Abstract
The utility model discloses a kind of puncture needle for ultrasound guidance, including puncture needle body and needle stand, needle stand is arranged on the tail end of puncture needle body, and needle stand connects with puncture needle body；The outer wall of described puncture needle body front end is provided with some grooves, and groove is along the length direction of puncture needle body and circumferencial direction array distribution.By the way, this utility model can provide more echo to probe, so that puncture needle can clearly be developed to picture.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of puncture needle for ultrasound guidance.
Background technology
Ultrasound guidance nerve block technique is that puncture needle is worn by anaesthetist under the guiding of high frequency portable ultraphonic
Lunge and arrive target nerve region into human body, around target nerve, complete injection site anaesthetic, produce satisfied anesthesia
The anesthesia of effect.This kind of technology has puncture safety, registration, minimizing damage, reduces sending out of anesthesia related complication
Raw rate, significantly improve the advantages such as nerve block success rate, the most extensively apply.Its concrete operations mode is: Anesthesia Department
The difference of physician in view site of puncture, makes patient keep suitable position, first site of puncture sterilization paving hole towel, then by adjusting height
Frequently linear array probe position, makes target nerve show image the most clearly on the ultrasound image, and it is constant then to fix probe positions, wears
Thorn point local anesthesia, uses method of needle insertion in plane, inserts puncture needle along ultrasonic probe outboard end, make the major axis of puncture needle and probe
Keeping parallelism direction inserting needle, on the ultrasound image Real Time Observation puncture needle inserting needle path, it was observed that needle point arrives target nerve district
Behind territory, around target nerve, complete injection site anaesthetic.
But, want Real Time Observation to may often be such that difficulty to puncture needle image clearly in ultrasonic field.Due to these god
All specular reflector through blockage puncture pin, and have that the inserting needle direction of puncture needle is less than normal with acoustic beam angle, puncture needle and spy
The reasons such as major axis is not parallel of head, cause sound wave to be reflected into internal at it rather than providing strong echo to probe.Result
Make puncture needle present breakage or fuzzy image in ultrasonoscopy, even do not observe a bit puncture needle image.Fiber crops
Liquor-saturated section doctor in operation, does not observes puncture needle and target nerve image clearly, can by repeatedly adjust probe and
Puncture needle position, seeks image effect clearly.So, not only lose time, also increase penetration damage and complication；If it is numb
Liquor-saturated doctor inadequate injection site anaesthetic, also can make anaesthetic effect have a greatly reduced quality, lose the excellent of ultrasound guidance nerve block
Gesture.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of puncture needle for ultrasound guidance, it is possible to spy
Head provides more echo, so that puncture needle can clearly be developed to picture, it is to avoid puncture needle is knitted with surrounding group nerve
Confused, puncture needle can be accurately positioned and guide operator accurately to be sent to by puncture needle needle point to target nerve region, shortening
The puncture procedure time, reduce the damage that repeated localised puncture increases to patient, reduce the incidence rate of complication, effective raising nerve resistance
Stagnant success rate；Its simple in construction, easy to use.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide one to draw for ultrasonic
Puncture needle under leading, including puncture needle body and needle stand, needle stand is arranged on the tail end of puncture needle body, needle stand and puncture needle body
Connection；The outer wall of described puncture needle body front end is provided with some grooves, and groove is along the length direction of puncture needle body and circumference
Direction array distribution.
Preferably, a length of 80mm of described puncture needle body, the external diameter of puncture needle body is 0.9mm, puncture needle body
Internal diameter be 0.3mm, in the range of described groove is distributed in the 30mm of puncture needle body front end.
Preferably, described groove is circular groove, and the opening diameter of circular groove is 0.25mm, and the degree of depth of circular groove is
0.15mm, the circular groove on puncture needle body length direction is spaced 0.45mm between any two, on puncture needle body circumferencial direction
Circular groove be spaced 0.45mm between any two.
Preferably, the outer wall of described puncture needle body indicates the scale on length direction, the top end face of puncture needle body with
Taper off to a point between the outer wall of puncture needle body cutting edge.
Preferably, described puncture needle body uses stainless steel material, and described needle stand uses transparent plastic.
The beneficial effects of the utility model are: this utility model can provide more echo to probe, so that wearing
Pricker can clearly be developed to picture.
Accompanying drawing explanation
Fig. 1 is that a kind of broken section structure for puncture needle one preferred embodiment of ultrasound guidance of this utility model is shown
It is intended to.
In accompanying drawing, the labelling of each parts is as follows: 1, puncture needle body；2, needle stand；3, circular groove.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define.
Referring to Fig. 1, this utility model embodiment includes:
A kind of puncture needle for ultrasound guidance, including puncture needle body 1 and needle stand 2, needle stand 2 is arranged on puncture needle originally
The tail end of body 1, needle stand 2 connects with puncture needle body 1；The outer wall of described puncture needle body 1 front end is provided with some circular grooves
3, circular groove 3 is along the length direction of puncture needle body 1 and circumferencial direction array distribution；Described puncture needle body 1 a length of
80mm, the external diameter of puncture needle body 1 is 0.9mm, and the internal diameter of puncture needle body 1 is 0.3mm；Described circular groove 3 is distributed in be worn
In the range of the 30mm of pricker body 1 front end；The opening diameter of circular groove 3 is 0.25mm, and the degree of depth of circular groove 3 is
0.15mm, the circular groove 3 on puncture needle body 1 length direction is spaced 0.45mm, puncture needle body 1 circumferencial direction between any two
On circular groove 3 be spaced 0.45mm between any two；Incident sound wave can be presented the diffuse reflector of resonance signal, to spy
