Abstract
This utility model embodiment provides a kind of percutaneous needle of applicable B ultrasonic location, for improving the development state of percutaneous needle under ultrasonic effect.The technical scheme of this utility model embodiment comprises: a kind of percutaneous needle of applicable B ultrasonic location, comprise stylophore and nook closing member, described nook closing member comprises needle point, nook closing member body, described needle point is placed on described stylophore, described nook closing member body comprises nook closing member body head end and non-nook closing member body head end, the described outer wall of nook closing member body head end and the inwall of described stylophore are fitted, and have space between the outer wall of described non-nook closing member body head end and the inwall of described stylophore.
Description
Technical field
This utility model embodiment relates to medical instruments field, particularly relates to a kind of percutaneous needle of applicable B ultrasonic location.
Background technology
Traditional percutaneous needle is made up of nook closing member body and stylophore portion, and nook closing member body is an elongated cylinder, and stylophore is oval tubular, and the nook closing member body protruding from stylophore head end is taper needle point, can play puncture effect.Nook closing member body is grown up cylindric, and like this after nook closing member body is inserted in stylophore, the inwall of nook closing member body and stylophore can be good at closing, and does not almost have gas to retain in it.When using this percutaneous needle to carry out human internal organ puncture, nook closing member body is inserted in stylophore, then puncture human body, punctures successfully, and nook closing member body can be extracted, let the acupuncture needle remain at a certain point, and sheath is motionless in original position, can insert seal wire etc. carry out next step operation technique through stylophore.
Surgical clinical percutaneous needle used is above-mentioned puncture needle, uses this puncture needle can guide or ultrasound guidance at X-ray examination, the specific internal organs of percutaneous puncture human body, punctures with percutaneous renal puncture and percutaneous transhepatic puncture as many.This puncture needle can be good at display under X-ray examination, can adopt x-ray guided puncture smoothly.
But when using ultrasound guided puncture, being then often difficult to show needle shadow effectively, needle tip and the puncture needle track of percutaneous needle can not be shown under many circumstances well.
Utility model content
This utility model embodiment provides a kind of percutaneous needle of applicable B ultrasonic location, for improving the development state of percutaneous needle under ultrasonic effect.
The technical scheme of this utility model embodiment comprises:
A kind of percutaneous needle of applicable B ultrasonic location, comprise stylophore and nook closing member, described nook closing member comprises needle point, nook closing member body, described needle point is placed on described stylophore, described nook closing member body comprises nook closing member body head end and non-nook closing member body head end, the described outer wall of nook closing member body head end and the inwall of described stylophore are fitted, and have space between the outer wall of described non-nook closing member body head end and the inwall of described stylophore.
Optionally,
Described stylophore, described nook closing member body head end are cylindrical, and the diameter of described stylophore and the diameter of described nook closing member body head end match, and the described outer wall of nook closing member body head end and the inwall of described stylophore are fitted.
Optionally,
Described non-nook closing member body head end is cylindrical.
Optionally,
Described nook closing member is formed in one.
The beneficial effect of this utility model embodiment is:
By fitting at the outer wall of nook closing member body head end and the inwall of stylophore, then between the outer wall of non-nook closing member body head end and the inwall of stylophore, there is space, to air, there is strong reflexive due to ultrasonic, the development state of percutaneous needle under ultrasonic effect of applicable B ultrasonic location of the present utility model can be improved.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
Fig. 1 is the stylophore structural representation of the percutaneous needle of a kind of applicable B ultrasonic location of this utility model embodiment;
Fig. 2 is the nook closing member structural representation of the percutaneous needle of a kind of applicable B ultrasonic location of this utility model embodiment;
Fig. 3 is the scheme of installation of the percutaneous needle of a kind of applicable B ultrasonic location of this utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1 to Fig. 3, this utility model embodiment provides a kind of percutaneous needle of applicable B ultrasonic location, comprise stylophore 1 and nook closing member 4, nook closing member 4 comprises needle point 6, nook closing member body, nook closing member body comprises nook closing member body head end 5 and non-nook closing member body head end 8, needle point 6 is placed on stylophore, and the outer wall of nook closing member body head end 5 and the inwall of stylophore 1 are fitted, and has space between the outer wall of non-nook closing member body head end 8 and the inwall of stylophore 1.
Shown in composition graphs 1, Fig. 2, Fig. 3, nook closing member 4 stretches in stylophore 1, and the needle point 6 of nook closing member 4 is placed on the stylophore head end 2 of stylophore 1, and the afterbody 3 of stylophore 1 matches with the afterbody 7 of nook closing member 4, is convenient to the taking-up of nook closing member 4.
Be understandable that, in order to the inwall of the outer wall and stylophore 1 that realize nook closing member body head end 5 is fitted, stylophore 1, nook closing member body head end 5 can be allowed to be cylindrical, stylophore 1 inner hollow, for stretching into nook closing member 4, the diameter of stylophore 1 and the diameter of nook closing member body head end 5 match, thus the outer wall of nook closing member body head end 5 and the inwall of stylophore 1 are fitted.
In order to the laminating of the inwall of the outer wall and stylophore 1 that better realize nook closing member body head end 5, do not affect the development effect of puncture needle under ultrasonic state, the length of nook closing member body head end 5 is 1mm simultaneously.
Non-nook closing member body head end 8 can be cylindrical, to air, there is strong reflexive due to ultrasonic, in order to improve the development state of percutaneous needle under ultrasonic effect of applicable B ultrasonic location, the diameter of non-nook closing member body head end is less than the diameter of stylophore by 1/4 ~ 1/2, and namely the diameter of non-nook closing member body head end is 1/2 ~ 3/4 of the diameter of stylophore.
It should be noted that, in order to better realize the puncture effect of nook closing member, nook closing member can be formed in one structure.
By fitting at the outer wall of nook closing member body head end and the inwall of stylophore, then between the outer wall of non-nook closing member body head end and the inwall of stylophore, there is space, to air, there is strong reflexive due to ultrasonic, the development state of percutaneous needle under ultrasonic effect of applicable B ultrasonic location of the present utility model can be improved.
