Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of Minimally Invasive Surgery apparatus of bone collection.
Background technology
Articular cartilage defect is a class common disease, is often caused by athletic injury, is apt to occur in the youth that quantity of motion is larger.China's articular cartilage damage rate is up to 10 ~ 17%.Defect cartilage long term wear can cause retrograde osteoarthrosis, finally can develop into full osteoarthritis.In China, the patient of osteoarthritis about has 100,000,000 people, and in constantly increasing trend, has the people of suitable vast scale to need to do knee replacements.
Minimally invasive surgery is one of cross-centennial high-new surgery technological achievement of clinical medicine circle.Minimally invasive surgery apparatus be represented as endoscope.As utilized duct or the miniature incision of a keyhole size, the various surgical operations such as the excision of abdominal visceral browser pathological changes, deformity correction, reparation or reconstruction can be carried out, finally reach therapeutic purposes.The surgical operation part that Minimally Invasive Surgery is different from last century is, the former can reduce surgical wound area, avoids significantly exposing of in-vivo tissue and the infection that causes, and patient can be made to fully recover sooner, shortens hospital stays and medical expense.In the body that traditional surgery can cause by Minimally Invasive Surgery apparatus, wound is reduced to minimum degree.Therefore, research is thought, micro-wound surgical operation is one " cross-centennial milestone ".If namely arthroscopic surgery is the major progress of Minimally Invasive Surgery theory at field of orthopaedics, it is the developing direction of joint surgery.Be applied to clinical the seventies gradually from last century abroad, China has introduced this technology in the eighties.In recent years along with the development of medical knowledge and updating of medical apparatus and instruments, arthrocsopic surgery with its significant advantage by increasing doctor and patient accept, for numerous patients with joint diseases bring Gospel.Through fast development decades, be applied to now the most fields of orthopaedics, especially in knee arthroscope surgical technic, various new method emerges in an endless stream especially, makes rapid progress.
Along with the open surgery being feature with " large wound " is to the Minimally Invasive Surgery future development being feature with " microtrauma ", the Minimally Invasive Surgery apparatus of new generation explored towards natural tract becomes inexorable trend.A workman must first sharpen his tools if he is to do his work well.In the face of the demand of life medical development, the principles of science exploring advanced operating theater instruments innovative design and bionical manufacture is one of subjects of mechanical engineering vital task.Current, because Minimally Invasive Surgery device design theory does not have fundamental change, cause many complicated delicate procedure to complete.For a long time, China is not enough in this direction basic research, constrains the development of Minimally Invasive Surgery technique with the apparatus.The mixing together relating to the subjects such as machine science, life sciences and clinical medicine with the scientific basic manufactured created into by Minimally Invasive Surgery apparatus, by rationale and the technique study of Minimally Invasive Surgery apparatus, to provide new treatment principle and instrument for clinical medicine, correlational study will expedite the emergence of the new change of medical skill.
In the process that organization engineered cartilage is transplanted, due to operating theater instruments special under not having arthroscope, need open surgery, periosteum or biomembrane could be carried out intraarticular stitching after exposing cartilaginous lesion site, carry out cell after stitching again to return and plant operation, the otch considerable influence produced is attractive in appearance, and the amplification supervision effect under shortage arthroscope, only lean on the surgical experience that patient itself has, so cartilage transplantation special equipment under needing mirror, thus under making arthroscope, chondrocyte cell transplantation operation becomes possibility.
What first need to solve is exactly gripping work to collagem membrane under arthroscope, and due at present, arthroscopic surgical instruments is not exclusively used in the apparatus kind of cartilage transplantation, and Autologous Chondrocyte transplants the biological collagen film used, very fragile, is very easy to breakage.And gripping is all use nucleus pulposus clamp under existing arthroscopic instrument mirror, but nucleus pulposus clamp cannot carry out the operation of meticulous tenderness, and is also unfavorable for the stitching of the flexible materials such as collagem membrane.
Summary of the invention
The purpose of this utility model is to provide the Minimally Invasive Surgery apparatus that a kind of organization engineered cartilage is transplanted, the gripping fixation problem when technical problem that solve is the stitching of collagem membrane under solution arthroscope.
For solving the problem, this utility model realizes by the following technical solutions: the Minimally Invasive Surgery apparatus that a kind of organization engineered cartilage is transplanted, comprise collagem membrane clamper, described collagem membrane clamper comprises tweezers, tweezers are provided with tweezers head, tweezers bar, and two tweezers heads are the elbow of arc, and the tweezers head being arranged on upper end is provided with the through hole that the surface uniform along this tweezers head distributes, through hole runs through this tweezers head upper/lower terminal end face, is provided with the first barrier portion between adjacent two through holes; The perisporium that the perisporium being arranged on the external diameter of the tweezers head of lower end is provided with along the external diameter of this tweezers head is arranged at intervals with the groove corresponding with lead to the hole site, be provided with the second barrier portion between adjacent two grooves, between groove and the second barrier portion, form rectangle teeth shape structure.
The arc opening of tweezers head described in the utility model is arranged on the right side of tweezers.
The width of tweezers head described in the utility model is 3mm, and the external diameter of tweezers head is 23mm, and internal diameter is 20mm.
The width of through hole described in the utility model is 1mm.
The degree of depth of groove described in the utility model is 1.5mm.
The length of tweezers bar described in the utility model is 120-180mm.
Collagem membrane clamper described in the utility model adopts medical 304 stainless steel materials to make.
This utility model compared with prior art, by being provided with the clamper of arc-shaped forceps head, two tweezers heads are respectively arranged with hole and tooth, close up the sewing hole that rear formation one is passed for operation sewing needle, thus enable operation sewing needle when being clamped with Gripping material, by operation sewing needle, clamped material and cartilaginous edges are sewed up, the problem that gripping when solving the stitching of collagem membrane under arthroscope is fixing; By preparing the total joint arthroscopic diagnosis apparatus that applicable organization engineered cartilage is transplanted, carry out chondrocyte cell transplantation operation under making total joint mirror and become possibility, greatly can reduce the wound of operation for patient, to extensively carrying out of organization engineered cartilage transplanting, there is breakthrough meaning, enrich and improve advanced medical apparatus and instruments, there is provided brand-new cartilage injury to treat new technique and new concept, lead the technological progress of Related Research Domain to have important scientific meaning.
