Low-temperature intracranial hematoma puncturing trocar

Abstract

The invention relates to a low-temperature intracranial hematoma puncturing trocar, which comprises a low-temperature hematoma puncturing drill needle and a drainage sleeve. The upper end of the low-temperature hematoma puncturing drill needle is provided with a drill needle handle, the top part of the low-temperature hematoma puncturing drill needle is provided with a metal plug, a water injection tube is sleeved in the low-temperature hematoma puncturing drill needle, the diameter of the lower part of the water injection tube is smaller than the diameter of the upper part of the water injection tube, a plastic inner core is sleeved in the drainage sleeve, the top part of the drainage sleeve is provided with a cap, the upper part of the drainage sleeve is provided with a side tube, and the lower end of the drainage sleeve is provided with a round blunt opening. By adopting the technical scheme, the high speed of the electric drill can be maintained, the scalp can be prevented from being burnt, blood vessels and nerves can be effectively prevented from being damaged, and the safety and reliability of the micro puncturing treatment of hypertensive intracerebral hemorrhage can be ensured.

Description

technical field [0001] The invention relates to a medical device for minimally invasive puncture treatment of hypertensive cerebral hemorrhage. Background technique [0002] At present, for patients with hypertensive cerebral hemorrhage who have surgical indications, surgical operations and minimally invasive puncture are used. Because surgical operations require general anesthesia and bone flap removal, the surgical damage is relatively large, and most of the patient's family members cannot accept surgical operations. Therefore, a minimally invasive puncture operation with relatively little damage is widely used clinically in the treatment of hypertensive cerebral hemorrhage. There are mainly two methods for minimally invasive puncture treatment of hypertensive cerebral hemorrhage: one is to drill the skull with a hand drill, and place a drainage tube to remove the hematoma; The former is time-consuming and labor-intensive to drill the cranium by hand, and the hose used is...

AI Technical Summary

Problems solved by technology

The former is time-consuming and laborious to drill the skull by hand, and the hose used is easy to break, and the drainage effect is poor

The latter is faster, but because the end of the outer cannula entering the cranium is serrated, there is a risk of cutting blood vessels and nerves when entering the cranium. In addition, when drilling the skull, the friction between the drill bit and the skull generates heat, which is easy to burn Scalp, causing scalp infection and difficult healing of the scalp, etc.
