Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a support cover for real-time intraoperative magnetic resonance monitoring in head surgery. Background Technology

[0002] During head surgery, real-time monitoring of the patient's intracranial condition is necessary. Current technology typically involves installing a transparent acrylic cover on a cranial support frame and fixing the monitoring device to it. The cover supports the monitoring device while ensuring normal patient breathing, and its transparent structure does not interfere with the device's operation. However, in practice, the cover and monitoring device need to be adjusted to fit the patient's head. Because the cover is fixed to the support frame, adjustment is inconvenient, and changing the monitoring device's position on the cover is not precise enough, affecting the accuracy of the monitoring results. Summary of the Invention

[0003] This invention provides a support cover for real-time intraoperative magnetic resonance monitoring in head surgery, to solve the problem of inconvenient adjustment of existing support covers.

[0004] The present invention provides a support cover for real-time intraoperative magnetic resonance monitoring in head surgery, which adopts the following technical solution:

[0005] A support cover for real-time magnetic resonance imaging (MRI) monitoring during head surgery includes a support base, a support mechanism, and a cover body. The support base is installed on the operating table and located below the patient's head. The cover body is used to install the MRI real-time monitoring device. The support mechanism includes a mating seat, a rotating frame, a first tension spring, a second tension spring, and a linkage unit. The mating seat is installed on the support base, and the rotating frame is installed on the mating seat around a vertical axis. The rotating frame is connected to the cover body through the linkage unit, and the linkage unit allows the cover body to move arbitrarily relative to the rotating frame in a certain vertical plane. The first tension spring is connected to the linkage unit through a first tension rope, providing an upward tension to the linkage unit. The second tension spring is connected to the linkage unit through a second tension rope, providing a downward tension to the linkage unit. The sum of the tension of the second tension spring, the weight of the cover body, and the MRI real-time monitoring device is balanced with the tension of the first tension spring, so that the cover body can remain in the adjusted position after movement.

[0006] Optionally, the linkage unit includes a first rod, a second rod, a third rod, a fourth rod, a fifth rod, a sixth rod, a seventh rod, and an eighth rod. The eighth rod is vertically arranged and fixedly connected to the cover. One end of the first rod is hinged to the rotating frame, and the other end is hinged to one end of the second rod. The other end of the second rod is hinged to one end of the third rod. The other end of the third rod is hinged to the upper end of the eighth rod. One end of the fourth rod is hinged to the rotating frame and is coaxial with the hinge axis between the first rod and the rotating frame. One end of the fifth rod is hinged to the rotating frame and is located directly below the hinge position of the fourth rod and the rotating frame. Both ends of the sixth rod are hinged to the other ends of the fourth rod and the fifth rod, respectively. The hinge position of the sixth rod and the fourth rod is simultaneously hinged to the third rod, dividing the third rod into two segments. The section connected to the second rod is the first section, and the section connected to the eighth rod is the second section; the two ends of the seventh rod are respectively hinged to the hinge positions of the fifth and sixth rods and the lower end of the eighth rod; all the hinge axes are horizontal axes and parallel, and the first rod is equal in length to the first section, the second rod is equal in length to the fourth rod, the fourth rod is equal in length to the fifth rod, the distance between the hinge positions of the fourth and fifth rods and the rotating frame is equal to the length of the sixth rod, the sixth rod is equal in length to the eighth rod, and the seventh rod is equal in length to the second section; one end of the first pull rope is connected to the first tension spring, and the other end passes over the top of the rotating frame and connects to the fourth rod from above; one end of the second pull rope is connected to the second tension spring, and the other end connects to the first rod from below.

