Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0033] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] In existing technologies, laser therapy devices utilize a laser 400 to emit laser light, which is then output from the working tip 700 to treat the corresponding location. However, the power of the existing laser 400 is generally fixed, making it impossible to adjust it according to real-time conditions during operation, resulting in inconvenient operation. Furthermore, it is impossible to intuitively obtain the operating parameters of the laser 400, further complicating control.

[0036] In view of this, the designers have provided a controllable digital display laser therapy instrument handle that can adjust the output power of the laser 400 as needed to adapt to different scenario requirements, making it flexible and reliable to use. The operator can also intuitively obtain the working parameter information of the laser 400, which can provide reliable data support for adjusting the working status of the laser 400, making the adjustment of the laser 400 more accurate and efficient.

[0037] Please refer to Figures 1-4 This embodiment provides a controllable digital display laser therapy device handpiece, including:

[0038] The housing 100 includes a controller 200, a circuit board 300, a laser 400, a display screen 500, a control 600, and a working tip 700, all mounted on the housing 100. The control 600 is movably fitted with the housing 100. The working tip 700 is located at the front end 101 of the housing 100 and is connected to the laser 400.

[0039] The controller 200, laser 400, display screen 500 and adjustment control 600 are all electrically connected to the circuit board 300; the controller 200 is used to obtain the position information of the adjustment control 600 in order to control the output power of the laser 400 through the position information.

[0040] As described above, the working principle of the controllable digital display laser therapy instrument handpiece provided in this embodiment is as follows:

[0041] By installing an adjustment control 600 on the housing 100, the output power of the laser 400 can be adjusted as needed, allowing the laser therapy device to adapt to different usage scenarios. For example, when the output power of the laser 400 needs to be adjusted, the adjustment control 600 is operated, changing its position relative to the controller 200. The controller 200 generates a corresponding control signal based on the real-time position information of the adjustment control 600, using this control signal to control the output power of the laser 400. The adjustment method is simple and convenient. Furthermore, during laser 400 operation, its power and other parameters can be fed back to the display screen 500 in real time. The operating parameters of the laser 400 are easily obtained by the operator, and the information displayed on the display screen 500 can accurately guide the adjustment of the laser 400, avoiding excessive power and enhancing safety.

[0042] The following embodiments illustrate the details of the controllable digital display laser therapy device handle of this application.

[0043] Please refer to Figures 1-4 In this embodiment, the controllable digital display laser therapy device handle optionally includes a housing 100, a controller 200, a circuit board 300, a laser 400, a display screen 500, a control 600, and a working tip 700.

[0044] The controller 200, circuit board 300, laser 400, display screen 500, adjustment control 600, and working tip 700 can all be mounted on the housing 100, and can be installed inside the housing 100. The working tip 700 can extend beyond the front end 101 of the housing 100 for convenient operation. The display screen 500 is mounted on the surface of the housing 100, allowing the operator to visually access information. Part of the adjustment control 600 can also be located outside the housing 100, facilitating manual adjustment of its position relative to the housing 100.

[0045] Optionally, the controller 200, laser 400, display screen 500, and adjustment control 600 can all be electrically connected to the circuit board 300. The controller 200 can be of various types; it can directly adopt the controller 200 used in existing laser therapy devices, and this embodiment does not impose a specific limitation. The laser 400, display screen 500, and circuit board 300 can all adopt existing technologies, and this embodiment does not impose a specific limitation on their models. The controller 200 can be directly integrated onto the circuit board 300, and the laser 400 can be fixed onto the circuit board 300. The controller 200 can adjust the operating state of the laser 400.

[0046] In addition, heat sink fins can be installed on the back of the circuit board 300 to improve heat dissipation performance.

[0047] Optionally, the housing 100 has a front end 101 and a rear end 102. The front end 101 of the housing 100 is provided with a mounting through hole 110, which allows the working tip 700 and the adjustment control 600 to extend out of the front end 101. An arc-shaped slide rail 120 is provided on the inner wall surface of the front end 101, and the arc-shaped slide rail 120 extends circumferentially in the mounting through hole 110. It should be understood that the arc-shaped slide rail 120 can be an annular slide rail, which can provide a stable and reliable guiding effect.

