Description

A kind of tissue sampling cutter
[technical field]
The utility model relates to a kind of fetching knife, specifically, refers to the fetching knife used when pathological tissue is drawn materials.
[background technology]
In surgical procedures, often need to carry out pathological tissue and draw materials.Although existing tissue sampling cutter form is different, ubiquitous problem is, for softer tissue, fixing of tissue specimen is often more difficult, and chipping qualities is not high.In addition on the one hand, existing tissue sampling cutter also exists in slicing processes, and thickness is difficult to regulate, the shortcoming larger to the crush injury of tissue block.
[utility model content]
The technical problems to be solved in the utility model is, for the defect that prior art exists, provides one to organize twolip fetching knife.
A kind of tissue sampling cutter, comprise handle of a knife, coupling arrangement and blade, handle of a knife is connected with blade by coupling arrangement, coupling arrangement comprises and connects main body, set screw and gib screw, also movable connection structure is comprised in described coupling arrangement, described movable connection structure is connected with blade one end, and described blade is twolip.
When using, the position of drawing materials required for being aimed at by tissue sampling cutter, pulls the thin slice of required tissue downwards, backward respectively between two cutting edge pieces, treats that movable blades is sagging.
In the utility model, described movable connection structure is inclined plane shape, and top is provided with at least one elastic device.
Incline device, can make blade planar stretch and activity downwards.In time moving back before elastic device, knife bar is straight, and elastic device can be made to fix, and when retreating, blade can naturally droop due to self gravitation, is convenient to take off group film-making.
In the utility model, described tissue sampling cutter also comprises blade space regulating device, and knife bar is connected with coupling arrangement by screw by described blade space regulating device.
By this regulating device, after being adjusted to suitable thickness, be fixed by screw, tissue sampling cutter just can cut the tissue of different-thickness.
The beneficial effects of the utility model are: structure is simple, once draws materials time saving and energy saving, and the tissue thickness of cutting is even, are convenient to regulate, simultaneously less to the crush injury of tissue block, respond well.
[accompanying drawing explanation]
Fig. 1 is the structural representation of tissue sampling cutter.
Wherein, 1, handle of a knife; 2, coupling arrangement; 3, blade; 4, set screw; 5, gib screw; 6, movable connection structure; 7, elastic device; 8, blade space regulating device.
[embodiment]
In order to make the technical solution of the utility model clearly understand, below in conjunction with accompanying drawing embodiment, the utility model is further described.
A kind of tissue sampling cutter, comprise handle of a knife 1, coupling arrangement 2 and blade 3, handle of a knife is connected with blade by coupling arrangement, coupling arrangement comprises and connects main body, set screw 4 and gib screw 5, also comprise movable connection structure 6 in described coupling arrangement, described movable connection structure 6 is connected with blade one end, and described blade is twolip, described movable connection structure is inclined plane shape, and top is provided with two elastic devices 7.Described tissue sampling cutter also comprises blade space regulating device 8, and knife bar is connected with coupling arrangement by screw by described blade space regulating device.
The utility model is described by embodiment, and those skilled in the art know, when not departing from spirit and scope of the present utility model, can carry out various change or equivalence replacement to these characteristic sum embodiments.In addition, under instruction of the present utility model, can modify to adapt to concrete situation and material to these characteristic sum embodiments and spirit and scope of the present utility model can not be departed from.Therefore, the utility model is not by the restriction of specific embodiment disclosed herein, and the embodiment in the right of all the application of falling into all belongs to protection domain of the present utility model.
