［産業上の利用分野］
本発明は臓器内に生ずる結石を静的に破砕する
時に使用する結石破砕剤の充填器具に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a device for filling a stone-crushing agent for use in statically fragmenting stones formed within an organ.
［従来の技術］
腎臓、尿管、膀胱といつた尿の通路にしばしば
結石ができるが、この結石を除去するためには切
開手術による摘出が一般に行なわれて来た。[Prior Art] Stones often form in the urinary passages between the kidneys, ureters, and bladder, and in order to remove these stones, they have generally been removed by open surgery.
近年、切開手術を行なうことなく体外に結石を
取り出す手法として、爆薬により体内で結石を破

特に尿管のような狭小なところでは危険な結果を
もたらすことが考えられる。 In recent years, as a method for removing stones from the body without performing open surgery, a technique has been developed in which the stones are crushed inside the body using explosives and the reduced mass is removed using a body cavity tube. However, even if the amount of explosives used is small, it is predicted that the gas generated during the explosion will cause damage to organs.
Particularly in narrow areas such as the ureter, dangerous consequences may occur.

進行に伴つて発現する膨張圧により結石を破砕す
ることが可能であることを見出した。 In order to prevent this phenomenon, the inventors of the present invention have conducted various studies and found that the hole drilled in the stone to be crushed should be filled with a substance that reacts with water, hydrates and expands, and generates expansion pressure. We found that it is possible to crush stones by the expansion pressure that develops as the hydration reaction progresses.

In addition, if the stone crushing agent is left in the air for a long period of time, it will absorb moisture and carbon dioxide from the air.
Because it has a tendency to deteriorate in performance due to weathering, strict storage is required.

を目的とする。 The present invention was made in order to solve these problems, and the stone-crushing agent does not deteriorate by storing it while blocking outside air, and the ratio of water to stone-crushing agent (water ratio) when used is reduced. It is an object of the present invention to provide a stone crushing agent filling device in which the reaction time is always constant and the reaction time does not change.

It is made by filling it with. The tube is made of glass, resin such as Teflon, metal, etc., and one end is sealed, and the other end is sealed and joined to the bag-like container. The bag-like container is made of an elastic or flexible material that does not permeate gas or liquid, such as synthetic rubber or resin, and may be integral with the tube or may be joined to the tube. This bag-like container is filled with a certain amount of stone-crushing agent, and the volume of the void area (the part of the bag-like container excluding the stone-crushing agent) is equal to the theoretical amount of water required for the hydration reaction of the stone-crushing agent. The volume should be the same or slightly larger. Next, the void area is evacuated and stored. Instead of vacuum, nitrogen, argon, helium gas, etc. may be filled. Further, silica gel, quicklime, etc. may be mixed into the stone crushing agent to impart dehumidifying properties.

The stone crushing agent and water are mixed by crushing them several times with fingertips to form a slurry. Next, a stone-crushing agent is filled into the hole of the stone from this crushing tool through a body cavity tube installed in advance to crush the stone.
