A kind of hematoma clearance device
Technical field
The invention belongs to medical instruments field, specifically, relate to a kind of hematoma clearance device of clinical practice.
Background technology
At present in the cerebral hemorrhage treatment, usually adopt the broken adsorption technology of intracranial hematoma clinically, this technology by suction pump with the hematoma cutting and grinding after sucking-off, suction pump connects the balance lavage apparatus under the continuous negative pressure simultaneously, by the hematoma of broken suction after filtering, injects intracranial simultaneously, keep the volume of haematoma cavity can not change, reach the purpose of removing hematoma, otherwise can cause brain tissue impairment easily because intracranial pressure changes.
But the common hematoma clearance device of using clinically, its suction pump is nonconcentric(al) double layered tubular structure, comprise outer tube and interior pipe, outer tube fills with hydraulic fluid, and front end has the working hole of liquid outlet and cutter head, and outer tube is used for injecting liquid to intracranial, interior pipe is connected with filter, be used for the drawing hematoma piece, be provided with the blade of rotating shaft in the interior pipe, be used for the hematoma piece smashed and be convenient to sucking-off.
But the suction pump processing technology more complicated of this structure also needs a blade that is used to smash the hematoma piece is set separately in interior pipe, has so just increased the caliber of whole suction pump, has correspondingly increased useless volume, is unfavorable for the operation of performing the operation; And the imbibing hole of interior pipe can only be opened in the tangent position of inner and outer pipes, a plurality of imbibing holes can not be set, attraction efficient is restricted, influence the effect of whole hematoma clearance operation, be sealed into negative pressure, sealing gland between rotating shaft and the interior tube chamber, very easily cause the contamination of working fluid, postoperative infection is difficult to control, and then influences patient's surgical effect.
