Description

Technical Field

[0001] The utility model relates to the technical field of fracture traction, in particular to a fracture surgery traction device. Background Art

[0002] Traction for lower limb fractures is a common method for treating lower limb fractures. It stretches the fracture site with external force to reduce it and keep it stable, thus promoting fracture healing. Traction for lower limb fractures mainly involves drilling holes at the fracture site or at the upper and lower ends of the fracture, passing steel needles or nails through the bones, and then traction with ropes and weights.

[0003] The existing traction bow needs to be pried apart at both ends of the traction bow during use, and the two ends of the traction bow need to be passed through the two ends of the steel needle, and then the steel needle and the traction bow need to be fixed together using bolts on the traction bow.

[0004] However, in actual use, when the two ends of the traction bow and the steel needle are connected, the traction bow itself has a certain strength and toughness, which may cause contact with the steel needle during the connection process, causing the steel needle to shake and causing secondary injury to the patient. Secondly, during the fixation process, the bolts on the steel needle and the traction bow are made of metal, which may cause slipping after fixation, resulting in unbalanced traction. Utility Model Content

[0005] The purpose of the utility model is to provide a traction device for fracture surgery to solve the problem that the steel needle comes into contact with the steel needle during the docking process, causing the steel needle to shake and causing secondary injury to the patient; secondly, during the fixation process, the steel needle and the bolts on the traction bow are both made of metal, which causes slipping after fixation, resulting in unbalanced traction.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a fracture surgery traction device, comprising two connecting blocks, the two connecting blocks are fixed at two ends of a traction bow, lower splints are respectively fixed on two sides of the two connecting blocks that are far away from each other, the lower splints are connected to an upper splint by a hinge, steel needles are arranged at both ends of the traction bow, the two ends of the steel needles are located between the lower splint and the upper splint, mounting openings are respectively provided on the bottom surface of the lower splint and the top surface of the upper splint, an arc-shaped rubber block is detachably provided inside the mounting opening, and slots are provided on both sides of the two arc-shaped rubber blocks that are close to each other.

[0007] Preferably, a sliding groove is provided on one side of the upper clamping plate close to the connecting block, a clamping rod is slidably arranged inside the sliding groove, a clamping groove is provided on the outer wall of the connecting block close to the upper clamping plate, the clamping groove corresponds to the position of the sliding groove, one end of the clamping rod passes through the sliding groove and is clamped inside the clamping groove, a spring is fixed to the other end of the clamping groove, and the other end of the spring is fixed to one side of the inner wall of the sliding groove.

[0008] Preferably, a limiting opening is provided on the top surface of the upper splint, the limiting opening is communicated with the sliding groove, a moving block is slidably arranged inside the limiting opening, the bottom surface of the moving block is fixed to the top surface of the clamping rod, and the top surface of the moving block is provided with anti-slip grooves.

[0009] Preferably, a plurality of mounting holes are respectively formed on the bottom surface of the lower clamping plate and the top surface of the upper clamping plate, and rubber mounting blocks are respectively fixed on two sides of the two arc-shaped rubber blocks away from each other, and the rubber mounting blocks are sleeved inside the mounting holes.

[0010] Preferably, a plurality of positioning grooves are respectively formed on both sides of the inner wall of the installation opening, and a plurality of positioning blocks are respectively fixed on the left and right sides of the arc-shaped rubber block, and the positioning blocks are plugged into the positioning grooves.

[0011] Preferably, protective covers are respectively provided at both ends of the steel needle, a rubber ring is fixed inside the protective cover, and a plurality of adapter ports are opened at equal angles on the inner wall of the rubber ring.

[0012] Compared with the prior art, the fracture surgery traction device using the above technical solution has the following beneficial effects:

[0013] 1. This fixation method can fix the traction bow and the steel needle without bending the two ends of the traction bow, ensuring that the steel needle will not shake during the fixation process and that the patient will not suffer secondary injuries. At the same time, this fixation method facilitates the operation of medical staff and improves the efficiency of fracture traction; the arc-shaped rubber block is fully in contact with the outer wall of the steel needle through the squeezing of the lower splint and the upper splint, and the anti-slip performance of the arc-shaped rubber block itself effectively improves the anti-slip performance of the traction bow and the steel needle after fixation, preventing slipping between the traction bow and the steel needle, ensuring that there is no compression during the traction process, and reducing the patient's pain. At the same time, when the traction bow needs to be removed after the operation, it can be more convenient without the need to significantly bend the traction bow, thereby reducing unnecessary risks;

