Description

A pilot pin that is used for pulmonary nodule thoracoscope preoperative

Technical Field

The utility model belongs to the technical field of medical equipment, concretely relates to a pilot pin before pulmonary nodule thoracoscope operation.

Background

With the importance of people on health physical examination and the popularization of low-dose spiral CT, pulmonary nodules are more and more common, and the discovery rate of the pulmonary nodules can reach about 25%. For lung nodules with malignant consideration, consensus and guidelines recommend early surgical resection to achieve the goal of radical treatment and long-term survival. The pulmonary nodule is very little, and how quick, accurate location of operative person finds the pulmonary nodule and excises when thoracoscopic operation is the key, otherwise can cause open chest operation, enlarge events such as operation excision scope, consequently, utilizes the location to carry out preoperative location to the pulmonary nodule, and operative person is according to quick, the accurate pulmonary nodule position of discernment of pilot pin, carries out accurate, little wound excision, and furthest protection patient's pulmonary function shortens the operation time. In the prior art:

(1) methylene blue localization: methylene blue is a medical staining agent, and the pulmonary nodule in vivo is positioned by a method of guiding methylene blue injection staining through CT, and the defect is that the methylene blue has high dispersion speed, and a clinician is often required to perform thoracoscopic surgery within 3h after injection positioning, which has certain influence on the arrangement and connection of the surgery. On the other hand, the lung resection range is enlarged due to the characteristics of easy diffusion and easy interference, so that the lung surface positioning area is enlarged, the operation visual field is polluted, and the lung resection range is enlarged.

(2) Medical glue positioning method: the essence of the adhesive is that the adhesive is prepared by taking alpha-n-octyl cyanoacrylate as a main adhesive and adding polymethyl methacrylate. When encountering micro anionic substances, such as blood, body fluid or tissue fluid in human body, the medical adhesive can be rapidly polymerized at room temperature, solidified into a film and tightly embedded with the contacted tissue surface to achieve the purpose of positioning. The defect is that the medical gel is industrially synthesized, has certain pungent smell, and can enter the trachea along with the breathing of a patient to cause irritable cough, accompanied with chest pain and pneumothorax.

(3) Hook-wire localization: hook-wire is also called a special positioning needle for mammary gland, is firstly used for preoperative positioning of a mammary nodule and then extends to preoperative positioning of a pulmonary nodule. The defect is that the lung is greatly influenced by the respiration of the lung, and the unhooking, the displacement and even the dislocation are easily caused, thereby causing serious adverse events.

(4) Microcoil positioning method: the microcoil is an embolization material for blood vessels, and is used for positioning pulmonary nodules by utilizing the fact that cilia of the microcoil coagulate after contacting body fluid and blood. The defects are that the micro spring ring has small volume and soft texture, is difficult to touch and find by an operator, is expensive, and is easy to unhook like Hook-wire.

(5) Disposable lung nodule dedicated locator needle (proximal): a preoperative positioning needle suitable for a pulmonary nodule thoracoscope comprises a puncture needle and an anchoring positioning needle, wherein the anchoring positioning needle comprises 4 hooks with anchors and a positioning line. The puncture needle is not sharp enough, the focus under the pleura is not easy to penetrate the pleura, and the operation fails and falls off the pleural cavity; too many 4 hooks with anchors are easy to cause the patient to lift lung tissue and to cut blood vessels and tissues to cause hematoma; the position of the positioning needle can not be positioned when the positioning needle falls off the chest wall without developing under the X-ray of the positioning line, thereby causing adverse events; the length of the positioning needle is only 10cm, and the length of part of patients with special body positions is not enough, so that the positioning can not be completed.
