Detailed Description
The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by persons skilled in the art without making creative efforts based on the embodiments in the present invention are all within the protection scope of the present invention.
A unidirectional dilator for blood training comprises a dilating sac 1, a water injection connecting pipe 2, a water injection kettle 3, a hard chassis 4, a groove 5, a stem cell injection kettle 7 and a stem cell connecting pipe 6; one end of the water injection connecting pipe 2 is communicated with the expansion bag 1, and the other end is communicated with the water injection kettle 3; a hard chassis 4 is arranged on the bottom surface of the expansion bag 1, and the peripheral surface of the hard chassis 4 is provided with a groove 5 which is concave inwards; one end of the stem cell connecting pipe 6 is connected and communicated with the stem cell injection kettle 7, and the other end is bent to one side and arranged in the groove 5. The grooves are used for expanding the skin flap in the next step after the expander is embedded for blood training.
The hard chassis 4 is a composite body composed of a silica gel pad and a titanium net wrapped outside the silica gel pad.
The expansion bag 1 is a silica gel bag with elastic expansion.
The expanded shape of the expansion bag 1 is hemispherical, and the bottom surface of the expansion bag 1 after expansion is still attached to the hard chassis 4.
The whole water injection kettle 3 is in a frustum shape, the inner cavity of the water injection kettle 3 is connected and communicated with the water injection connecting pipe 2, the whole stem cell injection kettle 7 is in a frustum shape, and the inner cavity of the stem cell injection kettle 7 is connected and communicated with the stem cell connecting pipe 6.
The size of the stem cell injection kettle 7 is smaller than that of the water injection kettle 3
The dilator of the present invention has three parts functionally. The first part is one-way expansion, the existing expander is a soft bag, the expansion force after water injection is diffused to four directions, so that the expansion of the bag in four directions can occur when the bag is implanted into a body, the hard chassis 4 is arranged at the bottom of the expansion bag 1, and the hard chassis 4 can block the downward pressure of the expansion bag 1 by using a silica gel pad and a titanium net. The second part is blood training, a groove 5 is added on the outer circumferential surface of the hard chassis 4, the groove 5 is used for carrying out effective blood training by adopting a blood training device after the expander expands (the blood training device is carried out by utilizing the principle of leather tube blood training), after training, the expanded skin flap is formed into an axial skin flap, and finally, enough skin is obtained so as to make full use of the expanded skin. The third part can be used for introducing stem cells and cytokines to enhance the expansion effect, and the embodiment is also provided with a stem cell injection pot 7 and a stem cell connecting pipe 6, wherein the opening of the stem cell connecting pipe 6 is arranged in the groove 5, so that stem cells or cytokines can be introduced into the bottom of the expansion sac 1 and the gap between the expansion sac 1 and subcutaneous tissues from the injection pipe.
As shown in fig. 3, this embodiment is illustrated with a chest scar as an example. Firstly, a conventional dilator implantation operation is adopted to carry out a imbedding dilator operation, a general anesthesia is selected for the child patient, an incision is made at the outer side of a scar at one side, and a wound with a capsule cavity and a dilator chassis size is peeled off. After implantation of the dilator, the suture was disconnected 8 days after surgery, water injection was started, and water was injected once every other day. To the late stage of injection, autologous stem cells may be injected from another stem cell injection pot 7, or cytokines or CGF (growth factors) may be injected. When the injection amount is 100% of the original injection amount, stopping the injection. After 2 weeks of expansion, blood training with a blood trainer was started. The groove 5 of the hard chassis 4 is tightened and pressurized by adopting an elastic band, a blood inlet (namely, the vascular pedicle position trained by expanding the skin flap) is reserved, then a hand tightening machine is adopted, the expanded skin (except the vascular pedicle position) embedded with the expander is tightened by hand, when the blood training time reaches 8 hours, the island skin flap can be trained, the scar can be surgically removed, the expander is taken out, and the trained pedicle is taken as the pedicle of the skin flap to transfer the skin flap to repair the defect.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the foregoing embodiments, and that the foregoing embodiments and description are merely preferred embodiments of the invention, and are not intended to limit the invention, but that various changes and modifications may be made therein without departing from the novel spirit and scope of the invention, which is defined by the appended claims.
