Description

Technical Field

[0001] The present invention relates to the field of postoperative skull fracture repair assistance, and more particularly to a neurosurgery clinical postoperative skull fracture repair assistance device. Background Art

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

[0003] After a patient undergoes craniotomy, a repair assist device is usually used to protect the patient's head to prevent secondary injury to the patient's head during postoperative recovery. However, existing repair assist devices are usually adapted for use and cannot be used for patients with a variety of different head sizes. When used on patients who do not fit the device, there is a problem of loose fixation, which has certain limitations. After the existing repair assist device is worn on the patient's head and protects it, medical staff need to manually remove it each time they apply medicine. During the disassembly and assembly process, if the medical staff is not careful, the patient's wound area may be touched, causing pain to the patient or causing further damage to the wound, affecting the healing process. At the same time, manual removal and reinstallation of the repair assist device will increase the workload of medical staff and reduce nursing efficiency, especially in some cases that require frequent dressing changes or treatments, which will consume a lot of time and energy. For this reason, we provide a neurosurgery clinical postoperative skull fracture repair assist device to solve the above problems. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention aims to provide an auxiliary device for postoperative skull fracture repair in neurosurgery.

[0010] Optionally, the connecting component includes a fixed plate installed at the bottom of the plurality of bonding plates, the bottom of the fixed plate is rotatably connected to a limiting shaft, one end of the limiting shaft passes through the outside of the fixed plate and is fixedly connected to the bonding plate, and a torsion spring is installed between the inner side of the limiting shaft and the fixed plate.

[0011] Optionally, the toggle assembly includes an abutment plate slidably connected to the inside of the U-shaped plate, an inclined surface is provided on the inner side of the abutment plate, the bottom of the abutment plate is connected to the inner bottom of the U-shaped plate through a third spring, an abutment block is installed inside the limiting groove, two connecting rods are installed on the outer wall of the abutment block, a sliding groove matching the two connecting rods is opened inside the limiting groove, and the limiting groove is slidably connected to the two connecting rods through sliding grooves opened on both sides.

[0012] Optionally, the switching assistant includes connecting plates installed on both sides of the arc-shaped frame, one side of the connecting plate is fixedly connected to the fixing seat, the fixing seat nut is connected to the screw, and two fixing grooves matching the fixing seat are opened on the top of the U-shaped plate, and the U-shaped plate is movably connected to the fixing seat through the two fixing grooves opened on the top.

[0013] Optionally, the switching assist device also includes two worm gears rotatably connected to the top of the connecting plate, fixed shafts are rotatably connected to both sides of the arc frame, the fixed shafts are fixedly connected to a worm wheel meshing with the worm gears, and an adjustment unit for adjusting the position of the protective cover is installed between the connecting plate and the protective cover.

[0014] Optionally, the adjusting unit includes a wedge block fixedly connected to the top of the connecting plate, the outer wall of the fixed shaft is located on one side of the wedge block and is fixedly connected to a rotating plate, a rebound groove is provided on the inner side of the rotating plate, moving blocks are installed on both sides of the protective cover, and the moving blocks are slidably connected to the inner side of the rebound groove, a fourth spring is installed between the moving block and the rebound groove, and an abutting shaft is installed on the end face of the protective cover, and the abutting shaft initially abuts on the inclined surface of the wedge block.

[0015] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0016] In the above scheme, by setting up a clamping mechanism, after the craniotomy of the patient, the medical staff will bandage the wound, and the medical staff can insert the U-shaped plate below the craniotomy site, so that after the U-shaped plate is inserted into the patient's head position, it can be fitted on the patient's skull through multiple fitting plates on the rectangular plate. When the rectangular plate encounters resistance during the process of fitting on the patient's head, it can adaptively push the column rod to slide inwardly of the ball shaft, so that the rectangular plate and multiple fitting plates can be adaptively clamped according to the different skull shapes of the patient, thereby improving the overall practicality of the device.

[0017] By cooperating with the provided abutment plates and other parts, the screw contacts the abutment plates while being screwed in, and the abutment plates can be pushed during the screwing process. At this time, the abutment plates move toward the bottom of the U-shaped plate to squeeze the third spring. When the inclined surface on the inner side of the abutment plate contacts the inclined surface at the end of the abutment block during the movement of the abutment plate, the abutment block is pushed to drive the circular plate toward the patient's head under the action of the abutment plate, so that the multiple fitting plates on the rectangular plate can continue to move toward the patient's head, thereby further tightening the plate, thereby improving the fixing effect between the U-shaped plate and the patient's head.

