Embodiment 1

[0039]Embodiment 1, the present invention is a directional puncture sampling device for treating liver diseases, including a telescopic support 1, which provides a support base for subsequent structures, and is characterized in that the upper end of the telescopic support 1 is connected with an upper fixing ring 2, The top surface of the upper fixed ring 2 is fixed on the telescopic bracket 1, here can adopt bolt connection, or adopt other common fixing methods, the bottom of the upper fixed ring 2 is connected with the lower fixed ring 3 by bolts, the The upper fixed ring 2 and the lower fixed ring 3 are coaxially installed, and there is a certain distance between the two. The coaxial rotation between the upper fixed ring 2 and the lower fixed ring 3 is installed with an external gear ring 4 and the inner toothed ring gear 5, the outer toothed ring gear 4 and the inner toothed ring gear 5 can rotate between the upper fixed ring 2 and the lower fixed ring 3, and the outer diame...

Embodiment 2

[0040] Embodiment 2, on the basis of Embodiment 1, block reset torsion springs are respectively installed between the first block 801 and the second block 802 and the internal tooth ring gear 5, when the first block 801 or the second block After the second block 802 swings to a certain extent, it can be reset by the block reset torsion spring, and the first block 801 and the second block 802 are integrally connected with the first block 803 and the second block 804 respectively. The locking tooth 16, when the ultrasonic probe 12 is pressed outward by the arc-shaped pressure plate 11, the first block 801 and the second block 802 can be blocked by the first block 803 and the second block 804, so that the two do not It will continue to swing outwards to realize the fixing of the ultrasonic probe 12. Anti-skid pads are installed on the arc-shaped pressing plate 11, the first stopper 801 and the second stopper 802. When the ultrasonic probe 12 is fixed between the three, The anti-s...

Embodiment 3

[0041] Embodiment three, on the basis of embodiment one, a disinfection bottle installation block is fixed on the outer contour surface of the front side of the internal tooth ring gear 5, and a disinfection bottle installation block is provided with a disinfection bottle installation groove 17, and the disinfection bottle is installed On the inner walls of both sides of the groove 17, fixed sliders 18 are respectively rotated and installed, and the two fixed sliders 18 can swing on the two side walls of the disinfection bottle installation groove 17. The left and right ends of the disinfection bottle 13 are respectively provided with The fixed chute 19 that two described fixed sliders 18 cooperate to install, the disinfection bottle 13 can be fixed on the two fixed sliders 18 by the fixed chute 19 on both sides, so that the disinfection bottle 13 can be placed in the disinfection bottle installation groove 17 Swing, during disinfection, the operator can sterilize the patient's...

Abstract

The invention provides directional puncture sampling equipment for treating hepatopathy. The problems of low positioning precision, low puncture efficiency, inaccurate positioning and inaccurate needle insertion depth in the prior art are solved. The equipment comprises a telescopic support which is connected with an upper fixed ring. A lower fixed ring is connected with the lower part of the upper fixed ring. An outer gear ring and an inner gear ring are rotationally arranged between the upper fixed ring and the lower fixed ring. A one-way wheel is coaxially mounted on the outer gear ring. Afirst gear is mounted on the lower fixed ring. A second gear is meshed beside the first gear. The second gear is meshed with the inner gear ring. A probe mounting groove is formed in the inner gear ring. A first stop block and a second stop block are rotationally arranged on the two sides of the probe mounting groove. An arc-shaped pressing plate is mounted in the probe mounting groove. An ultrasonic probe is mounted in the probe mounting groove. A puncture needle is mounted on the rear side of the one-way wheel. According to the invention, position conversion among the ultrasonic probe, a disinfection bottle, an anesthetic needle and the puncture needle can be achieved; and liver and puncture can be positioned more accurately.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a directional puncture sampling device for treating liver diseases. Background technique [0002] Puncture, a commonly used surgical term in medicine, is a diagnosis and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for testing, injecting gas or contrast agent into the body cavity for contrast examination, or injecting drugs into the body cavity. The purpose of puncture is to draw blood for testing , Blood transfusion, infusion and catheterization for angiography. [0003] Liver biopsy is to use a liver puncture needle to draw liver tissue for pathological examination. It has been widely used clinically in the diagnosis of hepatitis, fatty liver, liver cancer and other diseases. It is a method that can directly understand the pathological changes of liver tissue and make a more objective and accurate diagnosis. The ...
