Abstract

The front end cover of an endoscope is molded by injecting resin into a mold for molding. The front end cover is assembled on the front end member of the insertion portion of the endoscope and is provided with a lifting platform to cover the front end member. At least part of it has an opening that exposes the space housing the lifting platform to the outside, and the front end cover of the endoscope has a thin-walled portion, one end of which is connected to the peripheral edge of the opening, and extends linearly; and two resin injection gate marks are arranged to separate the thin wall portion.

Description

technical field [0001] The present invention relates to a distal end cover of an endoscope attached to a distal end member constituting a distal end portion of an insertion portion of an endoscope and provided with a lifting platform, and a molding die for molding the same. Background technique [0002] As one of medical endoscopes, there is a so-called duodenal endoscope, which is a side-view endoscope (hereinafter referred to as an endoscope) in which an illumination lens and an objective lens are arranged on the front end side of an insertion portion. mirror). A treatment instrument channel and a lifting device are arranged in the endoscope. [0003] In the treatment instrument channel, treatment instruments such as contrast tubes, basket catheters, and balloon catheters are inserted. The treatment instrument passing through the treatment instrument channel is led out from the front opening provided on the front part, and the leading direction is switched to a desired d...
