Description
Technical field
The present invention relates to a kind of locking pressurization synthetism device and method for using thereof, be specially adapted to the human limb fracture fixation, belong to medical instruments field.
Background technology
Locked pressurized bone plate is to treat the most frequently used internal fixation apparatus of fracture at present both at home and abroad, and existing locked pressurized bone plate roughly has two kinds of structures, and a kind of is that pressurization hole and lock hole are independent separately, separately; Another kind is that pressurization hole and lock hole link together, and promptly through hole is partly overlapped by pressurization hole and lock hole and constitutes, and the center of the clearing end in the hole of promptly pressurizeing does not overlap with the center of lock hole; Though the pressurization hole and the lock hole of the blade plate of this kind structure link together; But its pressurization is independently with lock function, promptly needs to pressurize with ball screw earlier, in other lock hole, locks with lock screw then; Take out ball screw available as required lock screw locking at last.The blade plate of these two kinds of structures all needs to pressurize with ball screw earlier, and then locks with lock screw, and pressurization separates with locking to be carried out, complicated operation, and operating time is long; In addition, have too much through hole on the blade plate of first kind of structure, cause the intensity of blade plate relatively poor; Though and its pressurization hole of the blade plate of second kind of structure and lock hole link together, this through hole size longitudinally is bigger, has reduced the intensity of blade plate to a certain extent.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, provide a kind of and can realize that pressurization and locking settle, need not the locking pressurization synthetism device and the method for using thereof of separate operation at one go.
The technical solution adopted for the present invention to solve the technical problems is: a kind of locking pressurization synthetism device; Comprise blade plate body and screw, said blade plate body has a top surface and a basal surface that is used for the synthetism head, and said blade plate body is provided with one group of pressurization hole; Said pressurization hole connects said top surface and basal surface; One side in said pressurization hole is the initial end that begins to pressurize, and its opposite side is a clearing end of accomplishing pressurization, and wherein the hole wall of at least one pressurization hole clearing end is provided with screw thread; Said screw is arranged in the said pressurization hole, its head of screw be provided with said pressurization hole clearing end hole wall on the corresponding screw thread of screw thread.
Said pressurization hole is Long Circle, and the screw thread on its clearing end hole wall is circular arc.
Said pressurization hole is straight hole or taper hole, and said screw thread is straight thread or taper thread.
Said pressurization hole has a groove formation counterbore in the face of the top of said top surface.
Said groove is the spherical expansion groove.
The cone tank of said groove for forming through chamfering.
Be provided with screw thread on the hole wall of all pressurization hole clearing ends on the said blade plate body.
Said blade plate body is the strip blade plate body that a strip blade plate body or an end have the Special-Shaped Surface that can match with the bone surface shape.
Arrange along the longitudinal axis of blade plate body in described pressurization hole.
A kind of method of using described locking pressurization synthetism device; Step is following: a, an end of blade plate body is connected on the side of bone fracture position; Have at least a pressurization hole to be positioned at the opposite side of bone fracture position on it; Said screw is set in place in a pressurization hole of bone fracture position opposite side, and this screw is positioned at the initial end in pressurization hole; B, on skeleton, bore and said screw position corresponding positioning hole; C, screw and said locating hole are aimed at and inserted in this locating hole; D, rotary screw rotate its initial end from the pressurization hole, when screw turns is locked behind clearing end to clearing end.
Beneficial effect of the present invention: (one) is provided with screw thread on the hole wall of pressurization hole clearing end; Blade plate can pressurize earlier through lock screw like this, after lock screw turns to screwed hole, just can realize locking, has realized that promptly pressurization, locking settle at one go; Simple to operate, shortened operating time; (2) through hole number of the present invention is lacked than the through hole number of the blade plate of first kind of structure in the background technology, and through hole longitudinal size of the present invention is littler than the through hole of the blade plate of second kind of structure in the background technology, has improved the intensity of blade plate; (3) the present invention need not to use ball screw when pressurization, only needs existing lock screw can realize that pressurization, locking settle at one go, have reduced use cost; (4) in operation, also can use ball screw to implement pressurization as required.
