Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a non-invasive, visual cranial depression corrector. Background Technology

[0002] Depressed skull fractures often result in a ping-pong ball-shaped depression in the head and are a common clinical condition in neurosurgery. The traditional treatment involves making an incision in the scalp at the edge of the depression, retracting the incision, drilling a hole in the skull, and then inserting a bone skid or hemostat through the bone hole to pry up the depressed fracture portion from outside the dura mater. The scalp is then sutured. This procedure leaves a bone hole in the skull and a permanent scar on the scalp.

[0003] Treatment of skull fractures or congenital depressions in newborns often requires craniotomy. Because children's skulls are thinner, more elastic, and less rigid, the incidence of fractures is higher than in adults. Among pediatric skull fractures, depressed fractures are relatively common, accounting for about one-third. Furthermore, due to the anatomical and physiological characteristics of the pediatric skull, and the differences in the magnitude, speed, and direction of external forces and the size of the contact surface with the skull, different types of depressed fractures appear clinically. When the external force is slow and the contact surface with the skull is small, type I depressed fractures often occur, clinically without brain injury or with only minor brain injury, and with visible and obvious depression. When the external force is large and fast, and the contact surface is large, type II depressed fractures often occur, with multiple fracture lines and multiple bone fragments showing conical or ring-shaped depressions on X-rays and during surgery, making reduction difficult. Local scalp hematoma and periosteal separation are also common. When the external force is too strong, the speed is too fast, and the contact area is too small, bone fragments or external force directly cause open damage to the meninges and brain (Type III). Clinically, brain tissue can be seen spilling out of the wound, and bone fragments and foreign bodies remain in the brain, resulting in severe local contamination and more severe and complex clinical symptoms. If bone fragments cause damage to the meninges and cerebral blood vessels, it forms a Type IV depressed fracture. The hematoma is often consistent with the fracture site, and clinically, focal symptoms such as hemiplegia are more common.

[0004] Treatment options for depressed skull fractures in children: One view is that depressed skull fractures in infants can spontaneously reduce due to increased intracranial pressure when crying; another view is that children's brains develop rapidly, and during this period all depressed skull fractures should be surgically reduced, otherwise it will affect the child's brain development and lead to epileptic foci.

[0005] Currently, a positive attitude should be taken towards depressed skull fractures in children. The absolute and relative values ​​of the subarachnoid space in children are smaller than those in adults (the difference between brain volume and cranial cavity capacity). In newborns, it is only about 2.5%, from the first week to 6 years old about 3%, and increases significantly after 6 years of age until the free space value reaches relative stability in adolescence. The average free space in adults is 7.5%, significantly higher than in children.

[0006] Therefore, when a child's depressed fracture has a depression greater than 0.5 cm, surgery should be performed as soon as possible. In particular, in cases of conical depression and comminuted impacted depression, spontaneous reduction is almost impossible, and surgical reduction is the only option.

[0007] The treatment methods for different types of fractures are as follows: ① Type I fracture: Usually, under local anesthesia, a simple reduction method is used to reposition the cone-shaped fracture fragment to the normal curvature of the inner table. ② Type II fracture: Because bone fragments are impacted or embedded in the brain, complete reduction is difficult. The reduction method should be selected according to the situation, and bone fragments should not be easily discarded. During surgery, attention should be paid to the consistent reduction of the inner and outer bone plates to prevent the omission of the depression of the inner table. ③ Type III and IV fractures: Due to the complexity of the condition, craniotomy with bone flap or bone window is required under general anesthesia. When treating Type III fractures, liquefied brain tissue and foreign bodies should be thoroughly removed. At the same time, attention should be paid to finding bone fragments and comparing them with preoperative X-ray films. The wound tract should be repeatedly irrigated with hydrogen peroxide solution and antibiotic solution to repair meningeal defects. Bone fragments can also achieve satisfactory results by treating them according to the aforementioned methods. For Type IV fractures, the focus is on thorough hemostasis. Different reduction methods can be selected as appropriate.

