Description

Stress stimulation device for lower limb fracture

Technical Field

The utility model relates to a medical instrument, in particular to a stress stimulation device for healing after lower limb fracture operation.

Background

Proper stress stimulation can promote bone healing, and most fracture patients are easy to cause delayed healing or non-healing of fracture due to lack of proper stress stimulation of postoperative patients clinically. During the bedridden period of the fracture patient, doctors generally order the accompanying staff to hammer the soles of the patient with fists every day, so that the fracture part is stressed and stimulated to accelerate fracture healing. This behavior is relatively boring, and hammering the foot is not acceptable to everyone, and compares the patience of the caretaker. To solve the above-mentioned problems, patent application document 202210073697.X discloses a "traction device for promoting healing after long bone fracture operation", which can perform stress stimulation on fracture patients. However, the device is heavy, takes time for disassembly and assembly, and is inconvenient. For small foot fractures of lower limbs, the fracture site needs to be wrapped with thick plaster, and the device is not very suitable for use.

Disclosure of Invention

The technical problems to be solved by the utility model are as follows: in order to solve the problems, a stress stimulation device for lower limb fracture is provided.

The technical scheme of the utility model is as follows: the utility model provides a low limbs fracture stress nature stimulation device, including electronic hammering device, the base, and support, electronic hammering device includes the tup, the hammer handle, cam and driving motor, the tup sets up the front end at the hammer handle, the hammer handle is articulated in the position that is close to the rear end and the one end of a branch, and be equipped with the spring effect on the hammer handle in articulated department, be used for with the tup bullet to patient's foot, the other end of branch is connected on the support, the cam rotationally sets up in the one end of support and is rotatory by driving motor drive, the rim of cam contacts the cooperation with the rear end of hammer handle, the cam rotates and drives the tup swing, the other end of support is connected on the base.

The utility model has the technical effects that: has the advantages of simple structure, low cost and convenient use, and is very suitable for the stress stimulation of lower limb fracture. The vertical height of the hammer head position can be adjusted by adjusting the inclination angle of the bracket. The hammer head can be buffered through a spring, the strength is moderate, and the hammering strength can be adjusted through the movement of the distance. When in use, the foot-rest device is directly placed under the foot without preparing in advance, and can work after the power supply is turned on. When not in use, the product can be directly taken away.

Detailed Description

As shown in fig. 1 to 4, the lower limb fracture stress stimulation device comprises an electric hammering device, a base 1 and a support 2, wherein the electric hammering device comprises a hammer head 3, a hammer handle 4, a cam 5 and a driving motor 6, the hammer head 3 is arranged at the front end of the hammer handle 4, the hammer handle 4 is hinged with one end of a supporting rod 7 at a position close to the rear end, a spring is arranged at the hinged position and acts on the hammer handle 4 and is used for bouncing the hammer head 3 towards the foot of a patient, the other end of the supporting rod 7 is connected to the support 2, the cam 5 is rotatably arranged at one end of the support 2 and is driven to rotate by the driving motor 6, the rim of the cam 5 is in contact with the rear end of the hammer handle 4, and the cam 5 rotates to drive the hammer head 3 to swing, and the other end of the support 2 is connected to the base 1. The driving motor can be arranged at the hinge position above, and the cam is directly driven to rotate through the speed reducer. The motor is arranged above the support, so that the volume above the motor can be increased, the load of the support is increased, and the overall power is small, so that the influence is small. The torsion spring is arranged at the hinge shaft of the hammer handle and the supporting rod, or the tension spring is arranged between the hammer handle and the supporting rod to drive the tail end of the hammer handle to be close to the cam, so that displacement is generated when the tail end of the hammer handle suddenly falls down at the jump position of the cam, and the action of striking the foot of a patient is obtained.

The hammer head 3 is connected with the hammer handle 4 through a buffer spring 8.

The hammerhead 3 is a rubber ball. The cushion spring and the rubber ball can improve the touch sense and reduce discomfort.

The hammer handle 4 is connected with the cam 5 through a roller 9.

The support rod 7 and the cam 5 are coaxially hinged to the support 2, and a locking nut is arranged on the hinge shaft and used for clamping the support rod 7 on the support 2. The coaxial arrangement can not influence the swing amplitude of the hammer head when the angle of the supporting rod is adjusted.

The support 2 is hinged with the base 1, and the hinge shaft is provided with a locking nut for locking the intersection angle of the support and the base.

The output shaft of the driving motor 6 and the support 2 are arranged coaxially with the hinge shaft of the base 1, and the driving motor 6 drives the cam 5 to rotate through a belt wheel and a transmission belt. When the angle of the bracket is adjusted, the transmission is not affected.
