Abstract
A medical system includes an insertion device and an insertion device handle. The insertion device handle has a proximal portion and a distal portion, with a delivery shaft extending from the distal portion. The medical system also includes a medical device, including a spool and a medical device handle. The medical device handle has a central opening, and the spool and the medical device handle are rotatably movable to one another and form a channel. The medical system includes an adapter couplable to a portion of the insertion device handle, and the adaptor includes a post element to be received within the central opening of the medical device handle.
Claims19
A medical system comprising:
- an insertion device including an insertion device handle having a proximal portion and a distal portion and a delivery shaft extending from the distal portion;
- a medical device including a spool, a medical device handle with a central opening, and a control knob movable relative to the spool and including at least one slot, wherein the spool and the medical device handle are rotatably movable to one another and form a channel, wherein the spool includes a plurality of spool teeth positioned on the spool facing the medical device handle, and wherein the medical device handle includes a plurality of handle teeth positioned on the medical device handle facing the spool;
- and
- an adaptor coupleable to a portion of the insertion device handle, wherein the adaptor includes a post element to be received within the central opening of the medical device handle.
A medical device comprising:
- a rotatable spool element including a plurality of spool teeth;
- a handle element including a plurality of handle teeth, wherein the handle element is circular;
- a rotatable control knob movable relative to the spool element;
- and
- a coiled element including a sheath surrounding at least a portion of a drive wire, wherein a distal end of the drive wire is coupled to an end effector,
- wherein the spool element or the handle element form a channel to house at least a portion of the coiled element,
- wherein the plurality of spool teeth are positioned in a circle on the spool element facing the handle element,
- wherein the plurality of handle teeth are positioned in a circle on a circumference of the handle element facing the spool element, and
- wherein the medical device is configured to receive a biasing member between the spool teeth and the handle teeth.
A method of operating a medical system, comprising:
- inserting an insertion device into a patient, wherein the insertion device includes a delivery shaft, a deflection mechanism, and at least one port;
- coupling a medical device to the insertion device via an adaptor, wherein the medical device includes at least a spool, a handle, a control knob movable relative to the spool, and a coiled element at least partially stored between or within the spool and the handle, wherein the spool includes a plurality of spool teeth positioned on the spool facing the handle, wherein the handle includes a plurality of handle teeth positioned on the handle facing the spool, and wherein coupling the medical device via the adaptor rotatably locks the handle in place;
- delivering the coiled element through the at least one port by rotating the spool.
