Description

The utility model relates to medical equipment for performing surgical operations, in particular endoscopic ones, and can be widely used when performing surgical operations from small accesses using high-intensity laser radiation.

A device for intracavitary coagulation, comprising a probe with channels for a fiber, for the removal and supply of clarifying fluid, a flexible rod with coagulating electrodes and a hydrodynamic system for pumping and aspirating the clarifying fluid, the device is equipped with a rod for bending the distal end of the probe, and a flexible rod with the coagulating electrode is made with a spring-loaded distal end (ed. St. USSR No. 466022, M. cl. A 61 n 3/04, publ. 04/05/1975).

The known device provides the supply of the coagulating electrode to any part of the cavity, and also provides a synchronous supply and suction of clarifying fluid with the moment of supply of the coagulation pulse.

However, the known design is quite complex structurally and in operation.

A device for diathermocoagulation is known, containing a probe in the form of a polymer tube with an opening at the end, in the channel of which with the possibility of longitudinal movement there is an insulated flexible metal rod with an electrode at the end, as well as an aspiration system in communication with the probe, the electrode being made with a thickening, the rod is preliminarily curved, provided with elastic elastic polymer threads fixed perpendicular to its soybeans and installed with a gap in the probe channel connected directly the aspiration system (see. auth. binding of USSR №2641298, M. cl. A 61 B 17/36, publ. 15.04.1991 g).

According to its creators, the well-known design can reduce trauma during intracranial interventions.

As the material of the probe in the known device uses a polymeric material. A flexible element for performing thermal action is a metal rod bent at the working end and containing fixed on it at the same end

elastic polymer fibers forming a coarse mesh with a diameter corresponding to the inner diameter of the polymer tube. The purpose of this element is to eliminate clogging of the suction channel (gap) at the level of the end of the polymer tube with clots that exceed the inner diameter of the tube.

The known device is designed to perform diathermocoagulation when performing mainly neurosurgical interventions.

When using this well-known tool when exposed to VILI on the operated organ, it loses its design features, since the fiber placed in the probe does not provide the probe with a rigid bend of the working end, since the fiber material is not rigid.

Thus, the known device cannot be used when performing surgical interventions using VILI.

A device for conducting elastic probes, selected as the closest analogue, containing a hollow handle connected to the tube, a hollow rod, the hole of which communicates with the hole in the handle, while the distal

part of the handle has a channel and a recess in communication with the channel, and the proximal part is equipped with a removable cover, the tube is screwed into the bottom, inserted with its other end into the channel of the distal part of the handle (ed. No. 207358, M. cl. 30 k, publ. 12/22/1967).

This device allows you to facilitate the operation of the device.

However, it remains difficult both constructively and in operation. In particular, this known tool is difficult to manufacture and time-consuming to process, due to the large number of articulated elements.

It does not have a channel for suctioning the liquid and gases generated during processing by laser radiation in the affected area. Due to the fact that a handle is used as a holding device, the holding of this known tool is more intense.

Thus, the technical result, the solution of which is claimed by the claimed utility model, is the creation of a surgical instrument for supplying a flexible element to the operated organ when performing operations from small accesses, which is simple structurally, easy to use and allows

perform operations using high-intensity laser radiation.

The specified technical result is achieved by the fact that in the known surgical instrument for supplying a flexible element to the operated organ when performing operations from small accesses, containing a hollow rod equipped with an element for holding it in the hands and performed by a radially bent working section, in the through channel of which there is a gap and with the possibility of longitudinal movement, a flexible element is located, according to a utility model, inside the rod with a gap to its inner walls, an additional rigid hollow A fixed tube, in which a flexible element is located, which is used as a light guide leading laser radiation to the place of impact, and the element for holding the instrument in hands is made in the form of two eyelets for fingers located on two opposite sides on the outer surface of the main shaft.

The instrument is supplied with an additional hollow tube located motionless inside the hollow rod with a gap to its inner surface and the location of the flexible

element provides, which is used as a fiber, leading the laser radiation to the site of impact, precisely due to the presence of a gap between the tube and the rod, provides the possibility of suction of liquid and combustion products generated during the operation from the exposure area

The implementation of the element for holding the tool in the form of two eyes, located on opposite sides on the outer surface of the main hollow rod further greatly facilitates the holding of the claimed tool in the hand, significantly reduces the tension of the hand when holding it. This in turn improves the performance of the claimed design.

The inventive utility model is illustrated by drawings.

Figure 1 shows a schematic diagram of the inventive tool (side view); figure 2 is a schematic diagram of a tool (side view).

A surgical instrument for supplying a fiber to an organ to be operated upon when performing operations from low access using high-intensity laser radiation contains a hollow rod 1, the working end of which is made curved along the radius R.

The hollow rod 1 has a through channel 2. In this channel 2 there is an additional hollow tube 3 installed in the main rod 1 motionless with a gap with respect to the inner walls of the rod 1. A flexible element is located in the hollow tube 3 with a gap - the light guide 4. The light guide 4 has the ability to carry out movement in the longitudinal direction. The light guide 4 is fed into the hollow tube 3 by means of a rigid hollow element 5 located in the lower non-working part of the tool, cut into the wall of the hollow rod 1 from the outside

At the end of the hollow rod 1, opposite the worker, there is an element for holding the tool in hands. This element consists of two eyes 6, located on opposite sides on the outer surface of the main hollow rod 1.

The tool works as follows.

An optical fiber 4 is inserted into the inner hollow tube 3 through the hollow rigid element 5, with the help of which laser radiation acts on the organ to be operated.

A device for suction and vacuum aspiration of liquid and combustion products) (not shown) is connected to the hollow rod 1.

Through small access, the tool is brought to the point of impact strictly at a right angle, which cannot be done with a tool with a straight channel execution. The laser radiation source is turned on and the organ being treated is processed while the combustion products and liquids are removed from the exposure zone. The suction is carried out in the gap between the inner surface of the rod and the outer surface of the tube. Manipulation of tools is carried out by holding the tool with fingers inserted in the eyes 6.
