Description

Flap fixing device

Technical Field

The utility model relates to the field of medical appliances, in particular to a novel surgical flap fixing device.

Background

In clinical work, breast conservation surgery is currently one of the accepted standard surgical treatment modalities for early breast cancer, but expanding the resection range to ensure negative margins often leads to post-operative bilateral breast asymmetry and even malformation. In recent years, the technology of removing the epidermis of the skin flap with the pedicel is more and more popular, but the skin flap with the pedicel needs to be fixed by a surgeon with one hand, and skin tissues are removed by scissors or blades; on the other hand, the removal of the epidermis by scissors or blades takes a long time, resulting in a low operating efficiency, which is caused by the lack of flap fixtures. At present, no report on skin flap fixing devices related to breast protection operation is found at home and abroad.

Disclosure of Invention

In order to overcome the technical defects, the utility model discloses a novel surgical flap fixing device. The device is realized by the following technical scheme:

the flap fixing device comprises a flap fixing plate A and a flap fixing plate B, wherein the upper ends of the flap fixing plates A and B are flat plates uniformly distributed with small holes; the lower ends of the two handles are respectively provided with a clamp handle, and the two clamp handles are mutually hinged; the two clamp handles can be opened and closed by a specific angle, and the small holes on the two flat plates can be overlapped or staggered.

In order to conveniently fix the state that the small holes on the two flat plates are overlapped or staggered, the near tail ends of the two clamp handles are provided with corresponding ratchet locking structures, and the ratchet locking structures comprise two ratchet locking positions; and after one ratchet locking position is locked, the small holes on the two flat plates are overlapped, and after the other ratchet locking position is locked, the small holes are staggered.

The skin flap fixing device can also be matched with a medical steel needle or a nail similar to the medical steel needle, and other fixing parts which are matched with the small hole in size. The medical steel needle is a needle tip protective sleeve with a larger end and a thin end, and the thin end is provided with a silica gel material

In order to avoid sliding or shifting of the medical steel needle, small teeth are arranged on the inner side of the small hole.

For convenient operation, the upper and lower end side of the flat board of flap fixed plate A upper end is equipped with the draw-in groove, and the upper and lower end side of the flat board of flap fixed plate B upper end is equipped with the flank with above-mentioned draw-in groove looks block. When the flap fixing plate is used, the flat plate at the upper end of the flap fixing plate B is clamped in the clamping groove of the flat plate at the upper end of the flap fixing plate B through the side wings, and the two flat plates are overlapped.

As the preferable scheme of the skin graft technology for removing the skin with pedicel in the breast-protecting operation, the flat plates at the upper ends of the skin flap fixing plate A and the skin flap fixing plate B are made of medical steel, wherein the flat plate at the upper end of the skin flap fixing plate A is a cube with the side length of 20cm and the thickness of 2 mm; the flat plate at the upper end of the flap fixing plate B is a cuboid with the length of 20cm, the width of 19.6cm and the thickness of 2 mm; the flat plate is uniformly distributed with small holes with the diameter of 0.5mm, and the inner sides of the small holes are provided with teeth.

Compared with the prior art, the skin flap fixing device has the beneficial effects that the flat plate uniformly full of small holes can be arranged below the skin flap to be fixed, the skin flap is flatly and flatly attached to the flat plate, the skin flap is fixed on the flat plate by using the medical steel needle, and the exposed needle point is protected by the needle point protective sleeve. Therefore, the skin flap can be smoothly and firmly fixed on the flat plate, and manual grabbing and pinching are replaced. The problems that the skin flap slides, the uneven removal is carried out, fingers are easy to be accidentally injured, or the blood supply of the skin flap is influenced by using a clamp can be avoided; on the other hand, the skin flap can be flatly fixed on the flat plate, so that a professional skin extractor can be used for removing the epidermis, and the operation efficiency is greatly improved.

Detailed Description

The utility model will be further illustrated with reference to specific examples.

As shown in fig. 1 and 2, the flap fixing device of this embodiment mainly comprises a flap fixing plate a and a flap fixing plate B, wherein the upper ends of the flap fixing plates a and B are flat plates A1 and B1 uniformly distributed with small holes 3, the lower ends of the flap fixing plates a and B are respectively provided with a clamp handle A2 and B2, and the clamp handles are hinged with each other and can be opened and closed.

Corresponding ratchet locking structures 4 are arranged on the finger rings at the near tail ends of the two clamp handles A2 and B2 and comprise two ratchet locking positions for controlling the overlapping or staggered states of the small holes on the two flat plates. The first ratchet lock is positioned, the small holes on the two plates are overlapped, the second ratchet lock is positioned, and the small holes on the two plates are staggered.

The flat plate A1 of the embodiment is a cube with the side length of 20cm and the thickness of 2 mm; a cuboid with the length of 20cm, the width of 19.6cm and the thickness of 2 mm; the diameter of the small holes on the two plates is 0.5mm.

As shown in fig. 3, the flat plate A1 and the flat plate B1 of the flap fixing plate a and the flap fixing plate B are engaged with each other by the engagement structure 5. The upper and lower end side surfaces of the flat plate A1 are provided with clamping grooves 51, and the depth of the clamping grooves 51 is about 1mm. The side surfaces of the upper end and the lower end of the flat plate B1 on the flap fixing plate B are provided with side wings 52 which are engaged with the clamping grooves.
