[0024] In order to make the purpose, technical solutions and advantages of the present application more apparent, example embodiments according to the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application described in this application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of this application.
[0025] The applicant has found that existing electric bone rongeurs usually use a gear transmission mechanism. During long-term use, the gears are prone to wear. The wear of the gears will directly affect the control force of the bone rongeurs, making it difficult to accurately control the cutting force, which may affect the quality and safety of the operation.
[0026] In view of this, in order to solve the above problems, the applicant has proposed a bone structure electric gun-type biting device, see Figure 1 , Figure 1 A cross-sectional schematic diagram of an electric gun-type biting device for bone structure provided in an embodiment of the present application includes: a handle 1, a motor 3, a base 2, a fixed clamp body 4, a push-pull clamp body 5 and a sliding assembly 6.
[0027] Among them, a hollow chamber for accommodating the base 2 is provided in the handle 1, the motor 3 can be fixedly mounted on the base 2, the fixed pliers body 4 is fixedly mounted on the end of the base 2 away from the motor 3, the push-pull pliers body 5 is slidably connected to the fixed pliers body 4, one end of the sliding assembly 6 is connected to the motor 3, and the other end of the sliding assembly 6 is connected to the push-pull pliers body 5, which is used to promote the sliding action of the push-pull pliers body 5 to implement shearing of the bones.
[0028] The present application can set up a motor 3 to drive the sliding assembly 6 to move, push the push-pull pliers body 5 to slide on the fixed pliers body 4, form a shearing effect between the push-pull pliers body 5 and the fixed pliers body 4, and realize cutting of bones. The rotational motion of the motor 3 is converted into the linear sliding motion of the push-pull pliers body 5, which not only avoids the wear problem of gear transmission, but also makes the linear motion easier to control accurately, which helps to improve surgical accuracy.
[0029] The push-pull forceps body 5 and the fixed forceps body 4 can be made of medical stainless steel or titanium alloy. These two materials not only have excellent strength and corrosion resistance, but more importantly, they are easy to carry out strict disinfection to ensure a sterile environment during the operation and effectively avoid cross infection. At the same time, their anti-deformation ability is also extremely good, and they can maintain structural stability and precision even when used for a long time or facing complex surgical operations.
[0030] The handle 1 can be made of high-quality engineering plastic. This material is not only strong and light, which reduces the burden on the hands of medical staff during long operations, but also provides a good grip and operational flexibility, making the use of surgical forceps more handy and further improving the accuracy and efficiency of the operation.
[0031] In addition, the sliding assembly 6 may include an outer sleeve 61, a connecting rod 62 and a bayonet 63. One end of the outer sleeve 61 is connected to the motor 3, and the rotational motion of the motor 3 can be converted into linear motion. The other end of the outer sleeve 61 is connected to one end of the connecting rod 62. The other end of the connecting rod 62 cooperates with the groove of the bayonet 63 to transmit the linear motion of the outer sleeve 61. The other end of the bayonet 63 without a groove can be connected to the push-pull pliers body 5, and the motion of the connecting rod 62 can be transmitted to the push-pull pliers body 5. Through the cooperation of the outer sleeve 61, the connecting rod 62 and the bayonet 63, the power of the motor 3 is transmitted to the push-pull pliers body 5, so that the push-pull pliers body 5 can slide on the fixed pliers body 4, thereby completing the shearing action on the bone.
[0032] The outer sleeve 61 is a rigid tubular component, specifically formed from stainless steel tubing, used to convert the rotational output of the motor 3 into a linear motion power source. The connecting rod 62 is a cylindrical metal rod, specifically machined from a titanium alloy, used to transmit power during linear motion and maintain a rigid connection. The bayonet 63 is a metal connector with a groove structure, specifically manufactured using a stamping process. The groove size matches the shape of the connecting rod end, forming a constraint fit to limit the motion trajectory of the push-pull caliper 5.
[0033] Specifically, the rotational power of the motor 3 is converted into linear reciprocating motion through the outer sleeve 61. One end of the connecting rod 62 is nested within the outer sleeve 61, while the other end is embedded in the groove of the bayonet 63, forming a sliding contact. When the motor 3 drives the outer sleeve 61 to move axially, the connecting rod 62 pushes the push-pull caliper body 5 to slide on the fixed caliper body 4 through the contact surface between the groove and the bayonet 63. The restraining effect of the groove ensures that the push-pull caliper body always maintains a linear motion path parallel to the fixed caliper body 4.
