The technical solution of the utility model is as follows:
Above-mentioned Novel oropharynx operation gag, including opening pressure tongue frame and the adjusting bracket being installed on described opening pressure tongue frame；Described opening pressure tongue frame be structure as a whole, its two ends respectively to same lateral buckling and bending after one end be spatula；Meanwhile, the stage casing outer wall of described opening pressure tongue frame is provided with bearing block；Described adjusting bracket includes slide block, adjusting screw rod and knee；Described slide block coupling is slidably connected to the stage casing of described spatula and one end, the back side is provided with nut seat, and the middle part of described nut seat is provided with screwed hole；Described adjusting screw rod includes screw rod and spiro rod cap；The external screw thread matched with described screwed hole is offered on described screw rod；Described spiro rod cap is located at described screw rod one end, the other end of described screw rod through described bearing block and with described bearing block assembly connection；The screwed hole of the body of rod and described nut seat that described screw rod passes described bearing block is connected；Described adjusting screw rod rotates around described bearing block, and rotation torque is converted into described external screw thread and screwed hole the straight-line displacement of described slide block, so that described slide block presses the stage casing straight-line displacement of tongue frame along described opening.
Described Novel oropharynx operation gag, wherein: described slide block is rectangular structure, its positive Middle face offers chute along its length；Described slide block is mated with described spatula stage casing be slidably connected by described chute；The cell wall top, both sides of described chute all bends to described chute central authorities in 90 °, drops limiting described slide block from described spatula.
Described Novel oropharynx operation gag, wherein: described spatula bends from middle part, and its end and seamed edge are smooth streamline-shaped arc face structure.
Described Novel oropharynx operation gag, wherein: outside described spiro rod cap, be additionally provided with the friction rib preventing finger slippage.
Beneficial effect:
This utility model operation on oropharynx is simple with the design of gag structure, rationally, parts are few, low cost, when needing to adjust adjusting bracket position on opening pressure tongue frame, only need to rotate the spiro rod cap of adjusting screw rod, now adjusting screw rod can rotate around nut seat, and rotation torque turned the straight-line displacement being converted into slide block by the cooperation of screw rod and the screwed hole of nut seat, to realize slide block along opening pressure tongue frame stage casing slide displacement, finally adjusting bracket can be adjusted to correct position, ccavum oropharygeum visual area is fully exposed, it is beneficial to operation technique, operating time is made to shorten, hemorrhage minimizing, improve surgical effect and reduce operation risk.This structure design operation uses simple, convenient, laborsaving, can greatly reduce medical personnel's fatigue strength, improve medical personnel's work efficiency, the most beneficially patient treatment.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model operation on oropharynx gag；
Fig. 2 is the structural representation of the adjusting bracket of this utility model operation on oropharynx gag.
Detailed description of the invention
As shown in Figure 1, 2, this utility model operation on oropharynx gag, including opening pressure tongue frame 1 and adjusting bracket 2.
This opening pressure tongue frame 1 be structure as a whole, its two ends respectively to same lateral buckling and bending after wherein one end be spatula 11；This spatula 11 bends from middle part, and its end and seamed edge are smooth streamline-shaped arc face structure；Meanwhile, the stage casing outer wall of this opening pressure tongue frame 1 is additionally provided with bearing block 12 in the position near spatula 11 side.
This adjusting bracket 2 is installed on this opening pressure tongue frame 1, including slide block 21, adjusting screw rod 22 and knee 23；Wherein, this slide block 21 is in rectangular structure, and its positive Middle face offers chute 211 along its length, and one end, the back side is provided with nut seat 24, and the middle part of this nut seat 24 is provided with screwed hole 241；This slide block 21 is pressed spatula 12 stage casing of tongue frame 1 to mate by chute 211 with opening and is slidably connected；Meanwhile, the cell wall top, both sides of this chute 211 all bends in the middle part of chute 211 in 90 °, drops from spatula 12 limiting slide block 21.
This adjusting screw rod 22 includes screw rod 221 and is located at the spiro rod cap 222 of screw rod 221 one end；Offer the external screw thread that the screwed hole 241 with nut seat 24 matches on this screw rod 221, its one end through bearing block 12 and with bearing block 12 assembly connection, and then make screw rod 221 to rotate in a circumferential direction, it is impossible to axially displacement；Meanwhile, the screwed hole 241 of the body of rod and nut seat 24 that this screw rod 221 passes bearing block 12 is connected；This spiro rod cap 222 is provided with friction rib (increases frictional force, prevent finger slippage), when user rotates spiro rod cap 222 by hand, this screw rod 221 rotates under the effect of bearing block 12 and rotation torque is converted into external screw thread and screwed hole 241 slide block 21 straight-line displacement, so that slide block 21 is along opening pressure tongue frame 1 stage casing slide displacement.When needing to adjust the adjusting bracket 2 position on opening pressure tongue frame 1, only need to rotate the spiro rod cap 222 of adjusting screw rod 22, now adjusting screw rod 22 rotates around nut seat 24, rotation torque is turned the straight-line displacement being converted into slide block 21 by the cooperation of screw rod 21 and nut seat 24, to realize slide block 21 along opening pressure tongue frame 1 stage casing slide displacement, adjusting bracket 2 is adjusted to correct position the most at last.
This knee 23 takes the shape of the letter U bar structure, and its bar portion, one end is connected to slide block 21 back side near regulation forks piece 22 side, and other end bar portion is provided with parts 231 and is hung on central incisor.
The design of this utility model structure is simple, reasonable, operates with simple, convenient, laborsaving, reduces medical personnel's fatigue strength, improves medical personnel's work efficiency, beneficially patient treatment.
