Crimp Pliers
A device for securing cable around a bone comprises first and second handles pivotally coupled to one another and a first distal member a proximal end of which is pivotally coupled to a distal end of the first handle, the first distal member including a first crimp engaging protrusion in combination with a second distal member a proximal end of which is pivotally coupled to a distal end of the second handle, the second distal member including a second crimp engaging protrusion, and a depth level including an abutting surface, the first and second distal members being pivotally coupled to one another so that, when the first and second handles are drawn toward one another, the proximal ends of the first and second distal members are moved apart from one another, drawing the first and second protrusions toward one another to compress a crimp located therebetween.
1 . A device for securing, cable around a bone, comprising:
first and second handles pivotally coupled to one another;
a first distal member a proximal end of which is pivotally coupled to a distal end of the first handle, the first distal member including a first crimp engaging protrusion extending away from a ventral surface thereof at a distal end thereof;
a second distal member a proximal end of which is pivotally coupled to a distal end of the second handle, the second distal member including a second crimp engaging protrusion extending away from a ventral surface thereof at a distal end thereof; and
a depth level including an abutting surface, contact between the abutting surface and a depth measuring tube extending over a portion of a cable extending proximally from a crimp, indicating to a user that the first and second protrusions are located on opposite sides of the crimp, the first and second distal members being pivotally coupled to one another so that, when the first and second handles are drawn toward one another, the proximal ends of the first and second distal members are moved apart from one another, drawing the first and second protrusions toward one another to compress a crimp located therebetween.
2 . The device of claim 1 , further comprising a lock mechanism which, when engaged, prevents relative movement between the first and second protrusions.
3 . The device of claim 2 , wherein the lock mechanism includes a bar pivotally connected to one of the first and second handles and releasably coupled to the other of the first and second handles.
4 . The device of claim 1 , further comprising a depth level for determining a crimping position.
5 . A system, comprising:
a flexible cable for passing around a fractured bone;
a crimp member coupleable to a first end of the flexible cable and including a lumen extending therethrough, the lumen slidably receiving a second end of the flexible cable, the crimp member being deformable such that when the crimp is deformed around the flexible cable, the flexible cable is fixed around the bone;
a tube including a distal end shaped to the crimp member, the tube having a lumen extending therethrough, the lumen of the tube in communication with the lumen of the crimp such that the second end of the flexible cable is slidable through the lumen of the tube; and
a crimp plier slidable along the tube, including:
a crimping means including an opposed jaw with a ventrally protruding element at distal tip thereof;
an operating handle coupled to the crimping means such that the operating handle and the crimping means move relative to one another; and
a guiding member for guiding the device along the surgical cable, the guiding member including a ventrally protruding element formed proximally of the ventrally protruding elements of the crimping means.
6 . The system of claim 5 , further comprising a tension device for measuring tension in the cable.
7 . The system of claim 5 , wherein the ventrally protruding element of the guiding member accommodates the tube such that the crimp plier slides along the tube.
8 . The system of claim 5 , wherein the tube includes a block element at a proximal end of the tube, the block element maintaining a desired tension in the cable.
9 . The system of claim 8 , wherein the crimp plier further comprises a depth level, the depth level positioned a predetermined distance from the crimping means such that when the block element of the tube abuts the depth level, the crimping means is positioned over the crimp member.
10 . The system of claim 5 , wherein the crimp plier includes a lock mechanism for locking the operating handles.
11 . The system of claim 10 , wherein the lock mechanism includes a releaseable latch.
12 . The system of claim 5 , wherein the cable includes a ball mechanism at the first end thereof for coupling to the crimp member.
13 . A method, comprising the steps of:
passing a flexible cable around a fractured bone;
attaching a first end of the flexible cable to a crimp member and sliding a second end of the flexible member through a lumen of the crimp member and a lumen of a tube, the tube being shaped to the crimp member such that the lumen of the tube is in communication with the lumen of the crimp member;
sliding a crimp plier along the tube to a predetermined position in which a crimping means is positioned over the crimp member; and
crimping the crimp member over the cable such that the cable is fixed around the fractured bone and maintains a desired tension.
14 . The method of claim 13 , wherein sliding the crimp plier includes sliding a guiding member protruding ventrally from the crimp plier over the tube.
15 . The method of claim 13 , wherein sliding the crimp plier along the tube includes sliding the crimp plier until a block element located on a proximal end of the tube abuts a depth level located on the operating handle, indicating that the crimping means is positioned over the crimp member.
16 . The method of claim 13 , further comprising the step of unlatching a lock mechanism of the operating handle.
17 . The method of claim 13 , further comprising the step of actuating the operating handle to activate the crimping means.
18 . The method of claim 13 , further comprising the step of detaching the tube from crimp member.
