Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medical devices, and in particular relates to a head fixing device for neurointervention surgery. Background Art
[0002] Neurointerventional surgery is a minimally invasive surgical technique that uses catheters and other interventional devices to enter the nervous system through vascular or non-vascular pathways to diagnose and treat lesions. With the advancement of medical technology, neurointerventional surgery is increasingly being used to treat neurological problems such as cerebrovascular diseases.
[0003] During neurointerventional surgery, the patient's head is required to remain stable, because even a slight movement of the head may cause the surgical instrument to deviate from the position in the blood vessel, increasing the risk of the surgery. For example, during surgery, when the surgical instrument is operating in the blood vessel, the shaking of the head may cause the instrument to accidentally puncture the blood vessel wall. In addition, during the operation, medical staff have to spend a lot of energy to find a suitable fixation method or frequently adjust the patient's head position, so a head fixation device for neurointerventional surgery is needed. Doctors and nurses do not have to worry about the patient's head movement during the operation, and can focus more on the surgical steps and instrument operation, which helps to improve the work efficiency of the entire surgical team and reduce surgical interruptions or operational errors caused by head position problems.
[0004] However, since neurointerventional surgery usually takes a long time, if the patient's head is not well fixed, maintaining an uncomfortable posture for a long time will increase the patient's pain, and the patient will also move his head unconsciously. This device can automatically adjust back to the right position when the deviation is found, and can also help medical staff determine the direction of the patient's head deviation and make timely adjustments to avoid interference with the operation caused by head shaking; for patients, knowing that their heads have a reliable fixation device during surgery will give them a sense of security psychologically. This psychological state helps patients better cooperate with the surgery and reduce the adverse effects of tension on the surgery, such as increased blood pressure, increased heart rate and other physiological reactions, thereby indirectly improving the success rate of the surgery and the patient's satisfaction with the surgery; the stable head fixation device creates a good surgical operating environment for medical staff. Doctors and nurses do not have to worry about the patient's head movement during the operation, and can focus more on the surgical steps and instrument operation. This helps to improve the work efficiency of the entire surgical team and reduce surgical interruptions or operational errors caused by head position problems. Summary of the invention
[0005] In response to the above-mentioned problems, the present invention aims to provide a head fixation device for neurointerventional surgery, which can fix the patient's head well and help medical staff determine the deviation direction of the patient's head. When the patient's head is found to be deviated, the patient's head can be adjusted and fixed to avoid interference with the operation caused by head shaking during the operation, thereby improving the work efficiency of the entire surgical team and reducing surgical interruptions or operational errors caused by head position problems.
[0006] The main idea of the technical solution adopted by the present invention is as follows: a head fixing component and a head correction adjustment mechanism are designed on the base, and the head correction adjustment mechanism is connected to the top of the head fixing component. The head correction adjustment component can judge the deviation of the patient's head during the operation, and adjust and fix the patient's head when it is judged that the patient's head is deviated, thereby ensuring good fixation of the patient's head, and at the same time helping medical staff to judge the deviation direction of the patient's head, and can adjust and fix the patient's head when it is found that the patient's head is deviated, thereby avoiding interference of the head shaking during the operation to the operation, thereby improving the work efficiency of the entire surgical team and reducing surgical interruptions or operational errors caused by head position problems.
[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A head fixing device for neurointervention surgery, comprising a base, a head fixing component arranged on the base, and a head deviation correction adjustment mechanism; The head deviation correction adjustment mechanism is connected to the top of the head fixing component, and is used to determine the deviation of the patient's head during the operation, and to adjust and fix the patient's head when it is determined that the patient's head is deviated.

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0026] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0028] In the description of this application, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the application is usually placed when in use. They are 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 position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0030] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0031] The inventors found that during neurointerventional surgery, the patient's head must remain stable, because even a slight movement of the head may cause the surgical instrument to deviate from the position in the blood vessel, increasing the risk of surgery. For example, during surgery, when the surgical instrument is operating in the blood vessel, the shaking of the head may cause the instrument to accidentally puncture the blood vessel wall. In addition, during the operation, medical staff have to spend a lot of energy to find a suitable fixation method or frequently adjust the patient's head position, so there is a need for a head fixation device for neurointerventional surgery. Doctors and nurses do not have to worry about the patient's head movement during the operation, and can focus more on the surgical steps and instrument operation, which helps to improve the work efficiency of the entire surgical team and reduce surgical interruptions or operational errors caused by head position problems.
