Description

Nerve intervention closed aspirator for taking thrombus in acute stroke

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a nerve intervention closed aspirator that is used for taking bolt in acute cerebral apoplexy.

Background

Acute thrombotic stroke is a common disease seriously threatening human health, and the treatment methods mainly comprise venous thrombolysis, arterial thrombolysis and mechanical thrombus removal. For patients who are not suitable for thrombolysis or who fail to thrombolysis, mechanical thrombolysis can achieve a good effect, and compared with thrombolysis, the mechanical thrombolysis method has the advantages of being fast in recanalization time and high in recanalization rate.

Mechanical embolectomy is a means of removing the matter that has been tied to the cerebral vessel. If the blood vessel is unobstructed, the brain cells obtain much blood flow, and cerebral infarction cannot occur. If the blood vessel is blocked by thrombosis or foreign embolus, the blood vessel is occluded, and the brain tissue corresponding to the blood vessel will die slowly after the blood flow is absent. Under the condition of brain cell apoptosis, an acute operation is needed to take out the matters blocking the blood vessels by an operation method, the blood vessels are recovered and recanalized, and brain cells and brain tissues which are not completely necrotic can be slowly recovered by blood flow after recanalization, so that hemiplegia can be avoided and life can be saved.

Mechanical embolectomy is commonly used for neurosurgical suction apparatuses, but the existing neurosurgical suction apparatuses have the following defects: 1. the volume of the aspirator is only 15-25ml, and the volume of the aspirator is insufficient for patients with serious thrombus blockage; 2. the pressure gauge on the aspirator can only monitor the positive pressure value, can not monitor the negative pressure value in the suction process, and is not easy to protect the blood vessel of the patient.

Detailed Description

As shown in figure 1 and figure 2, the utility model discloses a nerve intervention closed aspirator for taking bolt in acute cerebral apoplexy includes the syringe, and the syringe includes barrel 11, and the one end of barrel 11 is equipped with injection head 12, has set gradually interconnect's piston 21, piston shaft 22 and piston handle 23 in the barrel 11, and piston handle 23 is the T font, the application of force of being convenient for. The piston handle 23 is also provided with an anti-drop hook ring 24. When the piston handle 23 is pushed or pulled, a finger can be inserted into the anti-drop hook ring 24 to prevent the hand from separating from the injector.

The cylinder 11 is provided with scale marks 13, the volume of the cylinder 11 is 60ml, the maximum scale of the cylinder 11 is 60ml, the cylinder 11 is provided with a positive pressure gauge and a negative pressure gauge 16, the piston shaft 22 is provided with a positioning elastic sheet 25, the positioning elastic sheet 25 is provided with a plurality of positioning elastic sheets and uniformly distributed on the periphery of the piston shaft 22, the positioning elastic sheet 25 is obliquely arranged towards the piston 21, the bottom of the positioning elastic sheet 25 is fixed on the piston shaft 22, the top of the positioning elastic sheet 25 is a free end and is tightly attached to the inner wall of the cylinder 11 in a natural state, when the piston handle 23 is pushed and pulled, the positioning elastic sheet 25 is pressed to be separated from the inner wall of the cylinder 11, and after the position of the piston 21 is determined, the; symmetrical ear plates 14 are arranged at the opening of the cylinder body 11, and anti-skid grains are arranged on the ear plates 14; the anti-slip ring 15 is arranged in the middle of the barrel 11, when an assistant holds the barrel 11, the assistant generally holds the middle of the barrel 11 with one hand and pushes and pulls the piston handle 23 with the other hand, so that the anti-slip ring 15 arranged in the middle of the barrel 11 and the T-shaped piston handle 23 can help to prevent falling off when pushing and pulling.
