Abstract
The utility model relates to the field of medical appliance, in particular to a rib shear. The rib shear adopts the scheme as follows: a rib enclasping rod is arranged on the outward side surface of the shear blade; and a pulling spring is arranged between the rib enclasping rod and a fixed pin. When the rib shear is used for snipping ribs, the rib enclasping rod can enclasp the ribs so as to prevent a shear blade from sliding on the rib, thus reducing the snipping difficulty of the rib, and improving the working efficiency of medical personnel.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially is a kind of novel rib nippers.
Background technology
Cut at medical epipleural bone and to be used to cut off rib, the rib nippers that uses is generally the straight shape of the mouth as one speaks or moon type at present, and when operating, rib nippers slides easily, can not easily rib be cut off, and has brought difficulty to working doctor, has brought misery to the patient.
The utility model content
For overcoming above-mentioned technical problem, this utility model provides rib nippers a kind of rational in infrastructure, practical and convenient.
For realizing above-mentioned technical purpose, this utility model is realized by the following technical solutions: a kind of rib nippers, by two snips, two cut handle, a rotating shaft constitutes, it is characterized in that: be fixed with rib by pivot pin respectively on the outside side of two snips and hold bar tightly, the snip lateral surface is provided with a steady pin in addition, rib is held tightly between bar and the steady pin and is provided with extension spring, make rib hold bar generation elastic force inwards tightly, the snip lateral surface is provided with spacer pin in addition, limits rib and holds the position of bar free end on snip tightly.
This utility model is compared with conventional art, has following beneficial effect: when rib was cut off, rib is held bar tightly can will hold rib tightly, avoids snip to slide on rib, thereby has reduced the difficulty that rib is cut off, and has improved medical worker's work efficiency.
