Abstract

A passive end effector of a surgical system includes a base, a first mechanism, and a second mechanism. The base attaches to an end effector coupler of a robot arm positioned by a surgical robot. Thefirst mechanism extends between a rotatable connection to the base and a rotatable connection to a tool attachment mechanism. The second mechanism extends between a rotatable connection to the base and a rotatable connection to the tool attachment mechanism. The first and second mechanisms pivot about the rotatable connections to constrain movement of the tool attachment mechanism to a range of movement within a working plane. The tool attachment mechanism is configured to connect to a surgical saw including a saw blade for cutting.

Description

technical field [0001] The present disclosure relates to medical devices and systems, and more particularly, to robotic systems and related end effectors for controlling the cutting of a patient's anatomy, and related methods and devices. Background technique [0002] There are many surgical interventions that require osteotomy, ie, cutting of an anatomical structure such as bone along a target plane. Total knee arthroplasty usually requires resection of the femoral and tibial epiphysis to remove damaged bone and cartilage and install a knee prosthesis. A surgeon may use an oscillating surgical saw to make five or more cuts on the femur and one or more cuts on the tibia. [0003] During orthopedic surgery, which includes the joint and the knee, it is important to precisely align and stabilize the saw while cutting the desired location on the bone. The limited visibility of the surgical site by the surgeon combined with the difficulty in controlling the movement of the saw ...
