Description

Technical Field

[0002] Laser therapy devices have been widely used in oral diagnosis and treatment, and have shown unique advantages in soft and hard tissue cutting, root canal irrigation, etc. During the treatment process, doctors usually need to select different fiber heads and laser parameters according to the location and size of the patient's oral lesions and formulate corresponding treatment plans. Therefore, the laser handpiece of the laser therapy device needs to be equipped with a variety of fiber heads. The differences in the fiber heads are length, fiber core diameter, bending needle angle, maximum acceptable laser power, energy, etc.

[0003] Due to the small size of the optical fiber head, it is not easy to mark its outer surface. Therefore, the color of the optical fiber head is mainly used to characterize different models, and the model, batch number and related UDI code and other product information are marked on the outer packaging of the optical fiber head. When in use, doctors and nurses need to manually determine the model of the optical fiber head according to the color of the optical fiber head, and configure the parameters of the corresponding model of the optical fiber head on the display screen of the therapeutic instrument, and then perform surgical treatment. On the one hand, the manual determination of the model of the optical fiber head has low recognition accuracy, and the corresponding configuration parameters of different models of optical fiber heads are different, which may cause potential medical accidents. On the other hand, the model scalability of the optical fiber head is not high, and it can only be distinguished by adding new colors, which increases the cost of material control. In addition, because the optical fiber head will be in direct contact with the patient during the treatment process, in order to ensure the safety of equipment use and patient treatment, the optical fiber head needs to be traced and managed. However, if it is only traced through the outer packaging of the optical fiber head, it is easy to be counterfeited, and it is impossible to achieve true traceability, and it is difficult to ensure the quality and regularity of the optical fiber head.

In this way, the two contacts of the antenna coil arranged on the identification ring can be smoothly contacted and cooperated with the two metal sheets arranged on the handpiece respectively, so that the main controller can be smoothly connected to the antenna coil through the metal sheets. The antenna coil can obtain and identify the radio frequency signal with product information emitted by the electronic tag through non-contact identification.

The main controller parses and processes the signal to obtain the product information of the corresponding optical fiber head.

[0022] Specifically, when the product information of the optical fiber head stored in the electronic tag includes the model of the optical fiber head, the main controller can obtain the model of the optical fiber head from the electronic tag of the optical fiber head.

[0035] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0037] See also Figure 1-Figure 4 The present embodiment provides a laser hand tool, which includes an optical fiber head 100, an identification ring 200 and a hand piece 300; the optical fiber head 100 is installed with an electronic tag 110, and the electronic tag 110 stores product information of the optical fiber head 100, and the product information includes one or more of the model of the optical fiber head 100, encrypted verification information, a global unique identification code, the number of times it has been used, the batch number, the manufacturer code, and the production date; the identification ring 200 is provided with an antenna coil, and the hand piece 300 is provided with two metal sheets 311; the optical fiber head 100 is connected to the identification ring 200, and the identification ring 200 is connected to the hand piece 300 and a first positioning structure is provided between the two, and the first positioning structure can perform circumferential positioning of the identification ring 200 and the hand piece 300; the contacts 211 at both ends of the antenna coil 210 are respectively in contact with the two metal sheets 311, and the two metal sheets 311 are used to connect the main controller.

[0038] During assembly, the identification ring 200 can be first installed on the handpiece 300, and then the optical fiber head 100 can be installed on the identification ring 200. Under the action of the first positioning structure, the identification ring 200 and the handpiece 300 can be connected together at a specific relative circumferential position. In this way, the two contacts 211 of the antenna coil 210 arranged on the identification ring 200 can be smoothly contacted and matched with the two metal sheets 311 arranged on the handpiece 300 respectively, so that the main controller can be smoothly connected to the antenna coil 210 through the metal sheets 311. The antenna coil 210 can obtain the radio frequency signal with product information emitted by the electronic tag 110 in a non-contact identification manner and identify it. The identified signal can be transmitted to the main controller via the contacts 211 at both ends of the antenna coil 210 and the two metal sheets 311. The main controller parses and processes the signal to obtain the product information of the corresponding optical fiber head 100.

