Abstract

A medical endoscope is an instrument having an elongate, tubular shaft. The instrument is commonly provided with a flushing device. The flushing liquid can be guided through corresponding separate liquid channels. In order to be able to control the flow of the liquid, the liquid channels have a stopcock. The stopcocks here are of complex construction, and for this reason both the production thereof and the cleaning thereof are complicated. The invention includes a stopcock and also a housing and a method for producing the housing, by way of which the production and the cleaning of the housing are simplified. This is achieved in that a housing and at least one spring element for form-fitting fixing of a plug in a position in the interior space of the housing are manufactured integrally from a single part, that is to say in one part.

Claims12

Dependent claims

A housing of a stopcock for producing and breaking a fluidic connection between at least two connection parts, the housing having at least two spring elements, and having an interior space in which a plug of the stopcock can be mounted in a rotatable manner, wherein:

the at least two spring elements are provided for form-fitting fixing of a position of the plug in the interior space of the housing, wherein the housing and at least one spring element is manufactured integrally from one part;
the at least two spring elements are formed from a housing wall of the housing;
the at least two spring elements are formed parallel to a longitudinal axis of the housing as an extension of the housing wall and forms a spring load perpendicular to the longitudinal axis;
a wedge-shaped recess is formed between each of the at least two spring elements in the housing wall;
and
openings of the wedge-shaped recesses are oriented towards a bottom side of the housing.
