Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and more specifically to a limb traction and stretching device for traditional Chinese medicine orthopedics. Background Art

[0002] Orthopedics mainly studies and treats fracture injuries, fracture healing, bone and joint injuries and emergency treatment, lower limb injuries, cervical spine injuries and other diseases. During post-operative rehabilitation in orthopedics, it is often necessary to use traction and stretching devices to pull or stretch the patient's limbs so that the patient can passively move the injured part, or perform activity training on the joints of non-injured parts to prevent thrombosis and help recovery.

[0003] The Chinese invention patent with publication number CN111956382A discloses an orthopedic traction bed, wherein a flip bed board that can be flipped upward is hinged on the rear side of the fixed bed board, a closing plate that can move to the rear side of the interior of the bed body is installed in the key-shaped groove, and a limiting column that can move to the inner side of the key-shaped groove as the closing plate moves is installed on the front side of the interior of the bed body, and guard plates that can be flipped upward as the closing plate moves are hinged on the left and right sides of the fixed plate, and foldable traction frames are installed on the inner sides of the two guard plates respectively; when in use, the device can block the patient by resting against the patient's perineum to restrict the patient's body and prevent the patient's body from shifting when the patient's limbs are pulled; when the closing plate moves to the rear side, the guard plates on both sides will flip upward to a vertical state, and the traction frames on the inner sides of the guard plates can be unfolded and assembled according to the needs of the user, so that the user can install the device for pulling the patient's limbs conveniently.

[0004] It can be seen that the current orthopedic traction devices usually adopt a linear installation and stretching method, which makes it impossible to adjust the angle according to the specific condition of the disease when some patients need to adjust the angle, such as spinal curvature.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are only examples. The limb traction and stretching device for traditional Chinese medicine orthopedics involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0028] Reference Figure 1 , 2 and Figure 3The present invention provides a limb traction and stretching device for traditional Chinese medicine orthopedics, comprising a traction bed body 1, the traction bed body 1 comprising a bed body main body 101, a first bed board 4, a second bed board 8 and a third bed board 9 are installed on the top of the bed body main body 101, the first bed board 4 and the second bed board 8 are installed on a sliding groove 102 through a slide plate, two leg main frames 2 are installed on the side of the traction bed body 1, a rotating bracket 3 is installed on the top of the leg main frame 2, a moving hole 103 is opened on the side of the traction bed body 1, a control component 5 is installed inside the moving hole 103, a first stretching frame 10 is installed on the other side of the bed body 101, the first stretching frame 10 comprises a first fixed frame 1001 and a transverse connecting frame 1002, the bottom of the transverse connecting frame 1002 is installed on the locking frame 104, and a telescopic knob 1003 is installed on the outer side of the transverse connecting frame 1002, and the height of the first fixed frame 1001 is adjusted by rotating the telescopic knob 1003;

[0029] In this embodiment, it should be specifically explained that the third bed board 9 is composed of a headrest 901 and a telescopic rod 902. When the stretching angle of the upper part of the patient needs to be adjusted, the telescopic rod 902 is started to cooperate with the telescopic knob 1003 to control the stretching angle of the patient.

[0030] The main difference between this embodiment and the prior art is that in this embodiment, the synchronous adjustment of the fixed position and the stretching position is achieved by utilizing the change in the position of the patient's foot, and the angle change and high accuracy of the traction position are achieved, specifically, the rotating bracket 3, the control assembly 5, and the second stretching frame 6;

[0031] The above structure is the main structure of this embodiment, which solves the problem that segmented traction and stage traction cannot be realized at present. The traction bed body 1 is an existing structure, and the specific structure and connection method of the traction bed body 1 are not described in detail in this embodiment.

[0032] Reference Figure 4 The transmission rod 15 is composed of a threaded rod, a gear and a pulley. The bottom of the gear is meshed and connected with the transmission component 11. The threaded rod is installed inside the first threaded hole 502. A clutch is installed inside the gear. The installation method and control method of the clutch belong to the prior art and are not elaborated in detail in this application.

[0033] In this embodiment, it is necessary to specifically explain that: when the position of the leg main frame 2 needs to be adjusted, the clutch controls the transmission rod 15 to be connected to the control component 5, and the control component 5 is driven by the threaded rod to control the horizontal movement of the leg main frame 2. When the first position needs to be stretched, the clutch controls the transmission rod 15 to be connected to the second stretching frame 6, and the second spiral rod 504 is controlled by the belt to rotate inside the second stretching frame 6 to realize the control of the position of the second stretching frame 6.