[0048] Please refer to Figures 3-4Furthermore, the arc-shaped slide 120 includes a connected variable-diameter feedback section 121 and a constant-diameter guide section 122. The variable-diameter feedback section 121 has a first inner wall 1211 and a second inner wall 1212 disposed opposite to each other in the axial direction of the mounting through hole 110. At least one of the first inner wall 1211 and the second inner wall 1212 is configured as an elastic wall. In this embodiment, both the first inner wall 1211 and the second inner wall 1212 are configured as elastic walls. Specifically, an elastomer can be disposed on the surface of the first inner wall 1211 and the second inner wall 1212. The elastomer can be rubber or silicone, etc., and the elastomer can be vulcanized and molded onto the first inner wall 1211 and the second inner wall 1212, resulting in a firm and reliable bond. At the same time, the distance between the first inner wall 1211 and the second inner wall 1212 gradually decreases in a first direction. The constant-diameter guide section 122 is connected to the variable-diameter feedback section 121, and the two are arranged sequentially in the circumferential direction of the housing 100. The constant-diameter guide section 122 and the variable-diameter feedback section 121 cooperate to form an arc-shaped slide 120 with an annular structure. The width of the constant-diameter guide section 122 is consistent in the axial direction of the mounting through hole 110. The width of the constant-diameter guide section 122 can be the same as the width of the smallest end of the variable-diameter feedback section 121, or it can be the same as the width of the largest end of the variable-diameter feedback section 121, etc., and can be processed as needed.

[0049] Furthermore, the arc-shaped slide 120 has an inner peripheral wall, which is connected to both the first inner wall 1211 and the second inner wall 1212, and a limit protrusion 130 is provided on the inner peripheral wall.

[0050] It should be understood that, in order to facilitate the processing of the housing 100 and the installation of other components inside the housing 100, the housing 100 can be configured as a split structure. For example, the housing 100 includes two half-shells that are snapped together, and the variable diameter feedback section 121 and the constant diameter guide section 122 can be distributed on the two half-shells.

[0051] In this embodiment, optionally, the control panel 600 includes a knob 610, a Hall effect sensor module, and an anti-slip sleeve 620. The knob 610 includes an integrated rotating cap 611 and an arc-shaped guide strip 612. The rotating cap 611 is a hollow structure, and the arc-shaped guide strip 612 is located on the outer peripheral surface of the rotating cap 611, through which the working tip 700 can pass. A limiting groove 613 is provided on the outer peripheral surface of the arc-shaped guide strip 612. The limiting groove 613 is an arc-shaped groove that extends circumferentially on the rotating cap 611. The limiting groove 613 has a first groove sidewall 6131 and a second groove sidewall 6132 disposed opposite to each other in its length direction. In a first direction, the first groove sidewall 6131 is located in front of the second groove sidewall 6132. The thickness of the arc-shaped guide strip 612 in the axial direction of the rotating cap 611 is not greater than the maximum width of the variable diameter feedback section 121, and is greater than the minimum width of the variable diameter feedback section. The arc-shaped guide strip 612 is rotatably engaged with both the variable diameter feedback section 121 and the constant diameter guide section 122.

