Abstract
Take hollow hexagonal screw sword of scale relates to a medical instrument. Be equipped with and take scale empty core rod, sleeve and handle, the front end of taking the empty core rod of scale is equipped with the hexagonal cone, the sleeve embolias takes scale core rod's rear portion in vain, and the rear portion of taking the scale to empty core rod is passed through the sleeve and is connected with the handle. Take the empty core rod of scale to adopt and take scale hollow round bar, the hexagonal cone can adopt length to be 3~5mm's hollow hexagonal cone. Can reduce the perspective, only need once to have a X -rayed, reduce the damage of doctors and patients' ray and reduce operation time. Screw speed is twisted by within range between the cortex of skin to the thighbone outside can be very fast, unnecessaryly anxious twists dark, so can shorten operation time. Twist the degree of depth through the visual control spanner of naked eye, rather than relying on insecure controlling depth of feeling, can guarantee that the screw degree of depth is suitable, greatly increased patient's security.
Description
Technical field
This utility model is related to a kind of medical apparatus and instruments, especially relates to a kind of hollow hexagonal screwdriver with a scale.
Background technology
Fracture of femoral neck is not substantially shifted or the slight patient shifting, or moderate displacement fracture after resetting
The good young and middle-aged patient of para-position or old people, are ready to accept hollow lag screw fixation person, have using in open reduction in the past
Fixing or fixing in closed reduction percutaneous pinning.In closed reduction percutaneous pinning, to have, patient little to tissue injury extensive for fixation
Multiple fast the features such as, but original operational approach is:
1st, see that the reduction of the fracture is satisfied with c arm x line machine perspective；
2nd, pierce fixation with 3 pieces of kirschner guide pin, the position of kirschner guide pin is in triangle disposition as far as possible, perspective adjustment gram again
Family name's guide pin position is satisfied with to the depth of kirschner guide pin, direction；
3rd, entering at pin mark in kirschner guide pin, cuts skin about 1cm with sharp knife centered on kirschner guide pin, and along kirschner
Guide pin cuts a passage to femoral surface to the direction of femur；
4th, with depth finder measurement kirschner guide pin from lateral side of femur cortex to capital depth；
5th, holed to through lateral side of femur cortex with hollow boring bit；
6th, it is screwed into according to the kirschner guide pin depth of measurement and be screwed into the hollow of close length with inner hexagon spanner along kirschner guide pin
Lag screw, the process of being screwed into must be had an X-rayed repeatedly, prevents from being screwed into too deep, contacting to the head of a nail with lateral side of femur cortex；
7th, finally rinse otch, sew up the incision, terminate operation.
Existing operational approach there is problems in that
1st, during being screwed into hollow lag screw with inner hexagon spanner, if patient's sclerotin is harder, when the head of a nail and femur
During lateral cortex contact, patient can substantially feel to need larger power just can be screwed into, and at this moment shows that screw has put in place it is impossible to more
It is screwed into.When patient is elderly patients or other more loose person of reason sclerotin, when the head of a nail is contacted with lateral side of femur cortex, patient is still
When can easily be screwed into very much without obvious resistance shelves, then screw will continue to be screwed into, and lead to screw to enter articular cavity destruction joint soft
Bone face；Even screw enters pelvic cavity, causes massive hemorrhage even to cause death.This severe complication is many.
2nd, it is to avoid screw entrance too deep, only repeated multiple times perspective at present, the depth being entered by fluoroscopic monitoring screw
Degree, and this will increase the x line loss evil of medical personnel and patient, and increase operating time and patient risk.
Content of the invention
The purpose of this utility model is to provide a kind of improved hollow hexagonal screwdriver with a scale.
This utility model is provided with hollow stem with a scale, sleeve and handle；The front end of described hollow stem with a scale is provided with hexagonal
Cone, described sleeve is inserted in the rear portion of hollow stem with a scale, and the rear portion of hollow stem with a scale is connected with handle by sleeve.
Described hollow stem with a scale can adopt Hollow circular beam with a scale, and described hexagonal pyramid can be 3～5mm's using length
Hollow hexagonal pyramid.
The rear portion that described sleeve is inserted in hollow stem with a scale can be using being welded and fixed.
The rear portion of described hollow stem with a scale is connected with handle by sleeve and can adopt pin fastener.
Described handle can adopt hollow handle, and hollow part can pass through the Kirschner wire of a diameter of 3mm.
Compared with prior art, this utility model has the advantage that
1st, perspective can be reduced, only need to once have an X-rayed, reduce doctors and patients' RADI and reduce operating time.
2nd, being screwed into screw speed between skin to lateral side of femur cortex can be comparatively fast it is not necessary to worry to be screwed into
Deep, therefore can shorten operating time.
3rd, by macroscopic control spanner be screwed into depth, rather than carry out controlling depth with insecure feel it is ensured that
Screw depth is suitable, greatly increases the safety of patient.
Brief description
Fig. 1 is the structure composition schematic diagram of this utility model embodiment.
Fig. 2 is the structural decomposition diagram of this utility model embodiment.
Specific embodiment
Following examples will combine accompanying drawing and this utility model will be further described.
Referring to Fig. 1 and 2, this utility model embodiment is provided with hollow stem 1 with a scale, sleeve 2 and handle 3；Described with a scale
The front end of hollow stem 1 is provided with hexagonal pyramid 11, and described sleeve 2 is inserted in the rear portion of hollow stem 1 with a scale, hollow stem 1 with a scale
Rear portion is connected with handle 3 by sleeve 2.
Described hollow stem with a scale 1 can adopt Hollow circular beam with a scale, and described hexagonal pyramid 11 can be 4mm's using length
Hollow hexagonal pyramid.
The rear portion that described sleeve 2 is inserted in hollow stem 1 with a scale can be using being welded and fixed.
The rear portion of described hollow stem with a scale 1 is connected with handle 3 and can be fastened using pin 4 by sleeve 2.
Described handle 3 can adopt hollow handle, and hollow part can pass through the Kirschner wire of a diameter of 3mm.
Operational approach of the present utility model given below:
1st, see that the reduction of the fracture is satisfied with c arm x line machine perspective；
2nd, pierce fixation with 3 pieces of kirschner guide pin, the position of kirschner guide pin is in triangle disposition as far as possible, perspective adjustment gram again
Family name's guide pin position is satisfied with to the depth of kirschner guide pin, direction；
3rd, entering at pin mark in kirschner guide pin, cuts skin about 1cm with sharp knife centered on kirschner guide pin, and along kirschner
Guide pin cuts a passage to femoral surface to the direction of femur；
4th, measure kirschner guide pin from lateral side of femur cortex to capital depth with depth finder -- it is also that screw is selected
Length (such as 10cm)；Meanwhile, measure lateral side of femur cortex to the depth (such as 3cm) of skin；
5th, holed to through lateral side of femur cortex with hollow boring bit；
6th, it is screwed into the hollow lag screw of close length (such as 10cm) along kirschner guide pin with inner hexagon spanner with a scale,
Being threaded into the submerge depth of skin of inner hexagon spanner is exactly the lateral side of femur cortex that the records depth (such as 3cm) to skin, this
When with c arm x line machine perspective once confirm；
7th, finally rinse otch, sew up the incision, terminate operation.
