prosthetic socket 

prosthetis socket    Receiver cavity fabrication technology   Critical in prosthetics   The prosthetic socket is an important medium connecting the residual limb and the prosthetic component. It can accommodate the residual limb and play the role of carrying the body weight, transmitting the force and controlling the prosthesis.   Prosthetic sockets must conform to anatomy and biomechanics. Prosthetic manufacturers require comfort in use and are responsible for power transmission and motion transmission functions. The design and production of sockets are a very critical part of prosthetic installation.   Amputee patients who have worn prosthetics know that the residual limb is affected by various unavoidable forces such as rotational force, frictional force, torsion force, and impact force in the receiving cavity. In addition, the residual limb has many unforced bony prominences, irregular shapes, sensitive skin and other factors, and some even serious deformation affects the alignment of the prosthesis, which should be carefully considered and solved in the design and manufacture of the prosthetic socket.   The current prosthetic sockets mostly use full-contact sockets. Compared with the traditional insertion type, there has been a significant improvement in technology. For example, the thigh sockets have changed from plug-in sockets to quadrilateral bone load-bearing sockets to bone inclusion, bone Supporting and containing the receiving cavity, Suzhou prosthetic manufacturers, especially the application of lining materials such as silicone, finger prosthetic manufacturers, have solved the ineffective forces inside the receiving cavity, and improved the force transmission performance and comfort of the receiving cavity.   The prosthesis is not a commodity but a product. Please choose to install it in an experienced rehabilitation service institution to ensure the quality of the product and the quality of installation and production, as well as to ensure follow-up services.   SHIJIAZHUANG AOSUO O&P

Design of Disables pneumatic knee

Design of Disables pneumatic knee     The overall structure of the pneumatic knee joint: the pneumatic knee joint is composed of a four-bar linkage mechanism and a damping cylinder  According to the requirement that the rotation range of the knee joint of the human body is less than 180°, the four-bar linkage mechanism can adopt a double rocker structure. To ensure the stability of the simulated human body when it is standing, the rotation direction of the joystick should be limited. It can only start from the limit point, rotate clockwise and return to the limit point counterclockwise. The limit point is exactly the position where the person is standing. Four The connecting rod mechanism is low-amplitude movement, with low wear and tear, and can meet the requirements of long-term use. The connecting rod mechanism is simple, small in size, light in weight, and suitable for the requirements of prosthetics. The design of 0.6～1MPa can meet the needs of 60～80kg weight. The damper can be designed on the cylinder body or on the piston.   shijiazhuang aosuo o&p

Scope of application of fixers（三）

Scope of application of fixers（三）   The knee joint is structured as complex and therefore very vulnerable to damage. As the most stressed joint in the human body, it bears almost the weight of the entire body. Combined medial and lateral ligaments and anterior and posterior cruciate ligaments maintain the stability and motility of the knee. Two cartilage discs and meniscus act a buffer against pressure. Excessive stretching of the knee joint or lower limb fixation during exercise and excessive distortion of the joint can often lead to tears of the anterior cruciate ligament. The posterior cruciate ligament rupture is often due to a direct collision at the front of the lower limb or an accidental overextension of the knee joint. First, the doctor will ask several questions about the patient's complaints and accompanying symptoms. The more important ones include the duration of the knee pain, the specific location of the pain, and the general timing of its occurrence. To better clarify the cause of knee pain, previous diseases, existing diseases, or previous accidents are also associated with the diagnosis The depth test for the knee will be required after multiple exercise tests. The doctor can decide the location and severity of the joint damage based on the main complaint (knee swelling, joint fluid extravasation, range of limited motion). Patients with knee pain may also need additional tests based on clinical signs to make a clear diagnosis. These tests include x-ray, ultrasound scan, MRT, knee arthroscopy, or joint suction. Whether the fixer is suitable and whether you can make the most of the function of the product depends on a variety of factors, among which, your physical condition, health condition and detailed physical examination are very critical. Also, a doctor or technician will help you determine which anchor is right for you.  SHIJIAZHUANG AOSUO O&P

Scope of application of fixers（二）

Scope of application of fixers（二） Back pain is caused by the body (organs) and / or psychological factors, as well as the wrong posture and incorrect weight bearing. Possible causes include: Similar injuries such as vertebral rupture, vertebral dislocation, or nerve root tears  inflammation Clinical manifestations of wear (degeneration) include osteoarthritis, osteoporosis, spondylitis ankylopoietica, disc prolapse, spinal instability, muscle imbalance, or unequal lower limb length, and static position disorders in the body.The backache can be divided into radiculopathy and pseudoradiculalgia. In patients with nerve root pain, they receive stimulation- -such as back pain due to disc prolapse, while in patients with pseudonerve root pain, backache is caused by changes in the spinal small joints. Other identification features include  Low back pain: a sudden onset of back pain Chronic back pain: Back pain occurring for more than 3 months Pain in the lower back and radiating pain in the lower limbs Loss of control over the lower limb function  vesical dysfunction                                                                             SHIJIAHZUANG AOSUO O&P

Scope of application of fixers（一）

Scope of application of fixers（一）   The upper part of the ankle joint may be caused by congenital or acquired ligament relaxation, accompanied with or without other abnormal joint stable structures (such as joint capsule, joint cartilage, meniscus, muscle structure).In an ankle sprain with or without external force, the ankle ligament may be excessively elongated or even rupture. Ankle instability is usually defined by the number of joint ligament structures accumulated. The more joint ligament damage, the worse the ankle structural stability Whether the fixer is suitable for you and whether you can make the most of the function of the product depends on a variety of factors, among which, your physical condition, health condition and detailed physical examination are very critical. Also, a doctor or technician will help you determine which anchor is right for you. The joint instability begins to appear as gait instability, possibly accompanied by pain and friction sounds. In acute joint instability, such as joint rupture, swelling and skin discoloration change at the injured site. Chronic joint instability and osteoarthritis, such as increased arthrodial cartilage wear at the joint, are often a consequence of long-term injury, especially when acute joint injury is not adequately treated.   For ankle instability, preliminary tests such as the talus tilt test, followed by diagnostic imaging tests such as MRI, x-ray, or ultrasound, are generally required.   SHIJIAZHUANG AOSUO O&P

What to do if the stumps sweat and stink in summer?

What to do if the stumps sweat and stink in summer?   The hot summer is a difficult season for prosthetic patients, and the residual limbs will have various problems due to the weather. How to solve the problem of various complications caused by sweating of residual limbs in summer?   1. When it is convenient to go to work, you can slightly remove the prosthesis for more ventilation, and try to take off the prosthesis when you get home. Try not to go out and stay indoors.   2. It is recommended to wash the residual limb and receiving cavity with light saline every day, and pay attention to drying.   3. It can be solved by cooling or frequent disinfection, and the possibility of infection is very small. It is recommended to clean the sweaty part of the amputation frequently, and it is best to disinfect it with alcohol! Or local application of alcohol and a towel with alcohol will have a good cooling effect.   4. You can take vitamin C. If the itching is severe, you can use calamine lotion! Also, change and wash the stockings of the residual limbs.   SHIJIAZHUANG AOSUO O&P
