Tenaculum stabilizer device
View Patent ↗An apparatus for treating tissue, comprising a sheath defining a lumen sized and shaped to receive a treatment device therein, a guide member coupled to the sheath and extending a predetermined distance substantially parallel to a longitudinal axis of the sheath, and a stabilizer element for engaging an anchoring device coupled to tissue to stabilize the sheath and the treatment device, the stabilizing element being movably coupled to the guide member for movement therealong substantially parallel to the longitudinal axis of the sheath wherein, when in a proximal-most position, the stabilizer element is located proximally of a proximal end of the guide member.
1. An apparatus for treating tissue, comprising:
a sheath defining a lumen sized and shaped to receive a treatment device therein;
a guide member comprising a handle coupled to the sheath, a stabilizer track coupled to the handle, and an elongated rail slidably received over the track, the guide member extending a predetermined distance substantially parallel to a longitudinal axis of the sheath; and
a stabilizer element for engaging an anchoring device coupled to tissue to stabilize the sheath and the treatment device, the stabilizer element being coupled to a proximal portion of the elongated rail, the stabilizer element being movable along the track substantially parallel to the longitudinal axis of the sheath wherein, when in a proximal-most position, a distal end of the stabilizer element is located proximally of a proximal end of the handle.
2. The apparatus of claim 1 , wherein the stabilizer track extends distally of a tenaculum engaging surface of the stabilizer element by a distance selected so that, when the stabilizer element is in the proximal-most position, the stabilizer track maintains a portion of its length mounted on the handle sufficient so that force applied from a tenaculum to the stabilizer element prevents undesired movement of the sheath.
3. The apparatus of claim 1 , further comprising:
a positive stop limiting relative movement of the stabilizer element and the sheath within a predetermined range.
4. The apparatus of claim 3 , wherein the positive stop comprises a first surface discontinuity on the elongated rail with a corresponding surface discontinuity on the stabilizer track.
5. The apparatus of claim 4 , wherein the first surface discontinuity includes an abutting surface projecting away from the stabilizer element toward the sheath.
6. The apparatus of claim 1 , wherein the stabilizer element is one of fin shaped, hook shaped and groove shaped.
7. The apparatus of claim 1 , wherein the stabilizer element is shaped to engage one of a cross bar, a finger loop and a body of a tenaculum.
8. The apparatus of claim 1 , further comprising a low friction coating on at least one of the elongated rail and the stabilizer track.
9. The apparatus of claim 1 , wherein the stabilizer element is formed of one of ABS, polyethylene and delrin.
10. The apparatus of claim 1 , wherein the guide member is integrally formed with the sheath.
11. The apparatus of claim 1 , wherein the stabilizer element is lockable in a plurality of positions along the guide member to define a corresponding plurality of positions of the stabilizer element relative to the sheath.
12. The apparatus of claim 1 , wherein the guide member and the stabilizer element are dimensioned so that, when the sheath is in a desired position within a body, the stabilizer element may be positioned along the guide member to provide a desired tension to a portion of a tenaculum.
13. The apparatus of claim 1 , further comprising a telescoping scope adapter coupled to the handle at a proximal end of the sheath, the handle comprising a depressible button selectively engaging the scope adapter with a respectively formed locking hole in the guide member.
14. The apparatus of claim 13 , further comprising a locking ring formed around an inner lumen of the scope adapter to prevent fluid leakage therepast.
