Description
Technical field
The invention belongs to the field of medical instrument technology, are related to a kind of shoulder joint for sports medical science associated joint videoendoscopic surgery
Videoendoscopic surgery upper limb multi-angle hitch frame more particularly to a kind of hitch frame for arthrocsopic surgery.
Background technology
Injury gained in sports is a kind of common damage, can mostly be related to the big Minor articulus in whole body many places, and with current compatriots for
Movement have deep love for and degree of participation is constantly soaring, the age that is related to of injury gained in sports also tends to rejuvenation year by year.And just because of year
Light requirement of the people for postoperative beauty, so the more preferred orthopaedics minimally invasive surgery arthroscopes of the treatment for being related to injury gained in sports at present carry out
Treatment.
Minimally invasive surgery is cross-centennial one of the high-new surgery technological achievement of clinical medicine circle.Minimally invasive surgery instrument is represented as
Endoscope.Such as utilize duct or the miniature incision of keyhole size, 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
It is in the former can reduce surgical wound area, avoid infecting caused by significantly the exposing of in-vivo tissue, and can make disease
People's more block is fully recovered, and hospital stays and medical expense are shortened.Minimally Invasive Surgery instrument 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.Foreign countries are 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 is continuously improved with medical instrument, and arthrocsopic surgery is received with its notable advantage by more and more doctors and patient,
Gospel is brought for numerous patients with joint diseases.It is grown rapidly by decades, has been applied to most of neck of orthopaedics now
Domain, especially in terms of knee arthroscope surgical technic, various new methods are even more to emerge one after another, and are maked rapid progress.
As the open surgery characterized by " major trauma " develops to the Minimally Invasive Surgery direction characterized by " microtrauma ",
It explores the Minimally Invasive Surgery instrument of new generation towards natural cavity and has become inexorable trend.A workman must first sharpen his tools if he is to do his work well.In face of life
The demand for ordering medical development, the principles of science for exploring advanced surgical instrument 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 instrument creates the mixing together for being related to the subjects such as machine science, life science and clinical medicine at the scientific basic with manufacture, leads to
The basic theory and technique study of Minimally Invasive Surgery instrument are crossed, new treatment principle and tool, correlative study will be provided for clinical medicine
The new change of medical technology will be expedited the emergence of.
When carrying out multinomial arthroscopic surgery operation, since the joint space in certain joints is narrow, it is not convenient to use interior peep
Mirror instrument is operated, and arthroscope hitch frame is first about to the joint space traction opening in involved joint with the need, with profit
In the arthroscopic procedures for carrying out all directions in the potential lacuna expanded.
The problem of arthrocsopic surgery hitch frame is mainly the agent structure of hitch frame at present, fixed mostly with wirerope to hang
Arm forms, and mechanical strength is poor, needs to coordinate between surgical procedure more barrels of pure water to be pressed on bottom and stabilization is kept just can normally to make
With.Meanwhile the arm steel cable structure stability of existing arthrocsopic surgery hitch frame is very low, causes to be shaken by traction suffering limb in art
It shakes, interferes surgical procedure, and easily cause to pollute.
Firstly the need of solution be exactly arthrocsopic surgery hitch frame stability problem, due to currently on the market without suitable
Hitch frame structure to solve the problems, such as to use at present when shake it is unstable so that lacuna expansion in joint is unstable, to be operated under mirror
Add many potential uncertain factors, simultaneously because shoulder joint neural blood vessel is abundant, it is careless slightly can be to serious iatrogenic
Damage, to influence final surgical effect.
