[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. Generally, the components of the embodiments of this application described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0048] In the description of this application, it should be noted that the orientation or positional relationship indicated by terms such as "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of this application is usually placed. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application. In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0049] In the description of this application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] An embodiment of this application provides an orthopedic nursing traction bracket, which includes a fixing bracket 100, a mandibular support 210, and a buffer member 300.

[0051] The fixing bracket 100 has a base frame body 110 fixedly arranged and a telescopic frame body 120 that can be lifted and telescoped on the base frame body 110; exemplarily, as Figure 1 shown, the base frame body 110 is fixedly arranged on the seat 610, and the patient can sit on the seat 610 for neck traction. However, in another embodiment, the base frame body 110 is fixedly arranged on the ground, and the patient performs neck traction in a standing position.

[0052] Exemplarily, the base frame body 110 is vertically arranged.

[0053] Exemplarily, the telescopic frame body 120 is in sliding telescopic cooperation with the base frame body 110, and the telescopic frame body 120 can move up and down on the base frame body 110.

[0054] Exemplarily, the driving structure for driving the telescopic frame body 120 to move up and down on the base frame body 110 is, for example, a hydraulic telescopic driving mechanism, a pneumatic telescopic driving mechanism, a threaded lead screw telescopic driving structure, an electric push rod telescopic driving mechanism, or a rack and pinion telescopic driving mechanism, etc. Alternatively, the telescopic frame body 120 and the base frame body 110 are configured as an active telescopic mechanism, such as a hydraulic telescopic mechanism, a pneumatic telescopic driving mechanism, or an electric push rod telescopic driving mechanism, etc.

[0055] The mandibular support 210 provides a placement position for the patient's mandible. The mandibular support 210 is provided on the telescopic frame body 120, and the telescopic movement of the telescopic frame body 120 drives the mandibular support 210 to move up and down. During use, the patient's mandible is placed on the placement position of the mandibular support 210.

[0056] The buffer member 300 includes a support frame 330, a first elastic member 310, and a buffer plate 320.

[0057] The support frame 330 is provided on the base frame body 110.

[0058] The first elastic member 310 can stretch and rebound and is provided between the support frame 330 and the buffer plate 320. Exemplarily, the first elastic member 310 includes, but is not limited to: a helical spring, a corrugated spring, a butterfly spring, a leaf spring, a leaf spring, a rubber spring, an air spring, etc.

[0059] The buffer plate 320 is located on the movement path of the mandibular support 210 and below the gravity direction of the mandibular support 210.

[0060] During use, when the telescopic frame body 120 extends, it drives the mandibular support 210 to rise. The rise of the mandibular support 210 drives the stretching of the patient's neck. The first elastic member 310 pushes the buffer plate 320 towards the mandibular support 210, causing the buffer plate 320 to abut against the mandibular support 210. When the telescopic frame body 120 shortens, the mandibular support 210 and the patient's head drop in height under the action of gravity. During the descent of the mandibular support 210, it abuts against the buffer plate 320. The mandibular support 210 descends and presses down on the buffer plate 320. The mandibular support 210 and the patient's mandible exert a force on the buffer plate 320 through the mandibular support 210, causing the buffer plate 320 to move downward. The first elastic member 310 contracts. The first elastic member 310 weakens the impact on the buffer plate 320 during the descent of the mandibular support 210 and exerts a reaction force on the mandibular support 210 through the buffer plate 320. Under the action of the buffer plate 320 and the first elastic member 310, it can ensure that the inertia received by the patient's cervical vertebra is reduced and prevent damage.

[0061] In the present application, the provided mandibular support 210 provides a stable placement position for the patient's mandible, enabling the patient to maintain a comfortable posture during cervical traction implementation.

[0062] In the present application, the first elastic member 310 and the buffer plate 320 in the buffer member 300 can effectively weaken the impact on the buffer plate 320 during the descent of the mandibular support 210, and exert a reaction force on the mandibular support 210 through the buffer plate 320, thereby reducing the inertial impact on the patient's cervical vertebrae, preventing injury, and improving the safety of the treatment process. Moreover, the buffer member 300 can support the patient's mandible when the connection between the mandibular support 210 and the telescopic frame body 120 fails, preventing the patient's neck from being sprained and improving the safety of the treatment process.

