Magnetic-mediated pulmonary lobe traction tongs

Abstract

The invention discloses a pair of magnetic-mediated pulmonary lobe traction tongs, which comprises pulmonary lobe traction tong heads, a joint, a spring steel plate, connecting lines, a traction block and an in-vitro traction magnet. The instrument, by controlling the bending and the unbending of the spring steel plate at the tail end, can close and open the traction tong heads; and under the magnetic actions of the in-vitro traction magnet and the traction block, traction on the pulmonary lobe traction tongs is achieved. Through magnetic mediation between an in-vitro part and an in-vivo part of the instrument, pulmonary lobe traction can be achieved without additional chest wall incision, and a single chest wall operating hole can not be occupied, so that mutual interference of instruments is avoided; in another aspect, the instrument can flexibly adjust a pulmonary lobe traction angle through the connection of the traction block and the connecting lines and can adjust traction strength by adjusting the magnetic force of the in-vitro traction magnet, so that an operative field is fully exposed; therefore, the pair of the traction tongs is more beneficial for a surgical doctor to smoothly complete single-hole thoracoscope.

Description

technical field [0001] The present invention relates to minimally invasive surgical instruments, in particular to magnetically mediated minimally invasive instruments Background technique [0002] Video-assisted thoracoscopic surgery (referred to as "thoracoscopic surgery") refers to a new technique of minimally invasive thoracic surgery that completes complex intrathoracic surgery through several tiny incisions on the chest wall. Compared with traditional thoracotomy, thoracoscopic surgery has obvious advantages such as less surgical trauma, less postoperative pain, faster postoperative recovery, and fewer complications. Surgery and core business, thoracoscopic lobectomy and mediastinal lymph node dissection have become the standard surgical procedures for lung cancer surgery. [0003] At present, conventional thoracoscopic lobectomy requires three small holes on the chest wall, including an observation port, a main operation port and an auxiliary operation port. The main...

Problems solved by technology

However, due to the reduction of incisions, all the operating instruments come in and out through this port. This method has the following disadvantages: 1. There is mutual interference between instruments, and there are often situations where other instruments cannot enter or move after one instrument enters; 2. , Because the single incision is small, it is often impossible to insert the oval forceps to pull the lung lobes, and some surgical areas are poorly exposed

3. The instruments enter through one direction, and a stable operation triangle cannot be formed, which makes it difficult for surgeons who are familiar with traditional three-incision thoracoscopic surgery to complete single-port thoracoscopic surgery; The bottleneck of surgical development, there is an urgent need to develop new minimally invasive surgical instruments that can solve the above problems
