Description

Technical Field

[0001] The utility model relates to a skin surgery auxiliary tool, in particular to a rhombus flap surgery auxiliary positioning and marking device. Background Art

[0002] Currently, in clinical practice, different transfer flaps are often used to repair larger skin defects in order to fill the wound and reduce tension.

[0003] For diamond flap surgery, a diamond-shaped cutting line will be marked on the excised skin area, and then two cutting paths for the transferred flap will be drawn next to the excised area.

[0004] In actual surgery, doctors usually need to mark the flap transfer path or direction on the patient's skin with their bare hands. The length and angle of this freehand cutting path are difficult to be very accurate, which may lead to inaccurate selection of flap incisions, and too much normal skin needs to be trimmed later, which is not conducive to healing. Utility Model Content

[0005] The purpose of the utility model is to overcome the problem of low accuracy of drawing a cutting path on the patient's skin by hand during diamond flap surgery, and to provide an auxiliary positioning and marking device for diamond flap surgery, which can assist the doctor in determining the length and position of the cutting path.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a rhombus flap surgery auxiliary positioning and marking device. The rhombus flap surgery auxiliary positioning and marking device comprises:

[0007] handle,

[0008] A leg mounted on the bottom of the handle;

[0009] A first auxiliary rod, the head end of which is mounted at the bottom of the handle, and the length of which is adjustable;

[0010] A second auxiliary rod, wherein the head end of the second auxiliary rod is mounted on the tail end of the second auxiliary rod;

[0011] The supporting legs, the first auxiliary rod and the second auxiliary rod are in the same plane, and the handle is perpendicular to the plane where the supporting legs, the first auxiliary rod and the second auxiliary rod are located.

[0012] Preferably, the supporting leg comprises two left and right support rods, and the angle between the two support rods is adjustable.

[0013] Preferably, two leg rotating shafts are arranged at the bottom of the handle, and the head ends of the two support rods are rotatably mounted on the two leg rotating shafts respectively.

[0014] Preferably, the head end of the support rod is provided with an arc-shaped gear plate, and the gear plates of the two support rods are meshed with each other; the gear plate is provided with a first angle scale line, and the support leg shaft is provided with a first pointer pointing to the angle scale line.

[0015] Preferably, the first auxiliary rod is rotatably mounted on the bottom of the handle.

[0016] Preferably, the head end of the first auxiliary rod is provided with a rotating sleeve, and the rotating sleeve is sleeved on the bottom of the handle; the sleeve is provided with a set screw, and the tail end of the set screw presses against the handle.

[0017] Preferably, the handle is provided with a second angle scale line, and a second pointer is provided on the rotating sleeve to point to the second angle scale line.

[0018] Preferably, the head end of the second auxiliary rod is rotatably mounted on the tail end of the first auxiliary rod, a third angle scale line is arranged at the tail end of the first auxiliary rod, and the second auxiliary rod is provided with a third pointer, which points to the third angle scale line.

[0019] Preferably, the second auxiliary rod comprises a telescopic sleeve and a telescopic sleeve rod slidably sleeved in the telescopic sleeve; the telescopic sleeve is connected to the handle, and the telescopic sleeve rod is connected to the second auxiliary rod.

[0020] Preferably, the telescopic sleeve rod is provided with length scale lines.

[0021] Preferably, the legs, the first auxiliary rod and the second auxiliary rod are flush with the ground.

[0022] The application of the above technical solution of the utility model has the following effects:

[0023] When in use, the supporting legs, the first auxiliary rod and the second auxiliary rod are arranged closely against the patient's skin, and the handle is perpendicular to the patient's skin.

[0024] The handle is used for the doctor to grasp and install the supporting legs, the first auxiliary rod and the second auxiliary rod. The handle itself does not play a role in marking.

[0025] On one hand, the legs support the handle on the patient's skin to prevent the handle from shaking. On the other hand, the legs are in a fixed position relationship with the rhombus resection part (for example, the legs are pressed on the edge of the rhombus resection part or the legs are pressed on the extension line of the cutting line of the rhombus resection part). The position and angle of the handle can be determined by the legs, thereby determining the position and angle of the first auxiliary rod and the second auxiliary rod.

[0026] According to the arrangement of the excision site and flap cutting line before the operation, the length of the first auxiliary rod is adjusted in advance and fixed; when the cutting line needs to be drawn during the operation, after the position of the supporting legs is determined, the position and length of the first auxiliary rod and the second auxiliary rod can be determined, and the line can be drawn along the first auxiliary rod. At the same time, the angle of the second auxiliary rod can also be determined.

