Abstract: Provided is a thoracic cavity simulator that, for the purpose of training or education in thoracic cavity microscopic surgery, faithfully reproduces the shape and feel of a human body and that can simulate a surgical environment for a human body that has multiple constraints. A device that comprises a model human skeleton that simulates at least ribs, and comprises a casing that houses the model human skeleton, the device being configured such that an opening is provided to a rib section of the casing, such that a diaphragm section can be opened and closed, and such that model organs can be housed inside the ribs of the model human skeleton. The diaphragm section is configured so as to be removable and/or openable and closable, and the model organs housed inside the ribs of the model human skeleton are replaced.

Abstract: A trocar for thoracoscopic surgery includes a cylindrical portion with an elliptical cross section, and an outer flange and an inner flange provided on respective ones of both ends of the cylindrical portion. The cylindrical portion has two planar side wall portions, two arcuate portions connecting the side wall portions at both ends thereof, and a partitioning wall portion partitioning the interior of the cylindrical portion between both side wall portions. Both side wall portions per se and both arcuate portions per se are formed in curved fashion in such a manner that outer surfaces thereof take on a concave shape.

Abstract: A method for producing a light-emitting device comprising: a step of electrically connecting a first electrode provided on one main surface of a semiconductor substrate (element substrate) through a light-emitting layer, and a first lead of a lead frame, so as to oppose each other; a step of electrically connecting a second electrode provided on the rear surface of a surface provided with the light-emitting layer of said element substrate, and a second lead of the above-described lead frame; a step of encapsulating a connecting part of said first electrode and said first lead, and said second electrode, and an electrode part of the second lead, with a transparent resin; and a step of producing a discrete edge by cutting said first lead and the second lead from said lead frame; wherein a film of joining material (joining material film) made of an alloy or a single metal, is formed on the first electrode of said light-emitting element, and a pattern to reduce spreading of said joining material is formed on an e

Abstract: A surface mount type light-emitting unit includes a light-emitting device. A first lead is connected electrically to a first electrode of the light-emitting device. A second lead is connected electrically to a second electrodc of the light-emitting device. A clear insulator seals the light-emitting device, a section connecting the first electrode to the first lead and a section connecting the second electrode to the second lead. An end of the first lead, forming a reflecting section, is molded into a cup-shaped portion having a flat bottom. The light-emitting device is bonded to the flat bottom. A surface of the reflecting section opposed to the flat bottom is exposed to a surface of thc insulator.
