【技术实现步骤摘要】
一种外科用手术刀
本技术涉及一种外科用手术刀,属于外科医疗器械
技术介绍
手术刀是用于切开皮肤和肌肉的医疗刀具,刀尖用于修洁血管和神经,刀柄用于钝性分离;目前所使用的手术刀,结构简单,刀体无法根据使用者的掌型大小进行长度调节,严重影响手术操作。为解决上述问题,特提供一种新的技术方案。
技术实现思路
本技术的目的在于提供一种外科用手术刀,以解决上述
技术介绍
中提出的问题。为实现上述目的本技术采用以下技术方案:一种外科用手术刀,包括刀柄、刀头和刀片,所述刀柄上设置有柄套、传动槽与T型槽,所述柄套套设于刀柄前端,所述传动槽开设于刀柄内部,传动槽内部通过轴承过盈连接有传动螺杆,所述T型槽开设于刀柄底部,T型槽上穿设有支撑滑块,所述刀头上设置有滑块与插块,所述滑块一体成型连接于刀头后端,且滑块插设于传动槽内,滑块后端开设有传动螺孔,所述传动螺孔与传动螺杆螺纹连接,所述插块焊接于刀头前端侧面,插块外侧转轴连接有锁块,所述刀片后端开设有连接槽,所述连接槽套设于插块上。优选的,所述支撑滑块呈半圆形结构。优选的,所述插块分别与锁块、连接槽的尺寸相同。与现有技术相比,本技术的有益效果是:本技术柄套套设于刀柄前端,可有效防止刀柄意外滑落;T型槽开设于刀柄底部,且T型槽上穿设有支撑滑块,可轻松调节支撑滑块位置,提高了手部虎口与刀柄接触的舒适度;滑块插设于传动槽内,且滑块后端的传动螺孔与传动螺杆螺纹连接,可通过传动螺杆轻松带动刀头顺着传动槽前后直线运动;刀片后端开设有连接槽,且连接槽套设于插块上,可轻松将刀片安装于刀头上;插块外侧转轴连接有锁块,可轻松对刀片进行固定。附图说明图 ...
