Description

Single-hole thoracoscope operation line passing device

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a line ware is crossed in haplopore thoracoscope operation.

Background

With the progress of minimally invasive endoscopic technology and the improvement of instruments, single-hole thoracoscopic surgery has become a conventional operation mode of thoracic surgery lung surgery, mediastinum surgery and the like. Blood vessel ligation, one of the most commonly handled procedures, requires a filament to be passed around the blood vessel for the subsequent ligation operation. At present, when blood vessels cross lines in a single-hole thoracoscopic operation, two modes exist: the first is to use long endoscope bending forceps to clamp the silk thread, pass through the blood vessel from the lower part, then release the silk thread by loosening the long bending forceps, and then use the same long bending forceps to clamp the head end of the silk thread and draw the silk thread out of the thoracic cavity. The second is to use a long curved clamp to clamp the silk thread, pass under the blood vessel, then use another long curved clamp to clamp the end of the silk thread, release the first clamp at the same time, and then draw the silk thread out of the thoracic cavity.

Both of the above two approaches have certain drawbacks: 1. in the first mode, the silk threads are easily taken out together in the process of releasing the long bending pliers and withdrawing the pliers, so that the threading failure is caused; 2. in the second mode, two long bending tongs enter the thoracic cavity through the same hole for operation, so that the two long bending tongs are inevitably collided to cause operation difficulty; 3. in the two methods, the tearing of the silk thread to the blood vessel wall cannot be avoided in the process of pulling the silk thread, so that the blood vessel wall is easily damaged, and unpredictable intraoperative hemorrhage is caused; 4. because the distance between the blood vessel to be ligated and the chest wall incision is often longer, the silk thread is easy to adhere to the peripheral tissues such as lung, so we propose a single-hole thoracoscope operation thread guide to solve the above mentioned problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems that in the prior art, the long curved tongs are easy to be taken out together with silk threads in the process of releasing the long curved tongs and withdrawing the tongs, which leads to the failure of threading, two long curved tongs enter the thoracic cavity through the same hole for operation, and inevitably lead to the collision of the two long curved tongs and the operation difficulty, in the process of drawing the silk threads, the tearing of the silk threads to the vascular wall can not be avoided, the vascular wall is easy to be damaged, and unpredictable intraoperative hemorrhage is caused; the thread passing device for the single-hole thoracoscope surgery is provided due to the defects that the path of a blood vessel needing to be ligated is often longer from a chest wall incision, and a thread is easily adhered to peripheral tissues such as lungs.
