Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to a kind of renal fibroblast sampling anesthetic puncture one
Needle.
Background technique
It is typically being carried out by the way of renal needle biopsy when diagnosis of kidney disease, and current renal fibroblast
Biopsy mainly needs to include nearby carrying out local anaesthesia to kidney using anestetic needle and using under the cooperation of image technology
Puncture needle carries out puncturing two processes of sampling, but medical staff can usually suffer from when carrying out concrete operations as figure is inclined
Fat, it is too short to will appear syringe needle conventionally used for the 5ml injection needle of anesthesia at this time, can not pierce by the biggish patient of the small of the back fat thickness
The case where entering subcutaneous tissue, and also need to re-start puncture after carrying out local anaesthesia, secondary pain is brought for patient,
And in order to solve this problem, in such as domestic Publication No. 201481517U, publication date is the text of patent shown in 20100526
Part: " novel renal puncture needle " and at home Publication No. 201782805U, publication date are the text of patent shown in 20110406
Part: it is individually disclosed in " a kind of kidney puncture needle of easily distinguishable positioning " by being provided on the needle body of puncture needle and fiber crops
The connected anesthesia tube of liquor-saturated sap cavity is completed at the same time the operation of anesthesia and sampling during realizing one-time puncture, in its technical solution
In, it is voluntarily flowed down after opening control valve anesthesia sap cavity since the injection mode of its anesthesia liquid is relied primarily on, it is effective lacking
In the case where pressure injection, this injection mode process is slow, is not easy to be absorbed by patient in a short time and plays timely fiber crops
Liquor-saturated effect；On the other hand, be since the structure between anesthesia tube of stylophore is opposite it is fixed, carry out puncture sampling when
Can together bring anesthesia tube in kidney into is easy to cause the puncture orifice of kidney excessive, is unfavorable for later period healing.
Utility model content
It is used the technical problem to be solved by the utility model is to provide a kind of renal fibroblast and samples anesthetic puncture integrated needle, with
The anesthetic puncture integrated needle anaesthetic effect for solving to be currently used in renal needle biopsy is not good enough, while the puncture orifice at kidney is excessive, no
The problem of conducive to later period healing.
To solve the above problems, the utility model provides following technical solution:
A kind of renal fibroblast sampling anesthetic puncture integrated needle, it includes stylophore and anesthesia needle tubing；It is also equipped in stylophore
Puncture needle；Stylophore and the figure that the radial section for anaesthetizing needle tubing is all that a straight line and an arc curve are surrounded, and stylophore and fiber crops
One end of liquor-saturated needle tubing is all scarf；Stylophore and anaesthetize needle tubing side plane on along both axial direction have sliding slot and
Draw runner；Anesthesia needle tubing is fitted on stylophore by the draw runner and sliding slot, and the other end of anesthesia needle tubing is provided with work
Plug and block.
Preferably, stylophore and anaesthetize needle tubing outer tube diameter size it is identical, and the two scarf part it is sliceable be a cone
Body structure.
Preferably, scale marker is additionally provided on the outboard end of stylophore.
Preferably, the end of sliding slot and draw runner is not less than 1cm at a distance from the scarf end of anesthesia needle tubing to stylophore.
Further, the limiting device for limiting stylophore sliding is provided with far from one end of scarf in anesthesia needle tubing.
Preferably, sliding slot is dovetail slot, and the cross section of draw runner is the swallow matched with the tenon mouth of the dovetail slot
Tail shape.
The utility model the utility model has the advantages that
The utility model carries out the stylophore that anesthesia needle tubing is internally provided with puncture needle slideably by sliding slot and draw runner
Connection reduces repeated puncture secondary pain caused by patient, while can to guarantee that anestetic needle can puncture together with stylophore
Guarantee that anesthesia needle tubing is inserted at patient's hypodermis；And piston is set in the other end of anesthesia needle tubing, it is transported using piston
Movable property injects patient's body in the raw pressure drop anesthetic liquid medicine short time, to improve anaesthetic effect；After arcotic is injected
Stylophore can individually enter the kidney of patient, then carry out puncture sampling by puncture needle, guarantee its puncture orifice generated at kidney
It is not too big, in favor of later period healing；On the other hand, the utility model structure is simple, and it is convenient to operate, and can effectively prevent stylophore
And anesthesia needle tubing is detached from.
