DETAILED DESCRIPTION

[0037] 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.

[0038] 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.

[0039] 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.

[0040] The existing uterine fibroid steam ablation handle device is a diagnostic and treatment device that combines an ultrasonic handle 100 and a puncture handle 200. However, the above-mentioned uterine fibroid steam ablation handle device has the following problems: the ultrasonic handle 100 and the puncture handle 200 are not tightly fitted, and the puncture angle deviation is prone to occur during use. When the handles are separated, their reliability is poor and they are easily pulled apart, and the overall service life is relatively short.

[0041] It is understandable that the ultrasound handle 100 is mainly used for diagnosis and display of the location of fibroids and can be used for about 50 times, while the puncture handle 200 is mainly used for treatment and is a consumable material for one-time use, so a structure that can be quickly locked and released is required.

[0042] Combine the following Figure 1-Figure 15 The present invention describes a uterine fibroid steam ablation handle device, which is used to solve the problems in the related art that the ultrasonic handle 100 and the puncture handle 200 of the ablation device are not tightly fitted, the puncture angle deviation is easy to occur during use, the reliability is poor when the handle is separated, it is easy to be pulled apart, and the service life is relatively short.

[0043] It is understandable that, referring to Figure 1 , Figure 2 , Figure 8 and Fig. 9 In an embodiment of the present invention, the present invention provides a uterine fibroid steam ablation handle device, comprising an ultrasonic handle 100, a puncture handle 200 and a locking release mechanism, wherein the locking release mechanism comprises a first locking structure 300, a second locking structure 400 and an unlocking structure 500 that is transmission-connected to the first locking structure 300, one of the ultrasonic handle 100 and the puncture handle 200 is movably provided with the first locking structure 300 and the unlocking structure 500, and the other of the ultrasonic handle 100 and the puncture handle 200 is fixedly provided with the second locking structure 400, and the first locking structure 300 and the second locking structure 400 are configured to be detachably connected and matched; The locking and releasing mechanism has a locking state and an unlocking state, and the unlocking structure 500 can drive the first locking structure 300 to move so as to switch between the locking state and the unlocking state; In the locked state, the first locking structure 300 is fixedly connected to the second locking structure 400, the ultrasonic handle 100 and the puncture handle 200 are attached to each other, and the relative positions of the two are locked; In the unlocked state, the first locking structure 300 is separated from the second locking structure 400 to release the locking of the ultrasonic handle 100 and the puncture handle 200 .

[0044] The uterine fibroid steam ablation handle device provided by the present invention is provided with a first locking structure 300, a second locking structure 400 and an unlocking structure 500. In the locked state, the fixed connection between the first locking structure 300 and the second locking structure 400 is conducive to ensuring a tight fit between the ultrasonic handle 100 and the puncture handle 200, and is conducive to locking the relative positions of the two. This design improves the overall stability and safety, so that during use, the ultrasonic handle 100 and the puncture handle 200 will not have accidental relative displacement, thereby ensuring the normal operation and service life of the device, which is safe and reliable.

[0045] In the unlocked state, the separation of the first locking structure 300 and the second locking structure 400 releases the locking of the ultrasonic handle 100 and the puncture handle 200, and the two can be relatively separated. This feature provides great convenience for maintenance, overhaul or replacement of parts, making the operation faster and more efficient, thereby improving the performance and operating experience of the overall device.

[0046] Specifically, refer to Figures 6 to 9 In some embodiments of the present invention, when the first locking structure 300 and the unlocking structure 500 are both provided on the ultrasonic handle 100; the first locking structure 300 is slidably provided on the ultrasonic handle 100, and the first locking structure 300 is provided with a pushing portion 311 and a first buckle portion 312, referring to Figure 2 and Figure 4 The second locking structure 400 is a second buckle portion fixedly disposed on the puncture handle 200, and the first buckle portion 312 and the second buckle portion correspond to each other and are buckled together; The unlocking structure 500 is transmission-connected to the pushing portion 311 to drive the first locking structure 300 to slide relative to the ultrasonic handle 100 .

[0047] With the above structure, the first locking structure 300 can slide on the ultrasonic handle 100. This design increases the flexibility of operation and makes the locking and unlocking process smoother. The setting of the pushing portion 311 and the first buckle portion 312 on the first locking structure 300 and the second buckle portion on the second locking structure 400 form an effective locking mechanism. The one-to-one buckling cooperation of the first buckle portion 312 and the second buckle portion ensures the stability and reliability during locking. The transmission connection between the unlocking structure 500 and the pushing portion 311 allows the user to easily drive the first locking structure 300 to slide on the ultrasonic handle 100 through the unlocking structure 500, thereby realizing the buckling or separation of the first buckle portion 312 and the second buckle portion. Through the action of the unlocking structure 500, the first locking structure 300 and the second locking structure 400 can be easily locked and unlocked, so that the ultrasonic handle 100 and the puncture handle 200 can be tightly fitted or easily separated as needed, which is convenient for maintenance, replacement or adjustment.

