Traction device and traction bed applying the traction device

Abstract

The invention belongs to the field of medical equipment, and discloses a traction device and a traction bed applying the traction device. The traction device includes: a traction frame main body in detachable connection with an external operation table and a rotary retracting mechanism in sliding connection with the traction frame main body; and the rotary retracting mechanism includes: a translation traction mechanism in sliding connection with the traction frame main body, the translation traction mechanism is fixedly connected to the affected limb of a patient; a lowering traction mechanismis rotationally connected to the translation traction mechanism, the lowering traction mechanism is used for supporting the traction frame main body; and a lifting-pulling mechanism is arranged on the translation traction mechanism for controlling the traction precision of the translation traction mechanism and the lowering traction mechanism. The traction bed can improve the operation efficiencyand the operation precision during operation.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a traction device and a traction bed using the traction device. Background technique [0002] At present, when minimally invasive hip surgery is performed, there are usually two ways to position the patient: one is to position the patient by manpower, such as four-character cross, raised back waist, side lying position, etc. The other is to rely on the traction bed to pull the patient to put the patient's position, and these two methods can complete minimally invasive surgery. In order to save human resources and facilitate the operation of the operator, more and more traction beds are now used to realize the placement of the patient's position. [0003] Traction beds in the prior art mainly include a traction frame fixed on the ground. The traction frame includes: a support base of the traction frame; a support wing plate fixed on the support base of the traction f...

AI Technical Summary

Problems solved by technology

[0004] 1) The traction frame of the traction bed is fixed on the ground, which makes the installation and disassembly of the traction bed relatively difficult, and can only perform surgery in a specific operating room, resulting in poor portability of the traction bed;

[0005] 2) The lower limb traction frame of the traction bed and the support base of the traction frame are usually connected by means of a ball and socket. This structure is likely to cause the limitation of the rotation angle, so that the lower limb traction angle of the traction bed is smaller;

[0006] 3) The traction bed cannot realize self-locking during the traction process. It is only locked by the locking bolt after the rotation axis is controlled by manpower. This not only increases the difficulty of the operation, but also increases the chance of patient injury after repeated traction;

[0007] 4) The traction bed does not have a parametric adjustment method during the traction process, and various body positions must be realized with the experience of the doctor, which further increases the difficulty of the operation;

[0008] 5) When the traction bed is in operation, in order to meet the purpose of seeing the patient's affected part during the operation, it is usually divided into two ways: one is to design the part of the traction bed that blocks the patient's affected part as carbon fiber, which directly increases reduce the manufacturing cost of the traction bed; the other is to place the patient in a special position, which directly increases the difficulty of the operation
