Problems solved by technology

[0004] However, there are still many shortcomings in its actual use. For example, the existing ultrasonic detection and biopsy forceps insertion are completed at two times, and cannot coexist in the airway at the same time. The detected position may not be the same position when it is fed into the biopsy forceps for sampling, causing the biopsy forceps to deviate from the actual position

Abstract

The invention discloses a device and method for bronchial ultrasonic detection and biopsy synchronous sampling, and particularly relates to the technical field of medical equipment. The device comprises a double-working mechanism; the double-working mechanism comprises a bronchoscope body, working channels are formed in the bronchoscope body, material taking air bag sleeves are arranged in the working channels respectively, and the cross section of each material taking air bag sleeve is circular; a first air cavity is formed in each material taking air bag sleeve, the material taking air bag sleeves are made of an artificial biological film material, guide wires are arranged in the material taking air bag sleeves, one side of each material taking air bag sleeve is fixedly provided with a conveying air pipe, and one end of each material taking air bag sleeve is fixedly provided with an inflation switching valve. By arranging the double-working mechanism, the biopsy mode can be changed,the device can be adapted to positioning of any bronchoscope and can be adjusted along with a bronchoscope, the flexibility is improved, the working view field can be expanded, sampling biopsy is carried out on peripheral bronchia in the lung field, and the situation that sampling using biopsy forceps deviates from the actual position is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and more specifically, the invention relates to a device and method for synchronous sampling of bronchial ultrasound detection and biopsy. Background technique [0002] A flexible bronchoscope with an outer diameter of about 4mm has an operating channel in the middle, which is too thin to place an ultrasound probe and biopsy forceps at the same time. Both the ultrasonic probe and the biopsy forceps are about 2 mm in diameter. The existing method is to insert the ultrasonic probe with a bronchoscope, which contains the ultrasonic probe for detection, and moves to the desired biopsy position, then pulls out the ultrasonic probe, and inserts the biopsy forceps again. Insertion completes the biopsy. [0003] The utility model patent of patent application publication number CN204734463U discloses a bronchoscopic lung peripheral ultrasound guide sheath, which includes a silicone tube body. W...
