Abstract

A robotic surgical system can include one or more adjustable arm supports that support one or more robotic arms. The adjustable arm supports and/or robotic arms can be configured to be deployed from low mount positions, for example, from positions below the surface of the table. The robotic arms can include a plurality of joints providing a plurality of degrees of freedom. The joints may be grouped into a proximal shoulder, an elbow, and a distal wrist. The robotic arms can include one or more redundant degrees of freedom. An insertion mechanism, associated with the robotic arm and configured for providing insertion of an instrument along an assertion axis, can be provided at a distal end of the robotic arms.

Claims

1. A system, comprising:

a table;

a table support below the table;

an arm support coupled to at least one of the table or the table support;

a first robotic arm coupled to the arm support, wherein the first robotic arm comprises a proximal portion and a distal portion and at least four powered joints between the proximal portion and the distal portion, wherein each of the joints is capable of being actuated independently of the other joints, wherein the first robotic arm comprises an instrument drive mechanism fixedly attached to the first robotic arm;

a surgical instrument comprising;

an elongated shaft;

a base configured to removably attach to the instrument drive mechanism of the first robotic arm to attach the surgical instrument to the first robotic arm,

wherein the base comprises an attachment interface configured to attach to a proximal face of the instrument drive mechanism,

wherein the elongated shaft is coupled to the base and configured to translate through a central passage extending through the instrument drive mechanism and the base, and

wherein the base of the surgical instrument comprises an insertion mechanism configured to provide translation of the elongated shaft relative to the base along an insertion axis such that the elongated shaft can be inserted through the base while a position of the base remains stationary, wherein the insertion mechanism comprises at least one pulley positioned within the base that is engaged with a cable connected to the elongated shaft; and

a second robotic arm coupled to the arm support.

2. The system of claim 1, wherein the first robotic arm is translatable relative to the second robotic arm.

3. The system of claim 1, wherein the insertion mechanism is built within the instrument itself independently of the first robotic arm.

4. The system of claim 1, wherein the first robotic arm is capable of at least seven degrees of freedom, wherein at least one of the degrees of freedom is redundant.

5. The system of claim 1, wherein the first robotic arm and the second robotic arm are capable of being stowed beneath the table.
