Method, apparatus, and system for facilitating bending of an instrument in a surgical or medical robotic environment
A method, apparatus, and system for facilitating bending of an instrument in a surgical or medical robotic environment are provided. In one aspect, a surgical system includes an instrument comprising an end effector, the instrument capable of articulation via a bending section. The bending section includes a body including a first strut and a second strut, and a channel formed through the body. The first strut and the second strut form a gap therebetween, wherein the gap is in communication with the channel formed through the body.
1. A surgical system comprising:
an instrument comprising an end effector and being capable of articulation via a bending section that comprises:
a body including a first leaf and a second leaf; and
a channel formed through the body,
wherein:
the first leaf and the second leaf form a gap therebetween,
at least one of the first leaf and the second leaf has a globular form at a top portion and tapers towards a bottom portion,
the gap has a globular form at a bottom of the gap and tapers towards a top of the gap,
the gap is in communication with the channel formed through the body,
the channel comprises an open region that permits lateral insertion of ancillary components into the channel; and
the open region comprises two opposing fingers.
2. The system of claim 1 , wherein the gap is formed through an outer surface of the body.
3. The system of claim 1 , wherein a size of the gap between the first leaf and the second leaf is capable of changing.
4. The system of claim 1 , wherein the channel is non-cylindrical.
5. The system of claim 1 , wherein the channel receives an articulation wire.
6. The system of claim 5 , wherein the channel further receives an ancillary component of the end effector.
7. The system of claim 6 , wherein the ancillary component comprises fibers or electrical wires.
8. The system of claim 1 , wherein the end effector comprises a pair of tines.
9. The system of claim 1 , wherein the end effector is passable through a working channel such that it is interchangeable.
10. The system of claim 1 , wherein the end effector comprises forceps, scissors, a laser, a camera, a cautery tool, or a needle.
11. The system of claim 1 , wherein the two opposing fingers are separated by a gap when the body is in an unarticulated state.
12. The system of claim 11 , wherein the two opposing fingers are configured to move toward one another when the body is articulated.
13. A surgical system comprising:
an instrument comprising an end effector and being configured to articulate via a bending section that comprises a body including a first leaf and a second leaf;
a gap formed through an outer surface of the body, wherein at least one of the first and second leaf having a globular form at a top portion and tapering towards a bottom portion, wherein the gap having a globular form at a bottom of the gap and tapering towards a top of the gap; and
a channel formed through the body that is in communication with the gap,
wherein:
the channel comprises an open region that permits lateral insertion of ancillary components into the channel; and
the open region comprises two opposing fingers.
14. The system of claim 13 , wherein the channel is non-cylindrical.
15. The system of claim 13 , wherein the gap is formed between the first leaf and the second leaf.
16. The system of claim 15 , wherein a size of the gap between the first leaf and the second leaf is capable of changing.
