Abstract

The invention discloses a reset mechanism, an anastomat and a medical instrument. The reset device comprises a first drive mechanism, a first rotary drive mechanism, a one-way rotary drive mechanism and a second rotary drive mechanism; under the effect of external force, the one-way rotary drive mechanism can only conduct one-way rotation in a set direction; the one-way rotary drive mechanism is connected with the second rotary drive mechanism and can drive the second rotary drive mechanism to rotate in the set direction; when the first rotary drive mechanism is in a first state, the first drive mechanism and the first rotary drive mechanism are connected, and rotation of the first rotary drive mechanism can drive the first drive mechanism to act in the set direction; when the first rotarydrive mechanism is in a second state, the first drive mechanism and the second rotary drive mechanism are connected, and rotation of the second rotary drive mechanism can drive the first drive mechanism to act in the set direction. The reset device can realize manual resetting under the condition that a machine is shut down accidentally, and is simple in structure and safe and reliable in usage.

Description

technical field [0001] The invention belongs to the technical field of surgical medical instruments, relates to a stapler, in particular to a reusable stapler and a reset mechanism. Background technique [0002] In recent years, some medical devices with a reset structure have appeared on the market, such as staplers (especially electric staplers), electrosurgical units, and the like. The reset structure of existing medical devices is relatively complicated, and the operation is inconvenient; and the device may not be able to continue to be used normally after being reset, resulting in the scrapping of the device. [0003] An electric stapler is one of the above-mentioned medical devices that need to be reset. If there is a mechanical, electronic or software failure during the use of the electric stapler, and the motor stops working or fails to work normally, the cutting knife cannot be returned by the motor drive. At this time, a fault reset mechanism is needed to allow t...