[0063] In some embodiments, the mandibular support 210 is directly connected to the telescopic frame body 120. However, in another embodiment, as Figure 1 shown, the mandibular support 210 is connected to the telescopic frame body 120 through a connecting member 220. The lifting of the telescopic frame body 120 drives the lifting of the connecting member 220, and the lifting of the connecting member 220 drives the lifting of the mandibular support 210; Exemplarily, the connecting member 220 is, for example, a rigid member or a flexible member that can stretch and rebound. The rigid member is, for example, a steel cable, a nylon rope, etc., and the flexible member is, for example, an elastic rubber rope, a spiral spring rope, etc.

[0064] As Figures 1 to 3 shown, in one embodiment, a spreading frame 600 is further provided between the mandibular support 210 and the connecting member 220. The connecting member 220 is connected to the mandibular support 210 through the spreading frame 600, and the spreading frame 600 spreads the mandibular support 210 to facilitate the placement of the patient's mandible on the mandibular support 210.

[0065] As Figure 3 、 Figure 7 or Figure 8 shown, in one embodiment, the orthopedic nursing traction bracket further includes a fixing band 410. The fixing band 410 is detachably mounted on the mandibular support 210. A receiving channel for accommodating the patient's neck is provided between the fixing band 410 and the mandibular support 210. The fixing band 410 is used to fix the patient's posterior occiput. The fixing band 410 pushes against the patient's posterior occiput, thereby making the patient's head approach the mandibular support 210, so that the patient's mandible fits more closely with the mandibular support 210.

[0066] Exemplarily, the detachable connection form between the fixing band 410 and the mandibular support 210 is, for example, a magic tape 540a, a buckle, an adhesive, etc.

[0067] Exemplarily, the fixing band 410 is in an arc structure. One end of the fixing band 410 is detachably mounted on one end of the mandibular support 210, and the other end of the fixing band 410 is detachably mounted on the other end of the mandibular support 210.

[0068] In this application, the design of the fixing strap 410 can effectively fix the posterior occipital part of the patient. By pushing the posterior occipital part of the patient, the patient's head is brought closer to the mandibular support 210, so that the patient's mandible fits more closely with the mandibular support 210. This design ensures the stability of the patient's head during traction and prevents the traction effect from being affected by head shaking or deviation.

[0069] In this application, a receiving channel for accommodating the patient's neck is provided between the fixing strap 410 and the mandibular support 210. This design takes into account the physiological curve of the patient's neck, reduces the pressure of the fixing strap 410 on the patient's neck, and improves the comfort of the patient.

[0070] In this application, by fixing the patient's head on the mandibular support 210 with the fixing strap 410, the accurate transmission of the traction force can be ensured, the accuracy of the traction effect is improved, and the treatment effect is enhanced.

[0071] As Figure 3 and Figure 7 shown, in one embodiment, the orthopedic nursing traction bracket further includes a temperature adjusting member 420. The temperature adjusting member 420 is used to adjust the temperature of the fixing strap 410 and the temperature of the posterior occipital part of the patient, improving the comfort during traction. The fixing strap 410 provides an installation base for the temperature adjusting member 420, and the temperature adjusting member 420 is arranged on the side wall of the fixing strap 410 close to the mandibular support 210.

[0072] Exemplarily, the temperature adjusting member 420 is a heater, and the heater includes but is not limited to: resistance heater, electromagnetic heater, chemical reaction heater (such as warm baby, also known as warm patch, which is a disposable heating product, and its working principle is based on the galvanic cell effect, converting chemical energy into heat energy by accelerating the oxidation reaction of iron powder with oxygen in the air) or infrared heater, etc.

[0073] In another embodiment, the temperature adjusting member 420 is a cooler, and the cooler includes but is not limited to: ice storage box, fan, cooling pipe, etc. In another embodiment, the temperature adjusting member 420 is an integration of a heater and a cooler.

