Abstract

The invention is intended to prevent injury to soft tissues and consists of t | = slab 1, stylet 2 with handle 3. The working ends of the stylet and tube are made in the form of a wedge 4 with an acute angle, the edge 5 of which is inclined at an angle of 40-50 ° to the forward axis. The fixation unit of the mutual arrangement of the tube and the stylet is made in the form of 2 strips 6 and 7, installed parallel to the edge 5 of the clip 4. 1 sludge. i (L cpual CO O CO CO

Description

The invention relates to medical technology and is intended for the fixed direction of auger during osteoperforation.

The aim of the invention is to prevent the trauma of soft tissue.

Figure 1 shows the proposed trocar, front view; figure 2 is the same, top view; on fig.Z - installation of a trocar on a bone; 4 shows a trocar tube fixed to the bone.

The trocar consists of a tube 1, a stylet 2 with a handle 3, the working ends of the stylet and the tube are jointly made in the form of a wedge 4, with an acute angle, the edge 5 of which is inclined at an angle of 40-50 ° to the longitudinal axis. The fixing unit of the mutual arrangement of the tube and the stylet is made in the form of 2 strips 6 and 7, installed parallel to the edge 5 of the wedge 4.

The trocar is used as follows.

A trocar with a sharp wedge 4 end is guided through soft tissues 8 to bone 9 and set obliquely with edge 5 of wedge 4 and slats 6 and 7 parallel to bone 9. Hammer the handle of edge 3 with sharp edge of wedge 4 into cortical bone 9. Stiletto 2 is removed from the tube 1, and through the fixed tube 1 with a drill (not

It was shown) using a drill or rotary drill, outflow of the pathological contents and washing of the bone cavity were performed directly through the tube 1, fixed with a bandage or adhesive plaster on soft tissues, or a soft irrigator was inserted into the bone marrow cavity.

The use of traocar does not require the dissection of soft tissues, eliminates the direct contact of the drill with soft tissues and traumatizing them, prevents the pathological contents from flowing into the wound and soft tissues and creates favorable conditions for shortening the treatment time. Traocar can be used in the practice of treating homotopic osteomyolitis in children.
