Description

一种便于使用的高频电刀 技术领域
本发明属于高频电刀技术领域，具体涉及一种便于使用的高频电刀，其适用于喉内悬雍垂、软腭以及人体内其他组织的切除，特别是耳鼻喉手术中在狭小开口内的组织切除。
背景技术
在对耳鼻喉进行组织切除手术过程中通常采用高频电刀，高频电刀的刀头有多种，例如主切割的切割刀头、主混切的混切刀头、主止血的止血刀头、主电灼、消融的消融刀头，其中，切割刀头的输出功率高至120W，消融刀头输出功率低至40W，而各种刀头采用同样的主机，主机控制其内的高频电路系统向刀头输出高频电波，在手术期间，医生需要更换不同功能的刀头实现不同的操作，更换刀头前需要先调节主机上的输出频率，以避免向刀头输出超出其功能范围的电波造成刀头的损坏，严重时还损害患者的身体，特别是现有的高频电刀的调节过程复杂，对于操作不熟练或者心理素质差的医务人员，在手术的紧张氛围中极易调错主机上的输出功率，这使得手术的效率低，也容易造成医疗事故。
另外，现有高频电刀的开关按钮有两种，一种是安装于主机上的脚踏式，一种是安装于刀柄上的指压式，由于高频电刀的刀头通电后产生高频电波会对误触的人体产生伤害，因此，高频电刀上的开关通常设置成按压开关后导通电路、放开后断开电路的模式，手术期间，需有人持续踩着脚踏式开关或者医务人员持00续按压指压式开关以使刀头与高频电路导通，时间久了，医务人员会因手部长时间保持一个资势以及刀柄过硬而手酸，使手术的效率降低，同时也不利于医务人员的身体健康；另外，在进行喉内悬雍垂切割手术时，现有技术中未有专门的工具，医务人员采用现有工具进行切割过程中总会存在一些刀头不适用的问题。
发明内容
基于以上问题，本发明的目的在于提供一种便于使用的高频电刀。
为了实现以上目的，本发明采用的技术方案为：一种便于使用的高频电刀，包括主机、刀柄、刀头，其中，主机内带有通过控制器进行控制的高频电路系统，刀柄的端部设置刀槽，高频电路系统的正极电缆线穿过刀柄后与刀槽连接，刀槽用于安装刀头并识别刀头型号，所述控制器与刀槽连接并在接收刀头型号后控制高频电路系统向刀槽内的刀头输出适配的高频电波。
本发明提供的便于使用的高频电刀，高频电路系统的负极电缆线接主机外的手术床或手术椅，型号不同的刀头功能不相同，功能不同的刀头所需要的最大输出功率不同，在主机上设定不同型号对应的最大输出功率，当更换刀头时，刀槽识别刀头的型号并反馈给控制器，控制器控制高频电路系统向刀头输出适配功率的高频电波，减少换刀时先在主机上调节输出 频率的操作，控制器还控制高频电路系统向刀头输出的最大功率，避免功率过载损坏刀头或对手术床或手术椅上的病人造成误伤。
优化的，刀头与刀槽连接的一端设置卡槽识别孔，所述刀槽内设置与卡槽识别孔位置对应且可伸缩的弹性卡件，刀柄上设置与弹性卡件适配的传感器，控制器与传感器连接，刀头插入刀槽后，卡槽识别孔挤压对应的弹性卡件，传感器检测到弹性卡件的信号后传输至控制器上，控制器根据信号判断出刀头的型号后控制高频电路系统向刀头输出适配功率的高频电波。
具体的，所述刀槽内壁设置若干孔，弹性卡件为设置于孔内的弹性突球，弹性突球后端与孔壁之间设置弹簧，刀头上的卡槽识别孔与至少一个弹性突球或者弹性突球的组合适配，不同型号刀头上的卡槽识别孔与不同的弹性突球或者弹性突球的组合适配，刀头插入刀槽安装到位后，卡槽识别孔与对应的弹性突球适配以触动传感器，传感器检测到弹性突球的信号后传输至控制器上，控制器根据信号判断出刀头的型号后控制高频电路系统向刀头输出适配功率的高频电波。
更具体的，所述传感器为霍尔传感器，霍尔传感器感应与不同型号的刀头对应的弹性突球的信号，霍尔传感器将此信号转换为电信号通过电缆线传输到控制器上，主机依据此信号可确定刀头的型号并对应的输出适配功率的高频电波，因此可以自动实现更换不同刀头输出不同功率的自动化功能，实现换刀自动化，大大节约手术中更换刀头所用的时间；可以在主机的程序上设置不同型号刀头所适用的最大功率值，当刀头与刀柄连接时，主机上所能调节的最大功率不超过刀头所适配的功率值，避免医护人员在主机上调节的输出功率超过刀头适配的范围，对病人造成伤害，
