Electric bending device for surgical operating instrument and surgical operating instrument

Abstract

The invention relates to the technical field of medical instruments and discloses an electric bending device and a surgical operating instrument. The electric bending device comprises a driving assembly for supplying power to the bending of an end executor of the surgical operating instrument; the driving assembly comprises a follower, a threaded screw rod and a motor; an output shaft of the motor is in driving connection with the threaded screw rod; the follower is in threaded fit with the threaded screw rod and is in driving connection with the end executor. According to the electric bending device provided by the invention, the bending of an executing part in the end executor can be electrically driven, and the continuity and the stability for controlling the bending of the execution part in the end executor by the surgical operating instrument are improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an electric bending device for a surgical instrument and the surgical instrument. Background technique [0002] Surgical instruments under the laparoscope have less trauma to the patient, and the surgical effect is good, which can greatly reduce the pain caused to the surgical patient. [0003] Taking the cutting and stapler as an example, the cutting and stapler includes an operating handle, an elongated body, and an end effector; the operating handle is used to be held and operated by the user to provide control and driving, and the far side of the operating handle (close to the user during operation) The side of the user is the proximal side, and the side away from the user is the far side) is connected to the end effector through the elongated body, and the end effector is used to cut and suture the tissue of the human body cavity under the control of the operatin...

Problems solved by technology

[0006] However, in the cutting and stapler in the prior art, the bending of the executive part in the end effector is manually controlled. During the operation, the performing doctor needs to hold the cutting and stapler with one hand, and then use the other hand to rotate the knob, etc. To control the bending of the actuator in the end effector

[0007] When the cutting and stapling device in the prior art performs the bending operation of the executing part, the hand of the doctor holding the operating handle maintains the overall stability of the cutting and stapling device, and the other hand rotates the knob to control the bending of the executing part. Sometimes it takes a lot of effort to rotate the knob, and the cutting and stapler will vibrate when using both hands. Therefore, when the doctor manually controls the execution part, the manipulation and stability of the operation are poor, and the operation is laborious.
