The aim of the invention is to reduce trauma in the diagnosis of patency and localization of the papillary canal, papillosphincterotomy and papillosphincteroplasty.

The probe contains an orienting part 1, a working part connected to it with stepped elements 2, whose diameter is successively increased in the direction of the orienting part, a handle 3, a graduated elastic catheter 4 with a mandrel 5. The elements 2 of the working part are made elastically, tubular, coaxially crossed equal in length. The orienting part 1 is made hollow, fastened with the element 1 of the working part, which has the largest diameter, and has pavilion 6 with an elastic membrane 7 at its free end. mi, with the possibility of longitudinal movement. One of the elements 1 of the working part has side holes 8. The catheter 4 has a cannula 9. The elements 1 of the working part have different colors, such as green, white, blue and black. The elastic elements 1 are made in the form of plastic tubes with a diameter of 3-4, 5-6-8 mm and a length of 3 cm, smoothly melted. The tubes are tightly inserted one into the other.

 in a hot condition and rigidly connected to the flexible metal orienting part 1. The catheter 8 has a diameter of 1.2-1.5. Elastic elements

5 2, put it on the orientation 1, the left part 1, are bent so that they repeat the course of the distal common bile duct from its suproduodenal part to the Fater papilla.

10 A catheter 4 is passed through the membrane 7, its working end is the thinnest element with a variable length. Through the catheter 4, antispasmodic agents, contrast agents can be administered.

After the operation on the Fater papilla and the return of the catheter 4 to the canal of the working part, all solutions can be injected with the syringe into the cavity of the pavilion, 20 perforated membrane 7.

Working with the probe for the common bile duct is described as follows.

After opening the abdominal cavity, 25 conducting revisions, performing cholicystectomy, intraoperative cholangiography is performed. With the presence of concrements in the choledochus, they are carefully removed through the supraduodenal choledochotomy. The probe end of the working part is passed through the choledochhotomic hole into the lumen of the terminal part of the common bile duct, either slightly forward or backward. If the end of the working part of 3 mm in diameter does not pass through the duodenal papilla into the lumen of the duodenum without the slightest resistance and vypiva- 40 or papilla, then. through the pavilion membrane push graduated cate31

ter. When it appears in the lumen of the duodenal cot, groping through its front wall determines the approximate location of the Vater papilla. If only half of the graduated end of the catheter is penetrated into the intestinal lumen, there is either tubular papilla stenosis or concrements in the papillary canal. After opening the anterior wall of the duodenum and dissecting

The Vater papilla without stretching, bulging or dislocating it, which causes pancreatic tissue injury, removes the graduated catheter and flushes the fluid through the membrane with a syringe and flushes out the choledochus through the round through holes in the middle segment of the working part of the probe. small stones, putty masses and films. After the revision of the Wirsung duct, the wounds of the duodenum and the choledochus are sutured, leaving the necessary drainage.

A probe for the common bile duct reduces the probability of probing, prevents complications, BbmiaeT reliably determines the localization of the Vater papilla, the common bile duct, the presence of stenosis and its length, reduces damage to the pancreatic tissue and facilitates opera

papillosphincterotomy and papillosphincteroplasty,

Claims (2)

1. A probe for the common bile duct, containing a flexible orienting part, a working part connected to it with stepped elements, whose diameter is successively increased in the direction of the orienting part, so as to reduce injuries in the diagnosis of patency and localization of papillary canal, papillosphincterotomy and papillosphincteroplasty, it is equipped with a handle and a graduated elastic catheter with mandrin, the elements of the working part are made elastic, tubular, coaxially hidden captive, equal in length, the orienting part is made hollow, fastened to the element of the working part having the largest diameter, and has a pavipion with an elastic membrane at the free end, while the handle is attached to the orienting part, the catheter is placed in the through channel formed by the orienting and working parts, with the possibility of longitudinal movement, and one of the elements of the working part has side holes. 2. The probe according to claim 1, except that the elements of the working section have different colors.
