Description

Technical Field

[0001] This disclosure pertains to the field of medical devices, and specifically relates to an oral needle holder. Background Technology

[0002] Needle holders are commonly used medical instruments in surgical procedures and suturing, primarily for holding surgical needles. They are designed with special teeth to firmly grip different types of surgical needles while allowing surgeons precise control over needle movement to complete delicate suturing work. Due to the unique oral environment and limited operating space, the design of oral needle holders must take these factors into account to ensure optimal control and flexibility.

[0003] Existing oral needle holders do not hold suture needles in an accurate position, and the forceps beaks are prone to shifting when they bite, making the suture needle not hold securely. This can cause the suture needle to accidentally detach and injure the patient during suturing, affecting the doctor's operation. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an oral needle holder.

[0005] This disclosure provides an oral needle holder, including a hinged first handle and a second handle, and: The first jaw is located at the other end of the first handle opposite to the hand-held end; The second jaw is located at the other end of the second handle opposite to the hand-held end; The first clamping surface of the first jaw has an arc-shaped protrusion facing the second clamping surface of the second jaw. The arc-shaped protrusion has a needle-holding groove that penetrates the first jaw. The second clamping surface has a matching arc-shaped groove. The first jaw and the second jaw cooperate through the arc-shaped protrusion and the arc-shaped groove so that the second clamping surface cooperates with the needle-holding groove to clamp the surgical needle.

[0006] In one embodiment, the needle-holding groove is an arc-shaped needle-holding groove adapted to the arc-shaped protrusion.

[0007] In one embodiment, the needle-holding groove is located in the middle of the first clamping surface along the direction from the end of the first jaws to the first jaw handle.

[0008] In one embodiment, the needle-holding groove is an arc groove within the orthographic projection section of the first clamp beak extension direction.

[0009] In one embodiment, the central angle of the arc groove is 120°-140°.

[0010] In one embodiment, on a cross section perpendicular to the extension direction of the first clamping handle, the central angle of the arcuate protrusion on the first clamping surface is 15°-25°. On a cross section perpendicular to the extension direction of the second clamp handle, the central angle of the arc-shaped groove on the second clamping surface is 15°-25°.

[0011] In one embodiment, within the orthographic projection section of the extension direction of the second jaw, along the direction from the end of the second jaw to the second jaw handle, the second jaw is a cone with an increasing cross-sectional area, and the second clamping surface is an elongated shape with equal cross-sectional areas and two rounded ends, and the elongated shape and the cone are internally tangent near the ends.

[0012] In one embodiment, within the orthographic projection section of the first jaw beak extension direction, along the direction from the end of the first jaw beak to the first jaw handle, a portion of the length of the first jaw beak and the shape of the first clamping surface are the same, both being elongated strips that match the first clamping surface.

[0013] In one embodiment, the needle-holding groove of the first pincer beak is a magnetic needle-holding groove; or, the needle-holding groove is provided with a magnetic coating.

[0014] In one embodiment, when the first clamping surface and the second clamping surface abut against each other, a clearance groove is provided at the end of the stop surface where the first clamp handle and the second clamp handle are in contact.

[0015] One of the beneficial effects of the oral needle holder disclosed herein is that, by providing an arc-shaped protrusion on the first clamping surface and a corresponding arc-shaped groove on the second clamping surface, and simultaneously providing a through-hole needle-holding groove on the arc-shaped protrusion, the needle-holding groove can determine the clamping position of the surgical needle when the first and second jaws are engaged. The second clamping surface and the needle-holding groove cooperate to stably hold the needle, and the arc-shaped protrusion and the arc-shaped groove cooperate with each other to prevent the position of the first and second jaws from shifting, thereby ensuring that the surgical needle can be firmly clamped by the oral needle holder, improving the safety and efficiency of the operation, and preventing the surgical needle from falling and injuring the patient.

[0019] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0020] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0021] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0022] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0024] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0025] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0026] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0027] Existing oral needle holders do not hold suture needles in an accurate position, and the forceps beaks are prone to shifting when they bite, making the suture needle not hold securely. This can cause the suture needle to accidentally detach and injure the patient during suturing, affecting the doctor's operation.

