One-shaped minimally invasive wrinkle removal dissector with equal perimeter of the head rod part

Abstract

The present invention provides a linear minimally invasive wrinkle removal dissector with an equal perimeter of the head and rod part, which is composed of a dissection head, a connecting rod and a handle. The dissection head and the connecting rod are integrally connected, and the connecting rod and the handle are connected by threads. The maximum perimeter of the flat dissection head is equal to or approximately equal to the perimeter of the cylindrical connecting rod, so that a skin incision with the same diameter as the connecting rod of the dissector can accommodate the dissection head. Compared with the existing dissector with a large head and a thin rod, it can minimize the skin incision to the greatest extent, and the skin at the incision can better fix the dissector, limit the swing of the connecting rod, and make the subcutaneous tunnel formed by dissection more accurate. The dissection head and the connecting rod are made of bendable metal materials, which can be appropriately bent during the operation according to actual needs to better adapt to the facial contour and reduce unnecessary tissue damage during the dissection process. The handle has an anti-slip design, which is more suitable for grasping by hand, increasing the stability of grasping and improving the comfort of the doctor's operation.

Description

Technical Field

[0001] The present invention belongs to the field of plastic and aesthetic surgical instruments, and particularly relates to a linear minimally invasive wrinkle peeling instrument with an equal perimeter of the head and rod parts. Background Art

[0002] Facial rhytidectomy is one of the plastic and aesthetic surgeries widely carried out clinically. In many cases, subcutaneous peeling is required for the wrinkled parts. However, most of the existing peeling instruments have problems such as "big head and thin rod", large skin incisions required, and inability to fit the facial contour.

[0003] With the minimally invasive development of plastic and aesthetic surgeries and the increasing surgical requirements of patients seeking beauty, the surgical incisions are becoming smaller and smaller. This requires traditional peeling instruments to achieve the minimum skin incision through scientific and reasonable designs. Summary of the Invention

[0004] The purpose of the present invention is to provide a linear minimally invasive wrinkle peeling instrument with an equal perimeter of the head and rod parts, aiming to solve the problems of large skin incisions and inability to fit the facial contour of the existing facial wrinkle peeling instruments.

[0005] To achieve the above purpose, the present invention provides a linear minimally invasive wrinkle peeling instrument with an equal perimeter of the head and rod parts, which is composed of a peeling head 1, a connecting rod 2, and a handle 3. The peeling head 1 and the connecting rod 2 are integrally connected and made of the same material. The connecting rod 2 and the handle 3 are connected by threads. The peeling head 1 is flat, with a blunt and rounded edge having a curvature. Its length is 1 cm to 4 cm, width is 4 mm to 10 mm, and thickness is 1 - 2 mm. The perimeter of the cross-section in the middle of the peeling head 1 is suitable for the perimeter of the connecting rod, and the perimeter = 2×(width + thickness). The connecting rod 2 is cylindrical, with a length of 10 cm to 15 cm.

[0006] Since the surgical incision during the operation should enable the peeling head to enter, accommodate the connecting rod, and achieve the maximum incision utilization rate, the perimeters of the peeling head and the connecting rod are designed to be adaptable.

[0007] The handle is designed in a "gourd shape", with protrusions and depressions, and its surface is rough or provided with anti-slip lines. Its length is 5 cm to 8 cm, and diameter is 5 mm to 8 mm.

[0008] The beneficial effects of the present invention are as follows: (1) The peeling head and the connecting rod with equal perimeters can minimize the size of the skin incision to the greatest extent, and the incision matching the connecting rod provides certain support for the dissector, restricting the swaying of the connecting rod and making the subcutaneous tunnel formed by peeling more regular; (2) The connecting rod and the peeling head made of bendable metal materials can be bent by the doctor according to actual needs. The bendable connecting rod can better adapt to the facial bone contour. For example, it can cross the zygomatic bone area for peeling at a farther location, and the bendable peeling head can better fit the contour of the peeled area. For example, the contour arcs of the forehead and the outer canthus of the eye are different, and it is not suitable to use dissectors with the same arc for operation. (3) The "gourd-shaped" handle is provided with protrusions and depressions, which better meet the physiological needs during hand grasping, and the surface is rough or provided with anti-slip lines, which not only increases the stability of grasping but also improves the operation comfort of the surgeon.

[0011] Figure 3 is a schematic diagram of the perimeter of the cross-section in the middle of the peeling head of the present invention (Perimeter = 2×(Width + Thickness)). DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] The present invention will be further described in conjunction with the drawings and embodiments.

[0013] Embodiment 1

[0014] See Figures 1-3 , the one-word minimally invasive wrinkle peeling dissector with equal perimeters of the head and rod part provided by the present invention is composed of a peeling head 1, a connecting rod 2 and a handle 3. The peeling head 1 and the connecting rod 2 are integrally connected and made of the same material. The connecting rod 2 and the handle 3 are connected by threads. The peeling head 1 is flat, with a blunt and rounded edge and a radian. The length is 1 cm to 4 cm, the width is 4 mm to 10 mm, and the thickness is 1 - 2 mm. The perimeter of the cross-section in the middle of the peeling head 1 = 2×(Width + Thickness). The connecting rod 2 is cylindrical, with a length of 10 cm to 15 cm.

[0015] Both the peeling head and the connecting rod are made of stainless steel (2Cr13 or 3Cr13), which belongs to martensitic stainless steel. This kind of stainless steel can obtain a certain hardness after heat treatment. The present invention requires its hardness to be suitable for being bent appropriately and having a certain strength.

[0016] The maximum lateral perimeter of the flat peeling head 1 is adapted to the perimeter of the cylindrical connecting rod 2 (lateral perimeter ≈ 2×(width + thickness)). During the operation, the surgical incision should be able to allow the peeling head to enter, accommodate the connecting rod, and achieve the maximum incision utilization rate. Therefore, the perimeters of the peeling head and the connecting rod are designed to be adapted to each other.

[0017] The handle 3 is designed in a "gourd shape" with protrusions and depressions, a rough surface or anti-slip patterns, a length of 5 cm to 8 cm, and a diameter of 5 mm to 8 mm. The material of the handle is selected as 304 stainless steel, which has high toughness, plasticity, and good corrosion resistance.

[0018] As Figure 2 shown, both the peeling head 1 and the connecting rod 2 can be bent into different arcs to fit the facial contours of different parts.

[0019] Example 2

[0020] For facial minimally invasive rhytidectomy, an incision is usually made at the temporal hairline area, and the dissector is inserted into the subcutaneous tissue until the area to be dissected. Here, we compare the existing ordinary dissector with a connecting rod diameter of 3 mm and the "one-shaped minimally invasive rhytidectomy dissector with equal perimeters of the head and the rod part" proposed by the present invention. When the diameter is 3 mm, the head of the ordinary facial rhytidectomy dissector is relatively wide, such as 8 mm. According to the principle of equal perimeters of the head and the rod part of the present invention, the head width can be 2.71 - 3.71 mm. Therefore, the incision can be greatly reduced, the damage can be minimized, and the surgical effect can be improved. When the dissector reaches the dissection area and needs to cross the zygomatic bone, the ordinary dissector cannot fit the facial bone contour due to its hard material, which is inconvenient to operate and causes great damage to the tissue. However, the head and the rod part of the dissector of the present invention are both made of bendable martensitic stainless steel, which can be bent according to the actual needs during the operation to fit the facial contour as much as possible and improve the surgical effect.
