Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of tractor, specifically relates to a laparoscope abdominal tractor of free pneumoperitoneum. BACKGROUND

[0002] Laparoscopic surgery is a new developed minimally invasive method, and is an inevitable trend of future surgical method development. With the rapid development of industrial manufacturing technology, the integration of related disciplines lays a solid foundation for developing new technology and new method, and in addition, the more and more skilled operation of doctors makes many past open surgeries be replaced by endo-laparoscopic surgery, thereby greatly increasing the surgical selection opportunity. The traditional method of retroperitoneal laparoscopic surgery is to make three 1cm small incisions on the waist of a patient, and then insert a pipeline-shaped working channel called "trocar" into each incision, and then all subsequent operations are carried out through the three pipelines; and then a specially designed lengthened surgical instrument is used to complete the same steps as open surgery under the monitoring of a television, so as to achieve the same surgical effect.

[0003] The advantages of two-hole retroperitoneal laparoscopic surgery are very obvious. Firstly, the trauma is very small, only two small openings are needed, and the scar is very small, which is more noticeable for young people and women who love beauty. Secondly, the operation is a direct and straight-through entry, and the damage to the surrounding tissue is minimized, and the chance of postoperative adhesion is small. Thirdly, the postoperative wound pain of the patient is significantly reduced. Fourthly, the hospitalization days are less, and some patients can be discharged in 2-3 days, and can completely recover health and return to work in 7 days, so that the patient's burden is greatly reduced, and the hospital bed turnover rate is accelerated.

[0004] The free-pneumoperitoneum laparoscope is based on the traditional laparoscope, and mechanical traction is used to replace CO2 pneumoperitoneum to expose the surgical field and complete the operation, so that the interference to the abdominal organs is small, the intestinal function recovers quickly after the operation, and the postoperative complications such as subcostal pain, subcutaneous emphysema and hemodynamic changes caused by pneumoperitoneum are greatly reduced. For some thin patients, patients with severe heart and lung function abnormalities or elderly patients, the traditional laparoscopic surgery has poor tolerance, the free-pneumoperitoneum surgery has no pneumoperitoneum stimulation symptoms, and the postoperative complications are greatly reduced. The free-pneumoperitoneum surgery has been widely used in appendicitis and intestinal surgery.

[0005] For some obese patients or patients with severe pelvic adhesion, the exposure of the surgical field is relatively difficult, and then the laparoscope abdominal tractor of free pneumoperitoneum is needed to open the surgical field. UTILITY MODEL CONTENT
