Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an orthopedic surgical forceps that prevents steel wire from flying when cutting steel wire. Background Technology

[0002] In clinical orthopedic surgery, orthopedic surgical forceps, namely Kirschner forceps, are frequently used to cut the steel wire to be implanted. Often, the cut wire does not completely meet the surgical requirements, and the doctor needs to perform targeted cutting and trimming before the operation. At this time, due to the small volume of the cut part and the structural factors of the Kirschner forceps itself, the cut part may splatter or break off due to its own elasticity. If it falls into the patient's surgical site, it is not easy to clean and may have an unpredictable impact on the surgical process. Utility Model Content

[0003] This invention provides an orthopedic surgical forceps that prevents steel wire from flying when cutting steel wire, aiming to solve the problem of steel wire easily flying when cutting steel wire in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An orthopedic surgical forceps to prevent wire from flying out when cutting wire, comprising a forceps body;

[0006] The clamp body includes a handle and a clamp head, and the handle drives the clamp head to open or close.

[0007] The pliers head is provided with two scissor blades, and a jaw is formed between the two scissor blades. A first protective cover and a second protective cover are respectively provided on the two scissor blades. The first protective cover and the second protective cover cooperate to close the jaw.

[0008] When the two shear blades are open, the first protective cover separates from the second protective cover. When the two shear blades are closed and the wire has not been cut by the two shear blades, the first protective cover and the second protective cover cooperate to close the jaws to prevent the cut wire from flying out of the jaws.

[0009] A further improved solution: the first protective cover is hemispherical in shape, the second protective cover is hemispherical in shape, and the diameter of the first protective cover is smaller than the diameter of the second protective cover.

[0010] Based on the above technical solution: both the first and second protective covers are designed in a hemispherical shape. This hemispherical design not only provides sufficient enclosed space to prevent wire from splashing, but also ensures that the protective covers fit together smoothly when the shear blades close, reducing gaps and improving protective effectiveness. The diameter of the first protective cover is smaller than that of the second protective cover. This dimensional difference allows the second protective cover to partially cover the first protective cover when the shear blades close, forming a tighter seal. Simultaneously, it ensures that the two protective covers can easily detach without interfering with each other when the shear blades open.

[0011] A further improved solution: the first protective cover is welded around one of the shear blades, and the second protective cover is welded around the other shear blade.

[0012] Based on the above technical solution: The protective cover is fixed to the scissor blade via welding, which offers higher stability and fixation compared to other connection methods. This ensures that the protective cover will not detach or shift due to external forces during the use of the surgical forceps, thus maintaining its correct position and effectively preventing wire spatter. The welded connection creates a tighter seal, reducing gaps between the protective cover and the scissor blade. This allows the two protective covers to fit tightly together when the scissor blade is closed, forming a more enclosed shearing space and further improving the prevention of wire spatter.

[0013] A further improved solution: the first protective cover is a first protective plate, the second protective cover is a second protective plate, and the first protective plate and the second protective plate are staggered in the height direction.

[0014] Based on the above technical solution: the first and second protective plates are staggered in height. This structure provides a barrier at the moment the steel wire is cut, reducing the possibility of steel wire splattering. Because the two protective plates are staggered in height, they together cover a wider area. This means that even if the steel wire generates some splattering force when cut, it is more easily blocked by these two protective plates, thereby reducing the potential harm of steel wire splattering to medical staff and patients.

[0015] A further improved solution: The height of the second protective plate is higher than that of the first protective plate, and when the first protective plate and the second protective plate are in contact, the lower side of the second protective plate contacts the upper side of the first protective plate.

[0016] Based on the above technical solution: because the second protective plate is higher than the first protective plate, the two together form a tight protective system. This design can effectively block the flying debris generated when the steel wire is cut, providing a higher level of protection for medical personnel.

[0017] A further improved solution: the first protective plate is welded above one of the shear blades, and the second protective plate is welded above the other of the shear blades.

