Description
Technical field
This utility model relates to a kind of pedicle for cervical vertebra arch passage-opening awl, the neck of a kind of band abduction angle measuring device
Vertebra pediculus arcus vertebrae opening is bored.
Background technology
At present, when cervical spine injury patient being carried out posterior Pedicle nail-stick system and fixing, pedicle nail is first carried out
Implanting, owing to cervical incision is relatively deep, muscular tissue is thicker, and the abduction angle of passage-opening awl is by range estimation, and precision is low, passage-opening awl
Entering to follow closely direction and be difficult to be grasped by operator because of the stop of muscular tissue, the outer wall in prefabricated nail road is easily punctured, cause hemorrhage or
Bigger accident surgery, wastes time and energy during operation, and vertebral artery injuries risk is high.
Utility model content
This utility model is for the technological deficiency mentioned in background technology, it is provided that a kind of simple in construction, easy to operate, essence
The pedicle for cervical vertebra arch passage-opening awl of the band abduction angle measuring device that accuracy is high.
The technical solution adopted in the utility model is: the pedicle for cervical vertebra arch passage-opening awl of a kind of band abduction angle measuring device, bag
Include the conehead of passage-opening awl, taper shank and handle, it is characterised in that also include angle measurement equipment；
Described conehead is placed in taper shank front end, is structure as a whole with taper shank, and conehead is the blunt flat inclined flat structure in tip；
Described taper shank is crank, and crank is semi-circular arc structure；Taper shank tail end is fixing to be inserted in handle；
Described handle side arranges a shank；Described angle measurement equipment is disc-shaped structure, and angle measurement equipment central authorities are arranged
Having mesopore, this mesopore matches with shank；It is connected with one below described angle measuring scale excircle to hang down handle.
On handle outer surface, its axis being provided with a datum line, this datum line crosses shank center.
It is provided with angle index on angle measurement equipment front surface, is marked with scale 0 °-90 °-0 °-90 ° along its circumferencial direction,
Angle groove it is provided with between adjacent scale.
Vertical handle and 0 ° of-0 ° of graduation mark are vertically arranged.
For being flexibly connected form between angle measurement equipment with shank.
The central axis of conehead and the central axis of handle are positioned on same level line.
This passage-opening awl disclosed in the utility model, simple in construction, easy to operate, precision is high, improves successful surgery
Rate, reduces operation risk, time saving and energy saving, safe and reliable.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is angle measurement equipment structural representation.
In figure: conehead 1, taper shank 2, handle 3, angle measurement equipment 4, shank 5, hang down handle 6, datum line 7.
Detailed description of the invention
With embodiment, this utility model is described further below in conjunction with the accompanying drawings.
Seeing accompanying drawing 1-2, in the present embodiment, this passage-opening awl includes conehead 1, taper shank 2, handle 3, angle measurement equipment 4, pin
Body 5, hang down handle 6, datum line 7.
The pedicle for cervical vertebra arch passage-opening awl of this band abduction angle measuring device, including passage-opening awl body and angle measurement equipment, its
In, passage-opening awl body includes conehead, taper shank and handle.
Conehead is placed in taper shank front end, is structure as a whole with taper shank, and conehead is flat shape, and it is the blunt flat inclined reef knot in tip
Structure, tip is blunt flat, is beneficial to advance in pedicle of vertebral arch pipe spongy bone, it is possible to be prevented effectively from conehead and puncture tube wall.
Taper shank is crank, and as preferably, crank is semicircular arc structure, is beneficial to avoid the stop of side soft tissue.
Taper shank tail end is fixing to be inserted in handle, and handle generally uses wooden handle.Handle side arranges a shank, preferably installs
On the side of oriented manipulation person.This shank protrudes on handle slightly, for suspension angles measuring device.
Angle measurement equipment is disc-shaped structure, and angle measurement equipment central authorities are provided with mesopore, and this mesopore matches with shank, just
In the suspension of angle measurement equipment with win.It is connected with one below angle measuring scale excircle to hang down handle.
On handle outer surface, its axis being provided with a datum line, this datum line crosses shank center.The central axis of conehead
It is positioned on same level line with the central axis of handle.
It is provided with angle index on angle measurement equipment front surface, is marked with scale 0 ° 90 0 ° along its circumferencial direction
90 ° of four scales, lay respectively at 0 ° of circumference, 90 °, 180 °, the position of 270 °, are provided with angle groove between adjacent scale,
The interval number of degrees of graduation mark are not less than 5 °.
Vertical handle and 0 ° of-0 ° of graduation mark are vertically arranged, and the handle that i.e. hangs down remains vertical state.In angle measurement equipment, angle is corresponding
Angle between line and the datum line of handle, is the required angle of splay of operation.
Preferably, a diameter of 2.5mm of angle measurement equipment hollow, and the external diameter of shank is 2mm, therebetween can
Enough freely win.
Using method of the present utility model is as follows:
The abduction angle of the pedicle of vertebral arch according to preoperative measurement, adjusts the abduction angle of crank cone so that it is conehead front end props up
Bore position, by turning handle, makes on handle in datum line and angle measurement equipment the angle between horizontal scale line be combined
Required abduction angle, when two angles are consistent on dekkor, takes off angle measurement equipment, according to this angle is just being bored by crank
Anti-half-turn rotates propelling, gradually precession pedicle of vertebral arch repeatedly, elicites nail road four wall with fine probe and bottom is complete after taking out passage-opening awl
Without run-down, it is screwed into suitable length pedicle nail.Taper shank is semicircular structure, can avoid the pushing away of muscular tissue of side
Gear, and taper shank is positive and negative half-turn repeatedly rotates propelling, and this open circuit device is on the direction of the angle according to preoperative measurement, does not has
Have in the case of the external force of any side gradually in advancing in pedicle of vertebral arch pipe.
