The YAG laser, the light transmission assembly and the light emitting tip are arranged on the shell. In the use process, the laser emitted by the YAG laser is transmitted to the light emitting tip through the light transmission assembly, and after being emitted through the light emitting tip, the high-energy laser beam is used to irradiate the oral tissue. It can be used for decontamination and sterilization of the oral cavity, soft and hard tissue cutting, bone tissue removal and other operations, and can reduce inflammation and promote regeneration and repair of oral tissue.

[0053] In the operation process, if the laser oral treatment instrument is too far from the target part, the laser irradiation precision will be greatly reduced, thereby affecting the treatment effect. Therefore, the front end of the laser oral treatment instrument needs to be close to or even extended into the patient's oral cavity to achieve precise irradiation. On the one hand, the oral environment has a large amount of bacteria, and the special use mode of the laser oral treatment instrument determines that it needs to be thoroughly and effectively disinfected during daily maintenance and between two uses. On the other hand, the internal design of the laser oral treatment instrument is precise, and the high-temperature and high-humidity environment necessary in the disinfection process may cause irreversible damage to the electronic components. In summary, how to simultaneously achieve thorough disinfection and prevent electronic component failure to meet the daily application of the laser oral treatment instrument is a technical problem to be solved in the industry.

When analyzing the technical scheme, the front shell and quick dismounting sleeve 1 are in front, and the rear shell and quick dismounting plug 2 are in back with the laser emission direction as reference.

[0055] The quick dismounting sleeve 1 is a cylindrical structure, the quick dismounting plug 2 is a cylindrical structure, the quick dismounting sleeve 1 and the quick dismounting plug 2 are coaxially arranged, and the quick dismounting plug 2 is detachably inserted into the quick dismounting sleeve 1. The elastic clamping assembly is arranged on the quick dismounting sleeve 1, the clamping cooperation assembly is arranged on the quick dismounting plug 2, and the quick dismounting plug 2 is detachably inserted into the quick dismounting sleeve 1 through the cooperation of the elastic clamping assembly and the clamping cooperation assembly.

[0056] Based on the above structure, under the premise that the quick dismounting sleeve 1 and the quick dismounting plug 2 are fixed to the front shell and the rear shell respectively, the elastic clamping assembly and the clamping cooperation assembly are arranged, the quick dismounting plug 2 is detachably inserted into the quick dismounting sleeve 1 through the cooperation of the elastic clamping assembly and the clamping cooperation assembly, the quick dismounting sleeve 1 and the quick dismounting plug 2 are fixed to each other when needed, laser is emitted for treatment, the quick dismounting sleeve 1 and the quick dismounting plug 2 are separated from each other when disinfection is needed, the fixed or dismounting requirement before and after use is met, complete disinfection is realized through the detachable structure after use, and electronic element failure can be effectively prevented.

[0057] As Figure 3 Preferably, the elastic clamping assembly includes an elastic clamp 3 and a plurality of hard beads 4, the elastic clamp 3 is formed by bending a metal long sheet into a circular arc structure, and the two ends of the metal long sheet form an opening. The opening here means that the head and tail are not connected and do not form a closed circle. When the metal long sheet is bent into a circular arc structure and the head and tail are not connected, the metal long sheet itself has elasticity, that is, when the circular arc structure is subjected to external force, the elastic force will drive it to return to the original state. The technical scheme utilizes the characteristics of the elastic clamp 3 to provide the elastic force required for quick dismounting.

[0058] The elastic clamping hoop 3 is sleeved on the quick release sleeve 1; a plurality of ball movable holes 101 are formed in the side wall of the quick release sleeve 1, the ball movable holes 101 are arranged through the side wall of the quick release sleeve 1, and the hard balls 4 are arranged in the ball movable holes 101 one by one; the elastic clamping hoop 3 applies elastic force to the plurality of hard balls 4 in the direction of the axis of the quick release sleeve 1. Correspondingly, the clamping and matching assembly is a ball clamping groove 201 arranged on the quick release plug 2, and the ball clamping groove 201 is arranged on the outer side of the quick release plug 2 in the circumferential direction.

