Abstract
The invention belongs to the field of medical equipment and discloses an external fixation clamp allowing multidirectional adjustment. The external fixation clamp allowing multidirectional adjustment is provided with a screw fixing clamp (1) which is provided with an eccentric locking switch (2), a universal ball head (4) which is provided with a rotary knob type locking switch (5) and an extension arm (3) which is provided with an expansion type locking switch (6). The external fixation clamp allowing multidirectional adjustment is characterized in that the screw fixing clamp (1) and the universal ball head (4) can be firmly connected with a screw and an external fixing frame connecting rod respectively. Relative angels between the screw which is fixed inside the screw fixing clamp (1) and the external fixing frame connecting rod which is connected to the universal ball head (4) can be changed in a multidirectional mode due to multidirectional adjustment of the eccentric locking switch (2), the rotary knob type locking switch (5) and the expansion type locking switch (6) and the distance between the screw and the external fixing frame connecting rod can be adjusted by adjusting the length of the extension arm (3). The external fixation clamp allowing multidirectional adjustment has the advantages of being simple in structure and convenient to operate, allowing multidirectional continuous adjustment and the like.
Description
Technical field
The invention belongs to medical instruments field, relate in Orthopedic Clinical the fixture with angle and distance between multidirectional adjustment exterior fixation bracket connecting rod and hold-down screw, especially can for when orthopedist provides exterior fixation bracket to fix fracture between support and hold-down screw the continuous setup of multi-angle, different distance provide convenience.
Background technology
Exterior fixation bracket is the conventional apparatus for the treatment of fracture, and its and bone directly contact or the part that connects becomes the most frequently used form because screw-type structure is combined firm with sclerotin, and the connection of screw and external fixer main body adopts multi-form fixture more.The exterior fixation bracket fixture applied in current Orthopedic Clinical is many can the adjustment of travel direction, but the limited adjustment being limited to several orientation angle of its adjustment more, be screwed into the position in bone due to hold-down screw, direction varies with each individual, the position that exterior fixation bracket or coupled equipment only can be determined along fracture proximal screw far away is installed, and can not arbitrarily change.Along with the development of orthopaedics correlation technique, being connected in exterior fixation bracket is progressively applied to clinical for the equipment of Inspect and control fracture end mechanical change and utensil, in order to Measurement accuracy and control fracture end mechanical change situation, require that the position to equipment is installed accurately controls, to measure data accurately.Although these equipment can utilize the connected mode of exterior fixation bracket to connect, existing exterior fixation bracket stationary fixture cannot meet the installation requirement of these equipment.
Summary of the invention
For solving above-mentioned technical deficiency, the invention provides a kind of can the extenal fixation fixture of multidirectional adjustment, this extenal fixation fixture can multiple directions regulate by the relative angle of its syndeton and distance, connected equipment can be adjusted to the position and angle that meet equipment mounting condition, and not by the impact of exterior fixation bracket screw position change, for orthopedist provides one fixing device easily.The technical scheme that the present invention solves is: a kind of can the extenal fixation fixture of multidirectional adjustment, be provided with the screw fixation clamp (1) of band Camlock switch (2) and the universal ball end (4) of band knob locking switch (5), and the adjutage (3) of band expansion type locking switch (6), it is characterized in that screw fixation clamp (1) and universal ball end (4) can distinguish firm attachment screw and external fixer connecting rod, by Camlock switch (2), band knob locking switch (5) and expansion type locking switch (6) multidirectional adjustment, realize the relative angle of both external fixer connecting rods that multidirectional change is fixed on the screw in screw fixation clamp (1) and is connected to universal ball end (4), and by regulating the distance of both length adjustment of adjutage (3).
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
The present invention is specifically described by embodiment below in conjunction with accompanying drawing.
Detailed description of the invention
Can the extenal fixation fixture of multidirectional adjustment, be provided with the screw fixation clamp 1 of band Camlock switch 2 and the universal ball end 4 of band knob locking switch 5, and the adjutage 3 of band expansion type locking switch 6, it is characterized in that screw fixation clamp 1 and universal ball end 4 can distinguish firm attachment screw and external fixer connecting rod, by Camlock switch 2, band knob locking switch 5 and the multidirectional adjustment of expansion type locking switch 6, realize the relative angle of both external fixer connecting rods that multidirectional change is fixed on the screw in screw fixation clamp 1 and is connected to universal ball end 4, and by regulating the distance of both length adjustment of adjutage 3.Utilization can multiple directions regulate by the relative angle of its syndeton and distance, connected equipment can be adjusted to the position and angle that meet equipment mounting condition, and not by the impact of exterior fixation bracket screw position change.
The present invention has and can be adjusted to exterior fixation bracket connection device the position and angle that meet equipment mounting condition, and by exterior fixation bracket screw position change impact, its have structure simple, easy to operate, measure the advantages such as accurate.
