The foregoing application describes a system and method of performing a minimally invasive surgical operation. More specifically, the invention involves the use of disposable cannula and slender dilators of variable lengths, which incorporate a source of illumination to carry light to a surgical site and video capabilities for capturing and displaying images from a CMOS or CCD camera device. According to one embodiment, fiber optics run semi-circumferentially or along walls of the cannula/dilator and terminate at about a centimeter from the distal end of the cannula/dilator, thereby preventing illumination from “bottoming out” at the floor of the incision. According to one alternate embodiment, the light fibers may be fashioned in an annulus around one or more camera chips to provide illumination and video of the surgical site. In still another embodiment, the light fibers may be replaced by light emitting diodes in a more remote light source or alternatively at the distal-tip of the CMOS or CCD camera device.

Devices and methods for surgical retraction are described herein, e.g., for retracting nerve tissue, blood vessels, or other obstacles to create an unobstructed, safe surgical area. In some embodiments, a surgical access device can include an outer tube that defines a working channel through which a surgical procedure can be performed. A shield, blade, arm, or other structure can be manipulated with respect to the outer tube to retract an obstacle. For example, an inner blade can protrude from a distal end of the outer tube to retract obstacles disposed distal to the outer tube. The inner blade can be movable between a radially-inward position and a radially-outward position. The radially-inward position can allow insertion of the blade to the depth of the obstacle to position the obstacle adjacent to and radially-outward from the blade. Subsequent movement of the blade to the radially-outward position can retract the obstacle in a radially-outward direction. The blade can be manipulated remotely, e.g., from a proximal end of the access device or a location disposed outside of the patient. The blade can be manipulated in various ways, such as by rotating the blade relative to the outer tube, translating the blade longitudinally relative to the outer tube, sliding an expander along the blade, driving a wedge between the blade and the outer tube, actuating a cam mechanism of the access device, and/or pivoting the blade relative to the outer tube. 118-.

DEVICES AND METHODS FOR TREATING A LATERAL SURFACE OF A NASAL CAVITY

Номер: US20180125560A1

Автор: Fox William Jason, Saadat Mojgan, SAADAT Vahid

Принадлежит:

The invention disclosed here generally relates to devices that can modify a property of a nerve. Specifically, the subject invention is contemplated to modify the posterior nasal nerve signal conduction in such a way so as to reduce the signals transmitted to the nasal cavity. Reduction or interruption of the nerve signals results in the reduction of the distal organ activity. In particular, embodiments of the present invention allow for increased lateral contact or apposition of the target tissue region having at least one posterior nasal nerve with the end effector surface by lateral and/or longitudinal translation of the end effector relative to the surgical probe shaft. This improved lateral surface contact has several benefits, including improved patient outcomes and patient safety as the end effector is adequately in contact with target tissue for subsequent ablation therapy. 1. A method for treating a tissue region within a nasal cavity of a patient , the method comprising:inserting a distal end of a surgical probe into a nasal cavity of a patient through a nostril of the patient in a first configuration, wherein the surgical probe comprises an outer shaft, an inner shaft positioned within a lumen of the outer shaft and translatable relative to the outer shaft, and an end effector coupled to a distal end of the inner shaft, wherein a distal portion of the inner shaft in the first configuration is substantially aligned with a longitudinal axis of the outer shaft and the end effector is positioned a first distance from a distal end of the outer shaft;advancing the distal end of the surgical into the nasal cavity with the surgical probe in the first configuration;translating the inner shaft relative to the outer shaft so that the surgical probe is deployed to a second configuration, wherein the end effector is translated longitudinally to a second distance greater than the first distance away from the distal end of the outer shaft and laterally away from the ...
