The device mainly comprises a thin cylindrical transverse shaft, a thick cylindrical transverse shaft, side shafts, a hole buckling plate and a buckling nail. The transverse shafts of the positioning fences are arranged at equal intervals; one end of the side shaft is provided with a fastening nail with a boss structure, and a U-shaped groove in the center of the side shaft enables the side shaft to have scalability during connection; the buckling hole plate at the other end can realize the combined connection of a plurality of unit fences by combining with the buckling nails. In order to ensure the reliability of the positioning fence when the operable part of the human body is positioned, the pressure sensitive adhesive tape is adopted to adjust the positioning fence. The polytetrafluoroethylene material adopted by the structure can be disinfected by iodine or alcohol and other conventional disinfection methods so as to be convenient for subsequent reuse. The positioning fence structure for the percutaneous aspiration biopsy disclosed by the invention aims at improving the accuracy of clinical operation and subsequent reutilization, and has the characteristics of good operation accuracy and strong practicability.
Description
Technical Field
The invention relates to the technical field of medical treatment and medical use and the field of part manufacturing technology.
Background
The percutaneous aspiration biopsy and the percutaneous aspiration treatment can be applied to the examination operation and the accurate positioning treatment of each pathological change part of a human body, the positioning fence can realize the accurate positioning under the guidance of CT, and the aspiration biopsy sampling operation or the positioning treatment operation of the pathological change part is realized. From the existing clinical experience, the percutaneous aspiration biopsy and the percutaneous aspiration treatment are more convenient to operate and higher in diagnosis rate if the positioning is accurate. There is a need to further improve the positioning accuracy of percutaneous needle biopsy and needle treatment to ensure high success rate and quality of the procedure.
The locating device for the percutaneous aspiration biopsy in clinic usually adopts two types, namely a simple self-made fence of temporary adhesive plaster and a disposable adhesive plaster (or operation film) fence. The simple self-made fence of the temporary adhesive plaster is obtained by cutting waste catheters or metal wires for interventional therapy into 5-10 fence cross shafts with a certain length and a side by side interval of 0.5cm-1cm and then simply fixing (such as the adhesive plaster) when in clinical need. Although the manufacturing is simple and the cost is low, the manufacturing is rough, the positioning accuracy is poor, the positioning can be only roughly estimated, and the method cannot be used repeatedly. The disposable adhesive plaster (or operation film) fence is made up by sticking the self-made special metal wire (such as barium sulfate wire) on the medical transparent adhesive tape and medical operation film according to the designed spacing. When in use, the medical operation membrane type fence can be directly used only by cutting off a transparent adhesive tape type fence with a proper length or selecting a medical operation membrane type fence with a required specification according to requirements, and the medical operation membrane type fence is convenient and high in positioning precision but cannot be used repeatedly. Therefore, in order to meet the requirements of different specifications of fences required by percutaneous puncture of lesions of different parts and sizes and solve the problems of high precision and repeated use, a novel fence positioning device structure is provided.
Disclosure of Invention
The utility model aims to provide a structure that makes puncture location point location simple, and positioning accuracy is higher relatively, percutaneous aspiration biopsy art location fence that can use repeatedly to effectively solve present location fence and have the technological problem that the preparation is crude, be difficult to accurate location, can not used repeatedly and lead to the cost to increase.
The structure of the positioning fence for the percutaneous aspiration biopsy comprises a thick cylindrical transverse shaft and a side shaft which are used for fixing the total structure; a cramp and a buttonhole plate which are used for positioning the thin cylindrical cross shaft of the puncture needle and realizing the combined connection and fixation of a plurality of positioning fences.
The thin cylindrical cross shaft is made of barium sulfate wires, and the application process is double die casting.
The thin cylindrical transverse shafts are fixed in the side shafts at two ends and are distributed at equal intervals of 10 mm.
The side shaft is made of polytetrafluoroethylene, and the application process is double die casting.
In one step, the length of the side shaft is 50mm, and the side shaft is small in size so as to be convenient for operation within a small target range and meet the requirements of precision and positioning.
The buckling hole plate and the buckling nails are made of polytetrafluoroethylene, and the application process is double die casting.
Step one, the distance between the vertical center line of the cramp and the near end face of the side shaft is 5mm, and a U-shaped groove with the width of 2mm and the depth of 5mm is formed by taking the vertical center line of the cramp as a reference; the horizontal distance from the center line of the round hole of the buckling hole plate of the plate-shaped structure to the near-end plane of the side shaft is 11 mm.
