Description

Kidney puncture needle special for nephrology department

technical field

The utility model relates to a special kidney puncture needle for nephrology.

Background technique

It is well known that kidney biopsy is an important method for diagnosing kidney diseases. Most of the kidney puncture needles used at present are combined structures of needle handle, needle body and needle core. When the patient performs kidney puncture, the needle handle is easy to slip off when pinched by hand, and the depth of needle insertion must be repeatedly measured with a ruler during puncture, which is very inconvenient. After measuring the puncture depth during puncture, fix it on the puncture needle by hand to determine the depth of the puncture needle. However, finger movements are prone to occur during the operation, which will affect the accuracy of puncture depth. The current surgical operation is generally assisted by ultrasound equipment, and the puncture operation is assisted by the display screen of the ultrasound equipment. However, the projection of ordinary puncture needles under ultrasound is very unclear, and it is difficult for medical staff to distinguish the kidney and surrounding tissues, which leads to inaccurate puncture sites. Yes, it has made the work of medical staff more difficult.

Utility model content

In order to overcome the deficiencies in the background technology, the utility model discloses a special kidney puncture needle for nephrology. Through the utility model, the needle body can be clearly distinguished from the kidney and the surrounding tissues through ultrasonic waves, effectively avoiding the need for the puncture needle Shake or slide.

Realize the technical scheme of the utility model as follows:

A special kidney puncture needle for nephrology, comprising a needle handle and a needle core, a base is provided at the lower end of the needle handle, the base is fixedly connected with the needle handle, a needle core is provided at the lower part of the base, and a needle core is arranged at the lower end of the needle core A transparent blind tube is provided on the outside, the transparent blind tube and the needle core are fixedly connected to the base, and an interlayer collar is arranged at the front end of the needle core, and the interlayer collar is fixedly connected to the needle core, and on the transparent blind tube There is a collar, a magnifying glass is arranged on the collar, and a scale is set on the outer edge of the transparent blind tube. The telescopic rods are fixedly connected to the base, the telescopic rods are distributed on both sides of the transparent blind tube, and suction cups are respectively arranged at the lower ends of the telescopic rods.

In the kidney puncture needle special for nephrology, the interlayer collar seals the interlayer between the needle core and the transparent blind tube to form a closed cavity containing air.

In the kidney puncture needle special for nephrology, liquid is injected into the interlayer collar at the front end of the needle core.

As for the special kidney puncture needle for nephrology, the total length of the telescopic rod is not less than the length of the needle core.

As for the kidney puncture needle dedicated for nephrology, the collar 4 on the transparent blind tube is movably connected with the transparent blind tube.

The beneficial effect of the utility model is that the special kidney puncture needle for nephrology described in the utility model can generate strong reflectivity to ultrasonic waves through the interlayer containing air on the puncture needle and the liquid in the interlayer collar, which not only The kidney and surrounding tissues can be clearly distinguished through the ultrasonic display screen, and through the difference of reflecting materials, it can also help the medical staff to understand the position of the needle core and the needle head more clearly, and it is convenient for the medical staff to judge the needle insertion; through the collar and the collar The magnifying glass on the top allows the medical staff to understand the depth of the needle more clearly and directly; the telescopic rods on both sides of the base can help the medical staff to stabilize the puncture needle, avoiding the damage to the patient caused by the shaking or slipping of the puncture needle, and helping the medical staff More stable puncture; the utility model is simple in structure, easy to use, and provides safety guarantee for kidney skin puncture work.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

In combination with the structure shown in accompanying drawing 1 or 2, a kidney puncture needle dedicated to nephrology includes a needle handle 1, a magnifying glass 3 and a scale 10, and a base 2 is provided at the lower end of the needle handle 1, and the base 2 is connected to the needle handle 1 Fixedly connected, a needle core 8 is provided at the bottom of the base 2, and a transparent dead tube 6 is arranged outside the needle core 8, and the transparent blind tube 6 and the needle core 8 are fixedly connected with the base 2, and the The front end of needle core 8 is provided with interlayer collar 7, and described interlayer collar is fixedly connected with needle core 8, is filled with liquid in the interlayer collar 7 of described needle core 8 front end, and described interlayer collar 7 will needle The interlayer seal between the core 8 and the transparent blind tube 6 forms a closed cavity containing air, a collar 4 is provided on the transparent blind tube 6, a magnifying glass 3 is arranged on the collar 4, and the transparent blind tube The collar 4 on the tube 6 is movably connected with the transparent blind tube 6, and a scale 10 is provided on the outer edge of the transparent blind tube 6. The scale 10 corresponds to the magnifying glass 3 on the collar 4, and the bottom of the base 2 Both sides are provided with telescopic rods 5 respectively, and the telescopic rods 5 are fixedly connected with the base 2, and the telescopic rods 5 are distributed on both sides of the transparent blind tube 6, and the total length of the telescopic rods 5 is not less than that of the needle core 8. length, suction cups 9 are respectively provided at the lower ends of the telescopic rods 5 .

When implementing the special kidney puncture needle for nephrology described in the utility model, when puncturing the kidney skin of a patient, the telescopic rods 5 on both sides of the base 2 are first stretched, and the suction cups 9 on the telescopic rods 5 are adsorbed on the waist of the patient. When the adsorption is stable, the medical staff can hold the needle handle 1 firmly with one hand, support the base 2 with the other hand, and slowly push the needle handle 1. During the advancing process, the collar 4 on the transparent blind tube 6 slides upward slowly as it is inserted. The medical staff can judge the penetration depth by observing the scale 10 on the transparent blind tube 6 through the magnifying glass 3 on the collar 4; when it is relatively close to the patient's kidney, the medical staff can observe the internal condition of the patient through ultrasonic waves and ultrasonic display equipment , through the air between the transparent blind tube 6 and the needle core 8 and the liquid in the interlayer collar 7, the ultrasonic wave can be reflected more strongly, so that the ultrasonic display device can more clearly show the position of the puncture needle, as well as the kidney and other organs. The specific conditions of the surrounding tissue are convenient for medical staff to puncture; when the puncture is over, the medical staff slowly pulls the needle handle 1 out, and when the needle core 8 and transparent blind tube 6 leave the patient's body completely, they will be absorbed in the patient's body by hand. The suction cup 9 on the patient's waist is taken off, the telescopic rod 5 is retracted, and the puncture needle is cleaned.

Inspired by the above ideal embodiment according to the utility model, through the above description content, relevant staff can completely make various changes and modifications within the scope of not deviating from the technical idea of the utility model. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims.
