Description

Position-variable fixing device applied to surgical head and neck fixation device {Position-variable Fixing Apparatus for Stereotactic Apparatus for Stereotactic Surgery of Brain}

The present invention relates to a position-variable fixation device applied to a surgical head and neck fixation device, and more specifically, to a surgical head and neck fixation device that is rotatable in multiple directions and allows the position of a stereotaxic surgical tool to be changed more precisely. This relates to the position-variable fixation device applied.

For patients suffering from brain diseases such as cerebral hemorrhage, brain tumor, and brain abscess, stereotactic brain surgery can remove the bleeding, biopsy tissue, or remove the abscess without craniotomy. In order to safely perform stereotactic brain surgery, it is important to fix the patient's skull using fixation pins and accurately reach the location of the lesion identified by MRI.

In response to this, as in prior literature 1, a medical power transmission unit capable of moving the position of the fixation pin in multiple directions and a surgical head and neck fixation device using the same have been developed, but the fixation pin itself cannot be moved, so the position of the fixation pin There is a problem that it takes some time to adjust, which can affect the surgery time.

In addition, Prior Literature 2 discloses a stabilizing device that can rotate a part of the fixing pin and thus relatively efficiently control the position of the fixing pin. However, the position of the fixing pin can only be controlled in the left-right or rotational direction. There is a problem that it is not suitable for use when the fixing pin must be moved upward to fix a relatively large skull.
