Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a length-adjustable elbow valgus degree detection device. Background Art

[0002] The method of measuring elbow valgus involves the following steps: First, ask the subject to straighten both upper limbs to ensure that the elbow joints are fully extended. Next, place both hands in front of the chest with the palms facing up and parallel to each other, and maintain this position. Then, use a large triangle ruler to draw a straight line from the biceps above the elbow joint down the arm. The angle formed by this line and the forearm below the elbow joint is the angle of elbow valgus. In clinical practice, if this angle exceeds 20 degrees, it is usually considered to be a case of elbow valgus.

[0003] The prior art CN219070309U discloses an elbow joint inclination measuring device for orthopedic surgery, and the technical solution discloses "including two major parts: a bracket and a forearm intramedullary rotation stress mechanism. Among them, the bracket is provided with an upper arm loading platform, a forearm sliding cross bar, two first pressure pulleys, a forearm intramedullary rotation stress mechanism and two second pressure pulleys. The outer section of the intramedullary nail of the forearm intramedullary rotation stress mechanism extends out of the distal ulna of the forearm and is connected to a torque tester to provide a forearm rotation stress load. The first pressure pulley provides an inversion and valgus pressure load for the forearm, and the second pressure pulley provides an axial pressure load for the elbow joint. Advantages of the utility model: the flexion and extension angle of the elbow joint can be freely adjusted, and stress in three directions can be provided to the elbow joint at the same time, namely, inversion and valgus stress, forearm rotation stress and elbow joint axial stress. In conjunction with the loading system, different stress conditions of the elbow joint can be simulated at any angle, which basically meets the variables required in the elbow joint biomechanics experiment and is suitable for large-scale promotion."

[0004] Although the prior art has disclosed an elbow joint inclination measuring device for orthopedic surgery, there are still some shortcomings. Specifically, during the rotation of the forearm, the inclination measuring device lacks a fixing mechanism, and the forearm may be offset during the rotation, and the inclination angle between the upper arm and the forearm changes, resulting in errors in the measurement results. In addition, before and after using the inclinometer, some instruments need to be cleaned and disinfected to achieve sterility of the detection equipment, and the prior art is not convenient for disassembly. Therefore, although the prior art has provided an elbow joint inclination measuring device for orthopedic surgery, it still has some areas that need to be improved in practical applications to ensure its measurement accuracy and safety of use. Summary of the invention

[0005] The purpose of the present invention is to provide a length-adjustable elbow valgus detection device to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a length-adjustable elbow valgus detection device, characterized in that: the device includes a base and a sliding mechanism, a hydraulic system is installed inside the base, one end of the piston rod in the hydraulic system is connected to a support plate, the support plate slides within a certain range through a slide rail, an arc-shaped baffle is connected to the support plate, a pressure sensor is installed on the inner side of the arc-shaped baffle, a medical nursing pad is installed on the inner side of the arc-shaped baffle, a photoelectric angle measuring instrument is installed on the base, the photoelectric angle measuring instrument is connected to an electronic display screen, the photoelectric angle measuring instrument is responsible for measuring the angle between the telescopic plate and the pad, the electronic display screen can display the degree of the valgus angle, one end of the base is connected to a telescopic plate, the telescopic rod can adjust the length, the telescopic rod is connected to a rotating ring, the rotating ring is connected to a pad, and one end of the pad is connected to a cuff.

[0007] The hydraulic system includes a hydraulic pump, a hydraulic cylinder, an oil pipe, an oil inlet, a valve switch, a piston, a piston rod and a hydraulic spring. It is installed at the bottom of the base and is responsible for providing power. The hydraulic pump is connected to the hydraulic cylinder through an oil pipe. A valve switch is also installed on the oil pipe to control the flow of hydraulic oil. An oil inlet is provided on the cylinder barrel, and the hydraulic oil enters the hydraulic cylinder through the oil inlet. A piston is also installed inside the hydraulic cylinder. The piston reciprocates under the action of the hydraulic oil. The piston is connected to the piston rod, and a hydraulic spring is sleeved on the piston rod. The function of the hydraulic spring is to provide rebound force to ensure that the piston rod can return to its initial position.

