Description

Automatic tubular-bone extending and reduction fixing system
The present invention relates to a kind of surgical instruments, especially relate to a kind of multi-functional tubulose bone reduction fixed system that automatically prolongs.
Several years, the mankind continued to use the Therapeutic Method of artificial reduction synthetism to tubular bone fracture always, and the reduction para-position is low to the line precision.Divide internal fixation and external fixation with regard to its fixed form, then divide non-operation fixed splinting, the new material coating fixation in closed-plaster method and modern age, but said method can not guarantee stable again because of binding causes poor blood circulation after the reduction of synthetism position to prolong the traumatic part healing cycle.
Internal fixation (AO) Therapeutic Method after the operation of Chu Xianing in recent years, the fracture bonded area is big, and the fix tightly solidity is good, but that the operation level requires is high, and destroy blood circulation, infect easily again.Also will carry out second operation, so the patient suffering is big, financial burden is heavy.
The measure of treatment fracture in the world becomes the problem of many scholar's Recent study, and has multiple external fixator to come out.As: И JI И 3APOB, KROMER and FISHER external fixator all are manually or finely tune apparatus.And by " whole bone anchor " of our design though make artificial reduction always realize advantages such as apparatus reduction, also exist such as: spicule can not be adjusted, defectives such as single width spicule instability.
The objective of the invention is to: provide a kind of six direction that can realize three axles (X, Y, Z axle) of every section fracture smoothly that line is moved and around the machinery of the rotation para-position of two directions of an axle (axis of bone line Z axle), spicule can be adjusted, overcome the unsettled purpose of single width spicule, the far distance automatic operation of energy simultaneously avoids the medical worker to be subjected to roentgenization under X-ray.
The present invention is achieved in that this system is made up of reduction holder, motor operation assembly, remote controller (adopt cable power transmission ﹠ distribution formula button control type or microcomputer test oneself control type two kinds).
The reduction holder is three ring column support type structures, and left side ring has the worm gear of anglec of rotation groove, worm structure to finish rotation for rotatable employing.In, the compound gear of band external gear and outer worm-gear toothing is installed in the right ring, respectively with fit over ring on transmitting gear and worm screw be meshed, forms the screw thread width of cloth by transmitting gear and four pillars that adopt the external screw rod pattern, the right side is encircled and is moved freely thereon in making.Hand fastening type spicule clamping device is installed on the pillar, can fix the location spicule of any angle, three ring sides the additional spicule fixation clamp of the solid posture of screwed hole is arranged, in position fixedly epiphysis is reinforced spicule, at the left side ring and the right ring outside spicule adjustment rack of multi-directional ball structure is installed, transfer screw rod that multi-directional ball is moved up and down to transfer the spicule gradient to make the existing X-direction of folding bony process to line, the multi-directional ball place of spicule adjustment has strain-type force sensor to show synthetism pressure through display system, the hand fastening type shift unit is installed on the pillar is realized that by electric machine assembly (or manually) rotation displacement bar Y direction folding diostosis is to line.When the close joint of fracture site is within 5 centimeters,, can be added on four posts for guaranteeing that Y-axis to displacement, also has the cantilevered adapter.At left medium ring, be equipped with 11 groups of motor operation assemblies respectively and adopt straight cutting and two kinds of combination forms of flexible axle respectively at 11 places such as spicule frame shift unit.When electric motor starting, left rim gear wheel rotation makes bone reach line around the rotation of axis of bone line Z axle; Make medium ring, right ring finish the bone tension and compression and reach para-position along pillar (being axis of bone Z axle) move left and right; Multi-directional ball is moved finish the adjustment realization bone X axis at spicule inclination angle line; Shift unit superior displacement piece is moved finish folding bone Y-axis line.
Electric machine assembly adopts remote controller control.Remote controller can adopt two kinds of patterns, i.e. the regular grade button remote control control chamber formed of cable power allotter and by the senior button remote control control chamber that microsystem is formed, high and low grade of two class can doing to operate.After fixedly securing,,,, make the medical worker avoid contacting X ray carry out the reduction operation away from X source by observing the additional display image of X-ray machine for the accelerated bone healing can add installation magnetic block (will remove electric machine assembly) after fixing through reduction doubling bone.
Good effect of the present invention is:
1, can move by six orientation of wired, that the folding bone is finished in the wireless microcomputer operation X, Y, Z axle and rotate around the positive reverse of Z axle, the elongation that can omnibearingly finish the folding bone is to line, to bit motion.
2, operation can carried out away from the X ray district, so can make the medical worker avoid x-ray.
3, can be to the reduction of place fracture and fixing, also can be to the reduction of same bone double fracture and fixing, conveniently reach the dissect physiology degree that resets.
4, spicule is squeezed into direction and is not subjected to facility constraints, reduction automaticity height, and fixation, easy for installation, simple in structure, in light weight, be easy to carry.
5, can do synthetism and also can make bone under the dissect physiology reset case and prolong reaching, and can be with being intended to transfer long required size within one day.
6, synthetism is effective, does not perform the operation, and does not influence blood circulation, so wound healing is fast, and the fixing back of reduction patient can make appropriate exercise immediately.
