Abstract

The invention belongs to the technical field of medical instruments and particularly belongs to a dilating device for minimally invasive operations. The dilating device comprises a dilating component, dilating support strips, a positioning and fixing device and an elastic net, wherein the front ends of the dilating support strips are connected with the elastic net respectively to dilate the elastic net to be in an umbrella shape, and the tail ends of the dilating support strips are connected with the positioning and fixing device in a shrinkage mode. At least four dilating support strips are utilized to achieve the purpose of dilating the elastic net which is made of insulation materials. When the dilating device is opened, the abdominal wall and normal tissues below the dilating device are dilated, drooping tissues of the abdominal wall above the dilating device are pushed open, the tissues do not touch an endoscope lens, and a clear view is kept. Furthermore, the dilating device is simple in structure, convenient to operate and use and suitable for being popularized and applied in related technical fields.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a distraction device for minimally invasive surgery. Background technique [0002] At present, minimally invasive surgery such as endoscopy is becoming more and more popular. However, after the adhesions in the operation area are released or in the case of pneumoperitoneum, the surgical field of view is not displayed well. . Pneumoperitoneum surgery can cause carbon dioxide accumulation, hypercapnia, subcutaneous emphysema, air embolism and other complications. [0003] In general endoscopic surgery, the surgical site is not separated from normal tissue, and normal tissue is easily injured by needles and other instruments, and normal tissue is easily infected. Especially in tumor surgery, there is no isolation protection device between tumor and normal tissue, which is easy to lead to tumor growth. Contents of the invention [0004] The object of the present inve...
