Description

Skull fixing nail capable of measuring thickness of skull

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a skull fixing nail capable of measuring the thickness of a skull.

Background

For the operation requiring craniotomy, when the bone flap is reset, artificial implantation materials except sutures are often required to ensure accurate skull alignment, so that the occurrence of postoperative bone flap displacement is reduced. For children, the material is firm and the influence on the natural growth of the skull is reduced as much as possible, so that some manufacturers develop absorbable skull fixing nails with absorbable polyester materials as main materials. The product consists of two opposite absorbable connecting sheets and non-absorbable suture lines, wherein one side of each connecting sheet facing exposed bones is provided with a serrated edge for occluding the skull, and each connecting sheet and each suture line are provided with two symmetrical plastic columns for anchoring each connecting sheet and each suture line.

The existing absorbable skull fixing nail can overcome the problem that the metal connecting sheet cannot absorb and limit the growth of the skull. However, the skull of children patients has large thickness difference (which is a very different place from adults), in the diseases that can have extensive or local intracranial pressure increase, such as hydrocephalus, arachnoid cyst, craniocerebral suture premature closure, the skull of the children patients is often very thin, and the plastic columns on two sides of the current absorbable skull fixation nail have fixed sizes, so the plastic columns are not suitable for all children patients. For the infant with thinner skull, the connecting sheet can not tightly fix the bone flap and the surrounding skull; the thickness of the skull cannot be measured and a proper skull fixation nail is selected according to the measurement result.

The present utility model addresses the above-described problems by providing a skull anchor that can measure the thickness of the skull.
