Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a preoperative incision positioning device for minimally invasive spinal surgery for different fracture types. Background Technology

[0002] With the continuous advancement of medical technology, minimally invasive spinal surgery has been increasingly widely used in the treatment of spinal diseases due to its significant advantages such as less trauma, faster recovery, and fewer complications. Compared with traditional open surgery, minimally invasive spinal surgery, through smaller incisions and specialized surgical instruments, can achieve similar therapeutic effects to open surgery while reducing damage to surrounding tissues. It is particularly suitable for the treatment of various types of spinal fractures, herniated discs, spinal stenosis, and other diseases.

[0003] However, minimally invasive spinal surgery requires extremely high precision in the location of the surgical incision. Due to the limited surgical field, surgeons need to accurately locate the incision before performing the surgical procedure to avoid damaging surrounding nerves, blood vessels, and other important structures. Inaccurate incision location can not only lead to surgical failure, increasing patient suffering and surgical risks, but may also trigger a series of serious complications, such as nerve damage leading to limb paralysis or massive bleeding.

[0004] Currently, the preoperative incision localization method commonly used in minimally invasive spinal surgery in clinical practice mainly relies on traditional imaging technology. This technology can provide information on the anatomical structure of the spine, allowing doctors to initially determine the surgical site and incision location. Then, markers are attached to the patient's body surface. Doctors need to frequently travel between the device operating end and the patient to compare the preoperative images with the surface markers. On the one hand, the accuracy of incision localization is poor, and on the other hand, the efficiency of incision localization is low. At the same time, it is not convenient to locate and mark the spine for different fracture types, resulting in poor flexibility. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of inconvenience in automating the positioning of incisions in the prior art, and the low positioning efficiency and poor flexibility caused by frequent back-and-forth between the device and the patient for incision positioning.

[0043] like Figures 1 to 8 As shown, this embodiment of the invention provides a preoperative incision positioning device for minimally invasive spinal surgery for different fracture types, including a mounting box 1. A notched toothed ring 2 is slidably connected inside the mounting box 1. An adjustment mechanism 3 for adjusting the position of the notched toothed ring 2 is provided on the mounting box 1. Mounting seats 4 are fixedly connected to both ends of the notched toothed ring 2. A detector 5 is fixedly connected to the lower end face of the upper mounting seat 4, and an X-ray source 6 is fixedly connected to the upper end face of the lower mounting seat 4. A positioning mechanism 7 is provided on the upper mounting seat 4. A housing 8 is located at the rear of the mounting box 1, and an adjustment mechanism 9 for adjusting the position of the mounting box 1 is provided inside the housing 8. The mounting box 1 is... The entire device provides an installation base and support structure. The notched toothed ring 2 slides within the mounting box 1. Its sliding design allows the connected components to move flexibly within a certain range, facilitating the adjustment of the positions of the detector 5 and the X-ray source 6 to adapt to the spinal position and surgical needs of different patients. It also facilitates the acquisition of spinal images for different fracture types. The positioning mechanism 7 can emit laser pointers to the incision positioning point based on the image information, making it easier for doctors to accurately mark the incision and improve positioning accuracy. The adjustment mechanism 9 facilitates the adjustment of the position of the notched toothed ring 2, thereby facilitating the positioning of minimally invasive spinal surgical incisions for different fracture types, offering greater flexibility.

[0044] like Figure 3As shown, the adjustment mechanism 3 includes a first rotating shaft 301 rotatably disposed inside the mounting box 1. Both ends of the first rotating shaft 301 are rotatably mounted on the mounting box 1. A first gear 302, which meshes with the notched gear ring 2, is fixedly connected to the center of the first rotating shaft 301. A second gear 303 is also fixedly connected to the first rotating shaft 301. A second rotating shaft 304 is rotatably mounted inside the mounting box 1. A third gear 305, which meshes with the second gear 303, is fixedly connected to the second rotating shaft 304. A first worm gear 306 is fixedly connected to the center of the second rotating shaft 304. A mounting plate 307 is fixedly connected to the inner side wall of the mounting box 1. A first motor 308 is fixedly connected to the upper end face of the mounting plate 307. The drive end of the first motor 308 passes through the mounting plate 307 and is fixedly connected to a first worm 309, which meshes with the first worm gear 306. When it is necessary to adjust the angle between the detector 5 and the X-ray source 6, the first motor 308 is started to drive the first worm gear 309 to rotate. Since the first worm gear 309 meshes with the first worm wheel 306, it will drive the second rotating shaft 304 and the third gear 305 on the shaft to rotate synchronously. The third gear 305 meshes with the second gear 303, thereby driving the first rotating shaft 301 and the first gear 302 at the center to rotate. The first gear 302 meshes with the notched gear ring 2, and finally drives the notched gear ring 2 to rotate, realizing the angle adjustment between the detector 5 and the X-ray source 6 on the mounting seats 4 at both ends of the notched gear ring 2. At the same time, it can also drive the positioning mechanism 7 to move synchronously, thereby facilitating the positioning of the incision for minimally invasive spinal surgery for different types of fractures.

