Description

Technical Field

[0002] Ultrasonic products refer to various devices and instruments that utilize ultrasonic technology. In the medical field, ultrasonic energy is used to treat diseases, and an ultrasonic linear handpiece is one such ultrasonic therapy device.

[0003] In related technologies, the ultrasonic linear handpiece drives the transducer of the treatment head to perform linear reciprocating motion through a motor motion mechanism. The motor motion mechanism converts the rotation of the motor shaft into the linear reciprocating motion of the slider through a lead screw and slider structure. The transducer is usually directly mounted on the slider. However, due to the limitation of the lead screw position, the transducer can only be mounted on the side of the slider that does not interfere with the lead screw. This can cause the transducer to shake or jam due to inertia when the treatment head starts and stops, affecting the operation of the treatment head. In order to ensure the stable movement of the transducer, additional double cylindrical guide rails or other structures are set to limit and guide the transducer. However, this increases the number of parts in the handpiece and the assembly process requirements are also higher. Problems with the machining accuracy of related parts or the assembly between parts can easily cause the transducer to run unevenly, affecting the normal use of the ultrasonic linear handpiece.

[0033] This utility model proposes a handle 100.

[0034] Please see Figure 1 and Figure 6 In one embodiment of this utility model, the handle 100 includes a drive motor 1, a rotary motion part 2, a linear motion part 3, and a connecting rod 4; the drive end of the drive motor 1 is connected to the rotary motion part 2, and the drive motor 1 is used to drive the rotary motion part 2 to rotate around a first direction; the linear motion part 3 is connected to the rotary motion part 2 in a transmission manner, and the rotary motion part 2 is used to drive the linear motion part 3 to move along the first direction; the connecting rod 4 is disposed on the linear motion part 3, and the connecting rod 4 is used to detachably connect to the transducer 16 of the treatment head, and the connecting rod 4 can drive the transducer 16 to move along the first direction.

[0035] The rotary motion unit 2 and the linear motion unit 3 are connected by a transmission, which can convert the rotational motion of the rotary motion unit 2 into the linear motion of the linear motion unit 3. This, in turn, drives the connecting rod 4 connected to the linear motion unit 3 to perform linear reciprocating motion, and ultimately drives the transducer 16 connected to the connecting rod 4 to perform linear reciprocating motion. It should be noted that the combination of the rotary motion unit 2 and the linear motion unit 3 can be a crank-slider structure, with the crank and the slider connected. A groove is provided to limit the movement trajectory of the slider to a straight line. The drive end of the drive motor 1 drives the crank to rotate together, thereby driving the slider to perform linear reciprocating motion along the groove, which in turn drives the connecting rod 4 to perform linear reciprocating motion, thus causing the transducer 16 to perform linear reciprocating motion.

[0036] In other embodiments, the combination of the rotary motion unit 2 and the linear motion unit 3 can also be a combination of a sector gear and a rack. Two racks are symmetrically arranged on both sides of the sector gear, and the two racks can move together. The sector gear rotates unidirectionally under the drive of the drive end of the drive motor 1. When the teeth of the sector gear mesh with the teeth of one of the racks, the rack moves along the tangential direction of the rotation direction of the toothed gear. When the teeth of the sector gear rotate to the other side, they mesh with the teeth of the other rack, driving the rack to move along the tangential direction of the rotation direction of the sector gear. Since the rotation directions of the sector gear on both sides are opposite, the linear reciprocating motion of the rack can be realized.

[0037] In the technical solution of this utility model, the drive motor 1 drives the rotary motion part 2 to rotate around a first direction through the drive end, thereby driving the linear motion part 3 to perform linear reciprocating motion along the first direction. The transducer 16 can be connected to the linear motion part 3 through the connecting rod 4, so as to follow the linear motion part 3 to perform linear reciprocating motion, thereby realizing planar treatment of the treatment head. In this way, the handle 100 has fewer parts, a simple and compact structure, and low assembly process requirements. In addition, the transducer 16 and the connecting rod 4 are detachably connected, which also facilitates the replacement and maintenance of the transducer 16 and improves flexibility.

