Description
Technical field
This utility model relates to the technical field of operating theater instruments, refers in particular to the capital three-jaw of a kind of tractive and embraces pincers.
Background technology
?traumatic hip is dislocated, often with: 1. the avulsion of round ligament of femur and part femur skull block tear out, the 2. comminuted fracture of the rear wall bone block that acetabular bone wall is common, 3. the tearing of acetabular labrum.To the patient meeting open reduction indication, normal need perform the operation in clear up acetabular bone, report is gone through years of suffering and hardship and is cleared up the cracked broken bone block that cannot fix in acetabular bone, the acetabular labrum fringe block resetted is stopped in round ligament of femur, the attachment capital broken bone block of disengaging and outstanding acetabular bone that excision is residual long, in case in the future serious traumatic arthritis and the outer ectopic ossification of hip joint, recover the function of hip joint as far as possible.Because of femoral head be impacted after sclerotin injury serious, blood fortune is poor.Retain the surrounding tissue supporting femoral head blood fortune in art as far as possible, too much should not destroy muscle group and the joint capsule of surrounding.This to cause in art between femoral head and acetabular bone an only residual arc fenestella, although the sick limb of continuous traction in art, because of femoral head cannot directly tractive, appear, confession is detected and clears up acetabular bone.Adopt hamulus of hamate bone to hook neck of femur in art, but hamulus of hamate bone is as limb long tubular bone, for appearing and resetting in art, only has half arcuate structure, easily deviate from when tractive, and firmly excessive in art, easily cause the damage of neck of femur.At present, there is no special apparatus and be applicable to capital anatomic form, and can not firmly draw, to meet the needs appeared in art.
Summary of the invention
The purpose of this utility model is overcome weak point of the prior art and provide the capital three-jaw of a kind of tractive to embrace pincers, and stability when it ensures tractive femoral head in art, can avoid the visual field blocking operator, during to prevent tractive femoral head, loosens and breaks off relations.
For achieving the above object, this utility model adopts following technical scheme:
The capital three-jaw of a kind of tractive embraces pincers, it comprises the first lever and the second lever that are hinged, this first lever and the second lever are by grip part and operating portion composition, be connected by a compression handle between described first lever and the grip part of the second lever, the operating portion of the first lever is provided with a claw-like unit, the operating portion of the second lever is provided with two claw-like unit, respectively this claw-like cell end is equipped with the fixed teeth of resected femur neck in Rhizoma Atractylodis Macrocephalae, the first lever is relative with the second lever fold time, the obvolvent of each claw-like unit phase.
Wherein, the grip part of described first lever and the second lever is long arc shape wide and flat shape, and the position arranging compression handle at the first lever and the second lever is provided with circular hole, and the size of each circular hole is consistent.
Wherein, the degree of tightness product that described compression handle is provided with externally threaded connecting rod by a surface and is located at connecting rod one end forms.
Wherein, the claw-like unit on described each operating portion is all in flat arc, and each claw-like unit mutual obvolvent ovalize structure, and the spacing of each claw-like unit is consistent, respectively the fixed teeth of this claw-like unit extends towards center, and each little fixed teeth is taper.
The beneficial effects of the utility model are: its in operating portion be the claw-like Unit Design of flat arc, when each claw-like unit obvolvent, oval femoral head can be clamped by each claw-like unit simultaneously, by the pointed fixed teeth of claw-like unit, resected femur neck, ensures stability during tractive femoral head in art; The design of long arc shape wide flat grip part, can avoid the visual field blocking operator, and by compression handle locking spinner helicoid on grip part, maintains the clamping degree between two handles, during to prevent tractive femoral head, loosens and breaks off relations.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail:
As shown in Figure 1, this utility model embraces pincers about the capital three-jaw of a kind of tractive, and it comprises the first lever 1 and the second lever 2 be hinged, and this first lever 1 and the second lever 2 form by grip part a and operating portion b.
Be connected by a compression handle 3 between first lever 1 and the grip part a of the second lever 2, the operating portion b of the first lever 1 is provided with a claw-like unit c, the operating portion b of the second lever 2 is provided with two claw-like unit c, respectively this claw-like unit c end is equipped with the fixed teeth d of resected femur neck in Rhizoma Atractylodis Macrocephalae, the first lever 1 is relative with the second lever 2 fold time, the obvolvent of each claw-like unit c phase, can clamp oval femoral head.
Wherein, the grip part a of the first lever 1 and the second lever 2 is long arc shape wide and flat shape, the position arranging compression handle 3 at the first lever 1 and the second lever 2 is provided with circular hole, the size of each circular hole is consistent, curved the first flat lever 1 and the second lever 2 of long arc shape, can avoid the visual field of block resistance patient.
Further, the degree of tightness product 32 that compression handle 3 is provided with externally threaded connecting rod 31 by a surface and is located at connecting rod 31 one end forms, adjusted by degree of tightness product 32 and maintain the clamping degree between the first lever 1 and the second lever 2, during to prevent tractive femoral head, loosening and break off relations.
Again further, claw-like unit c on each operating portion b all in flat arc, each claw-like unit c mutual obvolvent ovalize structure, respectively this claw-like unit c is without corner angle, and the spacing of each claw-like unit c is consistent, respectively the fixed teeth d of this claw-like unit c extends towards center, and each little fixed teeth d is the taper of outstanding 0.3cm, by changing fixed teeth d resected femur neck, ensure stability during traction, because claw-like unit c circular arc is smooth, when folder draws, minimum level is reduced to the cartilage injury of femoral head surfaces.
The above is only to preferred embodiment of the present utility model; not scope of the present utility model is limited; therefore under the prerequisite not departing from this utility model design spirit; the equivalence change that the common engineers and technicians in this area do structure described in the utility model, feature and principle or decoration, all should fall in protection domain that this utility model applies for a patent.
