Description

A kind of blockage resisting twin flue puncture needle for nerve block reducing nerve injury

Technical field

This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of reduce nerve injury Blockage resisting twin flue nervous tissue puncture needle.

Background technology

Nerve block anesthesia is a kind of in nerve trunk, clump, the surrounding injection local anaesthetics of joint, retardance Its conduction of impulse, makes arranged region produce anesthesia, reaches painless method of performing the operation, and is working as Before have the most universal application clinically, between conventional nerve block helps, under socket of the eye, ischium, Refer to the retardance of (toe) nerve trunk, cervical plexus, brachial plexus block, and the starlike god of diagnosis and treatment Warp knuckle and lumbar sympathetic ganglion block etc..

Nerve block anesthesia needs use puncture needle for nerve block, for nerve trunk, clump, The surrounding injection local anaesthetics of joint, and with electrical stimulation device and impedance detection device, with exactly Place puncture needle, under less anesthesia consumption, obtain preferable nerve block effect.Current There is following defect in puncture needle for nerve block:

The most current needle tip end design is unreasonable, and it is smooth that the most blunt termination impact punctures Property, nerve is then easily caused damage by the sharpest keen termination；2. the boring of puncture needle, In piercing process the most blocked, cause medicinal liquid not pass through；3. puncture needle only has a medicine-pouring pipe, But in practical operation, need to inject medicinal liquid or saline in the different periods, thus need Changing different syringes, this process is inconvenient, and easily produces bubble in pipe, increases Infect probability.

Summary of the invention

For above-mentioned problems of the prior art, the purpose of this utility model is, it is provided that A kind of blockage resisting twin flue puncture needle for nerve block reducing nerve injury, overcomes prior art Present in problem, make puncture effect more preferable.

In figure, label represents: 1 nook closing member, 2 needle tubings, 3 bases, 4 wires, and 5 the One connects end, 6 first liquid injection pipes, 7 external screw threads, 8 plugs, and 9 second connect end, 10 second liquid injection pipes, 11 extension tubes, 12 female threads, 13 sealing-plugs, 14 projections, 15 end caps, 16 demarcation strips, 17 through holes.

Detailed description of the invention

Defer to technique scheme, as shown in Figures 1 to 4, a kind of reduce nerve injury Blockage resisting twin flue puncture needle for nerve block, including needle tubing 2, base 3 be arranged on base 3 On wire 4, needle tubing 2 is arranged on the front end of base 3；In the rear end of base 3 removably Be provided with nook closing member 1 and end cap 15, the front end of nook closing member 1 can pass from the rear end of base 3 base 3, Needle tubing 2 front end from needle tubing 2 are stretched out, and base 3 rear end can be sealed by end cap 15； The first liquid injection pipe 6 and the second liquid injection pipe 10, the first liquid injection pipe 6 is had connecting on the base 3 With the second liquid injection pipe 10 and needle tubing 2 company of passing through.

As it can be seen, agent structure of the present utility model is identical with existing puncture needle, all include Base 3 and the needle tubing 2 being arranged on base 3 front end, needle tubing 2 and leading of passing on base 3 Line 4 connects, and wire 4 is for carrying out electricity irritation by needle tubing 2, to strengthen nerve block effect； Difference is, puncture needle base 3 rear end of the present utility model is penetrating, from base 3 Rear end has been removably disposed nook closing member 1 and end cap 15.

Wherein, nook closing member 1 is used for assisting puncture, and nook closing member 1 front end is through base 3, needle tubing 2 also Stretching out from needle tubing 2 front end, nook closing member 1 front end is sharp-pointed, not inclined-plane, and is solid construction, this Sample is very beneficial for puncturing；After puncture completes, extract nook closing member 1 from base 3 rear end, and the end of to Seat 3 rear ends utilize end cap 15 to seal, then can pass through respectively the first liquid injection pipe 6, the Two liquid injection pipes 10 carry out the injection of anesthetics, saline；The two can carry out distinguishing simultaneously Carrying out, such injection process need not frequently change syringe, facilitates the injection of medicinal liquid, and Reduce infection probability.

Specifically, inside base 3, passage, described needle tubing the 2, first note axially it are provided with Liquid pipe the 6, second liquid injection pipe 10 passes through even by passage, and i.e. medicinal liquid, saline are from base 3 inside Passage flow to needle tubing 2.It is symmetrically arranged with on base 3 and passes through the even with base 3 inner passage One connects end 5 and second connects end 9, the effect of the two structure be to the first liquid injection pipe 6, Protection is played in the junction of the second liquid injection pipe 10, and bending makes fluid injection not to prevent junction from occurring Freely；First angle connecting end the 5, second connection end 9 axial with base 3 is acute angle, so Reduce as far as possible and connect the space that end takies, do not affect normal operating；The first described fluid injection Pipe 6 is connected end 5 with first and connects, and the second liquid injection pipe 10 is connected end 9 with second and connects.

In order to preferably use nook closing member 1 and end cap 15, the rear end of base 3 is coaxially arranged with prolongs The internal company of passing through of long tube 11, extension tube 11 and base 3；Described end cap 15 removably fills Fit in extension tube 11.Such as Fig. 1, end cap 15 is with female thread 12, outside extension tube 11 External screw thread 7 it is provided with on wall；End cap 15 is internally provided with projection 14, and projection 14 is provided with For sealing the sealing-plug 13 of extension tube 11.After nook closing member 1 uses, end cap 15 is detained In extension tube 11, then rotating end cap 15, extension tube 11 rear end can be sealed, Will not leakage at extension tube 11 during fluid injection.

As shown in Figure 4, the front end of nook closing member 1 is conical structure, and the rear end of nook closing member 1 is provided with Diameter is more than the plug 8 of extension tube 11, and the length of nook closing member 1 is more than needle tubing 2, base 3 and prolongs The length sum of long tube 11, so can ensure that nook closing member 1 front end can be stretched out from needle tubing 2 front end, Convenient puncture.As in figure 2 it is shown, center within base 3 is axially disposed demarcation strip 16, the length of demarcation strip 16 is less than the length of base 3；Described first connection end 5, the Two connect end 9 is connected on base 3 sidewall of demarcation strip 16 both sides.

The effect of demarcation strip 16 is that medicinal liquid, saline are carried out water conservancy diversion respectively, makes two kinds of liquid Do not interact after being injected in base 3, prevent that side pressure is excessive causes liquid from opposite side Diffuse out；Demarcation strip 16 only arranges one section, from the beginning of the rear end of base 3, not with base 3 Front end in contact, the medicinal liquid that two such liquid injection pipe injects is respectively by the sky of demarcation strip 16 both sides Between converge again to base 3 front end, enter back in needle tubing 2, do not interact.

Owing to being provided with demarcation strip 16, in order to not affect the use of nook closing member 1, in demarcation strip 16 The through hole 17 passed through for nook closing member 1 is offered vertically at the heart.As shown in Figure 4, in this programme Needle tubing 2 front end is ramp-like structures, but tiltedly degree of a face is less, is 15 °～about 30 °, The most also adjustable position, but owing to it is not sharp-pointed, so can avoid god largely Through causing damage.
