Abstract
The utility model discloses a medical screw comprises cylindrical guiding, a first bone connection screw, a first cylinder, a clamping plane, a second cylinder and a second bone connection screw. The cylindrical guiding, the first bone connection screw, the first cylinder, the clamping plane, the second cylinder and the second bone connection screw are orderly connected; and the a taper of the cylinder guiding and a taper of the second bone connection screw are both a sealing surface. The beneficial effects of the medical screw are that two end tapers are sealing surfaces; the surface of the medical screw is polished, sandblasted and electrolyzed, so the surface of the medical screw is smooth and clean, free of sharp edged rags and free of microcracks; heat treating hardness is HRC 40 to 44; and a bone connection direction can be freely chosen, thereby providing the medical screw with wide application range.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of Medical screw.
Background technology
In hospital orthopedics, fracture patient is modal, conventionally be exactly to adopt trip bolt to carry out interior fixing to fracture patient, trip bolt is skeletal fixation device conventional in bone surgery, the trip bolt using at present comprises that rivet nut and the head of a nail form, the head of a nail and rivet nut are welded and fixed and are integrated, in rivet nut, be provided with screw thread, the deficiency that this trip bolt exists is, in long-term interior fixing, easily in osseous tissue, produce loosening, be not easy and osseous tissue strong bonded, fracture face is thrown off or dislocation, cause synthetism failure, if there is this kind of situation, need again to tidy up reset, bring larger misery to patient, on nut due to existing tibia screw, become yi word pattern groove in addition, be screwed in the process in bone hole at trip bolt, the stress surface of trip bolt is on nut, be screwed into the instrument of screw with easily slippage from yi word pattern groove, make troubles to operation.Existing Medical screw is all unidirectional simultaneously, and the scope of application is little.
Utility model content
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of Medical screw, can freely select as required the direction of synthetism, applied widely.
A kind of Medical screw, comprise cylinder guiding, the first bone connecting screw, the first cylinder, clamping plane, the second cylinder and the second bone connecting screw, described cylinder guiding, the first bone connecting screw, the first cylinder, clamping plane, the second cylinder are connected successively with the second bone connecting screw, and described cylinder guiding is sealing surface with the tapering of described the second bone connecting screw.
As preferably, described the first cylindrical length is 74.7mm.
As preferably, described the second cylindrical length is 0.5 mm.
As preferably, the diameter of described the second bone connecting screw is 5.2mm.
The beneficial effects of the utility model: this utility model two ends tapering is sealing surface, surface is through polishing, sandblast, electrolytic treatments, and appearance is bright and clean, without cutting edge of a knife or a sword rib burr, non-microcracked, and heat treatment hardness is HRC40～44, can freely select as required the direction of synthetism, applied widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that this utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth this utility model.
With reference to Fig. 1, this specific embodiment is by the following technical solutions: a kind of Medical screw, comprise cylinder guiding 1, the first bone connecting screw 2, the first cylinder 3, clamping plane 4, the second cylinder 5 and the second bone connecting screw 6, described cylinder guiding 1, the first bone connecting screw 2, the first cylinder 3, clamping plane 4, the second cylinder 5 is connected successively with the second bone connecting screw 6, described cylinder guiding 1 is sealing surface with the tapering of described the second bone connecting screw 6, described cylinder guiding 1, the first bone connecting screw 2, the first cylinder 3, clamping plane 4, polishing is all passed through on the second cylinder 5 and the second bone connecting screw 6 surfaces, sandblast and electrolytic treatments.
Length that it should be noted that described the first cylinder 3 is 74.7mm.
Length that it should be noted that described the second cylinder 5 is 0.5 mm.
In addition, the diameter of described the second bone connecting screw 6 is 5.2mm.
Wherein, making requirement of the present utility model is: 1, not noting chamfering is C0.2; 2, two ends tapering is sealing surface, notes its cone of management and control and fineness thereof; 3, appearance bright and clean, without cutting edge of a knife or a sword rib burr, the defect such as non-microcracked; 4, heat treatment hardness HRC40～44; 5, surface finish, sandblast, electrolytic surface processing.
This is concrete, and to implement two ends tapering be sealing surface, and surface is through polishing, sandblast, electrolytic treatments, and appearance is bright and clean, without cutting edge of a knife or a sword rib burr, non-microcracked, and heat treatment hardness is HRC40～44, can freely select as required the direction of synthetism, applied widely.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in this utility model patent claim therefore all changes or modifies, and is included in this utility model patent claim.
