Description

Technical Field

[0001] This invention relates to the field of surgical instruments, specifically a combined neuroendoscopic surgical instrument. Background Technology

[0002] Neuroendoscopic surgery is a minimally invasive surgical procedure. The operating space is small, requiring a high degree of precision in instruments and maneuverability. Clinical procedures typically involve multiple steps, including suction and debridement, hemostasis, cutting, clamping, dissection, curettage, biopsy, and dilation. Traditional methods require the use of multiple independent instruments in alternation, making the procedure cumbersome.

[0003] Traditional neuroendoscopic surgical instruments are single-function, requiring frequent instrument changes and multiple insertions and exits through the endoscopic portal. This not only prolongs the operation time but also increases the risk of damage to brain tissue, nerves, and blood vessels. Alternating use of multiple instruments can lead to intermittent and unclear exposure of the surgical field, affecting surgical stability and safety. Furthermore, using multiple independent instruments increases surgical preparation and management costs, complicates the operational steps, and hinders the surgeon from maintaining a continuous and stable surgical rhythm. The inability to integrate multiple functional instruments and achieve continuous single-handed operation makes it difficult to meet the clinical needs for efficient and safe minimally invasive neuroendoscopic surgery.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example

[0028] Please see Figures 1-6 This is a schematic diagram of some embodiments of a combined neuroendoscopic surgical instrument used in this application.

[0029] Example 1

[0030] In some embodiments, the modular neuroendoscopic surgical instruments can be used in minimally invasive neuroendoscopic surgeries, including but not limited to intracranial hematoma evacuation, intracranial tumor resection, cerebral vascular malformation surgery, cisterns separation, hydrocephalus drainage, brain tissue lesion biopsy, and meningeal repair. Figure 1 In this embodiment, the application of a combined neuroendoscopic surgical instrument in neuroendoscopic intracranial tumor resection is used as an example. Other neuroendoscopic surgical scenarios can use the same or similar structures, which will not be described in detail below.

[0031] It is understood that the attached diagram only schematically shows the core components of the combined neuroendoscopic surgical instrument, and the actual shape, size, installation position and relative structure of each component are not limited by the attached diagram; the instrument can also be equipped with auxiliary components such as anti-slip structure, sealing structure, interface component, and limiting structure according to clinical needs.

[0032] In some embodiments, the combined neuroendoscopic surgical instrument comprises a suction body assembly 1, an individual item adjustment assembly 2, a drive unit 3, and a recall unit 4. The suction body assembly 1 is the basic main body of the instrument, used to provide negative pressure suction and support the other components; multiple sets of individual item adjustment assemblies 2 are arranged around the outside of the suction body assembly 1, used to realize the folding out and retraction of functional items; the drive unit 3 is located on the upper side of the suction body assembly 1, used to provide driving power for the individual item adjustment assemblies 2; the recall unit 4 is located in the middle of the suction body assembly 1, used to realize the single selection switching and positioning recall of different functional items, avoiding structural interference caused by multiple items extending at the same time.

[0033] For example, this device may also include a central suction channel, insulating wiring, a miniature inflatable catheter, a return spring 27, a sealing gasket, a standard interface, and other structures to meet the integrated operation requirements of suction, hemostasis, cutting, clamping, scraping, biopsy, dilation, ablation, and peeling.

[0034] In some embodiments, the suction device body assembly 1 includes a suction rod 11, a central negative pressure suction channel, and a placement slot 12. The suction rod 11 is made of medical-grade 316L stainless steel with a polished surface, has a diameter of 2.0–5.0 mm, and an overall length of 200–250 mm. It is compatible with standard neuroendoscopic channel sizes, does not obstruct the endoscopic view, and can withstand high-pressure steam sterilization at 134°C.

[0035] The suction rod 11 has a central negative pressure suction channel with an inner diameter of 1.5–5.0 mm, which is used for continuous suction of blood, cerebrospinal fluid, tissue debris, etc. during surgery. The tail is equipped with a standard Luer interface, which can be directly connected to the negative pressure suction host in the operating room.

[0036] Eight placement slots 12 are evenly opened circumferentially on the outer side of the suction rod 11. The depth of the placement slots 12 is 0.2–0.4 mm, and they are respectively used to store eight single product bodies 21 with different functions. In the retracted state, the single product body 21 is completely embedded in the placement slot 12, flush with the outer wall of the rod, without protrusions or sharp edges, so as to avoid scratching the surrounding tissue when entering and exiting the endoscope channel.

