Abstract
The invention provides a lotus-root-shaped guide locator and belongs to a medical instrument. The lotus-root-shaped guide locator mainly solves the technical problems that radiation injures operators and the amount of radiation on patients is excessively large in the existing guide pin location technology. According to the technical scheme, the lotus-root-shaped guide locator is characterized by comprising a cylindrical body (1). One end of the cylindrical body (1) is the holding end, and the other end of the cylindrical body (1) is the locating end extending into a human body. The portion, at the port of the locating end, of a through hole is provided with a locating ring (3). The lotus-root-shaped guide locator is mainly applied to guide and location of percutaneous puncture of a guide pin.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly the guide pin locator tool in a kind of operation.
Background technology
Guide pin locator tool is conventional apparatus in operation at present, and it is generally the column with a through hole, and after positioning end is for location, a certain specific position, guide pin inserts from through hole, to reaching preposition along through hole.In open operation, although above-mentioned positioning action can carry out under visual state, but the sclerotin face of anchor point may cannot carry above-mentioned locating apparatus because of a variety of causes, or at guide pin point along in unique through hole insertion process, because slippage cannot accurately be fixed on this anchor point.
Main aspect is, along with medical science less invasive techniques develops rapidly, less invasive techniques is widely applied in orthopaedics field, but orthopaedics Minimally Invasive Surgery often need to accurately be located at sclerotin face with guide pin percutaneous puncture under radioscopy, next step operation of being allowed for access after accurately to be positioned, therefore whether successfully guide pin percutaneous puncture location becomes Minimally Invasive Surgery committed step.But in percutaneous puncture, because cannot look at straight, behind guide pin apparatus location, need to confirm by X-ray examination whether location is correct again, but because it only arranges a through hole, once locate incorrect, often need guide pin locator tool repeatedly to puncture, repeatedly X-ray examination is confirmed, repeatable operation.Even if it is accurately located at skin surface by superficial x-ray locating apparatus (as orientation film etc.), but owing to there is certain distance in position point sclerotin face and skin surface, even if guide pin locator tool of the prior art can accurately be located at skin surface, also can be because of radioscopy time, produce error, making to insert guide pin through skin surface is difficult to once insert accurately in the positioning action of sclerotin face, often need repeatedly repeatedly under X ray, to adjust operation, even continuing adjustment operation under radioscopy.There is blindness in the guide pin positioning action that therefore adopts above-mentioned guide pin locator tool to carry out, one-time positioning success rate is not high, waste the quality time in operation, in this process, also cannot avoid operator and patient to be subject to the direct radiation of X ray, being subject to for a long time low dose radiation can make people produce the situations such as fatigue, weak, alopecia, insomnia, oral ulcer and leucocytes reduction, thrombocytopenia, even can also there is immunologic hypofunction, the situations such as carcinogenic, teratogenesis, have restricted the fast-developing and application of less invasive techniques to a certain extent.
Summary of the invention
The object of the invention is for prior art exist technical problem, provide a kind of convenient to operation, amount of radiation is low, the Rhizoma Nelumbinis shape orienting locator of accurate positioning.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of Rhizoma Nelumbinis shape orienting locator, it comprises column 1, and described column 1 one end is holding end, and the other end is the positioning end that stretches into human body, and described column is provided with 2 or 2 above through holes 2 that longitudinally run through, that be parallel to each other.
As to further improvement of the present invention, described column 1 is that holding end is the cylinder of plane, and the positioning end of described column 1 is plane or taper seat, and described column 1 adopts X ray material thoroughly to make.
As to further improvement of the present invention, described through hole 2 is provided with roentgenopaque telltale mark on the port limit of positioning end.
As to further improvement of the present invention, it is uniform that multiple through holes 2 are radially layered ring-type around the centre bore 4 of column 1 home position.
As to further improvement of the present invention, multiple through holes 2 are radially disorder distribution.
As to further improvement of the present invention, described telltale mark is the locating ring 3 that is embedded in through hole 2 edges, and described locating ring 3 adopts roentgenopaque material to make.
As to further improvement of the present invention, described telltale mark is the roentgenopaque location coating 5 that is attached to through hole 2 edges.
Above-mentioned Rhizoma Nelumbinis shape orienting locator is applied to operation guide pin percutaneous puncture location.
As to further improvement of the present invention, described operation is orthopaedics Minimally Invasive Surgery.
The invention has the beneficial effects as follows: guide pin locator tool provided by the invention, owing to being provided with multiple through holes that be arranged in parallel in its column, can realize location twice, in the fixation procedure of column, complete the roughly location including site undetermined, by selecting suitable concrete a certain through hole accurately to locate as guide pin puncturing hole, provide the chance of the accurate regioselective of secondary again in multiple through holes of column.The present invention only need cover site undetermined in the time that apparatus is located, greatly reduce the positioning requirements of apparatus when fixing, can greatly shorten the operating time of guide pin location, improve guide pin location efficiency, especially be adapted to the percutaneous puncture location in Minimally Invasive Surgery, be conducive to applying of Minimally Invasive Surgery.
