Detailed Implementation

[0058] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0059] Uterine fibroids (myomas of uterus) are the most common benign tumors of the female reproductive system and also the most common tumors in the human body. They are formed by the proliferation of uterine smooth muscle tissue, interspersed with a small amount of fibrous connective tissue. They can be single or multiple. Depending on the size and location of the tumor, clinical symptoms often include menorrhagia, dysmenorrhea, leukorrhea, abdominal mass, infertility, and anemia. They are most common in women aged 30-50, with the highest incidence between 40 and 50 years old, and are rare in women under 20. Their incidence is difficult to statistically determine; according to autopsy data, approximately 20% of women over 35 years of age have uterine fibroids. Because many patients are asymptomatic or have very small fibroids, the clinically reported incidence is far lower than the true incidence.

[0060] A state-of-the-art treatment device from Gynesonics, a women's healthcare company in California, USA, combines intrauterine ultrasound guidance with targeted radiofrequency ablation to treat symptomatic uterine fibroids, including those associated with heavy menstrual bleeding, using a non-invasive procedure. This system offers a breakthrough alternative to hysterectomy and myomectomy. On one hand, it supports cervical delivery, avoiding damage to the abdominal cavity and eliminating the need for general anesthesia. On the other hand, it can treat most types of fibroids, including submucosal, intramural, transmural, and subserosal fibroids.

[0061] The existing uterine fibroid steam ablation handpiece device is a diagnostic and treatment device that combines an ultrasonic handpiece 100 and a puncture handpiece 200. However, the above-mentioned uterine fibroid steam ablation handpiece device has the following problems: the ultrasonic handpiece 100 and the puncture handpiece 200 do not fit tightly, and the puncture angle is prone to deviation during use. When the handpiece is separated, its reliability is not good and it is easy to break. The overall service life is relatively short.

[0062] Understandably, the ultrasound handpiece 100 is mainly used for diagnosis to show the location of fibroids and can be used about 50 times, while the puncture handpiece 200 is mainly used for treatment and is a consumable for single use. Therefore, a structure is needed that can lock and release quickly.

[0063] The following description, in conjunction with Figures 1-16, describes a steam ablation handle device for uterine fibroids according to the present invention, which solves the problems in related technologies where the ultrasonic handle 100 and the puncture handle 200 of the ablation device do not fit tightly, resulting in easy deviation of the puncture angle during use, poor reliability when the handle is separated, easy breakage, and relatively short service life.

[0064] It is understood that, referring to Figures 1, 2, 8, and 9, in this embodiment of the invention, the present invention provides a steam ablation handle device for uterine fibroids, including an ultrasonic handle 100, a puncture handle 200, and a locking and releasing mechanism. The locking and releasing mechanism includes a first locking structure 300, a second locking structure 400, and an unlocking structure 500 that is pulsatorically 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. The first locking structure 300 and the second locking structure 400 are configured to be detachably connected and engaged.

[0065] The locking and releasing mechanism has a locked state and an unlocked state. The unlocking structure 500 can drive the first locking structure 300 to move so as to switch between the locked state and the unlocked state.

[0066] In the locked state, the first locking structure 300 and the second locking structure 400 are fixedly connected, the ultrasonic handle 100 and the puncture handle 200 are in contact with each other, and their relative positions are locked.

[0067] In the unlocked state, the first locking structure 300 separates from the second locking structure 400 to release the locking of the ultrasound handle 100 and the puncture handle 200.

[0068] The uterine fibroid steam ablation handle device provided by the present invention, by providing 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 helps to ensure a tight fit between the ultrasonic handle 100 and the puncture handle 200, and helps to lock their relative positions. This design improves the overall stability and safety, so that the ultrasonic handle 100 and the puncture handle 200 will not undergo accidental relative displacement during use, thereby ensuring the normal operation and service life of the device, and making it safe and reliable.

[0069] 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, allowing them to separate relative to each other. This feature greatly facilitates maintenance, repair, or replacement of parts, making operation faster and more efficient, thereby improving the overall performance of the device and the user experience.

[0070] Specifically, referring to Figures 6 to 9, in some embodiments of the present invention, when both the first locking structure 300 and the unlocking structure 500 are 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 part 311 and a first buckle part 312. Referring to Figures 2 and 4, the second locking structure 400 is a second buckle part fixedly provided on the puncture handle 200, and the first buckle part 312 and the second buckle part correspond one-to-one and are fastened together.

[0071] The unlocking structure 500 is connected to the pushing part 311 to drive the first locking structure 300 to slide relative to the ultrasonic handle 100.

[0072] With the above structure, the first locking structure 300 can slide on the ultrasonic handle 100, which increases the flexibility of operation and makes the locking and unlocking process smoother. The push part 311 and the first buckle 312 on the first locking structure 300, and the second buckle on the second locking structure 400, form an effective locking mechanism. The one-to-one engagement of the first buckle 312 and the second buckle ensures the stability and reliability of locking. The transmission connection between the unlocking structure 500 and the push part 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 engagement or disengagement of the first buckle 312 and the second buckle. Through the function of the unlocking structure 500, the locking and unlocking of the first locking structure 300 and the second locking structure 400 can be easily realized, 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.

