Split type sternal puncture needle handle assembly and split type sternal puncture needle

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.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a handle assembly of a split-type sternal puncture needle and a split-type sternal puncture needle. Background technique [0002] Intraosseous infusion is an advanced first aid measure. When venipuncture cannot be established, intraosseous puncture can quickly establish an intraosseous infusion channel and improve the rescue rate of emergency personnel at the emergency scene. The existing split handle sternal puncture needle generally includes The handle assembly and the base assembly, wherein the handle assembly is reusable, and the base assembly has a main needle and an auxiliary needle for puncturing, so it can only be used for one time, and the base assembly needs to be assembled on the handle assembly when puncturing, so how to To provide a connection structure that facilitates the connection and disassembly of the base component and the handle component has beco...
