Description
Technical field
The utility model relates to a kind of brachial plexus nerve block needle guard parts of ultrasound guidance.
Background technique
Currently used nerve stimulation retardance needle is broadly divided into two kinds:
First is that external target needle, that is, inclined-plane needle (needle point is the acute angle less than 20 degree), disadvantage easily cause neural blood vessel cutting damage
Wound when external target needle is walked within the organization, be easy to cause more unnecessary damages, such as the cutting organized, punctures blood vessel (artery
It is easy to appear hemotoncus, vein is easy to appear extravasated blood), puncturing or cut nerve will lead to the corresponding domination area's skin fiber crops of light then nerve
It is powerless that wood, weight then accordingly dominate muscle；
Second is that interior its disadvantage of core needle, that is, side-hole needle (needle point is circle thorn type needle point) is more troublesome in skin penetrating process, puncture
Power is big, and patient pain is big, meanwhile, during puncture, in order to avoid causing possible damage to nerve and blood vessel, as far as possible
The lesser needle tubing of outer diameter is compared in selection.Since needle body is thinner, when carrying out deep face puncture, needle body is easy with muscle et al.
The movement of body tissue and deform, cause needle point to shift so that needle point and nerve distance generate deviation.
When operation due to epitheca needle not really reach target nerve attachment, when by epitheca needle set stay pipe when, set
Pipe position inaccuracy, it cannot be guaranteed that continuous block effect.
Utility model content
In order to solve the above-mentioned technical problem the utility model provides a kind of brachial plexus nerve block needle guard of ultrasound guidance
Part significantly reduces the puncture pain of patient, and it is accurate to set pipe, is able to achieve continuous block effect.
To achieve the above object, the utility model uses following technical scheme:
A kind of brachial plexus nerve block needle guard part of ultrasound guidance, it includes epitheca needle, the epitheca needle needle heart, interior core needle, sets
It stays pipe and sets and stay tube connector, which matches with the epitheca needle, when the epitheca needle needle heart plug-in card is in the epitheca needle,
The head of the epitheca needle needle heart is concordant with the syringe needle of the epitheca needle, this is set on the needle body for staying pipe sleeve to be located at the interior core needle, the inner core
The side opening of needle to needle point position, which exposes to this, sets and stays pipe, stays the interior core needle plug-in card of pipe in the epitheca needle when being arranged with this and setting,
This sets the syringe needle for staying the tail end of pipe to stretch out the epitheca needle, this, which is set, stays tube connector to set with this pipe is stayed to match.
The epitheca needle is inclined-plane bodkin, which includes bodkin body, and the tail end of the bodkin body is inserted admittedly in handle portion, should
Handle portion offers the duct being connected to the through-hole of the bodkin body, and the handle portion of the epitheca needle separately opens up one for pressing described set
It stays the press section of pipe tail end or opens up an opening in the handle portion of the epitheca needle, which sets the tail portion pair for staying pipe with described
It answers.
The press section is the transparent elastomer that the epitheca needle handle portion is arranged in.
The interior core needle is side opening fine needle, which includes fine needle body, which inserts solid in handle portion, the handle portion
Offer the duct being connected to the vestibule of the fine needle body.
The handle portion of the handle portion of the epitheca needle and the interior core needle is connected structure.
The handle portion of the epitheca needle is equipped with a slot, and it is matched with the slot to be equipped with one in the handle portion of the interior core needle
Protrusion.
The epitheca needle needle pericardium includes tube body and grip part, tube body head end closing, and the aft end of the tube body is inserted to exist admittedly
The grip part, the head of the tube body block the syringe needle of the epitheca needle, and the two is in concordant shape, the gripping of the epitheca needle needle heart
Portion is equipped with the matched inserted sheet of the slot with the epitheca needle.
Described set stays pipe also to match a fixator.
The utility model has the beneficial effects that passing through ultrasound with being punctured after external target needle and the combination of the external target needle needle heart first
Needle point is rested on neural 2 centimeters of distance by observation, and due to being beveled point, puncture force is small, and patient's pain is small, can build rapidly
Vertical puncture channel, and because farther out apart from nerve distance, injuring nerve and blood vessel can be prevented.The external target needle needle heart is extracted, then is used
Interior core needle is penetrated out of external target needle needle tubing, can obviously and outside under ultrasound since interior core needle leading portion is designed with ultrasonic development
The needle body of needle distinguishes, and then proceedes to deeply, carry out nerve stimulation retardance operation.Under the cooperation of ultrasound, interior core needle is guided to connect
Nearly nerve, and needle point is moved in target area, the side opening needle point designs of interior core needle can be effectively prevented to nerve and blood vessel
Carry out cutting damage；Pipe is stayed in the set setting of interior core needle, after puncturing administration, can directly and accurately set and stay near target nerve,
Guarantee subsequent lasting blockage effect；Compared with tradition sets and stays pipe, the utility model is set than tradition stays pipe to be exposed to outside skin
It is short very much, the case where being not in discounting, stays pipe skin is external so that be not in re-replace to set the problem of staying pipe
It stays tube connector setting so far to stay pipe outer wall that one fixator is set with setting, is fixed on the skin with medical proof fabric on the holder,
Prevent indwelling tube from shifting.
