[0041] See appendix Figure 1-14This application discloses a reusable electric laparoscopic stapler, comprising: a stapler main unit 1, a protective shell 2, an adapter 3, and a staple cartridge assembly; the protective shell 2 is detachably installed outside the stapler main unit 1, and when the protective shell 2 is installed outside the stapler main unit 1, it can serve as a sterile barrier; one end of the adapter 3 is connected to the protective shell 2, and the other end of the adapter 3 is connected to the staple cartridge assembly, and the stapler main unit 1 can communicate with the protective shell 2 and the adapter 3; wherein, the protective shell 2 stores protective shell information, the adapter 3 stores adapter information, and the stapler main unit 1 can read the protective shell information and the adapter information.

[0042] The stapler main unit 1 includes: a handle housing 11, a motor 13, a circuit control main board 14, a handle communication connector 19, and a motor output shaft 20. The motor 13 and the circuit control main board 14 are housed within the handle housing 11. The motor output shaft 20 is connected to the motor 13 to output its rotation. After the stapler main unit 1 is installed with the protective housing 2, adapter 3, and staple cartridge assembly, it can communicate with the protective housing 2 and adapter 3 via the handle communication connector 19. The circuit control main board 14 reads information from the protective housing and adapter, and controls the forward and reverse rotation of the motor 13 through a preset program to achieve suture cutting and resetting of the staple cartridge assembly. The stapler main unit has an independent operating system, and the circuit control main board 14 also stores information about the stapler main unit, including: production information, model information, and number of uses.

[0043] Furthermore, the main unit of the stapler also includes: a motor bracket 12, a rechargeable battery 15, a display screen 16, a trigger / reset switch 17, and a confirmation switch 18. The motor 13 is fixed to the motor bracket 12, the rechargeable battery 15 provides power to the entire electric stapler, and the display screen 16 displays relevant information about the electric stapler. This relevant information includes, but is not limited to: power-on information, self-test information, protective housing information, and adapter information.

[0044] The protective housing 2 includes: a front housing 21, a rear housing 22, a quick connector 23, a rotating shaft 24, and a communication mainboard 25. The front housing 21 and the rear housing 22 can be fixed together to seal the stapler unit, acting as a sterile barrier. Preferably, the front housing 21 and the rear housing 22 are fixed together by snap-fit. The rotating shaft 24 is connected to the motor output shaft 20, transmitting the rotation of the motor 13 to the adapter 3. The protective housing 2 simultaneously serves the functions of communication, motion transmission, and protection and isolation of the stapler unit 1.

[0045] Adapter 3 includes: adapter connector 31, adapter circuit board 32, rotating head 33, barrel 34, and lead screw drive component 35; quick connector 23 is installed and locked with adapter connector 31, thereby connecting the stapler main unit 1 and adapter 3 together. Quick connector 23 allows connection between the handle main unit 1 and adapter 3, making installation convenient and quick, stable and secure after installation, and adapter 3 can be easily disassembled without jamming. Adapter circuit board 32 stores adapter information, including: adapter model, adapter expiration date, and number of times the adapter has been used.

[0046] The circuit board 32 further includes an identification chip that can identify the specifications and model of the staple cartridge assembly. Preferably, the identification chip is a color identification chip 321. The color identification chip 321 determines the information of the staple cartridge assembly based on the different colors of the staple cartridge housing. The information includes the specifications and model of the staple cartridge assembly. The adapter also includes a communication slip ring 37 and an adapter communication connector 36. The communication slip ring 37 is connected to the communication board 25 of the protective housing through the adapter communication connector 36. The circuit board 32 transmits the identified staple cartridge assembly information to the stapler host 1 through the communication slip ring 37, the adapter communication connector 36, and the communication board 25 of the protective housing. The stapler host 1 automatically calls the system preset program that matches the specifications and model of the staple cartridge assembly. The rotation of the motor output shaft 20 drives the rotation shaft 24 to rotate, thereby driving the lead screw 35 to rotate. The rotation of the lead screw 35 drives the lead screw nut to move forward or backward, so that the staple cartridge assembly completes the suturing and cutting. The firing stroke of the staple cartridge assembly is controlled according to the number of rotations of the motor output shaft 20, so that the cutting and suturing dimensions of the staple cartridge assembly are more accurate. The adapter 3 is equipped with a separate electrical component and internally records adapter information. When used in conjunction with the handle host 1, protective shell 2 and staple cartridge assembly, it has the function of automatically identifying the product model of the staple cartridge assembly and transmitting the identified information to the stapler host 1 through the elastic frequency needle. The signal transmission is stable and reliable.

