Technical Field

[0001] The utility model relates to the technical field of laser therapy, and particularly relates to a spot size adjusting mechanism for a laser therapy head handle. Background Technique

[0002] Clinically, laser is often used for removing freckles, moles, and hair removal. Laser therapy has become a beauty treatment method. Laser freckle and mole removal uses a method with less skin trauma to fundamentally remove freckles and moles, so it is safer and has better effects.

[0003] Laser therapy is widely used in practice. During operation, most staff directly hold the laser therapy handle and use the therapy handle to perform fixed-point treatment on the positions of patients that need treatment. The spot size irradiated by common laser therapy handles is fixed. In order to obtain different spot sizes, usually the method of replacing the therapy head is used to change the spot size. This method is more inconvenient, and the storage and maintenance of multiple therapy heads will also be an additional burden. Therefore, a spot size adjusting mechanism for a laser therapy head handle is proposed to solve the above-mentioned problems. Content of the Utility Model

[0004] Based on the above description, the utility model provides a spot size adjusting mechanism for a laser therapy head handle to solve the problem that the existing laser therapy head handle needs to replace the therapy head when adjusting the spot size.

[0033] Please refer to Figures 1-4 and Figure 6 , the spot size adjusting mechanism of the laser treatment head handle, comprising:

[0034] The handle body, which includes a connecting head 1, an optical fiber connecting piece 2, an intermediate piece 3, a connecting sleeve 4, a treatment head 8, a clamping piece 9, a first sealing ring 10 and a clamping position block 11, wherein,

[0035] The connecting head 1 is connected to the clamping position block 11 by screws. An optical fiber connecting piece 2 and an intermediate piece 3 are arranged between the connecting head 1 and the clamping position block 11. The optical fiber connecting piece 2 and the intermediate piece 3 are in communication with each other. The clamping position block 11 includes a block body 111, and an annular groove 112 is arranged on the outer part of the block body 111;

[0036] The connecting sleeve 4 and the clamping piece 9 are both arranged on the outer part of the clamping position block 11 and are clamped with each other. A rectangular opening 44 is arranged on the outer surface of the connecting sleeve 4. The connecting sleeve 4 includes a hollow sleeve 41. One end of the hollow sleeve 41 is provided with a sleeve body 42. A blind hole 43 and a rectangular opening 44 are arranged on the outer surface of the sleeve body 42. A clamping groove 45 is arranged on the inner surface of the hollow sleeve 41. A second sealing ring 12 is arranged inside the clamping groove 45. The second sealing ring 12 extends into the annular groove 112. A spring 13 is arranged inside the blind hole 43. A ball 14 is arranged at one end of the spring 13. The ball 14 is in contact with the inner surface of the transmission part 5;

[0037] The treatment head 8 is clamped at one end of the connecting sleeve 4. The treatment head 8 includes a concave lens that cooperates with the moving lens 7, so that the light refracted by the moving lens 7 remains horizontal when irradiated. Since the treatment head 8 belongs to the prior art and the internal structure of the treatment head 8 is not the protection subject of this patent, the specific structure of the treatment head is not described in detail here;

[0038] Based on the above, the optical fiber connector 2 and the intermediate member 3 cooperate with each other, enabling the optical fiber to be connected to the handle, and the light emitted from the optical fiber can pass through the handle and be emitted from the treatment head 8. The setting of the blind hole 43 fixes the positions of the spring 13 and the ball 14, so that when the transmission member 5 rotates, it contacts the ball 14 to ensure smooth rotation of the transmission member 5. The setting of the rectangular opening 44 restricts the movement direction of the movable lens 7, allowing the movable lens 7 to move only along the direction of the rectangular opening 44.

[0039] As Figure 2 、 Figure 3 、 Figure 8 and Figure 9 shown, the rotating sleeve 6 is arranged between the connecting sleeve 4 and the clamping member 9 and sleeved outside the connecting sleeve 4. The rotating sleeve 6 includes a sleeve block 61 and a limiting strip 62. The transmission member 5 is arranged inside the sleeve block 61, and the limiting strip 62 extends into the transmission groove 53.

[0040] Based on the above, the setting of the limiting strip 62 enables the transmission member 5 to rotate together with the rotating sleeve 6.

[0041] As Figure 2 、 Figure 3 、 Figure 7 and Figure 8 shown, the transmission member 5 is arranged between the connecting sleeve 4 and the rotating sleeve 6 and includes a spiral opening 52. The transmission member 5 includes a transmission sleeve 51. The outer surface of the transmission sleeve 51 is provided with a spiral opening 52 and a transmission groove 53, and the transmission grooves 53 are annularly and equally distributed.

[0042] The movable lens 7 is arranged inside the connecting sleeve 4 and includes a connecting screw 72. Among them,

[0043] The connecting screw 72 passes through the rectangular opening 44 and extends into the spiral opening 52. The movable lens 7 includes a lens body 71 and a connecting screw 72. The outer surface of the lens body 71 is provided with a connecting screw 72, and the connecting screw 72 is threadedly connected to the lens body 71.

[0044] Based on the above, the setting of the transmission groove 53 enables the rotating sleeve 6 to drive the transmission member 5 to rotate together when rotating. The setting of the spiral opening 52 enables the movable lens 7 to push the connecting screw 72 to move along the direction of the rectangular opening 44 when the transmission member 5 rotates, thus achieving the effect of changing the position of the movable lens 7.

[0045] In actual use of this embodiment, the rotation of the rotating sleeve 6 drives the transmission member 5 to rotate. When the transmission member 5 rotates, the spiral opening 52 rotates together. At this time, the connecting screw 72 moves along the direction of the rectangular opening 44 under the push of the side wall of the screw opening 52, thereby achieving the effect of adjusting the position of the moving lens 7. By changing the position of the lens, the position of the light refracted by the lens is changed, that is, the position of the refracted focus is changed from the position of the treatment head 8. With the distance between the patient and the treatment head 8 remaining unchanged, the size of the irradiated light spot is changed;

[0046] In this treatment handle, through the cooperation among the connecting sleeve 4, the transmission sleeve 5, the rotating sleeve 6 and the moving lens 7, the position of the moving lens 7 can be moved, thereby changing the size of the light spot. Compared with the method of changing the light spot size by replacing the treatment head 8, this method is more convenient and faster.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
