Technical Field

The invention relates to a pressure detection device for X-ray films, in particular to a pressure detection device for X-ray films, which is used for fixing a part to be inspected, applying certain pressure to the inspected part and inspecting the joint or ligament tear through the X-ray films.

Background

Generally, when taking an X-ray film, it is important to confirm the posture of a patient or whether a specific part thereof is accurately located in the imaging field and then to perform X-ray imaging in order to obtain an X-ray image at an accurate position. The posture of the patient referred to herein may include a motion of moving the body or support of the patient and also include various motions that enable the position of the patient to be adjusted within the photographing range.

Bone or ligament tears are related to the force, velocity, and direction applied to the bone or ligament. In order to inspect the torn portion of the ligament, a pressure inspection method is widely used, in which a pressure is applied to the torn portion for a predetermined time and then an abnormal condition is determined according to the degree of deformation of the torn portion.

The pressure inspection method is an inspection method for judging the torn ligament by applying a certain pressure to the inspected part and grasping the ligament deformation degree through an X-ray film as described above.

In the conventional pressure examination method, since a doctor, a nurse, or a caregiver applies pressure to an examination site of a patient to be examined by grasping it with a hand during the examination, the force of applying pressure to the examination site varies from person to person, and the examination site is not yet combined, causing pain to the patient to be examined, and the examination cannot be accurately performed.

The medial ligament (deltoidlication) has a recoil force against eversion of the ankle and consists of the tibial navicula (tibioonasal) and the tibial ligament (tibiocanasal ligament). The tibiofibular external ligament (tibiofibular ligament) is responsible for plantar flexion (plantar flexion).

Next, a method of examining a human body using the examination apparatus will be described with reference to a patient-selectable shape and structure capable of determining a Magnetic Resonance Imaging (MRI) diagnosis according to an embodiment of the present invention.

Referring to fig. 16 and 17 (Knee Varus Stress test, Knee Stress Valgus (MCL), and fig. 18 and 19 (Knee Varus Stress test, LCL)), a pressing part 400 is provided in the middle of the two first fixing members 250, a protective member 450, i.e., a front Pad (quartz Pad), is placed above the joint (articular space), the Knee is bent at least 15daN (not more than 30 °) for Routine (Routine) examination, and the applied Pressure (Pressure) is about 15daN at the time of Routine examination.

C. Diagnostic Instructions (Instructions for diagnostics)

Measuring the width of the Articular space (Articular space)

More than-15 mm, clearly visible

More than-10 mm, necessary for comparison with X-ray (X-ray)

Above-3 mm, pathological lesions are present

Examination of the anterior cruciate ligament (interpretation of the organ crystalline ligament, ACL)

A. Stress before Knee (Knee Stress Lachman Anderior)

Referring to fig. 20 and 21, the patient bends the knee by 15 ° to 20 ° while the lateral side of one knee joint (joint) is detected to be close to the pressure device and the two side condyles (continuations) are overlapped (true laterals). The femoral joint (femur continulus) and the front of the ankle part were fixed by an instrument, and a pressure pad was used to apply a pressure of about 15kp to a 7cm part from the knee fossa (posterior to tibial tubercle level, posterior to knee). In the case of a simple muscle injury, the applied pressure is about 20 kp. Measurements were performed with the tibial plateau (media) and lateral parallel to each other) around the posterior aspect and near the femoral joint (femurodynamic).

Knee joint Stress (Knee Stress Lachman Posterion, FIG. 21)

Referring to fig. 22 and 23, the patient bends the knee by 15 ° to 20 ° while the lateral side of the knee joint is detected to be in close contact with the pressure device (stress device) and the two side condyles (continuations) are overlapped (true laterals). The femoral joint (femur continulus) and the rear of the ankle part were fixed by an instrument, and a pressure pad (pressure pad) was used to apply a pressure of about 15kp to a 7cm part from the popliteal fossa (behind the tibial tubercle level, the rear of the knee). In the case of a simple muscle injury, the applied pressure is about 20 kp. The tibial plateau (medial) and lateral (lateral) posterior circumference (rear) and the femoral joint (femur dylars) were measured after approaching the tibial plateau (Tibia plateau, in a state where medial and lateral are parallel) as close as possible.

B. Diagnostic Instructions (Instructions for diagnostics)

Referring to fig. 24 and 25, the patient is allowed to bend his/her knee 90 ° and await examination, with the pressure device positioned exactly above the Patella (Patella). When the basic diagnosis is performed, the scale of the pressure equipment is adjusted to about 15Kp for use. Place sandbags under the ankles, with the tibia (tibia) parallel to the surface. (use of true lateral (true lateral) to avoid double imaging of femoral condyles)

B. Diagnostic Instructions (Instructions for diagnostics)

This is a diagnosis of vertical displacement of the tibia (tibia head) by X-ray imaging, and if it exceeds 3mm, it is considered abnormal. If it is about 2mm, it is clinically regarded as a tear (rupture).

5) Examination of the posterior cruciate ligament (90 degrees) (Special Access administration of the spatial relationship (90 degree position))

The protection member 450 of the pressing part 400, i.e., the pressure pad, is placed at a position 2cm below the tibia (tibia). Confirm whether the pressure of the general examination is at 15 daN. A small sandbag is padded under the ankle to keep the tibia (tibia) in balance with the table top.
