Description

Technical Field

[0001] This utility model relates to the field of surgical retractor technology, and in particular to a multifunctional surgical retractor. Background Technology

[0002] Retractors are commonly used medical instruments in surgery. They are mainly used to expand the surgical field, fix tissues, and protect surrounding organs. In various surgeries, retractors can help doctors break through the obstruction of the body surface and superficial tissues by opening up the tissues, and clearly expose the deep anatomical structures.

[0003] However, surgical retractors currently have certain limitations in practical applications. The elasticity, toughness, and lubrication of tissues vary in different parts of the body. Especially in areas rich in fat or with loose muscles, retractors struggle to stably retract tissues, easily leading to tissue slippage and dislocation. This can cause the surgical incision to be obscured by deep internal tissues, interfering with the surgeon's observation of the surgical area and consequently affecting the precision and final outcome of the surgery.

[0026] Reference Figures 1-3 As an embodiment of the present invention, a multifunctional surgical retractor is provided, which includes a hollow support column 1 and two movable frames 2 slidably sleeved on the hollow support column 1. The hollow support column 1 is used to support and fix the entire device. The distance between the two movable frames 2 is adjustable to accommodate different incision sizes in surgical procedures. At least one retractor 3 with a notch at the bottom is slidably arranged on the movable frame 2. The number of retractor 3 can be increased according to the incision length to ensure that the retractor 3 can maintain the stability of the incision size.

[0027] like Figure 5As shown, the movable frame 2 consists of a slider 21, a first screw 22, and a splined shaft 23 with multiple fastening holes 24 equidistantly spaced on its surface. The slider 21 is slidably sleeved on the hollow support column 1. The first screw 22 is threaded through the end of the hollow support column 1, and one end of the first screw 22 is rotatably connected to the slider 21. The splined shaft 23 is fixed to the outside of the slider 21. The slider 21 consists of an inner ring, an outer ring, and two connecting parts. The inner ring is slidably disposed inside the hollow support column 1, and the outer ring is slidably disposed outside the hollow support column 1. The inner ring and the outer ring are connected by two connecting parts, and the connecting parts penetrate the hollow support column 1. The slider 21, composed of the inner ring, the outer ring, and the connecting parts, can slide horizontally on the surface of the hollow support column 1 to prevent it from shifting during the sliding process.

[0028] It also includes a support plate 4 hinged in the bottom notch of the retraction frame 3. The size of the support plate 4 is adapted to the size of the notch on the retraction frame 3. In the first half of the retraction operation, the support plate 4 is parallel to the retraction frame 3. The outer side of the support plate 4 is provided with an anti-slip surface. The anti-slip surface can increase the contact friction between the support plate 4 and the internal tissue, making their relative position more stable and preventing tissue from sliding and affecting the shape of the sectional opening.

[0029] The retraction frame 3 consists of a retraction blade 31 with a side plate, a sliding sleeve 32, and a second screw 33. The sliding sleeve 32 is slidably mounted on the splined shaft 23. The second screw 33 is threaded through the sliding sleeve 32, and one end of it is inserted into the corresponding fastening hole 24. By cooperating with the second screw 33 and multiple fastening holes 24, the position of the sliding sleeve 32 can be adjusted, thereby adjusting the position of the retraction blade 31 to meet the requirements of the incision. The retraction blade 31 is connected to one side of the sliding sleeve 32. The retraction blade 31 is arc-shaped, and its convex surface contacts the incision. The adjusting frame 5 and the connecting rod 6 are both located in the concave area of ​​the retraction blade 31. By concealing the adjusting frame 5 and the connecting rod 6, it is possible to prevent them from interfering with the surgical work area.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, a vertically movable adjustment frame 5 is horizontally installed on the retraction frame 3. A connecting rod 6 is hinged between the adjustment frame 5 and the support plate 4. When the adjustment frame 5 moves down, the support plate 4 tilts inward into the incision. The anti-slip surface supports the lower edge of the incision lining. After tilting, the support plate 4 supports the lower edge of the internal tissue inward, preventing some tissues with thicker fat from sliding during the operation and avoiding the lower edge of the tissue from moving past the retraction blade 31 to the incision position, thus interfering with the surgical field of vision.

[0031] The adjusting frame 5 consists of an L-shaped lifting plate 51 and a third screw 52. The L-shaped lifting plate 51 is slidably mounted on the pulling frame 3. The connecting rod 6 is hinged to the bottom of the L-shaped lifting plate 51. The third screw 52 is threaded through the pulling frame 3 and its bottom end is rotatably connected to the L-shaped lifting plate 51. By turning the third screw 52, ​​the height of the L-shaped lifting plate 51 can be adjusted, which facilitates the pushing of the connecting rod 6 to drive the support plate 4 to rotate around the hinge point between it and the pulling blade 31.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
