技术领域technical field
本发明涉及医疗手术器械技术领域，具体地涉及一种剪刀式超声外科手术器械。The invention relates to the technical field of medical surgical instruments, in particular to a scissor-type ultrasonic surgical instrument.
背景技术Background technique
超声外科手术器械是一种结合超声能量和高频能量的多功能使用的手术器械。电流集成手术器械的操作端通过设置可开合的钳口和可伸缩的刀片，使其具有夹持组织、高频电能凝结组织和使用刀片切断组织的多重功能。An ultrasonic surgical instrument is a versatile surgical instrument that combines ultrasonic energy and high frequency energy. The operating end of the current-integrated surgical instrument has multiple functions of clamping tissue, coagulating tissue with high-frequency electric energy, and cutting tissue with a blade by setting openable jaws and retractable blades.
在现有的超声外科手术器械中，剪刀式的超声外科手术器械因其剪刀式的夹持结构，更符合人手的操作习惯，因此也应用广泛。但是常规的剪刀式超声外科手术器械存在转动不便的障碍，尤其在人手单手操作时，由于人体腕部转动的局限，使得剪刀式的超声外科手术器械的转动角度和范围也十分有限，这对于复杂创口或一些需要调整姿势角度的操作动作带来非常大的阻碍。因此，如何解决剪刀式超声外科手术器械对于角度的调整来进行组织的剪切或凝闭是目前急需解决的问题。Among the existing ultrasonic surgical instruments, the scissor-type ultrasonic surgical instruments are more in line with the operating habits of human hands because of their scissor-like clamping structure, so they are also widely used. However, conventional scissor-type ultrasonic surgical instruments have the obstacle of inconvenient rotation, especially when operated with one hand, due to the limitation of human wrist rotation, the rotation angle and range of scissor-type ultrasonic surgical instruments are also very limited. Complicated wounds or some operations that require adjusting the posture angle bring great obstacles. Therefore, how to adjust the angle of the scissor-type ultrasonic surgical instrument to cut or coagulate tissue is an urgent problem to be solved at present.