[0038] Furthermore, in one embodiment of this utility model, please refer to... Figure 1 and Figure 3 The handle 100 also includes a bracket 5. The drive motor 1 is connected to the bracket 5, the rotary motion part 2 is rotatably connected to the bracket 5, and the linear motion part 3 is slidably connected to the bracket 5. The bracket 5 provides a stable support platform for the drive motor 1, the rotary motion part 2, and the linear motion part 3. The rotary motion part 2 is rotatably mounted on the bracket 5, and the linear motion part 3 is slidably mounted on the bracket 5. This helps maintain the relative positions of the components during movement, facilitates power transmission between the rotary motion part 2 and the linear motion part 3, reduces vibration, and improves the stability of the handle 100. In addition, by designing the shape of the bracket 5, the spatial positions of the drive motor 1, the rotary motion part 2, and the linear motion part 3 can be rationally arranged, making the layout of the handle 100 more compact, thereby reducing the size of the handle 100 and facilitating integration and use.

[0039] Specifically, in one embodiment of this utility model, please refer to Figure 4 and Figure 5The linear motion part 3 has a first threaded hole, and the rotary motion part 2 passes through the threaded hole of the linear motion part 3 and is threadedly connected to the linear motion part 3. Through this threaded connection, the power transmission between the rotary motion part 2 and the linear motion part 3 is more precise and stable. The threaded connection provides excellent torque transmission, ensuring that rotary motion can be efficiently converted into linear motion. The threaded connection has higher structural strength, and this connection method can withstand greater loads, improving the durability and reliability of the entire handle 100.

[0040] To ensure the stability of the linear motion unit 3, in one embodiment of this utility model, please refer to... Figure 3 The handle 100 also includes a slide rail 6 and a slider 7. The slide rail 6 is mounted on the bracket 5, and the slider 7 is slidably mounted on the slide rail 6. The linear motion unit 3 is detachably connected to the slider 7. The slide rail 6 provides stable guidance for the slider 7, allowing the linear motion unit 3 to perform smooth linear motion on the slide rail 6 via the slider 7. Furthermore, the cooperation between the slide rail 6 and the slider 7 reduces friction during linear motion, lowers wear, thereby reducing energy loss, improving motion efficiency, and extending the service life of related components. The detachable connection design allows for quick disassembly and reinstallation when maintenance or replacement of the linear motion unit 3 is required, improving maintenance convenience.

[0041] Specifically, in one embodiment of this utility model, please refer to... Figure 3 The handle 100 also includes a first locking member 8. A second threaded hole is provided on the linear motion part 3. The first locking member 8 passes through the second threaded hole of the linear motion part 3 and connects to the slider 7. The first locking member 8 ensures a stable connection between the linear motion part 3 and the slider 7, preventing accidental loosening of the linear motion part 3 under high load or vibration conditions. Furthermore, the first locking member 8 allows for quick installation and removal between the linear motion part 3 and the slider 7. Preferably, the first locking member 8 is a screw. In other embodiments, the linear motion part 3 can connect to the slider 7 through the cooperation of a slot and a buckle, thereby driving the slider 7 to move on the slide rail 6.

[0042] To ensure a stable connection, please refer to one embodiment of this utility model. Figure 3 and Figure 5 The linear motion unit 3 has a mounting hole, and one end of the connecting rod 4 is inserted into the mounting hole and has an interference fit with it. The interference fit means that the connection between the connecting rod 4 and the mounting hole is very tight, significantly enhancing the strength and stability of the connection. Alternatively, in other embodiments, a threaded hole can be provided at the end of the connecting rod 4 that is inserted into the mounting hole, and a through hole communicating with the mounting hole can be provided on the side of the linear motion unit 3 opposite to the connecting rod 4. A bolt or screw is then threaded through the through hole and connected to the connecting rod 4, thereby fixing the connecting rod 4.

