Problems solved by technology

This method cannot quickly and intuitively determine the location of the lesion, and the inspection operation is complicated and cumbersome, which is not conducive to shortening the operation time
[0005] When the ultrasound microprobe is used in conjunction with the guide sheath, the guide sheath usually causes the bending part of the bronchoscope to be stiff, and the pathological tissue specimens obtained are relatively small. In addition, the guide catheter is a disposable consumable and the price is high

no. 1 Embodiment

[0036] see Figure 1 to Figure 3 , the first specific embodiment of the present invention provides an ultrasonic microprobe and an ultrasonic endoscopy system provided with the ultrasonic microprobe.

[0037] The ultrasonic microprobe includes an ultrasonic transducer 1 , a driving shaft 3 and a catheter 2 , the driving shaft 3 is connected to the ultrasonic transducer 1 , and the ultrasonic transducer 1 is installed in the catheter 2 . Wherein, a plurality of positioning marks 20 are arranged on the outer surface of the distal tube section of the catheter 2 along the axial direction, and the plurality of positioning marks 20 constitute a distance scale. In the distance scale, there is a preset distance greater than zero between adjacent positioning marks 20, and the preset distance is preferably set to 2mm, or 3mm, or 5mm, or 10mm, or 15mm, or other according to actual needs. suitable parameters.

[0038] The ultrasonic endoscopic inspection system includes an endoscope 5 a...

no. 2 Embodiment

[0053] The second specific embodiment of the present invention provides an ultrasonic microprobe, which differs from the ultrasonic microprobe provided in the first specific embodiment of the present invention only in that each positioning mark 20 on the catheter 2 is a polygonal symbol, and, Starting from the distal end of the catheter 2, in the direction of gradually approaching the proximal end, every X positioning marks 20 form a group, X is a natural number greater than zero, preferably X=3, or X=5, or other values . Wherein: the positioning marks 20 in the same group have the same shape and the same size, and the positioning marks 20 in different groups have different shapes or different sizes or different shapes and sizes, so as to facilitate observation and counting. For example, see Figure 4 , the first group of positioning marks 20 are all rectangular symbols, and the second group of positioning marks 20 are all triangular. But it is not limited thereto. In other ...

no. 3 Embodiment

[0055] See Figure 5 , the third specific embodiment of the present invention provides an ultrasonic microprobe, which differs from the ultrasonic microprobe provided in the second specific embodiment of the present invention only in that each positioning mark 20 is composed of multiple graphics along the catheter 2 The circumferential direction is arranged in a circular array to form a circular pattern, so as to ensure that the positioning marks 20 can be observed in different angle directions, and ensure that the positioning marks 20 can also be observed when the catheter 2 is twisted.

[0056] Finally, it should be noted that in different specific embodiments, even on the same catheter 2 in the same specific implementation, the positioning marks 20 can be formed through various processing methods, and the positioning marks 20 can also be designed into various structures or The shape, as long as it does not affect the normal transmission of ultrasonic waves and can be clearl...

Abstract

The invention discloses an ultrasound micro-probe, an ultrasound endoscopy system and a biopsy sampling system, and belongs to the field of medical apparatus and instruments. The ultrasound micro-probe comprises an ultrasound energy converter, a driving shaft and a guide pipe, wherein the driving shaft is connected with the ultrasound energy converter; the ultrasound energy converter is installed in the guide pipe; a plurality of positioning marks are distributed along the axial direction of the outer side surface of the far-end pipe segment of the guide pipe; and a preset distance greater than zero is formed between adjacent positioning marks so as to form a distance scale. Since the guide pipe of the ultrasound micro-probe is provided with the distance scale, a doctor can accurately and visually determine a focus position under the visual field of an endoscope, accurate positioning guidance is provided for subsequent biopsy sampling, a clinical pain spot that the focus can not be quickly and visually positioned at present is solved, a clinical examination operation is simplified, clinical consumable item cost is lowered, and surgery time is shortened.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to an ultrasonic microprobe, an ultrasonic endoscopy system equipped with the ultrasonic microprobe, and a biopsy sampling system that combines biopsy forceps with the ultrasonic endoscopy system . Background technique [0002] Endobronchial ultrasonography (REBUS) can clearly show the surface changes of the respiratory mucosa and the tiny lesions of the submucosal deep tissue structure due to its high frequency and small diameter. It plays a very important role in the clinical diagnosis and treatment of the trachea, especially the peripheral bronchi. [0003] Intrabronchial ultrasound microprobe can quickly confirm and locate lesions during operation, further clarify suspicious lesions in chest CT examination, improve the diagnosis rate, and shorten the operation time of bronchoscopy. If necessary, biopsy the lesions confirmed by the ultrasound microprobe for furth...
