DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the utility model.

[0021] Reference Figure 1-Figure 3A retractor for orthopedic surgery convenient for observation comprises a horizontal plate 1, a fixing block 2 is fixed to one end of the horizontal plate 1 by bolts, a slider 4 is arranged on the outer side of the horizontal plate 1, a position avoidance opening 12 is provided in the slider 4, and the horizontal plate 1 passes through the position avoidance opening 12, so that the slider 4 moves along the horizontal plate 1, a retractor body 3 is welded on the same side of the fixing block 2 and the slider 4, a plurality of clamping holes 7 penetrating the horizontal plate 1 are provided on the upper surface of the horizontal plate 1, a plug hole is provided at the top and bottom of the position avoidance opening 12 aligned with the clamping hole 7, a plug pin 8 is inserted in the plug hole and the clamping hole 7, and a position avoidance opening 12 is provided in the slider 4 to move The movable driving assembly pulls the pin 8 to move, so that the pin 8 is disengaged from the clamping hole 7 and the plug hole, and then the driving assembly drives the slider 4 to move along the horizontal plate 1. The slider 4 will drive the hook body 3 connected to it to move, and because the hook body 3 on the fixed block 2 cannot move, the moving hook body 3 will pull the wound open. When the wound is stretched to a suitable size, the pin 8 is inserted into the plug hole and the clamping hole 7 to fix the slider 4, thereby fixing the hook body 3. The staff does not need to pull it all the time for use, which improves the convenience of using the surgical retractor.

[0022] In the utility model, the driving assembly includes a rotating rod 11, which is rotatably connected to the top of the avoidance opening 12, and the bottom key of the rotating rod 11 is connected to a gear 10. A first avoidance groove 5 is opened on one side of the horizontal plate 1, and a rack 6 is fixed in the first avoidance groove 5 by bolts, and the gear 10 is meshed with the rack 6. A block 9 is welded on the top of the rotating rod 11 through the slider 4. When the block 9 is rotated, the block 9 will drive the rotating rod 11 to rotate, and the rotating rod 11 will drive the gear 10 to rotate. During the rotation process, the gear 10 will mesh with the rack 6 to make the slider 4 move along the horizontal plate 1.

[0023] In order to facilitate the staff to rotate the block 9, a second avoidance groove 15 is opened on one side of the block 9, and a telescopic rod 13 is fixed in the second avoidance groove 15 by bolts. One end of the telescopic rod 13 extends out of the second avoidance groove 15 and is fixed with a connecting block 14 by bolts. A cylinder 16 is fixed to the top of the connecting block 14 by bolts. The telescopic rod 13 is elongated, and then the block 9 is pulled to rotate by the connecting block 14 on the telescopic rod 13. A handle is fixed to the end of the horizontal plate 1 away from the fixed block 2 by bolts, and multiple grooves are opened on both sides of the handle.

[0024] Working principle: when it is needed, pull the latch 8 to move so that the latch 8 is disengaged from the card hole 7 and the plug hole, and then rotate the block 9, the block 9 will drive the rotating rod 11 to rotate, the rotating rod 11 will drive the gear 10 to rotate, and the gear 10 will mesh with the rack 6 during the rotation to make the slider 4 move along the cross plate 1, the slider 4 will drive the hook body 3 connected to it to move, and since the hook body 3 on the fixed block 2 cannot move, the moving hook body 3 will pull the wound open. When the wound is pulled to an appropriate size, insert the latch 8 into the plug hole and the card hole 7 to fix the slider 4, thereby fixing the hook body 3. The staff does not need to pull it all the time for use, which improves the convenience of using the surgical retractor.
