Description

Multifunctional combination Wicresoft Exelcymosis knife

Technical field

This utility model relates to a kind of medical apparatus and instruments, and particularly one has multifunctional combined Wicresoft Exelcymosis knife (Minimally invasive tooth knife).

Background technology

Wicresoft's Exelcymosis knife is invented by external dental professional and is designed the earliest, and its structure comprises three parts: blade, knife bar and handle.Wicresoft's Exelcymosis knife is between dental elevator and mount emei cutter, sharper than dental elevator, and the handle that can exert oneself more than mount emei cutter, therefore, occupation mode and the current domestic conventional exodontia instrument of Exelcymosis knife are had any different.Use Exelcymosis knife to carry out tooth extraction procedure, do not need to use hammering to increase gap, the level of comfort of patient is improved greatly.Exelcymosis knife exodontia is used to be revolutionary from this aspect.

Along with the develop rapidly of Medical Technology, the kind of Wicresoft's Exelcymosis knife gets more and more.But, the work efficiency that Exelcymosis knife model not only reduces dentist is constantly changed in the arrachement of complicated teeth, and require that medical space has Wicresoft's Exelcymosis knife of enough models and quantity, there are these apparatuses of enough space, this not only adds the cost of dental instruments, sterilizing works too increases the cost of manpower and sterilization frequently, how to improve exodontia doctor work efficiency, reduce dental instruments and sterilizing cost most important for the design of Wicresoft's Exelcymosis knife.

Summary of the invention

Many in order to overcome common Wicresoft Exelcymosis knife quantity, handle takes up space greatly, and sterilizing frequency is high, the problem that cost is high, this utility model provides a kind of multifunctional combination Wicresoft Exelcymosis knife, and this Exelcymosis knife can reduce the space that handle occupies greatly, reduces the cost of dental instruments and sterilizing.

This utility model solves the technical scheme that its technical problem adopts: blade and knife bar one, knife bar can become straight type or curved, the top of some knife bars is respectively equipped with the blade of different model, be movably connected on handle, with loop bar on handle, during use, knife bar inserts and is fixed on handle by finger sliding loop bar.Without the need to changing handle in Wicresoft's tooth extraction procedure, only need more changing knife rod to complete operation technique, the time is short, and efficiency is high, and patient suffering is few, convenient and swift, safe and reliable.

The beneficial effects of the utility model are, can be used for all kinds of trouble tooth, to be completely cured and the Wicresoft of undesirable root pulls out, decrease the input of dental instruments, saved medical resource, reduce manpower and sterilizing cost.Method for designing is simple, is easily grasped by user.

Detailed description of the invention

In FIG, loop bar (5) is seated on bar in handle (8) by screw (6), can slide up and down at screw hole (7) place simultaneously.

In fig. 2, steel ball (10) diameter is 1.3 times of steel ball hole (2) thickness, and steel ball hole (2) external diameter is slightly larger than steel ball (10) diameter, and internal diameter is 4/5 of steel ball (10) diameter.Steel ball (10) is positioned at steel ball hole (2) and can charges into knife bar path of insertion (11), but can not come off.

In the embodiment of shown in Fig. 1, card (3) in spring (4) upper-end contact loop bar, bar (8) in lower end in contact handle, finger pressure loop bar (5) slides to handle (9) direction, spring (4) compresses, steel ball (10) slides to card (3) outside in loop bar, now insert the knife bar (1) in Fig. 7, after knife bar groove (13) and tail end (14) are located in the knife bar path of insertion (11) in Fig. 2, finger unclamps loop bar (5), loop bar (5) returns to original position, steel ball (10) slides to card (13) place in loop bar and charges into and coincide with the knife bar groove (13) in Fig. 7 to the knife bar path of insertion (11) in Fig. 2, thus the knife bar in Fig. 7 (1) is seated on handle (9).

In another embodiment shown in Fig. 1, point to handle (9) direction pressing loop bar (5), spring (9) compresses, steel ball (12) slides to card (3) outside in loop bar, now can extract the knife bar (1) in Fig. 7, more changing knife rod, unclamp finger, loop bar (5) returns to original position.
