Description

Technical Field

[0001] The present invention relates to the technical field of surgical support equipment, and in particular to a neurosurgery clinical surgery support device. Background Art

[0002] Neurosurgery is a branch of surgery. It is a high-level discipline that uses surgery as the main treatment method and applies unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, and its related ancillary structures, such as the skull, scalp, cerebral blood vessels and meninges, as well as injuries, inflammation, tumors, malformations and certain genetic metabolic disorders or functional disorders, such as epilepsy, Parkinson's disease, neuralgia and other diseases. It also explores new diagnosis, treatment and prevention technologies.

[0003] In neurosurgery, especially brain surgery, in order to reduce the impact of the patient's head shaking on the operation, the most commonly used support device is a three-nail head frame. However, in actual use, the three-nail head frame is usually screwed into the patient's head by the doctor, and with the relative squeezing of the two auxiliary head pins, the three head pins are fixed on the patient's skull together. Since the main force is applied by the main head pin on one side, the travel of the main head pin and the auxiliary head pin will be asynchronous during the process of fixing the head pin on the patient's head, resulting in a deviation in the depth of the three head pins inserted into the patient's head. Summary of the invention

[0004] The invention discloses a neurosurgery clinical operation support device, aiming to solve the technical problems that in actual use, the existing three-nail head frame may cause a deviation in the depth of the head nail inserted into the patient's head due to unilateral force application, and the operation is cumbersome and inconvenient.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A neurosurgery clinical operation support device comprises a U-shaped support, a support arm frame installed at the side end of the U-shaped support, and a fixing mechanism for fixing and supporting a patient's head is installed at the side end of the support arm frame;

[0007] A hydraulic mechanism for supplying energy is arranged inside the fixing mechanism;

[0008] A supporting mechanism for supporting the patient's head is provided between the fixing mechanism and the supporting arm frame;

[0009] The hydraulic mechanism drives the fixing mechanism to fix the skull of the patient's head and realizes self-locking of the fixing mechanism at the same time. The rotationally deformed fixing mechanism can cooperate with the supporting mechanism to support the patient's head.

[0010] By providing a fixing mechanism to cooperate with the operation of the hydraulic mechanism, the fixing mechanism can be fixed to the patient's head on both sides synchronously and can self-lock after adjusting the distance, thereby improving the stability and fixing effect of the existing support device when used. At the same time, the flipping supporting mechanism cooperates with the fixing structure to support the patient's head in another form in a deformable manner, which is different from the cumbersome operation of the traditional support device. This device is more convenient and faster.

[0011] In a preferred embodiment, the fixing mechanism includes a center piece connected to the side end of the support arm frame, and two head frame rods are symmetrically distributed on both sides of the center piece. Racks are horizontally fixed to the side ends of the head frame rods, and the two racks are slidably distributed inside the center piece and interspersed. A long gear is distributed in the middle of the center piece, and the long gear is distributed between the two racks and meshingly connected with the two racks. A gear tooth groove is horizontally opened on the side end of the center piece, and the gear tooth groove can be engaged with the side end of the long gear. Arc-shaped nail plates and head nails are respectively slidably installed inside the top side ends of the two head frame rods, and the arc-shaped nail plates and head nails are symmetrically distributed.

[0012] By providing two interlaced rack structures driven by the same gear, the spacing between the two head frame rods can be adjusted synchronously, thereby retaining the function of adjustable fixed spacing of the existing device. At the same time, in conjunction with the operation of the hydraulic mechanism, the long gear and the gear tooth groove can cooperate with each other to achieve rapid self-locking, thereby further improving the convenience of using this equipment.

[0013] In a preferred embodiment, the hydraulic mechanism includes a hydraulic chamber opened at the inner side end of the center piece, and a threaded rotary rod is distributed through the side end of the center piece. The threaded rotary rod passes through the interior of the hydraulic chamber and is rotatably connected to the side end of the long gear. At the same time, the threaded rotary rod is threadedly connected to the side wall of the center piece. A piston plate is horizontally fixed to the middle part of the side end of the threaded rotary rod, and the piston plate is slidably distributed in the interior of the hydraulic chamber. A hydraulic pipe is fixed to the side ends of the two head frame rods, and the hydraulic pipe passes through the interior of the hydraulic chamber. Hydraulic grooves are opened in the interior of the head frame rods, and the hydraulic grooves are connected to the interior of the hydraulic pipe.

