Description
Technical field
This utility model belongs to medical auxiliary material field, relates to a kind of CT of being used for, the localized imaging label of MRI navigating surgery.
Background technology
Along with the development of clinical image technology, computer image processing technology, operation guiding system is used widely at neurosurgery, orthopaedics, hals,Nasen und Ohrenheilkunde.Carry out navigating surgery, at first need to obtain patient's thin slice scan data with CT, MRI image documentation equipment, image data with patient is loaded in the operation guiding system then, the two and three dimensions image of reconstruction operations position organ structure on the work station of system reaches and utilizes the imaged image guiding doctor operation that undergos surgery thereby utilize device such as infrared ray position finder that registration is carried out in the locus that rebuilds on patient's real space position and the work station.To achieve these goals, need gather a plurality of gauge points on one's body, require these gauge point positions to fix patient, and can imaging on CT, MRI image documentation equipment, so that carry out registration, registration.The gauge point of current use has two classes: a class is the anatomical landmarks point, and another kind of is handmarking's thing.Because the anatomical landmarks point at positions such as human body head is not directly perceived, be difficult to accurately choose, and in order to improve the positioning accuracy of the wild focus of operation art, generally need choose more gauge point near the position of the wild focus of operation art, and additional handmarking's thing is clear and easy to see, therefore can stick on the position of any needs as required, using artificial label to carry out registration is most common form clinically at present.
At present, the complete dependence on import of the label of domestic clinical use costs an arm and a leg, and as medical disposable material, each operation needs 6-10, has greatly increased medical treatment cost, thereby has limited the extensive popularization and the use of this new technique of operation guiding system.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and defective, and a kind of CT of being used for, the localized imaging label of MRI navigating surgery are provided.Described label is mainly used in based on the operation guiding system of image datas such as CT, MRI and gathers gauge point on one's body patient, so that register on image, and uses related equipment and label registration.
The square paste that a kind of CT of being used for of this utility model, the localized imaging label of MRI navigating surgery are decided hole, profile band fillet for the center bidding is made up of developing body (1), forming cavity (2), counterdie (3), adhesive glue (4) and release paper (5).Described forming cavity (2) is positioned at developing body (1) surface, and counterdie (3), adhesive glue (4) and release paper (5) place developing body (1) bottom.
In this utility model, its center bidding of described developing body (1) is decided the hole, and its profile is the square of being with fillet.
In this utility model, described developing body (1) adopts the spongy colloid that contains calcium carbonate and glycerol composition to make, and common described developing body (1) is of a size of 14x14mm, thickness is 5mm;
In this utility model, it is material that described forming cavity (2) and counterdie (3) all adopt the PE thin film.
In this utility model, it is material that described adhesive glue (4) adopts medical pressure-sensitive adhesive.
What this utility model was used for CT, MRI navigating surgery positioning and imaging label passes through the preparation of following method and step:
1) diameter is arranged is the developing body (1) that 4mm demarcates hole, profile band fillet at the spongy colloid center of being prefabricated into that will contain calcium carbonate and glycerol composition, and described developing body (1) is of a size of 14x14mm, thickness is 5mm;
2) use general tablet, capsule class packer, press its conventional technological process: thin film is carried, heating, molding: make forming cavity (2), filler: put into developing body (1), involution: cover counterdie (3), gluing and cover backing paper: adhesive glue (4), release paper (5), stamping-out profile and center positioning hole are made this utility model and are used for CT, MRI navigating surgery positioning and imaging label.
This utility model is used for CT, MRI navigating surgery positioning and imaging label in use, at first tears release paper (5) off, then it is sticked on the surface that needs check point; Because developing body (1) contains calcium carbonate and glycerol composition, therefore when doing CT, MRI scanning, the developing body in this imaging label just can be high density signal and manifest, and the Kong Ze at developing body center does not develop, just form the demarcation center naturally, be used for demarcating the preceding registration of registration and art.
This utility model imaging signal is strong, is easy to identification, and the stated accuracy height is convenient to the navigating surgery registration, and manufacturing process is simple, and is easy to process, and cost is low, and price is far below external similar imported product, the cost performance height has very high economic benefit, is widely used in the location at CT, MRI navigating surgery.
The utlity model has following advantage:
1, this navigating surgery positioning and imaging label imaging signal is strong, is easy to identification; The stated accuracy height is convenient to registration.
2, manufacturing process is simple, and is easy to process.
3, cost is low, and price is far below external similar imported product, cost performance height.
For the ease of understanding, this utility model is described in detail below by the drawings and specific embodiments.It needs to be noted that specific embodiments and the drawings only are in order to illustrate, obviously those skilled in the art can illustrate according to this paper, and this utility model is carried out various corrections or change, and these corrections and changing also will be included within this patent scope.
