Description

[Technical field]

[0001] The invention belongs to the technical field of medical instruments, and in particular relates to a tool used in rhombus flap transfer surgery and a method of using the tool. [Background technology]

[0002] In the process of clinical medical diagnosis and treatment, the removal of inflammatory infection lesions such as pilonidal sinus and skin defects caused by trauma, burns, scars, etc. requires complete surgical removal of the skin and subcutaneous tissue. However, surgery often leads to a large area of ​​soft tissue defects. The use of flap repair is one of the most suitable methods. This method uses flap transfer to cover the exposed area after the removal of the inflammatory lesion. When the range of the inflammatory lesion increases, the free flap also needs to be increased accordingly. This method is suitable for patients with a wide range of lesions or postoperative recurrence. The traditional method is that it is difficult to suture directly after the lesion is removed, the wound is easy to tear, get infected, and even require a second operation; the use of bag-type sutures takes a long time to heal the wound, the patient's recovery is very painful, and it will leave a large scar. With flap transfer, as long as a reasonable surgical incision is taken during the operation, the size and shape of the transfer flap are designed to be consistent with the excised skin defect, the tension of the transfer flap wound suture is generally not too large, and the wound healing time is short; at the same time, because the transfer flap comes from the skin adjacent to the lesion, it matches the skin in the defect area in terms of color, texture, thickness and hair, so a good appearance and function can be obtained after surgery, and the patient satisfaction is high.

[0003] Therefore, in order to achieve the ideal effect of this operation, the design of the surgical incision and flap during the operation is extremely important. This requires the accuracy and precision of skin measurement and drawing. In the prior art, medical personnel use a ruler to measure and draw the shape of the area to be removed. Because the skin is elastic, multiple operations are prone to errors, inaccurate drawing, inconsistent shapes, and easily lead to the removal of too much normal skin tissue of the patient. The entire measurement and drawing process is cumbersome, inefficient, and inaccurate, which increases the difficulty of the operation. Therefore, it is necessary to design a measurement and drawing tool specifically for designing diamond-shaped flaps. [Summary of the invention]

[0004] The purpose of the present invention is to solve the above-mentioned problems and to provide a tool for diamond flap transfer and a method of using the tool to solve the problems of inconvenient operation and inaccurate measurement in measuring skin area and drawing in flap extraction surgery.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a tool for diamond flap transfer and a method of using the same, comprising a first measuring plate and a second measuring plate, wherein the first measuring plate is slidably connected to the second measuring plate, and a first scale and a second scale are provided on the side of the first measuring plate, wherein the first scale intersects with the starting end of the second scale, they are equal in length and have an angle of 120°.

[0006] The second measuring plate is in a diamond shape, and a third scale, a fourth scale and a fifth scale are arranged on the side of the second measuring plate. Two adjacent sides of the second measuring plate are the third scale and the fourth scale, and the fourth scale is parallel to the first scale. The angle between the starting ends of the third scale and the fourth scale is 120°, and their angle bisector is the fifth scale, and it is parallel to the second scale. A slot is opened on the second measuring plate along the fifth scale.

[0007] As a further optimization scheme of the present technical scheme, the measuring tool also includes a slot body and a slide plate, the slot body is fixedly connected to the side of the first measuring plate, the slide plate is fixedly connected to the side of the second measuring plate, and the slide plate is inserted in the slot body and can slide.

[0008] As a further optimization scheme of the present technical scheme, the trough body includes a first transverse plate, a second transverse plate and a connecting plate, the top end of the connecting plate is connected to the bottom surface of the first transverse plate, and the bottom end is connected to the top surface of the second transverse plate, so that a slide groove is formed between the first transverse plate and the second transverse plate, and the side surface of the second transverse plate is fixedly connected to the side edge of the first measuring plate; the slide plate is a square plate, one side of the slide plate is fixedly connected to the side surface of the second measuring plate, and the other side is inserted into the slide groove.

[0009] As a further optimization scheme of the present technical scheme, the side lengths of the first measuring plate are equal in height, the side lengths of the second measuring plate are equal to the total length of the first scale, and the lengths of the first horizontal plate and the second horizontal plate are equal to the side lengths of the first measuring plate.

[0010] As a further optimization scheme of the present technical scheme, the scale range of the first scale is 0-12 cm.

[0011] As a further optimization solution of the technical solution, through holes are provided on the first measuring plate and the second measuring plate, and a protrusion is provided on the second measuring plate.

[0012] As a further optimization solution of the present technical solution, the first measuring plate and the second measuring plate are both made of transparent plastic material.

