Nerve conduit with guiding function for repairing peripheral nerve injury

Abstract

The invention discloses a nerve conduit with a guiding function for peripheral nerve injury repair, and particularly relates to the technical field of peripheral nerve injury repair, the nerve conduit comprises a mounting disc, a reducing assembly is mounted on the upper surface of the mounting disc, and the reducing assembly comprises a power shaft and a rotating shaft; and the outer walls of the power shaft and the rotating shaft are fixedly sleeved with a small belt wheel and a large belt wheel correspondingly. Through the arrangement of the reducing assembly, the inner diameter of the catheter can be changed according to the growth condition of nerve cells around a patient, operation is easy, adaptability is high, the growth efficiency of the nerve cells around the patient is improved, through the arrangement of the dredging assembly, flowing of medicine can be limited, and the contact time of the medicine and the cells is long enough; coagulated medicine can be pulverized, pipeline blockage is prevented, transmission of electromagnetic signals and direct irradiation of light of the LED irradiator to peripheral nerve cells are achieved, and the growth quality and the growth effect of the peripheral nerve cells are guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of repairing peripheral nerve injuries, and in particular to a nerve guide with a guiding function for repairing peripheral nerve injuries. Background technique [0002] Peripheral nerve injury refers to a clinical condition in which the peripheral nerve trunk or its branches are accidentally injured by external direct or indirect trauma, resulting in motor, sensory and autonomic dysfunction of the trunk and limbs. If effective treatment is not carried out as soon as possible, it will affect the structural development of the affected limbs, thereby affecting life, study and work, and also have a certain impact on psychological development. Peripheral nerve injury mainly manifests as motor dysfunction, sensory dysfunction, and neurotrophic changes. Most of them require surgical treatment. Some patients can be cured, but a small number of patients are permanently disabled. Peripheral...

Problems solved by technology

[0005] To this end, the embodiment of the present invention provides a nerve catheter with a guiding function for peripheral nerve injury repair. Through the setting of the variable diameter component, the inner diameter of the catheter can be changed according to the growth of the patient's peripheral nerve cells, and the operation is simple. High adaptability increases the growth efficiency of the patient's peripheral nerve cells. Through the setting of the dredging component, the flow of drugs can be restricted, so that the contact time with the cells is long enough to crush the coagulated drugs and prevent the pipeline from clogging. The transmission of the electromagnetic signal and the light of the LED irradiator are directed to the peripheral nerve cells, which ensures the growth quality and growth effect of the peripheral nerve cells, and solves the problem that the inner diameter of the nerve guide is difficult to follow according to the growth of the patient's peripheral nerve cells in the prior art. Changes, complex operation, low adaptability, affect the growth efficiency of peripheral nerve cells, and the nerve conduit is prone to blockage, which blocks the transmission of electromagnetic signals and the light of the LED irradiator, affecting the growth quality and growth effect of peripheral nerve cells question