[0008] However, regardless of the type of fracture, any surgical treatment involved places a significant financial and psychological burden on the patient's family, especially for newborns. Craniotomy causes pain and can severely impact an infant's growth and development. There are also cases where craniotomy can be avoided, such as congenital depression of the skull in infants with no or only minor brain injury, but a visible and obvious depression. In these cases, craniotomy is unnecessary; the depression can be corrected using tools. For example, a non-surgical reduction device can be used: this device consists of a wing nut, a screw, three legs and an integrated leg fixation base, and a reduction support or hook. Designers use this device to treat depressed skull fractures in children. However, these tools are complex in design. Post-operatively, the tightening of the screws creates blind spots for cleaning and disinfection, potentially leading to incomplete cleaning, disinfection, and sterilization, increasing the risk of post-operative infection. Furthermore, multiple people are required for operation, resulting in relatively low efficiency. Therefore, widespread adoption is not recommended.

[0009] A constant-pressure lifting-type visual reduction device for depressed skull fractures, with publication number (CN 112603505 A), includes a first reduction rod and a second reduction rod. The first and second reduction rods are combined to form an L-shaped reduction rod. A coupling plate is connected to the first reduction rod, and a pressure nut is threadedly connected to the top of the first reduction rod at the coupling plate. A display screen is installed on the first reduction rod, and an arc-shaped reduction head is fitted onto the end of the second reduction rod away from the first reduction rod. This invention breaks with traditional surgical reduction methods for depressed skull fractures, inventing a novel visual surgical reduction device that enables precise surgical reduction. The unique shape of the arc-shaped reduction head is similar to the morphology of the skull surface, and its unique telescopic structure facilitates reaching the distal fracture area. The L-shaped reduction rod rotates horizontally under visual guidance, allowing adjustment of the arc-shaped reduction head's horizontal position, which is beneficial for precise reduction.

[0010] However, the L-shaped reduction rod in this application only rotates horizontally under visual guidance and does not have a 360-degree visual rotation part that can be driven to rotate by airflow from the airbag. Therefore, this application is not convenient for observing the internal surgical situation from multiple angles. Furthermore, this application does not have a three-level craniotomy correction part that can adjust the negative pressure suction on the cranial depression in a progressive manner, thereby facilitating pressure control and adjustment during surgery and further improving the surgical effect and accuracy. Therefore, it is impossible to achieve multi-level control and adjustment of pressure during surgery. Summary of the Invention

[0011] To address the aforementioned problems, this invention aims to provide a non-invasive, visual craniotomy device, which features a 360-degree visual rotating part driven by air jets from an airbag, providing excellent visibility; furthermore, it includes a three-stage craniotomy correction part that allows for progressive adjustment of the negative pressure suction applied to the craniotomy depression, thereby further improving surgical effectiveness and accuracy.

[0012] The main idea of ​​the technical solution adopted in this invention is as follows: Depressed skull fracture is one of the common diseases in neurosurgery. Since the depressed bone fragment may damage or compress brain tissue and affect its function, surgical treatment is often required. Patients with intracranial hematoma should have surgery as soon as possible. However, there are also cases where recovery can be achieved without craniotomy. For example, in infants with congenital depressed skull fracture, if there is no brain injury or only a minor brain injury, and there is a visible and obvious depression, craniotomy is not required. Recovery can be achieved simply by using a depression correction tool. As an example, a reduction tool that can be used to correct depression without craniotomy is a sling reduction device: This reduction device consists of a wing nut, a screw, three legs and an integrated leg fixing base, and a reduction support or hook. The designer uses this reduction device to treat depressed skull fractures in children. However, these tools are complex in design, and during postoperative instrument handling, there are blind spots for cleaning and disinfection due to the tightened screw threads, which may lead to incomplete cleaning, disinfection and sterilization and cause postoperative infection risks. They also require multiple people to cooperate and have relatively low work efficiency, so they are not conducive to promotion.

[0013] Currently, there are also publicly available devices for visually reducing cranial depressions, but these devices are not convenient for multi-angle observation of the internal surgical situation, therefore: ① Considering that the current craniotomy device cannot accurately judge the effect of the operation from multiple angles in real time during the operation, this application designs a visualization structure with 360-degree rotation to monitor the operation process in all directions, observe the operation effect at all times, and adjust the operation. ② The pressure of current cranial depression correctors is difficult to control precisely and smoothly, which may lead to over-operation; therefore, this application designs a three-level negative pressure control system, which can be manually fine-tuned after the required pressure value is reached, to further improve the effect and accuracy. ③During the correction process, it is difficult to quickly switch to a suitable suction cup for different degrees and sizes of skull deformation, resulting in poor adaptability. Therefore, this application designs an interface with replaceable suction cups, which can quickly replace the appropriate suction cup according to the patient's actual situation.