[0028] Therefore, this disclosure provides an oral needle holder, including a hinged first handle and a second handle, as well as a first beak and a second beak. The first beak is located at the other end of the first handle opposite to the hand-held end; the second beak is located at the other end of the second handle opposite to the hand-held end. The first clamping surface of the first beak has an arc-shaped protrusion on the second clamping surface facing the second beak. The arc-shaped protrusion has a needle-holding groove that penetrates the second beak. The second clamping surface has a matching arc-shaped groove. The first beak and the second beak cooperate through the arc-shaped protrusion and the arc-shaped groove so that the second clamping surface cooperates with the needle-holding groove to clamp the surgical needle.

[0029] Thus, the oral needle holder disclosed herein, by providing an arc-shaped protrusion on the first clamping surface and a corresponding arc-shaped groove on the second clamping surface, and simultaneously providing a through-hole needle-holding groove on the arc-shaped protrusion, allows the needle-holding groove to determine the clamping position of the surgical needle when the first and second jaws are engaged. The second clamping surface and the needle-holding groove work together to stably hold the needle, and the arc-shaped protrusion and the arc-shaped groove cooperate with each other to prevent the position of the first and second jaws from shifting, thereby ensuring that the surgical needle can be firmly clamped by the oral needle holder, improving the safety and efficiency of the operation, and preventing the surgical needle from falling and injuring the patient.

[0030] See Figure 1 and Figure 7In one embodiment, the oral needle holder of this disclosure includes a hinged first handle 1 and a second handle 2, as well as a first jaw 11 and a second jaw 21. The first jaw 11 is disposed at the other end of the first handle 1 opposite to the hand-held end; the second jaw 21 is disposed at the other end of the second handle 2 opposite to the hand-held end; the first clamping surface 111 of the first jaw 11 has an arc-shaped protrusion on the second clamping surface 211 facing the second jaw 21, and the arc-shaped protrusion has a needle-holding groove 1111 that penetrates the first jaw 11. The second clamping surface 211 has a matching arc-shaped groove. When the first jaw 11 and the second jaw 21 are engaged by the arc-shaped protrusion and the arc-shaped groove, the second clamping surface 211 engages with the needle-holding groove 1111 to hold the surgical needle.

[0031] In detail, the first handle 1 of the oral needle holder disclosed herein has a first jaw 11 at the opposite end of its hand, with a first clamping surface 111 on the first jaw. The second handle 2 has a second jaw 21 at the opposite end of its hand, with a second clamping surface 211 corresponding to the first clamping surface 111. The first clamping surface 111 has an arc-shaped protrusion facing the second clamping surface 211, and the second clamping surface 211 has a matching arc-shaped groove. The arc-shaped protrusion and the arc-shaped groove cooperate to ensure that the first jaw 11 and the second jaw 21 are stably engaged and do not shift. At the same time, the arc-shaped protrusion has a through-hole needle-holding groove 1111 to determine the position of the surgical needle.

[0032] When holding the surgical needle, the second clamping surface 211 engages with the needle-holding groove 1111 to hold the surgical needle and determine its position. The arc-shaped protrusion and the arc-shaped groove cooperate to prevent the first jaw 11 and the second jaw 21 from shifting, which would cause the surgical needle to become unstable. Furthermore, the oral needle holder of this disclosure uses arc-shaped protrusions and grooves for positioning. Compared to using a square structure, the arc-shaped structure has a smooth transition, which can avoid sharp edges scratching organs and tissues. The arc-shaped structure can also avoid stress concentration in the square structure, preventing fatigue fracture after long-term use. When closed, the arc-shaped surface contact generates a smooth resistance gradient, making it easy for the operator to perceive the "positioned" state.

[0033] Furthermore, the first handle 1 and the second handle 2 of the oral needle holder disclosed herein are hinged together by a fixed shaft 3. The handheld ends of the first handle 1 and the second handle 2 are respectively equipped with latches 4 and finger rings 5. The physician can control the rotation of the two handles around the fixed shaft 3 by manipulating these two latches 4 and finger rings 5, thereby precisely adjusting the biting state of the first jaw 11 and the second jaw 21. This design allows the physician to perform delicate operations, ensuring precision during the suturing process. In addition, the handheld ends of the first handle 1 and the second handle 2 are also equipped with cooperating latches 4, which provide additional stability during operation, helping the physician reduce hand fatigue during prolonged surgeries and improving the accuracy and efficiency of the operation.

