In the invention, because the matching ring 1421 is in interference fit with the C-shaped groove 122, the rotating shaft 1411 can only drive the matching ring 1421 to move upwards, and when the upward movement force of the rotating shaft is lost, the matching ring 1421 cannot move downwards under the action of the friction force between the matching ring 1421 and the groove wall of the C-shaped groove 122, so that the indicating mechanism is in one-way adjustment.
The working principle of the invention is as follows:
an RFID chip used for storing instrument information on the instrument seat 10 is arranged in the instrument seat 10, the instrument information generally comprises the use times of the instrument, the highest use times and an instrument unique identification code, and the information in the RFID chip is written in an encrypted mode; a reader-writer used for reading and writing the instrument information in the RFID chip is arranged in the surgical equipment, the RFID chip is decrypted and read by the reader-writer, the instrument information on the instrument seat 10 can be obtained or modified, and the specific content of the information in the RFID chip cannot be decrypted under the condition of no authorization;
calculating the angle step length of the rotation part 141 required by increasing the use times of the instrument for one time according to the maximum use times of the instrument, the length of the upper area of the indication block 1423 and the movement distance of the indication block 1423 corresponding to the rotation angle of the rotation part 141 in the vertical direction, and after the instrument is used each time, controlling the corresponding motor base output shaft to rotate the angle step length so as to increase the use times of the instrument for one time and reflect the increase through the movement of the upper area of the indication block 1423;
the rotating part 141 on the instrument base 10 rotates to the initial position, the instrument base 10 is installed in a butt joint mode with the adapter, the butt joint disc 1413 of the rotating part 141 is in butt joint with the butt joint bulge of the adapter through the butt joint groove 1414 of the rotating part, the motor base output shaft drives the rotating part 141 to rotate synchronously in a low-torque output mode, and when the motor is moved to the position of the indicating part 142, the motor is locked to obtain the current position of the rotating part 141, so that the corresponding instrument use times are obtained; after the instrument is used, the corresponding motor base output shaft is controlled to rotate by the angle step length (at the moment, the torque output by the motor base output shaft is larger than the friction force of the indicating piece 142 in the C-shaped groove 122, so that the indicating piece 142 can be driven to rotate), the using frequency of the instrument is increased once, and the using frequency is recorded into the RFID chip; if the used times of the instruments are detected to reach the maximum used times, the instruments are discarded.
When an accident occurs during the use of the instrument, and the instrument cannot be used continuously, the wrench can be inserted into the wrenching groove 1415, and the rotating member 141 is manually controlled to rotate to the red display area of the indicating hole 111, so that active failure treatment is performed; and because of unidirectional adjustment, the failure operation of the instrument is in an irreversible manner.
