Abstract
A device (100) for clamping cables or wires or other elongate members used in surgical fastening procedures includes a generally cylindrical housing (110) having a bore (112) for receiving a cable. A saddle member (140) is movably mounted with respect to the housing (110) and includes a saddle jaw (146) that may selectively be moved into engagement with a cable (10) disposed in the bore. A cam lever (160) having a cam surface (164) engages a cam support surface (122) on the housing (110) for actuating the saddle member (140) and thereby selectively clamping the cable (10). The saddle jaw (146) cooperates with a housing jaw (124) on the housing (110) for redirecting the cable (10) into an undulating path when the cam lever (160) is moved to a clamping position. The cam lever (160) is provided with multiple facets (164A and 164B) dimensioned to provide optimum clamping force to different sized cables. The facets (164A and 164B) also provide a positive tactile indication to a user that the cam lever (160) is in one of multiple clamping positions.
Claims
1. A clamp for clamping elongate members of varying lateral dimension, the clamp comprising: a housing for receiving the elongate member, the housing having a bore extending therethrough; a saddle member movably mounted with respect to the housing; a cam lever cooperating with the saddle member and having a cam surface for moving the saddle member relative to the housing; and an engaging surface associated with the saddle member for engaging a periphery of the elongate member.
2. The clamp of claim 1 , wherein the cam surface formed on the cam lever has at least two facets.
3. The cable clamp of claim 1, wherein the engaging surface is formed as an undulating surface.
4. The clamp of claim 1 , wherein the cam lever is pivotably attached to the saddle member.
5. The clamp of claim 1 , wherein the cam lever includes an arm for permitting a user to actuate the saddle member.
6. The clamp of claim 1 , wherein the cam surface is adapted to engage a surface on the housing.
