Abstract
The utility model relates to an easy hollow pressurization spongiosa nail of modus ponens, including the polished rod section that is located anterior screw thread section with be located the rear portion, the screw thread section is including cylindric screw thread section that is located the anterior segment and the taper screw thread section that is located the back end, the diameter of taper screw thread section diminishes in the past backward gradually. When taking out hollow pressurization spongiosa nail, to move back during hollow pressurization spongiosa nail when locating to the cortex bone, taper screw section has direction and cutting action, and it is easier to take out.
Description
Technical field
This utility model relates to the nail that a kind of medical treatment orthopaedics uses, specifically a kind of easy taking type hollow pressurization spongiosa nail.
Background technology
At present, the Internal Fixation of fracture of femoral neck generally uses 3 hollow pressurization spongiosa nails to fix, and it has simple to operate, the little and fixing advantage such as reliable of wound.Operation is needed to take out hollow pressurization spongiosa nail after union of fracture.
Existing hollow pressurization spongiosa nail includes the light bar segment being positioned at rear portion and is positioned at the thread segment of front portion, and when installing hollow pressurization spongiosa nail, the spongy bone that screw thread cuts out femoral head is the easiest.Owing to the bone of people can grow, taking out hollow pressurization spongiosa nail, when screw thread retreats to the cortical bone at femur rear portion, hard cortical bone often results in screw thread to be difficult to cut out, thus " original place skidding ".Running into this situation clinically often needs 2 kinds of methods to solve: 1 expands nail road makes screw thread screw out, and this can cause the destruction of part sclerotin；2 give the bigger power outwards extracted when outwards screwing out screw, so that screw thread incision cortical bone, this method wastes time and energy, and screw with extract metal filings easy contaminated operation wound produced by the friction of apparatus.
Summary of the invention
Technical problem to be solved in the utility model is to provide the easy taking type hollow pressurization spongiosa nail of a kind of easy taking-up.
Easy taking type of the present utility model hollow pressurization spongiosa nail, including being positioned at the thread segment of front portion and being positioned at the light bar segment at rear portion；Described thread segment includes being positioned at the cylindrical screw section of leading portion and being positioned at the taper thread segment of back segment, and the diameter of described taper thread segment tapers into from front to back.
The length being shorter in length than cylindrical screw section of described taper thread segment.
The utility model has the advantage of: when taking out hollow pressurization spongiosa nail, when retreating at cortical bone during hollow pressurization spongiosa nail, taper thread segment has guiding and dissection, and taking-up is easier.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art hollow pressurization spongiosa nail；
Fig. 2 is the structural representation of easy taking type of the present utility model hollow pressurization spongiosa nail；
Fig. 3 is the use view of easy taking type of the present utility model hollow pressurization spongiosa nail.
Detailed description of the invention
As shown in fig. 2: a kind of easy taking type hollow pressurization spongiosa nail, including being positioned at the thread segment 02 of front portion and being positioned at the light bar segment 01 at rear portion；Described thread segment 02 includes the cylindrical screw section 021 being positioned at leading portion and is positioned at the taper thread segment 022 of back segment, and the diameter of described taper thread segment 022 tapers into from front to back.The length being shorter in length than cylindrical screw section 021 of described taper thread segment 022.The rear end of described smooth bar segment 01 has the head of a nail 03.
As it is shown on figure 3, after An Zhuaning, thread segment 02 is positioned in the screwed hole of spongy bone G of femoral head, light bar segment 01 is positioned in the unthreaded hole of hard cortical bone H.
