Abstract

The utility model particularly relates to a directional bone chisel for molar teeth, which resolves the problem that an existing bone chisel cannot be accurately positioned in an operation process and is stopped by soft tissues of corners of the mouth of a patient when operated in a molar tooth area. The directional bone chisel for molar teeth comprises a chisel handle and a chisel blade, the middle section of a chisel rod between the chisel handle and the chisel blade is an arc-shaped chisel rod, a groove is arranged on a side surface of a straight chisel rod between the arc-shaped chisel rod and the chisel blade, a dial plate shaft which can rotate and slide in the groove and is perpendicular to the side surface of the straight chisel rod is clamped in the groove, a fan-shaped double-surface angle dial plate is fixedly sleeved at the outer end of the dial plate shaft, a pointer which is fixed on the straight chisel rod along a center line of the groove and can vertically slide is arranged right above the double-surface angle dial plate, and angle graduation lines are carved on the double-surface angle dial plate. The directional bone chisel for molar teeth is exquisite in design, is simple and practical, and reduces difficulty of dental crown splitting, dental root separating and the like during molar tooth operation in oral tooth extraction surgery.

Description

The directed osteotome of backteeth

Technical field

This utility model relates to the osteotome in the oral cavity medical apparatus, is specially the directed osteotome of a kind of backteeth.

Background technology

In the oral surgery tooth pulling surgery, often run into backteeth and split operations such as hat, root division, at present clinical in employed osteotome two-sided osteotome, single face osteotome, semicircle osteotome, knife face osteotome etc. are arranged.But existing osteotome exists not enough, is specially osteotome force direction in operating process and is difficult for confirming that operation can't accurately be located; When operating in the backteeth district, osteotome receives bicker district soft tissue to be stopped, has a strong impact on angle and surgical field of view that osteotome is placed.

Summary of the invention

The location was inaccurate and be vulnerable to the problem that bicker district soft tissue stops when this utility model used in order to solve existing osteotome, provided a kind of backteeth directed osteotome.

This utility model is to adopt following technical scheme to realize: the directed osteotome of backteeth; Comprise cutter handle, chisel edge; Cutter bar stage casing between cutter handle and the chisel edge is an arc cutter bar; Straight shape cutter bar side between arc cutter bar and the chisel edge has groove, in the groove card have with straight shape cutter bar lateral vertical and in groove not only rotatable but also dial plate axle slidably, intrinsic segmental dihedral angle kilsyth basalt dish is overlapped in dial plate axle outer end; Be provided with directly over the dihedral angle kilsyth basalt dish and be fixed on the straight shape cutter bar and the pointer that can slide up and down along the centrage of groove, drawing on the dihedral angle kilsyth basalt dish has the angle index line.The fit of groove and two-sided dial plate axle had both guaranteed the secure fixation of axle, can adjust simultaneously position and the angle of axle in groove again, and this is that those skilled in the art realize easily.During clinical use; Measure the osteotome that to split hat when impacted tooth is pulled out according to X-ray film before the art and place angle; And show according to X-ray film and need pull out backteeth root of the tooth bifurcated degree size, confirm the reasonable angle of osteotome root division, confirm to split in the time of can guaranteeing to have tooth pulled out the optimum orientation of hat, root division with upper angle; During operation; At first with stable being put on tooth development ditch or the root difference top tooth body of the directed osteotome chisel edge of backteeth; Regulate the high and low position of dial plate axle in groove then; Guarantee that dihedral angle kilsyth basalt dish one side gulde edge steadily is put on the adjacent jaw, and the height of adjustment pointer, it is comparatively approaching to make pointer leave the distance of dihedral angle kilsyth basalt dial scale; Under the fixed situation of dihedral angle kilsyth basalt dish, rotate its direction of osteotome adjustment at last, make the angle of pointer on dihedral angle kilsyth basalt dish one side gulde edge and the osteotome, wait the preceding measured best angle value of X-ray film of Rhizoma Atractylodis Macrocephalae, with the degree of accuracy that guarantees that osteotome is directed required; Split operations such as hat, root division in ready can the exodontia.When pulling out the backteeth operation technique, the arc cutter bar protrusion direction of the directed osteotome design of backteeth is towards the outside, oral cavity, fully dodges bicker district soft tissue to the stopping of osteotome, and is clear to guarantee correct direction and surgical field of view that osteotome places.

The beneficial effect of this utility model is following: be utilized in dihedral angle kilsyth basalt dish and arc cutter bar are set on the osteotome; When having realized pulling out backteeth; The best accurately direction of osteotome in splitting hat, root division confirmed; And the design of arc cutter bar can fully be dodged bicker district soft tissue to the stopping of osteotome, guarantees that correct direction and surgical field of view that osteotome places are clear.This utility model deft design, simple and practical has reduced and has split the difficulty in the backteeth operation such as hat, root division in the tooth pulling surgery of oral cavity.

The specific embodiment

The directed osteotome of backteeth; Comprise cutter handle 1, chisel edge 5; Cutter bar stage casing between cutter handle 1 and the chisel edge 5 is an arc cutter bar 2; Arc cutter bar 2 has groove 6 with straight shape cutter bar side between the chisel edge 5, and card has and not only turned with straight shape cutter bar lateral vertical and in groove 6 but also dial plate axle 4 slidably in the groove 6, and intrinsic segmental dihedral angle kilsyth basalt dish 3 is overlapped in dial plate axle 4 outer ends; Be provided with directly over the dihedral angle kilsyth basalt dish 3 and be fixed on the straight shape cutter bar and the pointer 7 that can slide up and down along the centrage of groove 6, drawing on the dihedral angle kilsyth basalt dish 3 has the angle index line.

In the specific embodiment; The directed osteotome length overall of backteeth is 170mm, cutter handle 1 long 85mm, and the air line distance between the two ends end points of arc cutter bar 2 is 60mm; The central top of arc cutter bar 2 arcs is 15mm apart from the vertical dimension of line between its two ends end points; And the center of gravity that makes the directed osteotome of backteeth is on the extended line of the centrage of groove 6, and it is the fan-shaped dial plate of 120 degree that dihedral angle kilsyth basalt dish 3 uses total angle, and the angle on the dihedral angle kilsyth basalt dish 3 is expressed as whenever at a distance from standardized long graduation mark of 10 degree.This degree of accuracy is the confirming of directional angle in the tooth pulling surgery of oral cavity enough, can between two long graduation marks, add like the more accurate angle of need and draw more low-angle short graduation mark, improves degree of accuracy.
