Problems solved by technology

Additionally, the use of three cables or pairs of cables to provide motion in three dimensions requires a minimum cross-sectional area to implement and limits the ability to further reduce the cross-sectional area of ​​these tools
Ultimately, the applied force cannot be tailored to provide a force that varies as the jaws open and close depending on the relative position of the jaws

Embodiment Construction

[0097] The embodiments of the jaw assembly and / or the wrist assembly of the present disclosure will be described in detail with reference to the accompanying drawings, in which similar reference numerals are assigned to the same or corresponding components in several views. As used herein, the term "distal" refers to the part of the jaw assembly and / or wrist assembly farther from the user, and the term "proximal" refers to the part of the jaw assembly and / or wrist assembly closer to the user.

[0098] First refer to Figure 1A and 1B , Shows a medical workstation usually used as a workstation 1, which usually includes: a plurality of robot arms 2, 3; a control device 4; and a console 5 connected to the control device 4. The console 5 includes a display device 6, which is specifically configured to display three-dimensional images; and manual input devices 7, 8, through which personnel (not shown, such as a surgeon) can operate in the first operation. The robot arms 2 and 3 are ope...

Abstract

An end effector for use with and in connection with a robotic arm of a robotic surgical system, wherein at least one cable extending from a corresponding motor of a control device of the robotic surgical system controls and / or articulates the end effector. The end effector includes a wrist assembly and a jaw assembly. The jaw assembly includes a cam pulley rotatably supported on at least one support plate of the jaw assembly, wherein the cam pulley is operatively connected to a proximal end of each jaw of the jaw assembly such that rotation of the cam pulley Causes one of opening and closing of the jaw assembly.

Description

[0001] References to related applications [0002] This application claims the priority and rights of U.S. Provisional Patent Application No. 61 / 914,632 filed on December 11, 2013, the entire disclosure of which is incorporated herein by reference. Technical field [0003] The present disclosure relates to medical devices in surgery. More specifically, the present disclosure relates to an end effector for a robotic surgery system. Background technique [0004] Robotic surgery systems are used in minimally invasive medical procedures. Some robotic surgery systems include an operating table supporting the robotic arm, and at least one end effector, such as surgical forceps or grasping tools, mounted on the robotic arm through a wrist assembly. During medical procedures, the end effector and wrist assembly are inserted into a small incision (through a cannula) or a natural hole of the patient, so that the end effector is positioned at the working part of the patient. [0005] The cabl...
