Description
Technical Field
The invention belongs to the field of medical instruments, and particularly relates to a suction punching positioning device for intracranial hematoma.
Background
Spontaneous cerebral hemorrhage is a clinically common type of stroke, the mortality rate and the disability rate of the stroke are high, and an effective treatment method is lacked at present. Current studies show that craniotomy hematoma removal surgery is more traumatic and does not significantly improve the functional prognosis of patients compared to conservative treatments. Therefore, such a procedure is not routinely recommended in current clinical work. The minimally invasive intracranial hematoma aspiration has small wound and simple operation, and is conventionally developed in a plurality of hospitals at home at present. The key techniques of the operation are hematoma positioning, skull drilling and drainage tube implantation. The procedures and methods of operation vary from hospital to hospital or regional to regional. Some hospitals adopt a neurosurgical craniocerebral operation three-dimensional positioning system, the positioning is more accurate, but the operation is more complex, the price is high, and the wide popularization is not easy; some hospitals adopt simpler positioning methods, such as CT plain film measurement positioning and bedside puncture, the method has higher requirements on the experience of surgeons, and in the operation process, because the anesthesia depth of a patient is shallow, a fixing device is not firm, the head is often moved, so that the positioning is inaccurate. In addition, the use of pistol drills has the following disadvantages: 1. due to the separability of the scalp and the skull and the vibration of a drill bit of a pistol drill, the position of the scalp is changed, and the skull punching position cannot be preset according to the scalp judgment; 2. after the punching is finished, the punched position cannot be judged from the scalp due to the change of the position of the scalp, so that the operation time is prolonged or secondary punching is needed, the pain of a patient is increased, and the corresponding risks of infection and bleeding are increased. The invention provides a suction punching positioning device for intracranial hematoma, aiming at the problems that the existing pistol drill cannot accurately punch a skull and the head of a patient is difficult to fix in an operation.
