Description

Technical Field

[0001] The present application relates to the technical field of spinal orthopedic structures, and in particular to a lying-sitting traction type spinal orthopedic device. Background Art

[0002] Traction as a preoperative treatment method for spinal correction surgery has been widely recognized by scholars. Many studies have confirmed that continuous traction has a significant effect on the improvement of severe scoliosis. Spinal traction before spinal osteotomy and correction fusion can, on the one hand, gradually loosen the soft tissue contracture on the concave side through slow and continuous traction, improve the rotational deformity of the vertebral body and pedicle, and partially correct severe scoliosis deformity before surgery. On the other hand, longitudinal continuous spinal traction can stretch the spine, especially for patients with thoracic deformity, which helps to improve chest deformity. Combined with systematic cardiopulmonary function training during traction, it can effectively improve cardiopulmonary function and improve patients' tolerance to anesthesia and surgery. The deformity correction effect brought about by continuous traction of the spine before surgery is obtained when the patient is in a clear state of consciousness. Close observation of neurological function during traction helps the surgeon to better understand the patient's spinal nerve tolerance, helps to assess the occurrence of neurological complications and the risk of intraoperative neurological injury, and has a certain degree of foresight for the occurrence of related complications.

[0003] At present, the commonly used spinal traction methods in clinical practice include supracondylar traction (HFT) of the skull and femoral cranium, gravity traction (HGT) of the skull and pelvic traction (HPT), each of which has its own advantages and disadvantages. Taking the skull and pelvic traction (HPT) as an example, Levine first used the skull and pelvic traction device for the treatment of congenital scoliosis in 1969. By the 1970s, O'Brien et al. reported 118 cases of patients with scoliosis treated with the skull and pelvic traction device. Since then, the skull and pelvic traction technology has gradually been mastered by spinal surgeons. The skull and pelvic traction device is light, and patients can move freely and perform preoperative cardiopulmonary function exercises during wearing. It has little impact on patients' daily life and has high patient compliance. However, the existing skull and pelvic traction device is usually only used when the patient is sitting in a wheelchair. It is not applicable to patients standing or lying, resulting in the inability of the existing skull and pelvic traction device to provide treatment in different patient postures.

[0004] Therefore, the prior art still needs to be improved and developed. Utility Model Content

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0043] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides a lying and sitting traction type spinal correction device for performing spinal traction training on patients. For the convenience of structural description, the front of the patient when standing is the front, the back is the back, the opposite directions of the head and feet are the up-down direction, and the opposite directions of the left and right hands are the left-right direction. All structures in this embodiment are described with reference to the above directions.

[0044] like Figure 1, Figure 2 , Figure 3 As shown, the lying and sitting traction type spinal correction device in this embodiment mainly includes: a backrest frame 100, a traction bracket 200, a head traction piece 210, a seat frame 300 and a lower limb support frame 400. The backrest frame 100 is used to connect the patient's back. For example, by installing a strap on the backrest frame 100 and tying it to the patient's body through the strap, the backrest frame 100 can be fixed on the patient's back. By fixing with the strap, the position of the backrest frame 100 on the patient can be fixed. In addition, in the standing state, the entire spinal correction device can still be bound to the patient, and the patient's head can be continuously pulled through the head traction piece 210. The traction bracket 200 is adjustable along the length direction on the backrest frame 100. The length direction in this embodiment refers to the up and down direction. The traction bracket 200 is used to connect the backrest frame 100 and the head traction piece 210, and the height of the head traction piece 210 can be adjusted through the length direction, so that it can adapt to different postures of the patient, such as sitting posture, lying posture and standing posture. The head traction member 210 is connected to the traction support 200 and is used to connect and pull the patient's head. The head traction member 210 can use the existing head-pelvis ring traction structure to pull the patient's head. The seat frame 300 is movably connected to the backrest frame 100 and can be adjusted to form a certain angle with the backrest frame 100, such as 90 degrees to 180 degrees. Figure 1 As shown, when the patient is in a sitting position, it can be 90°; Figure 2 As shown, when the patient is in a lying position, it can be 180°. Of course, its angle can be adjusted to other angles according to different needs. The lower limb support frame 400 is movably connected to the seat frame 300 and can be adjusted to form a certain angle with the seat frame 300, such as 90 degrees to 180 degrees. When the patient is in a sitting position, it can be 90°; Figure 3As shown, when the patient is in a lying position, it can be 180°. Of course, its angle can be adjusted to other angles according to different needs. Therefore, the backrest frame 100, the seat frame 300 and the lower limb support frame 400 can be adjusted to have a lying state, a sitting state and a standing state. In the lying state, the backrest frame 100, the seat frame 300 and the lower limb support frame 400 can be 180° in the horizontal direction, so as to form a bed surface, so that the patient can lie on the device. At this time, the head traction member 210 pulls the patient's head in the horizontal direction through the action of gravity. In the sitting state, the backrest frame 100, the seat frame 300 and the lower limb support frame 400 are 90° respectively, so as to form a seat surface, so that the patient can sit on the device. At this time, the head traction member 210 pulls the patient's head in the up and down directions through the action of gravity. In the standing state, the backrest frame 100, the seat frame 300 and the lower limb support frame 400 can be 180° in the up and down direction, so as to form a backrest support structure, so that the patient can be supported by the rear device during walking. At this time, the head traction part 210 pulls the patient's head in the up and down direction through the action of gravity.

