Abstract
The present invention relates to a kind of arthroscope and these two kinds of advanced technologies of laser used to the undergo surgery special-purpose operating theater instruments of treatment of the pathological changes of human synovial tissue.It is made up of clamp nut, ratchet, pawl base, pole socket, working beam and cutter head, and laser instrument special and by the optical fiber outgoing laser beam cooperates, and constitutes arthroscopic laser scalpel.The present invention is not only rational in infrastructure, compact, convenient disassembly, and flexible operation, laser energy consumption are minimum, and point of a knife directly contacts with pathological tissues, so can accurately perform the operation, vaporization and light coagulate and stops blooding.This cutter head is 2000 ℃ of high temperature of ability also, and can directly use in aqueous solution, extremely are fit to arthrocsopic surgery.
Description
The present invention relates to a kind of joint tissue be carried out the operating theater instruments of medical operating, be specifically related to a kind of arthroscope and these two kinds of advanced technologies of laser used the undergo surgery special-purpose operating theater instruments of treatment of the pathological changes of human synovial tissue.
Arthroscope and arthrocsopic surgery are state-of-the-art technology in the modern orthopaedic medical treatment field, are characterized under the condition of not opening articular cavity, and by minimum pipeline, the utilization optical principle is the pathological condition of observation chamber inner tissue intuitively; Simultaneously, by the operating theater instruments of special use, under the supervision of arthroscope and closed-circuit television system thereof, the articular cavity inner tissue of pathological changes is accurately reached effective medical operating, to obtain extremely good therapeutic effect and function of joint.But the domestic and international at present operating theater instruments that is machinery used in arthrocsopic surgery.Because arthrocsopic surgery is to carry out under the condition of not opening articular cavity, the space of operative region is narrow and small, and the angle of operating theater instruments operation can not be followed one's bent, and the person accurately holds the dynamics and the degree of accuracy of operation directly to influence the operation technique.Thereby in arthrocsopic surgery, the existing mechanical operating theater instruments that falls behind is compared with advanced person's arthrocsopic surgery, obviously feels incompatible, has restricted further developing and improving of arthrocsopic surgery.
The objective of the invention is advanced person's laser medicine achievement in research is introduced in the arthrocsopic surgery, make full use of that the laser scalpel cutting force is big, speed is fast, directed correct, wound face is little, have the being unsurpassed in excellence property of hemostasis and anti-inflammation simultaneously concurrently, overcome the deficiency of mechanical operating theater instruments, a kind of more advanced and perfect arthroscopic laser scalpel is provided, make have arthropathy patient up to a million can obtain operative treatment fast and effectively approximately every year, thereby produce the huge social benefit.
The present invention is achieved in that by clamp nut, ratchet, pawl base, pole socket, working beam, cutter head and forms; Ratchet and pawl base interference fit; Clamp nut cooperates with pawl base one end external screw thread; The screw-internal thread fit of the external screw thread of the pawl base other end and pole socket one end; The pole socket other end and working beam interference fit; The other end of working beam is 150 ° of bendings, the cutter head cylindrical interference fits that endoporus and sapphire are processed into, and cutter head is cone, and the awl point is the focus of laser beam.
Optical fiber clamp nut, ratchet handle are fed working beam, be about the 0.5mm place until distance cutter head end face, when looking point of a knife and being the best focal point of laser beam, the turn clamp nut, make ratchet shrink fiber clamping, thereby the position relative fixed with fibre-optic terminus and cutter head end face can drop into normal arthroscopic surgery operation.
The present invention is not only rational in infrastructure, compact, demolition convenience, flexible operation, point of a knife hardness height, non-frangibility, safe in utilization, the laser energy consumption is minimum, and 2000 ℃ of high temperature of this cutter head ability, laser output is directly contacted cut tissue, do accurate cutting, vaporization and light coagulate hemostasis, and can directly in aqueous solution, use, the utmost point adapts to arthrocsopic surgery.
The invention will be further described below in conjunction with accompanying drawing:
Accompanying drawing is the structural representation of knife bar, and as shown in the figure, contact type arthroscopic laser scalpel is made up of clamp nut 1, ratchet 2, pawl base 3, pole socket 4, working beam 5, cutter head 6; Clamp nut 1 cooperates with the external screw thread of pawl base 3 one ends; The screw-internal thread fit of the external screw thread of pawl base 3 other ends and pole socket 4 one ends; The other end of pole socket 4 and working beam 5 interference fit; The other end of working beam 5 is 150 ° of bendings, cutter head 6 interference fits that its endoporus and sapphire are processed into; Cutter head 6 is cone.
