Direction, the term of directionality are for illustrative purposes and not restrictive.
A kind of minimal invasion hollow nail according to the present invention is described in detail below in conjunction with Fig. 1-2 and is oriented to implant system.As
The attached drawing of example, the application is illustrated using shin bone 1 and fibula 2.As shown in Figs. 1-2, minimal invasion hollow nail of the invention
Being oriented to implant system includes reduction forceps 3 and diopter 4.After bone is reset, it is fixed by reduction forceps 3 to guarantee surgical procedure
In be able to maintain optimal reset state, then diopter 4 is fixed on reduction forceps 3, rotate diopter 4 to optimum position after, plant
Enter hollow nail.
Specifically, reduction forceps 3 include the first articulated jib and the second articulated jib.First articulated jib and the second articulated jib are hinged
It is connected with each other at point.First articulated jib, the second articulated jib are respectively divided into the first grip part 31 and the first clamping at hinge joint
Portion 32, the second grip part 33 and the second clamping part 34.First clamping part 32 and the second clamping part 34 are for clamping bone.It is excellent one
It selects in embodiment, the first clamping part 32 and the structure having the same of the second clamping part 34, it is highly preferred that the first clamping part 32 and
The longitudinal cross-section of two clamping parts 34 is substantially in semicircular arc.
First clamping part 32 and the second clamping part 34 are equipped with Rocker arm 47, and one end of Rocker arm 47 is by means of such as 7 spiral shell of Rocker arm 4
The fasteners such as nail 472 are hingeably fixed on the first clamping part 32 or the second clamping part 34, and the other end is equipped with along its thickness direction
7 through-hole 471 of Rocker arm 4 of extension.Rocker arm 47 directly can be hingeably fixed on the semicircular arc profile of clamping part, can also be by
Be arranged according to preferred embodiment shown in Fig. 1-2, that is, the first clamping part 32, the second clamping part 34 be additionally provided with it is outstanding from itself
Linking arm 48, Rocker arm 47 are rotatably secured on linking arm 48, can guarantee not set on the semi arch profile of clamping part with this
Set the structural strength that ensure that clamping part itself for the screw hole of connecting rocker arm 47 or through-hole etc..
Diopter 4 is arc mechanism comprising left unit 41 and right unit 42.Left unit 41 has left through hole 44 and a left side
Threaded hole 43, right unit 42 have right through hole 46 and right-hand thread hole 45, and the axis of left through hole 44 and right through hole 46
Axis is located at same straight line, and left-hand thread hole 43, right-hand thread hole 45 and 7 through-hole 471 of Rocker arm 4 cooperate.
In order to guarantee after reduction forceps 3 fix shin bone 1 and fibula 2, carry out fixed reset pincers 3 without both hands or machine etc.,
As shown in Figs. 1-2, in a preferred embodiment, the first grip part 31 is equipped with the screw rod 35 hinged with it, and the second grip part 33 is set
There is 3 through-hole of reduction forceps cooperated with screw rod 35.When reduction forceps 3 are tight by the bone being reset clamping, on adjusting screw rod 35
Nut 36 makes it tightly be against the second grip part 33.
In a preferred embodiment, oblong is set by the cross section of 7 through-hole 471 of Rocker arm 4.Whereby, it is taken aim at for fastening
4 fixing screws 473 of diopter of quasi- frame 4 can also move in the through-hole of oblong, guarantee that diopter 4 can also carry out with this
Fine tuning.
In a preferred embodiment, the axis of left-hand thread through-hole and/or right-hand thread through-hole is perpendicular to left through hole 44 and the right side
The straight line that the axis of through hole 46 is formed.
In a preferred embodiment, diopter 4 is by for U-board.
Operating process of the invention briefly described below:
1. operative doctor according to different fracture situations, first carries out the reduction of the fracture, fixed with reduction forceps 3 after the completion of resetting,
Screw the nut 36 on reduction forceps 3.
2. 4 fixing screws 473 of diopter successively penetrate 7 through-hole 471 of Rocker arm 4,43/ right-hand thread hole 45 of left-hand thread hole, inciting somebody to action
When diopter 4 goes to suitable position, 4 fixing screws 473 of diopter, 7 screw 472 of Rocker arm 4 are fastened respectively, diopter 4 is fixed
Above reduction forceps 3.Diopter 4 can rotate (two Rocker arm 4s 7 rotate in same direction at this time) along the direction arrow A or B in this process,
It integrally can also integrally be moved forward or rearward that (perpendicular to paper direction, two Rocker arm 4s 7 are at this time with phase along the direction arrow C or D
Opposite direction rotation).
3. adjusting diopter 4: doctor is that rotating fulcrum rotates diopter 4 with Rocker arm 47, after finding best implantation point, is screwed
7 screw 472 of Rocker arm 4.
4. starting to be implanted into hollow screw: cutting skin surface, be sequentially inserted into outer sleeve along left through hole 44, right through hole 46
5, (wherein the internal diameter of outer sleeve 5 is greater than the outer diameter of rotary head sleeve, and the internal diameter of rotary head sleeve is greater than for drill holder 6, guide pin sleeve 7
The outer diameter of guide pin sleeve 7).Guide pin is squeezed into (according to the guide pin for the bone selection of dimension suitable dimension fixed, to combine shin calf
It fractures this fracture, guide pin chooses the diameter of Φ 1.2-2.5mm, ruler needed for following spare part size is fractured with shin calf joint
It is very little) after, guide pin sleeve 7 is removed, is squeezed into hollow bone drill (Φ 2.5-4.8mm), drill holder 6 is removed, is implanted into hollow nail (Φ 3.5-
