Description
Technical field
This utility model relates to a kind of abdominal otch dilator, while being exclusively used in out abdomen operation, otch is strutted, and belongs to technical field of medical instruments.
Background technology
Open in abdomen operation process at human body, need otch to strut, be conducive to get a clear view in body, particularly small incision surgery, needs special otch distraction instrument.Prior art is opened abdomen operative incision to human body and is strutted, to carry out the backward otch of gripping otch by general pincers class to open outward, its defect is that operation application does not match, particularly little otch, otch opens just more inconvenient, easily causes otch damage, the effect of impact operation, extend operating time, can not meet desirable surgical effect.
Utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in prior art, and provides a kind of reasonable in design, the abdominal otch dilator that can effectively operative incision be strutted.
This utility model solves the problems of the technologies described above adopted technical scheme: a kind of abdominal otch dilator, it is characterized in that: it comprises trumpeter's handle and two trumpeter's handles, the middle part of one trumpeter's handle and two trumpeter's handles is flexibly connected by bolt, the front end of one trumpeter's handle and two trumpeter's handles is respectively arranged with one and struts head, strut in head and be provided with and strut groove, two strut head symmetrical coupling mutually, strut after a closure, and two strut groove closed docking mutually; A described handle end is provided with tooth plate, and one end of tooth plate is fixed on trumpeter's handle, the end clamping of the other end and two trumpeter's handles; The end of described trumpeter's handle and two trumpeter's handles is provided with resetting means.
Resetting means described in the utility model comprises spring, and spring has two, and one end of two springs is separately fixed at the end inner side of trumpeter's handle and two trumpeter's handles, and the other end of two springs is connected to each other.Spring is for the reset of trumpeter's handle and two trumpeter's handles.
One side of tooth plate described in the utility model and two trumpeter's handle clampings is provided with tooth bar, and the end of two trumpeter's handles is provided with latch, and latch snaps in tooth bar and fixes.When operation, can, by trumpeter's handle and two trumpeter's handles location, can not move, operation is carried out smoothly.
The groove that struts described in the utility model is semicircle column type, and two strut groove and form cylindrical groove when closed.Strut effectively, operating theater instruments opereating specification is large.
This utility model compared with prior art, has following positive effect: reasonable in design, and can effectively otch be strutted and be located, operating theater instruments is performed the operation by the otch strutting, improve operation efficiency.
