Description

Needle stabilizer for puncture

Technical Field

The utility model relates to the field of medical equipment, specifically a syringe needle stabilizer is used in puncture.

Background

Renal biopsy is commonly called renal puncture. Due to the wide variety of kidney diseases and the complex etiology and pathogenesis, the clinical manifestations of many kidney diseases are not completely consistent with the histological changes of the kidney. To further confirm the pathology of the disease, the patient is diagnosed with a particular disease species, which requires a renal biopsy. In recent years, with the development of science and technology, the updating of imaging equipment and the improvement of operation technology, the percutaneous kidney biopsy technology is widely developed, and the percutaneous kidney biopsy technology can directly observe the change of the kidney morphology of the kidney disease and can carry out serial observation. Due to the improvement of the puncture technology, the application of the immunohistochemical technology and the electron microscope, the diagnosis quality is greatly improved. Has become an important means for diagnosing, guiding treatment and prognosis of kidney diseases. Meanwhile, the medicine also makes contributions to the etiology and development trend of various glomerular diseases. The general procedure for renal biopsy is: 1) 2% lidocaine is applied to subcutaneous local anesthesia at the puncture point, and the skin is incised at the puncture point by about 1mm by using a sharp knife; 2) under the guidance of the B ultrasonic puncture bracket, the lumbar puncture needle is used for gradually local anesthesia to the outside of the renal capsule along the planned puncture path. 3) Taking a puncture needle to directly insert the needle from a skin anesthesia point under the guidance of ultrasound to puncture to the outside of the kidney capsule of the infrarenal pole, 4) installing a Bard puncture gun, using 1-grade (1.5cm) or 2-grade (2.0cm), when the kidney of a patient moves to a proper position, advising the patient to hold breath, avoiding the renal calyx of the renal pelvis at the position with the thickest essence of the infrarenal pole, opening a safety device, buckling a trigger, hearing 'gun sound', immediately withdrawing the needle, and ensuring the needle insertion time to be about 1 s. The pasteur puncture outfit is reset for 1 time, the specimen is exposed, the pasteur puncture outfit is placed on normal saline gauze, and the specimen is observed by naked eyes to determine the kidney tissue. Puncturing for 2-3 times. Need stabilize the puncture needle at puncture needle in-process and after the puncture, though puncture route under the guide of B ultrasonic, the syringe needle can take place to shake because manual operation, and the syringe needle can not be synchronous stable after the puncture, can cause puncture mouth to enlarge or puncture point error. Resulting in inaccurate diagnosis and treatment.

The guide pipe 3 is a hard pipe and is arranged on the upper end surface of the sucker 1. And is communicated with the sucker.

And a sealing soft rubber is filled in the guide pipe 3.

The lower ends of the sub-paster 4 and the mother paster 5 are fixed on two sides of the guide pipe 3 in a separated mode, and the upper ends of the sub-paster 4 and the mother paster 5 are attached.

The sponge post structure is characterized in that a plurality of sponge posts 9 with the same interval are arranged on the meshing surface of the sub-paster 4, jacks 8 are arranged on the sub-pasters 4 on two sides of each sponge post 9, clamping grooves 6 which are meshed with the sponge posts 9 are arranged on the mother pasters 5, and bolts 7 which are meshed with the jacks 8 are arranged on the mother pasters 5 at two ends of each clamping groove 6.

The utility model has the advantages that: make whole device be fixed in on the skin through sucking disc and ear subsides, thereby the meshing through sub-subsides and female subsides makes the syringe needle of inserting the inside of leading pipe stable, easy operation convenience. The whole device has simple structure and low cost and is a disposable appliance. Because this device can effectually avoid can not cause the puncture mouth to enlarge owing to the vibrations that manual operation produced at the puncture in-process and pierce the back syringe needle, the disease wound resumes soon, and is more accurate effective when the diagnosis is treated simultaneously.

Detailed Description

The technical solution of the present invention is further described by the following specific embodiments with reference to the accompanying drawings:

example 1

As shown in figures 1-4, a needle stabilizer for puncture comprises a sucker 1, an ear patch 2, a guide tube 3, a sub patch 4, a mother patch 5, a clamping groove 6, a plug 7, a jack 8 and a sponge column 9.

The device is divided into two parts, namely a skin fixing unit and a needle fixing unit.

The skin fixing unit is composed of a suction cup 1 and an ear patch 2 as shown in figure 1, wherein the suction cup 1 is a rubber cone-shaped disc, and the suction cup 1 is attached to the surface of the skin when in use. Two ear pastes 2 are arranged at the lower edge of the sucking disc 1, and the medical adhesive tape is adhered to the ear pastes 2 and the skin, so that the whole device is relatively stable on the skin and cannot move in the puncturing process.

The upper end surface of the sucker 1 is provided with a guide pipe 3, and the guide pipe 3 limits the puncture range for a small initial range. The length of the guide tube is defined between 1cm and. The guide tube 3 is filled with a sealing soft rubber, and the sucker 1 can still be ensured to be closely attached to the skin after the needle is penetrated.