[0014] By changing the one-way distance adjustment function of the existing head frame structure into a two-way distance adjustment, cooperating with the rotation of the threaded rotary rod, the arc nail plate and the head nail are driven to move synchronously in the center by means of hydraulic booster, thereby ensuring that the arc nail plate and the head nail are fixed to the patient's head at the same depth, improving the fixing effect of the traditional three-nail bracket, and while the threaded rotary rod rotates, it can synchronously push the long gear to engage with the inside of the gear tooth groove, thereby locking the two head frame rods, ensuring that the distance between the two head frame rods after adjustment will not change, improving the functionality of the device while ensuring the stability of the device during use.

[0015] In a preferred embodiment, the supporting mechanism includes a connecting rod rotatably connected between the support arm frame and the center piece, the outer side of the support arm frame is rotatably sleeved with a socket member, the top of the socket member is rotatably mounted with a lower support, and an upper support is fixed to the side ends of the two head frame rods, and the two upper supports are mirror-symmetrical.

[0016] By providing a foldable lower support structure, when the head frame rod is screwed to fix the patient's head, the U-shaped lower support can assist the doctor in supporting the patient's neck; when the doctor needs to perform ordinary support and fixation on the patient's head, the flipped lower support together with the flipped upward upper support can support the patient's head and face, thereby further improving the functionality of the traditional support device while also improving the convenience of using the traditional support device.

[0017] In a preferred solution, a thread groove is provided between the interlayer of the head frame rod and the head nail, and the thread groove and the head nail are threadedly connected.

[0018] By providing a threaded groove and cooperating with a hydraulic drive, the head nail can be moved and rotated at the same time, so as to be better inserted into the patient's head.

[0019] In a preferred solution, the ends of the two racks away from the fixed head frame rod are each provided with a rib, and the length of the rib is equal to that of the hydraulic pipe.

[0020] The rack travel is limited by the provision of a retaining edge, thereby ensuring that the rack does not slip out of the center piece, and at the same time preventing a gap from forming between the hydraulic pipe and the hydraulic cavity to cause leakage, thereby ensuring the integrity of the operation of the equipment.

[0021] In a preferred solution, the lower bracket and the upper bracket are both filled with sponge, and the minimum distance between the two upper brackets is greater than the maximum outer diameter of the lower bracket.

[0022] By arranging the lower support and the upper support to be both filled with sponge, the comfort of the patient after lying on the pillow is ensured.

[0023] As can be seen from the above, the neurosurgery clinical operation support device provided by the present invention has the following improvements and advantages compared with the prior art:

[0024] Firstly, by changing the one-way distance adjustment function of the existing head frame structure into a two-way distance adjustment, and cooperating with the rotation of the threaded rotary rod, the arc nail plate and the head nail are driven to move synchronously in the center by means of hydraulic booster, thereby ensuring that the arc nail plate and the head nail are fixed to the patient's head at the same depth, thereby improving the fixing effect of the traditional three-nail bracket, and while the threaded rotary rod rotates, it can synchronously push the long gear to engage with the inside of the gear groove, thereby locking the two head frame rods, ensuring that the distance between the two head frame rods after adjustment will not change, thereby improving the functionality of the traditional support device while ensuring the stability of the equipment during use.

[0025] Secondly, by providing a foldable lower support structure, when the head frame rod is screwed to fix the patient's head, the U-shaped lower support can assist the doctor in supporting the patient's neck; when the doctor needs to perform ordinary support and fix the patient's head, the flipped lower support and the flipped upward upper support can surround and support the patient's head and face, thereby further improving the functionality of the traditional support device while also improving the convenience of using the traditional support device.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] A neurosurgery clinical operation support device disclosed in the present invention is mainly used in the scenario of fixing the head of a neurosurgery patient.

