DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] An embodiment of a magnetic resonance real-time monitoring support cover during head surgery of the present invention is as follows: Figures 1 to 8 As shown, it includes a supporting base frame 100 , a supporting mechanism 200 and a cover body 300 .

[0021] The support frame 100 is installed on the operating table and is located below the patient's head. The length of the support frame 100 in the horizontal direction is adjustable to adapt to the head width of different patients.

[0022] The cover body 300 is used to install the magnetic resonance real-time monitoring device 400; specifically, the cover body 300 is a transparent acrylic plate, and the cover body 300 includes a flat plate and two side plates.

The second tension spring 240 is connected to the connecting rod unit 250 through the second pull rope 270, providing a downward pulling force for the connecting rod unit 250. The tension of the second tension spring 240, the sum of the gravity of the cover body 300 and the magnetic resonance real-time monitoring device 400 are balanced with the tension of the first tension spring 230, so that the cover body 300 can stay in the adjusted position after moving.

[0024] The connecting rod unit 250 is provided to provide the cover body 300 with the freedom to move arbitrarily within a certain vertical plane, so as to facilitate the flexible adjustment of the cover body 300 and provide a suitable monitoring position for the magnetic resonance real-time monitoring device 400. The coordinated use of the first tension spring 230 and the second tension spring 240 enables the cover body 300 to stay at any position after moving without the need for additional locking, and the operation is simple and easy to use.

[0025] In this embodiment, the connecting rod unit 250 includes a first rod 251, a second rod 252, a third rod 253, a fourth rod 254, a fifth rod 255, a sixth rod 256, a seventh rod 257 and an eighth rod 258. The eighth rod 258 is vertically arranged and fixedly connected to the cover body 300 in a detachable manner, so as to facilitate the replacement of the cover body 300. One end of the first rod 251 is hinged to the rotating frame 220, and the other end is hinged to one end of the second rod 252. The other end of the second rod 252 is hinged to one end of the third rod 253; the other end of the third rod 253 is hinged to the upper end of the eighth rod 258; one end of the fourth rod 254 is hinged to the rotating frame 220 and is coaxial with the hinge axis of the first rod 251 and the rotating frame 220; one end of the fifth rod 255 is hinged to the rotating frame 220 and is located at the hinge position of the fourth rod 254 and the rotating frame 220. The sixth rod 256 is hinged at both ends to the other ends of the fourth rod 254 and the fifth rod 255, and the hinged position of the sixth rod 256 and the fourth rod 254 is hinged to the third rod 253 at the same time, and the third rod 253 is divided into two sections, and the section connected to the second rod 252 is the first section, and the section connected to the eighth rod 258 is the second section; the seventh rod 257 is hinged at both ends to the hinged position of the fifth rod 255 and the sixth rod 256 and the lower end of the eighth rod 258. The above-mentioned hinge axes are all horizontal axes and are parallel, and the first rod 251 is equal to the first section in length, the second rod 252 is equal to the fourth rod 254 in length, and the first rod 251, the second rod 252, the first section of the third rod 253 and the fourth rod 254 define a first parallelogram. The fourth rod 254 and the fifth rod 255 are equal in length, the distance between the fourth rod 254 and the fifth rod 255 and the hinged position of the rotating frame 220 is equal to the length of the sixth rod 256, and the fourth rod 254, the fifth rod 255, the sixth rod 256 and the rotating frame 220 define a second parallelogram. The sixth rod 256 and the eighth rod 258 are equal in length, the seventh rod 257 and the second section of the third rod 253 are equal in length, and the sixth rod 256, the seventh rod 257, the eighth rod 258 and the second section of the third rod 253 define a third parallelogram. The three parallelograms work together to enable the eighth rod 258 and the cover body 300 connected to the eighth rod 258 to move to any position on the plane where the eighth rod 258 is located. One end of the first pull rope 260 is connected to the first tension spring 230 , and the other end passes over the rotating frame 220 and is connected to the fourth rod 254 from above the fourth rod 254 ; one end of the second pull rope 270 is connected to the second tension spring 240 , and the other end is connected to the first rod 251 from below the first rod 251 .

