Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically relating to a cervical traction device. Background Technology

[0002] Cervical traction devices, as a common medical rehabilitation device, are widely used in the conservative treatment of cervical diseases such as cervical spondylosis and herniated discs. They relieve pressure on the intervertebral space and correct physiological curvature by applying longitudinal traction force. Traditional cervical traction devices usually adopt a circumferential neck fixation design, that is, they apply traction force to the neck through components such as chin rests and occipital support straps.

[0003] However, this design has the following drawbacks: because the traction force acts directly on the soft tissues and areas with dense distribution of blood vessels and nerves in the neck, prolonged use can easily lead to compression of major blood vessels such as the carotid artery and vertebral artery, increasing the risk of insufficient blood supply to the brain. For patients with underlying conditions such as arteriosclerosis, stenosis, or hypertension, this compression effect may further aggravate vascular endothelial damage and even induce ischemic stroke, severely limiting the range of suitable patients.

[0056] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0057] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0058] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0059] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0060] The core treatment mechanism of cervical traction devices is to apply controllable longitudinal traction force to the cervical spine to increase the intervertebral space volume, reduce intradiscal pressure, release nerve root adhesions, and gradually restore the normal physiological curvature of the cervical spine. Current mainstream traditional cervical traction devices form a traction structure around the neck using components such as a chin rest, occipital support belt, headrest bracket, and lateral abdominal binder. The neck is a densely distributed area of ​​key structures such as the carotid artery, vertebral artery, jugular vein, and brachial plexus. The circumferential restraint structure of traditional traction devices inevitably causes intermittent compression of blood vessels, easily leading to the risk of insufficient blood supply to the brain. Therefore, it is unsuitable for patients with underlying diseases such as arteriosclerosis, stenosis, or hypertension. Furthermore, the force points of traditional traction devices are mostly concentrated on the mandible and posterior neck muscles, easily causing local muscle fatigue, temporomandibular joint soreness, and compressive pain, resulting in a very poor user experience and potentially causing discomfort such as difficulty breathing. Based on the above-mentioned technical problems, this application provides a cervical traction device, which is equipped with a molar support plate for traction, shifting the point of application of traction force from the neck to the upper jaw, completely avoiding the dense distribution area of ​​blood vessels and nerves in the neck, eliminating the potential risks caused by mechanical compression of the blood vessel adventitia, meeting the needs of patients with arteriosclerosis and hypertension, expanding the applicable population, and improving the comfort of using the cervical traction device.

[0061] Please refer to the attached document as well. Figure 1 To be continued Figure 9 The cervical traction device provided by this utility model will now be described. The cervical traction device includes a traction mounting component 01, a connecting component, a molar support plate 09, a palatal positioning component, and a strap 07. The traction mounting component 01 is fixed by the connecting component, thereby fixing the molar support plate 09 and the palatal positioning component. The molar support plate 09 supports the user's molar area upwards to achieve a traction effect. Specifically, the traction mounting component 01 is suitable for vertical fixation. One end of the connecting component is fixed to the traction mounting component 01, and the other end is suitable for connecting to a fixed object, or the connecting component is used to fix the traction mounting component 01 to a support frame. The molar support plate 09 and the palatal positioning component are respectively fixedly mounted on the traction mounting component 01. The molar support plate 09 has a supporting portion suitable for insertion into the oral cavity to support the molars, and the palatal positioning component is positioned above the molar support plate 09 to abut against the front of the user's palate. The strap 07 is sleeved on the traction mounting component 01 and is suitable for limiting the user's head. When the user is positioned between the molar support plate 09 and the maxillary positioning component and the head is restrained by the strap 07, the body is suspended on the traction mounting piece 01 to achieve cervical traction. After the user fixes the head on the traction mounting piece 01, he / she can squat down to achieve the effect of suspension traction.

[0062] In this embodiment, the point of application of traction force is cleverly transferred to the molar area, which completely avoids the mechanical compression of the vascular and nerve structures in the carotid triangle, eliminates the risk of cerebral blood supply disorders that are easily caused by traditional mandibular traction, and significantly improves the comfort of patients wearing it.

[0063] In one implementation, please refer to the appendix as well. Figure 1 To be continued Figure 7 A wall or door frame can be selected as the fixing object for securing the traction mounting component 01. The other end of the connector is adapted to fix the traction mounting component 01 to the door frame or wall. The user bends their knees and is suspended from the door frame, wall, or support frame by the mounting component to achieve cervical traction. The traction mounting component 01 is a rod-shaped structure or a hollow tubular structure, with multiple first mounting holes 011 arranged along the length of the traction mounting component 01. Different heights of the first mounting holes 011 are selected for assembly with the connector, thereby adjusting the height of the traction mounting component 01. Among them, the connector, molar support plate 09, maxillary positioning component, and strap 07 are respectively assembled at different heights of the traction mounting component 01.

[0064] For further details, please refer to the appendix. Figure 5 The maxillary positioning assembly includes two symmetrically arranged maxillary positioning members 08. Specifically, the two maxillary positioning members 08 are symmetrically arranged with reference to the vertical midline of the traction mounting member 01. The molar support plate 09 is located in the middle of the traction mounting member 01 and below the maxillary positioning members 08, ensuring that after the user places the molar support plate 09 against the molar, the maxillary positioning members 08 can abut against the front of the maxilla for limiting positioning. Each maxillary positioning member 08 includes an integrally formed assembly part 082 and an abutment part 081. The abutment part 081 has an arc-shaped structure that protrudes towards the front of the user's maxilla. Specifically, the abutment part 081 can be a C-shaped rod structure. The assembly part 082 is provided through the traction mounting member 01 and can be adjusted towards or away from the user, and is positioned and connected to the traction mounting member 01 by means of a nut. Specifically, the assembly part 082 is a screw structure that passes horizontally through the traction mounting part 01. A pair of nuts are threaded onto the assembly part 082, and the two nuts abut against both sides of the traction mounting part 01 to position the upper jaw positioning part 08. Before traction, the user can adjust the extension and retraction of the upper jaw positioning part 08 to ensure that the upper jaw positioning part 08 can form a good limit at the front of the upper jaw.

[0065] In this embodiment, the position of the upper jaw positioning component 08 can be adjusted according to actual needs, which improves the versatility of the product. The upper jaw positioning component 08 works in conjunction with the molar support plate 09 to limit the position, which can ensure the stability of the molar support plate 09 in supporting the head and avoid displacement or damage to the molars during traction.

[0066] Furthermore, the cervical traction device also includes a forehead positioning component 06. The forehead positioning component 06 has a groove on the side facing the user that is suitable for fitting the forehead, and the other side is fixedly connected to the traction mounting component 01. Specifically, the forehead positioning component 06 includes a limiting part and a connecting rod. The limiting part is fixed to the traction mounting component 01 by the connecting rod. The limiting part is a rod-shaped structure or a tubular structure and is recessed towards the user to form a groove suitable for fitting the forehead.

[0067] In this embodiment, by setting a forehead positioning component 06 and cooperating with an upper jaw positioning component 08 to assist in limiting the head, the head is further prevented from shifting during traction, eliminating the risk of sprains and ensuring the stability and safety of the traction process.
