Abstract: An insertion method includes: specifying a part of a mucous membrane which lies between a nasal cavity and a maxillary sinus and which is located in a space surrounded by an inferior nasal concha, a lacrimal bone, an ethmoid bone, and a palatine bone, as an opening formation position where an opening connected to the maxillary sinus is formed; forming the opening at the opening formation position; and inserting a medical device into the maxillary sinus through the formed opening.

Abstract: A surgical procedure of preparing bone holes to dispose an implanted tendon to a femur when performing reconstruction of a ligament in a knee joint, includes: forming a first bone hole in the femur; and applying ultrasonic vibration from a treatment portion of an ultrasonic treatment instrument to the femur, thereby cutting and expanding the first bone hole from the inside of the knee joint to the first bone hole of the femur along a predetermined depth, and forming a second bone hole having a polygonal shape, an approximately polygonal shape, an elliptical shape or an approximately elliptical shape to receive the implanted tendon.

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 repaired.

Abstract: Provided is a tissue ligation device for ligating tissues. The tissue ligation device includes a suture thread, and a hook-like member having a connecting portion connected to a suture thread-side of the connecting portion of the suture thread and a groove whose inner wall has a locking surface disposed so as to face the suture thread-side connecting portion and allowed to be brought into contact with the suture thread.

Abstract: An ultrasonic probe includes a treatment portion that has a through-hole or concave portions. The through-hole extends from a first outer surface to a second outer surface facing in an opposite direction to that of the first outer surface. The concave portions include a first concave portion on the first outer surface, and a second concave portion on the second outer surface. The treatment portion includes a blade formed along an edge of an opening of the through-hole or the first concave portion. An outer relay surface extends from the blade to the second outer surface and faces away from a center axis of the through-hole or the concave portions. A distance from the center axis to the blade is greater than or equal to a distance from the center axis to the outer relay surface at a position between the blade and the second outer surface.

Abstract: An endoscopic treatment instrument includes a guide sheath. The guide sheath includes a second distal end, which has an inside diameter to insert the insertion portion therethrough so that the distal end of the insertion portion is configured to protrude relative to the second distal end. The guide sheath is inserted through the guide pipe so that the second distal end is configured to protrude relative to the first distal end of the guide pipe.
