System for assisting head precision surgery positioning

Abstract

The invention relates to a system for assisting head precision surgery positioning, belonging to the technical field of medical treatment. The system comprises a chair, stereotactic frames, a connecting support frame, a projector support and a scintigram projector, wherein the projector support comprises an extension tube and a metal shaped flexible hose; the extension tube is installed on the top wall of a backrest of the chair, and the metal shaped flexible hose is installed at a telescopic end of the extension tube; the scintigram projector is installed at the other end of the metal shaped flexible hose; the connecting support frame comprises stand columns, a lifting cross rod and telescopic support rods; the stand columns are installed on the top wall of the backrest, the lifting cross rod is installed on the stand columns in a way of sliding up and down, and the telescopic support rods are connected to the lifting cross rod; the stereotactic frames are installed at the ends of the telescopic support rods. After the structure is adopted, the connecting support frame is used for substituting manpower so as to complete the work of supporting the stereotactic frames, so that the support is stable, and deviation is not caused; the scintigram projector is installed at the position closer to an attending doctor, thus being convenient to adjust.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a system for assisting precise surgical positioning of the head. Background technique [0002] When performing precise brain surgery on patients with brain diseases, it is usually necessary to fix the patient's head, thus resulting in a stereotaxic frame, which is provided with fixation nails and ring-shaped or square connecting frames. At the same time, the fixing nails are connected to the ring or square connecting frame, and then the fixing nails are nailed to the patient's head, and then the position of the ring or square connecting frame needs to be fixed to prevent the stereotaxic frame from shifting during use , and after fixing the patient's head, it is necessary to project the patient's head scan picture (MRI or CT picture) on the exact position of the patient's head with a scan chart projector connected to the host computer, so that the attending doctor can The pictur...

[0003] Yet the existing stereotaxic frame usually is fixed by a plurality of nurses holding with hands when fixing, and there are following drawbacks in this kind of method: 1, in the process of artificial hand holding, because the human body can't keep a posture for a long time. It is not moving, so it will inevitably cause a slight deviation of the stereotaxic frame, which will affect the progress of the operation; 2. Since the stereotactic frame has a certain weight, in order to minimize its deviation during use, and to fix it for precise operation Nails usually require several nurses to hold the stereotaxic frame at the same time, which is inconvenient to operate and requires a lot of labor costs

And the scanning image projector in the prior art is usually installed in a position far away from the operating table, which is inconvenient for doctors to operate
