Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a skin-line drawing device for amputation surgery. Background Art

[0002] During a surgical amputation, the doctor must first draw an arc on the skin of the patient's limb where the amputation is to take place. The arc must be symmetrical and meet curvature requirements. Currently, doctors generally draw lines based on experience and feeling. The arc drawn in this way is not symmetrical, and the curvature is irregular. Amputation according to such an arc will result in inconsistent skin lengths after amputation. When suturing the upper and lower skin, there will be difficulties in suturing the skin. If the suturing is forced, the sutured skin will be irregular, affecting postoperative recovery. In addition, amputation according to such an irregular arc will also result in uneven muscles after amputation. In order to cooperate with the skin suturing, sometimes it is necessary to remove excess muscles, resulting in a second operation. Summary of the Invention

[0003] The purpose of the present invention is to provide a skin line drawing device for amputation surgery, which can conveniently perform skin arc drawing operations before amputation surgery. The drawn arcs are accurate and regular, which is conducive to skin suturing after surgery.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A skin marking device for amputation surgery comprises a tape measure and an arc-shaped sheath, wherein the tape measure is marked with a length scale; the arc-shaped ruler is inserted into the arc-shaped sheath and can be extended and retracted along the arc-shaped sheath; the arc-shaped sheath and the arc-shaped ruler are both made of flexible materials; the closed end of the arc-shaped sheath is fixedly connected to the zero-scale end of the tape measure; the arc-shaped sheath faces the tail end of the tape measure, and the arc-shaped sheath and the tape measure form an L shape;

[0006] A first position-limiting stopper is provided on the inner wall of the opening of the arc-shaped sheath, and a second position-limiting stopper is provided on the bottom end of the arc-shaped ruler, and the first position-limiting stopper cooperates with the second position-limiting stopper.

[0007] The beneficial effects of the present invention are as follows: 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 a connecting line between the two points is determined, and then a vertical line of the midpoint of the connecting line is determined; the zero scale end of the tape measure is aligned with one of the dividing points, and then the arc ruler is pulled out to make the arc ruler extend and retract in the arc sheath, and the top of the arc ruler is aligned with the vertical line, and then a section of the arc of the upper section of the amputation site is drawn on the skin with a pen along the arc formed by the arc ruler and the arc sheath; then the zero scale end of the tape measure is aligned with another dividing point, another section of the arc of the upper section of the amputation site; and according to the above steps, two sections of the arc of the lower section of the amputation site are drawn; the four sections of the arc are drawn, and the arc drawing operation of the skin before the amputation operation is completed; the arc sheath and the arc ruler are used to make the drawn arcs accurate and regular, and the upper and lower sections of the amputation site are symmetrical, thereby facilitating skin suturing after the operation.

[0016] Combine Figures 1 to 3 As shown, the present invention provides a skin marking device for amputation surgery, comprising a measuring tape 1 and a curved sheath 2, the measuring tape being marked with length scales. A curved ruler 3 is inserted into the curved sheath 2 and can extend and retract along the curved sheath 2. Both the curved sheath 2 and the curved ruler 3 are made of flexible materials. The closed end of the curved sheath 2 is fixedly connected to the zero-scale end of the measuring tape 1. The curved sheath 2 is oriented toward the tail end of the measuring tape, forming an L-shape with the measuring tape. The curved sheath 2 and the curved ruler 3 are provided with angle scales.

[0017] A first position-limiting stopper 4 is provided on the inner wall of the opening of the arc-shaped sheath 2 , and a second position-limiting stopper 5 is provided on the bottom end of the arc-shaped ruler 3 . The first position-limiting stopper 4 cooperates with the second position-limiting stopper 5 .

[0018] Combine Figures 4 to 7 As shown, when using it, first use a tape measure to measure the circumference of the amputation site 6. Based on the circumference, use a pen to draw two points on the skin that divide the amputation site into upper and lower sections, namely points A and B. Points A and B divide the skin of the amputation site 6 into an upper section 7 and a lower section 8. Then, determine the connecting line C between the two points, and then determine the perpendicular line D at the midpoint of the connecting line. Align the zero-scale end of the tape measure 1 with one of the dividing points, in this case, point A. Extend the tape measure 1 along the connecting line C, then pull the curved ruler 3 so that it extends and retracts within the curved sheath 2, aligning the top of the curved ruler 3 with the perpendicular line D. Then, use a pen to draw an arc E on the skin along the arc formed by the curved ruler and the curved sheath. Then, turn the tape measure, align the zero-scale end of the tape measure with point B, and draw another arc F of the upper section of the amputation. Following this step, draw two arcs of the lower part of the amputation; draw four arcs to complete the arc drawing operation on the skin before the amputation surgery; use an arc sheath and an arc ruler to make the drawn arcs accurate and regular, and the upper and lower parts of the amputation site symmetrical, which is beneficial for skin suture after the surgery.

[0019] During the extension and retraction of the arc ruler 3 in the arc sheath 2 , the cooperation between the first limit stop 4 and the second limit stop 5 can prevent the arc ruler 3 from falling out, thereby limiting the arc ruler 3 .

[0020] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, utilize the methods and technical contents disclosed above to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