[0013] As a further optimization solution of the present technical solution, a sixth scale is further provided on the side of the first measuring plate, and the scale range is 0-20 cm.

[0014] A method for using a tool for rhombus flap transfer surgery comprises the following steps:

[0015] Step 1: Slide the second measuring plate to the top of the first measuring plate, and then use the "0" endpoint of the first measuring plate to determine a point on the edge of the flap and mark it as point "A", so that the angle between the first scale and the second scale can enclose the flap;

[0016] Step 2: After determining point "A", take point "A" as the starting point, read the length of the flap on the first scale and the second scale respectively, take the maximum reading and mark the maximum reading as point "B";

[0017] Step 3: After determining point "B", if the reading on the first scale is the largest, find the position on the second scale that is the same as the reading on the first scale and mark it as point "C". If the reading on the second scale is the largest, find the position on the first scale that is the same as the reading on the second scale and mark it as point "C1".

[0018] Step 4: After determining the maximum reading, and determining the maximum reading on the second scale, start sliding the second measuring plate so that the reading on the fourth scale coincides (is the same as) the maximum reading taken on the second scale. After their readings are the same, mark the point "D" at the starting end point of the second scale;

[0019] Step 5: Read the point on the fifth scale that is the same as the maximum reading and mark it as point "E". Similarly, read the point on the third scale that is the same as the maximum reading and mark it as point "F".

[0020] Step 6: Finally, connect the six marked points according to ABDC (ABDC1) and BDFE, and finally obtain the figures of diamond ABDC (ABDC1) and diamond BDFE.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1: The flap measurement tool designed by the present invention is simple and convenient to operate, can quickly measure the minimum area, and effectively reduce the cutting of new skin of patients. Moreover, the tool is very effective in clinical use and greatly reduces the workload of medical staff.

[0023] 2: The tool first determines two adjacent sides of the damaged skin area through the first measuring plate, and then determines the other two sides through the second measuring plate. Since the side lengths of the first measuring plate and the second measuring plate are the same and the second measuring plate is a rhombus, the area finally determined is a rhombus, and the same rhombus can be drawn by connecting lines at the relative position of the damaged skin. Therefore, the same amount of new skin can be taken to transplant onto the damaged skin, reducing the amount of new skin removed from the patient.

[Specific implementation method]

[0031] The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.

[0032] Example

[0033] like Figure 1-3As shown, a tool for diamond flap transfer and a method of using the tool include a first measuring plate 1 and a second measuring plate 2, wherein the first measuring plate 1 is slidably connected to the second measuring plate 2, and a first scale 101 and a second scale 102 are provided on the side of the first measuring plate 1, and the starting ends of the first scale 101 and the second scale 102 intersect, are equal in length, and have an included angle of 120°, and specifically, the starting ends of the first scale 101 and the second scale 102 are on the symmetry line of the first measuring plate 1. The second measuring plate 2 is a rhombus plate, and the side of the second measuring plate 2 is provided with a third scale 201, a fourth scale 202 and a fifth scale 203. The adjacent two sides of the second measuring plate 2 are the third scale 201 and the fourth scale 202, and the fourth scale 202 is parallel to the first scale 101. The starting end angle between the third scale 201 and the fourth scale 202 is 120°, and their angle bisector is the fifth scale 203, and it is parallel to the second scale 102. A slot 204 is provided on the second measuring plate 2 along the fifth scale 203. The slot 204 is a trapezoid, and the slot 204 is used for drawing and drawing. More specifically, the third scale 201 coincides with the extension line of the symmetry line of the first measuring plate 1. The purpose of setting the starting end angle between the third scale 201 and the fourth scale 202 to 120° is to make their angle bisector equal to the length of the side of the second measuring plate 2. In addition, the lengths of the first scale 101, the second scale 102, the third scale 201, the fourth scale 202, and the fifth scale 203 are all set to be the same, and the framework diagram finally drawn is two symmetrical rhombuses, so that no deviation occurs during the flap measurement process.

