Description

Technical Field

[0001] The present application relates to a semiconductor laser hair growth therapy device, and more particularly to a lifting mechanism and a cantilever assembly for a semiconductor laser hair growth therapy device, belonging to the technical field of medical devices. Background Art

[0002] Generally speaking, under normal scalp conditions, 15% of the hair is falling or has fallen. In other words, the hair follicles to which these hairs belong are in the regression and resting phases, and the remaining 85% of the healthy hair follicles are in the growth phase. The proportion of hair follicles in the growth phase of patients with hair loss will be greatly reduced, and a large number of hair follicles in the hair loss area are in the resting and regression phases. At the same time, DHT is a metabolite of male hormones. Hair follicles are sensitive to this substance, and hair loss patients are particularly serious.

[0003] Low-energy laser (LLLT), also known as soft laser or weak laser, must be single wavelength, parallel, in phase, and its energy must be between 0.001 and 0.1W. LLLT can reduce the concentration of male hormones in the sebaceous glands and the probability of DHT acting on the sebaceous glands, thereby reducing the decomposition and rupture of sebaceous gland cells, resulting in reduced oil secretion. LLLT can also activate the hair papilla of the hair follicle within a certain range. First, it can absorb more nutrients that are effective for hair growth from the dermal blood vessels; second, the activated hair papilla can cause the hair follicles to enter the growth phase from the catagen or resting phase, accelerating hair growth.

[0004] The mechanism of action of the semiconductor laser hair growth therapy device is to use weak laser and soft laser with a wavelength of 650-670nm and an energy of 0.005W. Since the hair papilla is the core part of the hair follicle that affects hair growth, it is rich in melanin. Melanin has a strong absorption of visible red light of 650-670nm. The hair papilla that absorbs the 650-670nm laser is activated.

[0005] At present, semiconductor laser hair growth therapy devices mainly include head-mounted and cart-mounted devices. The cart-mounted device has a cantilever structure and a lifting structure, so compared with the head-mounted device, there is no scalp pressure when using it, and the user experience is better. However, the cart-type semiconductor laser hair growth therapy devices in the related art, such as a mobile laser hair growth therapy helmet (CN219501869 U) and a low-illuminance laser hair growth device (CN 215653464 U), still have the following shortcomings:

[0006] When the cantilever structure adopts a multi-degree-of-freedom robotic arm, although it can adjust the angle of the treatment head to a large extent, the cost is relatively high; when the cantilever structure adopts a simple bracket, it is necessary to increase the number of joints for multi-angle adjustment, which will make the operation cumbersome and the precision difficult to control; in addition, the existing lifting structures are mostly manually adjusted and locked, and the stability and convenience are not high enough, and the interference of the lifting movement on the signal line of the treatment head is not taken into account, affecting the continuity of signal transmission.

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] In a related technology, a mobile laser hair growth treatment helmet (CN 219501869 U) has a cantilever structure corresponding to a multi-jointed mechanical arm, which can drive the laser hair growth treatment helmet to rise and fall and rotate within a certain range and hover at any position. However, it is not only cumbersome to operate and difficult to control the accuracy, but also has the disadvantage of being too costly when the mechanical arm is directly replaced by a high-precision robot arm. Its lifting structure corresponds to a telescopic rod with a locking mechanism, which is manually adjusted and locked, and the stability and convenience are not high enough. It also fails to take into account the interference of the lifting movement on the signal line of the treatment head, affecting the continuity of signal transmission.

[0056] In another related technology, a low-illuminance laser hair growth device (CN 215653464 U), the cantilever structure corresponds to the support arm, and the angle of the helmet shell is adjusted by the relative rotation between the swing rod and the support arm alone, which cannot achieve a maximum and multi-dimensional angle adjustment effect. Its lifting structure corresponds to the relative extension and contraction of the sleeve and the top rod, and the position is locked by the insertion rod, which is also manually adjusted and locked. The stability and convenience are not high enough, and the interference of the lifting movement on the signal line of the treatment head is not taken into account, affecting the continuity of signal transmission.

