Abstract
The utility model discloses a medical skin soft tissue expander, which comprises a short cylindrical injection pot, a connecting conduit and an expansion bulb. The injection bottle is divided into an upper cavity and a lower cavity by a partition portion disposed inside the injection pot, and the upper cavity and the lower cavity are communicated with the expansion bulb through the same connecting conduit. The injection pot is ingenious in design and features in two-side water injection. During use, water injection cannot be affected even the injection pot is overturned, and thereby success rate of surgeries is increased effectively.
Description
Technical field
This utility model relates to a kind of medical skin soft tissue expander, is specifically related to a kind of skin tissue expander to the improvement of injection kettle profile, belongs to the medical instruments field that the plastic surgery uses always.
Background technology
In field of orthopedic surgery, in order to repair the big skin injury after the excision of body surface cicatrix or swollen thing, the doctor uses a kind of skin tissue expander usually.This dilator mainly comprises expansion capsule, injection kettle and connecting duct three parts.During use, it is subcutaneous in advance dilator to be embedded in damaged edge, and the injection kettle is by connecting duct water filling in the expansion capsule regularly, treat that skin is finished expansion after, take out dilator, excision simultaneously is sick to be decreased, and utilizes the skin of expansion to finish damaged reparation.
Yet the weak point of above-mentioned dilator is: the injection kettle is designed to that upper surface is less, lower surface is bigger and the truncated cone-shaped structure of whole short weak point, and injection kettle bottom inner surface is provided with stainless steel substrates, and this injection kettle can only pass through a side water filling.Though the shape setting of above-mentioned injection kettle can prevent to inject the kettle upset to a certain extent, in clinical use, still have certain injection kettle upset incidence rate, and the injection kettle is in case overturn, cause surface stainless steel up, just can't carry out water filling, cause operative failure.
The utility model content
In order to solve the problems of the technologies described above, this utility model provides a kind of medical skin soft tissue expander.
Its technical solution is:
A kind of medical skin soft tissue expander, comprise injection kettle, connecting duct and expansion capsule, the injection kettle is connected with the expansion capsule by connecting duct, being shaped as of described injection kettle is cylindrical, be provided with cutting part in injection kettle inside, described cutting part will be injected kettle and be divided into upper cavity and lower chamber, and upper cavity all is connected with the expansion capsule by same connecting duct with lower chamber.
Above-mentioned cutting part is a rustless steel thin slice.
Above-mentioned rustless steel thin slice is arranged on the center position of injection kettle inside, and the plane at this rustless steel thin slice place is parallel with injection kettle upper surface/lower surface.
The height of above-mentioned injection kettle is less than the bottom surface diameter of injection kettle.
Useful technique effect of the present utility model is:
Injection kettle design in this utility model is ingenious, but has the characteristics of two sides water filling, in use, even the upset of injection kettle can not influence water filling yet, can effectively improve success rate of operation.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the longitudinal sectional drawing of Fig. 1, and injection kettle part mainly is shown.
The specific embodiment
In conjunction with the accompanying drawings, a kind of medical skin soft tissue expander comprises injection kettle 1, connecting duct 2 and expansion capsule 3, injection kettle 1 by connecting duct 2 with expand capsule 3 and be connected.Inject the short cylindrical shape that is shaped as of kettle 1, wherein, the height of injection kettle 1 is 1:2 with the bottom surface diameter ratio of injection kettle 1; Inside center position at injection kettle 1 is provided with rustless steel thin slice 4, and the plane at these rustless steel thin slice 4 places is parallel with the upper surface or the lower surface of injection kettle 1.Rustless steel thin slice 4 will be injected kettle 1 and be divided into the upper cavity 5 and lower chamber 6 that volume equates, upper cavity 5 all can be used as the water filling lacuna with lower chamber 6.Simultaneously, injection kettle 1 is connected with connecting duct 2 at its place, lateral centre position, and the rustless steel thin slice 4 that the place, centre position is provided with separates the inner chamber porch of connecting duct 2, and promptly the water in upper cavity 5 and the lower chamber 6 all can be delivered in the expansion capsule 3 by connecting duct 2.
Need to prove, any equivalent way that those skilled in the art have done under the instruction of this description, or obviously variant all should be in protection domain of the present utility model.
