Description
Technical field
This utility model relates to a kind of intracranial hematoma and pulverizes puncture needle, in particular for the special equipment of intracranial hematoma microscopic wound dissection.
Background technology
At present, known intracranial hematoma is pulverized puncture needle and have following defective in clinical practice: (1) parts too much and critical piece by being threaded, substitute, loading and unloading are loaded down with trivial details time-consuming; (2) sealing is poor, and puncture needle needle body pipeline is not done any processing, finishes that puncture or hematoma are pulverized, after the flushing, withdraw from drill bit or screw out hematoma when pulverizing pin, the external world directly communicates with cranial cavity, and air enters cranial cavity easily and forms pneumoencephalos, and the aseptic condition of operation process also is difficult to be protected; In addition, the medicinal liquid that injects haematoma cavity is also excessive easily, influences the liquefaction effect of hematoma; (3) it is poor that hematoma is pulverized the pin crushing effect, can not do directed the pulverizing.Hematoma is pulverized pin and can not be rotated, and the liquid stream of injection is omnibearing, non-unidirectional, can not do directed the pulverizing, and it is not enough to cause the many orientation of hematoma to be pulverized easily, and few orientation over grind, injured brain tissue; (4) to the little hematoma puncture low precision in deep.Can only do free-hand puncture, can not with the supporting use of stereotaxic frame, be difficult to accurate puncture for the less hematoma at positions such as deep hematoma such as base joint district, cerebellum, easily cause the mistake damage.(5) syringe needle is approximate flat mouthful, when epidural hematoma is removed easily by cerebral dura mater and clot shutoff.(6) needle body drain side pipe becomes an angle of 90 degrees with needle body pipeline pipe, be unfavorable for the drain of hematoma, and also can oppress scalp, and drain side pipe appearance is shiny surface that insecure with being connected of flexible pipe, flexible pipe easily comes off, and increases to infect and risk that ambient atmos enters intracranial.
Summary of the invention
The purpose of this utility model is at above-mentioned drawback, proposes a kind of puncture needle that can implement puncture, removing quick, simple and direct, accurately and efficiently to intracranial hematoma.
The technical scheme that its technical problem that solves this utility model adopts is: this utility model is bored by needle body, core and hematoma pulverizing pin is formed, it is characterized in that: needle body is provided with unidirectional flap valve, the periphery of unidirectional flap valve is provided with annular groove, and the annular groove outside is provided with groove; Core bores and is provided with projection, and after core bored and inserts needle body, projection and groove were chimeric mutually; Hematoma is pulverized pin and is provided with interior annular fixture block and outer ring fixture block, and after hematoma was pulverized pin insertion needle body, inside-and-outside ring fixture block and groove were chimeric mutually, and the backshank that hematoma is pulverized pin is provided with a horn mouth.
Described piercing needle is provided with a groove, and drain side pipe and needle body centrage are 120 degree angles approximately, and its tail end is provided with teeth groove; The core drill bit becomes blunt round, and core bores tail end and is provided with screw thread, is convenient to be connected to go the stereotaxis puncture with finder; Hematoma is pulverized syringe needle and is about 4mm than needle body, and it is half-cylindrical that the part that grows is, and the front end sealing is provided with two row, triplex row micropore at least in planar side.
The beneficial effects of the utility model are: (1) is simple for structure, and parts are few, 4 parts only when doing free-hand puncture; (2) good airproof performance, unidirectional flap valve on the needle body that punctures can prevent that outside air from entering cranial cavity and injecting overflow of drug fluid, and it is convenient to pulverize, wash with postoperative in the art, and aseptic condition is ensured; (3) liquid stream of hematoma pulverizing pin injection is directed liquid stream, pulverizes pin and can do 360 ° of rotations under the condition that keeps sealing on needle body, is convenient to implement orientation pulverizing hematoma, improves crush efficiency, alleviates brain tissue impairment; (4) core bores and needle body employing embedded junction integrator, and is easy to loading and unloading, quick; (5) hematoma pulverizing pin backshank is a horn mouth, need not to connect flexible pipe, but flushing of direct injection liquid or injectable drug; (6) puncture needle drain side pipe has teeth groove, with being connected firmly of flexible pipe, convenient, guarantee postoperative due to illness restless, the out-of-bed activity of people or pass in drainage tube do not come off; (7) angle of puncture needle body and its draining hole is 120 °, is convenient to the drain of hematoma, also can not oppress scalp simultaneously; (8) have the finder that is connected with the stereotaxis frame, guarantee accurate puncture the deep hematoma.
