A dermatome for improved cutting of tissue comprises: a blade assembly, including a blade and a blade carrier; a rotational drive assembly; and a housing which engages the blade assembly to constrain the movement of any point on the blade assembly to bidirectional linear movement over a predefined linear range, wherein the engaged blade assembly forms a cover for the housing so that the housing in combination with the engaged blade assembly defines a closed space which surrounds the rotational drive assembly while the blade assembly moves over the predefined linear range. The entire blade assembly may be releasable from the housing, or the blade may be releasable from the blade carrier which remains non-releasably engaged with the housing.

Direct linear drive dermatome

An apparatus and method for loading and unloading of sample tubes contained in sample tube carriers from the buckets of a swing bucket centrifuge wherein the method includes the steps of lifting the buckets off the rotor of the centrifuge, pushing sample tubes contained in sample tube carriers out of the buckets, pushing new sample tubes contained in sample tube carriers into the buckets, and lowering the buckets back on to the rotor of the centrifuge. The buckets are suspended from axially aligned pins which fit into slots on opposite sides of the buckets and include openings in the sides of the buckets to admit sample tubes contained in sample tube carriers. Once the centrifuge rotor has moved a bucket into a defined position, a lifting mechanism raises the bucket from the centrifuge rotor to a position adjacent to a pushing mechanism which can push sample tubes contained in sample tube carriers out of the bucket and can push new sample tubes contained in sample tube carriers into the bucket.

Method and apparatus for locating functional structures of the lower leg during knee implant surgery by determining the location of the weight-bearing axis. The functional center of the hip is located by fixing the acetabulum of the patient, rotating the femur about its head to several locations, measuring changes of position of a reference point on the femur and computing an imaginary sphere having a center corresponding to the location of the functional center of the hip.

An apparatus for aligning a surgical instrument having a connection device attached to the femur in the vicinity of the knee joint at a point chosen to be on the mechanical axis. An adjustable vertical suspension device attached to the femur for counteracting the moment about the hip joint created by the weight of the femur. A vertical tension indicating device attached to the adjustable vertical suspension device.

Apparatus and method for aligning knee prostheses

Apparatus useful in surgery for holding surgical instruments such as retractor blades in a number of different positions required by a surgeon for the performance of a surgical procedure, including an actuation means responsive to a control signal, a signal generating means which enables an operator to generate the control signal and which transmits the control signal to the actuation means, for causing the actuation means to move the surgical instrument.

Powered surgical retractor

Apparatus useful in surgery for holding retractors and other surgical instrumentation in a number of different positions required by a surgeon for the performance of a surgical procedure, including advanced sensing and regulation of retraction pressures and position; and incorporating a force amplification method to drive a locking mechanism in the supporting structure that utilizes a constrained, substantially incompressible, flexible solid material to yield a mechanism that is suitable for clinical use.

Advanced surgical retractor

Apparatus useful in surgery for holding part of a patient's body such as a limb, portion of a limb, extremity organ or tissue in a number of different positions required by a surgeon for the performance of a surgical procedure, and for establishing a sterile barrier between a surgical site and a patient's limb while the limb is being grasped by a limb positioning apparatus.

Apparatus for patient limb positioning

Apparatus useful in surgery for holding a patient's lower limb in a number of different positions required by a surgeon for the performance of a surgical procedure, and for eastablishing a sterile barrier between a surgical site and a patient's lower limb while the limb is being grasped by such positioning apparatus.

Lower limb positioning apparatus and surgical drape

Apparatus useful in surgery for holding part of a patient's body such as a limb, portion of a limb, extremity organ or tissue in a number of different positions required by a surgeon for the performance of a surgical procedure, and for establishing a sterile barrier between a surgical site and a patient's limb or body part while the limb or body part is being grasped by a such positioning apparatus.
