Abstract
The present invention provides a kind of puncture needle butterfly wing structures, belong to medical equipment technical field.It solves the problems, such as that existing butterfly wing structure is simple so that puncture success rate can not be significantly improved.This puncture needle butterfly wing structure, including columned installation set and two wing bodies being arranged on the peripheral surface of installation set, one end of two wing bodies is both connected to the same position on installation set peripheral surface, wing body has one end interconnecting piece flexible being connected on the peripheral surface of installation set and the clamping part being connect with the interconnecting piece other end, the thickness of clamping part is more than the thickness of interconnecting piece, the outer surface of clamping part is the rubbing surface being serrated, wherein the inner surface of a clamping part outer end has positioning convex strip, the inner surface of another clamping part outer end has the locating slot that can be interlocked with positioning convex strip.The butterfly wing of this structure is not susceptible to skid, and improves the accuracy that the angle of inserting needle is held, error is smaller, significantly improves puncture success rate.
Description
Technical field
The invention belongs to medical equipment technical fields, are related to a kind of butterfly wing, especially a kind of puncture needle butterfly wing knot
Structure.
Background technology
Currently, puncture needle is a kind of common medical equipment, existing common moral puncture needle has generally comprised hose, has been fixed on
The draw point of hose one end and the butterfly wing being set on hose, the structure of traditional butterfly wing is simple, although can facilitate medical matters
Personnel's inserting needle, but since traditional butterfly wing is not very ideal the effect that grips of hose, easily occur in inserting needle
Slipping phenomenon causes the angle of inserting needle to be held inaccurate, and error is larger, and puncture success rate, which has no, to be significantly improved.
Invention content
The purpose of the present invention is there is the above problem in view of the prior art, it is proposed that a kind of puncture needle butterfly wing knot
Structure, the technical problem to be solved by the present invention is to：How the puncture success rate of puncture needle is improved.
Object of the invention can be realized by the following technical scheme：A kind of puncture needle butterfly wing structure, including cylinder
The installation set of shape and two wing bodies being arranged on the peripheral surface of installation set, which is characterized in that one end of two wing body connects
The same position being connected on installation set peripheral surface, it is flexible on the peripheral surface of installation set that there is the wing body one end to be connected to
Interconnecting piece and the clamping part being connect with the interconnecting piece other end, the thickness of the clamping part are more than the thickness of interconnecting piece, the folder
The outer surface for holding portion is the rubbing surface being serrated, wherein the inner surface of a clamping part outer end has positioning convex strip, another clamping
The inner surface of portion outer end has the locating slot that can be interlocked with positioning convex strip.
This butterfly wing is mounted on the hose of puncture needle and uses, in use, two wing bodies are relatively rotated so that two wings
The outer end of body leans, at this point, since interconnecting piece is flexible, two interconnecting pieces wrap the half of hose peripheral surface, and one
Positioning convex strip on clamping part is embedded in the locating slot on another clamping part so that two clamping parts cannot occur to slide relatively
It is dynamic, ensure that the relative position of two clamping parts is fixed, the rubbing surface on clamping part improves and clamping workpiece or medical worker's hand
The frictional force of finger so that the entire butterfly wing is not susceptible to skid in piercing process, improves the accurate of the angle assurance of inserting needle
Property, error is smaller, significantly improves puncture success rate.
In a kind of above-mentioned puncture needle in butterfly wing structure, the inner surface of the clamping part and the inner surface of interconnecting piece it
Between have inclined surface.For the structure when two interconnecting pieces wrap the half of hose peripheral surface, which is resisted against hose
On peripheral surface, i.e. the inner end of clamping part is resisted against on the peripheral surface of hose so that two clamping parts form triangular structure, improve
Clamping stability.
In a kind of above-mentioned puncture needle in butterfly wing structure, the trapezoidal structure of the clamping part.
In a kind of above-mentioned puncture needle in butterfly wing structure, the thickness of the interconnecting piece is 1-2mm.
In a kind of above-mentioned puncture needle in butterfly wing structure, the thickness of the clamping part is 3-4mm.
Compared with prior art, puncture needle of the invention is had the following advantages with butterfly wing structure：Two interconnecting pieces are by hose
The half of peripheral surface wraps, and the positioning convex strip on a clamping part is embedded in the locating slot on another clamping part so that two
Clamping part cannot occur it is opposite slide, ensure that the relative position of two clamping parts is fixed, the rubbing surface on clamping part improve with
The frictional force of clamping workpiece or medical worker's finger so that the entire butterfly wing is not susceptible to skid in piercing process, improves
The accuracy that the angle of inserting needle is held, error is smaller, significantly improves puncture success rate.
