Description

Technical Field

[0001] This invention relates to the field of bone tissue separation and cutting technology, specifically to a bone tissue separation and cutting device for surgical procedures. Background Technology

[0002] In the field of surgery, especially in bone grafting surgeries such as orthopedics, spinal surgery, and neurosurgery, it is often necessary to separate and cut bone tissue. In surgeries such as spinal fusion, nonunion repair, bone defect reconstruction, and comminuted fractures, it is often necessary to obtain autologous bone tissue from the patient's iliac bone or other parts for bone grafting. Bone tissue with soft tissue needs to be separated from the bone first, peeling off the muscles, periosteum, connective tissue, etc. on the bone surface, and then cutting the stripped clean bone tissue into bone particles of appropriate size for bone grafting. Therefore, a bone tissue separation and cutting device for surgical procedures is required.

[0003] Existing treatment devices typically involve medical personnel manually scraping away the soft tissue on the surface of bone fragments using instruments such as scalpels and curettes, and then cutting the bone tissue into pieces one by one using bone chisels and bone biting forceps to complete the bone treatment.

[0004] The inventors of this application discovered in their research that the core pain points of the existing clinical practice are as follows: there is a lack of dedicated devices for electrically operated bone separation and bone cutting in current clinical surgeries. All related operations rely on manual operation by medical staff. This not only easily leads to uneven size and shape of the prepared bone particles, which is not conducive to postoperative bone fusion and increases the risk of poor bone graft healing, but also easily causes bone particle splashing, resulting in implant contamination. At the same time, manual operation is time-consuming and inefficient, which not only increases the risks of surgery and anesthesia for patients, but also easily leads to occupational exposure such as cuts for medical staff. The overall operation mode is time-consuming and labor-intensive, and it is difficult to meet the actual application needs of clinical health economics. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a bone tissue separation and cutting device for surgical procedures, resolving the clinical pain point that existing bone tissue separation and cutting methods rely entirely on manual operation by medical staff.

[0006] This device has bone tissue cutting as its core function and bone-meat separation as a supporting function. The two functions are switched in a modular manner to achieve fully automated operation.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a bone tissue separation and cutting device for surgical procedures, comprising a base, a bone-flesh separator, and a bone tissue cutter. The base has an upward-opening placement groove inside, and a slot is formed in the placement groove. The bottom outer walls of the bone-flesh separator and the bone tissue cutter are uniformly fixedly connected with locking blocks, and the outer walls of the locking blocks are disposed in the slots. A drive motor is installed inside the base, and an output rod is fixedly connected to the output end of the drive motor. A spline groove is formed on the top of the output rod, and an output shaft one or an output shaft two is selectively connected to one of the spline grooves of the output rod. The bone and meat separator is equipped with a bone and meat separation module, which includes a guide feed hopper fixedly connected to the inner wall of the bone and meat separator. The bone tissue cutter is equipped with a bone cutting module inside, and the bone cutting module includes an output shaft 2 that is rotatably connected to the bottom of the bone tissue cutter.

[0008] By adopting the above technical solution, using the base as a universal power and control carrier, and the bone separator and bone tissue cutter as optional functional modules, both are mechanically fixed and power-connected to the base through a unified quick-installation structure. During module installation, multiple sets of locking blocks at the bottom of the corresponding functional module's basin are aligned with the slot entrances in the upward-opening placement grooves at the top of the base, allowing the locking blocks to engage. This completes the installation of the basin and base. Simultaneously, the bottom end of output shaft one at the bottom of the bone separator or output shaft two at the bottom of the bone tissue cutter is inserted into the spline groove at the top of the output rod fixed to the drive motor output end within the base, forming a circumferential transmission fit. This allows the rotational power output by the drive motor to be transmitted seamlessly to the internal execution structure of the corresponding functional module, achieving mechanical fixing and power connection in one step, and realizing a unified base... The device features two independent functional modules: a bone-skin separation module and a bone cutting module. Both modules utilize electric automated operation to replace traditional manual medical procedures. Through these modules, standardized, uniform cutting and separation of bone tissue are achieved, resulting in bone particles of uniform size and shape. This effectively improves postoperative bone fusion outcomes and reduces the clinical risks of nonunion and slow fusion. Simultaneously, the integrated electric operation significantly shortens the surgical time for bone-skin separation and bone cutting, improving surgical efficiency and effectively reducing patient exposure time and anesthesia duration, thus lowering surgical and anesthesia-related risks. The fully mechanized operation eliminates the need for medical personnel to manually cut or shred bone tissue, fundamentally avoiding occupational exposure risks such as knife injuries to medical staff, reducing manual operation costs, and aligning with the principles of clinical health economics.

