US 2026/0174456 A1 · ADAPTER DEVICE, DISASSEMBLABLE MEDICAL SHAFT INSTRUMENT AND METHOD FOR CLEANING THE DISASSEMBLABLE MEDICAL SHAFT INSTRUMENT AND ASSEMBLY METHOD

Abstract

The present invention provides an adapter device and a disassemblable medical shaft instrument equipped therewith, a method for cleaning the disassemblable medical shaft instrument and a method for assembling the adapter device to provide the disassemblable medical shaft instrument. The adapter device (10) is designed for arrangement in a disassemblable medical shaft instrument (1) comprising a shaft (2), a transmission rod (40) that can move in the shaft (2) and a handling apparatus (3) comprising a housing part (30) and an actuating part (31) which is movable relative to the housing part (30). The adapter device (10) has a transmission adapter (5) designed for releasably coupling to the actuating part (31) and to the transmission rod (40), and an adapter sleeve (6) designed for releasably coupling to the shaft (2) and the housing part (30). The adapter sleeve (6) has an axial bore (64, 65, 66, 67) in which a distal coupling portion (52) of the transmission adapter (5) is arranged, and wherein the transmission adapter (5) is movable in a translational manner relative to the adapter sleeve (6). According to the invention, a proximal portion (67) of the axial bore (64, 65, 66, 67) of the adapter sleeve (6) is frustoconical and widens toward the proximal end of the axial bore (64, 65, 66, 67), wherein the frustoconical proximal portion (67) is designed to releasably receive a conical nozzle (21) of a flushing device (20).
