Advantageously, auxiliary diagnostic equipment 1 can be used to CT scan, ultrasonic scanning or nuclear magnetic resonance scanning.When being used for CT scan and ultrasonic scanning, be not limited to for the material of auxiliary diagnostic equipment and adopt nonmagnetic or diamagnetic material, can use other any suitable material.
In the nuclear magnetic resonance scanning diagnostic imaging; Exert an influence for fear of image in scanning process to the patient; Each parts of auxiliary diagnostic equipment; That is to say that pedestal 2, first support 3, second support 4 and driving device 5 etc. process by diamagnetism or non-magnetic material, and auxiliary diagnostic equipment 1 preferably has near the coil that is used to improve image quality that is arranged on the patient position.In this embodiment, coil is the multichannel phased-array coil, and coil can be launched and/or the received RF pulse in imaging process.For the ease of dynamic chek, the coil that is designed is wanted and can be reserved bigger space for joint motions.
In the embodiment shown in fig. 1, driving device 5 can drive first support 3 and second support 4 at suitable angular range internal rotation, to satisfy patient's body is positioned to the required position of effective medical diagnosis scanning.For example in the diagnosis of neck marrow dynamic scan, preferably can in 0-45 ° scope, regulate first and second supports 3 and 4, bend the position patient's position being adjusted to.
According to the present invention, the driving device 5 of above-mentioned auxiliary diagnostic equipment 1 can have a plurality of embodiment.In the embodiment shown in fig. 1; Driving device 5 is a manual driving device; It for example comprises first driving shaft 7 that is rotatably installed on the pedestal 2 and is rotatably installed in second driving shaft 8 on the said pedestal 2; First driving shaft 7 makes first support 3 do pivoting action through drive mechanism 7a, 7b and 7c, and second driving shaft 8 can make second support 4 do pivoting action through another set of identical drive mechanism.Here; Above-mentioned drive mechanism for example comprises the belt pulley 7c that is installed on first driving shaft or second driving shaft, with the odontoid belt 7a of belt pulley engagement, can not straight line to move but rotating mode is installed on the pedestal 2 and belt pulley (not shown) that is meshed with odontoid belt 7a and screw rod 7b; Wherein on the belt pulley that is installed on this pedestal, offer threaded through hole, screw rod 7b at one end inserts in this through hole with engagement system and links at the other end and first support 3 or second support 4.
Certainly; The drive mechanism of second driving shaft 8 also can be different from the drive mechanism of first driving shaft 7; As shown in Figure 1; For example it comprise as the screw rod 7b of the part of second driving shaft 8 be opened in the tapped through hole on the pedestal 2, the screw rod 7b part of second driving shaft 8 in other words inserts in this tapped through hole with engagement system, second driving shaft links at the other end and second support 4.Certainly, also can expect adopting other suitable drive mechanism, like gear drive etc.
In the above-described embodiments; In order in the diagnostic imaging scanning process, to remain on the correct position through the position of first and second supports with the people; Screw rod 7b is equipped with movable piece 6 on the other end; Movable piece 6 butts first support 3 towards the side of pedestal 2, pivot in the desired angle scope thereby promote this support.In embodiment as shown in Figure 1, movable piece 6 also can be expected other any suitable structure for to be fixedly connected on the dumbbell shaped member on the screw rod 7b, for example hollow ball, platy structure etc.Match with screw rod 7b through movable piece 6, when the rotation of first driving shaft 7 stops, just can and remain on the position of wanting 3 adjustment of first support.Advantageously, for the ease of operation, on first driving shaft 7 and second driving shaft 8, the operation handwheel that is used to drive first driving shaft or second drive shaft turns is housed respectively.
In another embodiment of driving device 5; Driving device for example comprises the cylinder or the hydraulic cylinder of cylinder body and the piston rod that can in cylinder body, move; Wherein this cylinder body is arranged on this pedestal, and the external part of piston rod is connected with first support 3 and/or second support 4.Drive through hydraulic pressure or air pressure, above-mentioned two supports can pivot in the desired angle scope.
In another embodiment of driving device 5; This driving device is a Vidacare corp; It for example comprises motor, being installed in first driving shaft 7 and second driving shaft 8 on the pedestal 2 by the mode of motor driven rotation; First driving shaft 7 makes first support 3 do pivoting action through drive mechanism 7a, 7b and 7c, and second driving shaft 8 makes second support 4 do pivoting action through another set of identical drive mechanism.
This drive mechanism for example comprises the belt pulley 7c that is installed on first driving shaft or second driving shaft, with the odontoid belt 7a of this belt pulley engagement, can not straight line to move but rotating mode is installed on the pedestal 2 and belt pulley that is meshed with odontoid belt 7a and screw rod 7b; Wherein on the belt pulley that is installed on the pedestal 2, offer threaded through hole, screw rod 7b at one end inserts this through hole with engagement system and links at the other end and first support 3 or second support 4.
When the above-mentioned auxiliary diagnostic equipment of operation, at first let patient lies on first and second supports 3 and 4 of horizontal positioned, the patient is sent in the scanner.Then, successively or simultaneously drive first and second driving shafts 7 and 8 and rotate, the rotation of first driving shaft 7 drives belt pulley 7c and rotates; And then the odontoid belt 7a that drive is meshed with this belt pulley moves; Thereby drive be installed on the pedestal 2 and with another belt pulley rotation of odontoid belt engagement, and then drive screw 7b vertically moves the result along auxiliary diagnostic equipment 1; By the movable piece on the other end that is installed in screw rod 7b, first and second supports are kept in place.So, just can patient's position be remained on the position that needs, for example help detecting the mistake position in the wrong of neck marrow damage.Having realized can dynamic scan and the purpose of the damage of ad-hoc location scanning body part, thereby has improved the accuracy of diagnosis greatly, for next step correct diagnosis and treatment provide accurate foundation.
In the present invention, above-mentioned auxiliary diagnostic equipment can use with nuclear magnetic resonance scanning equipment, ultrasonic scanning equipment or CT scan coordinative composition of equipments.When this auxiliary diagnostic equipment was used to nuclear magnetic resonance scanning equipment, for fear of in scanning process, patient's image being exerted an influence, pedestal 2, first support 3, second support 4 and driving device 5 all can be processed by diamagnetism or non-magnetic material.
Although above reference implementation example also sees that accompanying drawing describes the present invention, the present invention is not limited to above-mentioned concrete characteristic and design.To those skilled in the art, need be with the size and dimension of each parts of numeric representation in above-mentioned explanation, these can come to confirm as the case may be.For the those skilled in the art that read above description, except given example, under the prerequisite that does not exceed the scope of the invention, many changes and to be equal to the replacement means will be conspicuous.