[0013] Preferably, the outer walls of the multiple brushes are all located on the top of the meat separator and are distributed in a pentagonal pattern. The multiple brushes cooperate with each other to form an inverted funnel shape that is wider at the top and narrower at the bottom. The top of the meat separator is hinged with a cover plate.

[0014] Preferably, the top of the bone tissue cutter is provided with positioning grooves evenly distributed, one end of the positioning groove of the bone tissue cutter is provided with a limit groove, positioning blocks are provided in the positioning groove of the bone tissue cutter, and the tops of the multiple positioning blocks are fixedly connected with a top cover.

[0015] Preferably, a feed pipe is fixedly connected to the top of the upper cover, and a push rod is provided inside the feed pipe.

[0016] Preferably, a handle is fixedly connected to the outer wall of the base, and a handle is fixedly connected to the outer walls of the bone and flesh separator and the bone tissue cutter, respectively.

[0017] Preferably, a circuit board is installed inside the base. A start button and a speed control button are respectively installed on one side of the base. The start button and the speed control button are electrically connected to the signal input terminal of the circuit board. The drive motor is electrically connected to the control output terminal of the circuit board. A wiring port is provided on the other side of the base for connecting a DC power line. A lithium battery mounting position is reserved inside the base for configuring a spare lithium battery as a backup power supply.

[0018] This invention provides a bone tissue separation and cutting device for surgical procedures. It has the following beneficial effects: 1. This invention utilizes slots within the base's placement groove to quickly engage and position the bone-skin separator and bone tissue cutter using uniformly fixed locking blocks at their bottoms. Simultaneously, the bottom ends of output shaft one or two are inserted into the spline groove at the top of the output rod of the drive motor, forming a circumferential transmission connection. This allows for the selective installation of two independent functional modules—a bone-skin separation module and a bone cutting module—on the same base, with mechanical fixation and power connection completed in one step. This significantly improves surgical turnaround efficiency, enabling a single power system to drive two different functional modules. Both modules employ electric automated operation to replace traditional manual medical procedures, shortening the surgical time for bone-skin separation and bone cutting, improving surgical efficiency, effectively reducing patient surgical exposure time and anesthesia duration, and lowering surgical and anesthesia-related risks. The fully mechanized operation eliminates the need for medical personnel to manually cut or shred bone tissue, fundamentally avoiding occupational exposure risks such as knife cuts for medical personnel, reducing manual operation costs, and aligning with the principles of clinical health economics.

[0019] 2. In this invention, the top protrusion of the output shaft two is embedded in the positioning hole of the inner wall of the blade to form a circumferential limit. With the fastening screw passing through the mounting hole, the blade is axially locked, so that the blade remains stable under high-speed rotation. The blade rotates synchronously with the output shaft two. The shearing blade forms a shearing action on the bone tissue attached to the blade surface, cutting large pieces of bone tissue into fine particles. After cutting, bone particles that meet the particle size requirements of the blade fall through the discharge port. At the same time, the guide plate collects the bone particles to the discharge port and falls into the receiving frame for centralized collection. This results in more regular bone particle morphology and particle size deviation controlled within a very small range. After implantation, it can form a bone conduction scaffold with uniform pore distribution in the bone graft area, increase the contact and adhesion area with the host bone, and be more conducive to the postoperative bone fusion process, effectively reducing the clinical risks of bone graft nonunion and slow fusion speed.