[0047] When the adapter 3 is used with the protective housing 2 and the stapler main unit 1, it has a radial 360° rotation function. After installing the staple cartridge assembly, it has the function of bending the staple cartridge assembly left and right. By moving the teeth 331 of the adapter rotating head 33, the adapter 3 can rotate radially 360°. Turning the steering knob 332 can adjust the left and right bending angle of the staple cartridge assembly. Releasing it can maintain the bending angle of the staple cartridge assembly, and the bending angle of the staple cartridge assembly can be adjusted according to the usage requirements. During surgery, the adapter, together with the staple cartridge assembly, can complete cutting and suturing at various angles, and at any angle, the adapter can ensure stable and smooth cutting, suturing, and post-cutting reset movement of the staple cartridge assembly. In addition, the adapter can also work with the stapler main unit and the staple cartridge assembly to detect tissue thickness. The electric stapler will automatically adjust the output speed of the motor according to the tissue thickness, thereby controlling the forward speed of the staple cartridge assembly cutting blade to complete tissue cutting and suturing more safely and effectively.

[0048] Furthermore, the communication slip ring 37 includes a fixed part and a rotating part, which are electrically connected. The rotating part can rotate around the fixed part. The fixed part is fixed to the adapter body. The rotating part cooperates with the rotating head 33 of the adapter. The rotating part rotates synchronously with the rotating head 33 when the rotating head 33 rotates. When the rotating head 33 rotates, the circuit between the rotating part and the fixed part is always connected, and the communication will not be interrupted.

[0049] Specifically, the fixed part of the communication slip ring 37 includes: a slip ring rotating shaft 371, a slip ring elastic contact fixing seat 372, and slip ring elastic contacts 373; the rotating part of the communication slip ring 37 includes: a slip ring coil 374, a slip ring fixing housing 375, and a slip ring communication connector 376; wherein, the slip ring elastic contacts 373 are in close contact with the slip ring coil 374. There are multiple slip ring elastic contacts 373, which are fixed on the slip ring elastic contact fixing seat 372. After being fixed to the slip ring elastic contact fixing seat 372, the slip ring elastic contacts 373 are mounted on the slip ring rotating shaft 371. The slip ring elastic contact fixing seat 372 is provided with positioning holes, the number of which corresponds to the number of slip ring elastic contacts 373. Multiple slip ring elastic contacts 373 are respectively set in the positioning holes, and the spacing of the slip ring elastic contacts 373 is controlled by the positioning holes to ensure that the distance between each slip ring elastic contact 373 is the same and consistent with the spacing between the slip ring coil 374. Preferably, the slip ring elastic contact 373 and the slip ring elastic contact fixing seat 372 are fixed by soldering; after soldering, the slip ring elastic contact 373 and the slip ring elastic contact fixing seat 372 are mounted on the slip ring rotating shaft 371; the slip ring elastic contact fixing seat 372 is provided with positioning bosses 3721 on both sides, and the corresponding position of the slip ring rotating shaft 371 is provided with a slot 3711. Through the cooperation of the positioning bosses 3721 and the slots 3711, the slip ring elastic contact 373 and the slip ring elastic contact fixing seat 372 are prevented from moving back and forth relative to the slip ring rotating shaft 371. Preferably, there are two positioning bosses 3721 and two slots 3711 on each side.

