[0003] At present, when laparoscopic staplers are used to anastomose the digestive tract, most of the existing ones require doctors to manually drive the staplers out to perform the anastomosis, which is time-consuming and labor-intensive. In addition, the staplers cannot be squeezed out quickly during manual driving, which reduces the degree of anastomosis. Utility Model Content

[0004] In order to solve the above problems, the purpose of the present utility model is to provide an electric drive structure of a laparoscopic stapler to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes an electric drive structure of a laparoscopic stapler, comprising a handle seat, the handle seat comprising a mounting ring, one end of the mounting ring is threadedly connected to a connector, and one end of the connector is installed with a lower clamping plate;

[0006] A driving mechanism is provided inside the handlebar, and the driving mechanism includes a vertical plate, a second fixing rod, a connecting ring, a first fixing rod and a moving frame, the inner wall of the lower clamping plate is slidably connected with the moving frame that penetrates and extends to the outside of the lower clamping plate, a first fixing rod that penetrates and extends into the connecting head is fixedly installed in the middle of one side of the moving frame, a connecting ring is fixedly installed at one end of the first fixing rod, the inner wall of the handlebar is slidably connected with the vertical plate, a second fixing rod that penetrates and extends into the connecting head is fixedly installed on one side of the vertical plate, and the second fixing rod is threadedly connected to the connecting ring;

[0007] A rack is slidably connected to one side of the inner wall of the handlebar, and the rack is fixedly connected to the vertical plate. A motor is fixedly installed on one side of the inner wall of the handlebar, and a rotating shaft is fixedly installed on the output shaft of the motor. A gear is fixedly installed on one end of the rotating shaft, and the gear is meshingly connected to the rack.

[0008] In one example, a smooth plate is fixedly mounted on the top of the movable frame outside the lower clamping plate.

[0009] In one example, an upper clamping plate is hingedly connected to one end of the connecting head.

[0010] The electric drive structure of the laparoscopic stapler proposed by the utility model can bring the following beneficial effects:

[0011] 1. The electric drive structure of the laparoscopic stapler drives the rotating shaft to rotate by starting the motor, and drives the gear to rotate. Because the gear is meshed with the rack, it can drive the vertical plate to move, and drive the second fixed rod to move. The first fixed rod will be driven to move through the connecting ring, and the moving frame will be driven to move, so that the staples in the lower clamping plate can be squeezed out, which is convenient for subsequent anastomosis. It is driven by the motor to achieve a better anastomosis effect. BRIEF DESCRIPTION OF THE DRAWINGS