[0048] Of course, in other embodiments, when the first locking structure 300 and the unlocking structure 500 are both disposed on the puncture handle 200 , this is not limited here.

[0049] Specifically, refer to Figures 6 to 9In some embodiments of the present invention, the first locking structure 300 includes a locking unit 310 and a first elastic member 320. At least a portion of the locking unit 310 is slidably disposed outside the ultrasonic handle 100. The pushing portion 311 and the first buckle portion 312 are both disposed on the locking unit 310. The first elastic member 320 is disposed between the locking unit 310 and the ultrasonic handle 100. The first elastic member 320 is used to drive the locking unit 310 to reset to a position where the first buckle portion 312 is buckled with the second buckle portion.

[0050] With the above structure, part of the structure of the locking unit 310 can be slidably arranged on the outside of the ultrasonic handle 100. The above design enables the locking unit 310 to slide along the ultrasonic handle 100, thereby realizing the locking and unlocking functions; the pushing portion 311 and the first buckle portion 312 are both located on the locking unit 310. Such a layout enables the operation and buckling actions to be concentrated on one component, thereby simplifying the structure and operation process.

[0051] By operating the unlocking structure 500 on the pushing portion 311 , the user can easily slide the locking unit 310 to achieve the buckling or separation of the first buckle portion 312 and the second buckle portion without complicated operation steps.

[0052] The use of the first elastic member 320 enables the locking unit 310 to automatically reset to the initial buckling position after unlocking, ensuring the convenience of the next operation and the reliability of the connection. The restoring force provided by the first elastic member 320 ensures the stable buckling of the locking unit 310 and the second locking structure 400, reducing looseness caused by vibration or impact; the reset function of the first elastic member 320 reduces the risk of accidental unlocking of the component and improves the safety of the overall device.

[0053] In summary, the above design not only improves the convenience of operation, but also enhances the stability and security of the connection, while providing protection for the maintenance and long-term use of the device.

[0054] Of course, in some other embodiments, the first locking structure 300 may also adopt a rotatable connection between the locking unit 310 and the ultrasonic handle 100. For example, the locking unit 310 is rotatably connected to the ultrasonic handle 100. When buckling is required, the locking unit 310 is driven by the unlocking structure 500 to rotate until the first buckle portion 312 is disengaged from the second buckle portion. The first elastic member 320 may also drive the locking unit 310 to rotate and reset. This is not limited here.

[0055] Specifically, refer to Figures 5 to 9In some embodiments of the present invention, the ultrasonic handle 100 is provided with a receiving recess 110 for locking fit, and the receiving recess 110 is provided with an avoidance opening connected to the outside, wherein, among the first buckle portion 312, the pushing portion 311 and the first elastic member 320, at least the first buckle portion 312 is located in the receiving recess 110.

[0056] It can be understood that the setting of the accommodating recess 110 provides a locking and fitting space for the buckling of the first buckle portion 312 and the second buckle portion, that is, when the ultrasonic handle 100 and the puncture handle 200 are fitted, the second buckle portion can be moved through the avoidance opening to be located in the accommodating recess 110 and buckled with the first buckle portion 312; the accommodating recess 110 can protect the first buckle portion 312 from damage by the external environment; the accommodating recess 110 helps to accurately position the first buckle portion 312 and the second buckle portion, thereby improving the accuracy and reliability of the buckling, and the position of the accommodating recess 110 limits the movement range of the first buckle portion 312, thereby reducing the possibility of misoperation.

[0057] It should be noted that, in the present embodiment, a receiving recess 110 is formed at the bottom of the outer side wall of the ultrasonic handle 100, which can be understood as follows: the receiving recess 110 is located on the lower side of the ultrasonic handle 100 for fitting with the puncture handle 200; the first buckle 312 and the first elastic member 320 are both located in the receiving recess 110, one end of the first elastic member 320 abuts against the side wall of the receiving recess 110, and the other end of the first elastic member 320 abuts against the first buckle 312; the pushing portion 311 is located outside the receiving recess 110 and inside the ultrasonic handle 100, therefore, it can be understood that, in the present embodiment, the first elastic member 320 is a cylindrical spring, which is sleeved on the locking unit 310, and of course, in some other embodiments, the first elastic member 320 can also be set as an elastic sheet, or the first elastic member 320 can also be set as a tension spring, one end of the tension spring is connected to the ultrasonic handle 100, and the other end is connected to the locking unit 310, which is not limited here.