[0014] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A non-invasive, visual craniotomy device for correcting craniotomy depression includes a negative pressure suction rod and a craniotomy depression correction device located on the negative pressure suction rod. A transparent silicone suction cup is provided below the negative pressure suction rod. The device is characterized by: The cranial depression correction device includes a three-stage cranial depression correction unit and a pneumatic 360-degree visual rotating unit connected thereto. The pneumatic 360-degree visible rotating part includes a pneumatic structure and a rotating structure linked thereto, and the rotating structure is provided with a visible component. The three-stage cranial depression correction unit includes a first-stage pressure regulating structure with a vacuum pumping component, a second-stage pressure regulating structure with an adjustment component, and a third-stage pressure regulating structure with a strain pressure regulating component.

[0015] Furthermore, the pneumatic structure includes a gas generating component mounted on the negative pressure suction rod and a gas channel located below and connected to the gas generating component.

[0016] Furthermore, the rotating structure includes a rotating blade located below the gas channel and a rotating frame located below and connected to the rotating blade.

[0017] Furthermore, the visual components include a light source and a camera located on the rotating frame.

[0018] Furthermore, the first-stage pressure regulating structure includes a vacuum pumping component vertically connected to the pneumatic structure and a control component connected to the vacuum pumping component.

[0019] Furthermore, the vacuum assembly includes a negative pressure balloon and a negative pressure channel connected thereto.

[0020] Furthermore, the control component is a control valve located on the negative pressure channel.

[0021] Furthermore, the second-stage pressure regulating structure includes an adjusting component located inside the negative pressure suction rod and a handwheel located outside the negative pressure suction rod and connected to the adjusting component. The adjusting component is a lead screw piston rod connected to the handwheel.

[0022] Furthermore, the third-stage pressure regulating structure includes a strain-regulating pressure regulating component and a buffer component located below the lead screw piston rod. The strain-regulating pressure regulating component includes a hollow frustum that matches the inner diameter of the negative pressure suction rod, and a solid disk located below and connected to the frustum.

[0023] Furthermore, the buffer assembly is a flexible material buffer pad located below and connected to the disk.

[0024] The beneficial effects of this invention are: compared with the prior art, the improvement of this invention lies in that... Both the suction cup base and the rotating frame in this application are made of transparent material, which facilitates clear image transmission from the lighting and camera. During craniotomy, not only can clear images be transmitted through the lighting and camera, but the airbag can also be squeezed simultaneously to blow air onto the impeller. The gripping force can be controlled according to the required field of vision, so that the airflow is ejected from the nozzle as needed, causing the rotating blade to adjust its angle and drive the camera to rotate around the suction cup base. This allows for multi-angle observation of the internal surgical situation and provides guidance for the next step of the operation. This application features a three-stage craniotomy correction system: a first-stage pressure-adjusting structure that evacuates the suction rod to prepare for subsequent suction; a second-stage pressure-adjusting structure that uses a handwheel to control the rise and fall of the lead screw piston when the suction reaches a certain value, altering the sealed space within the suction rod and adjusting the negative pressure for precise manual control and better surgical results; and a third-stage pressure-adjusting structure that, after the craniotomy is corrected and greater suction is applied, allows a solid disc connected to a sponge buffer pad to move upwards, further reducing the negative pressure channel and thus decreasing the suction force to prevent over-correction. This three-stage pressure-adjusting structure progressively adjusts the negative suction applied to the craniotomy depression, facilitating pressure control and adjustment during surgery, and further improving surgical outcomes, safety, and accuracy.