[0074] In this application, the temperature adjusting member 420 can adjust the temperature of the fixing strap 410 and the temperature of the posterior occipital part of the patient, so that the patient feels a more comfortable environment during traction. Whether it is heating or cooling, it can be adjusted according to the actual needs of the patient to meet personalized requirements.

[0075] In this application, appropriate temperature stimulation can promote blood circulation in the posterior occipital part and neck of the patient, help relieve muscle tension and pain, and accelerate the patient's recovery process. For example, the heating function can promote blood circulation and relieve muscle stiffness; the cooling function can provide a cool feeling in hot weather, reducing sweating and discomfort.

[0076] In this application, the temperature adjustment member 420 is designed such that the orthopedic care traction bracket can adapt to the changes in different seasons and climates. In the cold winter, the heating function can provide warmth for the patient; in the hot summer, the cooling function can bring coolness to the patient, improving the usage experience.

[0077] As Figure 3 and Figure 7 shown, in one embodiment, the temperature controller 430 of the temperature adjustment member 420 is arranged on the fixing band 410, so that the patient or doctor can directly operate on the fixing band 410 without the need to search for or move other components additionally, greatly improving the convenience of adjusting the temperature.

[0078] As Figure 3 and Figure 7 shown, in one embodiment, the orthopedic care traction bracket further includes an isolation member 440. The isolation member 440 is arranged on the fixing band 410, and the temperature adjustment member 420 is located between the isolation member 440 and the fixing band 410.

[0079] Exemplarily, the isolation member 440 is detachably mounted on the fixing band 410, and the detachable connection form is, for example, Velcro, snap fastener, adhesive, etc.

[0080] Exemplarily, the isolation member 440 can prevent the temperature adjustment member 420 from directly contacting the patient's skin; the isolation member 440 can evenly conduct the heating effect or cooling effect of the temperature adjustment member 420. When the isolation member 440 is in direct contact with the patient's skin, it can improve the temperature control effect of the temperature adjustment member 420. When the temperature adjustment member 420 is a heater, the isolation member 440 can prevent the temperature adjustment member 420 from directly contacting the patient's skin when the temperature rises too fast or is too high, avoiding scalding.

[0081] In one embodiment, the support frame 330 is foldably mounted on the base frame 110, so that the support frame 330 can be unfolded or folded on the base frame 110.

[0082] When the support frame 330 is unfolded, the buffer member 300 is in the working position, and when the support frame 330 is folded, the buffer member 300 is in the storage position.

[0083] Exemplarily, the support frame 330 is a telescopic mechanism. One end of the support frame 330 is disposed on the base frame 110, and a first elastic member 310 and a buffer plate 320 are disposed on the other end of the support frame 330. The support frame 330 extends to unfold relative to the base frame 110. The extension of the support frame 330 drives the first elastic member 310 and the buffer plate 320 to move, so that the buffer plate 320 is located on the moving path of the lower jaw support 210 and below the gravity direction of the lower jaw support 210, thereby enabling the buffer member 300 to be in the working position. The support frame 330 contracts to fold relative to the base frame 110. The contraction of the support frame 330 drives the first elastic member 310 and the buffer plate 320 to move away from the lower jaw support 210, thereby reducing the space occupied by the orthopedic nursing traction bracket and facilitating storage and transportation.

[0084] Different from the technical solution in the above embodiment where the support frame 330 is a telescopic mechanism, as Figures 1 to 3 shown, in another embodiment, the support frame 330 further includes a first sub-frame 331, a second sub-frame 332, and a support plate 333.

[0085] One end of the first sub-frame 331 is hingedly connected to the base frame 110, and the base frame 110 is vertically arranged; one end of the second sub-frame 332 is hinged to the other end of the first sub-frame 331.

[0086] The support plate 333 is connected to the second sub-frame 332. One end of the first elastic member 310 is connected to the support plate 333, and the other end of the first elastic member 310 is connected to the buffer plate 320.

[0087] Exemplarily, the support plate 333 is fixedly connected to the second sub-frame 332 through a plate body.