[0058] Specifically, refer to Figure 4 and Figure 6 In the present embodiment, both the first buckle portion 312 and the second buckle portion are configured as a raised structure, and the cross-sections of the two are L-shaped, and an interlocking structure is formed by overlapping the first buckle portion 312 and the second buckle portion; the first buckle portion 312 is provided with a first pushing surface which is arranged obliquely, and the second buckle portion is provided with a second pushing surface which is arranged obliquely, so that the second pushing surface pushes the first pushing surface, so that the first buckle portion 312 drives the locking unit 310 to slide, so that the upper side surface of the first buckle portion 312 cooperates with the lower side surface of the second buckle portion, thereby limiting the relative positions of the ultrasonic handle 100 and the puncture handle 200 up and down, so that the two remain in close contact.

[0059] Of course, in some other embodiments, the first buckle portion 312, the pushing portion 311 and the first elastic member 320 are all arranged in the accommodating recess 110; or only the first buckle portion 312 is located in the accommodating recess 110, and the first elastic member 320 is arranged outside the accommodating recess 110, that is, the first elastic member 320 can be arranged inside the ultrasonic handle 100, one end of the first elastic member 320 is connected to the ultrasonic handle 100, and the other end is connected to the locking unit 310, which is not limited here.

[0060] Specifically, refer to Figure 6 In some embodiments of the present invention, a limiting groove 111 is provided in the accommodating recess 110, and a limiting portion 313 is provided on the locking unit 310. The limiting groove 111 and the limiting portion 313 are slidably and plug-fitted to limit the sliding stroke of the locking unit 310.

[0061] Through the cooperation between the limit groove 111 and the limit part 313, the sliding distance of the locking unit 310 can be accurately controlled to ensure that it moves within a predetermined range, thereby ensuring the accuracy of locking or unlocking; since the sliding stroke is limited, maintenance personnel can more easily predict and control the position of components when checking or replacing components, which is convenient for maintenance operations; the limit design makes the operation smoother, and the user can get better hand feedback when operating the locking unit 310, thereby improving the user experience. It should be noted that in this embodiment, the limit part 313 is a boss.

[0062] It should be noted that, in the embodiment of the present invention, the first buckle portion 312 and the limiting portion 313 are respectively located on the upper and lower sides of the locking unit 310, and the first buckle portion 312 and the limiting portion 313 are respectively located on the upper and lower sides of one end of the first elastic member 320, i.e., the cylindrical spring. The positioning effect of the first buckle portion 312 and the limiting portion 313 on the cylindrical spring helps to ensure the precise operation of the entire structure, provides two-way support and stability, makes the entire structure more solid, and helps to make more efficient use of space, especially in designs with limited space, can reduce the overall size of the structure.

[0063] It is understandable that, referring to Figures 5 to 9 In an embodiment of the present invention, a portion of the first locking structure 300 is located inside the ultrasonic handle 100, and another portion is passed through the ultrasonic handle 100 and extends to an area where the ultrasonic handle 100 is connected to the outside world; wherein a first sealing structure is provided on the ultrasonic handle 100 corresponding to the first locking structure 300, and the first sealing structure is used to seal the fitting gap between the first locking structure 300 and the ultrasonic handle 100.

[0064] It can be understood that, in the embodiment of the present invention, a sliding through hole is further provided on the ultrasonic handle 100, and the sliding through hole is connected to a side wall of the accommodating recess 110. Therefore, the locking unit 310 slides with the accommodating recess 110 through the sliding through hole, and the first sealing structure seals the fitting gap between the sliding through hole and the locking unit 310. After the ultrasonic handle 100 and the puncture handle 200 are separated, the ultrasonic handle 100 plays a sealing role when cleaning to protect the internal components of the ultrasonic handle 100.

[0065] Specifically, refer to Figure 6 , Figure 8 and Fig. 9 In an embodiment of the present invention, the first sealing structure includes a first sealing ring 610 and a sealing pressure piece 620. The first sealing ring 610 is sleeved on the first locking structure 300. One side of the first sealing ring 610 abuts against the ultrasonic handle 100, and the other side abuts against the sealing pressure piece 620. The sealing pressure piece 620 is sleeved on the first locking structure 300, and the sealing pressure piece 620 is used to limit the relative position of the first sealing ring 610 and the ultrasonic handle 100.

[0066] It can be understood that, in the embodiment of the present invention, a first annular mounting groove is provided at a position corresponding to the sliding through hole on the ultrasonic handle 100, the first annular mounting groove is adapted to the first sealing ring 610, and the sealing pressing piece 620 is located on one side of the first annular mounting groove. With the above structure, the first sealing ring 610 is sleeved on the first locking structure 300, and when the ultrasonic handle 100 and the puncture handle 200 are locked or the ultrasonic handle 100 and the puncture handle 200 are separated, the first sealing ring 610 is located in the first annular mounting groove, and the position of the first sealing ring 610 in the first annular mounting groove is limited by the sealing pressing piece 620, thereby achieving stable sealing, compact structure, and good stability.

