Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an orthopedic trauma rehabilitation fixation device. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body, including the required computer software. Their effectiveness is mainly achieved through physical means, not through pharmacological, immunological or metabolic means, or although these means are involved, they only play an auxiliary role. Their purpose is to diagnose, prevent, monitor, treat or alleviate diseases, diagnose, monitor, treat, alleviate or compensate for injuries, inspect, replace, regulate or support physiological structures or processes, support or maintain life, and control pregnancy. They provide information for medical or diagnostic purposes by examining samples from the human body. Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the skeletal muscle system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system.

[0003] At present, the traditional leg fixation devices widely used in clinical practice, although they can meet the fixation needs to a certain extent, have significant limitations. During the trauma rehabilitation stage, the patient’s legs are in a fixed state for a long time, and the activity level is greatly reduced. This situation can easily lead to the problem of slowed blood circulation. As an important pathway for the transport and metabolism of body substances, the slowdown of blood circulation will lead to insufficient oxygen supply to local tissues, obstruction of nutrient delivery, and accumulation of metabolic waste. For the trauma site, poor blood circulation will directly affect the wound healing process, increase the risk of infection, and slow down the repair of bones and soft tissues. Not only that, as the rehabilitation process progresses, the patient’s leg muscles gradually atrophy and the joint flexibility decreases, while traditional devices cannot provide targeted rehabilitation training support and it is difficult to meet the personalized needs of patients at different rehabilitation stages. Therefore, the present invention proposes a trauma rehabilitation fixation device for orthopedics. Summary of the Invention

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] The device of the present invention will be described below in conjunction with preferred embodiments thereof.

[0038] Example 1:

[0039] As attached Figure 1 To the attached Figure 10As shown, the present invention provides an orthopedic trauma rehabilitation fixation device, including a tooling frame 1, wherein two groups of tooling frames 1 are symmetrically arranged on the left and right, and the tooling frames 1 on both sides are horizontally installed through the bottom foot plates 101, and the tops of the tooling frames 1 on both sides are oppositely provided with support plates 102, and the bottom of one side of the tooling frame 1 is provided with a cross bar 103, and a convex plate 2 and a first fixed plate 3 are respectively installed on the support plates 102 on both sides, and a first moving mechanism 4 is provided between the convex plate 2 and the first fixed plate 3, and a second fixed plate 5 is slidably connected to the first moving mechanism 4, and a fixing mechanism 6 is provided on the first fixed plate 3 and the second fixed plate 5, and a second moving mechanism 7 is provided at the bottom of the tooling frames 1 on both sides, and a rehabilitation auxiliary mechanism 8 is slidably connected to the second moving mechanism 7.

[0040] Example 2:

[0041] As attached Figure 5 To the attached Figure 8 As shown, this embodiment is basically the same as the previous embodiment, except that the first moving mechanism 4 includes a first fixed block 401, a first threaded rod 402, a second fixed block 403, a first guide rod 404, a first threaded block 405, a first guide block 406 and a second rocker 407. The first fixed block 401 is arranged at the bottom of the first fixed plate 3, and the first threaded rod 402 is installed between the first fixed block 401 and the convex plate 2. The second fixed block 403 is correspondingly arranged on both sides of the first fixed block 401, and the first guide rod 404 is installed between the second fixed blocks 403 and the convex plate 2 on both sides. The first threaded block 405 and the first guide block 406 are both arranged at the bottom of the second fixed plate 5, and the first threaded block 405 and the first guide block 406 cooperate with the first threaded block 405 and the first guide rod 404 respectively. A second rocker 407 connected to the first threaded block 405 is provided on one side of the first fixed plate 3.

[0042] Furthermore, a sliding groove 301 is opened on the first fixed plate 3, and a bidirectional threaded rod 302 is provided in the sliding groove 301. One end of the bidirectional threaded rod 302 passes through the outside of the first fixed plate 3 and is connected to the first rocker 303. The two sides of the bidirectional threaded rod 302 are threadedly connected to the second threaded block 304.

[0043] Furthermore, the fixing mechanism 6 includes a mounting plate 601 corresponding to the second threaded block 304, an elongated through-hole 602 is provided on the mounting plates 601 on both sides, a second threaded rod 603 is provided on the elongated through-hole 602, an arc-shaped clamping plate 604 is provided on the opposite surfaces of the mounting plates 601 on both sides, a lower pressure rod 605 is slidingly provided on the elongated through-hole 602, and a third threaded block 606 cooperating with the second threaded rod 603 is provided in the grooves on both sides of the lower pressure rod 605, and a lower pressure plate 607 is also provided at the bottom of the lower pressure rod 605. The fixing mechanism 6 also includes a synchronous wheel 608 arranged on the top of the second threaded rod 603, a synchronous belt 609 is wound around the outside of the synchronous wheels 608 on both sides, and a third rocker 610 is connected to the axis of the synchronous wheel 608 on one side.

