[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1-10 As shown, an expandable laser therapy instrument handle in this embodiment can firstly control the change of the spot area through a rotation adjustment method to change the operation mode of the expandable laser therapy instrument handle. To complete this design, the expandable laser therapy instrument handle mainly includes an outer shell 1, an inner mounting seat 2 and an expandable laser component 3, wherein the inner mounting seat 2 is arranged in the outer shell 1, and the inner mounting seat 2 has two end faces, namely a head end face 21 and a tail end face 22, and the expandable laser component 3 is detachably connected to the side of the head end face 21 of the inner mounting seat 2.

[0024] The extended laser component 3 includes a guide sleeve 31 which is detachably connected to the inner side of the inner mounting seat 2. An adjusting sleeve 32 is coaxially rotatably connected to the outer side of the guide sleeve 31. The adjusting sleeve 32 is also coaxially rotatably connected to the inner mounting seat 2. In addition, a spiral lifting hole 321 is provided on the inner wall of the adjusting sleeve 32. Two groups of waist holes 311 are provided on the outer side of the guide sleeve 31 along the axial direction. A transmission rod 33 is slidably connected in each group of waist holes 311. One end of the two groups of transmission rods 33 is slidably connected to the spiral lifting hole 321. A light source 34 is slidably connected to the inner side of the guide sleeve 31. The end of the transmission rod 33 away from the spiral lifting hole 321 is threadedly connected to the light source 34. In addition, a concave lens 35 is detachably connected to the side of the guide sleeve 31 away from the tail end face 22.

[0025] When designed in this way, the position of the concave lens 35 is fixed, but when the sleeve 32 is rotated to adjust the transmission rod 33, the transmission rod 33 and the light source 34 can be moved closer to or away from the concave lens 35 under the limiting effect of the waist hole 311 on the transmission rod 33, thereby controlling the change in the spot area and changing the operating mode of the expandable laser therapy device handle.

[0026] The concave lens 35 is detachably connected to the side of the guide sleeve 31 away from the tail end face 22 as described below. The side of the guide sleeve 31 away from the tail end face 22 is provided with an internal thread and an external thread, and a trumpet-shaped flare 37 is threadedly connected to the internal thread. An inner step adjacent to the internal thread is provided in the guide sleeve 31, and a placement rack is placed on the inner step. The concave lens 35 is pressed by the flare 37 and placed on the inner side of the placement rack.

[0027] The handle of the expandable laser therapy instrument also includes a replaceable light-transmitting component 4, which is detachably connected to the guide sleeve 31 through the external thread of the guide sleeve 31. Specifically, the replaceable light-transmitting component 4 includes a light-transmitting mirror 41, a shell head 42 and a head cover 43, wherein the shell head 42 is threadedly connected to the guide sleeve 31 through the external thread, and an adapting thread is provided on the outside of the shell head 42. The head cover 43 is threadedly connected to the shell head 42 through the adapting thread. Furthermore, a light-transmitting hole is provided at the end of the head cover 43 away from the shell head 42, and the aperture of the light-transmitting hole is smaller than the outer diameter of the light-transmitting mirror 41. The light-transmitting mirror 41 is arranged between the shell head 42 and the head cover 43.

[0028] In a certain embodiment, the light-transmitting mirror 41 is placed on the end of the shell head 42 and is pressed and limited by the inner top wall of the head cover 43. At this time, the light-transmitting mirror 41 is, for example, in the shape of an oblate cylinder. If it can meet the needs of light transmission and treatment, it can be understood that in other implementations, the light-transmitting mirror 41 can also be in the shape of a rectangle or the like.

[0029] In a further embodiment, a limit bracket 6 is provided on the outer side of the shell head 42 so as to be liftable, and a universal pulley 7 is installed at the bottom of the limit bracket 6 .

[0030] For example, a semicircular hoop 8 is integrally connected to the outer side of the shell head 42. There are four groups of semicircular hoops 8, which are symmetrically distributed in pairs. The two groups of semicircular hoops 8 on the same side are used to clamp the corresponding limit bracket 6. Bolts are used between the two groups of semicircular hoops 8 to control whether the limit bracket 6 is clamped, thereby realizing the clamping control of the limit bracket 6.

[0031] When designed in this way, since the limiting bracket 6 and the universal pulley 7 can be extended and retracted up and down, the vertical distance between the light-transmitting mirror 41 and the body surface can be controlled to achieve flexible application.

[0032] In another embodiment, see Figure 8 , which is a schematic diagram of the structure when the light transmitting mirror 41 is spherical and the diameter of the light transmitting mirror 41 is larger than the diameter of the shell 1 in an embodiment of the present invention. The light transmitting mirror 41 is rollably arranged on the inner side of the shell head 42. The light transmitting mirror 41 is spherical, and the inner walls of the shell head 42 and the head cover 43 are arc-shaped. After the shell head 42 and the head cover 43 are assembled, a receiving cavity is formed. The light transmitting mirror 41 is rollably arranged in the receiving cavity. At this time, the side of the light transmitting mirror 41 away from the inner mounting seat 2 is exposed to ensure that the light transmitting mirror 41 can directly contact the surface of the human body.

