Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a treatment head, treatment handpiece, and ultrasonic therapy device. Background Technology

[0002] There are many ultrasound cosmetic devices on the market. The treatment principle is to use focused ultrasound to strike subcutaneous tissue at a fixed depth to achieve cosmetic effects. Usually, these devices can only strike a fixed point or can move left and right to strike different points along a line.

[0003] The above devices have the following drawbacks in actual use scenarios: due to the large differences between individuals, the depth of impact cannot be adjusted, which requires multiple treatment heads with different depths, increasing the cost of the treatment heads; while existing treatment heads that can adjust the treatment depth require the movement module in one direction to move together with the movement module in another direction, which is more complex in structure and increases the load on the movement module. Utility Model Content

[0004] The main purpose of this invention is to propose a treatment head, treatment handpiece, and ultrasound therapy device, which aims to enable the transducer assembly to perform two-dimensional motion in the vertical plane, and the motion modules in the horizontal direction are relatively independent from those in the vertical direction.

[0005] To achieve the above objectives, the present invention provides a treatment head comprising a housing, a main support, a lifting support, and a transducer assembly. The main support is installed within the housing. The lifting support is slidably connected to the main support, and an external first driving mechanism is used to drive the lifting support to move vertically relative to the main support. The transducer assembly is slidably connected to the lifting support, and an external second driving mechanism is used to drive the transducer assembly to move horizontally relative to the lifting support.

[0006] In one embodiment, the lifting support includes a first guide post extending along the horizontal direction, and the transducer assembly includes a guide hole through which the first guide post passes. The first guide post and the guide hole are used to guide the movement of the transducer assembly relative to the lifting support.

[0007] In one embodiment, the main support includes a second guide post extending toward the vertical direction. The lifting support has a limiting hole, and the second guide post is at least partially inserted into the limiting hole. The second guide post and the limiting hole are used to guide the movement of the lifting support relative to the main support along the vertical direction.

[0008] In one embodiment, the number of the second guide posts is at least two, and the number of the limiting holes matches the number of the second guide posts.

[0009] In one embodiment, the treatment head further includes a drive shaft, one end of which is slidably connected to the transducer assembly in a vertical direction, and the other end of which is exposed in the housing for connection to the external second drive mechanism.

[0010] In one embodiment, the treatment head further includes a sealing tube sleeved on the drive shaft, with both ends of the sealing tube telescopically connected between the transducer assembly and the housing.

[0011] In one embodiment, the lifting bracket has an elongated hole, and the other end of the drive shaft passes through the elongated hole and the housing and is connected to the external second drive mechanism.

[0012] In one embodiment, the treatment head further includes a connector and two third guide posts in the horizontal direction. The connector is disposed on the transducer assembly. One end of the drive shaft is drivenly connected to the connector. The two third guide posts are parallel and spaced apart on the main support. The opposite sides of the connector in the horizontal direction are slidably connected to one of the third guide posts respectively.

[0013] This utility model also proposes a treatment hand, which includes a handle and a treatment head as described above. The handle includes a first drive mechanism and a second drive mechanism, and the handle is detachably connected to the treatment head.

[0014] This utility model also proposes an ultrasonic therapy device, which includes a main unit, a cable, and a treatment hand as described above. The treatment hand is detachably connected to the main unit via the cable.

[0015] The technical solution of this utility model adopts a lifting bracket that is slidably connected to the main support. The transducer assembly is slidably connected to the lifting bracket. An external first drive mechanism drives the lifting bracket to move vertically relative to the main support, and drives the transducer assembly to move vertically relative to the main support. An external second drive mechanism drives the transducer assembly to move horizontally relative to the lifting bracket. This enables the transducer assembly to perform two-dimensional movement relative to the vertical plane of the main support to adapt to different treatment depths and achieve precise treatment. The two sets of horizontal and vertical moving modules are relatively independent, reducing the load on the moving modules and making it easier to adjust the transducer assembly to the required position.

[0028] There are many ultrasound cosmetic devices on the market. The treatment principle is to use focused ultrasound to strike subcutaneous tissue at a fixed depth to achieve cosmetic effects. Usually, these devices can only strike a fixed point or can move left and right to strike different points along a line.

[0029] The above devices have the following drawbacks in actual use scenarios: due to the large differences between individuals, the depth of impact cannot be adjusted, which requires multiple treatment heads with different depths, increasing the cost of the treatment heads; while existing treatment heads that can adjust the treatment depth require the movement module in one direction to move together with the movement module in another direction, which is more complex in structure and increases the load on the movement module.

[0030] This invention proposes a treatment head and an ultrasound therapy device, aiming to enable the transducer assembly to perform two-dimensional motion in the vertical plane, and the motion modules in the horizontal direction are relatively independent from those in the vertical direction.

[0031] Please see Figures 1 to 5 In one embodiment of the present invention, the treatment head 100 includes a housing 7, a main support 1, a lifting support 2, and a transducer assembly 3. The main support 1 is installed inside the housing 7. The lifting support 2 is slidably connected to the main support 1, and an external first driving mechanism is used to drive the lifting support 2 to move vertically relative to the main support 1. The transducer assembly 3 is slidably connected to the lifting support 2, and an external second driving mechanism is used to drive the transducer assembly 3 to move horizontally relative to the lifting support 2.

