The flushing integrated style minimally invasive intracranial hematoma cleaning device integrates suction, injection of bio-enzyme, mechanical cutting and grinding into a whole, so the utility model can be one-off positioned in and fulfill a plurality of operations of suction, injection and mechanical cutting and grinding simultaneously; therefore, the operation can be speeded up and the suffering of patients can be relieved; moreover, by adopting the micro motor for driving, the arc surfaced rotary knife for cutting and grinding and the convex net cover for insolating, the utility model not only can accelerate suction, but also can avoid mechanical injury and prevent bleeding again.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of flushing integral type Wicresoft intracranial hematoma rinser that is applicable to the intracranial hematoma cleaning of Minimally Invasive Surgery.
Background technology
Intracranial hematoma has significant threat to people's life, when hematoma when intracranial occupies certain volume, heavy then cause death, gently then cause the patient invalid, and the course of disease is long more, just big more to the infringement of brain, therefore, in time eliminating intracranial hematoma, is the important means of rescue patient.At present, generally adopt Wicresoft's operation of opening cranium for intracranial hematoma, simultaneously, adopt negative pressure drainage device to carry out aspiration drainage, this negative pressure drainage device, comprise that drainage tube, negative pressure-pumping mouth, aspirator constitute, during aspiration drainage, under CT monitors, drainage tube is inserted into hematoma from Wicresoft's mouth, and aspirator is connected on the negative pressure-pumping mouth by conduit, this negative suction system can directly pump out for the blood lump of liquid state, but the hematoma pathological changes that in clinical, is run into, often except liquid blood, partly solidify in addition or hematoma that curdled appearance is harder.For harder hematoma, there are two kinds of methods to remove at present, the one, mechanicalness is cut the suction of mill back, and the main deficiency that this sweep-out method exists is to cause hemorrhage and injured brain tissue easily again; The 2nd, the sweep-out method of employing injection enzyme liquefaction hematoma, the main deficiency that this sweep-out method exists is that liquefying time is long, needs competence exertion maximum liquefaction after 6 hours, can not carry out simultaneously with suction, each liquefaction amount is limited.
Summary of the invention
The purpose of this utility model is to provide a kind of above the deficiencies in the prior art that overcome, and integrates machinery and cuts mill, injection enzyme, aspirates, and can improve the suction operative speed, safe in utilization again a kind of flushing integral type Wicresoft intracranial hematoma rinser.
For reaching above purpose, the technical scheme that this utility model adopted is: this flushing integral type Wicresoft intracranial hematoma rinser, by outer tube, the spigot joint formation of aspirator, the spigot joint seat end that is vertically fixed on outer tube of aspirator, it is characterized in that being provided with puncture needle along central axis at the intracavity of outer tube, seat end at puncture needle connects the enzyme ascending pipe, establish annular suction inlet at the front end of outer tube, fixing the spirogyrate guard on the annular suction inlet, establish the cambered surface swivel knife in the inboard of spirogyrate guard, the blade of cambered surface swivel knife is adjacent to the medial surface of spirogyrate guard, the radian of cambered surface swivel knife is consistent with the inboard radian of spirogyrate guard, when the cambered surface swivel knife is rotated, cut mill with the mesh of spirogyrate guard along formation, the hard hematoma that to press close to spirogyrate guard mesh or suck its mesh is cut mill, the cambered surface swivel knife is fixed on the outer wall of rotating casing front end, rotating casing tightly is enclosed within on the puncture needle, can rotate for axle by puncture needle, seat end at outer tube is established sealing cap, on sealing cap, establish a left side, right handles, fixing micromachine on the right handles, rotating casing stretches out from the center hole of sealing cap, and the seat end of rotating casing is by the gears engaged on the driving shaft of gear and micromachine.This utility model is also implemented by following measure: be provided with scale on the wall of outer tube, so that in time observe and write down the outer tube insertion depth, encircle deeply by the screw fixed upper limit in the front portion of outer tube, when micromachine was worked, depth limiting ring can play the role of positioning; Scale is also established in rear end at the puncture needle shank, is mainly used in the extension elongation of grasping the puncture needle needle point; Outer tube is a stainless steel tube, and the external diameter of outer tube is 4mm, and internal diameter is 3mm, and length is 20-50mm; The external diameter of puncture needle is 1mm, and the external diameter of rotating casing is 2mm, and internal diameter is 1mm; The ring cavity that 0.5mm is arranged between outer tube and the rotating casing is as drainage lumens; Described micromachine is a prior art, can directly buy, and uses 220 volts of power supplys.When using this utility model, under CT monitors, insert from Wicresoft's mouth, make the tip portion of puncture needle thrust harder hematoma, the one, play the role of positioning, the 2nd, directly enzyme is injected in the harder hematoma by puncture needle, to the softening dissolving of harder hematoma, the 3rd, allow progressively rising of hard hematoma, being convenient to annular suction inlet picks up, the spirogyrate guard is supported to harder hematoma, after insertion depth is adjusted, use the depth limiting ring fixed position, when micromachine rotates, to prevent vibration, be connected enzyme infusion appliance and negative pressure-pumping device respectively on the enzyme ascending pipe with on aspirator is spigot joint, in the liquid hematoma of suction, the harder hematoma of solidifying is injected enzyme, and under the rising combined effect to hard hematoma piece, make hard hematoma press close to the spirogyrate guard at negative pressure suction force and enzyme, the cambered surface swivel knife is rotated, hematoma is cut mill on one side, suction on one side, on one side dissolving, aspiration procedure is accelerated.Begin the suction, the suction Controlled amount be hematoma shared spatial half, should not take out more, prevent again hemorrhage, owing in drawing liquid, injected enzyme, so suction time can prolong, make enzyme more dissolution time be arranged to hard hematoma, after reaching suction and requiring, allow aspirator keep somewhere, repetitive operation is once again after 6 hours at interval, reciprocal successively, till with hard hematoma full scale clearance.
The beneficial effects of the utility model are: with at present the aspirator of intracranial hematoma is compared, because integrate suction, inject enzyme, machinery cuts and grinds, so, can disposablely insert, finish simultaneously take out, notes, mechanicalness cut the multiple operation of mill, so can improve operative speed, alleviate the patient suffering.In addition,, therefore, can not only improve pumping velocity, and can avoid mechanical injuries, prevent again hemorrhage owing to adopt minitype motor driving, cambered surface swivel knife to cut mill, the isolation of spirogyrate guard.
