Title: MEDICAL, ESPECIALLY SURGICAL, INSTRUMENT
Abstract:
The invention relates to a medical, especially surgical, instrument, comprising two parts (2, 3) which can be joined to each other by means of a coupling, a coupling sleeve (7) which is joined to one of the two parts (3) of said instrument, and a coupling shank (6) which is formed on the other part (2) of the instrument and can be fixed inside the coupling sleeve (7). The coupling sleeve (7) and the coupling shank (6) can be joined to each other in a non-positive fit. The coupling element (13) can be moved in an essentially axial manner only and the coupling has only one spring element (14). In order to produce a simple cost-effective medical instrument, the coupling element (13) is brought into contact with oblique contact members (17) of the coupling sleeve (7) and the coupling shank (6) and the angle (α) formed between the center axis of the coupling sleeve (7) and the oblique contact member (17) of the coupling sleeve (7) is greater than the angle (β) formed between the center axis of the coupling shank (6) and the oblique contact member (17) of the coupling shank (6).
