The cleft palate operation gagOne, technical field
This utility model relates to a kind of cleft palate operation gag.
Two, background technology
In the operation of cleft palate treatment, because the amplitude that the patient dehisces is bigger, the time is longer relatively, for guaranteeing operation technique, needs the open-shaped attitude in oral cavity that special apparatus assists to support the patient.Existing cleft palate operation gag mainly contains two parts and forms, mouthful outer volume bigger, the outstanding pressure tongue mechanism of similar tetragonal bracing frame and bottom.This gag is inconvenient operation not only, and because mouthful outer partial volume is big, fixes insecure in the art, influence doctor's operation technique, particularly because its spatula fixed angle at different patients' operation, also needs to select to change large, medium and small three kinds of spatulas.
Three, summary of the invention
This utility model is at deficiency of the prior art, provide a kind of easy to operate, mouthful outer mechanism volume is little, the cleft palate operation gag that is applicable to various patients.
This utility model adopts following technical proposals:
The cleft palate operation gag, form by bracing frame and pressure tongue mechanism, it is characterized in that, bracing frame is made of pincerlike two bow-shaped supports, open round about in vertical direction after two support one end axles connect, the end is bent to form the pincers handle in the horizontal direction backward, and other end end axis connects, mid-stent is provided with aduncate drag hook up and down, presses tongue mechanism to be arranged on the lower carriage middle part.
Described bracing frame has been provided with the flexible fastening sheet of qualification effect, and the pincers that this flexible fastening sheet one end is fixed on lower carriage are provided with a square groove last in the middle of the other end end, and this groove is stuck on the fixing card; Fixing card is chopper shape thin slice, and an inside side tool blade is provided with plurality of teeth, and the one end flexibly connects by connecting axle and lower carriage, and the other end passes the groove on the upper bracket.
Described pressure tongue mechanism is made up of spatula, bolt, fixing head and arc frame, and spatula one end is provided with vertical with it two baffle plates, and outer side shield is a hollow frame, and two baffle plate central bottom are looped around on the drag hook; It is interior, relative with the lower carriage drag hook and be fixedly connected on the outside, lower carriage middle part that arc frame is located at the horizontal plane of lower carriage; The arc top that fixing head is arranged on arc frame is gone up and perpendicular to the arc frame plane, is provided with screw in the middle of the fixing head top; Bolt passes the outer side shield on fixing head screw and the spatula, contacts with the interior side shield of spatula.
Described spatula is made up of two boards, is Collapsible structure.
Described drag hook both sides inclination up and down respectively of going up on the lower carriage.
Advantage of the present utility model: reasonable in design, simple in structure, mouthful outer volume is little; The angle of spatula can be regulated by bolt is convenient, and its flexible design can make gag be applicable to all kinds of patients; By the pincers handle, gag is regulated and is fixing very convenient, is convenient to operation, mouth opening fixation in the art, and postoperative takes out gag easily.

The utility model will be further described below in conjunction with accompanying drawing.
Embodiment:
The cleft palate operation gag, form by bracing frame 1 andpressure tongue mechanism 2, it is characterized in that, bracing frame 1 is made of pincerlike two bow-shaped supports, upper bracket 3 with open round about in vertical direction afterlower carriage 4 one end axles are connected, the end is bent to form pincers in the horizontal direction backward 5, the connection of other end end axis, lastlower carriage 3,4 middle parts are respectively equipped with aduncate drag hook,press tongue mechanism 2 to be arranged onlower carriage 4 middle parts.
Described bracing frame 1 has been provided with theflexible fastening sheet 7 of qualification effect, and the pincers that theseflexible fastening sheet 7 one ends are fixed onlower carriage 4 are provided with a square groove on 5 in the middle of the other end end, and this groove is stuck on thefixing card 8;Fixing card 8 is a chopper shape thin slice, and an inside side tool blade is provided with plurality of teeth, and the one end flexibly connects by connecting axle andlower carriage 4, and the other end passes thegroove 9 on the upper bracket.
Describedpressure tongue mechanism 2 is made up ofspatula 10, bolt 11, fixinghead 12 andarc frame 13, andspatula 10 1 ends are provided with vertical with it two baffle plates, andouter side shield 14 is hollow frames, and two baffle plate central bottom are looped around on thedrag hook 6;Arc frame 13 is located in the horizontal plane oflower carriage 4, relative with lowercarriage drag hook 6 and be fixedly connected on outsidelower carriage 4 middle parts; The arc top that fixinghead 12 is arranged onarc frame 13 is gone up and perpendicular to the arc frame plane, is provided withscrew 16 in the middle of fixinghead 12 tops; Bolt 11 passes theouter side shield 14 on fixinghead screw 16 and the spatula, contacts with theinterior side shield 15 ofspatula 10.
Describedspatula 10 is made up of two boards, is Collapsible structure.
Describeddrag hook 6 both sides inclination up and down respectively of going up on the lower carriage.
Spatula 10 is made up of two boards, groove is arranged on one of the position infra, and another piece is provided with rivet, can move along groove, constitutes Collapsible structure like this, can change the length of spatula 10.The baffle rings ofspatula 10 is ondrag hook 6, sospatula 10 can rotate around drag hook.Because bolt 11 contacts with theinterior side shield 15 ofspatula 10, canspatula 10 be rotated arounddrag hook 6 by the precession or the back-out of bolt 11 like this, adjust the angle ofspatula 10.
When this utility model uses, in the drag hook posting port of last lower carriage, strut the oral cavity,, the tooth offixing card 8 is stuck on thegroove 9 of upper bracket 3, utilize lever principle, thereby play the effect of fixing support rack 1 to suitable opening angle by means of the strength that clamps 5.Regulate the length and the angle ofspatula 10 then, can undergo surgery.
