Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a three-color marked pulmonary nodule positioning needle. Background Technique

[0002] Thoracoscopic resection of pulmonary nodules has been widely used clinically due to its minimally invasive and safe advantages. However, the volume of pulmonary nodules is small, and the thoracoscopic field of view is limited. Therefore, before the operation, under the fluoroscopy of CT, puncture positioning technology must be used to accurately position the pulmonary nodules to help the surgeon find the pulmonary nodules during the operation, so as to improve the accuracy of the operation. The original positioning needle is composed of a spring nickel wire, a connecting tube and a suture. Before use, the spring nickel wire and the suture need to be connected through the connecting tube, which not only makes the assembly process of the positioning needle tend to be complex, but also has potential safety hazards of unreliable connection.

[0003] Therefore, a pulmonary nodule positioning needle with the publication number of "CN220069819U" includes a puncture needle. The puncture needle is used to push the positioning needle to position the pulmonary nodules. One end of the puncture needle is provided with a puncture needle handle, and a push hole communicating with the puncture needle is arranged on the puncture needle handle. A push rod is inserted into the push hole, and one end of the push rod inserted into the puncture needle pushes the positioning needle through a push inner core assembly. When in use, first place the positioning needle into the front end of the puncture needle. After puncture is completed through the puncture needle, hold the push handle and insert the push rod into the puncture needle through the push hole. The push rod pushes the inner core part to slide in the puncture needle, drives the limit slider to slide in the sliding hole, and the inner core part pushes the positioning needle out of the puncture needle. The threaded spring part at the front end of the puncture needle is inserted into the pulmonary nodule to complete the positioning of the pulmonary nodule. With the integral structure of the puncture needle, it can actually bear strong pulling force and is not easy to fall off during positioning, having a good positioning effect.

[0004] However, for the above pulmonary nodule positioning needle, although the inner core part pushes the positioning needle out of the puncture needle and the threaded spring part at the front end of the puncture needle is inserted into the pulmonary nodule to complete the positioning of the pulmonary nodule, the following obvious defects still exist during the use process: the depth of the lesion needs to be determined through the puncture needle, recorded and the data retained, while the above positioning needle can only perform puncture positioning of pulmonary nodules, but cannot visually mark the depth of the human lesion position with the positioning needle. Content of the Utility Model

[0005] The purpose of the utility model is to provide a three-color marked pulmonary nodule positioning needle to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A three-color marked pulmonary nodule positioning needle, including:

[0008] A sealed push tube is sleeved on one end of the outside of the puncture needle. The inside of the puncture needle is provided with a push inner core for positioning and pushing the positioning needle for puncturing the lung nodules.

[0009] Preferably, a puncture push handle is provided at one end of the puncture push rod located outside the puncture needle seat, which can enable the puncture push rod to push the puncture needle in a directional manner to perform puncture work, thereby ensuring the accuracy of puncture.

[0010] Preferably, one end of the pushing inner core is provided with a positioning hole groove for pushing and positioning the puncture needle, and the other end of the pushing inner core is provided with a positioning hole, which can enable the puncture needle to maintain its position during the pushing process, so as to facilitate more accurate puncture into the lung nodule.

[0011] Preferably, a sterile clamping rubber ring is provided inside the positioning hole groove, and the end of the puncture needle is inserted into the positioning hole groove and clamped and positioned by the sterile clamping rubber ring, so that the puncture needle is always kept in the center position of one end of the pushing inner core during pushing.

[0012] Preferably, the positioning needle is inserted into a positioning hole provided at one end of the push-pull inner core for positioning, and the length of each color marking line at the end of the positioning needle is 3 cm to ensure that the positioning needle accurately punctures the lesion in the lung nodule during pushing.

[0013] Preferably, both ends of the inner cavity of the sealing push tube are embedded with sealing rubber rings, and the sealing push tube is sleeved on the surface of the puncture needle and clamped and sealed by the sealing rubber ring, which can ensure the sealing between the sealing push tube and the puncture needle.
