[0052] The high-energy laser beam of the laser oral treatment instrument treats the oral cavity tissue. After the laser is generated inside the laser oral treatment instrument, the laser is transmitted to the light emitting tip through the light transmission assembly, and is emitted to the tissue inside the patient's oral cavity through the light emitting tip, has the advantages of fast cutting, small injury, high efficiency, etc., compared with the traditional cutting mode, the oral surgery implemented by the laser oral treatment instrument has lower intraoperative pain and better postoperative recovery effect.

[0053] The laser oral treatment instrument usually comprises a laser generator and an operating handle. The laser generator is a device for generating laser, which is usually large in size and needs to be additionally configured with a support and a roller for cooperation and movement. A light transmission assembly is further arranged between the laser generator and the operating handle, and the laser generated by the laser generator is transmitted to the operating handle through the light transmission assembly, and the operating personnel releases a high-energy laser beam through the operating handle to implement oral treatment.

[0054] The laser oral treatment instrument in the prior art has problems of complex structure, large size and inconvenient movement, therefore, the laser generator and the operating handle must be arranged separately. During the implementation of the surgery, the light transmission assembly between the laser generator and the operating handle will always pull the operating handle, and considering that the laser drop point is required to be very accurate during the oral treatment process, the pulled operating handle will certainly cause inconvenience to the operating personnel.

[0055] As shown in Figure 1 and Figure 2 In order to solve the above problems, the utility model provides a kind of oral treatment instrument laser generating device, including support outer shell body 1, quartz glass tube 2, luminous crystal 3, pump flash lamp 4, total reflection light collecting layer 5 and refracting mirror assembly 6.Support outer shell body 1 plays the role of structural support, and quartz glass tube 2, luminous crystal 3, pump flash lamp 4, total reflection light collecting layer 5 and refracting mirror assembly 6 etc. Structure is directly or indirectly arranged on support outer shell body 1.Quartz glass tube 2 is transparent structure, for fixed luminous crystal 3 and pump flash lamp 4.

[0056] The support outer shell 1 is a hollow cylindrical structure, the quartz glass tube 2 is fixedly arranged in the support outer shell 1, the quartz glass tube 2 is a transparent long strip structure, the quartz glass tube 2 is provided with a first fixed pipeline 201 and a second fixed pipeline 202, the first fixed pipeline 201 and the second fixed pipeline 202 are arranged along the length direction of the quartz glass tube 2, the first fixed pipeline 201 and the second fixed pipeline 202 are circular pipelines, and the first fixed pipeline 201 and the second fixed pipeline 202 are parallel to each other.

[0057] The luminescent crystal 3 is fixedly arranged in the first fixed pipeline 201, the luminescent crystal 3 is a long strip structure, the luminescent crystal 3 is provided with a laser working medium, one end of the luminescent crystal 3 is provided with a total reflection end face, and the other end of the luminescent crystal 3 is provided with a semi-transparent end face; the pump flash lamp 4 is fixedly arranged in the second fixed pipeline 202. Since the first fixed pipeline 201 and the second fixed pipeline 202 are parallel to each other, the luminescent crystal 3 and the pump flash lamp 4 are also parallel to each other, which can maximize the light receiving area of the luminescent crystal 3, that is, the light emitted by the pump flash lamp 4 can be maximally received by the luminescent crystal 3.

[0058] The total reflection light collecting layer 5 is arranged on the outer side of the quartz glass tube 2; the laser generated by the pump flash lamp 4 and the luminescent crystal 3 is emitted from the semi-transparent end face, refracted through the refractive mirror assembly 6, and then emitted through the laser emission tip 7 fixedly arranged at the front end of the support outer shell 1.

[0059] In combination with the above structure, the working principle of the laser generating device of the oral cavity treatment instrument is as follows: in the quartz glass tube 2, the pump flash lamp 4 emits light in a flashing manner, the light emitted by the pump flash lamp 4 irradiates the luminescent crystal 3, the laser working medium in the luminescent crystal 3 is excited to emit laser, at this time, the laser is directed in various directions, the laser directed in various directions is limited in the luminescent crystal 3 by the total reflection light collecting layer 5, and oscillates between the total reflection end face and the semi-transparent end face at both ends of the luminescent crystal 3, and finally forms a high-energy laser beam with consistent direction which is emitted from the semi-transparent end face.

