Abstract

A method comprises rotating a first rotating element to cause rotation of a second rotating element and restricting, by an elongate slot of a first body portion and a pin affixed to a second body portion, a range of rotational motion of first and second jaw portions of a medical instrument. The first jaw portion is coupled to the second jaw portion by the first body portion and the second body portion. The rotation of the second rotating element causes translation of a first actuation element along a rotational axis of the second rotating element. The translation of the first actuation element causes pivotal motion of the first jaw portion towards the second jaw portion about a single pivot pin. The elongate slot of the first body portion and the pin affixed to the second body portion are positioned between the second rotating element and the single pivot pin.

Claims20

Dependent claims

A method of operating a medical device comprising a first jaw portion and a second jaw portion, the method comprising:

rotating a first rotating element about a rotational axis of the first rotating element to cause rotation of a second rotating element about a rotational axis of the second rotating element;
and
restricting a range of rotational motion of the first and second jaw portions, wherein the range of rotational motion is restricted by an elongate slot of a first body portion and a pin affixed to a second body portion, wherein the first jaw portion is coupled to the second jaw portion by the first body portion and the second body portion,
wherein the rotation of the second rotating element causes translation of a first actuation element along the rotational axis of the second rotating element,
wherein the translation of the first actuation element causes pivotal motion of the first jaw portion towards the second jaw portion, wherein the pivotal motion occurs about a single pivot pin, and
wherein the elongate slot of the first body portion and the pin affixed to the second body portion are positioned between the second rotating element and the single pivot pin.

A method of operating a medical device comprising a first jaw portion and a second jaw portion, the method comprising:

rotating a threaded rotating element about a rotational axis of the threaded rotating element, wherein the threaded rotating element is coupled to a first body portion of the medical device by a first threaded coupling element, and wherein the threaded rotating element is coupled to a second body portion of the medical device by a second threaded coupling element;
and
restricting a range of rotational motion of the first and second jaw portions, wherein the range of rotational motion is restricted by an elongate slot of the first body portion and a pin affixed to the second body portion, wherein the first jaw portion is coupled to the second jaw portion by the first body portion and the second body portion,
wherein the rotating the threaded rotating element about the rotational axis of the threaded rotating element translates the first threaded coupling element that is rotatably disposed within a channel of the first body portion,
wherein the translation of the first threaded coupling element pivotally actuates the first jaw portion towards the second jaw portion, wherein the pivotally actuating the first jaw portion towards the second jaw portion includes pivotally actuating the first body portion towards the second body portion about a single pivot pin, and
wherein the elongate slot of the first body portion and the pin affixed to the second body portion are positioned between the threaded rotating element and the single pivot pin.
