An assembly (1) comprising at least one steerable invasive instrument (10,20) and an access device (30) for introducing the instrument into an object via an access port of the object. The steerable instrument (10,20) comprises an elongated tubular body (18) having a proximal end part (11,21) comprising at least one flexible zone (14,15,24,25), a distal end part (13,23) comprising at least one flexible zone (16,17,26,27), and a rigid intermediate part (12,22). The instrument further comprises a steering arrangement for translating a deflection of at least a part of the proximal end part (11,21) relative to the rigid intermediate part (12,22) into a related deflection of at least a part of the distal end part (13,23). The access device (30) comprises a deflection setting arrangement for setting at least one angle between at least a part of the proximal end part (11,21) and the rigid intermediate part (12,22) of the instrument.

The embodiments disclosed herein relate to various medical device components, including components that can be incorporated into robotic and/or in vivo medical devices. Certain embodiments include various medical devices for in vivo medical procedures. In an exemplary embodiment of a robotic device, the device has a main body, a right arm, and a left arm. Each of the left and right arms is comprised of 2 segments: an upper arm (or first link) and a forearm (or second link), thereby resulting in each arm having a shoulder joint (or first joint) and an elbow joint (or second joint). In certain implementations, each of the left arm and right arm is capable of four degrees of freedom.

FIG. 3A: 140 Canal à endoscope 200 Endoscope de petite taille 130 Canal pour le robot 180 Canal d'aspiration 104 Extrémité distale 100 Endoscope de grande taille A master - slave robotic endoscopy system includes a flexible primary endoscope probe having at least one tool channel for carrying a tendon-sheath driven robot arm and corresponding end effector, and a secondary endoscope probe channel for carrying an imaging endoscope. The imaging endoscope provides enhanced image capture range relative to a distal end of the primary endoscope probe by way of a secondary endoscope probe channel distal opening proximally offset from the primary endoscope probe distal end; a ramp structure disially carried by the primary endoscope probe; and/or one or more actuatable distal imaging endoscope regions. Robot arms can include joint primitives that enable robot arm / end effector manipulation in accordance with intended degrees of freedom. A set of quick connect / disconnect interfaces couple an actuation controller to one or more actuation assemblies insertable into the tool channel(s), where each actuation assembly includes tendon-sheath elements, a robot arm, and its corresponding end effector.
摘要:
An articulated tool positioning apparatus comprising a base member, an intermediate member, an end member and a first tool holder arranged in succession, each of the base member, intermediate member, end member and tool holder having a respective central opening. A first plurality of coupled guides id positioned between the base member and the intermediate member and a second plurality of coupled guides is positioned between the intermediate member and the end member. A third plurality of coupled guides is disposed between the end member and the tool holder. The base member, intermediate member, end member, first tool holder and first second and third pluralities of coupled guides all have a central opening and guide openings or securing points for securing pluralities of flexible control links to the base member or to an object separated from the base member. Pushing or pulling control links of a first plurality of control links causes the base member, the first plurality of coupled guides, the intermediate member, the second plurality of coupled guides and the end member to selectively define a continuous curve. A second plurality of control links causes the end member to maintain an orientation generally the same as the base member, when any of the other flexible control links is pushed or pulled. Pushing or pulling control links of a third plurality of control links causes the tool holder to be selectively moved into any of a plurality of orientations, such that the third plurality of coupled guides between the end member and the tool holder defines a continuous curve from the end member to the tool holder. At least one mechanism for pushing and pulling the flexible control links is described and a use of the apparatus for positioning a tool for laparoscopic surgery applications is described.
摘要:
The various embodiments disclosed herein relate to various robotic medical devices, including robotic devices that are disposed within a body cavity and positioned using a support component disposed through an orifice or opening in the body cavity. Additional embodiments relate to devices having arms coupled to a device body wherein the device has a minimal profile such that the device can be easily inserted through smaller incisions in comparison to other devices without such a small profile. Further embodiments relate to methods of operating the above devices.
摘要:
The present invention relates to an improved cannula that enables a plurality of applications to such as tools to be utilised through a single cannula. According to the present invention there is a cannula having a distal end for insertion into a body, the distal end defining an opening to a primary conduit extending along the longitudinal axis of the cannula. The cannula further comprises a tool element for providing a tool function at or adjacent the distal end of the cannula. At least a portion of the tool element is arranged to be moveable outwardly relative to the longitudinal axis of the cannula. Accordingly, it is beneficial that more than one function can be provided at the distal end of the cannula reducing the trauma to the patient and improving access for the surgeon.
