Abstract
A grasper for a surgical retractor is provided. The grasper has a grasper body, a push-button activator and a holder to releasably retain a connector head of, for example, a retractor blade. The holder is configured to move from a first position, located at least partially in the opening to provide for selectively retaining the connector head in the opening, to a second position wherein the connector head may be removed. The push-button activator is operably connected to the holder to move the holder from the first position to the second position. In one embodiment the holder is gear driven by the activator.
Claims13
A grasper for a surgical retractor, the grasper comprising:
- a grasper body having a first surface defining an opening to accept a surgical instrument connector head;
- a gear in the grasper body;
- a holder mechanically connected to the gear and configured to move from a first position to a second position, the first position being located at least partially in the opening to provide for retaining the connector head in the opening;
- wherein the holder is rotatably connected to the grasper body and,
- an activator having a gear track engaging the gear to actuate the holder, the activator traversing linearly, and not rotationally wherein the activator is a push-button activator at least partially seated within the grasper body.
A grasper for a surgical retractor, the grasper comprising:
- a grasper body having a first surface defining an opening to accept a surgical instrument connector head;
- a holder rotatably connected to the grasper body and configured to move from a first position to a second position, the holder selectively retaining the connector head in the opening in the first position;
- a push-button activator at least partially seated within the grasper body and operably connected to the holder to move the holder from the first position to the second position, wherein the push-button activator has a longitudinal axis that is transverse to a longitudinal axis of the grasper body, wherein the push-button activator travels linearly and non-rotationally, MD about its longitudinal axis, and wherein the push-button activator moves from a normal position to an activated position to assist in manipulating the holder from the first position to the second position;
- and,
- a spring within the grasper body and engaging the push-button activator to bias the push-button activator to the normal position.
A grasper for a surgical retractor, the grasper comprising:
- a grasper body having a first surface defining an opening to accept a surgical instrument connector head;
- a holder rotatably connected to the grasper body and configured to selectively move from a first position to a second position, the first position being at least partially in the opening;
- a spring-loaded activator transversely extending from and partially seated within the grasper body, and being operably connected to the holder, wherein the spring-loaded activator travels linearly, and not rotationally, about a longitudinal axis of the activator, and wherein movement of the activator manipulates the holder from the first position to the second position.
A grasper for a surgical retractor, the grasper comprising:
- a grasper body having a first surface defining an opening to accept a surgical instrument connector head;
- a holder rotatably connected to the grasper body and configured to move from a first position to a second position, the holder selectively retaining the connector head in the opening in the first position;
- a push-button activator connected to the grasper body and operably connected to the holder to move the holder from the first position, wherein the push-button activator has a longitudinal axis that is transverse to a longitudinal axis of the grasper body, and wherein the push-button activator travels linearly and non-rotationally, about its longitudinal axis to assist in transitioning the holder from the first position;
- and,
- a spring within the grasper body and engaging the push-button activator to bias the push-button activator to a normal position.
