Abstract

The embodiment of the invention provides an imaging catheter, a tip, a catheter body and a medical device, and relates to the field of medical instruments.The imaging catheter comprises the catheter body and the tip, wherein the catheter body comprises a first shuttling wall and a second shuttling wall; a first cavity is formed between the first shuttling wall and the second shuttling wall; the tip comprises a first mounting wall and a second mounting wall; a second cavity is formed between the first mounting wall and the second mounting wall; the second cavity is communicated with the first cavity; the near end of the first mounting wall corresponds to the position between the first shuttling wall and the second shuttling wall; and the radial distance between the m point and the n point is a, the inner diameter of the first cavity is b, and a is more than or equal to b, so that the fall is eliminated, and an instrument can enter the second cavity from the first cavity. The instrument compatible with the imaging catheter has a large outer diameter range, so that more types of instruments can enter the second cavity from the first cavity.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an imaging catheter, a tip, a tube body and medical equipment. Background technique [0002] The choledochal sub-scope system through duodenoscopy has gradually been recognized by the market. Studies have shown that compared with ERCP, the incidence of complications of the biliary sub-scope system has not increased, further confirming its safety. Compared with the traditional ERCP operation, the biliary mirror system observes the lesions and stones in the biliary tract through its own camera, which greatly improves the accuracy of the treatment of biliary tract diseases. When the biliary mirror system is used clinically, surgical instruments can be used through its working cavity to perform surgical treatment. However, there are fewer types of compatible surgical instruments in the existing working cavity. Contents of the invention [0003] Objects of the present invention incl...
