Abstract

BISTURI PEN. The present utility model patent relates to a scalpel pen (1) provided with a lighting element (2) accommodated inside the body (10), and facing the front end (12); and openings (4) around the opening (4) of the knife or needle exit (9) to exit the light in order to allow the surgery area to be illuminated, facilitating its visualization.

Description

BISTURI PEN

The present utility model patent relates to a scalpel pen, particularly used in minimally invasive surgeries.

Innovation History

The following exhibit, for simplicity of explanation, illustrates innovation within a particular embodiment, namely, a scalpel pen used with electric scalpels that is not restricted to electric ones only, and may be used in electronic, ultrasonic, bipolar, etc.

It is well known to man in the art to use electric razors to cut or cauterize parts of the human body. These devices are advantageously used because they reduce blood loss during surgery while incising the site.

The scalpel comprises a pen that is the object manipulated by the surgeon to perform the surgery. It is elongated, small, lightweight, ergonomic, and easy to handle. The pen has an opening at its front end through which the needle or blade is inserted for cauterization or cutting.

Whatever type of surgery the lighting should be adequate to allow a good view of the site.

It happens that the illumination of the place is usually above the operating table, being inefficient by the distance, structure and positioning of the surgeon, worsening when it comes to small incisions, ie minimally invasive surgeries.

In these situations it is common for the surgeon to use a light device around his head with the light turned to the patient, or to have the help of an assistant who secures a light source, directing it to the surgical site, as the surgeon requests. But none of these options is very appropriate, as the first situation requires the surgeon to constantly control the placement of his head relative to the workplace. In the second, the surgeon must indicate to the assistant at all times that he must maintain the lighting, which diverts his attention from the surgery.

In order to overcome these drawbacks, this innovation deals with a self-scaled scalpel pen that allows the treated site to be directly illuminated, improving the visualization of the surgery.

It is also an objective of the present innovation a scalpel pen which, by its direct illumination structure, makes it possible to optimize not only minimally invasive but also traditional surgeries.

It is also an objective of the present innovation with more efficient self-illumination iambisturi, as it illuminates the surgery site, giving the surgeon greater illumination accuracy, thus bringing surgical time gain, since there will be no need for central focus adjustment, as the The pen necessarily always points to the place where it is treated.

The reduction of the operative time, therefore, benefits the patient because it reduces their stay in the surgery, reducing the risk of contamination, reduced costs by reducing the time of use of the surgery, and also provides greater turnover in surgical centers.

The following are schematic figures of a particular realization of innovation, whose dimensions and proportions are not necessarily the real ones, as the figures are intended solely to present didactically the various aspects of innovation, the scope of which is protected solely by the scope of the appended claims.

Brief Description of Drawings

The following will be described based on our following designs:

Figure 1 illustrates a perspective view of the present scalpel pen (1);

Figure 2 shows an exploded, partially sectioned view of the scalpel pen (1) with LEDs (2) without its own key; and,

Figure 3 shows an exploded, partially sectioned view of the scalpel pen (1) with its own LED activation key (5) (2).

Description of illustrated configuration

The present utility model deals with a scalpel pen (1) provided with an elongated body (10) with an anterior end (11) for energy input and an opposite front end (12) of surgical tool (9).

As illustrated in figures 2 and 3, the body (10) accommodates within it a current generating plate (8), particularly waves, from which there is a surgical working tool, for example a knife or a needle (9). ), which protrudes out of the elongated body (10) through an opening (4), said knife or needle (9) cutting and / or coagulating.

The pen (1) comprises keys (6) and (7) which enable the scalpel plate (8) to coagulate or cut the site.

The scalpel pen (1) is characterized by being provided with a lighting element (2) accommodated inside the body (10), facing the working front end (12), and around the opening (4); and opening (3) around the aperture (4) to direct and allow light output.

Preferably, the lighting element is formed by one or more light-emitting diodes (LEDs) (2), which offer some advantages over conventional lamps, such as their small size, high efficiency, and low heat release.

As the LEDs (2) are internally positioned within the body (10), and the openings (3) are positioned around the tool opening (4) (9), the light necessarily exits the same direction as the tool (9). The LED provides illumination of an area of approximately 2 centimeters in diameter and its range is about 3 centimeters.

The activation of the LEDs (2) can be voluntary or automatic, being voluntary when the pen (1) comprises a key (5) exclusive to the LEDs (2), or automatic when the LEDs (2) are lit when the scalpel is turned on in its source. energy. This last situation is advantageously used when applying the LEDs (2) to a scalpel of the anterior part, taking advantage of the same existing electrical structure (see figure 2). In the situation where there is an exclusive key (5) for the activation of the LEDs (2), its control is the responsibility of the surgeon, who can choose the moment of its use.

The man of the art will readily perceive, from the description and drawings represented, various ways of accomplishing innovation without departing from the scope of the appended claims.
