Description

A kind of fracture internal fixation steel plate

Technical field

This utility model relates to the fracture fixation device field, specifically is a kind of fracture internal fixation steel plate.

Background technology

At present, clinically in the human limb surgical treatment of fracture, use steel plate that knochenbruch is carried out internal fixation mostly.This steel plate is a strip, is drilled with some through holes on it.To knochenbruch fixedly the time, the both sides of fracture place of knochenbruch also be drilled with steel plate on the corresponding hole of through hole, by means of screw steel plate is fixed on the knochenbruch, to realize the fixing of knochenbruch.But there are a lot of problems in use in this internal fixation steel plate: 1, the comminuted fracture sliver of some fracture patient is more, with the existing steel plate that is provided with in spacer bolt hole fixing fixedly the time, can cause fracture blood fortune to destroy, cause the tabs necrosis, postpone the callus stroke, even can cause the fracture of fixation steel plate bolt hole place; 2, the inner surface of steel plate is very smooth in the fracture, behind screw-driving, on the inner surface of steel plate periosteum that is pressed in the bone outside tightly, seriously hindered the blood circulation of periosteum, influence easily sclerotin healing, severe patient even can cause the periosteal tissue necrosis is unfavorable for patient's early recovery; 3, the profile of bone generally is not very regular, and the internal fixation steel plate inner surface is very smooth, after steel plate and knochenbruch are fixed together, causes unbalance stress easily, causes steel plate and screw extraction.Simultaneously, this internal fixation steel plate can't be implemented pressurization to the fracture location of knochenbruch when knochenbruch is carried out internal fixation, and the fracture location of fixing back knochenbruch tends to exist certain clearance, influences the healing of knochenbruch easily, and one time cure rate is not high.

Summary of the invention

The purpose of this utility model is to provide a kind of fracture internal fixation steel plate, it can solve the deficiency that exists in the known technology, by the opposite inclination screw hole of incline direction is set, can rely on the interlocking structure of steel plate self to achieve a fixed connection, be provided with bone screw holes, can utilize nail that the comminuted fracture sliver is fixed, thereby reach the purpose that improves curative effect.

This utility model for achieving the above object, be achieved through the following technical solutions: a kind of fracture internal fixation steel plate, comprise fixation steel plate and with the supporting screw of fixation steel plate, fixation steel plate is a strip, the fixation steel plate medial surface is the cambered surface of indent, several the first inclination screw holes and the second inclination screw hole are set on the fixation steel plate at interval, the incline direction of the first inclination screw hole and the second inclination screw hole is opposite, mounting screw in the screw hole, several bone screw holes are set on the fixation steel plate, nail is installed in the bone screw holes.

Described fixation steel plate one side is provided with the pressure strip of evagination, and keeping parallelism between pressure strip and fixation steel plate is provided with the means of vertical screws hole on the pressure strip, and mounting screw in the means of vertical screws hole is provided with several bone screw holes on the pressure strip.

The beneficial effects of the utility model are: by the opposite inclination screw hole of incline direction is set, can rely on the interlocking structure of steel plate self to achieve a fixed connection, need not to utilize the frictional force of bone to fix, can make inner surface of steel plate and bone surface keep certain interval, can not exert an influence to cortex blood fortune, eliminate the ill effect that steel plate contacts with bone weight, greatly improved the recovery of blood fortune and periosteum; Bone screw holes is set on internal fixation steel plate, utilizes the fixing fracture of nail rupture diaphragm, prevent that fracture blood fortune destruction, tabs necrosis and callus formation from postponing, protection internal fixation steel plate screw hole is not damaged; Be provided with the evagination pressure strip, can implement pressurization to fracture place of knochenbruch, fracture place of knochenbruch is closely linked to each other, improve one-time cure rate etc. by screwing the screw on the pressure strip.

Label shown in the accompanying drawing: 1, bone screw holes; 2, fixation steel plate; 3, the first inclination screw hole; 4, the second inclination screw hole; 5, screw; 6, nail; 7, cambered surface; 8, means of vertical screws hole; 10, pressure strip.

The specific embodiment

Below in conjunction with specific embodiment, further set forth this utility model.Should be understood that these embodiment only to be used to this utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications this utility model after the content of having read this utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

A kind of fracture internal fixation steel plate described in the utility model, agent structure comprisefixation steel plate 2 and with the supporting screw 5 of fixation steel plate.Describedfixation steel plate 2 is strips, andfixation steel plate 2 medial surface are cambered surfaces 7 of indent, and this inner concave arc surface can reduce the compressing of 2 pairs of bone surface of fixation steel plate, prevents that fracture blood fortune is affected, and improves and recovers efficient.The incline direction that several firstinclination screw holes 3 and the second inclination screw hole, 4, the firstinclination screw holes 3 and the second inclination screw hole 4 are set onfixation steel plate 2 at interval is opposite, mounting screw 5 in the screw hole.By the first oppositeinclination screw hole 3 of incline direction and the second inclination screw hole 4 are set, can rely on the interlocking structure offixation steel plate 2 self to achieve a fixed connection, need not to utilize the frictional force of bone to fix, thereby makefixation steel plate 2 inner surfacies and bone surface keep certain interval, can not exert an influence to cortex blood fortune, eliminate the ill effect thatfixation steel plate 2 contacts with bone weight, greatly improved the recovery of blood fortune and periosteum.Severalbone screw holes 1 are set onfixation steel plate 2; nail 6 is installed in thebone screw holes 1;bone screw holes 1 can be positioned at each position on thefixation steel plate 2; be as the criterion not influence screw 5 installations; in the use; utilize nail 6 fixing fracture rupture diaphragms, prevent that fracture blood fortune destruction, tabs necrosis and callus formation from postponing, and can protect screw hole not to be damaged.

The further embodiment of this utility model is: describedfixation steel plate 2 one sides are provided with thepressure strip 10 of evagination, 2 keeping parallelisms ofpressure strip 10 and fixation steel plate, means ofvertical screws hole 8 is set on thepressure strip 10, and mounting screw 5 in the means ofvertical screws hole 8 is provided with severalbone screw holes 1 on the pressure strip 10.In the present embodiment, can implement pressurization to fracture place of knochenbruch by screwing the screw 5 on thepressure strip 10, thereby fracture place of knochenbruch is closely linked to each other, improve one-time cure rate.