[0020] 3. In this invention, the output shaft drives the receiving box and the gear ring to revolve. The inner tooth ends of the gear ring simultaneously drive multiple sets of bevel gears to rotate around their own rotation axis, thereby driving the brush body to rotate synchronously. At the same time, all bevel gears and brush bodies revolve around the central axis of the device together with the gear ring, so that multiple sets of brush bodies have a composite motion of high-speed self-rotation and revolution around the center. Moreover, the multiple sets of brush bodies are evenly distributed in a pentagonal shape and form an inverted funnel shape that is wider at the top and narrower at the bottom, realizing all-round wrapping and composite friction peeling of the bone tissue surface, and completely removing the meat residue, fascia and soft tissue attached to the bone tissue.

[0023] The technical solution of the present invention will now be clearly and completely described 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.

[0024] Please see the appendix Figure 1 -Appendix Figure 9 This invention provides a bone tissue separation and cutting device for surgical procedures, including a base 1, a bone-flesh separator 2, and a bone tissue cutter 201. The base 1 has an upward-opening placement groove 7 inside, and a slot 701 is provided in the placement groove 7 of the base 1. The bottom outer walls of the bone-flesh separator 2 and the bone tissue cutter 201 are uniformly fixedly connected with a locking block 702. The outer wall of the locking block 702 is set in the slot 701. A drive motor 8 is installed inside the base 1. The output end of the drive motor 8 is fixedly connected to an output rod 801. The top of the output rod 801 has a spline groove. An output shaft 203 or an output shaft 3 is selectively connected to the spline groove of the output rod 801. The bone and meat separator 2 is equipped with a bone and meat separation module, which includes a guide feed hopper 202 fixedly connected to the inner wall of the bone and meat separator 2. The bone tissue cutter 201 has a bone cutting module inside, which includes an output shaft 23 rotatably connected to the bottom of the bone tissue cutter 201.

[0025] Specifically, with base 1 as the general power and control carrier, bone and flesh separator 2 and bone tissue cutter 201 are optional functional modules. Both are mechanically fixed and power-connected to base 1 through a unified quick-installation structure. During module installation, multiple sets of locking blocks 702 at the bottom of the corresponding functional module's basin are aligned with the slots 701 in the upward-facing placement grooves 7 at the top of base 1, allowing the locking blocks 702 to engage with the slots 701, thus completing the installation of the basin and base 1. Simultaneously, the bottom end of the output shaft 1 203 at the bottom of bone and flesh separator 2 or the bottom end of the output shaft 2 3 at the bottom of bone tissue cutter 201 is inserted into the spline groove at the top of the output rod 801 fixed to the output end of the drive motor 8 inside base 1, forming a circumferential transmission fit. This allows the rotational power output by the drive motor 8 to be transmitted seamlessly to the internal execution structure of the corresponding functional module, achieving mechanical fixing and power connection in one step. This enables the same base 1 to match two independent functional modules: a bone and flesh separation module and a bone cutting module. Both functional modules utilize electric automated operation to replace traditional manual medical procedures. The system is designed to eliminate the need for multiple medical staff to perform tedious manual bone cutting, repeated rinsing, and manual sorting. A single medical staff member can independently complete the entire process from bone tissue cleaning and bone-skin separation to bone particle preparation. Through two functional modules, it achieves standardized mechanical cutting and separation of bone tissue at a uniform speed, thereby producing bone particles of uniform size and shape. This effectively improves postoperative bone fusion and reduces the clinical risks of nonunion and slow fusion. At the same time, the electric integrated operation significantly shortens the operation time of bone-skin separation and bone cutting, improves surgical efficiency, effectively reduces the patient's surgical exposure time and anesthesia duration, and reduces surgical and anesthesia-related risks. The fully mechanized operation eliminates the need for medical staff to manually cut and shred bone tissue, fundamentally avoiding occupational exposure risks such as knife cuts for medical staff. Furthermore, the core power components are reusable for a long time, and only the consumables that come into contact with bone tissue are replaced as needed. Long-term use can reduce the cost of related instruments for a single surgery, adapting to the clinical procurement and usage needs of hospitals of different levels and conforming to the principles of clinical health economics. The bone-meat separation module achieves comprehensive wrapping and compound friction peeling of the bone tissue surface, completely removing the meat scraps, fascia and soft tissue attached to the bone tissue.

