For solving the problems of the technologies described above, present invention employs so a kind of clamp type pathologic sampling handle of a knife, it comprises two knife rests that can be connected; Described knife rest comprises blade clamping part, knife rest connecting portion, handle of a knife grip part; Described blade clamping part and described knife rest connecting portion affixed; Described handle of a knife grip part and described knife rest connecting portion affixed; The central axis of described blade clamping part and described handle of a knife grip part is positioned at the both sides of described knife rest connecting portion center of rotation axis; Two knife rests are hinged by described knife rest connecting portion; Described handle of a knife grip part end is provided with groove; Clamping component is hinged with in the handle of a knife grip part end groove of one of them knife rest.
In a kind of preferred embodiment of the present invention, described clamping component is the T-shaped threaded rod with nut.
In a kind of preferred embodiment of the present invention, described blade clamping part is also provided with limit component.
In a kind of preferred embodiment of the present invention, described limit component comprises the positive stop lug boss be arranged on the blade clamping part of a knife rest, and is arranged on the limited impression on the blade clamping part of another knife rest; Described positive stop lug boss is equal with described limited impression width.
In a kind of preferred embodiment of the present invention, the height of described positive stop lug boss projection is less than the degree of depth of described limited impression depression.
In a kind of preferred embodiment of the present invention, described knife rest connecting portion is discoid.
In a kind of preferred embodiment of the present invention, the knife rest connecting portion of one of them knife rest is provided with hinged projection; The knife rest connecting portion of another knife rest is provided with can with the hinge hole of described hinged male cooperation.
In a kind of preferred embodiment of the present invention, described handle of a knife grip part Surface coating has rubber or polyurethane.
The invention has the beneficial effects as follows: structure of the present invention is simple, by pathologic sampling handle of a knife being designed to two hinged knife rests in steel wire tong-like, easily and effectively achieving the clamping to blade and replacing; Simultaneously this pathological material-drawing knife handle can realize blade stability by the lever principle of clamp and clamps reliably, avoids dropping of blade in the process of drawing materials, the precision that ensure that the speed of drawing materials He draw materials; Last this case fetching knife handle is compatible strong, and can be suitable for the blade of the microtome of Multiple Type, easy to use, any Pathology Deparment, research institutions or hospital surgical, postmortem etc. can be suitable for.
