Accurate puncture positioning and supporting system for minimally invasive puncture for intracranial hematoma

Abstract

The invention belongs to the technical field of medical instruments, and particularly discloses an accurate puncture positioning and supporting system for minimally invasive puncture for intracranialhematoma. The system comprises two accurate supporters, each accurate supporter comprises a supporting device, the supporting devices comprise bottom plates, supporting plates, first siding plates andsecond siding plates, the first siding plates and the second siding plates are perpendicularly and oppositely arranged on the bottom plates, two sliding holes are formed in the first siding plates and the second siding plates at intervals, top plates are arranged at the top ends of the first siding plates and the second siding plates, studs corresponding to the sliding holes are arranged on the top plates, two nuts are arranged on the studs in a sleeving manner, the supporting plates comprise head supporting plates and pillow supporting plates, two symmetric connecting plates are arranged attwo opposite edges of the head supporting plates and the pillow supporting plates, a sliding hole is formed in each connecting plate, each stud penetrates the sliding hole in the corresponding connecting plate, and each connecting plate penetrates the corresponding sliding hole in the corresponding side plate and is positioned between the two nuts. According to the supporting system, a head of a patient can be flexibly, standardly and horizontally fixed, so that the minimally invasive puncture accuracy of the intracranial hematoma is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of medical appliances, in particular to a precise puncture positioning support system for minimally invasive puncture of intracranial hematoma. 【Background technique】 [0002] Stroke is currently the number one cause of human death, characterized by high morbidity, high mortality, and high disability rate. Among them, the incidence of cerebral hemorrhage is (60-80) per 100,000 people per year, accounting for about 100,000 in my country. 20% to 30% of all strokes, the fatality rate in the acute phase is as high as 30% to 40%, and >30% of the survivors have residual dysfunction; adult cerebral hemorrhage in European and American countries accounts for 10% to 20% of all strokes, and the mortality rate is as high as 30% to 40%. 23% to 52%. [0003] Based on the limitations of surgical craniotomy on patients with cerebral hemorrhage due to its large trauma, high risk, and rapid reduction of local pressure to ...

Problems solved by technology

However, the accuracy of puncture is not high for doctors with many years of clinical experience, and it is even lower for beginners.

During the operation, the position of the puncture tube is not accurate, which requires multiple punctures and repeated CT scans.

Because the position of the patient's head is not fixed, the standard level of CT scan is not accurate, resulting in inconsistent results of each CT scan, and it is difficult to accurately determine the puncture plane. Even if the puncture plane is determined, if the plane is not perpendicular to the operating table (horizontal plane) , during the process of puncture and catheterization, the pipeline will be biased towards the skull base or the top of the skull, which will also cause low accuracy of catheter placement, and each catheter placement is a new process of re-cannulation. Multiple punctures make the operator, assistant, CT technicians are fatigued, which increases the risk of rebleeding for patients, and family members do not trust them, etc.
