Abstract
The utility model discloses an abscess puncture drainage needle. The abscess puncture drainage needle comprises a needle core and a sleeve, wherein the needle core is inserted inside the sleeve, the tip of the needle core extends out of the front end of the sleeve, the front end of the sleeve is provided with a blade, both sides of the blade are edged, and the blade can be a flat blade or an arc-surface blade. After the abscess puncture drainage needle punctures an abscess, the multiple abscess walls of the abscess can be cut open by operating the blade at the front end of the sleeve instead of inserting the needle tip into the sleeve again, so that thorough drainage for the complex abscess can be obtained simply through one puncture; the blade cannot affect the matched insertion of the existing needle core and the sleeve. The abscess puncture drainage needle achieves improvement on the basis of an existing drainage needle and is simple in operation, few in injuries to a patient, low in degree of pain and good in abscess drainage effects.
Description
Technical field
This utility model belongs to medical apparatus and instruments, is specifically related to a kind of abscess puncture drainage needle for abscess evacuation of pus in body.
Background technology
Abscess is in actute infection process, and in tissue, organ or body cavity, the limitation pus occurring because of pathological changes tissue necrosis, liquefaction gathers, and surrounding has a complete pus wall.The means of its clinical treatment normally puncture the pus wall of abscess by its inner pus drain out.Take mammary abscess as example, first under hyperacoustic detection, find abscess accurately and be positioned at subcutaneous position, by the drainage needle skin corium that punctures, enter after puncturing pus wall in body inner pus is drawn, drainage needle is a kind of hollow sleeve pipe, by puncturing after abscess, inner pus is drained to external from sleeve pipe.But often can run into clinically the abscess case of more complicated; while having multilamellar or a plurality of abscess to be sticked together as pus wall; current drainage needle can only puncture one by one pus wall and carry out drain; deal with cumbersome; even may need repeatedly to puncture; doctor operates cumbersome, brings larger misery to sufferer simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of abscess puncture drainage needle for the above-mentioned defect of current abscess puncture drainage existence, and it realizes effective drainage for comparatively complicated abscess by one-time puncture, and doctor is easy to operate, and sufferer pain is little.
This utility model adopts following technical scheme to realize: abscess puncture drainage needle, comprise nook closing member 1 and sleeve pipe 2, and described nook closing member 1 is inserted in sleeve pipe 1, and its needle point stretches out described sleeve pipe front end, and described sleeve pipe 2 front ends are provided with blade 21.
Further, blade is offered in described blade 21 both sides.
As a kind of preferred version of the present utility model, described blade 21 is plane blade, and the cambered surface of its place plane and described sleeve pipe 1 is tangent.
Further, the plane blade that described blade 21 is isosceles triangle, two hypotenuses of described blade 21 are offered blade, and the length on base is less than the external diameter of described sleeve pipe 2.
As another kind of preferred version of the present utility model, described blade 21 is cambered surface blade, and its cambered surface is the partial arc face that extend described sleeve pipe 1 tube wall end.
Further, the cambered surface both sides of described blade 21 have rectilinear edge.
Or the cambered surface both sides of described blade 21 have curved blade, the top intersection of described curved blade forms point of a knife or transition arc blade.
In this utility model, one section of tube wall of described sleeve pipe 2 front ends is provided with some conduction holes 22, increases the efficiency of pus drain.Described sleeve pipe 2 rear ends are provided with for connecting the flow sub 23 of negative pressure straw, and described flow sub 23 is greater than the tubular configured joint of sleeve pipe 2 for diameter.The afterbody of described nook closing member 1 is provided with nook closing member base 11, the diameter of described nook closing member base 11 is greater than the internal diameter of described flow sub 23, when nook closing member is inserted into inside pipe casing like this, nook closing member base can be against the end face location nook closing member of flow sub, and assurance nook closing member can be extracted out smoothly after puncture abscess in sleeve pipe.
During concrete operations of the present utility model, first casing pipe sleeve is contained on nook closing member, the tip portion of nook closing member is stretched out sleeve pipe, then nook closing member and sleeve pipe are together punctured, the needle point of nook closing member punctures the pus wall of abscess, then nook closing member is extracted out from sleeve pipe, the flow sub of sleeve pipe rear end is connected to negative pressure straw, by negative pressure by pus quick drainage out.While having multiple pus wall as abscess, can by handling the blade cuts of sleeve pipe front end, break the pus wall of both sides, without needle point is injected in sleeve pipe again, one-time puncture can carry out drain thoroughly by complicated abscess.The setting of blade can not have influence on the insertion coordinating of original nook closing member and sleeve pipe.
From the above mentioned, this utility model improves on the basis of existing drainage needle, simple to operate, and the wound of sufferer is few, distress level is little, and abscess drainage effect is good.
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