[0057] First embodiment

[0058] In view of this, the first embodiment of the present application provides a lifting mechanism 100 for a semiconductor laser hair growth therapy device 300, which can achieve a larger height adjustment of the treatment head to meet the needs of patients of different heights, and has higher flexibility, more convenient operation, and higher stability. At the same time, it can achieve better protection of the signal line of the treatment head and better transmission quality.

[0059] Reference Figures 1 to 7 , Figures 15 to 17 As shown, the lifting mechanism 100 of the first embodiment includes a lifting column 110, a keel bracket 120, an electric push rod 130 and a saddle-shaped slider module 140; the lifting column 110 is longitudinally arranged on the keel bracket 120; the keel bracket 120 is provided with a pair of lifting guide rails 122 parallel to the lifting column 110; the electric push rod 130 is fixedly connected to the keel bracket 120 and is drivingly connected to the lifting column 110; a plurality of saddle-shaped slider modules 140 are arranged at intervals along the axial direction of the lifting column 110, and each saddle-shaped slider module 140 is fixedly connected to the lifting column 110 and is slidably connected to the lifting guide rail 122.

[0060] In the first embodiment, the lifting mechanism 100 is mainly composed of a keel bracket 120, a lifting column 110, an electric push rod 130 and two saddle-shaped slider modules 140. The overall shape of the two saddle-shaped slider modules 140 combined with the lifting column is similar to a stable frame structure. The lifting column 110 is used as a reciprocating motion component, and the electric push rod 130 is used as a power source to drive the reciprocating motion. The user only needs to operate the extension and retraction of the electric push rod 130 to meet the lifting requirements, which is also conducive to achieving precise control; at the same time, with the help of two saddle-shaped slider modules 140 fixedly connected to the lifting column 110, a pair of lifting guide rails 122 slidably installed on the keel bracket 120 are improved. The stability and straightness of the lifting action are improved.

[0061] In a possible implementation of the first embodiment, the saddle-shaped slider module 140 includes a saddle-shaped connector 141 and two lifting sliders 142 respectively connected to a pair of lifting guide rails 122. The middle part of the saddle-shaped connector 141 is clamped and fixedly connected to the lifting column 110, and the two lifting sliders 142 are respectively fixedly connected to the two sides of the saddle-shaped connector 141.

[0062] During assembly, the connection between the saddle-shaped connector 141 and the lifting column 110 is in a semi-enclosed form, which can improve the firmness of the connection and strengthen the supporting force to achieve the purpose of maintaining positioning; based on the shape of the saddle-shaped connector 141, the guide rail slider assemblies can be symmetrically arranged on both sides of the lifting column 110, so as to better enable the lifting column 110 to move up and down smoothly in the center position, reducing the shaking and wear of the lifting mechanism 100.

[0063] In a possible implementation of the first embodiment, the lifting column 110 includes a column body 111 and a first adapter portion 1111 formed at one end of the column body 111, and the lifting column 110 is axially connected to the electric push rod 130 through the first adapter portion 1111. The lifting column 110 can be axially connected to the electric push rod 130 directly through its first adapter portion 1111 without an adapter, using a fastener or connector such as a pin.

[0064] In a possible implementation of the first embodiment, referring to Fig.17 The overall shape of the saddle-shaped connector 141 is an "I" shape; the column 111 is provided with a clamping shaft section 1112 that fits the inner cavity of the "I" shape.

[0065] In specific implementation, the clamping shaft segment 1112 is designed with a cross-sectional size smaller than the cross-sectional size of other parts of the column 111. The clamping shaft segment 1112 is adapted to the inner surface of the saddle-shaped connector 141 in appearance. When it is arranged at the end, it can also be used as the first adapter 1111 that is connected to the lifting column. More specifically, the lifting column is assembled inside the clamping shaft segment 1112, and the saddle-shaped connector 141 is assembled outside the clamping shaft segment 1112.

