According to the device, the angle and the position of the puncture needle can be marked through the scales on the arc-shaped sheet by virtue of the strip-shaped projection lamp, so that the puncture needle can accurately puncture into the sampling channel for multiple times, and the probability of injuring a patient is reduced; through rapid and accurate angle positioning, the sampling time is shortened; the arc-shaped sheet, the L-shaped lamp bracket and the strip-shaped projection lamp are simple in structure and easy to manufacture.

Description

Technical Field

[0001] The utility model relates to the technical field of puncture biopsy, in particular to a thyroid puncture biopsy device. Background Art

[0002] Thyroid nodules are abnormal masses in the thyroid tissue. Before treatment, samples need to be taken for testing and analysis.

[0003] Thyroid nodule puncture is to puncture the thyroid lesion with a fine needle (22-25G) or a thick needle (13-18G) under the guidance of imaging (ultrasound / CT, etc.), obtain cell / tissue components from it, and diagnose the nature of the target lesion through pathology. For patients with compression symptoms caused by huge cystic lesions of the thyroid (such as dyspnea, dysphagia, hoarseness, etc.), puncture and fluid extraction decompression can temporarily alleviate the above symptoms.

[0004] During the puncture sampling process, the sampling channel must first be established, and then the puncture needle is used for puncture sampling. Depending on the severity of the patient's symptoms, some patients require 1-2 samplings, while others require 3-4 samplings. During puncture, the sample is generally taken by obliquely puncturing the skin from the position below the ultrasonic probe. After penetration, the area below the ultrasonic probe can be observed on the image on the display screen, but at the initial angle of penetration into the skin (the angle of penetration into the sampling channel), the ultrasonic image cannot be observed, making it difficult to accurately and smoothly penetrate the sampling channel, and it is easy to damage the patient (needle hole mouth). To this end, we propose a thyroid puncture biopsy device. Utility Model Content

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application; the terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] Example 1

[0031] See also Figure 1-4 A thyroid puncture biopsy device includes an L-shaped lamp holder 200 fixedly connected to one side of an ultrasonic probe 100, and strip projection lamps 202 are fixedly installed on the two L-shaped inner sides of the L-shaped lamp holder 200; it also includes an arc-shaped sheet 400 fixedly installed on one side of the ultrasonic probe 100, and a scale 401 is set on the upper surface of the arc-shaped sheet 400; when the puncture needle 300 is in the inner area of ​​the arc-shaped sheet 400, the strip projection lamp 202 illuminates the puncture needle 300 to form a projection at the position of the scale 401 on the surface of the arc-shaped sheet 400, and the inclination angle and specific position of the puncture needle 300 can be determined according to the projection position. Two projection lines will be formed on the arc-shaped sheet 400, corresponding to two different scales.

[0032] In this embodiment, the light emitting direction of the strip projection lamp 202 is arranged horizontally.

[0033] like Figure 4 As shown in FIG. 1 , a button 600 for controlling the switch of the strip projection light 202 is installed on one side of the upper part of the ultrasonic probe 100. The connection line of the strip projection light 202 runs through the ultrasonic probe 100 and is powered by the circuit in the ultrasonic probe 100.

[0034] Among them, the upper part of the inner side of the L-shaped lamp frame 200 is fixedly connected with a light shielding sheet 201. The purpose of the light shielding sheet 201 is to prevent the light from affecting the doctor's sight and affecting the doctor's observation. By blocking the light irradiated to the top, the doctor's sight will not be affected.

[0035] Example 2

[0036] Different from Example 1, during implementation, the angle between the light emitting direction of the strip projection lamp 202 and the horizontal plane is set to 5-30°. In Example 1, the horizontal irradiation light may still affect the doctor's line of sight. The inclined angle setting of this embodiment better protects the doctor's line of sight. At the same time, during projection, the mutual influence between the two strip projection lamps 202 is reduced (different tilt angles), and the projection is clearer; the horizontal height difference between the arc sheet 400 and the strip projection lamp 202 can be greater, so that the arc sheet 400 can be closer to the patient's skin position, and more space can be reserved for the operation of the puncture needle 300, which is more convenient.

[0037] Example 3

[0038] Different from the second embodiment, in this embodiment, one end of the arc-shaped piece 400 is fixedly connected with a U-shaped clip 500, and the U-shaped clip 500 is clamped on the lower part of the ultrasonic probe 100. Grooves 101 are respectively provided on both sides of the lower part of the ultrasonic probe 100, and the two ends of the U-shaped clip 500 are respectively clamped in the two grooves 101. A clamping groove 102 is provided at the inner bottom of the groove 101, and clamping points 501 that are clamped with the clamping groove 102 are provided on both inner side surfaces of the U-shaped clip 500.

[0039] The advantages of the above design are that the U-shaped clip 500 and the arc-shaped piece 400 are easy to disassemble and replace; easy to disinfect or replace in time for different patients; and prevent the germs on their surface from sticking to the skin of different patients and causing cross infection.

[0040] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive. Although the present application is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to perform equivalent replacement of some of the technical features therein. Any equivalent structure made using the contents of the specification and drawings of this application, directly or indirectly used in other related technical fields, is similarly within the scope of patent protection of this application.
