Background
The thoracoscope is known as one of the major breakthroughs of the thoracic surgery field in the last century, and is a representative operation of the minimally invasive thoracic surgery. The thoracoscopic surgery (television assisted thoracoscopic surgery) uses a modern television camera technology and high-tech surgical instrument equipment to complete a minimally invasive thoracic surgery new technology of complicated operations in the chest under a chest wall sleeve or a micro incision, changes the treatment concept of some thoracic surgical diseases, is considered to be the most important progress of the thoracic surgery at the end of 20 th century, and is the development direction of the thoracic surgery in the future.
Through the retrieval, chinese patent number CN202011279043.X discloses a puncture ware for scalable antifouling type thoracoscope, including push rod and connecting block, the opposite side of push rod is provided with the pjncture needle, and the opposite side of pjncture needle is connected with outer body, the connecting block is installed in the both sides of outer body, and the opposite side of connecting block is connected with the handle, outer tube head is installed to one side of outer body, and the opposite side of outer tube head is connected with negative pressure joint, negative pressure joint's opposite side is connected with the negative pressure body, the opposite side of outer tube head is connected with screwed joint … …
The main technical problem that above-mentioned device solved is that the front of this product casing is installed flexible tube core, and the user can push away the pjncture needle of one side from outer body through promoting the push rod to push away flexible tube core through interior tube core, play the effect of adjusting length, prevent effectively through the lantern ring simultaneously that blood from flowing to the front end along the puncture ware, cause the blurred condition of the sight of thoracoscope. However, the postoperative pain is often strong and the pain of the patient is hard to endure due to the damage of intercostal nerves and the continuous irritation of the pleura caused by the postoperative indwelling thoracic drainage tube during the thoracic operation. Currently, paraspinal nerve block is the most classical and effective means of nerve block analgesia for thoracic surgery. Compared with the nerve blocking technology of indirect guidance such as body surface anatomical landmark positioning, ultrasonic positioning and the like, the paravertebral nerve blocking under the direct vision of thoracoscope guidance is easier to distinguish the structure of paravertebral clearance and is relatively more accurate. However, the problem that the depth of the puncture needle penetrating into the paravertebral gap cannot be accurately determined in the existing thoracoscope-guided descending paravertebral nerve block, the problem that the needle inserting depth of the puncture needle cannot be stably maintained in the process of injecting analgesic liquid medicine, the problem that the liquid medicine runs off through the gap between the puncture needle and the needle hole in the process of injecting the analgesic liquid medicine and the like often cause poor or even failure of the analgesic effect of the paravertebral nerve block. Moreover, when the paraspinal nerve block operation is conducted under thoracoscope guidance at present, a catheter cannot be placed in a paraspinal gap to a proper depth and fixed firmly, so that continuous postoperative analgesia can be achieved by continuously pumping and injecting analgesic liquid through the catheter.
