Abstract
The invention discloses a bridge type connector outside periosteum, which belongs to the field of medical instruments and consists of a steel fixing plate 1, fixing screws 2 and plate locking screws 3. The bridge type connector outside the periosteum is characterized in that a plurality of countersunk screw holes 4 are arranged on the steel fixing plate 1, plate locking screw holes 5 corresponding to the countersunk screw holes 4 respectively are arranged on the side opposite to the countersunk screw holes 4; each of the fixing screws consists of a circular screw head 6 and a screw rod 7, a plate locking screw rod hole 8 is arranged at the center of the screw head 6, an internal thread 9 is arranged on the inner side wall of the plate locking screw rod hole 8, and an external thread A10 is arranged on the screw rod 7; each of plate locking plates 3 consists of a plate locking screw head 1 and a plate locking screw rod 12, a cross slot 13 which is recessed is arranged on the plate locking screw head 11, and an external thread B14 is arranged on the plate locking screw rod 12. The bridge type connector outside the periosteum is simple in structure and convenient in use. During operation, the periosteum is not required to be stripped or less periosteum is required to be stripped, the fracture ends can be fixed by the steel fixing plate located outside the periosteum, and accordingly the bridge type connector has the advantages of causing small wounds to bones and increasing healing speed of fracture.
Description
Technical field: the invention belongs to medical instruments field, concretely, relate to a kind of in fracture open reduction internal fixation; Can not peel off or peel off less periosteum; Place periosteum can reach the fixedly purpose of fracture end outward fixation steel plate, damage for a short time, healing is fast; Simple in structure, the outer bridge-type bone fracture device of periosteum easy to use.
Background technology: in the orthopaedics clinical practice, fracture open reduction internal fixation is a basic operation technique.At present, clinical internal fixation mode commonly used is mostly for steel plate adds the multiple screws method, and this method need be peeled off the large tracts of land periosteum, and fixation steel plate is close on the fracture end surface; Tighten with screw then,, caused bigger wound to fracture end owing in this process, peeled off the large tracts of land periosteum; Influenced the hemotrophic nutrition supply of fracture end, postponed union of fracture, wasted time and energy; Bring bigger misery to the patient, also increased operating difficulty, increased medical worker's working strength.
Summary of the invention: the object of the present invention is to provide and a kind ofly in fracture open reduction internal fixation, can not peel off or peel off less periosteum, place periosteum can reach the fixedly purpose of fracture end outward fixation steel plate; Damage little; Healing is fast, and is simple in structure, the outer bridge-type bone fracture device of periosteum easy to use.
For realizing above-mentioned purpose, the present invention has taked following technical scheme: the outer bridge-type bone fracture device of this periosteum is made up of fixation steel plate, hold-down screw and jam plate nail; Fixation steel plate is provided with several countersunk head screws, and the offside of each countersunk head screw is respectively equipped with corresponding with it jam plate nail hole, and hold-down screw is made up of rounded head and nail bar; The central authorities of ailhead are provided with jam plate nail bar hole; The medial wall in jam plate nail bar hole is provided with female thread, and the nail bar is provided with external screw thread A, and the jam plate nail is made up of jam plate ailhead and jam plate nail bar; The cross draw-in groove that does not have depression on the jam plate ailhead, jam plate nail bar is provided with external screw thread B.
The present invention, simple in structure, easy to use, in operation, can not peel off or peel off less periosteum, place periosteum can reach the fixedly purpose of fracture end outward fixation steel plate, have the damage little, fast advantage heals.
Description of drawings: the present invention is described further below in conjunction with accompanying drawing.
Fig. 1 is an overall structure sketch map of the present invention.
Fig. 2 is the structural representation of fixation steel plate among the present invention.
Fig. 3 is the structural representation of hold-down screw among the present invention.
Fig. 4 is the structural representation of jam plate nail among the present invention.
With reference to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 and accompanying drawing 4,1, fixation steel plate, 2, hold-down screw; 3, jam plate nail, 4, the countersunk head screw, 5, jam plate nail hole, 6, ailhead; 7, nail bar, 8, jam plate nail bar hole, 9, female thread, 10, external screw thread A; 11, jam plate ailhead, 12, jam plate nail bar, 13, the cross draw-in groove, 14, external screw thread B.
The specific embodiment: the present invention, constitute by fixation steel plate 1, hold-down screw 2 and jam plate nail 3, fixation steel plate 1 is provided with several countersunk head screws 4; The offside of each countersunk head screw 4 is respectively equipped with corresponding with it jam plate nail hole 5; Hold-down screw 2 is made up of rounded head 6 and nail bar 7, and the central authorities of ailhead 6 are provided with jam plate nail bar hole 8, and the medial wall in jam plate nail bar hole 8 is provided with female thread 9; Nail bar 7 is provided with external screw thread A10; Jam plate nail 3 is made up of jam plate ailhead 11 and jam plate nail bar 12, does not have the cross draw-in groove 13 of depression on the jam plate ailhead 11, and jam plate nail bar 12 is provided with external screw thread B14.
Use when of the present invention; Nail bar 7 with hold-down screw 2 inserts two fracture ends respectively earlier; It is fixed, then the countersunk head screw 4 on the fixation steel plate 1 is set to respectively on the ailhead 6 of hold-down screw 2, reuse jam plate nail 3 passes in the jam plate nail bar hole 8 on the jam plate nail hole 5 precession hold-down screws 2 on the fixation steel plate 1; Fixation steel plate 1 is kept somewhere gap or subcutaneous arbitrary gap under extraperiosteal spatium intermusculare, fascia, press routine operation suture operation otch at last and get final product.
