Abstract

The invention relates to the medical instrument technical field, and discloses a bending device and a surgery operation instrument; a bending device drive assembly comprises a drive screw rod; the drive screw rod is arranged on a fixed handle in a rotary manner around an axis; the axis of the drive screw rod is parallel to that of a slender body; the drive screw rod has two treads comprising a left-hand thread and a right-hand thread; a drive rod is screwed with one thread, the other drive rod is screwed with the other thread; far sides of the two drive rods are connected with an end effector; the bending device drive assembly also comprises a rotary sleeve coaxially sleeved outside the drive screw rod; when the rotary sleeve is in a bending adjusting work position, the rotary sleeve is in transmission connection with the drive screw rod through a gear assembly. The rotary sleeve is matched with the gear assembly of the drive screw rod, and the drive screw rod are screwed with the two drive rods with high stability; the rotary angle of the rotary sleeve can be controlled so as to control a bending angle of the end effector against the slender body, so the operation is high in accuracy.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bending device of 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 includes a fixed handle and a firing handle, wherein the fixed handle is used to be held by the user, and the firing handle is used to be held by the user. Operate to provide control and drive. The far side of the operating handle (the side close to the user during operation is the proximal side, and the side away from the user is the far side) is connected to the end effector through an elongated body. Under the control of the o...
