Description

Positioning device for trigeminal neuralgia minimally invasive surgery

Technical Field

The utility model relates to the technical field of medical equipment, in particular to positioner is used in prosopalgia minimal access surgery.

Background

Trigeminal neuralgia comprises primary trigeminal neuralgia and secondary trigeminal neuralgia, and the pain part is positioned on the craniofacial part innervated by trigeminal nerve. Once the attack occurs, the patient often suffers from sudden and severe pain, seriously affecting the life quality of the patient and being known as 'first pain in nature'. The existing treatment methods comprise craniotomy trigeminal nerve microvascular decompression, radio frequency electrocoagulation ablation and trigeminal ganglion balloon compression. In comparison, the craniotomy has higher cure rate, but has large wound, high operation requirement and more complications. Therefore, the treatment by radiofrequency ablation and balloon compression is most commonly accepted by patients, and although the cure rate is slightly lower than that of craniotomy, the treatment has the advantages of small wound, low cost, repeated implementation once the surgery is relapsed, and the like. However, there are two major problems to be overcome when these two surgical methods are performed. Firstly, an operator needs to accurately position the foramen ovale in a three-dimensional space in terms of operation skill; secondly, the risk of intracranial infection is avoided by strict aseptic manipulation.

Puncture location of the foramen ovale is one of the important steps of the operation, but because the position of the foramen ovale is deep at the skull base, important blood vessels and nerves are arranged beside the foramen ovale, and the individual difference of the patient is added, the puncture failure can be caused by the location according to experience, and the repeated puncture can cause additional damage to the patient and even serious complications of the face hematoma.

The current common accurate positioning method is to perform positioning correction through multiple times of fluoroscopy or three-dimensional CT in the operation, but the exposure of multiple times of X-rays prolongs the operation time, increases the economic burden and aggravates the radiation injury of patients and surgeons. The trigeminal ganglion behind the foramen ovale is positioned in the Mac sac, and the Mac sac cavity is normally opened during operation, and the oral cavity and the nasal cavity in the operation area are all polluted areas, so that intracranial infection is easily caused.
