Description

Technical Field

[0001] The invention relates to the technical field of brain pressure plates, in particular to a brain pressure plate for neurosurgery. Background Art

[0002] A brain pressure splint is a type of medical device and one of the commonly used instruments in neurosurgery. It is mainly used to pull brain tissue, expose deep lesions, and provide a good field of view for deep microsurgery.

[0003] A brain compression plate with application number CN202110043506.0 includes: a metal inner core, the metal inner core is composed of a first metal belt and a second metal belt that are parallel to each other, and one end of the metal inner core is a handle, the end away from the handle is a working end, and the handle and the working end are between the handle and the working end; an adhesive layer, the adhesive layer is arranged on the mutual contact surface of the first metal belt and the second metal belt; a silicone sealing layer, the silicone sealing layer covers the outer surface of the metal inner core. The brain compression plate provided by the device enables medical staff to adjust its bending angle according to surgical needs, so that it can be flexibly applied to a variety of surgical needs, and it works stably, effectively reduces the operator's hand fatigue, and facilitates the smooth progress of the operation.

[0004] During use, the brain compression board is simply heated, for example, by soaking it in warm water. At this time, the glue layer becomes soft due to the heat, and external force is applied to the board body and the working end to make the board body and the working end reach a bending angle that meets the needs of the operation. However, the angle adjustment method of the device is not easy to control, and the adjustment angle is small, which cannot meet the surgical requirements of special situations.

[0005] The application number is CN202011175055.8, a brain pressure plate for neurosurgery, including a holding rod and a replacement head, the top of the replacement head is fixedly connected with an electric pin, the end of the replacement head is rotatably connected with an adapter, a group of pressure plates are slidably connected in the adapter, the side walls of the pressure plates are fixedly connected with pressure sensors, the inside of the holding rod is fixedly connected with an electrical connection hole, an adjustment slide is provided on the outer wall of the holding rod, an adjustment ring is slidably connected in the adjustment slide, the adjustment ring is rotatably connected to the adapter through a linkage rod, the holding rod and the replacement head are clamped, and a timer is fixedly installed in the holding rod. The angle of the pressure plate of the device is simple and convenient to adjust, and the angle of the pressure plate is variable, which is convenient for the operator to use to adapt to the needs of different positions and situations, so that the operator can directly know the pressure and the pressing time, which is conducive to timing adjustment to avoid harming the patient and causing medical accidents.

[0006] The device connects the linkage rod on the holding rod and the adapter seat through a rotating pin. When in use, the holding rod is held and the pressing block is pressed inward. At this time, the adjusting ring can move forward and backward, thereby driving the adapter seat to rotate a certain angle through the linkage rod, thereby changing the angle of the pressure plate to meet the needs of different positions and situations. However, the device does not have a structure for removing dust from the pressure sensor on the outside of the pressure plate. During surgery, because the pressure sensor needs to be attached to the outside of the human skin, the pressure sensor is easily adhered to dust, blood and impurities when in use. These things adhere to the outside of the pressure sensor and easily affect the sensitivity of the pressure sensor, making it impossible to accurately judge the patient's intracranial pressure value.

[0007] Therefore, we propose a neurosurgery brain pressure plate to solve the above problems. Summary of the invention