[0007] Optionally, the hinge position of the first rod and the second rod is located on the side away from the eighth rod where the first rod is hinged to the rotating frame, and the hinge position of the fourth rod and the sixth rod is located on the side closer to the eighth rod where the first rod is hinged to the rotating frame; a horizontally extending first hinge shaft is fixed on the rotating frame, and one end of the fourth rod and the first rod are rotatably mounted on the first hinge shaft; a locking block is provided on the first hinge shaft, and locking teeth are provided on the locking block, with a spring connecting the locking block and the first hinge shaft; the inner ring of the end of the fourth rod and the first rod that mates with the first hinge shaft is provided with a toothed groove; multiple pulleys are installed on the rotating frame to guide the first pull rope to pass over the locking block on the first hinge shaft, and the tension of the first pull rope restricts the locking block within the first hinge shaft; when the first pull rope or the second pull rope breaks, the tension of the first pull rope is insufficient to restrict the locking block, causing the locking block to extend and engage with the toothed grooves on the fourth rod and the first rod, restricting the rotation of the fourth rod and the first rod, thereby preventing the cover from falling.

[0008] Optionally, multiple connecting holes are provided on the first and fourth rods along their respective length directions. The first pull rope is connected to different connecting holes on the fourth rod to adjust its tension, and the second pull rope is connected to different connecting holes on the first rod to adjust its tension.

[0009] Optionally, the rotating frame includes a frame body and a partition plate. The frame body is rotatably mounted on the mating seat. The partition plate is fixed inside the frame body and divides the interior of the frame body into two areas. The first rod, the second rod, and the third rod are located in the same area, and the fourth rod and the fifth rod are located in the other area.

[0010] Optionally, the length of the support frame in the horizontal direction is adjustable.

[0011] Optionally, the support frame includes a base rod and two clamping heads. The base rod is a telescopic rod with an adjustable length. The two clamping heads are fixed to the upper sides of both ends of the base rod and are used to clamp the patient's head on both sides. A mating seat is detachably installed on one of the clamping heads.

[0012] Optionally, the cover can be made of transparent acrylic sheet.

[0013] Optionally, the cover includes a flat plate and two side plates. The flat plate is horizontally positioned, and its upper side is used to install a real-time magnetic resonance monitoring device. The two side plates are located on both sides of the flat plate and are both vertically positioned. They are both connected to the flat plate, and the connection is transitioned by an arc plate.

[0014] Optionally, the mating seat is hollow inside and has a columnar space inside; a rotating column is provided on the lower side of the frame to mate with the interior of the mating seat. The rotating column is inserted into the mating seat and rotatably mates with the mating seat.

[0015] The beneficial effects of the present invention are: the support cover for real-time magnetic resonance monitoring during head surgery is provided with a linkage unit to give the cover body the freedom to move arbitrarily in a certain vertical plane, which facilitates the flexible adjustment of the cover body and provides a suitable monitoring position for the real-time magnetic resonance monitoring device. In addition, the cooperation of the first tension spring and the second tension spring allows the cover body to stay in any position after movement without the need for additional locking. The operation is simple and convenient.

[0016] Furthermore, the tension of the first pull rope is used to restrict the locking block within the first hinge shaft. When the first or second pull rope breaks, the first pull rope will loosen, and the locking block will engage with the toothed grooves on the fourth and first rods under the action of the spring, restricting the rotation of the fourth and first rods, thereby restricting the rotation and movement of the first and second parallelograms, and further restricting the rotation and movement of the third parallelogram. The cover is locked in its current position to prevent it from falling and injuring the patient. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] An embodiment of the support cover for real-time intraoperative magnetic resonance monitoring in head surgery according to the present invention, such as... Figures 1 to 8 As shown, it includes a support base 100, a support mechanism 200, and a cover 300.

[0029] The support frame 100 is installed on the operating table and located below the patient's head; the length of the support frame 100 in the horizontal direction is adjustable to accommodate different head widths of patients.

[0030] The cover 300 is used to install the real-time magnetic resonance monitoring device 400; specifically, the cover 300 is a transparent acrylic plate, and the cover 300 includes a flat plate and two side plates. The flat plate is horizontally set, and its upper side is used to install the real-time magnetic resonance monitoring device 400; the two side plates are located on both sides of the flat plate and are both vertically set, and are both connected to the flat plate, and the connection is transitioned by an arc plate.