[0032] Based on the above findings, the present application proposes a head fixation device for neurointerventional surgery, which can fix the patient's head well, and at the same time help medical staff determine the deviation direction of the patient's head. When the patient's head is found to be deviated, the patient's head can be adjusted and fixed to avoid interference with the operation caused by head shaking during the operation, thereby improving the work efficiency of the entire surgical team and reducing surgical interruptions or operational errors caused by head position problems.
[0033] Reference Figure 1-18 As shown, a head fixation device for neurointervention surgery in an embodiment of the present application includes a base 1; A head fixing component 2 and a head deviation correction adjustment mechanism are provided on the base 1. The head deviation correction adjustment mechanism is connected to the top of the head fixing component 2. The head deviation correction adjustment mechanism is used to determine the deviation of the patient's head during the operation and adjust the patient's head when it is determined that the patient's head is deviated.
[0034] In the embodiment of the present application, a head fixing component and a head deviation correction adjustment mechanism are designed to be provided on the base, and the head deviation correction adjustment mechanism is connected to the top of the head fixing component. When the patient's head is deviated during the neurointerventional surgery, the deviation of the patient's head during the neurointerventional surgery is judged by the head deviation adjustment mechanism, and when it is judged that the patient's head is deviated, the head deviation correction adjustment structure is used to adjust and fix the patient's head, thereby ensuring that the patient's head is in the correct position during the operation, and avoiding the operation effect being affected by the movement of the head. In the present application, the fixation of the patient's head by the head fixing component and the judgment and adjustment of the head deviation correction adjustment mechanism can ensure that the patient's head is well fixed, and at the same time can help medical staff to judge the deviation direction of the patient's head, and can adjust and fix the patient's head when it is found that the patient's head is deviated, avoiding the interference of the head shaking during the operation on the operation, thereby improving the work efficiency of the entire surgical team and reducing the interruption of the operation or operation errors caused by the head position problem.
[0035] Based on the above technical solution, an "L"-shaped groove 202 is provided on the inner side of the head fixing component 2, and the "L"-shaped groove 202 is movably connected to the head adjustment component 19, and the side of the head adjustment component 19 is connected to the head correction adjustment mechanism. By controlling the head adjustment component 19 to slide in the "L"-shaped groove 202, the head correction adjustment mechanism is assisted to judge the deviation of the patient's head during the operation. When it is judged that the patient's head is deviated, the patient's head contacts the head adjustment component 19 in the "L"-shaped groove 202. During the neurointerventional surgery, the auxiliary head correction adjustment mechanism adjusts and fixes the patient's head. In the embodiment of the present application, the head adjustment component 19 is arranged in the "L"-shaped groove 202 on the inner side of the head fixing component. When the patient's head is deviated, the movement of the patient's head will drive the head adjustment component 19 in contact with the patient's head to slide in the "L"-shaped groove 202, and the position of the head adjustment component 19 will change, thereby causing the head correction adjustment mechanism connected to the head adjustment component 19 to deviate, thereby assisting the head correction adjustment mechanism to determine the deviation of the patient's head during the operation; when the head correction adjustment mechanism determines that the patient's head is deviated and the patient's head position needs to be adjusted, the head correction adjustment mechanism drives the head adjustment component to move through the adjustment of the head correction adjustment mechanism, so that the head adjustment component drives the patient's head position to return to the correct position, thereby assisting the head correction adjustment mechanism to adjust and fix the patient's head.
[0036] Based on the above technical solution, a limiting groove 201 is provided on the side of the head fixing component 2, and the head adjustment component 19 passes through the limiting groove 201 and is connected to the head correction adjustment mechanism. When the patient's head is deviated during the neurointerventional surgery, the patient's head will be driven to change the position of the head adjustment component in contact with the patient's head due to the movement of the patient's head, so that the head adjustment component 19 drives the head correction adjustment mechanism to move within the length range of the limiting groove 201, thereby assisting the head correction adjustment mechanism to judge the deviation of the patient's head during the operation; when it is determined that the patient's head is deviated and the patient's head position needs to be adjusted, the head correction adjustment mechanism drives the head adjustment component to move, thereby driving the patient's head position to return to the correct position, and assisting the head correction adjustment mechanism to adjust and fix the patient's head. On the other hand, by designing the limiting groove 201, the head adjustment component 19 drives the head correction adjustment mechanism to move within the length range of the limiting groove 201, which can provide higher rigidity and stability for the movement of the head adjustment component, ensuring that the head is well supported and fixed within the natural movement range.
