一种伸缩式手术刀柄的设计和使用方法

Design and application of a retractable scalpel handle

手术刀是临床外科领域常用工具,传统手术刀为刀片与刀柄分体式,存在刀片长度无法调节的局限,如使用不慎容易划伤医护人员。为解决上述问题,扬州大学附属医院(大连医科大学临床教学医院)普外科的医护人员设计了一种伸缩式手术刀柄,并获得了国家实用新型专利(专利号:ZL 201920203154.9)。伸缩式手术刀柄采用旋转伸缩套筒配合螺纹柱型刀柄的设计,以达到内置刀片的目的,通过旋转刀柄一端的转把,根据实际需要来调节手术刀片伸出套筒的长度。该装置结构简单易操作,能够通过调节刀片的长度达到精确手术操作的目的,同时可有效避免术中误伤医务人员。

The scalpel is the most practical tool for surgeons.The traditional scalpel is a blade with a split handle,but the length of the blade cannot be adjusted,and it is easy to scratch medical staff.In order to solve the above problems,a retractable scalpel handle was designed by the medical staffs of department of general surgery,Affiliated Hospital of Yangzhou University(Clinical Teaching Hospital of Dalian Medical University),and obtained the National Utility Model Patent of China(ZL 201920203154.9).The telescopic scalpel adopted the design of rotary telescopic sleeve and threaded column handle to achieve the purpose of built-in blade.By rotating the handle at one end of the handle,the length of the surgical blade extending out of the sleeve could be adjusted according to the actual needs.The structure of the device is simple and easy to operate.The adjustable blade length could also achieve the purpose of accurate operation while effectively avoiding the injury of medical personnel during the operation.
