Abstract
Description
Technical field:
[0001] The invention relates to a carbon fiber traction frame suitable for orthopedic surgeries of femoral heads and lower limbs. Background technology:
[0002] The orthopedic operating table is an essential tool for doctors during orthopedic surgery. With the development of society, there are more and more types of orthopedic operating tables. The existing head mechanisms of orthopedic operating tables can only be turned at different angles. Due to the long operation time, the patient's head will suffer secondary injuries. In the past, the waist bridge of orthopedic operating tables was mostly manually lifted and lifted by a dual-control hydraulic system. The manually lifted waist bridge is more troublesome to use. The waist bridge of the dual-control hydraulic system has a large pressure difference when in use, and the oil circuit working resistance is particularly large, the stability is poor, the waist bridge is easy to shake, and the waist bridge will vibrate when it is lifted and lowered. The working pressure cannot be adjusted at will according to the patient's condition and weight. and working status. The height of the ordinary orthopedic operating table needs to be raised according to the patient's condition and the body position required by the doctor. Since the height of the operating table is relatively high, the covers cannot be guaranteed to be stable and synchronous during the descent, so they often get stuck. When the general operating table is used interchangeably, it is often difficult to disassemble, which causes a lot of trouble for the doctor. Therefore, there is a need for a carbon fiber traction frame for femoral head and lower limb orthopedic surgery that has good stability, is easy to disassemble and repair, can be quickly disassembled and assembled to different positions to meet the doctor's usage requirements, realizes multiple body positions and angles, and assists doctors in performing surgery.

[0034] 14. The working principle of the hydraulic system of the present invention is: under the action of the oil pump, the pressure oil enters the pressure system, when the solenoid valve on the left side of the lifting reversing valve is energized, the valve core of the solenoid reversing valve moves, at this time, oil enters the lower part of the lifting cylinder, and the lifting system rises, when the solenoid valve on the right side of the lifting reversing valve is energized, the valve core of the solenoid reversing valve moves, at this time, oil enters the upper part of the lifting cylinder, and the lifting system rises and falls. Since vacuum phenomenon is likely to occur when the lifting cylinder descends, the present invention arranges a pressure regulating valve in the lifting cylinder mechanism to ensure that the lifting cylinder mechanism descends smoothly.

[0081] Embodiment 8:
[0082] A method for installing and using the carbon fiber traction frame suitable for femoral head and lower limb orthopedic surgery according to embodiments 1-7, the method comprising the following steps:
[0083] Except for the hips which cannot be freely interchanged, the other parts can be disassembled and interchanged at will. Through a special locking mechanism, they can be quickly disassembled. The back and head can be disassembled at will, and they can also be assembled in the opposite direction. In particular, the leg panels can be freely disassembled. Since the original leg panels are two pieces, positioning is required for installation. In the past, it was impossible for us to interchange the head and leg panels. This time, we use such a double insertion mechanism to ensure both positioning and locking mechanism. It is such a double locking mechanism that ensures the free interchange of the head, leg panels and traction frame.
[0084] The functions of the various components of the carbon fiber traction frame suitable for femoral head and lower limb orthopedic surgery are as follows:
[0085] Quick-release mechanism: The matching relationship is good. When there is a little error between them, the square tube can automatically deform and adjust. Because the circumference of the square tube is greater than the equilateral diameter axis, when the equilateral diameter axis is inserted, there is an error, and the square tube can automatically deform and adjust.
[0086] Head structure: The folded angle of the head plate allows the patient's head to rise to a certain height during surgery, which can increase the patient's comfort during the operation.
[0087] Back mechanism: A hydraulic circuit is added to the single control system to ensure the normal function of the pressure reducing valve.
[0088] Hip mechanism: The meshing noise of the helical gear and the helical rack is low, the controllability is good, the car can be parked at any position, and the direction can be adjusted at any time.
[0089] Traction frame mechanism: To solve the problems of lateral translation of the traction frame, doctors have increased the angles of the traction frame and increased the degree of freedom when performing surgery on patients.
[0090] Lifting mechanism: The mechanism is a parallel four-bar mechanism. First, the covers will not get stuck when lifting. Secondly, stability can be guaranteed during the lifting process. Finally, the covers are synchronized during the lifting process.