优化的，所述高频电路系统的电缆线上带有复位开关，所述复位开关设置于刀柄内，所述刀柄中部手持处设置凹槽，凹槽内设置封装有传压介质的弹性密封套，刀柄后部设置滑道，滑道的前端与弹性密封套连通，滑道内设置密封滑块，所述复位开关设置于滑道后端开口处；手握刀柄时，手指自然按压弹性密封套，传压介质推动滑道内的密封滑块触动复位开关，使高频电路系统导通并向刀头输出高频电波。
本发明提供的便于使用的高频电刀，将弹性密封套的传压介质通过密封滑块去触动复位开关，操作人员在自动握住刀柄时，自动通过拇指、食指、中指握在手柄外的弹性密封套上，握紧的同时挤压弹性密封套，从而将传压介质向滑道后部推，进而推动密封滑块触动复位开关以导通电路，这样，医务人员在自然握住高频电刀的同时启动复位开关，从而避免脚踏开关或者持续按压手柄上的开关以导通电路，减轻医护人员的脚酸或手酸情况，且弹性密封套具有一定的弹性，医护人员长期使用过程中也不会因手柄过硬而手酸；另外，弹性密封套设 置于凹槽内，自然放置时，因凹槽壁的阻挡，也不会使弹性密封套变形而误触开关。
优化的，上述高频电刀还包括弹性垫，所述弹性垫嵌设于凹槽内，所述弹性密封套嵌设于弹性垫内并相对于弹性垫凸出，当不需要增加输出频率时，医护人员通过弹性垫手持刀柄进行手术，需要增加输出频率时，手指按压在弹性密封套上以启动复位开关，导通高频电路。
优化的，所述凹槽外部设置可拆卸的保护盖，手术时将保护盖拆下，手术后将保护盖装上以进一步保护弹性密封套，防止弹性密封套变形。
具体的，所述保护盖螺接于刀柄主体后端靠近凹槽处，使用时转动保护盖向后移动至使凹槽露出以便于使用的，手术完成后转动保护盖向前移动至将凹槽盖住以进行保护，从而防止误触。
更进一步的，为了防止误触使弹性密封套变形而引起刀头与电源导通，可以在高频电路导线上增设与复位开关串联的光电开关，光电开关设置于刀柄内位于弹性密封套后部处，使用时，医生手持刀柄按压弹性密封套时，手心自动挡住光电开关，光电开关与密封滑块触动复位开关同时开启以导通电路。
具体的，所述弹性密封套的外部高度小于凹槽的高度，弹性密封套低，在将高频电刀放置于托盘时不会被误触，从而保证不进行手术时，高频电刀不通电。
现有技术中没有专门用于喉部悬雍垂切割的高频电刀，传统的刀头不适用于悬雍垂的切割，使用时必须使病人口部张至最大，而对于一些儿童或者嘴巴较小的特人群，传统刀头没有足够的空间进行切割，使切割难度加大，拖慢手术进程；因此优化的，所述刀头包括切割刀头、混切刀头、止血刀头、消融刀头，所述切割刀头包括连接杆和设置于连接杆前端的刀框，刀框开口处设置切割线，所述卡槽识别孔设置于连接杆的后端；本发明采用的刀头，在进行悬雍垂切除手术时，医护人员用镊子捏住悬雍垂的底部，将刀头伸入口内，从前向后推动刀头即可将悬雍垂切割；混切刀头、止血刀头、消融刀头同样包括用于与刀槽连接的连接杆和设置于连接杆端部的混切部件、止血部件、消融部件。
进一步优化的，所述刀框的后部与连接杆连接且开口向前，所述切割线设置于刀框的开口处，使用时将切割刀头直接伸入病人口内，从前向后推入，即可从前向后切割悬雍垂。
上述推入使用的刀头需要医护人员注意推入的行程，如果推入过多，可能会对病人喉部造成伤害，因此，优化的，所述刀框的左侧与连接杆连接且开口向后，所述切割线设置于刀框的开口处；使用时将切割刀头伸入口内悬雍垂的后部，从后向前拉动刀柄，切割线从后向前切割悬雍垂，这样的结构安全性强，完全不会误伤病人。
进一步优化的，所述切割线与刀框左侧连接的一端低于右侧连接的一端，使得切割线与连接杆之间呈一定的角度，如此，在保证安全性的同时实现高效的悬雍垂切割；更进一步的， 所述切割线与连接杆之间呈20～40°的角度，即切割线与刀框右侧之间呈20～40°的角度，角度过小或过大不便于悬雍垂的快速切割。