[0034] See Figure 9 The oral needle holder disclosed herein connects the first handle 1 and the second handle 2 via a pin, achieving a flexible yet stable connection suitable for applications requiring precise control of the rotation angle. Simultaneously, it is simple to assemble, facilitating later maintenance or component replacement; its small size saves space; and the cylindrical pin can withstand high shear forces, ensuring the stability of the mechanical structure under dynamic loads. Furthermore, a chamfer is provided at the shaft hole to guide the fixed shaft 3 smoothly into the hole, preventing jamming due to burrs or misalignment, and also preventing burrs from snagging the thread during suturing.

[0035] See Figure 7 In one embodiment, the needle holding groove 1111 is an arc-shaped needle holding groove adapted to the arc-shaped protrusion.

[0036] Thus, the needle-holding groove 1111 is designed to be an arc shape that matches the arc protrusion. The second clamping surface 211 can cooperate with the needle-holding groove 1111 to tighten the surgical needle and prevent the surgical needle from sliding in the needle-holding groove 1111. Furthermore, the surgical needle includes various curved surgical needles. Those skilled in the art can adjust the curvature of the arc protrusion and the arc groove, and then adjust the curvature of the needle-holding groove 1111 to adapt to surgical needles with different curvature radii, ensuring full circumferential contact of the needle body and reducing clamping slippage.

[0037] See Figure 4 In one embodiment, the needle holding groove 1111 is located in the middle of the first clamping surface 111 along the direction from the end of the first jaw 11 to the first clamping handle 1.

[0038] Specifically, along the direction from the end of the first jaw 11 to the first handle 1, the distance between the end of the first clamping surface 111 near the hand-held end and the end of the first jaw 11 is set as a first preset distance, and the distance between the needle-holding groove 1111 and the end of the first jaw 11 is set as a second preset distance. The ratio of the first preset distance to the second preset distance is 1.7:1-2.7:1.

[0039] Furthermore, the needle-holding groove 1111 is located in the middle of the first clamping surface 111, and the needle-holding groove 1111 is perpendicular to the end of the first jaw 11 pointing towards the first handle 1. The needle-holding groove 1111 in the middle allows the clamping force to be symmetrically transmitted along the center line of the jaw, avoiding stress concentration on one side; the vertical design makes it easier for the surgeon to predict and control the position and movement of the surgical needle. If the needle-holding groove 1111 is angled, additional manual adjustment may be required to compensate for the deviation caused by the angle, which increases the difficulty of operation and may lead to errors. A clearly defined groove edge perpendicular to the length direction of the jaw helps the surgeon to accurately align the surgical needle, which is especially important when performing delicate operations.

[0040] See Figure 3 and Figure 4In one embodiment, the needle-holding groove 1111 is an arc groove in the orthographic projection section of the first jaw 11 extending in the direction of extension.

[0041] In this way, the shape of the arc-shaped groove mimics the arc contour of the surgical needle, ensuring that the needle can be securely placed within the groove without slipping. The size of the arc-shaped groove varies depending on the different suturing needs and needle size to accommodate different specifications of surgical needles. The arc-shaped design increases the contact area between the needle holder and the surgical needle, thereby improving the gripping force and making it more stable and reliable during delicate operations. The arc-shaped groove design provides better feel and control, making the actions of clamping, positioning, and releasing the surgical needle smoother and more natural. This design helps reduce operational errors caused by needle holder slippage during surgery, improving the safety and success rate of the operation. At the same time, the arc-shaped groove design takes into account the need for easy cleaning, avoiding the cleaning difficulties that sharp corners or complex structures may present, and helping to maintain the requirements of a sterile environment.

[0042] See Figure 3 In one embodiment, the central angle of the arc groove is 120°-140°.

[0043] The size of the central angle of the arc groove needs to be carefully designed to ensure that the surgical needle can be placed securely within the groove and will not easily slip. If the groove is too wide, the surgical needle may slip within the groove, resulting in unstable clamping; while if the groove is too narrow, it may make it difficult to place or remove the surgical needle.

[0044] The central angle is determined based on the curvature of the most commonly used surgical needle to provide optimal fit and stability. To increase friction and prevent needle slippage, the interior of the groove may undergo specific surface treatments, such as roughening or the addition of anti-slip materials. This can be tailored to specific applications, and this disclosure does not impose any limitations.