[0037] In the embodiments of the present application, through the design of the head adjustment component, the head adjustment component assists the head deviation correction adjustment mechanism to determine the deviation of the patient's head during the operation, and when it is determined that the patient's head is deviated, the head deviation correction adjustment mechanism is assisted to adjust and fix the patient's head. The head adjustment component and the deviation correction adjustment mechanism are efficiently linked, so that the judgment and correction of head deviation are faster, which effectively improves the judgment accuracy and surgical efficiency of the head fixation device for neurointerventional surgery of the present application.
[0038] It should be noted that neurointerventional surgery is performed within blood vessels, and catheters, guidewires and other instruments must be accurately delivered to the target site. Even a slight deviation of the head may change the originally planned path, making it difficult for surgical instruments to accurately reach the lesion, increasing the difficulty of surgical operation, prolonging the operation time, and may even damage blood vessels or surrounding nerve tissue, affecting the effect of the operation, and increasing surgical risks and the chance of complications. In neurointerventional surgery, there is no absolutely fixed value for the impact of head deviation on the success rate of the operation. Generally speaking, a head deviation of more than 5 mm will usually have a more obvious impact on the success rate of the operation.
[0039] Optionally, the length of the limiting groove 201 in the embodiment of the present application can be set within the range of no more than 5 mm of the left and right deviation of the head adjustment component. By designing the length of the limiting groove 201 to be set within the range of no more than 5 mm of the left and right deviation of the head adjustment component, on the one hand, the shorter groove length can provide higher rigidity and stability for the movement of the head adjustment component, ensuring that the head is well supported and fixed within the natural range of movement, and on the other hand, setting the groove length within 5 mm deviation can ensure high precision of the head position, avoid excessive deviation of the patient's head, and thus improve the effect of surgery or treatment.
[0040] It should be noted that in the embodiment of the present application, the head fixing component 3 can adopt a fixing plate made of a hard material, the head adjustment component 19 can adopt an adjustment plate, the surface of the head adjustment component 19 that contacts the patient's head is made of silicone material, and the surface that contacts the head fixing component 2 is made of a hard material. The surface of the head adjustment component 19 that contacts the patient's head is made of silicone material. The silicone material has the softness and elasticity of silicone material and can provide a comfortable contact experience, reduce the patient's discomfort, and ensure the patient's comfort during use. The surface of the head adjustment component 19 that contacts the head fixation component 2 is made of hard material. Hard materials usually have a lower friction coefficient, which can ensure that when the patient's head is offset, it can slide in the "L"-shaped groove 202 on the inner side of the head fixation component 2, and drive the head correction adjustment mechanism to move, thereby assisting the head correction adjustment mechanism to determine the offset of the patient's head during the operation, and when offset occurs, the head adjustment component is displaced to drive the patient's head position to return to the correct position, thereby ensuring that the head adjustment component of the present application can assist the head correction adjustment mechanism to determine the offset of the patient's head during the operation, and when it is determined that the patient's head is offset, it assists the head correction adjustment mechanism to adjust and fix the patient's head, thereby ensuring the correction adjustment effect of the device of the present application, thereby improving the effect of the operation or treatment.
[0041] Reference Fig.10It should be noted that there is a certain gap between the side of the length direction of the head adjustment component 19 in the embodiment of the present application and the head fixing component, which is used to ensure the sliding effect of the head adjustment component 19 in the "L"-shaped groove 202 on the inner side of the head fixing component 2, and ensure that when the patient's head is offset, the head adjustment component 19 can slide in the "L"-shaped groove 202 on the inner side of the head fixing component 2, and drive the head correction adjustment mechanism to move, thereby assisting the head correction adjustment mechanism to judge the deviation of the patient's head during the operation, and when the deviation occurs, the head adjustment component is displaced to drive the patient's head position to return to the correct position, thereby ensuring that the head adjustment component of the present application can assist the head correction adjustment mechanism to judge the deviation of the patient's head during the operation, and when it is determined that the patient's head is offset, the head correction adjustment mechanism is assisted to adjust and fix the patient's head, thereby ensuring the correction adjustment effect of the device of the present application, thereby improving the effect of the operation or treatment.
