Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to an arthroscopic surgical navigation and positioning device. Background Technology
[0002] Arthroscopic surgery is a minimally invasive procedure performed on a joint. An endoscope is inserted into the joint through a small incision, and orthopedic surgeons use video images transmitted through the endoscope to examine and treat the joint. Current arthroscopic surgery mainly uses an outside-in approach, inserting a syringe needle, removing the needle, and then using a scalpel to make an incision in the skin based on the needle's position to create an access path. An expansion channel is then created within the skin, and after stabilizing the channel, the endoscope is inserted into the channel for subsequent examination and treatment. However, the existing method has the problem of the channel closing after the scalpel has created the channel and then the endoscope is inserted. This makes it difficult for the surgeon to make accurate positioning and also makes subsequent operations inconvenient. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide an arthroscopic surgical navigation and positioning device, which solves the problem of inaccurate navigation and positioning in arthroscopic surgery after the channel is established in the prior art.
[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0005] An arthroscopic surgical navigation and positioning device includes a housing, an incision mechanism, a visualization mechanism, and a control mechanism. The incision mechanism penetrates the housing. The visualization mechanism is built into the interior of the housing and can extend to the exterior of the housing. The control mechanism is connected to the visualization mechanism. In use, the incision mechanism cuts open the patient's skin, and the housing extends into the tissue through the incision to form a surgical channel. The control mechanism controls the extension and retraction of the visualization mechanism within the surgical channel, thereby achieving precise navigation and positioning of the visualization mechanism during the surgical process.
[0006] In the above scheme, the control mechanism includes a gear assembly, a main control board, and a gyroscope. The gyroscope and the gear assembly are both connected to the main control board. The gear assembly is also connected in cooperation with the visualization mechanism.
[0007] In the above scheme, the gear assembly includes a first gear, a second gear, and a connecting belt. The first gear is connected to the second gear through the connecting belt. The first gear is also connected to the main control board. The second gear is connected to the visualization mechanism. When the main control board controls the first gear to rotate, it drives the second gear to rotate through the connecting belt, thereby causing the visualization mechanism to extend and retract along the axis.
[0008] In the above scheme, the control mechanism also includes a power supply component, and the first gear, the main control board, and the gyroscope are all connected to the power supply component.
[0009] In the above scheme, the gear assembly, the main control board, and the power supply component are all housed within the outer casing.
[0010] In the above scheme, the visualization mechanism includes a panoramic camera and a cable group, with the panoramic camera located at one end of the cable group; the cable group is connected to the second gear.
[0011] In the above scheme, the cable assembly is provided with teeth for engaging with the second gear.
[0012] In the above scheme, a cable channel is also provided inside the outer casing, and the cable group is disposed in the cable channel.
[0013] In the above scheme, the control mechanism also includes a power supply component, and the gear assembly, the main control board and the gyroscope are all connected to the power supply component.
[0014] In the above scheme, a slit channel is also provided inside the outer shell, and the slit mechanism passes through the slit channel; a water injection channel is also provided on the side wall of the outer shell, and the water injection channel is connected to the slit channel; when water needs to be injected, the slit mechanism moves away from the slit channel, and water is injected through the water injection channel.
[0015] In the above scheme, the head end of the outer shell is flat.
[0016] In the above solution, the outer casing is also provided with buttons and a joystick, both of which are connected to the main control board.
[0017] Compared with existing technologies, this invention features an incision mechanism that penetrates the outer shell, with a visualization mechanism built into the shell and extending to the outside. The control mechanism is also connected to the visualization mechanism. The outer shell, through the incision in the patient's skin, forms a surgical channel, allowing the control mechanism to guide the visualization mechanism through this channel into the tissue, thus achieving precise navigation and positioning during the surgery. This invention solves the problem of inaccurate navigation and positioning after establishing a channel in arthroscopic surgery; it eliminates the need for repeated insertion of the visualization device after channel establishment; and its simple structure, low cost, and suitability for clinical use make it ideal for this invention.

