Abstract
In order to flush away local bleeding during surgery with a medical instrument, the instruments are commonly provided with a flushing device. In order to be able to control an inflow and outflow of a flushing liquid, the instruments have a stopcock. In order to achieve the sealing action of the stopcock, the plugs of the stopcock have to be formed with a very high degree of precision. The known production processes for such plugs are very cumbersome and cost-intensive. This provides a plug for a stopcock and a stopcock and a method for producing a plug, by way of which the stated problem is eliminated. This is achieved in that a plug, with a grip part and a cone part, is formed in one part and can be produced in a single process step.
Claims12
Plug for a stopcock for producing and breaking a fluidic connection between at least two connection parts, wherein the plug can be mounted in a rotatable manner in an interior space of a housing of the stopcock and has, one behind the other in the direction of an axis of rotation, a cone part, which has a cone surface, and a grip part, which has a grip, wherein the cone part has a bore perpendicularly to the axis of rotation, and wherein the cone surface has webs which can be brought into sealing connection with an inner surface of the interior space of the housing, wherein the plug, with the cone part and the grip part, is formed in one part.
