Abstract

A support system including a rail, a lower support, and an instrument support. The lower support is configured to receive a portion of a bronchoscope and to selectively fix the bronchoscope relative to the rail. The instrument support is slidably disposed on the rail and is selectively lockable to the rail. The instrument support is configured to releasably couple to a surgical instrument inserted through the bronchoscope to fix the position of a portion of the surgical instrument relative to the bronchoscope.

Claims

1. A support system comprising:

a rail having upper and lower ends defining a longitudinal axis therebetween;

a lower support configured to receive a portion of a bronchoscope and to selectively fix the bronchoscope relative to the rail; and

an instrument support slidably disposed on the rail and selectively lockable to the rail, the instrument support configured to releasably couple to a surgical instrument inserted through the bronchoscope to fix the position of a portion of the surgical instrument relative to the bronchoscope, the instrument support including a clamp arm collar and a locking arm, the clamp arm collar slidably disposed over the rail, the clamp arm collar having an outer camming surface, the locking arm pivotable about the longitudinal axis to transition the locking arm between an unlocked position and a locked position, the locking arm having a locking cam configured to slide across the camming surface to engage an inner surface of the clamp arm collar with the rail to longitudinally fix the position of the instrument support relative to the rail as the locking arm is pivoted towards the locked position.

2. The support system of claim 1, wherein the instrument support includes a clamp arm having instrument fingers extending from the clamp arm collar, the instrument fingers defining an instrument passage configured to releasably couple to the surgical instrument.

3. The support system of claim 1, wherein in the locked position of the locking arm the instrument support is radially locked relative to the rail.

4. The support system of claim 1, wherein the lower support defines a rail opening configured to receive the lower end of the rail.

5. The support system of claim 4, further comprising a collar positioned within the rail opening including a threaded portion.

6. The support system of claim 5, further comprising a securement member threaded over the threaded portion of the collar to compress the collar over the lower end of the rail to fix the rail to the lower support.

7. The support system of claim 1, wherein the lower support includes a pair of support fingers extending orthogonal relative to the rail, the support fingers defining a support opening therebetween.

8. The support system of claim 7, wherein the support fingers are configured to compress the support opening about the bronchoscope to fix the lower support relative to the bronchoscope.

9. The support system of claim 1, wherein the locking arm includes a locking arm collar disposed over the rail.

10. A surgical system comprising:

a bronchoscope;

an extended working channel extending through the bronchoscope;

an elongated surgical instrument inserted through the extended working channel; and

a support system for supporting the elongated surgical instrument relative to the bronchoscope, the support system including;

a rail having upper and lower ends defining a longitudinal axis therebetween;

a lower support fixed to the lower end of the rail and to the bronchoscope to fix the rail to the bronchoscope; and

an instrument support slidably disposed on the rail and selectively lockable to the rail, the instrument support releasably coupled to a first portion of the elongated surgical instrument to fix the position of the first portion of the elongated surgical instrument relative to the bronchoscope, the instrument support including a clamp arm collar and a locking arm, the clamp arm collar slidably disposed over the rail, the clamp arm collar having an outer camming surface, the locking arm pivotable about the longitudinal axis to transition the locking arm between an unlocked position and a locked position, the locking arm having a locking cam configured to slide across the camming surface to engage an inner surface of the clamp arm collar with the rail to longitudinally fix the position of the instrument support relative to the rail as the locking arm is pivoted towards the locked position.

11. The surgical system of claim 10, wherein a second portion of the elongated surgical instrument is moveable relative to the bronchoscope.

12. The surgical system of claim 11, wherein the second portion of the elongated surgical instrument is fixed to a proximal end of the extended working channel such that the extended working channel is moveable relative to the bronchoscope and the first portion of the elongated surgical instrument.

13. The surgical system of claim 12, wherein the first portion of the elongated surgical instrument includes an ablation probe extending through the second portion of the elongated surgical instrument and the extended working channel.

14. The surgical system of claim 10, wherein the extended working channel includes a telescopic extended working channel handle fixed to the bronchoscope such that when the telescopic extended working channel handle is manipulated, the bronchoscope and the elongated surgical instrument, being fixed to the bronchoscope by the support system, move in concert with the telescopic extended working channel handle.
