Goitre retractor adopted name: right-angle retractor is made of inner sheet and outer plate.Right-angle retractor for drawing abdominal cavity wound,
The tissues such as appendix, internal organ or thyroid gland are used.
The drag hook that oromaxillo-facial operation is routinely equipped with is goitre retractor, but due to the complexity of Maxillary region anatomical structure
Property, in the clinical use of some Maxillary region deep operations, it is commonly present the insufficient situation of exposed operating field；Because of its coupler body, hand
The straight line of handle etc., right-angle design easily generate compressing and damage to Maxillary region especially deep soft tissue；Also single because of its structure
Property, so that patient is generated fatigue when long-time uses.
Need it is a kind of it is applied widely, conducive to exposure surgical field of view in Maxillary region deep operation, facilitate operation, be easy to encircle
Deep tissue avoids damage to, the maxillofacial operation drag hook that comfort is good.
Utility model content
The purpose of the utility model is to provide a kind of applied widely, views of performing the operation conducive to exposure in Maxillary region deep operation
Open country facilitates operation, is easy to encircle deep tissue, avoid damage to, the maxillofacial operation drag hook that comfort is good.
A kind of maxillofacial operation drag hook, comprising:

Hook item and connecting rod are linked together, and the connecting rod is identical with the opening direction of coupler body, the coupler body laterally along the first hook
Item, second hook item and third hook item are sequentially increased, and for sector, the transverse direction of the coupler body is arc groove, the opening of the arc groove
The opening direction of direction and connecting rod is opposite.
The handle is made of the first gripper rings and the second gripper rings, and first gripper rings are class vesica piscis, described
Second gripper rings are annulus.
Second gripper rings are close to connecting rod.
The handle, connecting rod and coupler body are integral type, and longitudinal is bar shaped.
The center line of the handle, connecting rod and coupler body is coplanar, and respectively about the plane mirror symmetry.
Angle between the coupler body and the connecting rod of arc is obtuse angle.
The utility model handle is the sheet of hollow out；Connecting rod is arc strip, and both ends are separately connected handle and coupler body；Coupler body
Longitudinal is U-lag shape, and by the first hook item, second hook item and third hook item composition, the first hook item and connecting rod are linked together, and is connected
Bar is identical with the opening direction of coupler body, and coupler body is sequentially increased laterally along the first hook item, second hook item and third hook item, for fan
The transverse direction of shape, coupler body is arc groove, and the opening direction of arc groove and the opening direction of connecting rod are opposite.Coupler body by connecting rod with
Handle connection, the angle between coupler body and the connecting rod of arc is obtuse angle, and coupler body is designed to up-narrow and down-wide sector structure, and
It is designed as top-down arc-shaped recess in its cross section, preferably to expose it in the lesser maxillofacial operation of notch
The surgical field of view in deep.The arc dog-ear of coupler body end can be easier to encircle deep tissue.Connecting rod similarly sets for arc
Meter is designed compared to traditional line type, under the premise of not influencing visual area exposure, is effectively reduced to each region of anatomy of Maxillary region
The unnecessary compressing of hard and soft tissue, avoids damage.The utility model is applied widely, is conducive to exposure in Maxillary region deep operation
Surgical field of view, facilitate operation, be easy to encircle deep tissue, avoid damage to, comfort it is good.
