Description
Technical field
The present invention relates to medical appurtenance field, especially Nephrology dept.'s fixing apparatus for puncture needle.
Background technology
When puncture for treating is performed the operation in kidney at present, operative doctor can only rely on personal experience's progress lancet puncture and be mostly
Patient is performed the operation, and when renal puncture is performed the operation, puncture needle is usually required with certain bevel angle inserting needle, follow-up to facilitate
Detection device is scanned and monitored；Especially in surgical procedure, the stability of strict guarantee piercing needle fixation, is prevented
The unexpected injury caused by syringe needle slides, although having some auxiliary stabilizers at present to aid in the fixation of puncture needle, makes mostly
With ineffective, do not simply fail to effectively bring convenience to operation, can also bring certain uncertainty to operation on the contrary, make trouble
Person leaves certain postoperative risk after surgery.
The content of the invention
For the situation of prior art, it is an object of the invention to provide a kind of easy to operation, fixed reliable and can be square
Just Nephrology dept.'s fixing apparatus for puncture needle of puncture needle penetration depth is adjusted.
In order to realize above-mentioned technical purpose, the technical scheme is that：
Nephrology dept.'s fixing apparatus for puncture needle, it includes being used to position the positioning seat of patient's puncture position and for adjusting puncture needle
The banking stop of depth is pierced into, the upper surface center of the positioning seat has a tubular lug boss, the center of the tubular lug boss
With inner fovea part, the bottom centre of the inner fovea part is provided with through the hole of threading a needle of positioning seat lower surface, the tubular lug boss
Upper end both sides are provided with stopper slot that is recessed and merging the limitation banking stop anglec of rotation for matching somebody with somebody with banking stop, described banking stop bag
Include and be detachably connected the first banking stop of ground and the second banking stop, the middle part of first banking stop is provided with the first of semicircular structure
Curved portions, the middle part of second banking stop is provided with to be adapted and is engaged with the first curved portions to be formed with the first curved portions structure
Second curved portions of cirque structure, attach on the medial surface of first curved portions and the second curved portions be fixed with it is fan-shaped even
Contact pin, when puncture needle be placed between the first curved portions and the fan-shaped connection sheet of the second curved portions and respectively with fan-shaped connection sheet
When side is affixed, by the way that the first banking stop and the second banking stop are interfixed, fixation of the banking stop on puncture needle, institute are realized
The puncture needle stated through positioning seat thread a needle hole when, offseted by the lower surface of banking stop and the bottom of stopper slot, realize puncture needle
It is pierced into the constraint of depth.
Further, the lower surface edge of the positioning seat, which rotates, is fixed with least two for being attached on skin and will determine
The fixed strip that position seat is fixed, one end of the fixed strip, which rotates, to be fixed on positioning seat, and the other end of fixed strip extends outward
The end face of positioning seat, the fixed strip and skin contact is provided with adhesive layer.
Preferably, the lower surface of the positioning seat correspond to fixed strip rotation fixed position be provided with concave configuration and it is described under
The recessed structure both sides adjacent with positioning seat edge are used for the rotational angle for limiting fixed strip.
Preferably, described fixed strip is integrally formed for flexible material.
Further, the length direction both sides of first banking stop are equipped with connection bump, the length of second banking stop
Connection bump on corresponding first banking stop in degree direction both sides is provided with the connection through hole that structure is adapted and is engaged by clamping with it.
Further, when first banking stop and the second banking stop and stopper slot coordinate, the first banking stop and second spacing
The horizontal both ends of piece exceed the outward flange of stopper slot.
Further, described fan-shaped connection sheet is integrally formed for silicon rubber.
Further, the tubular lug boss on the positioning seat vertical direction projection positioned at positioning seat drop shadow spread it
It is interior.
Further, described positioning seat, the first banking stop and the second banking stop are that plastic material is integrally formed.
Further, the lateral cross section of the positioning seat is shaped as circle.
Using above-mentioned technical scheme, beneficial effects of the present invention are：By setting positioning seat to need what is punctured with patient
Skin site is affixed, the skin site face that the hole site of threading a needle of positioning seat need to be only pierced into by medical personnel with patient's needs, so
Fixed fixed strip is rotated by positioning seat lower surface afterwards to fix with skin attachment, you can the preliminary determination for completing operative site,
In addition, the depth that medical personnel can be pierced into puncture needle as needed needs reserved wear to combine the height of positioning seat and calculate
Pricker working length, then the first banking stop and the second banking stop are interfixed in the correspondence position of puncture needle, make
The medial surface of fan-shaped connection sheet on one banking stop and the second banking stop is close to the side of puncture needle, and banking stop is fixed on
On puncture needle, now carrying out puncture procedure only need to be relative with the stopper slot of positioning seat by the horizontal both ends of banking stop, then will wear
Pricker is progressively pierced into patient skin from hole of threading a needle, and when the lower end of last banking stop offsets with spacing trench bottom, puncture needle pierces just
The depth entered is consistent with plan piercing depth, and now due to the effect of contraction of limited location groove so that banking stop is not in big
Amplitude is rocked or the situation of displacement, also allows medical personnel conveniently further to be operated, due to there is the first of positioning seat
Step positioning so that when carrying out puncture procedure, can more convenient ground assist personnel operate, substantially reduce medical personnel's
Puncture procedure difficulty, also the therapeutic effect for patient play Reliable guarantee, avoid follow-up occur puncturing sequelae as far as possible
Situation, further, since the first banking stop and the second banking stop is be engaged by clamping, if therefore needing to carry out in subsequent operation
Regulation, can facilitate and be dismantled, and then re-start position positioning, and on the first banking stop and the second banking stop
The structure of fan-shaped connection sheet can be adapted with puncture needle so that fan-shaped connection sheet can be entered from the puncture needle of different dimensions
Row coordinates, and improves the relevance grade of banking stop, and the fixed strip of positioning seat lower end is arranged to rotary form so that is carrying out
In use, fixed strip can be fixed in suitable skin site according to the position that the skin conditions and needs of patient puncture,
To be further ensured that the fixation reliability of positioning seat and positioning accuracy, it is set really to be able to accomplish to mitigate medical personnel's operation by force
The purpose of degree, and hygiene-type and anticorrosive property and cost are used in order to improve, by the first banking stop, the second banking stop and it can determine
Position seat is arranged to plastic material and is integrally formed, and light weight, the wholesomeness of one side plastic material are good, on the other hand can be easy into
Row processing, it is avoided as much as medicine equipment pollution.
