背景技术Background technique
牵引复位床是用于患者治疗、复位的必不可少的一种医疗设备，其广泛应用于各种人体骨盆部位、下肢部位等腰部以下区域的手术治疗、复位理疗。现有的牵引复位床通常仅配置一条床腿并且通常设置于该牵引复位床的床板的中间位置，由于使用该牵引复位床进行手术治疗或复位理疗的操作区域也通常位于床板的中间位置区域，故而在进行诸如透视操作时极易影响透视效果，并且进一步现有的牵引复位床通常部件/组件配置较多，结构复杂，同时提高了制造成本，并且在实际应用诸如透视操作时进一步加剧影响透视效果；此外，现有的牵引复位床虽然部件/组件配置较多，结构复杂，但是却功能单一，通常仅能够实现一个功能，例如，或仅用于骨盆骨折复位，或仅用于下肢手术牵引等等，并且在实际应用时，现有的牵引复位床通常仅能够实现床板一体升降，也即是说，床头和床尾两边同升或同降，这种结构通常无法满足实际应用需求，无法达到良好的使用效果，或者为了能够实现单边升降，也即是说，床头或床尾单边升或降，将现有的牵引复位床的床板设置为两段式或多段式，但是这种结构进一步增加了现有牵引复位床的部件/组件配置数目，使得现有牵引复位床结构更加复杂，成本进一步增加，操作更加不便；此外，现有的牵引复位床通常均无法实现精确的人体下肢牵引位置/角度微调，故而现有的牵引复位床并未取得意想不到的良好使用效果。The traction reduction bed is an indispensable medical device for the treatment and reduction of patients. It is widely used in the surgical treatment and reduction physiotherapy of various human pelvic parts, lower limbs and other areas below the waist. Existing traction and reduction beds usually have only one bed leg and are usually arranged in the middle of the bed board of the traction and reduction bed. Since the operating area of the traction and reduction bed for surgical treatment or reduction physiotherapy is also usually located in the middle position area of the bed board, Therefore, it is very easy to affect the fluoroscopy effect when performing fluoroscopy operations, and furthermore, the existing traction reset beds usually have more parts/components and complex structures, while increasing the manufacturing cost, and further aggravate the influence of fluoroscopy in practical applications such as fluoroscopy operations. effect; in addition, although the existing traction reduction beds have many parts/components and complex structures, they have a single function and can usually only achieve one function, for example, they are only used for pelvic fracture reduction, or only for lower limb surgery traction etc., and in actual application, the existing traction reset bed can only realize the integrated lifting and lowering of the bed board, that is to say, both sides of the head and the end of the bed rise or fall at the same time. This structure usually cannot meet the actual application requirements, and cannot To achieve a good use effect, or in order to be able to achieve unilateral lifting, that is to say, the head of the bed or the end of the bed is raised or lowered unilaterally, and the bed board of the existing traction reset bed is set to two-stage or multi-stage, but this The structure further increases the number of parts/components of the existing traction reduction bed, which makes the structure of the existing traction reduction bed more complicated, the cost is further increased, and the operation is more inconvenient; in addition, the existing traction reduction bed usually cannot achieve accurate human lower limbs The traction position/angle is fine-tuned, so the existing traction reset bed has not achieved unexpected good results.
