Description

Technical Field

[0001] The present invention relates to medical device technology, and in particular to an adaptive and adjustable neurosurgery stereotactic surgery precise positioning device. Background Art

[0002] The stereotactic head frame is a basic tool commonly used in minimally invasive neurosurgery and is widely used in the treatment of non-functional neurological diseases. The greatest feature of traditional stereotactic head frames is their high positioning accuracy, which can often reach the submillimeter level. However, the disadvantage of traditional brain stereotactic head frames is also very obvious: they are cumbersome to operate. During clinical implementation, doctors need to fix the metal stereotactic head frame with a ruler to the patient's head using four large, dedicated head pins. During the fixation process, at least two doctors need to work closely together to complete a series of operations such as head frame adjustment, local anesthesia, and head pin fixation, which consumes a lot of manpower and time. The accurate installation of the stereotactic head frame often directly determines the success of the operation, and the accuracy of the stereotactic head frame installation has a significant impact on the insertion point of the puncture needle.

[0003] A Chinese invention patent with publication number CN116999187A discloses a stereotactic device, which uses a base to fix the stereotactic device to the head. The connector and the base are detachably connected, so that the patient can remove the connector from the base before the CT scanning operation is completed, which can reduce the weight on the patient's head. The connector is pivoted on the base so that the connector can rotate relative to the base, which can increase the working range of the stereotactic device. The guide rail and the connector are ball-jointed so that the guide rail can swing flexibly relative to the connector, which can further increase the flexibility and working range of the stereotactic device. The guide is mounted to the slide rail through a bracket, and the guide can move relative to the slide rail, which can further increase the flexibility and working range of the stereotactic device and facilitate accurate, flexible and rapid positioning of the puncture operation. The stereotactic device has a simple structure, is easy to use and has low cost.

[0004] Existing equipment provides a single adjustment method during use, which limits the patient's comfort, making it impossible to reduce the patient's burden during the installation process, and making it difficult for medical staff to install the stereotactic head frame. At the same time, the entire device is restricted to the patient's head. Due to the different positions of the support points, the overall weight cannot be evenly distributed, resulting in excessive pressure on a certain part, which in turn causes pressure on the patient's body. Therefore, an adaptive and adjustable neurosurgical stereotactic surgical precision positioning device has been developed. Summary of the Invention

Therefore, they should not be understood as limiting the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, unless otherwise expressly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium, or they can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Example: See Figures 1-8 An adaptive and adjustable neurosurgical stereotactic surgical precision positioning device includes a fixing plate 1, and a support plate 11 is fixedly installed at the end of the fixing plate 1 to support the patient's head through the support plate 11.

[0038] In this solution, a flexible plate is provided on the inner wall of the support plate 11, which contacts the patient's head through the flexible plate to reduce the burden of the fixed plate 1 on the patient. At the same time, screws and other telescopic adjustment components are provided between each support plate 11 to facilitate the adjustment of the distance between two adjacent support plates 11, making it suitable for different scenarios.

[0039] Furthermore, positioning rods 12 are fixedly installed on both sides of the fixed plate 1, and positioning blocks 13 are slidably installed on the outer surface of the positioning rods 12. The ends of the positioning blocks 13 are fixedly installed with arc plates 14, and the outer surface of the arc plates 14 is slidably installed with arc sleeve plates 15.

[0040] Specifically, the positioning block 13 is limited by two positioning rods 12, and a movable track is provided for the movement of the positioning block 13. A screw or other fixing component is provided on one side of the positioning block 13, and the positioning block 13 is locked by the screw after it moves to the appropriate position.

[0041] The arc sleeve 15 is slidably installed on the arc plate 14. The position of the arc sleeve 15 is adjusted according to actual needs to make it suitable for different scenarios. In addition, screws and other locking components are provided on the back of the arc sleeve 15 to fix the moved arc sleeve 15.