[0073] Of course, in some other embodiments, both the first locking structure 300 and the unlocking structure 500 are provided on the piercing handle 200, which is not limited here.

[0074] Specifically, referring to Figures 6 to 9, in some embodiments of the present invention, the first locking structure 300 includes a locking unit 310 and a first elastic member 320. The locking unit 310 is at least partially slidably disposed outside the ultrasonic handle 100. The pushing part 311 and the first buckle part 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 the position where the first buckle part 312 and the second buckle part are engaged.

[0075] With the above structure, part of the locking unit 310 is slidably disposed on the outside of the ultrasonic handle 100. The above design allows the locking unit 310 to slide along the ultrasonic handle 100, thereby realizing the locking and unlocking functions. The pushing part 311 and the first buckling part 312 are both located on the locking unit 310. This layout concentrates the operation and buckling actions on one component, simplifying the structure and operation process.

[0076] By operating the push part 311 through the unlocking structure 500, the user can easily slide the locking unit 310 to achieve the engagement or disengagement of the first buckle 312 and the second buckle without complicated operating steps.

[0077] The use of the first elastic element 320 enables the locking unit 310 to automatically reset to the initial latching position after unlocking, ensuring the convenience of the next operation and the reliability of the connection. The restoring force provided by the first elastic element 320 ensures the stable latching of the locking unit 310 and the second locking structure 400, reducing loosening caused by vibration or impact. The reset function of the first elastic element 320 reduces the risk of accidental unlocking of components and improves the safety of the overall device.

[0078] In summary, the above design not only improves the ease of operation but also enhances the stability and security of the connection, while providing a guarantee for the maintenance and long-term use of the device.

[0079] Of course, in some other embodiments, the first locking structure 300 described above can also be rotatably connected to the ultrasonic handle 100 via the locking unit 310. For example, the locking unit 310 is rotatably connected to the ultrasonic handle 100. When it is necessary to fasten, the locking unit 310 is driven to rotate through the unlocking structure 500 until the first fastening part 312 and the second fastening part are disengaged. The first elastic member 320 can also drive the locking unit 310 to rotate and reset. This is not limited here.

[0080] Specifically, referring to Figures 5 to 9, in some embodiments of the present invention, the ultrasonic handle 100 is provided with a receiving recess 110 for locking and engaging, and the receiving recess 110 is provided with an opening for communicating with the outside. Among the first buckle 312, the pushing part 311 and the first elastic member 320, at least the first buckle 312 is located in the receiving recess 110.

[0081] It can be understood that the setting of the receiving recess 110 provides a locking space for the first buckle 312 and the second buckle to be fastened together. That is, when the ultrasonic handle 100 and the puncture handle 200 are in contact, the second buckle can move through the avoidance opening to be located in the receiving recess 110 and fasten with the first buckle 312. The receiving recess 110 can protect the first buckle 312 from damage by the external environment. The receiving recess 110 helps to accurately position the first buckle 312 and the second buckle, improving the accuracy and reliability of the fastening. The position of the receiving recess 110 restricts the range of motion of the first buckle 312 and reduces the possibility of misoperation.

[0082] It should be noted that in this embodiment, a receiving recess 110 is formed at the bottom of the outer wall of the ultrasonic handle 100. This can be understood as the receiving recess 110 being 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 within 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 part 311 is located outside the receiving recess 110 and inside the ultrasonic handle 100. Therefore, it can be understood that in this embodiment, the first elastic member 320 is a cylindrical spring, which is sleeved on the locking unit 310. Of course, in other embodiments, the first elastic member 320 can also be an elastic sheet, or the first elastic member 320 can also be a tension spring, with one end of the tension spring connected to the ultrasonic handle 100 and the other end connected to the locking unit 310. This is not limited here.

[0083] Specifically, referring to Figures 4 and 6, in this embodiment, both the first buckle 312 and the second buckle are designed as protruding structures, and their cross-sections are L-shaped. The first buckle 312 and the second buckle overlap to form an interlocking structure. The first buckle 312 is provided with a first pressing surface that is inclined, and the second buckle is provided with a second pressing surface that is inclined, so that the second pressing surface pushes against the first pressing surface, so that the first buckle 312 drives the locking unit 310 to slide, so that the upper side of the first buckle 312 cooperates with the lower side of the second buckle, thereby limiting the relative vertical position of the ultrasonic handle 100 and the puncture handle 200, so that the two remain in close contact.

