Problems solved by technology

However, there is a disconnect between the existing surgical needles and the needs of doctors during the operation. Medical device manufacturers do not participate in clinical practice, and cannot fully understand the requirements and experience of doctors for devices during surgery.
For example, the pinholes of the existing fat extraction needles are arranged in the shape of "品", which is likely to cause problems such as uneven fat extraction, uneven fat extraction areas, and uneven cohesive liposuction; the shape of the pinholes does not conform to the shape of the fat The shape of the cells will cause problems such as large damage to fat cells, excessive oil, and large damage to the fat extraction area; the uneven inner wall of the extraction needle and filling needle will easily lead to damage to fat cells and blockage in the needle tube.

Embodiment 1

[0060] A combination of needles for fat surgery, including an extraction needle I, an extraction needle II and a filling needle.

[0061] Such as figure 1 As shown, the extraction needle I is a hollow structure with a smooth inner wall and no obvious bending, including a needle tip 11 , a needle tube 12 and a connecting seat 13 connected in sequence. The needle point 11 is a closed conical shape, and the end of the needle tube 12 connected to the needle point 11 is provided with three needle holes 121 distributed along a spiral shape, and the distance between adjacent needle holes 121 is 2 mm. The pinhole 121 is elliptical, and the diameters of the pinhole 121 are 2mm×2.5mm, 2mm×3mm and 2mm×3.5mm in descending order along the spiral direction from the needle tip 11 to the connecting seat 13 . The extraction needle I can be connected with the negative pressure device through the threaded interface 131 on the connection seat 13 .

Abstract

The invention relates to a needle assembly for a fat operation. The needle assembly for the fat operation comprises an extracting needle and a filling needle and is characterized in that the extracting needle comprises a needle tip (11), a needle tube (2) and a connecting seat (13) which are connected in sequence, the end, connected with the needle tip (11), of the needle tube (2) is provided with needle holes (121) spirally distributed, the filling needle comprises a needle tip (21), a needle tube (22) and a connecting seat (23) which are connected in sequence, the needle tip (21) is in a gentle circular-arc shape, the end, connected with the needle tip (21), of the needle tube (22) is provided with needle holes (221), and the distance between the needle tip (21) and the adjacent needle holes (121) is 2-3 mm. The needle assembly for the fat operation has the advantages of being small in fat cell damage, small in fat taking operative zone damage, high in extracting efficiency and convenient to use, and the operation safety is improved.

Description

technical field [0001] The invention relates to the field of fat extraction and transplantation, in particular to a needle combination for fat cell extraction and transplantation. Background technique [0002] With the improvement of people's material level, people are more and more concerned about their appearance and pay attention to their image. Many people hope to make themselves more perfect through plastic surgery. After liposuction and autologous fat transplantation became the methods confirmed in the plastic surgery field, they were gradually applied to various fields of cosmetic plastic surgery. Liposuction is a surgical method that uses various types of liposuction tools to suck out excess fat tissue while retaining the dermis and superficial tissue to reshape the shape of the surgical area. At present, the most commonly used tumescent negative pressure liposuction is to use a large negative pressure, use specific surgical tools and tumescent anesthesia techniques...
