Abstract
The utility model discloses a three-dimension bone plate which is made of a stainless steel plate. The utility model is formed into a semicircular tube shape by pressing the stainless steel plate in a stamping mode. Round holes are arranged on the surface of the steel plate according to certain height difference; the middle section of the steel plate is provided with a hollow groove, a side rib and a middle rib which is convex in an arc shape. With the direction of the round holes, the semicircular tube shape of the steel plate, protrusions of the side rib and protrusions of the middle rib, the bone plate forms the three-dimension bone plate which has the function of fixing a three-dimension object, and is suitable for internal fixation of the intractable long bone fracture such as comminuted fracture, spiral fracture, fracture in an oblique shape, etc.
Description
This utility model relates to medical devices that a kind of human fracture of treatment uses, specifically can produce the blade plate of three dimensions (solid) internal fixation to the human body long bone fracture.
The internal fixation material kind of treatment long bone fracture is a lot, and commonly used so far has: " V " shape intramedullary needle, quincunx intramedullary needle, arc intramedullary needle, pressurization intramedullary needle; Fracture bone plate, pressurized bone plate, angle blade blade plate etc.These internal fixation materials all belong to one-dimensional or two-dimensional space is fixed, can play good fixation to some uncomplicated simple fracture, but can not satisfy the biomechanics requirement of long bone, also there are a lot of shortcomings, its major defect is: (1) intramedullary needle destroys vasoganglion and perimyelis in the pulp cavity, influences union of fracture; (2) intramedullary needle can cause fat embolism, jeopardizes patient's life; (3) intramedullary needle flexible, fracture, also can withdraw from voluntarily; (4) intramedullary needle can cause inserting needle position pain; (5) fracture bone plate and pressurized bone plate can rupture; (6) angle blade blade plate, fracture bone plate, pressurized bone plate and various types of intramedullary needle all can not play fixation to unstable fractures such as syntripsis, oblique fracture and spiral fractures, and the scope of application is restricted.Therefore, overcoming above shortcoming, design the blade plate that a kind of novel long bone of limbs is fractured, is the clinical urgency of orthopaedics problem to be solved.
The purpose of this utility model is a kind of biomechanics that meets long bone of limbs of design, is applicable to various types of long bone of limbs fracture, and fixed, is convenient to early functional exercise, makes the novel blade plate of the fast three dimensions of union of fracture (solid) internal fixation.
Realize that this utility model purpose is to adopt a block length shape stainless-steel sheet as blade plate sheet material, on steel plate by a certain percentage, the position keeps somewhere circular hole, steel plate is vertically struck out semi-circle tubular by the different length specification, be screwed in the circular hole with existing screw, it is fixing that long bone is produced the diesis intersection, promptly realizes the three-dimensional blade plate with three dimensions (solid) fixation.
Below in conjunction with Figure of description this utility model is further described:
Accompanying drawing 1 is a front view of the present utility model.
Accompanying drawing 2 is vertical views of the present utility model.
Accompanying drawing 3 is left views of the present utility model.
Accompanying drawing 4 is this utility model user mode ideographs.
Three-dimensional blade plate shown in 1,2 with reference to the accompanying drawings, it strikes out semi-circle tubular by the stainless-steel sheet (9) of a block length shape and forms, the length of steel plate (9) is selected not wait, and the thickness of steel plate is 2-3mm, can satisfy various age group or because of the needs of individual variation long bone fracture internal fixation treatment.
According to the three-dimensional blade plate shown in the accompanying drawing 1,3, the both end sides edge of steel plate (9) is oblique concavo-convex cambered surface, is petal.Shown in accompanying drawing 1, leave 8 circular holes on steel plate (9) face, be labeled as hole 1, hole 2, hole 3, hole 4 from top to bottom respectively according to the position of circular hole ... to the hole 8.Its mesopore 2, hole 6 be on the right side of steel plate (9), and hole 3, hole 7 are in the left side of steel plate (9).Hole 1, hole 4, hole 5, hole 8 are on the vertical median line of steel plate (9).2 in 1 in hole to the hole discrepancy in elevation a be 4-6mm, the discrepancy in elevation b that hole 2 to hole is 3 is 4-6mm, and the discrepancy in elevation c that hole 3 to hole is 4 is 4-6mm, and the discrepancy in elevation d that hole 5 to hole is 6 is 4-6mm, the discrepancy in elevation e that hole 6 to hole is 7 is 4-6mm, and the discrepancy in elevation f that hole 7 to hole is 8 is 4-6mm.Three-dimensional blade plate shown in 1,3 with reference to the accompanying drawings, the distance that its hole 1, hole 2, hole 3, hole 6, hole 7, hole 8 are positioned at steel plate (9) edge is 3mm.Three-dimensional blade plate shown in 1,2,3 with reference to the accompanying drawings, to leave left and right width in the stage casing of steel plate (9) be 5-7mm, be uneven in length about two trapezoidal dead slots (12), make steel plate form limit, left and right sides muscle (10) and 1 middle muscle (11), circular hole 1 to 4 is distributed in the upper end of steel plate (9), and circular hole 5 to 8 is distributed in the lower end of steel plate (9).Limit, left and right sides muscle (12) and middle muscle (11) outwards raise into arciform.Strike out the convex arcuate of muscle in semi-circle tubular and the limit muscle by steel plate (9), make blade plate have the blade plate of three-dimensional space.
Principle of the present utility model is the convex arcuate that steel plate is vertically struck out semi-circle tubular and limit muscle, middle muscle, constitute three dimensions, pass through the circular hole of different azimuth on the steel plate face again, make screw intersect fixing to the generation diesis of fracture, form three dimensions (solid) fixation, fracture is resetted, adopt three-dimensional blade plate internal fixation long bone fracture, its advantage is: (1) meets the biomechanics requirement of long bone, fixed, steel plate can not rupture, and does not need external fixation, is convenient to early functional exercise.(2) be adapted to intractable fixation of fractures such as comminuted fracture, oblique fracture, spiral fracture, be not subjected to the restriction of the scope of application.(3) help the healing of fracturing, shorten healing time, especially to comminuted fracture fixing after, can be observed the fixation case of the reduction of the fracture and driving fit and bone cips by trapezoidal dead slot.(4) three-dimensional blade plate does not contact the cortical bone of fracture, and vasoganglion in damaged bone inner membrance and the pulp cavity not helps that blood vessel is grown into and callus formation.