[0042] Furthermore, the adjustment component 2 is assembled at the end of the arc sleeve 15, and performs preliminary adjustment following the arc sleeve 15, and performs fine adjustment through the adjustment component 2; wherein, the adjustment component 2 includes a fixed block 21 fixedly connected to the arc sleeve 15, and two splints 22 are fixedly installed at the end of the fixed block 21, and a telescopic part 221 is fixedly installed between the two splints 22, and a slot 222 is opened at the end of the splint 22.

[0043] In this embodiment, the telescopic member 221 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the telescopic member 221 is started, it synchronously drives the splint 22 set at its output end to move until the splint 22 tightly locks the ball 23.

[0044] The end of the fixing block 21 is provided with a plurality of bolts, and the fixing block 21 is locked on the arc-shaped sleeve plate 15 by the bolts, and moves synchronously with the arc-shaped sleeve plate 15 .

[0045] When the arc-shaped sleeve plate 15 is adjusted in position, the adjustment component 2 arranged at its end is simultaneously driven to move until it moves to a roughly appropriate position and then stops; then the internal mechanism of the adjustment component 2 is slightly adjusted until it meets the current needs.

[0046] Furthermore, a sphere 23 is rotatably mounted on the inner wall of the slot 222, and a telescopic rod 231 is fixedly mounted on the outer surface of the sphere 23. An adjustment plate 27 is fixedly mounted on the end of the telescopic rod 231, and a guide cylinder 28 is fixedly mounted on the end of the adjustment plate 27, so that the component can be precisely positioned through the guide cylinder 28.

[0047] Specifically, the telescopic rod 231 is composed of a cylinder and a round rod, and the outer surface of the round rod is slidably connected to the inner wall of the cylinder. The length of the telescopic rod 231 is adjusted according to actual conditions to make it suitable for different scenarios.

[0048] When the telescopic rod 231 rotates around the sphere 23, the adjustment plate 27 fixedly installed at the end of the telescopic rod 231 is synchronously driven to move, thereby driving the guide cylinder 28 fixedly installed on the adjustment plate 27 to move. Personalized adjustments can be made according to the patient's specific needs, treatment site, condition and other factors to meet the different needs of different patients.

[0049] Furthermore, an arc-shaped groove 24 is formed at the end of the fixing block 21 , an arc-shaped block 241 is slidably mounted on the inner wall of the arc-shaped groove 24 , and a limit block 25 is fixedly mounted on the end of the arc-shaped block 241 .

[0050] Specifically, the arc block 241 moves, driving the limit block 25 fixedly installed at its end to move synchronously. At the same time, a baffle is fixedly installed on one side of the arc groove 24 to protect the arc block 241.

[0051] When the sphere 23 is moved by force, the telescopic rod 231 is driven to drive the movable block 26 to move. Since the outer surface of the movable block 26 is slidably mounted on the inner wall of the limit groove 252, the limit block 25 moves synchronously with the telescopic rod 231. At the same time, the limit block 25 is fixedly mounted on the arc block 241, so that when the limit block 25 moves, it cooperates with the arc block 241 to move on the inner wall of the arc groove 24.

[0052] Furthermore, the end of the limit block 25 is provided with a through hole 251, and the inner wall of the through hole 251 is provided with a limit slot 252, and the inner wall of the limit slot 252 is slidably mounted with a movable block 26. The end of the telescopic rod 231 passes through and extends to the outside of the movable block 26, and the end of the movable block 26 is fixedly mounted with a drive rod 261, and the end of the drive rod 261 is fixedly connected to the inner wall of the through hole 251.

[0053] Specifically, the driving rod 261 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the driving rod 261 is started, it synchronously drives the movable block 26 fixedly installed at its output end to move.

[0054] The outer surfaces of both ends of the movable block 26 are slidably connected to the inner wall of the limiting groove 252 , so that when the movable block 26 is moved by force, the movable block 26 is driven to move along the inner wall of the limiting groove 252 .

[0055] At the same time, a hole is opened at the end of the movable block 26, which limits the telescopic rod 231, so that when the movable block 26 moves, the telescopic rod 231 drives the ball 23 to rotate on the inner wall of the slot 222 until it reaches the optimal position and stops.

