Embodiment 1

[0016] Example 1, such as Figure 1-Figure 2 As shown, the early hematoma minimally invasive removal system for intracranial hemorrhage of the present invention consists of two parts: a puncture catheter system and a hematoma ultrasonic comminution mechanism. The puncture needle core 2, the outer diameter of the puncture catheter body 1 is 6-7mm, and the inner diameter is 4-5mm. The position of the puncture catheter body 1 near its tail end is provided with a suction branch pipe 1a, and the center of the suction branch pipe 1a The line is perpendicular to the center line of the puncture catheter body 1, a sealing cover 3 is installed on the nozzle of the suction branch pipe 1a, and a pressure gauge 7 is installed on the suction branch pipe 1a, and the front end of the puncture needle core 2 is bullet-shaped. , the puncture needle core 2 is provided with drainage holes along its length direction, and the front end of the puncture needle core 2 protrudes from the front end of th...

Abstract

The invention discloses an intracranial hemorrhage early-stage hematoma minimally invasive elimination system, comprising a puncture catheter system and a hematoma ultrasonic crushing mechanism, wherein the puncture catheter system comprises a puncture catheter body and a puncture needle core which is movably sleeved inside the puncture catheter body; an internal diameter of the puncture catheter body is 4-5 mm; a suction branch pipe is arranged at the position of the puncture catheter body, which is close to the tail end of the puncture catheter body; a sealing cover is mounted on the pipe opening of the suction branch pipe; the front end of the puncture needle core is bullet-shaped, and extends out the front end of the catheter body; the hematoma ultrasonic crushing mechanism comprises an ultrasonic crushing vibrator and an ultrasonic vibration rod connected with the ultrasonic crushing vibrator; the ultrasonic vibration rod is more than the puncture catheter body in length; and a thread is arranged at the front part of the ultrasonic vibration rod. The intracranial hemorrhage early-stage hematoma minimally invasive elimination system provided by the invention is simple in structure; and the puncture catheter body can conveniently puncture a catheter into a cranium, and is difficult to block. Compared with the conventional puncture catheter, the intracranial hemorrhage early-stage hematoma minimally invasive elimination system can more easily and naturally lead hematoma, so that the damage and the haemorrhage on brain tissues by the conventional mechanical crushing can be avoided.

Description

technical field [0001] The invention relates to a medical device, in particular to a minimally invasive clearing system for early hematoma of intracranial hemorrhage. Background technique [0002] Cerebral hemorrhage is a common disease, frequently-occurring disease, acute onset, serious condition, high disability rate and mortality rate. There are 800,000 to 1.2 million new cerebral hemorrhage patients in the country every year. As far as Chongqing is concerned, the average time for treatment at the hospital is about six hours from onset to surgery. The intracranial hemorrhage has formed a tough blocky solidified substance, the intracranial pressure is very high, and the patient's life is in danger at any time. At present, the commonly used treatment method is craniotomy to remove the hematoma, but the risk factor of this operation is high, the incision wound is large, the operation time is long, it is not easy to recover, and sequelae are easy to leave after operation. ...
