BIOPSY FORCEPS FOR ENDOSCOPE

摘要

The present invention relates to biopsy forceps for an endoscope. The biopsy forceps for an endoscope comprise: forceps that are opened and closed so as to collect tissues or discharge collected tissues; a wire for opening and closing the forceps; a handle assembly controlled by an operator so as to operate the wire and to open or close the forceps thereby; and a locking device equipped in the handle assembly so as to lock the operation of the handle assembly so that the forceps are maintained in a closed state. The locking device uses, for example, a plate spring or a rack gear and pinion gear. Once tissues are collected in the forceps, the locking device locks the operation of the handle assembly so that the forceps are maintained in a closed state. By means of the present invention, the forceps are locked to be maintained in an opened state while collecting tissues so that the biopsy forceps can be handled easily, production costs for the biopsy forceps is reduced, and reuse of the biopsy forceps can be prevented.
