Figures 3a to 3n show a sequence of views illustrating the procedure of establishing a strong mechanical connection between arm contact portion 341 330 positioning and coupling device 321. The Figures 3a, 3c, 3e, 3g, 3i, 3k and 3m show an overview of the relative orientation between the contact portion 341 and the coupling device 321. Figures 3b, 3d, 3f, 3h, 3j, 3l and 3n each show a corresponding enlarged view.

As can be seen in Figures 3a and 3b, an operator (not shown) moves the contact portion 341 towards the 321 device adapter in a proper orientation, so that the first notch 345a and the second notch 345b are engaged in the first projection 325a and the second projection 325b, respectively. The two projections 325a and 325b protrude from body 326 of the 321 device adapter.

The positioning arm 330 is provided with a pressurized mechanism 350, which can rotate with respect to a hinge 352 with small angular limits. The pressure mechanism 350 is provided with a spring 353, so that the pressure mechanism 350 it is maintained in the initial angular position shown in the figure 3rd.

The pressure mechanism 350 comprises an element 351 hook type, which is integrally formed with the mechanism 350 under pressure. The function of the pressurized mechanism 350 will be described. later.

The positioning arm 330 is provided In addition to a 360 locking device. According to the realization here described, the locking device is a rod 360, which is mechanically coupled to lever 295 shown in Figure 2d. As you can easily see, the locking rod 360 is able to fit with the mechanism 350 under pressure when the rod 360 lock moves down so that it comes in contact with mechanism 350 under pressure. The locking rod 360 is mechanically coupled to lever 295 so that, when the lever 295 moves clockwise, the 360 locking rod moves down. When lever 2 95 moves counterclockwise, the rod 360 lock moves up. A subject matter expert you will find several suitable solutions to carry out the mechanical coupling between lever 295 and rod 360 of blocking.

The adapter device 321 is provided with 327 immobilization element that has the shape of an edge. How it can be easily seen in figure 3a, the mechanism 350 a pressure is adapted to engage in element 327 of immobilization when contact portion 341 and element 321 adapter butt each other.

To establish a detachable connection between the contact portion 341 and the adapter element 321, the arm Positioning 330 moves manually towards element 321 adapter. This is represented in figures 3c and 3d.

As can be seen in Figures 3e and 3f, the contact portion 341 moves additionally towards the adapter element 321 so that the two notches 345a and 345b are they engage in the two projections 325a and 325b, respectively.

As can be seen in figures 3g and 3h, the positioning arm rotates with respect to the hinge around an axis that is defined by the two regions in which the two fixing elements 325a and 325b and the two elements 345a and 345b coupling do butt each other, respectively. Thus, the pressure mechanism 350 and the immobilization element 327 are they approach each other. When the 351 hook type element of the pressurized mechanism 350 stops against an upper side of the immobilization element 327, the pressure mechanism 350 will be shifted to the side.

Figures 3i and 3j show portion 341 of contact and adapter element 321 when they butt each other. However, the pressurized mechanism 350 has not yet moved from back to its normal position.

Figures 3k and 3l show portion 341 of contact and adapter element 321, which are fixed together by middle of the mechanism 350 under pressure. Due to an elastic force produced by the spring 353, the pressure mechanism 350 has been moved back to its normal position. Therefore, portion 341 of contact and the adapter element 321 are held together by middle of a three point bearing. The three point bearing includes the connection between the pressure mechanism 350 and the element 327 of immobilization and the two regions in which the two fixing elements and the two coupling elements stop each other, respectively. This way you can set a precise orientation between plate 210 and device 280 of guided (see figure 2a).

Figures 3m and 3n show a locked state of the mechanism 350 under pressure. The locked state is characterized due to the fact that an opening can be effectively avoided accidental and unwanted mechanism 350 under pressure. Thus, the locking rod 360 moves down so that the lower end of rod 360 engages in mechanism 350 to Pressure.

When the pressure mechanism 350 is in the locked state, the bone stabilization plate with respect to the adapter device 321, and the guiding device with respect to the positioning arm 330 represent a rigid medical system Therefore, a surgeon can grab the middle system by the handle 390 and place the plate of a broken bone of a patient. The device Guiding allows precise pre-drilling of holes within the bone tissue, in which the holes pre-drilled line up with holes Default bone stabilization plate. Thus, The guiding device works as a drilling template. After having pre-drilled, it introduce threaded screws into the bone tissue to stabilize the bone in its normal position.

After fixing the plate on the bone broken, the positioning arm that includes the device guided must be removed from the fixed plate to allow closing the trauma of the intervention. The closing usually ends Suturing the patient's skin.

To remove the positioning arm from the bone stabilization plate must be separated portion 341 of 321 element contact adapter. In this way, you first have to move the locking rod 360 up. Then it turn the positioning arm slightly counterclockwise clockwise, so that the pressure mechanism 350 is slide out of immobilization element 327. The disassembly of the contact portion 341 of the adapter element 321 can be complete by performing the procedure described above In reverse order.