[0045] The lying and sitting traction type spinal correction device in this embodiment connects the backrest frame 100 to the patient's back, so that the traction bracket 200 supports the head traction member 210, and the head traction member 210 is connected to the patient's head to achieve traction on the patient's head. The seat frame 300 and the lower limb support frame 400 are adjustable, so that the entire spinal correction device has a lying state, a sitting state and a standing state. In the sitting state, the lying state and the standing state, the head of the patient can be pulled by the head traction member 210. Compared with the existing head-pelvic ring traction device that can only pull the patient's head while sitting in a wheelchair, this device can allow the patient to achieve as much long-term traction as possible when converting the three body positions of sitting→standing→lying, ensuring that the traction time is long enough to make adequate preparations for the operation.

[0046] like Figure 1 As shown, further, the backrest frame 100 in this embodiment is provided with a shoulder fixing portion 110, and the shoulder fixing portion 110 is used to connect the patient's shoulder so that the backrest frame 100 is limited on the patient's body, so that the head traction member 210 pulls the patient's head. In the specific structure, the shoulder fixing portion 110 can be a shoulder strap, which is tied to the patient's shoulder position through the shoulder strap, for example, like carrying a mountaineering bag, so that the backrest frame 100 and the patient's shoulder position are fixed. The part below the shoulder is fixed, and when the head is pulled, the displacement of the body part below the shoulder is not large, and the traction of the neck is better achieved.

[0047] like Figure 1 , Figure 2As shown, further, the head traction member 210 in this embodiment specifically includes: a head ring 211, a pulling rope 212 and a counterweight 213. A head fixing member is connected to the head ring 211, the head ring 211 is put on the patient's head and fixed, the pulling rope 212 is connected to the head ring 211 and passes through the traction bracket 200, and the counterweight 213 is connected to the pulling rope 212 to pull the head ring 211. The head ring 211, the pulling rope 212 and the counterweight 213 form an existing head-basin ring traction structure, and the pulling rope 212 slides on the traction bracket 200 through a fixed pulley, so that the head ring 211 is pulled under the gravity of the counterweight 213, thereby pulling the patient's head. In the sitting state and the standing state, one end of the pulling rope 212 connected to the head ring 211 pulls the patient's head in the up and down direction, and one end of the pulling rope 212 connected to the counterweight 213 pulls the patient's head in the up and down direction. In the lying state, one end of the pulling rope 212 connected to the head ring 211 pulls the patient's head in the horizontal direction, while one end of the pulling rope 212 connected to the counterweight block 213 pulls the patient's head in the up-down direction.

[0048] like Figure 1 , Figure 2 , Figure 3 As shown, further, the backrest frame 100 and the seat frame 300 in this embodiment are connected through the first seat recliner 120, and the backrest frame 100 adjusts the angle between the seat frame 300 and the seat frame 300 through the first seat recliner 120. The first seat recliner 120 has an angle adjustment function, which can adjust the angle between the backrest frame 100 and the seat frame 300 between 90° and 180°. The first seat recliner 120 can adopt an existing seat back angle adjuster. For example, various car seat back angle adjusters or office seat back angle adjusters. These are all devices that can be purchased on the existing market, and no specific structural description is given.