[0042] Based on the above technical solution, the head deviation correction adjustment mechanism includes a deviation judgment component 15, a deviation component 5 and a deviation adjustment component 16; The deviation judgment component 15 is disposed on the rear cover plate 14 of the base 1 and is used to judge the deviation of the patient's head during the neurointerventional surgery; The offset adjustment component 16 is connected above the head adjustment component 19, and is used to adjust and fix the patient's head by controlling the offset adjustment component 16 to control the adjustment of the head adjustment component 19 when the patient's head is offset; The displacement component 5 is connected between the displacement judgment component 15 and the head adjustment component 19. The head adjustment component 19 drives the displacement component 5 to be displaced, thereby pushing the displacement judgment component 15 to move and judge the displacement degree of the patient's head.
[0043] In the embodiment of the present application, the head deviation correction adjustment mechanism is designed to include a deviation judgment component, a deviation component and a deviation adjustment component; when the patient's head is deviated, due to the movement of the head, the head adjustment component in contact with the patient's head drives the deviation component connected thereto to deviate in the corresponding direction, so that the deviation component 5 pushes the deviation judgment component 15 to be displaced, so that the state of the deviation judgment component changes, and the deviation of the patient's head is judged. When the deviation occurs, the position of the head adjustment component 19 is adjusted by the deviation adjustment component, the patient's head is adjusted, and the position of the deviation component connected thereto is driven to be adjusted, so that the state of the deviation judgment component is restored to the return state, and the correction of the patient's head position is achieved. In the present application, the mutual cooperation of the deviation judgment component, the deviation component and the deviation adjustment component can ensure the good fixation of the patient's head, and at the same time can help medical staff to judge the deviation direction of the patient's head, and can adjust and fix the patient's head when the patient's head is found to be deviated, so as to avoid the interference of the head shaking during the operation on the operation, thereby improving the work efficiency of the entire surgical team and reducing the interruption of the operation or operation errors caused by the head position problem.
[0044] Based on the above technical solution, in the embodiment of the present application, the offset component 5 includes a "T"-shaped limiting rod 52 and a telescopic rod 51 which is sleeved with the vertical end of the "T"-shaped limiting rod 52. The end surface of the horizontal end of the "T"-shaped limiting rod 52 is arranged below the offset judgment component 15. The head adjustment component 19 is clamped at the end of the telescopic rod 51, and is used to adjust the head adjustment component 19 through the offset adjustment component (16) to achieve position adjustment of the offset component 5, so that the position of the offset judgment component (15) is restored to its original state.
[0045] In the embodiment of the present application, the offset component 5 is designed to include a "T"-shaped limiting rod 52 and a telescopic rod 51 sleeved with the "T"-shaped limiting rod 52. During use, when the patient's head position is offset, the head adjustment component 19 moves with the telescopic rod 51 to the side of the head offset, so that the horizontal end of the "T"-shaped limiting rod 52 disposed below the offset judgment component 15 is correspondingly offset, and then the position of the offset judgment component 15 on the offset side is changed, thereby helping the surgeon or nurse to judge the offset direction of the patient's head during the operation, so that the surgeon or nurse can promptly detect the offset of the patient's head, and adjust and fix the patient's head position according to the relative offset, so as to avoid the interference of head shaking during the operation on the operation, thereby improving the work efficiency of the entire surgical team and reducing surgical interruptions or operational errors caused by head position problems.
[0046] In some embodiments, the end surface of the horizontal end of the "T"-shaped limiting rod 52 is an inclined structure, and the end surface of the horizontal end of the "T"-shaped limiting rod (52) pushes the displacement judgment component (15) in the corresponding displacement direction to deflect, so as to judge the displacement degree of the patient's head. By designing the end surface of the horizontal end of the "T"-shaped limiting rod 52 to be an inclined structure, when the patient's head deflects during the neurointerventional surgery, the displacement adjustment component 16 moves with the telescopic rod 51 to the side of the displacement, and the horizontal end of the "T"-shaped limiting rod 52 moves to the side of the displacement, so that the "T"-shaped limiting rod 52 pushes the displacement judgment component in the corresponding displacement direction to jump out, so that the doctor or nurse can timely find that the patient's head has deflected, and the end surface of the horizontal end of the "T"-shaped limiting rod 52 is designed to be an inclined structure. The inclined structure can effectively transmit force and control movement, so that the "T"-shaped limiting rod 52 can accurately push out the corresponding displacement judgment component, thereby achieving accurate guidance and positioning, and improving the stability and accuracy of the head fixing device of the present application.
