Abstract

The invention discloses an implantable pressure-controllable micro-balloon spinal nerve compression device for small animals. The implantable pressure-controllable micro-balloon spinal nerve compression device comprises a liquid containing balloon, a pressing plate, an extrusion screw, a nut sleeve and a balloon catheter which are arranged in a subcutaneous tissue. The implantable pressure-controllable micro-balloon spinal nerve compression device is characterized in that the pressing plate is arranged above the liquid containing balloon, the extrusion screw penetrates through dermal tissue from the outside of the skin to abut against the upper portion of the pressing plate, the nut sleeve is arranged in the dermal tissue and sleeves the extrusion screw, and the balloon catheter communicates with the liquid containing balloon through a liquid guide pipe to guide liquid; and a pressure gauge is further arranged at the liquid inlet portion of the balloon catheter. The device disclosed by the invention can be used for simulating spinal nerve compression injury in animal experiments, is convenient to operate and controllable in force, and can also detect pressure and improve the accuracy of the experiments.

Description

technical field [0001] The invention relates to the technical field of medical animal experiment devices, in particular to an implantable pressure-controllable microballoon small animal spinal nerve compression device. Background technique [0002] Nerves are compressed by the spine, including nerve roots and spinal cord, and radicular symptoms occur when nerve roots are compressed, such as compression of cervical nerve roots, which may cause hand numbness, compression of thoracic nerve roots can cause intercostal pain, and even because the spine is at the back, it may cause chest pain. Pain, radiating pain. If the lumbar nerve root is compressed, it can cause symptoms similar to lumbar disc herniation, which can cause radiating pain in the lower limbs. There is a component of compression of bone nerves, such as the nerve roots of the upper lumbar spine, which can manifest as pain in the front of the thigh. If the sciatic nerve is compressed, it is the lower nerve, such as...
