Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic therapeutic instruments, and in particular to a direct-drive imaging and therapeutic device. Background Art

[0002] Ultrasonic therapy devices, commonly used in the market for skin treatment and conditioning, use a transducer to focus ultrasound waves at a single point, generating high energy that acts on the skin's dermis and fascia, stimulating collagen proliferation and reorganization, tightening contours, and reducing wrinkles and firming the skin. These devices typically consist of a handle and a probe, with the therapeutic transducer in the probe emitting ultrasound waves to treat the skin. Common ultrasonic therapy devices only have a therapeutic transducer and lack an imaging transducer, or the images produced by the imaging transducer are out of sync. This makes it difficult for doctors to accurately assess the actual subcutaneous condition during treatment, making it difficult to control the energy and range of treatment, and preventing real-time, precise treatment.

[0003] At the same time, in order to ensure the efficiency of treatment and reduce the workload of users, some ultrasonic therapeutic devices will set the treatment transducer to be movable. The driving member in the handle can drive the transducer to move, which can increase the radiation area of ​​the ultrasonic wave. However, in the prior art, the driving motor and the transducer are not directly connected. Usually, an intermediate mechanism such as a guide rail is required for indirect connection, such as disclosed in patent No. 202021319422.2. This makes it easy to produce deviations and cause jams during the driving process. In addition, the position of the transducer after movement cannot be accurately controlled, making it impossible to accurately position and use it, and when it is used again after interruption, the position of the transducer cannot be reset and needs to be re-debugged, which brings inconvenience to use. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a direct-drive imaging and treatment device.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A direct-drive imaging and treatment device includes a detachably connected handle and probe, characterized in that: the handle has a built-in drive mechanism, the probe has a built-in transducer module, the drive mechanism has a rotor, the axis of the rotor is hollow and is threaded with a transmission rod, the top of the transducer module has a connecting rod, the transmission rod is coaxial with the connecting rod and is detachably connected to the connecting rod, the rotor drives the transmission rod by rotation to directly drive the transducer module to synchronously perform linear reciprocating motion, and the end of the transducer module near the transmission window of the probe is provided with an imaging transducer and a treatment transducer.

[0007] Preferably, a permanent magnet is provided at each end of the connecting rod and the end of the transmission rod, and the connecting rod and the transmission rod are magnetically connected.

[0008] Preferably, a guide rod is provided in the probe, the extension direction of which is consistent with the moving direction of the transducer module, and the transducer module is slidably sleeved on the guide rod.

[0010] Preferably, a first elastomer and a second elastomer are respectively provided on both sides of the top of the transducer module, the extension direction of the first elastomer and the second elastomer is consistent with the movement direction of the transducer module, and wavy wrinkles are formed on the surfaces of the first elastomer and the second elastomer, so that the first elastomer and the second elastomer can expand and contract synchronously with the movement of the transducer module.

[0011] Preferably, the second elastic body is sleeved on the connecting rod.

[0012] Preferably, a bracket is provided in the handle, the driving mechanism is provided on the bracket, and a detection mechanism for detecting the movement position of the transmission rod is provided on the driving mechanism.

[0013] Preferably, the detection mechanism includes a linear code disk, an encoder, a sliding member and a controller. The linear code disk is fixed on the sliding member, and the sliding member is fixed to the tail end of the transmission rod so that the linear code disk moves synchronously with the transmission rod. The encoder is arranged on the bracket and electrically connected to the controller. The controller controls the operation of the driving mechanism. The linear code disk sliding card is arranged in the encoder, and marking lines are respectively provided at both ends of the linear code disk. The encoder controls the reciprocating movement of the transmission rod by detecting the marking lines.

[0014] Preferably, the sliding member is provided with at least one sliding groove, and a positioning block matching the sliding groove is fixedly connected to the bracket, and the positioning block is slidably clamped in the sliding groove.

[0015] Preferably, the detection mechanism includes an electrically connected photoelectric sensor and a controller, the photoelectric sensor is fixed on the bracket, the transmission rod is passed between the light emitting end and the light receiving end of the photoelectric sensor, and the transmission rod is located on the same horizontal line as the light emitting end and the light receiving end, and a group of through holes are provided on the transmission rod along its extension direction to allow the light beam emitted by the light emitting end to pass through, and the controller controls the operation of the driving mechanism.

[0016] The beneficial effects of the present invention are mainly reflected in:

[0017] 1. The transmission rod and the connecting rod of the transducer module are detachably connected by magnetism. This allows for convenient assembly and disassembly. On the other hand, the drive mechanism can be directly connected to the transducer module through the transmission rod to drive the transducer module to perform linear reciprocating motion without the need for other transmission parts. This ensures the smooth movement of the driven transducer module and avoids unnecessary noise and wear caused by connection deviations. At the same time, the radial play of the transmission rod of the direct drive is reduced compared to the indirect drive, which can ensure that the motor-driven transducer remains in a straight line during high-speed reciprocating motion, allowing the transducer to collect image signals and apply treatment at the same horizontal depth of the patient's skin.

