Abstract
The utility model patent is a kind of maxillary osteotomy cheek tractor, including tractor head (1), Reversal retractor portion (2), positive drag hook portion (3), handle portion (4), handle (4a), groove (4b).The cheek tractor is the bar of edge round blunt；The tractor head (1) is against at maxilla back maxillary tuberosity or descending lamina of sphenoid bone, while consolidating, is laborsaving, avoids damage to the wing clump at maxilla rear；The Reversal retractor portion (2), positive drag hook portion (3) are adapted with maxilla back and lip cheek soft tissue shape respectively, while fully exposing the maxillary osteotomy visual field, avoid damage to lip cheek soft tissue；Handle portion (4) surface increases when holding and the frictional force of palm there are groove, is held for a long time with facilitating.The utility model patent exposes surgical field of view when performing the operation for maxilla back, fully exposure maxilla back surgical field of view while, noninvasive, firm drawing lip cheek soft tissue is simple structure, easy to use, has good economic and social benefit.
Description
Technical field
The utility model is related to a kind of maxillary osteotomy cheek tractor more particularly to a kind of it can pull lip and cheek soft tissue
Fully to expose the cheek tractor of maxilla back.
Background technology
Currently, well known cheek tractor is formed by connecting by the drag hook portion of bending and the handle portion of gripping, drag hook portion is by just
To and/or reversed arc-shaped bend tablet composition, buccal soft tissue can be pulled, to expose operative region.However, these
Design has the following problems and disadvantage：1. tractor head cannot protect important deep vessels and nerve well；2. drag hook portion
Arc-shaped bend cannot be well adapted for the shape of maxilla back maxillary tuberosity and cheekbone alveolar ridge and lip cheek soft tissue simultaneously；3.
Drag hook portion is tablet, although edge round blunt, drawing can still damage lip cheek soft tissue for a long time；4. handle portion be tablet or
Thinner bar, it is difficult to hold for a long time.
Invention content
Invention the purpose of this utility model is against the above deficiency, to provide a kind of maxillary osteotomy cheek tractor.
Realizing the technical solution of the utility model aim is：A kind of maxillary osteotomy cheek tractor, it is characterised in that：Institute
It states maxillary osteotomy to be linked in sequence by tractor head, Reversal retractor portion, positive drag hook portion and handle portion with cheek tractor, lead
It is the bar of edge round blunt to draw device, and tractor head can be against at maxilla back maxillary tuberosity or cheekbone alveolar ridge, to expand hand
The art visual field and the blood vessel and nerve for preventing damage maxilla back important；The radian in Reversal retractor portion and maxilla back upper jaw knot
Shape at section or cheekbone alveolar ridge is consistent, preferably to expose maxilla back；The radian in positive drag hook portion and lip cheek soft tissue
Shape it is consistent, with preferably noninvasive drawing lip cheek soft tissue；Handle portion is bar with groove, is held with facilitating.
The tractor head is the aduncate bar of end round blunt, long 0.5cm, wide 1.5cm, thick 0.4cm, tractor
Head is against at maxilla back maxillary tuberosity or descending lamina of sphenoid bone, consolidates, is laborsaving, and avoiding damage to the wing clump at maxilla rear.
The Reversal retractor portion be edge round blunt, arc fold bending bar, long 4.0cm, wide 1.5cm, thick 0.4cm,
Radian is consistent with the shape at maxilla back maxillary tuberosity or cheekbone alveolar ridge, stops maxilla lip buccal side soft tissue, can be in office
Portion forms the surgical field of view of 45 ° -50 ° of abduction.
The forward direction drag hook portion be edge round blunt, arc fold bending bar, long 3.5cm, wide 1.5-1.8cm, thick 0.4-
0.6cm, from positive drag hook portion and Reversal retractor portion junction, positive drag hook portion HOMOGENEOUS BROADENING thickeies, radian and soft group of lip cheek
Shape adaptation is knitted, pulls lip cheek soft tissue, while avoiding damage to lip cheek soft tissue.
The handle portion is arc-shaped bar, long 4.0cm, wide 2.0cm, thick 0.8cm, table groove on panel surface, groove depth
0.2cm, increase hold when and palm frictional force, with facilitate for a long time hold.
Due to the utility model using the tractor head of the aduncate bar of end round blunt, radian and corresponding drawing or
The structure of the adaptable forward and reverse drag hook portion of exposure tissue and the handle portion with groove for facilitating gripping, so as to obtain with
Lower advantageous effect：It is abundant exposure the surgical procedure visual field while, facilitate for a long time, it is noninvasive, steadily pull lip cheek soft tissue,
Simple in structure, operation is easy.
Description of the drawings
The utility model is described in further detail below in conjunction with attached drawing.
Fig. 1 is a kind of side view of maxillary osteotomy cheek tractor of the utility model.
Fig. 2 is the sectional view of handle portion shown in Fig. 1.
Main components explanation in figure：1. tractor head, 2. Reversal retractor portions, 3. positive drag hook portions, 4. handle portions, 4a.

Specific implementation mode
In the embodiment shown in fig. 1, tractor head 1, which is against, is further illustrated to the utility model below in conjunction with the accompanying drawings
At jawbone rear portion maxillary tuberosity or descending lamina of sphenoid bone, while consolidating, is laborsaving, the wing clump at maxilla rear is avoided damage to；It is reversed to draw
2 radian of hook portion is consistent with the shape at maxilla back maxillary tuberosity or cheekbone alveolar ridge, stops maxilla lip buccal side soft tissue；Just
It is adapted to 3 radian of drag hook portion and lip cheek soft tissue shape, edge round blunt, drawing lip cheek soft tissue fully exposes the same of surgical field of view
When, avoid damage to lip cheek soft tissue；It is hold by one hand in handle portion 4, the presence of groove 4b increases frictional force, facilitates and holds for a long time
It holds.
