Description

Technical Field

[0001] The utility model relates to the technical field of puncture needles, and particularly relates to a fixing bracket for a lung nodule puncture needle. Background Technique

[0002] A lung nodule puncture needle is a medical device used for diagnosing lung nodules. It is usually used in chest imaging examinations (such as puncture under CT guidance) to obtain tissue samples of lung nodules for pathological examination. The puncture needle generally includes a needle tube, a needle tip, and a grip. The needle tip is designed to be sharp to penetrate lung tissue, the needle tube is used to guide the sample, and the grip provides stability and control during operation;

[0003] The existing lung nodule puncture biopsy needles do not have a fixator. When puncturing to the nodule position, everyone has to exit the CT room for imaging, and the needle tail remains on the patient. Sometimes the needle may tilt with the patient's breathing, and the position may shift, thus affecting the actual treatment effect;

[0004] In view of this, we propose a fixing bracket for a lung nodule puncture needle. Content of the Utility Model

[0025] The present utility model will be further described below with reference to the embodiments.

[0026] Embodiment: A fixing bracket for a lung nodule puncture needle, comprising a grip 1 and a puncture needle body 2 slidably installed inside the grip 1. A plurality of scale bars 3 are fixedly arranged on the surface of the puncture needle body 2, and a positioning block 4 is sleeved on the surface of the puncture needle body 2. Among them, an airbag ring 12 is arranged on the surface of the puncture needle body 2, a fixing sleeve 5 is fixedly installed on the surface of the airbag ring 12, and a fixing member for fixing the puncture needle body 2 is arranged on the surfaces of the airbag ring 12 and the fixing sleeve 5;

[0027] Specifically, the puncture needle body 2 can be moved through the grip 1 to complete the puncture work. At the same time, the positioning block 4 is made of medical rubber. During puncture, the positioning block 4 can be moved to the puncture position of the patient, and then according to the position of the positioning block 4 reaching the corresponding scale bar 3, the puncture depth can be judged and controlled. At the same time, by using the fixing member arranged on the surfaces of the airbag ring 12 and the fixing sleeve 5 and cooperating with them, when all medical staff leave the CT room, the puncture needle body 2 and related components can be supported and fixed, so as to prevent phenomena such as deviation during the process;

[0028] Specifically, the fixing member includes an inflation tube 9 fixedly installed on the surface of the airbag ring 12. One end of the inflation tube 9 fixedly passes through the fixing sleeve 5. An inflation airbag body 8 is fixedly installed at the end of the inflation tube 9 passing through the fixing sleeve 5. A hanging ring 10 is fixedly installed at the end of the inflation airbag body 8 away from the inflation tube 9, and a hook 11 corresponding to the hanging ring 10 is fixedly installed on one side of the grip 1. The inflation airbag body 8 and the inflation tube 9 can be hung through the hanging ring 10 and the hook 11;

[0029] Specifically, by pressing the inflation airbag body 8, gas can be filled into the airbag ring 12, so that the airbag ring 12 expands and can tightly fit on the surface of the puncture needle body 2, thereby better fixing the puncture needle body 2. A valve is arranged in the inflation tube 9, which can prevent gas leakage when gas enters the airbag ring 12, and can also deflate the airbag ring 12 when it needs to contract. When inflation is not required, the hanging ring 10 can be directly hung on the hook 11 on one side of the grip 1;

[0030] Specifically, the fixing member further includes two groups of support rods 6 rotatably mounted on the surface of the fixing sleeve 5. Fixing holes 13 are formed in the surfaces of the two groups of support rods 6, and two fixing rods 14 corresponding to the fixing holes 13 are fixedly mounted on the surface of the fixing sleeve 5. The two groups of support rods 6 can be clamped and fixed through the two fixing holes 13 and the fixing rods 14. Vacuum stickers 7 are fixedly mounted at one ends of the two groups of support rods 6 away from the fixing sleeve 5, and the two groups of vacuum stickers 7 can be adsorbed and fixed on the patient's body by pressing;

[0031] Specifically, according to the puncture depth of the puncture needle body 2, the position height of its fixing sleeve 5, the airbag ring 12 and related components can be adjusted. At the same time, by rotating the two groups of support rods 6 and then pressing the vacuum sticker 7 at one end of the support rod 6, the vacuum sticker 7 is adsorbed and fixed on the patient's body, so that the two groups of support rods 6 can be used to support and fix the fixing sleeve 5 and the airbag ring 12, thereby preventing the puncture needle body 2 from shifting. And when it is not needed, the two groups of support rods 6 can be turned upwards, and then they can be respectively clamped to the fixing rods 14 by using the fixing holes 13 formed therein, so as to fix the two groups of support rods 6;

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