[0032] In this embodiment, the housing 7, main support 1, and lifting support 2 can all be made of rigid plastic, which is sturdy and durable, and has a certain degree of self-lubrication to ensure smooth sliding. The housing 7 adopts a flat rectangular shape, which can accommodate the moving modules in two directions, and the structure is more compact, making the treatment head 100 more miniaturized overall. The main support 1 and lifting support 2 have similar structures, both being frame-like structures, including a main board and two side plates set on opposite sides of the main board. The transducer assembly 3 can move within the space enclosed by the frame-like structure. The lifting support 2 can be fitted onto the outside of the two side plates of the main support 1 through the two side plates, allowing the lifting support 2 to slide relative to the main support 1. The lifting support 2 can also be sandwiched between the two side plates of the main support 1 through the two side plates, allowing the lifting support 2 to slide relative to the main support 1 as well. No further limitation is made here. The main support 1 is connected to the housing 7, or can be part of the housing 7, allowing the lifting support 2 to move vertically relative to the main support 1 or relative to the housing 7.

[0033] The technical solution of this utility model adopts a lifting bracket 2 that is slidably connected to the main bracket 1, and a transducer assembly 3 that is slidably connected to the lifting bracket 2. An external first drive mechanism drives the lifting bracket 2 to move vertically relative to the main bracket 1, and drives the transducer assembly 3 to move vertically relative to the main bracket 1. An external second drive mechanism drives the transducer assembly 3 to move horizontally relative to the lifting bracket 2, so that the transducer assembly 3 can perform two-dimensional movement relative to the vertical plane of the main bracket 1 to adapt to different treatment depths and achieve precise treatment. The two sets of horizontal and vertical moving modules are relatively independent, reducing the load on the moving modules and making it easier to adjust the transducer assembly 3 to the required position.

[0034] In an embodiment of this utility model, the lifting bracket 2 includes a first guide post 11, which extends horizontally, and the transducer assembly 3 includes a guide hole 1121, in which the first guide post 11 passes. The first guide post 11 and the guide hole 1121 are used to guide the movement of the transducer assembly 3 relative to the lifting bracket 2.

[0035] In this embodiment, the first guide post 11 can be made of hard plastic, which is sturdy and durable, and has a certain degree of self-lubrication to ensure smooth sliding. The transducer assembly 3 is slidably connected to the first guide post 11 through the guide hole 1121, which restricts the movement direction of the transducer assembly 3, making the horizontal movement of the transducer assembly 3 more stable and reliable, and preventing the transducer assembly 3 from deviating in the horizontal direction, thereby affecting the treatment position of the treatment head 100.

[0036] In an embodiment of this utility model, the main support 1 includes a second guide post 12 extending in a vertical direction. The lifting support 2 has a limiting hole 21, and the second guide post 12 is at least partially inserted into the limiting hole 21. The second guide post 12 and the limiting hole 21 are used to guide the lifting support 2 to move in a vertical direction relative to the main support 1.

[0037] In this embodiment, the main support 1 is provided with a second guide post 12 extending in the vertical direction, and the lifting support 2 is provided with a limiting hole 21. The second guide post 12 is at least partially inserted in the limiting hole 21. The lifting support 2 can move in the vertical direction relative to the main support 1 along the extension direction of the second guide post 12. The cooperation between the second guide post 12 and the limiting hole 21 guides the vertical movement of the lifting support 2 and also limits the position of the lifting support 2 relative to the main support 1 to prevent the movement from deviating.

[0038] In one example, the limiting hole 21 on the lifting bracket 2 is located on the body of the lifting bracket 2, allowing the body of the lifting bracket 2 to move vertically along the extension direction of the second guide post 12. It is understood that in another embodiment, the first guide post 11 further includes a column 111 and two first guide sleeves 112. Each first guide sleeve 112 has a limiting hole 21 that slides onto the second guide post 12. The two ends of the first guide sleeve 112 are respectively used to connect to the lifting bracket 2 and the column 111. The lifting bracket 2 drives the first guide sleeve 112 to slide relative to the second guide post 12, thereby driving the transducer assembly 3 to slide relative to the second guide post 12. The first guide sleeve 112 can be made of rubber or silicone, possessing a certain degree of self-lubrication, making the sliding between the first guide post 11 and the second guide post 12 smoother. The first guide post 11 has a limiting hole 21 at each end. Through the cooperation between the limiting holes 21 at both ends and the second guide post 12, the first guide post 11 can slide along the extension direction of the second guide post 12, and drive the transducer assembly 3 to slide along the extension direction of the second guide post 12, so that the vertical sliding of the transducer assembly 3 can be more stable.

[0039] In an embodiment of this utility model, the number of second guide posts 12 is at least two, and the number of limiting holes 21 matches the number of second guide posts 12.

