Meanwhile, controllable suction and flushing bypass are realized, and probability of iatrogenic cross infection is effectively decreased.
Description
Technical field
The present invention relates to technical field of medical instruments, specifically a kind of multi-pore channel surgery tractor.
Background technology
During operation, need to reach with surgery tractor tractive operative incision the object exposing visual area, be convenient to operation technique.Reducing the replacing number of times of apparatus, realization " a tool multipotency ", is that guarantee is performed the operation smoothly and shortens the guarantee of operating time.
At present, there is following problem in surgery tractor conventional in clinical position: the surgery tractor that 1, hospital is used is substantially all single hook structure, only unidirectional tractive can be carried out, therefore assistant's held by both hands double hook is all needed operative incision to be carried out to the tractive of subtend when major part, and assistant adopts the posture of both hands subtend tractive surgery tractor not only to put to no little inconvenience to assistant, also disturbs the position of patient to a certain extent; 2, the handle length of drag hook can not regulate fixing, by assistant with hand-held continuous tractive, can only not only waste a large amount of labour force, long tractive surgery tractor, arm can be caused uncomfortable, easily cause fatigue; 3, in art and postoperative irrigation operative site time, directly topple over normal saline, easily cause liquid splash, infiltration isolation scarf contaminated operation district; 4, drag hook is separated use with suction catheter, adds in art the number of times changing apparatus, the fluency of impact operation; 5, suction function and pre-washing function share a pipeline (especially endoscopic surgery), easily cause iatrogenic cross-contamination, have certain probability to make attached wall tumor cell Implantation matastasis.
Application number is " 200920040170.7 ", Authorization Notice No. is " CN 201404249Y ", name is called that the Chinese utility model patent of " Special hanging draw hook for neck single small-cut endoscope in thyroid operation " discloses a kind of special suspensory retractor of cervical region single small incision Endoscopic Thyroidectomy with suction function, comprise: drag hook handle, be arranged on the drag hook end on drag hook handle two ends, drag hook end is respectively equipped with suction aspirator tip.This special drag hook has suction function, a large amount of ultrasonic smog produced can be siphoned away in operation process.This utility model is only applicable to the open scope assisted surgery of minimal incision *, and complete endoscopic surgery is also inapplicable, and suction pump position is fixed, and attractived region limits to, and cannot position suction to the hemorrhage or oozing of blood in operating cavity.
Application number is " 200420052593.8 ", Authorization Notice No. is " CN 2745517Y ", name is called that the Chinese utility model patent of " cavity mirror thyroid operation retractor " discloses a kind of cavity mirror thyroid operation retractor, described cavity mirror thyroid operation retractor is formed through bending process by tinsel, drag hook body is " V " font at the wide end, the front end of drag hook body is needle point, the near wide bottom of drag hook body both arms is to bending about 150 ° of angles, direction of drag hook bar, the plane of drag hook body and drag hook bar are 90 ° of angular distortions, and drag hook handle is arc.In use, thrust with the skin of needle point outside cervical region of drag hook, then through over-rotation drag hook, whole drag hook is inserted thyroid intracavity, under the assistance of chamber mirror elastic separating plier, with the coupler body of drag hook, the Anterior jugular muscles separated is pulled to outside, reach and expose thyroid object.But, the top of its drag hook body is sharp keen needle point, after entering intracavity, the potential risk puncturing carotid arteries is there is when adjusting drag hook position, and this drag hook only can as unidirectional tractive, endoscopic exposure of surgical field still needs to be realized, once body of gland is larger by the apparatuses such as elastic separating plier unidirectional tractive offside body of gland, lack the spatial spread of offside, this drag hook can not obtain the satisfied visual field.
Therefore, lacking one at present effectively can expose visual area, can alleviate again assistant because continuing the inconvenience that brings of subtend tractive surgery tractor and feeling of fatigue in art, realizes " washing " " suctions " simultaneously and shunts, reduce the multifunctional drag hook of iatrogenic cross-contamination probability.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, there is provided one effectively can expose visual area, assistant in art can be alleviated again because of the inconvenience that continues both hands subtend tractive and bring and feeling of fatigue, realize " washing " " suctions " simultaneously and shunt, reduce the multi-pore channel drag hook of iatrogenic cross-contamination probability.
