Description

A skin line drawing device for amputation surgery

technical field

The invention relates to the technical field of medical devices, in particular to a skin line drawing device used for amputation surgery.

Background technique

In surgical amputation, the doctor needs to first draw an arc on the skin of the patient where the amputation is to be performed. The arc needs to be symmetrical up and down and meet the arc requirements. At this stage, doctors generally draw lines based on experience and feeling. On the one hand, the arc drawn in this way cannot be symmetrical up and down, and the arc is not regular. Following this arc of amputation results in inconsistent skin lengths after amputation. When the upper and lower skin is sutured, the problem of difficulty in skin suture will occur. If the suture is forced, the sutured skin will be irregular, which will affect the postoperative recovery. In addition, amputation according to this irregular arc will also result in uneven muscles from the amputation. In order to cooperate with the skin suture, it is sometimes necessary to remove the excess muscle, resulting in a second operation.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a skin line drawing device for amputation surgery, which can conveniently perform skin arc line drawing operation before amputation surgery, and the drawn arc line is accurate and regular, which is convenient for skin suturing after surgery .

The technical scheme adopted by the present invention to solve its technical problems is:

A skin line drawing device for amputation surgery, comprising a tape measure and an arc-shaped sheath, the tape measure is marked with a length scale; an arc-shaped ruler is inserted in the arc-shaped sheath, and the arc-shaped ruler can be extended and retracted along the arc-shaped sheath, The arc-shaped sheath and the arc-shaped ruler are both flexible materials; the closed end of the arc-shaped sheath is fixedly connected to the zero-scale end of the tape; the arc-shaped sheath faces the end of the tape, and the arc-shaped sheath and the tape form an L-shape;

The inner wall of the opening of the arc-shaped sheath is provided with a first limit stop, the bottom end of the arc-shaped ruler is provided with a second limit stop, and the first limit stop and the second limit stop are matched.

The beneficial effect of the present invention is that the circumference of the amputation site is measured by a tape measure, and two points that divide the amputation site into upper and lower sections are drawn on the skin with a pen according to the circumference; then the line connecting the two points is determined, and then the Draw out the vertical line at the midpoint of the connecting line; align the zero-scale end of the tape measure with one of the dividing points, then pull the arc-shaped ruler to make the arc-shaped ruler expand and contract in the arc-shaped sheath, and align the top of the arc-shaped ruler with the vertical Line, then use a pen to draw an arc line on the skin along the arc formed by the arc ruler and the arc sheath; then align the zero-scale end of the tape measure with another dividing point, and the other part of the upper part of the amputation. One arc; follow the steps above to draw two arcs at the lower part of the amputee; draw four arcs, and perform the arc drawing operation on the skin before the amputation operation; using an arc sheath and an arc ruler, The drawn arc can be made accurate and regular, and the upper and lower sections of the amputation site are symmetrical, thereby facilitating skin suture after surgery.

Detailed ways

1 to 3, the present invention provides a skin line drawing device for amputation surgery, including a tape measure 1 and an arc sheath 2, the tape measure is marked with a length scale; the arc sheath 2 is inserted with an arc The shape ruler 3, the arc ruler 3 can be extended and retracted along the arc sheath 2, and the arc sheath 2 and the arc ruler 3 are both flexible materials; the closed end of the arc sheath 2 is fixedly connected to the zero-scale end of the tape measure 1; The arc-shaped sheath 2 faces the end of the tape, and the arc-shaped sheath and the tape form an L-shape. The arc sheath 2 and the arc ruler 3 are provided with angle scales.

The inner wall of the opening of the arc sheath 2 is provided with a first limit stop 4, the bottom end of the arc ruler 3 is provided with a second limit stop 5, a first limit stop 4 and a second limit stop The stop 5 forms a fit.

Combined with Figures 4 to 7, when using, first measure the circumference of the amputation site 6 with a tape measure, and use a pen to draw two points on the skin that divide the amputation site into upper and lower sections according to the circumference, namely point A and point B. Points A and B divide the skin of the amputation site 6 into an upper segment 7 and a lower segment 8; then determine the connection line C between the two points, and then determine the vertical line D at the midpoint of the connection line; Aim at one of the split points, select point A here, place the tape measure 1 along the connecting line C, and then pull the arc ruler 3 to make the arc ruler 3 expand and contract in the arc sheath 2, Align the top with the vertical line D, and then use a pen to draw an arc E on the upper part of the amputation along the arc formed by the arc ruler and the arc sheath. Then turn the direction of the tape measure, align the zero-scale end of the tape measure with point B, and then draw another arc F of the upper part of the amputation part. According to this step, draw two arcs of the lower part of the amputation; draw four arcs, and perform the arc drawing operation on the skin before completing the amputation operation; using an arc sheath and an arc ruler can make the drawing The arc of the amputation is accurate and regular, and the upper and lower sections of the amputation site are symmetrical, which is convenient for skin suture after surgery.

During the expansion and contraction of the arc-shaped ruler 3 in the arc-shaped sheath 2, through the cooperation of the first limit stop 4 and the second limit stop 5, the arc-shaped ruler 3 can be prevented from coming out, and the arc-shaped ruler 3 can be prevented. Limiting effect.
