Description
Technical field
This utility model relates to a kind of medical equipment that is used for the treatment of fracture, especially relates to the external reduction fixture device of a kind of olecranal fracture.
Background technology
Olecranal fracture is the more common interior fracture of elbow joint, requires parking position accuracy, reliable fixing during treatment, and practises as far as possible in early days elbow joint function.The Therapeutic Method of olecranal fracture is more, and wherein external is fixedly a kind of method preferably.The existing external reduction fixture device of several olecranal fractures used, although reset, substantially can meet the demands, but its structure is mostly too complicated, cause the production of product and use inconvenience, simultaneously these external fixators stability, reliability fixing to fractures is poor, and therefore the actual effect of using is all not ideal enough.
The utility model content
The technical problems to be solved in the utility model is: for solve the existing external reduction fixture device complex structure of olecranal fracture, production and use inconvenience, while using to fractures the fixing poor problem of reliability, and provide a kind of simple in structure, production and easy-to-use, cost is low, while using to the fixing external reduction fixture device of accurate olecranal fracture that reliably resets of fractures simultaneously.
This utility model solves the technical scheme that its technical problem adopts: the external reduction fixture device of a kind of olecranal fracture, include bar shaped hook plate and nail, the bar shaped hook plate has crotch section and flat segments, be provided with elongated slot in the bar shaped hook plate, the upper semisection of nail has been attacked nut thread, lower semisection has been attacked the wood snail stricture of vagina, nail is through being arranged in the elongated slot of bar shaped hook plate flat segments and being fixed on elongated slot by nut, the tail end of bar shaped hook plate flat segments has the tapped through hole communicated with elongated slot, placed the pressurization screw rod in tapped through hole, the head of pressurization screw rod holds out against with the nail be fixed in elongated slot, the tail end of pressurization screw rod is with swing handle.
The using method of the external reduction fixture device of this olecranal fracture is as follows: nail is fixed in the elongated slot of bar shaped hook plate flat segments by nut on the one hand, wood snail stricture of vagina by self is fixed in ulna on the one hand, screwing the pressurization screw rod moves the bar shaped hook plate, thereby the gib head of bar shaped hook plate crotch section holds out against olecroanon gradually, complete the reliable of olecranal fracture fixed.
In order to make fixing more firm at 1/3 of bar shaped hook plate, thereby more firm more fixing olecranal fracture section also has the auxiliary fixing bone pin consistent with Bone nail structure, and auxiliary fixing bone pin also is fixed in the elongated slot of bar shaped hook plate flat segments by nut.The occupation mode of auxiliary fixing bone pin is consistent with nail.
The crotch section of described bar shaped hook plate is cut apart by elongated slot fully and is formed the gib head of two symmetries.The advantage that the crotch section of bar shaped hook plate forms " double hook head " is, make gib head can be better fixing olecroanon, prevent that the olecranal fracture piece from deflecting.
Say further again, also there is the auxiliary fixing bone pin of olecroanon, the upper semisection of the auxiliary fixing bone pin of olecroanon has been attacked nut thread, the lower semisection smooth surface, be positioned at the dual-side of elongated slot of crotch section in the bar shaped hook plate along being formed with inclined-plane or continuous sphere tooth nest, the auxiliary fixing bone pin of olecroanon is fixed in the elongated slot of bar shaped hook plate crotch section by the Ball faced nut be complementary with above-mentioned inclined-plane or sphere tooth nest.The complicated olecranal fracture (as olecranal fracture rotation displacement, shift separation, comminuted fracture etc.) rare for some is while being resetted fixedly, also need to overcome the tension force of olecranal fracture line dorsal part, in this case, just need to assist fixing with the auxiliary fixing bone pin of olecroanon.While using the auxiliary fixing bone pin of olecroanon, the auxiliary fixing bone pin of olecroanon passes the elongated slot of bar shaped hook plate crotch section and fixes by Ball faced nut, and its tip leans the olecranal fracture piece through after skin.
The beneficial effects of the utility model are: the external reduction fixture device structure of this olecranal fracture is very simple, produces and easy-to-use, cheap, to the fixation of fractures, reliable, little to soft tissue injury during use, reset accurately simultaneously, and complete function.

The specific embodiment
The external reduction fixture device of a kind of olecranal fracture, as Fig. 1, shown in Fig. 2, it includes bar shaped hook plate 1 and nail 2, bar shaped hook plate 1 has crotch section and flat segments, be provided with elongated slot 1-1 in bar shaped hook plate 1, the upper semisection of nail 2 has been attacked nut thread, lower semisection has been attacked the wood snail stricture of vagina, nail 2 is through being arranged in the elongated slot 1-1 of bar shaped hook plate 1 flat segments and being fixed on elongated slot 1-1 by nut, the tail end of bar shaped hook plate 1 flat segments has the tapped through hole communicated with elongated slot 1-1, placed pressurization screw rod 3 in tapped through hole, the head of pressurization screw rod 3 holds out against with the nail 2 be fixed in elongated slot 1-1, the tail end of pressurization screw rod 3 is with swing handle 3-1.
The using method of the external reduction fixture device of this olecranal fracture is as follows: as shown in Figure 3, nail 2 is fixed in the elongated slot 1-1 of bar shaped hook plate 1 flat segments by nut on the one hand, wood snail stricture of vagina by self is fixed in ulna on the one hand, screwing pressurization screw rod 3 moves bar shaped hook plate 1, thereby the gib head of bar shaped hook plate 1 crotch section holds out against olecroanon gradually, complete the reliable of olecranal fracture fixed.
In order to make bar shaped hook plate 1 more firm fixing of 1/3, thereby more firm more fixing olecranal fracture, also have the auxiliary fixing bone pin 4 consistent with nail 2 structures, auxiliary fixing bone pin 4 also is fixed in the elongated slot 1-1 of bar shaped hook plate 1 flat segments by nut.The occupation mode of auxiliary fixing bone pin 4 is consistent with nail 2.
The crotch section of bar shaped hook plate 1 is cut apart by elongated slot 1-1 fully and is formed the gib head of two symmetries.The crotch section of bar shaped hook plate 1 form " double hook head " can make gib head can be better fixing olecroanon, prevent that the olecranal fracture piece from deflecting.
The external reduction fixture device of this olecranal fracture also has the auxiliary fixing bone pin 5 of olecroanon, the upper semisection of the auxiliary fixing bone pin 5 of olecroanon has been attacked nut thread, the lower semisection smooth surface, be positioned at the dual-side of elongated slot 1-1 of crotch section in bar shaped hook plate 1 along being formed with inclined-plane or continuous sphere tooth nest 1-2, the auxiliary fixing bone pin 5 of olecroanon is fixed in the elongated slot 1-1 of bar shaped hook plate 1 crotch section by the Ball faced nut 6 be complementary with above-mentioned inclined-plane or sphere tooth nest 1-2.The complicated olecranal fracture (as olecranal fracture rotation displacement, shift separation, comminuted fracture etc.) rare for some is while being resetted fixedly, also need to overcome the tension force of olecranal fracture line dorsal part, in this case, just need to assist fixing with the auxiliary fixing bone pin 5 of olecroanon.While using the auxiliary fixing bone pin 5 of olecroanon, olecroanon assists fixing bone pin 5 through the elongated slot 1-1 of bar shaped hook plate 1 crotch section fixing by Ball faced nut 6, and its tip leans the olecranal fracture piece through after skin.