[0056] A limiting groove is provided at the end of the movable block 26, and the inner wall of the limiting groove is rotatably connected to the outer surface of the telescopic rod 231, so that when the movable block 26 moves, the telescopic rod 231 rotates around the sphere 23 until it reaches the optimal position and stops.

[0057] Furthermore, a protective block 29 is fixedly installed on one side of the fixed block 21, a power piece 291 is fixedly installed on the end of the protective block 29, a power rod 292 is fixedly installed on the output end of the power piece 291, and the end of the power rod 292 is slidably connected to the end of the arc block 241.

[0058] Specifically, the power piece 291 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the power piece 291 is started, it synchronously drives the power rod 292 fixedly installed at its output end to move. Since the end of the power rod 292 is slidingly connected to the end of the arc block 241, when the power rod 292 is forced to move, the arc block 241 is driven to move along the inner wall of the arc groove 24, thereby realizing the angle adjustment of the adjustment plate 27, ensuring that it can be finely positioned and adjusted according to the individual differences and needs of the patient.

[0059] Furthermore, the lifting assembly 3 is assembled on both sides of the fixed plate 1, and the components installed on the fixed plate 1 are auxiliary supported by the lifting assembly 3; the lifting assembly 3 includes a docking block 31 that is clamped with the fixed plate 1, and a docking hole 311 is provided at the end of the docking block 31, and a receiving groove 32 is provided at the end of the docking block 31 away from the docking hole 311.

[0060] In this embodiment, the inner wall of the docking hole 311 is provided with a fixing member such as a bolt, by which the docking block 31 is fixedly mounted on the fixing plate 1. At the same time, the suction cup 38 is stored in the storage groove 32, so that the space occupied is reduced when it is subsequently collected.

[0061] Furthermore, a first clamping block 33 is rotatably mounted on the end of the docking block 31 , a second clamping block 331 is rotatably mounted on one side of the first clamping block 33 , and a flip plate 35 is rotatably mounted on the end of the second clamping block 331 .

[0062] Specifically, the flip plate 35 is connected to the docking block 31 through the first clamping block 33 and the second clamping block 331 , and the flip plate 35 can be quickly stored.

[0063] Furthermore, a second protective rod 341 is rotatably mounted on the end of the first clamping block 33, and the end of the second protective rod 341 is rotatably connected to the end of the flip plate 35; a first protective rod 34 is rotatably mounted on the end of the second clamping block 331, and the end of the first protective rod 34 is rotatably connected to the end of the docking block 31.

[0064] Specifically, the first securing rod 34 and the second securing rod 341 define the first securing block 33 and the second securing block 331 , so that when the docking block 31 and the flip plate 35 rotate to the maximum angle, the entirety remains stable.

[0065] Furthermore, an adjustment slot 36 is formed at the end of the flip plate 35, and an adjustment block 37 is rotatably mounted on the inner wall of the adjustment slot 36. A suction cup 38 is fixedly mounted on the end of the adjustment block 37, and the lifting assembly 3 is limited by the suction cup 38.

[0066] Specifically, an adjustable support column is provided at the lower end of the adjustment block 37, and the suction cup 38 is adjusted in conjunction with the support column, so that after the lifting component 3 is flipped to the maximum angle, the suction cup 38 is driven to retract and retract by the support column until the suction cup 38 contacts the panel and stops, so that the suction cup 38 is adsorbed on the panel to support and stabilize the entire stereotactic device, ensure that its weight is evenly distributed, avoid excessive pressure on a certain part, and reduce pressure on the patient's body.

[0067] The control device can use a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (MCU), consisting of an arithmetic unit, a controller, memory, and input / output devices, equivalent to a miniature computer. Compared to the general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its greatest advantages are its small size, allowing it to be placed inside the instrument, low memory capacity, simple input / output interfaces, and low functional consumption.

[0068] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