[0047] The end of the offset judgment component 15 is spherical. By designing the end of the offset judgment component 15 to be spherical, when the patient's head is offset during neurointerventional surgery, the offset judgment component 15 in the corresponding offset direction is pushed to jump upward. The spherical offset judgment component 15 and the "T"-shaped limiting rod 52 with a trapezoidal structure at the horizontal end cooperate with each other to form a stable support structure, which is convenient for precise position control and direction adjustment, prevents the offset judgment component 15 from offsetting or loosening during movement, reduces motion errors, improves the judgment accuracy of the offset judgment component 15, and significantly improves the performance and reliability of the device of the present application.
[0048] In some embodiments, the offset adjustment component 16 includes a first micro motor 161 and a return rotation rod 162 connected to the first micro motor 161, and the return rotation rod 162 is connected to the head adjustment component 19, and is used to control the return rotation rod 162 through the first micro motor 161 to push the head adjustment component 19 when the patient's head is offset, so as to adjust and fix the patient's head. In the embodiment of the present application, when the patient's head is offset, the return rotation rod 162 is controlled by the first micro motor 161, and the movement of the return rotation rod pushes the head adjustment component 19 to move, so that the head adjustment component 19 drives the patient's head position to return to the correct position, so as to adjust and fix the patient's head. At the same time, the head adjustment component 19 moves the telescopic rod 51, drives the "T"-shaped limiting rod 52 to return to the correct position, so that the pushed-out offset judgment component 15 is returned, and the patient's head is readjusted and fixed, so as to adjust and fix the patient's head in time when the patient's head is offset.
[0049] In some embodiments, the first micromotor 161 is provided with a fixed angle, and the fixed angle is the angle of the motor when the patient's head is in the return state. In the embodiment of the present application, by setting a corresponding angle for the first micromotor 161, that is, the angle set by the first micromotor 161, that is, the angle of the first micromotor when the patient's head is in the return state (that is, the patient's head has not deviated and is in the correct position required for the interventional surgery) during the neurointerventional surgery, when the patient's head is offset, the head adjustment component (19) drives the telescopic rod 51 to deviate, so that the return rotation rod 162 connected to the head adjustment component (19) rotates, and the angle of the first micromotor 161 changes the offset setting angle. At this time, since the first micromotor deviates from the set angle, the motor rotates back to the original state, thereby realizing the adjustment and fixing of the patient's head by controlling the rotation rod to rotate through the first micromotor, so that the offset head is automatically corrected by the first micromotor, and the automatic adjustment of the head offset is realized.
[0050] In the above technical solution, the head adjustment component 19 is connected to the return rotation rod 162 through the connection column 191 provided thereon. When the patient's head is deviated, the first micro motor controls the return rotation rod to rotate, thereby driving the connection column 191 to move left and right, and adjusting and fixing the patient's head, so that the first micro motor drives the return rotation rod to rotate to correct the deviated head, thereby realizing automatic adjustment of the head deviation.
[0051] In the above technical solution, the return rotation rod 162 is connected to the motor 161 through the motor slot 164 provided thereon, and the other end of the return rotation rod 162 is provided with a movable slot 163, and the connecting column 191 is movably connected to the movable slot 163. When the patient's head is deviated, the first micro motor controls the return rotation rod to rotate, thereby driving the connecting column 191 to slide in the movable slot 163, thereby realizing the left and right movement of the connecting column 191, and then realizing the movement of the connecting column driven by the return rotation rod to adjust and fix the patient's head, so that the first micro motor drives the return rotation rod to rotate to correct the deviated head, and realizes the adjustment of the head deviation.

By designing that the base is also provided with a neck support adjustment component 3 and a mandibular fixing component 4, when fixing the patient's head, the use of the neck support adjustment component 3 and the mandibular fixing component 4 can more effectively fix the patient's head, reduce accidents caused by head movement during surgery, improve the safety of surgery, help doctors perform precise operations during surgery, and improve the success rate and effect of surgery.