[0018] Based on the above technical solution: welding is a high-strength connection method that provides stable mechanical properties. By welding the protective plate above the scissor blade, a strong connection between the protective plate and the scissor blade can be ensured, improving the overall structural stability of the tool. The welded protective plate can withstand greater impact forces, which helps protect the scissor blade from damage caused by accidental impacts. At the same time, this design also allows the surgical forceps to maintain good performance during prolonged use.

[0019] A further improvement: Both the first protective cover and the second protective cover are transparent covers that facilitate observation of the jaws.

[0020] Based on the above technical solution, the transparent shield design allows medical staff to clearly observe the working status of the clamp jaws, including the degree of closure of the scissor blades, the cutting position of the wire, and the state of the wire after cutting. This helps medical staff to more accurately judge the progress of the surgery, improving the precision and safety of the operation. Because the clamp jaws can be clearly observed, medical staff can more easily avoid errors, such as incomplete closure of the scissor blades or inaccurate cutting positions. This helps reduce potential risks during surgery and improves the success rate.

[0021] A further improvement: The handle is provided with anti-slip texture, which is arranged in a grid pattern.

[0022] Based on the above technical solution, the grid-like anti-slip texture design significantly increases the friction between the handle and the user's hand, thus providing greater stability when holding the surgical forceps. This stability is particularly important for surgeries requiring prolonged holding or delicate manipulation, as it helps reduce errors caused by hand fatigue or slippage. The anti-slip texture design not only improves grip stability but also enhances the user's control over the surgical forceps. By increasing the contact area and friction between the hand and the handle, the user can more accurately control the movement and force of the surgical forceps, thereby improving the precision and safety of the surgery.

[0023] A further improved solution: The anti-slip texture is set on the handle through a protective sleeve, and the protective sleeve is fitted onto the handle, with the anti-slip texture and the protective sleeve forming an integral structure.

[0024] Based on the above technical solution, the integrated structure of the protective sleeve and anti-slip texture makes the handle more ergonomic, providing a more comfortable grip. This helps reduce hand fatigue and discomfort caused by prolonged gripping, improving the efficiency of surgical procedures for medical personnel. The protective sleeve protects the handle, reducing wear and damage caused by frequent use and cleaning. This helps extend the lifespan of the surgical forceps and reduce maintenance and replacement costs.

[0025] A further improvement: The clamp body is also equipped with a spring that keeps the clamp head in the open state when the handle is not under force.

[0026] Based on the above technical solution, the spring design allows the forceps head to automatically remain open when the handle is not under force. This means that when needed, medical personnel can simply squeeze the handle to close the forceps head for cutting. When not in use, the forceps head automatically springs open, allowing medical personnel to easily remove the forceps from the surgical area and avoid unnecessary damage to surrounding tissues or organs. This design greatly improves the convenience and efficiency of surgical procedures.

[0027] The beneficial effects of this utility model are as follows:

[0028] By incorporating a first and second protective shield, and ensuring they cooperate to close the jaws when the shear blades are closed, this orthopedic surgical forceps significantly reduces wire splattering during the cutting process. This helps protect the safety of medical staff and patients, preventing them from being injured by flying wire.

[0029] With the presence of the first and second protective shields, medical staff can perform wire-cutting operations with greater confidence, without worrying about accidents caused by flying wire. This helps improve the efficiency and success rate of the surgery.

[0030] This invention relates to orthopedic surgical forceps. By incorporating a first and second protective shield, which engage to close the jaws when the blades are closed, it successfully solves the problem of wire splattering in existing technologies. This design not only improves surgical safety and efficiency but also enhances the durability and operability of the forceps. Furthermore, it makes cleaning and maintenance of the forceps more convenient and efficient. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by users of the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0039] refer to Figures 1 to 4 An orthopedic surgical forceps to prevent wire from flying when cutting wire, comprising forceps body 1;

[0040] The clamp body 1 includes a handle 2 and a clamp head 3, wherein the handle 2 drives the clamp head 3 to open or close.

