Abstract

The invention relates to a laparoscopic surgery lesion locating device. The laparoscopic surgery lesion locating device comprises an external pipe, an extending piece, a clamping bar and a traction handle; one end of the extending piece is connected with the traction handle, and the other end of the extending piece is connected with a rolling mechanism inside the external pipe; the end portion ofthe external pipe is provided with the clamping bar; the extending direction of the extending piece is distributed at 90 degrees relative to the axial direction of the external pipe; the extending piece is provided with scale marks ranging between 5 cm and 20 cm, the optimal length of the scale marks is 15 cm, and the accuracy of the scale marks is 0.5 mm or 1 mm; the external pipe is also provided with scale marks ranging between 5 cm and 20 cm, the optimal length of the scale marks is 10 cm, and the accuracy of the scale marks is 0.5 mm or 1 mm. The laparoscopic surgery lesion locating device has the advantages of being capable of precisely locating the position of lesions of organs and tissues and achieve three-dimensional space location, thereby achieving good locating effects particularly on relatively hidden lesions without obvious protrusions; meanwhile, the laparoscopic surgery lesion locating device can directly measure the size of the lesions and is high in measuring precision and simple in operation, thereby improving the surgical efficiency and safety.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a lesion locator used in laparoscopic surgery. Background technique [0002] As a common minimally invasive surgery, laparoscopic surgery has been rapidly popularized clinically in recent years. Laparoscopic surgery can replace traditional laparotomy in some specific occasions, relying on special surgical instruments to complete the surgical treatment of internal lesion tissue with smaller incisions. The damage is small and the postoperative recovery is fast, which benefits the patient a lot. [0003] In the prior art, the location of the lesions to be resected during laparoscopic surgery is determined by naked eye observation or blind detection. However, some lesions are located in the viscera and do not protrude obviously, so precise positioning cannot be achieved by naked eye observation. If the location of the lesion is located solely by naked eye observation or...
