[0025] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0026] The utility model provides an automatic traction device for orthopedic surgery, comprising:

[0027] The traction host is arranged on the operating table, and the output end of the traction host is connected to one end of the traction shaft;

[0028] A traction wheel is provided at the other end of the traction shaft, and a traction rope is wound around the traction wheel, and the traction rope is used to connect with the traction bow or traction needle;

[0029] Handheld controller, connected to the traction host control.

[0030] Specifically, the traction device includes a traction main unit, a traction shaft, a traction wheel and a handheld controller. The device is fixed to the operating table through the traction main unit, and the rotation of the traction wheel is controlled by the handheld controller. In this way, the traction rope can drive the traction bow to traction and correct the patient's part. The doctor can complete the operation alone, and no human traction is required during the correction process. It is only necessary to control the output traction force of the traction main unit. The operation is simple and labor-saving.

[0031] Optionally, the traction host includes a clamping mechanism and a power mechanism, one end of the clamping mechanism is connected to the operating bed, the other end of the clamping mechanism is connected to the main housing, and the power mechanism is arranged in the main housing.

[0032] Specifically, the traction main unit is connected to the operating table through a clamping mechanism, and the traction shaft is driven by a power mechanism to output traction force. The traction main unit can be decomposed into two independent parts as needed, which is convenient for future maintenance.

[0033] Optionally, the clamping mechanism includes a U-shaped clamping groove and a bed clamp, the bed clamp is slidably arranged in the clamping groove, and a knob is provided through one side wall of the clamping groove, and one end of the knob abuts against the bed clamp.

[0034] Specifically, the clamping mechanism includes a clamping groove arranged in the horizontal direction, which is wrapped around the bed board of the operating bed. The opening size of the clamping groove is larger than the thickness of most bed boards. Then, by turning the knob, the bed clamp is moved closer to the groove wall on the other side of the clamping groove, and the bed board is clamped and fixed by the bed clamp and the groove wall on the other side, so that the traction device can be fixed.

[0035] Optionally, the power mechanism includes a motor and a reducer, the output end of the motor is connected to the reducer, and the reducer is connected to the traction shaft through an output shaft.

[0036] Optionally, the reducer is a worm gear reducer.

[0037] Specifically, the power mechanism drives the traction shaft to rotate through the motor, and a reducer is set during the power transmission process to achieve speed reduction and torque increase, thereby improving the traction effect of the traction equipment; a worm gear reducer is used as the reducer, so that through its own self-locking function, it can ensure that the equipment can provide stable and continuous traction without reversal.

[0038] Optionally, a torque sensor and a coupling are connected in sequence between the reducer and the output shaft, and the handheld controller is connected to the torque sensor and the coupling.

[0039] Specifically, when operating the traction equipment, the motor output power is monitored by a torque sensor and displayed on the controller screen to avoid situations where the traction force is too small or too large. When the traction force is too large, the coupling can perform overload protection to prevent the patient from being injured again.

[0040] Optionally, the traction shaft includes a lower traction shaft and an upper traction shaft, the lower end of the lower traction shaft is connected to the traction main body, the upper traction shaft is inserted into the lower traction shaft, and the upper end of the upper traction shaft is connected to the traction wheel.

[0041] Optionally, the lower traction shaft and the upper traction shaft are detachably connected.

[0042] Specifically, the upper traction shaft and the lower traction shaft are extension shafts of the traction device, which are disassembled for easy disinfection; by adjusting the height of the traction shaft, the traction position can be made higher than the bed and higher than the patient being traction, which is convenient for surgical operation and observation.

[0043] Optionally, the handheld controller is provided with a start / stop switch, a speed knob, a traction knob and a threshold knob.

[0044] Specifically, the handheld controller is connected to the traction host through an aviation plug line. The handheld controller can control the start and stop of the equipment, set parameters such as traction speed, traction force, traction threshold, etc., and can observe the numerical changes of these parameters in real time, and adjust the traction force at any time based on the surgical effect. The traction speed can also be adjusted, which can save traction time; when the handheld controller is not in use, it can be placed in the slot of the traction host and taken out when used.
