Abstract
Abstract A surgical instrument to aid in maneuvering a slideable member along a rod or other base member. The instrument has a distal tip which straddles the slideable member to provide for longitudinal movement of the slideable member in either longitudinal direction. The instrument also allows downward force to be applied to the slideable member. The instrument also may be used to assist in introducing the slideable member into an opening of another device.

Claim 9
Independent Claim
154 words
A method of utilizing a surgical instrument in conjunction with a slideable member located along an elongated rod and wherein the instrument includes a distal tip and an elongated handle extending therefrom, the tip including first and second extending members spaced apart from each other and rigidly connected by an interconnecting portion therebetween, thus providing a cavity having fixed spacing between the first and second extending members, the cavity being open on at least one side and being adapted for accepting a portion of the slideable member therein for straddling the slideable member between the first and second extending members, the method including the following steps: (a) straddling the slideable member in the cavity between the first and second extending members of the instrument; and (b) applying longitudinal force to the instrument to slide both the whole instrument and the straddled slideable member longitudinally along the rod to the desired location along the rod.
Claim 10
Independent Claim
154 words
A method of utilizing a surgical instrument in conjunction with a slideable member located along an elongated rod and wherein the instrument includes a distal tip and an elongated handle extending therefrom, the tip including first and second extending members spaced apart from each other and rigidly connected by an interconnecting portion therebetween, thus providing a cavity having fixed spacing between the first and second extending members, the cavity being open on at least one side and being adapted for accepting a portion of the slideable member therein for straddling the slideable member between the first and second extending members, the method including the following steps: (a) straddling the slideable member in the cavity between the first and second extending members of the instrument; and (b) applying longitudinal force to the instrument to slide both the whole instrument and the straddled slideable member longitudinally along the rod to the desired location along the rod.
Claim 11
Independent Claim
213 words
A method of utilizing a surgical instrument in conjunction with a slideable member located along an elongated rod wherein the slideable member is adapted for being inserted through an opening in an open-back member, and wherein the instrument includes a distal tip and an elongated handle extending therefrom, the tip including first and second extending members spaced apart from each other and rigidly connected by an interconnecting portion therebetween, thus providing a cavity having fixed spacing between the first and second extending members, the cavity being open on at least one side and being adapted for accepting a portion of the slideable member therein for straddling the slideable member between the first and second extending members, the method including the following steps: (a) positioning the elongated rod over the opening to the open-back member; (b) straddling the slideable member in the cavity between the first and second extending members of the instrument; (c) applying longitudinal force to the instrument to slide both the whole instrument and the straddled slideable member in the desired longitudinal direction along the rod to the desired location above the opening of the open-back member; and (d) pushing down on the instrument to cause the slideable member to pass through the opening of the open-back member for locating therein.

The method of claim 7 wherein the slideable member includes a tapered portion for mating location within a corresponding tapered cavity in the open-back member, the method further including, applying longitudinal force to the instrument and thus to the slideable member once it is located in the open-back member to cause the taper on the slideable member to slide further into and tighten against the taper on the open-back member, and thus securely seating the slideable member in place.
Claim 14
Dependent Claim
50 words
The method of claim 8 wherein the slideable member includes a threaded portion with a threadedly engaged nut, the method further including the step of threading the nut up to the open-back member to more securely locate the slideable member and open-back member in the desired position on the rod.
Claim 15
Independent Claim
170 words
