Disclosed herein is a joint evaluation device and corresponding systems and methods for evaluating ligaments and other soft tissue connections between, for example, a tibia and a femur at a knee joint. The joint evaluation device being arranged and configured to induce and measure forces while positions of the tibia and femur are monitored. Some embodiments use a computer assisted surgery device to track positions of the tibia and the femur, and may include a computing device configured to evaluate the forces measured between a first engagement portion and a second engagement portion of the joint evaluation device to output information related to the status of the ligament and other soft tissue connections prior to any bone resections being made to the tibia or the femur.

Knee ligament evaluation system and method

A cutting assembly () is configured for use with an electromagnetic tracking system (). The cutting assembly comprises a bur assembly () and a sheath assembly (). The sheath assembly comprises a sensor () configured to measure an electrical field around the cutting assembly, a wire () configured to operably connect the sensor and an external computing device (), and a sensor mount () affixed to at least a portion of the sheath assembly, the sensor mount configured to house the sensor and at least a portion of the wire. The sheath assembly is configured to receive at least a portion of the bur assembly such that any impact from magnetic interference caused by, for example, a cutting device () within the bur assembly on the sensor is minimized when the cutting device is cutting a patient's bone.

Cutting assembly for use with electromagnetic tracking

A device for penetrating tissue is provided that has a driving actuator with a body and motor shaft that is reciprocated. A coupler is attached to the motor shaft, and a key engages the driving actuator and coupler and limits rotational motion of the motor shaft and permits linear motion of the motor shaft. A penetrating member is carried by the coupler, and linear motion of the motor shaft is translated to the penetrating member to linearly reciprocate the penetrating member.

Device and method for less forceful tissue puncture

A medical device for reducing the force necessary to penetrate living being tissue using a variety of reciprocating motion actuators. The reciprocating actuator drives a penetrating member, such as a needle, through the tissue at a reduced force while the device detects the passage of the penetrating member through the tissue. Upon passage of the penetrating member through the tissue, a feedback system monitors electromechanical properties of a control signal of the device and automatically modifies control based thereon, e.g., electrical power to the reciprocating actuator is automatically terminated.
