Title:
KNOB ASSEMBLY AND CYLINDRICAL ANASTOMAT
Document Type and Number:
WIPO Patent Application WO/2020/125675
Kind Code:
A1
Abstract:
A knob assembly and a cylindrical anastomat. The knob assembly comprises a knob body (1), a clutch member, and a knob rear cover. The knob body (1) is provided with a first matching member (11). When the knob body (1) rotates, a screw (6) is driven to move along the axial direction of the anastomat. The clutch member is provided with a second matching member (21). A press spring (3) is provided between the knob rear cover and the clutch member. The knob assembly is divided into the knob body (1) and the clutch member. Before the drag force experienced by the knob body (1) reaches a preset value, the clutch member is rotated to drive the knob body (1) to rotate, and the knob body (1) can drive a nail anvil component (83) to move along the axial direction of the anastomat to get close to a nail bin (82). After the drag force experienced by the knob body (1) reaches the preset value, the clutch member cannot drive the knob body (1) to rotate. In this case, the knob assembly enters an invalid state, and the gap between the nail anvil component (83) and the nail bin (82) stays unchanged so that the tissue is not excessively squeezed.
