Specific embodiment
Referring to Fig. 1, a kind of round orifices orientation sight for fracture of femoral neck disclosed in this utility model, including：Body
Portion 1, clamping section 2, body 1 and clamping section 2 are for being rigidly connected (Fig. 1) or axle connects plus elastic connection (Fig. 2).
1st, body 1：
Body 1 is cylindric, it is also possible to according to the shape for making easy assurance of hand-type, it is also possible to do one in side
Handle.Body central region is provided with multiple insertion honeycomb circular holes 7.
According to the different situation of fracture site, the diameter of multiple insertion honeycomb circular holes has two kinds：
The diameter of all insertion honeycomb circular holes is identical, or, the diameter of 1,/10 1/2 insertion honeycomb circular hole is identical.
Multiple insertion honeycomb circular holes are disposed with following several embodiments：
Embodiment 1：
The centerline axis parallel of all insertion honeycomb circular holes, and the cross section perpendicular to body, pass through on the cross section of body
Logical honeycomb circular hole is uniformly distributed, or is distributed in geometry shape, such as circular, oval, or in circle plus cross etc., referring to Fig. 3,
Fig. 4.
The embodiment 1 is most commonly seen, as shown in Figure 1, it is assumed that this utility model is fixed using 4 bolts, four screws two
Two 1 groups, one group is on top, one group following, two groups of screws are each perpendicular to the section of body.
First, in the insertion honeycomb circular hole 7 of body 1, four holes perpendicular to the section of body are chosen, point
The drill bit that will not burrow puts in hole, burrows on the corresponding bone of hole.Then, by four bolt-inserting hole holes, tighten, then
Four are bolted on body 1, finally with nut 8 again, film making confirms, if it find that hole location or depth do not have
Predetermined scheme is reached, is readjusted.
Embodiment 2：
1/10 1/2 insertion honeycomb circular hole axially in parallel, the axis of insertion honeycomb circular hole on same plane M, its
Remaining insertion honeycomb circular hole axially in parallel, axis in another plane N, the two planes M and N in the angle β less than 15 °,
Intersect in the external Virtual intersection point 11 of body.
The embodiment 2 is special circumstances, as shown in Fig. 5, Fig. 6, it is assumed that using the parallel fixation of 2 bolts, in addition 2 spiral shells
Bolt is fixed with being in 10 ° or 15 ° of angle β with which.
First, this utility model of the body with four insertion honeycomb circular holes for meeting above-mentioned requirements is chosen.Then,
Carry out identical to burrow operation.
Embodiment 3：
The central axis of all of insertion honeycomb circular hole is not parallel, sees Fig. 7, in other words, any two insertion honeycomb circular hole
The plane that is located of central axis intersect each other with the plane at the central axis place of other any two insertion honeycomb circular holes
Or it is parallel.
The embodiment 3 be used for fracturing slight crack position near and for many places, fixing bolt can not adopt parallel mode, only
According to practical situation, preferable fixed effect is can be only achieved.
2nd, clamping section 2
Clamping section is elastic stainless steel plate symmetrical structure.
1) 2 one end of clamping section is rigidly connected or integrative-structure with body 1, and the other end is clipped in greater trochanter on the outside of neck of femur
Sclerotin on carry out stationary positioned.
Embodiment 4：Clamping section 2 is two panels elastic stainless steel plate, under normality, the distance between two panels elastic stainless steel plate etc.
In or be slightly less than the diameter of body 1, before burrowing on bone, two panels elastic stainless steel plate is opened by external force (using handss),
Be subsequently sandwiched in fracture bone or muscular tissue on after, as the elasticity of itself is remained stationary automatically, so as to clamp.This feelings
Condition, often because the elasticity decrease of corrosion resistant plate, can cause positioning to shift.
Embodiment 5：Clamping section 2 is two panels elastic stainless steel plate, and the end of corrosion resistant plate is respectively provided with screw 3.Under normality,
Diameter of the distance between the two panels elastic stainless steel plate slightly larger than body, before burrowing on bone, two panels elastic stainless steel plate
Be placed in the muscular tissue of fracture site, through fishbolt 5 in screw, nut 3 is tightened so as to clamping so that circular hole is fixed
Position sight is accurately positioned.Bolt 5 also can be connected with 2 guillotine type of clamping section, i.e. one end and clamping section
29 axle of upper arm connects, and the other end is spirally connected with the underarm 15 of clamping section 2.
2) 2 one end of clamping section and 1 elastic connection of body, the other end is clipped in the bone 4 of fracture or muscular tissue is enterprising
Row stationary positioned.
Embodiment 6：From unlike above-described embodiment 1,2, clamping section 2 is two panels corrosion resistant plate, including upper arm 9, underarm
15, corrosion resistant plate has pivot connector or shaft coupling 13, and there is 1 both sides of body pivot joint cave or axle to connect cave 12, in clamping section 2
Back-moving spring 14 is set between body 1 so that after external force is opened, be clamped by the elasticity of back-moving spring 14, body
Portion 1 is positioned, so as to ensure round orifices orientation sight can stationary positioned, so accurately can burrow.The embodiment upper
Arm 9, underarm 15 can increase the structure of the bolt 5 with embodiment 5.
The top of body also can increase leader in body side as handle.
This utility model is according to different needs, complete, the various models of series, all size.
It is divided to two kinds in big class：Body is identical, and clamping section is different.Body is different, and clamping section is identical.
Divide in group multiple：The main centerline axis parallel according to insertion honeycomb circular hole whether depending on.
In order to more clearly embody structure of the present utility model, it is explained below by practical operation embodiment 5：
1st, through x-ray fluoroscopy, pre-operative preparation, determines that fracture of femoral neck resets good, determining is carried out using this utility model
Location of operation and fixation, that is, select embodiment 1, embodiment 2, embodiment 3, embodiment 4, embodiment 5 or embodiment 6.
2nd, operation starts, first the aseptic list of sterilization paving, cuts skin and muscular tissue etc..
3rd, this utility model of the body with satisfactory insertion honeycomb circular hole is selected, its clamping section is clamped in
Predetermined position.Embodiment 2 is such as selected, then by the screw tightening of clamping section.
4th, predetermined insertion honeycomb circular hole is inserted with bolt to be had a competition, adjust operation plan.
5th, extract bolt out, drill bit is inserted predetermined insertion honeycomb circular hole and starts to burrow, to set depth.