[0084] Of course, in some other embodiments, the first buckle 312, the pusher 311 and the first elastic member 320 are all located in the receiving recess 110; or only the first buckle 312 is located in the receiving recess 110 and the first elastic member 320 is located outside the receiving recess 110, that is, the first elastic member 320 can be located inside the ultrasonic handle 100, with one end of the first elastic member 320 connected to the ultrasonic handle 100 and the other end connected to the locking unit 310, which is not limited here.

[0085] Specifically, referring to FIG6, in some embodiments of the present invention, a limiting groove 111 is provided in the receiving recess 110, and a limiting part 313 is provided on the locking unit 310. The limiting groove 111 and the limiting part 313 slide and are inserted into each other to limit the sliding stroke of the locking unit 310.

[0086] By cooperating with the limiting groove 111 and the limiting part 313, the sliding distance of the locking unit 310 can be precisely controlled, ensuring that it moves within a predetermined range, thereby guaranteeing the accuracy of locking or unlocking. Because the sliding stroke is limited, maintenance personnel can more easily predict and control the position of components when inspecting or replacing them, facilitating maintenance operations. The limiting design makes operation smoother, providing users with better tactile feedback when operating the locking unit 310, thus improving the user experience. It should be noted that in this embodiment, the limiting part 313 is a boss.

[0087] It should be noted that, in this embodiment of the invention, the first buckle 312 and the limiting part 313 are located on opposite upper and lower sides of the locking unit 310, respectively. The first buckle 312 and the limiting part 313 are located on the upper and lower sides of one end of the first elastic member 320, i.e., the cylindrical spring. The positioning function of the first buckle 312 and the limiting part 313 on the cylindrical spring helps to ensure the precise operation of the entire structure, provides bidirectional support and stability, makes the entire structure more robust, and helps to make more effective use of space. Especially in space-constrained designs, it can reduce the overall size of the structure.

[0088] It is understood that, referring to Figures 5 to 9, in this embodiment of the invention, a portion of the first locking structure 300 is located inside the ultrasonic handle 100, and another portion passes through the ultrasonic handle 100 and extends to the area where the ultrasonic handle 100 communicates with the outside; 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 mating gap between the first locking structure 300 and the ultrasonic handle 100.

[0089] It can be understood that, in this embodiment of the invention, the ultrasonic handle 100 is also provided with a sliding through hole, which is connected to one side wall of the receiving recess 110. Therefore, the locking unit 310 slides with the receiving recess 110 through the sliding through hole, while 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 it is cleaned, protecting the internal components of the ultrasonic handle 100.

[0090] Specifically, referring to Figures 6, 8, and 9, in this embodiment of the invention, the first sealing structure includes a first sealing ring 610 and a sealing pressure member 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 member 620. The sealing pressure member 620 is sleeved on the first locking structure 300 and is used to limit the relative position of the first sealing ring 610 and the ultrasonic handle 100.

[0091] In this embodiment of the invention, the ultrasonic handle 100 has a first annular mounting groove corresponding to the sliding through hole. The first annular mounting groove is adapted to the first sealing ring 610, and the sealing pressure member 620 is located on one side of the first annular mounting groove. With this structure, the first sealing ring 610 is fitted onto the first locking structure 300. When the ultrasonic handle 100 and the puncture handle 200 are locked or separated, the first sealing ring 610 is located within the first annular mounting groove. The sealing pressure member 620 restricts the position of the first sealing ring 610 within the first annular mounting groove, thereby achieving a stable seal. The structure is compact and has good stability.

[0092] Specifically, referring to Figures 6, 8, and 9, in this embodiment of the invention, the locking unit 310 includes a composite pin 314 and a pin assembly 315. The pin assembly 315 is fixedly connected to the composite pin 314, and the connection method is, for example, welding, integral molding, or bolt connection. The composite pin 314 passes through a first annular mounting groove, a sliding through hole, and a receiving recess 110 in sequence. The pin assembly 315 protrudes towards the unlocking structure 500 to form a pushing part 311. A locking block is provided at one end of the composite pin 314 away from the pin assembly 315. The locking block forms the aforementioned first buckle part 312 and limiting part 313. It can be understood that the pushing part 311 is a pushing boss. In this embodiment, the sealing pressure member 620 and the first sealing ring 610 are both sleeved on the assembly pin 314. It should be noted that the sealing pressure member 620 and the assembly pin 314 are fixedly connected. The connection method is, for example, welding, integral molding or bolt connection. Of course, in some embodiments, the first sealing ring 610 is installed in the space formed by the sealing pressure member 620 and the first annular mounting groove. The sealing pressure member 620 can also be fixedly connected to the ultrasonic handle 100 by welding, bolt connection or other methods. This is not limited here.

[0093] It should be noted that in this embodiment of the invention, the first sealing ring 610 is made of a flexible material. However, in some embodiments, the first sealing ring 610 is made of a rigid material. It can be understood that materials with good flexibility, such as rubber sealing rings, are generally recommended for use as sealing ring materials because they can better adapt to vibrations and displacements during movement and maintain a sealing effect. However, if the application requires a certain degree of rigidity to maintain the seal or support the structure, PTFE or other rigid materials can be selected as fillers.

