DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0031] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0032] The present application embodiment discloses an energy detection hand tool. Figures 1 to 7 , the energy detection hand tool provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0033] See also Figure 1 to Figure 7 , the embodiment of the present application discloses an energy detection handpiece, which is applied to laser treatment equipment. The disclosed energy detection handpiece includes a housing 100, a beam sampler 200 and a sampling module 300. Among them, see Figure 1 , Figure 2 and Figure 3 The housing 100 is a basic component of the energy detection handpiece, and can provide an installation and protection basis for the beam sampler 200 and the sampling module 300. Specifically, the housing 100 has a light guide channel 110 and a sampling channel 120 intersecting the light guide channel 110, that is, the sampling channel 120 intersects with the light guide channel 110. Exemplarily, the light guide channel 110 penetrates the housing 100 along the axial direction of the housing 100, and the extension direction of the sampling channel 120 is perpendicular to the extension direction of the light guide channel 110. The laser beam generated by the laser generator can be emitted to the patient's skin through the light guide channel 110.

[0034] In an embodiment of the present application, the beam sampler 200 is disposed in the light guiding channel 110, and the setting position of the beam sampler 200 corresponds to the sampling channel 120. The beam sampler 200 is inclined relative to the extension direction of the light guiding channel 110. When the laser beam enters the light guiding channel 110, most of the laser light in the laser beam passes through the beam sampler 200 and is emitted toward the patient's skin for laser treatment, while a small part of the laser light is reflected by the beam sampler 200 and is emitted toward the sampling channel 120, and then is collected by the sampling module 300 in the sampling channel 120.

[0035] Exemplarily, the sampling module 300 can be a light detection sensor. The laser energy detected by the sampling module 300 can reflect the total energy of the laser beam incident in the shell 100 and the laser energy for laser treatment acting on the patient's skin. By setting the beam sampler 200 to adopt a spectroscopic sampling method, the energy of the laser beam can be monitored, and the operator can adjust the total energy of the laser beam incident in the shell 100 according to the sampling measurement result, thereby adjusting the laser energy for laser treatment directly acting on the patient's skin, thereby avoiding excessive or insufficient laser energy.

[0036] The inventors found during the research that the spot size formed by the laser beam emitted by the beam sampler 200 is relatively large, so that the laser energy received by the sampling module 300 is relatively large, and the sampling module 300 may be easily damaged due to the large laser energy. Based on this situation, in the embodiments of the present application, please refer to Figure 4 The housing 100 is provided with a light-transmitting hole 130 for connecting the light-guiding channel 110 and the sampling channel 120. Part of the laser beam reflected by the beam sampler 200 is transmitted to the sampling channel 120 through the light-transmitting hole 130. That is to say, the laser energy entering the sampling channel 120 is limited by the setting of the light-transmitting hole 130, thereby preventing the sampling module 300 from being damaged by strong laser irradiation.

[0037] For further technical solutions, please continue to refer to Figure 3 The energy detection hand tool may further include an attenuation plate 400, which is disposed in the sampling channel 120. The attenuation plate 400 is disposed between the beam sampler 200 and the sampling module 300. The attenuation plate 400 can absorb or reflect part of the laser beam, thereby effectively reducing the intensity of the laser passing through the attenuation plate 400, thereby protecting the sampling module 300.

[0038] See also Figure 2 , Figure 3 and Figure 6 The energy detection handpiece further includes a cylindrical adapter 500, which is an axial through structure. The cylindrical adapter 500 is disposed in the housing 100, and the cylindrical adapter 500 is coaxially disposed with the housing 100. In the embodiment of the present application, the proximal end surface of the cylindrical adapter 500 is inclined relative to its axial direction, and the proximal end of the cylindrical adapter 500 has a step surface 510, and the beam sampler 200 can be embedded in the step surface 510. Based on this technical solution, when assembling the beam sampler 200 and the housing 100, the beam sampler 200 can be first embedded in the step surface 510 at the proximal end of the cylindrical adapter 500, and then the cylindrical adapter 500 with the beam sampler 200 is installed in the housing 100. Under such a setting, based on the transfer function of the cylindrical adapter 500, the difficulty of manufacturing the housing 100 can be reduced, and the convenience of installing the beam sampler 200 in the housing 100 and the stability of the installation position can be improved.

