Abstract
The utility model discloses a multipurpose probe apparatus for a joint cavity, which belongs to the technique of the medical appliance. The multipurpose probe apparatus for a joint cavity is a novel and multipurpose probe apparatus; when a knee joint mirror is used for checking, traumas can be fully reduced, and the multipurpose probe apparatus for a joint cavity can not only inject liquid in place of a water injection trocar, but also can have a plurality of kinds of exploring, touching, and traction efficiency. The puncture bore diameter of the probe body which is as small as 3 millimeters can directly enter from the lower side of the patella; the probe which is tied with a flat hook-shaped structure can freely extend and bend within the range from 0 to 130 DEG; the multipurpose probe apparatus for a joint cavity can handily enter into a narrow gap for exploding, touching, and dragging an object to lock and fix. The multipurpose probe apparatus for a joint cavity which is favorable to the check of the knee joint scope and the operation under the scope can extend to the operation of the other endoscopes, and the structure is simple.
Description
The invention belongs to medical device technology
The invention relates to the invention of arthroscopy of knee.Arthroscopy of knee is to need the articular cavity full of liquid and assist directly to spy on pathologic changes of knee joint and to look a kind of the modern diagnoses and treatment of operation down at mirror realizing with probe.
The used probe kind of current domestic and international arthroscopy of knee is more.But following shortcoming and defect is arranged; It is bigger when the plain edition probe is operated because of the bending of popping one's head in to patient's damage; Various small-sized probes, its probe or too small, or too small because of flexibility because of flexibility or has weakened due traction action greatly because of crooked major diameter is too short; Straight type and camber probe then only play the thoughts and feelings effect.The tractive effect is more faint.
The irrigation sleeve bobbin of continuing to use so far when knee joint injects liquid about spectroscopy is all taked point of puncture approach on the kneecap basically, its reason capsule on kneecap is easier to also mainly need leave arthroscope body, probe and arthroscopic diagnosis apparatus for because of point of puncture under the kneecap and take inconvenience and get approach under the kneecap the puncture.Just because of this, in some cases, wrinkle because of under the kneecap
Intercept or enuflex position compressing water filling pin hole and occur that liquid is advanced not go in shin femoral joint gap or the liquid of entering is insufficient thereby cause in varying degrees checking difficulty so that defeat result.
Purpose of the present invention is intended to overcome above-mentioned various deficiency, provides a kind of and can reduce completely traumaticly, can finish the liquid that the irrigation sleeve bobbin injects flow velocity Gao Chang, has multiple spy to touch again, and the novel articular cavity of tractive usefulness is used explorer more.
This explorer by pop one's head in 1. probe body 2. the water filling joint 3. jump ring 4. control crank 5. return spring 6. fork 7. wait and form.When control crank was opened, probe kept stretching (0 °) position under the effect of return spring tension force, when pressing control crank, promptly shoulder bar and shift fork by control crank, dialled push-pull bar, made when probe is crooked gradually on demand to reach the angle that needs to be locked.Maximum flexion can reach 130 °, all operation only needs thumb of operator to finish, and saves labour conveniently, simultaneously also can be by per minute under the conventional instillation condition up to the fluid flow of 400ml, replace the high performance perfusion or the drain trocar, required flow also can be regulated by valve.
This explorer designed according to above-mentioned aufbauprinciple, because of probe can freely stretch in the wrong, so enter the joint and can locate the zero degree position when external with complete extracting.Requirement that then can be different with the blockage that need move with the hand according to the object that need are sought and visited in articular cavity is dynamically stretched in the wrong arbitrarily in 0 °～130 ° scopes; Again because probe is the entity of flat, so can enter close clearance; Probe is again a hook formation simultaneously, the slippage that more is enough to avoid moving with the hand tissue.Lockable fastens after reaching the tractive purpose.The puncturing hole of explorer own is little of 3 millimeters, substitute the irrigation sleeve bobbin again and make two passwaies be kept to one, under guaranteeing airtight, unidirectional, kneecap fully in the flow of inlet water, significantly reduced the traumatic of operation, accepted by doctor and patient easily because wound is little, function is many, performance is good, thereby can enlarge the indication of arthroscopy and arthroscopic diagnosis, for common knee joint illness and knee joint injury patient bring glad tidings.
This explorer also can utilize above-mentioned multiple function to extend and go to the inspection operation of other body cavity endoscope.
Claims (4)
1, the present invention is that a kind of articular cavity of being made up of probe body and probe etc. is used explorer more, it is characterized in that it forms by freely stretching probe in the wrong and probe body.
2,, it is characterized in that its probe body is a hollow pipe, and be provided with the water filling joint, to replace the irrigation sleeve bobbin according to the described explorer of claim 1.
3,, it is characterized in that it is a flat hook-type entity according to the described probe of claim 1.
4,, it is characterized in that it is provided with the control probe and freely stretches control crank in the wrong and limited screw according to the described probe body of claim 1.