[0045] like Figures 4 to 5As shown, mechanism 7 includes a support plate 701 fixed to the side wall of the upper mounting base 4 by bolts. A first bearing 702 is mounted on the support plate 701. A rotating sleeve 703 is mounted on the inner side wall of the inner ring of the first bearing 702. A spline shaft 704 is slidably connected inside the rotating sleeve 703. A mounting frame 705 is fixedly connected to the bottom end of the spline shaft 704. A connecting shaft 706 is rotatably connected inside the mounting frame 705. A positioning frame 707 is fixedly connected to the connecting shaft 706. A laser positioning head 708 is fixedly connected to the positioning frame 707. A second worm gear 709 is fixedly connected to the center of the connecting shaft 706. An assembly plate 7010 is fixedly connected inside the mounting frame 705. A second motor 7011 is fixedly connected to the assembly plate 7010. The drive end of the second motor 7011 passes through the assembly plate 7010 and is fixedly connected to a second worm 7012 that meshes with the second worm gear 709. The second motor 7011 is started to drive the second worm gear 7012 to rotate. The second worm gear 7012 meshes with the second worm wheel 709, driving the connecting shaft 706 to rotate. The positioning frame 707 on the connecting shaft 706 and the internal laser positioning head 708 rotate synchronously with the shaft, realizing the pitch adjustment of the laser irradiation angle. The laser angle can be adjusted according to the physiological curvature of different segments of the spine (such as cervical lordosis and lumbar lordosis) to ensure that the laser mark is accurately aligned with the fracture site in the vertical direction. It is especially suitable for different types of positioning needs such as vertebral compression fractures and transverse process fractures. The laser positioning head 708 can project a light spot on the patient's skin, which makes it convenient for medical staff to accurately locate and mark the incision.

[0046] For example Figure 4 As shown, a second bearing 7013 is mounted on the top of the spline shaft 704. The inner wall of the inner ring of the second bearing 7013 is connected to the top of the spline shaft 704. A connecting plate 7014 is connected to the upper end face of the second bearing 7013. A rack 7015 is fixedly connected to the lower end face of the connecting plate 7014 away from the second bearing 7013. The bottom end of the rack 7015 passes through the support plate 701 and extends to the lower part. A fixing plate 7016 is fixedly connected to the upper end face of the support plate 701. A third motor 7017 is fixedly connected to the fixing plate 7016. The drive end of the third motor 7017 passes through the fixing plate 7016 and is fixedly connected to the rack 7015. The transmission gear 7018 is meshed with the third motor 7017, which drives the transmission gear 7018 to rotate. The transmission gear 7018 meshes with the rack 7015, pushing the connecting plate 7014 to move up and down. The connecting plate 7014 is fixed to the top of the spline shaft 704 through the second bearing 7013, thereby driving the spline shaft 704 to slide along the inside of the rotating sleeve 703, realizing the lifting and lowering of the mounting frame 705 and the laser positioning head 708, adjusting the vertical height of the laser mark. The lifting stroke is controllable and can adapt to different patient body shapes (such as differences in height and body thickness), ensuring that the laser can be accurately focused on the patient's skin surface and avoiding incision mark offset due to height deviation.

[0047] For example Figure 6 As shown, the bottom end of the rotating sleeve 703 passes through the support plate 701 and extends to the lower part. A driven gear 7019 is fixedly connected to the outer peripheral wall of the bottom of the rotating sleeve 703. A fourth motor 7020 is fixedly connected to the upper end face of the support plate 701. The driving end of the fourth motor 7020 passes through the support plate 701 and is fixedly connected to a driving gear 7021 that meshes with the driven gear 7019. When the fourth motor 7020 is started, it drives the driving gear 7021 to rotate, and the driving gear 7021 drives the driven gear 7019. The 019 rotates, which in turn drives the rotating sleeve 703 to rotate. Since the spline shaft 704 is slidably connected to the rotating sleeve 703 and can rotate synchronously, the spline shaft 704 will drive the mounting frame 705 and the laser positioning head 708 below to rotate horizontally with the rotating sleeve 703, adjusting the horizontal direction of the laser mark. It can achieve 360-degree rotation without dead angles, and can flexibly adjust the laser irradiation direction according to the fracture location (such as the left, right or central area of ​​the spine), avoiding positioning blind spots caused by equipment obstruction and improving positioning accuracy.

[0048] like Figure 2 As shown, the adjustment mechanism 9 includes a first telescopic cylinder 901 installed on the inner top wall of the housing 8. The drive end of the first telescopic cylinder 901 passes through the inner top wall of the housing 8 and is fixedly connected to an installation tube 902. A fixing plate 903 is fixedly connected inside the installation tube 902. A second telescopic cylinder 904 is fixedly connected to the inner side wall of the fixing plate 903. The drive end of the second telescopic cylinder 904 passes through the fixing plate 903 and is fixedly connected to an adjustment tube 905. The adjustment tube 905 is slidably disposed inside the installation tube 902. When the first telescopic cylinder 901 is activated, its drive end pushes the installation tube 902 to move up and down, thereby driving the installation tube 902 to facilitate the adjustment of the height of the notched toothed ring 2. When the second telescopic cylinder 904 is activated, its drive end pushes the adjustment tube 905 to slide along the inside of the installation tube 902, thereby realizing the horizontal extension and retraction of the installation box 1 and adjusting the horizontal distance between the detector 5 and the X-ray source 6 relative to the patient.