[0067] Specifically, refer to Figure 6 , Figure 8 and Fig. 9In an embodiment of the present invention, the locking unit 310 includes a combination latch 314 and a latch kit 315, and the latch kit 315 is fixedly connected to the combination latch 314, and the connection method is, for example, welding, one-piece molding or bolt connection; the combination latch 314 is penetrated through the first annular mounting groove, the sliding through hole and the accommodating recess 110 which are sequentially penetrated, and the latch kit 315 is protruded toward the unlocking structure 500 to form a pushing portion 311, and a locking block is provided at one end of the combination latch 314 away from the latch kit 315, and the locking block is formed with the above-mentioned first buckle portion 312 and the limiting portion 313. It can be understood that the pushing portion 311 is a pushing boss. In the present embodiment, the sealing pressure piece 620 and the first sealing ring 610 are both sleeved on the engaging pin 314. It should be noted that the sealing pressure piece 620 is fixedly connected to the engaging pin 314 by a connection method such as welding, one-piece molding or bolt connection. Of course, in some embodiments, the first sealing ring 610 is installed in the space formed by the sealing pressure piece 620 and the first annular mounting groove. The sealing pressure piece 620 can also be fixedly connected to the ultrasonic handle 100 by welding, bolt connection, etc., which is not limited here.

[0068] It should be noted that in the embodiment of the present invention, the material of the first sealing ring 610 is a flexible material. Of course, in some embodiments, the material of the first sealing ring 610 is a rigid material. It can be understood that it is generally recommended to use a material with better flexibility as the sealing ring material, such as a rubber sealing ring, because they can better adapt to vibration and displacement during movement and maintain the sealing effect. However, if the application requires a certain rigidity to maintain the seal or support structure, PTFE or other rigid materials can be selected for filling.

[0069] It is understandable that, referring to Figure 1 , Figure 2 , Figures 6 to 9 In an embodiment of the present invention, a rotating shaft 120 is rotatably provided on the ultrasonic handle 100, and the unlocking structure 500 includes an unlocking rod 510 and a driving member 520. The unlocking rod 510 is used to drive the rotating shaft 120 to rotate. The unlocking rod 510 is arranged outside the ultrasonic handle 100. The unlocking rod 510 is connected to the rotating shaft 120 in a transmission connection. The driving member 520 is fixedly connected to the rotating shaft 120. The driving member 520 is connected to the first locking structure 300 in a transmission connection, wherein the outer peripheral wall of the driving member 520 has at least two different distances to the rotation center line of the rotating shaft 120.

[0070] It can be understood that, in this embodiment, for ease of understanding, two different distances are taken as examples, one of which is the first distance and the other is the second distance, the first distance is greater than zero, and the second distance is zero. Therefore, the unlocking rod 510 rotates downward, causing the rotating shaft 120 to rotate counterclockwise, so that the driving member 520 follows the rotating shaft 120 to rotate to the first distance and gradually abuts against the pushing portion 311, gradually pushing the pushing portion 311 to slide, driving the locking unit 310 to slide as a whole, and the first elastic member 320 is compressed. When the first distance is directly abutted against the pushing portion 311, the ultrasonic handle 100 and the puncture handle 200 can be separated at this time; when the unlocking rod 510 rotates in the opposite direction, the rotating shaft 120 rotates along with it, and the driving member 520 and the pushing portion 311 are spaced or staggered. At this time, the pushing portion 311 cannot be driven to slide, and the first locking structure 300 is reset to a position that can be buckled or locked.

[0071] By adopting the above structure, the unlocking rod 510 drives the rotating shaft 120 to rotate to switch the distance and cooperate with the pushing part 311 of the first locking structure, so as to drive the first locking structure 300 to separate from the second locking structure 400, thereby releasing the ultrasonic handle 100 and the puncture handle 200. The structure is simple and easy to install and operate.

[0072] It should be noted that, in this embodiment, the ultrasonic handle 100 is provided with a mounting channel, and the rotating shaft 120 is rotatably disposed in the ultrasonic handle 100 and extends through the mounting channel to be tightly fitted and fixedly connected with the unlocking lever 510; the tight fitting and fixed connection between the unlocking lever 510 and the rotating shaft 120 is, for example, fixedly connected by welding, clamping or bolting, etc., which is not limited here. Alternatively, in some embodiments, the unlocking lever 510 and the rotating shaft 120 can also be integrally formed into a rod, which is not limited here.

[0073] Specifically, refer to Figure 6 and Figure 8 In the embodiment of the present invention, the driving member 520 is an eccentric cam fixedly connected to the rotating shaft 120 .

[0074] With the above structure, when the ultrasonic handle 100 and the puncture handle 200 are separated, the eccentric cam is used to convert the rotational motion into linear motion, thereby compressing the first elastic member 320, i.e., the cylindrical spring, so that the first locking structure 300 and the second locking structure 400 are separated, and the travel trajectory is stable.

[0075] It should be noted that, in this embodiment, the driving member 520 and the rotating shaft 120 may be fixedly connected by tight fitting, for example, by welding, clamping or bolting, etc., which is not limited here. Alternatively, in some embodiments, the driving member 520 and the rotating shaft 120 may be integrally formed, which is not limited here.

