Abstract
The invention relates to a medical endoscope (1) that comprises a proximal end piece (3) and an optical system (4) that can be inserted up to a proximal eyepiece (5). A spring-loaded locking device is configured in the end piece and engages in a groove (8) of a pin (7) in a locking manner. Said pin is provided with a tip (9), distally projects from the eyepiece and can be inserted in the groove. A slide (12a) is disposed in a shaft (11) that extends in the end piece (3) and can be actuated from the shaft end. Said slide is coupled to one or more blades (15a) in such a manner that it lifts them off the pin when the device is actuated, the blades being slideable cross-wise to the pin in the end piece and being pressed against the pin under the action of a spring.
Claims7
A medical endoscope (1) comprising a proximal terminal segment (3) and an optics (4) which may be inserted as far as a proximal ocular segment (5), further comprising a spring-loaded locking system configured in the terminal segment for the purpose of locking into a channel (8) of a pin (7) which is fitted with a tip (9) and which projects distally from the ocular segment, characterized in that
- a slider (12a) is supported in a duct (11) extending in the terminal segment (3) and may be actuated from an end of said duct, said slider (12a) being linked in such manner with one or several blade elements (15a) which are displaceably supported in the terminal segment transversely to the pin and resiliently rest against the pin in such manner that said slider upon being actuated shall lift said blade elements (15a) off the pin.