[0018] Through the cooperation of the provided fitting plates and other parts, when the fitting plates fit the patient's head, the fitting plates can automatically and adaptively rotate when encountering resistance. Since the limiting shaft at the connection of each fitting plate rotates inside the fixed plate, the maximum rotation angle can reach degrees. When the limiting shaft rotates, the torsion spring works, and then each fitting plate slowly expands outward according to the shape of the patient's head until it fits the patient's head, so that the fitting plate can fit the patient's head shape to a certain extent. Since the clamping in the prior art simply clamps the more protruding parts of the patient's head, the patient may collide or rub more during use, which may easily cause the device to shift, thereby affecting its protective effect. Because the above can further improve the fixing effect between the U-shaped plate and the patient's head.

[0019] Through the cooperation of the worm and other parts, when the patient's wound is regularly applied with medicine, the medical staff can first manually rotate the worm, thereby driving the worm gear to drive the rotating plate to rotate, and then the protective cover can be rotated away from the patient's head, so as to realize the protective cover opening operation. When the protective cover is opened, it can be in a tilted state, so that the medical staff can apply medicine to the head covered by the protective cover. Since there are two protective covers symmetrically, the medical staff can close the protective cover after applying medicine to one side and open the other protective cover to apply medicine again. If the application range is relatively large and both protective covers block the medical staff during the application process, the screw can be operated to release the arc frame and it can be removed. There is no need for the staff to separate the entire device from the patient, thereby improving the overall practicality of the device.

[0020] Through the cooperation of the wedge block and other parts, when the protective cover rotates, the abutment shaft rod rotates along the inclined surface of the wedge block. Under the action of the inclined surface of the wedge block, the abutment shaft rod is pushed to drive the protective cover to move laterally, so that the curvature of the protective cover can be increased during the rotation process, making it easier for the staff to open a larger range for the application operation, thereby providing convenience for the staff to apply the medicine.

[0040] like Figures 1 to 10As shown, an embodiment of the present invention provides a neurosurgery clinical postoperative skull fracture repair auxiliary device, comprising: the U-shaped plate 1, the interior of the U-shaped plate 1 is provided with a plurality of the limiting grooves 2 that penetrate to the inner side of the U-shaped plate 1, the arc frame 3 is installed above the U-shaped plate 1, the top of the arc frame 3 is installed with two the protective covers 4, and the interior of the U-shaped plate 1 is provided with a plurality of the circular plates 5; a clamping mechanism is located inside the U-shaped plate 1, and is used to fix the U-shaped plate 1 on the head of the craniotomy patient; the clamping mechanism includes four the pillar rods 6 installed in a circular array on the side wall of the circular plate 5, the interior of the U-shaped plate 1 is provided with a slot matching the four the pillar rods 6, and each the pillar rod 6 is slidably connected to the interior of the slot, one end of each the pillar rod 6 is installed with a first spring 7, one end of the first spring 7 is installed inside the slot, the interior of the circular plate 5 is installed with the ball shaft 8, and the clamping mechanism also includes an opening A sliding groove is provided on the inner side of the ball shaft 8, and the column rod 2 10 is slidably connected inside the sliding groove, and a second spring 9 is installed between the column rod 2 10 and the sliding groove, and the rectangular plate 11 is installed at one end of the column rod 2, and a plurality of mutually combined fitting plates 12 are installed on both sides of the rectangular plate 11. The inner side of the U-shaped plate 1 is provided with a toggle assembly for pushing the circular plate 5 to move, and the toggle assembly includes the abutment plate 16 slidably connected to the inside of the U-shaped plate 1, and the inner side of the abutment plate 16 is provided with an inclined surface, and the bottom of the abutment plate 16 is connected to the inner bottom of the U-shaped plate 1 through the third spring 17, and the inside of the limiting groove 2 is provided with the abutment block 18, and the outer wall of the abutment block 18 is provided with two connecting rods 19, and the interior of the limiting groove 2 is provided with a sliding groove matching the two connecting rods 19, and the limiting groove 2 is slidably connected with the two connecting rods 19 through the sliding grooves opened on both sides.

[0041] Elastic rubber pads are installed on the inner sides of the rectangular plate 11 and the multiple bonding plates 12 to protect the patient's head after bonding. After the craniotomy of the patient, the medical staff will bandage the wound, and the medical staff can insert the U-shaped plate 1 below the craniotomy site, so that after the U-shaped plate 1 is inserted into the patient's head position, it can be bonded to the patient's skull through the multiple bonding plates 12 on the rectangular plate 11. When the rectangular plate 11 encounters resistance during the process of bonding to the patient's head, it can adaptively push the column rod 2 10 to slide inwardly of the ball shaft 8, so that the rectangular plate 11 and the multiple bonding plates 12 can be adaptively clamped according to the different skull shapes of the patient, thereby improving the overall practicality of the device.

