Description
Technical field
This utility model relates to a kind of medical instruments, and a kind of urethra dilator specifically is provided.
Background technology
Clinically, there is part Urology Surgery operation need utilize apparatus such as tweezers to expose the operative site at shallow urethra place, not only operation inconvenience, also existing influence surgical field of view, is difficult for deficiencies such as fixing, has influenced carrying out smoothly of performing the operation to a certain extent.
Summary of the invention
This utility model is at above-mentioned the deficiencies in the prior art, and a kind of urethra dilator easy to use is provided.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of urethra dilator, comprise moving caliper, fixed caliper, moving caliper and fixed caliper are hinged, the working end of moving caliper and fixed caliper is symmetrically fixed with arc and struts sheet, the moving caliper handheld terminal is hinged with support bar, the fixed caliper handheld terminal has at least one spacing draw-in groove, and spacing draw-in groove is corresponding with the head end of support bar.
The cross section that described arc struts sheet is a half elliptic.
Described arc struts sheet and is positioned at the planar side of moving caliper and fixed caliper place.
Urethra dilator of the present utility model provides specific purpose tool for exposing shallow operation on urethra position, compared with prior art has following beneficial effect highlightedly:
(1) handheld terminal has certain distance apart from the working end, and is easy to use when hands is held handheld terminal and operated, and hand can not block sight line;
(2) utilize support bar and spacing draw-in groove location, be difficult for becoming flexible, be convenient to operation and carry out smoothly.
Description of drawings
Accompanying drawing 1 is the structural representation of this utility model urethra dilator;
Accompanying drawing 2 is that the A of urethra dilator shown in Figure 1 is to view.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
Shown in accompanying drawing 1,2, urethra dilator of the present utility model is mainly by moving caliper 1, fixed caliper 2 and strut sheet 3 and constitute.Moving caliper 1 is hinged with fixed caliper 2.Two half elliptics strut the working end that sheet 3 symmetries are fixed on moving caliper 1 and fixed caliper 2, and two strut sheet 3 and all are positioned at moving caliper 1 and the planar side in fixed caliper 2 places.Moving caliper 1 handheld terminal is hinged with support bar 4, and fixed caliper 2 handheld terminals have three spacing draw-in grooves 5, and spacing draw-in groove 5 is corresponding with the head end of support bar 4.
During use, the involutory sheet that struts is inserted urethral orifice, utilize moving caliper, fixed caliper to make two to strut sheet and open relatively then, urethra is strutted utilize to the suitable size the support bar of handheld terminal and the spacing draw-in groove positioning instant can.