[0094] It is understood that, referring to Figures 1, 2, 6 to 9, in this embodiment of the invention, the ultrasonic handle 100 is rotatably provided with a rotating shaft 120, 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 located outside the ultrasonic handle 100 and is connected to the rotating shaft 120 in a transmission manner. The driving member 520 is fixedly connected to the rotating shaft 120 and is connected to the first locking structure 300 in a transmission manner. The outer peripheral wall of the driving member 520 has at least two different distances from the rotation center line of the rotating shaft 120.

[0095] In this embodiment, for ease of understanding, two different distances are used as examples, one being the first distance and the other the second distance. The first distance is greater than zero, and the second distance is zero. Therefore, when the unlocking rod 510 rotates downward, the rotating shaft 120 rotates counterclockwise, causing the driving member 520 to rotate with the rotating shaft 120 until the first distance gradually comes into contact with the pushing part 311. During this process, the driving part 311 is gradually pushed to slide, causing the locking unit 310 to slide as a whole. The first elastic member 320 is compressed. When the first distance comes into contact with the pushing part 311, the ultrasonic handle 100 and the puncture handle 200 can be separated. When the unlocking rod 510 rotates in the opposite direction, the rotating shaft 120 rotates with it. The driving member 520 and the pushing part 311 are spaced apart or misaligned. At this time, the pushing part 311 cannot be driven to slide, and the first locking structure 300 is reset and is in a position where it can be fastened or locked.

[0096] With the above structure, the rotating shaft 120 is driven to rotate by the unlocking rod 510 to switch the distance and cooperate with the pushing part 311 of the first locking structure, thereby driving 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, easy to install and operate.

[0097] It should be noted that, in this embodiment, the ultrasonic handle 100 is provided with an installation channel, and the rotating shaft 120 is rotatably disposed within the ultrasonic handle 100 and extends through the installation channel to be tightly fitted and fixedly connected to the unlocking rod 510; the tight-fitting and fixed connection between the unlocking rod 510 and the rotating shaft 120 can be fixedly connected by means of welding, snap-fitting, or bolting, etc., and is not limited here. Alternatively, in some embodiments, the unlocking rod 510 and the rotating shaft 120 can be integrally formed into a single rod, and is not limited here.

[0098] Specifically, referring to Figures 6 and 8, in this embodiment of the invention, the driving member 520 is an eccentric cam fixedly connected to the rotating shaft 120.

[0099] With the above structure, when the ultrasonic handle 100 and the puncture handle 200 are separated, the rotational motion is converted into linear motion by using an eccentric cam, thereby compressing the first elastic element 320, i.e., the cylindrical spring, so that the first locking structure 300 and the second locking structure 400 are separated and the stroke trajectory is stable.

[0100] It should be noted that, in this embodiment, the drive component 520 and the rotating shaft 120 can be fixedly connected by a tight fit, such as by welding, snap-fitting, or bolting, and this is not limited thereto. Alternatively, in some embodiments, the drive component 520 and the rotating shaft 120 can be integrally formed, and this is not limited thereto.

[0101] It is understood that, referring to Figures 7 and 8, in this embodiment of the invention, the ultrasonic handle 100 is further provided with a second sealing structure 630, which is used to seal the mating 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 acts as a seal during cleaning, protecting the internal components of the ultrasonic handle 100.

[0102] Specifically, in this embodiment, the second sealing structure 630 is a second sealing ring sleeved on the rotating shaft 120. The second sealing ring is made of a flexible material. Of course, in some embodiments, the second sealing ring is made of a rigid material. It can be understood that it is generally recommended to use materials with good flexibility as the sealing ring material, such as rubber sealing rings, because they can better adapt to vibration and displacement during movement and maintain the sealing effect. However, if the application requires a certain degree of rigidity to maintain the seal or support the structure, PTFE or other rigid materials can be selected for filling.

[0103] It should be noted that, in this embodiment, the rotating shaft 120 is provided with a second annular mounting groove for assembling the 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, so as to achieve sealing of the fitting gap between the mounting channel and the rotating shaft 120.

[0104] It is understood that, referring to Figures 6, 8 and 9, in this embodiment of the invention, the ultrasonic handle 100 is further provided with a reset structure 640, which is connected to the rotating shaft 120 and is used to drive the rotating shaft 120 to reset.

[0105] With the above structure, when the ultrasound handle 100 and the puncture handle 200 are separated, the rotating shaft 120 is reset by the reset structure 640, thereby resetting the unlocking structure 500 and the first locking structure 300, so that it can be used in conjunction with another puncture handle 200 next time.

