Adjustable focusing depth ultrasonic transmitter structure

Abstract

An adjustable-depth-of-focus ultrasound transmitter structure includes a transmission unit and an ultrasound transmitting unit. The transmission unit has a transmission push rod. The ultrasound transmitting unit is connected to the transmission unit. The ultrasound transmitting unit defines an axis corresponding to the direction of the transmission push rod. The ultrasound transmitting unit is driven by the transmission push rod to move along the axis, thereby adjusting the axial distance between the ultrasound transmitting unit and the transmission unit. This allows the adjustable-depth-of-focus ultrasound transmitter structure to adjust the depth at which the ultrasound waves of the ultrasound transmitting unit are focused on the subcutaneous tissue of the human skin, allowing the ultrasound waves of the ultrasound transmitting unit to focus more deeply into the subcutaneous tissue of the skin, thus improving the effect of skin tissue repair.

Description

[Technical Field]

[0001] This invention relates to ultrasonic structure technology; in particular, it refers to an ultrasonic transmitter structure with adjustable focusing depth. [Previous Technology]

[0002] Focused ultrasound technology is a commonly used skin repair technology. This focused ultrasound system is used to focus the energy of ultrasound waves on the subcutaneous tissue of the human body, which can effectively promote the proliferation of collagen in the skin and also provide the effect of repairing subcutaneous tissue.

[0003] Currently, existing focused ultrasound instruments typically have a horizontal drive mechanism inside, which is connected to the ultrasound transmitter. The horizontal drive mechanism can drive the ultrasound transmitter to make horizontal displacement, so that the ultrasound transmitter can emit ultrasound waves during the horizontal displacement process, providing the user with the function of controlling the ultrasound transmitter to move to a specified skin area. Although the horizontal drive mechanism of the focused ultrasound instrument can drive the ultrasound transmitter to move horizontally, since the existing ultrasound transmitters are all fixed structures and do not have axial movement function, the ultrasound transmitter cannot provide the effect of adjusting the focused depth for subcutaneous tissue. [Summary of the Invention]

[0004] In view of this, the purpose of the present invention is to provide an ultrasonic transmitter structure with adjustable focusing depth, which can adjust the axial displacement of the ultrasonic transmitter to adjust the depth of ultrasonic focusing on human subcutaneous tissue.

[0005] In order to achieve the above objectives, the present invention provides an adjustable focusing depth ultrasonic transmitter structure, including a transmission unit and an ultrasonic transmitting unit; the transmission unit has a transmission push rod; the ultrasonic transmitting unit is connected to the transmission unit, and the ultrasonic transmitting unit defines an axis corresponding to the direction of the transmission push rod, and the ultrasonic transmitting unit is driven by the transmission push rod to move along the axis.

[0006] In one embodiment, the ultrasonic emitting unit has a fixed base and an ultrasonic emitting part. The fixed base is connected to the transmission push rod, and the ultrasonic emitting part is mounted on the fixed base. The fixed base has an installation section and a connecting section along the axial direction. The ultrasonic emitting part is disposed on one side of the installation section, and the connecting section is located on the other side of the installation section and is connected to the transmission push rod.

[0007] In one embodiment, the transmission unit has a driven block and a connecting piece. The driven block is disposed on the transmission push rod. The connecting piece is assembled with the driven block and extends in the direction of the ultrasonic transmitting unit corresponding to the transmission push rod. The connecting piece is located on one side of the transmission push rod. The ultrasonic transmitting unit has a fixed base and an ultrasonic transmitting part. The ultrasonic transmitting part is installed on one side of the fixed base. A connecting block protrudes from the other side of the fixed base. The connecting block is assembled with the connecting piece.

[0008] The effect of the present invention is that when the transmission unit drives the transmission push rod, the transmission push rod can move the ultrasonic emitting unit along the axis to adjust the axial distance between the ultrasonic emitting unit and the transmission unit. In this way, the ultrasonic emitting unit with adjustable focusing depth can adjust the depth at which the ultrasonic waves of the ultrasonic emitting unit are focused on the subcutaneous tissue of the skin, so that the ultrasonic waves of the ultrasonic emitting unit can be more deeply focused on the subcutaneous tissue of the skin, thereby improving the effect of repairing skin tissue.

Implementation Method

[0009] To more clearly illustrate the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. Please refer to Figures 1 and 2, which show an adjustable focusing depth ultrasonic transmitter structure 100 provided in the first preferred embodiment of the present invention, comprising a housing 10, a transmission unit 20, an ultrasonic transmitting unit 30, and a telescopic sleeve 40.