[0060] At this time, the direction of the high-energy laser beam is consistent with the axial direction of the support outer shell 1. It can be imagined that such a direction is not convenient for the operator to use: when the operator holds the structure, it is difficult to control the laser landing point in such a narrow space as the oral cavity. Therefore, the laser generated by the pump flash lamp 4 and the luminescent crystal 3 is emitted from the semi-transparent end face, and then emitted through the laser emission tip 7 fixedly arranged at the front end of the support outer shell 1. The laser emission tip 7 changes the propagation direction of the laser, forms a certain angle with the device, and is more convenient for operation.

[0061] Based on the above structure, it is no longer necessary to set a light transmission assembly between the laser generator and the operating handle as in the conventional technology, and the laser generated by the laser generator is transmitted to the operating handle through the light transmission assembly, but the functions of the handle and the laser are integrated: the pump flash lamp 4 emits light to stimulate the laser working medium in the luminescent crystal 3 to generate laser, the laser oscillates in the total reflection light collecting layer 5 and then exits from the semi-transparent end face, and then is refracted to the laser exit tip 7 through the refractive mirror assembly 6, and the above structure forms a handle structure through the supporting outer shell 1, which has the advantages of simple structure and convenient operation.

[0062] As shown in Figure 3 , preferably, a refractive mirror mounting part 8 is provided on the supporting outer shell 1, the refractive mirror mounting part 8 includes an inner threaded connection part 801 and a refractive mirror fixing sleeve 802, the refractive mirror fixing sleeve 802 is a cylindrical structure; the refractive mirror assembly 6 includes a refractive mirror fixing cap 601 and a refractive mirror body 602, the refractive mirror fixing cap 601 is formed with an outer threaded connection part 603, and the refractive mirror body 602 is a cylindrical structure; the refractive mirror assembly 6 is arranged on the refractive mirror mounting part 8 through the threaded cooperation of the inner threaded connection part 801 and the outer threaded connection part 603, and the refractive mirror body 602 is sleeved in the refractive mirror fixing sleeve 802.

[0063] In the technical solution, the refractive mirror mounting part 8 is used to fix the refractive mirror assembly 6 on the supporting outer shell 1, so as to change the laser propagation direction through the refractive mirror assembly 6, and facilitate the operator to grasp and use. The refractive mirror assembly 6 is mounted and fixed on the refractive mirror mounting part 8 through the threaded cooperation of the inner threaded connection part 801 and the outer threaded connection part 603, and at this time the refractive mirror body 602 is sleeved in the refractive mirror fixing sleeve 802.

[0064] Based on the above structure, the laser advancing direction is changed through the refractive mirror mounting part 8, which is more convenient for the operator to accurately control the laser landing point, and the refractive mirror assembly 6 is assembled through the inner threaded connection part 801 and the outer threaded connection part 603, so that the position of the refractive mirror assembly 6 can be adjusted, the laser refraction point is changed by adjusting the cooperation degree of the inner threaded connection part 801 and the outer threaded connection part 603, so as to change the optical path, and it is convenient for the operator to change the laser optical path according to the actual demand, so as to better couple with the laser exit tip 7.

[0065] As shown in Figure 4 and Figure 5As shown, preferably, the refractive mirror body 602 is provided with a sealing gasket 9; when the refractive mirror assembly 6 is fixedly arranged on the refractive mirror mounting member 8, the sealing gasket 9 abuts against the refractive mirror mounting member 8. The sealing gasket 9 improves the sealing performance of the device, prevents water vapor from entering the interior of the device during use, and improves the reliability of the device.

[0066] As shown in Figure 3 As shown, the refractive mirror fixing sleeve 802 is provided with a fixing member limiting ring 803 and a gasket limiting ring 804; the fixing member limiting ring 803 is formed between the inner threaded connecting portion 801 and the refractive mirror fixing sleeve 802, and the gasket limiting ring 804 is located at the bottom of the refractive mirror fixing sleeve 802.

[0067] When the refractive mirror assembly 6 is fixedly arranged on the refractive mirror mounting member 8, the refractive mirror fixing cap 601 abuts against the fixing member limiting ring 803, and the sealing gasket 9 abuts against the gasket limiting ring 804. During installation of the refractive mirror assembly 6, the sealing gasket 9 first abuts against the gasket limiting ring 804, and the refractive mirror fixing cap 601 gradually presses the sealing gasket 9 against the gasket limiting ring 804. The sealing gasket 9 fills the gap between the refractive mirror assembly 6 and the refractive mirror mounting member 8, thereby improving the waterproof performance of the device. After installation, the refractive mirror fixing cap 601 abuts against the fixing member limiting ring 803, thereby preventing over-installation of the refractive mirror fixing cap 601 and preventing the refractive mirror fixing cap 601 from being removed.

