The invention discloses a brain retractor for neurosurgery. The brain retractor comprises a holding rod and a replacement head, wherein electric contact pins are fixedly connected to the top of the replacement head, an adapter is rotatably connected to the end of the replacement head, a group of retractor is slidably connected to the inner part of the adapter, and a pressure sensor is fixedly connected to the side wall of the retractor; and an electric connection hole is fixedly connected to the interior of the holding rod, an adjusting sliding way is formed in the outer wall of the holding rod, an adjusting trigger finger is connected to the inner part of the adjusting sliding way in a sliding mode, the adjusting trigger finger is rotatably connected with the adapter base through a linkage rod, the holding rod is connected with the replacement head in a clamped mode, and a timer is fixedly mounted in the holding rod. The angle of the retractors is simple and convenient to adjust, theretractor angle can be changed, and the brain retractor is convenient for an operator to use so as to meet the requirements of different positions and conditions. The brain retractor is convenient forthe operator to directly know the pressure and the pressed time, is beneficial to timing adjustment, and avoids hurting a patient and causing medical accidents.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a brain compression plate for neurosurgery. Background technique [0002] Brain Retractor is one of the commonly used instruments in neurosurgery. It is mainly used to pull brain tissue, expose deep lesions, and provide a good view for deep micromanipulation. Stretching in brain compression surgery is mainly divided into two types: continuous stretching and intermittent stretching. Continuous stretching usually refers to the continuous stretching of the brain tissue during the operation, and intermittent stretching refers to repeated stretching and relaxation of the brain tissue many times. . The brain compression plate is a rigid structure with sharp edges. In addition, the brain tissue is pulsating. Excessive or inappropriate stretching of the brain tissue can cause different degrees of brain damage such as cerebral edema, brain contusion, cerebral infarction, and cere...
