The invention belongs to medical instruments, and in particular relates to a novel three-dimensional electronic choledochoscope system for reconfiguring a three-dimensional image by using a multi-CCD (Charge Coupled Device) array, which comprises a soft electronic choledochoscope, a processing host computer, a light source host computer and a work station assembly, wherein the processing host computer, the light source host computer and the work station assembly are connected with the soft electronic choledochoscope; the three-dimensional soft electronic cystoscope enters a gall bladder cavity through a small cut at the bottom of the gall bladder and can enter the biliary tract through a small cut on the bile duct wall, then turns into the bile duct through better flexibility and control,and then enters the common bile duct for detecting the condition of the common bile duct; the multi-CCD array module at the tip part of a choledochoscope working end part is used for finely scanning the common bile duct, even the intrahepatic bile duct to obtain a three-dimensional image of the choledochoscope cavity; and a doctor treats the gall bladder pathological change according to the three-dimensional image.

The invention discloses a bladder structure and a multilayer bladder system, the bladder structure comprising a plurality of walls defining a bladder cavity comprising an initial cross-sectional dimension. A first plurality of corrugated features is disposed along at least one of the plurality of walls defining the bladder cavity. In one arrangement, after the structure becomes expanded during curing of the composite charge, the first plurality of corrugated features allows the structure to expand from an initial cross-sectional dimension to a second cross-sectional dimension greater than Initial cross section size.

The invention relates to an antitumor drug containing lidocaine, which is prepared by dissolving lidocaine in a medically acceptable solvent, and the concentration of lidocaine is 1.25mg / ml-5mg / ml, or lidocaine The perfusion solution is made by combining with commonly used anti-bladder cancer perfusion drugs. The method of use is to use the above-mentioned medicinal solution immediately after preparation, pour the medicinal solution into the bladder cavity with a catheter, and keep the medicinal solution in the bladder cavity for 60-90 minutes before being discharged by itself. Lidocaine can directly inhibit tumor cells at a certain concentration, and the inhibitory effect is enhanced with the increase of drug concentration. When used in combination with anti-tumor drugs, lidocaine can enhance the anti-tumor effect of anti-tumor drugs, improve the anti-tumor effect of chemotherapy drugs, especially reduce the stimulating and toxic effects of chemotherapy drugs on the body during local drug treatment of tumors , reduce local pain, and improve the effect of tumor treatment.
