(54) TIPS FOR SUCTIONS

one

The invention relates to medical technology and is intended to illuminate the operative field when conducting surgery, for example, on the larynx and pharynx.

A known tip to the aspirator, comprising a coaxially arranged light guide tube and an aspiration tube with holes in the wall located in the immediate vicinity of the end face of the light guide 1.

A disadvantage of the known device is the low illumination of the surgical field and the need to periodically clean the end of the fiber, which increases the operation time.

The purpose of the invention is to improve the illumination of the operating floor and reduce the time of surgery.

This goal is achieved by the fact that in the device containing a light guide tube and an aspiration tube, the end of the aspiration tube is located at a distance of at least five diameters of the said tube from the end of the light guide, and the holes in the wall of the aspiration tube are angled to the end of the light guide. Moreover, the aspiration tube is made with a vorn-like expansion at the working end.

Figure 1 shows the tip to the aspirator, General view; in Fig.2, view A in Fig. 1) in Fig. 3 is a section B-B in Fig. 1.

The device contains coaxially arranged light guide tube 1 and aspiration tube 2. Moreover, the end face,

The tube 2 is located at a distance of at least five diameters of this tube from the end of the light guide 3, and the holes in the wall of the tube 2 are angled to the end

5 | Light guide 3. The aspiration tube 2 is made with a funnel-shaped extension at the working end 4.

The device works as follows.

0

When applying the flushing liquid to the output end of the light guide 3, it is necessary to block the opening at the working end 4, for example, cut it to the fabrics.

five

When operating in the aspirg mode, liquid is sucked from the output end of the fiber. Tilt the beater on the generatrix of the working end simultaneously with the cleaning of the exit end

0 fiber eliminates the suction of the end to the tissues in the operating area. The working end is made easily removable, which provides ease of sterilization by any known method, while the tip with fiber optic cable cannot be sterilized, but only allows disinfection or wiping due to the special properties of the glass.

Thus, the proposed | Tip to the aspirator at the expense of making holes along the generator of the working tip in the immediate vicinity of the output end of the fiber oblique reduces the operation time by 15-20 minutes due to the effective cleaning of the output end of the fiber, and this reduces blood loss the patient "a 0, 5 l ..:

Claims (2)

1. A suction head tip containing a coaxially arranged light guide tube and an aspiration tube with openings in the wall in close proximity to the end of the light guide is characterized in that, in order to improve the illumination of the surgical field and shorten the time, the end of the suction tube is located on a distance of at least five diameters of said tube from the end of the light guide, and the holes in the wall of the suction tube are angled to the ends of the light guide. 2. A tip to an aspirator according to claim 1, characterized in that the aspiration tube is made with a funnel-shaped extension at the working end.