[0106] It should be noted that, in this embodiment of the invention, the reset structure 640 is a tension spring. One end of the tension spring is connected to the ultrasonic handle 100, and the other end is connected to the rotating shaft 120. This can be understood as the rotating shaft 120 having a connecting boss 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 a torsion spring, or in some embodiments, the reset structure 640 can also be an electric structure to drive its rotating shaft 120 to reset; this is not limited here.

[0107] It should be noted that, referring to Figures 7 and 8, in this embodiment, the first locking structure 300, the second locking structure 400, and the unlocking structure 500 are all configured as two sets, and the three are matched one-to-one.

[0108] The two sets of first locking structures 300, the two sets of second locking structures 400, and the two sets of unlocking structures 500 are all arranged at intervals. During operation, the ultrasonic handle 100 and the puncture handle 200 can be released by rotating the unlocking rod 510 of the two sets of unlocking structures 500, thereby improving the locking performance.

[0109] 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 connected to the same group of unlocking structures 500 in a transmission connection, that is, one driving member 520 can simultaneously cooperate with the two groups of first locking structures 300 in a transmission connection, which is not limited here.

[0110] It is understood that, referring to Figures 1 to 3, in this embodiment of the invention, the ultrasound 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 engaging structure 131, and the puncture catheter assembly 260 is provided with a second engaging structure 2631, the first engaging structure 131 and the second engaging structure 2631 being separable and engaging; wherein, when the first engaging structure 131 and the second engaging structure 2631 are engaged, they can work together with the first locking structure 300 and the second locking structure 400 to make the ultrasound handle 100 and the puncture handle 200 fit and lock together.

[0111] It can be understood that the distal end of the probe shaft 130 away from the operating end of the ultrasound 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.

[0112] With the above structure, when the ultrasonic handle 100 and the puncture handle 200 are fastened, the first fitting structure 131 and the second fitting structure 2631, as well as the first locking structure 300 and the second locking structure 400 cooperate to make the fastening tighter and the mechanism safe and stable.

[0113] Specifically, referring to Figures 2 and 3, in this embodiment, the first mating structure 131 is a mating groove, and the second mating structure 2631 is a mating protrusion. The design of the mating groove and the mating protrusion allows the ultrasonic handpiece 100 and the puncture handpiece 200 to achieve precise alignment during assembly, and the structure is simple and easy to manufacture.

[0114] Of course, in some embodiments, the first mating structure 131 may also be a mating protrusion, the second mating structure 2631 may be a mating groove, or the first mating structure 131 and the second mating structure 2631 may be a pin and a hole mating method, which is not limited here.

[0115] Specifically, in this embodiment, both the first fitting structure 131 and the second fitting structure 2631 are V-shaped fitting structures.

[0116] It is understood that, in the embodiments of the present invention, the general locking and releasing process of the above-mentioned ablation handle device is as follows:

[0117] When the ultrasound handle 100 and the puncture handle 200 are combined, the first engagement structure 131 and the second engagement structure 2631 engage, and the first locking structure 300 and the second locking structure 400 are fastened together. Under the action of the first elastic element 320, they are always in a fastened state. In this embodiment, it can be understood that the first locking structure 300 is a movable buckle, while 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 element 320.

[0118] When the unlocking rod 510 of the unlocking structure 500 rotates downward, the rotating shaft 120 rotates counterclockwise, thereby causing the driving member 520 to squeeze the pushing part 311, causing the pushing part 311 to slide away from the receiving recess 110, driving the connecting pin 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.

[0119] Referring to Figure 8, in this embodiment of the invention, the ultrasonic handle 100 further includes an upper probe housing 140 and a lower probe housing 150 connected to the upper probe housing 140. The connection between the upper probe housing 140 and the lower probe housing 150 can be, for example, using screws and nuts, or snap-fit ​​connections. In this embodiment, the lower probe housing 150 is provided with a receiving recess 110, a first locking structure 300 is provided on the lower probe housing 150, and the unlocking structure 500 and the rotating shaft 120 are both provided on the upper probe housing 140.

[0120] It is understood that, referring to Figures 1, 4, and 10 to 13, in the embodiments of the present invention, the puncture handle 200 further includes a housing, a sliding assembly 270, and an operating mechanism 290. A stop structure 251 is fixedly provided inside the housing. The puncture catheter assembly 260 includes a puncture needle 261, which is slidably disposed inside the housing and extends out of the housing. The sliding assembly 270 is slidably disposed inside the housing and is fixedly connected to the puncture needle 261. 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 disposed in the housing. The operating mechanism 290 slides and drives the sliding assembly 270. The operating mechanism 290 is connected to the locking structure 280 in a transmission manner, and the operating mechanism 290 has a first state and a second state.

[0121] In the first state, the locking structure 280 engages with the stop structure 251 to restrict the sliding component 270 from sliding; in the second state, the operating mechanism 290 drives the locking structure 280 to move until it separates from the stop structure 251 to release the restriction on the sliding component 270 from sliding; after the sliding component 270 slides to the target position, the operating mechanism 290 resets to the first state.

