Abstract
The invention discloses an n-shaped locking palm dorsal bone plate comprising a fixed short locking arm and a fixed long locking arm which are connected into the n shape integrally through a connecting locking arm. Auxiliary locking arms respectively extend from two ends of the connecting locking arm. A plurality of locking holes with internal threads are respectively formed in the fixed short locking arm, the fixed long locking arm, the connecting locking arm and the two auxiliary locking arms along lengths thereof, and the fixed short locking arm, the fixed long locking arm, the connecting locking arm and the two auxiliary locking arms are in arc-shaped arrangement matched with the radius surface respectively. The middle of the connecting locking arm is bent inwards, so that the connecting locking arm, the fixed short locking arm and the fixed long locking arm form an opening fitting with the size of the radius dorsal nodule. The bending angle of the connecting locking arm ranges from 144.5 degrees to 145.5 degrees, the included angle between the fixed short locking arm and the connecting locking arm ranges from 165.5 degrees to the 166.5 degrees, and the included angle between the fixed long locking arm and the connecting locking arm ranges from 169.5 degrees to 170.5 degrees. The n-shaped locking palm dorsal bone plate is premoulded according to the human body anatomy structure and has good locking effect, and excision of the radius dorsal nodule is avoided during use.
Description
Technical field
The present invention relates to medical instruments field, be specifically related to locking palm dorsal part π type blade plate.
Background technology
Radius far-end fracture refers to the cancellous bone fracture that is positioned at apart from radiocarpal joint face 2.5～3cm, at distal radius, has radius dorsal tubercle (Listei tuberosity).After radius far-end fracture, need to carry out resetting and carpal fusion of sclerite, the structure of the palm dorsal part blade plate that uses in the radius far-end fracture prosthesis at present is: be positioned at the T-shaped palm dorsal part blade plate body that conplane fixed arm forms by two, on two fixed arms, be provided with along its length respectively pulling force that some hole walls the are smooth hole of pressurizeing.the shortcoming of this palm dorsal part blade plate is: on the one hand, owing on palm dorsal part blade plate, being all the pulling force pressurization hole that hole wall is smooth, the doctor can only fixed form will be slapped the dorsal part blade plate and the radius far-end fracture position is fixed by pressurizeing, namely the supporting pulling force nail in hole will be slapped the dorsal part blade plate and the radius far-end fracture position is fixed by with pulling force, pressurizeing, pulling force is followed closely pressure-acting on palm dorsal part blade plate, the surface of bone that pressure makes to slap dorsal part blade plate and radius far-end fracture position fits, not only bad for affected part, recover like this, also easily make the postoperative constriction that produces in affected part of people, the simultaneously this poor stability of following closely the palm dorsal part blade plate after fixing with the mode that is fixed in pulling force pressurization hole by pulling force, easily come off, on the other hand, when fracture repair is performed the operation, reach to fracture site complete reset, carpal complete integration, need to make to slap the dorsal part blade plate fits with the surface of bone of radius far-end fracture position bone to a greater degree, but because this T-shaped palm dorsal part blade plate is easily encountered radius dorsal tubercle (Listei tuberosity) in fixation procedure is installed, in the fracture repair operation, need radius dorsal tubercle (Listei tuberosity) excision, thereby human body has been caused to secondary injury.
Summary of the invention
The purpose of this invention is to provide a kind of locking effect good, in installing and using process, need not excise the locking palm dorsal part π type blade plate of radius dorsal tubercle.
for achieving the above object, the present invention has adopted following technical scheme: described locking palm dorsal part π type blade plate, comprise fixedly locked galianconism, fixedly locked long-armed be connected lock arm, fixedly locked galianconism is with fixedly locked long-armed by being connected the be connected to form one distribution of shapes that is π shape of formula of lock arm, the two ends of described connection lock arm also respectively one extend a secondary locking arm, at fixedly locked galianconism, fixedly locked long-armed, connect on lock arm and two secondary locking arms respectively along length direction separately and be provided with the lock hole that some holes arm is offered female thread, the middle part of described connection lock arm bends inwards, make to connect lock arm and fixedly locked galianconism, fixedly locked long-armed three forms the opening identical with radius dorsal tubercle size, and fixedly locked galianconism, fixedly locked long-armed, connect lock arm and two secondary locking arms and along separately length direction, be the arc setting that fits with the radius surface of bone respectively, the bend inwards angle of rear formation of described connection lock arm is 144.5 °～145.5 °, described fixedly locked galianconism is 165.5 °～166.5 ° with the angle that is connected between lock arm, described fixedly locked long-armed with the angle that is connected between lock arm, be 169.5 °～170.5 °.
Further, aforesaid locking palm dorsal part π type blade plate, wherein: the bend inwards angle of rear formation of described connection lock arm is 145 °, and described fixedly locked galianconism is 166 ° with the angle that is connected between lock arm, described fixedly locked long-armed with the angle that is connected between lock arm, be 170 °.
Enforcement by technique scheme, the invention has the beneficial effects as follows: because locking palm dorsal part π type blade plate is the arc setting that can fit with the radius surface of bone, product has been carried out pre-moulding, make like this doctor in operation process, to product, carry out moulding operation again, thereby saved operating procedure, shortened operating time; And due to the lock hole with female thread that distributes on locking palm dorsal part π type blade plate, the doctor can lock locking palm dorsal part π type blade plate with radius by lock screw angulation fixed form mutually, locking effect is good, and Calcaneal plate stability in use is high, difficult drop-off; And because locking palm dorsal part π type blade plate has formed the opening identical with radius dorsal tubercle size, in operation process, just can excise again radius dorsal tubercle (Listei tuberosity), reduce the injury that in the operation process, human body is caused, also improved operation efficiency.
