Description

Technical Field

[0001] The present invention relates to the technical field related to positioning needles for thyroid surgery, and in particular to an auxiliary supporting device for positioning needles for thyroid surgery. Background Art

[0002] Under the guidance of ultrasound, the positioning needle used in thyroid surgery is used to accurately locate thyroid nodules in patients who have a strong desire for surgery before surgery. A retrospective study was then conducted on this technology to evaluate the safety and feasibility of this new positioning technology. The use of this positioning device in thyroid surgery is safe and reliable, has a high positioning success rate, can improve the diagnosis rate of thyroid diseases, and is also convenient for clinical surgeons to operate. It is a nodule precision positioning technology with certain clinical application value.

[0003] Existing thyroid surgery positioning needles use color ultrasound to mark nodules on the body surface to locate them, which has certain limitations. Since the skin and muscles need to be pulled apart to expose the surgical field of view, there will be an offset between the marked line and the actual nodule position. It is often difficult to accurately remove the nodule by comparing the color ultrasound image and the surface marking line to locate the nodule. In the actual process, the resection range is too large, resulting in excessive damage to normal thyroid tissue and causing hypothyroidism, or the resection range is too small, resulting in the nodule not being removed and being missed, leading to a secondary operation. Summary of the invention

[0004] The object of the present invention is to provide a positioning needle auxiliary support device for thyroid surgery to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A positioning needle auxiliary support device for thyroid surgery, comprising a protective tube, a puncture needle, a puncture rod and a puncture assembly, wherein the mounting position on the protective tube is provided with a puncture needle, the puncture position on the puncture needle is provided with a puncture rod, the movable position on the puncture assembly is provided with a protective tube and a puncture needle, and further comprising:

[0007] A pushing component, mounted on the puncture needle;

[0008] A positioning component, arranged on the puncture needle;

[0009] Wherein, a needle tube is provided at the mounting position of the puncture needle, and the needle tube and the puncture needle are protected by a protective tube set.

[0010] The positioning needle auxiliary support device for thyroid surgery as described above: the puncture needle passes through the protection tube and the inside of the needle tube.

[0011] The positioning needle auxiliary support device for thyroid surgery as described above: the pushing component includes a positioning line movably installed inside the puncture rod, and the positioning line passes through the puncture rod and the inside of the puncture needle.

[0012] The positioning needle auxiliary support device for thyroid surgery as described above: the pushing assembly also includes a pushing tube movably mounted on the puncture needle, and the positioning wire is movably mounted on the puncture needle through the pushing tube.

[0013] The positioning needle auxiliary support device for thyroid surgery as described above: the positioning component includes an anchoring positioning needle movably mounted on the needle tube, and the anchoring positioning needle passes through the interior of the needle tube through a positioning line.

[0014] Compared with the prior art, the beneficial effects of the present invention are: after positioning by the positioning line and the anchoring positioning needle, excessive damage to normal thyroid tissue due to excessive resection range in the actual process can be avoided to cause hypothyroidism; the positioning line and the anchoring positioning needle locate the range to prevent the resection range from being too small, resulting in the failure to resect the nodule and causing it to be missed, leading to a secondary operation; and the dye can be avoided from being stained to the thyroid tissue around the nodule, which is conducive to the precise staining of the thyroid nodule and the finding and resection of the nodule during surgery.

[0015] Pull the push tube completely out of the puncture needle, pull the positioning needle out of the body, and extend the positioning line from the skin surface as a mark. After successful positioning, a highlighted area can be displayed around the nodule with the help of color ultrasound images. After positioning, conventional thyroid open surgery is performed. Therefore, under the guidance of color ultrasound, the positioning line and anchor positioning needle are used to locate the thyroid nodule, so as to achieve the purpose of precise removal of the nodule.