[0059] In combination with the above structure, the working principle of the quick release structure is analyzed as follows: when the quick release plug 2 is fixed on the quick release sleeve 1, the elastic clamping hoop 3 fixes the hard balls 4 in the ball clamping groove 201 by using the elastic force of the elastic clamping hoop 3, the hard balls 4 are fixed in the ball clamping groove 201, and correspondingly, the quick release plug 2 and the quick release sleeve 1 are combined into an integrated structure. When it is necessary to separate the quick release plug 2 and the quick release sleeve 1 to achieve quick release, an external force is provided by an operator to make the quick release plug 2 and the quick release sleeve 1 have a trend of mutual separation, at this time, the external force drives the hard balls 4 to slide out of the ball clamping groove 201, in this process, the hard balls 4 expand the elastic clamping hoop 3, overcome the elastic force of the elastic clamping hoop 3 and gradually slide out of the ball clamping groove 201, after the hard balls 4 leave the ball clamping groove 201, the quick release plug 2 and the quick release sleeve 1 are separated from each other. When it is necessary to quickly install the quick release plug 2 on the quick release sleeve 1, an external force is provided by an operator to make the quick release plug 2 and the quick release sleeve 1 have a trend of mutual insertion, in this process, the hard balls 4 expand the elastic clamping hoop 3, overcome the elastic force of the elastic clamping hoop 3 and gradually embed in the ball clamping groove 201, after the hard balls 4 embed in the ball clamping groove 201, the quick release plug 2 and the quick release sleeve 1 are inserted and fixed to each other.

[0060] Based on the above structure, the metal long piece is bent into a circular arc structure and an opening is formed on the circular arc structure, the metal long piece forms the elastic clamping hoop 3 by using the elasticity of the metal long piece, and the plurality of hard balls 4 are crimped in the ball clamping groove 201. When no external force is applied, the hard balls 4 are engaged in the ball clamping groove 201, and when an external force is applied, the hard balls 4 can roll out of the ball clamping groove 201, so as to realize the functions of quick installation and quick release.

[0061] As Figure 3As shown, preferably, the elastic clamping hoop 3 is provided with a plurality of ball positioning through holes 301. Preferably, the bottom of the ball movable through hole 101 is provided with a ball limiting ring 102, which is located on the inner side of the sidewall of the quick release sleeve 1, and the inner diameter of the ball limiting ring 102 is smaller than the radius of the hard ball 4.

[0062] The hard ball 4, the ball movable through hole 101 and the ball positioning through hole 301 correspond one by one; the hard ball 4 is movably arranged in the ball movable through hole 101, and the two sides of the hard ball 4 abut against the ball positioning through hole 301 and the ball limiting ring 102 respectively.

[0063] The size of the ball movable through hole 101 is slightly larger than that of the hard ball 4, so as to meet the requirement that the hard ball 4 can move in the ball movable through hole 101; in order to prevent the hard ball 4 from moving excessively, the ball limiting ring 102 is arranged at the bottom of the ball movable through hole 101, and the radius of the ball positioning through hole 301 is smaller than that of the hard ball 4, so as to lift the hard ball 4 by the ball limiting ring 102 and prevent the hard ball 4 from moving excessively inward; the radius of the plurality of ball positioning through holes 301 on the elastic clamping hoop 3 is smaller than that of the hard ball 4, so as to press the hard ball 4 by the elastic force of the elastic clamping hoop 3 and prevent the hard ball 4 from moving excessively outward.

[0064] Based on the above structure, the hard ball 4 is limited in the ball movable through hole 101 by the ball positioning through hole 301 and the ball limiting ring 102, so that the hard ball 4 can realize the quick installation and disassembly function with the ball clamping groove 201.

[0067] The working process of the elastic clamp 3 is analyzed: the hard ball 4 is sleeved in the circular hole, and because the hard ball 4 and the circular hole are both circular, the hard ball 4 abuts on the circular hole, and when the hard ball 4 is driven by an external force, the hard ball 4 and the circular hole will not relatively displace. The hard ball 4 is sleeved in the long hole, and a certain displacement space is reserved. By using this characteristic, when the hard ball 4 is driven by an external force, the hard ball 4 will displace in the long hole. That is, in the elastic clamp 3, the circular hole cooperates with the corresponding hard ball 4 to fix the midpoint of the elastic clamp 3 during the process of being expanded by an external force, and the hard balls 4 located in the two long holes will move outward, slightly move in the long hole in the process, and then expand the elastic clamp 3.
