Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this embodiment, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] In this embodiment, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0036] Figures 1 to 7The uterine fibroid ultrasonic transducer rotary actuator and steam ablation device provided by the utility model are demonstrated. As can be seen from the figure, the uterine fibroid ultrasonic transducer rotary actuator of the utility model includes an ultrasonic transducer 100 and a stepless adjustment mechanism 200; the stepless adjustment mechanism 200 is connected to the ultrasonic transducer 100 and is used to steplessly adjust the angle of the ultrasonic transducer 100.

[0037] The utility model provides an improved uterine fibroid ultrasonic transducer rotation actuator, the unit is specially equipped with a stepless adjustment mechanism 200, this innovative design enables the angle of the ultrasonic transducer 100 to be adjusted continuously and flexibly, rather than being limited to a few preset fixed positions.

[0038] By integrating the stepless adjustment mechanism 200 with the ultrasonic transducer 100, a significant improvement in the accuracy of ultrasonic guidance is achieved, especially in medical equipment such as uterine fibroid steam ablation device. The incident angle of the ultrasonic wave can be accurately adjusted according to the actual location and shape of the lesion, thereby more accurately guiding the ablation process and improving treatment efficiency and safety.

[0039] This technology improves the operational convenience and adaptability of medical equipment. Doctors can finely adjust the angle of the ultrasonic transducer 100 in real time during surgery to ensure the clarity of the ultrasonic image and the effective coverage of the ablation treatment, and reduce the risk of blind spots or incomplete ablation due to angle limitations.

[0040] In summary, this technology effectively solves the problem of angle adjustment limitations in the prior art and enhances the precise positioning and all-round guiding capabilities of the ultrasonic transducer 100 in uterine fibroid ablation and other similar applications.

[0041] It is understandable that the angle limitation of the ultrasonic transducer 100 is not conducive to clearly scanning the location of lesions such as fibroids, which will increase the time for finding fibroids and further increase the time of the entire operation.

[0042] In this embodiment, the ultrasonic transducer 100 may be called an ultrasonic probe, and the ultrasonic transducer 100 can be adjusted steplessly within a range of 0 to 60 degrees.

[0043] According to one embodiment of the utility model, the stepless adjustment mechanism 200 includes a connecting structure 210 and a driving structure 220; the connecting structure 210 can be rotatably connected to the ultrasonic transducer 100; the driving structure 220 is arranged on the connecting structure 210 and can be connected to the ultrasonic transducer 100, and is used to drive the ultrasonic transducer 100 to move relative to the connecting structure 210 to steplessly adjust the angle of the ultrasonic transducer 100.

[0044] In specific implementation, the connecting structure 210 can be rotatably connected to the ultrasonic transducer 100, and the driving structure 220 is arranged on the connecting structure 210. By driving the ultrasonic transducer 100 to move relative to the connecting structure 210, stepless adjustment at the desired angle can be achieved. This design increases the stability and adjustment accuracy of the system.

[0045] In this embodiment, the connection structure 210 is rotatably connected to the ultrasonic transducer 100 via the first pin 300 .

[0046] According to one embodiment of the utility model, the driving structure 220 includes a linear motion component 221 and a transmission component 222; the linear motion component 221 is arranged on the connecting structure 210; the transmission component 222 has a first end 2221 and a second end 2222; the first end 2221 is rotatably connected to the linear motion component 221; the second end 2222 is rotatably connected to the ultrasonic transducer 100; wherein, the connection point between the connecting structure 210 and the ultrasonic transducer 100 is a first connection point (for example, the position of the first pin 300); the connection point between the transmission component 222 and the ultrasonic transducer 100 is a second connection point (for example, the position of the third pin 500); there is a distance between the first connection point and the second connection point.

[0047] In specific implementation, through the cooperation of the linear motion component 221 and the transmission component 222, the ultrasonic transducer 100 can maintain a certain distance between the two connection points while performing stepless angle changes. This not only ensures the smooth rotation of the ultrasonic transducer 100, but also optimizes the overall structural layout, which is conducive to the miniaturization and precision design of the device.

[0048] In this embodiment, the connection structure 210 has an inner cavity 2110, and the inner cavity 2110 passes through the end of the connection structure 210; the ultrasonic transducer 100 is located at the end of the connection structure 210; the linear motion component 221 is located in the inner cavity 2110 and is slidably connected to the cavity wall of the inner cavity 2110; the transmission component 222 is located between the ultrasonic transducer 100 and the linear motion component 221. The first end 2221 is rotatably connected to the linear motion component 221 through the second pin 400; the second end 2222 is rotatably connected to the ultrasonic transducer 100 through the third pin 500.

[0049] According to one embodiment of the utility model, the linear motion assembly 221 includes a rotation driving component 2210 and a linear motion component 2220; the rotation driving component 2210 is arranged on the cavity wall of the inner cavity 2110; the linear motion component 2220 is connected to the rotation driving component 2210 and can be slidably connected to the cavity wall of the inner cavity 2110; the first end 2221 can be rotatably connected to the end of the linear motion component 2220.

[0050] During specific implementation, the rotating driving component 2210 is installed in the inner cavity 2110, and the rotating driving component 2210 can rotate. The rotation of the rotating driving component 2210 can drive the linear motion component 2220 to move linearly. The linear motion of the linear motion component 2220 can drive the ultrasonic transducer 100 to move relative to the connecting structure 210 through the transmission assembly 222 to achieve stepless adjustment at any desired angle.

