Abstract
The utility model discloses a kind of puncture drainage trocar for intracranial hematoma, it comprises puncture needle and drain trocar sheath two parts composition; Described drain trocar sheath is threeway needle body, and this threeway needle body is provided with draining hole, and there is opening the front end of described drain trocar sheath, and described puncture needle can stretch out from described opening; The rear end of described drain trocar sheath has hygiene cover; The needle section of puncture needle has blade, and described blade can shred hematoma, and being shredded the hematoma block diminished is derived by drain trocar sheath.The hematoma clearance rate of this puncture drainage trocar is high, and wound is little, simple to operate.
Description
Technical field
This utility model relates to a kind of puncture drainage trocar for intracranial hematoma, belongs to technical field of medical instruments.
Background technology
The puncture needle for intractanial hematoma of current Clinical practice all adopts metal brain pin, its limited location and lack variation, drainage effect will be caused bad when hematoma location is inaccurate or hematoma is excessive, if repeat multiple bearing, puncture and drainage, patient's brain damage in meeting man; Meanwhile, because drain caliber is little, easily by clottage.Following shortcoming is there is: the direction of drainage tube and the degree of depth can not be regulated flexibly to arrive any position drain of hematoma, drainage effect may be caused not good in actual operation, and, can not fragmentation be carried out for large hematoma thus carry out drain.
Utility model content
This utility model overcomes above-mentioned shortcoming, provide one and can improve clinical treatment success rate and safety, hematoma clearance rate is high, the puncture drainage trocar for intracranial hematoma that wound is little, simple to operate, can be applied to intracranial hematoma or hydrocephalic Intracranial puncture and drainage.
Of the present utility modelly to be achieved through the following technical solutions: a kind of puncture drainage trocar for intracranial hematoma, it comprises puncture needle and drain trocar sheath two parts composition; Described drain trocar sheath is threeway needle body, and this threeway needle body is provided with draining hole, and there is opening the front end of described drain trocar sheath, and described puncture needle can stretch out from described opening; The rear end of described drain trocar sheath has hygiene cover; The needle section of puncture needle has blade, and described blade can shred hematoma, and being shredded the hematoma block diminished is derived by drain trocar sheath.Such structure all can carry out effective drain to larger hematoma or location hematoma slightly devious.
Accompanying drawing explanation
Fig. 1 is puncture drainage trocar design figure of the present utility model.
Fig. 2 is the local structural graph of the puncture drainage trocar of the present utility model.
Fig. 3 is the Local map of puncture needle of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Embodiment: as Figure 1-3, for the puncture drainage trocar of intracranial hematoma, comprises puncture needle 1 and drain trocar sheath 2 two parts composition; Described drain trocar sheath 2 is threeway needle body, and this threeway needle body is provided with draining hole 4, and there is opening 6 front end of described drain trocar sheath 2, and described puncture needle 1 can stretch out from described opening 6; The rear end of described drain trocar sheath 2 has hygiene cover 5; The needle section 8 of puncture needle 1 has blade 7, and described blade 7 can shred hematoma, and being shredded the hematoma block diminished is derived by described drain trocar sheath 2; Described blade 7 is provided with multiple recess 9, and this recess 9 is triangle or other shapes, and recess 9 can help better to cut hematoma block; Described needle section 8 can be cylindrical or taper or the two combination; Described puncture needle 1 has needle handle (not shown), and needle handle can operate puncture needle 1; Drain trocar sheath 2 outer wall is provided with length groove mark 3; The material of drain trocar sheath 2 can adopt transparent; Described opening 6 can be arranged at an angle with described drain trocar sheath 2, such as 30 degree.
Bore cranium Post operation, under CT stereotaxis, puncture needle 1 is inserted haematoma cavity, by rotating the handle of puncture needle 1, by the blade 7 of puncture needle 1 and recess 9, hematoma block is cut into rapidly less hematoma block, in art, cutting and grinding enter the hematoma block in drain trocar sheath 2, make hematoma drain more unobstructed, thorough; Avoid postoperative deviation and exacerbate injury of again inserting drainage tube.
Above concrete mode of the present utility model is described.Description herein for utility model is illustrative, and thus, scope of the present utility model should not be limited to above-mentioned detailed description of the invention.It will be apparent to one skilled in the art that when not departing from purport of the present utility model or substitutive characteristics, other distortion being carried out to above-mentioned detailed description of the invention or changes, also should be considered as protection domain of the present utility model.
