Abstract

A bone fracture plate with combination locking holes belongs to medical appliances, wherein the middle of the bone fracture plate is thick, the two ends of the bone fracture plate are thin, so the stress is dispersed, the implantation is facilitated, a plurality of structural holes are arranged on the bone fracture plate at intervals and longitudinally penetrate through the bone fracture plate, so convenience is provided for fixing different parts through different screws during the orthopedic operation; arc grooves are arranged at the bottom to reduce the stress shielding on the bone, no pressure is generated on the periosteum, so the periosteum is prevented from being damaged, the fracture healing period is shortened, and the reset loss of the period I and the period II is reduced; location holes are arranged for locating and fixing the bone fracture plate and fixing comminuted bone pieces; and a gap is reserved between the bone fracture plate and the surface of the bone, so no pressured is generated between the locked bone fracture plate and the bone cortex, and blood circulation is ensured to be normal.

Description

Have the blade plate that makes up lock hole

Technical field

This utility model belongs to a kind of medical apparatus and instruments, particularly a kind of blade plate that makes up lock hole that has.

Background technology

Blade plate is the equipment commonly used that connects the skeleton broken ends of fractured bone in the bone surgery, and the bone that is mainly used in patient's fracture couples together, for knochenbruch provides favourable form support, so that knochenbruch heals early.Traditional blade plate action principle is to select blade plate for use according to different parts, and adopts plain screw or forcing screw to fix.Because blade plate, very easily causes the local osteoporosis of skeleton to the stress that blocks of skeleton and fractures, the screw of blade plate and outfit also becomes flexible owing to the skeleton delayed union or ruptures.In addition, combine too closely between bone and the blade plate, can make blade plate compress periosteum, influence the periosteum blood circulation, cause bone does not connect or periosteum necrosis.

The utility model content

The purpose of this utility model is to overcome above-mentioned defective, and a kind of blade plate that makes up lock hole that has is provided, and it is rational in infrastructure, and is easy to use, and is stressed even, is difficult for loosening.

The purpose of this utility model is achieved through the following technical solutions:

A kind of blade plate that makes up lock hole that has, it is porous and the lengthy motion picture shape that meets with the skeleton profile, be provided with flat segments and bending section, bending section has the amount of deflection that meets with the skeleton profile, and and flat segments between with the curved surface transition, curved surface and limbs warp architecture match, it is characterized in that: said blade plate middle part is thick, two ends are thin, at interval spherical pore, screw combination bore and locating hole are set on blade plate, and vertically run through blade plate; Be provided with a plurality of arc grooves in its bottom surface.

A kind of blade plate that makes up lock hole that has, it is porous and the lengthy motion picture shape that meets with the skeleton profile, it is characterized in that: said blade plate middle part is thick, and two ends are thin, spherical pore, tapered tread hole, pressurization hole and locating hole are set on blade plate at interval, and vertically run through blade plate; Be provided with a plurality of arc grooves in its bottom surface.

The beneficial effects of the utility model are:

1, on the blade plate locating hole is set, is titanium silk packing hole, when being convenient to perform the operation to the positioning and fixing of blade plate and fixing to comminuted bone piece; And can make blade plate and bone surface keep certain interval, making between locking bone fracture plate and cortical bone does not have plus-pressure, guarantees that blood fortune is normal;

2, at the bottom surface of blade plate arc groove spaced apart, to reduce the stress shielding to skeleton, so periosteum is not produced pressure, the protection periosteum is not destroyed, and is heavy and shorten the union of fracture phase, reduces I phase and II phase effectively to reset and lose;

3, at interval many structure hole are set on the blade plate, the different screw of the interior employing of bone surgery of being convenient to different parts is fixed;

4, it is thick that blade plate is designed to the middle part, and the two ends thin structure disperses stress, and is convenient to implant.

The specific embodiment

Embodiment 1: a kind of blade plate structure that makes up lock hole that has, it is porous and the lengthy motion picture shape that meets with the skeleton profile, be provided with flat segments and bending section, bending section has the amount of deflection that meets with the skeleton profile, be provided with flat segments 1 and bending section part 2, curved surface transition between disconnected part 2 of bending and the flat segments 1, curved surface and limbs warp architecture match, said blade plate 1 middle part is thick, two ends are thin, at interval spherical pore 4 and locating hole 5 are set in the disconnected part 2 of the bending of blade plate 1, in flat segments 1 screw combination bore 9 are set, in the end of flat segments locating hole 5 is set, and vertically runs through blade plate; Be provided with a plurality of arc grooves 3 in its bottom surface.

Embodiment 2: a kind of blade plate structure that makes up lock hole that has, it is a porous flat integrative-structure, comprise flat segments 1, its middle part is thick, two ends are thin, at blade plate 1 one ends a plurality of spherical pores 4 are set, and pressurization hole 7, tapered tread hole 6 are set at interval at the middle part, the other end at blade plate 1 is provided with locating hole 8, and vertically runs through blade plate; Be provided with a plurality of arc grooves 3 in its bottom surface.

Select conical cap and the ball medicated cap double end or the single head bone screw screw-in blade plate of Flos Mume groove or six square grooves for use, the head of a nail threaded portion that screwed hole and bone screw are put into blade plate matches.

More than two kinds of blade plate structures, can adapt to the bone surgery various disease conditions, postoperative does not influence the growth of periosteum, bone stump growth is fast, and makes patient's early recovery.
