In the unlocked state, the stepless adjustment structure 200 is used to steplessly adjust the angle of the ultrasonic transducer 100.
[0038] By adopting the stepless adjustment structure 200 to connect the ultrasonic transducer 100, the problem of the angle adjustment limitation of the ultrasonic transducer 100 in the prior art is effectively solved. In the unlocked state, the stepless adjustment structure 200 can realize the continuous and free adjustment of the angle of the ultrasonic transducer 100, breaking through the original limitation of only being able to switch between fixed angles, greatly improving the flexibility and accuracy of angle adjustment, thereby meeting the diverse use needs, especially in precision medical operations such as uterine fibroid ablation, meeting the high requirements for ultrasound-guided angle changes.
[0039] In addition, the deflection mechanism of the uterine fibroid ultrasonic transducer also has a design feature to prevent accidental touch. The stepless adjustment structure 200 has two modes: locked state and unlocked state. In the locked state, the angle change caused by accidental touch can be effectively avoided, thereby ensuring the stable operation of the ultrasonic transducer 100 at the set angle and maintaining the accuracy and consistency of ultrasonic imaging, which is crucial to improving the safety and success rate of uterine fibroid ablation surgery.
[0040] According to one embodiment of the present utility model, Figure 2 , Figure 6 and Figure 8 As shown, the stepless adjustment structure 200 includes a supporting shell 210, an angle adjustment component 220 and a locking component 230; the supporting shell 210 can be columnar; the angle adjustment component 220 is arranged on the supporting shell 210 and is connected to the ultrasonic transducer 100, and in the unlocked state, it is used to steplessly adjust the angle of the ultrasonic transducer 100; the locking component 230 is arranged on the angle adjustment component 220, and in the locked state, the locking component 230 can be connected to the supporting shell 210; in the unlocked state, the locking component 230 is separated from the supporting shell 210.
[0041] In specific implementation, in the unlocked state, the angle adjustment component 220 can drive the ultrasonic transducer 100 to rotate steplessly; in the locked state, the locking component 230 is connected to the supporting shell 210 to prevent the ultrasonic transducer 100 from accidentally rotating; the stepless adjustment structure 200 in the deflection mechanism of the uterine fibroid ultrasonic transducer is composed of three parts: the supporting shell 210, the angle adjustment component 220 and the locking component 230. The structural design is compact and reasonable, which can not only ensure the precise stepless adjustment of the angle of the ultrasonic transducer 100, but also keep its angle unchanged in the locked state through the locking component 230, thereby increasing the safety of the equipment.
[0042] According to one embodiment of the present utility model, Figures 6 to 8 , Fig. 9 and Fig.10 As shown, the angle adjustment component 220 has a setting groove 2200; the locking component 230 is located in the setting groove 2200 and can be slidably connected to the groove wall of the setting groove 2200, the locking component 230 has a locking position and an unlocking position, and the locking component 230 can switch between the locking position and the unlocking position by being slidably connected; in the locked state, the locking component 230 is located in the locked position and is connected to the supporting shell 210; in the unlocked state, the locking component 230 is located in the unlocked position and is separated from the supporting shell 210.
[0043] In specific implementation, when the locking assembly 230 is in the locked position, it is connected to the supporting housing 210 to fix the angle of the ultrasonic transducer 100; when it is in the unlocked position, it is separated from the supporting housing 210, allowing stepless adjustment of the angle of the ultrasonic transducer 100. By providing a slot 2200 in the angle adjustment assembly 220 and arranging a slidable locking assembly 230 in the slot, the locking assembly 230 is switched between the locked position and the unlocked position, providing a simple and convenient angle locking and unlocking mechanism.
[0044] According to one embodiment of the present utility model, Figures 6 to 8 , Fig. 9 and Fig.10 As shown, the locking component 230 includes a pressing component 231, an elastic component 232 (such as a spring) and a locking component 233; the pressing component 231 is located in the setting groove 2200 and can be slidably connected to the groove wall of the setting groove 2200; the elastic component 232 is located in the setting groove 2200 and is clamped between the angle adjustment component 220 and the pressing component 231. In the locked state, the elastic component 232 is in a released state; in the unlocked state, the elastic component 232 is in a compressed state; the locking component 233 can be strip-shaped, the locking component 233 can be columnar, and can be slidably connected to the end of the rotating shaft; the locking component 233 is arranged on the pressing component 231, in the locked state, the locking component 233 is connected to the supporting shell 210; in the unlocked state, the locking component 233 is separated from the supporting shell 210.
[0045] In specific implementation, in the locked state, the elastic component 232 is released, and the locking component 233 is connected to the supporting shell 210, that is, it is in the locked state under normal conditions; when unlocking, the pressing component 231 is pressed, the elastic component 232 is compressed, and the locking component 233 is driven to separate from the supporting shell 210, thereby releasing the lock. The locking assembly 230 includes the pressing component 231, the elastic component 232 and the locking component 233. This design helps to achieve fast and reliable angle switching, and at the same time, the compression and release characteristics of the elastic component 232 are used to ensure the stability of the locking action and prevent misoperation.
