Abstract

The invention discloses a split type sternal puncture needle handle assembly and a split type sternal puncture needle. The handle assembly comprises a sleeve, a percussion shaft, an energy storage mechanism, a trigger mechanism and a quick-changing assembly, wherein the percussion shaft and the sleeve are in sliding fit; the percussion shaft stretches into one end of an inner cavity of the sleeve;the energy storage mechanism is arranged between the percussion shaft and the sleeve; the trigger mechanism comprises a percussion separation blade, a reset piece and a trigger plate; the percussionseparation blade stretches out to lock the percussion shaft under the action of the reset piece, so that the energy storage mechanism is at an energy storage state; the trigger plate and the percussion separation blade can be matched in a contact way, so that the percussion separation blade is retracted to release the percussion shaft; the quick-changing assembly comprises an annular clamping sleeve arranged at an opening end of the sleeve; multiple spring pins are arranged on the annular clamping sleeve; and the spring pins are matched with a pin groove on a percussion base, so that the quick-changing assembly and the percussion base are connected in a clamping way. Through the quick-changing assembly, a base assembly can be quickly changed so as to calmly deal with large-scale group damage, the handle assembly can be reused, the waste is reduced, and the use cost is reduced.
