[0037] When the first end rotates away from the first gripping rod, the traction rope pulls the second end to rotate away from the second rod. The above-mentioned adjustable angle meningeal scissors are designed to have a first rod and a second rod rotatably connected to the first rod, so that the meningeal scissors have the function of adjusting the angle. By adjusting the angle, a pair of meningeal scissors can meet the needs of various situations, thereby solving the problem of requiring a large number of different types of meningeal scissors in some surgeries.

[0038] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0039] See also Figure 1-Figure 3 , an embodiment of the present application provides an angle-adjustable meningeal scissors, including a hand-held component, a cutting component and a traction rope, wherein the hand-held component includes a first grip and a second grip, and the first grip is rotatably connected to the second grip; the first grip includes a first rod and a second rod, the first rod is rotatably connected to the second grip, the second rod has a first rotation point, one end of the first rod is rotatably connected to the first rotation point, the cutting component includes a first scissors and a second scissors, the first scissors is fixedly connected to an end of the second rod away from the first rod, and the second scissors is rotatably connected to the second rod; one end of the traction rope is connected to the second grip, and the other end is connected to one end of the second scissors, wherein the end of the second grip connected to the traction rope is the first end, and the end of the second scissors connected to the traction rope is the second end, when the first end rotates away from the first grip, the traction rope pulls the second end to rotate in a direction away from the second rod.

[0040] Specifically, the handheld assembly provides a handle structure for manipulating the meningeal scissors, and the rotating connection design enables the operator to adjust the angle of the scissors more flexibly. The cutting assembly is responsible for cutting the meningeal tissue, wherein the fixed connection of the first scissors ensures a stable cutting operation, while the rotating connection of the second scissors increases the adjustability of the scissors angle. The design of the traction rope enables the operator to adjust the angle of the scissors by rotating the second grip, providing an intuitive and convenient way to control the operation of the tool.

[0041] In a specific example, a fastening screw is provided at the first rotation point, and the fastening screw is used to fix the relative position of the first rod and the second rod.

[0042] Specifically, the first rotation point is set to realize the adjustable angle function of the handheld component. The fastening screw is used to fix the relative position of the first rod and the second rod. This design has many important functions and beneficial effects, including

[0043] The presence of the fastening screw ensures that the relative position of the first rod and the second rod is firmly fixed, preventing accidental angle changes during the use of the handheld component. By adjusting the fastening screw, the operator can fix or loosen the relative position of the first rod and the second rod according to specific surgical needs, thereby achieving angle adjustment of the handheld component. The angle of the handheld component can be adjusted according to specific surgical scenarios and requirements, so that the meningeal scissors can adapt to different meningeal surgical needs and improve the flexibility and operability of the operation.

[0044] In a specific example, the fastening screw is provided with a first knob and a second knob at both ends thereof;

[0045] The fastening force of the fastening screw on the first rod and the second rod is controlled by adjusting the distance between the first knob and the second knob.

[0046] Specifically, the two ends of the fastening screw are respectively connected to the first knob and the second knob. By adjusting the distance between the two knobs, the fastening force of the fastening screw on the first rod and the second rod can be controlled. This design has many important functions and beneficial effects. The adjustment of the first knob and the second knob can achieve precise control of the fastening screw, so that the doctor can fine-tune the relative position of the first rod and the second rod according to actual needs. By rotating the knob, the doctor can adjust the fastening force of the fastening screw at any time during the operation, so as to flexibly adapt to different surgical scenarios and needs. The adjustable performance of the fastening screw ensures that during the operation, the handheld component will not be accidentally moved due to the screw being too tight or too loose, thereby improving the safety and stability of the operation.

[0047] In a specific example, the first knob and the second knob are both provided with anti-slip grooves.

[0048] Specifically, the design of the first knob and the second knob takes into account the user's hand feel and operation accuracy during operation, so anti-slip patterns are provided on their surfaces. The presence of anti-slip patterns increases the friction of the knob, making it easier for the user to grasp and less likely to slip during adjustment, thereby improving the stability of use. The texture of the anti-slip patterns fits the fingers, providing a more comfortable hand feel, reducing the user's hand fatigue when turning the knob, and making the surgical operation smoother. The design of the anti-slip patterns not only improves the hand feel, but also allows the user to adjust the knob more accurately, ensuring that the force of the tightening screws on the first rod and the second rod is accurately controlled.

[0049] In a specific example, the first rod is provided with a first wire collection ring, the second rod is provided with a second wire collection ring, and the traction rope passes through the first wire collection ring and the second wire collection ring;

[0050] The first wire take-up ring and the second wire take-up ring are both used to limit the movement of the traction rope.