[0041] Reference Figures 1 to 12 A neurosurgery clinical operation support device comprises a U-shaped support 1, an arm support frame 2 installed on the side end of the U-shaped support 1, a fixing mechanism 3 for fixing and supporting a patient's head is installed on the side end of the arm support frame 2; a hydraulic mechanism 4 for supplying energy is arranged inside the fixing mechanism 3; a supporting mechanism 5 for supporting a patient's head is arranged between the fixing mechanism 3 and the arm support frame 2; the hydraulic mechanism 4 drives the fixing mechanism 3 to fix the skull of the patient's head and realizes self-locking of the fixing mechanism 3 at the same time, and the rotationally deformed fixing mechanism 3 can cooperate with the supporting mechanism 5 to support the patient's head.

[0042] In this embodiment: the user first fixes the U-shaped support 1 to the side end of the bed, then installs the arm support 2 to the side end of the U-shaped support 1, and causes the supporting mechanism 5 to rest on the patient's neck, then fixes the arm support 2, and finally installs the fixing mechanism 3 to the side end of the arm support 2. After the installation is completed, the user holds both sides of the fixing mechanism 3 and places the fixing mechanism 3 on both sides of the patient's head, pulls the fixing mechanism 3 horizontally, and adjusts the clamping range of the fixing mechanism 3 until the fixing mechanism 3 and the patient's head width ratio are equal. At this time, the user clamps the fixing mechanism 3 on both sides of the patient's head and manually rotates the hydraulic mechanism 4. The hydraulic mechanism 4 applies pressure to the fixing mechanism 3, causing the fixing mechanism 3 to self-lock while the two sides are synchronously inserted into the patient's head, thereby achieving fixation of the patient's head; when the user needs to change the way to fix the patient's head, the user needs to first adjust the position of the arm support 2, and flip the fixing mechanism 3 and the supporting mechanism 5, so that the fixing mechanism 3 and the supporting mechanism 5 cooperate, thereby supporting and fixing the patient's head and face.

[0043] In the above scheme, in order to ensure the stability of the patient's head during surgery and reduce the impact of the patient's head shaking on the surgery, the specific operations are as follows.

[0044] Reference Figures 1 to 12 In a preferred embodiment, the fixing mechanism 3 includes a center piece 301 connected to the side end of the support arm frame 2, and two head frame rods 302 are symmetrically distributed on both sides of the center piece 301. Racks 303 are horizontally fixed to the side ends of the head frame rods 302. The two racks 303 are slidably distributed inside the center piece 301 and are interspersed. A long gear 304 is distributed in the middle of the center piece 301, and the long gear 304 is distributed between the two racks 303 and meshed with the two racks 303. A gear groove 305 is horizontally opened on the side end of the center piece 301, and the gear groove 305 can be engaged with the side end of the long gear 304. Arc-shaped nail plates 306 and head nails 307 are slidably installed inside the top side ends of the two head frame rods 302, and the arc-shaped nail plates 306 and head nails 307 are symmetrically distributed.

[0045] In this embodiment, the user first fixes the U-shaped support 1 to the side end of the bed, then installs the support arm frame 2 to the side end of the U-shaped support 1, and causes the support mechanism 5 to be placed on the patient's neck, then fixes the support arm frame 2, and then installs the center piece 301 to the side end of the support arm frame 2. After the installation is completed, the user holds the two sides of the headrest rods 302 and pulls the headrest rods 302 horizontally, causing the racks 303 located at the side ends of the headrest rods 302 to move relatively around the meshing long gears 304, thereby adjusting the two headrest rods 302. 02, until the spacing between the two head frame rods 302 is equal to the ratio of the width of the patient's head. At this time, the user clamps the two head frame rods 302 on both sides of the patient's head and manually rotates the hydraulic mechanism 4. The hydraulic mechanism 4 applies pressure to the long gear 304, the arc-shaped nail plate 306 and the head nail 307, causing the long gear 304 to move horizontally and insert into the gear tooth groove 305 for self-locking. At the same time, the arc-shaped nail plate 306 and the head nail 307 move relative to each other, thereby being inserted into the patient's head synchronously to fix the patient's head.