[0066] In a possible implementation of the first embodiment, the keel bracket 120 includes a keel plate 121 and a support plate 1211 integrally and vertically connected to the bottom of the keel plate 121, and the support plate 1211 is used to install the electric push rod 130. Specifically, a placement hole for the electric push rod 130 can be opened on the keel plate 121 to meet the positioning requirement that the push rod of the electric push rod 130 can be aligned with the lifting column 110 on which the saddle-shaped slider module 140 is installed.

[0067] In a possible implementation of the first embodiment, the lifting mechanism 100 further includes:

[0068] A tank chain 150, one end of which is fixedly connected to the keel bracket 120, and the other end of which is connected to the saddle-shaped slider module 140 and moves therewith;

[0069] The lifting column 110 is provided with a hollow cavity for the signal line of the treatment head of the semiconductor laser hair growth treatment device 300 to pass through, and the line outlet of the hollow cavity is connected to the tank chain 150.

[0070] In specific implementation, the signal line of the treatment head passes along the inner cavity of the tank chain 150150, and then runs along the hollow cavity of the lifting column 110. More specifically, the outlet is the opening on the bottom side of the lifting column 110110. The advantages of this design are that the signal line of the treatment head is completely hidden inside the tank chain 150 and the lifting column 110, and the product appearance is more beautiful; secondly, the transmission of wired signal data can be synchronized with the movement of the lifting column 110 without pulling and the signal is not interrupted.

[0071] Second embodiment

[0072] In view of this, the second embodiment of the present application provides another lifting mechanism 100 for a semiconductor laser hair growth therapy device 300, which can also achieve a larger height adjustment of the treatment head 320 to meet the needs of patients of different heights, and has higher flexibility, more convenient operation, and higher stability. At the same time, it can achieve better protection of the signal line of the treatment head and better transmission quality.

[0073] Reference Figures 8 to 14 , Figures 15 to 17 As shown, the lifting mechanism 100 of the second embodiment is mainly composed of a keel bracket 120, two lifting columns 110, two electric push rods 130 and four saddle-shaped slider modules 140. One lifting column 110, one electric push rod 130 and two saddle-shaped slider modules 140 constitute a set of lifting units, and two sets of such lifting units are arranged in parallel on one keel bracket 120. Other technical features are the same as those of the first embodiment, and can achieve the same technical effects, which will not be repeated here.

[0074] Third embodiment

[0075] In view of this, the third embodiment of the present application also provides a cantilever assembly 200 for a semiconductor laser hair growth therapy device 300, which can achieve a greater degree of multi-dimensional posture adjustment of the treatment head 320 to meet the needs of patients in different positions, and can simplify the structure and reduce costs.

[0076] Reference Fig.18 and Fig.19 As shown, the cantilever assembly 200 of the third embodiment includes a crossbeam support arm 210, a treatment head support arm 220 and the lifting mechanism 100 of the first embodiment, wherein the semiconductor laser hair growth treatment device 300 includes a main unit 310 and a treatment head 320, and the lifting column 110 and the keel support 120 of the lifting mechanism 100 of the first embodiment are respectively connected to the treatment head 320 and the main unit 310. The lifting mechanism 100 is arranged inside the main unit 310; the lifting column 110 of the lifting mechanism 100 extends upward from the main unit 310, and is connected to the treatment head 320 through the crossbeam support arm 210 and the treatment head support arm 220 in turn, and the two ends of the treatment head support arm 220 are provided with a damping shaft member 221 and a damping shaft assembly 222 for respectively realizing the horizontal rotation action and the vertical flip action of the treatment head 320.