[0043] Furthermore, in one embodiment of this utility model, please refer to... Figure 3 The bracket 5 is equipped with a stop block 12, located at the end of the bracket 5 furthest from the drive motor 1. The end of the rotating motion part 2 furthest from the drive motor 1 is rotatably mounted on the stop block 12, thereby providing a fulcrum for the rotating motion part 2 and improving structural stability. The handle 100 also includes two bearings 13, respectively located on the bracket 5 and the stop block 12, and respectively fitted onto both ends of the rotating motion part 2. The bearings 13 extend the service life of the rotating motion part 2. Furthermore, in other embodiments, a connecting plate 14 can be provided, with both ends of the connecting plate 14 connected to the bracket 5 and the stop block 12 respectively. Thus, the connecting plate 14, the bracket 5, and the stop block 12 enclose a limiting space, within which the linear motion part 3 slides, allowing for better selection of the direction of movement of the linear motion part 3.

[0044] Furthermore, in one embodiment of this utility model, please refer to... Figure 1 and Figure 3 The stop block 12 is also provided with a guide hole, through which the end of the connecting rod 4 away from the linear motion part 3 passes. This provides precise guidance for the connecting rod 4, ensuring that the connecting rod 4 can move stably in the first direction, and also provides a fulcrum for the connecting rod 4 to prevent it from shaking during movement.

[0045] To ensure transmission efficiency, please refer to one embodiment of this utility model. Figure 2 and Figure 4 The handle 100 also includes a coupling 9, one end of which is connected to the output shaft of the drive motor 1, and the other end of which is connected to the rotary motion part 2. The coupling 9 can effectively transmit the output torque of the drive motor 1 to the rotary motion part 2, maintaining high transmission efficiency and reducing energy loss.

[0046] Furthermore, the handle 100 also includes at least two second locking members 10, wherein at least one second locking member 10 passes through the coupling 9 and abuts against the output shaft of the drive motor 1, and at least one second locking member 10 passes through the coupling 9 and abuts against the rotating part 2. In one embodiment of this utility model, please refer to... Figure 4 The second locking element 10 consists of two parts: one passes through the coupling 9 and abuts against the output shaft of the drive motor 1, and the other passes through the coupling 9 and abuts against the rotating part 2. By fixing the coupling 9 to the output shaft of the drive motor 1 and the rotating part 2 respectively using the second locking element 10, the rigidity of the entire transmission system can be enhanced, reducing potential loosening under high loads or impacts. In other embodiments, the second locking element 10 consists of four parts: two pass through the coupling 9 and abut against the opposite sides of the output shaft of the drive motor 1, and the other two pass through the coupling 9 and abut against the opposite sides of the rotating part 2.

[0047] For ease of connection of transducer 16, please refer to one embodiment of this utility model. Figure 3 and Figure 6 The handle 100 also includes a magnet 11, which is located at the end of the connecting rod 4 away from the drive motor 1. The magnet 11 is used for magnetic connection with the transducer 16 of the treatment head. The magnetic connection allows for quick and easy connection and disconnection of the transducer 16, improving the convenience and efficiency of operation. Furthermore, the magnetic connection allows for easy switching between different models or configurations of the transducer 16, increasing the flexibility of the handle 100.

[0048] Furthermore, in one embodiment of this utility model, please refer to... Figure 2 The handle 100 also includes a motor mounting base 15, which has a rod extending in a first direction. The rod has a positioning protrusion, and the corresponding bracket 5 has a positioning groove.

The rod and the bracket 5 are then fixed with screws. The drive motor 1 is mounted on the motor mounting base 15, and the output end of the drive motor 1 passes through the motor mounting base 15 and is connected to the coupling 9.
