Abstract
The utility model discloses a dental elevator, including grab handle, connecting rod and sword, the connecting rod including the lower connecting rod of connecting the grab handle and the last connecting rod of connecting the sword, go up the screw locking of connecting portion through running through of connecting rod and lower connecting rod. The utility model has the advantages of reduced medical instrument's input cost, dental elevator angle wantonly buckles, can adapt to any position tooth and use to convenient to use, simple structure, reliable.
Description
Technical field
This utility model relates to type medical instrument for dental use.
Background technology
Dental elevator is one of exodontia instrument, for dental elevator is loose, to facilitate extracting of tooth before exodontia.Dental elevator is made up of sword, handle and bar three part.The bending angle of current dental elevator sword is fixed, it is impossible to adjust, and therefore for the diverse location of operation, needs to be equipped with the dental elevator of different bending angle.
Utility model content
Technical problem to be solved in the utility model be realize a kind of can the dental elevator of angle-adjustable.
To achieve these goals, the technical solution adopted in the utility model is: dental elevator, including lever, connecting rod and sword, described connecting rod includes the lower link connecting lever and connects the upper connecting rod of sword, and the connecting portion of described upper connecting rod and lower link is by the screw locking run through.
Described connecting portion includes the first affixed with connecting rod two parts respectively contiguous block and the second contiguous block, the first described contiguous block is provided with the hole run through for screw, and outside described first contiguous block, it being provided with the counterbore placing screw, described second contiguous block is provided with the internal thread hole fixing for screw.
It is as the center of circle and to be equally spaced around hole or the burr of internal thread hole setting and dimpled grain structure with hole or internal thread hole that the first described contiguous block and the second contiguous block forward surface are provided with the tooth and groove cooperated, described tooth and groove.
The utility model has the advantage of the input cost reducing medical apparatus and instruments, dental elevator can arbitrarily angled bend, and is adapted to any position tooth and uses, and easy to use, simple in construction, reliable.
Accompanying drawing explanation
Labelling in the content expressed every width accompanying drawing in this utility model description below and figure is briefly described:
Fig. 1 is dental elevator structural representation；
Fig. 2 is the blade portion structural representation of dental elevator；
Labelling in above-mentioned figure is: 1, lever；2, connecting rod；3, sword；4, connecting portion.
Detailed description of the invention
Dental elevator includes lever 1, connecting rod 2 and sword 3, as Fig. 1 connecting rod 2 includes the lower link connecting lever 1 and connects the upper connecting rod of sword 3, connecting rod 2 is divided into two independent parts, and the connecting portion 4 of upper connecting rod and lower link is by the screw locking run through, such that it is able to angle-adjustable.
Connecting portion 4 includes the first affixed with connecting rod 2 two parts respectively contiguous block and the second contiguous block, first contiguous block is provided with the hole run through for screw, and first be provided with the counterbore placing screw outside contiguous block, can ensure that screw is accommodated in connecting portion 4 by counterbore, patient skin will not be scratched in use, second contiguous block is provided with the internal thread hole fixing for screw, internal thread hole and screw fit.The thickness of the first contiguous block and the second contiguous block is the half of connecting rod 2 thickness, makes connecting rod 2 in an overall structure, only bend at connecting portion 4 after overlapped rear locking.
Owing to dental elevator uses stress bigger, therefore movable connection structure must be reliable, therefore it is provided with, at the first contiguous block and the second contiguous block forward surface, the tooth and groove cooperated, tooth is burr, groove is dimpled grain (such as Fig. 2), i.e. first contiguous block is provided with tooth, second contiguous block is provided with groove, or the second contiguous block is provided with tooth, first contiguous block is provided with groove, tooth and groove are as the center of circle and to be equally spaced around hole or the burr of internal thread hole setting and dimpled grain structure with hole or internal thread hole, burr and dimpled grain can be straight lines, dots structure, camber line etc., so after connecting portion 4 any rotation, only need tooth and groove engaging, tighten screw again, then can guarantee that the dependability of dental elevator.
Above in conjunction with accompanying drawing, the present invention is exemplarily described; obviously this utility model implements and is not subject to the restrictions described above; if the improvement of the various unsubstantialities that the method design that have employed the present invention is carried out with technical scheme; or the most improved design by the present invention and technical scheme directly apply to other occasion, all within protection domain of the present utility model.
Claims (2)
1. dental elevator, including lever, connecting rod and sword, it is characterised in that: described connecting rod includes the lower link connecting lever and connects the upper connecting rod of sword, and the connecting portion of described upper connecting rod and lower link is by the screw locking run through；
