The cross bar 1, it is described referring to bar 2 and the second bar 41 be telescopic rod and the cross bar 1 and described referring to bar 2
In parallel.
Since the first bar 40 and the second bar 41 are hinged, so that the second bar 41 can be rotated along the first bar 40, in this way in determination
Behind the good position referring to bar 2, i.e. the direction to be passed through of pelvis puncture needle 6 determines, but its starting point does not determine also, can fix at this time
The second bar 41 firmly is rotated referring to bar 2, position of the guide pin casing 3 in the transverse direction on the outside of anterior superior spine body surface can be adjusted
It sets, and since second bar 41 is retractable structure, enables guide pin casing 3 vertical on the outside of anterior superior spine body surface
It is adjusted up position, in this way, can be by the adjusting in the two directions so that guide pin casing 3 is located just above anterior superior spine about
The center of 1cm and entrance of threading a needle in this, as pelvis puncture needle 6, penetrate, pelvis puncture needle 6 will not be sent out along guide pin casing 3
It is raw to distort, accurate positioning.
When specific adjusting, unscrews nut 43 and second bar 41 is rotated along hinge joint, wait turn to suitable position
When, nut 43 is tightened, so that nut 43 is fixed with position of the screw 42 to the second bar 41.
The retractable structure of the retractable structure of the cross bar 1 and second bar 41 are as follows: including interior bar 10 and outer bar 11,
Sliding slot is set in the outer bar 11, and one end of slide bar 12 is connect with the interior bar 10, described in the other end stretching of the slide bar 12
Sliding slot is outer and the end connects sliding lock 13, and the fixation of 11 relative position of the interior bar 10 and outer bar is carried out by sliding lock 13.
Without fastening, he only needs the and then variation of 1 length of cross bar and changes i.e. the retractable structure referring to bar 2
Can, as long as the length of cross bar 1 determines, the length referring to bar 2 also determines immediately.
Scalable cross bar 1 is in order to enable the auxiliary device can be suitably used for the human body of different building shape and in guide pin casing 3
In position fixing process by adjust cross bar 1 length enable have good positioning after guide pin casing 3 contacted with body surface, conveniently wear
Needle can be locked by sliding lock 13 after the figure according to human body regulates length, prevent it from changing and shadow in use
Ring locating effect.
Embodiment 2
The present embodiment the difference from embodiment 1 is that, it is described referring to bar 2 include telescopic shaft 20 and Kirschner wire 21, described gram
One end of family name's needle 21 is mounted on telescopic shaft 20, and the other end of the Kirschner wire 21 is connect with the end of the right vertical bar 5, due to
Cross bar 1 be it is telescopic, when the length of cross bar 1 changes, need referring to bar 2 also and then change, pass through design telescopic shaft
20 change with the variation of 1 length of cross bar, and telescopic shaft 20 can first be shunk when installing Kirschner wire 21, will gram
One end insertion of family name's needle 21 is fastened in telescopic shaft 20, and the other end is perpendicularly oriented to the right vertical bar 5, then elongates telescopic shaft again
20, may make Kirschner wire 21, vertical bar 5 is mobile until connect with right vertical bar 5, specific address to the right, be arranged on the right vertical bar 5 and
The identical hole of 21 diameter of Kirschner wire, Kirschner wire 21 are inserted into the Kong Bingneng fastening of right vertical bar 5, so that the installation pole of Kirschner wire 21
For convenience.
Specific application method are as follows: the auxiliary device of the application is placed in hip and closes position near bone by the position for determining patient
Outside the body surface set, adjustment position makes Kirschner wire 21 be parallel to the direction that pelvis puncture needle 6 will pass through, fixed vertical bar and kirschner
Needle is constant with the direction for guaranteeing Kirschner wire, then by the second bar of rotation 41 and flexible second bar 41, so that guide pin casing 3 is located at ilium
Center above Ant sup at about 1cm, then pelvis puncture needle 6 is inserted into from guide pin casing 3, such 6 side of extension of pelvis puncture needle
To being determining, accurate positioning.
The specific method of fixed vertical bar and Kirschner wire, which can be, is fixed device winding and the waist of patient with adhesive tape.
In the utility model, the terms such as the "upper", "lower", "left", "right" are subject to orientation shown in attached drawing, in attached drawing
Dotted line indicate the part that is blocked.
Above-described specific embodiment, to the purpose of this utility model, technical scheme and beneficial effects carried out into
One step is described in detail, it should be understood that being not used to limit the foregoing is merely specific embodiment of the present utility model
Determine the protection scope of the utility model, within the spirit and principle of the utility model, any modification for being made equally is replaced
