Abstract
The utility model belongs to the technical field of medical instrument. The purpose of the utility model is to provide a nuclear magnetic resonance pressing device of lower joints, and the nuclear magnetic resonance pressing device of lower joints has low cost. When a subject lies in a horizontal position, the nuclear magnetic resonance pressing device of lower joints can provide certain knee joint axial loads and spine axial loads to simulate the knee joint loads and the spine loads of the subject stands in a vertical position. Thereby, the kinetics changes of joint ligament and meniscus are obtained when the subject stands in a vertical position, and the states of spinal cord and intervertebral cartilage are obtained. The nuclear magnetic resonance pressing device of lower joints comprises a pair of pressurization boots (1), a support plate (2), a pulley (3), a weight (4) and a track cable (5), wherein the pulley (3) is fixedly arranged on one end of the support plate (2), the track cable (5) passes through the pulley (3), one end of the track cable (5) is connected with the pressurization boots (1), and the other end of the track cable (5) is connected with the weight (4).
Description
Technical field
This utility model belongs to medical instruments field, particularly belongs to nuclear magnetic resonance, NMR auxiliary device field.
Background technology
Since the nuclear magnetic resonance, NMR invention, nuclear magnetic resonance, NMR has become the important means that detects articular ligament, meniscus, spinal cord and intervertebral disc.But because during common nuclear magnetic resonance scanning, the experimenter is in horizontal position, hip and knee lacks axial load, can not understand articular ligament and meniscus situation when standing.And when exactly knee ligament and meniscus injury majority occur in upright motion.Same breast lumbar vertebra also lacks axial load when common nuclear magnetic resonance scanning, can not understand the situation of spinal cord and intervertebral disc when standing.And illness such as spinal canal stenosis, intervertebral disk hernia also when erect position symptom obvious.Therefore understand knee joint and lumbar vertebra under the normal axial load condition, articular ligament, the change of meniscus kinetics and spinal cord, intervertebral disc state are most important.
In recent years, though the world is to have designed orthostatism nuclear magnetic resonance scanning system to detect data under the knee joint load condition, but because it costs an arm and a leg, and its imaging is clear not as conventional NMR system imaging, still there is not under the knee joint load condition relevant report of front and back ligamentaum cruciatum and meniscal stretching displacement situation in the world.
Summary of the invention
The purpose of this utility model is to provide a kind of low price, certain knee joint and spinal column axial load can be provided when experimenter's horizontal position, joint when simulating erect position and spinal load, thereby the nuclear magnetic resonance, NMR hypozygal pressue device of articular ligament, the change of meniscus kinetics and spinal cord, intervertebral disc state when obtaining erect position.
The purpose of this utility model is achieved in that nuclear magnetic resonance, NMR hypozygal pressue device, comprises adding pressure shoes [1] gripper shoe [2], pulley [3], counterweight carrier [4], track cable [5]; Wherein, pulley [3] is packed in an end of gripper shoe [2]; Track cable [5] is by pulley [3], and the one end connects and adds pressure shoes [1], and the other end connects weight [4].
Described nuclear magnetic resonance, NMR hypozygal pressue device all adopts the nonmetallic materials manufacturing.
Because when the normal human stood, bilateral knee was closed and is saved the axial load of bearing experimenter's 80% body weight.When adjustment weight weight reaches 40% body weight, axial load in the time of then can producing the simulation erect position in the unilateral knee joint.When needs provide the lumbar vertebra axial load, then fixing band is fixed on chest and shoulder, biped is all put on and is added pressure shoes.Track cable adds pressure shoes and fixes with two respectively, converges then and links to each other with weight together.Because when the normal human stood, lumbar vertebra was born the axial load of experimenter's 50% body weight approximately.When adjusting weight weight and reaching 50% body weight, then can be when lumbar vertebra produces the simulation erect position axial load.
The beneficial effects of the utility model are: certain knee joint and spinal column axial load can be provided when experimenter's horizontal position, joint when simulating erect position and spinal load, thereby articular ligament, the change of meniscus kinetics and spinal cord, intervertebral disc state when obtaining erect position.
Description of drawings
Fig. 1 is this utility model structural representation.Wherein, 1, add pressure shoes, 2, gripper shoe, 3, pulley, 4 counterweight carriers, 5 track cables.
The specific embodiment
Referring to accompanying drawing 1, nuclear magnetic resonance, NMR hypozygal pressue device comprises adding pressure shoes [1] gripper shoe [2], pulley [3], counterweight carrier [4], track cable [5]; Wherein, pulley [3] is packed in an end of gripper shoe [2]; Track cable [5] is by pulley [3], and the one end connects and adds pressure shoes [1], and the other end connects weight [4].
Described nuclear magnetic resonance, NMR hypozygal pressue device all adopts the nonmetallic materials manufacturing.
During use, the experimenter is flat to crouch on gripper shoe, and with fixing band chest and buttocks and gripper shoe is fixed, and monopodia is put on and added pressure shoes.The counterweight carrier then adds pressure shoes by the pulley tractive, and knee joint is produced axial load.Thereby adjust the size of axial load by the weight of regulating balancing weight in the counterweight carrier.