[0068] Based on the above structure, the refractive mirror fixing cap 601 and the sealing gasket 9 cooperate with the fixing member limiting ring 803 and the gasket limiting ring 804, respectively, thereby improving the structural stability of the device, ensuring that the refractive mirror fixing cap 601 and the entire refractive mirror assembly 6 remain stable during operation and that the laser light path remains controllable, and further improving the sealing performance of the device.

[0069] As shown in Figure 4 and Figure 5 As shown, preferably, the bottom of the refractive mirror fixing cap 601 is recessed inward to form a body fixing groove 604; the body fixing groove 604 is located at the center of the bottom of the refractive mirror fixing cap 601, and the refractive mirror body 602 is fixedly arranged in the body fixing groove 604 by adhesive. The body fixing groove 604 is provided on the refractive mirror fixing cap 601, and the refractive mirror body 602 is fixedly arranged in the body fixing groove 604 by adhesive, thereby forming a firm structure through a simple connection method.

[0070] In the device, the refractive mirror fixing cap 601 is not suitable to be externally arranged outside the support shell 1 in view of the integrity and safety of the device, otherwise it may scratch external devices or patients during use. Ideally, the refractive mirror fixing cap 601 is flush with the support shell 1, but this may cause problems in the process of disassembling the refractive mirror fixing cap 601.

[0071] As shown in Figure 2 , Figure 4 and Figure 5 , preferably, the top of the refractive mirror fixing cap 601 is provided with three force blind holes 605 for cooperating with the driving tool to rotate the refractive mirror fixing cap 601 to achieve the installation and disassembly of the refractive mirror assembly 6.

[0072] Based on the three force blind holes 605 on the top of the refractive mirror fixing cap 601, a special clamp is matched, and three protruding parts in the clamp are inserted into the three force blind holes 605 correspondingly, so that the clamp and the refractive mirror fixing cap 601 form a whole. When disassembly is needed, the refractive mirror fixing cap 601 can be driven to rotate through the clamp, which is convenient for controlling the cooperation degree between the refractive mirror fixing cap 601 and the refractive mirror mounting part 8, and adjusting or disassembling the refractive mirror mounting part 8.

[0073] As shown in Figure 6 , preferably, the front end of the support shell 1 is provided with a sharp end mounting sleeve 10, which is a cylindrical structure; the laser emitting sharp end 7 is a cylindrical structure, which is fixedly sleeved in the sharp end mounting sleeve 10; at one end close to the refractive mirror assembly 6, the outer diameter of the laser emitting sharp end 7 is smaller than the inner diameter of the sharp end mounting sleeve 10, and a temperature control gap 11 is formed between the laser emitting sharp end 7 and the sharp end mounting sleeve 10.

[0074] When laser irradiation is applied to an object, the temperature of the object will rise. After coupling, the laser is ideally fully incident into the optical fiber, but in reality part of it will scatter out. In this technical solution, the scattered part of the laser will cause the temperature of the sharp end mounting sleeve 10 to rise, which may seriously burn the optical fiber and cause equipment damage.

[0075] In order to solve this problem, a temperature control gap 11 is formed between the laser emitting sharp end 7 and the sharp end mounting sleeve 10, so as to isolate the laser emitting sharp end 7 and the sharp end mounting sleeve 10. When the laser is coupled into the optical fiber on the laser emitting sharp end 7, it is prevented from irradiating on the sharp end mounting sleeve 10 to cause temperature rise and avoid failure.

[0076] Preferably, the quartz glass tube 2 is elliptical in cross section, and the first fixed pipe 201 is located above the second fixed pipe 202. The elliptical structure can accommodate the first fixed pipe 201 and the second fixed pipe 202, so that the structure of the device is more compact, and it is more convenient for the operator to grasp and operate.

[0077] Preferably, the total reflection end face is a total reflection film, and the semi-transparent end face is a 20% semi-reflection film. After the laser is generated, the laser oscillates between the total reflection film, the 20% semi-reflection film and the total reflection light collecting layer 5, so as to improve the oscillation efficiency and ensure the effective formation of the high-energy laser beam.

[0078] Specifically, the total reflection light collecting layer 5 is a magnesium oxide powder layer or a barium sulfate powder layer. The use of the magnesium oxide powder layer or the barium sulfate powder layer as the total reflection light collecting layer 5, in combination with the total reflection end face and the semi-transparent end face at both ends of the luminescent crystal 3, can fully utilize the laser generated by the luminescent crystal 3 and improve the luminescent efficiency.

[0079] It should be understood that the application of the present application is not limited to the above examples, and those skilled in the art can make improvements or changes according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the present application.