[0042] When the U-shaped plate 1 is initially adaptively stuck on the patient's head, the medical staff can then place the protective cover 4 on the arc frame 3 on the U-shaped plate 1, and at the same time align the fixing seats 21 on both sides of the arc frame 3 with the fixing grooves on the U-shaped plate 1 and insert them, and then screw the screw 22 into the fixing seat 21 until it is screwed into the inside of the U-shaped plate 1, thereby fixing the arc frame 3 on the U-shaped plate 1 through the fixing seat 21 and the connecting plate 20. At this time, the protective cover 4 can protect the entire head of the craniotomy patient.

[0043] When the screw 22 is screwed in, it contacts the abutment plate 16, and can push the abutment plate 16 during the screwing-in process. At this time, the abutment plate 16 moves toward the bottom of the U-shaped plate 1 to squeeze the third spring 17. When the inner inclined surface of the abutment plate 16 contacts the end inclined surface of the abutment block 18 during the movement of the abutment plate 16, the abutment block 18 is pushed under the action of the abutment plate 16 to drive the circular plate 5 to move toward the patient's head, so that the multiple fitting plates 12 on the rectangular plate 11 can continue to move toward the patient's head, thereby performing further compression, thereby improving the fixing effect between the U-shaped plate 1 and the patient's head.

[0044] like Figure 6 and Figure 7 As shown, the multiple bonding plates 12 are connected by connecting components, and the connecting components include the fixed plate 13 installed at the bottom of the multiple bonding plates 12. The bottom of the fixed plate 13 is rotatably connected to the limiting shaft 14, and one end of the limiting shaft 14 passes through the outside of the fixed plate 13 and is fixedly connected to the bonding plate 12. The torsion spring 15 is installed between the inner side of the limiting shaft 14 and the fixed plate 13.

[0045] During the process of the fitting plate 12 fitting the patient's head, the fitting plate 12 can automatically and adaptively rotate when encountering resistance. Since the limiting shaft 14 at the connection of each of the fitting plates 12 rotates inside the fixing plate 13, the maximum rotation angle can reach 90 degrees. When the limiting shaft 14 rotates, the torsion spring 15 works, and then each of the fitting plates 12 slowly expands outward according to the shape of the patient's head until it fits the patient's head, so that the fitting plate 12 can fit the patient's head shape to a certain extent. Since the clamping in the prior art simply clamps the more protruding parts of the patient's head, the patient may collide or rub more during use, which may easily cause the device to shift, thereby affecting its protective effect. Because the above can further improve the fixing effect between the U-shaped plate 1 and the patient's head.

[0046] like Figure 3 、 Figure 8 and Figure 10 As shown, the switching assistant includes the connecting plate 20 installed on both sides of the arc frame 3, one side of the connecting plate 20 is fixedly connected to the fixing seat 21, the fixing seat 21 is nut connected to the screw 22, and the top of the U-shaped plate 1 is provided with two fixing grooves matching the fixing seat 21, and the U-shaped plate 1 is movably connected to the fixing seat 21 through the two fixing grooves opened on the top. The switching assistant also includes the two worms 23 rotatably connected to the top of the connecting plate 20, and the two sides of the arc frame 3 are rotatably connected to the fixed shaft 24, and the fixed shaft 24 is fixedly connected with the worm wheel 25 meshing with the worm 23.

[0047] When the patient's wound is regularly coated with medicine, the medical staff can first manually rotate the worm 23 to drive the worm gear 25 to drive the rotating plate 26 to rotate, so that the protective cover 4 can be rotated away from the patient's head, thereby realizing the opening operation of the protective cover 4. When the protective cover 4 is opened, it can be in a tilted state to facilitate the medical staff to apply medicine to the head covered by the protective cover 4. Since there are two protective covers 4 symmetrically arranged, the medical staff can close the protective cover 4 after applying medicine to one side and open the other protective cover 4 to apply medicine again. If the coating range is relatively large and both protective covers 4 block the medical staff during the coating process, the screw 22 can be operated to release the arc frame 3 and remove it. There is no need for the staff to separate the entire device from the patient, thereby improving the practicality of the entire device.