[0076] It is understandable that, referring to Figure 7 and Figure 8 In the embodiment of the present invention, the ultrasonic handle 100 is further provided with a second sealing structure 630, which is used to seal the matching gap between the rotating shaft 120 and the ultrasonic handle 100. With the above structure, after the ultrasonic handle 100 and the puncture handle 200 are separated, the ultrasonic handle 100 plays a sealing role during cleaning to protect the internal components of the ultrasonic handle 100.

[0077] Specifically, in this embodiment, the second sealing structure 630 is a second sealing ring sleeved on the rotating shaft 120, and the material of the second sealing ring is a flexible material. Of course, in some embodiments, the material of the second sealing ring is a rigid material. It can be understood that it is generally recommended to use a material with better flexibility as the sealing ring material, such as a rubber sealing ring, because they can better adapt to vibration and displacement during movement and maintain the sealing effect. However, if the application requires a certain rigidity to maintain the seal or support structure, PTFE or other rigid materials can be selected for filling.

[0078] It should be noted that, in this embodiment, a second annular mounting groove is provided on the rotating shaft 120 for assembling a second sealing ring, and the inner ring of the second sealing ring abuts against the wall of the second annular mounting groove, and the outer ring of the second sealing ring abuts against the inner wall of the mounting channel to achieve a fitting clearance between the sealing mounting channel and the rotating shaft 120.

[0079] It is understandable that, referring to Figure 6 , Figure 8 and Fig. 9 In the embodiment of the present invention, a reset structure 640 is further provided in the ultrasonic handle 100 . The reset structure 640 is connected to the rotating shaft 120 . The reset structure 640 is used to drive the rotating shaft 120 to reset.

[0080] With the above structure, when the ultrasonic handle 100 and the puncture handle 200 are separated, the reset structure 640 drives the rotating shaft 120 to reset, thereby resetting the unlocking structure 500 and the first locking structure 300, so as to facilitate the next use with another puncture handle 200.

[0081] It should be noted that, in the embodiment of the present invention, the reset structure 640 is a tension spring, one end of which is connected to the ultrasonic handle 100, and the other end is connected to the rotating shaft 120. It can be understood that the rotating shaft 120 is provided with a connecting boss, and the connecting boss is provided with a connecting through hole to facilitate the connection of the tension spring. Of course, in some embodiments, the reset structure 640 can also be set as a torsion spring, etc.; or in some embodiments, the reset structure 640 can also adopt an electric structure to drive its rotating shaft 120 to reset, which is not limited here.

[0082] It should be noted that, refer to Figure 7 and Figure 8 In this embodiment, the first locking structure 300, the second locking structure 400 and the unlocking structure 500 are all configured into two groups, and the three are matched one by one.

[0083] The two groups of first locking structures 300, the two groups of second locking structures 400 and the two groups of unlocking structures 500 are arranged at intervals. During operation, it is necessary to rotate the unlocking rods 510 of the two groups of unlocking structures 500 to release the fitting lock of the ultrasonic handle 100 and the puncture handle 200, thereby improving the locking performance.

[0084] Of course, in some embodiments, the first locking structure 300, the second locking structure 400 and the unlocking structure 500 can also be set as a group, or it can be understood that the unlocking structure 500 is set as a group, and the two groups of first locking structures 300 are transmission connected to the same group of unlocking structures 500, that is, one driving member 520 can be transmission-coordinated with the two groups of first locking structures 300 at the same time, which is not limited here.

[0085] It is understandable that, referring to Figures 1 to 3 In an embodiment of the present invention, the ultrasonic handle 100 includes a probe shaft 130, and the puncture handle 200 includes a puncture catheter assembly 260; the probe shaft 130 is provided with a first fitting structure 131, and the puncture catheter assembly 260 is provided with a second fitting structure 2631, and the first fitting structure 131 and the second fitting structure 2631 can be detachably fitted; wherein, when the first fitting structure 131 and the second fitting structure 2631 are fitted, they can cooperate with the first locking structure 300 and the second locking structure 400, so that the ultrasonic handle 100 and the puncture handle 200 are fitted and locked.

[0086] It can be understood that the distal end of the probe shaft 130 away from the operating end of the ultrasonic handle 100 is provided with a first fitting structure 131 , and correspondingly, the distal end of the puncture catheter assembly 260 is provided with a second fitting structure 2631 .

[0087] With the above structure, when the ultrasonic handle 100 and the puncture handle 200 are buckled together, the first fitting structure 131 cooperates with the second fitting structure 2631 and the first locking structure 300 and the second locking structure 400, which work together to make the buckle tighter and the mechanism safe and stable.

