Problems solved by technology

Although current laparoscopy limits dexterity, and robotics restores dexterity, presently, existing systems, using manipulators both with and without haptic feedback, are generally too bulky and heavy for many minimally invasive procedures, or are too weak and imprecise for surgery.

Embodiment Construction

[0033]A description of preferred embodiments of the invention follows.

[0034]The surgical robotic system of the present invention, illustrated generally at 10 in FIG. 1, although preferably used to perform minimally invasive surgery, can also be used to perform other procedures as well, such as open or endoscopic surgical procedures. Certain details of the operation of the system 10 are described in U.S. application Ser. No. 10 / 014,143 filed Nov. 16, 2001, by Brock and Lee, the entire contents of which are incorporated herein by reference.

[0035]The surgical instrument system 10 includes two main components, a master station M and a slave station S. At the master station M, a surgeon 12 manipulates an input device 13 to direct the operation of a surgical instrument 14 of the slave station S to perform a medical procedure on a patient P lying on an operating table T. Although there are shown two surgical instruments 14 positioned on either side of an endoscope 15 and controlled by a re...

Abstract

A medical system and surgical instrument adapter are provided. The medical system comprises a surgical instrument carrying a distal tool configured for performing a medical procedure on a patient, an adapter having a clam-shell configuration configured for removably receiving a proximal end of the surgical instrument, and a drive unit configured for being coupled to the adapter to control the movement of the surgical instrument within at least one degree-of-freedom. The surgical instrument adapter may comprise a base portion configured for receiving a proximal end of the surgical instrument, and a clam-shell that pivots relative to the base portion between a first position that encloses the proximal end of the surgical instrument within the base portion and a second position that allows the proximal end of the surgical instrument to be removed from the base portion.

Description

RELATED APPLICATIONS[0001]This application is a continuation of U.S. application Ser. No. 11 / 762,745, filed Jun. 13, 2007, which is a continuation of U.S. application Ser. No. 10 / 302,804, filed Nov. 21, 2002, now U.S. Pat. No. 7,331,967, which claims benefit of priority from U.S. application Ser. No. 60 / 409,530, filed Sep. 9, 2002. This application is also related to application Ser. No. 11 / 762,743, filed Jun. 13, 2007. The disclosures of these applications are expressly incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]For certain medical procedures, minimally invasive surgery has replaced conventional surgery where the patient's body cavity is open to permit the surgeon's hands and instruments access to the cavity and internal organs. Minimally invasive procedures are typically less traumatic than conventional surgery, in part, because of the significant reduced incision size through which the medical instruments are inserted.[0003]A video camera may be inserted in...
