Description

Temporal bone styloid process truncator

Technical Field

The invention relates to a medical scalpel, in particular to a temporal styloid process truncator.

Background

The temporal styloid process is a thin and long bony prominence protruding forward and downward from the lower part of the temporal bone, normally ranging from several millimeters to 2.5cm, and is located below the ear. The styloid process syndrome is also called as excessive styloid process, Eagle syndrome and styloid neuralgia. The styloid process syndrome is a general term for symptoms such as foreign body sensation in pharynx, pharyngalgia, reflex earache, head and neck pain, salivary gland, etc. caused by over-long styloid process or abnormal stimulation of adjacent vascular nerves due to the orientation and morphology of the styloid process. For patients with the styloid process syndrome with obvious symptoms and signs, the operation truncates the styloid process as the only treatment mode. Currently, the styloid process is shortened through the external diameter of the neck, no special truncator exists, and the styloid process is broken by clamping the styloid root by a needle holder, so that more problems occur in the process: 1. in the process of fracture, facial nerves and neck blood vessels are held in the needle, and the facial nerves and the neck blood vessels are fractured to cause severe complications such as facial paralysis, hemorrhage and the like; 2. the broken end is acute and uneven, which can cause secondary damage to facial nerve or carotid artery and vein, leading to nerve dysfunction, heavy bleeding and the like 3. the needle holder can not carry out accurate truncation to the styloid process, and the truncation length is different.