[0025] The cranial depression corrector proposed in this application is non-invasive and less painful because it does not require craniotomy. It reduces the economic and psychological burden on patients and their families, and will not cause surgical pain to newborns or affect their growth and development. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] In the description of this application, it should be noted that the terms "center," "upper," "lower," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0045] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] Depressed skull fractures are a common neurosurgical condition. Because the depressed bone fragments can damage or compress brain tissue, affecting its function, they often require prompt craniotomy. Patients with intracranial hematomas require even more urgent surgery. However, there are cases where craniotomy can be performed without it. For example, in infants with congenital depressed skull fractures, where there is no clinical brain injury or only minor brain injury, and a visible and obvious depression, craniotomy is unnecessary. Reduction can be achieved using tools to correct the depression. As an example, a non-surgical tool for depression correction is the sling reduction device: this device consists of a wing nut, a screw, three legs and an integrated leg fixation base, and a reduction support or hook. Designers use this device to treat depressed skull fractures in children. However, this type of tool is complex in design. Post-operatively, the tightening of the screw creates blind spots for cleaning and disinfection, potentially leading to incomplete cleaning, disinfection, and sterilization, increasing the risk of post-operative infection. Furthermore, it requires multiple people to operate, resulting in relatively low efficiency. Therefore, its widespread adoption is limited.

[0047] Therefore, in order to address the shortcomings of existing craniotomy devices, this application discloses a non-invasive, visual craniotomy device. For details, please refer to [link to specific structure]. Figures 1-12 And the textual description of this application.

[0048] This application discloses a non-invasive visual cranial depression corrector, which includes a negative pressure suction rod and a cranial depression correction device located on the negative pressure suction rod. A transparent silicone suction cup 7 is provided below the negative pressure suction rod 11. The transparent silicone suction cup 7 is threadedly connected to the suction cup seat 10 located on the negative pressure suction rod 11. Furthermore, the transparent silicone suction cup 7 is available in various sizes, which can be selected according to the cranial depression of different patients. It can be quickly assembled and disassembled with the suction cup seat 10, and is also convenient for postoperative cleaning and disinfection.

[0049] The craniotomy device includes a three-stage craniotomy correction unit and a pneumatic 360-degree visual rotating unit connected to it. The pneumatic 360-degree visible rotating part includes a pneumatic structure and a rotating structure linked to it, with a visible component on the rotating structure. The pneumatic structure includes a gas generating component mounted on a negative pressure suction rod and a gas channel located below and connected to the gas generating component. It should be noted that the gas generating component in this application is an airbag 4, and the gas channel located below and connected to the airbag 4 is a nozzle 5. The airbag 4 has an air inlet and a nozzle 5 at its bottom; when the airbag 4 is pressed, gas is ejected from the nozzle 5.

[0050] The rotating structure includes a rotating blade 9 located below the nozzle 5 and a rotating frame 6 located below the rotating blade 9 and connected to it via a connecting rod 13. The rotating frame 6 is a rotatable hollow frustum with the same shape as the hollow frustum 16, fitted around the outside of the frustum 16. The rotating frame 6 is made of transparent silicone and has three holes, in which two lights 15 and a camera 14 are respectively fixed. When the airbag 4 is pressed, the airflow from the nozzle 5 sprays onto the blades of the rotating blade 9 and causes them to rotate. The rotating blade 9 then drives the rotating frame 6 to rotate, which in turn drives the lights 15 and the camera 14 to rotate, facilitating multi-angle observation of the internal surgical situation.

[0051] In use, press the airbag 4 to expel gas from the nozzle 5 and drive the rotating blade 9 to rotate. The surface of the airbag 4 is integrally molded with textured surfaces to facilitate gripping and squeezing. The surgical operator can control the gripping force according to the required field of vision, so that the airflow is ejected from the nozzle 5 as needed, causing the rotating blade 9 to drive the rotating frame 6 to adjust the angle. This allows the camera 14 on the rotating frame 6 to observe the surgical effect from all angles, providing guidance for the next step of the operation.

[0052] More specifically, both the suction cup mount 10 and the rotating bracket 6 are made of transparent silicone material, which facilitates the illumination of the light lamp 15 and the transmission of clear images by the camera 14.

[0053] The three-stage cranial depression correction unit of this application includes a first-stage pressure regulating structure with a vacuum pumping component, a second-stage pressure regulating structure with an adjustment component, and a third-stage pressure regulating structure with a strain pressure regulating component.

[0054] The first-stage pressure regulating structure includes a vacuum pumping assembly perpendicularly connected to the pneumatic structure and a control assembly connected to the vacuum pumping assembly. The vacuum pumping assembly includes a negative pressure balloon 1 and a negative pressure channel 8 connected to it. The control assembly is a control valve 2 located on the negative pressure channel, used to control the amount of negative pressure provided by the negative pressure balloon 1 to the negative pressure suction rod 11.