[0026] In this embodiment, the hinge position of the first rod 251 and the second rod 252 is located at the side of the hinge position of the first rod 251 and the rotating frame 220 away from the eighth rod 258, and the hinge position of the fourth rod 254 and the sixth rod 256 is located at the side of the hinge position of the first rod 251 and the rotating frame 220 close to the eighth rod 258. A horizontally extending first hinge shaft 221 is fixed on the rotating frame 220, and one end of the fourth rod 254 and the first rod 251 are both rotatably mounted on the first hinge shaft 221; a mounting groove is provided on the first hinge shaft 221, and a clamping block 222 is installed in the mounting groove along the radial direction of the first hinge shaft 221, and a clamping tooth is provided on a side of the clamping block 222 away from the center of the first hinge shaft 221, and a spring 223 is connected between the clamping block 222 and the first hinge shaft 221; the inner circle of the fourth rod 254 and the first rod 251 that cooperate with the first hinge shaft 221 are both provided with a tooth groove. A plurality of pulleys are installed on the rotating frame 220 to guide the first pull rope 260 to bypass the first hinge shaft 221, and the tension of the first pull rope 260 restricts the block 222 in the installation groove of the first hinge shaft 221; when the first pull rope 260 or the second pull rope 270 breaks, the tension of the first pull rope 260 is insufficient to restrict the block 222, so that the block 222 extends under the action of the spring 223 to engage with the teeth on the fourth rod 254 and the first rod 251, restricting the rotation of the fourth rod 254 and the first rod 251, thereby preventing the cover body 300 from falling. The first pull rope 260 fits with the portion of the block 222 where the teeth are not provided, so as to prevent the first pull rope 260 from being worn. The block 222 is restricted in the first hinge shaft 221 by the tension of the first pull rope 260. When the first pull rope 260 or the second pull rope 270 breaks, the first pull rope 260 will relax, and the block 222 will mesh with the tooth grooves on the fourth rod 254 and the first rod 251 under the action of the spring 223, restricting the rotation of the fourth rod 254 and the first rod 251, thereby restricting the rotation and movement of the first parallelogram and the second parallelogram, and further restricting the rotation and movement of the third parallelogram, and the cover body 300 is locked in the current position to prevent it from falling and injuring the patient. In some other embodiments, the first pull rope 260 can also be artificially relaxed to lock the connecting rod unit 250, and then the cover body 300 is locked to prevent the operator from accidentally touching and affecting the monitoring results. For example, the end of the first tension spring 230 or the second tension spring 240 connected to the rotating frame 220 is separated from the initial connection position, or the position of one of the pulleys is changed so that it no longer presses against the first pull rope 260 or the second pull rope 270.

[0027] In this embodiment, a plurality of connection holes are provided on the first rod 251 and the fourth rod 254 along their respective length directions. The first pull rope 260 is connected to different connection holes of the fourth rod 254 to adjust its tension, and the second pull rope 270 is connected to different connection holes on the first rod 251 to adjust its tension.

[0028] In this embodiment, the rotating frame 220 includes a frame body 224 and a partition 225, and the frame body 224 is rotatably installed on the matching seat 210; the partition 225 is fixed in the frame body 224, and divides the interior of the frame body 224 into two areas, the first rod 251, the second rod 252 and the third rod 253 are located in the same area, and the fourth rod 254 and the fifth rod 255 are located in another area, so as to prevent the first rod 251, the second rod 252, the third rod 253 and the fourth rod 254, the fifth rod 255 from interfering with each other during movement.

[0029] In this embodiment, the support frame 100 includes a bottom rod 110 and two clamping heads 120. The bottom rod 110 is a telescopic rod with adjustable length. Specifically, the telescopic rod includes a sleeved outer tube and an inner rod. A bolt is installed on the outer tube. The bolt passes through the outer tube and abuts against the inner rod to lock the length of the bottom rod 110. The two clamping heads 120 are respectively fixed to the upper sides of both ends of the bottom rod 110, and are respectively used to clamp the two sides of the patient's head. The matching seat 210 is detachably mounted on one of the clamping heads 120. Specifically, the matching seat 210 is mounted on the clamping head 120 through a locking stud.

[0030] In this embodiment, the interior of the mating seat 210 is hollow and has a columnar space; a rotating column that is mating with the interior of the mating seat 210 is provided on the lower side of the frame 224, and the rotating column is inserted into the mating seat 210 and is rotatably mating with the mating seat 210. In some other embodiments, a plurality of ball grooves may be provided in the inner ring of the mating seat 210, and an elastic ball head may be provided on the circumference of the rotating column, and when the frame 224 rotates relative to the mating seat 210, the elastic ball head is sequentially engaged with different ball grooves, thereby locking the position of the frame 224.

[0031] When the present invention is used, the bottom bar 110 of the support frame 100 is installed on the operating table, and the length of the bottom bar 110 is adjusted according to the width of the patient's head, so that the two clamping heads 120 are respectively located on both sides of the patient's head, which is convenient for limiting the patient's head. After that, the matching seat 210 is vertically installed on one of the clamping heads. Since the multiple rods of the connecting rod unit 250 are connected to each other to define three mutually related and parallelogram-shaped four-bar linkages, the cover body 300 can move freely in the plane where the eighth rod 258 is located, and determine the appropriate monitoring position for the real-time magnetic resonance monitoring component 400. After the adjustment, since the first tension spring 230 and the second tension spring 240 provide upward and downward pulling forces for the connecting rod unit 250 through the first pull rope 260 and the second pull rope 270 respectively, the cover body 300 is always in a balanced state of force during the movement, and can be locked in the adjusted position after the movement, without the need for an additional locking structure, and is easy to use.

[0032] During use, if the first pull rope 260 or the second pull rope 270 breaks due to wear, the first pull rope 260 will loosen, and the block 222 will engage with the teeth on the fourth rod 254 and the first rod 251 under the action of the spring 223, limiting the rotation of the fourth rod 254 and the first rod 251, thereby limiting the rotation and movement of the first parallelogram and the second parallelogram, and further limiting the rotation and movement of the third parallelogram, and the cover body 300 is locked in the current position to prevent it from falling and injuring the patient, which is safer.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
