[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be further described below.

[0032] The present invention proposes a medical gun drill module for realizing battery rental, which includes three parts: a gun drill body 1, a battery 2 and a charger 3; the battery 2 can be detachably installed in the gun drill body 1, and the charger 3 charges the battery 2.

[0033] Specifically, as shown in Figure 1, a schematic diagram of the structure of a rental charger 3 is shown. In this embodiment, the rental charger 3 is equipped with four charging ports 7. Each charging port 7 has a charging electrode and a signal transmission electrode mounted at the bottom for charging the battery 2. A charging management chip is mounted within the charger 3. In this embodiment, the charging management chip utilizes a PFM-type, multi-cell nickel-metal hydride battery charging control integrated circuit chip. The charging management chip connects to four separate charging channels, each of which is independently connected to a charging port 7. This significantly reduces the risk of the device becoming unusable due to a malfunction. Even if a malfunction damages one of the charging channels of the charger 3, the other three channels remain unaffected, allowing the device to continue operating. The charging management chip is also connected to an MCU chip, as shown in Figure 6. The charging management chip collects battery 2 status information and transmits it to the MCU chip. The MCU chip then sends an enable signal to the charging management chip based on the number of times provided by the server and the legitimacy of the battery 2. Based on the enable signal, the battery 2 can be charged or prohibited from charging.

[0034] As shown in Figure 2, the side of the charger 3 is provided with a power interface 4, a network cable interface 5 and a battery 2 number entry interface 6. The power interface 4 is used for charging, and the MCU chip is connected to the server through the network cable interface 5. The operator enters the battery 2 signal into the MCU chip through the battery 2 number entry interface 6, thereby realizing automatic judgment of the legitimacy of the battery 2.

[0035] As shown in Figure 3, it is a schematic diagram of the structure of the battery 2 in the present invention. A positive electrode 7, a negative electrode 8 for charging and discharging, and an electrode 9 for signal transmission are provided on the surface of the battery 2; an intelligent chip is installed inside the battery 2. In this embodiment, the intelligent chip adopts a single-chip microcomputer chip. The intelligent chip includes the number information of the battery 2, the power information of the battery 2, and realizes communication and matching between the charger 3 and the gun drill; the intelligent chip is connected to the charging management chip by overlapping the signal electrode sheet. After the signal is connected, the charging management chip inside the charger 3 reads the information inside the intelligent chip and transmits it to the MCU chip for judgment of the battery 2.

[0036] The server includes an APP, which can use the micro program "Bojin Leasing Platform" to recharge the account. After recharging, the transmission connection based on the network signal can increase the available times of the charger 3, thereby charging the battery 2.

[0037] Specifically, the battery 2 rental system for the gun drill module of the present invention operates as follows. The device is primarily rented to medical institutions and includes a charger 3 and battery 2. As shown in Figure 5 , after the operator tops up the device on the app, the user places the battery 2 into the charger 3. If the available count of the charger 3 is not 0, the battery 2 will be charged after 10 seconds, and the available count of the charger 3 will decrease by 1. The charger 3 will then display the charge count. Based on the number of connected batteries 2 and the charge count, the corresponding battery 2 will be charged. Multiple batteries 2 can be charged simultaneously, or a single battery 2 can be charged multiple times based on the charge count. The charge count information is displayed on the charger 3's display screen 10. After charging, the battery 2 is inserted into the gun drill body 1 shown in Figure 4 . The gun drill body 1 establishes communication with the battery 2, and once it recognizes the battery 2 as a valid device, the gun drill is activated for use. Single-wire communication is used between the charger 3, battery 2, and gun drill, improving data transmission, verification, and error correction capabilities. Communication follows a master-initiated, slave-responded mechanism. A CRC checksum mechanism is also provided to ensure data transmission accuracy.

[0038] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any way. Any person skilled in the art who, without departing from the scope of the present invention, makes any equivalent substitution, modification, or other changes to the technical solution and technical content disclosed in the present invention shall be deemed to be within the scope of the present invention and still fall within the scope of protection of the present invention.
