Description

Technical Field

[0001] The invention relates to the field of medical instruments, and in particular to an orthopedic traction frame. Background Art

[0002] Orthopedic traction frames are mainly used for patients' intertrochanteric fracture surgery. Intertrochanteric fractures are common in the elderly. Due to the rich blood supply to the trochanteric area, fractures rarely fail to heal, but hip varus is very likely to occur. Elderly patients with long-term bed rest have more complications.

[0003] Before the operation, the patient needs to sit on the seat board, lean back against the back board, and then put his feet into the foot restraint assembly, and then manually move the foot restraint assembly to open the patient's fracture position to facilitate the doctor to perform the operation. The existing traction frame uses a perineum column as a barrier to prevent the patient from sliding down when the doctor pulls the patient's legs. In actual operation, when the foot restraint assembly is moved manually, the perineum column will squeeze the male perineum. Therefore, the doctor is often unable to accurately open the patient's fracture position due to this reason, which affects the effect of the operation. Summary of the invention

[0004] The purpose of the present invention is to provide an orthopedic traction frame, which can accurately open the fracture position of the patient, and the setting of the friction structure can also avoid the occurrence of squeezing of the male perineum.

[0005] The purpose of the present invention is achieved by the following technical solutions:

DETAILED DESCRIPTION

[0026] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0027] The words expressing positions and directions described in the present invention are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of the present invention.

[0028] An orthopedic traction frame comprises a back plate 1, a seat plate 2, a leg rest 4, a foot restraint assembly 5, an electric drive assembly 6 and a control module.

[0029] like Figure 1 and Figure 2As shown, the backboard 1 is connected to the seat board 2, and the seat board 2 and the backboard 1 are both provided with a friction structure 3. Two leg rests 4 are movably connected to the two sides of the seat board 2, and each leg rest 4 corresponds to a foot restraint assembly 5, which is slidably arranged on the corresponding leg rest 4. Each foot restraint assembly 5 corresponds to an electric drive assembly 6, which is connected to the end of the leg rest 4 away from the seat board 2. The electric drive assembly 6 can be used to drive the foot restraint assembly 5 to slide horizontally along the length direction of the leg rest 4. The control module is connected to the electric drive assembly 6 by signal. In this embodiment, the control module The module is not shown in the figure. Specifically, when the patient sits on the seat board 2 and leans on the back board 1, the doctor can control the electric drive component 6 through the control module to drive the foot restraint component 5 to move horizontally for traction, thereby opening the patient's fracture position and then implanting the intramedullary nail. Since the friction structure 3 is provided on the seat board 2 and the back board 1, the friction structure 3 replaces the traditional perineal column, which can prevent the doctor from sliding down and squeezing the perineum during traction. The control module controls the electric drive component 6 to drive the foot restraint component 5 for traction, which is also more accurate and convenient to operate.

[0030] As a further implementation of this embodiment, the friction structure 3 is uniformly distributed silicone protrusions. The setting of the silicone protrusions can increase the friction with the patient's skin, avoiding the patient from sliding downward during traction. At the same time, the setting of the silicone material can also reduce the patient's discomfort.

[0031] As a further implementation of this embodiment, the seat board 2 has two adjacent recesses 7, and the recesses 7 have a stretchable structure, specifically, a highly elastic material. A weight sensing device 8 is provided in the recess 7, and a driving unit 9 for changing the depth of the recess 7 is also provided below the recess 7. In this embodiment, the driving unit 9 is an electric push rod, and the weight sensing device 8 and the driving unit 9 are both connected to the control module signal. When the patient sits on the seat board 2, the buttocks sink into the recess 7, and the weight sensing device 8 in the recess 7 transmits the weight signal to the control module. After receiving the signal, the control module changes the depth of the recess 7 through the driving unit 9 to adapt to patients of different weights, so that the buttocks of all patients can be deeply sunken in the recess 7, so that the recess 7 forms a damping for the patient when the doctor is pulling, and the patient will not slide downward.

[0032] As a further implementation of this embodiment, the foot restraint assembly 5 includes a hard long boot, which can wrap the patient's calf, providing effective support while reducing the patient's discomfort.

[0033] As a further implementation of this embodiment, the electric drive component 6 includes a linear module 600, which is electrically connected to the control module. The linear module 600 is arranged on the leg rest 4. The linear module 600 has a slide, which is connected to the foot restraint component 5. During operation, the doctor only needs to control the horizontal reciprocating movement of the slide of the linear module 600 through the control module, thereby driving the horizontal movement of the foot restraint component 5 to complete traction. This structure is easy to operate and more precise, while also more labor-saving, and effectively improves the success rate of the operation.

[0034] As a further implementation of this embodiment, the leg rest 4 includes a cross beam 400 and a support column 401. The support column 401 is arranged at the bottom of the cross beam 400 and in contact with the ground. The support column 401 is a retractable structure, and the retractable structure is retracted in the vertical direction. This structure can change the height of the leg rest 4, thereby meeting the surgical needs of doctors of different heights and expanding the scope of application of the device.

[0035] As a further implementation of this embodiment, the beam 400 includes a first sliding column 4001 and a second sliding column 4002. The first sliding column 4001 has a hollow structure inside, and the second sliding column 4002 is slidably connected to the first sliding column 4001. Specifically, the linear module 600 is arranged on the second sliding column 4002, and the slide is exposed from the hollow structure of the first sliding column 4001. The second sliding column 4002 can slide horizontally until part of the structure is exposed from the first sliding column 4001. This structure can meet the traction needs of patients of different heights and expand the scope of application.

[0036] As a further implementation of this embodiment, the orthopedic traction frame includes a universal wheel 10, which is arranged at the bottom of the leg rest 4. The universal wheel 10 has a locking function. The setting of the universal wheel 10 allows the leg rest 4 to be moved at any time. When it is needed, it can be easily moved to be connected to the seat board 2, and when it is not needed, it can be easily moved to be separated from the seat board 2.

[0037] As a further implementation of this embodiment, Figure 3The orthopedic traction frame includes a hand rest 11 and a traction plate 12. The hand rest 11 is movably arranged on the left side of the back plate 1. The traction plate 12 is movably arranged on the right side of the back plate 1 and can extend to the upper side of the back plate 1. The traction plate 12 includes a horizontal plate 120 and a vertical plate 121. The horizontal plate 120 is connected to the vertical plate 121 through a damping hinge. The vertical plate 121 is rotatably connected to the right side of the back plate 1 through a ratchet 13. A limiting member 14 for limiting the clockwise rotation of the vertical plate 121 is provided on the back plate 1. The hand rest 11 is used to place the upper limbs corresponding to the healthy lower limbs. At the same time, it is also convenient for the doctor to observe the infusion situation. The traction plate 12 is used to fix the upper limb corresponding to the fractured lower limb, so as to avoid placing the upper limb on the side of the affected limb to affect the doctor's surgical operation on the affected limb. When a traction plate 12 at a different angle is needed, the horizontal plate 120 is rotated to the right side of the back plate 1, and the traction plate 12 is rotated counterclockwise to the required position, and then the horizontal plate 120 is rotated to reset. When the patient places his hand on the traction plate 12, due to the downward pressure applied by gravity, the limiter 14 can limit the traction plate 12 from rotating clockwise, thereby facilitating the patient to place his arm.
