[0007] The beneficial effect of the present invention is that when the illumination area of ​​the laser needs to be adjusted according to actual conditions, the illumination area of ​​the laser beam emitted by the laser generator can be adjusted by utilizing the adjustment unit, thereby providing convenience for users.

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the device body includes a controller body, an optical fiber box and a laser generator. The optical fiber box is assembled on the controller body and connected to the laser generator through an optical fiber.

[0010] The above technical solution provides a handheld laser generator, thereby making it convenient for the user to hold the laser generator to stop bleeding, disinfect or cut the soft tissue of the wound.

[0011] Furthermore, the laser generator is a cylindrical component, one end of the laser generator is a holding part, and the other end is a laser emitting part. The adjustment tube part is arranged on the laser emitting part and is used to adjust the irradiation area of ​​the laser beam.

[0012] The above technical solution divides the laser generator into a holding part and a laser emitting part, and utilizes an adjustment part arranged on the laser emitting part, thereby facilitating the user to adjust the irradiation area of ​​the laser beam.

[0013] Furthermore, the adjustment part includes an adjustment tube and an adjustment cover. The adjustment cover is a hollow truncated cone-shaped component and is assembled on the end of the laser emitting part. The adjustment tube is coaxially sleeved on the outside of the laser emitting part.

[0014] The above technical solution uses an adjustment cover of a truncated cone-shaped component and covers the end of the laser emitting part, thereby restricting the irradiation area of ​​the laser beam according to the opening area of ​​one end of the adjustment cover.

[0015] Furthermore, the adjusting tube fitting includes an adjusting tube, a limiting member and an adjusting member. The adjusting tube is coaxially sleeved on the outside of the laser emitting part and is slidably connected thereto. The limiting member is coaxially assembled on the inner wall of the bottom end of the adjusting tube.

[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. Example

[0036] like Figure 1-6 As shown, a laser therapeutic device with adjustable irradiation area includes a device body 1 and a laser generator 4. The device body 1 and the laser generator 4 are connected via an optical fiber. The laser generator 4 is provided with an adjustment part for adjusting the irradiation area of ​​the laser beam.

[0037] A bracket 3 for placing a laser generator 4 is provided on the side of the device body 1 .

[0038] The working principle is: when it is necessary to change the irradiation area of ​​the laser beam emitted by the laser generator 4 according to actual conditions, the user can adjust the irradiation area of ​​the laser beam according to actual conditions, thereby improving the convenience of using the device.

[0039] When the illumination area of ​​the laser needs to be adjusted according to actual conditions, the above technical solution can adjust the illumination area of ​​the laser beam emitted by the laser generator by utilizing the adjustment unit, thereby providing convenience for users.

[0040] Preferably, the device body 1 includes a controller body 101 , an optical fiber box 2 and a laser generator 4 . The optical fiber box 2 is mounted on the controller body 101 and connected to the laser generator 4 via an optical fiber.

[0041] The working principle is: the laser beam is irradiated through the laser generator 4 via the optical fiber, and the user holds the laser generator 4 to stop bleeding, disinfect or cut the patient.

[0042] The above technical solution provides a handheld laser generator, thereby facilitating the user to use the handheld laser generator to stop bleeding, disinfect or cut the soft tissue of the wound.

[0043] Preferably, the laser generator 4 is a cylindrical component, one end of the laser generator is a holding part, and the other end is a laser emitting part. The adjustment tube part is arranged on the laser emitting part for adjusting the irradiation area of ​​the laser beam.

[0044] The working principle is: by setting a cylindrical laser generator 4, it is convenient for users to use it for laser irradiation hemostasis or cutting, and it is also convenient for users to use it to improve the irradiation range.

[0045] The above technical solution divides the laser generator into a holding part and a laser emitting part, and utilizes an adjustment part arranged on the laser emitting part, thereby facilitating the user to adjust the irradiation area of ​​the laser beam.

[0046] Preferably, the adjustment part comprises an adjustment tube and an adjustment cover 403 . The adjustment cover 403 is a hollow truncated cone-shaped component and is assembled on the end of the laser emitting part. The adjustment tube is coaxially sleeved on the outside of the laser emitting part.

[0047] The working principle is: when the irradiation area of ​​the laser beam needs to be adjusted, the irradiation area of ​​the laser beam is changed by changing the area of ​​the opening at one end of the adjustment cover 403 .

[0048] The above technical solution uses an adjustment cover of a truncated cone-shaped component and covers the end of the laser emitting part, thereby restricting the irradiation area of ​​the laser beam according to the opening area of ​​one end of the adjustment cover.

[0049] Preferably, the adjusting tube fitting includes an adjusting tube 402, a limiter 405 and an adjusting member 404. The adjusting tube 402 is coaxially sleeved on the outside of the laser emitting part and slidably connected thereto. The limiter 405 is coaxially assembled on the inner wall of the bottom end of the adjusting tube 402. The adjusting member 404 is installed at the end of the laser emitting part and has a through hole in the middle thereof for the laser beam to pass through.

[0050] The working principle is: when the area of ​​the opening at one end of the adjustment cover needs to be changed, first move the adjustment tube 402, and use the movement of the adjustment tube 402 to drive the limit member 405 to move. During the movement, the limit member 405 is squeezed by the adjustment member 404, thereby adjusting and changing the area of ​​the opening at one end of the adjustment cover 403.

[0051] The above technical solution realizes the function of adjusting the irradiation area of ​​the laser beam conveniently and efficiently by providing an adjusting pipe fitting and using it in conjunction with a limiter to adjust the opening area of ​​the adjusting cover.

