Abstract
A kind of medical multifunctional bit protector, including inner tube, outer tube, it is characterised in that there is lock hole, rectangular lock hole, inner tube graduated scale in said inner tube, there is locking window on the outer tube, lock window graduated scale；Said inner tube matches in outer tube and being capable of pull activity；The lock hole and the mating depth limiting pole of rectangular lock hole, depth limiting pole can flexibly be inserted in the lock hole and rectangular lock hole and be taken.It is drilling depth the beneficial effects of the invention are as follows the depth i.e. difference of scale value for entering outer tube according to drilling front and back inner tube, depth measurement is accurate and reliable, eliminates inconvenience and unreliability with dipstick measurement depth, saves operating time；Assistant can directly lock drilling depth to being reliably fixed for depth limiting pole, avoid and be pierced into excessive or too deep when drill bit drills through opposite side cortical bone, improve operation safety.
Description
Technical field
The present invention relates to a kind of Medical bit protective devices, more particularly, to a kind of dress of medical multifunctional drill bit protection
It sets.
Background technique
Currently, it is well known limbs fracture open reduction Plate internal fixiation operation in, it is necessary to electric drill drill on bone with
Drilling depth is measured, to select the steel nail of appropriate length to fix.Common drill bit protection cannot measure drilling in boring procedure
Depth measures the screw of selection corresponding length after drilling depth with dipstick after drilling.
Summary of the invention
Drilling depth cannot be measured in order to solve the common drill bit protection in boring procedure, uses depth measurement after drilling
Ruler measure drilling depth after select corresponding length screw deficiency, the present invention provide it is a kind of in order to improve drilling safety and
The inconvenience for saving dipstick depth measurement, the medical multifunctional bit protector designed and produced is in addition to that can protect around soft group
It knits, limit outside drilling depth, moreover it is possible to measure a kind of medical multifunctional bit protector of drilling depth.
The technical solution adopted by the present invention to solve the technical problems is a kind of medical multifunctional bit protector, including interior
Pipe, outer tube, it is characterised in that there is lock hole, rectangular lock hole, inner tube graduated scale in said inner tube, there is lock on the outer tube
Determine window, lock window graduated scale: said inner tube matches in outer tube and being capable of pull activity；The lock hole and rectangular lock
Determine the mating depth limiting pole in hole, depth limiting pole can flexibly be inserted in the lock hole and rectangular lock hole and be taken.
It is deep for drilling the beneficial effects of the invention are as follows the depth i.e. difference of scale value of outer tube is entered according to drilling front and back inner tube
Degree, depth measurement is accurate and reliable, inconvenience and unreliability with dipstick measurement depth is eliminated, when saving operation
Between；Assistant can directly lock drilling depth to being reliably fixed for depth limiting pole, avoid when drill bit drills through opposite side cortical bone and be pierced into
It is more or too deep, operation safety is improved, operation wound is reduced；It, can also basis other than being counted according to the graduated scale of inner tube
The longitudinal bore arranged side by side of inner tube counts, since longitudinal bore center of circle transverse direction line spacing is 1mm, count inner tube hole number arranged side by side from
Drilling starts to drilling to terminate to reduce number to be drilling depth millimeter, and when half of hole will count 1, interval of rectangular hole generation
It is 10 millimeters.Insufficient: the absolute reliability for limiting drilling depth will be reliably fixed depth limiting pole by assistant.Structure of the invention
Simply, easy to use, it is economical and practical.In 40 acropathy long bone fractures open reduction internals fixation with steel plate, boring procedure is uniform
Secondary completion, no an example generation drill bit piercing opposite side tissue is excessive or too deep, and C arm perspective is too long or too short without an example screw in art,
Good results.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is inner tube appearance diagram of the present invention.
Fig. 2 is outer tube appearance diagram of the present invention.
Fig. 3 is that schematic diagram is applied in combination in inner and outer tubes of the present invention.
Fig. 4 is depth limiting pole schematic diagram.
1. inner tube in figure, pipe cap in 2., 3. lock holes, 4. rectangular lock holes, 5. inner tube graduated scales, 6. scale integer marks
Point, 7. outer tubes, 8. locking windows, 9. locking window graduated scales, 10. outer tube caps, 11. tenon silk mouths, 12. depth limiting poles, 13. handles.
Specific embodiment
In the accompanying drawings, a kind of medical multifunctional bit protector, including inner tube 1, outer tube 7, it is characterised in that said inner tube 1
It is upper that there is lock hole 3, rectangular lock hole 4, inner tube graduated scale 5, there is locking window 8, locking window graduated scale on the outer tube 7
9；Said inner tube 1 matches in outer tube 7 and being capable of pull activity；The lock hole 3 and the mating depth limiting pole of rectangular lock hole 4
12, depth limiting pole 12 can flexibly be inserted in lock hole 3 and rectangular lock hole 4 and be taken.First the tenon silk mouth 11 of outer tube 7 is rotated when use solid
Due to operation position steel plate screw hole on, then will inner tube 1 be inserted into outer tube 7 in, allow drill bit arrive at steel plate side cortical bone, inner tube 1 push up
Closely electric drill head is held, 1 residue length of inner tube, the i.e. scale value of 7 top inner tube graduated scale 5 of outer tube is write down, starts to drill, drill through steel
Stop boring when plate side seam matter, by pulp cavity, drill bit is allowed to arrive at opposite side sclerotin, according to fracture opposite side sclerotin thickness, in locking window 8
Corresponding locking window graduated scale 9 is inserted into depth limiting pole 12 and is reliably fixed, and patient trusts that drilling causes depth limiting pole 12 and locking window 8
Following contact, then write down 1 residue length of inner tube, i.e., the scale value of 7 top inner tube graduated scale 5 of outer tube, drilling front and back inner tube 1 enter
Depth, that is, scale value difference of outer tube 7 is drilling depth.