[0039] Specifically, when the product information of the optical fiber head 100 stored in the electronic tag 110 includes the model of the optical fiber head 100, the main controller can obtain the model of the optical fiber head 100 from the electronic tag of the optical fiber head 100 by itself. On the one hand, the step of manually judging the model of the optical fiber head 100 by the base color of the optical fiber head 100 itself is eliminated, and basically no mistakes will occur, which can greatly reduce the risk of potential unexpected accidents. On the other hand, for optical fiber heads 100 of different models, it is only necessary to store the model information of the corresponding optical fiber head 100 in the electronic tag 110 installed thereon to realize the model identification of the optical fiber head 100. There is no need to configure different base colors for optical fiber heads 100 of different models, and it can be expanded arbitrarily, which is convenient for the management of a series of processes such as product production, storage, and circulation, and reduces the cost of material control. In the case where the product information of the optical fiber head 100 stored in the electronic tag 110 includes the encrypted verification information, global unique identification code, batch number, manufacturer code, and production date of the optical fiber head 100, the main controller can obtain the traceability information of the product from the electronic tag 110 of the optical fiber head 100. The encrypted verification information and the global unique identification code are not easy to be cracked and counterfeited, and can achieve true traceability, and can ensure the quality and regularity of the optical fiber head 100. In the case where the product information of the optical fiber head 100 stored in the electronic tag 110 includes the number of times it has been used, the main controller can obtain the number of times the optical fiber head 100 has been used from the electronic tag 110 of the optical fiber head 100, and then determine whether the optical fiber head 100 meets the use requirements. For example, for disposable consumables, if the number of times it has been used is 0, it means that the optical fiber head 100 is qualified and meets the use requirements; if the number of times it has been used is 1, it means that the optical fiber head 100 has been used and does not meet the use requirements, which can greatly reduce safety hazards.

[0040] Therefore, the laser handpiece provided in this embodiment has high recognition accuracy and scalability of the optical fiber head 100, and can ensure the quality and regularity of the optical fiber head 100; in addition, the setting of the first positioning structure between the identification ring 200 and the handpiece 300 can also ensure the reliability of signal transmission, so that the main controller can smoothly obtain product information such as the model of the optical fiber head 100; and the optical fiber head 100 and the identification ring 200 adopt a non-contact identification method to transmit signals, which can reduce or even eliminate the impact of frequent replacement of the optical fiber head 100 on the reliability of signal transmission.

[0041] In fact, the main controller is provided with an RFID reader, and the RFID reader can read the product information of the optical fiber head 100 stored in the electronic tag 110 .

[0042] The optical fiber head 100 and the identification ring 200 are detachably connected via a locking structure, so that the optical fiber head 100 can be smoothly replaced, and the identification ring 200 and the handpiece 300 can be used for a long time.

[0043] The antenna coil 210 is preferably disposed at a location of the identification ring 200 close to the optical fiber head 100 .

[0044] Specifically, a slot 221 can be provided on one of the identification ring 200 and the handpiece 300, and a positioning pin 321 can be provided on the other. The slot 221 and the positioning pin 321 are used as the above-mentioned first positioning structure. When the identification ring 200 and the handpiece 300 are assembled, the relative circumferential position of the identification ring 200 and the handpiece 300 is adjusted so that the positioning pin 321 can be smoothly inserted into the slot 221. In this way, it can be ensured that the identification ring 200 and the handpiece 300 maintain a specific relative circumferential position after the assembly is completed, thereby achieving the effect of circumferential positioning.

[0045] In the specific structure of the handpiece 300, a hand tool liner 310 and a sensor control shell 320 are provided, the sensor control shell 320 is put on the outside of the hand tool liner 310, and a second positioning structure is provided between the sensor control shell 320 and the hand tool liner 310, so that the sensor control shell 320 and the hand tool liner 310 are circumferentially positioned by using the second positioning structure, so that the sensor control shell 320 and the hand tool liner 310 maintain a specific relative circumferential position after the assembly is completed; a metal sheet 311 is provided on the outer wall of the head end of the hand tool liner 310, and The two contacts 211 of the antenna coil 210 are arranged on the inner wall of the identification ring 200. During assembly, the head end of the hand tool liner 310 can be inserted into the identification ring 200, and the identification ring 200 and the sensor control shell 320 can be connected through the above-mentioned first positioning structure. In this way, under the action of the first positioning structure and the second positioning structure, the identification ring 200 and the hand tool liner 310 can maintain a specific relative circumferential position, thereby ensuring smooth contact and cooperation between the metal sheet 311 and the two contacts 211 of the antenna coil 210.

[0046] Specifically, a card slot 221 can be opened on the end face of the identification ring 200 facing the sensor control shell 320, and a positioning pin 321 can be set on the end face of the sensor control shell 320 facing the identification ring 200. The card slot 221 and the positioning pin 321 are snap-fitted together, and the card slot 221 and the positioning pin 321 are used as the above-mentioned first positioning structure. After the identification ring 200 and the sensor control shell 320 are assembled, the card slot 221 and the positioning pin 321 will be hidden between the identification ring 200 and the sensor control shell 320, which will not affect the appearance of the laser handpiece, and the aesthetics are better, and dirt is not easy to accumulate in the gap between the card slot 221 and the positioning pin 321.