[0037] It should be noted that the number of placement slots 12 corresponds one-to-one with the number of individual product bodies 21. This embodiment takes an eight-group circumferential arrangement as an example; in other embodiments, it can be set to four groups, six groups, ten groups, etc., according to surgical needs, as long as it can achieve individual product storage and circumferential distribution.

[0038] Understandably, the diameter, length, depth and spacing of the suction rod 11, the placement groove 12 and the attached figure are only schematic. The specific parameters can be adjusted according to the endoscope channel specifications and operational requirements, and are not limited here.

[0039] In some embodiments, eight sets of single-item adjustment components 2 are provided, each corresponding to one of eight placement slots 12. Each set of single-item adjustment components 2 has the same structure, except for the end working end. The single-item adjustment component 2 includes a single-item body 21, a rotating shaft 22, a gear 23, a rack 24, a transmission slide rod 25, a drive rod 26, and a return spring 27.

[0040] One end of the single-item body 21 is fixedly connected to the rotating shaft 22, which is rotatably connected to the inner wall of the placement groove 12, allowing the single-item body 21 to deflect and fold around the rotating shaft 22. A gear 23 is fixedly sleeved on the outside of the rotating shaft 22, and a rack 24 is meshed below the gear 23, sliding back and forth along the inner wall of the suction rod 11. One end of the transmission slide rod 25 is fixedly connected to the rack 24, and the other end is fixedly connected to the drive rod 26. The transmission slide rod 25 slides through and is slidably connected within a pre-set guide groove inside the suction rod 11, achieving linear guiding motion.

[0041] The reset spring 27 is sleeved on the outside of the transmission slide bar 25, and its two ends are fixedly connected to the lower end face of the drive rod 26 and the inner wall of the suction rod 11, respectively, to provide reset pull force so that the single product body 21 automatically retracts into the placement slot 12 when there is no external force driving it.

[0042] It should be noted that the eight individual product bodies 21 are, in order, a bipolar electrocoagulation needle, a microscopic straight scissor, a non-invasive microscopic grasping forceps, an ultra-fine curette, a disposable biopsy forceps, a balloon micro-dilation head, a radiofrequency ablation microneedle, and a dissector, which correspond to eight specific functions: hemostasis, cutting, clamping, scraping, biopsy, dilation, ablation, and dissection.

[0043] In this embodiment, the linear driving force is converted into rotational torque through the gear 23-rack 24 transmission, which is stable, without jamming or backlash. Combined with the return spring 27, the single item is automatically retracted, improving the safety and reliability of the operation during surgery.

[0044] Understandably, the module of gear 23, the length of rack 24, and the stroke of transmission slide 25 shown in the attached diagram are only for illustration. The transmission ratio can be adjusted according to the extension angle and extension length requirements of individual products, and is not a unique limitation here.

[0045] In some embodiments, the drive unit 3 includes a support rod 31, a drive push rod 32, and a reset drive spring 33. The support rod 31 is L-shaped, and its lower end is fixedly connected to the upper surface of the suction rod 11, providing support and guidance for the drive push rod 32. The drive push rod 32 is slidably connected to the lateral end of the support rod 31, and its lower end can extend into a pre-set groove inside the drive rod 26 and press against the drive rod 26.

[0046] The reset drive spring 33 is sleeved on the outside of the drive push rod 32, and its two ends are fixedly connected to the lower side of the support rod 31 and the upper side of the suction rod 11, respectively. It is used to keep the drive push rod 32 in the upper position when there is no pressure, so as to avoid accidental triggering of the single item extension during the operation.

[0047] During operation, pressing down on the drive push rod 32 causes the lower end of the drive push rod 32 to press against the drive rod 26 and move downward, compressing the reset spring 27. This, in turn, drives the rack 24 to move via the transmission slide rod 25. The rack 24 drives the gear 23 and the rotating shaft 22 to rotate, causing the single product body 21 to deflect around the rotating shaft 22 and fold out from the inside of the placement slot 12 to the working position. After releasing the drive push rod 32, the reset drive spring 33 drives the drive push rod 32 to move upward and reset. The reset spring 27 pulls the drive rod 26, the transmission slide rod 25, and the rack 24 back to their original positions. The gear 23 rotates in the opposite direction, and the single product body 21 automatically rotates back and is stored in the placement slot 12, restoring the rod body to its flat position.

