Claim:
1. A surgical tool handle, comprising: a) an elongate body extending from a proximal body portion to a distal body portion; b) a body lumen at least partially residing within the elongate body, wherein the body lumen extends from a proximal body lumen end residing in the proximal body portion to a distal body lumen portion having a distal body lumen end residing in the distal body portion; c) a coil spring positioned within the distal body lumen portion, wherein the coil spring has a coil lumen extending along a longitudinal axis from a proximal coil end to a distal coil end, the coil lumen having a first diameter perpendicular to the longitudinal axis with the coil spring in a relaxed state, and wherein the distal coil end is connected to the elongate body; and d) an actuator extending through the body lumen, the actuator comprising spaced apart proximal and distal actuator ends, wherein the distal actuator end is received inside the proximal coil end to thereby connect the actuator to the coil spring while leaving open a remainder of the coil spring lumen extending distally from the distal actuator end to the distal coil end, and wherein the proximal actuator end is accessible from outside the body adjacent to the proximal body portion, e) wherein rotation of the actuator in a first direction causes rotation of the coil spring to enlarge the coil lumen from the relaxed state having the first diameter to a second diameter of a size sufficient to receive the connection member of a surgical tool through the distal coil open end and into the coil lumen, and wherein rotation of the actuator in a second, opposite direction causes rotation of the coil spring to constrict the coil lumen from the second diameter to a lesser, third diameter perpendicular to the longitudinal axis that is sufficient to securely contact the connection member and thus secure the surgical tool to the surgical tool handle.
