Description

Technical Field

[0001] This application relates to the field of surgical equipment technology, and more particularly to a tendon clamp. Background Technology

[0002] During knee cruciate ligament reconstruction surgery, the patient's own tendons, such as the semitendinosus or gracilis tendons, are typically used to restore the normal function of the cruciate ligaments. After the autologous tendon is harvested, it needs to be braided to adapt to the movement requirements of the knee joint. During the braiding process using sutures, hemostatic forceps and other clamping instruments are used to hold the ends of the tendon taut.

[0003] However, during the tendon suturing process, the needle loop needs to be rotated back and forth. The loop can easily slip into the clamping arms of the clamping instrument, thus affecting the surgical process. Summary of the Invention

[0004] The purpose of this application is to at least solve the problem of wire loops easily slipping into the clamping arms of a clamping device. This purpose is achieved by the following means:

[0005] This application discloses a tendon clamp, comprising: a first clamp arm and a second clamp arm. The first clamp arm includes a first clamping portion, a first hinge portion, and a first clamp handle. The first clamping portion is used to clamp a tendon, and both the first clamping portion and the first clamp handle are connected to the first hinge portion, which is located between the first clamp handle and the first clamping portion. The second clamp arm includes a second clamping portion, a second hinge portion, and a second clamp handle. The second clamping portion corresponds to the first clamping portion and is used to clamp a tendon. Both the second clamping portion and the second clamp handle are connected to the second hinge portion, which is located between the second clamp handle and the second clamping portion, and is hinged to the first hinge portion. At least one of the first clamp handle and the second clamp handle is provided with a transition member, which is used to be looped through by a wire loop, and a portion of the transition member is located between the first clamp handle and the second clamp handle.

[0006] The tendon clamp of this application is provided with a transition piece for a suture loop to pass through. The transition piece accommodates the suture loop, thereby reducing the probability of the suture loop slipping between the first and second clamp handles. The transition piece is provided on at least one of the first and second clamp handles, with a portion of the transition piece located between the first and second clamp handles. The transition piece provides a blocking effect on the suture loop, further reducing the probability of the suture loop slipping between the first and second clamp handles.

[0007] In some embodiments, the transition member includes a main body, a first end, and a second end. The main body is located between the first end and the second end and is connected to the first end and the second end. The main body is located on the side of the first end and the second end that is away from the first hinge and the second hinge.

[0008] In some embodiments, the first clamp arm further includes a first collar and a protrusion. In the length direction of the first clamp arm, the first clamp handle and the transition member are located on both sides of the protrusion and connected to the protrusion. The first collar is located on the side of the protrusion near the second clamp handle and connected to the protrusion. The first collar is configured to be able to be inserted by a finger. The protrusion has a protrusion formed on the side of the protrusion opposite to the second clamp handle.

[0009] In some embodiments, the first end is connected to the protrusion, and in the width direction of the first clamp arm, the second end is located on the side of the first end near the second clamp handle, and in the length direction of the first clamp arm, the second end is located on the side of the first end away from the first clamp arm.

[0010] In some embodiments, the second clamp arm further includes a second collar, which is located on the side of the second clamp handle opposite to the second hinge portion and is connected to the second clamp handle. The second collar is configured to allow fingers to be inserted into it, and the second collar is correspondingly provided to the first collar.

[0011] In some embodiments, the second end is spaced apart from the second collar.

[0012] In some embodiments, the transition element is arc-shaped.

[0013] In some embodiments, the first clamp arm further includes a first locking portion disposed on the first clamp handle, and the second clamp arm further includes a second locking portion disposed on the second clamp handle. Both the first locking portion and the second locking portion are provided with locking teeth. The first locking portion has a connected state and a separated state relative to the second locking portion. When the first locking portion is in the connected state, the locking teeth of the first locking portion and the locking teeth of the second locking portion engage and restrict the first clamp handle and the second clamp handle from moving away from each other. When the first locking portion is in the separated state, the locking teeth of the first locking portion and the locking teeth of the second locking portion separate.

[0014] In some embodiments, the dimension of the first clamping portion in the height direction of the first clamping arm is greater than the dimension of the first clamping portion in the length direction of the first clamping arm; the dimension of the second clamping portion in the height direction of the second clamping arm is greater than the dimension of the second clamping portion in the length direction of the second clamping arm.

