技术领域technical field
本发明涉及医疗器械领域，更具体涉及一种超声镊，适用于切割甲状腺等开放的精细手术，达到切割及快速凝血的效果。The invention relates to the field of medical devices, and more specifically relates to an ultrasonic tweezers, which are suitable for open fine operations such as cutting the thyroid gland, and achieve cutting and rapid coagulation effects.
背景技术Background technique
在开放式手术中，冷刀和电极电刀常常用于切割分离组织，冷刀在切割分离组织时会大量出血，单极电刀在切割分离组织及凝血时需要在病人身上粘贴负极板，电刀作用在病灶处的电流通过人体传到负极板，距离远，凝血差，并且有结痂，烟雾。本发明超声镊利用超声波作为能量，无需极板，且可快速凝血。除此之外，在切割甲状腺的手术中，至少需要超声剪和双极电凝镊两种手术刀具，而本发明可以同时兼具以上两种手术刀具的功能。In open surgery, cold knife and electrode electric knife are often used to cut and separate tissue. Cold knife will cause a lot of bleeding when cutting and separating tissue. Monopolar electric knife needs to paste negative plate on patient when cutting and coagulating tissue. The current that the knife acts on the lesion is transmitted to the negative plate through the human body. The distance is long, the blood coagulation is poor, and there are scabs and smoke. The ultrasonic tweezers of the present invention use ultrasonic waves as energy, do not need polar plates, and can rapidly coagulate blood. In addition, in the operation of cutting the thyroid gland, at least two kinds of surgical knives, ultrasonic scissors and bipolar electric coagulation forceps, are needed, and the present invention can simultaneously have the functions of the above two surgical knives.

具体实施方式Detailed ways
下面结合附图对本发明超声镊进一步解释。The ultrasonic tweezers of the present invention will be further explained below in conjunction with the accompanying drawings.
如图1，一种超声镊，包括刀杆1、刀管2、壳体5和单镊片7、，所述的刀管2设置在刀杆1的外周以包裹刀杆的中部，刀管2套在刀杆1上且皆有一个孔，刀管2和刀杆1通过与轴向垂直的销4固定在壳体5中，刀杆1一端为手术操作端，刀杆1的另一端与换能器6螺纹连接，换能器6通过导电环和线路与主机相连，从而实现主机对刀杆1输出能量的控制，使医生可以通过主机上的脚踏开关调整切割方式和速度，主机上的脚踏开关可以控制输出能量的大小），壳体5尾部设置旋转轴9，旋转轴9插入单镊片7一端的通孔内并绕旋转轴9在一定角度范围内旋转，单镊片7与壳体5之间设有弹簧片8，弹簧片8在自然弹起状态下，单镊片7与刀杆1张开成一定角度，弹簧片8在按压压缩状态下，单镊片7的另一端与刀杆1手术操作端闭合在一起。As shown in Fig. 1, a kind of ultrasonic tweezers comprises cutter bar 1, cutter tube 2, housing 5 and single tweezers sheet 7, and described cutter tube 2 is arranged on the outer periphery of cutter bar 1 to wrap the middle part of cutter bar, and cutter tube 2 are set on the knife bar 1 and each has a hole. The knife tube 2 and the knife bar 1 are fixed in the housing 5 through the pin 4 perpendicular to the axial direction. One end of the knife bar 1 is the operation end, and the other end of the knife bar 1 is It is threadedly connected with the transducer 6, and the transducer 6 is connected to the host through a conductive ring and a wire, so that the host can control the output energy of the cutter bar 1, so that the doctor can adjust the cutting method and speed through the foot switch on the host. The foot switch on the top can control the size of the output energy), the tail of the housing 5 is provided with a rotation axis 9, the rotation axis 9 is inserted into the through hole at one end of the single tweezers 7 and rotates around the rotation axis 9 within a certain angle range, the single tweezers 7 and the housing 5 are provided with a spring piece 8, and the spring piece 8 is in a state of natural bounce, and the single tweezers piece 7 is opened at a certain angle with the knife bar 1, and the spring piece 8 is pressed and compressed, and the other side of the single tweezers piece 7 One end is closed together with the operation operation end of the knife rod 1 .
所述的弹簧片8的一端固定在单镊片7上，另一端为自由端，按压单镊片7时自由端在壳体5上滑动。One end of the spring sheet 8 is fixed on the single tweezers sheet 7, and the other end is a free end, and the free end slides on the housing 5 when the single tweezers sheet 7 is pressed.
依据壳体5的形状，单镊片7被折弯成一定的形状，保证单镊片7的前端在被按压时与刀杆1接触紧密，保证切割效果。单镊片7的手术操作端相对于单镊片7的中部向下靠近刀杆1。According to the shape of the housing 5, the single tweezers 7 is bent into a certain shape, so as to ensure that the front end of the single tweezers 7 is in close contact with the cutter bar 1 when pressed, thereby ensuring the cutting effect. The surgical operation end of the single tweezers sheet 7 is close to the cutter bar 1 downwards relative to the middle part of the single tweezers sheet 7 .
所述的壳体5为塑料壳，壳体5为两个半壳通过封口盖3合拢为整体，封口盖3为环形，两个半壳闭合在一起后插入环形封口盖内固定。Described housing 5 is a plastic shell, and housing 5 is two half-shells closed into a whole by sealing cap 3, and sealing cap 3 is ring-shaped, and after two half-shells are closed together, insert in the ring-shaped sealing cap and fix.
弹簧片8在自然状态下可保证单镊片7与刀杆1成一定角度，与普通单镊片外形几乎无异，单镊片7被按压后会因为弹力而弹起。本发明超声镊结构合理，同时具有组织切除和凝固止血功能，使用安全方便，手术效果好。对于切割甲状腺等精细的开放式手术，可使用一种手术刀具代替超声剪、双极电凝镊这两种刀具的功能。The spring sheet 8 can ensure that the single tweezers sheet 7 and the cutter bar 1 form a certain angle in a natural state, which is almost the same as the common single tweezers sheet in appearance, and the single tweezers sheet 7 will spring up due to elastic force after being pressed. The ultrasonic tweezers of the present invention have a reasonable structure, simultaneously have the functions of tissue excision and coagulation and hemostasis, are safe and convenient to use, and have good operation effects. For delicate open operations such as cutting the thyroid gland, a single surgical knife can be used to replace the functions of the ultrasonic scissors and the bipolar coagulation forceps.
