Abstract

A minimally-invasive encephalic multi-parameter detection probe comprises a contact probe located at the front end. The contact probe comprises a rigidity shell and a medical rubber hose. A cavity allowing an optical fiber module to penetrate therein is formed inside the rigidity shell. An annular groove is formed in the end of the rigidity shell. The optical fiber module comprises an optical fiber and an annular leather plug fixed to one end of the optical fiber. The end, not sleeved with the annular leather plug, of the optical fiber module penetrates into the front end of the rigidity shell till the annular leather plug completely enters the annular groove to form a completely-sealed front-end contact probe contact. A first notch is formed in the side wall of the rigidity shell. A pressure sensor is arranged inside the first notch. The medical rubber hose is arranged at the rear end of the rigidity shell and used for wrapping a signal line guide pipe and an optical fiber inside the rigidity shell and connected with a rear-end processing module. The minimally-invasive encephalic multi-parameter detection probe is used for monitoring encephalic multi-parameter indexes in real time.

Description

technical field

[0001] The invention belongs to the field of implantable medical systems, in particular to a minimally invasive intracranial multi-parameter detection probe. Background technique

[0002] 20% of traumatic brain injury (Traumatic Brain Injury, TBI) patients will have sequelae, and this group of people will experience long-term effects of sequelae in later life, which has created a lot of waste of human, material and financial resources. The causes of the injuries include falls, fights, and traffic accidents. Patients with craniocerebral injury often suffer from traumatic brain edema (Traumatic Brain Edema, TBE) or intracranial hematoma, which will increase intracranial pressure (ICP), decrease cerebral blood flow, aggravate brain injury and lead to patient death. Clinically, the main monitoring indicators of traumatic cerebral edema are ICP and CBF. Problems to be solved urgently in the diagnosis and treatment of traumatic cerebral edema include: the lack of...

Embodiment Construction

[0036] The present invention will be further described in detail according to the specific embodiments of the accompanying drawings.

[0037] Such as figure 1 and figure 2 As shown, the present invention uses dual optical fibers as the sending and receiving paths of near-infrared light. And the double optical fiber is packaged in its envelope, which is convenient for the subsequent threading process. One end of the double optical fiber and its envelope is sleeved in the annular leather plug and fixed.

[0038] Such as image 3 , which shows a side view of all components except the fiber optic module.

[0039] Such as Figure 4 As shown, the end of the optical fiber module that is not covered with the ring-shaped leather plug is inserted through the front end of the titanium alloy housing.

[0040] Such as Figure 5 As shown, the above-mentioned penetrating operation is continued until the ring-shaped leather plug is in full contact with the ring-shaped groove 7 to form...
