Abstract
The utility model discloses a locking palm back side pi-shaped bone plate which comprises a fixed locking short arm and a fixed locking long arm, wherein the fixed locking short arm and the fixed locking long arm are connected through a connecting locking arm to form an integral pi shape. The two ends of the connecting locking arm are integrally provided with two auxiliary locking arms respectively in an extending mode, and the fixed locking short arm, the fixed locking long arm, the connecting locking arm and the two auxiliary locking arms are respectively provided with a plurality of locking holes with inner threads in the respectively length directions and are arranged to be arc to be attached to the face of the radius respectively. The middle of the connecting locking arm is bent inwards, and therefore the connecting locking arm, the fixed locking short arm and the fixed locking long arm form an opening which is equal to the a node of the back side of the radius in terms of size. The angle after the connecting locking arm is bent ranges from144.5 degrees to 145.5 degrees, the included angle of the fixed locking short arm and the connecting locking arm ranges from 165.5 degrees to 166.5 degrees, and the included angle of the fixed locking long arm and the connecting locking arm ranges from 169.5 degrees to 170.5 degrees. According to the locking palm back side pi-shaped bone plate, pre-shaping which conforms to a human anatomy structure is performed, the locking effect is good, and the node of the back side of the radius does not need to be excised when the locking palm back side pi-shaped bone plate is used.
Description
Technical field
This utility model relates to medical instruments field, is specifically related to locking palm dorsal part π type blade plate.
Background technology
Radius far-end fracture refers to the cancellous bone fracture being 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 reset and the carpal fusion of sclerite, the structure of the palm dorsal part blade plate using in radius far-end fracture prosthesis is at present: be positioned at the T-shaped palm dorsal part blade plate body that conplane fixed arm forms by two, be provided with along its length respectively pulling force that some hole walls the are smooth hole of pressurizeing on two fixed arms.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, doctor can only be fixed palm dorsal part blade plate and radius far-end fracture position by pressurization fixed form, by pressurizeing with pulling force, the supporting pulling force nail in hole will be slapped dorsal part blade plate and radius far-end fracture position is fixed, pulling force is followed closely pressure-acting on palm dorsal part blade plate, pressure fits the surface of bone of slapping dorsal part blade plate and radius far-end fracture position, 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 the complete reset to fracture site, carpal complete integration, need to make to slap 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 fracture repair operation, need radius dorsal tubercle (Listei tuberosity) excision, thereby human body has been caused to secondary injury.
Utility model content
It is good that the purpose of this utility model is to provide a kind of locking effect, need not excise the locking palm dorsal part π type blade plate of radius dorsal tubercle in installing and using process.
For achieving the above object, this utility model 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, on connection lock arm and two secondary locking arms, edge length direction is separately provided with the lock hole that some holes arm is offered female thread respectively, 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 length direction separately, be the arc setting fitting with radius surface of bone respectively, the angle forming after described connection lock arm bends inwards is 144.5 °～145.5 °, described fixedly locked galianconism is 165.5 °～166.5 ° with the angle being connected between lock arm, described fixedly locked long-armed be 169.5 °～170.5 ° with the angle being connected between lock arm.
Further, aforesaid locking palm dorsal part π type blade plate, wherein: the angle forming after described connection lock arm bends inwards is 145 °, and described fixedly locked galianconism is 166 ° with the angle being connected between lock arm, described fixedly locked long-armed be 170 ° with the angle being connected between lock arm.
By the enforcement of technique scheme, the beneficial effects of the utility model are: because locking palm dorsal part π type blade plate is the arc setting that can fit with 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 female lock hole of tool distributing on locking palm dorsal part π type blade plate, 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 is in use 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 in operation process, human body being caused, also improved operation efficiency.
