Description

A kind of area CPA artitificial ear brain glue injection needle

Technical field

The utility model relates to medical instruments, and in particular to injecting glue needle used in a kind of art.

Background technique

Trigeminal neuralgia is the most common cranial nerve disease, with the battle array of recurrent exerbation in the face trigeminal neuralgia distributed area of side Hair property is bitterly acutely main performance.It is as follows for the microvascular decompression substantially process of trigeminal neuralgia: in Ipsilateral ear under general anesthesia Afterwards, in hairline 4~5cm of stringer straight cut, skull opens the hole diameter about 2cm, cerebellopontine angle region is entered under microscope, to trident Neural traveling area is detected, and there may be the blood vessel of compressing, arachnoid bar ropes all to peel away with nerve by all, and by these Blood vessel is isolated with Tefflon gasket with nerve root, once compressing vessels are isolated, the root for generating stimulation disappears, trident mind High excitability through core will disappear therewith, restore normal.Most patient's postoperative pains disappear immediately, and retain normal Facial perception and function, do not influence quality of life.Higher requirement is placed with for Tefflon gasket in the above process, is caused Operating process is more time-consuming and laborious.

It has been reported that and blood vessel is isolated using ear brain glue, ear brain glue has certain fluidity between solid and liquid, passes through note Glue process can Fast Filling in target location, block vascular compression nerve, reach same operation purpose.But current ear brain glue Injection generally use puncture needle, puncture needle has sharp head, is easy to puncture blood vessel, causes unexpected injury, and injecting glue position It sets and is difficult to control accurately, influence surgical effect.

Summary of the invention

The purpose of this utility model is to provide a kind of area CPA artitificial ear brain glue injection needles.

In order to achieve the above objectives, the utility model uses following technical scheme:

Preferably, injecting glue lever is provided on the attachment base.

Preferably, it is provided with the light source around the attachment base on the injecting glue lever, the direction of illumination of light source is towards institute State closed end.

Preferably, the light source uses LED, small in size, convenient for arrangement, good illumination effect.

Preferably, the injection needle further includes snap ring, and the injecting glue lever is ring-type, the inner ring and bullet of injecting glue lever Property snap ring outer ring be connected, the attachment base is connected with the inner ring of snap ring.

Preferably, the snap ring is made of silica gel or rubber.

Preferably, the plastic emitting side hole is ellipse, is more advantageous to and fast and accurately completes injecting glue.

The beneficial effects of the utility model are embodied in:

The utility model avoids during injecting glue by using the needle tubing with concordant end and punctures blood vessel equivalent damage The problem of tissue, in conjunction with set plastic emitting side hole, it is ensured that the ear brain glue for being passed through needle tubing can accurately inject blocked goal Position forms good retarding construction, ensure that surgical effect, significantly reduces the generation of unexpected injury in operation.

Specific embodiment

The utility model is described in further details with reference to the accompanying drawings and examples.

Referring to Fig. 1 and Fig. 2, artitificial ear brain glue injection needle in the area CPA described in the utility model includes attachment base 3 and fixes Needle tubing 2 on attachment base 3,2 hollow space of needle tubing are glue injection channel 4, and one end of needle tubing 2 is defeated by attachment base 3 and ear brain glue Enter end (the ear brain glue power transmission pipeline at operating room scene or with the preprepared hand gun for storing ear brain glue Tool) connection, the other end closing of needle tubing 2, and there is concordant end, by using such concordant end, i.e., for existing Insertion type needle construction (such as puncture needle) head has carried out Passivation Treatment, avoids damage to tissue (such as blood vessel, nerve etc.). The plastic emitting side hole 1 being connected to glue injection channel 4 is opened up in 2 side wall of needle tubing, it can be with to flow to the ear brain glue of the concordant end of needle tubing It smoothly is injected into blocked goal position, and can accurately adjust injection phase.

Referring to fig. 2, in order to complete injecting glue under lesser needle tubing diameter, so that injecting glue position precision is improved, it is described 3 interior design of attachment base is the glue chamber 5 (i.e. funnel channel) being connected to glue injection channel 4, thus when ear brain glue enters attachment base 3 Afterwards, accelerated by being gradually reduced the channel of caliber, and can smoothly enter into glue injection channel 4, complete injecting glue, avoid glue injection channel 4 because Needle tubing diameter reduces and occurs to flow backwards spilling.

The needle tubing 2 and attachment base 3 are made of medical metal material, are had some strength, are guaranteed that it can be accurate Ear brain glue is conveyed to blocked goal position, the size of recommendation is as follows: needle tubing pipe range is about 8cm, and bore is about 1mm, pipe outside diameter About 2.5mm, plastic emitting side hole (elliptical aperture) major diameter is about 1.5mm, and minor axis is about 0.5mm.

Injecting glue effect is improved, injecting glue lever is provided on attachment base 3 in order to optimize injecting glue operation referring to Fig. 3 and Fig. 4 6, injecting glue lever 6 is ring-type, is provided with LED light source 7 on injecting glue lever 6, around attachment base 3 on the outside of be disposed with multiple shine Location point provides brighter visual area for injecting glue process, and moves synchronously with the holding of injecting glue position adjustment, provides trailing type Illumination significantly compensates for the adjustment flexibility difference and the limited deficiency of adjustment angle of operation shadowless lamp, head mounted lamp.Injecting glue is held Handle 6 is made of engineering plastics, and engineering plastics are easy to form and design internal cavity structure, so that injecting glue lever 6 exists More meet in shape ergonomics (for example, by using the shape for symmetrically cutting circular contour part), it is internal then provide compact-sized The space arranged for control circuit for light source and power supply.

The injecting glue needle first positions injecting glue position when in use, using the needle tubing 2 with attachment base 3, then by attachment base 3 It is docked with ear brain glue input terminal, the disturbance for syringe location is inevitably generated in docking operation and is even changed, for this purpose, being held in injecting glue Coaxial mounted snap ring 8 (silica gel or rubber production) is arranged in 6 inner ring of handle, both can be convenient attachment base 3 and has passed axially through note 6 inner ring of glue lever, and attachment base 3 is adaptively clamped, and the percussion in docking operation can be absorbed, make operator The injecting glue position of needle tubing 2 can be easily kept and steadily holding injecting glue lever 6.