具体的，所述滑道后端设置一段弧形槽，所述密封滑块与弧形槽通过转轴连，密封滑块的一端与弧形槽可滑动密封连接，另一端与复位开关的顶部连接；挤压弹性密封套，从而将传压介质向通道内推，传压介质推动密封滑块的一端相对于转轴沿弧形槽转动，另一端推动复位开关以导通电路。
具体的，所述复位开关的顶部通过连杆与密封滑块连接，连杆的两端分别与密封滑块、复位开关可转动连接。
具体的，所述密封滑块的端部设置弧形凸起与复位开关的顶部抵接，密封滑块转动时通过弧形凸起挤压复位开关导通高频电路；可进一步在复位开关的顶部设置与弧形凸起适配的弧形槽，密封滑块转动时，弧形凸起挤压弧形槽以开启复位开关。
本发明的有益效果为：
(1)、本发明提供的便于使用的高频电刀，在主机上设定不同型号对应的最大输出功率，当更换刀头时，刀槽识别刀头的型号并反馈给控制器，控制器控制高频电路系统向刀头输出适配功率的高频电波，减少换刀时先在主机上调节输出频率的操作，提高效率。
(2)、本发明提供的便于使用的高频电刀，进一步将弹性密封套的传压介质通过密封滑块去触动复位开关，操作人员在自动握住刀柄时，自动通过拇指、食指、中指握在手柄外的弹性密封套上，握紧的同时挤压弹性密封套，从而将传压介质向通道内推，进而推动密封滑块触动复位开关以导通电路，这样，医务人员在自然握住高频电刀的同时就启动了刀头的开关，从而避免脚踏开关或者持续按压手柄上的开关以导通电路，减轻医护人员的脚酸或手酸情况。

具体实施方式
下面结合附图对本发明的实施例作进一步详细的说明。
实施例1
如图1所示，本实施例提供一种便于使用的高频电刀，包括主机、刀柄1、刀头，其中，主机内带有通过控制器进行控制的高频电路系统，刀柄1的端部设置刀槽，高频电路系统的正极电缆线穿过刀柄1后与刀槽连接、负极电缆线连接于主机外部的手术床上，刀槽用于安装刀头并识别刀头型号，所述控制器与刀槽连接以接收刀头型号后控制高频电路向刀槽内的刀头输出适配的高频电波；刀头与刀槽连接的一端设置卡槽识别孔，所述刀槽内设置与卡槽识别孔位置对应且可伸缩的弹性卡件，刀柄1上设置与弹性卡件适配的霍尔传感器3，控制器与霍尔传感器3连接；如图2所示，刀槽内壁设置4个孔，弹性卡件为设置于孔内的第一、第二、第三、第四弹性突球4，4个弹性突球4后端与孔壁之间设置弹簧；如图3所示，刀头包括切割刀头2a、混切刀头2b、止血刀头2c、消融刀头2d；主切割的切割刀头2a最大输出功率120W，其上带有与四个弹性突球4位置一一对应的卡槽识别孔；主混切的混切刀头2b，最大输出功率90W，其上带有与第二、三、四弹性突球4位置一一对应的3个卡槽识别孔；主止血的止血刀头2c，最大输出功率60W，其上带有与第三、四弹性突球4位置一一对应的2个卡槽识别孔；主电灼、消融的消融刀头2d，最大输出功率40W，其上带有与第一、四弹性突球4位置一一对应的3个卡槽识别孔；其中，切割刀头2a包括与刀柄1适配的连接杆21a，连接杆21a前端设置刀框22a，刀框22a开口处设置切割线23a，卡槽识别孔设置于连接杆21a后端；
所述高频电路系统的电缆线上带有复位开关5，复位开关5位于刀柄1内，所述刀柄1中部手持处设置凹槽，凹槽内设置封装有传压介质10的弹性密封套6，刀柄1后部设置滑道，如图4所示，滑道后端设置一段弧形槽，滑道的前端与弹性密封套6连通，滑道内设置密封滑块7，复位开关5设置于滑道后端开口处，密封滑块7与弧形槽通过转轴连接，密封滑块7的一端与弧形槽可滑动密封连接，另一端与复位开关5的顶部通过连杆8连接；凹槽外部设置可拆卸的保护盖9，所述保护盖9螺接于刀柄1主体后端靠近凹槽处。
现有技术中没有专门用于喉部悬雍垂11切割的高频电刀，传统的刀头不适用于悬雍垂11的切割，本实施例提供的便于使用的高频电刀，将其用于喉部悬雍垂11的切割时，包括以下步骤：
