Magnetic scope manipulator
Devices and methods are provided for manipulating scoping devices, surgical tools, and/or tissue. An exemplary system for manipulating a scoping device can include a scoping device having a working channel, a tether extending through the working channel, and an internal coupling member attached to the tether and positioned adjacent to a distal end of the scoping device. The internal coupling member can be magnetically coupled to an external coupling member. An exemplary method for manipulating a scoping device can include inserting at least a portion of a scoping device into a body cavity and positioning an external coupling member proximate to an external surface of tissue such that the external coupling member magnetically couples through the tissue to an internal coupling member disposed within the body cavity and attached to a tether passed through at least one working channel of the scoping device.
1. A system for manipulating a scoping device, comprising:
a scoping device having at least one working channel extending therethrough, the at least one working channel having a proximal end and a distal end;
a tether extending through the at least one working channel of the scoping device; and
an internal coupling member attached to a distal end of the tether and positionable adjacent to a distal end of the scoping device, the internal coupling member configured to be magnetically coupled to an external coupling member and having a working channel extending from a proximal end of the internal coupling member to a distal end of the internal coupling member,
wherein, when the internal coupling member positioned adjacent to the distal end of the scoping device, a longitudinal axis of the working channel of the internal coupling member is parallel to a longitudinal axis of the at least one working channel of the scoping device such that a tool can be inserted into the proximal end of the at least one working channel of the scoping device and advanced to extend out of a distal end of the working channel of the internal coupling member; and
wherein the scoping device includes at least one magnetically-attracted collar disposed therearound and positioned proximal to the distal end of the scoping device.
2. The system of claim 1 , wherein the internal coupling member comprises a magnet.
3. The system of claim 1 , wherein the scoping device is an endoscope.
4. The system of claim 1 , wherein the internal coupling member has a generally tubular shape.
5. The system of claim 1 , wherein the internal coupling member includes a feature formed thereon configured to be grasped by a surgical tool.
6. The system of claim 1 , wherein the internal coupling member is removably attached to the distal end of the scoping device.
7. The system of claim 1 , wherein the internal coupling member includes at least one magnet selected from the group consisting of an electromagnet, a permanent magnet, and a non-permanent magnet.
8. The system of claim 1 , further comprising an external coupling member.
9. The system of claim 8 , wherein the external coupling member includes at least one magnet selected from the group consisting of an electromagnet, a permanent magnet, and a non-permanent magnet.
10. The system of claim 1 , wherein the at least one collar is slidably disposed around the scoping device.
11. The system of claim 1 , wherein the at least one collar is formed of a flexible mesh.
12. The system of claim 1 , wherein the collar includes at least one magnet selected from the group consisting of an electromagnet, a permanent magnet, and a non-permanent magnet.
