Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of slicing knife of the present utility model;
Fig. 2 is the structural representation of the cutter core of slicing knife of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Embodiment 1
See Fig. 1, the present embodiment comprises can the shell 1 that regulates of bending and the cutter core 2 that is sheathed in described shell 1; Described shell 1 and the front end of cutter core 2 have corresponding via hole 11 and through hole 12, and described cutter core 2 external connection power device, rotates relative to shell 1 in shell 1; Described shell 1 is deformable bending adjustment, and accordingly, described cutter core 2 is soft body structure.As the concrete structure of shell 1, described shell 1 adopts the adjustment structure of deformable bending, bending and fixing to be shaped; The adjustment structure of the deformable bending of described shell 1 is: described shell 1 is formed by connecting by the multistage annulus that can mutually swing, and can carry out angular adjustment between every two-stage annulus, forms coil structure.When using the slicing knife of this structural housing 1 to perform the operation, doctor can at any time manually the shape of bending shell 1 pair of shell 1 regulate, thus realize carrying out position adjustments to the via hole 11 of the front end of shell 1, adapt to the size difference of the ear,nose & throat of different crowd, substantially increase the serviceability of slicing knife, facilitate the use operation of doctor, there is the feature of the efficiency improving operation.
As shown in Figure 2, the soft body structure of described cutter core 2 is: described cutter core 2 comprises the cutter hub 21, connecting axle 22 and the fixed bar 23 that connect successively, forms syllogic syndeton; Described cutter hub 21 is socketed on the front end of shell 1, and described through hole 12 is located on cutter hub 21.Described connecting axle 22 adopts wire cable, and described cutter hub 21 is rigid structure.When slicing knife works, power drives cutter hub 21 to carry out circumgyration incision by fixed bar 23 and connecting axle 22, both the flexibility having maintained cutter core 2 to adapt to the needs of the adjustment structure of the deformable bending of shell 1, in turn ensure that cutter hub 21 cut required for the hardness requirement that reaches.
Described cutter core 2 when rotated its through hole 12 is periodically connected with the via hole 11 of shell 1, is cut by the object entered in through hole 12.In order to the pathological tissues cut down by cutter hub 21 in time discharges shell 1, the wall of described shell 1 has the outlet for extracting object in through hole 12 out, described outlet is communicated with through hole 12, and for object is sucked through hole 12, and object through hole 12 internal cutting got off extraction is drained.
Described slicing knife is supporting working lens pipe, and during work, described slicing knife is sheathed in working lens pipe.Described working lens pipe is flexible structure, can flexural oscillations.Slicing is cut and is stretched into human body by working lens pipe and arrive pathological tissues.Under the restriction of working lens pipe, the cutter core of slicing knife stably can rotate and cut pathological tissues in shell 1.
The tail end of described fixed bar 23 is provided with push-pull structure, and it is by push-pull structure external connection power device; Described push-pull structure comprises Connection Block 3, and one end of described Connection Block 3 is fixedly connected on the end of fixed bar 23, the other end evenly has at least two slots 31; Described cutter core 2 is plugged on described power set by slot 31.Concrete, described power set are the device with rotary power output.
Embodiment 2
The present embodiment is on the basis of embodiment 1, and for the improvement of described shell, described shell 1 is flexible material, and the bending of shell 1 is deformed into elastic deformation.Such as, can adopt rubber, plastics or silica gel etc., other material with good toughness is also applicable to the manufacture use of shell certainly.
Above disclosedly be only this utility model preferred embodiment, certainly can not limit the interest field of this utility model with this, therefore according to the equivalent variations that this utility model claim is done, still belong to the scope that this utility model is contained.
