DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Uterine fibroids are the most common benign tumors of the female genitalia and the most common tumors in the human body. They are formed by the proliferation of uterine smooth muscle tissue, with a small amount of fibrous connective tissue in between. They can be single or multiple. Depending on the size of the tumor and the location of growth, clinical symptoms often include menorrhagia, dysmenorrhea, leucorrhea, abdominal mass, infertility, anemia, etc. They are more common in women aged 30 to 50, most common in women aged 40 to 50, and rare in women under 20. Its incidence is difficult to calculate. According to autopsy data, about 20% of women over 35 have uterine fibroids. Because many patients are asymptomatic or the fibroids are very small, the incidence reported in clinical reports is much lower than the actual incidence.

[0038] The latest treatment equipment available is the new generation of uterine fibroid ablation device from Gynesonics, a women's healthcare company in California, USA. It can combine intrauterine ultrasound guidance with targeted radiofrequency ablation to treat symptomatic uterine fibroids, including uterine fibroids associated with heavy menstrual bleeding, using incision-free surgery. The system provides a breakthrough alternative to hysterectomy and myomectomy. On the one hand, it supports pregnant women to give birth through the cervix, thereby avoiding damage to the abdominal cavity and does not require general anesthesia. On the other hand, it can also treat most types of fibroids, including submucosal, intramural, transmural and subserosal fibroids.

[0039] The existing uterine fibroid ablation device is a diagnostic and treatment device that combines an ultrasonic handle with a radiofrequency puncture handle. The traditional radiofrequency puncture handle uses a combination of a puncture needle and an electrode needle in the puncture structure. The radiofrequency puncture handle uses a first sliding key and a second sliding key to push the electrode needle together. For example, the first sliding key pushes the puncture needle, and the second sliding key pushes the electrode needle to the target position and stops. If the fibroid tissue is only stuck by the needle, it is easy for the treatment electrode needle to slip, causing the ablation area to change and fail to reach the expected treatment area, and there is a risk of damaging surrounding tissues.

[0040] In addition to the electrode needles mentioned above, traditional radiofrequency ablation surgery also requires the patient to be attached with electrode sheets so that the two can form a circuit before treatment can be performed. Patients with metal implants in their bodies cannot receive treatment, which has certain limitations. Otherwise, there is a risk of burns. In addition, the combination of the puncture needle and the electrode needle increases the volume of the structure and increases the area of ​​the puncture wound.

[0041] Combine the following Figure 1-Figure 11 The present invention describes a uterine fibroid steam ablation puncture handle device, which is used to solve the problem that the puncture structure in the related technology has a sliding phenomenon, causing the expected ablation treatment area to change, and there is also a risk of causing damage to surrounding tissues, and there are certain limitations and the problem of increasing the puncture wound area.

[0042] It is understandable that, referring to Figures 1 to 7In an embodiment of the present invention, the present invention provides a uterine fibroid steam ablation puncture handle device, comprising a housing 100, a puncture catheter assembly 300, a sliding assembly 400 and an operating mechanism 600, wherein a stop structure 210 is fixedly disposed in the housing 100, and the puncture catheter assembly 300 comprises 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, the sliding assembly 400 is fixedly connected to the puncture needle 310, and a locking structure 500 is movably disposed 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 sliding mechanism 600 drives the sliding assembly 400 by sliding, and 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; 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.

[0043] In the uterine fibroid steam ablation puncture handle device provided by the present invention, the puncture needle 310 is located 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 member can slide relative to the shell 100 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.

[0044] 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 ablation treatment area and preventing damage to surrounding tissues.

[0045] 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.

[0046] It is understandable that, referring to Figure 1 and Figure 2 In some embodiments of the present invention, the housing 100 includes a handle upper shell 110 and a handle lower shell 120 connected to the handle upper shell 110. The handle upper shell 110 and the handle lower shell 120 can be connected by, for example, screws and nuts, snap connections, etc. In this embodiment, a sliding channel is formed between the handle upper shell 110 and the handle lower shell 120 to prevent the operating mechanism 600 from sliding.

[0047] 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 shell 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 stopping structure 210 to limit the sliding of the sliding assembly 400 relative to the shell 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 stopping structure 210.

