Description

Technical field to which the utility model belongs

The utility model relates to medicine, namely to devices used in surgery.

State of the art.

To analyze the effectiveness of the treatment of patients who have died from one cause or another, an autopsy is performed. When carrying out the autopsy of the bodies of the deceased, in addition to section knives, a surgical scalpel is used. The use of a scalpel allows for a layer-by-layer dissection of tissues, but a surgical scalpel, in contrast to a sectional knife, has a short blade and a short handle, which leads to a close position of the doctor's hand relative to the body to be opened.

In this case, the doctor's fingers may be injured on the sharp edges of the bones of the corpse.

To increase the accuracy and increase the pressure on the scalpel, the method of holding the scalpel in the "table knife" position is most often used, which differs from the first in that the index finger is placed on its dorsal surface in order to better fix the scalpel in the hand (Kovanov V.V. and et al. Operative surgery and topographic anatomy. M .: Medicine, 1995. - p. 208, fig. 127).

As a prototype used "Scalpel for incision of the skin and subcutaneous muscles in cattle" [RF patent for useful model No. 183477 dated 13.10.2017]. This device is a scalpel containing a handle connected to the cutting edge, characterized in that the cutting edge is made in the form of a flat figure - an isosceles triangle with a side-to-base ratio of 3: 1, which is separated from the handle by a shoulder whose area exceeds the area of the base isosceles triangle. Placing the index finger on the collar can provide precise blade positioning and reduce the risk of the index finger slipping off

However, the use of this device during a surgical operation is associated with a number of inconveniences:

1. The triangular shape of the blade does not allow using the scalpel for making precise cuts deep in the wound.

2. The presence of a collar makes it difficult to see the wound and manipulate in the depth of the wound, especially in obese patients.

3. The scalpel has an unusual shape and sharpening for surgery.

Disclosure of a utility model

The authors suggest

An autopsy scalpel with a protective cone, consisting of a blade (Fig. 1, position 2) and a handle (Fig. 1, position 5), fixedly connected, characterized in that at the transition of the blade to the handle, on the contralateral side from the sharpening area of the blade (Fig. 1, position 1) there is a conical thickening (Fig. 1, position 3), expanding from the blade to the scalpel handle, inside the conical thickening there is a cavity (Fig. 1, position 4) with a diameter of 10 mm and a depth of 10 mm, which ends blindly from the side of the blade and open from the side of the handle, the wall thickness of the cone-shaped bulge is 1 mm.

The device we offer has a number of advantages:

1. Protection of the terminal phalanx of the index finger of the doctor conducting the autopsy.

2. Convenience of positioning the sharpened area of the scalpel is due to the appearance of a stop for the surgeon's index finger.

3. Reducing the risk of the surgeon's index finger slipping off the scalpel due to the deep cavity of the cone-shaped thickening.

4. The scalpel has a simple shape, the cone-shaped bulge cavity has a wide entrance and is easy to wash and sterilize.

The technical result of using the proposed device is to protect the index finger of the doctor conducting the autopsy, while maintaining the accuracy of the positioning of the sharpening area of the scalpel blade and the possibility of applying the guiding force of the doctor's index finger during the incision.

To characterize the utility model, the following features of the device are used, in particular:

- at the point of transition of the blade into the handle, on the contralateral side from the sharpening area of the blade, there is a cone-shaped thickening,

- the cone-shaped thickening expands from the blade to the scalpel handle,

- inside the cone-shaped bulge there is a cavity with a diameter of 10 mm and a depth of 10 mm, which ends blindly from the side of the blade and is open from the side of the handle,

- the wall thickness of the cone-shaped bulge is 1 mm.

Brief Description of Drawings

FIG. 1 shows a diagram of the proposed device:

- position 1 - the area of sharpening the scalpel blade;

- position 2 - scalpel blade;

- position 3 - cone-shaped thickening;

- position 4 - the inner cavity of the cone-shaped thickening;

- position 5 - scalpel handle.

Implementation of the utility model

Example # 1

The claimed device can be applied as follows:

- The scalpel is taken in the hand, while the index finger lies in the inner cavity of the cone-shaped thickening (Fig. 1, position 4) and rests in it;

- Autopsy is performed on the sectional table;

- When a scalpel suddenly falls deep into the body, next to fragments or sawn edges of bones, the cone-shaped thickening takes the impact of potentially dangerous fragments or edges of the bones, pushes them apart and protects the end phalanx of the doctor's index finger.

- After autopsy, the scalpel is rinsed under running water and can be treated with any detergent or placed in a sterilizer without harming itself.

Claims (1)

An autopsy scalpel with a protective cone, consisting of a blade and a handle, fixedly connected, characterized in that at the point of transition of the blade to the handle, on the contralateral side of the sharpening area of the blade, there is a conical thickening, expanding from the blade to the handle of the scalpel, there is a cavity inside the conical thickening with a diameter of 10 mm and a depth of 10 mm, blindly ending on the side of the blade and open on the side of the handle, the thickness of the walls of the cone-shaped bulge is 1 mm.
