Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to biopsy needle device.
Background
The percutaneous lung aspiration biopsy under the guidance of CT has important diagnosis and differential diagnosis values in the space occupying lesion of the lung, and is an important means for clinically diagnosing the lung cancer. However, the precise puncture position, angle and depth are important factors for ensuring the success of the percutaneous pneumopuncture under the guidance of CT and reducing the risk of complications of patients. The operating doctor determines the needle insertion angle according to subjective judgment of the operating doctor, however, in actual operation, the focal tissue cannot be accurately taken out due to slight needle insertion angle difference, repeated puncture is caused, and the risks of puncture failure and complications such as pneumothorax and hemorrhage of a patient are increased.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a biopsy needle device that structural design is reasonable, can conveniently adjust puncture angle.
In order to solve the problem, the utility model discloses a fixing base, fixing base include an arc, are equipped with the slide rail at the up end of arc and along the cambered surface of arc, and the slide rail bottom is equipped with logical groove, is equipped with a plurality of slider in the slide rail, is equipped with on the slider and leads to the communicating through-hole of groove, is equipped with the biopsy needle on one of them slider or a plurality of slider, and the biopsy needle passes the through-hole of slider.
As a further improvement of the utility model, the fixing parts are arranged at the two ends of the arc-shaped plate, and the slide rail is arranged on the arc-shaped plate and the fixing parts.
As a further improvement of the utility model, the bottom of the fixed part is provided with an adhesive layer.
As a further improvement, the slide rail is provided with a concave chute along the extending direction of the slide rail at the inner wall surface of the slide rail, and the two ends of the slide block are provided with protrusions matched with the chute.
As a further improvement, the utility model is provided with a first magnet layer on the inner wall surface of the sliding groove and a second magnet layer which can attract the first magnet layer on the outer surface of the lug boss.
As a further improvement of the utility model, the side of the arc plate is provided with angle scales.
As a further improvement of the utility model, the upper end of the sliding block is higher than the upper end face of the arc-shaped plate.
The utility model has the advantages that: the fixing base is placed at the disease position, then slides the slider in the slide rail to the angle of puncture, then with the biopsy of slider to the human puncture can, because the biopsy needle is located on the slider, can play the effect of direction like this at the puncture in-process of biopsy needle, guaranteed the stability of puncture process, can guarantee the accuracy of the angle of puncture simultaneously.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a connecting structure diagram of the sliding block and the fixing base of the present invention.
Fig. 3 is a connecting structure diagram of the sliding block and the sliding rail of the present invention.
Detailed Description
As shown in figures 1 to 3, the utility model comprises a fixing base, the fixing base comprises an arc plate 1, fixing parts 2 are arranged at two ends of the arc plate 1, an adhesive layer 3 is arranged at the bottom of the fixing parts 2, a slide rail 4 is arranged on the upper end surface of the arc plate 1 and along the arc surface of the arc plate 1 and the upper end surface of the fixing parts 2, a through groove 5 is arranged at the bottom of the slide rail 4, a plurality of slide blocks 6 are arranged in the slide rail 4, the upper end of each slide block 6 is higher than the upper end surface of the arc plate 1, an inner wall surface of the slide rail 4 which is oppositely arranged is provided with an inwards concave slide groove 7 along the extending direction of the slide rail 4, bulges 8 which are matched with the slide groove 7 are arranged at two ends of the slide block 6, a first magnet layer 9 is arranged on the inner wall surface of the slide groove 7, a second magnet layer 10 which can attract the first magnet layer 9 is arranged on the outer surface of the bulges 8, a through hole, the biopsy needle 12 passes through the through hole 11 of the slide block 6, and the side surface of the arc-shaped plate 1 is provided with angle scales.
The utility model has the advantages that: the fixing seat is placed on a diseased part and is fixed with the body of a patient through the adhesive layer 3 on the fixing part 2, then the slide block 6 in the slide rail 4 is slid to the puncture angle, and then the biopsy needle 12 of the slide block 6 is punctured for the human body and the focal tissue is taken out. Because the biopsy needle 12 is arranged on the sliding block 6, the guide function can be realized in the puncture process of the biopsy needle 12, the stability of the puncture process is ensured, and meanwhile, the accuracy of the puncture angle can be ensured. The side of the arc-shaped plate 1 is provided with angle scales, so that the puncture angle can be conveniently known. Because the upper end of the sliding block 6 is higher than the upper end surface of the arc-shaped plate 1, the sliding block 6 is convenient for an operator to slide in the sliding rail 4. Because the internal wall at spout 7 is equipped with first magnet layer 9, is equipped with the second magnet layer 10 that can attract mutually with first magnet layer 9 at the surface of bellying 8, slides the angle of puncture like this when slider 6, can fix slider 6 in slide rail 4 through the adsorption of first magnet layer 9 with second magnet layer 10, has further guaranteed the convenience of operation and the stability of puncture process.
