Description

Technical Field

[0001] The present invention relates to the technical field of orthopedic surgery auxiliary instruments, and in particular to an orthopedic surgery traction system. Background Art

[0002] In orthopedic surgery, especially in the treatment of hip and lower limb fractures, surgical position placement and traction are one of the key factors for the success of the operation. At present, the traditional orthopedic traction bed is commonly used in clinical practice. This type of orthopedic traction bed usually fixes and pulls the patient's affected limb through a complex mechanical structure, while providing intraoperative position stability. The main structure of the traditional orthopedic traction bed includes: a basic operating bed system, an abduction frame for fixing the patient's healthy limb, a traction frame for traction of the affected limb, a foot traction device for adjusting the patient's shortening and dislocation, and a rotational dislocation of the affected limb during surgery. Its working principle is to fix the perineum through a mechanical device, apply appropriate traction force and angle adjustment to the distal end of the fracture, so that the fracture ends remain in a good reduction state during the operation, while providing the surgeon with a clear operating field of view.

[0003] However, this traditional orthopedic surgery traction bed has many problems and shortcomings in practical application: First, the operation is complicated and requires the assistance of multiple people. When placing the patient's position during the operation, after the patient is successfully anesthetized, the traditional orthopedic surgery traction bed usually requires the cooperation of 4-5 medical staff to complete. The structure of the traditional orthopedic surgery traction bed is complex, and the convenience of clinical operation and individual differences of patients are not fully considered. The process of adjusting the position is time-consuming and laborious, which increases the preparation time for surgery; Second, the distal end of the fracture is suspended in the air, resulting in poor alignment. In the design of the traditional orthopedic surgery traction bed, the distal end of the fracture is usually suspended in the air. Although the design of the distal end of the fracture suspended in the air can provide a good operating space for the surgeon, when the traction force is insufficient, it may cause the fracture ends to be angled downward and poorly aligned, and excessive traction may cause the fracture ends to separate, affecting the reduction effect of the fracture; Third, the equipment is large in size and inconvenient to move and operate. The traditional orthopedic surgery traction bed is large in size, occupies the space of the operating room, and is inconvenient to move. At the same time, due to its complex structural design, the maintenance cost is high, and the equipment operation requires special training, which is difficult to promote and use in small hospitals or medical institutions with limited resources.

[0024] like Figures 1 to 7 As shown, an orthopedic surgical traction system of the present invention comprises a support plate 1, a perineum column 2 and a foot traction brace 3. The support plate 1 can be detachably placed flat on an operating table 5. The support plate 1 is provided with a back lying area 11, a perineum limiting area 12, an affected leg supporting area 13 and an affected foot traction area 14 arranged in sequence. The orthopedic surgical patient lies flat on the supporting plane of the support plate 1 and presses the support plate 1 with his own weight. The perineum column 2 can be detachably mounted on the support plate 1. The perineum limiting area 12 is adjustable in its installation position, the perineum column 2 is used to abut and limit the perineum of the orthopedic surgery patient, the affected leg support area 13 of the support plate 1 is used to provide stable support for the distal end of the affected limb fracture of the orthopedic surgery patient, the foot traction brace 3 is detachably installed at the affected foot traction area 14 of the support plate 1 and its installation position is adjustable, the foot traction brace 3 is used to fix the affected foot of the orthopedic surgery patient and apply traction to the distal end of the affected limb fracture.