[0045] See Figure 7 In one embodiment, on a cross section perpendicular to the extending direction of the first clamping handle 1, the central angle of the arc-shaped protrusion on the first clamping surface 111 is 15°-25°. On a cross section perpendicular to the extension direction of the second clamping handle 2, the central angle of the arc-shaped groove on the second clamping surface 211 is 15°-25°.

[0046] In detail, during surgery, tissue resistance or operational vibrations can easily cause the first jaw 11 and the second jaw 21 to shift. The central angle of the arc-shaped groove in this disclosure is consistent with the central angle of the arc-shaped protrusion, thereby ensuring that the first clamping surface 111 and the second clamping surface 211 can fully cooperate, avoiding shifting when the first jaw 11 and the second jaw 21 engage, and thus ensuring stable clamping of the surgical needle. Furthermore, the central angle of the arc-shaped protrusion on the first clamping surface 111 is 15°-25°, and correspondingly, the central angle of the arc-shaped groove on the second clamping surface 211 is 15°-25°. The arc-shaped protrusion and the arc-shaped groove smoothly transition to the first clamping surface 111 and the second clamping surface 211, respectively, to avoid scratching organ tissue. The size of the central angle can be determined by those skilled in the art according to the specific application scenario, and this disclosure does not impose any limitations on it.

[0047] See Figure 2 , Figure 5 and Figure 6 In one embodiment, in the orthographic projection section of the extension direction of the second jaw 21, along the direction from the end of the second jaw 21 to the second jaw handle 2, the second jaw 21 is a cone with an increasing cross-sectional area, and the second clamping surface 211 is a long strip with equal cross-sectional area and two rounded ends, and the long strip and the cone are inscribed together near the end.

[0048] With this configuration, the second clamping surface 211 is a long strip with equal cross-sectional area and rounded ends. Since the second clamping surface 211 has an arc-shaped groove, the edge of the groove smoothly transitions with the second jaw 21. The second jaw 21 is a cone with increasing cross-sectional area. Thus, the arc-shaped groove and the second jaw 21 work together to further expand the area of ​​the groove, and the end of the second jaw 21 will not be too large to obstruct the doctor's view during operation.

[0049] Therefore, while the second clamping surface 211 engages with the first clamping surface 111, the second jaw 21 further encloses the first clamping surface 111, enhancing the stability of the engagement between the first clamping surface 111 and the second clamping surface 211. Simultaneously, the elongated and tapered incisions near the end maximize the area of ​​the second clamping surface 211, facilitating its engagement with the elongated first clamping surface 111 described below, and reducing the machining difficulty of the first clamping surface 111.

[0050] See Figure 2 , Figure 3 and Figure 4 In one embodiment, in the orthographic projection section of the first jaw 11 extending in the direction of the first jaw 11, along the direction from the end of the first jaw 11 to the first jaw handle 1, a portion of the length of the first jaw 11 and the shape of the first clamping surface 111 are the same, both being elongated strips that match the first clamping surface 111.

[0051] In detail, the length of the first jaw 11 is the same as the shape of the first clamping surface 111, which simplifies the processing of the first jaw 11. Furthermore, the length of the first jaw 11 and the first clamping surface 111 are both elongated strips that match the first clamping surface 111, while the second jaw 21 is a cone with an increasing cross-sectional area. This asymmetrical design allows the second clamping surface 211 of the second jaw 21 to better wrap around the first clamping surface 111. The first jaw 11 has no protruding edge relative to the first clamping surface 111, so it will not obstruct the wrapping of the second clamping surface 211.

[0052] Furthermore, in the oral needle holder of this disclosure, along the central axis direction, the length of the first clamping surface 111 is less than the length of the second clamping surface 211, and the ratio of the length of the first clamping surface 111 to the length of the second clamping surface 211 is 0.97:1-0.98:1, thereby enabling the second clamping surface 211 to completely cover the first clamping surface 111.

[0053] See Figure 3 In one embodiment, the needle-holding groove 1111 of the first jaw 11 is a magnetic needle-holding groove; or, the needle-holding groove 1111 is provided with a magnetic coating.

[0054] In detail, this disclosure allows the needle holder groove 1111 to be a magnetic needle holder groove through a special process. Pulse magnetization, due to its high efficiency and non-destructive nature, has become the preferred magnetization method in many industrial applications. It utilizes an instantaneously generated extremely high-intensity current to produce a strong magnetic field through a coil. This process typically takes only a few microseconds to a few milliseconds, but can generate a magnetic field strength sufficient to saturate most magnetic materials.