[0034] Reference Figure 5The control component 5 includes a first sliding plate 501 and a second screw rod 504. The side of the first sliding plate 501 is installed inside the second screw rod 504. A first threaded hole 502 is opened on the right side of the first sliding plate 501. The transmission rod 15 is installed inside the first threaded hole 502. The first sliding plate 501 is located on both sides of the first threaded hole 502 and has auxiliary tooth plates 503. The auxiliary tooth plates 503 are meshed and connected with the first gear 1403. A threaded groove is opened at one end of the second screw rod 504, and a first pulley 505 is installed at the other end. The first pulley 505 is connected to the transmission rod 15 through a belt.

[0035] In this embodiment, it should be specifically explained that the control component 5 supports the leg main frame 2. When the leg main frame 2 moves horizontally and expands its width, the first sliding plate 501 and the second spiral rod 504 apply torque to the leg main frame 2 to keep it in a horizontal state.

[0036] Reference Figure 6 The leg main frame 2 includes a leg moving plate 201, a rotating circular groove 202 and a positioning hole 203 are opened inside the leg moving plate 201, a connecting component 14 is installed inside the positioning hole 203, a rotating bracket 3 is installed inside the rotating circular groove 202, and the rotating bracket 3 includes a rotating frame 301, a top of the rotating frame 301 is fixedly connected with an upper cover plate 303, the leg rod 302 and the upper cover plate 303 are fixedly connected by bolts, a fixing frame is installed on the side of the leg rod 302, the fixing frame fixes the stretching point strap at the second position, and the traction of the second position is achieved by moving the leg main frame 2, a belt groove is opened on the outside of the rotating frame 301, and a belt is installed inside the belt groove to connect with the connecting component 14.

[0037] In this embodiment, it should be specifically explained that: the synchronous rotation of the rotating bracket 3 and the connecting component 14 realizes the synchronous change of the angle and width, so that when the patient's foot is placed on the leg rod 302, the unfolding angle of the foot is proportional to the distance between the two leg rods 302, which facilitates the patient to achieve multi-angle traction.

[0038] Reference Figure 7The second stretching frame 6 includes a stretching movable plate 601, a threaded plate 602 is fixedly connected to the bottom of the stretching movable plate 601, a threaded hole is provided inside the threaded plate 602, one end of the transmission rod 15 is installed inside the threaded hole, a plurality of connecting grooves 603 are provided on the top of the stretching movable plate 601, and both ends of the strap assembly 12 are installed inside the connecting groove 603. The strap assembly 12 includes a traction strap 1201, and both ends of the traction strap 1201 are fixedly connected to the strap buckle 1202. A spacing groove 1203 is provided on the front of the strap buckle 1202, and a plurality of first slots are provided at the bottom of the spacing groove 1203. A lifting block 13 is installed at the bottom, and a connecting control rod 7 is installed on the side inside the connecting groove 603. The connecting control rod 7 is composed of a pressing block 701 and a locking block 702. The locking block 702 is installed on the front of the spacing groove 1203. A plurality of second slots are opened on the locking block 702. A return spring is sleeved on the outer side of the pressing block 701. When the strap buckle 1202 is pressed down, the two slots are staggered, so that the strap buckle 1202 can descend normally. After the spacing groove 1203 enters the connecting groove 603, the return spring makes the first slot coincide with the second slot. At this time, the strap buckle 1202 cannot be pulled out, thereby fixing the strap assembly 12.

[0039] In this embodiment, it is necessary to specifically explain that: the lifting block 13 is composed of a trapezoidal block and a second spring. When the strap assembly 12 needs to be unlocked, the end of the pressing block 701 is pressed, and the pressing block 701 applies pressure to the return spring. The first slot and the second slot are interlaced again, and the strap buckle 1202 automatically rises under the action of the second spring, thereby realizing the pop-up of the strap buckle 1202.

[0040] The second stretching frame 6 and the strap assembly 12 constitute a first traction assembly, and the patient's first traction position is fixed on the second stretching frame 6 through the strap assembly 12, and the traction and stretching of the patient's first position are achieved by the movement of the second stretching frame 6. It should be noted that the first stretching position and the second stretching position are located at different positions of the patient's body, and different pulling forces are achieved through different fixed positions and different stretching controls, thereby achieving different and precise control at multiple angles and multiple points.