[0025] Example
[0026] This utility model provides an arthroscopic surgical navigation and positioning device, see [link to relevant documentation]. Figures 1 to 3The device includes an outer shell 1, an incision mechanism 2, a visualization mechanism 3, and a control mechanism 4. The incision mechanism 2 penetrates the outer shell 1. The visualization mechanism 3 is built into the interior of the outer shell 1 and can extend to the exterior of the outer shell 1. The control mechanism 4 is connected to the visualization mechanism 3. In use, the incision mechanism 2 cuts open the patient's skin, and the outer shell 1 extends into the tissue through the incision to form a surgical channel. The control mechanism 4 controls the visualization mechanism 3 to extend and retract within the surgical channel, thereby achieving precise navigation and positioning of the visualization mechanism 3 during the surgical process.
[0027] By adopting the above solution, this utility model, through the incision mechanism 2 penetrating the outer shell 1 and embedding the visualization mechanism 3 inside the outer shell 1, which can extend to the outside of the outer shell 1, and connecting the control mechanism 4 to the visualization mechanism 3, forms a surgical channel through the patient's skin cut by the incision mechanism 2 in the outer shell 1. This allows the control mechanism 4 to control the visualization mechanism 3 to penetrate deep into the tissue through the surgical channel, thereby achieving precise navigation and positioning during the surgical process. This utility model can solve the problem of inaccurate navigation and positioning during arthroscopic surgery when establishing the channel; this utility model eliminates the need for repeated insertion of the visualization device after the channel is established; this utility model has a simple structure, low cost, and is suitable for clinical use.

Both the gyroscope 43 and the gear assembly 41 are connected to the main control board 42. The gear assembly 41 is also connected to the visualization mechanism 3. The gear assembly 41 drives the visualization mechanism 3 to extend and retract along its axis. The main control board 42 controls the gear assembly 41 and the gyroscope 43.

The second gear 412 is connected to the visualization mechanism 3. When the main control board 42 controls the first gear 411 to rotate, it drives the second gear 412 to rotate via the connecting belt 413, thereby causing the visualization mechanism 3 to extend and retract along the axis. The first gear 411 engages with the second gear 412 via the connecting belt 413, and the first gear 411 drives the second gear 412 to rotate, thereby causing the visualization mechanism 3 to extend and retract along the axis of the outer shell 1.

[0033] See Figures 1 to 3 In a specific implementation of this utility model embodiment, the visualization mechanism 3 further includes a panoramic camera 31 and a cable assembly 32.

[0034] Furthermore, in this embodiment, the panoramic camera 31 is a 360° panoramic camera, which can capture panoramic images inside the joint cavity.
[0035] In a specific implementation of this utility model embodiment, the cable assembly 32 is further provided with teeth 321 for engaging with the second gear 412. When the second gear 412 rotates, the teeth 321 mesh with the second gear 412, causing the cable assembly 32 and the panoramic camera to extend and retract along the axis of the housing 1.
[0036] In a specific implementation of this utility model embodiment, a cable channel is further provided inside the outer casing 1, and the cable group 32 is disposed inside the cable channel.

[0045] See Figures 1 to 3 First, the incision mechanism 2 is used to cut the skin at the patient's joint. The flat end of the outer shell 1 is then inserted into the patient's skin through the incision to form a surgical channel, which is stopped at an appropriate depth. The incision mechanism 2 is then pulled out through the incision channel 11, and water is injected into the joint through the water injection channel 12. Next, the user operates the buttons on the outer shell 1 to start the control mechanism 4. The main control board 42 controls the first gear 411 to start rotating, which drives the second gear 412 to rotate through the connecting belt 413. The second gear 412 engages with the teeth 321 on the cable assembly 32 to adjust the position of the cable assembly 32 and the panoramic camera 31. Finally, the angle of the image is adjusted by the joystick to complete the navigation and positioning process.
[0046] In summary, this invention achieves precise navigation and positioning during surgery by extending the incision mechanism 2 through the incision channel 11 and embedding the visualization mechanism 3 inside the outer shell 1, which can also extend to the outside of the outer shell 1. Furthermore, the gear assembly 41 is connected to the visualization mechanism 3. The outer shell 1, through the incision of the patient's skin by the incision mechanism 2, forms a surgical channel. This allows the gear assembly 41 to control the visualization mechanism 3 to penetrate deep into the tissue via the surgical channel, thereby achieving precise navigation and positioning during the surgical process. Additionally, this invention utilizes a gyroscope 43 and a joystick to adjust the angle of the image, facilitating user operation. This invention solves the problem of inaccurate navigation and positioning after establishing a channel in arthroscopic surgery; it eliminates the need for repeated insertion of the visualization device after channel establishment; and its simple structure, low cost, and suitability for clinical use make it ideal for this invention.
