Clip-holder instrument for clipping blood vessels

Claim 1

A clip-holder instrument for clipping blood vessels comprising, in combination: (a) a grip handle, said grip handle having an upper portion and a bottom portion, said bottom portion being a pistol butt-shaped member; (b) operating means for operating said grip handle, said operating means being assembled on said upper portion of said grip handle; (c) a clip; (d) a rod and tube assembly means for clamping and releasing said clip, having a rod, said rod having a front portion and a rear portion, said rear portion passing through said upper portion of said grip handle, said front portion forming a hooking means for hooking said clip, said rod being freely rotatable and having an operation knob joined on said rear portion of said rod opposite said grip handle, said operation knob controlling the rotation of said rod; and (e) lever means and a retraction member for operating said rod and tube assembly, said lever means having a power arm, said power arm being a trigger-shaped member, said lever means extending from said upper portion of said grip handle and being connected to said retraction means.

Claim 7

A method for clipping blood vessels through the utilization of a clip-holder instrument and a clip, which comprises: (a) gripping said instrument in the middle, ring and little fingers of the hand, said instrument having a rod and a lever means thereon, said lever means having a power arm, said rod having a terminal, said terminal including a hooking means for hooking a clip, said rod having a tube displaceable thereon, said tube being displaceable from an inward position to an outward position and having a retraction member joined thereto, said lever means being connected to said retraction means, said retraction member being retractable, said rod having an expansion spring therearound for forwardly biasing said retraction member and said tube, said expansion spring having a tension thereon; (b) pressing said power arm of said lever means, thereby retracting said retraction member and said tube joined thereto against said tension of said expansion spring; (c) uncovering said hooking means of said terminal of said rod; (d) hooking said clip to said hooking means, said clip having branches and prehensile branches and being capable of an open configuration and a closed configuration; (e) releasing said power arm of said lever means, thereby displacing said member and said tube to an outward position; (f) compressing elastically said branches of said clip thereby permitting said clip to remain in an open position; (g) maintaining said clip secure at the end of said instrument by means of said hooking means; (h) placing said clip at the desired placement position; (i) pressing said power arm of said lever means thereby decompressing said branches of said clip and joining said prehensile branches of said clip to enable said prehensile branches to close on said blood vessel; (j) unhooking said hooking means from said clip; and, (k) withdrawing said instrument from said blood vessel leaving said clip in position on said blood vessel.

Claim 8

A method for clipping blood vessels through the utilization of a clip-holder instrument and a clip, which comprises: (a) gripping said instrument in the middle, ring and little fingers of the hand, said instrument having a rod and a lever means thereon, said lever means having a power arm, said rod having a terminal, said terminal including a hooking means for hooking a clip, said rod having a tube displaceable thereon, said tube being displaceable from an inward position to an outward position and having a retraction member joined thereto, said lever means being connected to said retraction means, said retraction member being retractable, said rod having an expansion spring therearound for forwardly biasing said retraction member and said tube, said expansion spring having a tension thereon; (b) pressing said power arm of said lever means, thereby retracting said retraction member and said tube joined thereto against said tension of said expansion spring; (c) uncovering said hooking means of said terminal of said rod; (d) hooking said clip to said hooking means, said clip having branches and prehensile branches and being capable of an open configuration and a closed configuration; (e) releasing said power arm of said lever means, thereby displacing said member and said tube to an outward position; (f) compressing elastically said branches of said clip thereby permitting said clip to remain in an open position; (g) maintaining said clip secure at the end of said instrument by means of said hooking means; (h) placing said clip at the desired placement position; (i) pressing said power arm of said lever means thereby decompressing said branches of said clip and joining said prehensile branches of said clip to enable said prehensile branches to close on said blood vessel; (j) unhooking said hooking means from said clip; and, (k) withdrawing said instrument from said blood vessel leaving said clip in position on said blood vessel.
