Abstract
The utility model discloses a bone chisel inside zygomatic arch, including a control handle (1), a control level (2), a chisel pillar (3) and a chisel head (4). The utility model is an improved one to the chisel adopted in operations on malar and zygomatic arch, so its chisel head is a shovel-like structure bending inward with a U-blade (5). The bulges (6) on both ends of the U-blade (5) are obtuse angles and the blade incline (7) is made outwardly. Therefore, the instrument can be used to fundamentally accomplish amputation on malar and zygomatic arch in such operations, that is, it can enter via oral cavity to perform amputation, thus ensuring from impairment of the soft tissue and important anatomical structure. It is easy to use and a surgeon can, while performing amputation, maintain the symmetry of the amputating lines on both sides and fundamentally ensure the symmetry in terms of the remained bone quantity on both sides of malar and zygomatic arch after amputation.
Description
Technical field
This utility model relates to a kind of people's maxillofacial bone treatment equipment, particularly relates to the inboard osteotome of a kind of zygomatic arch at the zygoma treatment.
Background technology
At present, knownly adopt from the beginning apical cap shape otch approach or preauricular incision approach osteotomy to add internal fixation treatment again at the zygomatic arch bone-culting operation more.Because how the traditional osteotome osteotomy of the many employings of operation can be damaged surrounding soft tissue and important anatomical structure in the operation, and can stay the operation cicatrix outside skin.
Summary of the invention
In order to overcome the deficiencies in the prior art part; this utility model discloses a kind ofly can protect zygoma portion soft tissue well; be convenient to the doctor and carry out inboard osteotomy operation at zygoma safely and effectively, promptly carry out the inboard osteotome of zygomatic arch of osteotomy operation from oral approach.
The technical solution of the utility model is achieved in that the inboard osteotome of a kind of zygomatic arch comprises control crank, stick, cutter pier and cutter head, described cutter head be one aduncate, have the spade structure of u blade blade.The projection at described u blade blade two ends is the obtuse angle, and the u blade edge bevel toward the outer side.Described control crank, stick, cutter pier and cutter head are overall structures, are made by metal material.
The beneficial effects of the utility model are: because this utility model improves the osteotome that is adopted in the existing zygoma operation; its cutter head be one aduncate; the spade structure that has the u blade blade; carry out osteotomy promptly when oral approach carries out osteotomy so can fundamentally solve in zygoma operation, protect soft tissue and important anatomy structure injury-free at zygoma.It is convenient to operation, can make the doctor in osteotomy, keeps the symmetry of bone amount after keeping the symmetry of bilateral osteotomy line and fundamentally guaranteeing bilateral zygoma osteotomy.
The utility model is described in further detail below in conjunction with accompanying drawing for description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, the inboard osteotome of zygomatic arch of the present utility model comprises control crank 1, stick 2, cutter pier 3 and cutter 4, described cutter 4 be one aduncate, have the spade structure of u blade blade 5.The projection 6 at described u blade blade 5 two ends is the obtuse angle, and u blade edge bevel 7 toward the outer side.Described control crank 1, stick 2, cutter pier 3 and cutter 4 is overall structures, made by metal material.Described cutter 4 curves inwardly angular range between 100-160 ° of degree.The width of described u blade blade 5 is between the 5-15 millimeter.
Claims (5)
1. the inboard osteotome of a zygomatic arch comprises control crank (1), stick (2), cutter pier (3) and cutter head (4), it is characterized in that: described cutter (4) be one aduncate, have the spade structure of u blade blade (5).
2. the inboard osteotome of zygomatic arch according to claim 1 is characterized in that: the projection (6) at described u blade blade (5) two ends is the obtuse angle, and u blade edge bevel (7) toward the outer side.