[0055] To ensure long-term stability and corrosion resistance, magnetic alloys or composite materials suitable for medical environments can be selected as the materials for the needle holder groove 1111. Through a pulse magnetization process, the needle holder groove 1111 of the needle forceps can acquire appropriate magnetism, thereby improving clamping stability and enhancing the user experience, without affecting its basic functions and service life.

[0056] Alternatively, a thin magnetic layer can be formed on the surface of the needle holder 1111 using a coating or paint technology containing magnetic particles. The magnetic coating provides additional adhesion, helping to secure surgical needles of different sizes and shapes, reducing the risk of accidental slippage during surgery. This allows surgeons to more easily position and manipulate the needles, improving surgical efficiency and precision.

[0057] See Figure 8 In one embodiment, when the first clamping surface 111 and the second clamping surface 211 abut against each other, a clearance groove is provided at the end of the stop surface where the first clamp handle 1 and the second clamp handle 2 are attached.

[0058] In detail, the oral needle holder of this disclosure has a stop surface, which prevents the first handle 1 and the second handle 2 from getting stuck beyond their normal range of motion due to excessive force when rotating around the fixed axis 3, thus preventing the instrument from becoming unusable. Furthermore, since the physician needs to operate the oral needle holder to hold the surgical needle, the stop surface of the first handle 1 and the second handle 2 can easily get the needle caught when rotating around the fixed axis 3.

[0059] Therefore, when the first clamping surface 111 and the second clamping surface 211 abut against each other, a clearance groove is provided at the end of the stop surface where the first clamp handle 1 and the second clamp handle 2 are attached. The clearance groove of this disclosure is formed by setting a chamfer on the stop surface where the first clamp handle 1 and the second clamp handle 2 are attached. The angle of the chamfer can be 30°-60°, and the angle of the clearance groove is 60°-120°, thereby preventing sharp edges from scratching tissue or snagging sutures.

[0060] Furthermore, the beaks of the oral needle holders currently used in clinical practice are too long, which is not suitable for the anatomical characteristics of the oral cavity depth of Chinese people. In addition, the beaks that are too short will also affect the accuracy of the surgeon's suturing. Therefore, the oral needle holder of this disclosure has a beak length of 16-18mm, which is moderate and more suitable for the oral cavity depth of Chinese people.

[0061] For better understanding, please refer to the following... Figures 1 to 9 The working principle of the oral needle holder provided in this disclosure will be explained in detail with an application scenario.

[0062] In use, medical personnel hold the disclosed oral needle holder, insert their fingers into the latches 4 and rings 5 ​​at the hand ends of the first handle 1 and the second handle 2 respectively, open the needle holder, and place the tail of the surgical needle into the needle holder groove 1111 of the first clamping surface 111 with their other hand. They then grip the first handle 1 and the second handle 2 tightly, bringing the hand ends together to engage the latches 4, thereby bringing the first jaws 11 and the second jaws 21 together to clamp the surgical needle in the needle holder groove 1111 of the first clamping surface 111. The magnetic needle holder groove 1... 111 can achieve the effect of stabilizing the surgical needle. The arc-shaped protrusion of the first clamping surface 111 and the arc-shaped groove of the second clamping surface 211 cooperate with each other to prevent the first clamp beak 11 and the second clamp beak 21 from shifting. At this time, the surgical needle can be clamped without the need for finger force. After the surgical needle passes through the oral mucosa, the medical staff uses tweezers to clamp the tip of the surgical needle with one hand and applies force with the other hand to open the buckle 4 of the oral needle holder, and the surgical needle is released. Then, the beak of the oral needle holder clamps the tail of the surgical needle and makes the surgical needle completely pass through the oral mucosa.

[0063] The oral needle holder disclosed herein has a simple structure, with a clear position for the needle clamping beak and magnetic attraction to prevent the needle from falling out. The arc-shaped protrusion of the first clamping surface 111 and the arc-shaped groove of the second clamping surface 211 cooperate with each other to prevent the first clamping beak 11 and the second clamping beak 21 from shifting, thereby stabilizing the clamping of the surgical needle, reducing the difficulty of wound suturing for medical staff, and alleviating the patient's pain.

[0064] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein. The scope of this disclosure is defined by the appended claims.
