摘要： A retractor has a rigid piercing tube and an expansion body. The expansion body has an introduction tube which is received within the piercing tube, a movable wire which is received within the introduction tube, and stationary wires which are arranged around the movable wire. The proximal end of each of the stationary wires is affixed to the distal end of the introduction tube. The distal end of each of the stationary wires is joined to the distal end of the movable wire. The respective proximal ends of the piercing tube, the introduction tube, and the movable wire are respectively joined to first, second, and third grip sections.

摘要： A developing body includes: an excluding portion including a movable wire and fixing wires arranged around the movable wire, a distal end of the movable wire and distal ends of the fixing wires being connected to each other; an insertion tube allowing the movable wire to pass therethrough; and a restriction member that is connected to a proximal end of the movable wire. The restriction member restricts the movement of the movable wire when the restriction member abuts against the first grip portion. When the first grip portion and the second grip portion are moved relative to each other so as to be close to each other in this state, the excluding portion is developed by bringing the distal end of the insertion tube and the distal end of the movable wire to be close to each other to deflect the fixing wire.

摘要： The present invention is a retractor for displacing an organ within the body cavity or the inner wall of a hollow organ, the retractor being provided with: a housing tube; an expansion body which can be housed into and extend from the housing tube; and a grip connected to the proximal ends of the housing tube and the expansion body. The expansion body is provided with: a displacing part configured from a movable wire and multiple fixed wires disposed in the periphery of the moveable wire; and an introduction tube which is disposed along the displacing part and through which the movable wire penetrates. Moreover, when the expansion body is expanded, the displacement part is designed so that, from among the expansion angles formed by two adjacent fixed wires, one expansion angle (θ2) becomes larger than the other expansion angle (θ1).

摘要： There is provided an insufflation system and an insufflation apparatus which can prevent a pressure inside a lumen from rapidly increasing and can achieve operability matched to a sense an operator. The insufflation apparatus is connected to an endoscope and an insertion assisting tool which guides the endoscope into the gastrointestinal tract. Carbon dioxide can be insufflated into a gastrointestinal tract of a patient through an internal conduit of the endoscope according to an operator's operation (manual insufflation). When the operator instructs the insufflation apparatus to perform the automatic insufflation, carbon dioxide is intermittently insufflated into the gastrointestinal tract through the insertion assisting tool so as to make the pressure inside the gastrointestinal tract become a set pressure (automatic insufflation). The insufflation flow rate of the manual insufflation is switched between the high flow rate and the low flow rate according to ON/OFF state of the automatic insufflation.

摘要： Disclosed is a hemostatic agent applicator capable of effectively placing a fluid hemostatic agent on an incision surface. The present invention is a hemostatic agent applicator for use in disposing a fluid hemostatic agent, including a tool body in which a hollow part surrounded by a wall part is formed and which includes an open end part on a downstream side of the wall part, and an inlet provided to a portion of the wall part of the tool body to communicate with the hollow part. This hemostatic agent applicator is useful in medical settings relating to surgical procedures, particularly for surface bleeding of a liver and internal organ surgery such as a spleen and fibroid enucleation. An applicator further reduced in size can be applied not only in abdominal surgery, but in endoscopic surgery as well.

摘要： There is provided an insufflation system and an insufflation apparatus which can prevent a pressure inside a lumen from rapidly increasing and can achieve operability matched to a sense of an operator. When the operator operates an air/water supply button of the endoscope, the gas is insufflated into a gastrointestinal tract of a patient through an internal conduit of the endoscope (manual insufflation). Meanwhile, the insufflation apparatus is connected to an insertion assisting tool which guides the endoscope into the gastrointestinal tract. When the insufflation apparatus automatically performs insufflation, the gas is intermittently insufflated into the gastrointestinal tract of the patient so as to maintain the pressure inside the gastrointestinal tract at the set pressure (automatic insufflation). The average flow rate of the gas in the automatic insufflation is set to be less than or equal to the insufflation flow rate in the manual insufflation.