[0025] By placing the support plate 1 directly on the operating table 5, the orthopedic patient can lie directly on the support plane of the support plate 1 and press the support plate 1 with his own weight, without the need for an additional locking mechanism to lock the support plate 1 on the operating table 5, making it easier and more convenient to use and greatly reducing the time for disassembly and assembly. At the same time, in conjunction with the use of the perineum column 2 and the foot traction brace 3, it can simplify the position fixation and traction operation of the orthopedic patient, avoiding the complex process of multiple medical staff collaborating to position the orthopedic patient, which is beneficial to reducing the manpower and operation time required for the operation and improving the operation efficiency. By placing the support plate 1 with the affected leg support area 13, a stable traction platform can be provided, and traction can be performed on the ordinary operating table 5, which can provide a stable support for the distal end of the affected limb fracture of the orthopedic patient, effectively The problem of the distal end of the fracture being suspended in the air is avoided, thereby ensuring the reasonable distribution of traction force and significantly improving the success rate of fracture reduction; the installation positions of the perineal column 2 and the foot traction brace 3 on the support plate 1 can be flexibly adjusted, and can be accurately adjusted according to the needs of different patients to meet the needs of patients of different body shapes, thereby improving the flexibility and adaptability of the operation; through the coordinated use of the support plate 1, the perineal column 2 and the foot traction brace 3, the installation preparation time of the equipment can be reduced, the surgical preparation process can be simplified, the surgical efficiency can be improved, and the time wasted before the operation can be reduced; in addition, through the coordinated use of the support plate 1, the perineal column 2 and the foot traction brace 3, the design is simple and the manufacturing cost is low. It can be directly used in conjunction with an ordinary operating bed 5 without the need for expensive special equipment, and is convenient for wide promotion and application, especially suitable for medical institutions with limited funds.

[0026] In addition, fixation of the healthy limb of an orthopedic surgery patient can be combined with the use of an abduction frame in the prior art.

[0027] Preferably, the support plate 1 can be made of a light-weight and high-strength material, such as carbon fiber, to effectively reduce the weight of the support plate 1 and effectively ensure the strength of the support plate 1 so that medical staff can easily carry it.

[0028] The orthopedic surgery traction system also includes an anti-lateral deviation column 4, which is used to limit and prevent lateral deviation of one side of the upper body of the orthopedic surgery patient during the traction process. As a result, during the traction process, the upper body of the orthopedic surgery patient can be effectively prevented from deflecting to one side with the perineum column 2 as the rotation fulcrum, so as to effectively ensure the traction effect. The anti-lateral deviation column 4 can be detachably installed in the back lying area 11 of the support plate 1 and its installation position is adjustable. The installation position of the anti-lateral deviation column 4 on the support plate 1 can be flexibly adjusted, and can be accurately adjusted according to the needs of different patients to meet the needs of patients of different body shapes, thereby improving the flexibility and adaptability of the operation.

[0029] In addition, the perineum column 2, the foot traction brace 3 and the anti-lateral deviation column 4 can adjust their installation positions along the width direction or length direction of the support plate 1, thereby effectively ensuring the flexibility of adjusting the installation positions of the perineum column 2, the foot traction brace 3 and the anti-lateral deviation column 4 on the support plate 1 to better meet the needs of patients of different body shapes.

[0030] In addition, the outer circumferences of the perineum column 2 and the anti-lateral deviation column 4 are both provided with a cushion layer to further reduce discomfort during the traction process.

[0031] Preferably, the support plate 1 is a porous plate and is provided with a first mounting through hole 121, a second mounting through hole 141 and a third mounting through hole 111. The support plate 1 is provided with a plurality of the first mounting through holes 121 evenly distributed at the perineum limiting area 12. The bottom end of the perineum column 2 is fixedly provided with a first mounting column 21 adapted to the first mounting through hole 121. The first mounting column 21 is detachably inserted into the first mounting through hole 121. The support plate 1 is provided with a plurality of the second mounting through holes 121 evenly distributed at the affected foot traction area 14. A second mounting through hole 141 is fixedly disposed at the bottom end of the foot traction brace 3 and is adapted to the second mounting through hole 141. The second mounting through hole 141 can be detachably inserted into the second mounting through hole 141. A plurality of third mounting through holes 111 are evenly distributed on the support plate 1 at the back lying area 11. A third mounting through hole 41 adapted to the third mounting through hole 111 is fixedly disposed at the bottom end of the anti-lateral deviation column 4. The third mounting through hole 111 can be detachably inserted into the third mounting through hole 111. By adopting the supporting plate 1 with a porous plate structure, in combination with the arrangement of the plurality of first mounting through holes 121, the plurality of second mounting through holes 141 and the plurality of third mounting through holes 111, the perineum column 2 can be directly inserted into the corresponding first mounting through hole 121 through the first mounting column 21 according to actual needs and conveniently, the foot traction brace 3 can be directly inserted into the corresponding second mounting through hole 141 through the second mounting column 39 according to actual needs and conveniently, and the anti-lateral deviation column 4 can be directly inserted into the corresponding second mounting through hole 141 through the second mounting column 39 according to actual needs and conveniently. The third mounting column 41 is directly inserted into the corresponding third mounting through hole 111, thereby facilitating the flexible adjustment of the mounting positions of the perineum column 2, the foot traction brace 3 and the anti-lateral deviation column 4 on the support plate 1. In addition, a plurality of fourth mounting through holes 131 are evenly distributed on the support plate 1 at the affected leg support area 13. In addition, preferably, the first mounting through hole 121, the second mounting through hole 141, the third mounting through hole 111 and the fourth mounting through hole 131 are all distributed in a rectangular array.