[0034] refer to Figure 2 In this embodiment, the connecting rod 62 and the outer sleeve 61 are detachably connected through a threaded connection. One end of the connecting rod 62 can be provided with an external thread, and the corresponding end of the outer sleeve 61 can be provided with an internal thread, and the connection or disassembly can be achieved by rotation.
[0035] However, there are other ways to achieve a detachable connection, for example, it can be achieved through a snap connection or a plug connection.
[0036] Snap connection: A protrusion or a slot can be provided on the connecting rod 62, and a corresponding slot or protrusion can be provided on the outer sleeve 61. The connection can be completed by aligning and applying appropriate pressure. When disassembling, only reverse force needs to be applied.
[0037] Plug-in connection: The connecting rod 62 can be configured to be tightly inserted into the interior of the outer sleeve 61 and maintained in connection by friction or an additional fixing mechanism.
[0038] Specifically, if the connecting rod 62 becomes worn or damaged due to long-term use, it can be separated from the outer sleeve 61 by rotating the threads or releasing the latch. In this case, only the connecting rod 62 needs to be replaced without disassembling the motor 3 or other components. Because the connecting rod 62 in the sliding assembly 6 is connected to the push-pull caliper body 5 via the bayonet 63, the replacement process only involves partial disassembly and assembly, avoiding the tedious operation of disassembling the entire transmission chain required in traditional integrated structures.
[0039] In addition, a control switch 11 is provided on the handle 1, which can be used to start or shut down the motor 3. By setting the control switch 11 on the handle 1, the operator can conveniently control the working state of the bone clamp without the need for an additional control device, thereby improving the convenience of operation.
[0040] The control switch 11 is an operating component mounted on the outer surface of the handle. Specifically, it can be implemented as a micro switch, push button, or touch sensor. It controls the power-on and power-off status of the motor through circuit signal transmission. This component directly controls the start and stop of the motor by triggering the circuit on and off, eliminating the need for manual mechanical transmission.
[0041] The control switch 11 can also be set as a multi-speed switch, which can not only realize a simple switching function, but also control the speed or working mode of the motor 3. For example, three gears of low speed, medium speed and high speed can be set, so that the operator can choose the appropriate working speed according to the different bone hardness, further improving the flexibility and applicability of the bone clamp.
[0042] Specifically, the control switch 11 is electrically connected to the circuit board 14. When the control switch 11 is triggered, the circuit board 14 sends a control signal to the motor 3. After the motor 3 starts, it drives the outer sleeve 61 in the sliding assembly 6 to produce axial displacement, thereby causing the push-pull clamp body 5 to slide relative to the fixed clamp body 4. The operator can complete the instantaneous control of the start and stop of the motor 3 by pressing the control switch 11 with a single hand, without the need to continuously apply gripping force, thus avoiding the vibration of the clamp body caused by unstable manual force. The linear motion of the motor 3 is converted into precise displacement of the push-pull clamp body 5 through the sliding assembly 6, so that the start and stop positions of the shearing action can be precisely controlled.
[0043] In addition, in order to prevent the motor 3 from vibrating when running for a long time and causing the device in the handle 1 to shift, a limiting boss 12 is also provided in the handle 1 to reduce the shaking and displacement of these components during operation.
[0044] The limiting boss 12 is an annular raised structure fixed to the interior of the handle 1 chamber. It can be formed from metal or rigid plastic and aligned with the end of the motion path of the outer sleeve 61 or connecting rod 62 of the sliding assembly 6. The limiting boss 12 blocks the axial displacement of the sliding assembly 6, thereby limiting the maximum travel range of the push-pull caliper 5. These limiting bosses 12 can be cylindrical, square, or other suitable shapes. The number, size, and location of the limiting bosses 12 can be optimized based on the layout of the internal components.
