Background technology
Shaft fracture is one of the most common fracture clinically, especially Long bone fracture incidence rate is higher, maneuver or the mechanical traction closed reduction away from fracture site is adopted at usual shaft fracture, undesirable at shaft fracture closed reduction, when being particularly suspected to have soft tissue intercalation, can appropriate row Limited open reduction, after adopting reduction forceps instrument to carry out sclerite reset, hole on backbone with drilling director again, but two kinds of medical apparatus and instruments can not synchronously carry out, and increase the amount of bleeding of operating time and patient, doctor's complex operation.Adjustable shaft fracture reset boring steering tool can meet synchronously to carry out after shaft fracture resets pressurization drilling guide to, as publication number: 103476350A " operation sight device ", notification number: 203059909U " bone surgery three-dimensional localization sight ".Its pressurization of boring steering tool but the adjustable shaft fracture of above-mentioned prior art resets, fixing boring point are only one, so under the occasion fractureed completely at long diaphysis or can not meet the needs of operation.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of adjustable shaft fracture reset pressurization boring steering tool, can fix boring, and carry out manual pressure in diaphyseal bone broken line both sides.
Summary of the invention
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of adjustable shaft fracture reset boring steering tool, comprise the first drill bushing of the scalable adjustment of opposing arcs arc longitudinal direction and the angular adjustment seat along the removable adjustment of circular arc arc that circular arc arc, circular arc arc fill, its main points are: angular adjustment seat is provided with through hole, and the radiai adjustment sleeve pipe of removable adjustment is housed in through hole; The second drill bushing is equipped with in radiai adjustment sleeve pipe one end, and an expansion link stretches out from the radiai adjustment sleeve pipe other end, and radiai adjustment sleeve pipe can carry out telescopic adjustment relatively, and expansion link terminal is equipped with the 3rd drill bushing.
The first clamping screw the first drill bushing of the scalable adjustment of opposing arcs arc longitudinal direction being regulated rear location circular arc arc is equipped with as preferably; Angular adjustment seat is equipped with mobile the second clamping screw regulating rear location in circular arc arc, angular adjustment seat is also equipped with radiai adjustment sleeve pipe and moves the 3rd clamping screw regulating rear location; Radiai adjustment sleeve pipe is equipped with expansion link and carries out the 4th clamping screw that telescopic adjustment well locates afterwards.
As preferably, in the first drill bushing, be inserted with target guide pin, in the second drill bushing, be inserted with the first positioning needle, in the 3rd drill bushing, be inserted with the second positioning needle.
As preferably, circular arc arc is provided with angle index line, by preoperative scheme, can presetting angular adjustment seat i.e. the second drill bushing, the 3rd drill bushing angle.
This utility model beneficial effect compared with prior art: because it not only has the first drill bushing, the second drill bushing, and also have the 3rd drill bushing; Three-dimensional regulation can be made in the key position that first drill bushing, the second drill bushing, the 3rd drill bushing are fractured relatively, so it can adapt to the fixing boring in diaphyseal bone broken line both sides of different Skeletal sizes, and carries out manual pressure; Can reset to shaft fracture region and pressurize.Circular arc arc is provided with angle index line, by preoperative scheme, can presetting angular adjustment seat i.e. the second drill bushing, the 3rd drill bushing angle.In addition, it is rational in infrastructure, low cost of manufacture, uses convenient to operation in operation, is easy to promote.
