Surgical positioning device for brain surgery

Abstract

The invention provides a surgical positioning device for brain surgery, which relates to the field of medical equipment, comprising: a base, used to connect with an operating bed; a moving member, relative to the base, moves along three directions perpendicular to each other; The rotating seat is connected with the moving component; the rotating disk is connected with the rotating seat in rotation; the positioning component is connected with the rotating disk and used for positioning the patient's head. According to the surgical positioning device for brain surgery provided by the present invention, the adjustment of the three-coordinate motion of the positioning component and the rotation adjustability of the positioning component by rotation are provided by the moving member, which greatly improves the surgical positioning compared with the prior art. The spatial position and posture of the positioning device can be adjusted during the process, so that the patient's head can be quickly positioned, and the surgeon can be better assisted in the next fine surgical operation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to fast and stable head clamping, in particular to a surgical positioning device for brain surgery. Background technique [0002] Today, craniotomy or craniotomy can be used to treat some brain disorders such as brain injury, brain tumor, head injury, infection of the brain or spine, etc. Craniotomy is also used to relieve cerebral edema, hemostasis, repair blood vessels etc. During the procedure, the surgeon will make an incision on the patient's scalp, make a hole (one or more) in the skull, the surgeon will connect the holes, make a bone flap, remove it, and cut the dura mater to expose the brain tissue and perform surgery. In the treatment operation, the dural incision was sutured to reset the bone flap, and the skull lock was fixed with L-shaped nails. Finally, the scalp incision was closed with U-shaped nails and the scalp was sutured. Craniotomy is completely differen...

Problems solved by technology

[0003] During the operation, the patient's head needs to be stably placed and supported. The existing surgeon's head usually adopts two-point support or a V-shaped block (arc-shaped block) for placing the support. Stable, the head will be vibrated when the skull is drilled (the brain is the most fragile organ of the human body, the skull surrounds the brain to form a hard protective barrier, and the brain has hundreds of millions of neurons, the vibration makes the brain and the skull When the inner wall collides, the brain squeezes the inner wall of the skull to generate a shock wave. The shock wave will tear or pull the axons of some neurons, thereby causing diffuse axonal damage. The damaged neurons will reduce brain function due to axotomy. Depending on the location of the injury, late symptoms may include mental decline, unresponsiveness, language barriers, and many other complications); during the operation, the vibration frequency generated by the external force on the head is likely to resonate with the head support, so place the head support (The surface of the brain is very fragile, like tofu, and it will bleed and cause damage to the brain tissue if it is slightly touched during operation); in addition, if the patient has a brain herniation before the operation and there is no time to do an imaging, it will not be released in time. It will affect the life of the patient, and the hematoma should be removed as soon as possible by craniotomy to solve the brain herniation and save the patient's life. In reality, the patient's body cylinder size is different, such as fat or thin, long or short neck, and different head circumferences. , the traditional head support device has very poor adjustability in spatial posture and posture, and needs to move the patient repeatedly or change different types of head support devices repeatedly. The head placement process is cumbersome, and it is impossible to quickly position and support the head