[0088] The working process of adjusting the buffer member 300 to the working position is as follows: As Figure 1 or Figure 3 shown, the first sub-frame 331 rotates in a direction perpendicular to the base frame 110 to unfold the first sub-frame 331 relative to the base frame 110. When the first sub-frame 331 rotates to the horizontal state, it drives the second sub-frame 332 to rotate to the horizontal state; As Figure 1 or Figure 3 shown, the second sub-frame 332 can rotate and fold on the first sub-frame 331 in a direction close to the lower jaw support 210. The rotation of the second sub-frame 332 drives the buffer plate 320, the first elastic member 310, and the support plate 333 to rotate, so that the buffer plate 320 is located on the moving path of the lower jaw support 210 and below the gravity direction of the lower jaw support 210, thereby enabling the buffer member 300 to be in the working position.

[0089] The working process of adjusting the buffer member 300 to the storage position is as follows: As Figure 2As shown, the second sub-frame 332 rotates and unfolds on the first sub-frame 331 in a direction away from the lower jaw support 210, making the second sub-frame 332 parallel to the first sub-frame 331; the first sub-frame 331 can rotate and fold on the base frame 110 in a direction parallel to the base frame 110, so that the first sub-frame 331 folds onto the base frame 110; the folding of the first sub-frame 331 drives the second sub-frame 332 to approach the base frame 110, thereby placing the buffer member 300 in the storage position.

[0090] It can be understood that in the above two working processes, the sequence of actions of the first sub-frame 331 and the second sub-frame 332 can be swapped.

[0091] In one embodiment, a reinforcing rib is provided at the connection between the support plate 333 and the second sub-frame 332. Exemplarily, at least one reinforcing rib is provided. When more than two reinforcing ribs are provided, the reinforcing ribs can be distributed on the same side or evenly distributed on both sides.

[0092] In one embodiment, a T-shaped guiding post 570 is vertically provided on the support plate 333. The two ends of the T-shaped guiding post 570 are respectively a column end and a protruding end; the column end is fixedly installed on the support plate 333, and a sliding through hole is provided on the buffer plate 320. The column end is slidably matched with the inner wall of the sliding through hole of the buffer plate 320. The radial cross-sectional area of the protruding end is larger than the radial cross-sectional area of the sliding through hole. The protruding end is used to limit the buffer plate 320 to prevent the buffer plate 320 from slipping off the T-shaped guiding post 570, and the column end guides the buffer plate 320 to move along the axis direction of the column end.

[0093] Exemplarily, the buffer plate 320 is rectangular, and a sliding through hole is provided at each of the four corners of the buffer plate 320, and four T-shaped guiding posts 570 are correspondingly provided. Of course, the sliding through holes of the buffer plate 320 and the T-shaped guiding posts 570 can also be provided with other numbers, such as two, three, five or six, etc.

[0094] As Figure 5 As shown, in one embodiment, a first limiting plate 334 is provided at the hinge joint between the first sub-frame 331 and the base frame 110. The first limiting plate 334 is provided on the movement path when the first sub-frame 331 unfolds. When the first sub-frame 331 unfolds to be perpendicular to the base frame 110, it abuts against the first limiting plate 334, and the first limiting plate 334 blocks the first sub-frame 331 to keep the first sub-frame 331 perpendicular to the base frame 110.

[0095] Exemplarily, as Figure 5As shown, a hinged mounting seat 560 is fixedly arranged on the base frame 110, and the fixing method is, for example, welding, riveting, bolt connection or clamping, etc. The first sub-frame 331 is hingedly mounted on the hinged mounting seat 560 on the base frame 110, so as to realize the hinged mounting of the first sub-frame 331 on the base frame 110.

[0096] Exemplarily, as Figure 5 shown, a first limiting plate 334 is horizontally and fixedly arranged on the hinged mounting seat 560, and the fixing method is, for example, welding, clamping, bolt connection or integral molding, etc. When the first sub-frame 331 is unfolded to be perpendicular to the base frame 110, it abuts against the first limiting plate 334, and the first limiting plate 334 blocks the first sub-frame 331 to keep the first sub-frame 331 perpendicular to the base frame 110.
