Abstract

The invention provides a multi-spiral groove root canal file. The multi-spiral groove root canal file comprises a handle, an elongated shank, a tapered file body and a closely connected file tip. At least two continuous spiral grooves are distributed along the tapered file body, and the grooves have the same spiral angle. The spiral grooves are distributed along the axial direction, and the distribution intervals are not uniform; by seeing from the first spiral groove to the file tip, the interval between the second spiral groove and the first spiral groove is relatively narrow; and by seeing from the second spiral groove to the file tip, the interval between the first spiral groove and the second spiral groove is relatively wide, and the edges of the spiral grooves are sharp cutting edges.

[0020] 图1〜12,对本发明的多螺旋槽根管锉进行了描绘,该根管锉为金属材料制成,采用不锈钢或者镍钛合金制造,在一个优选的实施例中,该根管锉由包括含有10〜40%的钛和20〜50%的镍的金属合金制成。 [0020] FIG 1~12, multi-spiral grooves endodontic file according to the present invention is depicted, the endodontic file made of metal material, stainless steel or a nickel titanium alloy, in a preferred embodiment, the tubes 10 ~ 40% metal alloy of titanium and nickel file containing 20~50% by comprising. 该根管锉设有一个柄部1,柄部I的横截面形状是圆形的,它的长度约为20〜40毫米。 The endodontic file has a handle portion 1, the cross-sectional shape of the shank portion I is circular, its length of about 20~40 mm. 柄部I的近端还设有一个用于手持的手柄4。 I proximal handle portion is also provided a handle for a handheld 4. 手柄4采用塑胶材料,经注塑与柄部I固定。 The handle 4 with plastic materials, I is fixed by injection molding with the shank. 与柄部I连接的是锉体2和锉尖3。 I is connected with the shank 2 and the file is the file tip 3. 锉体2是锥形的,其长度可以从2毫米至柄部I的全长,即约40毫米,在图1〜12所示的实施例中,锉体2的长度足以扩展到根管的全长,大约16_。 File body 2 is tapered, its length can be from 2 mm to the entire length of the shank portion I, i.e., about 40 mm in the embodiment shown in FIG 1~12, file length sufficient to extend into the body 2 of the root canal full-length, approximately 16_.

[0021] 锉体2的外周是锥形的,这样就形成了一个夹角C,大约在0.5〜4度。 [0021] The outer periphery 2 of the file body is tapered, thus forming an angle C, approximately 0.5~4 degrees. 在图1〜4所示实施例中,沿挫体2分布着两个连续的螺旋沟槽5、6。 In the embodiment shown in FIG. 1 ~ 4, distributed along the body 2 setback two consecutive spiral grooves 5,6. 如图3所示,沟槽5、6是一个弧形凹面,每一个弧形凹面都有一对切削刃5a和5b,6a和6b。 As shown, the arcuate grooves 5 and 6 is a concave surface 3, each of the arcuate concave surface has a pair of cutting edges 5a and 5b, 6a and 6b. 如图4所示,每一个弧形凹面以螺旋环绕锉体,形成螺旋沟槽5和6,沟槽5和6的边缘与锉体外圆相交形成锋利的刃□。 4, each arcuate concave surround file body in a helical, spiral 5 and 6 are formed, the groove 5 and the edge 6 with the file vitro circle formed by the intersection trench sharp edge □.

[0022] 螺旋沟槽5、6具有相同的螺旋角且沿轴向分布,但其分布间隔并不均匀,更具体地说,自第一道螺旋沟槽5向锉尖3方向看去,第二道螺旋沟槽6与第一到螺旋沟槽5,二者间距7相对狭窄:自第二道螺旋沟槽6向锉尖3方向看去,第一到螺旋沟槽5与第二道螺旋沟槽6的间距8相对宽广; [0022] The helical grooves 5, 6 have the same helix angle and the distribution in the axial direction, but spaced distribution is not uniform, more particularly, to a third direction as seen from the first file tip spiral track groove 5, two first helical grooves 6 and 5 to the helical groove, the two relatively narrow spacing 7: 6 from the second track spiral groove 3 seen in the direction of the file tip, the first and the second track spiral helical groove 5 6, the groove pitch is relatively wide 8;

[0023] 在图1〜4所示实施例中,螺旋沟槽5、6是连续的,二者螺旋间距7呈一条螺旋形锐边。 [0023] In the embodiment illustrated in FIG. 1 ~ 4, 5 and 6 are continuous helical groove, the helical pitch of the two helical 7 has a sharp edge. 此外,在图4中,螺旋间距8的轴向尺寸E约是沟槽的轴向宽度D的2〜4倍。 Further, in FIG. 4, 8 helical pitch axial dimension E is about 2 ~ 4 times the axial width D of the trench.

[0024] 在图5〜8所示实施例中,螺旋间距7具有一个相对较小的轴向尺寸,在图8中,螺旋间距8的轴向尺寸E约是螺旋间距7轴向尺寸D的2〜4倍。 [0024] In the embodiment illustrated in FIG. 5 ~ 8, the helical pitch 7 having a relatively small axial dimension, in FIG. 8, a helical pitch of about 8 axial dimension E is a helical pitch of 7 axial dimension D 2 ~ 4 times. 此外,螺旋间距7的轴向尺寸D约是沟槽的轴向宽度的I / 5〜I / 2。 Further, the axial dimension of the helical pitch D 7 about the axial width of the trench I / 5~I / 2.

[0025] 在图9〜12所示实施例中,设有三个连续的螺旋沟槽5、6、9,和一个相对较宽的螺旋间距8以及两个相对较窄的螺旋间距7。 [0025] In the embodiment shown in FIG. 9~12 embodiment, there are three continuous spiral grooves 6, 9, and a relatively wide pitch of the spiral 8 and two relatively narrow helical pitch 7. 在图12中,螺旋间距8的轴向尺寸E约是螺旋间距7轴向尺寸D的2〜4倍。 In Figure 12, the axial dimension of the helical pitch is about E 8 2 ~ 4 times the helical pitch of the axial dimension D 7.

[0026] 以上所示实施例中,根管锉螺旋槽沟的旋转方向是反旋的。 The illustrated embodiment [0026] above, the rotational direction of the root canal file helical grooves is de-rotated. 同样的,因手术医生的惯用手不同,本发明的多螺旋槽根管锉的螺旋槽沟的旋转方向也可以设为正旋的。 Also, because the surgeon's dominant hand different from the direction of rotation plurality of spiral grooves root canal file according to the present invention, a helical groove may be defined as a positive spin.
