REMOVAL TOOL FOR USE IN CONDUIT IN HUMAN BODY
Document Type and Number:
Japanese Patent JPS6485662
Kind Code:
A
Abstract:
PURPOSE: To easily draw a urethra appliance out of the urethra by gliding a shaft more deeply into the hole of a tool to push a magnet into the conical holes of jaws, opening these jaws and attracting a ball mounted at the closing member of an expanded detaining device of the urethra appliance by means of this magnet. CONSTITUTION: The movement in the longitudinal direction of the shaft 32 causes the jaws 48 to extend to the outside of a pipe 31 and forces the end 44 of the magnet 38 to separate and push surfaces 39 and 40 forward, thereby separating the halves 42 and 42 of the jaws and opening the jaws 48. The magnet 38 protrudes through the opened jaws 48 opened therefrom and attracts an object, such as steel ball 12. When the jaws 48 are opened by the longitudinal movement of the magnet 38, a dent 45 is opened and the object, such as ball 12, is housed. When the jaws 48 are closed, the dent 45 turns to the closed ball to prevent the return of the ball or other objects. The mechanism to activate the jaws 48 and the magnet 38 may be an air pressure or oil pressure.