[0040] In this embodiment, there are at least two second guide posts 12, and both second guide posts 12 cooperate with the limiting holes 21 of the main body of the lifting bracket 2. The cooperation between the second guide posts 12 and the limiting holes 21 guides the vertical movement of the lifting bracket 2 and also limits the position of the lifting bracket 2 relative to the main bracket 1, preventing deviation of movement. It can be understood that in another embodiment, some of the second guide posts 12 cooperate with the limiting holes 21 of the main body of the lifting bracket 2, and the remaining second guide posts 12 cooperate with the limiting holes 21 of the first guide sleeve 112, so that the first guide post 11 can slide along the extension direction of the second guide post 12.

[0041] In an embodiment of this utility model, the treatment head 100 further includes a drive shaft 4, one end of which is slidably connected to the transducer assembly 3 in the vertical direction, and the other end of which is exposed in the housing 7 for connection with an external second drive mechanism.

[0042] In this embodiment, a drive shaft 4 partially exposed in the housing 7 is provided on the treatment head 100. One end of the drive shaft 4 is connected to the transducer assembly 3 in the vertical direction, so that the transducer assembly 3 can move in the vertical direction relative to the drive shaft 4. The other end of the drive shaft 4 is used to connect to an external second drive mechanism. The external second drive mechanism drives the transducer assembly 3 to move in the horizontal direction along the first guide post 11 through the drive shaft 4.

[0043] In an embodiment of this utility model, the treatment head 100 further includes a sealing tube 5, which is sleeved on the drive shaft 4, and the two ends of the sealing tube 5 are telescopically connected between the transducer assembly 3 and the housing 7.

[0044] In this embodiment, a sealing tube 5 is sleeved around the outer periphery of the drive shaft 4, and both ends of the sealing tube 5 are telescopically connected between the transducer assembly 3 and the housing 7. The drive shaft 4 essentially pushes or pulls the transducer assembly 3 along the extension direction of the first guide post 11 by the telescopic movement of the sealing tube 5. This improves the overall sealing performance of the treatment head 100.

[0045] In an embodiment of this utility model, the lifting bracket 2 has an elongated clearance hole, and the other end of the drive shaft 4 passes through the clearance hole and the housing 7 to connect with the external second drive mechanism.

[0046] In an embodiment of this utility model, the lifting bracket 2 has an elongated hole 22, and the other end of the drive shaft 4 passes through the elongated hole 22 and the housing 7 and is connected to the external second drive mechanism.

[0047] In this embodiment, the lifting bracket 2 has an elongated hole 22 that extends vertically. The other end of the drive shaft 4 passes through the elongated hole 22 and the housing 7 and is connected to the external second drive mechanism. The lifting bracket 2 can move vertically relative to the drive shaft 4, making the vertical movement of the lifting bracket 2 more stable.

[0048] In an embodiment of this utility model, the treatment head 100 further includes a connector 6 and two third guide posts 13 along the horizontal direction. The connector 6 is disposed on the transducer assembly 3, and one end of the drive shaft 4 is drivenly connected to the connector 6. The two third guide posts 13 are parallel and spaced apart on the main support 1, and the opposite sides of the connector 6 in the horizontal direction are slidably connected to a third guide post 13 respectively.

[0049] In this embodiment, the treatment head 100 further includes two third guide posts 13 and a connector 6. The connector 6 is sleeved on the other end of the transducer bracket away from the ultrasonic transducer. The opposite sides of the connector 6 are slidably connected to a third guide post 13, and the extending directions of the two third guide posts 13 are the same as the extending directions of the first guide post 11. When the transducer assembly 3 moves relative to the extending direction of the first guide post 11, the opposite sides of the connector 6 also move relative to the extending directions of the two third guide posts 13. The triangular guiding structure formed by the first guide post 11 and the two third guide posts 13 makes the horizontal movement of the transducer assembly 3 more stable, thereby improving the treatment accuracy of the treatment head 100.

[0050] This utility model also proposes a treatment hand, which includes a handle and a treatment head 100 as described above. The handle includes a first drive mechanism and a second drive mechanism, and the handle is detachably connected to the treatment head 100.

[0051] In this embodiment, the handle is detachably connected to the treatment head 100. The handle is provided with a first drive mechanism and a second drive mechanism. The second drive mechanism drives the transducer assembly 3 to move horizontally relative to the lifting bracket 2, and the first drive mechanism drives the lifting bracket 2 to move the transducer assembly 3 vertically, thereby achieving the effect of two-dimensional movement on the vertical plane where the lifting bracket 2 is located. Both drive components are located outside the treatment head 100, making the treatment head 100 as a whole miniaturized.

[0052] This utility model also proposes an ultrasonic therapy device, which includes a main unit, a cable, and a treatment handpiece as described above. The treatment handpiece is detachably connected to the main unit via the cable.

[0053] In this embodiment, the transducer assembly 3 of the treatment head 100 in the treatment handpiece is electrically connected to the main unit via a cable, and can convert electrical energy into sound energy for ultrasonic therapy.