[0046] In the above solution, in order to provide sufficient power to drive the arc nail plate 306 and the head nail 307 to operate, the specific operation is as follows.

[0047] Reference Figure 1 to Figure 2 , Figures 4 to 12 In a preferred embodiment, the hydraulic mechanism 4 includes a hydraulic chamber 401 opened at the inner side end of the center piece 301, and a threaded rotary rod 402 is distributed through the side end of the center piece 301. The threaded rotary rod 402 passes through the interior of the hydraulic chamber 401 and is rotatably connected to the side end of the long gear 304. At the same time, the threaded rotary rod 402 is threadedly connected to the side wall of the center piece 301, and a piston plate 403 is horizontally fixed to the middle of the side end of the threaded rotary rod 402. The piston plate 403 is slidably distributed in the interior of the hydraulic chamber 401. A hydraulic pipe 404 is fixed to the side end of each of the two head frame rods 302, and the hydraulic pipe 404 passes through the interior of the hydraulic chamber 401. A hydraulic groove 405 is opened in the interior of the head frame rod 302, and the hydraulic groove 405 is connected to the interior of the hydraulic pipe 404.

[0048] In this embodiment: the user first fixes the U-shaped support 1 to the side end of the bed, then installs the support arm frame 2 to the side end of the U-shaped support 1, and causes the support mechanism 5 to rest on the patient's neck, then fixes the support arm frame 2, and then installs the center piece 301 to the side end of the support arm frame 2. After the installation is completed, the user holds the two sides of the head frame rods 302 and pulls the head frame rods 302 horizontally, causing the racks 303 located at the side ends of the head frame rods 302 to move relative to each other around the meshing long gears 304, thereby adjusting the clamping range of the two head frame rods 302 until the spacing between the two head frame rods 302 is equal to the ratio of the patient's head width. At this time, the user clamps the two head frame rods 302 on the patient. On both sides of the head, manually rotate the threaded rotary rod 402, causing the threaded rotary rod 402 and the piston plate 403 to move toward the inside of the hydraulic chamber 401, and squeeze the liquid inside the hydraulic chamber 401, causing the liquid to be pressurized and move toward the inside of the hydraulic pipe 404 and the hydraulic groove 405, and apply pressure to the arc-shaped nail plate 306 and the head nail 307. At the same time, the moving threaded rotary rod 402 will synchronously push the long gear 304, causing the long gear 304 to move horizontally and insert into the gear tooth groove 305. While the head frame rod 302 and the rack 303 are self-locked, the arc-shaped nail plate 306 and the head nail 307 move relative to each other, thereby being synchronously inserted into the patient's head to fix the patient's head.

[0049] Among them, it needs to be supplemented that: a spring 6 is fixed between the interlayer of the arc-shaped nail plate 306 and the head frame rod 302, and between the interlayer of the head nail 307 and the head frame rod 302, respectively, and the spring 6 provides power for the reset movement of the arc-shaped nail plate 306 and the head nail 307.

[0050] Further, it is supplemented that: the ends of the two racks 303 away from the fixed head frame rod 302 are both provided with a rib 8, the length of the rib 8 is equal to the hydraulic pipe 404, and is used to limit the stroke of the rack 303.

[0051] In the above scheme, in order to further improve the function of the device, the specific operations are as follows.

[0052] Reference Figures 1 to 6 , Figures 8 to 12 In a preferred embodiment, the supporting mechanism 5 includes a connecting rod 501 rotatably connected between the support arm frame 2 and the center piece 301, a socket 502 is rotatably sleeved on the outer side of the support arm frame 2, a lower support 503 is rotatably installed on the top of the socket 502, and an upper support 504 is fixed to the side end of each of the two head frame rods 302, and the two upper supports 504 are mirror-symmetrical.

