5 . The ligament retractor system of claim 1 , wherein the one or more sensors comprises an optical sensor configured to provide 3D visualization data of an anatomical landmark proximate the ligament retractor.
6 . The ligament retractor system of claim 1 , wherein the one or more sensors comprises a Hall effect sensor configured to detect proximity of a metallic surgical instrument to the ligament retractor.
7 . The ligament retractor system of claim 1 , wherein the ligament retractor comprises the one or more sensors.
8 . A ligament retractor system comprising:
a ligament retractor comprising one or more sensors; and
a processing unit configured to receive and process data from the one or more sensors;
wherein the one or more sensors are configured to detect proximity of a cutting device to the one or more sensors.
9 . The ligament retractor system of claim 8 , wherein the one or more sensors comprise one or more Hall effect sensors.
10 . The ligament retractor system of claim 8 , wherein the cutting device comprises a material comprising a magnetic field detectable by the one or more sensors.
11 . The ligament retractor system of claim 8 , further comprising a cutting guide, wherein the cutting guide is configured to be coupled to the ligament retractor and to receive and guide the cutting device.
12 . The ligament retractor system of claim 8 , further comprising a patient specific instrument (PSI) retractor attachment configured to be received by, and operatively engage, the ligament retractor.
13 . The ligament retractor system of claim 12 , further comprising a cutting guide, wherein the cutting guide is configured to be coupled to the PSI retractor attachment and to receive and guide the cutting device.
14 . The ligament retractor system of claim 8 , wherein the ligament retractor comprises a medial collateral ligament (MCL) retractor.
15 . The ligament retractor system of claim 8 , further comprising a bone saw comprising a saw blade and a battery pack configured to provide electric voltage to power the bone saw, wherein:
the battery pack comprises an indicator and a circuit board configured to receive a trigger voltage from the one or more sensors;
the one or more sensors are configured to communicate the trigger voltage to the circuit board upon detection of the proximity of the saw blade;
the circuit board is configured to activate the indicator upon receipt of the trigger voltage; and
the circuit board is further configured to switch off the electric voltage from the battery pack to the bone saw upon receipt of the trigger voltage.
16 . A ligament retractor system comprising:
a ligament retractor comprising one or more sensors; and
a processing unit configured to receive and process data from the one or more sensors;
wherein the one or more sensors are configured to confirm placement of the ligament retractor during a surgical procedure.
17 . The ligament retractor system of claim 16 , wherein the one or more sensors comprise one or more inertial measurement unit (IMU) sensors configured to obtain positional data of the ligament retractor.
18 . The ligament retractor system of claim 16 , wherein the ligament retractor comprises a medial collateral ligament (MCL) retractor.
19 . The ligament retractor system of claim 16 , wherein the ligament retractor further comprises a Hall effect sensor and the ligament retractor system further comprises a cutting device, wherein the Hall effect sensor is configured to detect a proximity of the cutting device to the ligament retractor.
20 . The ligament retractor system of claim 19 , wherein the cutting device comprises a material comprising a magnetic field detectable by the one or more sensors.
21 . A ligament retractor system comprising:
a ligament retractor configured to retract a ligament during a surgical procedure; and
a patient specific instrument (PSI) retractor attachment configured to be received by, and operatively engage, the ligament retractor;
wherein the PSI retractor attachment is configured to engage an anatomical landmark.
22 . The ligament retractor system of claim 21 , wherein the ligament retractor comprises one or more sensors configured to identify a location of one or more anatomical landmarks or instruments.
23 . The ligament retractor system of claim 21 , wherein the PSI retractor attachment comprises one or more sensors configured to identify a location of one or more anatomical landmarks or instruments.
24 . The ligament retractor system of claim 21 , further comprising a cutting guide, wherein the cutting guide is configured to be coupled to the PSI retractor attachment and to receive and guide a cutting device.
