Abstract

The invention discloses an angle-adjustable clinical scalpel for an ophthalmology department, and relates to the technical field of medical instruments. The angle-adjustable clinical scalpel for the ophthalmology department comprises a scalpel rod, a positioning cylinder and a scalpel head, wherein an adjusting base is mounted on one side of the scalpel rod, a rotating rod is rotatably connected to the inner part of the adjusting base, and a fixing block is mounted in the position, in the middle of the surface of the rotating rod, of the adjusting base; fine adjustment structures are arranged at the two ends of the adjusting base, the positioning cylinder is mounted on the side, away from the scalpel rod, of the fixing block, a positioning structure is arranged in the positioning cylinder, the scalpel head is mounted in the middle of the side, away from the fixing block, of the positioning cylinder, and a pouring structure is arranged in the middle of the inner part of the scalpel head and the scalpel head. According to the angle-adjustable clinical scalpel for the ophthalmology department, through the arrangement of the rotating rod and an angle fine adjustment block, adjustment of the angle of the scalpel head is achieved, the requirements of different operations are met, meanwhile, the operations are more convenient and efficient, operation inconvenience caused by fixing of the angle of the scalpel head is avoided, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an angle-adjustable ophthalmic clinical scalpel. Background technique [0002] In today's increasingly developed world, more and more people suffer from eye diseases, so there are corresponding ophthalmology departments for treatment, and in the process of ophthalmology treatment, clinical operations are often required on patients, and the ophthalmic scalpel , is requisite a kind of surgical instrument in clinical operation, but existing ophthalmology clinical scalpel still has certain defective. [0003] After searching, the Chinese Patent Authorization Announcement No. CN208492471U, announced on February 15, 2019, discloses an ophthalmic scalpel with angle positioning function. The connected connecting part, the cutting part provided at the end of the connecting part and extending obliquely upwards, the cutting part is set at a certain angle with the connecting part,...
