Abstract

本实用新型是一种用气体对针杆进行冷却降温装置的微波辐射针,解决的是现有微波微创介入治疗过程中使用的微波辐射针的针杆温度较高的问题。它包括针头、中空的针杆、中空的把手、电缆;针杆的前、后端分别与针头、把手相接,电缆穿过把手、针杆与针头相接;与气源相通的通气管穿过把手、针杆而伸入到针杆的前端部;针杆的前端被针头堵塞,把手上设置有出气孔。作为改进,在针头与针杆之间设置一绝热片,以氧气为气源。本实用新型能有效降低针杆的温度,使患者在治疗过程中免受较大的痛苦,同时不影响治疗效果;并且安全可靠,操作简单、方便;结构简单,易于生产制造。

Description

带有气体冷却装置的微波辐射针
                                技术领域
本实用新型涉及一种用于微波治疗的微波辐射针,特别是用气体对针杆进行冷却降温装置的微波辐射针。
                                背景技术
微波辐射针能利用微波对人体某些部位的肿瘤进行烧凝。其方法是在B超或CT引导下,将微波辐射针直接插入肿瘤烧凝,灭杀肿瘤细胞。但由于微波辐射针在治疗过程中针杆发热,温度上升很快,导致患者难以忍受,烫伤针道正常组织,严重影响治疗效果。
                                发明内容
本实用新型解决的是现有微波微创介入治疗过程中使用的微波辐射针的针杆温度较高的问题。
本实用新型所述带有气体冷却装置的微波辐射针,包括针头、中空的针杆、中空的把手、电缆;针杆的前、后端分别与针头、把手相接,电缆穿过把手、针杆与针头相接;与气源相通的通气管穿过把手、针杆而伸入到针杆的前端部;针杆的前端被针头堵塞,把手上设置有出气孔。
将与气源相通的通气管伸入到针杆的前端部,气体从通气管中出来,从针杆前端经中空的针杆内部、针杆后端、把手内部、把手上的出气口流出。在气体流经针杆内部时,将热量带走,使针杆冷却。
为了使针头不随针杆冷却而冷却,以影响微波辐射的烧凝灭杀肿瘤的治疗效果,作为对实用新型的进一步改进,在针头与针杆之间设置一绝热片,该绝热片分别与针头、针杆相接,针杆前端被该绝缘片堵塞。所述绝热片最好以塑料制成。这样使得针头、针杆相隔离,使针杆冷却时,针头不被冷却而降温。
氧气在医院中应用很广,而且经过净化、压缩,因此以氧气为气源时,使用更加方便、安全、可靠。对于上面所述的任一种微波辐射针,最好以氧气为气源。
本实用新型能有效降低针杆的温度,使患者在治疗过程中免受较大的痛苦,同时不影响治疗效果;并且安全可靠,操作简单、方便;结构简单,易于生产制造。
                                附图说明
图1是本实用新型一种实施例的结构示意图
                              具体实施方式
下面结合实施例对本实用新型作进一步说明。
图中,微波辐射针由针头1、针杆2、同轴电缆3、通气管4、绝热片5、把手6、氧气源(图中未示出)等组成。氧气源是由医用氧气钢瓶、减压阀、快速接头、电磁阀、控制开关等组成的氧气供给系统。
针杆2为中空的不锈铜管,外径可选1.6-4mm。中空的针杆2的前端接绝热片5、后端接中空的把手6。绝热片5的另一侧接有针头1;绝热片5把针头、针杆隔开,同时绝热片将针杆的前端堵塞。绝热片5以塑料制成。同轴电缆3穿过把手6、针杆2、绝热片5与针头1相接。
通气管4的一端穿过把手、针杆伸入到针杆2的前端部,其另一端与氧气源相通。
在使用时,针头1插入需治疗的肿瘤组织中,针头发射由同轴电缆3传送的微波能量。氧气从传送制冷氧气的通气管4中出来,从针杆2前端经中空的针杆内部、针杆后端、把手内部、把手上的出气口7流出。在气体流经针杆内部时,将热量带走,使针杆冷却。氧气经过针杆时带走热量,在常温下,针杆温度保持在0℃左右。