[0050] The rotating part of the communication slip ring 37 includes: a slip ring coil 374, a slip ring housing 375, and a slip ring communication connector 376. The slip ring housing 375 is composed of upper and lower parts, preferably fixed by a snap fastener 3753. The slip ring coil 374 is fixed by the slip ring housing 375. The inner surface of the slip ring housing 375 has a slip ring coil groove 3751, and the slip ring coil 374 is installed in the groove. There are multiple slip ring coils 374, and the number of slip ring coil grooves 3751 corresponds to the number of slip ring coils 374. The slip ring coil 374 has a slip ring coil protrusion 3741. A slip ring housing through hole 3752 is provided at the position corresponding to the slip ring protrusion 3741, and a communication connector 376 is provided at the position corresponding to the slip ring protrusion 3741. The slip ring protrusion 3741 passes through the slip ring housing through hole 3752 and the communication connector through hole 3761 in sequence. After the slip ring 374 passes through the slip ring housing through hole 3752, it is fixed to the slip ring communication connector 376 by soldering, thereby ensuring that the slip ring 374 and the slip ring communication connector 376 are firmly welded.

[0051] 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 374 is smaller than the cumulative size of the slip ring rotating shaft 371, the slip ring elastic contact fixing seat 372, and the slip ring elastic contact 373, when the slip ring elastic contact 373 and the slip ring coil 374 are engaged, since the slip ring elastic contact 373 is an elastic part, it is ensured that the slip ring coil 374 and the slip ring elastic contact 373 can always maintain close contact when rotating, ensuring that the line communication is uninterrupted.

[0052] This communication slip ring allows the stapler host 1 to detect the installation status of the stapler cartridge assembly when used in conjunction with the stapler cartridge assembly. It also allows the stapler host to detect the specifications and model of the stapler cartridge assembly, ensuring uninterrupted communication when the rotating head rotates 360°, thus satisfying the stapler host's real-time detection of the stapler cartridge assembly.

[0053] The working process of the electric laparoscopic stapler in this application is as follows:

[0054] After the stapler host 1 is powered on, the system performs a self-test, checking the communication, rechargeable battery level, and display screen;

[0055] Install the disposable protective housing 2, fix the front and rear housings, and the system will detect the protective housing 2, read the information of the protective housing, including the expiration date, number of uses, and record the usage information of the protective housing.

[0056] When adapter 3 is installed, the system detects adapter 3 and reads its information, including: expiration date, adapter model, number of uses, and whether the adapter screw nut is at the zero position. If the adapter screw nut is not at the zero position, the system will automatically reset the adapter screw nut to zero.

[0057] After the test is completed, the system prompts you to install the disposable staple cartridge assembly. The system identifies the specifications and model of the staple cartridge assembly by using an identification chip and prompts you to perform a closing and reset operation on the staple cartridge assembly to check whether the staple cartridge assembly is installed in place. At this time, pressing the instrument confirmation button will have no effect.

[0058] After the staple cartridge assembly is tested, adjust the staple cartridge assembly to the appropriate position by rotating the adapter head and / or turning the knob. Press the firing button to close the staple cartridge assembly and clamp the tissue. The instrument firing confirmation button light will flash. Press the confirmation button to fire the instrument. After firing, press and hold or double-click the reset button to reset the instrument. The jaws will open, and the staple cartridge assembly will be removed from the tissue. Adjust the staple cartridge assembly to a straight position and press the firing button to close the staple cartridge assembly. At this time, pressing the firing confirmation button will have no effect. The staple cartridge assembly can only close and reset, but cannot be fired.

[0059] The stapler main unit is reusable, while the protective shell and adapter are single-use. After use, the adapter and protective shell are removed, and the stapler main unit is cleaned for reuse; the adapter and protective shell are not reusable. Used adapters, protective shells, and staple cartridges are disposed of as medical waste. The handle and main unit are reusable, reducing unnecessary waste, alleviating the medical burden on patients, and minimizing environmental pollution from medical waste.