[0046] According to one embodiment of the present utility model, Fig.10 As shown, the support shell 210 is provided with a braking portion 211 ; in a locked state, the locking component 233 abuts against the braking portion 211 ; in an unlocked state, the locking component 233 is separated from the braking portion 211 .
[0047] In specific implementation, the locking component 233 directly abuts the brake part 211 in the locked state to form a stable locking fit; in the unlocked state, it is separated from the brake part 211 to allow the angle of the ultrasonic transducer 100 to be adjusted. By adding the brake part 211 to the support shell 210, the working effect of the locking assembly 230 is further enhanced to ensure that the angle of the ultrasonic transducer 100 will not be changed due to external interference in the locked state.
[0048] According to one embodiment of the utility model, the supporting shell 210 has a accommodating cavity 212 and a port 213 that can communicate with the accommodating cavity 212; the ultrasonic transducer 100 is located at the port 213 and can be rotatably connected to the edge of the port 213 of the supporting shell 210; the angle adjustment component 220 can be rotatably connected to the ultrasonic transducer 100.
[0049] According to one embodiment of the present utility model, the connection point between the ultrasonic transducer 100 and the supporting shell 210 is the first connection point; the connection point between the angle adjustment component 220 and the ultrasonic transducer 100 is the second connection point; there is a distance between the first connection point and the second connection point.
[0050] According to one embodiment of the utility model, the angle adjustment component 220 includes a rotation drive component 221, a linear motion component 222 and a transmission component 223; the rotation drive component 221 is arranged on the support shell 210, and in the unlocked state, the rotation drive component 221 is used to drive the linear motion component 222 to perform linear motion; the linear motion component 222 is located in the accommodating cavity 212 and can be slidably connected to the cavity wall of the accommodating cavity 212; the transmission component 223 is located between the ultrasonic transducer 100 and the support shell 210, and the transmission component 223 has a first end 2231 and a second end 2232; the first end 2231 can be rotatably connected to the end of the linear motion component 222; the second end 2232 can be rotatably connected to the ultrasonic transducer 100; the locking component 230 is arranged on the rotation drive component 221.
[0051] In a specific implementation, when the uterine fibroid ultrasound transducer deflection mechanism is in an unlocked state, the user can activate the angle adjustment function by operating the rotation drive component 221. Figure 7 As shown, the rotating driving component 221 can make the linear motion component 222 slide along the cavity wall in the accommodating cavity 212, and the displacement of its linear motion is effectively transmitted to the transmission component 223. The first end 2231 of the transmission component 223 is connected to the end of the linear motion component 222. As the linear motion component 222 moves, the transmission component 223 will undergo corresponding rotation changes. The second end 2232 of the transmission component 223 is connected to the ultrasonic transducer 100. When the transmission component 223 rotates, the rotation is transmitted to the ultrasonic transducer 100, so that the ultrasonic transducer 100 can perform continuous and stepless angular rotation around a certain axis.
[0052] Through the structural setting, the following technical effects are achieved: 1. Precise angle adjustment: Due to the combination of rotation drive-linear motion-transmission component 223, the utility model can achieve extremely precise angle adjustment of the ultrasonic transducer 100, and can easily cope with both fine-tuning and large-scale changes in angle, meeting the needs of various application scenarios. 2. Stepless adjustment: Due to the existence of the stepless adjustment structure 200, the angle of the ultrasonic transducer 100 can be continuously adjusted within any desired angle range, without being limited to a few preset fixed angles, which greatly improves the flexibility and applicability of the device. 3. Stability and reliability: The locking component 230 is set on the rotation drive component 221, which can ensure that when no adjustment is required, the angle of the ultrasonic transducer 100 can be stably maintained, avoiding angle changes caused by external factors during use, thereby improving the stability of the device operation and the reliability of the treatment process.
[0053] According to one embodiment of the utility model, the supporting shell 210 has a shaft setting through hole 214 connected to the accommodating chamber 212; the linear motion component 222 includes a rack; the rotation driving component 221 includes a gear shaft 2211 and a toggle rotating member 2212; the gear shaft 2211 includes a gear and a rotating shaft; the gear is located in the accommodating chamber 212 and meshes with the rack; the rotating shaft is coaxially arranged at the end of the gear and can be rotatably passed through the shaft setting through hole 214; the toggle rotating member 2212 can be a "U"-shaped structure with the opening facing downward, the toggle rotating member 2212 is arranged outside the accommodating chamber 212, and is connected to the rotating shaft to drive the gear to rotate; the locking assembly 230 is arranged on the toggle rotating member 2212.
[0054] In specific implementation, when the operator triggers the unlocking state, the operator can apply force to the outside by turning the rotating member 2212; the rotating member 2212 is connected to the rotating shaft, and the rotating shaft drives the gear shaft 2211 to rotate through the transmission force; the gear on the gear shaft 2211 is located in the accommodating cavity 212 and forms a meshing relationship with the rack, such as Figure 8 As shown, when the gear rotates, due to the meshing action of the gear and the rack, the rack will perform a linear motion along a specific direction in the accommodating cavity 212; the rack in the linear motion component 222 serves as a key link in the transmission, and its linear motion will be transmitted to the ultrasonic transducer 100 through the transmission component 223; one end of the transmission component 223 is rotationally connected to the end of the rack, and the other end is rotationally connected to the ultrasonic transducer 100, so the linear motion of the rack is converted into an angle change of the ultrasonic transducer 100; the locking assembly 230 is arranged on the toggle rotating member 2212 to ensure that the toggle rotating member 2212 cannot be easily touched in the unlocked state, thereby preventing the accidental adjustment of the angle of the ultrasonic transducer 100.
