Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an orthopedic traction frame for orthopedic surgery. Background Art

[0002] Bone traction is one of the treatment methods used by orthopedics for fracture reduction, fixation and many other orthopedic diseases. Traction can be used to achieve the treatment goal, especially for patients who are not suitable for surgery. For patients with leg fractures or other lower limb diseases, it is difficult to move the lower limbs and maintain a posture for a long time, which is not conducive to the rehabilitation of the lower limbs and can easily cause joint stiffness and muscle spasms. In clinical practice, traction frames are often used to help patients with lower limb rehabilitation.

[0003] For example, the patent application document with publication number CN201692024U and announcement date 2011-01-05 discloses a base, an adjusting beam is provided on the base, a sleeve that can slide along the adjusting beam is provided on the adjusting beam, a leg support fixing rod is provided on the sleeve, a leg support adjusting rod is provided in the leg support fixing rod, a leg support is provided on the leg support adjusting rod, a lifting rod is provided on the base, a contact pad is provided on the top of the lifting rod, a sleeve is sleeved in the adjusting beam, a fixing joint is connected to one end of the sleeve, a fixing rod is provided on the fixing joint, a tightener adjusting rod that can slide relatively along the fixing rod is sleeved in the fixing rod, a screw-in device is provided on the top of the tightener adjusting rod, and a shoe cover is provided at one end of the screw-in device. The patient's legs are placed in the leg support, the feet are placed in the shoe covers, and then fixed. The crank is rotated, and the screw-in device pushes the shoe covers to move, so as to position the patient's legs in the horizontal direction. When the utility model is used for surgical operation, medical staff does not need to support the horizontal positioning, thereby improving medical efficiency and reducing the workload of medical staff.

[0004] The above patent manually adjusts the height of the device to achieve traction on the patient's legs, which is convenient for subsequent orthopedic surgery. However, this adjustment method is cumbersome to operate, which prolongs the operation time. The patient stays in one posture for a long time, resulting in poor blood circulation, which can easily affect the effect of the operation.

[0005] In summary, there is an urgent need for an orthopedic traction frame for orthopedic surgery that is easy to operate to solve the above problems. Utility Model Content

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Embodiment: An orthopedic traction frame for orthopedic surgery, such as Figure 1-Figure 4 As shown, it includes a bottom plate 1, a bracket 2, a winding wheel 3, a full gear 4, a motor 5, a limiting wheel 6, a pull rope 7 and a supporting plate 8. The bottom plate 1 is a mounting carrier for parts. The bracket 2 is rotatably welded on the bottom plate 1. A V-shaped opening is opened on the upper part of the bracket 2. The winding wheel 3 is rotatably welded on the middle part of the bracket 2. The full gear 4 is rotatably welded on the lower part of the bracket 2. The two full gears 4 are meshed. The winding wheel 3 rotatably penetrates the bracket 2 and is welded to the full gear 4. The motor 5 is installed on the lower rear side of the bracket 2. The output shaft of the motor 5 is welded to a full gear 4 through a coupling. The limiting wheels 6 are arranged in two groups, each group of limiting wheels 6 has eight limiting wheels 6, and each group of limiting wheels 6 is distributed in an L shape on the left and right sides of the bracket 2. A pull rope 7 is welded on the winding wheel 3, and the other end of the pull rope 7 is wound around the limiting wheels 6. A support plate 8 is welded between the two pull ropes 7, and the support plate 8 is located on the front side of the bracket 2. The pull rope 7 is driven to rotate by starting the motor 5, and then the support plate 8 is driven to move upward to lift the patient's feet to achieve traction. The limiting wheels 6 are used to limit the pull rope 7.

[0022] like Figure 1 As shown, a turning handle 201 is also included, and the turning handle 201 is welded to the lower part of the bracket 2.

[0023] like Figure 2 As shown, a sponge pad 9 is also included, and the sponge pad 9 is welded on the supporting plate 8.

[0024] like Figure 4 As shown, it also includes universal wheels 10, which are four in number and are rectangular and detachably welded to the lower side of the base plate 1.

[0025] like Figure 4 As shown, a mounting plate 11 is also included. The mounting plate 11 is welded symmetrically at the lower part of the base plate 1, and two mounting holes 12 are engraved on the mounting plate 11.

[0026] When the patient needs to use the device for orthopedic surgery, first, the medical staff pushes the bracket 2 to rotate the universal wheel 10 to achieve the displacement of the device. After arriving at the operating room, the medical staff disassembles the universal wheel 10 and uses tools to drive the bolts into the mounting holes 12 on the mounting plate 11 to fix the device to prevent the device from shifting during subsequent operations. The components on the bracket 2 are driven to rotate by turning the handle 201 so that the motor 5 is located in front of the patient. Then, one leg of the patient is placed on the V-shaped opening of the bracket 2 so that the patient's foot is located above the support plate 8. The motor 5 is started, and the output shaft of the motor 5 rotates to drive the full gear 4 to rotate. Since the two full gears 4 are meshed, the two winding wheels 3 are driven to rotate in different directions respectively, and the winding wheel 3 drives the pull rope 7 to rotate. After tightening, the pull rope 7 drives the support plate 8 and the sponge pad 9 to move upward and contact the patient's foot for traction. The limiting wheel 6 plays a limiting function on the pull rope 7. Finally, the patient's foot is pulled to a suitable position and the motor 5 is turned off. The medical staff performs orthopedic surgery on the patient's leg. After completing the traction surgery, the motor 5 is started, and the output shaft of the motor 5 operates in the reverse direction to drive the full gear 4 to rotate, thereby driving the pull rope 7 to rotate in the reverse direction. The support plate 8 and the sponge move downward and separate from the patient's foot. If the patient's other leg also needs traction surgery, just follow the above steps. Finally, the medical staff puts the patient's leg back on the bed, removes the bolts from the mounting holes 12 on the mounting plate 11, reinstalls the universal wheel 10 on the base plate 1, and pushes the bracket 2 to drive other components to shift back to the initial position.

[0027] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
