<p style="line-height: 21.3333px;">目前超声设备多数配有穿刺架,可配套安装于线阵、凸阵、相控阵、腔内探头等各种类型探头上。附加穿刺架的普通探头,将穿刺架安装在探头长轴的一端或侧方,引导穿刺针进入穿刺目标,不但扩大了普通扫描探头的效用,也节省了购买专用穿刺探头(注:中央凹槽型穿刺探头)的费用。探头上附加穿刺架,保证穿刺针沿预定的穿刺角度与深度进入扫描平面,刺中目标,并可实时监视穿刺全过程,提高了穿刺的准确性和可靠性。一般穿刺架设计需要考虑以下因素: </p><p style="line-height: 21.3333px;">(1) 适宜的针槽长度,以保证穿刺针引导过程中的稳定性,避免偏移,如图6,经方医疗为<span style="line-height: 21.3333px;">GE医疗3CRF腹部探头设计的穿刺架,箭头所指即为针槽长度。</span></p><p style="line-height: 21.3333px;"><br /></p><p style="line-height: 21.3333px;"><img data-s="300,640" data-type="png" src="http://mmbiz.qpic.cn/mmbiz_png/dx3KibwtDhvcE2dNZZsDGo0jwFuF60w0crB19ps4K6t8HklNFI3GGh5BnbgpnNLd21jbFuFkP1wicnCq8dg6jTgA/0?wx_fmt=png" data-ratio="0.6467289719626168" data-w="535" /><br /></p><p style="line-height: 21.3333px;"><br /></p><p style="line-height: 21.3333px;">(2) 针槽口径须能适合不同规格的穿刺针,目前市面上的针槽装置主要以下几种: </p><p style="line-height: 21.3333px;">A) 穿刺架的针槽口径可按医生的需要进行调节。如图7,经方医疗为西门子4V1相控阵探头设计的整体式穿刺架,针槽可以通过螺钉任意调节,可适配22‐14G任意针型。这种方案对穿刺针的适用性相对较广,包括15G、17G、19G等不常用的针型都可以匹配,对15.5G之类特殊的射频消融针或微波消融针都可以正常使用,同时整体式的设计方案避免了配件多容易丢失的情况。 </p><p style="line-height: 21.3333px;"><br /></p><p style="line-height: 21.3333px;"><img data-s="300,640" data-type="png" src="http://mmbiz.qpic.cn/mmbiz_png/dx3KibwtDhvcE2dNZZsDGo0jwFuF60w0cGSNe7ywBWxr4dqzeNBsYR29J77SIRt4TaNyMxwQiahadVagiao7EQHcw/0?wx_fmt=png" data-ratio="0.8366890380313199" data-w="447" /><br /></p><p style="line-height: 21.3333px;">B) 穿刺引导支架附有不同规格的导槽,使用不同规格的穿刺针,应选用相应规格的导槽装入穿刺引导支架。此型优点是使用方便,更换容易;缺点是配件多,容易在消毒灭菌和转运过程中丢失。如图8所示,经方医疗为迈瑞C5‐2腹部探头设计的穿刺架,根据客户的需求可以有14~22G多种型号的导槽可以选择。</p><p style="line-height: 21.3333px;"><img data-s="300,640" data-type="png" src="http://mmbiz.qpic.cn/mmbiz_png/dx3KibwtDhvcE2dNZZsDGo0jwFuF60w0cOOXc4nMe4n1yK9vkiaxwckRDRZyoE50GqiapTQeJUBQjMWkKRz7kvpuA/0?wx_fmt=png" data-ratio="0.7762645914396887" data-w="514" /><br />C) 穿刺引导支架的针槽盘含多条不同规格的针槽,针槽盘可根据医生的要求旋转更换,确定好后将穿刺针插入相应规格的针槽中,如图9为经方医疗为GE 3CRF小凸探头设计的带针槽盘的穿刺架。</p><p style="line-height: 21.3333px;"><br /></p><p style="line-height: 21.3333px;"><img data-s="300,640" data-type="png" src="http://mmbiz.qpic.cn/mmbiz_png/dx3KibwtDhvcE2dNZZsDGo0jwFuF60w0ct6oY9awm7gcbsB35MLhl9gXAMGB27CCuibHW6lwtmAkf6Vc9fZuxEdw/0?wx_fmt=png" data-ratio="0.6818181818181818" data-w="550" /><br />(3) 应具有角度控制调节装置:有两类,一类是固定式,即只有一种进针角度,如图10,经方医疗为Sonosite大凸C60x探头开发的单角度穿刺架;另一类是可调式,即可根据穿刺目标的深度,选择不同角度进针,如图11,经方医疗为ESAOTE CA541腹部探头设计开发的穿刺架,有3个角度可以调节,分别为:15度、25度和35度。 从临床使用角度上来看,多角度增加了穿刺深度的适用性,能满足不同深度穿刺目标位的需求,该临床需求需要超声厂家在穿刺引导线的角度设计过程中加以考虑。</p><p style="line-height: 21.3333px;"><br /></p><p style="line-height: 21.3333px;"><img data-s="300,640" data-type="png" src="http://mmbiz.qpic.cn/mmbiz_png/dx3KibwtDhvcE2dNZZsDGo0jwFuF60w0cVlrqn7QgL7KMm34Jvz95htDXiavicxzblYNpfaTgAjZ1ibKPaxdR3QA6g/0?wx_fmt=png" data-ratio="0.4685212298682284" data-w="683" /><br />(4) 穿刺针要求能在穿刺架上灵活方便地拆卸:在治疗过程中,穿刺针进入目标位后,经常需要在人体内停留一段时间,例如做囊肿的抽吸及酒精注射治疗、射频消融或微波消融、穿刺置管等,在这种情况下,安装了穿刺架的探头一般可以暂时挪开,因此穿刺针能与穿刺架灵活方便的分离非常重要,特别是对于安放测温针和电极。如图12,经方医疗为TOSHIBA PVT‐375BT腹部探头设计的穿刺架,医生在需要的时候只需要一个动作(按压一下手柄),就能实现穿刺针和穿刺架的分离,灵活方便。</p><p style="line-height: 21.3333px;"><br /></p><p style="line-height: 21.3333px;"><img data-s="300,640" data-type="png" src="http://mmbiz.qpic.cn/mmbiz_png/dx3KibwtDhvcE2dNZZsDGo0jwFuF60w0cBAyictEk9XxMzGb4RccXYia5JX7xjQbJhicxOwnFmva9FdrWUb5CL9B3g/0?wx_fmt=png" data-ratio="0.8161209068010076" data-w="397" /></p><p><br /></p><p style="max-width: 100%;
