Multifunctional intracranial hematoma removing deviceTechnical Field
The invention relates to a multifunctional intracranial hematoma removing device, which belongs to the technical field of intracranial hematoma removing medical instruments.
Background
After various craniocerebral injuries and hypertensive cerebral hemorrhages, hematomas of a certain size can be formed in the cranium. Because the size of the skull is relatively fixed, the intracranial pressure is mainly regulated by cerebrospinal fluid and intracranial blood flow, and the regulating force is smaller. After intracranial hematoma is formed, normal brain tissues are directly pressed to cause intracranial pressure to be increased, thereby endangering the life of patients. The traditional treatment method is to perform craniotomy on the patient so as to achieve the aim of removing hematoma. However, the craniotomy requires removing part of the skull, the wound is very large, the recovery is slow, the skull is also repaired after the craniotomy, the cost is high, and especially for the old and weak, the tolerance to the craniotomy is poor. Various intracranial hematoma minimally invasive removal techniques which are clinically adopted at present can relieve hematoma compression, improve circulation and alleviate brain damage, and have certain significance for improving the success rate of treatment and recovering the nerve function after operation. However, the existing minimally invasive clearing device has single function, can not clear the coagulated hematoma effectively, has complex operation, needs to change an external connection mode when the device is required to be flushed and injected simultaneously, and can not reach the bleeding part uniformly due to the injected hemostatic and anticoagulant drugs.

Detailed Description
This multi-functional intracranial hematoma clearing device comprises device body 1, guide bar 2 and visual device 18, and device body 1 is the cylinder structure, and guide bar 2 bottom is equipped with crushing needle 3 admittedly, and guide bar 2 cartridge is in the cylinder of device body 1, and crushing needle 3 of guide bar 2 bottom passes the bottom of device body 1, its characterized in that: a water injection pipe 4, a medicine injection pipe 7 and two drainage liquid suction pipes 10 are manufactured in the cylindrical wall of the device body 1, the four pipes are uniformly distributed at 90 degrees on the circumference of the device body 1, one end of the water injection pipe 4 is connected with a water injection port 5, and the other end of the water injection pipe 4 is connected with a water outlet 6 communicated with the outside and a spraying inclined hole 13 at the bottom; one end of the medicine injection pipe 7 is connected with a medicine injection port 8, and the other end of the medicine injection pipe 7 is connected with a medicine outlet 9 communicated with the outside; one end of the drainage liquid suction pipe 10 is connected with a drainage liquid suction port 11, and the other end of the drainage liquid suction pipe 10 is connected with a drainage liquid inlet 12 communicated with the outside; the water injection port 5 is white, the medicine injection port 8 is yellow, and the drainage liquid suction port 11 is red. The device body 1 sucks drainage liquid through the drainage liquid suction pipe 10 or sucks the drainage liquid through the inner cavity of the cylinder body of the device body 1; or simultaneously aspirates drainage fluid through the drainage fluid aspiration tube 10 and the cylindrical lumen of the device body 1. The bottom of the device body 1 is provided with an injection inclined hole 13 and a central through hole 14, and is provided with two lighting devices 15; the diameter of the injection inclined hole 13 is 1-1.2mm, and the central line of the injection inclined hole 13 is parallel to the central line of the device body 1 and forms an included angle of 40 degrees with the bottom surface of the device body 1. After the guide rod 2 is drawn out of the cylinder of the device body 1, the cylinder is internally provided with a visual device 18, the visual device 18 is connected with an external computer terminal through a connecting wire 19, and the visual device 18 is arranged in the cylinder of the device body 1 or passes through the central through hole 14 and is arranged outside the bottom of the device body 1. When the visual device 18 is placed in the cylinder body of the device body 1, the visual device observes the bleeding part through the central through hole 14 at the bottom of the device body 1. The middle part of the device body 1 is provided with an adhesive sheet 16, and the adhesive sheet 16 is clamped on the device body 1 through an opening 17 on the adhesive sheet 16.
The multifunctional intracranial hematoma removing device is a special instrument for the puncture and drainage of the intracranial hematoma in nerve, surgery and acute, subacute and chronic, and the working process is as follows:
Before use, a drill bit or a rechargeable hand drill is used for selecting proper drilling points according to hematoma positions, drilling is carried out along a puncture direction, dura mater is drilled, then the device body 1 and the guide rod 2 are gradually pushed to the edge of hematoma, after the device body 1 is in place, the adhesive sheet 16 is clamped on the device body 1 through the opening 17, and the device body 1 is stuck and fixed on the scalp from which hair has been removed. And then the cap of the water filling port, the medicine filling port or the drainage liquid suction port is opened according to the requirement, one end of the drainage tube is connected with the port of the opening cap, and the other end of the drainage tube is connected with the injector, so that various liquids can be injected or extracted. When the guide rod 2 is pulled out, the sealing cap is screwed with the port of the device body 1, and then the liquid hematoma can be sucked by the injector through the cylinder inner cavity of the device body 1; therefore, the multifunctional intracranial hematoma removing device can not only suck the drainage liquid through the drainage liquid suction pipe 10, but also suck the drainage liquid through the inner cavity of the cylinder of the device body 1, and can also suck the drainage liquid through the drainage liquid suction pipe 10 and the inner cavity of the cylinder of the device body 1, thereby solving the problem that the traditional hematoma removing device cannot suck the drainage liquid when the guide rod 2 is not pulled out.
When a patient has serious coagulated hematoma, the patient is crushed firstly by the crushing needle 3, water is injected by the injector through the water injection pipe 4, and the water is sprayed out through the spraying inclined hole 13 at the bottom of the device body 1 to form a rotary water disc, so that the coagulated hematoma can be thoroughly cleaned. In addition, the bottom of the device body 1 of the multifunctional intracranial hematoma removing device is provided with the lighting equipment 15, and in the process of removing the intracranial hematoma, an operator directly looks at the removal condition of the intracranial hematoma through the external computer terminal connected with the visual device 18 and the connecting wire, so that the problems that the existing minimally invasive removing device has no lighting function and visual device, can only adopt blind cleaning, and can not thoroughly remove the hematoma, and patients are left with symptoms.
