The dedicated osteotome of dentistry implant operation of the utility model embodiment is described in detail with reference to the accompanying drawings.

As shown in Figure 1 to Figure 3, according to the dedicated osteotome of dentistry implant operation of the utility model embodiment comprising handle 20 and the chisel 10 that is fixedly linked with the handle 20.

Specifically, the chisel 10 includes that lower end is connected and chisel bar 11 cylindrical with the handle 20, the chisel bar 11 upper end end rolls unsymmetrical bending backward and forms chisel head 12, and the front side of the chisel head 12 has one to be used to form chisel edge 122 Preceding chisel face 121.That is, the upper part that the chisel head 12 of the present embodiment is chisel bar 11 is needed to be cut into after being bent by setting Type, the section after cutting is the preceding chisel face 121.In this way, the dedicated osteotome of dentistry implant operation using the present embodiment can be more Add convenient progress pelvic radiograph operation or chisel the bone tissue for being wrapped in bone regeneration around implant, sufficiently to expose planting body.

Further, as shown in figure 3, the angle between the central axis of chisel head 12 and the central axis of the chisel bar 11 is 5-15°.That is, the angle is the bending angle of chisel head 12, such design structure during dentistry implant operation, The operation of doctor can be easily facilitated, while being more conducive to the operation of the pelvic radiograph in implant operation.

Preferably, the preceding chisel face 121 is plane, and the angle with the central axis of the chisel head 12 is 1-5 °.Such as This, is formed by chisel head 12 by the preceding chisel face 121 and sees that such structure can in gradually wide structure from top to bottom in side-looking direction Convenient for the reaming work in pelvic radiograph is performed the operation.

In one embodiment of the utility model, as depicted in figs. 1 and 2, the preceding chisel face 121 is equipped with a cross section For the groove 123 of arc, the upper end of the groove 123 extend to at the chisel edge 122.In this way, the wall of chisel head 12 can be reduced Thickness, in order to be more easier when carrying out pelvic radiograph knock in chisel head 12 and alveolar bone of riving.

In one embodiment of the utility model, as shown in connection with fig. 4, the chisel head 12 has and the preceding chisel face 121 Opposite arcwall face 124, the upper end rear side of the arcwall face 124 dig face 125, dig face 125 and the preceding chisel after described after being equipped with The chisel edge 122 is collectively formed in face 121.Preferably, the rear chisel face 125 is plane, the central axis with the chisel bar 11 It is parallel.Design structure in this way is formed by the work of riving that chisel edge 122 easily facilitates osteotome.

In one embodiment of the utility model, the upper end of the arcwall face 124 is respectively arranged on the left side and the right side side chisel face 126.Specifically, two sides chisel face 126 is bent to 122 direction of chisel edge respectively, so that the chisel edge to be formed 122 be made to be more conducive to splitting Open alveolar bone.

In one embodiment of the utility model, the lower end of the chisel bar 11 has the company fixed with the handle 20 Socket part 13, the diameter of the interconnecting piece 13 are greater than the diameter of the chisel bar 11, and between the interconnecting piece 13 and the chisel bar 11 It is formed with rotary table portion 14.In this way, while chisel 10 and 20 bonding strength of handle can be improved, the self-strength of enhancing chisel bar 11, Make osteotome be unlikely to be easily deformed bending in pelvic radiograph operation, prolongs the service life.

In some embodiments of the utility model, the cross section of the handle 20 is regular polygon, and upward by lower end Setting is gradually reduced in end.Specifically, surgical handle 20 is the hollow handle 20 being made of stainless steel, and 20 upper end of handle It is that fixing sleeve is set on the interconnecting piece 13 of chisel 10；And the cross section of handle 20 is more convenient in hand using regular polygon structure Handle 20 exerting oneself and holding.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, It is all under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes It changes, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
