There is provided a repeated type organ fixing instrument having a plurality of suturing tools. The organ fixing instrument includes a rod-shaped engaging portion, a suture fixed to the engaging portion, a puncture needle for housing a plurality of the engaging portions. A plurality of the engaging portions are extruded one by one from the puncture needle by the operation of a operation unit main body. The suture fixed to at least one of the plurality of engaging portions is inserted within the inside of the puncture needle and wherein the other suture is derived from the inside to the outside of the puncture needle.

Repeating-type organ-fastening tool

A medical device includes a main body elongated in a vertical direction. A guide section protrudes from a lower end of the main body in a direction crossing the vertical direction and includes first and second guide holes. A first unit includes a first puncture needle slidably supported by the main body near an upper end of the first puncture needle in the vertical direction and having a sharp lower end slidably inserted into the first guide hole from above. The first unit has a first holding plate integrally fixed to the first puncture needle. A second unit includes a second puncture needle slidably inserted into the second guide hole from above and a second holding plate integrally fixed to the second puncture needle. The second holding plate separably abuts on the first holding plate from above. A position of the second guide hole is selectable along the guide section.

Medical device

A medical device () includes a main body (); a first piercing needle () provided slidably with respect to the main body (); a first holding plate () adapted to hold the first piercing needle () and provided slidably on the main body (); and a second holding plate () adapted to hold a second piercing needle () and detachably and movably mounted on the first holding plate (), wherein the second holding plate () is mounted so as to move to the first holding plate () in a predetermined direction.

Medical device and method of fixing internal organ

A catheter kit for a burrow having a catheter and an obturator and excellent in operability. The catheter comprises a tube having, inside, a nutrient passage leading nutrition or chemicals from the outside of a body to the inside of a stomach and extending along the wall surface of the burrow and a non-balloon type endodwelling member fitted to the tip part of the tube, normally placed in an expanded state and reduced in diameter less than that in the expanded state when an external force acts thereon by the obturator, and indwelled in the stomach in a buried state in a living body. The obturator comprises a guide wire passage detachably engaged with the catheter and allowing a guide wire installed in the obturator ranging from the tip to the midway thereof to be inserted therein and an operation part for transmitting the external force to the endodwelling member fitted to the rear end thereof. The rear end part of the guide wire passage and the operation part are arranged in a separated state.
