Abstract
The utility model relates to an intracranial hematoma cleaner, including a tubular hematoma cleaner which is equipped with an Archimedean spiral cutter head, a stereotactic device and a set of hematoma cavity balanced lavage device, the set of the device includes a suction pump, an injection pump, an one-way valve, a liquid container, a motor, a transmission device and a connecting pipeline, the motor can drive the suction pump and a piston of the injection pump to do the synchronized back-and-forth movement by the transmission device, so as to form a circulation of the working liquid, intracranial hematoma can be constantly smashed and extracted out, while the volume can remain unchanged and the intracranial pressure is balanced, thereby avoiding the damage of the cleaner on the normal brain tissues. The hematoma cleaner has higher safety, thorough removal and surgical time can be shortened.
Description
Technical field
This utility model relates to medical apparatus, particularly a kind of intracranial hematoma clearance device of clinical practice.
Prior art
Present cerebral hemorrhage treatment particularly adopt of surgical intervention of hypertensive cerebral hemorrhage is opened cranium removing hematoma more, its weak point is that operation wound is big, particularly deep hematoma treatment, mortality rate and disability rate height, the someone adopts the broken adsorption technology of intracranial hematoma under the stereotaxis in recent years, and certain progress has before been arranged.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.But 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, and this The Application of Technology is very limited.
Summary of the invention
Purpose of design of the present utility model is: avoid deficiency of the prior art, design a kind of safe, remove the remover of intracerebral hematoma thoroughly, apace.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of broken suction balance lavation intracranial hematoma clearance device, the hematoma clearance device that comprises a piped interior dress Archimedian screw cutter head, motor that is connected with remover and Stereotaxic apparatus, it is characterized in that the hematoma clearance device is the double layered tubular structure, this remover is connected with a cover haematoma cavity balance lavage apparatus, this covering device comprises suction pump and injection pump, check valve, liquid container, motor, actuating device and connecting pipe, motor is connected with injection pump in the suction pump that makes its piston make synchronous back and forth movement by actuating device, pass through check valve, the liquid outlet of suction pump is connected with liquid container and hematoma clearance device respectively, and the liquid outlet of injection pump is connected with the outer tube of liquid container and hematoma clearance device.
The operation principle of this hematoma clearance device is, by being synchronized with the movement of injection pump and suction pump, haematoma cavity is extracted out and the amount of liquid of injection equates, form a kind of circulation of hydraulic fluid, make the intracranial hematoma piece when constantly being pulverized and extracting out, its volume is remained unchanged, and intracranial pressure is in poised state, thereby has avoided the injury of remover to normal cerebral tissue.
Be provided with filter between said suction pump and the hematoma clearance device in the technique scheme.The effect of filter is that the hematoma piece of avoiding bigger stops up the transmission pipeline of suction pump.
Said transmission gear for electric motor is made up of variator and leading screw in the technique scheme.
The main component of said liquid is a water in the technique scheme, can add the medicine of dissolving hematoma piece.
Be provided with pressure transducer between said motor and the suction pump in the technique scheme.The effect of this pick off is, takes 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.
Said haematoma cavity balance lavage apparatus can use separately in the technique scheme, also can two the cover use that is connected in parallel.When independent use, the injection of liquid and suction are interrupted to be carried out, and during in parallel the use, the injection of liquid and suction can be carried out continuously, thereby shortens the checkout time of hematoma piece more.
The utility model has the advantages that, one, normal cerebral tissue can be effectively protected in the use, thus improved safety; Two, the removing of hematoma piece is more thorough; Three, elimination efficiency is higher, and operating time shortens.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the bimetallic tube schematic cross-section of hematoma clearance device.
The specific embodiment
The said broken suction balance lavation intracranial hematoma clearance device of present embodiment 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, as shown in Figure 1.The effect of Stereotaxic apparatus is that remover can be aimed at the position of hematoma when guaranteeing puncture, the hematoma clearance device is nonconcentric(al) double layered tubular structure, and interior pipe is equipped with the Archimedian screw cutter head, and outer tube fills with hydraulic fluid, front end has the working hole of liquid outlet and cutter head, as shown in Figure 2.Haematoma cavity balance lavage apparatus comprises suction pump (9) and injection pump (10), check valve (6A), (6B), (6C), (6D), liquid container (10) and (11), motor (7), leading screw (13) and 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, by check valve (6A) and (6B), the liquid outlet of suction pump (9) is connected with liquid container (11) and hematoma clearance device (1) respectively, when piston back-and-forth movement, suction pump (9) can be in the intracranial liquid suction liquid container (11).By check valve (6C) and (6D), the liquid outlet of injection pump (10) is connected with the outer tube (2) of liquid container (12) and hematoma clearance device, very little when piston back-and-forth movement, injection pump (10) can inject intracranial to hydraulic fluid through transfer canal from liquid container (12).Be provided with gauze filter (5) between suction pump (9) and the hematoma clearance device (1), between motor (7) and suction pump (9), be provided with piezoelectric pressure indicator (8).After haematoma cavity internal solid clot was removed, the hydraulic fluid in the drain haematoma cavity finally reached hematoma clearance.
The said haematoma cavity balance of present embodiment lavage apparatus except that motor and actuating device, all uses aseptic disposable plastic to make.
