technical field

The utility model relates to the technical field of medical devices, in particular to a disposable puncture sheath tube for thoracoscopic hand hyperhidrosis.

Background technique

Thoracoscopic bilateral sympathotomy is an effective method for the treatment of moderate to severe primary hyperhidrosis. Surgical methods have experienced 3-hole, 2-hole thoracoscopy and the single-hole technique commonly used so far, and the surgical methods and medical instruments have been improved. At present, the commonly used method in clinical practice is 5mm thoracoscopic single-hole method or double-hole method. The single-hole surgical procedure is as follows: the operator only needs to make an incision of about 8mm in the third intercostal space of the anterior axillary line of the patient's axilla, insert a 5mm thoracoscope, and then insert a 5mm electrocoagulation hook into the same hole. Under the guidance, the sympathetic nerve chain is located, and the sympathetic nerve chain is cut off by electrocoagulation on the surface of the third or fourth posterior rib, and the purpose of curing hand hyperhidrosis can be achieved, and the success rate is over 99%. The double-hole method is to make a 5mm incision in the anterior axillary line of the 3rd intercostal space to place a 5mm coagulation hook, and another 5mm incision in the midaxillary line of the 4th or 5th intercostal space to place a 5mm thoracoscope. Compared with the double-hole method, the single-hole method reduces one incision, which is easier for patients to accept for such a cosmetic surgery. Therefore, 5mm thoracoscopic single-port treatment of hand hyperhidrosis has now become routine. During the operation, the surgeon first needs to use a thoracoscopic trocar to pierce the chest wall to establish a surgical channel, and then put a thoracoscope and an electrocoagulation hook through the channel to complete the follow-up operation. The thoracoscopic trocar is mainly composed of a puncture sheath and a puncture needle. The surgeon first puts the puncture needle on the puncture sheath, and then acts on the tail of the trocar with a certain force. With the help of the sharp tip of the puncture needle, the puncture needle pierces the chest wall so that the entire trocar enters. The thoracic cavity is then withdrawn, leaving the puncture sheath as a surgical channel. In the single-port method, when a coagulation hook is inserted into the same surgical channel by means of a thoracoscope, the thoracoscope and the coagulation hook are prone to mutual interference, which affects the accuracy and safety of the operation. And sometimes artificial pneumothorax is required, that is, the trocar must have a sealing effect. Therefore, it is required that the puncture device can achieve the function of having mutually movable channels and simultaneously having the function of sealing gas.

The utility model provides support for reducing surgical incisions and trauma in thoracoscope surgery, and enables single-hole local anesthesia thoracoscopic surgery. However, the relative movement range of the tube body of the utility model is limited, which results in the limited movement of the thoracoscope and the electrocoagulation hook during the operation of the thoracoscope, which is inconvenient to operate, and the core cone at the front end is easy to operate during the insertion of the trocar into the chest cavity. Separation, the resistance increases, hindering the puncture of the trocar.
