Abstract:
A stopcock for controlling ducts in medical endoscopes passing flux media, comprising a housing (1) made of a hard material and rotatably receiving a conical plug (4) in a conical seat (3) crossed by a duct (2), said housing subtending, in the direction of an axis of rotation and beyond a larger opening of the conical seat (3), a bearing collar (6) that supports a rotary body (9) that is rotatable about the axis of rotation, said rotary body being fitted outside said housing with a handle (10) and being rotationally coupled with the plug, said rotary body being axially displaceable and biased by a spring relative to said plug and further being fitted with a radially elastic detent device (16), which in the assembled state of said stopcock, is configured inside the housing, said rotary body (9) by operation of said detent device (16) acting in a locking manner against the spring action on said bearing collar (6), wherein the rotary body (9) is fitted with prefabricated rupture site (15) that, following deliberate rupture, exposes the detent device (16).
