Abstract: A safety needle system includes a needle and a safety device. The safety device includes a housing having a channel. A stem of the needle can pass through the channel. The housing can slide over the stem such that the needle is moveable relative to the housing between a first position, in which the needle tip protrudes from the housing, and a second position, in which the needle tip is inside the channel. A closing device can close a distal opening of the housing when the needle is in the second position. The closing device includes a protection flap that closes the distal opening when the protection flap is in a first flap position. The closing device also includes a securing element configured to block movement or deformation of the protection flap out of the first flap position towards the inside of the channel.

Abstract: A medical instrument includes at least a first instrument shank and a second instrument shank that can be moved in relation to each other. The first instrument shank is a male instrument shank with a male bearing section. The second instrument shank is a female instrument shank with a female bearing section that includes a through-opening. The first instrument shank is arranged on the second instrument shank by the male bearing section engaging through the through-opening of the female bearing section. The instrument is produced by an additive manufacturing method.

Abstract: The invention relates to a medical circulation detent device, comprising at least one circulation body and a latching element. The at least one circulation body comprising a restricted guide and at least one latching receptacle for the latching element. The latching element is guidable through the restricted guide from an unlatched position to a latched position at a first side of the at least one latching receptacle into the latter, and at a second side of the at least one latching receptacle from the latched position to an unlatched position again. An operative element is coupled to the latching element via a coupling element. A thermal actuating element is operatively connected to the latching element and transferable due to temperature from a first state to a second state and vice versa in order to move the operative element. The invention also relates to a medical sterilization container.
