Abstract

The utility model provides a constant magnetic field spoon shape bone-setting board used for the internal fixation of fracture of the area of the metaphysis of four limbs. The utility model is in a spoon shape which is in coincidence with the structural shape of the cut area of the metaphysis of four limbs. When the existing bone-setting board carries out internal fixation in the bone fracture area of the metaphysis of four limbs, the problems of the artificial bent, easy breakage of the bone-connecting board, the easy movement and displacement of the bone fracture end can be solved. With the constant magnetic material, the utility model can continually produce constant magnetic field to promote the immediate union of the bone fracture. The utility model has a function of alleviating pain and detumescence, which does not need gypsum to carry out the auxiliary external fixation.

Description

Constant magnetic field spoon shape bone-setting board of skeleton end fracture

This utility model relates to a kind of permanent magnetic field spoon shape blade plate of improved extremity metaphysis fracture, particularly a kind of internal fixation blade plate that is used for zone fracture under zone fracture on the condyle of femur, femoral intertrochanteric zone fracture and the tibia condyle, on the ankle.

Existing blade plate divides common and pressurizes two kinds; be linear; be mainly used in long bone of limbs and do the internal fixation of fracture; but the metaphysis join domain is fractured; as femoral inferior segment and condyle of femur join domain fracture, zone fracture between the femur upper segment tuberosity is under the tibia condyle; zone fracture on the ankle; use common or the pressurized bone plate effect is fixed; just often seem very difficult, this is that existing blade plate is linear because be a spoon shape arcuate structure between backbone and the epiphysis; during use; to carry out artificial bending earlier, just can fix then, but the so metal structure that usually can destroy blade plate itself; after a period of time; blade plate is easily further crooked, even fracture, thereby causes the fracture end activity; displacement; angulation deformity; and because the existing equal lack perseverance magnetic of blade plate material can not be produced permanent magnetic field effect, so also need Gypsum Fibrosum to be assisted as external fixation; set time is generally taken 3～4 months, and adverse consequencess such as obstacle appear in easy like this amyotrophy or the function of joint of causing.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provides a kind of easy to use, and internal fixation is solid, can promote fracture heals in early days, alleviates the patient suffering, does not need Gypsum Fibrosum to make the auxiliary novel blade plate of external fixation.

The technical solution of the utility model is: blade plate is made with sheet metal, and characteristics are to open a sulculus at any end of blade plate, permanent magnetic material 1 is packed in the groove, then sealing; Blade plate is struck out a spoon shape, and wherein an end bores 4～6 pressurization holes 2 by linear array, and the other end is pressed cross and arranged 4 fixing holes 4 of brill.

Because the shape of this novel blade plate meets special anatomical structure key and the epiphysis zone, and permanent magnetic material is housed, sustainable production stationary magnetic field effect, compare with known blade plate, internal fixation to the metaphyseal region fracture has anti-jail easy to use, firm, the advantage of healing ahead of time has the function of alleviating pain and detumescence and almost not increase of cost to hindering limb.

Below with reference to accompanying drawing this utility model is described in further detail.

Fig. 1 is the sketch map that this utility model provides, and Fig. 2 is a profile.

Referring to Fig. 1, whole blade plate be shaped as a spoon shape, an end of broad is " a spoon head " 5, a narrower end is that " the shank of the key " 3, one concave grooves run through whole blade plate; Be drilled with 4 fixing holes 4 that are crossing distribution on " spoon head " of blade plate 5, the aperture is 42mm, and " the shank of the key " 3 central authorities are drilled with 5 shapes pressurization holes 2, ellipse garden that are arranged in a linear, Kong Changwei 6mm, Kong Kuanwei 4.2mm; Blade plate is made with a punching press of the corrosion resistant plate boring of 3mm; An openning that 20mm is dark is severed at top at the shank of the key 3 ends of stamping forming blade plate, the Magnet thin slice of corresponding size is embedded in the openning, then sealing.

Through above-mentioned steps, just can draw this permanent magnetic field spoon shape blade plate.When use this novel blade plate as condyle of femur on zone fracture when making internal fixation, the shank of the key 3 parts of blade plate are aimed at the outside of femoral inferior segment, spoon 5 part are aimed at the ectocondyle of condyle of femur, lay blade plate, then with bone screw by pressurization hole 2 on the blade plate and fixing hole 4, blade plate is fixed on the bone lattice firmly, because the shape of this blade plate conforms to regional bone lattice anatomical structure on the condyle of femur, blade plate is fixed firm and solidly, be not prone to the situation of the movable displacement of fracture end, lay Magnet in addition, blade plate has a constant magnetic field, by the permanent magnetic field effect of its production, just can promote the growth of bone lattice effectively, the healing of fracture ahead of time, and the function of alleviating pain and detumescence is arranged to hindering limb.

Claims

1, a kind of metaphysis permanent magnetic field spoon shape blade plate of fracturing is made by sheet metal, and some apertures are arranged on the plate, and it is characterized in that: any end at blade plate is embedded with permanent magnetic material 1.

2, blade plate according to claim 1 is characterized in that: the shape of blade plate is made a spoon shape, and an end of blade plate has some pressurization holes 2 that are arranged in a linear, and the other end of blade plate has 4 fixing holes 4 that are cross arrangement.
