Intracerebral minimally invasive microscale multi-target-point injection system for stereoscopic direction navigation equipment

Abstract

The invention discloses an intracerebral minimally invasive microscale multi-target-point injection system for stereoscopic direction navigation equipment. The intracerebral minimally invasive microscale multi-target-point injection system comprises a needle core and an external sleeve needle tube sleeving the needle core, an injection needle end protection sleeve is arranged at the front end of the external sleeve needle tube, a connecting piece is inserted in the rear end of the external sleeve needle tube, a metal connecting piece is connected at the rear end of the connecting piece, the part where the front end of the needle core is connected with the external sleeve needle tube takes the shape of a round blunt nose, a handheld piece is connected to the rear end of the needle core, a rotatable transparent liquid carrier tube connecting piece is arranged in the metal connecting piece in a penetrating manner, and the rear end of the transparent liquid carrier tube connecting piece is connected with a connector of a micro-injection pump through a transparent liquid carrier tube. The intracerebral minimally invasive microscale multiple-target-point injection system has the beneficial effects that the intracerebral minimally invasive microscale multiple-target-point injection system has the advantages of minimally-invasive microscale visual controllable multiple-target-point stereoscopic injection.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a minimally invasive micro-volume multi-target injection system for stereotaxic navigation equipment. Background technique [0002] Directly injecting drugs into local lesions in the brain can treat brain diseases. A common clinical practice is to use ordinary intracerebral puncture needles (2-3mm in diameter, 19cm in length) and stereotaxic navigation equipment to inject radionuclide single-target into the brain. In cystic neoplastic lesions in the brain, in order to achieve the purpose of local radiotherapy. Use an ordinary syringe to connect the above-mentioned puncture needle and then inject the drug. The volume of the injected drug is usually greater than 500ul, and the therapeutic drug of this volume cannot be directly injected into the brain parenchyma, because a large injection volume will produce a slight mass effect. It causes secondary damage to the brain pa...
