摘要：
A medical device comprising an outer housing (400) having a first wall (401) defining a first passage (402) with proximal and distal ends. A retraction housing (412) is slidably received in the first passage (402), the retraction housing (412) having proximal and distal ends and a wall with an interior surface wall defining a helical path (421). Part of the device includes a carriage (422) for releasably receiving a medical sharp (423), the carriage (422) slidably received in the distal end of the retraction housing (412). A latch means (428) is present for retaining the carriage (422) in a first position in the retraction housing (412). A follower (432) is connected to the carriage (422) and engaged with the helical path (421). A stored energy device (434) is connected to the follower (432) and the carriage (422). An actuation means (419) is operable to move the retraction housing (412) towards the distal end of the first passage (402), thereby to release the latch means (428) such that the stored energy device (434) is operable to drive the follower (432) along the helical path (421) and to retract the carriage (422) towards the proximal end of the retraction housing (412).提供一種醫療元件，該醫療元件包含外殼體(400)，該外殼體(400)具有第一壁(401)，該第一壁(401)界定第一通道(402)，該第一通道(402)具有近端及遠端。回縮殼體(412)滑動地收納於第一通道(402)中，回縮殼體(412)具有近端及遠端及壁，其中，內表面壁界定螺旋路徑(421)。部分元件包括托架(422)，該托架(422)用於可釋放地收納醫療銳器(423)，托架(422)滑動地收納於回縮殼體(412)之遠端中。存在閂鎖構件(428)用於將托架(422)保持在回縮殼體(412)中之第一位置中。從動件(432)連接至托架(422)且該從動件與螺旋路徑(421)嚙合。儲能元件(434)連接至從動件(432)及托架(422)。致動構件(419)可操作以將回縮殼體(412)朝向第一通道(402)之遠端移動，從而釋放閂鎖構件(428)，以使得儲能元件(434)可操作以沿螺旋路徑(421)驅動從動件(432)且以朝向回縮殼體(412)之近端回縮托架(422)。
