Systems and methods for navigation and control of an implant positioning device
Systems and methods for navigation and control of an implant positioning device are discussed. For example, a method can include operations for accessing an implant plan, establishing a 3-D coordinate system, receiving tracking information, generating control signals, and sending the control signals to the implant positioning device. The implant plan can include location and orientation data describing an ideal implant location and orientation in reference to an implant host. The 3-D coordinate system can provide spatial orientation for the implant positioning device and the implant host. The tracking information can identify current location and orientation data within the 3-D coordinate system for the implant positioning device and implant host during a procedure. The control signals can control operation of the implant positioning device to assist a surgeon in positioning the implant according to the implant plan.
1. An implant positioning device comprising:
a positioning arm having a distal movable portion in mechanical communication with an articulating joint;
an end effector, configured to contact an implant component during a surgical procedure, operably connected to a plurality of actuators positioned about an exterior periphery of the end effector;
a motor mechanically connected to the plurality of actuators and the articulating joint, configured to:
provide energy to each of the plurality of actuators, thereby allowing the plurality of actuators to impart a linear motion on the end effector; and
provide energy to the articulating joint, thereby allowing the articulating joint to adjust an impact angle of the end effector; and
a control circuit coupled to the motor and configured to:
generate at least one motor control signal,
transfer the at least one motor control signal to the motor, and
as a result of the at least one motor control signal, cause the motor to move one or more of the plurality of actuators to produce one or more impacts on the end effector, wherein the plurality of actuators are configured to induce a rotation on the implant component during insertion of the implant component; and
a communication device configured to:
establish a communication link with a surgical control system; and
receive system control signals from the surgical control system, the system control signals for controlling the insertion of the implant component, wherein the system control signals comprise an impact frequency indication defining how frequently the implant positioning device is to impart the impact force to the implant component.
2. The device of claim 1 , wherein the end effector comprises a retention device configured to retain the implant component in a fixed position relative to the end effector during the insertion of the implant component.
3. The device of claim 1 , further comprising a tracking marker configured to be tracked by a tracking system, thereby providing for monitoring of a position of the implant positioning device during the surgical procedure.
4. The device of claim 1 , wherein the motor is further configured to control extension of the positioning arm.
5. The device of claim 1 , wherein the surgical procedure comprises a hip replacement surgery.
6. The device of claim 1 , wherein the implant component comprises a prosthetic acetabular cup.
7. The device of claim 1 , wherein the control circuit is configured to receive one or more parameters, the one or more parameters comprising an indicator that the implant positioning device is located within a planned position of the implant positioning device.
