Description

Technical Field

[0001] This utility model relates to the field of laser therapy equipment technology, and in particular to a single-spot handpiece and a laser therapy instrument. Background Technology

[0002] The application of laser fiber in the medical field demonstrates broad prospects and enormous development potential. With its significant advantages such as high precision, low invasiveness, and flexibility, laser fiber has become an important tool in many medical fields, including surgical treatment, oncology treatment, cosmetic surgery, ophthalmic surgery, and dental treatment. In surgical treatment, laser fiber enables precise tissue cutting, coagulation hemostasis, and ablation, significantly improving the accuracy and safety of surgery while reducing surgical trauma and patient recovery time. In oncology treatment, laser fiber, through photodynamic therapy or direct laser irradiation, can precisely destroy tumor tissue, providing patients with new, safer, and more effective treatment options. Furthermore, laser fiber also plays an important role in cosmetic surgery, ophthalmic surgery, and dental treatment, bringing patients safer and more effective treatment options and greatly improving medical outcomes and the patient's recovery experience.

[0003] Most existing single-spot handpieces can only achieve a fixed spot diameter, while treatment operations often require the preparation of multiple single-spot handpieces with different spot diameters. This demand leads to two problems: firstly, the manufacturing end (i.e., single-spot handpiece manufacturers) needs to design and manufacture single-spot handpieces of different specifications according to the needs of different spot diameters, which makes the manufacturing cost of single-spot handpieces high; secondly, the application end (e.g., hospitals) needs to manage multiple single-spot handpieces, which makes management more difficult.

[0004] Based on the above, there is an urgent need for a single-spot handpiece and laser therapy device to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a single-spot handpiece and laser therapy device that can reduce manufacturing costs on the production side and reduce management difficulties on the application side.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Single-spot handheld devices, including:

[0008] Handle, the handle having a first inner cavity through which the laser passes;

[0009] The lens barrel is detachably mounted to the handle, and a second inner cavity is formed inside the lens barrel. The first inner cavity and the second inner cavity are connected to allow the laser to pass through, and the inner wall of the second inner cavity is provided with an internal thread structure.

[0014] Preferably, the single-spot handpiece further includes a second lens, a third positioning member, and a fourth positioning member.

The single-spot handpiece also includes a contact element, one end of which has an abutment portion for abutting to stabilize the single-spot handpiece. The contact element is detachably mounted on the exiting end.

[0016] Preferably, the other end of the contact element has an annular connecting portion, the outer periphery of which is provided with the external thread structure, and the internal thread structure extends from the exit end into the lens barrel.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] The following is based on the appendix Figure 1 To be continued Figure 4 This invention introduces the single-spot handpiece and laser therapy device provided by this utility model.

[0042] like Figure 1 , Figure 2 As shown, in this embodiment, the single-spot handpiece mainly comprises a handle 1, a lens barrel 2, a first positioning element 3, a second positioning element 4, and a first lens 5. Both the handle 1 and the lens barrel 2 have a hollow structure; the handle 1 has a first inner cavity, and the lens barrel 2 has a second inner cavity. The handle 1 and the lens barrel 2 are detachably connected, thereby connecting the first and second inner cavities. The laser can pass through the first and second inner cavities sequentially and be output from the end of the lens barrel 2 to perform the treatment operation.

[0043] Reference Figure 2 As shown, in this embodiment, the inner wall of the second inner cavity is provided with an internal thread structure, and the outer periphery of the first positioning member 3 and the second positioning member 4 are both provided with an external thread structure. The internal thread structure and the external thread structure can mesh and connect, allowing the first positioning member 3 and the second positioning member 4 to be installed in the second inner cavity, and their positions can be changed. The first lens 5 is fixed between the first positioning member 3 and the second positioning member 4 by clamping and fixing, thereby fixing the first lens 5 to the lens barrel 2, and allowing the installation position between the first lens 5 and the lens barrel 2 to be changed. In this embodiment, the first lens 5 includes a convex lens (not shown in the figure) and a mounting ring 51, with the convex lens fixedly installed inside the mounting ring 51. Both the first positioning member 3 and the second positioning member 4 are pressure rings, which can clamp and fix the mounting ring 51 and reduce the obstruction of the laser.

[0044] Reference Figure 3 As shown, when the installation positions of the first positioning member 3, the second positioning member 4, and the first lens 5 are adjusted so that they are far away from the handle 1 (at which point the distance L between the first lens 5 and the light spot forming plane changes), the light spot output by the single-spot handpiece exhibits a phenomenon of reduced area and increased energy density. Conversely, when the installation positions of the first positioning member 3, the second positioning member 4, and the first lens 5 are adjusted so that they are close to the handle 1, the light spot output by the single-spot handpiece exhibits a phenomenon of increased area and decreased energy density.

[0045] Therefore, by rationally selecting the installation positions of the first positioning component 3, the second positioning component 4, and the first lens 5, the output phenomenon can be changed to meet different treatment needs without adjusting the structure of each component. This allows the production end to manufacture single-spot handpieces with different output phenomena using the same parts, greatly reducing the structural cost of the single-spot handpiece. Furthermore, it allows the application end to obtain a matching single-spot handpiece according to specific treatment needs and to flexibly adjust it according to the changed treatment needs. This significantly reduces the specification, quantity, and management requirements of the single-spot handpiece, which is conducive to reducing the procurement and management costs of the single-spot handpiece.

[0046] For example, in this embodiment, the lens barrel 2 is provided with an internal thread structure with a length of approximately 25 mm. When the first positioning member 3, the first lens 5, and the second positioning member 4 are positioned near the end of the internal thread structure close to the handle 1, the diameter of the light spot can reach 6 mm. When the first positioning member 3, the first lens 5, and the second positioning member 4 are located in the middle of the internal thread structure, the diameter of the light spot can become approximately 4 mm. If a smaller diameter light spot is required, the first positioning member 3, the first lens 5, and the second positioning member 4 can be positioned away from the end of the internal thread structure from the handle 1, and the diameter of the light spot can be further reduced to 2 mm.

