Embodiment Construction

[0092] exist figure 1 A surgical instrument according to aspects of the invention is generally shown in . Surgical instrument (10) includes a plurality of segments (12, 14, 16, 18, 20, and 22) connected to a rigid shaft (24). The rigid shaft (24) is connected to the instrument base ( figure 1 not shown). An instrument tip (26), also referred to herein as an end effector, is attached to the segment (22) furthest from the rigid shaft (24).

[0093] Such as figure 2As shown, the first section (12) is fixedly connected to the rigid shaft (24) by a splined connection (12a). The first section (12) includes a generally cylindrical body (12b) having a splined connection (12a) at one end thereof and a mounting feature (12c) at the other end thereof. The splined connection (12a) is 4 mm long and includes eight protrusions (12d) extending radially from a central lumen (12e). Each of said eight protrusions (12d) is evenly spaced with a length of 1.7 mm measured from the central axi...

Abstract

A surgical instrument comprising: a rigid shaft, at least one elbow joint hingedly coupled to the rigid shaft and a wrist joint coupled to the at least one elbow joint, wherein the wrist joint is configured to provide a first degree of freedom of movement and a second degree of freedom of movement, wherein the second degree of freedom of movement is substantially perpendicular to the first degreeof freedom of movement.

Description

technical field [0001] The present invention provides a surgical instrument, a robotic arm and a control system for the robotic arm. Background technique [0002] Traditional laparoscopic manual instruments consist of a handle, a rigid shaft and a functional end effector such as, for example, a grasper, scissors or a suction channel. Surgeons usually use two laparoscopic instruments at the same time. Laparoscopic instruments can be positioned within a single port or within multiple ports. The common denominator of all these instruments is that motion is transmitted from the handle to the end effector by utilizing the fulcrum effect between the rigid shaft and the port into which the instrument is inserted. Instruments used in laparoscopic surgery typically provide four degrees of freedom. Taking transanal endoscopic microsurgery as an example, the working space available to the surgeon is very limited, which means that manipulating the handle of the prior art instrument t...