[0088] Specifically, refer to Figure 2 and Figure 3 In this embodiment, the first fitting structure 131 is configured as a fitting groove, and the second fitting structure 2631 is configured as a fitting protrusion. The design of the fitting groove and the fitting protrusion allows the ultrasonic handle 100 and the puncture handle 200 to be precisely aligned during assembly, and the structure is simple and easy to manufacture.

[0089] Of course, in some embodiments, the first fitting structure 131 can also be set as a fitting protrusion, and the second fitting structure 2631 can be set as a fitting groove, or the first fitting structure 131 and the second fitting structure 2631 can adopt a pin and socket matching method, which is not limited here.

[0090] Specifically, in this embodiment, the first fitting structure 131 and the second fitting structure 2631 are both V-shaped fitting structures.

[0091] It can be understood that, in the embodiment of the present invention, the general locking and releasing process of the ablation handle device is as follows: When the ultrasonic handle 100 and the puncture handle 200 are combined, the first fitting structure 131 and the second fitting structure 2631 fit together, and the first locking structure 300 and the second locking structure 400 are buckled together and are always in a buckled state under the action of the first elastic member 320. In this embodiment, it can be understood that the first locking structure 300 is a movable buckle, and the second locking structure 400 is a fixed buckle. The first locking structure 300 is always in a retractable state under the action of the first elastic member 320; When the unlocking rod 510 of the unlocking structure 500 rotates downward, the rotating shaft 120 rotates counterclockwise, so that the driving member 520 squeezes the pushing portion 311, causing the pushing portion 311 to slide away from the accommodating recess 110, driving the closing latch 314 to slide and the first elastic member 320 to be compressed. At this time, the ultrasonic handle 100 and the puncture handle 200 can be separated.

[0092] Reference Figure 8 In the embodiment of the present invention, the ultrasonic handle 100 further includes a probe upper shell 140 and a probe lower shell 150 connected to the probe upper shell 140. The probe upper shell 140 and the probe lower shell 150 can be connected by, for example, screws and nuts, snap connections, etc. In this embodiment, the probe lower shell 150 is provided with a receiving recess 110, the first locking structure 300 is provided on the probe lower shell 150, and the unlocking structure 500 and the rotating shaft 120 are both provided on the probe upper shell 140.

[0093] It is understandable that, referring to Figure 1 , Figure 4 , Figures 10 to 13In an embodiment of the present invention, the puncture handle 200 further includes a shell, a sliding assembly 270 and an operating mechanism 290. A stop structure 251 is fixedly provided in the shell. The puncture catheter assembly 260 includes a puncture needle 261, which is slidably provided in the shell and extends out of the shell; the sliding assembly 270 is slidably provided in the shell, the sliding assembly 270 is fixedly connected to the puncture needle 261, and a locking structure 280 is movably provided on the sliding assembly 270. The locking structure 280 is used to detachably contact and cooperate with the stop structure 251 to lock or unlock the sliding of the sliding assembly 270; the operating mechanism 290 is slidably provided in the shell, the operating mechanism 290 slides to drive the sliding assembly 270, the operating mechanism 290 is transmission-connected to the locking structure 280, and the operating mechanism 290 has a first state and a second state; In the first state, the locking structure 280 contacts and cooperates with the stopping structure 251 to limit the sliding of the sliding assembly 270; in the second state, the operating mechanism 290 drives the locking structure 280 to move to separate from the stopping structure 251 to release the restriction on the sliding of the sliding assembly 270; after the sliding assembly 270 slides to the target position, the operating mechanism 290 resets to the first state.

[0094] With the above structure, when the puncture needle 261 is located in the initial position and the operating mechanism 290 is in the first state, the locking structure 280 contacts and cooperates with the stop structure 251 to limit the sliding of the sliding assembly 270 relative to the shell, and then limits the sliding of the puncture needle 261; when sliding is required, the operating mechanism 290 is placed in the second state, and the locking structure 280 is driven by the operating mechanism 290 to move to separate from the stop structure 251 to release the restriction on the sliding assembly 270, so that the sliding member can slide relative to the shell to the target position; after sliding to the target position, the operating mechanism 290 is reset to the first state, and the locking structure 280 returns to contact and cooperate with the stop structure 251, and then locks the sliding assembly 270 and the puncture needle 261.

[0095] Therefore, it can be understood that through the cooperation between the sliding assembly 270, the operating mechanism 290, the stop structure 251 and the locking structure 280, the puncture needle 261 can be locked after being pushed to the target position, that is, self-locking, to avoid the puncture needle 261 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.

[0096] It should be noted that, in the embodiment of the present invention, the puncture needle 261 can slide toward the front end of the shell through the operating mechanism 290 and the sliding assembly 270 to perform diagnosis and treatment.

[0097] It is understandable that, referring to Figures 1 to 3In some embodiments of the present invention, the housing includes an upper handle shell 210 and a lower handle shell 220 connected to the upper handle shell 210. The upper handle shell 210 and the lower handle shell 220 may be connected by, for example, screws and nuts, snap connections, etc. In this embodiment, a sliding channel is formed between the upper handle shell 210 and the lower handle shell 220 to prevent the operating mechanism 290 from sliding.