[0049] For example Figure 2 As shown, a column 10 is fixedly connected to the upper end of the chassis 8, a connecting seat 11 is fixedly connected to the top of the column 10, a fixing column 12 is fixedly connected to the outer end of the outer side wall of the connecting seat 11, and a display screen 13 is fixedly connected to the outer end of the fixing column 12. The display screen 13 is used to display the spinal image information collected by the detector 5 and the positioning information of the laser positioning head 708, which facilitates the doctor's observation and operation and improves the efficiency and accuracy of the operation.

[0050] like Figure 1As shown, a touch screen 14 is fixedly connected to the upper surface of the chassis 8. Two connecting pieces 15 are symmetrically and fixedly connected to the outer side wall of the chassis 8, and a handrail 16 is fixedly connected between the two connecting pieces 15. Doctors can input commands through the touch screen 14 to control the operation of the adjustment mechanism 3, the positioning mechanism 7 and the adjustment mechanism 9, so as to realize the automated operation of the device and improve the convenience and accuracy of the surgery.

[0051] For example Figure 1 As shown, a base plate 17 is fixedly connected to the lower end face of the chassis 8, and a set of casters 18 are installed on the lower end face of the base plate 17. The base plate 17 provides stable support for the device, and the casters 18 are installed on the lower end face of the base plate 17, which enables the device to move flexibly, making it convenient to transport and use between different operating rooms, thus improving the mobility and practicality of the device.

[0052] like Figure 2 and 3 As shown, arc-shaped sliders 19 are fixedly connected to the inner sidewalls on both sides of the mounting box 1 near the notched toothed ring 2. Arc-shaped grooves 20 that cooperate with the arc-shaped sliders 19 are provided on the front and rear sidewalls of the notched toothed ring 2. The cooperation between the arc-shaped sliders 19 and the arc-shaped grooves 20 provides guidance and limiting for the sliding of the notched toothed ring 2, ensuring the stability and accuracy of the sliding of the notched toothed ring 2, and preventing it from deviating or shaking during the sliding process.

[0053] The working process of the technical solution provided by this invention is as follows:

[0054] In use, this invention is first moved to the surgical positioning position using the handle 16 and casters 18. Then, the first telescopic cylinder 901 is activated, its drive end pushing the mounting tube 902 up and down, thereby facilitating the adjustment of the height of the notched gear ring 2. Next, the second telescopic cylinder 904 is activated, its drive end pushing the adjusting tube 905 to slide along the inside of the mounting tube 902, thus achieving horizontal telescopic movement of the mounting box 1 and adjusting the horizontal distance between the detector 5 and the X-ray source 6 relative to the patient. Then, the first motor 308 is activated, driving the first worm gear 309 to rotate. Due to the rotation of the first worm gear 309... The first worm gear 306 rotates, which in turn drives the second shaft 304 and the third gear 305 on the shaft to rotate synchronously. The third gear 305 meshes with the second gear 303, thereby driving the first shaft 301 and the first gear 302 at the center to rotate. The first gear 302 drives the notched gear ring 2 to rotate, realizing the angle adjustment of the detector 5 and X-ray source 6 on the mounting bases 4 at both ends of the notched gear ring 2, so that the detector 5 and X-ray source 6 are aligned with the patient's affected area. Then, the detector 5 and X-ray source 6 take pictures of the patient's affected area and display them on the display screen 13. The doctor then uses the image information to make the diagnosis. Then, the third motor 7017 is operated via the touch screen 14 to drive the transmission gear 7018 to rotate. The transmission gear 7018 drives the rack 7015 to move, pushing the connecting plate 7014 to move up and down. This, in turn, causes the spline shaft 704 to slide along the inside of the rotating sleeve 703, realizing the lifting and lowering of the mounting frame 705 and the laser positioning head 708, adjusting the vertical height of the laser mark. The second motor 7011 drives the second worm gear 7012 to rotate. The second worm gear 7012 meshes with the second worm wheel 709, driving the connecting shaft 706 to rotate. The positioning frame 707 on the connecting shaft 706 and the laser positioning head 708 inside rotate. 8 rotates synchronously with the shaft to achieve pitch adjustment of the laser irradiation angle. The laser positioning head 708 emits a light source to form a light spot at the patient's incision positioning point. Then, medical staff use a marker to mark the positioning point, which significantly improves the positioning accuracy. During marking, the fourth motor 7020 drives the drive gear 7021 to rotate, which in turn drives the driven gear 7019 to rotate, thereby driving the rotating sleeve 703 to rotate. The spline shaft 704 will rotate horizontally with the rotating sleeve 703, driving the mounting frame 705 below and the laser positioning head 708 to adjust the horizontal direction of the laser mark, which facilitates comprehensive positioning of the incision position.