[0026] Please see the appendix Figure 6 -Appendix Figure 8 The top of the output shaft 2 3 is uniformly fixedly connected with protrusions 301. The top of the output shaft 2 3 is provided with blades 302. The blades 302 are disc-shaped and are located inside the bone tissue cutter 201. The inner wall of the blades 302 is uniformly provided with positioning holes 303 that are adapted to the protrusions 301. The outer wall of the protrusions 301 is respectively located in the positioning holes 303. The inside of the blades 302 is uniformly provided with discharge ports 304. The top of the blades 302 is located outside the discharge ports 304 and is uniformly fixedly connected with shearing blades 305. Both the blade 302 and the output shaft 3 have mounting holes 309 inside, and fastening screws 310 are threaded inside the mounting holes 309 of the blade 302 and the output shaft 3. The top of the bone tissue cutter 201 is evenly provided with positioning grooves 5. One end of the positioning groove 5 of the bone tissue cutter 201 is provided with a limiting groove 501. Positioning blocks 502 are provided in the positioning groove 5 of the bone tissue cutter 201. The tops of the multiple positioning blocks 502 are fixedly connected with a top cover 503. The top of the cover 503 is fixedly connected to the feed pipe 6, and the feed pipe 6 is equipped with a push rod 601.

[0027] Specifically, after removing the bone and meat separator 2, the bone tissue cutter 201 is installed into the base 1 in the aforementioned quick-installation method, and the bone cutting process can be switched. Before bone cutting, the protrusions 301 evenly distributed on the top of the output shaft 2 3 are embedded in the positioning holes 303 corresponding to the inner wall of the blade 302. The disc-shaped blade 302 is driven to rotate synchronously at high speed through circumferential limiting. The blade 302 and the center of the output shaft 2 3 are respectively provided with mounting holes 309. The fastening screw 310 is threaded into the mounting hole 309 to achieve axial locking and fixation of the blade 302, preventing the blade 302 from axially moving out during high-speed rotation. During bone cutting, when power is transmitted to output shaft 3 via output rod 801, the blade 302 rotates synchronously. The shearing blades 305, which are evenly arranged on the top surface of the blade 302 outside the discharge port 304, form a cutting structure that shears the bone tissue attached to the surface of the blade 302, cutting the bone tissue into fine particles. This improves the cutting efficiency of large-sized bone tissue, resulting in more regular bone particle morphology and particle size deviation within a very small range. After implantation, it can form a bone conduction scaffold with uniformly distributed pores in the bone graft area, increasing the contact area with the host bone and facilitating the progress of postoperative bone fusion. This effectively reduces the clinical risks of nonunion and slow fusion. After cutting, bone particles that meet the particle size requirements fall downward through the evenly arranged discharge port 304 on the blade 302. During operation, bone tissue is fed into the feed pipe 6 at the top of the upper cover 503. The operator pushes the push rod 601 inside the feed pipe 6 to feed the bone tissue from top to bottom, stably pushing the bone tissue to the cutting surface of the blade 302, ensuring continuous contact between the bone tissue and the cutting edge, and preventing the bone block from bouncing and slipping. The upper cover 503 achieves quick rotation and disassembly through the positioning block 502 at the bottom and the positioning groove 5 and limiting groove 501 at the top of the bone tissue cutter 201, which is convenient for replacement and easy to replace blades 302 with different aperture specifications. The bone tissue cutter 201 adopts a reusable structure and can be used multiple times after sterilization. When it is necessary to change to a different particle size blade 302, the discharge port 304 of the blade 302 has three standard specifications of 3mm, 6mm and 9mm available. Different aperture sizes of the blade 302 correspond to the cutting of bone particles of different sizes. That is, the size of the disc blade 302 is used according to the size of the particles to be cut in the operation. The blade 302 can be changed according to the actual use needs. The original blade 302 can be removed by rotating and removing the top cover 503 and unscrewing the fastening screw 310. After replacing with the corresponding size blade 302, it can be locked and fixed. The operation is convenient.

