Effect-increasing type interlayer negative pressure blocking preventing liposuction device

Abstract

The invention relates to a medical instrument, in particular to an effect-increasing type interlayer negative pressure blocking preventing liposuction device which is composed of a liposuction head, liposuction holes, a fat discharging seat, a fat discharging hole, a sleeve shell, a liposuction tube and a fat discharging cavity. The fat discharging seat, the sleeve shell and the liposuction tube have the same axial lead. The fat discharging cavity is an annular space jointly formed by the outer wall of the sleeve shell, the inner wall of the fat discharging seat and the outer wall of the liposuction tube in the fat discharge seat. A plurality of rod holes are evenly distributed on the part, located inside the fat discharging seat, on the wall of the liposuction tube. The effect-increasing type interlayer negative pressure blocking preventing liposuction device has stronger reverse dredging effect, is higher in liposuction efficiency, and causes less abrasion on the inner surface of skin.

Description

technical field [0001] The invention relates to a medical device, in particular to a synergistic interlayer negative pressure anti-clogging liposuction device. Background technique [0002] In body shaping or plastic surgery, it is often necessary to absorb the subcutaneous fat tissue in the hypertrophic part of the human body. In the prior art, there is no suitable special liposuction device that can absorb the subcutaneous fat tissue in the hypertrophic part of the human body. It is an ordinary medical 18-gauge, 20-gauge or 22-gauge injection needle or steel needle tube (inner diameter 1.5-3.5 mm), and the needle tip is ground into an open bevel or a closed round shape. Such a structure has the disadvantages of being sharp and easily causing muscle damage, easy to block, and low suction efficiency. [0003] The application number is 201010177106.0 "porous safety anti-clogging liposuction device", which uses the combination of spherical liposuction head and hemispherical c...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the casing blocks more than half of the liposuction holes of the liposuction head, the efficiency of liposuction is greatly reduced, but without the casing, the liposuction head cannot be fixed, which is a contradiction that cannot be solved by the existing technology

[0005] 2. The fat attached to the surface of the liposuction head will enter the gap between the liposuction head and the casing with the rotation of the liposuction head. Although the fat has a lubricating effect, it accumulates in the above gap , will still increase the friction coefficient between the liposuction head and the casing, and the embedding of fat has a greater impact on the flexibility of the liposuction head, thereby reducing the suction efficiency

[0006] 3. Although the liposuction head has multiple liposuction holes, due to the limited area of ​​the through hole at the junction of the liposuction rod end and the casing, it becomes the "bottleneck" of the suction channel, so the so-called "simultaneous multi-hole suction" cannot Play a role in improving suction efficiency

Therefore, the number of suction holes that have a suction direction from the outside to the inside and can be dredged by the suction from the inside to the outside is very limited, which cannot give a good response to the liposuction holes. unblocking effect

[0008] 4. Due to the existence of protruding components such as shafts and shaft caps, the wear of the components on the inner surface of the skin will be further aggravated during the operation, which is very unfavorable for postoperative recovery