[0077] In specific implementation, the damping shaft member 221 and the damping shaft assembly 222 can both adopt disc-shaped damping shafts. The damping shaft member 221 is a horizontally placed disc-shaped damping shaft, and the axis of the disc-shaped damping shaft is arranged in line with the axis of the treatment head support arm 220; the damping shaft assembly 222 is two vertically placed disc-shaped damping shafts, and the axes of the disc-shaped damping shafts are arranged perpendicular to the axis of the treatment head support arm 220. The treatment head support arm 220+damping shaft member 221+damping shaft assembly 222 form a composite joint of the treatment head 320, which integrates horizontal rotation and / or vertical flipping movements, and maximizes the configuration of various posture angles of the treatment head 320. Therefore, the crossbeam support arm 210 of the third embodiment is the main structure of the cantilever assembly 200, and the performance requirements can be met without setting more supports and joints, which greatly reduces the cost.

[0078] In a possible implementation of the third embodiment, the horizontal rotation action is configured as the treatment head 320 horizontally rotating 90° to the left and right, and is achieved by the damping shaft member 221 cooperating with the first limiting structure provided at the connection between the treatment head support arm 220 and the crossbeam support arm 210;

[0079] The vertical flipping action is configured as the treatment head 320 raising and lowering the head by 30° each, and is achieved by the damping shaft assembly 222 cooperating with the second limiting structure provided at the connection between the crossbeam support arm 210 and the treatment head.

[0080] The first limiting structure is used to constrain the rotation angle to 90° and the direction to the left and right. The second limiting structure is used to constrain the rotation angle to 30° and the direction to the upward and downward. The structures of the first limiting structure and the second limiting structure are not limited and can be matched blocks or plug-ins.

[0081] In a possible implementation of the third embodiment, the lifting column 110 includes a column 111, one end of the lifting column 110 is axially connected to the electric push rod 130, and the other end thereof is connected to the beam support arm 210 through the support arm transfer fixture 230 and can make the beam support arm 210 rotate horizontally around the lifting column 110; the one end and the other end here correspond to the above-mentioned first transfer portion 1111 and the second transfer portion 1113 of the lifting column, respectively. One end of the support arm transfer fixture 230 is fixedly connected to the beam support arm 210, and the other end thereof is rotatably connected to the lifting column 110.

[0082] In actual use, the arm adapter fixture 230 is also equivalent to a composite joint, which not only satisfies the vertical connection between the beam arm 210 and the lifting column 110, but also satisfies the relative horizontal rotation of the two, so as to achieve the purpose of moving the treatment head 320 in a large range of space.

[0083] In a possible implementation of the third embodiment, the keel bracket 120 includes a keel plate 121, a support plate 1211 for mounting the electric push rod 130 is provided at the bottom of one side of the keel plate 121, and a first reinforcement plate 1212 and a second reinforcement plate 1213 for connecting to the main unit 310 are respectively fixed at the top and the middle of the other side of the keel plate 121.

[0084] The support plate 1211 , the first reinforcement plate 1212 and the second reinforcement plate 1213 are distributed at different heights on both sides of the keel plate 121 and are combined into a reinforcing rib system, thereby ensuring the structural rationality of the keel bracket 120 .

[0085] Furthermore, the crossbeam support arm 210 is also provided with a wiring lumen, and the treatment head signal line is routed from the treatment head 320 to the crossbeam support arm 210, the lifting column 110 and the tank chain 150 in sequence, and finally connected to the main control, thereby achieving full protection for the treatment head signal line.

[0086] Fourth embodiment

[0087] In view of this, the fourth embodiment of the present application provides another cantilever assembly 200 for a semiconductor laser hair growth therapy device 300, which can also achieve a greater degree of multi-dimensional posture adjustment of the treatment head 320 to meet the needs of patients in different positions, and can simplify the structure and reduce costs.

[0088] Reference Fig. 20 As shown, the cantilever assembly 200 of the fourth embodiment includes a beam support arm 210, a treatment head support arm 220 and the lifting mechanism 100 of the second embodiment, wherein the semiconductor laser hair growth treatment device 300 includes two mainframes 310 and two treatment heads 320, and one mainframe 310 and one treatment head 320 are connected to the two ends of a lifting unit of the lifting mechanism 100 of the second embodiment. Other technical features are the same as those of the third embodiment, and can achieve the same technical effects, which will not be repeated here.