[0051] Specifically, the setting of the first take-up ring and the second take-up ring limits the movement of the traction rope, thereby ensuring precise control during the operation. This is critical for delicate operations such as shearing the meninges during surgery. By limiting the movement of the traction rope, excessive traction on the meninges can be prevented during use, reducing potential risks caused by misoperation and helping to maintain the safety of the operation. The limitation of the traction rope helps maintain the stability of the meningeal scissors, ensuring that doctors can complete the meningeal cutting operation more accurately and reliably.

[0052] In a specific example, a first slide rail is provided on the first rod, a second slide rail is provided on the second rod, the first wire take-up ring is slidably connected to the first slide rail, and the second wire take-up ring is slidably connected to the second slide rail.

[0053] Specifically, the sliding connection between the first take-up ring and the first slide rail, and the sliding connection between the second take-up ring and the second slide rail help maintain the smooth movement of the traction rope during operation. This is crucial for fine control during surgical operations. The setting of the slide rail not only provides a damping mechanism, but also provides the doctor with additional control over the movement of the traction rope. This helps to more accurately grasp the movement of the meningeal scissors during surgery. The design of the slide rail makes the entire shearing mechanism more adjustable, and the doctor can adjust the position of the slide rail according to specific surgical needs to obtain a better operating experience.

[0054] Furthermore, when the doctor adjusts the angle of the meningeal scissors through the hand-held assembly during use, the rotation of the first grip and the second grip pulls the traction rope, and the first wire collection ring and the second wire collection ring slide on the corresponding slide rails. This design ensures that the movement of the scissors is smooth and controllable when performing meningeal shearing.

[0055] In a specific example, the first grip bar has a first grip ring, and the second grip bar has a second grip ring, and the first grip ring and the second grip ring are used to receive fingers.

[0056] Specifically, the first gripping rod and the second gripping rod are respectively provided with a first gripping ring and a second gripping ring. The setting of the first gripping ring and the second gripping ring takes into account the principle of ergonomics, which helps to provide doctors with a more comfortable and stable grip when using the meningeal scissors. This is crucial for the precision and accuracy of surgical operations. The design of the gripping ring allows the doctor to fix his fingers in a suitable position, so as to better control the movement of the meningeal scissors. This helps to reduce the doctor's hand fatigue during surgical operations and improve the efficiency of the operation. Through the fixation of the gripping ring, the doctor can more accurately control the angle and position of the meningeal scissors and achieve more precise control of the surgical process. This is especially important for some neurosurgery operations that require highly delicate operations.

[0057] In a specific example, a guide groove is provided on the second rod, and a top block is provided on the second scissors;

[0058] The top block can be received in the guide groove, a spring is arranged in the guide groove, when the top block is controlled by external force to rotate toward the second rod, the top block can compress the spring, and when the top block is not subjected to external force, the spring pushes the top block to reset.

[0059] Specifically, the design of the top block enables it to be accommodated in the guide groove, so that it can remain relatively fixed when the scissors rotate. When the top block is controlled by an external force and rotates toward the second rod, it can move in the guide groove. A spring is provided in the guide groove, and its function is to provide a certain damping force when the top block is subjected to an external force and compresses the spring. This helps to better control the movement of the scissors during the surgical operation, prevent sudden movement of the scissors, and increase the stability of the operation. At the same time, the spring plays a role in resetting the second scissors. When the spring can cause the second scissors to rotate to abut against the first scissors, it is beneficial to the continuous cutting of the scissors.

[0060] In one embodiment, the trimming component is a titanium alloy.

[0061] Specifically, titanium alloy is a lightweight and high-strength material, and its use can reduce the weight of the entire meningeal scissors. The lightweight design is very important for the surgeon's durability and precision in surgical operations, helping to reduce the doctor's hand fatigue and improve the operability of the operation. Titanium alloy has excellent strength and corrosion resistance, which allows the scissors to maintain stability and durability for longer in a surgical environment. This durability is crucial for medical operations that require long-term surgery. Titanium alloy has good biocompatibility, reducing the possibility of allergic reactions and other adverse reactions caused by surgical instrument materials. This is crucial to the safety and success of the surgical procedure.

[0062] In a specific example, the traction rope is connected to the second gripping rod bolt, and the traction rope is connected to the second scissors bolt.

[0063] Specifically, the traction rope can be relatively easily separated from the second gripping rod and the second scissors by bolt connection. This is convenient for cleaning, maintenance or replacement of the scissors parts. This detachability improves the maintainability and operability of the meningeal scissors.

[0064] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
