Abstract
A robotic surgical system includes a robotic arm and a force detection system coupled to the robotic arm. The force detection system includes a sensor configured to detect a force being applied on a patient as the robotic arm is translated to a position relative to a patient.
Claims20
A robotic surgical system, comprising:
- a robotic arm;
- and
- a force detection system coupled to the robotic arm, the force detection system including:
- a base plate having a first and second end portion;
- a top plate having a first and second end portion and overlying the base plate;
- a pivoting member disposed between the first end portions of the base plate and the top plate and configured to pivotably couple the top plate and the base plate;
- a first sensor coupled to the robotic arm and configured to detect contact between a fixed surface and a surgical instrument of the robotic arm;
- and
- a second sensor disposed between the top plate and the base plate and configured to detect a force applied to the fixed surface.

A method of monitoring a force being applied on a patient, the method comprising:
- applying a force on a fixed surface with a robotic arm;
- detecting contact between the fixed surface and the robotic arm using a first sensor coupled to the robotic arm;
- transmitting a signal to a control device to initiate determination of the force based on the detected contact;
- and
- determining the force applied on the fixed surface using a second sensor.