[0031] The support mechanism 200 includes a mating seat 210, a rotating frame 220, a first tension spring 230, a second tension spring 240, and a connecting rod unit 250. The mating seat 210 is mounted on the support base 100, and the rotating frame 220 is mounted on the mating seat 210 around a vertical axis. The rotating frame 220 is connected to the cover 300 through the connecting rod unit 250, and the connecting rod unit 250 allows the cover 300 to move arbitrarily relative to the rotating frame 220 in a certain vertical plane. The first tension spring 230 is connected to the linkage unit 250 via the first pull rope 260, providing an upward pulling force to the linkage unit 250. The second tension spring 240 is connected to the linkage unit 250 via the second pull rope 270, providing a downward pulling force to the linkage unit 250. The sum of the pulling force of the second tension spring 240, the weight of the cover 300 and the magnetic resonance real-time monitoring device 400 is balanced with the pulling force of the first tension spring 230, so that the cover 300 can stay in the adjusted position after moving.

[0032] The linkage unit 250 provides the cover 300 with the freedom to move arbitrarily in a certain vertical plane, which facilitates the flexible adjustment of the cover 300 and provides a suitable monitoring position for the magnetic resonance real-time monitoring device 400. The cooperation of the first tension spring 230 and the second tension spring 240 allows the cover 300 to stay in any position after moving without the need for additional locking, making it simple to operate and convenient to use.

[0033] In this embodiment, the linkage 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 detachably fixed to the cover 300 for easy replacement of the cover 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 between 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 between the fourth rod 254 and the rotating frame 220. The position is directly below; the two ends of the sixth rod 256 are hinged to the other ends of the fourth rod 254 and the fifth rod 255, respectively, and the hinge positions of the sixth rod 256 and the fourth rod 254 are simultaneously hinged to the third rod 253, dividing the third rod 253 into two segments, with the segment connected to the second rod 252 being the first segment and the segment connected to the eighth rod 258 being the second segment; the two ends of the seventh rod 257 are hinged to the hinge positions of the fifth rod 255 and the sixth rod 256, and the lower end of the eighth rod 258, respectively. All the above hinge axes are horizontal axes and parallel, and the first rod 251 is equal in length to the first segment, the second rod 252 is equal in length to the fourth rod 254, and the first segment of the first rod 251, the second rod 252, and the third rod 253, together with the fourth rod 254, define the first parallelogram. The fourth rod 254 and the fifth rod 255 are of equal length. The distance between the hinged positions of the fourth rod 254 and the fifth rod 255 and the rotating frame 220 is equal to the length of the sixth rod 256. 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 is of equal length to the eighth rod 258. The seventh rod 257 is of equal length to the second segment of the third rod 253. The sixth rod 256, the seventh rod 257, the eighth rod 258, and the second segment of the third rod 253 define a third parallelogram. The three parallelograms work together to allow the eighth rod 258 and the cover 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 top of the rotating frame 220 and is connected to the fourth rod 254 from above; 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.

[0034] In this embodiment, the hinge position of the first rod 251 and the second rod 252 is located on the side away from the eighth rod 258 of the hinge position between the first rod 251 and the rotating frame 220, and the hinge position of the fourth rod 254 and the sixth rod 256 is located on the side closer to the eighth rod 258 of the hinge position between the first rod 251 and the rotating frame 220. 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 rotatably mounted on the first hinge shaft 221. An installation groove is provided on the first hinge shaft 221, and a locking block 222 is installed radially along the first hinge shaft 221 in the installation groove. The side of the locking block 222 away from the center of the first hinge shaft 221 is provided with locking teeth, and a spring 223 is connected between the locking block 222 and the first hinge shaft 221. The inner ring of the end of the fourth rod 254 and the first rod 251 that mates with the first hinge shaft 221 is provided with toothed grooves. Multiple pulleys are installed on the rotating frame 220 to guide the first pull rope 260 to pass around the first hinge pin 221, and the tension of the first pull rope 260 restricts the locking block 222 within the mounting groove of the first hinge pin 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 locking block 222, causing the locking block 222 to extend under the action of the spring 223 and 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 300 from falling. The first pull rope 260 engages with the portion of the locking block 222 without teeth to prevent wear on the first pull rope 260. The tension of the first pull rope 260 restricts the locking block 222 within the first hinge pin 221. When the first pull rope 260 or the second pull rope 270 breaks, the first pull rope 260 loosens, and the locking block 222, under the action of the spring 223, engages 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 restricting the rotation and movement of the first parallelogram and the second parallelogram, and further restricting the rotation and movement of the third parallelogram. The cover 300 is locked in its current position to prevent it from falling and injuring the patient. In some other embodiments, the first pull rope 260 can also be loosened manually to lock the linkage unit 250, thereby locking the cover 300 to prevent the operator from accidentally touching it 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 can be disengaged from its initial connection position, or the position of one of the pulleys can be changed so that it is no longer pressing against the first pull rope 260 or the second pull rope 270.