[0010] The housing 10 is connected to the transmission unit 20 and is used to fix the transmission unit 20. In the first embodiment, as shown in FIG2 and 3, the housing 10 has a receiving groove 11, a receiving opening 12 and a fixing plate 13. The inner side of the receiving groove 11 is provided with a slot 14 from the receiving opening 12. Viewed from FIG2, the receiving opening 12 faces the transmission unit 20 and is located on the top surface of the housing 10. The fixing plate 13 is inserted into the slot 14 from the receiving opening 12 and is positioned in the receiving groove 11.

[0011] The transmission unit 20 is installed in the housing 10. In the first embodiment, the drive source of the transmission unit 20 is a stepper motor, as shown in Figures 3 and 4. The transmission unit 20 has a transmission push rod 21, a driven block 22, a connecting piece 23, and a fixed side frame 24. The transmission push rod 21 is connected to the drive source (not shown in the figure). The driven block 22 is disposed on the transmission push rod 21. The driven block 22 is driven by the transmission push rod 21 to perform axial displacement. The connecting piece 23 is assembled with the driven block 22 and... The transmission push rod 21 extends toward the ultrasonic transmitting unit 30, and the connecting piece 23 is located on one side of the transmission push rod 21. The fixed side bracket 24 is disposed on the other side of the transmission push rod 21 opposite to the connecting piece 23, as shown in Figures 3-6. When the transmission unit 20 is installed in the housing 10, the fixed side bracket 24 of the transmission unit 20 is locked to the fixing plate 13 of the housing 10, so that the transmission unit 20 is fixed in the receiving groove 11 of the housing 10, and the connecting piece 23 extends out of the receiving opening 12.

[0012] The ultrasonic emitting unit 30 is connected to the transmission unit 20. The ultrasonic emitting unit 30 defines an axis L corresponding to the direction of the transmission push rod 21. The ultrasonic emitting unit 30 is driven by the transmission push rod 21 to move along the axis L, as shown in Figures 4-6. In the first embodiment, the ultrasonic emitting unit 30 has a fixed base 31 and an ultrasonic emitting part 32. The ultrasonic emitting part 32 is mounted on one side of the fixed base 31. The other side of the fixed base 31 protrudes from the transmission unit 20 with a set of... The set of connecting blocks 311 and an annular wall 312 are connected to the connecting piece 23 along the axis L. The annular wall 312 surrounds the set of connecting blocks 311. When the transmission unit 20 drives the transmission push rod 21, the transmission push rod 21 moves the fixed seat 31 of the ultrasound emitting unit 30 along the axis L through the driven block 22 and the connecting piece 23, thereby adjusting the axial distance between the ultrasound emitting unit 30 and the transmission unit 20 and providing the effect of adjusting the depth of the ultrasound emitting unit 30 focusing on the subcutaneous tissue.

[0013] The telescopic sleeve 40 is connected between the ultrasonic transmitting unit 30 and the housing 10, as shown in Figures 3 to 5. The telescopic sleeve 40 is made of elastic material and has two fixed parts 41 and one telescopic part 42. The two fixed parts 41 are located at both ends of the telescopic sleeve 40, and the telescopic part 42 is connected between the two fixed parts 41. The two ends of the telescopic sleeve 40 are connected to the annular wall 312 of the fixed seat 31 and the receiving opening 12 of the housing 10 through the two fixed parts 41. The telescopic part 42 surrounds the connection between the connecting block 311 and the connecting piece 23. The ultrasonic transmitting unit 30 is driven by the transmission unit 20 to move and correspondingly pull the telescopic part 42 to extend and retract, so as to protect the connecting block 311, the transmission push rod 21 and the connecting piece 23 from external environmental interference.

[0014] In other embodiments, the ultrasonic transmitter structure 100 with adjustable focusing depth can change its overall structure as needed. For example, the transmission unit 20 and the ultrasonic transmitter 30 are not limited to being matched with the housing 10 and the telescopic sleeve 40, as long as the transmission unit 20 can drive the ultrasonic transmitter 30 to move axially; the transmission unit 20 is not limited to having the driven block 22, the connecting piece 23 and the fixed side frame 24, and can also be connected to the ultrasonic transmitter 30 through other linkage mechanisms; or the ultrasonic transmitter 30 can adjust the form of the fixed base 31.

