Problems solved by technology

In ERCP, the operation before and after papillary incision is performed with the support of the visualization system carried by the duodenoscope, which is a visual operation, but because the duodenoscope is thick, it can only reach outside the nipple , can not enter the nipple, so when the nipple is incised, when entering other instruments from the nipple for diagnosis or treatment, there is no support from the imaging system, and only rely on the contrast agent and X-ray to support the visual operation of the operation, so the follow-up operation is relatively difficult. It is not intuitive and clear enough, and the lesion cannot be directly observed to make a judgment

Embodiment 1

[0065] Such as Figure 1 to Figure 5 The shown medical device for minimally invasive interventional treatment of the pancreaticobiliary duct is specifically a visualized papillotomy knife, including a catheter 2, and the distal end 22 of the catheter 2 is provided with a surgical component—knife wire 61, The proximal end 21 of the catheter 2 is provided with an operating part for operating the knife wire 61—the operating handle 1 (including the sliding handle 11 and the handle seat).

[0066] Such as figure 2 As shown, the catheter 2 includes 4 main lumens, these 4 lumens are lumen 23, lumen 24, lumen 25, lumen 26, in this embodiment, the lumen 23 is a knife The wire lumen, the knife wire 61 fits with the lumen 23 in a gap and is fixedly connected with the end of the lumen 23, and the lumen 23 forms an opening at the end of the catheter 2, the proximal end of the knife wire 61 is fixedly connected with the sliding handle 11, slides The handle 11 can slide relative to the ha...

Embodiment 2

[0069] Such as Figure 6-11 The shown medical device for minimally invasive interventional treatment of the pancreaticobiliary duct is specifically a visualized papillotomy knife, including a catheter 2, and the distal end 22 of the catheter 2 is provided with a surgical component—knife wire 61, The proximal end 21 of the catheter 2 is provided with an operating part for operating the knife wire 61—the operating handle 1 (including the sliding handle 11 and the handle seat).

[0070] Such as Figure 7 As shown, the proximal end 21 of the catheter 2 includes 4 main lumens, and these 4 lumens run through from the proximal end of the catheter 2 to the distal end, and these 4 lumens are respectively the lumen 23 and the lumen 24. , lumen 25, lumen 26, the catheter 2 is provided with two auxiliary lumens 28 on the opposite side of the knife wire lumen 23. Such as Figure 6 As shown, the proximal end of the catheter is fixedly connected with the insertion tube 3, the insertion tu...

Embodiment 3

[0076] Such as Figure 12 to Figure 16 The shown medical device for the minimally invasive interventional treatment of the pancreaticobiliary duct is specifically a visualized stone removal balloon or dilatation balloon, including a catheter 2, and the distal end 22 of the catheter 2 is provided with a surgical component—a balloon 62 , The proximal end 21 of the catheter 2 is provided with operating components for operating the balloon 62—the operating handle 1 and the insertion tube 9 connected to the balloon control device (syringe) for inflating and deflated the balloon 62 .

[0077] Such as Figure 12 As shown, the catheter 2 includes a proximal end 21 and a distal end 22 , and the proximal end 21 is fixedly connected to the operating handle 1 . The insertion tube 3 , the insertion tube 4 , the insertion tube 5 and the insertion tube 9 communicate with the lumen 24 , the lumen 25 , the lumen 26 and the lumen 23 of the catheter 2 respectively.

[0078] Such as Figure 13...

Abstract

The invention discloses medical equipment of a micro-invasive interventional therapy for a pancreaticobiliary duct, which comprises a conduit, wherein the far-end of the conduit is provided with an operation part and the near-end thereof is provided with an operating part of the operation part; the conduit is at least provided with a visual orifice which can be passed through by a light pipe of an optical imaging system and a working orifice which can be passed through by an auxiliary instrument, and the visual orifice and the working orifice both pass through the near-end to reach the far-end; and the near-end of the conduit is provided with a plurality of insert tubes which are communicated with the visual orifice and the working orifice in a one-to-one correspondence mode. In the technical scheme, a visual orifice is added on the basis of ERCP medical equipment, thus not only realizing visualized operation diagnosis or therapy for the pancreaticobiliary duct, but also being simpler and having stronger technicality and lower cost compared with the endoscopic system structure. The medical equipment is disposable and the optical imaging system can be used repeatedly, thereby greatly lowering use cost and being convenient for operation manipulation.

Description

technical field [0001] The invention relates to the technical field of gastroenterology medical devices, in particular to a medical device for minimally invasive interventional treatment of pancreaticobiliary ducts, in particular to a papillotomy knife, stone removal balloon, expansion balloon, and stone removal basket. Background technique [0002] Endoscopic retrograde cholangiopancreatography (ERCP) involves inserting an endoscope into the descending segment of the duodenum, and after finding the large duodenal papilla, inserts a contrast tube through the forceps of the endoscope to the opening of the papilla, injects a contrast agent, and Cholangiopancreatography, bile bacteriology, biliary pressure and papillary sphincter function tests were performed. In addition, it can also be used for sphincterotomy (EST), bile duct lithotripsy, bile duct stent placement and drainage, nasobiliary drainage and biliary roundworm removal. It is mainly used to treat diseases such as lo...