[0045] Specifically, when the motor 3 drives the outer sleeve 61 of the sliding assembly 6 toward the push-pull caliper body 5, the connecting rod 62 extends outward until its end contacts the limit boss 12. At this time, the limit boss 12 forms a rigid barrier, preventing the sliding assembly 6 from moving forward, ensuring that the engagement range between the push-pull caliper body 5 and the fixed caliper body 4 does not exceed a preset threshold.
[0046] In addition, a circuit board 14 can be provided in the handle 1. The circuit board 14 is electrically connected to the motor 3 and the control switch 11 and is used to control the operating speed and direction of the motor 3. In order to achieve precise control of the operating speed and direction of the motor 3, the circuit board 14 serves as an intermediate control unit and can adjust the operating parameters of the motor 3 according to the input signal of the control switch 11.
[0047] The circuit board 14 refers to an electronic control unit for signal processing and command transmission. The circuit board 14 can be implemented in various ways: 1. Analog circuit control: The input voltage of motor 3 is adjusted through a potentiometer and a resistor network to control the speed of motor 3. The direction control can be achieved by switching forward and reverse through a relay or an H-bridge circuit.
[0048] 2. Digital control: Use a microcontroller (such as STM32, Arduino, etc.) with PWM speed regulation and H-bridge drive circuit to achieve more precise speed and direction control.
[0049] 3. Intelligent control: Combined with sensor feedback (such as Hall sensors and encoders), closed-loop control is achieved to further improve control accuracy and stability.
[0050] The motor 3 is a power source for driving the shearing action, and can be implemented by a DC motor with a reduction mechanism, such as a servo motor with a photoelectric encoder. Its function is to convert electrical energy into linear mechanical motion, providing stable power output for the clamp body.
[0051] Specifically, when the control switch 11 is triggered, the circuit board 14 receives the operating signal and generates a control instruction according to a preset program. This instruction changes the motor's speed by adjusting the pulse width or voltage amplitude. For example, when shearing high-density bone, the speed is reduced to increase the shear force, or the speed is increased during the reset phase to shorten the operation cycle. At the same time, the circuit board 14 controls the motor's rotation direction by switching the electrode polarity. For example, after shearing is completed, the sliding assembly 6 is reversed to return the push-pull clamp body 5 to its initial position. The entire process does not require manual application of external force; the complete action cycle of shearing, holding, and reset can be completed solely through the electronic control system.
[0052] In order to facilitate the assembly and disassembly of the handle 1, the handle 1 can include at least two shell covers, which are buckled together. The two shell covers are connected by buckling, which improves the convenience of assembly. They are fixed into one by snaps or connecting bolts. A hollow chamber is formed between the two shell covers, which not only enhances the stability of the handle 1, but also facilitates disassembly and maintenance. The formed installation chamber can be used to install internal components such as the motor 3 and the battery 13, making the overall structure more compact.
[0053] Specifically, the two shell covers are fastened together to form a sealed structure. The split design allows for quick disassembly during maintenance, avoiding the drawback of traditional one-piece structures that require overall replacement. The fixing method of clips or bolts can be flexibly selected according to the usage scenario. For example, clips are preferred in scenarios where frequent disassembly and assembly are required, while bolts are used in scenarios where high-strength connections are required. The hollow chamber enclosed by the shell covers provides rigid support for the internal components, reducing displacement caused by vibration during shearing operations, while optimizing the spatial layout to integrate components such as the battery 13 and circuit board 14.
[0054] To facilitate gripping, the handle 1 may be provided with an anti-slip texture. This texture increases friction on the surface of the handle 1, allowing the user to hold the rongeur more securely, improving operational safety while also increasing user comfort and precision. A stable grip is particularly important when performing precise control operations such as bone shearing. Furthermore, the anti-slip texture reduces hand fatigue, making it suitable for prolonged use.
[0055] The anti-slip texture refers to the concave and convex structure formed on the surface, which can be achieved through diamond grids, wavy stripes, or dotted protrusions. These geometric forms create resistance by increasing the coefficient of friction on the contact surface. Grip stability refers to maintaining the instrument's position while the operator applies axial pressure, achieved by increasing the static friction between the finger and the instrument surface. The depth of the anti-slip texture can be controlled within the range of 0.2-0.5 mm, ensuring both a comfortable touch and sufficient resistance.
