Abstract
The utility model relates to a fixing device after the pelvic fracture is reset, composed of a beam and two connecting blocks. The vertical and horizontal parts of the beam are respectively arranged in the middle holes of the connecting blocks and are controlled by inclined chains, and the front and back parts of the vertical part are respectively processed with aiming holes. One side of the connecting block of the horizontal part is processed with a target hole, and the far end of a taper key is processed with a target hole. The horizontal part of the beam is processed with a groove, the near end of the taper key is processed with a screw, and the horizontal taper key is fixed through the groove by a screw.
Description
This utility model belongs to a kind of operating theater instruments, fixed apparatus after specifically a kind of fracture of pelvis resets.
The fracture of pelvis fixation device that uses is that pelvis steel plate and Kirschner wire, bone bolt are directly fixed at present, up to the present, there is not both at home and abroad the thread a needle apparatus of fault of prevention, its above-mentioned apparatus weak point: 1. pelvis steel plate, because of pelvic anatomy characteristics sclerotin is thin, nail is easily transferred to; Unstable; Pelvis stress is big, flexible deformation; The exposure wound surface is big, and amount of bleeding is big, especially exposes pelvic cavity, and amount of bleeding is many.2. Kirschner wire, bone bolt because of cortex is thin, are difficult for accurately penetrating easy damaged blood vessel, nerve and abdominal organs.
The purpose of this utility model is to overcome above-mentioned deficiency, and utilize tetragon principle and 2 one by one line principle design a kind of simple in structure, easy to operate, do not expose pelvic cavity and the little damage of otch light, go out insufficiency of blood, be convenient to accurately fixedly a kind of fixed apparatus of fracture of pelvis.
This utility model is to realize like this.It is made of a beam and two contiguous blocks, its technical essential is: the vertical and level of beam is partly respectively by in the mesopore of contiguous block, sight hole of vertical part contiguous block the place ahead processing of beam, multidirectional sight hole of rear processing, taper key of processing can slide up and down along the vertical part of beam in the contiguous block.The level of beam is groove of center processing partly, the screwed hole in the one side processing rake hole of contiguous block and restriction rake hole, fix by screw, taper key of processing in the contiguous block, screwed hole of taper key near-end processing, screw is fixed in the taper key screwed hole by the beam groove, in order to axially-movable, and a rake of taper key far-end processing hole.So just constituted this multidirectional pelvis sight, its use principle is: the principle of utilizing tetragon and two one lines, as long as wear one piece of Kirschner wire in fracture far-end utilization rake hole, wear one piece of Kirschner wire by sight hole at the fracture near-end again, just can accurately penetrate the fixing nearly far-end of pulp cavity, mobile contiguous block can be worn many pieces of pins, to reach stable fracture.Because of true pelvis in the form of a ring, can utilize taper key axially-movable rake hole fixed point as multiple fracture, the multidirectional sight hole of reuse is threaded a needle; Fix, take off sight, just finished whole fixation procedure.
Since this utility model adopted tetragon and two one line principles use fixing accurately, safety, convenience, not damaged nervus vasculairs, i.e. pelvic organs official's worry, and otch is little, does not expose pelvic cavity and goes out insufficiency of blood etc., is mainly used in pelvis fracture operation.
Fig. 1 is a structure principle chart of the present utility model.
Below in conjunction with accompanying drawing this utility model is described in detail: beam (1) is that the vertical part (2) of beam is installed in the mesopore (4) of contiguous block (3), a front end processing sight hole (5) of contiguous block (3), can wear Kirschner wire (6), a rear end processing multidirectional rotary body (7) of contiguous block (3), it is rotary body (a 7) upper end processing sight hole (8), can wear Kirschner wire (9), a processing taper key (10) can slide up and down and control along the vertical part (2) of beam in the mesopore (4).The level of beam partly (1) is installed in the mesopore (13) of contiguous block (12), the screwed hole (15) in the one side processing rake hole (14) of contiguous block (12) and a restriction rake hole, fix the rake interior Kirschner wire in hole (14) (17) by screw (16) by screwed hole (15), the level of beam is (11) center processing groove (18) partly, a processing taper key (19) in the mesopore (13) of contiguous block (12), a near-end processing screwed hole (20) of taper key (19), be fixed in the screwed hole (20) rake of the front end of taper key (19) processing hole (22) by groove (18) by screw (21).
Claims (1)
1. multidirectional fracture of pelvis sight, constitute by a beam and two contiguous blocks, its architectural feature is: the vertical part (2) that process a beam (1) beam is installed in the mesopore (4) of contiguous block (3), a front end processing sight hole (5) of contiguous block (3), can wear Kirschner wire (6), a rear end processing multidirectional rotary body (7) of contiguous block (3), promptly a upper end sight hole of processing (8) can be worn Kirschner wire (9), a taper key of processing (10) can slide up and down and control along the vertical part (2) of beam in the mesopore (4), the level of beam partly (11) is installed in the mesopore (13) of contiguous block (12), the screwed hole (15) in the one side processing rake hole (14) of contiguous block (12) and a restriction rake hole, by screw (16) fixation Kel's needle (17), the level of beam is (11) center processing groove (18) partly, a processing taper key (19) in the mesopore (13) of contiguous block (12), a near-end processing screwed hole (20) of taper key (19), be fixed in the screwed hole (20) rake of the front end of taper key (19) processing hole (22) by groove (18) by screw (21).