[0049] like Figure 1 , Figure 2 , Figure 3 As shown, further, the seat frame 300 in this embodiment is connected to the lower limb support frame 400 through the second seat recliner 310, and the seat frame 300 adjusts the angle between the lower limb support frame 400 and the seat frame 300 through the second seat recliner 310. The structure of the second seat recliner 310 is the same as that of the first seat recliner 120, so that the angle between the seat frame 300 and the lower limb support frame 400 can be adjusted between 90° and 180°.

[0050] Through the combined action of the first seat angle adjuster 120 and the second seat adjuster, the backrest frame 100, the seat frame 300 and the lower limb support frame 400 can be adjusted to 180° in the horizontal direction, thereby forming a lying state. An angle close to 90° can be formed between the backrest frame 100 and the seat frame 300, and an angle close to 90° can be formed between the seat frame 300 and the lower limb support frame 400, thereby forming a sitting state, and the patient can sit on the device for traction. The backrest frame 100, the seat frame 300 and the lower limb support frame 400 can be adjusted to 180° in the up and down direction, thereby forming a standing state. The backrest frame 100, the seat frame 300 and the lower limb support frame 400 are all located at the back of the patient, supporting the traction bracket 200 and the head traction member 210, so that traction training can be achieved for the patient in a standing position.

[0051] like Figure 1 As shown, further, in this embodiment, a pelvic fixing assembly 330 is provided on the seat frame 300, and the pelvic fixing assembly 330 is used to connect to the patient's waist and hips, so that the patient's buttocks are restricted on the seat frame 300. In the specific structure, the pelvic fixing assembly 330 can use a strap with a plug buckle, and the part below the pelvis is fixed by the strap. When the head is pulled, the displacement of the body part below the pelvis is not too large, and the traction of the spine is better achieved.

[0052] The shoulder fixing part 110 and the pelvic fixing assembly can keep the relative position of the patient and the skull traction member 210 limited, and can prevent the patient's body from making a large displacement during the traction process. In particular, for some patients with skull base depression, by fixing the relative position of the patient and the skull traction member 210, more precise traction can be achieved, thereby achieving a better treatment effect.

[0053] like Figure 1 , Figure 2 , Figure 3 As shown, further, in this embodiment, a folding pedal 421 is provided on the lower limb support frame 400, and the folding pedal 421 can be folded and arranged at one end of the lower limb support frame 400 away from the seat frame 300. The folding pedal 421 is hinged at the lower end of the lower limb support frame 400. In the sitting state, the folding pedal 421 can be opened, so that the patient can use it to step on the feet in the sitting state. In the lying state and the standing state, the folding pedal 421 can be folded and retracted, so as not to affect the placement of the patient's feet in the lying posture and the standing posture.

[0054] like Figure 1 , Figure 2 , Figure 3As shown, further, in this embodiment, the lower limb support frame 400 is also provided with an auxiliary wheel 422, which is rotatably arranged at one end of the lower limb support frame 400 away from the seat frame 300. The auxiliary wheel 422 is installed at the lower end of the lower limb support frame 400 and can be arranged at the rear of the lower limb support frame 400. In the standing state, the auxiliary wheel 422 can roll on the ground, thereby supporting the movement of the entire spinal orthosis device. When the patient is walking, the patient's body does not need to support the entire spinal orthosis device, thereby facilitating the movement of the patient.

[0055] like Figure 1 , Figure 3 As shown, further, the lower limb support frame 400 in this embodiment specifically includes: a lower limb support fixed frame 410 and a lower limb support movable frame 420. The lower limb support fixed frame 410 is connected to the lower limb support frame 400 through the second seat angle adjuster 310, the lower limb support movable frame 420 is telescopically connected to the lower limb support fixed frame 410, the folding pedal 421 is connected to the lower limb support movable frame 420, and the auxiliary wheel 422 is connected to the lower limb support movable frame 420. The lower limb support movable frame 420 can extend and shorten the entire lower limb support frame 400 through movement. In the specific structure, the left and right sides of the lower limb support fixed frame 410 are set as support tubes, and the left and right sides of the lower limb support movable frame 420 are set as plug rods, which are inserted into the support tube by the plug rods, and the insertion depth is different to achieve extension and contraction. In addition, in order to fix the extension position, a locking screw is provided through the side wall of the support tube, and the plug rod in the support tube can be loosened or compressed by twisting the locking screw. By setting the lower limb support frame 400 as a telescopic structure, it can be adapted to patients of different heights, so that the patient can match the length of the lower limb support frame 400 whether standing or sitting, which makes the use of the spinal orthosis device more convenient.

