Abstract:
A puncture needle including: an elongated approximately-linear main body; a distal end portion that is located at a distal end of the main body and that has a blade surface formed of a distal end surface which is formed inclined with respect to a longitudinal direction; and a bending portion that is provided between the main body and the distal end portion to connect the main body to the distal end portion and that can be passively bent in response to an external force. The distal end portion functions as a bending-direction control portion for setting a bending direction of the bending portion to a direction in which the blade surface is made to face toward an inner side of a bent shape.

Abstract:
An arthroscopical surgical method including administering a fluorescent chemical agent into a joint, which is a treatment target, allowing the fluorescent chemical agent to be adsorbed by a degenerated region that has degenerated from a normal region in a cartilage inside the joint, which is the treatment target, displaying and observing an emission of fluorescence from the degenerated region, which has adsorbed the fluorescent chemical agent, by infrared excitation light on a display through an arthroscope, and allowing a surgeon to recognize the degenerated region in the cartilage inside the joint, which is the treatment target.
Abstract:
Provided is an insertion aid for assisting in insertion of an insertion member having a rigid distal end part into a paranasal sinus or an opening leading to the paranasal sinus. The insertion aid includes a guiding portion having an elongated and curved one end part and configured to guide an insertion route of the insertion member, a guided portion configured to hold the insertion member and movable along the guiding portion, and a support portion supporting the other end part of the guiding portion.
Abstract:
In an arthroendoscopical surgical method, a resection target area, and a freshening treatment area which becomes repair surfaces with bleeding, are identified, and a resection line and a freshening line are drawn on a tear site in a meniscus, which is emphasized by fluorescence with use of a fluorescent medicine under excitation light. Using an ultrasonic treatment tool and an arthroscope, the resection target area is resected by a probe which generates ultrasonic vibrations, based on the resection line and freshening line under visible-light illumination. Thus, an inclined resection surface is formed, and planar repair surfaces with bleeding are joined and repaird.
Abstract:
Provided is an endoscope system including a light source device that outputs signal light that penetrates tissue within a living body; a narrow medical instrument that is inserted into a blood vessel and whose distal end has an emission window from which the signal light supplied from the light source device is emitted; an endoscope that is inserted into the living body and has an imager, which obtains an optical image by acquiring an image of the living body, and a detector, which detects the signal light emitted from the emission window; and an image processor that generates a composite image by combining the optical image with a marker that indicates a position of the signal light.
