When the assembly 2000 is installed, the assembly 2000 is inserted into the barrel 1100, the first assembly communication contact and the second assembly communication contact are connected with the barrel contact A 1111a and the barrel contact B 1111b respectively, the other end of the barrel thin film circuit 1110 is connected with the host recognition circuit 1200 provided in the host, the recognition chip in the host recognition circuit is recognized, and the recognition and information reading and writing of the assembly 2000 are realized.

[0037] The assembly 2000 using the second assembly thin film circuit 2110b is provided with a recognition resistor 2112 and an EEPROM chip 2113, and the EEPROM chip 2113 stores the first assembly information, specifically including: assembly model, total number of consumables, remaining number of consumables, production date, sterilization time, expiration date, and the like. When the assembly 2000 is installed, the assembly 2000 is inserted into the stapler barrel 1100, the third assembly communication contact and the fourth assembly communication contact are connected with the barrel contact A 1111a and the barrel contact B 1111b respectively, the other end of the barrel thin film circuit 1110 is connected with the host recognition circuit 1200 provided in the host, the resistance value information of the recognition resistor 2112 is read to realize the recognition of the assembly 2000, the first assembly information stored in the EEPROM chip 2113 can be read, and the information stored in the assembly 2000 can be read and written.

[0038] The assembly 2000 using the third assembly thin film circuit 2110c. When the assembly 2000 is installed, the assembly 2000 is inserted into the barrel 1100, the fifth assembly communication contact and the sixth assembly communication contact are connected with the barrel contact A 1111a and the barrel contact B 1111b respectively, the other end of the barrel thin film circuit 1110 is connected with the host recognition circuit 1200 provided in the host, the resistance value of the recognition resistor 2112 is read and the second assembly information stored is inquired to realize the recognition of the assembly 2000.

[0039] The host includes a single-chip microcomputer and a voltage dividing circuit. After the host 1000 is powered on, the single-chip microcomputer detects the voltage value of the voltage dividing circuit to determine whether the assembly is connected, and calculates the resistance value of the identification resistor through the voltage value of the voltage dividing circuit. Specifically, after the host is powered on, the single-chip microcomputer 1210 starts to cyclically detect the voltage value of the voltage dividing circuit 1220. When the voltage value is VCC, it represents that no assembly 2000 is connected, prompting the doctor that the assembly is not loaded, and the host 1000 is waiting and continuously detecting the voltage value of the voltage dividing circuit 1220. When the assembly 2000 is connected to the host 1000, the host single-chip microcomputer 1210 detects the change of the voltage value of the voltage dividing circuit 1220, and the single-chip microcomputer 1210 identifies that the assembly 2000 is connected. Through the analog-to-digital function inside the single-chip microcomputer 1210, the digital quantity of the voltage value VR of the voltage dividing voltage VR / 1-Wire 1222 of the current voltage dividing circuit 1220 is obtained, and the current voltage value VR is calculated through the single-chip microcomputer 1210. Since the resistance value of the voltage dividing resistor R1 1221 is known, the resistance value of the identification resistor R2 112 is calculated through the formula R2=(R1×VR) / (VCC-VR). The host queries the second assembly information list according to the resistance value of the identification resistor R2 112, and the resistance type and resistance chip type identity confirmation structure use different resistors to represent different assembly specifications.

[0040] If the host obtains the resistance value of the identification resistor, that is, the identity confirmation structure type is the resistance type, the corresponding list of the assembly type and the resistance value stored in the single-chip microcomputer 1210 is queried to obtain the second assembly information, including: the current assembly model, the model, adjusting the host parameters, and recording the assembly.

[0041] If the host identifies the chip, that is, the assembly 2000 type is the chip type, the host single-chip microcomputer 1210 starts the 1-Wire communication protocol and the assembly 2000 communication to read the contents of each register of the EEPROM chip 2113 of the assembly. Through the information stored in different registers of the assembly EEPROM chip 2113, the first assembly information can be obtained, including: the current assembly 2000 model, the total number of consumables, the remaining number of consumables, the production date, the sterilization time, the expiration date, etc. The host 1000 also writes the host number, the use time, etc. information into the EEPROM chip 2113 of the assembly through the 1-Wire communication interface 1212. The host 1000 executes the program corresponding to the assembly 2000, adjusts the corresponding parameters, and informs the doctor of the current assembly information.

[0042] If the host recognizes that the chip obtains the resistance value of the identification resistance at the same time, the component 2000 is of the resistance chip type, first, the host queries the corresponding list of the component type and the resistance value stored in the single-chip microcomputer 1210, obtains the second component information, including: the current component type, model, adjusts the host parameters, and records the component. At the same time, the host single-chip microcomputer 1210 starts the 1-Wire protocol communication and the component 2000 communication, reads the contents of each register of the EEPROM chip 2113 of the component. Through the information stored in different registers of the component EEPROM chip 2113, the first component information can be obtained, including: the model of the current component 2000, the total number of consumables, the remaining number of consumables, the production date, the sterilization time, the expiration date, etc. The host 1000 also writes the host number, use time and other information into the EEPROM chip 2113 of the component through the 1-Wire communication interface 1212. The host 1000 executes the program corresponding to the component 2000, adjusts the corresponding parameters, and informs the doctor of the current component information.

[0043] If the single-chip microcomputer 1210 of the host recognizes that the component 2000 is not in the component list stored in the single-chip microcomputer, the doctor is prompted that the component is not suitable, and the suitable component needs to be replaced.

[0044] After each use of the component 2000, the host 1000 stores the use condition and the number of consumables of the component in the corresponding storage area of the memory of the host single-chip microcomputer 1210, and at the same time, writes the same information into the EEPROM chip 2113 of the component through the 1-Wire communication interface 1212. When the number of consumables in the component 2000 is used up, the doctor is prompted to replace the component; when the use times of the host 1000 are exceeded, the doctor is prompted to replace the host. The above-mentioned consumables refer to a certain number of clamps contained in a specific component such as a tissue closure clamp, a titanium clamp, etc. The number information is stored in the component chip and recognized by the host. Each time the closure is consumed, the single-chip microcomputer counts and updates the number information stored in the component in real time, and prompts when it is exhausted.

[0045] When the component 2000 is not used up and the host 1000 is disconnected, the EEPROM chip 2113 of the component stores the last use information. When the host 1000 is connected again, the host reads the last use information in the EEPROM chip 2113 of the component through the 1-Wire communication interface 1212, the host single-chip microcomputer 1210 judges whether the component matches other hosts, whether the number can continue to be used, and other use information. When all the information is satisfied, the host single-chip microcomputer 1210 executes the corresponding program, prompts the doctor that it can continue to be used, otherwise, prompts the corresponding error information, and informs the doctor that the component 2000 is abnormal.
