Embodiment Construction

[0009] Accompanying drawing shows the structure of medical scissors of the present invention, and rotating shaft 3 connects two halves of scissors body into a whole that can rotate relatively, and the rear end of two halves of scissors body is provided with handle 4 respectively, and the front end of scissors body forms concave Cutting edge 1 and convex cutting edge 2. The concave cutting edge 1 preferably uses the active edge whose blade surface angle is less than 30°, and the convex cutting edge 2 preferably adopts the passive edge whose blade surface angle is greater than 45° acute angle. The concave cutting edge 1 is further preferably a driving edge with an included angle of the edge surface less than 15°.

[0010] When the medical scissors of the present invention are made into tools for specially trimming nose hairs in the ENT department of a hospital, smaller specifications and models should be selected, especially the size of the front end, which should be able to be ...

Abstract

The invention discloses medical scissors. Two half parts of a scissor body is connected into a whole capable of making relative rotation through a rotating axle, handles are respectively arranged at the rear ends of the two half parts of the scissor body and an inner concave cutting edge and an outer convex cutting edge are formed at the front end of the scissor body. The invention is easier and securer to operate; and the probability of accidental injury is greatly reduced when the medical scissors are operated by the medical staff for curing the patients.

Description

technical field [0001] The invention relates to a medical device, in particular to scissors among tool devices, and is especially suitable for trimming nose hairs in the ENT department of a hospital. Background technique [0002] Scissors are a commonly used instrument in the medical field, and they have different uses and frequency of use in different departments of the hospital, but there is no substantial difference in the structure of the scissors, that is, the two halves of the scissors are connected by the shaft to form a relatively rotatable As a whole, the rear ends of the two halves of the scissors body are respectively provided with handles, and the front ends of the two halves of the scissors body respectively form cutting edges. The scissors with this structure have wide application range and strong interchangeability. However, the ends of the existing scissors blades generally form a sharp edge, which brings inconvenience to the use of the tool, and medical per...
