Abstract
The utility model discloses a down visible pjncture needle of B ultrasonic guide, including puncture needle body and needle cover, the inside pinhole that is equipped with of needle cover, puncture needle body locate in the pinhole of needle cover, the one end of needle cover be equipped with visibility region under the B ultrasonic, the B ultrasonic under visibility region for the surperficial sand -blast treating of needle cover. One end through at needle cover sets up visibility region under the B ultrasonic, under the B ultrasonic visibility region can be under the B ultrasonic high -visible puncture needle body's puncture route, the success rate of puncture obtains very big promotion, improves the puncture success rate of clinician in being percutaneous nephrolithotomy.
Description
Technical field
This utility model relates to a kind of puncture needle, and particularly a kind of B ultrasonic guides lower visible puncture needle.
Background technology
Current Urology Surgery treatment renal calculus percutaneous kidney mirror art, the kidney aggregation system and first Percutaneous nephrolith-otomy will puncture, urological surgeon is familiar to observing puncture needle under x-ray, but because use the puncture of x-ray orientation direction to have lonizing radiation injury, most doctor is caused to have the feared state of mind, and it is also unfavorable to patient, therefore use the puncture of B ultrasonic Guided Percutaneous kidney mirror more and more extensive, but require during B ultrasonic guided puncture that clinical urological surgeon will have certain B ultrasonic knowledge, observing puncture needle path under B ultrasonic, can not to observe puncture needle path under x-ray directly perceived like that, clear, thus cause B ultrasonic guided puncture to be easy to puncture failure.Verify in a large number in clinical through us, the reason led to the failure and percutaneous needle have substantial connection, and therefore we just devise a percutaneous needle under B ultrasonic with sensitive part, so just can solve clinical practical problem.
Utility model content
For above-mentioned the deficiencies in the prior art part, the problem that this utility model solves is: traditional puncture needle is easy to puncture failure at B ultrasonic guided puncture.
For solving the problem, the technical scheme that this utility model is taked is as follows:
A kind of B ultrasonic guides lower visible puncture needle, comprises puncture needle body and needle guard; Described needle guard inside is provided with pin hole; Described puncture needle body is located in the pin hole of needle guard; One end of described needle guard is provided with visibility region under B ultrasonic; Under described B ultrasonic, visibility region is the process of needle guard surface sand-blasting.
Further, described puncture needle body and needle guard are made up of stainless steel material.
Further, the diameter of described needle guard is 1.2 ~ 1.5mm; The length of described needle guard is 195 ~ 205mm.
Further, under described B ultrasonic, the length of visibility region is 18 ~ 21mm.
Further, the other end of described needle guard is provided with the first Handheld Division; Described puncture needle body one end is provided with the second Handheld Division; The second described Handheld Division is connected on the first Handheld Division.
Further, the described puncture needle body other end is provided with the syringe needle of diamond structure; The length of described syringe needle is 1.9 ~ 2.1mm.
Further, under described B ultrasonic, the lower end of visibility region and the distance of puncture needle body lower end are 4 ~ 6mm.
The beneficial effects of the utility model
1. by visibility region under arranging B ultrasonic in one end of needle guard, under B ultrasonic visibility region can under B ultrasonic the puncture path of high-visible puncture needle body, the success rate of puncture is greatly improved, and improves clinicist and is doing the puncture success rate in PCN operation.
2. this utility model arranges the first Handheld Division at the other end of needle guard, in puncture needle body one end, the second Handheld Division is set, second Handheld Division is connected on the first Handheld Division, it is hand-held that such vibrational power flow is not only convenient to staff, and needle guard plays spacing effect to puncture needle body, structure is ingenious, reasonable in design.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of this utility model needle guard.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model content is described in further detail.
As illustrated in fig. 1 and 2, a kind of B ultrasonic guides lower visible puncture needle, comprises puncture needle body 2 and needle guard 1.In this utility model, puncture needle body 2 and needle guard 1 are all made up of rustless steel.Described needle guard 1 inside is provided with pin hole 13.Described puncture needle body 2 is located in the pin hole 13 of needle guard 1.One end of described needle guard 1 is provided with visibility region 11 under B ultrasonic.Under described B ultrasonic, visibility region 11 carries out blasting treatment by needle guard 1 surface.Further preferably, the diameter of described needle guard 1 is 1.2 ~ 1.5mm, and the diameter of the preferred needle guard 1 of this utility model is 1.3mm.The length of needle guard 1 is 195 ~ 205mm, and the length of the preferred needle guard 1 of this utility model is 200mm.Further preferably, under described B ultrasonic, the length of visibility region 11 is 18 ~ 21mm, and under the preferred B ultrasonic of the present embodiment, the length of visibility region 11 is 20mm.Further preferably, the other end of described needle guard 1 is provided with the first Handheld Division 12.Described puncture needle body 2 one end is provided with the second Handheld Division 22.The second described Handheld Division 22 is connected on the first Handheld Division 12.Further preferably, described puncture needle body 2 other end is provided with the syringe needle 21 of diamond structure.The length of described syringe needle 21 is 1.9 ~ 2.1mm, and the length of the preferred syringe needle of the present embodiment is 2mm.Further preferably, under described B ultrasonic, the lower end of visibility region 11 and the distance of puncture needle body 2 lower end are 4 ~ 6mm, the distance of the preferred 5mm of this utility model.
This utility model is by visibility region 11 under arranging B ultrasonic in one end of needle guard 1, under B ultrasonic visibility region 11 can under B ultrasonic the puncture path of high-visible puncture needle body 2, the success rate of puncture is greatly improved, and improves clinicist and is doing the puncture success rate in PCN operation.This utility model arranges the first Handheld Division 12 at the other end of needle guard 1, in puncture needle body 2 one end, the second Handheld Division 22 is set, second Handheld Division 22 is connected on the first Handheld Division 12, it is hand-held that such vibrational power flow is not only convenient to staff, and needle guard 1 pair of puncture needle body 2 plays spacing effect, structure is ingenious, reasonable in design.In this utility model, puncture needle body 2 enters from the second upper end, Handheld Division 22 of needle guard 1 is interspersed.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
