Description

Technical Field

[0001] The present invention relates to the technical field of surgical retractors, and in particular to a surgical retractor based on multi-directional synchronous action. Background Art

[0002] A surgical retractor is a medical device widely used in surgical operations. Its main function is to retract the tissues around the surgical incision to expose the surgical field and facilitate the doctor's operation. A retractor, also known as a retractor, is used to retract tissues to reveal the surgical scope for exploration and operation. It can be divided into two categories: hand-held retractors and automatic retractors. There are various shapes and sizes, and the appropriate retractor can be selected according to the needs of the operation.

[0003] Usually, the surgical retractors required for small incision surgery are all hand-held, but the opening angle of the hand-held surgical retractor is limited by its own size, and there is no guarantee that the surgical retractor can be fully adapted when selecting the surgical retractor. If the selected surgical retractor can provide a wound large enough for surgery when opened to the maximum, it can be used normally. However, if the selected surgical retractor cannot expand the wound to the required size when opened to the maximum, it will affect the normal progress of the operation. At this time, temporary replacement of the surgical retractor will cause secondary damage to the patient's wound and increase the difficulty of the operation. Summary of the invention

[0004] The purpose of the present invention is to provide a surgical retractor based on multi-directional synchronous action, wherein the first tooth plate is pulled by a pull ring, the first tooth plate drives the first gear to rotate, the rotation of the first gear drives the second gear to rotate, the second gear drives the second tooth plate to move, the movement of the second tooth plate drives the support rod to move, and the movement of the support rod allows the surgical retractor to be opened at a larger angle to solve the problem that the surgical retractor cannot open the wound to the required size even when it is opened to the maximum.

[0005] To achieve the above-mentioned purpose, a surgical retractor based on multi-directional synchronous action is provided, comprising a control panel, and two groups of control panels are arranged opposite to each other, the adjacent sides of the two groups of control panels are fixedly connected with vertical rods, the adjacent sides of the two groups of vertical rods are rotatably connected through movable parts, the bottom of the vertical rod is fixedly connected with a handle, and the top of the control panel is provided with a support rod;

[0010] As a further improvement of the present technical solution, a top groove is provided at the top of the limit frame, an L-shaped groove is provided at the top of the control board, and a support rod is fixedly connected to the top of the second tooth plate. The support rod passes through the top groove and the L-shaped groove in sequence and extends to the top of the control board.

[0011] As a further improvement of the technical solution, a support head is fixedly connected to the top of the support rod.

[0012] As a further improvement of the present technical solution, a fixing rod is fixedly connected to the bottom of the inner cavity of the control panel, a mounting plate is fixedly connected to the top of the fixing rod, a limiting rod is movably connected to the top of the fixing rod, the top of the limiting rod passes through the mounting plate, a pressure plate is fixedly connected to the surface of the limiting rod, cylinders are fixedly connected to both sides of the top of the mounting plate, the mounting plate is fixedly connected to the top with a spring, the inner side of the spring contacts the surface of the cylinder, and the top of the spring contacts the bottom of the pressure plate, the top of the limiting rod is fixedly connected to a docking tooth plate, a second slot is provided at the bottom of the limiting frame, and the docking tooth plate is meshed with the second tooth plate through the second slot.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the surgical retractor based on multi-directional synchronous action, the first tooth plate is pulled by the pull ring, the first tooth plate drives the first gear to rotate, the rotation of the first gear drives the second gear to rotate, the second gear drives the second tooth plate to move, the movement of the second tooth plate drives the strut to move, and the movement of the strut makes it possible to adjust the opening angle of the surgical retractor to a larger extent, thereby avoiding the situation where the surgical retractor cannot open the wound to the required size even when it is opened to the maximum, and the surgical retractor cannot be temporarily replaced, thereby reducing damage to the patient and making the operation go more smoothly.

[0016] 2. In the surgical retractor based on multi-directional synchronous action, when the pulling of the first tooth plate stops, the telescopic rod contracts. At this time, the pressure plate moves upward under the elastic force of the spring. The movement of the pressure plate drives the limit rod to move. The movement of the limit rod drives the docking tooth plate to engage with the second tooth plate, so that the second tooth plate is fixed and the support rod no longer moves, making the structure stable and having good resistance to cope with the squeezing of the patient's wound, thereby ensuring the normal progress of the operation.

[0029] See also Figure 1-Figure 7 As shown, the present embodiment aims to provide a surgical retractor based on multi-directional synchronous action, including a control panel 1, and two groups of control panels 1 are arranged opposite to each other, the adjacent sides of the two groups of control panels 1 are fixedly connected with vertical rods 2, the adjacent sides of the two groups of vertical rods 2 are rotatably connected through a movable member 4, the bottom of the vertical rod 2 is fixedly connected with a handle 3, and the top of the control panel 1 is provided with a support rod 16;

[0030] The control board 1 is provided with an inner cavity, and the inner cavity of the control board 1 is provided with a first tooth plate 10 and a second tooth plate 13. The first tooth plate 10 controls the second tooth plate 13 to move toward the outside of the control board 1 by moving downward, and the second tooth plate 13 moves outward to drive the support rod 16 to move. The two groups of support rods 16 move outward at the same time to expand the opening of the surgical retractor and expand the support range of the surgical retractor.

[0031] T-slots 9 are provided at the top and bottom of one side of the control board 1. The upper and lower ends of the first tooth plate 10 extend to the top and bottom of the control board 1 through the T-slots 9 respectively. A pull ring 11 is fixedly connected to one end of the first tooth plate 10 extending to the bottom of the control board 1.

[0032] The rack width of the first tooth plate 10 is smaller than the width of the plate. The T-slots 9 can clamp the plates on both sides of the first tooth plate 10 without affecting the movement of the rack, making the structure more stable.

