Abstract
The utility model provides a biotype locking steel plate for a pelvic posterior ring, which belongs to the technical field of medical instruments. The locking steel plate structurally comprises a steel plate and bone nails, wherein the steel plate is in the shape of M; two M-shaped peaks are positioned at the two ends of the steel plate respectively; the center of the steel plate is in the shape of a straight plate; more than one nail hole is formed on each of the two peaks of the steel plate; biodegradable universal locking thread cover nuts are arranged on the inner edges of the nail holes respectively; threads matched with fine threads of the nail tails of the bone nails are formed on the inner edges of the biodegradable universal locking thread cover nuts; self-tapping threads are formed on the nail bodies of the bone nails; and the nail bodies of the bone nails pass through the biodegradable universal locking thread cover nuts in the nail holes, and then tails of the nails are in threaded connection with the biodegradable universal locking thread cover nuts. The biotype locking steel plate can solves the problem in the traditional steel plate that steel plate screws are broken due to unstable fixation in early stage and stress concentration in late stage, and has the advantages of convenience, practicability, short operation time and good clinical effect.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of posterior ring pelvic biotype locking steel plate.
Background technology
General, joint comminuted fracture, breaking type fracture, it is more common fracture phenomenon, if displacement obviously, should resolutely adopt operative treatment, operation plan is fixing best with open reduction, near-end locking steel plate, though the locking steel plate price is high, but because the old people has degrees of osteoporotic, so locking steel plate has special advantage for the old people.But the steel plate fixture under the prior art is too hard, for some skeletons, when the normal joint motion of human body, need the cooperation of the toughness bending of skeleton itself, yet at this point, just there is defective to a certain extent in some skeleton steel plate fixed solution.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of posterior ring pelvic biotype locking steel plate is provided.
The technical solution of the utility model realizes in the following manner, this posterior ring pelvic biotype locking steel plate, its structure comprises steel plate and nail, steel plate is " M " type, two peaks of " M " type lay respectively at the two ends of steel plate, it is directly tabular that steel plate central authorities are, offer the nail hole of an above quantity on two peaks of steel plate respectively, each is followed closely the hole inner edge and is respectively arranged with Biodegradable universal lock screw thread cap bag, this Biodegradable universal lock screw thread cap bag inner edge offers the screw thread that matches with nail nail tail fine thread, nail nail body is provided with self-tapping screw, and the nail tail was connected with Biodegradable universal lock thread bush cap thread after the nail body of nail passed the Biodegradable universal lock screw thread cap bag of following closely in the hole.
Offer respectively on two peaks of steel plate and be equipped with five nail holes, the axially staggered of five nail holes is not parallel to each other.
Nail nail tail tail end diameter is greater than the diameter in nail hole on the steel plate.
Biodegradable universal lock screw thread cap bag is a supra polymer polylactic acid Biodegradable universal lock screw thread cap bag.
The beneficial effect that this utility model is compared with prior art produced is:
This posterior ring pelvic biotype locking steel plate is a kind of medical locking steel plate, be designed to the M type according to ring anatomical shape behind the human pelvis, by cap bag structural design between nail nail tail and steel plate hole, locking fully between fixing early stage nail and steel plate, after the posterior ring pelvic healing, the cap bag degraded can be movable between nail and the steel plate, thereby allow posterior ring pelvic as amphiarthrodial physiological activity.Be embodied in: this posterior ring pelvic biotype locking steel plate design Biodegradable universal lock screw thread cap bag adopts absorbable supra polymer polylactic acid to be designed to two-sided universal lock, and 30 degree movable corner are arranged.Lock the 3-4 month after screwing fully, after the posterior ring pelvic healing, the cap bag degraded can be movable between screw and the steel plate, the steel plate screw breakage problem of having avoided posterior ring pelvic to produce as an amphiarthrosis extended immobilization.
The characteristics design of this posterior ring pelvic biotype locking steel plate, can improve conventional steel plates stress concentration in early days fixing not firm and late period and cause the steel plate screw breakage problem, simple in structure, convenient and practical, operating time is short, clinical effectiveness good, has good promotion prospect.
Description of drawings
Accompanying drawing 1 is a perspective view of the present utility model;
Accompanying drawing 2 is the syndeton sketch maps between nail of the present utility model and the steel plate.
Labelling in the accompanying drawing is represented respectively:
1, steel plate, 2, nail, 3, the nail hole, 4, Biodegradable universal lock screw thread cap bag, 5, the nail tail, 6, nail tail fine thread, 7, the nail body, 8, self-tapping screw.
The specific embodiment
Below in conjunction with accompanying drawing posterior ring pelvic biotype locking steel plate of the present utility model is done following detailed description the in detail.
Shown in accompanying drawing 1,2, posterior ring pelvic biotype locking steel plate of the present utility model, its structure comprises steel plate 1 and nail 2, steel plate 1 is " M " type, two peaks of " M " type lay respectively at the two ends of steel plate 1, offer respectively on two peaks of steel plate 1 and be equipped with five nail holes, the axially staggered of five nail holes is not parallel to each other.Steel plate 1 central authorities are directly tabular, each is followed closely the hole inner edge and is respectively arranged with supra polymer polylactic acid Biodegradable universal lock screw thread cap bag 4, these Biodegradable universal lock screw thread cap bag 4 inner edges offer the screw thread that matches with nail nail tail fine thread 6, nail nail body 7 is provided with self-tapping screw 8, and the Biodegradable universal lock screw thread cap bag 4 back nail tails 5 that the nail body 7 of nail passes in the nail hole 3 are threaded with Biodegradable universal lock screw thread cap bag 4.Nail nail tail 5 tail end diameters are greater than the diameter in nail hole 3 on the steel plate.
This posterior ring pelvic biotype locking steel plate is designed to the M type according to the posterior ring pelvic anatomical shape, and steel plate is placed near the posterior superior iliac spine at ala sacralis rear, and clothes are pasted better in steel plate and pelvis rear portion.The bone screw holes at steel plate two ends is the multi-direction bilateral ala of ilium rear of being fixed in.Biodegradable universal lock screw thread cap bag 4 adopts absorbable supra polymer polylactic acid to be designed to two-sided locking screw thread cap bag, locking fully after screwing, after the degraded, can be movable between screw and the steel plate, avoided problems such as steel plate screw fracture that sacroiliac joint after the union of fracture produces because of extended immobilization as an amphiarthrosis and pain.