[0098] It is understandable that, referring to Figures 10 to 13 In some embodiments of the present invention, the operating mechanism 290 includes an operating member 291 that can move relative to the shell; the locking structure 280 includes a toggle member 281, which is rotatably connected to the sliding assembly 270, and a locking portion 2811 is provided on the toggle member 281, which is used to plug and cooperate with the stop structure 251 to limit the sliding assembly 270 from sliding relative to the shell; wherein the operating member 291 is transmission-connected to the toggle member 281, and the locking portion 2811 can rotate with the toggle member 281 until it is separated from the stop structure 251.

[0099] With the above structure, when the operating mechanism 290 is in the first state, that is, the natural static state, the locking portion 2811 of the toggle member 281 is plugged into and matched with the stop structure 251 to achieve locking, and the sliding assembly 270 (including the puncture needle 261) is fixed at a specific position of the shell to prevent the puncture needle 261 from moving accidentally; when sliding is required, the operating member 291 is driven to move so that the operating mechanism 290 switches to the second state, so that the toggle member 281 deflects, and the locking portion 2811 is out of contact with the stop structure 251. At this time, the sliding assembly 270 can be driven to slide toward the front end of the shell to the target position by pushing the operating mechanism 290, so that the front end of the puncture needle 261 also slides to the target position, and the sliding positions of the sliding assembly 270 and the puncture needle 261 are accurately controlled; through the simple driving of the operating member 291, the user can easily achieve locking and unlocking, the operation is intuitive and convenient, and the device structure can be made compact.

[0100] Of course, in some embodiments, the toggle member 281 can also be configured to be slidably connected to the sliding assembly 270, and the locking structure 280 and the stop structure 251 can be plugged in or separated by sliding the toggle member 281, which is not limited here; or the toggle member 281 can also be configured to be a retractable structure, which is not limited here.

[0101] It can be understood that, in the present embodiment, the locking portion 2811 and the stop structure 251 are plug-fitted; of course, in some embodiments, the locking portion 2811 and the stop structure 251 can also be abutted, which is not limited here.

[0102] Specifically, refer to Figures 10 to 13In some embodiments of the present invention, the operating member 291 is configured to be slidable, and the operating member 291 includes a sliding button 2911 and a button cover 2912. The operating member 291 is a sliding button 2911. It can be understood that the operating mechanism 290 also includes a mounting seat 292, and the mounting seat 292 is fixedly connected to the sliding assembly 270. A button channel is provided on the mounting seat 292. The sliding button 2911 can be slidably inserted in the button channel. The button cover 2912 is covered on the end of the sliding button 2911 facing the toggle member 281, and the button cover 2912 is transmission-connected to the toggle member 281. Referring to the figure, the second state of the operating mechanism 290 is a schematic diagram after pressing. By pressing the sliding button 2911, the sliding button 2911 slides and pushes the button cover 2912 to slide to drive the toggle member 281 to rotate, thereby causing the locking structure 280 to disengage from the stop structure 251, and the user can operate more conveniently, so that the entire operating mechanism 290 has a compact structure, a simple and effective transmission method, and can directly convert the user's operation into a mechanical action; when the sliding button 2911 is pressed, the button cover 2912 is pushed to slide, thereby driving the toggle member 281 to rotate, thereby achieving the disengagement of the locking structure 280 from the stop structure 251, and providing a safe locking and unlocking mechanism.

[0103] Specifically, in this embodiment, a limiting recess is provided in the key channel to limit the sliding stroke of the sliding key 2911 and improve the stability of the transmission.

[0104] Reference Fig.12 and Fig.13 Specifically, in some embodiments of the present invention, the locking structure 280 also includes a second elastic member 282, which is disposed between the sliding assembly 270 and the toggle member 281, and the second elastic member 282 is used to drive the toggle member 281 to move so that the locking portion 2811 is plugged into and matched with the stop structure 251.

[0105] With the above structure, when the operating mechanism 290 is in the first state, i.e., the static state, under the action of the second elastic member 282, the locking portion 2811 of the toggle member 281 is plugged and matched with the stop structure 251 to achieve locking, and the sliding assembly 270 (including the puncture needle 261) is fixed at a specific position of the housing to prevent the puncture needle 261 from accidentally moving; when sliding is required, the operating member 291 is driven to move so that the operating mechanism 290 switches to the second state, so that the toggle member 281 deflects, the second elastic member 282 is compressed, and the locking portion 2811 is out of contact with the stop structure 251. The second elastic member 282 is provided to provide a restoring force for the toggle member 281, so that the operating member 291 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.

[0106] Specifically, refer to Fig.12 In the embodiment of the present invention, the locking portion 2811 is located on one side of the toggle member 281, and the second elastic member 282 is located on the other side opposite to the toggle member 281, wherein the locking portion 2811 and the second elastic member 282 are aligned with each other.