[0032] The support plate 1 is in a rectangular shape, and a rectangular avoidance gap 15 is provided on one side of the affected leg support area 13 and the affected foot traction area 14 on the support plate 1, so that the support plate 1 is in an L shape. The setting of the avoidance gap 15 facilitates the avoidance of the placement of the C-arm fluoroscopy device. The support plate 1 can flip and switch the support planes on its two symmetrical sides to adapt to the use of the left and right affected limbs of orthopedic patients. Correspondingly, the first mounting through hole 121, the second mounting through hole 141, and the third mounting through hole 111 all pass through the two symmetrical support planes on the support plate 1, thereby making the support plate 1 have a bilateral universal design, and can directly adapt to the surgical needs of the left and right affected limbs of orthopedic patients by flipping. At the same time, this design can reduce the time for instrument replacement and adjustment, which is conducive to further simplifying the surgical preparation process, improving the surgical efficiency, and reducing the time waste caused by equipment adjustment before surgery.

[0033] Preferably, the width of the support plate 1 is adapted to the width of the operating bed 5, and at least the back lying area 11, the perineum limiting area 12, and the affected leg supporting area 13 on the support plate 1 are supported on the operating bed 5, thereby ensuring the contact support area between the support plate 1 and the operating bed 5.

The one-way self-locking mechanism 35 is used to play a one-way self-locking role in the movement of the movable mounting seat 33 and allow the movable mounting seat 33 to move to a side away from the fixed mounting seat 32.

[0035] By setting the sliding assembly 37, a relative sliding connection between the movable mounting seat 33 and the fixed mounting seat 32 can be achieved, and a corresponding guiding effect can be played on the movement of the movable mounting seat 33 relative to the fixed mounting seat 32, and the stability and smoothness of the movable mounting seat 33 when sliding can be effectively ensured, so as to effectively ensure the stability and smoothness of the L-shaped supporting shell 31 when moving. When the movable mounting seat 33 is driven by the traction driving mechanism 34 to move relative to the fixed mounting seat 32 and away from the fixed mounting seat 32, the L-shaped supporting shell 31 can be moved relative to the fixed mounting seat 32 and away from the fixed mounting seat 32.

The overall structure is simple and easy to operate.

[0036] When in use, the foot, ankle and calf of the orthopedic surgery patient can be partially wrapped by the L-shaped support shell 31 and then tied and fixed by multiple strap assemblies 36. At the same time, the perineum column 2 can be used to abut and limit the perineum of the orthopedic surgery patient, and the anti-lateral deviation column 4 can be used to limit and prevent lateral deviation on one side of the upper body of the orthopedic surgery patient. When the L-shaped support shell 31 is driven by the traction drive mechanism 34 to move away from the perineum column 2, it can have a corresponding traction effect on the affected limb of the orthopedic surgery patient and provide continuous and stable traction force to the distal end of the fracture. It is simple to operate and easy to use, and can effectively avoid insufficient or excessive traction force, which is beneficial to improving the success rate of fracture reduction.

[0037] Correspondingly, the L-shaped support shell 31 is provided with an L-shaped support cavity 311 adapted to the foot, ankle and calf of the orthopedic surgery patient, so that the inner surface of the L-shaped support cavity 311 can better fit the foot, ankle and calf of the orthopedic surgery patient, which is beneficial to further improve the stability of the connection between the L-shaped support shell 31 and the foot, ankle and calf of the customer's surgery patient.
