Description

The present invention relates to medicine, namely to endoscopic surgery.

Expanding the capabilities of endoscopic surgery requires the creation of new devices that provide optimal opportunities for their use. Newer devices can help expand the capabilities of diagnostic and surgical endoscopy.

Inflammatory and neoplastic processes, as well as iatrogenic damage to the organs of the hepatopancreatoduodenal zone, are often associated with the occurrence of violations of topographic and anatomical landmarks and the development of deformations of duct structures. Modern methods of endoscopic diagnosis and treatment of diseases of the organs of the hepatopancreatobiliary zone require an expansion of the arsenal of devices for “difficult” catheterization of deformed ducts. To perform endoscopic catheterization of the deformed ducts, there are a number of devices.

Patent No. 23114013 C1 proposed an endoscopic “Device for the diagnosis and treatment of the pancreas” in the Federal State Pedagogical Center RCHFG, in which the catheter is equipped with a conical thread at the working end. Such a decision may complicate the passage into the ducts with significant bends and deformation.

The company Olympas in the Accessor catalog on page 46 proposed the working end of the catheter of the endoscopic device, with a bend by tensioning the thread, located in the endoscope next to the catheter and the applied measuring rings. The device can be taken as a prototype. Such a solution, when the end of the catheter is blunt and the thread is placed next to the catheter, can cause difficulty when passing through the deformed duct.

Such a device has disadvantages:

- it is difficult to install catheters in the deformed duct structures.

- there is no use of the rotation method of the gimlet.

The objectives of the invention are:

- providing catheterization of deformed duct structures using the rotation of the spiral tip and catheter with a bend and oblique cut in the workplace;

- expanding the possibilities of using minimally invasive surgery methods;

- providing the ability to supply solutions to duct structures.

The essence of the invention “Device for endoscopic catheterization of deformed duct structures” lies in the fact that in the catheter installed in the working channel of the endoscope, which has a bend and an oblique cut at the working end, a flexible rod with a spiral tip on the working side is fixed on the opposite side in the rod having a handle for rotary and longitudinal movements of the flexible rod in the catheter, which is installed in a sleeve with a handle for rotary and longitudinal movements of the catheter in the endoscope, and has a screw for fixing the rod to the sleeve, for joint movements of the catheter with a flexible rod, and also has a port for supplying solutions to the duct systems.

The device will provide:

- catheterization of deformed duct structures using the rotation of a spiral tip and a catheter with a bend and an oblique cut at the working end;

- the ability to supply solutions to duct structures;

- expanding the possibilities of using minimally invasive methods of endoscopic surgery;

Device design.

The design of the device shown in the drawing, where Fig.1 is a General view; figure 2 is a section along aa.

In the endoscope 1, a catheter 2 with a bend 3 and an oblique cut 4 at the working end is installed.

A flexible rod 5 with a spiral tip 6 is installed in the catheter 2. The flexible rod 5 is fixed with a screw 7 to the rod 8 with a handle 9 installed in the sleeve 10 with a handle 11, a screw 12 and a port 13 for supplying therapeutic solutions to the duct 14.

The operation of the device is as follows:

On the working side, a flexible rod 5 with a spiral tip 6 is installed in the catheter 2 with a bend 3 and an oblique cut 4, and the catheter 2 is installed in the endoscope 1.

On the opposite, working side, a sleeve 10 with a screw 12 and a port 13 for supplying therapeutic solutions is connected to a catheter 2. A rod 8 is installed in the sleeve 10, a flexible shaft 5 is inserted into it and fastened with a screw 7.

The spiral tip 6 is inserted into the catheter 2, and the catheter 2 is inserted into the endoscope 1. The endoscope 1 with the catheter 2 is mounted to the duct 14. The spiral tip 6 and the catheter 8 are displaced by the handle 9.

For joint movements of the catheter 2 and the spiral tip 6, the rod 8 is attached to the sleeve 10.

Using the handle 10, rotary and longitudinal movements of the spiral tip 6 are performed, and with the help of the distal end of the catheter 2 with a bend and oblique cut, deformed ducts are catheterized with subsequent supply of therapeutic solutions to the duct systems 14 through the connection port 13.

At the end of the intervention, the following are installed: a spiral tip 6 in the catheter 2, and a catheter 2 with a bend 3 and an oblique cut 4 in the endoscope 1. Endoscope 1 is removed from the intervention zone.
