Abstract
A screw fixation guide for reduction of fractures in orthopaedics comprises a semi-circle arc. Each of two ends of the semi-circle arc is connected fixedly with a casing with an internal thread on the inner wall. Each of the two casings is in thread connection with a guide fixation bolt. The guide fixation bolt has an external thread on the outer wall, has a through hole therein, and is connected with a screw. The external port of the guide fixation bolt is provided with a fixation self-locking open slot. The utility model integrates the optimum fixation point and optimum guide hole point to solve the problem of simultaneous fixation and orientation. Since the screw fixation guide has fixation, guide and retraction functions, the utility model is suitable for open operations and is also suitable for minimally-invasive operations for bone closure, restoration and fixation, with advantages of minimized damage to tissue and reduced operation cost.
Description
Technical field
This utility model relates to the bone surgery set in a kind of medical apparatus and instruments, particularly a kind of spiral fixedly conductor.
Background technology
In the clinical orthopaedics operative reduction process, the often interim fixed position of active homing also be the optimum that needs pilot hole to fixedly secure forever, and traditional fixed apparatus and guider is the both sides of contradiction on these 2, can not take into account mutually.
Summary of the invention
The purpose of this utility model provides the spiral fixedly conductor that a kind of fixing point with the best and best pilot hole point unite two into one.
To achieve these goals, the spiral fixedly conductor of this utility model, comprise: the semicircle bow, semicircle bow semicircular in shape is characterized in that: the two ends of semicircle bow is fixedly connected with sleeve respectively, and telescopic inwall has female thread, be connected with the guide securement bolt respectively by screw thread in two sleeves, the outer wall of guide securement bolt has external screw thread, has through hole in the guide securement bolt, is connected with nut on the guide securement bolt respectively; The external port of guide securement bolt has fixedly self-locking open slot.
The spiral fixedly conductor of this utility model has overcome the weak point of original apparatus, learns from other's strong points to offset one's weaknesses, and fixing point of the best and best pilot hole point are united two into one, and can the two take into account, and satisfactorily resolves the problem of taking into account fixing and guiding.Because that spiral fixedly conductor possesses is fixing, lead and avoid three functions, so it not only is suitable for open surgery, solved the problem that has both of fixing, lead, avoid three big functions, also be applicable to the operation of the fixed Wicresoft of closed reduction, alleviate greatly the wound of tissue is destroyed, also reduce surgery cost, had good clinical utilization benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Among the figure: 1, sleeve; 2, guide securement bolt; 3, nut; 4, semicircle bow; 5, fixing self-locking open slot.
The specific embodiment
This utility model as shown in Figure 1, comprise: semicircle bow 4, semicircle bends 4 semicirculars in shape, the two ends of semicircle bow 4 is fixedly connected with sleeve 1 respectively, the inwall of sleeve 1 has female thread, is connected with guide securement bolt 2 respectively by screw thread in two sleeves 1, and the outer wall of guide securement bolt 2 has external screw thread, have through hole in the guide securement bolt 2, be connected with nut 3 on the guide securement bolt 2 respectively; The external port of guide securement bolt 2 has fixedly self-locking open slot 5 (in addition referring to Fig. 2).
Parts of the present utility model are formed and use principle:
1, semicircle bow: semicircular in shape, its two ends are female sleeves, hold the drill bit of getting just along promptly deciding the path thus, are piercing in the other end of semicircle bow.Function: determine the boring point, portal a little and bore path.
2, guide securement bolt: be threaded outside, interior is hollow stay bolt, be about 8 centimetres, its external port is fixing self-locking open slot, its diameter of bore is 3.2 millimeters, 3.5 millimeter, 4.5 millimeters different model specifications, function: (1) guide function: drill bit can be played guiding and be avoided effect by its hollow passing.(2) fixed function: it can bend the sleeve direction along semicircle and move the other end formation jaw that bends with semicircle, needing fixed position to embed jaw, promptly plays fixation after fixedly the self-locking open slot is tightened.
Because spiral fixedly conductor possesses fixed guide and avoids three functions, so it not only is suitable for open surgery, solved the problem that has both of fixing, lead, avoid three big functions, also be applicable to the operation of the fixed Wicresoft of closed reduction, alleviate greatly the wound of tissue is destroyed, also reduce surgery cost, had good clinical utilization benefit.
In the closed reduction internal fixation operation as fracture of the tibial plateau: after manual reduction is satisfied with under having an X-rayed in conjunction with C type arm x-ray, tibial plateau is embedded the jaw of semicircle bow, inside turn guide securement bolt, behind the skin upper cut of tibial plateau both sides, can tighten the fixedly self-locking open slot of locking guide securement bolt, can be used by two or more spiral fixedly conductors as need are fixing in many ways.Tibial plateau is fixed in reset position, finishes fixed function, hollow through the guide securement bolt again, can known boring point, portal a little and bore path under hole, finish guiding and avoid function, install and fix the bolt internal fixation.
