Title: Forceps cock for endoscope
Inventor: AKIBA HARUO
IPC: A61B1/00
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To effectively prevent reversed leakage by arranging a counterflow easing means between a channel inlet and the outside of a forceps port member to reduce the internal air pressure down to a value between the internal air pressure and an external air pressure while storing a fluid matter reversed from a channel for a treating device. SOLUTION: In a state where a treating device is completely inserted into a channel for the treating device, the treating device is clamped from the perimeter thereof by an insertion hole 25m of the body 25 of a forceps cock to once block a mixed fluid matter of a humor or the like and air reversed in place. But when a difference is large between the air pressure in a lumen as the cause of the reversion and the atmospheric pressure outside the forceps cock, the fluid matter gradually leaks out into an inner chamber 25h from between the insertion hole 25m and the treating device. But the capacity of the inner chamber 25h is made larger relatively as compared with a gap of the insertion hole 25m to make an expanded space, thus causing the fluid matter to be injected into the inner chamber 25h thereby reducing the pressure of the fluid matter.

Abstract: PURPOSE:To decrease the linking jobs of an post-process and to increase the assembling speed by decreasing the number of pending symbols to be processed in the post-process. CONSTITUTION:An assembler of each module extracts a character string and its value of a local symbol defined in a module as well as a character string of a public symbol defined in another module that is referred to in the relevant module and stores these extracted character strings and values into a symbol table 57a set in a main memory 57.

At the same time, the value of the public symbol whose character string only is stored in the table 56b is searched out of the table 56b for substitution. As a result, the number of pending symbols can be decreased and a high-speed assembling job is attained.
