Description

Technical Field

[0001] The utility model relates to the technical field of lung nodule positioning needles, and more specifically, to a lung nodule positioning needle. Background Art

[0002] With the development of imaging diagnostic technology, the discovery of early lung lesions has become easier and earlier, and the detection rate of small lung nodules that require surgical treatment has also become easier and easier. Generally, preoperative positioning is performed when removing lung lesions less than 1 cm in size, that is, the small lung nodules are located by percutaneous puncture under CT guidance; preoperative positioning often uses a positioning needle, and the metal wire with a positioning hook at the end is used as a positioning anchor. The existing positioning mechanism is made of hard materials and is easy to cause damage to human tissue.

[0003] After searching, the Chinese patent with announcement number CN215739332U discloses a "pulmonary nodule positioning needle". The metal wire of this utility model is made of nickel-titanium alloy. The densely wound gold wire of the nickel-titanium alloy makes this metal wire more flexible and can effectively protect human tissue. The tail is connected with nylon wire, which makes the lesion easier to locate and less likely to shift, causing less damage to the human body, bringing convenience to thoracoscopic pulmonary nodule resection.

[0004] When the above patent is in use, the end of the push rod is connected to a push handle, and the end of the puncture needle extends into and is fixed in the puncture needle handle. However, when pushing, it is inconvenient to control the moving distance of the push rod, and the push rod is easy to shake, resulting in poor use effect. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a lung nodule positioning needle, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lung nodule positioning needle, comprising a shell, a needle tube and a push pin, and one end of the needle tube is fixedly connected to the shell, one end of the push pin passes through the shell and the needle tube, a slider is movably arranged inside the shell, and one side of the slider is fixedly connected to the push pin, and the other side of the slider is fixedly connected to a side block, a plurality of second card blocks are fixedly connected to the side block, a plurality of first card blocks are fixedly connected to the front and rear sides of the shell, and a positioning component is provided inside the needle tube.

[0007] Furthermore, the positioning assembly includes a positioning wire and a positioning line. The positioning line is located on a side of the push pin away from the slider, and the other end of the positioning line is fixedly connected to the positioning wire.

[0008] Furthermore, a push plate is fixedly connected to the top of the sliding block, and the top of the push plate passes through the top of the shell.

[0009] It can be seen that in the above technical solution, it is convenient to push the slider to move horizontally.

[0010] Furthermore, two limit plates are fixedly connected to the front and rear sides of the inner part of the shell, and one side of the four limit plates extends into the slider.

[0011] It can be seen that in the above technical solution, the four limit plates can prevent the slider and the limit plate from deflecting.

[0012] Furthermore, the needle tube is made of polypropylene material.

[0013] It can be seen that in the above technical solution, transparent material is used to facilitate observation of the position of the positioning component.

[0014] Furthermore, the positioning wire is a component made of memory metal material.

[0015] It can be seen that in the above technical solution, it is convenient to restore to a hook shape.

[0016] Furthermore, the positioning line is a component made of polyvinyl alcohol.

[0017] It can be seen that the above technical solution has good biocompatibility, has no irritation or toxic reaction to human tissue, and is not prone to cause allergies or infections.

[0018] Technical effects and advantages of the utility model:

[0019] The utility model can drive the slider to move horizontally in the shell by pushing the push plate, thereby driving the push pin to move horizontally, and pushing the positioning wire into the needle tube through the push pin, and at the same time the slider drives the side block to move horizontally. Since the multiple second clamping blocks are engaged with the multiple first clamping blocks, there will be an obvious sense of frustration when pushing the push plate. At the same time, the multiple second clamping blocks cooperate with the multiple first clamping blocks to make the shell and the slider engage. The structure is simple, and it is convenient to control the moving distance of the push pin. At the same time, the push pin is not easy to shake, and the use effect is good.
