Abstract
The utility model discloses a portable type fracture repositor which is characterized by comprising two sets of needle clamps (1) which are symmetric left and right and connected sequentially, a needle clamp ball head connection rod (2), a ball head fixator (3), a ball head connection rod (4), an axial telescopic microspur regulator thread sleeved connection (5), a right angle connection sleeved rod (6) and axial telescopic regulator thread sleeved connection (7) which connect two sets of devices together. The portable type fracture repositor achieves three-dimensional rotating reset for fracture, and is small in whole size and convenient to carry. The patient does not need a large-wound operation, two sides of the fracture are fixed through simple steel needles, then through splicing and composition of the fracture repositor and with the aid of mechanical force, the patient can conduct reset, and the fracture can keep fixes state, and the portable type fracture repositor provides good operation environment for next steel plate or intramedullary needle fixing or outer fixing. The portable type fracture repositor is suitable for reset fixing of multiple fractures, such as thighbone fracture, shin bone fracture, splinter bone fracture, ulna fracture, radius fracture and humerus fracture.
Description
Technical field
This utility model relates to medical apparatus and instruments, is a kind of portable fracture reposition instrument specifically.
Background technology
Mainly be manual reset for resetting of fracture at present, or by large-scale extension table.To muscular patient, pure artificial reduction by traction is often very difficult, need to do more muscle and separate, and fracture site is peeled off too much, impact union of fracture in the future.And behind the manual reset, reset effect is kept very poor, is easy to again be shifted once loosing one's grip, and is unfavorable for the placement of internal fixation apparatus, causes operation technique complicated, weak effect.Large-scale extension table apparatus expensive, reset effect is general, often only has the axial traction effect of a direction, narrow application range.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of volume small and exquisite, easy and simple to handle, can sterilize, assembled, omnipotent fracture reposition instrument is for fixing operation inside and outside the fracture of ultimate treatment provides stable operating environment, save operating time, reduce or do not need the wound exposure of fracture, the real minimally-invasive treatment of realizing fracture, accelerating union of bone fracture.
Described portable fracture reposition instrument, it is characterized in that: comprise that pin folder, pin folder bulb connecting rod, bulb holder, bulb connecting rod, the socket of axial stretching microspur actuator screw thread, the right angle of connection connect loop bar, and the axial stretching actuator screw thread that two covering devices connect together is socketed symmetrical each cover successively.
One of described pin folder bulb connecting rod and bulb connecting rod is spherical, and one of its sphere is embedded in the bulb holder.
The other end of described bulb connecting rod is as a movable end of axial stretching microspur actuator screw thread socket, the other end thread bush of described axial stretching microspur actuator screw thread socket is connected to the port that the right angle connects loop bar, and two right angles connect loop bar as two movable ends of same axial stretching actuator screw thread socket.
The other end of described pin folder bulb connecting rod and the middle part of pin folder are fixed.
This utility model has rationally used the pin folder and has had multiaxis to the bulb holder of regulatory function, and carries out in vertical direction the three external threadings socket that axial stretching is regulated, and realizes the three-dimensional rotation of fracture is resetted.Its overall volume is small and exquisite, be easy to carry, and need not large wound operation, only imposing simple draw point in the both sides of fracture fixes, splicing by this utility model positor is compound, reset and can keep stationary state by mechanical force, for next step steel plate or intramedullary needle are fixed, or fixedly provide good operating environment outward.Be suitable for femur, tibia, fibula, resetting of the multiple fracture such as ulna, radius, humerus is fixing.
Description of drawings
Fig. 1 is this utility model structural representation,
Fig. 2 is this utility model user mode sketch map.
Among the figure: 1-pin folder, 2-pin folder bulb connecting rod, 3-bulb holder, 4-bulb connecting rod, the socket of 5-axial stretching microspur actuator screw thread, 6-right angle connects loop bar, the socket of 7-axial stretching actuator screw thread, 8-knochenbruch.
The specific embodiment
The present invention is further described below in conjunction with accompanying drawing: described portable fracture reposition instrument as shown in fig. 1, comprise that pin folder 1, pin folder bulb connecting rod 2, bulb holder 3, bulb connecting rod 4, axial stretching microspur actuator screw thread socket 5, the right angle of connection connect loop bar 6, and the axial stretching actuator screw thread that two covering devices connect together is socketed 7 symmetrical each cover successively.
One of described pin folder bulb connecting rod 2 and bulb connecting rod 4 is spherical, and one of its sphere is embedded in the bulb holder 3.The other end of described bulb connecting rod 4 is as a movable end of axial stretching microspur actuator screw thread socket 5, the other end thread bush of described axial stretching microspur actuator screw thread socket 5 is connected to the port that the right angle connects loop bar 6, and two right angles connect loop bar 6 as two movable ends of same axial stretching actuator screw thread socket 7.The other end of described pin folder bulb connecting rod 2 and the middle part of pin folder 1 are fixed.
Fig. 2 is this utility model user mode sketch map, before not having fixation of bone fragments 8, connection between each parts of the present utility model is movable, can universal rotational between the pin at bulb holder 3 two ends folder bulb connecting rod 2 and bulb connecting rod 4 and the bulb holder 3, the socket 5 of axial stretching microspur actuator screw thread and axial stretching actuator screw thread are socketed 7 also can dismountable.Implement about this fracture reposition instrument is divided into before the fixation two sections, link to each other by axial stretching actuator screw thread socket 7.
During use, need not to perform the operation at fracture.Only need in the sclerotin of fracture both sides, to insert draw point access pin folder, then assembly and connection resetting means.Locking pin folder 1 and bulb holder 3.Then turning cylinder is to expansion and cotraction regulator screw thread socket 7, strut fracture site (because muscle contraction, this step needs most strength, this device reaches by mechanical torsion and keeps), after fluoroscopy during operation struts, result according to positive side position perspective, by axial stretching microspur actuator screw thread socket 5 make fracture near-end and far-end on positive bit slice on an axis, then by unclamping successively the bulb holder 3 of nearly folding end, nearly folding end is promoted, press or rotary manipulation, unclamp the bulb holder 3 of folding end far away, folding end far away is promoted, press or rotary manipulation, make fracture two ends anatomical reduction.If really be difficult to reset, can cut an osculum at fracture, extract the soft tissue that down is pressed in the broken ends of fractured bone out, direct-view is lower observes reseting procedure and effect, can reduce perspective and operating time.Lock all fixtures, keep fixed effect.Fixing for changing in steel plate and the intramedullary needle, or draw point fixedly provides stable operating environment outward, in case dismountable resetting means is finished in interior or outer fixing operation.