[0055] The second-stage pressure regulating structure includes an adjustment component located inside the negative pressure suction rod 11 and a handwheel 3 located outside the negative pressure suction rod 11 and connected to the adjustment component. The adjustment component is a lead screw piston rod 12 connected to the handwheel 3.

[0056] It should be noted that the negative pressure balloon 1 used in this application is an existing product, model XHB008. During use, after the transparent silicone suction cup 7 is fixed in place, the negative pressure balloon 1 is used to generate sufficient negative pressure within the negative pressure suction rod 11. Under the sealing effect between the transparent silicone suction cup 7 and the skull, the concave portion is corrected outward by the suction force of the transparent silicone suction cup 7. When the suction force reaches a certain value, the control valve 2 is closed, and the handwheel 3 is used to rotate and control the rise and fall of the lead screw piston rod 12, changing the sealed space within the negative pressure suction rod 11, thereby adjusting the negative pressure within the negative pressure suction rod 11, allowing for precise and controllable manual operation to achieve better surgical results.

[0057] The third-stage pressure regulating structure includes a strain gauge pressure regulating component and a buffer component located below the lead screw piston rod 12. The strain gauge pressure regulating component includes a hollow frustum 16 that matches the inner diameter of the negative pressure suction rod 11, and a solid disc 20 located below the frustum 16 and connected to it via three elastic rubber pillars 17. The buffer component is a flexible material buffer pad located below and connected to the disc 20. There are many types of flexible materials, which will not be listed here. As an example, the flexible material used in this application is sponge, and the buffer pad is a sponge buffer pad 19.

[0058] When subjected to strong suction, the three elastic columns 17 bend and contract, causing the disc 20 to move upward within the negative pressure suction rod 11, reducing the size of the pressure channel within the negative pressure suction rod 11. When skull depression is corrected, contact with the sponge cushioning pad 19 also causes the disc 20 to move upward, further reducing the pressure channel and thus reducing the force of the negative pressure suction. This avoids over-suction and over-correction. Example 1

[0059] To address the shortcomings of existing craniotomy devices, this application discloses a non-invasive, visual craniotomy device. In use, a suitable transparent silicone suction cup 7 is first selected based on the specific craniotomy condition of the patient. The suction cup 7 is then placed on the craniotomy site. The negative pressure balloon 1 is then pressed, creating a vacuum environment in the suction rod 11. Under the sealing effect between the transparent silicone suction cup 7 and the skull, the depressed area is corrected outward by the suction force of the suction cup 7. When the suction force reaches a certain value, the control valve 2 is closed. Simultaneously, the airbag 4 is pressed, causing gas to be expelled from the nozzle 5 and rotating the rotating blade 9. The surface of the airbag 4 is integrally formed with textured surfaces for easy gripping and compression. The surgical operator can control the gripping force according to the required field of vision, allowing airflow to be ejected from the nozzle 5 as needed. This causes the rotating blade 9 to adjust the angle of the rotating frame 6, facilitating comprehensive observation of the surgical effect by the camera 14 on the rotating frame 6, monitoring the craniotomy deformation at any time, and providing guidance for subsequent procedures. Example 2

[0060] The usage process and method of this embodiment are the same as those of Embodiment 1. The difference is that while using the transparent silicone suction cup to correct the skull depression, the surgical effect can be observed from all angles through the camera 14 on the rotating frame 6. While observing, the surgical operator can use the second-stage pressure regulating structure of this application, that is, use the handwheel 3 to rotate and control the rise and fall of the lead screw piston rod 12, change the sealed space inside the negative pressure suction rod 11, and thus adjust the negative pressure inside the negative pressure suction rod 11 to perform precise and controllable manual operation to achieve better surgical results. Example 3

[0061] The usage process and method in this embodiment are the same as in Embodiment 1. The difference is that, when subjected to greater suction, the surgical operator can adjust the pressure on the cranial depression by using the strain-adjusting pressure regulating component and buffer component of the third-stage pressure regulating structure of this application. During adjustment, the three elastic columns 17 bend and contract, causing the disc 20 to move upward inside the negative pressure suction rod 11, reducing the size of the pressure channel within the negative pressure suction rod 11. When the cranial depression is corrected, contact with the sponge buffer pad 19 will also cause the disc 20 to move upward, further reducing the pressure channel and thus reducing the force of negative pressure suction. This avoids over-suction and over-correction.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