[0056] Specifically, a non-slip texture covers the main gripping area of handle 1. When finger pressure is applied, the concave portions of the texture create a negative pressure adsorption effect, while the raised portions create a microscopic bite with the skin. This dual effect prevents relative displacement between the palm and the instrument even under the high loads of bone shearing, maintaining precise alignment between the push-pull clamp 5 and the fixed clamp 4. As the operator continuously applies force, the textured structure disperses pressure on the hand, preventing grip fatigue caused by excessive pressure on localized skin.
[0057] Furthermore, for patients with unusually hard bones, the occlusal surfaces of the fixed and push-pull jaws 4 and 5 can be enhanced by providing sharp cutting edges, which are then specially hardened. This significantly improves the hardness and wear resistance of the cutting edges, effectively resolving the two major challenges of low efficiency and easy wear of the jaws during shearing of hard bones, and ensuring the smooth progress of the surgery. When faced with complex and ever-changing surgical scenarios, doctors can rely on more reliable and efficient surgical tools to improve surgical success rates while reducing surgical pain and postoperative recovery time for patients.
[0058] A sharp cutting edge is a cutting edge formed through heat treatment of a high-hardness alloy material. This can be achieved using tungsten carbide or ceramic coatings, with a surface roughness controlled to below Ra0.4μm. The occlusal surface, where shearing forces are generated when the two jaws meet, is precisely ground to maintain linear alignment between the cutting edge and the bone contact surface.
[0059] Specifically, when the push-pull pliers 5 is driven by the motor 3 to slide toward the fixed pliers 4, the cutting edges of the two interlocking surfaces form a staggered shearing action. Due to the optimized geometry and surface finish of the cutting edges, rapid shearing is achieved by concentrating stress when contacting bone. The sharp cutting edges reduce frictional resistance with the bone during sliding, reducing the driving force required for the shearing action. The high hardness of the cutting edges allows them to maintain their morphological integrity despite repeated contact with bone, preventing blade blunting due to material deformation.
[0060] In order to solve the power supply problem of the electric gun-shaped bone rongeur, a battery 13 is provided at the end of the handle 1 away from the motor 3, and a protective plate 14 can also be provided on the battery 13.
[0061] Among them, the battery 13 refers to an energy storage device that provides electrical energy to the motor, which can be specifically implemented by a lithium-ion battery 13 group or a disposable battery 13. By arranging the battery 13 at a position away from the motor 3, the interference of vibration and heat generated by the operation of the motor 3 on the battery 13 is reduced.
[0062] Among them, the protection board 14 refers to a protective component used to prevent the battery 13 from overcharging, short circuit or physical impact. Specifically, it can be implemented by a circuit board 14 with a temperature sensor and a circuit breaker. By integrating it on the surface or inside the battery 13, the working status of the battery 13 is monitored and controlled in real time.
[0063] Specifically, the battery 13 is installed in the cavity at the end of the handle through a fixed bracket, and its position is isolated from the motor 3 by a cavity structure, which prevents the heat generated when the motor is running from being transferred to the battery area, thereby reducing the risk of performance degradation of the battery 13 due to high temperature.
[0064] The protective plate 131 is connected to the electrodes of the battery 13 via wires. If it detects abnormal current flow or excessive temperature, it automatically cuts off the power supply circuit, preventing malfunctions caused by overheating or short circuits in the battery 13. Furthermore, the remote placement of the battery 13 places the center of gravity of the device close to the grip area, reducing hand fatigue caused by a shift in center of gravity during operation.
[0065] refer to Figure 4 , Figure 4 This is a physical diagram of an electric gun-type biting device for bone structure provided in an embodiment of the present application. Since the control switch 11 is not turned on, the front ends of the push-pull clamp body 5 and the fixed clamp body 4 are closed.
[0066] Working principle: When performing a shearing operation on a bone position, the medical staff holds the handle 1 so that the bar-shaped fixed clamp body 4 is extended into the bone position that needs to be bitten and cut. By starting the control switch 11 and adjusting the appropriate gear, the motor 3 rotates, and the motor 3 drives the sliding assembly 6 to move, thereby driving the pushing clamp body to move linearly on the fixed clamp body 4, and a shearing effect is formed between the push-pull clamp body 5 and the fixed clamp body 4 to achieve bone cutting.