[0047] Continue to refer to Figure 2 As shown, in some embodiments, the single-spot handpiece further includes a second lens, a third positioning member, and a fourth positioning member. The outer periphery of both the third and fourth positioning members is provided with an external thread structure. The third and fourth positioning members can engage with the internal thread structure and are adjustablely positioned within the lens barrel 2. The second lens is clamped and fixed between the third and fourth positioning members. The second lens can adjust the laser light passing through the first lens 5. Furthermore, the second lens, the third positioning member, and the fourth positioning member can also change their installation positions within the lens barrel 2, thereby further adjusting the laser light passing through the first lens 5.

[0048] like Figure 2 , Figure 4 As shown, in this embodiment, the lens barrel 2 has a connecting end and an exiting end. The connecting end is used to connect to the handle 1. After passing through the handle 1, the laser can enter the lens barrel 2 from the connecting end and exit the lens barrel 2 from the exiting end. The single-spot handpiece also includes a contact member 6. One end of the contact member 6 has an abutment portion 61, which is used to abut and stabilize the single-spot handpiece. Furthermore, the contact member 6 is detachably installed at the exiting end, thereby facilitating the disassembly and cleaning of the contact member 6.

[0049] Continue to refer to Figure 2 , Figure 4As shown, in this embodiment, the other end of the contact member 6 has an annular connecting portion 62, and the outer periphery of the annular connecting portion 62 is provided with an external thread structure. The aforementioned internal thread structure extends from the exit end into the lens barrel 2, and the annular connecting portion 62 can be threadedly connected to the internal thread structure to detachably install the contact member 6 onto the lens barrel 2.

[0050] Alternatively, in some other embodiments, the annular connecting portion 62 can be installed in the opening of the emission end by interference fitting, thereby enabling the contact member 6 to be detachably installed.

[0051] Furthermore, a protective lens is also provided within the annular connecting part 62. The protective lens is used to seal the output end, and the laser can pass through the protective lens. By using the protective lens, the internal environment of the single-spot handheld device can be sealed and protected without affecting the normal output of the laser, which helps to reduce the failure rate and maintenance cost of the single-spot handheld device.

[0052] Optionally, such as Figure 1 , Figure 4 As shown in this embodiment, the single-spot handpiece also includes a marking structure. The marking structure has at least a first display state and a second display state, and the marking structure can selectively switch to one of the first display state and the second display state, thereby facilitating the operator to identify some information of the single-spot handpiece.

[0053] For example, in this embodiment, the marking structure includes a display lamp 71. The display lamp 71 is mounted on a single-spot handpiece and can emit light in different colors and / or different flashing frequencies to form the first and second display states described above. The display lamp 71 is electrically connected to the treatment machine body, which controls the color and / or flashing frequency of the display lamp 71, thereby facilitating the operator's identification of information such as the spot diameter and the working status of the treatment machine body. For example, when the display lamp 71 remains off, it means the treatment machine body is not powered on; when the display lamp 71 displays green, it indicates that the treatment machine body is working normally; and when the display lamp 71 displays red, it indicates that the treatment machine body has a malfunction.

[0054] Specifically, in this embodiment, the marking structure also includes a lamp holder 72 and a lampshade 73. The lamp holder 72 is detachably mounted on the end of the handle 1 away from the contact member 6, thereby avoiding interference with the surgical field of view and facilitating the disassembly of the lamp holder 72 for cleaning and disinfection of various components. The display lamp 71 is detachably mounted on the lamp holder 72, and the lampshade 73 is mounted on the lamp holder 72. The lampshade 73 can cover and protect the end of the display lamp 71 that is close to the end tube 2. Furthermore, the lampshade 73 is made of a light-transmitting or semi-light-transmitting material, which can enhance the display effect of the display lamp 71 and facilitate observation.

[0055] Optionally, the marking structure also includes at least two decorative tubes 81 with different colors and / or different patterns and / or different protrusions, which are replaceably fitted onto the outside of the handle 1 or the lens barrel 2. Specifically, a recess 21 is provided on the outer wall of the lens barrel 2, and when the lens barrel 2 and the handle 1 are connected, the outer wall surfaces of the lens barrel 2 and the handle 1 can jointly define a mounting groove. The decorative tube 81 can be fitted onto the lens barrel 2 from the connecting end, and after the lens barrel 2 and the handle 1 are connected, it is positioned within the mounting groove. For single-spot handpieces with different spot diameters, decorative tubes 81 with different colors and / or different patterns and / or different protrusions can be installed to distinguish the differences in spot diameter and other related information among multiple single-spot handpieces.

[0056] This utility model also provides a laser therapy device, which includes a therapy device body and a single-spot handpiece as described above. The laser therapy device generates laser light and transmits it to the single-spot handpiece via a light guide arm and other structures, finally outputting the light through the single-spot handpiece with a suitable spot diameter. By rationally selecting the installation positions of the first positioning component 3, the second positioning component 4, and the first lens 5 within the single-spot handpiece, the output phenomenon can be changed to meet different treatment needs without requiring adjustments to the structure of each component. This allows the manufacturer to produce single-spot handpieces with different output phenomena using the same components, significantly reducing the structural cost of the single-spot handpiece. Furthermore, it allows the user to obtain a matching single-spot handpiece according to specific treatment needs and to flexibly adjust it based on changed treatment requirements, greatly reducing the specification, quantity, and management requirements for the single-spot handpiece, thus helping to reduce procurement and management costs.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
