A clipping instrument for biological tissues equipped with an outer tube which can be inserted into a biological cavity, an operating member freely passed through the outer tube, an operating wire freely passed though the operating member, a self-opening holder which can be opened and closed by the action of the operating member attached to the edge of the operating wire, and a self-opening clop having a clipping member for clopping a biological tissue which is attached to the edge of the holder in a detachable manner by opening/closing the holder. Using this clopping instrument, a lesion site can be surely clipped over a long period of time in ligating a breeding site in a biological tissue, stitching a laceration, making in excision of a mucosal tissue and so on with an endoscope.

Clip and clipping instrument for biological tissues

An instrument for coronary artery bypass graft surgery has at least three sets of suction units, respectively provided with a flexible tube; a suction head disposed at an end portion of the flexible tube; a three-way cock mounted on the flexible tube; and a retainer which retains the flexible tube.

Instrument for coronary artery bypass graft surgery

A clipping device improves defects that the clip can not be again opened once the clip is closed, and that it is necessary to execute the operation in a state in which the clip is not sufficiently opened. The invention provides a clip device for an endoscope constituted by a clipping means having a pair of arm portions which are allowed to be opened and closed, an operating means for holding the arm portions of the clipping means so as to open and close the arm portions, a fixing means for fixing the arm portions after closing the arm portions, and an arranging means for arranging the fixing means in an outer side of the arm portion.

Clip device for endoscope and clip for endoscope for use therein

A medical instrument, or collection instrument, for collecting foreign material, such as calculuses and clips that have fallen in the abdominal cavity, is disclosed. The collection instrument includes a tube ( ) that is hollow in the longitudinal direction and a collection bag ( ) arranged at one end of the tube (1). The collection bag includes a barrier member having a fluid passage characteristic.

Recovery instrument

A fluid circuit connects a pressure applying portion ( ) and a distal device ( ) to charge fluid into the distal device ( ). The fluid circuit includes a controller ( ) to control the movement of ligating rings ( ). The controller ( ) senses a pressure drop in the distal device ( ) when one or a plural number of the ligating rings ( ) are separated from the distal device ( ). The movement of the ligating rings ( ) is stopped in accordance with the pressure drop so that at least two or more of the ligating rings can be separated at a time. Accordingly, ligation of esophageal varices and internal hemorrhoids can be performed successively.

Continuous ligation kit

An endoscopic ligation kit including an inner cylinder, an outer cylinder having at least two step portions of diminishing outer radii formed on the outer periphery of its distal end portion, and a slide cylinder provided between the inner cylinder and the outer cylinder. The outer cylinder has a notch extending from its distal end portion to its maximum outer diameter portion. The slide cylinder has at its distal end portion a projection which conforms in size to the notch, and has steps and the projection is fitted in the notch. O-rings are mounted respectively on the outer periphery of the distal end portion of the inner cylinder and the step portions of the outer cylinder.

Endoscopic ligation kit

Auxiliary device for pulsatile coronary artery bypass

A cardio assist system has an integrated cardio-assist catheter including a multi-lumen tube and an inflatable/deflatable balloon provided on a distal end portion of the tube, a blood pump connected to the proximal end of a main lumen in the catheter, and a balloon driver for supplying and discharging a gas to and from the balloon so as to repeatedly inflate and deflate the balloon. Disclosed also is a device for inserting the cardio assist system to a living body safely, accurately and promptly. A combined use of the cardio assist system and the insertion device enables a quick set up a strong assisted blood circulation system.