[0033] When designed in this way, the operator can slide and press the patient's body surface through the light-transmitting mirror 41 to achieve massage and irradiation at the same time.

[0034] It is understandable that when the light-transmitting mirror 41 is spherical, its size can be large or small. Figure 9 This is a structural diagram of an embodiment of the present invention in which the light transmitting mirror 41 is spherical and the diameter of the light transmitting mirror 41 is smaller than the diameter of the shell 1. When the light transmitting mirror 41 is spherical and of a smaller size, that is, the diameter of the light transmitting mirror 41 is smaller than the diameter of the shell 1, the operator can perform fixed-point pressing on the patient's acupuncture points through the light transmitting mirror 41 and achieve massage and irradiation at the same time.

[0035] It should be noted that a positioning section 11 is provided at an inner wall of the shell 1, and a groove is provided on the outer side of the inner mounting seat 2, and a positioning strip 25 is provided in this groove. In this way, when the inner mounting seat 2 is placed in the shell 1, it is possible to know whether the inner mounting seat 2 is installed in place through the positioning section 11 and the positioning strip 25. In addition, a control button 26 is detachably connected to the outer side of the inner mounting seat 2, and the control button 26 is fixedly connected to the inner mounting seat 2 by a bolt. In addition, a limiting hole adjacent to the positioning strip 25 is provided on the outer side of the inner mounting seat 2, and the cross-section of the limiting hole is convex. A limiting member 27 is installed on the inner side of the limiting hole, and a hexagonal groove is provided on the limiting member 27. A hexagonal pin is provided at this hexagonal groove, and the head of the hexagonal pin is in contact with the positioning section 11, and an annular groove 312 is provided on the outer side of the guide sleeve 31, and one side of the limiting member 27 is located in the annular groove 312, thereby realizing the limitation of the guide sleeve 31.

[0036] As for the further explanation of the positions of the guide sleeve 31 and the adjusting rotary sleeve 32, the cross-sections of the guide sleeve 31 and the adjusting rotary sleeve 32 are both stepped shaft-shaped, and a docking hole 1 is provided on one side of the head end face 21 of the inner mounting seat 2, and a docking hole 2 connected to the docking hole is provided in the inner mounting seat 2, and the docking hole 1 is directly connected to the docking hole 2, and the diameter of the docking hole 1 is larger than the diameter of the docking hole 1, forming step 1 23 and step 2 24, and the side of the guide sleeve 31 close to the tail end face 22 is located at step 24, and the side of the adjusting rotary sleeve 32 close to the tail end face 22 is located at step 1 23. In addition, the inner wall of the outer shell 1 wraps the adjusting rotary sleeve 32 and reserves space for toggling the adjusting rotary sleeve 32.

[0037] In addition, a plurality of recessed grooves are formed on the outer side of the adjusting sleeve 32 to provide a space for turning the adjusting sleeve so that the operator can easily turn the adjusting sleeve.

[0038] When designed in this way, multiple sealing points are formed between the inner mounting seat 2, the guide sleeve 31 and the adjusting rotary sleeve 32, ensuring that the handle of the expandable laser therapy device has good sealing performance.

[0039] It should also be noted that in order to ensure that the light source 34 has good stability and ensure that the axis of the light source is not easily offset due to movement or vibration of the equipment, a fixing seat 36 is provided on the side of the light source 34 close to the tail end face 22. This fixing seat 36 is located on the inner side of the inner mounting seat 2, the guide sleeve 31 and the outer shell 1. Specifically, a threaded hole is provided on the side of the fixing seat 36 close to the light source 34, and a threaded part is provided on the side of the light source 34 close to the fixing seat 36. This threaded part is threadedly connected to the fixing seat 36 through the threaded hole. In addition, the expandable laser therapy instrument handle also includes a tail fixing component 5, which is detachably connected to the side of the tail end face 22 of the inner mounting seat 2.

[0040] Specifically, first, a threaded section is provided on one side of the tail end face 22 of the inner mounting seat 2, and a positioning step adjacent to the threaded section is provided in the inner mounting seat 2. The tail fixing component 5 includes an outer protective sleeve 51 provided at the positioning step, and a tail sealing sleeve 52 threadedly connected to the threaded section is provided on the outer side of the outer protective sleeve 51. The outer protective sleeve 51 and the tail sealing sleeve 52 are extended from the outer shell 1 away from the side of the inner mounting seat 2, and a positioning wing 521 is integrally connected to the outer side of the tail sealing sleeve 52, and the positioning wing 521 is attached to the tail of the outer shell 1. In addition, one end of the fixing seat 36 passes through the outer protective sleeve 51, and the outer protective sleeve 51 is slidably connected to the fixing seat 36. The outer protective sleeve 51 and the tail sealing sleeve 52 also play a sealing role, and the outer protective sleeve 51 can also keep the fixing seat 36 stable, ensuring that the fixing seat 36 does not deviate, that is, the light source 34 has good stability, ensuring that it is not easy for the light source axis to deviate due to equipment movement or vibration.
