The traction main body and the vertebral body distraction screw which is placed in the cervical vertebral body can be rotationally connected, so that a rotary supporting point can be provided for the traction main body, and the operation of auxiliary personnel is more convenient, labor-saving, safe and effective; in addition, only one auxiliary personnel is needed to pull the tissues in the area to be operated, so that the labor is saved.
Description
Technical field
The utility model relates to cervical operation appurtenances, and in particular to a kind of cervical operation outside drag hook.
Background technique
In cervical operation, in order to expose affected part and carry out local treatment, the tissue of cervical vertebra front is pulled frequently with drag hook,
Such as: oesophagus, tracheae, arteria carotis etc..Existing drag hook is made frequently with plate bending, in the process of drawing cervical vertebra front tissue
In, it needs multi agent cooperation and to multiple directions while pulling.Existing drag hook in use, has the disadvantages that 1) entire
In operation, more assist personnel need to be configured；2) when medical staff pulls cervical vertebra front tissue, firmly size is not
One, easy overexertion causes to tear tissue, and (damage oesophagus, tracheae cause esophageal fistula, tracheal fistula, and damage arteria carotis causes to go out greatly
Blood threat to life)；3) existing drag hook narrower width, vital tissue, artery, vein etc. easily from the bulging of drag hook two sides, cause doctor source
Property damage, such as cause esophageal fistula, tracheal fistula and arteria carotis, jugular vein damage, period in hospital and hospitalization and medical treatment expenses will be significantly increased
With；4) drag hook easily slides into important operative region in art, stops the visual field of operator, influences procedure.
Utility model content
The purpose of this utility model is to provide a kind of cervical operation outside drag hooks, to solve to mention in above-mentioned background technique
And when being organized using existing drag hook drawing cervical vertebra front, need to configure more assist personnel, cause manpower unrestrained
The problem of taking；Existing drag hook is not fixed and narrower width, causes excessively to tear tissue, iatrogenic injury and stops the operator visual field
The problem of influencing procedure.
To achieve the above object, the utility model provides the following technical solutions: a kind of cervical operation outside drag hook, including
It is arranged in the drawing main body that cervical vertebra waits for operative region, one end end of the drawing main body is provided with the vertebra with merging cervical vertebral body
Body struts the articulation port that screw matches, which is engaged on the bared end of the pyramidal support screw, the drawing master
Body is rotated around biting point, pushes the tissue to operative region, exposure operating field aside.
Further, handle is additionally provided in the drawing main body, described handle one end is fixed in the drawing main body,
The other end is stretched out to operative region；The drawing main body is driven by the handle and is rotated around biting point.
Further, the handle is located at ipsilateral in the drawing main body with articulation port.
Further, the handle is fixed in the drawing main body by connecting plate, and the handle where plane with
Plane where the drawing main body is vertical.
Further, the drawing main body is the smooth plate structure in surface, and the length of the drawing main body is by wait perform the operation
The cervical vertebral body height in region determines.
Further, the drawing main body is additionally provided with the wavy sawtooth of a row in the long side of cervical vertebral body.
Further, the handle and drawing main body are all made of hard material production.
Compared with prior art, the utility model has the beneficial effects that
(1) it using the rotatable connection type of pyramidal support screw of drawing main body and merging cervical vertebral body, can be led
The supporting point of main body one rotation is drawn, so that support staff operates enhanced convenience, laborsaving, safely, effectively；Furthermore, it is only necessary to one
A support staff can both push the tissue to operative region aside, save manpower；It pulls main body and is placed in the centrum support of cervical vertebral body
It opens screw to be mutually twisted, is not easy to slide into important operative region, influences the operator visual field；The width for pulling main body is wide, vital tissue
And arteria carotis is not easy that bulging is external to lead to iatrogenic injury；
(2) when the handle rotates and the drawing main body is driven to pull tissue to certain position, operator only needs to see
It examines whether handle rotates, main body is pulled to the drawing dynamics of tissue to adjust with this, can effectively reduce and artificially excessively lead
The problem of drawing；
(3) the waveform sawtooth in the drawing main body, can push together the tissue being close proximity on cervical vertebra aside, can will perform the operation
Open country is handled more clean, convenient for the operation of subsequent procedures.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- arteria carotis, 2- pull main body, 3- sawtooth, 4- connecting plate, 5- handle, 6- articulation port, 7- pyramidal support spiral shell
Nail.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, described embodiment is only a part of the embodiment of the utility model, rather than all
