The invention discloses a device and method for detecting runoff producing positions on a karst slope surface. The two ends of a PVC pipe are arranged in tee joints in a sleeved mode, the PVC pipe is filled with a thin gauze element, a water inlet hole is drilled in the wall of the PVC pipe, two ends of the tee joints are arranged in water storage pipes with sealed ends and pipe caps respectively in a sleeved mode, and a water guide pipe with a pipe plug at the upper end is inserted into each pipe cap and extends to the lower end of the corresponding water storage pipe. Based on slope surface point selection, the device is buried according to slope positions and types of heterogeneous ecological niches; after each rainfall, the runoff producing situation is checked, a water sample is collected, and basic water chemical indexes are measured; the runoff producing possibility of each point on the slope surface in a hydrologic year and the space-time distribution of the water chemical indexes are comprehensively analyzed, and finally judgment on the runoff producing positions on the slope surface is finished. The device for detecting the runoff producing positions on the karst slope surface is simple to manufacture, small in investment, and convenient and rapid to install, solves the problems occurring when a traditional research method is used for detecting the runoff producing positions on the karst slope surface and other areas with discontinuous earth covers, and can provide a technical means for the aspects of reasonable utilization of limited water resources, reasonable distribution of land utilization, vegetation recovery strategies and the like in the areas.

An implant ( 1 ) for mounting a connection pin ( 17 ) of a medical device shows a longitudinal axis ( 9 ), a distal end ( 3 ) and a proximal end ( 4 ), from which extends a mounting recess ( 10 ) for the connection pin ( 17 ) in the direction of the longitudinal axis ( 9 ) into the inside of the implant ( 1 ). The outer generated surface of the implant ( 1 ) can be connected in a non-positive or positive manner with the inner generated surface of a mounting hole in a bone of a human or animal body. The connection pin ( 17 ), which is adapted to the mounting recess ( 10 ), can be connected in a non-positive or positive manner with the inner generated surface of the mounting recess ( 10 ). In order to enable rapid creation and similarly rapid breaking of the connection between the medical device and the implant ( 1 ), it is proposed that the inner generated surface of the mounting recess ( 10 ) should be provided with at least one depression extending perpendicular to the longitudinal axis ( 9 ) of the implant ( 1 ) and constituting an undercut, with which an outwardly protruding projection ( 20 a) of an elastic clip device ( 20 ) of the connection pin ( 17 ) can be radially engaged.