[0039] For further technical solutions, see Figure 2 , Figure 3 , Figure 5 and Figure 7A first positioning protrusion 140 is provided on the inner wall of the shell 100. After the cylindrical adapter 500 is arranged in the shell 100, along the extension direction of the shell 100 from the proximal end thereof to the distal end thereof, the cylindrical adapter 500 can abut against the first positioning protrusion 140 to be assembled in place in the axial direction of the shell 100. Exemplarily, the first positioning protrusion 140 can be an annular structure. When the cylindrical adapter 500 abuts against the first positioning protrusion 140, the annular first positioning protrusion 140 can ensure the stability of the abutment of the cylindrical adapter 500 and prevent the cylindrical adapter 500 from tilting axially relative to the shell 100.

[0040] It should be noted that after the cylindrical adapter 500 is abutted against the first positioning protrusion 140 to be installed in place, the cylindrical adapter 500 can be fixed in the shell 100 by snapping, gluing or abutting, that is, the beam sampler 200 can be assembled and fixed in the shell 100.

[0041] In some embodiments of this application, please continue to refer to Figure 3 The energy detection hand tool may further include a push piece 600, which is threadedly engaged in the housing 100. For example, the push piece 600 is located at the proximal end of the housing 100, and is provided with an external thread. The housing 100 is provided with an internal thread on the inner wall of the light guide channel 110. When the push piece 600 is screwed into the spiral, the push piece 600 applies a push force to the cylindrical adapter 500, so that the cylindrical adapter 500 abuts against the first positioning protrusion 140. That is to say, the cylindrical adapter 500 can be assembled in place in the axial direction of the housing 100 by the joint abutment of the push piece 600 and the first positioning protrusion 140.

[0042] In a further technical solution, the push member 600 can be an annular structure, and the proximal end of the cylindrical adapter 500 has an abutment plane 520, and the annular push member 600 abuts against the abutment plane 520, thereby ensuring the stability of the abutment between the two and allowing the cylindrical adapter 500 to move stably as a whole.

[0043] In some embodiments of the present application, one of the cylindrical adapter 500 and the first positioning protrusion 140 is provided with a positioning recess 141, and the other is provided with a second positioning protrusion 530. For example, see Figure 5 and Figure 7 The positioning recess 141 is provided on the first positioning protrusion 140, and the second positioning protrusion 530 is provided on the distal end of the cylindrical adapter 500. When the cylindrical adapter 500 abuts against the first positioning protrusion 140, the second positioning protrusion 530 is located in the positioning recess 141, that is, the second positioning protrusion 530 is positioned and matched with the positioning recess 141. In this way, the cylindrical adapter 500 can be restricted from rotating along the circumferential direction of the shell 100.

[0044] Based on the aforementioned technical solution, by limiting the rotation of the cylindrical adapter 500 in the axial direction and the circumferential direction of the shell 100, the position and posture of the cylindrical adapter 500 after being assembled to the shell 100 can be determined, thereby ensuring the position and posture of the beam sampler 200 in the shell 100, so that most of the laser light passing through the beam sampler 200 can be collimated and emitted along the axial direction of the shell 100, and a small part of the laser light reflected by the beam sampler 200 can be stably emitted to the sampling module 300.

[0045] In the embodiment of the present application, the beam sampler 200 is a glass plate, the light incident surface and the light exit surface of the beam sampler 200 are both planes, and the light incident surface and the light exit surface of the beam sampler 200 are parallel, that is, the beam sampler 200 cannot produce a converging or diverging effect on the laser beam, thereby ensuring that most of the laser beam used for treatment and a small part of the laser beam used for sampling can be collimated and emitted.

[0046] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0047] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