[0047] A clamping hole can be provided on one of the hand tool liner 310 and the sensor control shell 320, and a plug-in connector 312 can be provided on the other. The clamping hole and the plug-in connector 312 are used as the second positioning structure. When the hand tool liner 310 and the sensor control shell 320 are assembled, the relative circumferential position of the hand tool liner 310 and the sensor control shell 320 is adjusted so that the plug-in connector 312 can be smoothly inserted into the clamping hole. In this way, the hand tool liner 310 and the sensor control shell 320 can maintain a specific relative circumferential position after assembly, thereby achieving the effect of circumferential positioning. Specifically, a clamping block and an elastic member can be provided in the specific structure of the plug-in connector 312. When the position of the clamping block corresponds to the clamping hole, the elastic member can push the clamping block into the clamping hole to achieve the clamping positioning of the clamping block and the clamping hole; wherein, the clamping hole is preferably provided at a position close to the tail end of the sensor control shell 320.

[0048] A wiring groove can be opened on the hand tool inner liner 310, one end of the wiring groove is extended to the position of the metal sheet 311, and the other end is extended to the rear end of the hand tool inner liner 310; a cable 330 is passed through the wiring groove, one end of the cable 330 is connected to the two metal sheets 311, and the other end of the cable 330 is extended along the wiring groove to the rear end of the hand tool inner liner 310, and the cable 330 is used to realize an indirect wired connection between the two metal sheets 311 and the main controller, and the signal transmission reliability is better. The cable 330 is buried in the wiring groove, which is not easy to affect the plug-in assembly of the hand tool inner liner 310 and the identification ring 200, and is not easy to affect the sleeve assembly of the hand tool inner liner 310 and the sensor control shell 320.

[0049] Two pins 331 can be set at one end of the cable 330, and the two pins 331 are connected to the two metal sheets 311 respectively; accordingly, two branch grooves are set at one end of the wiring trough, and the two pins 331 of the cable 330 are matched with the two branch grooves respectively, which is equivalent to that the cable 330 only has two pins 331 at the end to respectively connect with the two metal sheets 311, and the other parts are integrated into a single cable and extended along a wiring trough, which is convenient for the processing of the wiring trough and the installation of the cable. Specifically, the two pins 331 can be connected to the two metal sheets 311 by welding.

[0050] The above-mentioned cable 330 is preferably a radio frequency coaxial cable, which can reduce the cross-sectional area of ​​the cable 330, so that the cable 330 can be completely hidden in the wiring groove and is not easily exposed. It is also beneficial to reduce the groove depth and width of the wiring groove, reduce the degree of damage to the structure of the hand tool liner 310 itself, and ensure the structural strength of the hand tool liner 310; in addition, the radio frequency coaxial cable has better transmission performance and can improve the reliability of signal transmission.

[0051] In the specific structure of the optical fiber head 100, a plastic base 120 can be provided, and the electronic tag 110 can be embedded in the plastic base 120. On the one hand, the plastic base 120 is a non-metallic structure, which can improve the reliability of the non-contact identification method between the electronic tag 110 and the antenna coil 210; on the other hand, the electronic tag 110 is embedded in the plastic base 120, which can reduce the impact of the external environment on the electronic tag 110 and ensure the integrity of the electronic tag 110.

[0052] In the specific structure of the identification ring 200, a plastic shell 220 may be provided, and the antenna coil 210 may be embedded in the plastic shell 220. On the one hand, the plastic shell 220 is a non-metallic structure, which can improve the reliability of the non-contact identification method between the electronic tag 110 and the antenna coil 210; on the other hand, the antenna coil 210 is embedded in the plastic base 120, which can reduce the impact of the external environment on the antenna coil 210 and ensure the integrity of the antenna coil 210. Specifically, the material of the plastic shell 220 may be polypropylene.

[0053] Specifically, the fiber optic head 100 also has an optical fiber 130, a metal steel tube 140 and a core ferrule 150. The metal steel tube 140 and the core ferrule 150 are fixed on the plastic base 120 and the central axes of the three coincide. The optical fiber 130 is inserted into the metal steel tube 140 and the core ferrule 150. The hand tool inner shell 310 has an optical focusing cavity 313. The head end of the hand tool inner shell 310 is provided with a tight coupling fixing flange 314. The core ferrule 150 is plugged into the tight coupling fixing flange 314. The tail end of the hand tool inner shell 310 is connected to the transmission optical fiber 315. The laser emitted by the main controller can enter the transmission optical fiber 315. The optical focusing cavity 313 can adjust the laser light beam passing through the transmission optical fiber 315, and finally couple it to the end face center of the fiber optic head core 150.

