[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Reference Figure 1-4 The traction device for lumbar surgery shown comprises a waist fixing belt 1 and a chest fixing belt 2, wherein an adjustable supporting structure 3 is connected between the waist fixing belt 1 and the chest fixing belt 2.

[0026] Specifically, the adjustable support structure 3 includes a hydraulic telescopic rod 31, and an operating controller 6 electrically connected to the hydraulic telescopic rod 31 is installed on the waist fixing belt 1. After the patient wears the waist fixing belt 1 and the chest fixing belt 2, the operating controller 6 is used to control the extension of the hydraulic telescopic rod 31, thereby pushing the chest fixing belt 2 upward, and stopping after pushing it to a suitable position. The operation is convenient and reliable, and the applicability is stronger. It should be further explained that the extension length of the hydraulic telescopic rod 31 needs to be determined according to the patient's own comfort state and doctor's advice.

[0027] Among them, in order to facilitate the adjustment of the position of the hydraulic telescopic rod 31 according to one's own needs, the upper and lower ends of the hydraulic telescopic rod 31 are fixedly connected with sliding sleeves 7, and the two sliding sleeves 7 are respectively slidably sleeved on the outside of the waist fixing belt 1 and the chest fixing belt 2. When in use, the sliding sleeves 7 can be used to slide on the waist fixing belt 1 and the chest fixing belt 2 to adjust the hydraulic telescopic rod 31 to be evenly distributed on both sides of the waist, which is more applicable.

[0028] Among them, a fixing structure 4 is provided at both ends of the waist fixing belt 1 and the chest fixing belt 2. Optionally, for example, the fixing structure 4 adopts a fleece-surface Velcro 41 and a hook-surface Velcro 42. The fleece-surface Velcro 41 and the hook-surface Velcro 42 are respectively provided at both ends of the waist fixing belt 1 and the two ends of the chest fixing belt 2. The fleece-surface Velcro 41 and the hook-surface Velcro 42 are bonded to each other to achieve the fixation of the waist fixing belt 1 and the chest fixing belt 2, which is easy to operate.

[0029] Among them, a shoulder positioning component 5, preferably a shoulder strap, is fixedly connected to the waist fixing belt 1. Preferably, two shoulder straps are provided, and the two shoulder straps are symmetrically fixedly connected to the waist fixing belt 1 about the middle part of the waist fixing belt 1. Furthermore, an adjustment part 51 is connected to the shoulder strap to adjust the length of the shoulder strap.

[0030] When wearing, the traction device can be hung on the shoulders using the shoulder straps, and then the fleece-surface Velcro 41 and the hook-surface Velcro 42 are bonded to each other, so that the waist fixing belt 1 and the chest fixing belt 2 are both fixed at the waist position of the body; when taking off, first open the waist fixing belt 1 and the chest fixing belt 2, and then remove the shoulder straps from the shoulders; through the setting of the shoulder straps, the traction device is not easy to accidentally fall to the ground when putting on and taking off, and it is more convenient to wear. In addition, when traction is not needed, the traction device can be hung on the shoulders using the shoulder straps, which is easy to carry, and the length of the shoulder straps is adjustable, which is suitable for people of different heights.

[0031] Furthermore, a storage pocket 11 is fixedly connected to the outer side of the waist fixing belt 1, which is convenient for placing mobile phones, documents and other items.

[0032] There are multiple ventilation holes 8 evenly arranged on the waist fixing belt 1 and the chest fixing belt 2. For the fixing belt with a larger width, the ventilation holes 8 can allow the skin covered by the fixing belt to ventilate, making it more comfortable to wear.

[0033] Among them, multiple protrusions 9 are evenly arranged on the inner sides of the waist fixing belt 1 and the chest fixing belt 2. The multiple protrusions 9 are spaced apart from the multiple ventilation holes 8. The protrusions 9 can be made of skin-friendly and comfortable materials, such as silicone material. The setting of the protrusions 9 can play a certain massage role on the one hand, and on the other hand, it can play an anti-slip role, effectively preventing the waist fixing belt 1 and the chest fixing belt 2 from shifting during use.

[0034] The working principle of the utility model is as follows: when wearing, the traction device can be hung on the shoulder by the shoulder strap, and then the sliding sleeve 7 can be used to slide on the waist fixing belt 1 and the chest fixing belt 2, and the hydraulic telescopic rod 31 can be adjusted to be evenly distributed on both sides of the waist, and then the fleece-surface Velcro 41 and the hook-surface Velcro 42 can be bonded to each other, so that the waist fixing belt 1 and the chest fixing belt 2 are both fixed at the waist position of the body; when taking off, first open the waist fixing belt 1 and the chest fixing belt 2, and then take the shoulder strap 11 off the shoulder; through the setting of the shoulder strap 11, the traction device is not easy to accidentally fall to the ground when putting on and taking off, and it is more convenient to wear. In addition, when traction is not needed, the traction device can be hung on the shoulder by the shoulder strap 11, which is easy to carry, and the length of the shoulder strap 11 is adjustable, which is suitable for people of different heights.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
