Abstract
Apparatus used for manipulation of a gripped element employed in surgery, which includes two elongated arms, each of which has a distal first zone, a second zone or zones rearward of the distal first zones, and a handle from which the arms extend forwardly, the arms extending so that the first distal zones are yieldably urged toward one another by the arms to hold the gripped element therebetween, at least one of the arm second zones configured to move relative to the other arm in response to controllable force exertion between and along the arms, thereby to cause the first zones to relatively separate, enabling gripping or release of the element.
Claims35
Apparatus used for manipulation of a gripped element employed in surgery, which includes in combination:
- a) two elongated lever arms, each of which has a distal first zone, and a second zone or zones rearward of said distal first zone, and a handle from which the arms extend forwardly, the arms urged toward one another,
- b) said arms being biased such that said first distal zones are yieldably urged toward one another to hold the gripped element therebetween,
- c) at least one of said arm second zones configured to move away from the other arm in response to controllable force exertion between said second zones of the arms, thereby to cause said first zones to relatively separate, enabling gripping or release of said element, and
- d) a Pusher located between said arm second zone or zones for exerting said controllable force, in response to being pushed by a user, and a spring located between said arms for biasing said pusher to relieve said controllable force.
The method of manipulating an element to be gripped for use in surgery, which includes
- a) providing two elongated lever arms, each of which has distal first zone, and a second zone or zones rearward of said distal first zone, and providing a handle from which said arms extend forwardly, and are urged toward one another,
- b) said arms being biased such that said first distal zones are yieldably urged toward one another to hold the gripped element therebetween,
- c) at least one of said arm second zones configured to move away from the other arm in response to controllable force exertion between said second zone or zones of the arms,
- d) and exerting controlled force between the arms to cause said at least one arm to move relative to the other arm for enabling gripping or release of said element by said first distal zone,
- e) there being a pusher located between said arm second zone or zones for exerting said controllable force, in response to being pushed by a user, and a spring located between said arms for biasing said pusher to relieve said controllable force.
