To solve the above technical problem, the technology of automatically identifying component information has emerged. Automatically identifying component information is a medical device intelligent technology. Its main function is to identify the key components and other attribute information of laparoscopic instruments through an instrument for identifying laparoscopic instruments, such as key information like instrument model, expiration date, remaining quantity of consumables (tissue clips, titanium clips, suturing staples, etc.), and then automatically transmit this information to the controller to help doctors use these instruments more accurately and efficiently during the operation, improving the operation efficiency and operation safety. This technology is very important for laparoscopic surgery and is also an important direction for the development of modern medical technology.

[0003] In the prior art, the model is determined by the energization position of the travel-assembled electrode sheet, and the controller uses different programs for different devices. However, due to the limitation of the structural space, the number of component models that can be identified is limited and cannot fully meet the surgical requirements. And because the components are used multiple times, it is necessary to read the consumable information in the components and write the latest information in real time. The prior art cannot achieve real-time communication update and read the internal information of the components. Summary of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] In this article, "upper", "lower", etc. are only used to represent the relative positional relationship between relevant parts, rather than limiting the absolute positions of these relevant parts.

[0032] See the attached Figures 1-10 , a laparoscopic medical device, comprising: a main unit 1000 and a component 2000, wherein the component is detachably mounted on the main unit, the main unit includes an identification circuit 1200, the component includes an identity confirmation structure, and the identity confirmation structure includes the following three types: resistive type, chip type or resistive-chip type; wherein, the resistive-type identity confirmation structure includes an identification resistor, and the identification resistor has different resistance values, and different resistance values correspond to different categories and models of components; the chip-type identity confirmation structure includes a chip, and the first component information is stored in the chip; the resistive-chip type identity confirmation structure includes both a chip and an identification resistor; the identification circuit can identify the resistance values of the chip and the identification resistor to determine the type of the identity confirmation mechanism. If the identity confirmation structure is of the resistive type, the identification circuit reads the resistance value of the identification resistor and queries the second component information list stored in the identification circuit to confirm the component information; if the identity confirmation structure is of the chip type, the identification circuit reads the first component information stored in the chip, and writes the main unit information and the component usage information into the chip; if the identity confirmation structure is of the resistive-chip type, the identification circuit reads the resistance value and queries the second component information list stored in the identification circuit while reading the first component information, and writes the main unit information and the component usage information into the chip; the identification circuit adjusts the main unit parameters according to the first component information and / or the second component information.

[0033] The resistive type identity confirmation structure has a relatively low cost and fast identification speed. However, it cannot directly store information or write information. The resistive type identity confirmation structure is suitable for disposable components, such as stapler components; the EEPROM chip stores more information. The EEPROM chip in the chip type stores information such as the component model, the number of consumables, and the sterilization status, and can write information. However, its identification speed is slower than that of the resistive type. The resistive chip type combines the advantages of the two types. It can use the identification resistor to identify the component model, which speeds up the component identification speed, can quickly connect, and quickly match the component type. At the same time, since it includes an EEPROM chip, it can write host information and component usage information. The above two identity confirmation mechanisms are suitable for components containing consumables, such as: staplers, tissue closure clips, titanium clip forceps, hernia repair devices, etc. In actual use, the above three types of identity confirmation structures can be selected according to the actual component type and actual needs.

[0034] Further, the host 1000 includes a barrel 1100 and an identification circuit 1200. The barrel 1100 is embedded with a barrel thin film circuit 1110. The barrel thin film circuit 1110 is provided with a barrel contact A 1111a and a barrel contact B 1111b. The barrel thin film circuit 1110 is electrically connected to the identification circuit 1200.

[0035] The component 2000 is provided with an identification fuse block 2100. The identification fuse block 2100 is equipped with a component thin film circuit and two component communication contacts (2111a, 2111b). The two component communication contacts can be respectively connected to the barrel contact A pole and the barrel contact B pole. Specifically, the component thin film circuit includes a first component thin film circuit 2110a, a second component thin film circuit 2110b, or a third component thin film circuit 2110c. The first component thin film circuit 2110a includes an EEPROM chip 2113 and a first component communication contact and a second component communication contact. The second component thin film circuit 2110b includes an EEPROM chip 2113 and an identification resistor 2112 and a third component communication contact and a fourth component communication contact. The third component thin film circuit 2110c includes an identification resistor 2112 and a fifth component communication contact and a sixth component communication contact.

[0036] The EEPROM chip 2113 of the component 2000 using the first component thin-film circuit 2110a stores the first component information, specifically including: component model, total number of consumables, remaining number of consumables used, production date, sterilization time, expiration date, and other information. When installing the component 2000, the component 2000 is inserted into the barrel 1100. The first component communication contact and the second component communication contact are respectively connected to the barrel contact A 1111a and the barrel contact B 1111b. The other end of the barrel thin-film circuit 1110 is connected to the host identification circuit 1200 provided in the host. The identification chip in the host identification circuit realizes the identification, information reading and writing of the component 2000.