[0056] like Figure 1 , Figure 4 As shown, further, the lying-sitting traction type spinal correction device in this embodiment also includes: a wheelchair body 600. The wheelchair body 600 is used in a sitting state. The wheelchair body 600 is detachably connected to the seat frame 300 through a locking assembly 500, and the wheelchair body 600 is used to push the patient by connecting to the seat frame 300. When the patient wants to sit down for traction training, the backrest frame 100, the seat frame 300 and the lower limb support frame 400 are formed into a sitting state through the joint action of the first seat angle adjuster 120 and the second seat adjuster. At this time, the seat frame 300 is connected to the wheelchair body 600 through the locking assembly 500, so that a wheelchair structure can be formed, so that the patient can be pushed after sitting down. The wheelchair body 600 may include a wheelchair frame and wheels below. When the seat frame 300 is fixed to the wheelchair body 600, the auxiliary wheel 422 can act on the front wheelchair wheel for use.

[0057] like Figure 1 , Figure 5 As shown, further, the lying and sitting traction type spinal correction device in this embodiment also includes: a bed 700, and the bed 700 is used in a lying state. In the lying state, the bed 700 is detachably connected with the seat frame 300, the back frame 100 and the lower limb support frame 400 respectively through the locking assembly 500, and the bed 700 is used to support the patient by connecting with the seat frame 300, the back frame 100 and the lower limb support frame 400. When the patient wants to lie down for traction training, the back frame 100, the seat frame 300 and the lower limb support frame 400 are formed into a lying state through the joint action of the first seat angle adjuster 120 and the second seat adjuster. At this time, the seat frame 300, the back frame 100 and the lower limb support frame 400 are respectively connected to the wheelchair body 600 through the locking assembly 500, so that a sleeping bed structure can be formed, so that the patient can lie down and perform traction training. The bed body 700 may include a bed frame, and the left and right sides of the seat frame 300, the backrest frame 100 and the lower limb support frame 400 may all be installed on the bed frame.

[0058] like Figure 1 , Figure 5 , Figure 6 As shown, further, a locking groove 320 is provided on the seat frame 300 in this embodiment. The locking assembly 500 in this embodiment specifically includes: a shaft 510, a handle 520 and a locking block 530. The shaft 510 is passed through the bed body 700, the handle 520 is arranged at one end of the shaft 510, and the locking block 530 is arranged at the other end of the shaft 510. Figure 6 As shown in (b), the locking block 530 is inserted into the notch of the locking groove 320 and is driven by the handle 520 to rotate into the locking groove 320. Figure 6 As shown in (a), the handle 520 drives the locking block 530 to rotate, so that the locking block 530 can be rotated into the locking groove 320 to achieve quick connection; the locking block 530 can also be rotated out of the notch of the locking groove 320 to achieve quick disassembly.

[0059] The locking assembly 500 used for the detachable installation of the wheelchair body 600 and the seat frame 300 is the same as the locking structure used for the bed body 700.

[0060] In summary, a lying and sitting traction type spinal orthosis device of the present application realizes traction on the patient's head by connecting the backrest frame to the patient's back, so that the traction bracket supports the skull traction member, and the skull traction member is connected to the patient's head, and the seat frame and the lower limb support frame are adjustable, so that the entire spinal orthosis device has a lying state, a sitting state and a standing state. In the sitting state, the lying state and the standing state, the head of the patient can be pulled by the skull traction member. Compared with the existing head-pelvic ring traction device that can only pull the patient's head while sitting in a wheelchair, this device can allow the patient to achieve as much long-term traction as possible when the three body positions are converted from sitting to standing to lying, ensuring that the traction time is long enough and making adequate preparations for the operation. In order to achieve more precise traction, the shoulder fixing part is set to fix the part below the shoulder. When the skull is pulled, the displacement of the body parts below the shoulder is not large, so the traction of the neck is better achieved. By setting up the pelvic fixing component, the part below the pelvis is fixed. When the head is pulled, the displacement of the body part below the pelvis is not too large, so the traction of the spine is better achieved.

[0061] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
