Description

Technical Field

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

[0002] Orthopedic traction therapy occupies an important position in the field of orthopedics. It has extremely high requirements for operating tables. Traditional operating tables are often unable to meet the needs of these difficult surgeries. The emergence of orthopedic surgical traction beds just solves this problem. The existing common shoulder and hip joint traction devices generally adopt separate designs to perform traction on different parts.

[0003] For example, a common shoulder joint traction device includes a bracket, a traction arm and a fixed arm. The bracket adopts a C-shaped structure, with the upper end connected to the traction arm and the lower end connected to the fixed arm. The patient needs to choose the appropriate traction force according to his or her own situation. However, this shoulder joint traction device is large in size and heavy in weight, and is not convenient for standing use. It is mainly used for bedside treatment.

[0004] The mainstream hip traction device mainly includes a base and two brackets fixed on the base. The brackets are provided with limiters for fixing the feet. The patient fixes both feet on the limiters for training, which makes it difficult to perform complex movements under certain conditions, and the clinical effect is limited. At the same time, the overall structure is relatively bulky and cannot stand, and it is not convenient to perform exercise exercises anytime and anywhere.

[0005] In addition to their respective usage restrictions, traditional single-function designs adopt a single-function approach, which can neither meet the needs of different joint training at the same time nor achieve multi-joint compound training, which has a certain impact on clinical workflow and efficiency. Specifically, traditional designs require a single medical institution to be equipped with multiple sets of single products that match different parts to support the treatment needs of different directions such as shoulder joints and hip joints. This not only increases procurement costs and warehouse management difficulties, but also makes it easier to confuse product usage due to the large number of models. At the same time, since each single product needs to be configured independently, it takes up more treatment resource space and is difficult to share and reuse resources. This means that when maintaining the same treatment capabilities, single designs will generate more repeated investment. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1: As shown in the figure, an orthopedic traction device includes a base frame 1, and also includes a support rod 2, a telescopic rod 3, an upper limb restraint 4 and a foot restraint 5. The support rod 2 is fixed on the base frame 1, and one end of the telescopic rod 3 is hinged to the upper end of the support rod 2. An adjustment support mechanism 6 for adjusting the pitch angle of the telescopic rod 3 is also provided between the telescopic rod 3 and the support rod 2. The telescopic rod 3 has a cavity 7, and a traction rope 8 is connected in the cavity 7. One end of the traction rope 8 is connected to the upper limb restraint 4, and the other end of the traction rope 8 is connected to a counterweight 9. A pillar 10 is connected to the base frame 1, and the foot restraint 5 is connected to the pillar 10.

[0024] Embodiment 2: As shown in the figure, different from Embodiment 1, the adjusting support mechanism 6 includes an adjusting cylinder 11, a cylinder body of the adjusting cylinder 11 is hinged on the side wall of the support rod 2, and a rod body of the adjusting cylinder 11 is hinged on the lower end of the telescopic rod 3.

[0025] In the above structure, the cylinder body of the adjusting cylinder 11 is connected to the side wall of the support rod 2 by a hinged manner, and the rod body is hinged to the lower end of the telescopic rod 3. This design enables the adjusting cylinder 11 to drive the telescopic rod 3 to change its angle relative to the support rod 2 under the relative movement of the cylinder body and the rod body. The specific working principle is: when the pitch angle of the telescopic rod 3 needs to be adjusted, the cylinder body and the rod body of the adjusting cylinder 11 are controlled to be extended and retracted, thereby changing the relative displacement between the two. Since the cylinder body and the rod body are hinged to the support rod 2 and the telescopic rod 3 respectively, this displacement change is transmitted between the support rod 2 and the telescopic rod 3, so that the telescopic rod 3 changes its angle relative to the support rod 2.

[0026] In this embodiment, the adjusting cylinder 11 may be in the form of an electric cylinder or a damping cylinder with a limiting device.

[0027] In this embodiment, the base frame 1 includes a cross bar 12 and two support rods 13. The two support rods 13 are connected to the cross bar 12, and there is an angle between the two support rods 13. A connecting rod 14 is fixed between the two support rods 13. Universal wheels 15 are respectively fixed to the lower ends of the cross bar 12 and the two support rods 13.

[0028] In the above structure, there is a certain angle between the two support rods 13, and they are fixedly connected by the connecting rod 14, forming an open "human" shaped support structure. This structural design increases the supporting area of ​​the base frame 1 and lowers the center of gravity, providing a more solid supporting foundation for the entire device and greatly improving the stability of the structure. The lower ends of the cross bar 12 and the two support rods 13 are respectively equipped with universal wheels 15 with brakes, so that the entire base frame 1 structure has good mobility. When the position of the device needs to be adjusted, only appropriate push and pull forces need to be applied. With the help of the free rotation of the universal wheels 15, the entire device can be easily translated in any direction, avoiding cumbersome transportation and installation.

[0029] In this embodiment, the support rod 2 is tilted and fixed on the connecting rod 14 , and a reinforcing rod 16 is connected between the side wall of the support rod 2 and the corresponding support rod 13 .