[0037] The component 20000 using the second component thin-film circuit 2110b is provided with an identification resistor 2112 and an EEPROM chip 2113. The EEPROM chip 2113 stores the first component information, specifically including: component model, total number of consumables, remaining number of consumables used, production date, sterilization time, expiration date, and other information. When installing the component 2000, the component 2000 is inserted into the stapler barrel 1100. The third component communication contact and the fourth component communication contact are respectively connected to the barrel contact A 1111a and the barrel contact B 1111b. The other end of the barrel thin-film circuit 1110 is connected to the host identification circuit 1200 provided in the host. Reading the resistance value information of the identification resistor 2112 realizes the identification of the component 20000. At the same time, the first component information stored in the EEPROM chip 2113 can be read, and the information stored in the component 20000 can be read and written.

[0038] The component 2000 using the third component thin-film circuit 2110c. When installing the component 2000, the component 2000 is inserted into the barrel 1100. The fifth component communication contact and the sixth component communication contact are respectively connected to the barrel contact A 1111a and the barrel contact B 1111b. The other end of the barrel thin-film circuit 1110 is connected to the host identification circuit 1200 provided in the host. Reading the resistance value of the identification resistor 2112 and querying the stored second component information realizes the identification of the component 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 a component 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 means that no component 2000 is connected, prompting the doctor that the component is not installed. The host 1000 is waiting and continuously detecting the voltage value of the voltage-dividing circuit 1220. When the component 2000 is connected to the host 1000, the host single-chip microcomputer 1210 detects the change in the voltage value of the voltage-dividing circuit 1220. The single-chip microcomputer 1210 recognizes that a component 2000 is connected. Through the analog-to-digital function inside the single-chip microcomputer 1210, it obtains the digital quantity of the voltage VR of the voltage-dividing voltage VR / 1-Wire 1222 of the current voltage-dividing circuit 1220, and obtains the current voltage value VR through calculation by the single-chip microcomputer 1210. Since the resistance value of the voltage-dividing resistor R1 1221 is known, through the formula R2 = (R1 × VR) / (VCC - VR), the single-chip microcomputer 1210 calculates the resistance value of the identification resistor R2 2112. The host queries the second component information list according to the resistance value of the identification resistor R2 2112. Different resistors are used in the resistance type and resistor chip type identity confirmation structures to represent different component specifications and models.

[0040] If the host obtains the resistance value of the identification resistor, that is, the identity confirmation structure type is the resistance type, it queries in the list of corresponding component types and resistance values stored in the single-chip microcomputer 1210 to obtain the second component information, including: the current component model, model, adjusts the host parameters, and records the component.

[0041] If the host recognizes a chip, that is, the component 2000 type is the chip type, the host single-chip microcomputer 1210 starts the 1-Wire communication protocol to communicate with the component 2000 and 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 used, the production date, the sterilization time, the expiration date, etc. The host 1000 also writes information such as the host number and usage time 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 information of the current component.

[0042] If the host recognizes that the chip simultaneously obtains the resistance value of the recognition resistor and the type of component 2000 is a resistor chip type, first query in the corresponding list of component types and resistor values stored in the microcontroller 1210 to obtain the second component information, including: the current component type and model, adjust the host parameters, and record the component. And at the same time, the host microcontroller 1210 starts 1-Wire protocol communication with the component 2000 to read 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 used, the production date, the sterilization time, the expiration date, etc. The host 1000 also writes information such as the host number and usage time 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 information of the current component.

[0043] If the microcontroller 1210 of the host recognizes that the component 2000 is not in the component list stored in the microcontroller, prompt the doctor that the component is not compatible and ask to replace it with a compatible component.

[0044] After each use of the component 2000, the host 1000 stores the usage situation of the component and the consumable quantity in the corresponding storage area of the memory of the host microcontroller 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 consumable quantity in the component 2000 is used up, prompt the doctor to replace the component; when the usage times of the host 1000 are exceeded, prompt the doctor to replace the host. The above-mentioned consumables refer to a certain number of clips contained in specific components such as tissue closure clips and titanium clips. The quantity information is stored in the component chip and recognized by the host. Each closure consumes one, and the microcontroller counts and updates the quantity information stored in the component in real time, and gives a prompt after exhaustion.

[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 usage information. When the host 1000 is connected again, the host reads the last usage information in the EEPROM chip 2113 of the component through the 1-Wire communication interface 1212. The host microcontroller 1210 judges usage information such as whether the component has been matched with other hosts and whether the quantity can continue to be used. When all the information meets the requirements, the host microcontroller 1210 executes the corresponding program, prompts the doctor that it can be used continuously, otherwise prompts the corresponding error information, informing the doctor that the component 2000 is abnormal.
