[0031] See appendix Figure 1-8 This application discloses an electric laparoscopic stapler with a communication slip ring, including: a stapler main unit 1, an adapter 2, and a staple cartridge assembly; one end of the adapter 2 is connected to the stapler main unit 1, and the other end is connected to the staple cartridge assembly; the adapter 2 includes: a rotating head 22, a barrel 23, and a lead screw 24, and the adapter 2 can rotate radially 360° when it is engaged with the stapler main unit 1; the adapter 2 also includes a communication slip ring 21, and the adapter 2 is communicatively connected to the stapler main unit 1 through the communication slip ring 21; the communication slip ring 21 includes a fixed part and a rotating part, the fixed part and the rotating part are electrically connected, the rotating part can rotate around the fixed part, the fixed part is fixed to the adapter body, the rotating part is engaged with the rotating head 22 of the adapter 2, and the rotating part rotates synchronously with the rotating head 22 when the rotating head 22 rotates, and the circuit between the rotating part and the fixed part is always connected when the rotating head 22 rotates, so the communication is uninterrupted.
[0032] Furthermore, the stapler main unit 1 includes: a motor and a circuit control main board; an adapter 2 stores adapter information and can identify the specifications and model of the staple cartridge assembly; the adapter information includes: adapter model, adapter expiration date, adapter usage count, etc.; after the stapler main unit 1 is installed with the adapter 2 and the staple cartridge assembly, it communicates with the adapter 2, the circuit control main board reads the adapter information and the specifications and model information of the staple cartridge assembly, and controls the forward and reverse rotation of the motor through a preset program to realize the suturing, cutting, and resetting of the staple cartridge assembly. Specifically, the stapler main unit 1 automatically calls the system preset program that matches the specifications and model of the staple cartridge assembly. The rotation of the motor drives the lead screw 24 to rotate through the motor output shaft. The rotation of the lead screw 24 drives the lead screw nut to move forward or backward, so that the staple cartridge assembly completes the suturing and cutting, and controls the firing stroke of the staple cartridge assembly according to the number of rotations of the motor output shaft, so that the cutting and suturing dimensions of the staple cartridge assembly are more precise.
[0033] Furthermore, the fixed part of the communication slip ring includes: a slip ring rotating shaft 211, a slip ring elastic contact fixing seat 212, and a slip ring elastic contact 213; the rotating part of the communication slip ring includes: a slip ring coil 214, a slip ring fixing housing 215, and a slip ring communication connector 216; wherein, the slip ring elastic contact 213 is in close contact with the slip ring coil 214. There are multiple slip ring elastic contacts 213, which are fixed on the slip ring elastic contact fixing seat 212, and after being fixed to the slip ring elastic contact fixing seat 212, the slip ring elastic contacts 213 are mounted on the slip ring rotating shaft 211. The slip ring elastic contact fixing seat 212 is provided with positioning holes 2122. The number of positioning holes 2122 corresponds to the number of slip ring elastic contacts 213. Multiple slip ring elastic contacts 213 are respectively set in the positioning holes 2122. The spacing of the slip ring elastic contacts is controlled by the positioning holes 2122 to ensure that the distance between each slip ring elastic contact 213 is the same and consistent with the spacing of the slip ring coil 214. Preferably, the slip ring elastic contacts 213 are fixed to the slip ring elastic contact fixing seat 212 by soldering. After soldering, the slip ring elastic contacts 213 and the slip ring elastic contact fixing seat 212 are fixed on the slip ring rotating shaft 211. The slip ring elastic contact fixing seat 212 is provided with positioning bosses 2121 on both sides, and the corresponding position of the slip ring rotating shaft 211 is provided with a slot 2111. The positioning bosses 2121 and the slots 2111 cooperate to prevent the slip ring elastic contact 213 and the slip ring elastic contact fixing seat 212 from moving back and forth relative to the slip ring rotating shaft 211. Preferably, there are two positioning bosses 2121 and two slots 2111 on each side.

The slip ring coil protrusion 2141 is fixed after passing through the slip ring housing through hole 2152 and the communication connector through hole 2161 in sequence. Preferably, the slip ring protrusion 2141 passes through the slip ring housing through hole 2152 and is fixed to the slip ring communication connector 216 by soldering, thereby ensuring that the slip ring protrusion 214 and the slip ring communication connector 216 are firmly welded.
[0035] The fixed part and the rotating part of the communication slip ring are assembled separately, and then the assembled fixed part and the assembled rotating part are assembled together. Because the inner diameter of the slip ring coil 314 is smaller than the cumulative size of the slip ring rotating shaft 211, the slip ring elastic contact fixing seat 212, and the slip ring elastic contact 213, when the slip ring elastic contact 213 and the slip ring coil 214 are engaged, the slip ring elastic contact 213 is an elastic part, which ensures that the slip ring coil 214 can always be in close contact with the slip ring elastic contact 213 when rotating, thereby ensuring that the line communication is uninterrupted.
