DETAILED DESCRIPTION
[0016] The following is combined with Figure 1-3 The specific implementation modes of the present utility model are further described in detail.
[0017] The utility model comprises a pull rod 1, a connecting block 2 is fixedly connected to the front side of the pull rod 1, a first draw hook 3 is fixedly connected to the front side of the connecting block 2, and second draw hooks 4 which can be adjusted laterally are arranged on the left and right sides of the first draw hook 3, and the two second draw hooks 4 move synchronously relative to each other; a pull ring 5 is fixedly connected to the rear side of the pull rod 1, an anti-slip groove 6 is opened on the pull ring 5, and the pull ring 5 is inclined upward relative to the pull rod 1.
[0018] The device improves the hook head position of the retractor, and has two first retractors 3, which are fixedly connected to the pull rod 1, and two second retractors 4 are respectively located on the left and right sides of the second retractors 4, and the relative width between the two second retractors 4 can be adjusted, so that the hook head width of the device can be adjusted. This device can be used for skin incisions of different lengths, reducing the steps of switching retractor models during surgery and improving the efficiency of the surgery. The pull ring 5 is in a closed state, and the anti-slip groove 6 is located on the rear side of the pull ring 5. The pull ring 5 facilitates the pulling of the pull rod 1, and at the same time increases the friction between the hand and the pull rod 1 to prevent the pull rod 1 from separating from the user's hand during use.
[0019] The pull rod 1 is slidably connected to a slider 7 that can slide back and forth, and the bottom of the slider 7 is rotatably connected to two symmetrically distributed connecting rods 8. The other end of the connecting rod 8 is rotatably connected to a traction block 9. The front end of the traction block 9 is fixedly connected to the second hook 4, and the inner side of the traction block 9 is fixedly connected to a support rod 10 that is slidably connected to the connecting block 2.
[0020] The slider 7 is mounted on the pull rod 1 and can be adjusted forward and backward on the pull rod 1. The forward and backward movement of the pull rod 1 can drive the traction block 9 to move to the left and right sides through the connecting rod 8. The support rod 10 guides and supports the movement of the traction block 9, thereby ensuring that the traction block 9 can only move left and right relative to the connecting block 2, and at the same time ensuring that the movement of the second hook 4 relative to the first hook 3 is horizontal.
[0021] Pads 11 are fixedly connected to the left and right sides of the slider 7 , and screws 12 are threadedly connected to the upper side of the slider 7 .
[0022] The pads 11 are located on the left and right sides of the slider 7 to facilitate the user to push the slider 7. The screws 12 fix the position of the slider 7 to ensure that the slider 7 is fixed after the position is adjusted.
[0023] The handle is provided with a slide groove 13 cooperating with the screw 12, and scale lines 14 are provided on both sides of the slide groove 13; the connecting block 2 is provided with a cylindrical groove cooperating with the support rod, and a baffle 15 is fixedly connected to the end point of the support rod, and a spring 16 is provided between the two baffles 15.
[0024] The scale line 14 is provided with an indication on one side, and the scale line 14 and the indication are used to feedback the distance between the two second hooks 4, so as to facilitate the adjustment of the distance. The spring 16 has an outward elastic force on the two baffles 15 and the support rod, and the spring 16 assists in pushing when the traction block 9 moves to both sides.
[0025] The utility model has a novel structure, ingenious conception, and simple and convenient operation. Through the design, the utility model effectively solves the problem that the hook head of the existing orthopedic surgical retractor has a simple structure and cannot be adjusted laterally, resulting in the need to replace the retractor model during the operation, thereby affecting the operation time and causing waste of resources.
[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
