Description

The bridge-type serial blade plate that pressurizes

This utility model belongs to orthopaedics medical treatment equipment, is blade plate series of products, is applicable to orthopaedics extremity different parts type treatment of fractures.

According to the knowledge of the applicant, blade plate mainly is from material at present, three aspects of form and performance are changed and are advanced, development is the variation of form faster, and the variation of form is for blade plate more perfect and suitable Human Physiology requirement on performance, bridge-type blade plate ZL95,213432,2, then be advanced on form at present, rationally, the blade plate that is fit to Human Physiology and biomechanical principle on the performance, it has not only reduced the occlusion effect of blade plate itself, and make the blade plate stress concentration around screw through stressed redistribution of knuckle face and round table surface design, thereby reduced stress-shielding effect, the resistant to bending stresses and the torsional rotation force of blade plate have been increased again, therefore development prospect is considerable, but bridge-type blade plate form is single at present, has only one type on the straight shape type in six holes, can not adapt to the demand that extremity fracture occurs in various positions and all kinds fracture sometimes, the scope of application is narrow, the bridge-type blade plate does not have the function that present blade plate requirement has pressurization in addition, on performance, be weak again, therefore still not comprehensive in practical application.

The purpose of this utility model is at bridge-type blade plate ZL95,213432, improved perfect on 2 the basis, make it by the straight shape form in single six holes, change over by the straight shape type of four holes to octal, elevation end-type, " S " end type, ten holes straight shape type polymorphic type multi-series blade plate, the tighten up a screw diameter in nail hole and on the form of the cancellous bone screw on the end and specification, also being improved of enlarged portion in elevation angle end and " S " end type simultaneously, make the pressurize advantage of the existing bridge-type blade plate of serial blade plate of bridge-type itself, has polymorphic type again, the scope of application is extensive, the serial blade plate of perfect in shape and function, thereby applicable to the needs of various positions of extremity fracture and type.

The bridge-type of this utility model design serial blade plate that pressurizes, by four hole groups, five hole groups, six hole groups, the seven apertures in the human head group, the octal group, six series of the straight type group in ten holes are formed, four hole groups have straight shape type again to the octal group, elevation end-type, three types of " S " end type, elevation end-type, " S " end type all designs according to the epiphysis form, end is tightened up a screw and is followed closely the hole increasing, and the screw that uses is mariages tooth spongiosa nail, increase by an attached hole between this two classes end top table top and the adjacent table top and go up fixed stability and motility to increase end, each blade plate by one side for the knuckle face of contact bone side and the flat face upper table surface that another side is the synthetism side constitute, formation two is thin, the arch bridge sample of thick middle, each blade plate all has the pressurization hole, and the table top on the flat face is oval-shaped table-board relatively, each hole of pressurizeing is the AO hole of pressurizeing automatically, promptly sinking recessed at knuckle face nailing medicated cap half is that centration is deepened, and this promptly increases the pressurization function of blade plate, all vertical nick of the table top of contact bone side, to adapt to the form of bone, thereby can attach in the time of fixedly on the bone, the table top of each blade plate is divided equally two groups and is distributed in the blade plate two ends, and adjacent two table tops are staggered between every group;