步骤1、将切割刀头2a的连接杆21a后端插入刀槽内，4个卡槽识别孔与4个弹性突球4适配以触动霍尔传感器3，霍尔传感器3检测到4个弹性突球4的信号后传输至控制器上， 控制器根据信号判断出插入的是切割刀头2a后控制高频电路系统向切割刀头2a输出最高120W的电波；
步骤2、医护人员在主机上调节功率至合适的值，转动刀柄1上的保护盖9向后移动至使凹槽露出，医务人员握住刀柄1时，拇指、食指、中指握在手柄外的弹性密封套6上，自然按压的同时挤压弹性密封套6，将传压介质10向滑道后的弧形槽内推，进而推动密封滑块7的一端转动，另一端通过拉杆触动复位开关5以导通高频电路系统与切割刀头2a，切割线23a上产生高频电波；
步骤3、医护人员用镊子捏住患者悬雍垂11的底部，将切割刀头2a向口内推，通过切割线23a将悬雍垂11多余的部分切除；
步骤4、医护人员松开刀柄1，密封滑块7对复位开关5失去压力，复位开关5复位，高频电路系统断开，拔下切割刀头2a，将止血刀头2c插入刀槽，3个卡槽识别孔与第二、三、四弹性突球4适配以触动霍尔传感器3，霍尔传感器3检测到3个弹性突球4的信号后传输至控制器上，控制器根据信号判断出插入的是止血刀头2c后控制高频电路系统向止血刀头2c输出最高40W的电波；
步骤5、医护人员在主机上调节功率至合适的值，再次握住刀柄1并触动复位开关5以导通高频电路系统与止血刀头2c，医生采用止血刀头对切割处进行止血即可。
上述操作方法同样适用于口内软腭切除以及人体内其他组织的切除，特别是耳鼻喉手术中在狭小开口内的组织切除。
本实施例提供的高频电刀，在主机上设定不同型号对应的最大输出功率，当更换刀头时，刀槽识别刀头的型号并反馈给控制器，控制器控制高频电路系统向刀头输出适配功率的高频电波，减少换刀时先在主机上调节输出频率的操作，提高效率，同时，医务人员在自然握住高频电刀的同时就启动复位开关5，使刀头与高频电路导通，从而避免采用脚踏开关或者指压式开关时医护人员的脚酸或手酸情况，且弹性密封套6具有一定的弹性，结合其内传压介质10的流动性，医护人员长期使用过程中也不会因手柄过硬而手酸；另外，弹性密封套6设置于凹槽内，自然放置时，因凹槽壁的阻挡，也不会使弹性密封套6变形而误触开关，手术完成后转动保护盖9向前移动至将凹槽盖住以进行保护，从而防止误触。
实施例2
本实施例对实施例1中的密封滑块7与复位开关5的连接结构进行改进，如图5所示，密封滑块7的端部设置弧形凸起与复位开关5的顶部抵接，复位开关5的顶部设置与弧形凸起适配的弧形槽，密封滑块7转动时，弧形凸起挤压弧形槽以开启复位开关5，这种抵接的传动结构更加灵活方便。
实施例3
本实施例对实施例1的切割刀头2a结构进行改进，实施例1的切割刀头2a需要医护人员注意推入的行程，如果推入过多，可能会对病人喉部造成伤害，因此，如图6所示，本实施例将刀框22a的左侧与连接杆21a连接且开口向后，所述切割线23a设置于刀框22a的开口处；使用时将切割刀头2a伸入口内悬雍垂11的后部，从后向前拉动刀柄1，切割线23a从后向前切割悬雍垂11，这样的结构安全性强，完全不会误伤病人。
实施例4
本实施例对实施例3的切割刀头2a结构进行改进，如图7所示，切割线23a与刀框22a左侧连接的一端低于右侧连接的一端，使得切割线23a与连接杆21a之间呈一定的角度，如此，在保证安全性的同时实现高效的悬雍垂11切割；切割线23a与连接杆21a之间呈20～40°的角度，即切割线23a与刀框22a右侧之间呈20～40°的角度，角度过小或过大不便于悬雍垂11的快速切割，本实施例中角度为30°。
本发明的上述实施例仅仅是为说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其他不同形式的变化和变动。这里无法对所有的实施方式予以穷举。凡是属于本发明的技术方案所引申出的显而易见的变化或变动仍处于本发明的保护范围之列。
