A multifunctional pulling device for minimally invasive treatment of gastrointestinal tumors

technical field

The invention relates to the technical field of minimally invasive surgical devices, in particular to a multifunctional pulling device for minimally invasive treatment of gastrointestinal tumors.

Background technique

Minimally invasive treatment methods for gastrointestinal stromal tumors, including laparoscopic surgery, gastroscopic surgery, and colonoscopic surgery, can be considered for laparoscopy if the volume is not very large, and there are no severe intra-abdominal adhesions and no serious cardiopulmonary diseases. Minimally invasive surgical treatment, resection of gastrointestinal stromal tumors, small trauma, fast recovery, minimally invasive treatment of gastrointestinal tumors refers to the use of special instruments to complete tumor resection under the guidance of a monitor, on the patient's abdominal wall Make a few holes, then put the cannula in through the small hole, and then perform laparoscopic surgery through camera observation. This kind of surgery has relatively little trauma to the body. It is well-recognized, and the surgical incision is small, the damage is small, and the recovery after the operation is fast, so it is called minimally invasive surgery. Minimally invasive surgery can generally ensure that the tumor is removed completely and avoid subsequent adverse reactions of patients.

Existing minimally invasive surgery for gastrointestinal tumors is currently widely carried out in many hospitals at home and abroad. At present, this type of surgery requires general anesthesia. Stretching reactions in gastric surgery and intraoperative vomiting and reflux are difficult to solve with semi-systemic anesthesia. , this type of operation is relatively safer under general anesthesia, the patient is safe and painless, and there will be no subsequent adverse reactions. During the operation, it is necessary to use a traction rope to pull the affected tissue so that the surgical instruments entering the human body will not The operation is affected by the obstruction and hindrance of the body tissues on both sides, but the existing pulling rope is usually pulled manually or the rope end fixing sleeve is placed on the storage hanging rod to wind the pulling effect, which cannot be adjusted due to the position during the operation. Adjust the angle of the pulling rope at any time, and it is impossible to quickly store the too long pulling rope at any time, resulting in cumbersome angle adjustment operations and problems affecting the surgical process. Therefore, it is urgent to design a multifunctional minimally invasive gastrointestinal tumor Therapeutic stretching devices are used to solve the above problems.