[0048] It should be noted that the lower end of the drive push rod 32 and the groove of the drive rod 26 are fitted with an arc-shaped surface, which allows for smooth sliding without jamming or off-center load. This embodiment takes manual pressing drive as an example. In other embodiments, electric push rods, slider guide rails and other structures can be added to realize electric control drive, without being limited to manual mode.

[0049] In some embodiments, the dispensing unit 4 includes a handle 41, a rotating disk 42, a rotating ring 43, a dispensing groove 45, a second guide groove 44, and a first guide groove 13. The handle 41 is located at the upper end of the device and is made of medical ABS non-slip material. The rotating disk 42 is fixedly connected to its lower side, and the rotating ring 43 is fixedly connected to the lower end of the rotating disk 42. The rotating ring 43 is rotatably connected to the center of the inner side of the suction rod 11. The rotating ring 43 has a dispensing groove 45 and a second guide groove 44 on its upper side.

[0050] A first guide groove 13 is provided on the upper side of the suction rod 11. The lower end of the drive push rod 32 passes through the first guide groove 13 and the second guide slide 44 in sequence and then extends into the groove of the drive rod 26. By rotating the handle 41, the rotating disk 42 and the rotating ring 43 can be rotated synchronously, so that the adjustment groove 45 is aligned with any one of the eight sets of placement grooves 12 in sequence. Only when the adjustment groove 45 is aligned with a certain placement groove 12 can the drive push rod 32 pass through the second guide slide 44 and press down the corresponding drive rod 26 to realize the single-item single-selection retrieval.

[0051] In this embodiment, the call-out unit 4 implements the single-hand operation logic of "rotating to select function and pressing to select item", which effectively avoids structural interference, visual obstruction and tissue damage caused by multiple items extending at the same time, and the switching is clear and the positioning is accurate.

[0052] It should be noted that the rotation angle of the rotating ring 43 corresponds one-to-one with the eight sets of placement slots 12, and a gear position locking point can be set. There is obvious tactile feedback when the rotation is in place. In other embodiments, positioning beads, slots and other structures can be added to further improve the switching positioning accuracy, which is not limited here.

[0053] Initial state: All eight individual product bodies 21 are stored in their corresponding placement slots 12, flush with the outer wall of the suction rod; the reset spring 27 and the reset drive spring 33 are both in the extended state, and the drive push rod 32 remains in the upper position; the adjustment slot 45 of the rotating ring 43 is not aligned with any placement slot 12, and no individual product can be triggered to extend.

[0054] Product selection: The operator holds the handle 41 with one hand and rotates the handle 41 to drive the rotating ring 43 to rotate, so that the placement slot 12 corresponding to the target functional product is aligned with the adjustment slot 45 on the rotating ring 43. At this time, the second guide groove 44 coincides with the first guide groove 13, and the drive push rod 32 can move downward.

[0055] Single item extension: Press down on the drive push rod 32, the drive push rod 32 pushes the drive rod 26 down and compresses the return spring 27. Through the linkage of the transmission slide rod 25, rack 24, gear 23 and rotating shaft 22, the single item body 21 is driven to deflect around the axis and fold out from the inside of the placement slot 12 to the preset working position. The extension length and deflection angle are limited by the limiting structure.

[0056] Single item reset: Release the drive push rod 32, the reset drive spring 33 pushes the drive push rod 32 to move upward to reset, the reset spring 27 pulls the drive rod 26, the transmission slide rod 25 and the rack 24 back to their original positions, the gear 23 rotates in the opposite direction, the single item body 21 automatically rotates back and is stored in the placement slot 12, and the rod body returns to a smooth and flat state.

[0057] In this embodiment, the entire process of function switching, single-item retrieval, suction operation, and specialized surgical actions can be completed with just one hand, eliminating the need for frequent instrument changes, significantly shortening the operation time, and reducing the risk of intracranial tissue damage.