[0014] Second, the protective cover can effectively protect the needle tips at both ends of the steel needle to prevent patients and medical staff from being stabbed, thereby protecting the safety of patients and medical staff. The rubber ring can be bent through the adapter to ensure that the contact area between the rubber ring and the surrounding wall of the steel needle is increased, preventing the protective cover from falling off. The arc-shaped rubber block can be replaced by removing the rubber mounting block from the inside of the mounting hole, so that different arc-shaped rubber blocks can be selected according to the thickness of the steel needle, ensuring that the notch on the arc-shaped rubber block matches the surrounding wall of the steel needle. By inserting the positioning block into the inside of the positioning groove, it can be effectively ensured that the arc-shaped rubber block will not be displaced, thereby improving the stability of the arc-shaped rubber block.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 4As shown, the fracture surgery traction device comprises two connecting blocks 1, the two connecting blocks 1 are fixed at two ends of a traction bow 2, lower splints 3 are fixed on two sides of the two connecting blocks 1 away from each other, an upper splint 4 is connected to the lower splint 3 by a hinge, steel needles 5 are arranged at two ends of the traction bow 2, the two ends of the steel needles 5 are located between the lower splint 3 and the upper splint 4, mounting openings 6 are respectively provided on the bottom surface of the lower splint 3 and the top surface of the upper splint 4, an arc-shaped rubber block 7 is detachably provided inside the mounting opening 6, notches are provided on two sides of the two arc-shaped rubber blocks 7 close to each other, and a sliding groove 8 is provided on one side of the upper splint 4 close to the connecting block 1. A clamping rod 9 is provided for sliding inside the sliding groove 8, and a clamping groove 10 is provided on the outer wall of the connecting block 1 close to the upper splint 4. The position of the clamping groove 10 corresponds to that of the sliding groove 8. One end of the clamping rod 9 passes through the sliding groove 8 and is clamped inside the clamping groove 10. A spring 11 is fixed to the other end of the clamping groove 10. The other end of the spring 11 is fixed to one side of the inner wall of the sliding groove 8. A limiting opening 12 is provided on the top surface of the upper splint 4. The limiting opening 12 is connected to the sliding groove 8. A moving block 13 is provided for sliding inside the limiting opening 12. The bottom surface of the moving block 13 is fixed to the top surface of the clamping rod 9, and the top surface of the moving block 13 is provided with anti-slip grooves.

[0023] In use, when the medical staff needs to fix the traction bow 2 and the steel needle 5 together, the medical staff flips the upper splint 4, which can be turned 180 degrees through the connection of the hinge, and the medical staff can place the steel needle 5 in the notch of the arc rubber block 7. At this time, the medical staff flips the upper splint 4 again, and the medical staff can pinch the two ends of the lower splint 3 and the upper splint 4 that are not closed. During the pressing process, one end of the clamping rod 9 will be blocked by the outer wall of the connecting block 1 and shrink toward the inside of the sliding groove 8. At this time, the spring 11 will be in a stressed state. After the lower splint 3 and the upper splint 4 are completely closed, the clamping groove 10 and the sliding groove 8 will be in a corresponding state, and at this time, the blocking force of the connecting block 1 disappears, and the clamping rod 9 will be plugged into the inside of the clamping groove 10 through the rebound force of the sliding groove 8. Through the plugging of the clamping rod 9 and the clamping groove 10, the lower splint 3 and the upper splint 4 are fixed on the outer wall of the steel needle 5. This fixing method can fix the traction bow 2 and the steel needle 5 without bending the two ends of the traction bow 2, ensuring that the steel needle 5 will not shake during the fixing process, ensuring that the patient will not suffer secondary injuries. At the same time, this fixing method facilitates the operation of medical staff and improves the efficiency of fracture traction.

[0024] The arc-shaped rubber block 7 is fully in contact with the outer wall of the steel needle 5 by squeezing the lower clamp plate 3 and the upper clamp plate 4, and the anti-skid performance of the arc-shaped rubber block 7 itself effectively improves the anti-skid performance of the traction bow 2 and the steel needle 5 after being fixed, preventing the traction bow 2 and the steel needle 5 from slipping, ensuring that there is no compression during the traction process, and reducing the patient's pain. At the same time, when the traction bow 2 needs to be removed after surgery, it can be more convenient without significantly bending the traction bow 2, thereby reducing unnecessary risks.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown, a plurality of mounting holes 14 are respectively provided on the bottom surface of the lower clamping plate 3 and the top surface of the upper clamping plate 4, and rubber mounting blocks 15 are respectively fixed on the two sides away from each other of the two arc-shaped rubber blocks 7, and the rubber mounting blocks 15 are sleeved inside the mounting holes 14, and a plurality of positioning grooves 16 are respectively provided on both sides of the inner wall of the mounting opening 6, and a plurality of positioning blocks 17 are respectively fixed on the left and right sides of the arc-shaped rubber block 7, and the positioning blocks 17 are plugged into the positioning grooves 16, and protective covers 18 are respectively provided at both ends of the steel needle 5, and a rubber ring 19 is fixed inside the protective cover 18, and a plurality of adapter ports 20 are opened on the inner wall of the rubber ring 19 at equal angles.

[0026] During use, after the traction bow 2 and the steel needle 5 are fixed, the medical staff can insert the protective cover 18 into the two ends of the steel needle 5. The protective cover 18 effectively protects the needle tips of the two ends of the steel needle 5 to prevent patients and medical staff from being stabbed, thereby protecting the safety of patients and medical staff. The rubber ring 19 can be bent through the adapter 20 to ensure that the contact area between the rubber ring 19 and the peripheral wall of the steel needle 5 is increased to prevent the protective cover 18 from falling off. The arc rubber block 7 can be replaced by taking the rubber mounting block 15 out of the mounting hole 14, so that different arc rubber blocks 7 can be selected according to the thickness of the steel needle 5, ensuring that the notch opened on the arc rubber block 7 matches the peripheral wall of the steel needle 5. By inserting the positioning block 17 into the positioning groove 16, it can be effectively ensured that the arc rubber block 7 will not be displaced, thereby improving the stability of the arc rubber block 7.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