[0041] Reference Figure 8 The connecting component 14 includes a connecting shaft 1401, and the outer side of the connecting shaft 1401 is fixedly connected with a second pulley 1402 and a first gear 1403. The second pulley 1402 and the rotating frame 301 are connected by a belt to maintain coaxial rotation. The first gear 1403 is meshed and connected with the auxiliary gear plate 503. When the rotating bracket 3 rotates, the belt drives the connecting component 14 to rotate, thereby realizing the position adjustment of the leg main frame 2.

[0042] In this embodiment, it should be specifically explained that: the connecting shaft 1401 is installed inside the positioning hole 203, rolling bearings are installed at both ends of the connecting shaft 1401, and the relative position of the connecting shaft 1401 and the leg main frame 2 is fixed.

[0043] Working principle of the present invention:

[0044] The main problem solved by this embodiment is: using the change in the patient's foot position to achieve synchronous adjustment with the fixed position and the stretching position, achieving higher accuracy of the traction position, and solving the problem that the current segmented traction and stage traction cannot be achieved. At the same time, the third bed board 9 and the first stretching frame 10 are used to achieve the lifting and fixing of the head, solving the current problem that the traction of the patient in different positions and directions cannot be achieved, and achieving more accurate and wide-range traction angles.

[0045] The specific steps are as follows:

[0046] The patient lies on the traction bed body 1, with the head placed on the headrest 901 and the feet placed on the leg rod 302. The transmission assembly 11 is started, and the transmission assembly 11 drives the transmission rod 15 to rotate through the gear. Since the transmission rod 15 is provided with a thread groove and is installed inside the first threaded hole 502, when the gear rotates, the control assembly 5 moves to one side of the leg main frame 2 under the drive of the transmission rod 15 until the leg rod 302 moves to the patient's ankle. At this time, the rotating frame 301 is rotated according to the patient's stretching position and angle, and the belt installed on the inner side of the rotating frame 301 drives the connecting assembly 14 to rotate through the second pulley 1402. Since the first gear 1403 is meshed with the auxiliary gear plate 503, relative movement occurs between the leg main frame 2 and the control assembly 5 at this time, and the leg moving plate 201 moves to the two ends of the first sliding plate 501. The width between the two leg main frames 2 is continuously increased until the heel is located at the top of the leg rod 302, and the upper cover plate 303 is fixed to fix the patient's foot position;

[0047] At this time, the strap is installed. The strap at the first position is composed of the strap assembly 12. The two ends of the strap assembly 12 are pressed inside the connecting groove 603. Since the first slot of the spacing groove 1203 is staggered with the second slot of the locking block 702, the strap assembly 12 is fixed by the locking block 702 and cannot be moved again. At this time, the patient's first fixed position is bound. The second position is fixed to the fixing frame on the side of the leg rod 302 using the strap in the prior art. After the fixation is completed, the transmission assembly 11 is started again. With the transmission of the gear, the leg main frame 2 drives the rotating bracket 3 to the side again. The second screw rod 504 is moved to the side to realize the traction of the second fixed position of the patient. Since the transmission rod 15 is located inside the gear and a clutch is installed, when the second position needs to be stretched, the clutch is started to connect the pulley on the transmission rod 15 with the transmission assembly 11. When the transmission assembly 11 is started again, the pulley drives the first pulley 505 to rotate, thereby realizing the rotation of the second screw rod 504. Since the second screw rod 504 is provided with a thread groove and is installed inside the threaded plate 602, the second screw rod 504 drives the second stretching frame 6 to move sideways to realize the stretching of the first position.

[0048] When the head stretching angle needs to be adjusted, the telescopic rod 902 and the telescopic knob 1003 are activated, the telescopic rod 902 raises the headrest 901, the patient's upper body is tilted, and the telescopic knob 1003 raises the position of the first fixing frame 1001, and then the two ends of the traditional strap are respectively fixed to the patient's lumbar spine and the side of the first fixing frame 1001. At this time, since the patient's upper body is in a tilted state, the change in angle can promote the adjustment of the traction angle of the patient's vertebrae and adapt to the traction positions of different vertebrae.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