[0055] The above-mentioned structural setting has the following technical effects: 1. Precise transmission: Through the meshing transmission of the gear and the rack, the precise conversion from rotational drive to linear motion and then to angle change is realized, ensuring the accuracy of the angle adjustment of the ultrasonic transducer 100. 2. Compact structure: The method of penetrating the through hole through the rotating shaft not only simplifies the internal structure, but also ensures the compactness and lightweight design of the overall equipment. 3. Easy operation: The angle of the ultrasonic transducer 100 can be controlled by externally turning the rotating member 2212, making the operation more intuitive and simple.
[0056] According to one embodiment of the utility model, a setting groove 2200 is provided on the toggle rotating member 2212; the locking assembly 230 is located in the setting groove 2200 and can be slidably connected to the groove wall of the setting groove 2200, the locking assembly 230 has a locking position and an unlocking position, and the locking assembly 230 can switch between the locking position and the unlocking position; in the locked state, the locking assembly 230 can be connected to the supporting shell 210; in the unlocked state, the locking assembly 230 is separated from the supporting shell 210. The locking assembly 230 includes a pressing component 231, an elastic component 232 and a locking component 233; the pressing component 231 is located in the setting groove 2200 and can be slidably connected to the groove wall of the setting groove 2200; the elastic component 232 is located in the setting groove 2200 and is sandwiched between the toggle rotating member 2212 and the pressing component 231. In the locked state, the elastic component 232 is in a released state; in the unlocked state, the elastic component 232 is in a compressed state; the locking component 233 is arranged on the pressing component 231. In the locked state, the locking component 233 is connected to the supporting shell 210; in the unlocked state, the locking component 233 is separated from the supporting shell 210. The edge of the shaft setting through hole 214 is provided with a brake part 211; in the locked state, the locking component 233 can pass through the side wall of the shaft to abut the brake part 211; in the unlocked state, the locking component 233 is separated from the brake part 211. The toggle rotating member 2212 has an arc-shaped groove 2210 surrounding the rotating shaft; the braking part 211 is an arc-shaped brake pad, which is arranged concentrically with the arc-shaped groove 2210, and the braking part 211 can be slidably connected to the groove wall of the arc-shaped groove 2210; the side wall of the rotating shaft has a through hole; in the locked state, the locking part 233 can pass through the through hole to abut the arc-shaped brake pad.
[0057] In a specific implementation, the pressing component 231 will be arranged in the groove 2200 along the Figure 8 The locking member 233 moves together with the dotted arrow in the figure. In the locked state, the elastic member 232 is released, and the locking member 233 moves under the action of the restoring force of the elastic member 232. Fig.10As shown, the brake part 211 on the supporting shell 210 is automatically abutted, thereby preventing the rotation of the rotating shaft and achieving the locking of the angle of the ultrasonic transducer 100. When the angle of the ultrasonic transducer 100 needs to be adjusted, the operator acts on the toggle rotating member 2212 again, and the pressing member 231 slides in the opposite direction under pressure, and the elastic member 232 is compressed at this time. As the pressing member 231 slides, the locking member 233 separates from the brake part 211, no longer preventing the rotation of the rotating shaft, and enters the unlocked state, at which time the angle of the ultrasonic transducer 100 can be adjusted steplessly. In order to enhance the stability of the locking, the brake part 211 is designed to be an arc-shaped brake pad, which is concentrically arranged and slidably connected with the arc-shaped groove 2210 on the toggle rotating member 2212. When the locking member 233 is in the locked state, it can abut the arc-shaped brake pad through the perforation of the side wall of the rotating shaft to form a lock, ensuring that the rotating shaft will not rotate accidentally in the locked state, thereby ensuring the stability of the angle of the ultrasonic transducer 100. The locking assembly 230 is ingeniously designed, and can achieve rapid locking and unlocking of the ultrasonic transducer 100 degrees through simple sliding and the use of elastic elements. The operation is simple, safe and reliable.
[0058] In this embodiment, the toggle rotating member 2212 can be set as a hollow structure, including a first shell and a second shell that are interlocked; the first shell is located above the second shell; the setting groove 2200 is set on the second shell; the braking part 211 can be located inside the toggle rotating member 2212, which is more beautiful.
[0059] It is understandable that when the rotating member 2212 is rotated, the position of the braking portion 211 does not change due to the arrangement of the arc-shaped groove 2210 .
[0060] The utility model also provides a uterine fibroid steam ablation device, comprising: a uterine fibroid ultrasonic transducer deflection mechanism as described above. The specific structure, working principle and beneficial effects of the uterine fibroid steam ablation device are the same as those of the above embodiment, and will not be repeated here.
