Abstract
Technologies for determining seating of an orthopaedic implant during an orthopaedic surgical procedure includes an impaction sensor and an impaction analyzer. The impaction sensor produces sensor data, in response to an impaction between an orthopaedic mallet and a surgical tool indicative of an initial impact and a secondary impact of the impaction. The impaction analyzer analyzes the sensor data to determine a temporal length between the initial and secondary impacts and determines whether the orthopaedic implant is sufficiently seated into the bone based on the temporal length.
Claims20
An orthopaedic mallet for use in an orthopaedic surgical procedure to implant an orthopaedic implant into a bone of a patient, the orthopaedic mallet comprising:
- an impaction sensor configured to produce sensor data indicative of an impaction of the orthopaedic mallet and a surgical tool, wherein the impaction comprises an initial impact between the orthopaedic mallet and the surgical tool and a secondary impact between the orthopaedic mallet and the surgical tool that occurs subsequent to the initial impact;
- and
- an impaction analyzer configured to analyze the sensor data to detect the initial impact and the secondary impact, determine a temporal length between the initial impact and the secondary impact, and determine whether the orthopaedic implant is sufficiently seated into the bone based on the temporal length.
An orthopaedic mallet for use in an orthopaedic surgical procedure to implant an orthopaedic implant into a bone of a patient, the orthopaedic mallet comprising:
- an impaction sensor configured to produce sensor data indicative of an impaction of the orthopaedic mallet and a surgical tool, wherein the impaction comprises an initial impact between the orthopaedic mallet and the surgical tool and a secondary impact between the orthopaedic mallet and the surgical tool that occurs subsequent to the initial impact;
- and
- an impaction analyzer configured to analyze the sensor data to detect the initial impact and the secondary impact, determine a temporal length between the initial impact and the secondary impact, and determine whether the orthopaedic implant is sufficiently seated into the bone based on the temporal length,
- wherein the impaction comprises a second impaction and the temporal length comprises a second temporal length,
- wherein the impaction sensor is further configured to produce additional sensor data indicative of a first impaction of the orthopaedic mallet and the surgical tool that occurred prior to the second impaction, wherein the first impaction comprises an initial impact between the orthopaedic mallet and the surgical tool and a secondary impact between the orthopaedic mallet and the surgical tool that occurs subsequent to the initial impact of the first impaction, and
- wherein the impaction analyzer is further configured to analyze the additional sensor data to detect the initial impact of the first impaction and the secondary impact of the first impaction, determine a first temporal length between the initial impact of the first impaction and the secondary impact of the first impaction, and determine that the orthopaedic implant is sufficiently seated in response to a determination that a difference between the first temporal length and the second temporal length is less than a referenced amount.
A system for determining whether an orthopaedic implant is sufficiently seated in a bone of a patient during an orthopaedic surgical procedure, the system comprising:
- an impaction sensor configured to produce sensor data indicative of an impaction of an orthopaedic mallet and a surgical tool, wherein the impaction comprises an initial impact between the orthopaedic mallet and the surgical tool and a secondary impact between the orthopaedic mallet and the surgical tool that occurs subsequent to the initial impact;
- and
- an impaction analyzer configured to analyze the sensor data to detect the initial impact and the secondary impact, determine a temporal length between the initial impact and the secondary impact, and determine whether the orthopaedic implant is sufficiently seated into the bone based on the temporal length.
