Abstract
The utility model relates to a novel self-locking intramedullary needle, which belongs to the field of medical appliances. The novel self-locking intramedullary needle consists of a needle point 1, a needle rod 2, a needle core 3, a needle handle 4, a sealing cap 5, a self-locking plate 6 and self-locking nails 7, and is characterized in that the top end of the needle point 1 is a blind end; the side face of the needle point 1 is provided with a side hole 8; the head part of the needle core 3 extends obliquely out of the side hole 8; the side face of the needle rod 2 is provided with a plurality of self-locking holes 9; the self-locking holes 9 correspond to the self-locking nails 7 on the self-locking plate 6; and the needle handle 4 is provided with the sealing cap 5. The novel self-locking intramedullary needle is simple in structure, is convenient to use, is particularly suitable for fracture reduction internal fixation for osteoporotic patients, and is an ideal self-locking intramedullary needle; and stresses such as rotation, twisting, separation and the like at a fracture end can be effectively controlled.
Description
Technical field:
This utility model belongs to medical instruments field, and particularly a kind of rotation, twist and warping, the separation iso-stress that can effectively control fracture end is applicable to the reduction of the fracture internal fixation of sufferers of osteoporosis face, novel self-locking intramedullary needle simple in structure, easy to use.
Background technology:
To add internal fixation be the clinical a kind of modus operandi commonly used of orthopaedics to the fracture open reduction, is used for the fracture patient treatment that undergos surgery is resetted two fracture ends, adopts internal fixation apparatus that fracture end is reinforced then, is shifted to avoid fracture end.In the orthopaedics clinical practice, often run into some sufferers of osteoporosis face, implementing in the internal fixation process for it; Loose sclerotin usually interlock does not live internal fixation apparatus, causes operative failure, and perhaps postoperative produces the fracture end displacement; Need operative treatment again; Increase bigger loss and misery to the patient, also increased medical worker's workload, thereby caused very big medical resource waste.
Summary of the invention:
The purpose of this utility model is to provide a kind of rotation, twist and warping, the separation iso-stress that can effectively control fracture end, is specially adapted to the reduction of the fracture internal fixation of sufferers of osteoporosis face, novel self-locking intramedullary needle simple in structure, easy to use.
For realizing above-mentioned purpose, this utility model has been taked following technical scheme: this novel self-locking intramedullary needle is made up of needle point, shank, nook closing member, needle handle, sealing cap, self-locking plate and self-locking nail; The top of needle point is a cecum, and the side of needle point is provided with side opening, and the head of nook closing member can pass through the outside diagonal of side opening; Be used for effectively controlling rotation, twist and warping, the separation iso-stress of fracture end; The side of shank is provided with several self-locking holes, and self-locking hole is corresponding each other with self-locking nail on the self-locking plate, is used for strengthening the self-locking constant intensity between nook closing member and the self-locking plate; Needle handle is provided with sealing cap, is used for strengthening being connected between needle handle and the nook closing member.
This utility model, simple in structure, easy to use, can effectively control rotation, twist and warping, the separation iso-stress of fracture end, be specially adapted to the reduction of the fracture internal fixation of sufferers of osteoporosis face, be a kind of ideal novel self-locking intramedullary needle.
Description of drawings:
Below in conjunction with accompanying drawing this utility model is described further.
Fig. 1 is the structural representation of this utility model.
With reference to accompanying drawing 1,1, needle point, 2, shank, 3, nook closing member, 4, needle handle, 5, sealing cap, 6, self-locking plate, 7, self-locking nail, 8, side opening, 9, self-locking hole.
The specific embodiment:
This utility model; Be made up of needle point 1, shank 2, nook closing member 3, needle handle 4, sealing cap 5, self-locking plate 6 and self-locking nail 7, the top of needle point 1 is a cecum, and the side of needle point 1 is provided with side opening 8; The head of nook closing member 3 passes through side opening 8 outside diagonals; The side of shank 2 is provided with several self-locking holes 9, and the self-locking nail 7 on self-locking hole 9 and the self-locking plate 6 is corresponding each other, and needle handle 4 is provided with sealing cap 5.
When using this utility model, earlier shank 2 is passed two fracture ends, after two fracture end para-positions neatly; Nook closing member 3 is inserted in the shank 2; Head until nook closing member 3 passes through side opening 8 outside diagonals, then sealing cap 5 is screwed on needle handle 4, makes shank 2, nook closing member 3 and sealing cap 4 in aggregates; Reuse self-locking nail 7 inserts in the self-locking hole 9 to be screwed, and self-locking plate 6 is fixed in fracture end gets final product.