[0028] Please see the appendix Figure 6 Appendix Figure 8 The inner wall of the bone tissue cutter 201 is inclined and fixedly connected to a guide plate 4. A rod hole is opened at the center of the guide plate 4. The outer wall of the output shaft 2 3 is set in the rod hole. A feed port 401 is opened inside the guide plate 4. A through groove 402 is opened on the bottom outer wall of the bone tissue cutter 201. A receiving frame 403 is set in the through groove 402 of the bone tissue cutter 201. The outer wall of the receiving frame 403 is set inside the bone tissue cutter 201. The receiving frame 403 is set below the feed port 401. A handle 404 is fixedly connected to the outer wall of the receiving frame 403.

[0029] Specifically, the bone particles fall onto the upper surface of the guide plate 4, which is inclined and fixed to the inner wall of the bone tissue cutter 201. The rod hole in the center of the guide plate 4 allows the output shaft 2 3 to pass through without interference. The bone particles are collected along the inclined surface of the guide plate 4 to the discharge port 401 and finally fall into the receiving frame 403 below the discharge port 401 for centralized collection. The receiving frame 403 is installed by pulling out through the through groove 402 at the bottom of the bone tissue cutter 201. The operator can hold the handle 404 to pull out the receiving frame 403 and take out the cut bone particles.

[0030] Please see the appendix Figure 1 - Appendix Figure 5 The bottom of the bone and meat separator 2 is rotatably connected to an output shaft 203, the top of the output shaft 203 is fixedly connected to a receiving box 204, the outer wall of the receiving box 204 is set inside the bone and meat separator 2, the top outer wall of the receiving box 204 is fixedly connected to a gear ring 205, the bottom inner wall of the gear ring 205 is fixedly connected to an annular slider 206, the outer wall of the guide feed hopper 202 is fixedly connected to a support ring 207 with a groove, the outer wall of the annular slider 206 is slidably connected in the groove of the support ring 207, the tooth ends of the gear ring 205 are evenly meshed with a bevel gear 208, the inner wall of the bevel gear 208 is fixedly connected to a rotating shaft 209, and the outer wall of the rotating shaft 209 is fixedly connected to a brush body 210. The outer walls of multiple brush bodies 210 are all located on the top of the meat separator 2 and are distributed in a pentagonal pattern. The multiple brush bodies 210 cooperate with each other to form an inverted funnel shape that is wider at the top and narrower at the bottom. A cover plate 211 is hinged to the top of the meat separator 2.

[0031] Specifically, during the meat-bone separation operation, meat and bone tissue are fed in from the top, guided and gathered by the guide feed hopper 202, and precisely fall into the working area surrounded by the brush body 210. Power is transmitted to the output shaft 203 via the output rod 801. The output shaft 203 drives the receiving box 204 to rotate synchronously, and the gear ring 205 revolves together with the receiving box 204. Through the sliding engagement of the annular slider 206 and the groove, stable radial support and axial limiting are provided for the gear ring 205, preventing swaying when the gear ring 205 rotates at high speed. The inner tooth ends of the gear ring 205 maintain meshing with multiple sets of bevel gears 208. When the gear ring 205 revolves, it drives each set of bevel gears 208 to rotate around its own rotation axis 209, thereby driving... The brush body 210 fixed to the outer wall of the rotating shaft 209 rotates synchronously. At the same time, all bevel gears 208 and the rotating shaft 209 revolve around the central axis of the device together with the gear ring 205. Finally, multiple brush bodies 210 simultaneously have a composite motion of high-speed self-rotation and revolution around the center. In this embodiment, there are 5 brush bodies 210, which are evenly distributed according to the five vertices of the pentagram. They are also arranged to form an inverted funnel shape that is wider at the top and narrower at the bottom. This can wrap the surface of bone tissue in all directions. The brush body 210 is similar to a steel wool ball or steel brush. Its rigid friction surface completely peels off the meat, fascia and soft tissue attached to the bone tissue through composite friction motion. The processed bone will fall into the bottom of the container 204 for temporary storage. During operation, the hinged cover plate 211 at the top of the bone and flesh separator 2 and the top cover 503 at the top of the bone tissue cutter 201 can be closed to prevent bone particles from splashing during processing and to avoid contamination of bone particle implants. After completing the bone and flesh separation operation, rotate the bone and flesh separator 2 to disengage the locking block 702 from the locking slot 701, and lift it upwards to remove the bone and flesh separator 2. The bone and flesh separator 2 is a disposable consumable. Its internal components, such as the guide feed hopper 202, the receiving box 204, the gear ring 205, the bevel gear 208, and the brush body 210, are all integrated into one unit. After use, the whole unit is directly discarded without disassembly, cleaning, or sterilization, thus completely avoiding the risk of cross-infection caused by bone tissue and body fluid residues and meeting the requirements of aseptic operation in surgery.

