Abstract
Provided are an end tool and a surgical instrument. The end tool of a surgical instrument, which is coupled to one end of a connection part of an external device, includes a first jaw rotatable about a pitch rotation shaft and a second jaw relatively rotatable with respect to the first jaw about a second jaw rotation shaft disposed in the first jaw parallel to the pitch rotation shaft, wherein the first jaw and the second jaw are opposed to each other and perform an opening or closing operation, and the first jaw rotates about the pitch rotation shaft but rotates in a direction opposite to a rotation direction of the second jaw in response to the second jaw rotating about the second jaw rotation shaft.
Claims19
An end tool of a surgical instrument, which is coupled to one end of a connection part of an external device, the end tool comprising:
- a first jaw rotatable about a pitch rotation shaft;
- and
- a second jaw relatively rotatable with respect to the first jaw about a second jaw rotation shaft disposed in the first jaw parallel to the pitch rotation shaft,
- wherein the first jaw and the second jaw are opposed to each other and perform an opening or closing operation, and
- the first jaw rotates about the pitch rotation shaft but rotates in a direction opposite to a rotation direction of the second jaw in response to the second jaw rotating about the second jaw rotation shaft.
A surgical instrument comprising:
- an end tool rotatable in two or more directions;
- a manipulation part controlling rotation of the end tool;
- and
- a connection part extending in a first direction (an X-axis) and having one end portion to which the end tool is coupled and another end portion to which the manipulation part is coupled,
- wherein the end tool includes:
- a first jaw rotatable about a pitch rotation shaft;
- and
- a second jaw relatively rotatable with respect to the first jaw about a second jaw rotation shaft disposed in the first jaw and parallel to the pitch rotation shaft,
- wherein the first jaw and the second jaw are opposed to each other and perform an opening or closing operation, and
- the first jaw rotates about the pitch rotation shaft but rotates in a direction opposite to a rotation direction of the second jaw in response to the second jaw rotating about the second jaw rotation shaft.
