Abstract
A kind of NiTi memorial alloy encircling type prosthese rib, belongs to Medical orthopedic instrument field.Including crossbeam, the both ends of described crossbeam arrange and encircle arm, and described crossbeam two ends arrange end tooth.The shortcoming that this utility model prosthese rib overcomes traditional treatment, simple to operate, fixed, it is substantially reduced operating difficulty, unique " memory " function, lasting self-pressurization is formed under normal body temperature, provide good mechanics to ensure, the integrity of thorax can be recovered, maintain the seriality of rib, enable lung tissue well to expand, improve pulmonary ventilation, prevent chest wall malacia and paradoxical breathing；Simultaneously can the stable fracture broken ends of fractured bone, it is to avoid the damage to intrathoracic internal organs again of the rib broken ends of fractured bone；Also can prevent the outside angulation deformity of the rib broken ends of fractured bone, reduce the neuralgic incidence rate of rib, effectively alleviate pain in patient chest, shorten the hospital stays, recovered labour force to greatest extent.Use NiTi memorial alloy medical embedded material biocompatibility good, more after without taking out.
Description
Technical field
This utility model belongs to Medical orthopedic instrument field, relates to a kind of NiTi memorial alloy encircling type prosthese rib.
Background technology
In recent years, the rib damage caused due to disease, traffic accident and traumatic injury is more and more, and a lot for the treatment of meanss are reached by cut-out rib.Fracture of rib is most commonly seen in passivity thoracic trauma, and fracture of multiple ribs is the most common, and the flail chest (paradoxical breathing) caused by the most many places fractures of rib is the main cause of thoracic trauma Deaths.At many lists, fracture of rib typically will not cause serious breathing and disturbance of circulation；But many many places fractures of rib can cause paradoxical breathing, chest wall malacia, and often merges visceral organ injury in thorax abdomen, mainly to maintain ventilation and fixing thoracic wall, corrects and breathes and disturbance of circulation.Now, available fascia lata (autologous, allosome, calf fascia) is repaired.But, processing intrathoracic visceral organ injury in time and many many places ribs are excised by correction besoin de respirer simultaneously, this is accomplished by being fixed the rib broken ends of fractured bone.Traditional metal internal fixation operation operation complexity, thorax poor stability, the rib broken ends of fractured bone easily misplaces and damages the nerve on side, blood vessel, permanent thorax can be stayed to cave in, deformity and other sequela after healing.
Utility model content
Technical problem to be solved in the utility model be provide for shortcoming of the prior art a kind of have simple to operate, fixed, be substantially reduced operating difficulty, avoid respiratory movement to cause the NiTi memorial alloy encircling type prosthese rib of the advantages such as later stage fixture comes off.
Adopt the following technical scheme that for solving technical problem of the present utility model
A kind of NiTi memorial alloy encircling type prosthese rib, including crossbeam, the both ends of described crossbeam arrange and encircle arm, and described crossbeam two ends arrange end tooth.
Described crossbeam both sides arrange reinforcement.
Described reinforcement undulate or rectangle.
Hollow out in the middle of described crossbeam.
A kind of NiTi memorial alloy encircling type prosthese rib, including crossbeam, described crossbeam one end arranges and encircles arm, described in encircle the crossbeam end outside arm end tooth be set, the other end of described crossbeam arranges hook.
Described crossbeam both sides arrange reinforcement.
Described reinforcement undulate or rectangle.
Hollow out in the middle of described crossbeam.
The shortcoming that this utility model NiTi memorial alloy prosthese rib overcomes traditional treatment, simple to operate, fixed, it is substantially reduced operating difficulty, unique " memory " function, lasting self-pressurization is formed under normal body temperature, provide good mechanics to ensure, the integrity of thorax can be recovered, maintain the seriality of rib, enable lung tissue well to expand, improve pulmonary ventilation, prevent chest wall malacia and paradoxical breathing；Simultaneously can the stable fracture broken ends of fractured bone, it is to avoid the damage to intrathoracic internal organs again of the rib broken ends of fractured bone；Also can prevent the outside angulation deformity of the rib broken ends of fractured bone, reduce the neuralgic incidence rate of rib, effectively alleviate pain in patient chest, shorten the hospital stays, recovered labour force to greatest extent.Use NiTi memorial alloy medical embedded material biocompatibility good, more after without taking out.May be manufactured without same model specification and adapt to different patients.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail:
As shown in Figure 1, 2, 3, a kind of NiTi memorial alloy encircling type prosthese rib, including crossbeam 2, crossbeam 2 instead of the rib that human body is cut, can support thoracic wall and recover the original form of thorax.Arranging at the both ends of crossbeam 2 and encircle arm 1, arrange end tooth 3 at crossbeam 2 two ends encircled outside arm 1, end tooth 3 is in order to strengthen the hold of prosthese rib and bone.Crossbeam 2 both sides can arrange reinforcement 4, and reinforcement 4 protects crossbeam 2, in order to preferably replace the cut rib of human body.Reinforcement 4 can become the reinforcement 4 of undulate or rectangle, waveform or rectangle to make NiTi memorial alloy prosthese rib be more closely similar to the people's osteoarthrosis connected, beneficially deformation.In the middle of crossbeam 2 can engraved structure, engraved structure is to reduce consumptive material, alleviating weight, expose the visual field, it is ensured that the mechanical property of adapter and human body rib closer to, to such an extent as to by external impacts when, be not result in secondary fracture.
As shown in Figure 4, a kind of NiTi memorial alloy encircling type prosthese rib, including crossbeam 2, arrange in crossbeam 2 one end and encircle arm 1, encircle crossbeam 2 end outside arm 1 and end tooth 3 is set, end tooth 3 is the hold in order to strengthen prosthese rib and bone.The other end at crossbeam 2 arranges hook 5.The NiTi memorial alloy prosthese rib of this structure is primarily adapted for use in the rib reseclion operation of costa sternales junction.When implanting NiTi memorial alloy prosthese rib, the hook 5 of afterbody hooks on breastbone, secures the position of NiTi memorial alloy prosthese rib, prevents prosthese rib play.Crossbeam 2 both sides can arrange the reinforcement 4 of waveform or rectangle, and reinforcement 4 protects crossbeam 2, in order to preferably replace the cut rib of human body, makes NiTi memorial alloy prosthese rib be more closely similar to the people's osteoarthrosis connected, beneficially deformation.Can be engraved structure in the middle of crossbeam 2.Engraved structure in the middle of crossbeam 2 is to reduce consumptive material, alleviating weight, expose the visual field, it is ensured that the mechanical property of adapter and human body rib closer to, to such an extent as to by external impacts when, be not result in secondary fracture.
The Main Function encircling arm of all above NiTi memorial alloy prosthese rib is that the rib broken ends of fractured bone with both sides is connected, in order to fixing adapter, and depending on the length of intermediate transverse girder can be according to the length of excised rib, encircle arm crossbeam and combination define the length of NiTi memorial alloy prosthese rib.Wherein, the logarithm encircling arm can determine according to the length of the rib broken ends of fractured bone, the dynamics of encircling.NiTi memorial alloy prosthese rib is before implantation, by 0-5 DEG C of sterile saline cold compress, arm is encircled with what medical distraction forcep strutted NiTi memorial alloy prosthese rib during implantation, then carry out excising the replacement of rib, encircle arm embrace in excision after patient rib on, crossbeam replaces cut rib, reliable and stable, easy to operate.