[0015] Figures 7 and 8 show that the adjustable focusing depth ultrasonic transmitter structure 100 is applied to an ultrasonic probe 200. The ultrasonic probe 200 includes a control element 210 and a housing element 220. The control element 210 has a drive unit 2101, a horizontal guide rod 2102, and a mounting base 2103 inside. The drive unit 2101 is connected to the horizontal guide rod 2102, and the mounting base 2103 is disposed on the horizontal guide rod 2102 and connected to the drive unit 2101, thereby driving... The part 2101 can drive the mounting base 2103 to move laterally along the horizontal guide rod 2102, wherein the ultrasonic transmitter structure 100 with adjustable focusing depth is longitudinally arranged on the mounting base 2103 relative to the horizontal guide rod 2102, the cover element 220 combines the control element 210, and the cover element 220 covers the ultrasonic transmitter structure 100 with adjustable focusing depth, and the cover element 220 has an irradiation port 2201 corresponding to the ultrasonic emitting part 32 of the ultrasonic emitting unit 30.

[0016] As shown in Figure 8, when the ultrasound probe 200 actually irradiates the skin 1 of a human body, the irradiation port 2201 of the housing element 220 faces the skin 1. The ultrasound emitting unit 30 of the adjustable-focus-depth ultrasound emitter structure 100 emits ultrasound waves to the skin 1 through the irradiation port 2201. The user can control the drive unit 2101 to drive the mounting base 2103 and the adjustable-focus-depth ultrasound emitter structure 100 to perform horizontal displacement according to the area of ​​the skin 1 to be irradiated, through the control element 210. The user can also control the... The transmission unit 20 of the adjustable-focusing-depth ultrasound emitter structure 100 drives the ultrasound emitter 30 to make axial displacement, thereby adjusting the depth at which the ultrasound waves of the ultrasound emitter 30 are focused on the subcutaneous tissue of the skin 1. For example, the transmission unit 20 can drive the ultrasound emitter 30 to move towards the irradiation port 2201 of the cover element 220, so that the ultrasound waves of the ultrasound emitter 30 are focused on the subcutaneous tissue of the skin 1 at a depth of 1.5~5mm, allowing the ultrasound waves of the ultrasound emitter 30 to be more deeply focused on the subcutaneous tissue of the skin 1, thereby improving the effect of repairing the subcutaneous tissue of the skin 1.

[0017] Please also refer to Figures 9 and 10, which show the adjustable focusing depth ultrasonic transmitter structure 300 provided in the second preferred embodiment of the present invention, including a housing 50, a transmission unit 60, an ultrasonic transmitting unit 70 and a telescopic sleeve 80.

[0018] The housing 50 is connected to the transmission unit 60 and is used to fix the transmission unit 60. In the second embodiment, as shown in FIG10 and FIG11, the housing 50 has a receiving groove 51, a receiving port 52 and a side opening 53. The receiving port 52 and the side opening 53 are respectively connected to the receiving groove 51. Viewed from FIG10, the receiving port 52 faces the transmission unit 60 and is located on the top surface of the housing 50. The side opening 53 is located on the side of the housing 50 and is connected to the receiving port 52. The side opening 53 is for the transmission unit 60 to be guided into the receiving groove 51.

The adjusting nut 63 and the fixing nut 64 are respectively sleeved on the threaded portion 62, as shown in Figures 2 and 5. When the transmission unit 60 is disposed in the receiving groove 51, the fixing nut 64 is located in the receiving groove 51 and abuts against one side of the receiving opening 52. The transmission push rod 61 and the adjusting nut 63 extend out of the receiving opening 52, and the adjusting nut 63 abuts against the other side of the receiving opening 52 relative to the fixing nut 64, so that the transmission unit 60 is fixed on the housing 50.

On the transmission push rod 61, the connecting section 75 connects the mounting section 73 and the connecting section 74. The connecting section 75 has a hollow groove 751 inside. The mounting section 73 has a wire hole 731 that connects to the hollow groove 751. The connecting section 75 has a side cut surface 752. The side cut surface 752 forms a side opening 753 to connect to the hollow groove 751. The wire of the ultrasonic emitting unit 72 can be led out through the wire hole 731 of the mounting section 73 and the side opening 753 of the connecting section 75. When the transmission unit 60 drives the transmission push rod 61, the transmission push rod 61 can directly drive the fixed seat 71 of the ultrasonic emitting unit 70 to move along the axis L', thereby adjusting the axial distance between the ultrasonic emitting unit 70 and the transmission unit 60, and achieving the effect of adjusting the depth of the ultrasonic waves of the ultrasonic emitting unit 70 focused on the subcutaneous tissue.

[0021] The telescopic sleeve 80 is connected between the transmission unit 60 and the ultrasonic emitting unit 70, as shown in Figures 11-13.
