Description
Technical field
The utility model relates to drag hooks between a kind of assembly type multipurpose transverse process, belong to medical surgical instrument field.
Background technique
Posterior spinal operation is treatment spinal trauma, the operative approach that disease is the most frequently used, most mature.In most cases need
The implantation of the internal fixation device of spine such as pedicle screw, pitman is carried out to fix centrum and play stable, support spinal motion segment
Effect.Since pedicle screw entry point is most often selected in the intersection point at transverse process midpoint Yu processus articular superior outer rim.Therefore need in art by
Exposure processus articular superior outer rim or even transverse process root, anatomically rich blood vessel herein, when exposure, often result in angiorrhoxis exacerbation
Intraoperative blood loss, and chest the small of the back spinous process two sides muscle is powerful, and Chang Xuchang time-histories retracts in order to the preparation of pedicle of vertebral arch screw nail channel
And implantation.After the completion of all technical operations such as nerve decompression, filling bone grafting, two sides are both needed to merging pitman for ipsilateral vertebral arch
Root screw is linked together, and is then screwed into tail cap and carrying out tail cap locking with the use of antitorque torque wrench makes interior fixed Combination at one
It is whole.
But found in actual operation, currently used transverse process point drag hook is usually integrated flat structure, handle with
How rectangular front is.Need to continue to retract backward strength in art, and every hand can only hold one.When carrying out, multi-segmental is more
It is unable to fully effectively retract muscle when the operations such as piece pedicle screw merging, and personnel's muscular fatigue hardly possible of responsible drag hook easily occurs
Situations such as with the maintenance of long time-histories.And front end flat design prepares pedicle channel and sets nail when that need to reserve certain leaning angle
When, the excessive risk increase that will lead to processus articular superior and iatrogenic fracture occurs of drag hook front end stress.In addition it is locked after tail cap is installed
Timing need to use antitorque torque wrench to prevent screw from swinging and cut to bone tissue, but to need supernumerary's merging antitorque habitually in the past
Torque wrench is tightened one by one, or even limited to be replaced with antitorque torque wrench by the drag hook in hand by drag hook personnel often auxiliary in surgical staff
Completion is helped to operate, it is time-consuming and laborious.
Summary of the invention
In view of the above-mentioned problems of the prior art, the utility model provides drag hook between a kind of assembly type multipurpose transverse process,
It is intended to overcome prior art defect, transverse process root can be anchored to by providing in a kind of operation of Thoracolumbar disk, can be facilitated operation, be saved people
Power, physical strength, and can sufficiently be satisfied with and appear the visual field, simplify surgical procedures, reduce operation risk, functions simultaneously as and be commonly used in art
Muscle pull device and antitorque torque wrench multipurpose transverse process between drag hook.
To achieve the goals above, the technical solution adopted in the utility model is: drawing between a kind of assembly type multipurpose transverse process
Hook, handle, drag hook blade and 2/3 circular arc molded cannula including having handle circular hole；The handle circular hole is opened in the end of handle
End；The drag hook blade is fixedly connected with handle；The bottom front of the drag hook blade is equipped with groove；2/3 circle
Camber casing both side edges are respectively provided with a pressure bar slot；90 degree are at right angles routed up outward and forms drag hook in the two sides of the drag hook blade
Semicircular arc card slot；The two sides of the 2/3 circular arc molded cannula at right angles inwardly rout up 90 degree and form semicircular arc-shaped casing card slot,
The drag hook blade outboard two edges are outside one's consideration to turn in 90 is formed by the arc-shaped card slot of drag hook, with 2/3 circular arc molded cannula two sides
The semicircular arc-shaped casing card slot for inwardly routing up 90 degree of formation matches to form a closed circular tubular.
Preferably, the handle and drag hook blade are in 150 degree of angles；Handle is in flat design；The drag hook blade
In to 1/3 circular-arc-shaped design of cardioid, end groove is arc-shaped；The handle is integrated with drag hook blade and sets
Meter.
Preferably, the 2/3 circular arc molded cannula both side edges are equipped with pressure bar slot, and pressure bar slot is axially perpendicular to 2/3 circular arc type
The central axis of casing.
Preferably, the handle, drag hook blade and 2/3 circular arc molded cannula are all made of dumb light titanium alloy material.
Preferably, the bottom plane of the 2/3 circular arc molded cannula is higher than the bottom plane 2-3cm of drag hook blade.
The beneficial effects of the utility model are: the utility model patent is using 150 degree of designs, it is used to be pressed downward
Strength can once hold more by stretching out forearm, wrist, hand completely, and in most cases by self gravity again slightly
Reinforcing amount reduces drag hook sliding, places the adverse effect less than position influence procedure.And when pitman merging, lead to
It crosses and tool is combined into twisting resistance spanner, space can be squeezed to avoid because being placed in common antitorque torque wrench, muscle is caused excessively to lead
Having pulled the excessive stress of muscle long-time ischemic necrosis or drag hook front end causes processus articular superior that iatrogenic fracture occurs.Simultaneously
It avoids simplifying operating procedure to reduce drag hook between the above risk taking-up transverse process and being placed in the redundant actions such as common antitorque torque wrench again.
