Abstract

A rotating and tip deflecting handle for spring guides, having a generally cylindrical handle portion, including a hand grip, an intermediate assembly and a carriage slidable with respect to the handle portion, means in each of said relatively slidable portions for engaging, respectively, the guide wire or the core wire, and the parts of said portions in which said engaging means are located being rotatable with respect to said hand grip. Modifications of the handle design adapt it for use with the slightly differing spring guides of various manufacturers.

Claims

1. A handle for a flexible, elongated controllable tip spring guide having a tubular guide body and a core wire projecting from the proximal end of said guide body, said handle comrising:

a hand grip located at a first, proximal end of the handle, said hand grip having circumferential and axial dimensions such that said hand grip can be held substantially within the palm of the hand of an operator;

an intermediate assembly rotationally and non-slidably mounted in a generally coaxial relationship with the hand grip, the intermediate assembly including a core having at a first, proximal end thereof a cylindrical end portion rotatably engaged in the distal end of the hand grip, the core further having a middle block portion and a distal rod portion coaxial with the cylindrical end portion, the distal rod portion extending axially of the hand grip, the rod portion being longitudinally grooved, said block portion having a radially disposed hole in the plane of said groove, and said hole being connected to said groove by a slit narrower than the diameter of said hole whereby a lug on the end of one of said guide body and a core wire can be retained within said hole with the core wire passing through said slit and said groove;

means on the intermediate assembly for retaining the spring guide along the axis of said handle such that the distal end of said spring guide extends beyond the distal end of the rod portion of the core;

means mounted on said intermediate assembly for rotationally positioning said intermediate assembly; and

, a slidable carriage slidably and non-rotationally mounted on the intermediate assembly so as to permit axial positioning of said carriage on said assembly, said slidable carriage having means for engaging the other one of said guide body and core wire.

2. A handle according to claim 1 wherein at least one of said guide body and wire engaging means includes a radially open slot having wider and narrower portions.

3. A handle according to claim 1 which includes, at its distal end, an adjuster element movable axially of the handle and provided with means for securement in different axially adjusted positions.

4. A handle according to claim 1 wherein the means for positioning the intermediate assembly comprises a wheel-like member axially spaced from the hand grip so as to permit rotation of the wheel-like member by the thumb and forefinger of said operator.

5. A handle according to claim 1 wherein the slidable carriage is non-rotatably mounted on the distal rod portion of the core.

6. A handle according to claim 5 wherein the slidable carriage is provided with a longitudinal slot in register with the groove in the rod pOrtion, said slot terminating distally adjacent a slitted abutment adapted to bear against a lug on the proximal end of the tubular guide body.

7. A handle according to claim 6 which includes an adjuster element slidable engaged with a distal end portion of the carriage and provided with means for securement in different axially adjusted positions.

8. A handle assembly according to claim 1 and including means on the intermediate assembly for engaging one of said guide body and core wire.

9. A handle for a flexible, elongated controllable tip spring guide having a tubular guide body and a core wire projecting from the proximal end of said guide body, said handle comprising:

a hand grip located at a first, proximal end of the handle, said hand grip having circumferential and axial dimensions such that said hand grip can be held substantially within the palm of the hand of an operator;

an intermediate assembly including a mounting plug rotationally and non-slidably mounted at a first, proximal end in a generally coaxial relationship at the distal end of said hand grip, the intermediate assembly further including a rod having a first, proximal end fixed in the second, distal end of said plug eccentrically thereof, the second, distal end of said rod extending axially beyond said plug and having mounted on said distal end a guide body mounting block, said guide body mounting block having means for providing a rigid attachment to said rod;

means on the intermediate assembly for engaging one of said guide body and core wire;

means on the intermediate assembly for retaining the spring guide along the axis of said handle such that the distal end of said spring guide extends beyond the distal end of said intermediate member;

means mounted on the intermediate assembly for rotationally positioning said intermediate assembly; and

, a slidable carriage slidably and non-rotatably mounted on the rod of the intermediate assembly between said plug and said guide body mounting block so as to permit axial positioning of said carriage on said assembly, the slidable carriage having means for engaging the other one of said guide body and core wire.

10. A handle according to claim 9 wherein the guide body mounting block is traversed from end to end by a slot.

11. A handle according to claim 10 wherein said slot is formed with an enlarged chamber to receive the proximal end fitting of a guide body, said chamber being bounded proximally and distally by narrowed parts of said slot adapted to restrain said fitting from axial movement out of said chamber.

12. A handle according to claim 9 which includes a trigger fixed in said carriage and projecting therefrom, said trigger being shaped and positioned for convenient operation by the operator'"'"''"'"'s finger to slide the carriage axially toward or away from the hand grip.

13. A handle according to claim 9 in which the guide body mounting block is formed with a distally extending portion, said adjuster element being provided with means for securement in different axially adjusted positions.

14. A handle according to claim 9 wherein the means for positioning the intermediate assembly comprises a wheel-like member axially spaced from the hand grip so as to permit rotation of the wheel-like member by the thumb and forefinger of an operator.
