Detailed description of the invention
Present invention also offers the method adopting skeleton hold-down screw high-precision positioner to be fixed screw location, comprise the following steps:
A, on human body, cut wound, with mosquito forceps blunt separation subcutaneous tissue and deep tissue, single hole guide pipe 7 is adopted to insert until skeleton from wound, position skeleton needing to install hold-down screw is correctly reached under the monitoring of x-ray ray machine, positioning needle, with intermediate throughholes, is inserted position skeleton needing to install hold-down screw by hold-down screw with electric drill;
If the initial implantation site inaccuracy of B positioning needle, then exit single hole guide pipe 7, retain initial alignment pin, and the rotational axis hole 4 of described guide pipe 1 is enclosed within initial alignment pin inserts human body, by rotating and swing the position of fine setting guide pipe 1, impel one of described first locating hole 51 and second locating hole 52 accurately can aim at fixed position, insert guide pin by the first locating hole 51 or the second locating hole 52;
C, finally exit initial positioning needle; interior expander 2 is enclosed within described guide pipe 1 and inserts human body; described trocar sheath 3 is enclosed within described interior expander 2; in adopting, expander 2 measures required screw length after guide pin reaming; exit guide pipe 1 and interior expander 2 again; hold-down screw with endoporus is socketed in guide pin, and in skeleton, is screwed into hold-down screw under trocar sheath 3 is protected.
With reference to Fig. 7, Fig. 8, shown in Fig. 9, the second embodiment of the present invention is substantially identical with the first embodiment, difference is only: described locating hole 5 is in and regulates in pipe fitting 8, the adjustment hole 9 arranged along its length is provided with in described guide pipe 1, the diameter of adjustment hole 9 is greater than adjustment pipe fitting 8, pipe fitting 8 is regulated to insert in adjustment hole 9, regulate in the middle part of pipe fitting 8 and be greater than with diameter the spheroid 81 regulating pipe fitting, in the middle part of described adjustment hole 9, corresponding described spheroid 81 is provided with left clip 91 and the right clip 92 in band dome shape parcel face, left clip 91 and right clip 92 are fixed on the sidewall of adjustment hole 9, parcel face and the spheroid 81 of described left clip 91 and right clip 92 form spherical pair structure, the cooperation place close-fitting of described parcel face and spheroid 81 has damping, damping can realize by arranging the thin layer increasing frictional force in both cooperation places, or also can rely on merely both close-fittings act on increase frictional force while do not hinder both relative movements when being subject to relatively large power.Doctor can be enclosed within after on initial alignment pin at the rotational axis hole 4 of guide pipe, fine rotation or swing guide pipe 1, locating hole 5 all cannot be made to aim at predetermined fixed position if rotate or swing guide pipe 1, then can realize regulating pipe fitting 8 medial extremity to adjust more flexibly by the mobile outer end of pipe fitting 8 that regulates, finally realize the exactitude position of the locating hole 5 of guide pipe 1.In the present embodiment, in order to manufacture spherical pair structure in adjustment hole 9, welding procedure can be adopted, pipe fitting 8 is regulated to adopt the structure of two lobe splits, left clip 91 and right clip 92 are first manufactured, then be welded to two lobes to regulate on the inwall of the adjustment hole 9 of pipe fitting 8 body, finally adjustment pipe fitting 8 welded.
