Description

one

This invention relates to a surgical technique, namely, probes for operations on the retroduodenal part of the common bile duct.

Probes containing a rod, a handle, and an olive with a groove are known.

The disadvantage of such probes is that the imposition of suprapapillary choledochoduodenal anastomosis does not exclude the possibility of dissection of the posterior wall of the common bile duct.

In order to prevent dissection of the posterior wall of the common bile duct during the imposition of the suprapapplular choledochoduodenal anastomosis, the proposed probe is equipped with a second olive with a transverse groove.

The drawing shows the proposed probe in three projections.

The proposed probe contains a flexible rod / stainless steel, a handle 2 and two olives 3 and 4} ia the end of the rod. Extreme olive 3 but in its form corresponds to the patella of the duodenal ulcer and consists of two parts: oblong with a longitudinal groove 5 and spherical. The elongated part can be provided with risks to control the incision length during sphycterotomy surgery. Chute 5 serves to cut the anterior steppe Vater papilla.

Behind the front olive 3 there is a second olpva 4 of semi-oval shape, having a transverse groove 6. Depending on the length of the narrowing of the distal part of the common bile

The second olive channel can follow the first olive at different distances (e.g., 5, 10, 15 mm), as a result, a set of probes with two olives at different mutual distances x can be used.

A probe with two olives is used on dilated biliary passages. An incision of the supraduodenal part of the common bile duct is made, and a curved probe is inserted through the choledocholithic orifice into the retroduodenal portion of the common bile duct and the duodenal papilla of Vateri. Oliva 3 is a projection guide for the location of the Vater papilla. Above it dissects the front

wall of the duodenum. A probe with two olives is pulled upwards, which allows the back wall of the duodenum and the front wall of the retroduodenal part of the common bile duct to be brought into the surgical wound. Depending on the pathologic findings, operations are performed on the papilla or retroduodenal part of the common bile duct. When performing sphincterotomy, the incision is made

along channel 5, which allows for a metered sphincterotomy and prevents dissection of the posterior wall of the Vater papilla. When suprapapillary choledochoduodenal anastomosis is performed, the incision is made over olive 4 along transverse groove 6, while the back wall of the common bile duct is not damaged and the dissection of pancreatic tissue is excluded, as the back wall of the duodenum is well palpated over the second olive. At the end of the operation, the probe is removed through the choledochotomic opening in the supraduodenal part, followed by closure of the anterior

the walls of the duodenum and choledochotomy hole in the supraduodenal part.

Subject invention

A probe comprising a stem, a handle and an olive with a longitudinal chute, characterized in that, in order to prevent dissection of the posterior wall of the common bile duct when superpapillary choledochoduodenostomy is applied, the probe is provided with a second olive with a transverse chute.
