用于内窥镜的一次性帽

Disposable cap for endoscope

Abstract

一种可分离地连接到内窥镜的光学头的帽具有管状壳体,该管状壳体通过由半透明塑料注射成型制造。壳体包括后开口端、由前端面封闭的前端以及用于防止光学头的取景器观察到寄生反射的防眩环。所述防眩环嵌在帽的前端面内,所述光学头可通过前端面的由防眩环限界的一部分观察感兴趣的目标。防眩环设有至少一个间断区域,在帽的注射成型过程中塑料可流过该至少一个间断区域。
A cap, which is detachably connectable to an optical head of an endoscope, has a tubular housing, which is manufactured by injection molding from translucent plastic material. The housing includes a rear open end and a frontal end closed by a frontal face and an antiglare ring for preventing a viewer of the optical head from viewing parasitic reflections. The antiglare ring is embedded within the frontal face of the cap and said optical head can view an object of interest through a portion of the frontal face which is confined by the antiglare ring. The antiglare ring is provided with at least one discontinuity region through which the plastic material can flow during injection molding of the cap.
