TRAVEL DETECTION STRUCTURE AND CONTROL METHOD THEREFOR, ELECTRIC STAPLER, AND MEDICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/045563
Kind Code:
A1
Abstract:
A travel detection structure and a control method therefor, an electric stapler, and a medical device. The travel detection structure is used for detection of a trigger action of a medical device, and comprises a support portion, a transmission portion, and a detection portion. The support portion serves as a support structure of the travel detection structure; the transmission portion is arranged in the support portion in a penetrating manner, and can axially move inside the support portion; and the detection portion is fixed on the support portion and comes into contact with the transmission portion by means of the support portion. One end of the transmission portion is connected to an operation end of a medical device, and when the transmission portion axially moves in the support portion, the transmission portion sequentially comes into contact with different detection positions on the detection portion to complete travel detection of the transmission portion relative to the support portion, so that the operation end executes a trigger action according to the travel detection. The problem of excessive squeezing can be completely avoided by means of travel detection, and the detection with different detection positions, such as second trigger lock detection for a staple cartridge, can be realized.