[0053] In this embodiment: the user first fixes the U-shaped support 1 to the side end of the bed, then installs the support arm 2 to the side end of the U-shaped support 1, and rotates the lower support 503, so that the lower support 503 is placed vertically and placed on the patient's neck in a U-shaped pillow, thereby assisting the user in supporting the patient's head; when the user needs to support and fix the patient's head, the user needs to rotate the U-shaped support 1, so that the U-shaped support 1 is placed horizontally, and at the same time rotate the center piece 301, so that the center piece 301 rotates around the connecting rod 501, so that the upper support 504 at the side end of the head frame rod 302 is folded upward, and aligned with the lower support 503. Figure 3 As shown; at this time, the patient has two body positions: one is lying face down between the upper support 504 and the lower support 503; the other is lying head down with the pillow placed between the upper support 504 and the lower support 503.

[0054] Among them, it is necessary to supplement that: a retention groove 505 is opened through the inside of the connecting rod 501 to provide a placement space for the folded threaded rotating rod 402; at the same time, a fixing valve 9 is provided on the outside of the connection between the center piece 301 and the connecting rod 501, and the connection between the connecting rod 501 and the center piece 301 can be fixed by rotating the fixing valve 9.

[0055] Furthermore, it is supplemented that: the lower support 503 and the upper support 504 are both made of sponge filling, and the minimum distance between the two upper supports 504 is greater than the maximum outer diameter of the lower support 503, and the sponge material can ensure the comfort of the patient when the pillow is placed.

[0056] In the above solution, in order to further improve the effect of the head nail 307 entering the patient's head, the specific operation is as follows.

[0057] Reference Fig.12 In a preferred embodiment, a thread groove 7 is provided between the head frame rod 302 and the head nail 307, and the thread groove 7 and the head nail 307 are threadedly connected.

[0058] In this embodiment, when the head nail 307 is pushed by the hydraulic pressure to move horizontally, it is also driven by the thread groove 7, so that it moves and rotates at the same time, and drills into the patient's head in a rotational manner.

[0059] Working principle: when in use, the user first fixes the U-shaped support 1 to the side end of the bed, then installs the support arm frame 2 to the side end of the U-shaped support 1, and rotates the lower support 503, so that the lower support 503 is placed vertically and placed on the patient's neck in a U-shaped pillow, thereby assisting the user to support the patient's head; thereafter, the support arm frame 2 is fixed, and the center piece 301 is installed on the side end of the support arm frame 2. After the installation is completed, the user holds the two head frame rods 302 on both sides and pulls the head frame rods 302 horizontally, so that the racks 303 located at the side ends of the head frame rods 302 move relative to each other around the meshing long gears 304, thereby adjusting the clamping range of the two head frame rods 302 until the spacing between the two head frame rods 302 is equal to the ratio of the patient's head width. At this time, the user clamps the two head frame rods 302 on both sides of the patient's head, and manually rotates the threaded rotating rod 402, so that the threaded rotating rod 402 and the piston plate 403 move toward The hydraulic chamber 401 moves inside and squeezes the liquid inside the hydraulic chamber 401, causing the liquid to be pressed toward the inside of the hydraulic pipe 404 and the hydraulic groove 405, and pressurizing the arc-shaped nail plate 306 and the head nail 307. At the same time, the moving threaded rotary rod 402 will synchronously push the long gear 304, causing the long gear 304 to move horizontally and insert into the gear tooth groove 305. While the head frame rod 302 and the rack 303 are self-locked, the arc-shaped nail plate 306 and the head nail 307 move relatively, so as to be synchronously inserted into the patient's head to fix the patient's head; when the user needs to support and fix the patient's head, the user needs to rotate the U-shaped support 1 so that the U-shaped support 1 is placed horizontally, and at the same time rotate the center piece 301 so that the center piece 301 rotates around the connecting rod 501, so that the upper support 504 at the side end of the head frame rod 302 is folded upward and aligned with the lower support 503. Figure 3 As shown; at this time, the patient has two body positions: one is lying face down between the upper support 504 and the lower support 503; the other is lying head down with the pillow placed between the upper support 504 and the lower support 503.
