Description
Technical field
The present invention relates to field of measuring technique under arthroscope, the side of joint inner structure is measured under more particularly to a kind of arthroscope
Method and device.
Background technology
Arthroscope is the rodlike optical instrument of diameter 5mm for observing intra articular structure or so a kind of, is closed for diagnosis and treatment
Save the endoscope of illness.The essential structure of arthroscope is an optical system, and center is the stick mirror system for acquiring image, is around
The optical fiber of light source is imported, outside is metal coating sheath.Arthroscope is one group of photoelectric instrument for reflecting intra-articular situation, by closing
Save the compositions such as lens head, camera, host, display and cold light source.The camera lens of arthroscope is 4-5 millimeters thick to be more than 20 centimetres long
Thin stick, for being inserted into articular cavity, stick includes one group of optical fiber and one group of perspective, and light is passed to joint by optical fiber, thoroughly
Depending on then intra-articular image is spread out of.Outside joint, optical fiber is connected by an optical cable with cold light source, and such cold light source can
To illuminate joint；Lens are connected by one camera with host and display, so as to intra-articular image reflection to display
On device.Arthroscope is applied not only to the diagnosis of disease, and is widely used for the treatment of joint disease.
Motor system disease is common disease, frequently-occurring disease.Motor system disease mostly occurs in joint part.Joint mainly includes
Knee joint, shoulder joint, elbow joint, wrist joint, hip joint, ankle-joint etc..The main joint inner structure easily damaged include ligament,
Tendon, meniscus, broad-mouthed receptacle for holding liquid lip, cartilage, fossa intercondyloidea etc..The motor system disease in terms of once intra-articular structural damage occurs can be serious
People’s lives quality is affected, especially for sportsman, games results can be seriously affected and even terminate sports career.
The measurement of the radial line of joint inner structure, form and area is for understanding the essence of intra-articular structural form and damaged structure
It really repairs and has great importance.For example Anterior Cruciate Ligament Ruptures Hou Gu road forms and area influence the healing feelings of graft
Condition；Fossa intercondyloidea form and size have an impact the rate of breaking again after the generation of disruption of the anterior and posterior cruciate ligaments and ligament reconstructive；Half a month
Plate form and the size of covering cartilage surface have an impact osteoarthritis after meniscus prosthetic；The area coverage of shoulder sleeve stop
Healing and functional rehabilitation after prosthetic of tucking inside the sleeve to shoulder have a major impact；The accurate of cartilage damage defect size is measured for graft
The accurate matching for repairing cartilage damage has great importance.
The prior art is summarized by taking cartilage damage as an example below.
The symptom of cartilage damage performance mainly has：Articular cartilage lacks blood supply, innervation and lymphatic return, cartilage
Cell only accounts for the 1-5% of articular cartilage volume, cartilage cell's division growth inferior capabilities, leads to the self-regeneration energy of cartilage damage
Power is poor.After articular cartilage damage, if cannot timely and effectively treat, may be in progress osteogenic arthritis
(Osteoarthritis, OA) brings heavy economy and mental burden to patient.
Skin grafing and mending and organizational project prosthetic are the research hotspots of clinical treatment cartilage damage at present, skin grafing and mending art packet
Include Autologous Chondrocyte transplantation, autologous bone chondrocyte cell transplantation, self cartilage block transplanting, allogenic chondrocytes, of the same race
Allograph bone chondrocyte cell transplantation.Than wide, especially zoopery common are in cartilage tissue engineered application material source
Absorbable material polycaprolactone (PCL), dextrorotation polylactic acid (PDLA), l-lactic acid (PLLA), fibroin, decalcification cortex bone
Stent, decalcified cancellous bone stent, Electrospun stent and hyaluronic acid scaffold etc..Surgical procedure mode mainly include cutting operation and
Cartilage grafting and organizational project art are the modus operandis risen in recent years under total joint arthroscopic diagnosis, wherein total joint mirror, entirely
Operation has the advantages that wound is small, it is fast to restore under arthroscope, but the matching of the size shape of graft and cartilage defect is always
Without complete accurate measuring method, currently used measuring method is measuring scale method and stent general laws under arthroscope.
Gage method is that gage is put in articular cavity under mirror, and the magnitude numerical value of defect is read under mirror and describes shape.Under mirror
Gage method is most common mensuration in current clinical and zoopery.As shown in Figure 1, after the completion of cartilage defect is cleared up, it will
Measuring scale is put into intra-articular, the length of multiple and different radial lines is measured, according to the shape of cartilage defect under mirror and the number of calibrated line
Value, trimming graft are allowed to match with defect.The method is for defect regular shape and the smaller cartilage damage of defect is than calibrated
Really.But since articular surface is mostly with cambered, measuring scale is scleroid ruler so that measuring scale is difficult completely and articular surface
It is estimated value to attach completely or even measure size sometimes, in addition to this, arthroscope there are certain amplification factor, arthroscope
Camera lens in itself more certain angle, and usually 30 ° of angles, cause measuring result error larger, especially for defect shape
Irregular and larger defect cartilage damage, measuring result error bigger are very poor so as to cause graft and defect matching.
Stent general laws is that graft is modified using the apparatus mould of existing different size, by the transplanting after finishing
Object is compared with cartilaginous lesion site, and cartilaginous lesion site is trimmed to the size and shape identical with mold.Due to mold
Mostly regular shape, based on circle, and cartilage defect is mostly irregular defect, for matching rule shape graft then need by
Defect is trimmed to regular shape.This method is likely to damage normal cartilage, inevitably not advising cartilage damage
The then normal cartilage of an area or cartilage islands removal part.
In the implementation of the present invention, inventor has found that the prior art has at least the following problems：It is measured under arthroscope
Ruler method is primarily present problem：Due to the radian of articular surface in itself, measuring scale is mostly metal product or the processing of matter hard material under mirror
Into with damage location it is difficult to attach completely, measurement error is larger, causes graft and defect matching poor.And stent general laws
The problem of being primarily present be：It, inevitably will be soft in order to which cartilage damage is made preferably to be matched with the graft of regular shape
The region of disorder of bone injury or a normal cartilage removal part for cartilage islands, have aggravated cartilage damage, and to irregular area
Normal cartilage or cartilage islands also weaken the effect of its physiology stent while remove.
