Description
Technical field
This utility model relates to a kind of operating theater instruments, specifically a kind of bone fracture device.
Background technology
Along with people's living standard improves, the birth of the flourish and various vehicles of various sports.Various damages also become the brand-new challenge that orthopedist will face day by day.The fracture recovery ways of appendicular skeleton has two kinds at present, and a kind of is to use external protector (Gypsum Fibrosum, clamping plate and recovery protector), and a kind of is to perform the operation, and uses steel wire binding, and steel plate is fixing etc.External protector is easily subject to the impact of individual factor and external environment, and limited larger.And operative treatment adopts open surgery substantially at present, otch is large, large to muscle and soft tissue injury, and post-operative recovery is slower.
Utility model content
In order to address the above problem, this utility model provides a kind of bone fracture device, when carrying out Minimally Invasive Surgery, can make the skeleton of fracture set back fast, has solved open surgery impaired large, recovery time of the longer problem that adopts.
This utility model is by the following technical solutions: bone fracture device, it is characterized in that, and comprise front end tool and handle, described handle comprises upper handle and lower handle, described upper handle front end and lower handle front end intersect and stack, and are fixed as one by locking locknut; The upper end of the affixed tooth bar in rear end of described upper handle, a side of described tooth bar bottom is provided with the pawl of proper alignment, and described pawl engages with the rear end of lower handle; Described front end tool comprises annulus and positioning table, described annulus front end is provided with gap, described annulus rear end is provided with breach, a side at annulus is provided with steel wire passage, described positioning table comprises positioning table and lower positioning table, the two ends of described upper positioning table connect respectively breach upper end and lower handle front end, and described lower positioning table two ends connect respectively breach lower end and upper handle front end.
Further, described steel wire channel connection breach upper end and breach lower end, and steel wire passage communicates with the external world.
Further, the upper end of described tooth bar is fixed on the rear end of upper handle by rotating shaft.
Further, the rear end of described lower handle is wedge shape.
Further, described annulus front end gap has certain inclination angle.
Further, described upper handle, lower positioning table, the annulus bottom structure that is formed in one, described annulus top, upper positioning table and the lower handle structure that is formed in one.
The beneficial effects of the utility model are: there is the steel wire passage around a circle bone fracture device inside, steel wire is the skeleton around fracture from bone fracture device inner loop easily, and opening operation is young, also little to the damage of muscle and soft tissue, and operation technique is simple, doctor's labor intensity lowers.
Accompanying drawing explanation
Fig. 1 is this utility model perspective view;
Fig. 2 is the main TV structure schematic diagram of this utility model;
Fig. 3 is A-A cross section sectional structure schematic diagram in Fig. 2.
In figure: 1 circular cavity, 2 annulus, 21 gaps, 22 breach, 23 breach upper ends, 24 breach lower ends, 3 steel wire passages, 4 steel wire feeder connections, 5 positioning tables, positioning table on 51,52 times positioning tables, 6 locking nuts, 7 upper handles, 8 tooth bars, 9 pawls, 10 lower handles, 11 rotating shafts.
The specific embodiment
As shown in Figure 1-Figure 3, the bone fracture device of this programme comprises front end tool and handle, and described handle comprises upper handle 7 and lower handle 10, and described upper handle 7 front ends and lower handle 10 front ends intersections stack, and are fixed as one by locking locknut 6, the upper end of the affixed tooth bar 8 of rotating shaft 11 is crossed in the rear end of described upper handle 7, and a side of described tooth bar 8 bottoms is provided with the pawl 9 of proper alignment, and described pawl 9 engages with the wedge shape rear end of lower handle, described front end tool comprises annulus 2 and positioning table 5, described annulus 2 front ends are provided with gap 21, and gap 21 has certain inclination angle (in Fig. 2, angle between gap and bone fracture device central axis is inclination angle, this inclination angle is 30 degree), annulus 2 rear ends are provided with breach 22, described positioning table 5 comprises positioning table 51 and lower positioning table 52, the two ends of described upper positioning table 51 connect respectively breach upper end 23 and lower handle 10 front ends, described lower positioning table 52 two ends connect respectively breach lower end 24 and upper handle 7 front ends, a side at annulus 2 is provided with steel wire passage 3, described steel wire passage 3 is communicated with breach upper end 23 and breach lower end 24, and steel wire passage 3 communicates with the external world.
Concrete while making above-mentioned bone fracture device, described upper handle 7, lower positioning table 52, the annulus 2 bottoms structure that is formed in one, described annulus 2 tops, upper positioning table 51 and lower handle 10 structure that is formed in one.
During operation, first take off locking nut 6, by upper, lower handle separately, now, affixed annulus 3 by gap 21 also in two, and along the bone surface of fracture, pass up and down respectively, the back side at wound contacts, then, utilize locking nut 6 by upper handle, lower handle is integrally connected, by adjusting the contact position of lower handle 10 wedge shape rear ends and pawl 9, make positioning table 51 and lower positioning table 52 closures, again annulus 2 is combined, now, in the circular cavity that annulus 2 encompasses (1), clamp and fix the skeleton of fracture, the steel wire of operation use can pass through the steel wire feeder connection 4 of breach upper end 23, from outside, enter in steel wire passage 3, steel wire interior current one week at steel wire passage 3, from breach lower end 24, pass, tractive steel wire shifts out bone fracture device from steel wire passage 3, contact with the skeleton of fracture, steel wire is tightened in finally binding, locking fixation of bone fragments.
Except structure described in the utility model, all the other are prior art.
The above is preferred implementation of the present utility model; for those skilled in the art; not departing under the prerequisite of this utility model principle, can also make some improvements and modifications, these improvements and modifications are also regarded as protection domain of the present utility model.
