Description
Technical field
This utility model relates to medical instruments field technology, particularly a kind of reducing abdominal cavity puncture outfit.
Background technology
Along with the development of TV tech and camera technique, take laparoscopic surgery as the Minimally Invasive Surgery method of representative, develop rapidly in recent years.Minimally-invasive treatment technology for feature and progressively obtain the accreditation of numerous doctors, is an inexorable trend of following operation method development with its minor operation, little wound.At present, relate to Intraabdominal operation in gynecological, department of general surgery etc., just progressively changed into intracavity Minimally Invasive Surgery by open operation.Increasing doctor is by laparoscopic technique training, and operation technique is more and more consummate, in the popularizing of situation of all-level hospitals, played important effect, has also promoted the development of peritoneoscope and instrument further on the other hand.
Laparoscopic visualization passage and the indispensable step of operating theater instruments passage are set up in sleeve pipe puncture, and abdominal cavity puncture outfit is the essential tool implementing this step.Laparoscopic operation method makes several minimal incision * at patient's waist and belly, and oddi's sphincteroplasty is generally at 0.5 ~ 1 centimetre, and thus patient can not form the cicatrix of strip after recovery.On otch, each insertion puncture casing is as service aisle, and peritoneoscope and operating theater instruments are all operated by these pipelines; The operating theater instruments that laparoscopic surgery uses is through special lengthening operating theater instruments, and image is sent on monitor by peritoneoscope by whole operation, performs the operation under television monitoring, can reach the surgical effect same with abdominal.
Traditional abdominal cavity puncture outfit is made up of two parts, and one is puncture casing, and one is puncture needle.Namely can be used for puncturing operation after puncture casing and puncture needle combination, after puncture completes, puncture casing indwelling is on stomach wall, and puncture needle takes out and abandons.Puncture casing is formed primarily of parts such as body, air shuttle valve, seal valve, gas injection valves.
Patent documentation 201110338794.9, CN102499737B, disclose a kind of visual puncturing device manufacture method of disposable celiac mirror and implement the perforator of the method, realize optionally to carry out operation technique down by camera module, the safety of effective raising puncturing operation, reduces the generation of malpractice.But its puncture casing does not possess the function of reducing, can only the corresponding operating theater instruments using a kind of external diameter specification.
In laparoscopic surgery, what generally adopt is 2 ~ 5 holes, and place peritoneoscope for one, position is generally on underbelly navel, and remaining hole is for placing operating theater instruments.At present, widely used laparoscopic surgical instruments specification, divides with external diameter and has 5mm, 10mm, 12mm etc., need to support the use on the puncture casing of corresponding internal diameter, to avoid pneumoperitoneum to leak gas, and normally carrying out of impact operation.Clinically, an operation needs the operating theater instruments using plurality of specifications usually, and is used alternatingly in operation process.For a puncture position, the puncture casing after fixing is that inconvenience is changed.In use, for 10mm puncture casing, when using the operating theater instruments of 10mm specification, gap between the top cover endoporus of sleeve pipe and apparatus less (being generally 0.5 ~ 2mm), when apparatus swings, because sealing cap is elastic material, its ductility can ensure that the endoporus of sealing cap is adjacent to apparatus, therefore favorable sealing property; When using the operating theater instruments of 5mm specification, the gap between the top cover endoporus of sleeve pipe and apparatus very large (being generally 3 ~ 5mm), when apparatus swings, the elastic deformation of sealing cap is not enough to make its endoporus be adjacent to apparatus, and creates gas leakage.
Therefore on a puncture casing, using different operating theater instruments and do not cause gas leakage, is the engineering problem needing solution badly that we face.
At present, the methods such as transducer are used to solve this problem clinically.But the methods such as this extra use transducer can increase the triviality of operation, and the cooperation of transducer itself and perforator also easily goes wrong, and increases operation risk.
At present, some abdominal cavity puncture outfits are also had to adopt the mode of integrated transducer to solve this problem.Patent documentation 201220702209.9, CN202932967U, discloses a kind of visual abdominal cavity exocoel dilator, is also provided with transducer above its fixed cover, transducer has base, submounts has upper cover plate, has rotating disk below upper cover plate, and rotating disk can rotate between upper cover plate and base, sealing gasket is had between rotating disk and base, air pollution operation path can be prevented, rotating disk has the hole of multiple different size, different types of operating theater instruments can be made to pass through.
Be similar to above-mentioned patent, the perforator of existing band internal diameter translation function, generally transducer be set by the end integrated ground at puncture casing, then adopt the conversion regime of piece-picking type, carry out different internal diameter conversions.The conversion regime of this piece-picking type, by on plectrum parts (as rotating disk, turning the sheet components such as band), pre-set the through hole of several different inner diameters, then move or rotate these plectrum parts, the through hole in corresponding aperture is toggled it to the position corresponding with the pipeline of puncture casing, then the operating theater instruments inserting corresponding external diameter specification is performed the operation.Although it solves the problem of internal diameter conversion, owing to adopting the conversion regime of piece-picking type, cause the end of puncture casing bulky, be unfavorable for that operation is carried out.And the transducer of this piece-picking type, after repeatedly stirring, easily there is problems such as damaging, stuck, para-position is inaccurate, affect operation and carry out in its plectrum.In addition, existing internal diameter transducer is generally fixed on puncture casing, can not dismantle, once there is the situation blocking surgical device, then has to whole puncture casing all to be pulled out.
Utility model content
For above-mentioned deficiency, this utility model object is, the convenience providing a kind of reasonable in design, easy to operate, effective raising abdominal paracentesis to perform the operation, the reducing abdominal cavity puncture outfit of safety.Adopt novel rotary variable-diameter device, changed the diameter of endoporus by the mode rotated, do not need extra transducer, the operating theater instruments of plurality of specifications can be used in same puncture casing.And the variable-diameter structure science of rotary variable-diameter device is ingenious, by driver plate, slide block, the cooperatively interacting of slide rail dish, reducing the volume of rotary variable-diameter device to greatest extent simultaneously, make reducing more safe and reliable.This perforator delicate structure, sealing is reliable, can ensure carrying out smoothly of operation.
For achieving the above object, the technical scheme provided is this utility model:
A kind of reducing abdominal cavity puncture outfit, comprise casing bit and puncture needle device, it is characterized in that, described casing bit is provided with rotary variable-diameter device, this rotary variable-diameter device comprises driver plate, slide rail dish and slide block, wherein, described driver plate is provided with the arcuate groove at more than two places, and described slide rail dish is provided with the slide rail at more than two places, described slide block comprises more than two pieces, correspondence is located on the slide rail of slide rail dish, and described slide block is provided with guide pillar, and this guide pillar matches with the arcuate groove of driver plate; Driver plate rotates, and the arcuate groove on driver plate drives slide block outwards or inwardly to move along the slide rail of slide rail dish by the guide pillar of slide block, thus makes internal diameter become large or reduce.