[0032] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 6 The outer wall of the base 1 is fixedly connected to a handle 9, and the outer walls of the bone and flesh separator 2 and the bone tissue cutter 201 are respectively fixedly connected to handle 902 and handle 901.

[0033] Specifically, handle 1 (9), handle 3 (902), and handle 2 (901) facilitate the handling, transfer, and disassembly of modules by operators in different working modes, thereby improving the ease of use of the equipment.

[0034] Please see the appendix Figure 1 Appendix Figure 9 The base 1 has a circuit board 1002 installed inside. A start button 10 and a speed control button 1001 are installed on one side of the base 1. The start button 10 and the speed control button 1001 are electrically connected to the signal input terminal of the circuit board 1002. The drive motor 8 is electrically connected to the control output terminal of the circuit board 1002. A wiring port 1003 is provided on the other side of the base 1. The wiring port 1003 is used for connecting DC power lines. A lithium battery mounting position 1004 can be reserved inside the base 1. The lithium battery mounting position 1004 is used to configure a spare lithium battery as a backup power supply.

[0035] Specifically, when the start button 10 is rotated to the start position, the operation signal is transmitted to the circuit board 1002, the circuit board 1002 outputs a conduction signal to the drive motor 8, and the drive motor 8 starts running. When the start button 10 is rotated to the stop position again, the circuit board 1002 outputs a disconnect signal, and the drive motor 8 stops running, thus realizing the control of the start and stop of the equipment. When the speed control button 1001 is rotated, the gear switching signal is transmitted to the circuit board 1002. The circuit board 1002 switches the output speed of the drive motor 8 by adjusting the voltage / current parameters output to the drive motor 8, so as to realize the high, medium and low speed adjustment. The corresponding speed is matched according to the hardness of bone tissue and different processing procedures, thereby improving processing efficiency and operation stability. The wiring port 1003 on the other side of the base 1 is used to connect an external DC power supply to provide working power to the circuit board 1002 and the drive motor 8. The lithium battery mounting position 1004 is used to configure a backup lithium battery as a backup power source, providing operating power to the device in scenarios where there is no external DC power supply, thereby improving the portability and scenario adaptability of the device.

[0036] Work process: When in use, first install the meat separator 2 onto the base 1, align the locking block 702 at the bottom of the meat separator 2 with the slot 701 entrance in the top placement groove 7 of the base 1, and insert it downwards so that the locking block 702 is locked into the slot 701 to complete the mechanical fixation. At the same time, the bottom end of the output shaft 203 at the bottom of the meat separator 2 is inserted into the spline groove at the top of the output rod 801 of the drive motor 8 in the base 1 to form a circumferential transmission engagement. Meat and bone tissue is fed from the top of the meat-bone separator 2. After being guided and gathered by the feed hopper 202, it falls into the working area surrounded by the brush body 210.
