Flap water injection needle for breast endoscopic surgery

Abstract

The invention relates to the technical field of medical instruments, in particular to a flap water injection needle for a breast endoscopic surgery. Comprising a needle body structure and a fixing structure, the needle body structure comprises a straight needle rod, an arc-shaped needle rod is arranged at the top end of the straight needle rod, one end, away from the straight needle rod, of the arc-shaped needle rod is a needle rod tip, a water outlet is formed in the needle rod tip, a water supply hole is formed in the needle body structure, and a limiting groove is formed in the side of the straight needle rod. A fixing structure is arranged on the straight needle rod body in a sleeving manner, and the fixing structure comprises a sleeve. The water injection needle has the advantages that water injection of breast flaps is carried out by changing the tip end of the water injection needle and designing the needle rod in the needle body structure into the arc-shaped needle rod close to the radian of the female breast. 1 / 5 of the foremost end of the tip end of the needle rod is sharp so as to puncture a breast flap conveniently, and the rear part of the tip end is blunt so as to prevent the puncture from entering a gland layer due to too deep puncture, so that the accuracy of a puncture layer is ensured; the arc-shaped needle rod can reach the opposite side of the breast by means of the radian similar to that of the breast, so that skin puncture caused by picking up the breast is avoided, puncture safety is guaranteed, finally, puncture water injection of the whole breast flap is even and located on the surface of subcutaneous fat and glands of the breast, and good level preparation is provided for a later cold knife operation.

Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a flap water injection needle used in breast laparoscopic surgery. Background Art

[0002] Currently, in breast laparoscopic surgery, good separation of breast flaps is the key to successful surgery, and the cold knife method is the most reliable surgical method. The most critical step in the cold knife method is the injection of water into the flap. Diluted adrenaline water or lipolysis solution (selected according to surgical needs) is injected evenly and comprehensively into all parts of the breast flap through the injection needle to find the right level for the cold knife treatment and ultimately achieve the separation of the breast flap.

[0003] At present, there is no good water injection needle for breast flap. The water injection needles used are generally longer anesthesia needles, pneumoperitoneum needles for laparoscopic surgery, or lipolysis needles for plastic surgery. Existing water injection needles cannot be safely and effectively used in breast laparoscopic surgery. The reason is that the anesthesia needle or pneumoperitoneum needle is in the shape of a straight needle shaft, and the breast has a clear bulge and curvature, so this type of water injection needle can only reach the place near the injection point, and cannot cross the curvature of the breast to inject the opposite side of the breast. In addition, if the straight water injection needle is forcibly pushed in, it may also lift the skin on the surface of the breast and cause damage to the skin on the surface of the breast. The tip of the existing lipolysis needle in the plastic surgery department is too blunt, and puncture is more difficult, which can easily lead to uneven thickness of the flap, and eventually lead to flap necrosis. Therefore, it is particularly important to design a flap injection needle specifically for breast laparoscopic surgery. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the above-mentioned technology. The technical solution adopted by the present invention is:

[0005] A skin flap water injection needle for breast laparoscopic surgery, characterized in that it includes a needle body structure and a fixing structure, the needle body structure includes a straight needle rod, an arc-shaped needle rod and a needle rod tip, the straight needle rod is provided with an arc-shaped needle rod at the top end, the arc-shaped needle rod is away from the straight needle rod and has a needle rod tip in a rhombus shape, and water outlets are provided on its upper and lower surfaces, wherein the front end 1 / 5 of the tip is sharp, and the rest is blunt, a water supply hole is provided inside the needle body structure, a limiting groove is provided on the side of the straight needle rod, a fixing structure is sleeved on the rod body of the straight needle rod, the fixing structure includes a sleeve, the sleeve is sleeved on the straight needle rod, the sleeve is adapted to the straight needle rod, a limiting strip is provided inside the sleeve, a plurality of the limiting strips are movably inserted in a plurality of the limiting grooves, the limiting strips are adapted to the limiting grooves, an operating piece is provided on the side of the sleeve, a syringe is inserted at the bottom end of the straight needle rod, and the top of the syringe is inserted in the water supply hole and adapted to the water supply hole.

[0006] Preferably, the water outlet holes are relatively arranged on the upper and lower surfaces of the needle rod tip.

[0007] Preferably, the water supply hole is arranged inside the arc-shaped needle rod and the straight needle rod, the water supply hole is connected with the water outlet hole, and one end of the water supply hole passes through the straight needle rod body and is arranged away from one end of the arc-shaped needle rod.

[0008] Preferably, the plurality of limiting grooves are equidistantly distributed on the sides of the straight needle rod.

[0009] The beneficial effects of the present invention are:

[0010] The breast flap is injected with water by changing the tip of the injection needle and designing the needle bar in the needle body structure into an arc-shaped needle bar that is close to the curvature of the female breast. The front 1 / 5 of the needle bar tip is sharp, which is convenient for puncturing the breast flap, while the bluntness of the back of the tip prevents the puncture from being too deep and entering the glandular layer, ensuring the accuracy of the puncture level; and the arc-shaped needle bar, with the help of the curvature similar to the breast, can reach the opposite side of the breast to avoid skin puncture caused by lifting the breast, ensuring the safety of the puncture, and finally achieving uniform puncture and water injection of the entire breast flap and located on the surface of the subcutaneous fat and glands of the breast, providing a good layer preparation for the later cold knife surgery.
