Medical device actuation systems and related methods of use

摘要

A medical system including an endoscope having a proximal end, a distal end, and a lumen extending therebetween is disclosed. The endoscope includes a port configured to provide access to the lumen. In addition, the system may include an actuation member slidably disposed through the lumen such that a proximal end of the actuation member extends through the port, and a distal end of the actuation member is operably coupled to an end-effector. The system may further include an actuation handle removably secured to the actuation member. In one embodiment, a portion of the end-effector has dimensions larger than a maximum dimension of the lumen.

主权项

1. A medical system, comprising:
an endoscope having a proximal end, a distal end, and a lumen extending therebetween, the endoscope further including a port configured to provide access to the lumen; an actuation member disposed within at least a portion of the lumen, wherein a proximal end of the actuation member extends through the port, a distal end of the actuation member is operably coupled to an end-effector, and the actuation member is uniform from the proximal end of the actuation member to the end-effector, and wherein the end-effector comprises (a) a first jaw moveably coupled directly to the distal end of the actuation member and (b) a second jaw, wherein the end-effector is disposed outside of the distal end of the lumen, and wherein a proximal end of the first jaw and a proximal end of the second jaw remain uncovered by any component of the medical system when the end-effector is in an open configuration, when the end-effector is in a closed configuration, and during insertion of the end-effector within a patient; and a handle disposed adjacent the port and configured to be removably secured to the actuation member; wherein at least a portion of the end-effector has a dimension larger than a maximum dimension of the lumen.
