Abstract: A retractor system, kit and method of use include a plurality of retractors for use in retracting a wound during a minimally-invasive hip replacement surgery to define an access space to a surgical site is discussed. Each of the retractors comprises a handle portion configured to be held by a user, a curved bend portion distal of the handle portion, and a wound contact portion attached to the curved bend portion. The wound contact portion is configured to contact tissue of the wound when at least a portion of the retractor is inserted through a skin incision that defines the wound. Each retractor also has a distal portion disposed distally of the wound contact portion, wherein the wound contact portion has a generally curved cross-sectional profile perpendicular to its length that is configured to prevent necrosis of the tissue during retraction. In addition, the cross-sectional profile provides an improved line of sight during the surgical procedure.

Abstract: An implant insertion device includes a handle, an insertion rod attached to the handle, and an implant gripper attached to the insertion rod. The implant gripper includes a gripping surface that has a movable pin and a fixed pin. The implant insertion device also includes a pin actuator so that the movable pin can be moved into place in an implant. A method of attaching an implant to an implant insertion device is disclosed, as well as a method of detaching an implant from an implant insertion device. Finally, a method of inserting an implant with an implant insertion device is provided.

Abstract: An assembly of a gauge block and tool for determining the size and shape of space between two adjacent vertebrae. There are a plurality of gauge blocks of different sizes and shapes for determining the vertebral space for subsequent insertion of a permanent artificial spinal disc. As such, a kit with vertebral gauge blocks is disclosed. A method of providing the assembly is also included herein.

Abstract: A screwdriver having a handle and a scale for measuring torque transmitted to a screw and having a beam-type spring for transmitting the screwing torque. The handle and spring have a lost-motion connection therebetween, and there is limit stop in that connection. The handle is sealed against the entry of debris. The method of making the screwdriver is also disclosed.

Abstract: A screwdriver with a spring and a torque measuring scale and a limit stop, useful in the medical arts. A connector provides attachment to a workpiece tool and to a screw which, when fastened, non-rotatably holds the connector which in turn pilots a handle for the driving rotation of the screwdriver. The handle is short and the spring is a helical spring. A method of assembling the screwdriver is disclosed along with the embodiment disclosure.
