Description
Technical field this utility model relates to medical apparatus, particularly a kind of intracranial hematoma washer of clinical practice.
In the present cerebral hemorrhage treatment of background technology, more advanced is the broken adsorption technology of intracranial hematoma under the stereotaxis, the stereotaxic apparatus that this technology generally comprises the hematoma clearance device of a piped interior dress Archimedian screw cutter head, the motor that is connected with remover and locatees usefulness for the remover puncture, under the attraction of continuous negative pressure, reach the purpose of removing hematoma by cutting of spiral cutter head and pulverizing blood clot.The weak point of this technology is, because the volume of hematoma piece will change in the process of removing, is difficult to control sucking-off quantity of hematoma and sucking-off scope, causes brain tissue injury easily.A kind of broken suction balance lavation intracranial hematoma washer (patent No. is 02212069.6) can address this problem, and its structure as shown in Figure 1.It comprises the hematoma clearance device (1) of a piped interior dress Archimedian screw cutter head, the motor (4) that is connected with remover, Stereotaxic apparatus (3) and a cover haematoma cavity balance lavage apparatus.The hematoma clearance device is nonconcentric(al) double layered tubular structure, outer tube (2) fills with hydraulic fluid, front end has the working hole of liquid outlet and cutter head, haematoma cavity balance lavage apparatus comprises suction pump (6), injection pump (7), check valve (10), liquid container (11), motor (9), leading screw (8) and corresponding connecting pipe, motor (7) makes the piston of suction pump (9) and injection pump (10) make synchronous back and forth movement by lead screw transmission, be provided with gauze filter (5) between suction pump (9) and the hematoma clearance device (1), effect by check valve (10), suction pump (9) can be extracted intracranial liquid out, and injection pump (10) can inject intracranial to hydraulic fluid.Like this.Just guaranteed stable in the broken suction process of hematoma mesocrany inner volume, thereby the protection cerebral tissue can not sustain damage.
But, the haematoma cavity balance lavage apparatus structure more complicated of this washer, processing and manufacturing acquires a certain degree of difficulty, and breaks down easily, makes troubles to user.
The summary of the invention the purpose of this utility model provides a kind of improved intracranial hematoma washer, and it can have advantage simple in structure, easy to use when guaranteeing the broken suction process of hematoma mesocrany inner volume stable.
The purpose of this utility model is achieved through the following technical solutions: a kind of improved intracranial hematoma washer, the hematoma clearance device (1) that comprises a piped interior dress Archimedian screw cutter head, the motor that is connected with remover (4), a Stereotaxic apparatus (3) and a cover haematoma cavity balance lavage apparatus, the hematoma clearance device is nonconcentric(al) double layered tubular structure, outer tube (2) fills with hydraulic fluid, front end has the working hole of liquid outlet and cutter head, the interior pipe of hematoma clearance device (1) is connected with gauze filter (5), haematoma cavity balance lavage apparatus comprises circulating pump, the hemocyte filter, valve and corresponding connecting pipe, the inlet of circulating pump is connected with the feed tube of liquid outlet respectively at gauze filter (5) and hemocyte filter, and the drain pipe of hemocyte filter is connected with the outer tube (2) of hematoma clearance device (1) by valve.
The main points of this technical scheme are to have increased the hemocyte filter on the basis of existing technology, after the broken suction and pumping of the hematoma of intracranial go out, and the intracranial that partly reinjects of the liquid after the filtration.Like this, the injection pump of synchronous operation and suction pump can be replaced by a circulating pump, and corollary equipments such as check valve, leading screw also can save, thereby structure is greatly simplified.
Be provided with pressure transducer in the pipeline of said connection gauze filter and circulating pump in the technique scheme, the outfan of this pick off is connected with the motor of circulating pump.The effect of this pick off is to take place to stop up or other fortuitous events in pipeline, and the negative pressure in the suction pump surpasses certain limit, in time stops motor rotation, can avoid the haematoma cavity volume to change like this.
The medical filter membrane of multilamellar is equipped with in the inside of said hemocyte filter in the technique scheme.
The purpose that valve is set in the technique scheme is: user can be according to operation progress, opening and closing haematoma cavity balance lavage apparatus at any time.
Be provided with three-way valve in the connecting pipe of said haematoma cavity balance lavage apparatus in the technique scheme.The purpose that three-way valve is set is in order to take the circumstances into consideration to emit a part of liquid in operation is carried out, to reduce intracranial pressure.
Be added with haemolysis medicine, for example urokinase in the technique scheme in the said hydraulic fluid.
The utility model has the advantages that: one, simple in structure, easy to use; Two, specification requirement is low, is not easy to break down; Three, reduced manufacturing cost, be beneficial to and promote the use of.
