Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly system is known by a kind of intracranial hemorrhage early-stage hematoma Wicresoft.
Background technology
Cerebral hemorrhage is current commonly encountered diseases, frequently-occurring disease, and onset is anxious, state of an illness weight, disability rate and mortality rate high.The annual new carbuncle in the occipital region hemorrhage in the whole nation has 800,000-120 ten thousand.With regard to Chongqing City, carry out institute's treatment time from falling ill to performing the operation on average all at six hours.The hemorrhage of intracranial has formed toughness coagulation of mass material, and intracranial pressure is very large, and patient is in peril of one's life at any time.The therapeutic modality generally used at present is operation of opening cranium, take out hematoma, but this surgical risks coefficient is high, and otch wound surface is large, and operating time is long, not easily gets well, and postoperatively easily stays sequela.The life and health of patient can not be protected.
In recent years, along with the development of Wicresoft's Medical Technology, disposable puncture needle for removing intracranial hematoma is widely used in the treatment of cranium cerebral hemorrhage, significantly reduces the misery of patient.By metallic pin through in cranial cavity, carry out drain, but current cerebral hemorrhage minimum traumatic removes operating theater instruments still many incomplete places, as: surgical catheters and drainage tube internal diameter (3mm) less than normal, the broken suction effect of hematoma crushing aspirating device to hematoma is bad, no matter be automatic jet or initiatively suction, be all easy to by clottage.And in the hematoma application processes such as Wicresoft, find that cephalophyma is made up of the semisolid liquid state of firm blood clotting and small part greatly.Current liquid state can through gently aspirating removing, and firm blood clot can only stir to inhale through mechanicalnesses such as rotating blades and remove.Mechanical system easily causes hemorrhage and brain tissue impairment again.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of intracranial hemorrhage early-stage hematoma Wicresoft scavenging system, not easily cause clottage, effective mechanical vibration bring damage to cerebral tissue.
To achieve these goals, technical scheme of the present invention is as follows: a kind of intracranial hemorrhage early-stage hematoma Wicresoft scavenging system, it is characterized in that: comprise puncture conduit system and hematoma Ultrasonic Pulverization mechanism, described puncture conduit system comprises puncture catheter body (1) and the puncture needle core (2) of kink in puncture catheter body (1), the internal diameter of described puncture catheter body (1) is 4-5mm, described puncture catheter body (1) is provided with suction branch (1a) near the position of its tail end, the mouth of pipe of this suction branch (1a) is equipped with seal cover (3), the front end of described puncture needle core (2) is bullet-shaped, and stretch out the front end of catheter body (1), the Under Ultrasonic Vibration lever (5) that described hematoma Ultrasonic Pulverization mechanism comprises Ultrasonic Pulverization vibrator (4) and is connected with Ultrasonic Pulverization vibrator (4), the length of described Under Ultrasonic Vibration lever (5) is greater than the length of puncture catheter body (1), the front portion of described Under Ultrasonic Vibration lever (5) is provided with screw thread (6), during use, puncture conduit system is allowed to enter assigned address, again the puncture needle core (2) in the catheter body that punctures (1) is exited, described Under Ultrasonic Vibration lever (5) is placed in puncture catheter body (1).
Adopt technique scheme, the caliber of puncture conduit expands by the present invention, kink puncture needle in puncture conduit, the Front-end Design of puncture needle becomes bullet-shaped, reduce to enter bore, such one side convenient puncture conduit enters intracranial, and the caliber expansion of puncture conduit is more easily fixed than existing puncture conduit on the other hand, not easily results in blockage; Drain arm is set separately, natural drain hematoma easier in existing puncture conduit.After puncture conduit enters intracranial, can aspect puncture needle core be exited, then Under Ultrasonic Vibration lever is placed in puncture conduit, the front end of Under Ultrasonic Vibration lever is stretched out outside puncture conduit, arrive Hemorrhagic location, Ultrasonic Pulverization is carried out to hematoma, avoids existing mechanical activation comminution to bring new injury and hemorrhage to cerebral tissue.Screw thread is established in Under Ultrasonic Vibration lever front end, melts broken for hematoma, accelerates hematoma liquefaction and discharges.
In technique scheme: inner surface and the outer surface of described puncture catheter body (1) all scribble one deck antibiotic layer.Good leak tightness, avoids infection.
In technique scheme: described puncture catheter body (1) is made up of Ti-Ni alloy.Fineness is better.
In technique scheme: the centrage of described suction branch (1a) and the central axis of described puncture catheter body (1), suction branch (1a) is equipped with Pressure gauge (7).During nature drain, device is furnished with Instrument for Pressure, and sustainability observes intracranial pressure change, monitored patient situation.
In technique scheme: the length of described Under Ultrasonic Vibration lever (5) is 60-100mm, and diameter is 1.5-3mm, the length of the thread segment that it is threaded (6) is 1/1 to three/5th of whole length.
In technique scheme: the external diameter of described puncture catheter body (1) is 6-7mm.
Beneficial effect: structure of the present invention is simple, the puncture catheter body conduit that can conveniently puncture enters intracranial, not easily results in blockage, more easily draws nature bleed swollen than existing puncture conduit, avoids existing mechanical activation comminution to bring new injury and hemorrhage to cerebral tissue.
