With the development of the endoscope technology, the endoscope is more and more widely applied to the thoracic and abdominal surgical operation. The operation is that the thoracic cavity and abdominal cavity of a patient are provided with operation incisions, the stable expansion of the operation incisions is maintained, and instruments are inserted into the body of the patient along the operation incisions to carry out corresponding surgical operation treatment; with the improvement of the minimally invasive concept and the development of the instrument technology, the number of the operation incisions needing to be formed in the endoscopic surgery is smaller and smaller, the precision of the instrument is higher and higher, and in practice, the instruments enter the same operation incision, and the body of a patient is observed through the endoscopic lens, so that high-precision operation is performed.
In the traditional chest and abdomen surgery, the operation incision expansion mode is to expand the operation incision through some metal draw hooks, which is more suitable for the application of the chest and abdomen surgery, when the method is adopted, the tissue damage caused by uneven drawing stress, effective incision exposure limitation and excessive drawing can be caused, and even the secondary damage to the incision can be caused; meanwhile, due to the traction mode, the tissues around the incision are not effectively protected, so that the tissues around the incision are possibly polluted and the tumor is possibly planted.
Based on the minimally invasive concept and the consideration of reducing secondary injury in the surgical process of a patient, at present, the disposable incision retractor which is made of flexible membrane materials and is supported by rigid upper and lower retractor rings to form a shape similar to a cylindrical sleeve gradually replaces the traditional incision expansion mode, and is widely applied to endoscopic surgery.
After performing the surgical incision, the surgeon places an incision retractor along the surgical incision and conforms it to the opening; under the action of the compression force of the incision wall muscle tissue, the flexible membrane material of the incision retractor can be tightly attached to the incision wall muscle tissue and maintain the stability of opening, and meanwhile, the possibility of pollution of the tissue around the incision and tumor planting is avoided.
However, due to the performance limitation of the membrane material, the middle part of the membrane channel of the incision retractor is inevitably compressed and reduced to form a channel which is inclined to an ellipse under the action of the compression force of the muscle tissue of the incision wall, and the channel opening is difficult to exhaust gas under the condition that a plurality of instruments enter from the same channel; the smoke generated when the energy instrument is used for tumor excision and other operations and the water vapor caused by the temperature difference inside and outside the thoracic cavity are difficult to be discharged from the passage port, so the operation visual field is influenced to a certain extent, and the air pollution of an operating room can be caused by the generation of waste gas; in order to solve the problem, the currently adopted mode is to place a suction tube into the body through an incision retractor channel and perform continuous negative pressure suction by a negative pressure exhaust source, but the larger suction tube usually occupies limited operation space and also obstructs the visual field of an endoscope; however, the smaller suction tube is difficult to meet the suction requirement, so how to select the suction tube and the corresponding placement position reasonably also becomes a factor to be considered before the operation, sometimes an additional operation incision has to be added for placing the suction, and this also causes unnecessary additional injury.