[0048] like Figures 1 to 3 、 Figure 8 and Figure 9 As shown, an adjustment unit for adjusting the position of the protective cover 4 is installed between the connecting plate 20 and the protective cover 4, and the adjustment unit includes the wedge block 27 fixedly connected to the top of the connecting plate 20, and the outer wall of the fixed shaft 24 is located on one side of the wedge block 27 and is fixedly connected to the rotating plate 26, and the inner side of the rotating plate 26 is provided with the rebound groove 31, and the moving blocks 28 are installed on both sides of the protective cover 4, and the moving blocks 28 are slidably connected to the inner side of the rebound groove 31, and the fourth spring 29 is installed between the moving block 28 and the rebound groove 31, and the end face of the protective cover 4 is installed with the abutting shaft 30, and the abutting shaft 30 initially abuts on the inclined surface of the wedge block 27.

[0049] When the protective cover 4 rotates, the abutment shaft 30 rotates along the inclined surface of the wedge block 27. Under the action of the inclined surface of the wedge block 27, the abutment shaft 30 is pushed to drive the protective cover 4 to move laterally, so that the curvature of the protective cover 4 can be increased during the rotation process, so that the staff can open a larger range for the application operation, thereby providing convenience for the staff to apply the medicine.

[0050] The working process provided by the technical solution of the present invention is as follows:

[0051] First, after the craniotomy is performed on the patient, the medical staff will bandage the wound. The medical staff can insert the U-shaped plate 1 below the craniotomy site, so that after the U-shaped plate 1 is inserted into the patient's head, it can be fitted on the patient's skull through the multiple fitting plates 12 on the rectangular plate 11. When the rectangular plate 11 encounters resistance during the process of fitting on the patient's head, it can adaptively push the column rod 2 10 to slide inwardly of the ball shaft 8, so that the rectangular plate 11 and the multiple fitting plates 12 can be adaptively clamped according to the different skull shapes of the patient.

[0052] During use, when the U-shaped plate 1 is initially adaptively stuck on the patient's head, the medical staff can then place the protective cover 4 on the arc frame 3 on the U-shaped plate 1, and at the same time align the fixing seats 21 on both sides of the arc frame 3 with the fixing grooves on the U-shaped plate 1, and then screw the screw 22 into the fixing seat 21 until it is screwed into the inside of the U-shaped plate 1, thereby fixing the arc frame 3 on the U-shaped plate 1 through the fixing seat 21 and the connecting plate 20. At this time, the protective cover 4 can protect the entire head of the craniotomy patient.

[0053] Then, when the screw 22 is screwed in, it contacts the abutment plate 16, and the abutment plate 16 can be pushed during the screwing process. At this time, the abutment plate 16 moves toward the bottom of the U-shaped plate 1 to squeeze the third spring 17. During the movement of the abutment plate 16, when the inner inclined surface contacts the end inclined surface of the abutment block 18, the abutment block 18 is pushed under the action of the abutment plate 16 to drive the circular plate 5 to move toward the patient's head, so that the multiple fitting plates 12 on the rectangular plate 11 can continue to move toward the patient's head, thereby causing further tightening.

[0054] While the fitting plate 12 fits the patient's head, the fitting plate 12 can automatically and adaptively rotate when encountering resistance. Since the limiting shaft 14 at the connection of each fitting plate 12 rotates inside the fixed plate 13, the maximum rotation angle can reach 90 degrees. When the limiting shaft 14 rotates, the torsion spring 15 works, and then each fitting plate 12 slowly expands outward according to the shape of the patient's head until it fits the patient's head, so that the fitting plate 12 can fit the shape of the patient's head to a certain extent.

[0055] When applying medicine to the patient's wound regularly, the medical staff can first manually rotate the worm 23 to drive the worm gear 25 to drive the rotating plate 26 to rotate, so that the protective cover 4 can be rotated away from the patient's head, thereby realizing the opening operation of the protective cover 4. When the protective cover 4 is opened, it can be in a tilted state, so that the medical staff can apply medicine to the head covered by the protective cover 4. Since there are two protective covers 4 symmetrically, the medical staff can close the protective cover 4 after applying medicine to one side and open the other protective cover 4 to apply medicine again. If the application range is relatively large and both protective covers 4 block the medical staff during the application process, the screw 22 can be operated to release the arc frame 3 and it can be removed without the staff having to separate the entire device from the patient.

[0056] When the protective cover 4 rotates, the abutment shaft 30 rotates along the inclined surface of the wedge block 27. Under the action of the inclined surface of the wedge block 27, the abutment shaft 30 is pushed to drive the protective cover 4 to move laterally, so that the curvature of the protective cover 4 can be increased during the rotation process, making it easier for the staff to open a larger range for the application operation, thereby providing convenience for the staff to apply the medicine.

To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.
