Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is a kind of novel universal bone holder specifically.
Technical background
What bone surgery was commonly used at present is three-jaw bone holder and two pawl bone holders, method of clamping difference when both use, but a lot of identical not enough points are arranged: (1) inserts difficulty, and tissue injury is big.The lower claw of two kinds of bone holders all needs to insert on one side from bone, need peel off more skeleton tissue on every side, and disorganization is big, and healing is slow.Two pawl bone holders particularly, it requires the radian of lower claw enough big, and is not so serious to the outer muscular tissue extruding of bone; (2) fixed effect of folding bone is bad.The limitation that the last lower claw of two kinds of bone holders contacts with bone, it is bad to cause rolling over the bone para-position, and the anti-bone displacement of bone holder, rotatory power are poor; (3) the steel plate fixed effect is bad.Bone surface is irregular, and fixedly difficulty is big with the folding bone to cause steel plate, and two kinds of bone holders are difficult to steel plate is applied effective chucking power, and the steel plate fixed effect is poor.Roll over bone bed knife and steel plate bed knife simultaneously all from the chucking power of handle, cause attending to one thing and lose sight of another easily like this; (4) boring is inconvenient, and the spatial form of two kinds of bone holders has limited the following brill position of brace, and brace bores difficulty down under a lot of situations.At present also have a kind of novel bone holder on the surgical operation, though it can solve the subproblem that above two kinds of bone holders exist preferably, because it self, cause it still to come with some shortcomings: Knock-Down Component was too much when (1) this bone holder used.Because bone holder is to be used for surgical operation, too much Knock-Down Component can produce the omission risk, increases the risk of operation; (2) the axial overlay length of the bone of this bone holder corpus unguis is limited.Have many comminuted fracture in the fracture case, at this moment require the axial overlay length long enough of bone of bone holder corpus unguis, and the axial overlay length of the bone of novel bone holder corpus unguis is corpus unguis self width, it can not effectively finish the clamping to broken bone.This utility model sets out at above problems, has solved existing problem preferably, and designs simple and easyly, and operation is convenient, highly versatile.
The utility model content
This utility model purpose is to provide a kind of novel universal bone holder.
The technical solution of the utility model is: a kind of novel universal bone holder is characterized in that it is made up of retained part and control section.Wherein, retained part mainly comprises fore paw one (13), fore paw two (2), rear solid end one (14), rear solid end two (3), pressure head one (12), pressure head two (30), steel plate (11), fore paw one (13) and fore paw two (2) parallel arranging, rear solid end one (14) and rear solid end two (3) parallel arranging, fore paw one (13) and rear solid end one (14) parallel over against, control section mainly comprises laterally draws road one (18), laterally draw road two (17), vertically draw road one (18), vertically draw road two (26), about slide screw mandrel (6), upper handle (9), lower handle (15), wherein laterally draw one (18) with laterally stroke road two (17) parallel arrangements are also vertical with gripping object, and vertically draw one (18) with vertically stroke road two (26) parallel arrangements are also parallel with gripping object, about slide and be equipped with locking nut (8) on the screw mandrel (6), upper handle (9) is connected with the horizontal road of drawing by connector (27), and lower handle (15) then is connected with vertical road one (18) formation of drawing by connecting rod (4).
The beneficial effects of the utility model are:
(1) the slider-crank mechanism principle is applied in the clamping of bone, and people's finger is firmly little like this, and the corpus unguis active force is big, and corpus unguis is to the bone formula clamping of filling the span of a man's arms, and clamping better effects if like this is more reliable.And corpus unguis inserts simply, and is little to tissue injury.
(2) space structure of this bone holder concentrates on the side of bone, but not the top of bone, boring has stayed enough spaces to brace like this.
(3) steel plate is fixing reliable.Steel plate fixedly is to press down steel plate by two pressure heads to finish separately, separates with the clamping of bone operation and carries out, and avoids two operations to attend to one thing and lose sight of another, and pressure head and contacting of steel plate be face with face contact effective like this sidesway that prevents steel plate.
(4) fore paw two, rear solid end two can left and right sides slippages on slide rail separately, can regulate the axial clamping length of bone of corpus unguis so according to actual needs.