[0041] The pliers head 3 is provided with two scissor blades 4, and a jaw 5 is formed between the two scissor blades 4. A first protective cover 6 and a second protective cover 7 are respectively provided on the two scissor blades 4. The first protective cover and the second protective cover cooperate to close the jaw 5.

[0042] When the two shear blades 4 are open, the first protective cover 6 and the second protective cover 7 are disengaged. When the two shear blades 4 are closed and the steel wire has not been cut by the two shear blades 4, the first protective cover and the second protective cover cooperate to close the jaws 5 to prevent the cut steel wire from flying out of the jaws 5.

[0043] Specifically: the first protective cover 6 is hemispherical in shape, the second protective cover 7 is hemispherical in shape, and the diameter of the first protective cover 6 is smaller than the diameter of the second protective cover 7. The first protective cover 6 is welded around one of the shear blades 4, and the second protective cover 7 is welded around the other shear blade 4.

[0044] The opening direction of the first protective cover 6 is opposite to the opening direction of the second protective cover 7. The first protective cover 6 can also be integrated with one of the shear blades 4, and the second protective cover 7 can also be integrated with the other shear blade 4.

[0045] refer to Figure 3 The first protective cover 6 and the second protective cover 7 can also be replaced by protective plates. The first protective cover 6 is the first protective plate, and the second protective cover 7 is the second protective plate. The first protective plate and the second protective plate are offset in the height direction. The height of the second protective plate is higher than the height of the first protective plate. When the first protective plate and the second protective plate are engaged, the lower side of the second protective plate contacts the upper side of the first protective plate. The first protective plate is welded above one of the shear blades 4, and the second protective plate is welded above the other shear blade 4. Alternatively, the first protective plate can be integrally formed with one of the shear blades 4, and the second protective plate can also be integrally formed with the other shear blade 4.

[0046] Specifically: Both the first protective cover 6 and the second protective cover 7 are transparent covers that facilitate observation of the jaws 5. The first protective cover 6 and the second protective cover 7 can be made of plastic material.

[0047] The handle 2 is provided with anti-slip texture, which is arranged in a grid pattern. The anti-slip texture is attached to the handle 2 via a protective sleeve, which is integrally formed with the handle 2. The clamp body 1 is also provided with a spring 8 that keeps the clamp head 3 in the open state when the handle 2 is not under force. The protective sleeve can be made of plastic. There are two handles 2; one end of the spring 8 is welded to one handle 2, and the other end of the spring 8 is welded to the other handle 2.

[0048] The working principle of this embodiment:

[0049] When medical staff need to open the jaws 5 to grip the wire, they will grasp the handle 2 and cause it to open the jaws 3. During this process, the first protective cover 6 and the second protective cover 7 will disengage from each other as the shear blades 4 open, ensuring that the jaws 5 can open smoothly and grip the wire.

[0050] When medical staff grip handle 2 to close the forceps 3, the two shear blades 4 gradually approach each other and eventually form a narrow jaw 5.

[0051] During this process, the first protective shield 6 and the second protective shield 7 cooperate with each other as the shear blade 4 closes, fitting tightly together to form a closed shearing space. This closed space ensures that at the moment the wire is cut, the flying force of the wire is effectively blocked inside the jaws 5, thereby preventing the wire from flying out of the jaws 5 and causing injury to medical staff and patients.

[0052] When the jaws 5 close to a certain extent, the two shear blades 4 simultaneously apply shearing force to the wire. As the shearing force increases, the wire is gradually cut at the jaws 5. At the moment the wire is cut, due to the tight fit between the first protective cover 6 and the second protective cover 7, the flying force of the wire is effectively blocked inside the jaws 5, preventing the wire from flying off.

[0053] After cutting the wire, medical staff can release handle 2 to allow the clamps 3 to open again. During this process, the first protective shield 6 and the second protective shield 7 will disengage as the shear blades 4 open, preparing for the next clamping and cutting operation.

[0054] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
