This kind of femur head necrosis pulp cavity pressure reducer through with in the pulp cavity drilling rod telescope sleeve pipe, in the rotating clamping groove on the locking cylinder precession cover cap, can not skid when drilling, can be more convenient throw the tissue into in, the sleeve pipe stay be convenient for inject therapeutic in driling to confirm the punch -position degree of depth in when film making through the scanning sleeve pipe, the secondary of the being convenient for location of punching, convenient to use.
Description
Technical field
This utility model relates to a kind of pressure reducer device, is specifically related to a kind of femur head necrosis medullary cavity decompression device, belongs to medical apparatus technical field。
Background technology
Clinical medicine needs to use a kind of medullary cavity decompression device in treatment femur head necrosis, prior art device only one of which rod, the drill bit of cruciate flower, throw easy frictional heat in bone into, and just take out after having beaten an eye, later stage medicine-feeding also to reopen, and cumbersome, and how deep the hole before cannot scanning when making film beaten, where, inconvenience secondary punching location, existing rod rear end of boring is that cylinder is easily skidded when using electric drill match-drill, and inconvenience uses。
For solving the problems referred to above, therefore it is proposed that a kind of femur head necrosis medullary cavity decompression device。
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, it is provided that a kind of femur head necrosis medullary cavity decompression device。
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model one femur head necrosis medullary cavity decompression device, including pulp cavity drilling rod and sleeve pipe, described pulp cavity drilling rod is cylindrical rod-like structure, described sleeve pipe is cylindrical tubular structure, described pulp cavity drilling rod bottom monoblock type is provided with Rhizoma Sparganii drill bit, described pulp cavity drilling rod upper end monoblock type is provided with triangular prism, described pulp cavity drilling rod is upper is arranged with locking column below triangular prism, described sleeve upper end integration is provided with the cap bag of hierarchic structure, described cap bag upper surface is arranged with rotation draw-in groove, described cap bag is identical with casing inner diameter through, and described casing shoe is ramp structure。
Further, described pulp cavity drilling rod external diameter less than casing inner diameter, described casing wall thickness 0.15mm。
Further, described casing inner diameter 4mm。
Further, described sleeve pipe total length 94mm。
Further, described cap bag height 5mm。
This utility model reaches to provide the benefit that: by packing in sleeve pipe by pulp cavity drilling rod, in rotation draw-in groove on locking column precession cap bag, the triangular prism of pulp cavity drilling rod upper end and electric drill secure fit, will not skid when boring, drill bit is arranged to Rhizoma Sparganii drill bit, can throw in tissue more easily, generation heat is little, after boring terminates, pulp cavity drilling rod is extracted with rotating exact separation by locking column, sleeve pipe is stayed in being holed and is easy to injection therapeutic medicine, injectable drug injected gel again after completing, prevent medicine from flowing out, and determine the punch position degree of depth when film making by scanning cannula, it is easy to secondary punching location, casing shoe ramp structure, it is easy in inserting hole, easy to use。
