Description

A kind of Nephrology dept.'s puncture needle

Technical field

The utility model is related to the field of medical instrument technology, specifically, being related to a kind of Nephrology dept.'s puncture needle.

Background technology

In clinical treatment activity, renal puncture has very important status during Nephrology dept.'s medical diagnosis on disease, should Method has high accuracy, can correct the various deviations appeared in routine inspection index, and acute nephritis is integrated Sign, Primary Nephritis, renal function, which is drastically gone bad, to be turned, and is suffered from again by the nephrosis that long-term treatment is not felt any better and be required for passing through kidney The method of puncture to the state of an illness accurately differentiate and predict.

Existing kidney puncture needle is mainly made of needle body, needle handle and needle core, and needle handle volume is smaller, and such hand pinches needle handle It is easy to fall off, and is difficult that control punctures weight in piercing process, depth of needle will be measured with ruler repeatedly, give medical matters Personnel make troubles, and influence to puncture quality.And can increase needle body frictional force in needle body surface setting scale, it is given in piercing process Patient increases pain sense of discomfort.

Currently, also there is part puncture needle to be provided with graduated scale, but structure is more complicated, and puncture needle overall volume is bigger, Medical worker uses inconvenience.

Utility model content

The purpose of the utility model is to provide a kind of Nephrology dept.'s puncture needles, to solve above-mentioned technical problem.

To achieve the goals above, the utility model uses following technical scheme：

A kind of Nephrology dept.'s puncture needle, including needle ontology and graduated scale, the graduated scale are the transparent pipe with sliding slot, institute State graduated scale cross section be inc circle, the needle ontology sliding plug in the graduated scale, the graduated scale Length is identical as the length of needle ontology；The needle ontology includes needle body, the needle point positioned at needle body bottom end and setting in needle The needle body lid on body top, the needle body are covered equipped with needle body handle, and the needle body handle is extended to by the sliding slot on graduated scale Outside graduated scale, the needle body handle can drive needle ontology to be slided up and down in graduated scale；The graduated scale bottom end is equipped with locating ring, The locating ring is equipped with fixed handle.

Preferably：The zero graduation line of the graduated scale is arranged in the starting point on graduated scale top.

Preferably：The needle body whole body is equipped with closed air blanketing.

Preferably：It is equipped with anti-skid chequer on the needle body handle and fixed handle.

Advantageous effect：Compared with prior art, Nephrology dept.'s puncture needle described in the utility model, simple in structure, volume It is small, it is very easy to use；Depth of needle is very intuitive, is easy to control；The setting of two handles makes medical worker hold needle More securely, operation is easier.

Description of the drawings

Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model；

Fig. 2 is the schematic cross-sectional view at needle body lid in Fig. 1；

Fig. 3 is the schematic cross-sectional view at locating ring in Fig. 1.

Specific implementation mode

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

- Fig. 3 referring to Fig.1, Nephrology dept.'s puncture needle described in the utility model, including needle ontology 1 and graduated scale 2.

The graduated scale 2 is the transparent pipe with sliding slot, and the cross section of the graduated scale 2 is inc circle, described For 1 sliding plug of needle ontology in the graduated scale 2, the length of the graduated scale 2 is identical as the length of the needle ontology 1.It is described The zero graduation line of graduated scale 2 is arranged in the starting point on 2 top of graduated scale.Length of the graduated scale 2 beyond needle body lid 12 is inserting needle Depth, more intuitively, it is easier to control.2 bottom end of the graduated scale is equipped with locating ring 3, and the locating ring 3 is equipped with fixed handle 30。

The needle ontology 1 include needle body 10, positioned at 10 bottom end of needle body needle point 11 and needle on 10 top of needle body is set Body lid 12, the needle body lid 12 are equipped with needle body handle 13, and the needle body handle 13 extends to quarter by the sliding slot on graduated scale 2 It spends outside ruler 2, the needle body handle 13 can drive needle ontology 1 to be slided up and down in graduated scale 2.

10 whole body of the needle body is equipped with closed air blanketing 4.The setting of air blanketing 4 enables the profile of needle body to exist Clearly indicated in ultrasound display screen, medical worker is easy to distinguish in kidney and surrounding tissue, can it is more acurrate really Determine site of puncture.

It is equipped with anti-skid chequer on the needle body handle 13 and fixed handle 30.It is more firm that medical worker holds needle in operation Gu, operation be easier.

The operating method of the utility model is summarized as follows：

Before use, needle ontology 1 is plugged on completely in graduated scale 2；In use, pressing needle body handle 13 makes needle ontology 1 carve Required depth of needle (length of the graduated scale 2 beyond needle body lid 12 is depth of needle) is slided down in degree ruler 2, passes through positioning Trip bolt 31 on ring 3, which is realized, to be fixed, and holds needle body handle 13 and fixed handle 30 is punctured.

The technical characteristics and basic functional principle of the utility model have been shown and described above.Those skilled in the art It should be appreciated that described in above-described embodiment only illustrate the principles of the present invention, do not depart from the spirit of the present invention and Under the premise of range, the utility model also has various changes and improvements, these changes and improvements both fall within claimed sheet Within the scope of utility model.The utility model requires protection scope is by claims and its equivalent thereof.
