Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a registration body surface positioning clamp and fastening assembly. Background Technology
[0002] Existing registration positioning fixtures mainly include a fixture body, a first fixing part, and a second fixing part. The first fixing part is located on one side of the main body and is used to fix the sensor. The second fixing part is located around the fixture body and is used to fix the CT imaging marker ball. However, such a structural design makes the entire registration positioning fixture large in size and occupies a large surgical area. Utility Model Content
[0003] Therefore, this utility model aims to solve the problem that existing registration positioning clamps are large in size and occupy a large surgical area, thereby providing a registration body surface positioning clamp and fastening components.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0005] On one hand, this utility model provides a registration body surface positioning fixture, including: a body, the central area of the front of the body being a sensor fixing area for mounting a sensor; the edge area of the front of the body being a marking area for mounting a CT imaging marker ball; a first marking point being provided in the sensor fixing area; and a second marking point, a third marking point, and a fourth marking point being provided in the marking area.
[0006] Furthermore, the second marker point is located in the marker area at the top of the sensor fixing area; the third marker point is located in the marker area on one side of the bottom of the sensor fixing area; and the fourth marker point is located in the marker area on the other side of the bottom of the sensor fixing area.
[0007] Furthermore, if the distance between the centers of the first and second markers is n, the distance between the centers of the first and third markers is p, and the distance between the centers of the first and fourth markers is q, then n, p, and q form an arithmetic sequence with a common difference greater than the diameter of the CT imaging marker ball.
[0008] Furthermore, three fixing stickers are spaced apart on the back of the main body.
[0009] Furthermore, the three fixed stickers are located at the three vertices of the triangle, respectively.
[0010] Furthermore, the fixing adhesive is a medical double-sided adhesive.
[0011] Furthermore, the sensor fixing area is provided with clips on both the left and right sides for fixing the sensor.
[0012] Furthermore, the body is a substrate made of non-metallic material.
[0013] Furthermore, the first, second, third, and fourth marker points are not in the same plane along the thickness direction of the body.
[0014] On the other hand, this utility model provides a fastening assembly, including the registration body surface positioning clamp as described in any of the above claims, and further including a sensor and a CT imaging marker ball; the sensor is disposed in the sensor fixing area; the first marker point, the second marker point, the third marker point and the fourth marker point are all provided with the CT imaging marker ball.
[0015] The technical solution of this utility model has the following advantages:
[0016] The registration body surface positioning clamp provided by this utility model has a second, third, and fourth marking point all located in the marking area surrounding the sensor fixing area. Both the marking points and the sensor fixing area are located on the main body. Compared with the registration positioning clamps in the prior art, no additional structural installation marking points are required besides the main body, which helps to reduce the overall size of the main body. Moreover, since the first marking point is located within the sensor fixing area, the overall size of the main body can be further reduced, thus reducing the area occupied in the surgical field.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0027] like Figure 1 , Figure 2 As shown, this embodiment provides a registration body surface positioning fixture, including: a body 1, the central area of the front of the body 1 being a sensor fixing area 2 for mounting a sensor; the edge area of the front of the body 1 being a marking area 3 for mounting a CT imaging marker ball; a first marking point 4 being provided in the sensor fixing area 2; and a second marking point 5, a third marking point 6, and a fourth marking point 7 being provided in the marking area 3.
[0028] For example, for the first marker point 4, a blind hole can be provided in the sensor fixing area 2 to form the first marker point 4. When the CT imaging marker ball is installed in the first marker point 4, the CT imaging marker ball protrudes slightly and does not affect the installation of the sensor above. As for the second marker point 5, the third marker point 6, and the fourth marker point 7, they can include a cylindrical part and a blind hole provided on the top of the cylindrical part, or they can be blind holes directly set on the plane of the marking area 3.
[0029] For example, for the second marker 5, the third marker 6, and the fourth marker 7, one of the markers may be located in the marker area 3 at the top of the sensor fixing area 2, and the other two markers may be located in the marker area 3 at the bottom of the sensor fixing area 2, or two of the markers may be located in the marker area 3 at the top of the sensor fixing area 2, and the other marker may be located in the marker area 3 at the bottom of the sensor fixing area 2.
[0030] The registration body surface positioning fixture provided by this utility model has a second marking point 5, a third marking point 6, and a fourth marking point 7, all of which are set in the marking area 3 around the sensor fixing area 2. The marking points and the sensor fixing area 2 are all located on the body 1. Compared with the registration positioning fixtures in the prior art, no additional structural installation marking points need to be set in addition to the body 1, which is beneficial to reduce the volume of the entire body 1. Moreover, since the first marking point 4 is set in the sensor fixing area 2, the volume of the entire body 1 can be further reduced, reducing the occupation of the surgical area.
[0031] In this configuration, the second marker point 5 is located in the marker area 3 at the top of the sensor fixing area 2; the third marker point 6 is located in the marker area 3 on one side of the bottom of the sensor fixing area 2; and the fourth marker point 7 is located in the marker area 3 on the other side of the bottom of the sensor fixing area 2. With this arrangement, the second marker point 5, the third marker point 6, and the fourth marker point 7 are located at the three vertices of a triangle, resulting in a smaller overall size and reduced space occupied in the surgical area compared to the prior art design where the first marker point 4, the second marker point 5, the third marker point 6, and the fourth marker point 7 are located at the four vertices of a rectangle.
[0032] Preferably, the distance between the centers of the first marker point 4 and the second marker point 5 is n, the distance between the centers of the first marker point 4 and the third marker point 6 is p, and the distance between the centers of the first marker point 4 and the fourth marker point 7 is q. Then n, p, and q form an arithmetic sequence with a common difference greater than the diameter of the CT imaging marker sphere. For example, the actual values of n, p, q, and the common difference can be designed as needed. With this configuration, the center coordinates of the CT imaging marker sphere at the first marker point 4 are closest to the average coordinates of the centers of the four CT imaging marker spheres, which facilitates distinguishing the positions of each marker point, automatically acquiring the image coordinates of the spheres, and differentiating their order.
[0033] like Figure 3 As shown, the back of the main body 1 is provided with three fixing stickers 9 spaced apart. For example, the three fixing stickers 9 can be located at the three vertices of a triangle. This arrangement, compared to the existing technology which uses four contact surfaces, makes it easier to adhere to the skin. For example, the fixing stickers 9 can be medical double-sided adhesive tapes to prevent damage to human skin.
[0034] The sensor fixing area 2 has clips 8 on both the left and right sides for fixing the sensor. The design of these clips 8 can be the same as the clip structure of the registration positioning fixture in the prior art, which facilitates the installation and removal of the sensor.
[0035] The main body 1 is a substrate made of a non-metallic material. This design prevents interference with the scanning structure.
[0036] Among them, the first marking point 4, the second marking point 5, the third marking point 6 and the fourth marking point 7 are not in the same plane along the thickness direction of the body 1.
[0037] Another embodiment provides a fastening assembly including the registration body surface positioning clamp as described in any of the above embodiments, and further including a sensor and a CT imaging marker ball; the sensor is disposed in the sensor fixing area 2; the first marker point 4, the second marker point 5, the third marker point 6 and the fourth marker point 7 are all provided with the CT imaging marker ball.
[0038] In summary, the registered body surface positioning jig in this application allows the sensor and each marker point to be fixed inside the jig. The jig has a smaller volume and consists of only one part, so it does not occupy surgical space. Moreover, the jig can fit and be fixed to human skin.
[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