[0122] With the above structure, when the puncture needle 261 is in the initial position and the operating mechanism 290 is in the first state, the locking structure 280 contacts and engages with the stop structure 251 to restrict the sliding component 270 from sliding relative to the housing, thereby restricting the sliding of the puncture needle 261. When sliding is required, the operating mechanism 290 is in the second state, and the operating mechanism 290 drives the locking structure 280 to move until it separates from the stop structure 251, thereby releasing the restriction on the sliding component 270, so that the sliding component can slide relative to the housing to the target position. After sliding to the target position, the operating mechanism 290 returns to the first state, and the locking structure 280 returns to contact and engage with the stop structure 251, thereby locking the sliding component 270 and the puncture needle 261.

[0123] Therefore, it is understandable that through the cooperation of the sliding component 270, the operating mechanism 290, the stop structure 251 and the locking structure 280, locking can be achieved after the puncture needle 261 is pushed to the target position, that is, self-locking, to prevent the puncture needle 261 from sliding after the puncture is in place, which would lead to mistreatment, improve the safety of use, and thus help to avoid changes in the expected ablation treatment area and help to prevent damage to surrounding tissues.

[0124] It should be noted that, in this embodiment of the invention, the puncture needle 261 can slide toward the front end of the housing via the operating mechanism 290 and the sliding component 270 to perform diagnostic and treatment work.

[0125] It is understood that, referring to Figures 1 to 3, in some embodiments of the present invention, the housing includes an upper handle housing 210 and a lower handle housing 220 connected to the upper handle housing 210. The connection between the upper handle housing 210 and the lower handle housing 220 can be, for example, using screws and nuts, snap-fit ​​connections, etc. In this embodiment, a sliding channel is formed between the upper handle housing 210 and the lower handle housing 220 to prevent the operating mechanism 290 from sliding.

[0126] It is understood 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 housing; the locking structure 280 includes a toggle member 281, which is rotatably connected to the sliding assembly 270. The toggle member 281 is provided with a locking part 2811, which is used to engage with the stop structure 251 to restrict the sliding assembly 270 from sliding relative to the housing; wherein, the operating member 291 is throttle-connected to the toggle member 281, and the locking part 2811 can rotate with the toggle member 281 to separate from the stop structure 251.

[0127] With the above structure, when the operating mechanism 290 is in the first state, i.e., the natural static state, the locking part 2811 of the actuating member 281 engages with the stop structure 251 to achieve locking, and the sliding component 270 (including the puncture needle 261) is fixed in a specific position of the housing to prevent the puncture needle 261 from moving accidentally. When sliding is required, the driving operating member 291 moves to switch the operating mechanism 290 to the second state, causing the actuating member 281 to deflect, and the locking part 2811 disengages from the stop structure 251. At this time, the sliding component 270 can be slid towards the front end of the housing 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, accurately controlling the sliding position of the sliding component 270 and the puncture needle 261. With the simple operation of the operating member 291, the user can easily achieve locking and unlocking, which is intuitive and convenient, and makes the device structure compact.

[0128] Of course, in some embodiments, the toggle member 281 may also be slidably connected to the sliding component 270, and the locking structure 280 and the stop structure 251 may be inserted or separated by the sliding of the toggle member 281, which is not limited here; or the toggle member 281 may also be a telescopic structure, which is not limited here.

[0129] It is understood that in this embodiment, the locking part 2811 and the stop structure 251 are in a plug-in engagement; of course, in some embodiments, the locking part 2811 and the stop structure 251 may also be in an abutting engagement, which is not limited here.

[0130] Specifically, referring to Figures 10 to 13, in some embodiments of the present invention, the operating element 291 is configured to be slidable. The operating element 291 includes a sliding button 2911 and a button cover 2912. The operating element 291 is the sliding button 2911. It can be understood that the operating mechanism 290 also includes a mounting base 292. The mounting base 292 is fixedly connected to the sliding assembly 270. The mounting base 292 is provided with a button channel. The sliding button 2911 is slidably inserted into the button channel. The button cover 2912 is provided on the end of the sliding button 2911 facing the toggle member 281. The button cover 2912 is drively connected to the toggle member 281. Referring to the diagram of the second state of the operating mechanism 290, i.e., after being pressed, pressing the sliding button 2911 causes the sliding button 2912 to slide and drive the toggle member 281 to rotate, thereby disengaging the locking structure 280 from the stop structure 251. This allows the user to operate more conveniently, making the entire operating mechanism 290 compact and the transmission method simple and effective, directly converting the user's operation into mechanical action. When the sliding button 2911 is pressed, it pushes the button cover 2912 to slide, thereby driving the toggle member 281 to rotate, thus disengaging the locking structure 280 from the stop structure 251 and providing a safe locking and unlocking mechanism.

[0131] Specifically, in this embodiment, a limiting recess is provided in the button channel to limit the sliding stroke of the sliding button 2911 and improve the stability of the transmission.

