here.

[0080] Specifically, refer to Figure 5 and Figure 6 In this embodiment, the resistance arm length of the toggle member 510 is greater than the power arm length, which can be logically interpreted as making the toggle member 510 a labor-intensive lever. Due to the characteristics of the labor-intensive lever, the long resistance arm means that even an inadvertent slight touch will not cause a large displacement of the toggle member 510, thereby reducing the possibility of misoperation; a larger force needs to be applied during operation, which can provide a more stable operating feel, allowing the operator to feel clearer feedback during operation; the movement speed of the toggle member 510 can be controlled to make the operation smoother and avoid the impact or over-adjustment that may be caused by rapid rotation.

[0081] Specifically, refer to Figure 6 and Figure 7 In this embodiment, a mounting position is provided on the button cover 612, and a connecting column 512 is provided on the toggle member 510. It can be understood that the connecting column 512 is located on one side of the power arm of the toggle member 510, and the connecting column 512 is arranged on the same side as the elastic member 520. The connecting column 512 is plugged into the mounting position to realize the transmission of the toggle member 510.

[0082] Of course, in other embodiments of the present invention, the above-mentioned operating member 610 can also be configured to be rotatable relative to the shell 100. By driving the operating member 610 to rotate, the toggle member 510 can also be driven to rotate. For example, a plurality of driving protrusions are provided at intervals on the operating member 610. When the operating member 610 is rotated, the driving protrusions rotate accordingly to align with the toggle member 510, driving the toggle member 510 to move. When the operating member 610 continues to be rotated, the driving protrusions and the toggle member 510 are misaligned, and the elastic member 520 drives the toggle member 510 to reset; or, in other embodiments of the present invention, the operating member 610 is an elastic plate body with elasticity, which is deformed by pressing the elastic plate body, so that the deformation to the elastic plate body can push the toggle member 510 to rotate. This is not limited here.

[0083] It is understandable that, referring to Figures 4 to 7 In some embodiments of the present invention, the stopping structure 210 includes a plurality of stopping portions 211 , and the locking structure 500 contacts and cooperates with any one of the plurality of stopping portions 211 to limit the sliding assembly 400 from sliding relative to the housing 100 .

[0084] With the above structure, it can be understood that the locking portion 511 on the toggle member 510 can be plugged into and matched with one of the stop portions 211, thereby locking the position of the sliding assembly 400. Due to the presence of multiple stop portions 211, the locking structure 500 can contact different stop portions 211, thereby achieving multiple different positions of the sliding assembly 400.

[0085] Specifically, refer to Figures 4 to 6 In this embodiment, the plurality of stop portions 211 are arranged at intervals, and the user can make precise adjustments according to the size of the intervals, and each stop portion 211 represents a precise position. Of course, in some embodiments, the plurality of stop portions 211 can be arranged continuously and connected, which is not limited here.

[0086] It is understandable that, referring to Figures 4 to 7 In some embodiments of the present invention, the operating mechanism 600, the stopping structure 210 and the locking structure 500 are each provided in two groups; the two groups of operating mechanisms 600 are respectively provided on opposite sides of the housing 100, and the two groups of operating mechanisms 600 are configured to be linked with the sliding assembly 400.

[0087] By adopting the above structure, the structural design of the uterine fibroid steam ablation puncture handle device of the present invention is that the operating parts 610 of the operating mechanism 600 need to be pressed simultaneously on both sides of the shell 100 before it can slide, preventing accidental touch during the operation from puncturing other non-treatment tissues or mistaken ablation. It can self-lock at any position to avoid changes in the puncture position to achieve the treatment effect, greatly improving safety.

[0088] Of course, in some other embodiments, it is not excluded to set the operating mechanism 600 as a group, which is not limited here.

[0089] It is understandable that, referring to Figures 4 to 7 In some embodiments of the present invention, the sliding assembly 400 includes a slider 410 and a support column 420. The slider 410 is slidably connected to the housing 100, and the slider 410 is fixedly connected to the puncture needle 310.