[0044] As can be seen from the above, when in use, the medical staff rotates the second rocker 407 to drive the first threaded rod 402 to rotate. Since the first threaded block 405 is threadedly engaged with the first threaded rod 402, the rotation of the first threaded rod 402 drives the first threaded block 405 to move laterally. At the same time, the first guide block 406 slides along the first guide rod 404 to ensure that the second fixing plate 5 moves smoothly and linearly. The second fixing plate 5 is adjusted laterally according to the length of the patient's leg until the distance between it and the first fixing plate 3 is adapted to the length of the patient's leg. The patient's thigh is then placed between the arc-shaped splints 604 on the first fixing plate 3. The medical staff rotates the first rocker 303 to drive the bidirectional threaded rod 302 to rotate. Since the second threaded block 304 is threadedly engaged with the bidirectional threaded rod 302, the rotation of the bidirectional threaded rod 302 drives the second threaded blocks 304 on both sides to move in opposite directions. The opposite movement of the second threaded blocks 304 drives the arc-shaped splints 604 to move in opposite directions, and the adjustment is made according to the thickness of the patient's thigh and calf. , providing suitable space for subsequent fixation operations. Then the medical staff rotates the third rocker 610 to drive the synchronous wheel 608 and the synchronous belt 609 to rotate, driving the second threaded rods 603 on both sides to rotate synchronously. Since the third threaded block 606 is threadedly matched with the second threaded rod 603, the rotation of the second threaded rod 603 drives the lower pressure rod 605 to slide down along the elongated through-hole 602, so that the lower pressure plate 607 is pressed down to fix the thigh. Similarly, the patient's calf is placed in the space reserved after the arc splint 604 on the second fixing plate 5 is adjusted. Repeat the above operation and rotate the third rocker 610 to press the lower pressure plate 607 down to fix the calf. The thigh and calf are accurately fixed on the first fixing plate 3 and the second fixing plate 5 respectively to ensure the stability of the wound site.

[0045] Example 3:

[0046] As attached Figure 9 To the attached Figure 10As shown, this embodiment is basically the same as the previous embodiment, except that the second moving mechanism 7 includes a third threaded rod 701, a connecting plate 702, a first motor 703, a third fixed block 704, a second guide rod 705, a threaded connecting rod 706 and a second guide block 707. The third threaded rod 701 is arranged at the bottom of the tooling frame 1, and one end of the third threaded rod 701 is installed in the middle of the cross bar 103. The first motor 703 is fixedly connected to the other end of the third threaded rod 701 through the connecting plate 702. There are four groups of third fixed blocks 704, which are respectively arranged at the top of the foot plate 101. A second guide rod 705 is provided between the third fixed blocks 704 on both sides. The second guide rod 705 is arranged parallel to both sides of the third threaded rod 701. The external thread of the third threaded rod 701 is connected to the threaded connecting rod 706, and both ends of the threaded connecting rod 706 are connected to the second guide block 707 arranged outside the second guide rod 705.

[0047] Specifically, the medical professional activates the first motor 703, driving the third threaded rod 701 to rotate. Because the threaded connecting rod 706 engages with the third threaded rod 701, the rotation of the third threaded rod 701 drives the threaded connecting rod 706 to move axially. Simultaneously, the second guide block 707 slides along the second guide rod 705, ensuring smooth and linear movement of the threaded connecting rod 706. The threaded connecting rod 706 drives the rehabilitation assistive mechanism 8 to move axially along the leg, adapting to the rehabilitation needs of injured areas of different leg lengths.

[0048] Furthermore, the rehabilitation assisting mechanism 8 includes a support frame 801, a fixing member 802, a first gear 803, a second gear 804, a third gear 805, a second motor 806 and a sliding gear buckle 807 arranged on the top of the second guide block 707. The top of the support frame 801 is connected to the fixing member 802, and a group of third gears 805, two groups of first gears 803 and two groups of second gears 804 are rotatably connected to the fixing member 802. The third gears 805 are all engaged with the two groups of second gears 804. The two groups of second gears 805 are engaged with the second gears 804. The wheel 804 is respectively engaged with the two groups of first gears 803, and a second motor 806 is fixedly installed on the outer side of the fixing member 802. The output end of the second motor 806 is fixedly connected to the third gear 805. A sliding tooth buckle 807 is slidably connected inside the fixing member 802. The sliding tooth buckle 807 is engaged with both groups of first gears 803. The rehabilitation assisting mechanism 8 also includes a connecting member 808 and an electric telescopic massage hammer 809. The electric telescopic massage hammer 809 is arranged on the side of the sliding tooth buckle 807 through the connecting member 808.

