Description
Technical Field
The invention relates to the field of endoscopic surgery equipment, in particular to a liposuction device for endoscopic breast surgery.
Background
When the breast diseases need to be treated by operation, the conventional breast operation needs to take an incision on the surface of a breast, and the incision with enough length is needed to expose the operation field so as to complete the operation under direct vision; the large incision, which is difficult to avoid, is a surgical problem that remains to be solved. Breast loss and certain surgical complications caused by surgery can affect the beauty of women and cause psychological damage. The endoscopic surgery is a minimally invasive surgery method developed from laparoscopic surgery, and is a necessary trend for the development of future surgery methods. The basic principle of the endoscopic surgery is to form a cavity inside the viscera, shoot the viscera on a monitoring screen, and operate surgical instruments outside under the monitoring and guiding of a high-tech display screen by an operator to perform operations such as exploration, electrocoagulation, hemostasis, tissue separation and incision, suturing and the like on diseased tissues. The medical instrument is a model of the application of high-tech technologies such as electronics, optics, camera shooting and the like in clinical operations, and has the characteristics of small wound, few complications, safety and quick rehabilitation.
The endoscopic breast surgery generally comprises a fat dissolving process, a fat sucking process, an endoscopic operation process, a specimen taking process, a flushing detection process and a drainage dressing process, wherein the fat dissolving process is to uniformly inject a fat dissolving liquid into a subcutaneous fat layer of an operation part, and the fat sucking operation is started at an interval of 10min after the fat dissolving liquid is injected. In the liposuction process, firstly, a trocar entering part marked before an operation is cut with the diameter of about 0.5cm, then a suction head with a side hole is inserted, and the liposuction is fully performed in a planned operation field under the negative pressure of 0.2-0.8 kPa. When subcutaneous fat suction is carried out, attention is paid to avoid that the side hole of the suction head directly faces the skin; the side hole of the suction head faces to the gland when the back clearance of the breast sucks the fat, and the side hole of the suction head faces to the axillary vein when the axillary fossa sucks the fat, so as to avoid violent operation. The existing liposuction device has a simple structure, needs to be operated to keep the orientation of the side hole, otherwise causes unnecessary injury to a patient, does not have a side hole deflection protection function, and therefore, the operation difficulty is increased and the operation risk is increased.