[0051] According to one embodiment of the present invention, the rotation driving component 2210 includes a limiter 2211, a bearing 2212, a screw 2213, a rotation driving component 2214 and a first screw hole component 2215 (such as a nut); the limiter 2211 is arranged on the cavity wall of the inner cavity 2110 and is used for the linear motion limiter groove 2201; the linear motion limiter groove 2201 is extended along the axial direction O of the screw; the bearing 2212 is arranged on the cavity wall of the inner cavity 2110; the screw 2213 is located in the linear motion limiter groove 220 1, and can be rotatably inserted into the bearing 2212; the rotation driving member 2214 is arranged on the screw rod 2213, and is used to drive the screw rod 2213 to rotate; the first screw hole member 2215 is located in the linear motion limiting groove 2201, and can be slidably connected to the groove wall of the linear motion limiting groove 2201, and can be movably sleeved on the screw rod 2213, and the first screw hole member 2215 can perform linear motion along the axial direction O of the screw rod under the drive of the rotation driving member 2214; the linear motion component 2220 is connected to the first screw hole member 2215.

[0052] In specific implementation, the rotating driving member 2214 (such as a motor or the toggle driving wheel described below) drives the screw 2213 to rotate, and the first screw hole member 2215 performs linear motion along the axial direction O of the screw 2213. Since the first screw hole member 2215 is connected to the linear motion component 2220, the rotation of the screw 2213 is finally converted into the linear motion of the linear motion component 2220. This linear motion is then transmitted to the ultrasonic transducer 100 through the transmission assembly 222, thereby realizing stepless adjustment of the angle of the ultrasonic transducer 100.

[0053] It can be understood that, through the above-mentioned structural setting, reverse self-locking can also be achieved, that is, the rotation of the rotating drive member 2214 can change the angle of the ultrasonic transducer 100, but conversely, if an external force is directly applied to the surface of the ultrasonic transducer 100, not only the angle of the ultrasonic transducer 100 will not change, but the rotating drive member 2214 will not rotate either.

[0054] It can also be understood that in a threaded transmission system, if the static friction coefficient between the screw and the nut is large enough, when the nut is subjected to an axial load and the screw stops rotating, the nut will not slide in the opposite direction due to gravity or other external forces. This is the friction self-locking phenomenon. In the stepless adjustment mechanism 200 of the rotary actuator of the uterine fibroid ultrasonic transducer, if the design is reasonable, this principle can be used to achieve self-locking of the nut and the screw after adjusting to a specific angle, so that the ultrasonic transducer 100 remains at the set angle and does not change, thereby enhancing stability.

[0055] According to one embodiment of the utility model, the rotating driving component 2210 also includes a second screw hole component 2216 (for example, a nut) and an elastic component 2217 (for example, a spring); the second screw hole component 2216 is located in the linear motion limit groove 2201, and can be slidably connected to the groove wall of the linear motion limit groove 2201, and can be movably mounted on the screw rod 2213, and the second screw hole component 2216 can perform linear motion along the axial direction O of the screw rod under the drive of the rotating driving component 2214; the elastic component 2217 is clamped between the first screw hole component 2215 and the second screw hole component 2216.

[0056] In specific implementation, the second screw hole member 2216 is also movably sleeved on the screw rod 2213 and is slidably connected to the groove wall of the linear motion limiting groove 2201. Under the action of the rotating driving member 2214, the first screw hole member 2215 and the second screw hole member 2216 will move synchronously along the axial direction O of the screw rod 2213, and the elastic member 2217 is sandwiched between the two nuts to maintain tension, which can improve the stability and stability during the adjustment process, prevent excessive relaxation, and ensure that the angle change of the ultrasonic transducer 100 during the adjustment process is more linear and accurate.

[0057] According to an embodiment of the present invention, the connection structure 210 has a dial wheel setting hole that can communicate with the inner cavity 2110; the rotating driving member 2214 is a dial driving wheel, which is sleeved on the screw rod 2213 and exposes the dial wheel setting hole.

[0058] In specific implementation, by setting a dial setting hole on the connecting structure 210 and using a dial driving wheel as the rotating driving member 2214, the control experience is optimized, so that medical staff can rotate the dial driving wheel through intuitive and simple manual operation to accurately control the angle change of the ultrasonic transducer 100.

[0059] It is understandable that when the medical staff releases the toggle drive wheel, the angle of the ultrasonic transducer 100 will be locked unless the medical staff toggle the toggle drive wheel again.

[0060] According to one embodiment of the utility model, the limiting member 2211 includes a first limiting plate and a second limiting plate; the first limiting plate and the first limiting plate are extended along the axial direction O of the screw, and the plate surface of the first limiting plate and the plate surface of the first limiting plate are relatively arranged and have a gap; the gap is a linear motion limiting groove 2201.

[0061] During specific implementation, a linear motion limiting groove 2201 is formed through the design of the limiting member 2211 (the first limiting plate and the second limiting plate).

[0062] According to one embodiment of the utility model, the connecting structure 210 may include a shell 211 and a connecting rod 212; the shell 211 has a accommodating space and an insertion port that can be connected to the accommodating space; the connecting rod 212 is inserted into the shell 211 through the insertion port, and the shell 211 has a sliding channel running through both ends thereof; wherein, the accommodating space and the sliding channel are surrounded to form an inner cavity 2110.

[0063] The utility model also provides a uterine fibroid steam ablation device, comprising: a uterine fibroid ultrasonic transducer rotary actuator as in the above embodiment. The specific structure, working principle and beneficial effects of the uterine fibroid steam ablation device are the same as those in the above embodiment, and will not be repeated here.