[0048] 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 accidentally moving; when sliding is required, the operating member 610 is driven to move so that the operating mechanism 600 switches to the second state, so that the toggle member 510 deflects, and the locking portion 511 is out of contact with the stop structure 210. At this time, the operating mechanism 600 can be pushed to drive the sliding assembly 400 to slide to 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; through the simple driving of 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.

[0049] 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.

[0050] It can be understood that, in the present embodiment, the locking portion 511 and the stop structure 210 are plug-fitted; of course, in some embodiments, the locking portion 511 and the stop structure 210 can also be abutted, which is not limited here.

[0051] Specifically, refer to Figure 8 and Fig. 9 In some embodiments of the present invention, the operating member 610 is configured to be slidable, and 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, and the mounting seat 620 is fixedly connected to the sliding assembly 400. A button channel is provided on the mounting seat 620, and the sliding button 611 can be slidably inserted in the button channel. The button cover 612 is covered on the end of the sliding button 611 facing the toggle member 510, and the button cover 612 is transmission-connected to the toggle member 510. Fig. 9 , the second state of the operating mechanism 600 is a schematic diagram after being pressed. 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, and the transmission method is simple and effective, which can 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. 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.

[0052] 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 disposed between the sliding assembly 400 and the toggle member 510, and the elastic member 520 is used to drive the toggle member 510 to move so that the locking portion 511 is plugged into and matched with the stop structure 210.

[0053] With the above structure, when the operating mechanism 600 is in the first state, i.e., the static state, under the action of the elastic member 520, the locking portion 511 of the toggle member 510 is plugged 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 accidentally moving; when sliding is required, the operating member 610 is driven to move so that the operating mechanism 600 switches to the second state, so that the toggle member 510 deflects, the elastic member 520 is compressed, and the locking portion 511 is out of contact with the stop structure 210. The setting of the elastic member 520 can provide a restoring force for the toggle member 510, so that the operating member 610 is also reset to the first state, and self-locking is achieved. After completing an operation, the user does not need to perform additional reset actions, which simplifies the operation process.

[0054] Specifically, refer to Figure 6 In the 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.

[0055] With the above structure, since the locking portion 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 concise. The elastic member 520 can directly apply force to the locking portion 511 during the resetting process, ensuring that the locking portion 511 can accurately return to the locked position, thereby improving the reliability of operation.

[0056] 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 matched with the stop structure 210 , which is not limited here.

[0057] 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 a mounting protrusion is provided on the other side of the resistance arm. 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.

[0058] Of course, in some embodiments, the elastic member 520 may also be disposed 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 may drive the toggle member 510 to reset, so that the locking portion 511 returns to the state to be plugged into and fit with the stop structure 210. It can be understood that the elastic member 520 may not only be a cylindrical spring, but may also be a tension spring or an elastic sheet, which is not limited here.

[0059] 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 understood 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 greater 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.

[0060] 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 plug-in-matched with the mounting position to realize the transmission of the toggle member 510.

[0061] Of course, in other embodiments of the present invention, the 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 elastic plate body can push the toggle member 510 to rotate. This is not limited here.

[0062] 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 of the sliding assembly 400 relative to the housing 100 .

[0063] 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. Since there are multiple stop portions 211, the locking structure 500 can contact different stop portions 211, thereby achieving multiple different positions of the sliding assembly 400.

[0064] Specifically, refer to Figures 4 to 6 In this embodiment, the plurality of stoppers 211 are arranged at intervals, and the user can make precise adjustments according to the size of the intervals, and each stopper 211 represents a precise position. Of course, in some embodiments, the plurality of stoppers 211 can be arranged in a continuous connection, which is not limited here.

[0065] 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 all 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.

[0066] 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 down on both sides of the shell 100 at the same time before they can slide, thereby preventing accidental touching during the operation from causing puncture of other non-treatment tissues or accidental ablation. Any position can be self-locked to avoid changes in the puncture position to prevent the treatment effect from being achieved, thereby greatly improving safety.

[0067] Of course, in some other embodiments, it is not excluded to set the operating mechanism 600 as a group, which is not limited here.

[0068] 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.