[0008] The sliding mechanism includes a slide rail, a support plate and a slider. The slide rail is installed on the upper surface of the base, and the slider is arranged inside the slide rail. The slide rail provides a stable guide rail system for the sliding mechanism. The support plate is closely connected with the piston rod to ensure that the piston rod can stably transmit force during movement. The connection between the support plate and the slider further enhances the stability of the overall structure. The slider moves smoothly on the slide rail to achieve the required mechanical movement. This design not only ensures the flexibility of the sliding mechanism, but also improves its durability and reliability.

[0009] The fixing mechanism includes an arc-shaped baffle, a medical care pad and a limit plate. The arc-shaped baffle is installed on the inner side of the support plate. A pressure sensor is provided on the inner side of the arc-shaped baffle. A groove is designed on the inner side of the arc-shaped baffle. The function of the groove is to accommodate and fix the medical care pad to ensure that it can be stably maintained in the appropriate position during use. A limit plate is set on one side of the arc-shaped baffle. The limit plate is used to limit and control the movement range of the medical care pad in the groove, thereby ensuring the stability and safety of the overall structure.

[0010] The rotating mechanism includes a telescopic plate, a rotating ring, a pad and a cuff. One end of the telescopic plate is connected to the rotating ring through a connecting piece, and one end of the pad is also connected to the rotating ring through a connecting piece, so that the pad can form a rotating connection with the telescopic plate, so that the pad can rotate freely within a certain range. A dial is provided on the surface of the rotating ring, and the degree of the elbow valgus angle can be directly read out for comparison with the degree on the electronic display screen, thereby enhancing the accuracy of the entire device. A rubber pad is also laid on the surface of the pad to play a buffering role. A cuff is also installed at one end of the pad, and the cuff can be fixed on the user's forearm.

[0011] The photoelectric angle measuring instrument is installed at the upper position of the base. On the right side of the photoelectric angle measuring instrument, an electronic display screen is set to display the detection results and related information in real time. The electronic display screen and the photoelectric angle measuring instrument are connected to each other through a circuit system.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. A set of slide rails are installed at the upper end of the base. These slide rails provide necessary guidance and support for the movement of the slider and the support plate. The bottom of the support plate is connected to a number of sliders, which can slide back and forth inside the slide rails, so that the entire support plate can move within a certain range. The inner edge of the support plate is closely connected to an arc-shaped baffle. A pressure sensor is installed on the inner side of the arc-shaped baffle. A groove is designed on the inner edge of the arc-shaped baffle to firmly accommodate and fix the medical care pad. The medical care pad is placed in the groove. Its main function is to provide comfortable support and protection for the upper arm. Through the coordinated work of the above-mentioned mechanisms, the upper arm can be effectively fixed in an appropriate position, thereby providing a stable and comfortable nursing environment for patients. This design not only improves the efficiency of nursing, but also greatly enhances the comfort and satisfaction of patients.

[0013] 2. In the design of the hydraulic system, the top of the piston rod and the support plate are tightly connected together through welding process, thus ensuring the stability and reliability of the whole system. When the upper arm is placed in the fixing mechanism, the hydraulic system starts to start and run, the valve switch on the oil pipeline is opened, and the hydraulic pump starts to work, delivering hydraulic oil into the oil pipeline. The hydraulic oil enters the cylinder from the oil inlet, pushing the piston forward, and then driving the piston rod to extend outward. The movement of the piston rod drives the support plate to move. In order to ensure that the upper arm can be accurately positioned in the appropriate position, a pressure sensor is set on the inner side of the arc baffle. This pressure sensor can sense the pressure exerted by the medical nursing pad on the upper arm. When the nursing pad squeezes the upper arm appropriately, the pressure sensor will receive the corresponding signal and immediately transmit these signals to the control system. After receiving the signal, the control system will instruct the valve switch to close, thereby stopping the delivery of hydraulic oil. The arc baffle will be fixed in a suitable position to ensure that the upper arm is stably maintained in the appropriate position. The piston rod is sleeved with a hydraulic spring. The function of the hydraulic spring is to provide rebound force to ensure that the piston rod can return to its initial position.

[0014] 3. When the equipment needs to be disinfected and cleaned, first open the limit plate on the upper side of the arc-shaped baffle. After doing so, you can easily take out the medical care pad placed in it, then put the new medical care pad into the corresponding position, and then close the limit plate to ensure that the new medical care pad is firmly fixed in the appropriate position. The taken out medical care pad can be put into use again after proper disinfection and cleaning procedures, thereby realizing the recycling of resources. BRIEF DESCRIPTION OF THE DRAWINGS
