Abstract

The present invention relates to a polyporous round head catheter puncture needle, particularly to a medical puncture needle, which is suitable for washing hypertensive cerebral hemorrhage, traumatic cerebral hemorrhage, subacute and chronic subdural or extradural blood vessel, etc. The present invention is composed of a round needle head, a blunt outer catheter, a sharp outer catheter needle, a solid needle core and an adjustable double-groove-shaped skull bone gimlet, wherein the round needle head is provided with a plurality of suction holes; the blunt outer catheter is sheathed outside the puncture needle; the adjustable double-groove-shaped skull bone gimlet is matched with the puncture needle. The present invention has the advantages of small wound, few complications, thick tube diameter, multiple suction holes, small dead end, and high hematoma suction speed for 10 to 30 minutes. The catheter can be fixed in the brain, puncture does not need repeating, and the repeated trauma of brain tissues is reduced.

Description

Puncture probe with multi-porous bulb-headed catheter

The present invention is a kind of therapeutic medical puncture probe with multi-porous bulb-headed catheter, is applicable to hypertensive cerebral hemorrhage, injury-ness brain hemorrhage, and the flushing of subacute and chronic epidural hematoma, treatments such as brain abscess flushing, and the awl cranium is detected etc. under the field operations situation.

Present employed waist puncture needle of some hospitals of China or the sharp property of employing tubule footpath single hole syringe needle, its shortcoming is: damage cerebral blood vessel easily, because caliber carefully is difficult for extracting out hematoma, need to inject urokinase, easily form negative pressure, the suction intracerebral hematoma has certain resistance, pin hole easily stops up, and owing to have only a little pin hole, cecum is big, and drawing hematoma speed is slow, long a couple of days even the week age of often needing of time, and suction is not thorough, makes some critical patients can not get timely treatment, adopts operation of opening cranium, dangerous big, disability rate height, mortality rate height, thalamic hemorrhage mortality rate almost 100%.

In order to overcome the above-mentioned shortcoming of the sharp property of existing tubule footpath single hole puncture needle, the invention provides that a kind of cecum is little, the swollen speed of blood drawing is fast, suction thoroughly, no wound, puncture probe with multi-porous bulb-headed catheter that caliber is big.

The multi-porous bulb-headed catheter pricker comprises: puncture probe with multi-porous bulb-headed catheter body (see figure 1), the entity nook closing member (see figure 2) of this puncture needle, the sharp property outer catheter pin (Fig. 3) of this puncture needle and adjustable dual-trench type skull bone awl (Fig. 4).The caliber of the needle body of puncture probe with multi-porous bulb-headed catheter (3) is φ about 3, in the end of needle body (3) circular syringe needle (1) is arranged, on the tube wall of syringe needle (1) part, there are several bottoms of inhaling hole (2) needle body (3) that needle body handle (6) is arranged, on needle body (3), be with passivity outer catheter (4), cause the cerebral tissue repeated trauma when preventing repeated puncture, the about φ about 3.5 of its caliber, conduit handle (5) is arranged at its bottom; An entity nook closing member (7) is housed in needle body (3), is used for conducting puncture needle tubing and inhales hole (2) preventing to stop up; The sharp property outer catheter pin (Fig. 3) that is used with this puncture needle, it is used to puncture cerebral dura mater by the bone hole, the caliber of sharp property outer catheter pin also is φ about 3.5, sharp property syringe needle (9) is arranged at top, needle handle (10) is arranged at the bottom, and this puncture needle is used also has adjustable dual-trench type skull bone awl, and it comprises dual-trench type cone (13), about this cone or front and back corresponding grooves (15), it can add F.F. cranium speed, and the bone foam to going out, is reduced subcutaneous foreign body stimulation, protect from infection, because taper hole is big, puncture needle is at the intracranial adjustable angle, and suction face is big, on this cone (13), be with adjustable relief valve, rotate this valve, regulate into the cranium degree of depth, T font crossbeam taper shank (11) is arranged in this cone (13) upper end by its female thread, one end of taper shank (11) is to revolve jackscrew, is used for fixing cone (13).

Above-mentioned each parts can be made of rustless steel and other metal material.

Use operating instruction: 1. with multi-porous bulb-headed piercing needle, the entity nook closing member, passivity outer catheter pin, adjustable dual-trench type skull bone awl carries out autoclaving or boils after 40 minutes stand-by; 2. in patient's head location, carry out routine disinfection, do local anesthesia, cut 5 millimeters of skins,, after has bored in the bone hole, take off the bone awl with dual-trench type skull bone awl awl cranium; 3. the entity nook closing member is inserted in the multi-porous bulb-headed puncture needle, put sharp property outer catheter pin, make it, behind sharp property outer catheter punctures cerebral dura mater by the bone hole, take off sharp property outer catheter syringe needle, change the passivity outer catheter, import drawing hematoma or clot in the haematoma cavity, in aspiration procedure as run into needle tubing or inhale hole plug, the conducting of available entity nook closing member, accelerate pumping velocity, suction finishes, and takes off multi-porous bulb-headed piercing needle.

Description of drawings: Fig. 1 is multi-porous bulb-headed puncture needle body;

Fig. 2 is the entity nook closing member of this puncture needle;

Fig. 3 is the sharp property of this a puncture needle outer catheter pin;

Fig. 4 is adjustable dual-trench type skull bone awl.

Mark among the figure: (1) circular syringe needle, (2) inhale hole, (3) needle body, (4) sharp property outer catheter, (5) conduit handle, (6) needle body handle, (7) entity nook closing member, (8) needle core handle, (9) sharp property outer catheter syringe needle, (10) needle handle, (11) taper shank, (12) rotatable jackscrew, (13) dual-trench type cone, (14) adjustable safety valve, (15) corresponding groove.

The present invention compared with the prior art its advantage is:

1. adopt circular syringe needle wound little or do not have wound, complication is few;

2. sharp property outer catheter can be fixed in the brain, without repeated puncture, reduce the brain tissue repeated trauma;

4. this puncture needle is with outer catheter wherein has air to exist, and can prevent to produce negative pressure in the aspiration procedure, so need not inject any solvent medicine, can aspirate out each phase hematoma, shortens and treats the course of treatment;

5. use adjustable dual-trench type skull bone awl, awl cranium speed is fast, can reduce subcutaneous foreign body stimulation with the bone foam to going out, and protects from infection; Taper hole is big, makes puncture needle at the intracranial adjustable angle, and suction face is big;

6. the postoperative patient consciousness recovery is fast, and limb function is good, and disability rate is low;

7. operation does not need specific condition, does not even use special operating room, can carry out hands under local anaesthesia and state, and is particularly useful for boring under the field operations situation cranium and detects and rescue;

8. be applicable to hypertensive cerebral hemorrhage, injury-ness brain hemorrhage, under the subacute and chronic dura mater, the epidural hematoma flushing, treatment also can be done subcutaneous drainage tube and move under water, each position ventricles of the brain taper hole drainage, intracranial tumor aspiration biopsy;

9. curative effect is obvious, show through clinic trial, and treatment cerebral hemorrhage 242 routine cure rates 82.64%, mortality rate 17.36% is comprising 52 routine thalamic hemorrhages, cure rate 80%, mortality rate 20%; The treatment dura mater reaches epidural hematoma 34 examples, cure rate 100% down.
