Technical field

Generally speaking, the present invention relates to biomedical sciemtifec and technical sphere more particularly to a kind of tissue excisions and tissue transplantations The instrument and method of object application.

Background technique

The transplanting of parts of body adipose tissue is a kind of relatively common lift face, treatment and structure program, be related to from One position cuts adipose tissue, and is implanted into cut tissue again (usually by working process at another position Tissue) (referring to Coleman 1995 and Coleman 2001).Be mainly used for repairing small lift face defect [such as facial fold, Wrinkle, pockmark and turf trace (divot)] while, the transplanting of adipose tissue in recent years is also used for lift face and/or treatment breast increases Big and reconstruction (Bircoll and Novack 1987；Dixon 1988) and buttocks increase (Cardenas-Camarena, Lacouture et al., 1999；de Pedroza 2000；And Peren, Gomez et al., 2000).

Past, adipose tissue transplantation object and adipose tissue transplantation method encounter many difficulties, there is many side effects, including device Official or histiocytic necrosis, implantation material be absorbed by the body, infect (Castello, Barros et al., 1999；Valdatta, Thione et al., 2001), calcification and cicatrization (Huch, Kunzi et al., 1998), graft are implanted into inconsistent (Eremia With Newman 2000), shortage durability and the other problems as caused by shortage new vessels and transplanting tissue necrosis.This its In, ultimate challenge that adipose tissue transplantation faces first is that implantation material is absorbed by the body with adipose tissue implantation material after the transfer Volume ownership.When cutting or cleaning adipose tissue, the space of the monolithic adipose tissue cut it is hydraulically full (such as water, Blood, Tumescent fluid, oil).When this tissue/fluid mixed liquor is implanted receptor, liquid portion is absorbed by the body quickly, thus Lead to capacitance loss.It is commonly referred to as wherein " adipose tissue exsiccation " or " rouge from the process that tissue/fluid mixed liquor excludes Fluid Volume Fat tissue dewatering ".Induction or exacerbation of disease due to inflammatory reaction, red blood cell and white blood corpuscle in adipose tissue transplantation object Deng content also significantly affect graft implantation after graft ownership.Organize the other side and adipose tissue of ownership Graft inner lipid content is related.It should be understood that there is free lipid in adipose tissue transplantation object (i.e. from killed or wounded Fat cell in the lipid that releases) induction or the exacerbation of disease that can lead to inflammatory reaction, with a large amount of phagocyte Activity eventually causes the loss of transplanting object amount.

It may also be noted that being mixed with the fat not through processing of the fat-derived mesenchyma regenerative cell group of concentration people Tissue overcomes above-mentioned many problems related with adipose tissue transplantation object and adipose tissue transplantation.Especially, addition is without adding The rouge containing the fat-derived mesenchyma regenerative cell group of concentration people being made of the fat-derived mescenchymal stem cell of people of work processing Fat tissue increases weight, angiogenesis and the ownership of fat graft.(see United States Patent (USP) No.7390484 and it is common not Certainly U.S. Patent Application Publication No.2005/0025755 clearly has it all referring to data in both of these documents).With animal mould There is no the adipose tissue transplantation object added at all to compare in type, adds or be mixed with and be made of the fat-derived mescenchymal stem cell of people The adipose tissue fragment of the fat-derived mesenchyma regenerative cell group of people is concentrated, graft has preferable angiogenesis ability and filling Note ability.Moreover, compared with un-added graft, added with the people's fat source being made of the fat-derived mescenchymal stem cell of people The graft ownership and weight of property mesenchyma regenerative cell's adipose tissue can all gradually increase.(see U.S. Patent Application Publication Specification No.2005/0025755).In addition, the probability of infection can be greatly reduced in closed bactericidal fluid path diameter processing adipose tissue. The progress that above-mentioned animal model obtains in terms of adipose tissue autologous transplanting has also been studied according to for Human clinical.Although such as This, the isolation and purifying of the fat-derived regenerative cell group of the concentration people being made of people's fat-derived stem cells (ADSC) usually requires A series of cleaning, digestion, filtering and/or centrifugation step, these steps can reduce the yield of competent cell, machinery needed to set Quality, appearance, service life, hydratability or the efficiency of standby, professional clinician and/or influence graft.

Adverse reaction is occurred to the adipose tissue cut moreover, stress may cause.For example, such stress include exposure To the storage time etc. cut in above-mentioned environmental pathogens, after extending.

Although being developed some instruments and system (such as instrument described in United States Patent (USP) No.9133431B2) to solve Certainly the above problem and meet needs, but need other methods also to prepare and optimize graft and the implantation material of adipose tissue, And it is isolated and is concentrated the fat-derived regenerative cell of remaining people.Following Examples is just able to satisfy above-mentioned needs.
