To achieve these goals, this utility model adopts following technical scheme:
The inner side formula biopsy forceps head that puts the first edge on a knife or a pair of scissors, comprises a pair of binding clip, and the cutting edge of two binding clips is all opened in the inner side of binding clip, when the jaw of two binding clips is closed, two jaws are identical in alignment, form shear surface, between the inclined-plane, outside of described cutting edge and shear surface, have angle; And the cutting edge of two described binding clips is measure-alike.
Wherein more preferably, described angle is the acute angle that is greater than 30 degree.
Wherein more preferably, described angle is between 45 °～60 °.
Wherein more preferably, the thickness at described cutting edge edge is between 0.02～0.05mm.
Wherein more preferably, the outer surface of described binding clip is circular arc, and the inner side of described binding clip is provided with jaw chamber, and the edge in described jaw chamber arranges cutting edge, and described jaw Qiang offers through hole in center.
Wherein more preferably, described binding clip is S-type, at the waist of binding clip, offers through hole, in one end of binding clip, cutting edge is set, and at the other end of binding clip, is provided for the end being connected with pull bar, and described end arranges through hole.
Or wherein more preferably, described binding clip is S-type, at the waist of binding clip, offer through hole, in one end of binding clip, cutting edge is set, at the other end of binding clip, be provided for the end being connected with pull bar, described end arranges boss.
Wherein more preferably, the center of described boss is provided with bellmouth.
A biopsy forceps, comprises the pair of inside formula biopsy forceps head that puts the first edge on a knife or a pair of scissors, and the cutting edge of two described binding clips is measure-alike.
Put the first edge on a knife or a pair of scissors formula biopsy forceps head and biopsy forceps thereof the disclosed inner side of this utility model.Be convenient on the one hand processing, compare with making the outside cutting edge of processing by hand binding clip in prior art, can use machining mode to process the cutting edge that inner side is offered, for example, can use machine glazed finish to realize the polish of cutting edge; On the other hand, the damage to cutting edge in the course of processing and handling process can be reduced, the scrappage of biopsy forceps can be effectively reduced.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, technology contents of the present utility model is described in detail.
Known in conjunction with Fig. 1 to Fig. 4, biopsy forceps provided by the utility model, comprises the pair of inside formula binding clip that puts the first edge on a knife or a pair of scissors.As shown in Figure 1, binding clip is S-type, the outer surface of binding clip is circular arc, and the inner side of binding clip is provided with jaw chamber, and jaw Qiang offers at center through hole 4(referring to Fig. 2), the marginal position in jaw chamber arranges cutting edge, the cutting edge of two binding clips is all opened in the inner side of binding clip, and the cutting edge of two binding clips is measure-alike, when the jaw of two binding clips is closed, two jaws are identical in alignment, form shear surface 10.
Referring to the orientation of Fig. 1, the binding clip of S type, the inner side cutting edge 3 arranging at the edge in the jaw chamber of the right-hand member of binding clip, offers through hole 2 at the waist of binding clip, at binding clip, away from one end of cutting edge 3, is provided for the end 1 being connected with pull bar.End 1 can be arranged to boss form as shown in Figure 1, also can offer through hole.Wherein, when through hole 2 is assembled for biopsy forceps, realize being located by connecting of binding clip and binding clip support, be arranged on the boss of end 1 or through hole for realizing the connection between binding clip and connecting rod, connecting rod is used for pulling binding clip folding.While boss being set on end 1, in order to facilitate the assembling of binding clip and pull bar, referring to the orientation of Fig. 2, can offer in the centre of boss upper surface bellmouth (not shown).
Known in conjunction with Fig. 3 and Fig. 4, cutting edge 3 is opened in the inner side of binding clip, and cutting edge 3 has smooth jaw inner cavity surface and the inclined-plane, outside 30 of inclination, has angle α shown in inclined-plane, outside 30 and Fig. 3 between horizontal shear face 10, angle α is greater than the acute angle of 30 °, preferably 45 °～60 ° uses.I portion enlarged drawing shown in Figure 4, in order to guarantee the shear effect of cutting edge 3, the thickness h at cutting edge 3 edges is arranged between 0.02～0.05mm.
In sum, the inner side provided by the invention formula binding clip that puts the first edge on a knife or a pair of scissors, by cutting edge being arranged on to the inner side of binding clip, cutting edge flat mouth intersects, and is more conducive to binding clip and captures pathological tissue, and inner cutter hole can improve the cutting edge interlock of biopsy forceps.
Meanwhile, biopsy forceps provided by the invention, because cutting edge is arranged on the inner side of binding clip; can effectively protect cutting edge, not be vulnerable to outside processing, the impact and injured of colliding with, no matter be manual grinding; or mechanical grinding, can not damage binding clip cutting edge even if process slightly deviation yet.A kind of a kind of probability of mechanical grinding polishing is so just provided, thereby effectively under the prerequisite of serviceability that guarantees biopsy forceps, has improved the working (machining) efficiency of binding clip sanding and polishing processing, and reduced scrappage.
Above put the first edge on a knife or a pair of scissors formula biopsy forceps head and biopsy forceps thereof of inner side provided by the utility model had been described in detail.For one of ordinary skill in the art, any apparent change of under the prerequisite that does not deviate from this utility model connotation, it being done, all will form this utility model infringement of patent right, will bear corresponding legal responsibility.
