摘要:
A flexible spine for use in one or more surgical instruments including a catheter and/or sheath of a robotic instrument system. The spine includes an elongate body that defines a central lumen and that is a unitary structure having a plurality of discrete sections, each of which has a distinguishing structural attribute that differentiates it from the other sections. Such distinguishing structural attributes may include, without limitation, materials, material attributes, shapes, sizes and/or attributes related to apertures in a wall of the elongate body, such as a number, shape, size, spacing and degree of overlap of such apertures. The arrangement of discrete, structurally different sections results in varying flexibility of the elongate spine and of corresponding sections of a surgical instrument incorporating the spine.

A robotic catheter system includes a controller with a master input device. An instrument driver is in communication with the controller and has a guide instrument interface including a plurality of guide instrument drive elements responsive to control signals generated, at least in part, by the master input device. An elongate guide instrument has a base, distal end, and a working lumen, wherein the guide instrument base is operatively coupled to the guide instrument interface. The guide instrument includes a plurality of guide instrument control elements operatively coupled to respective guide drive elements and secured to the distal end of the guide instrument. The guide instrument control elements are axially moveable relative to the guide instrument such that movement of the guide instrument distal end may be controlled by the master input device.

The apparatus of one embodiment of the present invention is comprised of a flexible sheath instrument, a flexible guide instrument, and a tool. The flexible sheath instrument comprises a first instrument base removably coupleable to an instrument driver and defines a sheath instrument working lumen. The flexible guide instrument comprises a second instrument base removably coupleable to the instrument driver and is threaded through the sheath instrument working lumen. The guide instrument also defines a guide instrument working lumen. The tool is threaded through the guide instrument working lumen. For this embodiment of the apparatus, the sheath instrument and guide instrument are independently controllable relative to each other.

Surgical accessories are presented in vivo and used by surgical tools in the surgical site to perform additional tasks without the need to remove the tools from the surgical site for tool change or instrument loading. Some accessories need to be actuated to effect a predetermined treatment, such as an aortic punch, clamps, pliers, and the like. For such accessories, the actuation can conveniently be performed by an operator such as an assistant remotely from outside the patient's body while placement of the accessories takes place in the surgical site by manipulating the accessories using robotic surgical tools in the site. A lockdown feature may be incorporated in accessories to lock them in place remotely from outside the surgical site upon actuation.
摘要:
An apparatus deployed through a laparoscopic incision in a body wall to apply an external lifting force over a large area of the body wall. The apparatus comprises a body wall engaging element and an elongate lifting member. The body wall engaging element is capable of passing in a packaged state through the laparoscopic incision, is inflatable to an inflated state, and includes, in the inflated state, a plane lifting surface. The elongate lifting member includes a distal portion connected to the plane lifting surface, and capable of passing through the laparoscopic incision. A proximal portion receives the external lifting force in a direction that moves the body wall engaging element into contact with the body wall. A method for lifting a body wall by applying an external lifting force to a large area of the body wall through a laparoscopic incision. The lifting device is provided that includes an body wall engaging element capable of passing through the laparoscopic incision in a packaged state. The lifting device also includes a lifting member including a distal portion to which the body wall engaging element is connected. The body wall engaging element and the distal portion of the lifting member are advanced through the laparoscopic incision. The body wall engaging element is inflated to an inflated state to provide a plane lifting surface. Finally, the external lifting force is applied to the proximal portion of the lifting member to move the lifting surface into contact with the body wall.
摘要:
An apparatus for retracting an organ to gain access to treat a tissue. The apparatus has a main envelope, a second envelope, a first inflation device and a second inflation device. The main envelope encloses a main chamber, and includes a window and a removable window. The second envelope covers substantially all the main envelope, except the window and the removable window. The second envelope and the main envelope enclose a second chamber outside the main chamber. The first inflation device passes a fluid into the main chamber to expand the main chamber and the second chamber from a compacted state to retract the organ. The second inflation device passes a fluid into the second chamber to further expand the second chamber to maintain the organ in its retracted state after fluid has been released from the main chamber.
