Abstract
The methods and apparatus of this invention provide instrumentation for clamping and securing instruments to support members. Specific embodiments of the invention are particularly useful as devices and methods for use during surgical procedures, such as implantation procedures to properly implant a prosthesis.
Claims12
A clamp for securing an instrument to a support member, the clamp comprising:
- (a) a main body comprising (i) a top portion, (ii) a middle portion, and (iii) a base portion, wherein the porlions are separated by at least two channels, the clamp further comprising (iv) a cooperating interface adapted to cooperate with at least a portion of the support member;
- (b) an instrument holder supported by the main body and defining a receiving aperture adapted to receive and secure an instrument with respect to the clamp, wherein the aperture is defined to have a receiving axis that is generally orthogonal to a long axis of the instrument holder;
- (c) a tightening member supported by the main body and adapted to extend through the main body and in use to at least partially compress the at least two channels of the main body such that an instrument in the instrument holder is secured in at least partial non-rotational and at least partial non-translational stability with respect to the main body and the cooperating interface secures the clamp to at least a portion of the support member.
A system for positioning and stabilizing surgical instruments, comprising:
- (a) a support member for positioning over a surgical site;
- (b) a clamp for securing instruments to the support member, wherein the clamp comprises:
- (i) a main body comprising a top portion, a middle portion, and a base portion, wherein the portions are separated by at least two channels, the clamp further comprising a cooperating interface adapted to cooperate with at least a portion of the support member;
- (ii) an instrument holder supported by the main body and defining a receiving aperture adapted to receive and secure an instrument with respect to the clamp, wherein the receiving aperture is defined to have a receiving axis that is generally offset to a long axis of the instrument holder;
- (iii) a tightening member supported by the main body and adapted to extend through the main body and in use to at least partially compress the at least two channels of the main body such that an instrument in the instrument holder is secured in at least partial non-rotational and at least partial non-translational stability with respect to the main body and the cooperating interface secures the clamp to at least a portion of the support member;
- and
- (c) an instrument for being received by the clamp.

A method for clamping an instrument to a support member, comprising:
- (a) providing a support member;
- (b) providing an instrument;
- (c) providing a clamp, comprising:
- (i) a main body comprising a top portion, a middle portion, and a base portion, wherein the portions are separated by at least two channels, the clamp further comprising a cooperating interface adapted to cooperate with at least a portion of the support member;
- (ii) an instrument holder supported by the main body and defining a receiving aperture adapted to receive and secure an instrument with respect to the clamp, wherein the receiving aperture is defined to have a receiving axis that is generally orthogonal to a long axis of the instrument holder;
- (iii) a tightening member supported by the main body and adapted to extend through the main body and in use to at least partially compress the at least two channels of the main body such that the instrument holder is secured in at least partial non-rotational and at least partial non-translational stability with respect to the main body and the cooperating interface secures the clamp to at least a portion of the support member;
- (d) inserting the instrument into the instrument holder;
- (e) positioning the cooperating interface such that it cooperates with at least a portion of the support member;
- and
- (f) tightening the tightening member to (1) secure the instrument in at least partial non-rotational and at least partial non-translational movement with respect to the clamp and (2) secure the clamp in at least partial non-rotational and at least partial non-translational movement with respect to the support member.
7 more elements
A clamp system comprising:
- an integrally formed main body defining a top portion, a middle portion, and a base portion wherein the top and middle portions are at least partially divided by a first channel and the middle and base portions are at least partially divided by a second channel;
- an instrument aperture defined by the top portion and the middle portion;
- a cooperating portion defined by the middle and base portions and adapted to cooperate with a support member;
- a throughpin adapted for insertion through the top, middle, and base portions such that upon tightening the throughpin, the first and second channels are at least partially compressed;
- and
- an instrument holder extending into the instrument aperture, wherein the instrument holder comprises a slot such that upon tightening the throughpin, the slot is at least partially compressed.

A method for clamping an instrument to a support member, the method comprising:
- providing a support member;
- providing an instrument;
- providing a clamp comprising:
- an integrally formed main body defining a top portion, a middle portion, and a base portion wherein the top and middle portions are at least partially divided by a first channel and the middle and base portions are at least partially divided by a second channel;
- an instrument aperture defined by the top portion and the middle portion;
- a cooperating portion defined by the middle and base portions and adapted to cooperate with a support member;
- and
- a throughpin adapted for insertion through the top, middle, and base portions such that upon tightening the throughpin, the first and second channels are at least partially compressed;