[0052] During assembly, the rotating cap 611 passes through the assembly through hole 110, and the arc-shaped guide strip 612 is rotatably connected to both the variable diameter feedback section 121 and the equal diameter guide section 122. Furthermore, the limiting protrusion 130 is inserted into the limiting groove 613. Simultaneously, the arc-shaped guide strip 612 has a forward-facing end in the first direction, which can enter the variable diameter feedback section 121, and the arc-shaped guide strip 612 can simultaneously contact the first inner wall 1211, the second inner wall 1212, and the two inner walls of the equal diameter guide section 122 in the axial direction of the assembly through hole 110. As the arc-shaped guide bar 612 rotates relative to the outer casing 100 along the first direction, the distance between the first inner wall 1211 and the second inner wall 1212 gradually decreases, resulting in increasing pressure between the arc-shaped guide bar 612 and the first and second inner walls 1211. This leads to tighter contact between the arc-shaped guide bar 612 and the variable-diameter feedback section 121, meaning the resistance provided by the variable-diameter feedback section 121 increases. Consequently, the rotation of the knob 610 along the first direction can be correlated with a gradual increase in the power of the laser 400. When the operator increases the power of the laser 400, the feedback becomes increasingly noticeable, prompting the operator to appropriately increase the output power of the laser 400 and effectively reducing the probability of misoperation. Furthermore, when the knob 610 rotates along the first direction, the second groove sidewall 6132 contacts the limiting protrusion 130, thereby mechanically limiting the angle of rotation of the knob 610 along the first direction. Similarly, when the knob 610 is rotated in a second direction opposite to the first direction, the limiting protrusion 130 can contact the first groove sidewall 6131 to limit the angle of rotation of the knob 610 in the second direction. Through the cooperation of the first groove sidewall 6131, the second groove sidewall 6132 and the limiting protrusion 130, the rotation range of the knob 610 relative to the housing 100 can be limited, thereby determining the power adjustment range of the laser 400.

[0053] It should be understood that since the arc-shaped guide bar 612 can always be in contact with the equal-diameter guide section 122 when rotating, the stability of the knob 610 rotation can be ensured through the equal-diameter guide section 122.

[0054] It is worth noting that the anti-slip sleeve 620 can be made of rubber or silicone, etc. The anti-slip sleeve 620 can be set outside the rotating cap 611. Applying force to the anti-slip sleeve 620 drives the rotating cap 611, which is not easy to slip and saves time and effort.

[0055] Optionally, the Hall sensing module includes a Hall magnet 630 and a Hall effect sensor 640. The Hall magnet 630 is mounted on the rotating cap 611 of the knob 610 and is located on the end face of the rotating cap 611 that is inserted into the housing 100. The Hall magnet 630 and the rotation axis of the knob 610 are spaced apart. The Hall effect sensor 640 is mounted inside the housing 100 and is electrically connected to the circuit board 300. The Hall magnet 630 is located within the sensing area of ​​the Hall effect sensor 640, which is used to acquire the magnetic field information of the Hall magnet 630. During operation, by rotating the knob 610, the knob 610 causes the Hall magnet 630 to rotate relative to the Hall effect sensor 640. The Hall effect sensor 640 can sense changes in the magnetic field information. The controller 200 can receive the magnetic field information acquired by the Hall effect sensor 640, process the magnetic field information, and generate a corresponding control signal. The output power of the laser 400 is controlled by the control signal, thus achieving flexible adjustment of the output power of the laser 400.

[0056] It should be understood that, in some embodiments, in order to more accurately control the output power of the laser 400, multiple Hall effect sensors 640 can be set to simultaneously acquire the magnetic field information of the Hall magnet 630.

[0057] In other embodiments, the controllable digital display laser therapy device may further include a laser rangefinder connected to the housing 100 and electrically connected to the controller 200. The laser rangefinder acquires distance information between itself and the surface of the object being measured. As the depth of the working tip 700 into the tissue increases, the real-time distance information gradually decreases. The cutting depth can be obtained by the difference between the initial distance information and the real-time distance information. The initial distance information refers to the distance information between the laser rangefinder and the tissue surface when the working tip 700 is just in contact with the tissue.

[0058] Meanwhile, the controllable digital display laser therapy device may also include an alarm, which is electrically connected to the controller 200. When the total cutting depth or the cutting depth of a single operation exceeds a corresponding threshold, the controller 200 controls the alarm to sound an alarm and can directly cut off the power supply to stop the laser 400, thereby improving safety. Both the alarm and the laser rangefinder can adopt existing structures, which will not be described in detail in this embodiment.

[0059] It should be understood that the working tip 700 provided in this embodiment can be a laser treatment head, etc.

[0060] The controllable digital display laser therapy device provided in this embodiment has diverse functions and is convenient and reliable to operate.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
