Abstract
An olecranon type ulna fixation frame includes olecranon hooks, an adjusting nut, a handle, a fixation block, a worm needle and a fixation bolt. The olecranon hooks with a cylinder middle-rear part and worms on their rod are two paralleled metal hooks. The adjusting nut for adjusting tightness degree of the olecranon hooks is disposed between the olecranon hooks and the handle. A screw with inner threads is disposed on the front terminal of the handle and is connected with the worm axis on the middle-rear part of the olecranon hooks. A gimbal is disposed at the rear terminal of the screw. An inner hollow ring cooperating with the gimbal is disposed on the front terminal of the fixation block. The fixation bolt for fixing the gimbal is disposed behind the inner hollow ring. A local anaesthesia can be applied when using the disclosed fixation frame for treating fracture. Manual reposition can be used, and the operation is simple with little trauma and low cost. Olecranon fracture can be fixed effectively, so that early function exercise can be carried out to reduce joint ankylosis and traumatic arthritis.
Description
Technical field:
This utility model relates to the fracture operation fixture, relates in particular to a kind of olecranon formula ulna fixed mount.
Background technology:
Olecranal fracture is concurrent estranged when displacement, and expectant treatment adopts plintlet and plaster bandage to make external fixation, can not overcome the tractive of triceps brachii to the fracture near-end, takes place to be difficult to anatomical reduction after the fracture; And open reduction adopts " 8 " word steel wire, intramedullary needle, Kirschner wire or olecroanon claw type steel plate, comprise the various fixed method that Chinese patent ZL88202010.2 is related, though can reach anatomical reduction, but wound is big, the expense height, also to perform the operation once more after the union of fracture, take out inside-fixture, increase patient's misery.Chinese patent ZL87232205 discloses a kind of " olecranal fracture pressurization external fixator ", can exempt second operation to the fracture pressurization that resets, but that overall structure is installed and unloaded is complicated, and adjustability is poor, uses still not ideal enough.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of olecranon formula ulna fixed mount is provided, and can make the reduction of the fracture, and second operation is exempted in fixation, and wound is little, and is easy to use.
Olecranon formula ulna fixed mount described in the utility model, including olecranon hook, adjusting nut, handle, fixed block, screw needle and set bolt forms, said olecranon hook, be two metal hooks that are claw type arranged side by side, the tip of hook first three/place is prismatic, can be used for thrusting the fracture near-end.The postmedian of olecranon hook is cylindrical, and the bar portion of olecranon hook is provided with screw thread, with the screw-internal thread fit of handle.Bar portion at the olecranon hook is provided with the adjusting nut that is used to regulate olecranon hook degree of tightness, when using olecranon formula ulna fixed mount described in the utility model, adjusting nut should be tightened, to prevent the rotary moveable between olecranon hook and the handle.Handle is the main body connector of olecranon formula ulna fixed mount described in the utility model, and said handle is cylindric, and the front end of handle is provided with the screwed hole of inner mantle fiber, and screwed hole is connected with the postmedian thread spindle of described olecranon hook.The rear end is provided with the spherical universal joint that is that is connected with described fixed block, and the front end of fixed block is provided with the interior empty circle that matches with the spheroidal universal joint, and the position after the interior empty circle of fixed block leans on is provided with the set bolt that permanent universal joint is used.Said fixed block includes symmetric two semi-cylindrical assemblies and forms, on said symmetric two assemblies, horizontal and vertically respectively be provided with two through holes, two horizontal through holes are used to penetrate set bolt, two symmetric assemblies are fixed together, and the spheroidal universal joint with handle rear end is stuck in the connection of fixed block front end with within the interior empty circle simultaneously; Vertically two through holes that are provided with are used for and wear fixed two screw needles of bone being installed togather.
When using olecranon formula ulna fixed mount described in the utility model to treat olecranal fracture, can adopt local anesthesia, manual reduction, simple to operate, wound is slight, surgery cost is lower, can be effectively fixing olecranal fracture, make the fracture end pressurization that resets, and can early functional exercise, the moulding mill that helps articular surface is made, and reduces the generation of ankylosis and traumatic arthritis.
Description of drawings:
Accompanying drawing is an olecranon formula ulna fixed rack structure sketch map described in the utility model.1-olecranon hook 2-adjusting nut 3-handle 4-locating piece 5-set bolt 6-screw needle
The specific embodiment:
Referring now to accompanying drawing, be described as follows in conjunction with the embodiments: olecranon formula ulna fixed mount described in the utility model, including olecranon hook 1, adjusting nut 2, handle 3, fixed block 4, set bolt 5 and screw needle 6 forms, said olecranon hook 1, be two metal hooks that are claw type arranged side by side, the tip of hook first three/place is prismatic, can be used for thrusting the fracture near-end.The postmedian of olecranon hook 1 is cylindrical, and the bar portion of olecranon hook 1 is provided with screw thread, with the screw-internal thread fit of handle 3.Bar portion at olecranon hook 1 is provided with the adjusting nut 2 that is used to regulate olecranon hook 1 degree of tightness, when using olecranon formula ulna fixed mount described in the utility model, adjusting nut 2 should be tightened, to prevent the rotary moveable between olecranon hook 1 and the handle 3.Handle 3 is main body connectors of olecranon formula ulna fixed mount described in the utility model, and said handle 3 is cylindric, and the front end of handle 3 is provided with the screwed hole of inner mantle fiber, and screwed hole is connected with the postmedian thread spindle of described olecranon hook 1.The rear end is provided with the spherical universal joint that is that is connected with described fixed block 4, and the front end of fixed block 4 is provided with the interior empty circle that matches with the spheroidal universal joint, and the position after the interior empty circle of fixed block 4 leans on is provided with the set bolt 5 that permanent universal joint is used.Said fixed block 4 includes symmetric two semi-cylindrical assemblies and forms, on said symmetric two assemblies, horizontal and vertically respectively be provided with two through holes, two horizontal through holes are used to penetrate set bolt 5, two symmetric assemblies are fixed together, and the spheroidal universal joint with handle 3 rear ends is stuck in the connection of fixed block 4 front ends with within the interior empty circle simultaneously; Vertically two through holes that are provided with are used for and wear fixed two screw needles 6 of bone being installed togather.When using olecranon formula ulna fixed mount described in the utility model to treat olecranal fracture, can adopt local anesthesia, manual reduction, simple to operate, wound is slight, surgery cost is lower, can be effectively fixing olecranal fracture, make the fracture end pressurization that resets, and can early functional exercise, the moulding mill that helps articular surface is made, and reduces the generation of ankylosis and traumatic arthritis.