[0132] Referring to Figures 12 and 13, specifically, in some embodiments of the present invention, the locking structure 280 further includes a second elastic member 282, which is disposed between the sliding component 270 and the actuating member 281. The second elastic member 282 is used to drive the actuating member 281 to move so that the locking part 2811 is engaged with the stop structure 251.

[0133] With the above structure, when the operating mechanism 290 is in the first state, i.e., the stationary state, under the action of the second elastic member 282, the locking part 2811 of the actuating member 281 engages with the stop structure 251 to achieve locking, and the sliding component 270 (including the puncture needle 261) is fixed in a specific position of the housing to prevent the puncture needle 261 from moving accidentally. When sliding is required, the driving member 291 moves to switch the operating mechanism 290 to the second state, causing the actuating member 281 to deflect, the second elastic member 282 to compress, and the locking part 2811 to disengage from the stop structure 251. The second elastic member 282 provides a restoring force to the actuating member 281, so that the operating member 291 is also reset to the first state. This achieves self-locking, and the user does not need to perform an additional reset action after completing one operation, simplifying the operation process.

[0134] Specifically, referring to FIG12, in this embodiment of the invention, the locking part 2811 is located on one side of the actuating member 281, and the second elastic member 282 is located on the opposite side of the actuating member 281, wherein the locking part 2811 and the second elastic member 282 are aligned.

[0135] With the above structure, since the locking part 2811 and the second elastic member 282 are located on opposite sides of the actuating member 281, the forces they apply to the actuating member 281 can be balanced on the central axis, which helps to maintain the stability of the actuating member 281 and the smoothness of operation. The aligned arrangement provides structural symmetry, and the force transmission path is more direct and simple. The second elastic member 282 can directly apply force to the locking part 2811 during the reset process, ensuring that the locking part 2811 can accurately return to the locked position, thus improving the reliability of operation.

[0136] Of course, in some embodiments, the second elastic member 282 may also be arranged in a staggered manner with the locking part 2811, so that the locking part 2811 can return to the position where it is inserted and engaged with the stop structure 251. This is not limited here.

[0137] It should be noted that in this embodiment, the second elastic element 282 is a spring, the rotatable connection between the actuating element 281 and the sliding assembly 270 is the fulcrum, the actuating element 281 has a power arm and a resistance arm, the power arm is connected to the operating element 291 in a transmission manner, one side of the resistance arm is connected to the locking part 2811, 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.

[0138] Of course, in some embodiments, the second elastic member 282 may also be disposed between the operating member 291 and the sliding component 270. When the second elastic member 282 drives the operating member 291 to reset to the first state, the operating member 291 can drive the toggle member 281 to reset, so that the locking part 2811 returns to the position of being inserted into the stop structure 251. It can be understood that the second elastic member 282 may be not only a cylindrical spring, but also a tension spring or an elastic sheet, which is not limited here.

[0139] Specifically, referring to Figure 12, in this embodiment, the length of the resistance arm of the aforementioned actuating member 281 is greater than the length of the power arm. Logically, this makes the actuating member 281 a lever that requires more effort. Due to the characteristics of a lever that requires more effort, the long resistance arm means that even a slight, unintentional touch will not cause the actuating member 281 to produce a large displacement, 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 actuating member 281 can be controlled, making the operation smoother and avoiding the impact or over-adjustment that may be caused by rapid rotation.

[0140] Specifically, referring to Figures 12 and 13, in this embodiment, the button cover 2912 is provided with a mounting position, and the toggle member 281 is provided with a connecting post 2812. It can be understood that the connecting post 2812 is located on one side of the power arm of the toggle member 281, and the connecting post 2812 is arranged on the same side as the second elastic member 282. The connecting post 2812 is inserted into the mounting position to realize the transmission of the toggle member 281.

[0141] Of course, in other embodiments of the present invention, the above-mentioned operating member 291 can also be configured to be rotatable relative to the housing. By driving the operating member 291 to rotate, the actuating member 281 can also be driven to rotate. For example, the operating member 291 is provided with a plurality of driving protrusions at intervals. When the operating member 291 is rotated, the driving protrusions rotate to be in contact with the actuating member 281, driving the actuating member 281 to move. When the operating member 291 is rotated further, the driving protrusions and the actuating member 281 are misaligned, and the second elastic member 282 drives the actuating member 281 to reset. Alternatively, in other embodiments of the present invention, the operating member 291 is an elastic plate. By pressing the elastic plate to deform it, the elastic plate can be deformed to the point that it can push the actuating member 281 to rotate. This is not limited here.

[0142] It is understood that, referring to Figures 10 to 13, in some embodiments of the present invention, the stop structure 251 includes a plurality of stop portions 2511, and the locking structure 280 contacts and engages with any one of the plurality of stop portions 2511 to restrict the sliding assembly 270 from sliding relative to the housing.

