Abstract
A medical puncturing device and a system comprising medical apparatuses configured to be assembled into the medical puncturing device. The device or system comprises: a syringe barrel (1) comprising a distal closed end and a proximal open end; an elastic movement unit comprising an actuation member (2) and a floating seal (3) inside the syringe barrel (1), where the actuation member (2) and a floating seal (3) are capable of forming an elastic connection such that the actuation member (2) and floating seal (3) are capable of moving forward and backward relative to one another; a hollow puncture needle (6) fixedly connected to the actuation member (2) and proximal to the floating seal (3), where the hollow puncture needle (6) comprises a needle distal opening (6a) and a needle body opening (6b); and a flowable composition lumen (7) enclosed by the syringe barrel distal closed end, an inner wall of the syringe barrel, and the floating seal (3). The device or system is configured to advance the hollow puncture needle (6) distally. Prior to use, the needle distal opening (6a) can be proximal to the floating seal (3), within the floating seal (3), between the floating seal (3) and a dis…
