[0024] like Figure 1-13As shown, a medical surgical universal connecting rod comprises a universal connecting device, a connecting rod 6 and a fixing clamp 7. The front end of the fixing clamp 7 is fixedly connected to a connecting rod 6 extending forward. The front end of the connecting rod 6 is connected to another connecting rod 6 through a universal connecting device. The universal connecting device is composed of an L-shaped rod 1, a left clamping plate 2, a threaded rod 3, a screw handle 4, a right clamping plate 5, a toothed ring 8 and a retaining ring 10. The L-shaped rod 1 is a vertically bent cylinder. Both ends of the L-shaped rod 1 are provided with internal threads. Both ends of the L-shaped rod 1 are fixedly connected with toothed rings 8. One end of the L-shaped rod 1 faces leftward, and the other end faces upward. Clamps are provided at both ends of the L-shaped rod 1. The left clamping plate 2 is a rectangular block with a notch at the top. 9, its notch 9 runs through front and back, and an axial hole 11 begins to be formed at the bottom end of the notch 9, the axial hole 11 is directly the same as that of the connecting rod 6, and through holes 12 are opened on the end faces of both sides to pass through the notch 9, and a toothed pressure ring 8 is fixedly connected to the through hole 12 on one end face of the left clamping plate 2, the right clamping plate 5 is the same size and shape as the left clamping plate 2, the left clamping plate 2 and the toothed ring 8 at the left rod end of the L-shaped rod 1 are butt-jointed, and the right clamping plate 5 and the toothed ring 8 at the top rod of the L-shaped rod 1 are butt-jointed, and threaded rods 3 that are threaded into the threaded holes in the L-shaped rod 1 that are butt-jointed are inserted into the through holes 12 of the left and right clamping plates, and retaining rings 10 that press the clamping plates are fixedly connected at the ends of the threaded rods 3, and a rotary handle 4 is hinged at the rear of the retaining ring 10 of the threaded rod 3.

[0025] The left splint 2 is sleeved on the connecting rod 6 of the fixing clamp 7 through the axial hole 12, and the direction of the L-shaped rod 1 is adjusted by rotating the threaded rod 3 at the left splint 2 through the handle 4, so that the left splint 2 is clamped and fixed on its connecting rod 6; the right splint 2 is sleeved on the other connecting rod 6 through the axial hole 12, and the direction of the connecting rod 6 is adjusted by rotating the threaded rod 3 at the right splint 5 through the handle 4, so that the right splint 5 is clamped and fixed on its connecting rod 6. The end of the connecting rod 6 on the right splint 5 can be easily changed in direction and position under the adjustment of the two threaded rods 3 of the left and right splints, thereby meeting the requirements of surgical use.

[0026] like Figure 8 and Fig. 9 As shown, a coordinate point is drawn beside a point on the front end extension line of the connecting rod 6 of the fixing clamp 7 of the present invention and the prior art universal connecting rod, and the distance between the coordinate point and the connecting rod 6 of the fixing clamp 7 of the two devices is the same.

[0027] like Figure 10-13 As shown, in the present invention, if the end of the frontmost connecting rod 6 is to be adjusted to the coordinate point, it is only necessary to loosen the threaded rod 3 on the right clamping plate 5 by turning the handle 4 to loosen its axial hole, so that the right clamping plate 5 and the toothed pressure ring 8 of the L-shaped rod 1 are disengaged, and the right clamping plate 5 is allowed to swing with the vertical rod of the L-shaped rod 1 as the axis, and then the position of the connecting rod 6 is pulled up and swung to the coordinate point, and then the left clamping plate 2 is loosened to make the L-shaped rod 1 swing downward. The above operation can be completed by only loosening the two threaded rods 3.

[0028] With the prior art universal connecting rod, if the front end of the connecting rod 6 is to be adjusted to a coordinate point, since the connecting rods 6 fixed by the cross sleeve 13 through the top screw knob 14 are all cross-hinged, if it is to be adjusted to a specified position, a transverse connecting rod 6 must be added, and adjusting to the coordinate point will consume thinking time at one end, and adjusting the direction of a connecting rod 6 requires loosening a top screw knob 14, and adjusting the extension length of the connecting rod 6 requires loosening another top screw knob 14. The thinking time plus the adjustment time greatly reduces the work efficiency. During the operation, every second counts, and the prior art universal connecting rod is obviously not conducive to operation. The present invention can well solve the above problems and is very suitable for promotion.
