【技术实现步骤摘要】
新型医用电刀
:本技术涉及医用手术器械
,具体的说是一种手术视野清晰且能够避免损坏周围正常组织的新型医用电刀。
技术介绍
:众所周知,电刀是一种常用的外科手术器械,它通过有效电极尖端产生高频电压电流,在于肌体组织接触时,对组织进行加热,从而实现对肌体组织的分离和凝固,达到切割和止血的目的。现阶段高频电刀在手术应用过程中存在手术视野差的问题,即使在先进的手术无影灯照明下,尤其当采用高频电刀进行深部电刀操作时,难以达到满意的手术视野。除此之外,现有的电刀刀柄是直型,不能改变切割方向,在对软组织进行切割时,由于相关部位形状和切口的位置所限,直电刀头不易到达电切的位置,给手术带来不便。
技术实现思路
:本技术针对现有技术中存在的缺点和不足,提出了一种手术视野清晰且能够避免损坏周围正常组织的新型医用电刀。本技术可以通过以下措施达到:一种新型医用电刀,设有持柄和电刀头,其特征在于电刀头经连接头与持柄相连接,电刀头具有直型主体,直型主体前端设有弯折部,直型主体与弯折部的夹角范围为140°-150°,所述持柄设有中空管状壳体,壳体内设有高频电刀控制电路,壳体前端设有连接螺纹,连接头上开设用于固定电刀头的固定孔,电刀头的直型主体的后端穿过固定孔与壳体内的高频电刀控制电路相连接,连接头后端设有螺纹,连接头的外壁上设有筋肋,照明器套设在连接头上,所述照明器设有套式主体、LED光源、光源开关控制电路、电源、光源透镜,其中LED光源设置在套式主体的前端,光源透镜呈罩状固定于LED光源外部,光源开关控制电路串接在LED光源和电源之间;套式主体上设有与连接头外壁筋肋相配合的凹槽。本技 ...
