Method and Apparatus for Treatment of Tinnitus and Other Neurological Disorders by Brain Stimulation in the Inferior Colliculi and/or In Adjacent Areas

InactiveUS20070265683A1Reducing and eliminating effectSuppress and eliminate neural activityHead electrodesImplantable neurostimulatorsPeriaqueductal grayElectrode placement
Electrical stimulation is applied to the inferior colliculus or colliculi (IC), in order to diminish tinnitus by revising auditory pathway neuronal activity. This intervention diminishes tinnitus and treats other neurological and otological disorders. The locations and methods of electrode placement and anchoring and the structure of the electrodes are an advance over prior treatments. Other treatment locations in the nearby region of the IC, including the superior colliculi (SC) and Peri-aqueductal gray (PAG), provide treatments for other disorders and symptoms such as partial hearing loss and pain. The IC is a unique choice for the treatment of tinnitus and other disorders because an electrode placed in that region enables minimal invasiveness. The anchoring location also uniquely minimizes invasiveness by providing the option of residing in the meninges instead of the brain tissue. The shape of the electrode and its anchoring process uniquely match the brain's anatomy in order to provide greater specificity in diagnosis and treatment. Stimulation of areas near the IC, particularly the superior colliculus and peri-aqueductal gray, can be used to treat various neurological disorders. Customized feedback from the implantable system enables the creation of customized treatment programs.

Multifunctional acupuncture three-dimensional teaching model and teaching system thereof

InactiveCN103426352AHandy instructionsRealize local visualizationEducational modelsSpecial data processing applicationsHuman bodyAnatomical structures
The invention discloses an acupuncture teaching model and particularly relates to a multifunctional acupuncture three-dimensional teaching model which comprises a transparent simulation body model and a base, wherein the transparent simulation body model is arranged on the base. All the body organs such as skin tissue, muscular tissue, skeleton tissue, viscera tissue, vascular tissue and brain tissue are arranged on the transparent simulation body model. Body meridian lines and acupuncture points are embedded in the tissue and among the tissue. Leads, light-emitting devices, pressure sensors and acupuncture sensors are arranged in the tissue, the meridian lines and the acupuncture points. A control circuit is arranged on the base. The leads, the light-emitting devices, the pressure sensors and the acupuncture sensors are electrically connected to the control circuit. A central processor is arranged on the control circuit which is connected with an outside computer through an interface. The acupuncture simulation body teaching model and the ordinary computer form a teaching system. A three-dimensional animation simulation body model corresponding to the teaching model and a body anatomical structure database are arranged on the computer, and positions and organs of the three-dimensional animation simulation body model and the body anatomical structure database and positions and organs of the simulation body teaching model are in one-to-one correspondence and form relevance.

Skull replacing apparatus of 3D print and manufacturing method thereof

A skull replacing apparatus of 3D print and a manufacturing method thereof relate to a skull replacing apparatus and a manufacturing method thereof. In order to solve the problem of dysfunction due to the fact that the existing skull replacing object can't satisfy the refine requirement to a patent defect portion so that the cerebral tissue can't be fully protected and the skull replacing object usually doesn't match with the patent skull, the invention provides a skull replacing apparatus. The apparatus comprises a fixation piece, a compact substance layer 1, a compact substance layer 2 and a transitional layer, wherein the fixation piece and the compact substance layer 1 are located above the transitional layer; the compact substance layer 2 is located below the transitional layer and the compact substance layer 1 is connected to the compact substance layer 2 through the transitional layer; the compact substance layer 1, the transitional layer and the compact substance layer 2 have the same shape with the defect skull; and the transitional layer is a micro truss structure. The method comprises: a. imaging the damaged skull with 3D so as to determine the geometry size and parameter of the skull to acquire original datum of the skull needed to be replaced; b. designing a three-dimensional model of a skull replacing structure and printing the designed model; c. and improving the surface of a sample. The skull replacing apparatus and the manufacturing method thereof are suitable for skull replacement.

System and method for non-invasive monitoring of cerebral tissue hemodynamics

A method and system are provided which are useful for the non-invasive determination and monitoring of cerebral tissue oxygenation. The method comprises the steps of generating at least first and second jugular venous output signals against time based on the reflection of at least first and second wavelengths of light, respectively, from an external tissue site on the patient in the proximity of the internal jugular vein; obtaining corresponding first and second cardiac arterial output signals for the first and second wavelengths of light, respectively, from the patient, and separating the first and second cardiac arterial output signals from the first and second jugular venous output signals, respectively, to generate first and second cerebral venous output signals; and determining cerebral tissue oxygenation based on the first and second cerebral venous output signals. A system useful to monitor cerebral tissue oxygenation may comprise a first module for optically generating at least first and second jugular venous output signals against time at at least first and second wavelengths of light, respectively, from the patient; a second module for generating first and second cardiac arterial output signals at the first and second wavelengths of light, respectively, from the patient; and a signal processing means adapted to separate the first and second cardiac arterial output signals from the first and second jugular venous output signals, respectively, to yield first and second cerebral venous output signals, for the determination of cerebral tissue oxygenation.

Visible cerebral ventricle and subdural external drainage system

The invention discloses a visible cerebral ventricle and subdural external drainage system. The visible cerebral ventricle and subdural external drainage system comprises a visible cerebral ventricle puncture system and a drainage system. The visible cerebral ventricle puncture system comprises a visible puncture guiding core, and LED light sources and a miniature camera are coaxially arranged at the intracranial end of the visible puncture guiding core. The wall of a puncture sheath is see-through, and millimeter scales are arranged on the outer wall of the puncture sheath. The visible cerebral ventricle and subdural external drainage system has the remarkable advantages that as the miniature camera can be connected to one end of the visible puncture guiding core, and a monitor is connected to the other end of the visible puncture guiding core, cerebral puncture is completely performed in a direct-viewing mode, precision is improved, and it is avoided that due to operation based on a rule of thumb, the cerebral tissue is damaged, or cerebral hemorrhage occurs. As miniature vanes (fixing clamps) are arranged at the position distant from the cerebral ventricle by 10 cm-15 cm and used for fixing a drainage tube at the incised skin, the defect that a drainage tube used for the current clinic is simply bound and fixed through threads is overcome.