[0030] In the above structure, the support rod 2 is fixed on the connecting rod 14 in an inclined manner rather than being installed vertically. This inclined installation makes the force on the support rod 2 more uniform, reduces the risk of twisting and deformation of the rod body, and thus improves the supporting capacity. At the same time, the setting of the inclination angle also increases the supporting area of ​​the support rod 2 projected on the ground, and improves the device's ability to resist external forces. A reinforcing rod 16 is additionally provided between the side wall of the support rod 2 and the corresponding support rod 13. The reinforcing rod 16 firmly connects the support rod 2 and the support rod 13 to form an overall triangular force-bearing structure, which can disperse and transmit various loads and torques to a great extent, making the entire base structure more solid and reliable.

[0031] From the working principle point of view, during traction training, the traction force of the upper and lower limbs will be transmitted to the base frame 1 through the support rod 2. The inclined installation design of the support rod 2 enables it to better disperse and transmit these forces to both sides of the base frame 1, avoiding excessive concentration of load on a single point; and the presence of the reinforcing rod 16 connects the two support rods 13 and the support rod 2 at the bottom of the base frame 1 into a whole, so that the entire base frame 1 structure can collaboratively share and resist external forces, ensuring the high stability of the device.

[0032] Embodiment 3: As shown in the figure, the difference from Embodiment 2 is that a plurality of pulleys 17 are fixed in the cavity 7 , and the traction rope 8 is wound between the plurality of pulleys 17 .

[0033] In the above structure, the provision of multiple sets of pulleys 17 reduces the friction resistance of the traction rope 8 inside the telescopic rod 3, so that the traction rope 8 can move more smoothly along the rod body. Under the guidance of the pulley 17, the traction rope 8 can effectively avoid direct friction with the inner wall of the rod body, which greatly reduces the movement resistance and is beneficial to improving the traction efficiency. In addition, the guiding effect of the pulley 17 also ensures that the traction rope 8 maintains a relatively fixed direction during movement, avoiding accidents such as entanglement and knotting of the traction rope 8 inside the rod body. This not only ensures the continuity of traction, but also helps to reduce the incidence of accidents and ensure treatment safety.

[0034] In this embodiment, a sleeve 18 is fixed to the bottom of the pillar 10 . The sleeve 18 can be horizontally slidably disposed on the support rod 13 , and a locking bolt 19 is provided between the sleeve 18 and the support rod 13 .

[0035] In the above structure, the sleeve 18 can slide freely along the support rod 13, and the fixed structure of the bottom of the pillar 10 and the sleeve 18 allows the horizontal position of the pillar 10 to be continuously adjusted within a certain range according to needs. This flexible and adjustable advantage enables the device to adapt to the heights of different patients and improves versatility. A locking bolt 19 is provided between the sleeve 18 and the support rod 13. After adjusting to the desired position, the sleeve 18 can be firmly fixed to the support rod 13 by tightening the bolt. It is not only easy to operate, but more importantly, it can effectively prevent the sleeve 18 from slipping during training, thereby ensuring the stability of the position of the pillar 10 and the foot restraint 5, and providing reliable protection for the patient's safe training.

[0036] In this embodiment, a telescopic bracket 20 is connected to the foot restraint 5 , a connecting piece 21 is fixed to the bottom of the telescopic bracket 20 , and the connecting piece 21 is connected to the top of the telescopic bracket 20 through an adjusting bolt assembly 22 .

[0037] In the above structure, by operating the adjusting bolt assembly 22, the angle of the connecting piece 21 at the top of the bracket can be controlled, thereby changing the pitch angle of the telescopic bracket 20. When the front end of the telescopic bracket 20 rises or falls, the foot restraint 5 fixedly connected thereto will also undergo a pitch movement accordingly, and the angle will change accordingly. Medical staff can accurately adjust the pitch angle of the restraint by rotating the adjusting bolt according to the specific situation of the patient, so that it can achieve the optimal treatment position, thereby meeting the individual differences of different patients.

[0038] Embodiment 4: As shown in the figure, different from Embodiment 3, the telescopic bracket 20 includes a first rod body 23 and a second rod body 24, the second rod body 24 is slidably arranged in the first rod body 23, and a plurality of gear holes 25 are equidistantly arranged on the side wall of the first rod body 23, and a positioning hole 26 is arranged on the side wall of the second rod body 24, and the positioning hole 26 is connected to the corresponding gear hole 25 by a positioning bolt 27.

[0039] The telescopic bracket 20 consists of a first rod body 23 and a second rod body 24, and the second rod body 24 can be slidably nested in the inner cavity of the first rod body 23. This nested and sliding design allows the relative position of the two rod bodies to be freely adjusted, thereby realizing the variable length of the entire bracket. In order to firmly lock the rod body position after adjusting to the required length, a plurality of gear holes 25 are equidistantly arranged on the side wall of the first rod body 23, and corresponding positioning holes 26 are opened on the side wall of the second rod body 24. By aligning the positioning hole 26 with a certain gear hole 25 and inserting a positioning bolt 27 from the side to lock it, the two rod bodies can be firmly fixed in this position. This locking principle is simple and reliable, and the operation is extremely convenient. It only needs to slide along the side wall of the rod body to find the appropriate gear hole 25 position, and then buckle the positioning bolt 27 and twist it to complete the locking. No other special tools are needed, which greatly reduces the difficulty of maintenance operations.

[0040] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