[0107] With the above structure, since the locking portion 2811 and the second elastic member 282 are located on opposite sides of the toggle member 281, the forces they apply to the toggle member 281 can be balanced with each other on the central axis, which helps to maintain the stability of the toggle member 281 and the smoothness of operation; the alignment setting provides structural symmetry, and the force transmission path is more direct and concise. The second elastic member 282 can directly apply force to the locking portion 2811 during the resetting process, ensuring that the locking portion 2811 can accurately return to the locked position, thereby improving the reliability of operation.

[0108] Of course, in some embodiments, the second elastic member 282 may also be arranged in a staggered manner with the locking portion 2811 , so that the locking portion 2811 can be restored to be inserted and matched with the stop structure 251 , which is not limited here.

[0109] It should be noted that, in this embodiment, the above-mentioned second elastic member 282 is a spring, the rotational connection between the toggle member 281 and the sliding assembly 270 is a fulcrum, the toggle member 281 has a power arm and a resistance arm, the power arm is transmission-connected to the operating member 291, one side of the resistance arm is connected to the locking portion 2811, 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 270.

[0110] Of course, in some embodiments, the second elastic member 282 may also be disposed between the operating member 291 and the sliding assembly 270. When the second elastic member 282 drives the operating member 291 to reset to the first state, the operating member 291 may drive the toggle member 281 to reset, so that the locking portion 2811 returns to the plug-in fit with the stop structure 251. It can be understood that the second elastic member 282 may not only be a cylindrical spring, but may also be a tension spring or an elastic sheet, which is not limited here.

[0111] Specifically, refer to Fig.12In this embodiment, the resistance arm length of the toggle member 281 is greater than the power arm length, which can be logically understood as making the toggle member 281 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 281, 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 281 can be controlled to make the operation smoother and avoid the impact or over-adjustment that may be caused by rapid rotation.

[0112] Specifically, refer to Fig.12 and Fig.13 In this embodiment, a mounting position is provided on the button cover 2912, and a connecting column 2812 is provided on the toggle member 281. It can be understood that the connecting column 2812 is located on one side of the power arm of the toggle member 281, and the connecting column 2812 is arranged on the same side as the second elastic member 282. The connecting column 2812 is plug-in-matched with the mounting position to realize the transmission of the toggle member 281.

[0113] Of course, in some other embodiments of the present invention, the above-mentioned operating member 291 can also be configured to be rotatable relative to the shell. By driving the operating member 291 to rotate, the toggle member 281 can also be driven to rotate. For example, a plurality of driving protrusions are arranged at intervals on the operating member 291. When the operating member 291 is rotated, the driving protrusion rotates accordingly to align with the toggle member 281, driving the toggle member 281 to move. When the operating member 291 continues to be rotated, the driving protrusion and the toggle member 281 are misaligned, and the second elastic member 282 drives the toggle member 281 to reset; or, in some other embodiments of the present invention, the operating member 291 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 281 to rotate, which is not limited here.

[0114] It is understandable that, referring to Figures 10 to 13 In some embodiments of the present invention, the stopping structure 251 includes a plurality of stopping portions 2511, and the locking structure 280 contacts and cooperates with any one of the plurality of stopping portions 2511 to limit the sliding of the sliding assembly 270 relative to the housing.

[0115] With the above structure, it can be understood that the locking portion 2811 on the toggle member 281 can be plugged into and matched with one of the stop portions 2511, thereby locking the position of the sliding assembly 270. Since there are multiple stop portions 2511, the locking structure 280 can contact different stop portions 2511, thereby achieving multiple different positions of the sliding assembly 270.

[0116] Specifically, refer to Figures 10 to 13In this embodiment, the plurality of stoppers 2511 are arranged at intervals, and the user can make precise adjustments according to the size of the intervals, and each stopper 2511 represents a precise position. Of course, in some embodiments, the plurality of stoppers 2511 can be arranged in a continuous connection, which is not limited here.

[0117] It is understandable that, referring to Figures 10 to 13 In some embodiments of the present invention, the operating mechanism 290, the stopping structure 251 and the locking structure 280 are all provided in two groups; the two groups of operating mechanisms 290 are respectively provided on opposite sides of the shell, and the two groups of operating mechanisms 290 are configured to be linked with the sliding assembly 270.

[0118] By adopting the above structure, the structural design of the puncture handle 200 of the present invention is that the operating parts 291 of the operating mechanism 290 need to be pressed down simultaneously on both sides of the shell to slide, thereby preventing accidental touch during the operation from puncturing other non-treatment tissues or mistaken ablation. Any position can be self-locked to avoid the change of puncture position to prevent the treatment effect from being achieved, thereby greatly improving safety.

[0119] Of course, in some other embodiments, it is not excluded to set the operating mechanism 290 as a group, which is not limited here.
