Description
Technical field
The utility model belongs to medical surgical instrument technical field, is related to a kind of shoulder joint mirror cavitas glenoidalis bone defective bone
Block operating theater instruments, and in particular to a kind of adjustable operation locator.
Background technology
Cavitas glenoidalis injury of lip is a kind of common disease, is often caused by habitual dislocation of shoulder.Most of patients, first
It is secondary by movement or after external force causes dislocation, that is, develop into habitual dislocation.Capsular ligament broad-mouthed receptacle for holding liquid repair of lip (Bankart) is shoulder
The fixed the most frequently used modus operandi of joint anterior instability, but for there are the dislocation of the Patients on Recurrence of the serious bony defect of shoulder broad-mouthed receptacle for holding liquid leading edge
Risk is higher.Coracoid displacement Latarjet operations provide solution for this kind of patient, and obtain good effect, especially
It is for young patient.
Minimally invasive surgery is one of cross-centennial high-new surgery technological achievement of clinical medicine circle.Minimally invasive surgery apparatus is represented as
Endoscope.Such as duct using keyhole size or miniature incision, you can carry out the excision of abdominal visceral browser lesion, deformity is entangled
Just, the various surgical operations such as reparation or reconstruction, are finally reached therapeutic purposes.Minimally Invasive Surgery be different from last century surgical operation it
Be in, the former can reduce surgical wound area, avoid significantly the exposing of in-vivo tissue caused by infection, and disease can be made
People faster fully recovers, and shortens hospital stays and medical expense.Minimally Invasive Surgery apparatus can be by internal wound caused by traditional surgery
It is reduced to minimum degree.Therefore, research is thought, micro-wound surgical operation is one " cross-centennial milestone ".Such as arthroscopic surgery
Be major progress of the Minimally Invasive Surgery theory in field of orthopaedics, is the developing direction of joint surgery.It is external from last century 70
Age starts gradually to be applied to clinic, and China has introduced this technology in the eighties.In recent years with the hair of medical knowledge
Exhibition and medical instrument are continuously improved, arthrocsopic surgery with its it is notable the advantages of received by more and more doctors and patient,
Gospel is brought for numerous patients with joint diseases.Grow rapidly by decades, led now applied to the most of of orthopaedics
Domain, especially in terms of shoulder joint mirror and knee arthroscope surgical technic, various new methods are even more to emerge in an endless stream, and are maked rapid progress.
As the open surgery characterized by " major trauma " develops to the Minimally Invasive Surgery direction characterized by " microtrauma ",
The Minimally Invasive Surgery apparatus of new generation towards natural cavity is explored into inexorable trend.A workman must first sharpen his tools if he is to do his work well.In face of life
The demand of medical development is ordered, the principles of science for exploring advanced operating theater instruments innovative design and bionical manufacture is subjects of mechanical engineering weight
Want one of task.Currently, since Minimally Invasive Surgery device design theory does not have fundamental change, cause many complicated delicate procedures without
Method is completed.For a long time, China is insufficient in this direction basic research, constrains the development of Minimally Invasive Surgery technique with the apparatus.Minimally invasive hand
Art apparatus creates the mixing together for being related to the subjects such as machine science, life science and clinical medicine into the scientific basic with manufacture, leads to
The basic theory and technique study of Minimally Invasive Surgery apparatus are crossed, new treatment principle and instrument, correlative study will be provided for clinical medicine
The new of medical technology will be expedited the emergence of to change.
During latarjet operations are carried out, the location difficulty of lower processus coracoideus is intercepted, due to special under no arthroscope
Operating theater instruments be used for processus coracoideus positioning or drilling under mirror, so need open surgery at present, the notch considerable influence of generation
Beauty, and lack the amplification monitoring effect under arthroscope, only by patient's possessed surgical experience in itself, so needing under mirror
Cartilage transplantation special equipment, so as to reduce the wound for patient.
Latarjet operating theater instruments firstly the need of solution is exactly to the fixation problem of processus coracoideus under arthroscope, due to mesh at present
Processus coracoideus Kirschner Wire Drilling locator under preceding no suitable mirror so that processus coracoideus is fixed on glenoid cavity suitable position under mirror and is more stranded
It is difficult.So it is to carry out drilling through for bone road by surgical experience at present, so that final tunnel position has part partially
Difference, and influence final surgical effect.
And since between different patients, shoulder joint dissection individual difference is larger, and due to modus operandi and approach not
Together, processus coracoideus interception volume is multifarious, so corresponding operating theater instruments is to solve relevant issues at present.
