Abstract

一种水射流手术刀,有一个水箱,***水箱的水 管中依次串联着水泵、单向阀、高压蓄能器、截止阀、 压力表、脚踏开关,再连接高压软管和刀头,刀头通过 接头与高压软管相连,刀头顶端镶着有细微小孔的红 宝石喷嘴。这种手术刀作肝、脾、肾等实质器官切割 时,不需阻断血管,大大减少了某些脏器功能的损害; 手术中能达到不出血和少出血的目的,减少了输血 量;手术时间短,使用方便、安全稳定、经济适用。

Description

本实用新型涉及一种医疗手术器械,属于切割用水射流手术刀。
通常,肝脏的切除,较先进的手术刀有激光手术刀、高频电凝手术刀和超声波手术刀。前两种手术刀,是通过热效应来止血的,易造成正常组织的变性和坏死,对疾病治愈不佳;超声波手术刀费用昂贵。
本实用新型的目的,是要提供一种不出血或少出血,较完整地保留组织,尽量使组织不变性无坏死现象的水射流手术刀。
实用新型是这样实现的:有一个水箱,***水箱的水管中依次串联着水泵、单向阀、高压蓄能器、截止阀、压力表、脚踏开关,再连接高压软管和刀头,刀头通过接头与高压软管相连,刀头顶端镶着有细微小孔的红宝石喷咀。
这种水射流手术刀,对切割面附近的组织没有不良影响,作肝、脾、肾等实质器官切割时,不需阻断血管,大大减少了某些脏器功能的损害;手术中能达到不出血和少出血的目的,减少了输血量;手术时间短,使用方便、安全稳定、经济适用。
下面结合附图介绍本实用新型。
图1为本实用新型组装示意图;
图2为本实用新型中手术刀头部分主视图。
参照附图,在装有生理盐水的水箱[1]中,***装有过滤莲蓬头的吸水水管[3],水管上依次连接有水泵[2]、单向阀[4]、高压蓄能器[5]、截止阀[6]、压力表[7]、脚踏开关[8]。上述器件均为市售通用件。脚踏开关后连接高压软管[10],再通过接头[11]连接直径为4mm的钢管刀头[9],刀头外面套着手柄[12]。在刀头顶端镶着一颗红宝石喷咀[13],喷咀用激光打孔加工出一个2-5μa的细微直孔。

Claims (1)

1、一种水射流手术刀,由水箱、水管、水泵、阀门、高压蓄能器等组成,其特征在于:有一个水箱[1],***水箱的水管[3]中依次串联着水泵[2]、单向阀[4]、高压蓄能器[5]、截止阀[6]、压力表[7]、脚踏开关[8],再连接高压软管[10]和刀头[9],刀头通过接头[11]与高压软管相连,刀头顶端镶着有细微小孔的红宝石喷咀[13]。