[0025] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0026] In the description of the scheme, it should be noted that the terms "center", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0027] like Figures 1 to 5 As shown, the present invention discloses a direct-drive imaging and treatment device, comprising a detachably connected handle 1 and probe 2. The handle 1 has a built-in drive mechanism 3, and the probe 2 has a built-in transducer module 5. The drive mechanism 3 has a rotor 301, the axis of which is hollow and threaded with a transmission rod 302. The top of the transducer module 5 has a connecting rod 503, which is coaxial and detachably connected to the connecting rod 503. The rotor 301 rotates and drives the transmission rod 302 to directly drive the transducer module 5 to perform synchronous linear reciprocating motion. The end of the transducer module 5 near the transmission window of the probe 2 is provided with an imaging transducer 501 and a treatment transducer 502. The arrangement of the imaging transducer 501 and the treatment transducer 502 enables simultaneous imaging during treatment, helping the user accurately judge the actual subcutaneous conditions during treatment and facilitating control of the energy and range of treatment.

[0028] Specifically, the top of the transducer module 5 has a connecting rod 503, and the connecting rod 503 is integrally formed with the transducer module 5 to ensure the consistency of transmission. Such a structure enables the driving mechanism 3 to be directly connected to the transducer module 5 through the transmission rod 302 to drive the transducer module 5 to perform linear reciprocating motion. Such a direct drive structure can simplify the internal structure without the need to convert it into linear movement through other components, so that there is a high consistency between the transmission rod 302 and the transducer module 5, which can ensure the smoothness of driving the transducer module 5 to move, and avoid unnecessary noise and wear caused by deviation or jamming in the connection. The transmission rod 302 only needs to add grease at the connection of its threaded surface to reduce the friction coefficient and reduce the wear between it and the rotor itself, thereby increasing its service life; in addition, direct drive can make the drive mechanism 3 and the transmission rod 302 on the same horizontal line, so that the radial movement of the transmission rod 302 is smaller than that of indirect drive, which can ensure that the transducer module 5 remains in a straight line during high-speed reciprocating motion, so that the transducer module 5 can collect image signals and apply treatment at the same horizontal depth of the patient's skin.

[0029] In a preferred embodiment, a permanent magnet 6 is provided at each end of the connecting rod 503 and the end of the transmission rod 302, and the connecting rod 503 and the transmission rod 302 are magnetically connected. The connecting rod 503 and the transmission rod 302 are detachably connected via magnetism. In other feasible embodiments, the connecting rod 503 and the transmission rod 302 can also be detachably connected using other feasible methods well known to those skilled in the art, such as by providing a snap fastener for engagement.

[0030] Furthermore, the probe 2 is provided with a guide rod 7 extending in the same direction as the movement direction of the transducer module 5, and the transducer module 5 is slidably mounted on the guide rod 7. The provision of the guide rod 7 can limit the movement direction of the transducer module 5. The cross-section of the guide rod 7 is preferably rectangular to prevent the transducer module 5 from shaking or deflecting, ensuring that the imaging transducer 501 and the therapeutic transducer 502 at the ends of the transducer module 5 remain aligned with the transmission window of the probe 2. In other feasible embodiments, the cross-section of the guide rod 7 can also have other non-circular structures, such as triangles or polygons.

[0031] like Figure 2As shown, a first elastic body 8 and a second elastic body 9 are respectively provided on both sides of the top of the transducer module 5. The extension direction of the first elastic body 8 and the second elastic body 9 is consistent with the movement direction of the transducer module 5, and the surfaces of the first elastic body 8 and the second elastic body 9 are formed with wavy wrinkles, so that the first elastic body 8 and the second elastic body 9 can expand and contract synchronously with the movement of the transducer module 5. The first elastic body 8 and the second elastic body 9 are preferably bellows made of silicone material, which can generate elastic force on the transducer module 5 through deformation, so as to facilitate the rapid reset of the transducer module 5 and ensure the stability of the movement of the transducer module 5.

[0032] The two ends of the first elastomer 8 are arranged between the inner wall of the handle 1 and the top of the transducer module 5, and the second elastomer 9 is arranged at the top of the transducer module 5 and the tail end of the connecting rod 503, and the second elastomer 9 is sleeved on the connecting rod 503, which can save space on the one hand and protect the connecting rod 503 on the other hand.

[0033] The handle 1 is provided with a bracket 10, and the drive mechanism 3 is provided on the bracket 10. The drive mechanism 3 is preferably a fixed-axis stepper motor. The drive mechanism 3 is provided with a detection mechanism 4 for detecting the movement position of the transmission rod 302. The detection mechanism 4 controls the movement of the drive mechanism 3 by detecting the position of the transmission rod 302 in real time, thereby achieving precise positioning of the transducer module 5.

