Description
Technical field
The present invention relates to a kind of histoorgan implantation technique, more specifically, it relates to a kind of easy to operate tissue kind
Plant device.
Background technology
In recent years, the female patient quantity suffering from tumor improves constantly, and age of onset has the trend of rejuvenation.Constantly enter
The treatment means of step also makes increasing young tumor women require to preserve reproductive function.At present, cryopreserved human ovary tissue
Or ovary tissue In vitro culture is the most of the same race or xenotransplantation has become as the study hotspot preserving cancer female fertility function, for cancer
Disease patient recovers himself ovarian function and preservation brings new hope fertility.How to promote experimental technique to be easy to quickly
Location maximum minimizing graft damage are one of study hotspots.At present, research both at home and abroad there is no the transplanting of optimum ovary tissue
Optimal site final conclusion, but can confirm that be optimum transplantation site must possess can for tissue implantation and survive growth provide
Good condition and facilitate the detection of follicle and the position of oocyte pickup, and have popular research to be all planted at receptor muscle.Mesh
Front implantation methods mostly is surgical incision skin, by becoming chorista, expansion interstice, tweezers clamping tissue to insert, sew up.This
All planting patterns wounds of planting are relatively big, indolence, and experimental period is long, easy infection, needs many days injection of antibiotics, is unfavorable for seeing
Examining inflammatory reaction and immunoreation after transplanting, easy damaged ovary tissue, operation complexity, experimental period is long.Therefore it is the most fixed to find
Position the maximum experiment equipment reducing graft damage, can facilitate experimenter to operate, and is greatly reducing graft damage base
Graft damage is alleviated, to graft later stage life quality also important in inhibiting on plinth.
Chinese patent notification number CN102427776B, discloses a kind of transplantation device, keeps thin slice including a pair flexibility,
For graft being maintained between holding thin slice；Wherein, each keeps thin slice to include a handle part, is used for holding this
Keep thin slice；And by the direction leaving graft be pulled into handle part at least one, and expose be maintained at
Keep the graft between thin slice.By using this transplantation device can be easily by graft transplantation to lamellar tissue, and not
The tissue around graft or implant site can be destroyed.The operation inconvenience of this transplantation device, wound is relatively big, indolence, experiment
Cycle is long, easy infection, needs many days injection of antibiotics, is unfavorable for observing inflammatory reaction and immunoreation after transplanting, easy damaged group
Knitting, experimental period is long.
Summary of the invention
Instant invention overcomes the device operation inconvenience of existing tissue transplantation, wound is relatively big, indolence, and experimental period is long,
Easy infection, needs many days injection of antibiotics, is unfavorable for observing inflammatory reaction and immunoreation after transplanting, easy damaged tissue, experiment
The deficiency of time length, it is provided that a kind of tissue planter, it is easy to operate, and wound is less, and healing is fast, and experimental period is short, is difficult to
Infect, it is not necessary to many days injection of antibiotics, it is simple to observe inflammatory reaction and immunoreation, not easy damaged tissue after transplanting, during experiment
Between short.
In order to solve above-mentioned technical problem, the present invention by the following technical solutions: a kind of tissue planter, including hollow
Plantation cutter and inner core, inner core is movably arranged in plantation cutter, and plantation cutter includes cutter head and handle of a knife, the tapered structure of cutter head, cutter head
