There are many kinds of accessories for high-frequency surgical equipment, and the function and effect of each accessory are different. The same high-frequency surgical equipment has multiple electrodes at the same time. Therefore, it is particularly important to identify the high-frequency surgical equipment during the operation.

[0003] Common high-frequency surgical equipment identification is divided into the following types: the first is to be identified by doctors, which is prone to errors, often causing incorrect access to surgical equipment and wasting time; the second is to identify surgical equipment by physical shape, making the output socket of the high-frequency surgical equipment host and the accessory plug into a matching structure, and each output socket of the host is only suitable for one accessory plug, which effectively reduces the incorrect use of the accessory, but the high-frequency surgical equipment host cannot identify the specific ID number of the accessory. The third is to embed an EEPROM chip in the surgical equipment plug, which stores the accessory ID number, and the host microcontroller reads the information in the EEPROM to realize intelligent identification of the accessory ID number, but embedding the EEPROM chip in the plug and establishing a communication interface between the controller and the EEPROM chip will add additional electronic circuits to the surgical equipment plug and the host, increasing the risk of electric shock, technical difficulty, complexity of structural process and manufacturing cost.

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the implementation of the present invention will be clearly and completely described below in conjunction with the drawings in the implementation of the present invention. Obviously, the described implementation is only a part of the implementation of the present invention, not all of the implementations. Based on the implementation of the present invention, all other implementations obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] like Figures 1 to 6 As shown, a high-frequency surgical instrument identification device in one embodiment of the utility model includes a circuit board 1, a photosensitive element 2, an optical fiber 3 and a socket 4. A sampling circuit electrically connected to the photosensitive element 2 is provided on the circuit board 1, and the sampling circuit is used to identify the electrical signal transmitted by the photosensitive element 2. The resistance of the photosensitive element 2 is different under different light intensities. The photosensitive element 2 is electrically connected to the circuit board 1, and the photosensitive element 2 is used to transmit electrical signals to the circuit board 1. The first end of the optical fiber 3 faces the photosensitive element 2, and the socket 4 is penetrated by an optical fiber jack 401 for inserting the second end of the optical fiber 3.

[0025] According to the above structural design, when the plug connected to the high-frequency surgical instrument is inserted into the socket 4, the plug covers the optical fiber jack 401, and the optical fiber 3 in the optical fiber jack 401 cannot receive the external light source. The incident light received by the photosensitive element 2 at the other end of the optical fiber 3 is greatly weakened, and the resistance of the photosensitive element 2 changes, causing the voltage of the sampling circuit on the circuit board 1 to change. The control system can identify whether the high-frequency surgical instrument is plugged into the socket 4 based on the voltage change, activate the corresponding energy output mode, and provide power output to the high-frequency surgical instrument through the circuit board 1.

[0026] In the above operation process, since the detection element for detecting high-frequency surgical instruments at the socket 4 is the optical fiber 3, the number of electronic circuits at the socket 4 is reduced, the electrical isolation and electric shock protection of the high-frequency surgical instrument identification device are improved, and the patient is prevented from receiving accidental electric shock. In addition, after reducing the number of electronic circuits, the anti-interference performance of the high-frequency surgical instrument identification device can also be enhanced.

[0027] In one embodiment, if Figure 2 As shown, two photosensitive elements 2 , two optical fibers 3 and two sockets 4 are provided, the first ends of the two optical fibers 3 face different photosensitive elements 2 , and the second ends are inserted into the optical fiber jacks 401 of different sockets 4 .

[0028] When the high-frequency surgical instrument identification device in the embodiment of the utility model is used to identify surgical electrodes, surgical electrodes are generally divided into monopolar electrodes and bipolar electrodes. The two sockets 4 can be respectively set as a single-stage socket 4 and a bipolar socket 4, and two corresponding sampling circuits are set on the circuit board 1, which are respectively used to identify monopolar electrodes and bipolar electrodes.

[0029] In one embodiment, in order to improve the stability of the end of the optical fiber 3 receiving light and prevent the optical fiber jack 401 from affecting the light incident on the optical fiber 3, the second end of the optical fiber 3 extends as far as possible to the surface of the socket 4. In other embodiments, the second end of the optical fiber 3 may also be appropriately extended a short distance in the direction away from the socket 4.

[0030] In one embodiment, if Figure 3 and Figure 6 As shown, the circuit structure is simplified, and the photosensitive element 2 is mounted on the circuit board 1. In addition, in order to fix the end of the optical fiber 3, the high-frequency surgical instrument identification device also includes an optical fiber holder 5, which is mounted on the circuit board 1. The optical fiber holder 5 is provided with a receiving socket 501 for receiving the photosensitive element 2, and the first end of the optical fiber 3 is inserted into the receiving socket 501.

[0031] In order to facilitate installation of the end of the optical fiber 3 in the optical fiber jack 401, Figure 5 As shown, the high-frequency surgical instrument identification device further includes a pin 6 , which is disposed in the optical fiber jack 401 , and the second end of the optical fiber 3 is inserted in the pin 6 .

[0032] Further, in order to facilitate the removal of the plug 6 or the replacement of the optical fiber 3, the plug 6 and the optical fiber jack 401 can be connected in a detachable manner, for example, the plug 6 can be threadedly connected to the optical fiber jack 401. In other embodiments, the plug 6 and the optical fiber jack 401 can also be connected in a snap-on manner.

[0033] Another embodiment of the utility model provides a high-frequency surgical device, comprising a housing 7, the high-frequency surgical instrument identification device and a power supply 8. The circuit board 1, the photosensitive element 2 and the optical fiber 3 are arranged in the housing 7, and the socket 4 is arranged on the shell wall of the housing 7. The power supply 8 is arranged in the housing 7 and electrically connected to the circuit board 1, and the circuit board 1 is also electrically connected to the socket 4. The circuit board 1 has multiple output modes for providing different output powers to the high-frequency surgical instrument.

[0034] In one embodiment, if Figure 2 As shown, the high-frequency surgical device further comprises a heat dissipation fan 9, which is mounted on one of the shell walls of the shell 7. Preferably, the heat dissipation fan 9 is mounted on one side wall of the shell 7.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