[0049] Specifically, the medical staff starts the second motor 806 to drive the third gear 805 to rotate, and transmits the rotational motion to the first gear 803 through the three-stage gear transmission chain, driving the sliding tooth buckle 807 to slide in a circle. The moving trajectory of the sliding tooth buckle 807 is precisely controlled by the gear transmission ratio to achieve precise positioning of the electric telescopic massage hammer 809 along the axis of the leg. The medical staff controls the length of the telescopic rod through the built-in motor of the electric telescopic massage hammer 809 and adjusts the contact depth between the massage hammer head and the injured area of ​​the leg. The electric telescopic massage hammer 809 dynamically massages the injured area of ​​the leg along a preset trajectory to promote blood circulation and tissue repair. By adjusting the speed of the second motor 806 and the telescopic frequency of the electric telescopic massage hammer 809, rehabilitation stimulation of different intensities can be achieved.

[0050] As can be seen from the above, the medical staff starts the first motor 703, drives the rehabilitation auxiliary mechanism 8 to move along the axis of the leg to the target trauma area, starts the second motor 806 to drive the electric telescopic massage hammer 809 to move back and forth along the trauma area of ​​the leg contour, controls the length of the telescopic rod of the electric telescopic massage hammer 809, makes the massage hammer head contact the trauma area and applies a preset pressure, starts the vibration function of the massage hammer head, cooperates with the composite movement of the second moving mechanism 7 and the rehabilitation auxiliary mechanism 8, realizes dynamic massage rehabilitation of the trauma area, and realizes spatial coverage and dynamic massage stimulation of the trauma area through the coordinated movement of the second moving mechanism 7 and the rehabilitation auxiliary mechanism 8. This dynamic massage stimulation will cause the blood vessels in the muscle to be squeezed and dilated, thereby accelerating the blood flow, and through continuous and regular light hammering stimulation, it can maintain the basic tension and function of the muscle, prevent excessive degradation of muscle fibers and significant reduction in muscle volume, effectively relieve the patient's pain symptoms, and improve the patient's rehabilitation effect and process comfort.

[0051] Among them, it should be specifically explained that the electric telescopic massage hammer 809 adopts the model NB070D20153.

[0052] When in use, the medical staff rotates the second rocker 407 to drive the first threaded rod 402 to rotate, and the first threaded block 405 moves laterally. At the same time, the first guide block 406 slides along the first guide rod 404 to ensure that the second fixing plate 5 moves smoothly and linearly. According to the length of the patient's leg, the second fixing plate 5 is adjusted to a position at a suitable distance from the first fixing plate 3, and the patient's thigh is placed between the arc splint 604 on the first fixing plate 3. The medical staff rotates the first rocker 303 to drive the bidirectional threaded rod 302 to rotate, driving the second threaded blocks 304 on both sides to move in opposite directions, thereby bringing The movable arc splints 604 move toward each other, and the spacing between the arc splints 604 is adjusted according to the thickness of the patient's thigh to provide appropriate space for subsequent fixation. Then the medical staff rotates the third rocker 610 to drive the synchronous wheel 608 and the synchronous belt 609 to rotate, driving the second threaded rods 603 on both sides to rotate synchronously, and the lower pressure rod 605 slides down along the elongated opening 602 to make the lower pressure plate 607 press down to fix the thigh, and place the patient's calf in the space reserved after the arc splint 604 is adjusted on the second fixing plate 5. Repeat the operation of rotating the third rocker 610 to press the lower pressure plate 607 down to fix the calf. At this point, the thigh and calf are precisely fixed to the first and second fixing plates 3 and 5, respectively, ensuring the stability of the injured area. The medical staff then uses the second moving mechanism 7 to drive the rehabilitation assist mechanism 8 along the leg axis to the target injured area. The medical staff activates the second motor 806, driving the third gear 805 to rotate. Through the three-stage gear transmission chain, the sliding gear 807 slides in a circular motion. The sliding gear 807 drives the electric telescopic massage hammer 809 to precisely position along the leg axis. The medical staff uses the built-in motor of the electric telescopic massage hammer 809 to control the length of the telescopic rod and adjust the contact depth of the massage hammer head with the leg injured area. The electric telescopic massage hammer 809 dynamically massages the injured leg area along a preset trajectory, promoting blood circulation and tissue repair. By adjusting the speed of the second motor 806 and the extension and retraction frequency of the electric telescopic massage hammer 809, different intensities of rehabilitation stimulation can be achieved.
