Abstract

The present application provides a needle driving assembly under an endoscope, and a suturing device. The needle driving assembly under an endoscope comprises: a housing assembly, an arc-shaped suture needle, a rotating body, a driving assembly, a control member, a snap-fitting member and a limiting member. The control member cooperates the driving assembly to control the rotating body to rotate, and the rotating body drives the snap-fitting member to rotate in a first direction or a second direction, so that the arc-shaped suturing needle rotates by one circle relative to the housing assembly, so as to thread human tissue with a needle one time. The structure has a rational design, is compact, and is convenient to use, and by means of cooperation of the rotating body, the driving assembly, the control member, the snap-fitting member and the limiting member, the arc-shaped suturing needle is driven to rotate by 360 degrees repeatedly relative to the housing assembly, so as to achieve the suturing of the human tissue, thereby improving operation efficiency. In addition, the movement direction of the control member is at least partially perpendicular to the rotation direction of the rotating body and the arc-shaped suturing needle, thereby conveniently observing the suture state of the arc-shaped suturing needle and adapting to the suture operation under a flexible or rigid endoscope.
