Description
Technical field
The lesser trochanter of femur reduction fixture device belongs to medical instruments field.Be specifically related to a kind of fracture of the lesser trochanter holder.
Background technology
When intertrochanteric fracture, many times all with trochantinian displacement fracture.Biomechanics test according near end of thighbone, the trochantinian damaged near end of thighbone outside of making increases by 60% load, as not fixedly lesser trochanter very easily cause the inefficacy of internal fixation and the displacement of fracture, therefore, during intertrochanteric fracture, resetting of lesser trochanter displacement fracture is fixing extremely important.But in technical operation, owing to do not reset and fixed apparatus the comparison difficulty that lesser trochanter reduction of the fracture fixing operation is become accordingly.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and can reset fast and fix in order to overcome above-mentioned defective, the reduction fixture device of lesser trochanter of femur easily simple to operation.
The technical scheme that its technical problem that solves this utility model adopts is: this lesser trochanter of femur reduction fixture device, it is characterized in that: comprise handle, hunchbacked portion, sleeve and sleeve pipe, the head end of back of a bow portion is the circular orientation hole, back of a bow portion is arranged on a telescopic end, handle is arranged on the telescopic other end, sleeve pipe is movably arranged in the sleeve, and the corresponding side with sleeve pipe in circular orientation hole is provided with annular tooth.
Sleeve pipe comprises handgrip and union body, and union body one end is provided with annular tooth, and handgrip is vertically fixed on the union body other end.
The head end of back of a bow portion can be controlled lesser trochanter of femur, can make the lesser trochanter reduction of the fracture by the handle tractive of exerting oneself, the circular orientation hole can make drill bit and hold-down screw can pass lesser trochanter cortex smoothly, the annular tooth spine can increase controls effect, avoid sliding, the hunchbacked portion of semicircular arc protuberance can comply with arcual surface of bone, make the head end of hunchbacked portion place the offside of sleeve part, hollow bushing is through in the sleeve, by telescopic slip the sleeve pipe front end is supported to bone surface, and drill bit is beaten to offside the aiming effect is arranged during boring by sleeve pipe.Sleeve diameter is bigger after removing sleeve pipe, can make things convenient for the operation of tapping and pedicle screw.
Head end with hunchbacked portion during use places the lesser trochanter of femur surface, by the tractive handle lesser trochanter is resetted, passing sleeve pipe forward supports to surface of bone, by overlapping effective drill bit punching, and the circular orientation hole by hunchbacked size end makes boring see through the lesser trochanter cortical bone, removes behind the sleeve pipe by the sleeve tapping and implants fixedly lesser trochanter of os integumentale screw.
Compared with prior art, the beneficial effect that this utility model had is: lesser trochanter of femur reduction fixture device of the present utility model, head end is controlled lesser trochanter during use, holds the handle Retracting repositioning, and is easily convenient, better reduction.Head end is permitted drill bit for the circular orientation pore volume and screw passes through, can make lesser trochanter effectively controlled smooth pedicle screw under the fixed situation, the slip of sleeve pipe in sleeve is adjustable to the distance of head end, to adapt to different near end of thighbone diameters, drill bit penetrates lesser trochanter cortex smoothly by the circular orientation hole that hollow bushing can aim at head end, removes operations such as tapping after larger-diameter sleeve can conveniently be holed behind the sleeve pipe, pedicle screw.The convenience of this utility model operating theater instruments is simple and direct can obviously to shorten operating time, improves fixed effect, and the reliability of intertrochanteric fracture operative treatment is improved significantly.Filled up the blank of this area.
Description of drawings
Fig. 1 is this utility model lesser trochanter of femur reduction fixture device structural representation.It is most preferred embodiment of the present utility model.
Wherein: 1 handle, 2 sleeve pipes, 3 sleeves, 4 circular orientation holes, 5 hunchbacked portions.
The specific embodiment
Be described further below in conjunction with 1 pair of this utility model lesser trochanter of femur of accompanying drawing reduction fixture device:
With reference to Fig. 1
This lesser trochanter of femur reduction fixture device, form by handle 1, sleeve pipe 2, sleeve 3, circular orientation hole 4, hunchbacked portion 5, handle 1, sleeve pipe 2, sleeve 3 and circular orientation hole 4 are integral structure, back of a bow portion 5 is arranged on an end of sleeve 3, the handle 1 oblique other end that is fixed on sleeve 3 utilizes lever principle firmly convenient.Sleeve pipe 2 is movably arranged in the sleeve 3, and sleeve pipe 2 is made up of handgrip and union body, and union body one end is provided with annular tooth, and handgrip is vertically fixed on the union body other end.Circular orientation hole 4 is arranged on the head end of hunchbacked portion 5, and circular orientation hole 4 is provided with annular tooth with sleeve pipe 2 corresponding sides.
Should be noted that the embodiments described herein only is used to illustrate, be not limited to the present invention.Handle 1, sleeve pipe 2, sleeve 3 and circular orientation hole 4 also can be designed as the split type structure that fits together.The locating hole 4 of the head end of back of a bow portion 5 also can be designed as square or other shapes.As long as can realize function of the present invention.
Operation principle and work process are as follows:
During use hunchbacked portion 5 head ends are placed the lesser trochanter of femur surface, by tractive handle 1 lesser trochanter is resetted, passing sleeve pipe 2 forward supports to surface of bone, punch by sleeve pipe 2 usefulness drill bits, and the circular orientation hole 4 by hunchbacked portion 5 head ends makes boring see through the lesser trochanter cortical bone, removes sleeve pipe 2 backs by sleeve 3 tapping with implant fixedly lesser trochanter of os integumentale screw.
