Inflatable brain retractor and using method thereof

Abstract

The invention discloses an inflatable brain retractor. The inflatable brain retractor comprises a retractor body, a puncture guide needle and a guide needle core, wherein flexible soft materials are adopted for the retractor body to form a hollow structure formed by combining an outer layer membrane and an inner layer membrane, an inflating valve is arranged on the retractor body, the puncture guide needle is a hollow round tube, a wire groove is formed in the circumferential tube wall of the puncture guide needle, the guide needle core is inserted from the middle of the retractor body, and the guide needle core and the retractor body are together guided into the hollow position of the puncture guide needle. Besides, the invention discloses a using method of the inflatable brain retractor. According to the inflatable brain retractor and the using method of the inflatable brain retractor, the inflatable brain retractor can reach the hematoma portion and other operational sites through a puncture operation with smallest injury to the brain tissue, and the operation procedure can be directly observed after the brain tissue is fully expanded by the retractor.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a cranial device for puncturing the hematoma cavity (tumor cavity), retracting and fixing the brain tissue, and maintaining the surgical field after craniotomy for hypertensive cerebral hemorrhage and partial deep tumors in neurosurgery. The invention relates to an operation auxiliary tool, in particular to an inflatable brain retractor for craniocerebral surgery with puncture positioning and operation field maintenance and its application method. Background technique [0002] There are two types of hypertensive cerebral hemorrhage surgery, one is hematoma cavity puncture and drainage, and the other is craniotomy and hematoma evacuation. Transcranial puncture, twisting, drilling, and crushing hematoma evacuation is performed under blind puncture to perform partial hematoma removal and drainage tube placement. The whole process is performed without direct vision, which...

AI Technical Summary

Problems solved by technology

Transcranial puncture, twisting, drilling, and crushing hematoma evacuation is performed under blind puncture to perform partial hematoma removal and drainage tube placement. The whole process is performed without direct vision, which is likely to cause damage to brain tissue and adjacent blood vessels. In case of vascular malformation, etc. Fatal bleeding without effective hemostasis

However, the traditional craniotomy requires manual operation with a retractor. For non-skilled senior physicians, it may be difficult to maintain the surgical field, unstable or even accidentally injure the surrounding normal brain tissue and blood vessels.

[0003] The invention of the U.S. patent product Vycor medical retractor has greatly improved the operation of hypertensive cerebral hemorrhage and is more conducive to minimally invasive hematoma removal. However, electrocautery and incision of the cortex and subcortex brain tissue are still required when using this device In order to reach the hematoma cavity and then insert the retractor, a brain tissue incision about 3-4cm in length and 5-6cm in depth is required during the operation. There is still a certain degree of artificial damage to the brain tissue during the entire operation.