[0054] The hand piece 300 further comprises a fixed tailstock 340 , and the tail end of the hand tool liner 310 is fixedly connected to the fixed tailstock 340 .

[0055] Preferably, model identification information can be set on the outer wall of the optical fiber head 100, so that production line personnel and user-end operators can distinguish the model of the optical fiber head 100. Specifically, the optical fiber head model can be laser screen printed on the outer wall of the optical fiber head 100.

[0056] As an alternative, different models of optical fiber heads 100 may be set to different colors, which also facilitates production line personnel and user-end operators to distinguish the models of optical fiber heads 100.

[0057] The electronic tag 110 specifically includes a chip 112 and an antenna 111. The electronic tag 110 can activate the chip 112 through coupling energy and transmit a radio frequency signal carrying its own information.

[0058] This embodiment also provides a laser therapy device, which includes a main controller, a display screen and a laser handpiece. The laser handpiece is connected to the main controller via an optoelectronic hybrid cable 400, and the display screen is communicatively connected to the main controller.

[0059] The laser therapy device provided in this embodiment can realize optoelectronic connection with the laser handpiece through the optoelectronic hybrid cable 400, so that the main controller can smoothly read the product information of the electronic tag 110 on the optical fiber head 100, and can transmit the product information of the optical fiber head 100 to the display screen for display. Doctors and nurses can determine whether the optical fiber head 100 is genuine and meets the use requirements based on the product information of the optical fiber head displayed on the display screen, and can configure corresponding parameters according to the model of the optical fiber head 100. The main controller can control the operation of the laser handpiece under the parameters.

[0060] Specifically, the optoelectronic hybrid cable 400 can be connected to the optical focusing cavity 313 of the laser handpiece through the transmission optical fiber 315 , and can be connected to the cable 330 of the laser handpiece.

[0061] It should be noted that the laser therapy device provided in this embodiment has all the advantages of the above-mentioned laser handpiece because it has the above-mentioned laser handpiece. The optical fiber head 100 has high recognition accuracy and scalability, which can ensure the quality and regularity of the optical fiber head 100, and can also ensure the transmission reliability of the signal, reducing or even eliminating the impact of frequent replacement of the optical fiber head 100 on the reliability of signal transmission.

[0062] When the usage times of the optical fiber head 100 do not meet the requirements, the main controller can also force the optical fiber head 100 to be discarded, so that the optical fiber head 100 cannot work.

[0063] A storage module can be set in the main controller, and the storage module can store configurable mode parameters corresponding to different models of optical fiber heads 100. In this way, after the main controller reads the model of the optical fiber head 100, the treatment mode interface parameters on the display screen can be automatically updated, and doctors and nurses can select the parameters corresponding to the indications on the display screen to start treatment. The operation is convenient, and parameter configuration is not prone to errors, thereby improving safety.

[0064] In addition, during the use of the optical fiber head 100, the main controller can also perform statistical calculations on the laser usage time and the accumulated laser energy of the optical fiber head 100, and send a write operation instruction to the RFID module after use. When the accumulated laser usage time or the accumulated laser energy of the corresponding optical fiber head 100 reaches the limit value, the main controller can issue an alarm to ensure the quality reliability of the optical fiber head 100 each time it is used.

[0065] The working steps of the laser therapy device provided in this embodiment include:

[0066] 1. After the device is powered on, each functional component is initialized and waits for the device to be ready;

[0067] 2. After the device is ready, the display screen prompts "Install the fiber head". When the fiber head 100 is installed, the main control board reads the electronic tag 110 through the RFID module. The electronic tag 110 starts the chip 112 by coupling energy, and then emits a radio frequency signal with its own information. After the RFID module reads the signal, it is sent back to the main control board for corresponding analysis and processing;

[0068] 3. The main control board can transmit the parsed product information such as the model and the number of times used to the device display screen for display. In addition, the label verification and identification is completed according to the encrypted verification information and the globally unique identification code returned by the electronic tag 110. When the optical fiber head 100 is identified as a genuine and usable state, the main control board synchronizes the model information of the optical fiber head 100 to the display screen;

[0069] 4. The device has its own storage unit, and the configurable mode parameters corresponding to the fiber head model have been pre-saved in the storage unit. According to the identified fiber head model, the treatment mode interface parameter interface on the display screen is synchronously updated. At this time, the doctor can select the parameters corresponding to the indication on the display screen and start treatment;

[0070] 5. During the treatment, the main control board performs statistical calculations on the laser usage time and the accumulated laser energy. After the treatment is completed, the main control board sends a write operation instruction to the RFID module to mark the number of times the electronic tag 110 is used.