[0143] With the above structure, it can be understood that the locking part 2811 on the actuating member 281 can be inserted and engaged with one of the stop parts 2511, thereby locking the position of the sliding assembly 270. Since there are multiple stop parts 2511, the locking structure 280 can contact different stop parts 2511, thereby realizing multiple different positions of the sliding assembly 270.

[0144] Specifically, referring to Figures 10 to 13, in this embodiment, multiple stop portions 2511 are arranged at intervals, allowing the user to make precise adjustments based on the interval size. Each stop portion 2511 represents a precise position. Of course, in some embodiments, the multiple stop portions 2511 can be arranged continuously connected, which is not limited here.

[0145] It is understood that, referring to Figures 10 to 13, in some embodiments of the present invention, the operating mechanism 290, the stop structure 251, and the locking structure 280 are all provided in two sets; the two sets of operating mechanisms 290 are respectively provided on opposite sides of the housing, and both sets of operating mechanisms 290 are configured to be linked with the sliding component 270.

[0146] The above structure allows the puncture handle 200 of the present invention to slide only when the operating parts 291 of the operating mechanism 290 are pressed simultaneously on both sides of the shell. This prevents accidental activation during surgery, which could cause puncture of other non-treatment tissues or accidental ablation. The handle can be self-locking at any position to avoid changes in the puncture position that could prevent the treatment effect from being achieved, thus greatly improving safety.

[0147] Of course, in some other embodiments, it is not excluded that the operating mechanism 290 is set as a group, and this is not limited here.

[0148] It is understood that, referring to Figures 10 to 13, in some embodiments of the present invention, the sliding assembly 270 includes a slider 271 and a support column 272. The slider 271 is slidably connected to the housing and fixedly connected to the puncture needle 261. The slider 271 is provided with a clearance channel 2711 and a mounting slot 2712. The clearance channel 2711 communicates with the mounting slot 2712. The clearance channel 2711 is used to avoid the stop structure 251, and the mounting slot 2712 is used to install the locking structure 280. The support column 272 is located on one side of the slider 271 and is fixedly connected to the slider 271. The support column 272 is used to install the operating mechanism 290.

[0149] It should be noted that in this embodiment, the puncture needle 261 and the slider 271 are fixedly connected by adhesive coupling.

[0150] The actuating member 281 is rotatably mounted in the mounting slot 2712 via the mounting pin 283, and one end of the second elastic member 282 abuts against the actuating member 281, while the other end abuts against the side wall of the mounting slot 2712. It can be understood that in this embodiment, there are two sets of operating mechanisms 290, so there are also two mounting slots 2712. The mounting slots 2712 and the locking structure 280 are installed in a one-to-one correspondence.

[0151] With the above structure, the clearance channel 2711 is used to avoid the stop structure 251, which means that the stop structure 251 will not interfere with the slider 271 during its movement, ensuring smooth operation. The mounting slot 2712 is used to install the locking structure 280. The above design allows the locking structure 280 to be fixed on the slider 271, while also maintaining stability when the slider 271 moves. The support column 272 is fixedly connected to one side of the slider 271, providing stable support for the operating mechanism 290 and ensuring the stability of the operating mechanism 290 during operation.

[0153] With the above structure, the guide rod 250 is fixed inside the housing, providing precise guidance for the slider 271 and ensuring that the slider 271 maintains linear motion during sliding, thus improving the accuracy and stability of the operation. The guide rod 250 and the clearance channel 2711 are slidably engaged, allowing the slider 271 to slide freely on the guide rod 250. At the same time, the design of the clearance channel 2711 ensures that the stop structure 251 does not obstruct the movement of the slider 271. The stop structure 251 is provided along the length of the guide rod 250, which makes the overall structure more compact, optimizes space utilization, and can also restrict the movement of the slider 271 at specific positions, thereby achieving the function of positioning or limiting the operating range, making the movement of the slider 271 more precise. Users can accurately control the sliding component 270 and the puncture needle 261 to reach the target position.

[0154] It is understood that, referring to Figures 10 to 13, in this embodiment, the guide rod 250 has stop structures 251 on its opposite side walls.

Each row of steam output groups includes multiple steam outlet holes 2613, and the multiple steam outlet holes 2613 are equally spaced at the front end of the puncture needle 261 along the length direction of the puncture needle 261.

[0166] The above structure enables steam ablation, which is suitable for a wider range of patients in the treatment of uterine fibroids compared to traditional radiofrequency ablation. The design of the annular steam outlet 2613 improves the quality of the steam output, which is conducive to achieving the expected ablation effect.

[0167] It should be noted that, referring to Figures 3 and 10, in this embodiment, the steam output group has three rows, and each row of the steam output group has four steam outlet holes 2613. Of course, this is not limited here, and the corresponding number can be set as needed.

[0168] In this embodiment, the diameter of the steam outlet 2613 is 0.3 mm, which further improves the quality of the steam.