[0034] Since the driving mechanism 3 is a fixed-axis stepping motor, the movement mode of the driving mechanism 3 is acceleration-constant speed-deceleration. This results in the problem that the imaging and treatment points of the transducer module 5 are dense on both sides and sparse in the middle when the transducer module 5 is not under the control of the detection mechanism 4. The setting of the detection mechanism 4 allows the driving mechanism 3 to control the transmission rod 302 to drive the transducer module 5 to move to a specified point through the monitoring of the detection mechanism 4. The entire stroke of the transducer module 5 can be divided into several equidistant points. Fixed-point pulse imaging and treatment are performed by detecting feedback from different points, thereby ensuring that the pulse imaging and treatment points of the transducer module 5 remain consistent in the acceleration section, uniform speed section, and deceleration section, thereby achieving the purpose of improving the imaging and treatment quality, helping the user to judge the imaging site, and also facilitating accurate positioning or restoration during use or after interruption.

[0035] Specific examples Figure 1-3The figure shows a first embodiment of the detection mechanism 4, which includes a linear code disk 401, an encoder 402, a sliding member 403 and a controller 404. The linear code disk 401 is fixed on the sliding member 403, and the sliding member 403 is fixed to the tail end of the transmission rod 302, so that the linear code disk 401 and the transmission rod 302 move synchronously. The encoder 402 is set on the bracket 10 and is electrically connected to the controller 404. The controller 404 controls the operation of the driving mechanism 3. The linear code disk 401 is slidably clamped in the encoder 402, and marking lines 405 are respectively provided at both ends of the linear code disk 401. The encoder 402 controls the reciprocating movement of the transmission rod 302 by detecting the marking lines 405.

[0036] The linear code disk 401 is a standard linear encoder tape with various resolutions and lengths, made of polyester film. The encoder 402 is compatible with the linear code disk 401. As the linear code disk 401 reciprocates, it detects its position in real time and outputs a position signal to the controller 406, which controls the operation of the drive mechanism 3. When the encoder 402 detects the marking lines 405 at either end, the controller 406 controls the drive mechanism 3 to reverse direction, achieving the reciprocating linear motion of the transmission rod 302. This structure allows the transducer module 5 to be pre-set and precisely positioned at the pre-set position for imaging and treatment. Furthermore, upon completion of imaging or treatment, or in the event of an unexpected power outage, the drive mechanism 3 can be controlled to return to its initial position by detecting the marking lines 405 on the linear code disk 401.

[0037] Furthermore, at least one slide groove 406 is provided on the sliding member 403, and a positioning block 407 matching the slide groove 406 is fixedly connected to the bracket 10, and the positioning block 407 is slidably clamped in the slide groove 406. In the illustrated embodiment, two groups of the slide grooves 406 and positioning blocks 407 are provided on the sliding member 402 to enhance the smoothness of the movement of the sliding member 403. The positioning block 407 can be any block that can match the slide groove 406. In a preferred embodiment, the positioning block 407 is a shoulder bolt to facilitate loading and unloading. The sliding member 403 is made of a material with good lubricity, such as Teflon added to polyoxymethylene, to reduce the friction noise and wear generated between it and the positioning block 407, thereby ensuring the smoothness and bass of the sliding of the sliding member 403.

[0038] like Figure 4-5The figure shows a second embodiment of the detection mechanism 4. In the second embodiment, the detection mechanism 4 includes an electrically connected photoelectric sensor 408 and a controller 404. The photoelectric sensor 408 is fixed to the bracket 10. The transmission rod 302 is disposed between the light emitting end 409 and the light receiving end 410 of the photoelectric sensor 408, and the transmission rod 302 is located on the same horizontal line as the light emitting end 409 and the light receiving end 410. The transmission rod 302 is provided with a set of through holes 303 along its extension direction to allow the light beam emitted by the light emitting end 409 to pass through. The controller 404 controls the operation of the driving mechanism 3.

[0039] Its working principle is as follows: when the driving mechanism 3 drives the transmission rod 302 to perform reciprocating linear motion, when the through hole 303 on the transmission rod 302 is directly opposite to the light emitting end 409, the light beam emitted by the light emitting end 409 will pass through the through hole 303 to the light receiving end 410. At this time, after receiving the light beam, the light receiving end 410 will send a position signal to the controller 406. By judging the number of received light beams, the number of through holes 303 passed through is judged, thereby judging the displacement of the transmission rod 302 to determine the position of the transducer module 5.

[0040] In the second embodiment, the through holes 303 are evenly distributed on the transmission rod 302 with the same size. In other feasible embodiments, the diameters of the through holes 303 may be inconsistent, and the through holes 303 may be arranged at unequal distances. The inconsistent diameters and shapes of the through holes 303 change the intensity of the light beam passing through, so that the light receiving end 410 can determine the position of the through hole 303 after receiving the light, thereby determining the position of the transmission rod 302.

[0041] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation method can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0042] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