[0034] Specifically, Figure 4As shown, the first measuring plate 1 and the second measuring plate 2 are both made of transparent plastic material. The tool also includes a slot body 4 and a slide plate 3. The slot body 4 is fixedly connected to the side of the first measuring plate 1, and the slide plate 3 is fixedly connected to the side of the second measuring plate 2. The slide plate 3 is inserted in the slot body 4 and can slide. The slot body 4 includes a first transverse plate 411, a second transverse plate 412 and a connecting plate 413. The top end of the connecting plate 413 is connected to the bottom surface of the first transverse plate 411, and the bottom end is connected to the top surface of the second transverse plate 412, so that a slide groove is formed between the first transverse plate 411 and the second transverse plate 412, and the side of the second transverse plate 412 is fixedly connected to the side of the first measuring plate 1; the slide plate 3 is a square plate. Specifically, in this embodiment, the slide plate 3 is a rectangular plate. One side of the slide plate 3 is fixedly connected to the side of the second measuring plate 2, and the other side is inserted in the slide groove. When the second measuring plate 2 is moved, the second measuring plate 2 will cover a part of the second scale 102. Therefore, the scale lines of the second scale 102 can be observed by using a transparent plastic material, which is convenient for reading. In this embodiment, the thickness of the second transverse plate 412 is the same as that of the first measuring plate 1. After the second transverse plate 412 is connected to the side of the first measuring plate 1, the slide groove is above the first measuring plate 1. In this way, the slide plate 3 is inserted in the slide groove to enable the second measuring plate 2 to slide freely on the first measuring plate 1.

[0035] In this embodiment, a sixth scale is also provided on the side of the first measuring plate 1, and its scale range is 0-20 cm. When the first measuring plate 1 is used to measure other objects, the sixth scale is used for measurement, and the first measuring plate 1 can be fully utilized. The scale range of the first scale 101 is 0-12 cm; the side lengths of the first measuring plate 1 are equal in height, the side lengths of the second measuring plate 2 are equal to the total length of the first scale 101, and the lengths of the first horizontal plate 411 and the second horizontal plate 412 are equal to the side lengths of the first measuring plate 1. In patients with pilonidal sinus, the flap length of the transferred skin flap required to repair the necrotic defect lesion is generally about 3-10 cm, so the scale range of 12 cm is designed to be sufficient to meet the daily work of medical staff.

[0036] In this embodiment, both the first measuring plate 1 and the second measuring plate 2 are provided with through holes 5, and the second measuring plate 2 is provided with a protrusion 205. The purpose of providing the through holes 5 is to facilitate hanging the tools when they are not in use; when measuring, the hand-pushing protrusion 205 can facilitate the sliding of the second measuring plate 2 on the first measuring plate 1.

[0037] A method for using a tool for rhombus flap transfer surgery comprises the following steps:

[0038] Step 1: Slide the second measuring plate 2 to the top of the first measuring plate 1, and then use the "0" end point of the first measuring plate 1 to determine a point on the edge of the skin flap and mark it as point "A", so that the angle between the first scale 101 and the second scale 102 can enclose the skin flap;

[0039] Step 2: After determining point "A", take point "A" as the starting point, read the length of the flap on the first scale 101 and the second scale 102 respectively, take the maximum reading, and mark the maximum reading as point "B";

[0040] Step 3: After determining point "B", if the reading of the first scale 101 is the largest, find the position on the second scale 102 that is the same as the reading on the first scale 101 and mark it as point "C". If the reading of the second scale 102 is the largest, find the position on the first scale 101 that is the same as the reading on the second scale 102 and mark it as point "C1".

[0041] Step 4: After determining the maximum reading, and determining the maximum reading on the second scale 102, start sliding the second measuring plate 2 so that the reading on the fourth scale 202 coincides (is the same as) the maximum reading taken on the second scale 102. After their readings are the same, mark the point "D" at the starting end point of the second scale 102;

[0042] Step 5: Read the point on the fifth scale 203 that is the same as the maximum reading and mark it as point "E". Similarly, read the point on the third scale 201 that is the same as the maximum reading and mark it as point "F".

[0043] Step 6: Finally, connect the six marked points according to ABDC (ABDC1) and BDFE, and finally obtain the figures of diamond ABDC (ABDC1) and diamond BDFE.

[0044] Through the above operations, it is finally concluded that the minimum skin area required for complete removal of the lesion is rhombus ABDC (ABDC1), and the new flap area is rhombus BDFE, and their symmetry line is BD. Since the lengths of the first scale 101, the second scale 102, the third scale 201, the fourth scale 202, and the fifth scale 203 are all the same, and the angle between the first scale 101 and the second scale 102 is 120°, the angle between the third scale 201 and the fourth scale 202 is 120°, and the fourth scale 202 is parallel to the second scale 102, the drawn rhombus ABDC (ABDC1) and rhombus BDFE are completely equal rhombuses, and the drawn figure is the minimum skin area required for complete removal of the lesion of the patient and the minimum area of ​​the required transfer flap.

[0045] The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