[0058] In some embodiments, the device also includes a limiting structure, an insulating plating, a sealing structure, an anti-slip texture, and a standard interface. The limiting structure limits the extension angle and length of the main body 21 to prevent excessive extension from damaging nerves and blood vessels. The insulating plating is used for electrocoagulation and radiofrequency devices, with the rod and internal wiring fully insulated, leaving only the working end exposed to prevent intraoperative leakage. The sealing structure completely isolates the transmission cavity, central suction channel, and inflation catheter from each other, preventing blood and cerebrospinal fluid infiltration and ensuring reliable transmission and aseptic requirements. The handle 41 and operating area are provided with an anti-slip knurled texture to improve stability during wet-hand operation. The tail integrates a standard Luer suction interface, electrocoagulation interface, radiofrequency interface, and inflation interface, with a unified layout that is compatible with mainstream neuroendoscopic surgical equipment.

[0059] All parts that come into contact with the human body are made of medical-grade materials, meet biocompatibility standards, and can be reused by autoclaving (except for disposable biopsy forceps), complying with operating room aseptic safety standards.

[0060] It should be noted that the above-mentioned auxiliary structures can be flexibly configured according to different product types. For example, the balloon dilator head can be equipped with a miniature inflation tube and inflation interface, while electrocoagulation / radio frequency products can be equipped with insulated circuits and electrical interfaces. These will not be elaborated on here.

[0061] Example 2

[0062] This instrument is designed to meet the clinical needs of neurosurgical microsurgery. The eight individual components are divided into two differentiated forms according to the mainstream structure in the industry. Both types of instruments integrate suction function, and their appearance and tubing layout are clearly distinguishable, making them suitable for different surgical scenarios.

[0063] The first type is the built-in suction microsurgical instrument. Its structure is based on the commonly used clinical suction device with built-in bipolar electrocoagulation. The microsurgical head and suction channel are coaxially integrated. The instrument itself is a hollow tubular structure, with the internal cavity directly connected to the central negative pressure suction channel of the suction rod. The entire rod is slender with no external tubing, resulting in a simple appearance suitable for delicate microsurgical operations in narrow endoscopic channels and deep surgical locations. When stored, this type of instrument fits perfectly into its placement slot; when extended, it allows for simultaneous microsurgical operations and negative pressure suction. The tubing is concealed and does not occupy additional space.

[0064] The second type is the external suction-equipped microsurgical instrument. It uses standard neurosurgical microsurgical instruments as the main body, with an independent micro-suction tube added to the outside of the instrument shaft. The suction tube is arranged parallel to the instrument body, making the two components—the instrument body and the external suction tube—clearly visible and visually distinct from the internal structure. This structure retains the tactile feel of traditional microsurgical instruments. The external suction tube can independently target and remove bleeding and tissue debris from the surgical area, providing a larger suction flow rate. It is suitable for microsurgical procedures with ample surgical field space and requiring extensive debridement.

[0065] Both types of structures share the same transmission, drive, and switching mechanism, and can be freely switched between by calling up the unit, further improving the versatility and clinical adaptability of the device.

[0066] Working Principle: This modular neuroendoscopic surgical instrument uses the suction device as its basic carrier, and integrates and switches functions through multiple independent structures distributed around the rod. In its initial state, all functional components are housed in the placement slot 12 on the outside of the rod, keeping the rod flat and smooth, allowing for easy entry and exit from the neuroendoscopic operating channel. When a specific function is needed during surgery, the surgeon rotates the handle 41 with one hand, causing the internal rotating ring 43 to rotate synchronously, aligning the adjustment slot 45 on the rotating ring 43 with the placement slot 12 containing the target component, forming a unique triggerable working position. At this time, pressing the upper drive push rod 32 pushes down on the corresponding drive rod 26. The drive rod 26 drives the rack 24 to move via the transmission slide 25. The rack 24 meshes with the gear 23, converting linear motion into rotational motion of the rotating shaft 22, which in turn causes the component body 21 to deflect around the axis, stably folding and extending from the placement slot 12 to the working position. After the operation is completed, the drive push rod 32 is released. Under the combined action of the return spring 27 and the return drive spring 33, the drive push rod 32 moves upward to reset, and each transmission structure returns to its original position in sequence. The single-item body 21 automatically rotates back into the placement slot 12 for storage. Throughout the process, the central suction channel remains independent and unobstructed, allowing for simultaneous suction and field clearing operations. This achieves the integration of suction function and specialized surgical procedures, and the entire process can be controlled with one hand without the need to change instruments.