[0033] The inner cavity of the control panel 1 is rotatably connected to a first rotating rod 5, and a first gear 6 is fixedly connected to the surface of the first rotating rod 5. One side of the first gear 6 meshes with one side of the first tooth plate 10. The inner cavity of the control panel 1 is rotatably connected to a second rotating rod 7 located on one side of the first rotating rod 5. A second gear 8 is fixedly connected to the surface of the second rotating rod 7. One side of the second gear 8 meshes with the other side of the first tooth plate 10.

[0034] The inner cavity of the control board 1 is fixedly connected to a limit frame 12 located above the second gear 8. The inner cavity of the limit frame 12 is provided with a second tooth plate 13. The bottom of the limit frame 12 is provided with a first slot 14. The top of the second gear 8 is meshed with the second tooth plate 13 through the first slot 14.

[0035] The limiting frame 12 provides support for the second tooth plate 13 so that it has a basis, and the second tooth plate 13 is slidable inside the limiting frame 12 and will not affect the normal movement of the second tooth plate 13 .

[0036] The first tooth plate 10 is pulled by the pull ring 11, and the first tooth plate 10 drives the first gear 6 to rotate, and the rotation of the first gear 6 drives the second gear 8 to rotate, and the second gear 8 drives the second tooth plate 13 to move, and the movement of the second tooth plate 13 drives the support rod 16 to move. The movement of the support rod 16 allows the opening angle of the surgical retractor to be adjusted to a larger extent, avoiding the situation where the surgical retractor cannot open the wound to the required size even when it is opened to the maximum, and the surgical retractor cannot be temporarily replaced, thereby reducing damage to the patient and making the operation go more smoothly.

[0037] A top groove 15 is formed at the top of the limit frame 12, an L-shaped groove 27 is formed at the top of the control board 1, a support rod 16 is fixedly connected to the top of the second tooth plate 13, the support rod 16 passes through the top groove 15 and the L-shaped groove 27 in sequence and extends to the top of the control board 1, and a support head 17 is fixedly connected to the top of the support rod 16.

[0038] The support head 17 is arc-shaped to avoid unnecessary damage to the patient's wound due to sharp edges. At the same time, multiple sets of baffles can be provided on the support head 17 to increase the contact area and prevent the support head 17 from sliding when supporting the wound, thereby improving the stability of the structure.

[0039] The shape of the top groove 15 is the same as that of the L-shaped groove 27, both of which are open at the top and one side. This design is because the support rod 16 not only needs to extend to the top of the limit frame 12 and the control board 1, but also needs to expand to both sides through gear cooperation. At this time, the support rod 16 must extend out of the limit frame 12 and one side of the control board 1. Therefore, the shape of the top groove 15 and the opening of the L-shaped groove 27 are to facilitate the movement of the support rod 16 without causing any obstruction to the support rod 16.

[0040] A fixing rod 18 is fixedly connected to the bottom of the inner cavity of the control panel 1, and a mounting plate 19 is fixedly connected to the top of the fixing rod 18. A limiting rod 20 is movably connected to the top of the fixing rod 18. The top of the limiting rod 20 passes through the mounting plate 19, and a pressure plate 23 is fixedly connected to the surface of the limiting rod 20. Cylinders 21 are fixedly connected to both sides of the top of the mounting plate 19. The top of the mounting plate 19 is fixedly connected to a spring 22, and the inner side of the spring 22 contacts the surface of the cylinder 21, and the top of the spring 22 contacts the bottom of the pressure plate 23. A docking tooth plate 24 is fixedly connected to the top of the limiting rod 20, and a second slot 25 is provided at the bottom of the limiting frame 12. The docking tooth plate 24 meshes with the second tooth plate 13 through the second slot 25. A telescopic rod 26 is fixedly connected to the top of the inner cavity of the control panel 1, and the telescopic end of the telescopic rod 26 contacts the top of the pressure plate 23.

[0041] When the first tooth plate 10 stops pulling, the telescopic rod 26 contracts. At this time, the pressure plate 23 moves upward under the elastic force of the spring 22. The movement of the pressure plate 23 drives the limit rod 20 to move. The movement of the limit rod 20 drives the docking tooth plate 24 to engage with the second tooth plate 13, so that the second tooth plate 13 is fixed, and the support rod 16 no longer moves, so that the structure is stable and has good resistance to cope with the squeezing of the patient's wound, ensuring the normal progress of the operation.

[0042] Working principle: first adjust the angles of the two sets of support rods 16 to a smaller value, and then make the support head 17 contact the two sides of the patient's wound. Then slowly close the two sets of handles 3 to make the angle of the support rod 16 gradually increase. When the angles of the two sets of handles 3 that fit the support rod 16 are opened to the maximum and still cannot meet the required size of the wound, pull the two sets of pull rings 11 with the index finger and the middle finger at the same time, and pull the first tooth plate 10 with the pull ring 11, the first tooth plate 10 drives the first gear 6 to rotate, the rotation of the first gear 6 drives the second gear 8 to rotate, and the second gear 8 drives the The second tooth plate 13 is moved, and the movement of the second tooth plate 13 drives the support rod 16 to move. The movement of the support rod 16 allows the surgical retractor to open at a larger angle, so that a wound suitable for surgery is obtained. Then the telescopic rod 26 is retracted, and at this time, the pressure plate 23 moves upward under the elastic force of the spring 22. The movement of the pressure plate 23 drives the limit rod 20 to move. The movement of the limit rod 20 drives the docking tooth plate 24 to engage with the second tooth plate 13, so that the second tooth plate 13 is fixed, and the support rod 16 no longer moves, and finally the surgery can be performed.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
