RU48747U1 - Backlight tweezers - Google Patents

Abstract

The utility model relates to medical equipment, in particular, to surgical instruments and is designed to work in dark places of deep wounds and cavities of the body. The tweezers contain an autonomous power source and LEDs with a switch. The difference of the proposed invention is the ends of the branches, bent at an angle of 120 ° -130 °, LEDs arranged in a special way, which provides illumination of the surgical field and an autonomous power source. This design of tweezers allows you to use it with or without light, and it also provides shadowless illumination of the surgical field and the captured anatomical structure, which in turn provides more comfortable working conditions for the surgeon.

Description

The utility model relates to medical equipment, in particular, to surgical instruments and is intended to perform surgical interventions.

Tweezers of various designs have long been used in medicine. Among them, a large group are surgical and anatomical tweezers without backlight.

The closest technical solution adopted for the prototype is surgical tweezers with straight jaws and without LEDs (see "Surgery and topographic anatomy"; edited by academician of the Russian Academy of Medical Sciences V.V. Kovanov; publishing house "Medicine", 2001 , pp. 220-221.)

The disadvantages of the prototype is the inability to work with him in deep wounds and various cavities of the body without light. As a result of this patient, it is necessary to turn to the main light source in the operating room, to supply additional light sources or to expand the boundaries of the wound or cavity for greater light access.

The objective of the utility model is to improve the quality and comfort of the surgeon during complex surgical interventions.

The problem is solved in that the tweezers containing two spring jaws are additionally equipped with an autonomous power source, two LEDs located on the outside of the jaw and a light switch, the jaws bent at an angle of 120 ° -130 °. The tweezers can optionally be equipped with a third LED located at the junction of the branches along the inner central axis of the tweezers.

To clarify the utility model proposed drawings.

Figure 1 shows a General view of the tweezers, with open branches and off LEDs;

figure 2 shows a General view of the tweezers in the operating position with the LEDs on and a schematic representation of the direction of light;

figure 3 shows a view of the tweezers from the side (from the outside);

figure 5 - tweezers with a central and side LEDs in the idle position;

figure 6 - tweezers with three LEDs in the working position and a schematic representation of the direction of light;

Fig.7 shows an electrical diagram of tweezers with three LEDs.

Illuminated tweezers contain a platform for attaching a power source (1), a replaceable power source of various capacities (battery or accumulator) (2), insulated conductors of electric current to LEDs (bulbs) or optical-fiber-glass conductors (3), ribbed jaws circuit breaker (5), LEDs (6) and tweezers branches having a bending angle of about 120 ° -130 ° (7).

All elements of the electric circuit are isolated from the external environment by special polymers that allow sterilizing the tweezers by boiling methods or in UV rays.

Tweezers work as follows.

After isolating the anatomical structure and grasping it with jaws of forceps, the surgeon closes the circuit with the switch with the index finger, thereby lighting up the LEDs, which allows further work without additional light devices in a deep wound or cavity. Due to the autonomous power source, it is not necessary to connect additional wires to it, which ensures more comfortable work of surgeons without foreign objects, and tweezers can also be used as a normal surgical one.

Thus, the proposed utility model allows you to quickly and accurately identify the anatomical structure in the wound or cavity of the body without the use of additional light devices.