[0035] In this embodiment, the first rod 251 and the fourth rod 254 are provided with multiple connecting holes along their respective length directions. The first pull rope 260 is connected to different connecting holes of the fourth rod 254 to adjust its tension, and the second pull rope 270 is connected to different connecting holes of the first rod 251 to adjust its tension.

[0036] In this embodiment, the rotating frame 220 includes a frame body 224 and a partition plate 225. The frame body 224 is rotatably mounted on the mating seat 210. The partition plate 225 is fixed inside the frame body 224 and divides the interior of the frame body 224 into two regions. The first rod 251, the second rod 252, and the third rod 253 are located in the same region, and the fourth rod 254 and the fifth rod 255 are located in another region, preventing the first rod 251, the second rod 252, the third rod 253 from interfering with each other during movement.

[0037] In this embodiment, the support frame 100 includes a base rod 110 and two clamping heads 120. The base rod 110 is a telescopic rod with an adjustable length. Specifically, the telescopic rod includes a sleeved outer tube and an inner rod. Bolts are installed on the outer tube, passing through the outer tube and abutting against the inner rod to lock the length of the base rod 110. The two clamping heads 120 are respectively fixed to the upper sides of both ends of the base rod 110 and are used to clamp the patient's head on both sides. A mating seat 210 is detachably installed on one of the clamping heads 120. Specifically, the mating seat 210 is installed on the clamping head 120 by a locking stud.

[0038] In this embodiment, the mating seat 210 is hollow inside and has a cylindrical space inside. A rotating column is provided on the lower side of the frame 224 to engage with the interior of the mating seat 210. The rotating column is inserted into the mating seat 210 and rotates with it. In some other embodiments, the inner ring of the mating seat 210 may have multiple ball grooves, and elastic ball heads are provided around the rotating column. When the frame 224 rotates relative to the mating seat 210, the elastic ball heads sequentially engage with different ball grooves, thereby locking the position of the frame 224.

[0039] In the present invention, a support cover for real-time intraoperative magnetic resonance monitoring in head surgery is used such that the base rod 110 of the support frame 100 is installed on the operating table, and the length of the base rod 110 is adjusted according to the width of the patient's head, so that the two clamping heads 120 are located on both sides of the patient's head, which facilitates the restriction of the patient's head. Then, the mating seat 210 is vertically installed on one of the clamping heads. Since the multiple rods of the linkage unit 250 are interconnected to define three interrelated four-bar linkages, all of which are parallelograms, the cover 300 can move freely in the plane where the eighth rod 258 is located, determining a suitable monitoring position for the real-time magnetic resonance monitoring device 400. After adjustment, since the first tension spring 230 and the second tension spring 240 provide upward and downward tension to the linkage unit 250 through the first pull rope 260 and the second pull rope 270 respectively, the cover 300 is always in a balanced state of force during movement and can be locked in the adjusted position after movement without the need for an additional locking structure, making it convenient to use.

[0040] 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. Under the action of the spring 223, the locking block 222 will engage with the toothed grooves on the fourth rod 254 and the first rod 251, restricting the rotation of the fourth rod 254 and the first rod 251. This, in turn, restricts the rotation and movement of the first parallelogram and the second parallelogram, and further restricts the rotation and movement of the third parallelogram. The cover 300 is locked in its current position to prevent it from falling and injuring the patient, thus improving safety.

[0041] 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 principles of the present invention should be included within the protection scope of the present invention.
