Slide rail type nerve sleeve and cranial cavity hematoma removal method

Abstract

The invention discloses a slide rail type nerve sleeve and a cranial cavity hematoma removal method, and belongs to the field of cranial cavity surgical instruments, the slide rail type nerve sleeve comprises a funnel-shaped barrel, a circle of circumferential slide way is arranged at the upper end of the funnel-shaped barrel, an endoscope channel is arranged in the funnel-shaped barrel, a connecting block is arranged on the endoscope channel, and the connecting block can drive the endoscope channel to slide along the circumference of the circumferential slide way; the bottom of the funnel-shaped barrel is an integrally-arranged small barrel diameter, the small barrel diameter is arranged to be a double-layer film-shaped object, the double-layer film-shaped object is folded under negative pressure, the interior of the double-layer film-shaped object is adhered by a water-soluble biodegradable adhesive, a channel is formed in the center of an inner-layer film-shaped object of the double-layer film-shaped object and is communicated with an endoscope channel, and an outer-layer film-shaped object of the double-layer film-shaped object is communicated with the funnel-shaped barrel; a flushing hole is formed in the upper end of the funnel-shaped barrel, the middle space between the inner-layer membranous object and the outer-layer membranous object is communicated with the flushing hole, and an air bag is further arranged in the middle space between the inner-layer membranous object and the outer-layer membranous object. Therefore, multi-angle observation is achieved, hematoma can be removed at a time, and the influence of interference between channels on operation is avoided.

Description

technical field [0001] The invention relates to the field of cranial cavity surgical instruments, in particular to a slide rail type nerve sleeve and a method for removing cranial cavity hematoma. Background technique [0002] For the treatment of hematoma inside the cranial cavity, the current surgical method is to first obtain the general location of the hematoma through images, and then use the puncture needle to combine the images to obtain the exact location, and then use the extended needle to remove the hematoma along the channel of the puncture needle. It is often necessary to observe carefully with the help of an endoscope. In order to expand the channel during this process, since there is no special tool, it is often inserted rigidly into the inside, causing certain damage to the brain tissue. Moreover, the above-mentioned operation is very time-consuming and laborious, and the final removal effect is often There is still a certain residue, which brings follow-up t...
