Abstract
The utility model belongs to the technical field of medical devices, and particularly provides a sternoclavicular hook bone plate with a hook structure. The sternoclavicular hook bone plate with the hook structure is characterized in that according to shape features of a sternoclavicular joint of a human body, a steel plate is designed to be of a curve-shaped three-segment structure, wherein one segment of the steel plate is of the hook structure, and a cross section of the segment is circular; the other end of the steel plate is of a flat structure; a middle segment is an arc-shaped transition segment; and the hook structure and the flat structure are not in the same plane. According to the sternoclavicular hook bone plate with the hook structure, the hook structure is in the shape of an 'L', the flat structure is slightly curved, the radian of the flat structure is matched with the arc shape of the front side of the segment close to a clavicle of the human body, and a locking hole is formed in the steel plate and used for being fixedly with a screw. By means of the sternoclavicular hook bone plate with the hook structure, not only can the sternoclavicular joint which is dislocated be fully recovered, but also the injured sternoclavicular joint can move slightly in a physiological movement range after the reduction of the sternoclavicular joint. The sternoclavicular hook bone plate with the hook structure has the advantages of being reasonable in structure, simple and safe in surgery, good in postoperative recovery effect and the like.
Description
Technical field
This utility model belongs to medical mechanical domain, specifically is a kind of breast latch hook blade plate with the crotch structure.
Background technology
Sternoclavicular joint is the unique joint between upper limb and the trunk, is made of the sternal end of clavicle and clavicular notch and the 1st costicartilage of breastbone, belongs to sellar joint.The sternoclavicular joint fracture dislocation is common clinical, the sternoclavicular joint fracture dislocation causes serious consequence sometimes, as the symptom of the difficulty of handling up, hoarseness, pneumothorax, dyspnea, brachia plexus injury and relevant blood vessel aspect, long term complication also has the related symptoms of breathing effort, blood vessel pressurized, brachial plexus pressurized, even causes thoracic outlet syndrome, septicemia even death etc.Because breastbone is spongy bone, and clavicle is positioned at the preceding outside of sternoclavicular joint, present Kirschner wire inner fixed law commonly used, steel plate screw can't be fixed effectively at breastbone, and postoperative resets fixing very difficult, often because of the fixing not firm dislocation that produces again, and the repeated multiple times reduction causes more poly-injury, easily produces not conform to and malunion, local deformity, pain is obvious, the sternoclavicular joint normal relation changes, and with the passing of time traumatic arthritis can occur, and part patient the armpit nerve compression too tightly occurs because fixing, local dermatitis, diabrosis, infect, the outer set time is long, and the patient suffering is big, and is big to the daily life influence.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of healing and the ligament repair that can accelerate after the sternoclavicular joint fracture dislocation is provided, thereby early recovers the breast latch hook blade plate of the band crotch structure evident in efficacy of function of joint.
The technical scheme that this utility model adopts is:
A kind of breast latch hook blade plate with the crotch structure, it is characterized in that: according to human body sternoclavicular joint features of shape, steel plate is designed to the indentation three-stage structure, one section is hooked shape structure, and the cross section is circular, and the other end is the flat structure, middle one section arc-shaped transition, hooked shape structure and flat structure are provided with lock hole at steel plate not at grade, are used for screw and fix; Hooked shape structure of the present utility model is L-shaped, and the flat structure is slightly curved, and the nearly section of its radian and clavicle front side arc adapts.
When this utility model used, in the bone hole that breastbone gets out, the other end of crotch was bent to breast clavicle joint the place ahead and is connected with the flat structure insertion of the head crotch pile warp breastbone rear of hooked shape structure from the breastbone rear end in advance.
The state characteristics that this utility model is connected with the both sides clavicle according to the human body breastbone, steel plate is designed to indentation, the steel plate crotch probes into and hooks breastbone after breastbone inserts, the steel plate body then places the subsides of clavicle leading edge to obey in the nearly section of clavicle front side, utilize stopping with SC definite fixing of breastbone cortical bone, to guarantee union of fracture and ligament repair, early recover function of joint, avoid serious postoperative complication.This utility model can not only make the sternoclavicular joint of dislocation be returned to one's perfect health, and make the damage joint can fine motion in the physiological activity scope after resetting.The utlity model has rational in infrastructure, simple, the safety of operation, characteristics such as post-operative recovery is good.

The specific embodiment
Embodiment as shown in Figure 1 and Figure 2, a kind of breast latch hook blade plate with the crotch structure, it is characterized in that: according to human body sternoclavicular joint features of shape, steel plate is designed to the indentation three-stage structure, one section is hooked shape structure 1, and the cross section is circular, and the other end is flat structure 2, middle one section arc 3 transition, hooked shape structure 1 and flat structure 2 are not at grade; Hooked shape structure of the present utility model 1 is L-shaped, and flat structure 2 is slightly curved, and the nearly section of its a radian and clavicle front side arc adapts, and is provided with lock hole 4 at steel plate, is used for screw and fixes.
As shown in Figure 3, lock hole 4 of the present utility model is combined by spherical counterbore 5 and taper thread hole 6, and the cone angle in taper thread hole is 0-30 °.
Be illustrated in figure 4 as another embodiment of the present utility model, the breast latch hook blade plate of the band crotch structure of above-mentioned treatment dislocation of sternoclavicular joint directly arranges external screw thread 7 and pad 8 at the crotch front end, and nut 9 cooperates, and crotch is locked on the breastbone.
Be illustrated in figure 5 as another embodiment of the present utility model, the breast latch hook blade plate of the band crotch structure for the treatment of sternoclavicular joint fracture dislocation as described in Figure 4, connect a connecting rod 10 from flat structure 2, connecting rod 10 two ends respectively are provided with through hole, wherein the external screw thread 7 usefulness nuts 9 of a through hole and crotch front end are fixing, the structural lock hole of another through hole and flat 4 is corresponding, is fixed on the clavicle by screw 11, prevents the sternoclavicular joint backward dislocation.
