The specific embodiment
In order more at large to understand technical scheme of the present invention, the present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, use of the present invention
InThe aimed positioning system for the treatment of fracture of pelvis comprises two two the identical cap neds 1 in left and right, two identical localizers 2, a connecting rod 3, two identical locking pins 5 and two set bolts 6.Cap ned 1, localizer 2, connecting rod 3 and set bolt 6 are by the titanium alloy manufacturing, and locking pin 5 is by steel making.
As Fig. 2, described cap ned 1 comprises square tube 1.1, supporting pipe 1.2 and 1.3 3 parts of aiming pipe, and square tube 1.1 is identical with the pipe range that aims at pipe 1.3, and supporting pipe 1.2 is fixedly connected on square tube 1.1 and aims at the middle part of pipe 1.3.Square tube 1.1 is the tube-like piece of 1mm for cross section for square, wall thickness, and the outer edge lengths of its cross section is 8-11mm, is preferably 10mm.The external diameter of supporting pipe 1.2 is 8-11mm, and preferred external diameter is 10mm, and its length is 170-220mm, and preferred length is 200mm.Aiming at pipe 1.3 is the inner wall smooth pipe of 8-11mm for wall thickness 1mm, external diameter, and preferred external diameter is 10mm.The length of square tube 1.1 and aiming pipe 1.3 is 100-200mm, and for example, for satisfying the application of Fei Of-thin height different crowd, the length that has designed square tube 1.1 and aiming pipe 1.3 is the cap ned of 100mm, 150mm and three kinds of different models of 200mm.The inner side end of square tube 1.1 is provided with a circular hole, can pass this circular hole, so that set bolt 6 can fixed connecting rod 3 when the described aimed positioning system of assembling.Described circular hole is arranged on apart from about 30mm place, square tube 1.1 medial extremity ends.In assembling during aimed positioning system of the present invention, the square tube 1.1 that needs to guarantee two cap neds 1 has the circular hole end in opposite directions and right.
As Fig. 3, localizer 2 comprises two identical sleeve pipes 2.1 and 2.2, the length of these two sleeve pipes is a bit larger tham the length that aims at pipe 1.3, and external diameter is slightly smaller than the internal diameter that aims at pipe 1.3, closely cooperates to guarantee that the first sleeve pipe 2.1 can insert to aim in pipe 1.3 and form.Hinged pattern connects together an end described two sleeve pipes (the first sleeve pipe 2.1 and the second sleeve pipe 2.2) with universal joint, and arc inserting handle 2.3 is arranged on the place near two sleeve pipe other ends.The first sleeve pipe 2.1 is sleeved on to aim in pipe 1.3 and form and closely cooperates, in addition, aim at pipe 1.3 and have breach at the hinged end of the second sleeve pipe 2.2, thereby regulate angle between the first sleeve pipe 2.1 and the second sleeve pipe 2.2 to guarantee that the second sleeve pipe 2.2 can rotate to an angle at hinged end, and be fixed the location by arc inserting handle 2.3.Arc inserting handle 2.3 can pass aiming pipe 1.3 and fixedly fix on (as Fig. 3) on the first sleeve pipe, also can directly be fixed on and aim on pipe 1.3 (as Fig. 1).
Lian Jie Defend 3 is foursquare solid titanium bar for the cross section as shown in Figure 4, the one side is marked with the scale take millimeter as unit, its length is 200-400mm, generally can design according to the length of square tube 1.1, generally can be 400mm, the foursquare length of side in its cross section is as the criterion can insert square tube 1.1 and to form to closely cooperate, for example, when outside the cross section of square tube 1.1, the length of side was 10mm, the length of side in connecting rod cross section can be slightly smaller than 8mm.
Fig. 5 shows the shape of locking pin 5, and the external diameter of described locking pin is 2mm, is about 300mm.Described locking pin 5 also can be made as oblateness.
Describing the present invention below in conjunction with operation process uses
InThe occupation mode of the aimed positioning system for the treatment of fracture of pelvis.
Before operation, at first with locking pin 5 oblique be positioned the periosteum surface enter the pin mark place, then with another root locking pin 5 oblique be positioned offside periosteum surface go out the pin mark place; Then respectively the second sleeve pipe 2.2 of two localizers 2 is inserted in along two locking pin 5 tail ends from hinged end, until the second sleeve pipe 2.2 hinged ends of two localizers 2 arrive respectively into the pin mark place and go out the periosteum surface at pin mark place, at this moment, the medial extremity of the aiming pipe 1.3 of two cap neds 1 in left and right (being also the round-meshed end of tool) should be respectively entering pin mark and going out pin mark place (as Fig. 1) on the periosteum surface.Then, connecting rod 3 is inserted in the square tube 1.1 of two cap neds 1, and according to entering pin mark and go out distance in the square tube 1.1 that distance adjustment connecting rod 3 between pin mark enters two cap neds 1, the bolt 6 that is tightened is fixed in square tube 1.1 connecting rod 3.At last, adjust and fix arc inserting handle 2.3 between the first sleeve pipe 2.1 and the second sleeve pipe 2.2, make the axis of the first sleeve pipe 2.1 and the second sleeve pipe 2.2 be basically perpendicular to the periosteum surface.Two cap neds 1 and connecting rod 3 are common forms rectangular configuration, and the long limit of rectangle can regulate the length of the connecting rod 3 that is exposed to cap ned 1 outside at any time in art, facilitates operation technique, the use after Fig. 1 shows and assembles
InThe aimed positioning system for the treatment of fracture of pelvis.
During operation, the principle that is parallel to each other according to the corresponding both sides of rectangle, only need to be from entering pin mark one side along being inserted in the direction that aims at the first sleeve pipe 2.1 in pipe 1.3, pierce guide needle (guide needle and positioning needle are basic identical) and make it to pass fracture line with electric drill and stretch out the pin mark place, this guide needle can be passed through out pin mark and be stretched into smoothly the first interior sleeve pipe 2.1 of offside aiming pipe 1.3, aims at and completes.Utilize system of the present invention, substantially can reach the purpose of disposable aiming.After aiming is completed, guide needle is passed fracture line and is retained in bone, at this moment, detachable and take off the aimed positioning system for the treatment of fracture of pelvis of the present invention, then after using the hollow boring bit reaming along guide needle, be screwed into again the operation half-thread lag screw commonly used that is complementary with the guide needle diameter, can complete the operation purpose that fracture of pelvis aims at and fixes under Wicresoft's condition.