[0052] Preferably, the limiting member 405 includes a fixed ring 4051 and a movable block 4052. The fixed ring 4051 is provided with a plurality of strip grooves along its circumference. A sliding groove is provided at the bottom of the strip groove. A slider is slidably connected inside the sliding groove. The movable block 4052 is fixedly connected to the slider. A spring strip 4053 is provided between one end of the slider and the fixed ring 4051.

[0053] The working principle is as follows: when the limiter 405 moves with the adjusting tube 402, the limiter 405 is squeezed by the adjusting member 404, and its moving block 4052 moves toward the adjusting cover 403 and squeezes the adjusting cover 403 to shrink, thereby changing the area of ​​the opening at one end thereof, and further changing the irradiation area of ​​the laser beam.

[0054] The above technical solution sets a fixed ring and a moving block, and uses a moving adjustment tube to drive the limiter to move. When the limiter moves, the moving block inside it can squeeze the adjustment cover, and the area of ​​the opening at one end of the adjustment cover can be changed by moving the adjustment tube up and down.

[0055] Preferably, the adjusting member 404 includes a connecting ring 4041 and an extrusion block 4042. The connecting ring 4041 is fixedly assembled on the end of the laser emitting part through a connecting rod 4043. The extrusion block 4042 is circumferentially assembled on one side of the connecting ring 4041 close to the limiting member 405. One side of the extrusion block 4042 is a flat surface and the other side is an arc-shaped surface. A gap is formed between the moving block 4052 and the inner wall of the strip groove to cooperate with the adjusting member 404.

[0056] In which, when the spring strip 4053 is in a natural state, a gap is formed between the moving block 4052 and the inner wall of the strip groove, so that the extrusion block 4042 can enter the gap and squeeze the moving block 4052 to drive it to move.

[0057] The arc surface on one side of the extrusion block 4042 bends from bottom to top toward the through hole of the connecting ring 4041 .

[0058] The working principle is: when the limit member 405 moves, the extrusion block 4042 at the lower end of the adjustment member 404 moves with the limit member 405 and approaches the limit member 405. At this time, the lower end of the extrusion block 4042 enters the gap between the moving block 4052 and the fixed ring 4051. The arc surface on one side of the extrusion block 4042 is used to continuously squeeze the moving block during the upward movement of the moving block, so that it moves toward the adjustment cover 403.

[0059] The above technical solution is provided with an extrusion block and a connecting ring. When the movable tube drives the limit member to rise, the limit member moves to the adjusting member, and the adjusting member squeezes the limit member, thereby driving the limit member to move, and then the adjusting cover is squeezed by the limit member to change the area of ​​the opening at one end thereof.

[0060] Preferably, the adjustment cover 403 includes a mounting sleeve 4031, a plurality of arc-shaped blades 4032 and an elastic cloth 4033. The mounting sleeve 4031 is an annular component. The plurality of arc-shaped blades 4032 are distributed circumferentially along the mounting sleeve 4031 and are rotatably assembled on the mounting sleeve 4031 through a rotating member. The elastic cloth 4033 is assembled between two adjacent arc-shaped blades 4032.

[0061] The plurality of arc-shaped blades 4032 correspond to the plurality of moving blocks 4052 one by one.

[0062] The working principle is: when the moving block 4052 squeezes the adjustment cover 403, the moving block 4052 squeezes the arc blades 4032 corresponding thereto, so that the arc blades 4032 move closer to each other, thereby changing the area surrounded by the multiple arc blades 4032 to change the area of ​​the opening at one end of the entire adjustment cover 403.

[0063] The above technical solution provides a movable adjustment cover so that the area of ​​the opening at one end can be changed, thereby changing the irradiation area of ​​the laser beam.

[0064] Preferably, a strip-shaped opening is opened at one end of the arc-shaped blade 4032 , and the rotating member is located at the strip-shaped opening and connected to the arc-shaped blade 4032 .

[0065] The working principle is: when the arc-shaped blade 4032 is no longer squeezed, the rotating member can drive the arc-shaped blade 4032 to automatically deflect, so that the opening at one end of the entire adjustment cover 403 is expanded to facilitate the next adjustment.

[0066] The above technical solution changes the area of ​​the opening at one end of the adjustment cover by setting the arc blades. By changing the rotation angle of the arc blades, the area enclosed by the multiple arc blades can be changed when they rotate.

[0067] Preferably, the rotating member includes an axle seat 4034, a connecting shaft 4036 and a torsion spring 4035. The axle seat 4034 is fixedly assembled on the mounting sleeve 4031. The connecting shaft 4036 is placed horizontally and passes through the axle seat 4034. Its two ends are respectively rotatably assembled on the inner walls on both sides of the strip opening. The torsion spring 4035 is coaxially sleeved on the connecting shaft 4036. Its two ends are respectively connected and fixed to the axle seat 4034 and the arc-shaped blade 4032.

[0068] The working principle is as follows: when the rotating member drives the arc blade 4032 to rotate, the torsion spring 4035 inside it drives the arc blade 4032 to rotate around the connecting shaft 4036 as the axis due to its own elasticity, thereby achieving the deflection of the arc blade.

[0069] The above technical solution provides an elastic rotating member. When the moving tube moves downward, the rotating member drives the arc-shaped blades to deflect due to its own elastic force. After multiple arc-shaped blades are automatically deflected, the area of ​​the adjustment cover changes.

[0070] The above technical solution provides an elastic rotating member. When the moving tube moves downward, the rotating member drives the arc-shaped blades to deflect due to its own elastic force. After multiple arc-shaped blades are automatically deflected, the area of ​​the adjustment cover changes.