[0027] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The specific implementation of the present invention is described in detail below. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0040] In the present invention, unless otherwise stated, the directional words such as "upper" and "lower" usually refer to the orientation in the assembled state. "Inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0041] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the utility model described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0042] The utility model provides a rhombus flap surgery auxiliary positioning and marking device, comprising a handle 1, a support leg 2, a first auxiliary rod 3, a second auxiliary rod 4 and the support leg 2.

[0043] The supporting leg 2 is installed at the bottom of the handle 1. The head end of the first auxiliary rod 3 is installed at the bottom of the handle 1, and the length of the first auxiliary rod 3 is adjustable. The head end of the second auxiliary rod 4 is installed at the tail end of the second auxiliary rod 4. The supporting leg 2, the first auxiliary rod 3 and the second auxiliary rod 4 are in the same plane, and the handle 1 is perpendicular to the plane where the supporting leg 2, the first auxiliary rod 3 and the second auxiliary rod 4 are located.

[0044] like Figure 6 As shown in , the main function of the device of the present application is to determine the position, length and position of DE. In practice, the cutting length of EF will be determined according to the tightness of the skin after the flap is pulled during the operation. Therefore, here we only need to determine the starting point and direction of EF. In actual use, align the bottom of the handle 1 (equivalent to the head end of the leg 2) with the Figure 6 The middle position is D. The leg 2 can be pressed on the edge of the rhombus cut-out part ABCD, that is, the two sides AD and CD. It can also be on the reverse extension line of the two sides AD and CD. After the position of the leg 2 is determined, the first auxiliary rod 3 corresponds to the DE line, and the second auxiliary rod 4 corresponds to the EF line.

[0045] The length of the DE line will change according to the size of the rhomboid resection site ABCD. Therefore, the length of the first auxiliary rod 3 can be adjusted and fixed, and after the rhomboid resection site ABCD is determined before surgery, the length of the DE line is already determined. Therefore, the length of the first auxiliary rod 3 will be adjusted in advance before use.

[0046] like Figure 1-4 As shown in , the support leg 2 includes two left and right support rods 2a. The two support rods 2a facilitate the determination of the position and angle of the handle 1. At the same time, the angle of the rhombus resection part ABCD itself also needs to be adjusted according to the actual surgical situation. Therefore, the angle between the two support rods 2a is adjustable.

[0047] like Figure 2 and Figure 3 As shown, two leg shafts 1a are provided at the bottom of the handle 1. The head ends of the two support rods 2a are rotatably mounted on the two leg shafts 1a. The head ends of the support rods 2a are provided with arc-shaped gear plates 2b, and the gear plates 2b of the two support rods 2a mesh with each other. Figure 4 As shown, the above technical solution can be used to adjust the angle of the support rod 2a in advance to ensure that the angle α and the angle β are always equal and the middle axis remains stationary.

[0048] The gear plate 2b has a first angle scale line, and the leg rotating shaft 1a has a first pointer pointing to the angle scale line. The angle between the two support rods 2a can be read through the first angle scale line and the first pointer.

[0049] like Figure 2 As shown in the figure, the first auxiliary rod 3 is rotatably mounted at the bottom of the handle 1. The first end of the first auxiliary rod 3 is provided with a rotating sleeve 3c. The rotating sleeve 3c is sleeved at the bottom of the handle 1. The sleeve is provided with a set screw, and the tail end of the set screw presses against the handle 1.

[0050] The handle 1 has a second angle scale. The rotating sleeve is provided with a second pointer pointing to the second angle scale. By setting the second angle scale and the second pointer, the positional relationship between the first auxiliary rod 3 (line DE) and the supporting leg 2 (diamond ABCD) can be determined.

[0051] The head end of the second auxiliary rod 4 is rotatably mounted on the tail end of the first auxiliary rod 3. A third angle scale line is set at the tail end of the first auxiliary rod 3. The second auxiliary rod 4 is provided with a third pointer. The third pointer points to the third angle scale line. The angle relationship between the second auxiliary rod 4 (line EF) and the first auxiliary rod 3 (line DE) is determined by the above settings.

[0052] Specifically, the second auxiliary rod 4 includes a telescopic sleeve 3a and a telescopic sleeve rod 3b slidably sleeved in the telescopic sleeve 3a. The telescopic sleeve 3a is connected to the handle 1. The telescopic sleeve rod 3b is connected to the second auxiliary rod 4. The telescopic sleeve rod 3b has a length scale line. The outer end of the telescopic sleeve 3a can serve as a pointer.

[0053] Only when the supporting leg 2, the first auxiliary rod 3 and the second auxiliary rod 4 are all close to the patient's skin, the marking operation is convenient. Therefore, the bottom surfaces of the supporting leg 2, the first auxiliary rod 3 and the second auxiliary rod 4 are flush.

[0054] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0055] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0056] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
