Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to coronal plane angulation swing saw for maxillofacial surgery.
Background
Whether the human angle of mandible is protruding and protruding big or little direct decision face shape, often will cut the bone to the angle of mandible in human face medical cosmetology at present and handle, the instrument that current osteotomy used is mainly the swing saw, and its structure is: the surgical instrument is characterized by comprising a cylindrical saw rod, wherein the length of the saw rod is 60-70 mm, a flat saw blade is fixed at one end of the saw rod, an included angle formed by the plane of the saw blade and the central line of the saw rod is a right angle, sawteeth are arranged on the periphery of the saw blade, and the saw blade is inserted into the oral cavity of a surgical object by utilizing an instrument clamping support rod (or a handheld support rod) and is used for cutting off the angle of the mandible. However, existing oscillating saws are difficult to achieve oblique resection due to size limitations of the mouth, such as being affected by the teeth.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the present invention provides a coronal angulation swing saw for maxillofacial surgery, which overcomes the technical problems existing in the background art.
In order to solve the technical problem, the utility model discloses a technical scheme be:
the coronal angulation swing saw for the maxillofacial surgery comprises a saw rod and a saw blade, wherein one side of the saw blade is connected to the saw rod, and the other side of the saw blade is provided with saw teeth;
the saw blade is a sheet-shaped body and comprises a contrast surface and a rotating shaft, and one end of the rotating shaft penetrates through the central shaft of the saw rod; the rotating shaft is a part of the contrast surface, the rotating shaft is vertical to the central shaft of the saw rod, and the included angle between the central shaft of the saw rod and the contrast surface is 10-20 degrees.
The beneficial effects of the utility model reside in that: the included angle between the saw blade and the central axis of the saw rod is 10-20 degrees, so that the oblique (angled) resection of the mandible angle can be realized under the condition of not changing the insertion angle of the saw rod, and the flexibility of the operation is enhanced.

description of reference numerals: 1. a saw bar; 11. a central shaft; 2. a saw blade; 21. saw teeth; 22. a contrast surface; 23. a rotating shaft.
Detailed Description
In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
Referring to fig. 1 and 2, the coronal plane angulation swing saw for maxillofacial surgery of the present invention comprises a saw bar 1 and a saw blade 2, wherein one side of the saw blade 2 is connected to the saw bar 1, and the other side thereof has saw teeth 21;
the saw blade 2 is a sheet-shaped body and comprises a contrast surface 22 and a rotating shaft 23, and one end of the rotating shaft 23 penetrates through the central shaft 11 of the saw rod 1; the rotating shaft 23 is a part of the comparison surface 22, the rotating shaft 23 is perpendicular to the central axis 11 of the saw bar 1, and the included angle between the central axis 11 of the saw bar 1 and the comparison surface 22 is 10-20 degrees.
As can be seen from the above description, by making the angle between the saw blade 2 and the central axis 11 of the saw bar 1 be 10 ° to 20 °, it is possible to perform oblique (angled) resection of the mandibular angle without changing the insertion angle of the saw bar 1, thereby enhancing the flexibility of the operation.
Further, the saw blade 2 is fan-shaped, and the tip end of the saw blade 2 is connected with the saw rod 1; the teeth 21 are arranged on the edge of the blade 2 where the arc length is located.
Furthermore, the included angle between the central axis 11 of the saw rod 1 and the contrast surface 22 is 15 DEG
Further, the height of the saw blade 2 is 18 mm.
Further, the diameter of the saw rod 1 is 2.5mm, and the length is 80 mm.