[0015] In some embodiments, both the first clamping portion and the second clamping portion are provided with a plurality of biting teeth. Attached Figure Description

[0026] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] During knee cruciate ligament reconstruction surgery, the patient's own tendons, such as the semitendinosus or gracilis tendons, are typically used to restore the normal function of the cruciate ligaments. After the autologous tendon is harvested, it needs to be braided to adapt to the movement requirements of the knee joint. During the braiding process using sutures, hemostatic forceps and other clamping instruments are used to hold the ends of the tendon taut.

[0032] However, during the tendon suturing process, the needle loop needs to be rotated back and forth. The loop can easily slip into the clamping arms of the clamping instrument, thus affecting the surgical process.

[0033] To at least address the problem of the wire loop easily slipping between the clamping arms of the clamping device, embodiments of this application propose a tendon clamp 100 that can accommodate the wire loop via a transition piece 3, thereby reducing the probability of the wire loop slipping between the first clamp handle 13 and the second clamp handle 23.

[0034] The tendon clamp 100 of this application embodiment is described below with reference to the accompanying drawings.

[0035] Combination Figure 1 and Figure 2As shown, the tendon clamp 100 of this application embodiment includes: a first clamp arm 1 and a second clamp arm 2. The first clamp arm 1 includes a first clamping part 11, a first hinge part 12, and a first clamp handle 13. The first clamping part 11 is used to clamp tendons. Both the first clamping part 11 and the first clamp handle 13 are connected to the first hinge part 12, and the first hinge part 12 is located between the first clamp handle 13 and the first clamping part 11. The second clamp arm 2 includes a second clamping part 21, a second hinge part 22, and a second clamp handle 23. The second clamping part 21 corresponds to the first clamping part 11 and is used to clamp tendons. Both the second clamping part 21 and the second clamp handle 23 are connected to the second hinge part 22, and the second hinge part 22 is located between the second clamp handle 23 and the second clamping part 21. The second hinge part 22 is hinged to the first hinge part 12. At least one of the first clamp handle 13 and the second clamp handle 23 is provided with a transition member 3. The transition member 3 is used to be looped through by a wire loop, and part of the transition member 3 is located between the first clamp handle 13 and the second clamp handle 23.

[0036] During knee cruciate ligament reconstruction surgery, the harvested autologous tendon is cleaned of any remaining muscle tissue using a scraper. The tendon is then folded in half to form an open end and a closed end. The closed end is secured with a clamp, and the open end is held in place by the tendon clamp 100 according to this embodiment. When holding the open end with the tendon clamp 100, the first clamp handle 13 and the second clamp handle 23 are held by the index and middle fingers, and pressure is applied to either the first clamp handle 13 or the second clamp handle 23 by the thumb, thereby securing the tendon. The tendon is then sutured using a suture loop, which passes through the tendon and then over the transition piece 3 each time until the suture is complete.

[0037] The transition piece 3 is used to be fitted over the wire loop. The transition piece 3 can accommodate the wire loop, thereby reducing the probability that the wire loop will slip between the first clamp 13 and the second clamp 23.

[0038] At least one of the first clamp handle 13 and the second clamp handle 23 is provided with a transition member 3, and a portion of the transition member 3 is located between the first clamp handle 13 and the second clamp handle 23. The transition member 3 has a blocking effect on the wire loop, thereby further reducing the probability of the wire loop slipping into the space between the first clamp handle 13 and the second clamp handle 23.

[0039] Combination Figure 1 and Figure 2 As shown, in some embodiments, the transition member 3 includes a main body 31, a first end 32 and a second end 33. The main body 31 is located between the first end 32 and the second end 33 and is connected to the first end 32 and the second end 33. The main body 31 is located on the side of the first end 32 and the second end 33 that is away from the first hinge portion 12 and the second hinge portion 22.

[0040] By positioning the main body 31 on the side opposite to the first end 32 and the second end 33 from the first hinge portion 12 and the second hinge portion 22, the overall length of the transition member 3 can be increased, and part or all of the main body 31 can be moved away from the first clamp 13 and the second clamp 23.

[0041] By increasing the length of the transition piece 3, a longer guide path can be provided for the wire loop. When the wire loop passes through the transition piece 3, it has more contact area and a longer stroke to be accommodated, making it less likely for the wire loop to deviate into the gap between the first clamp handle 13 and the second clamp handle 23, further reducing the probability of the wire loop getting stuck in the gap between the first clamp arm 1 and the second clamp arm 2.

[0042] The longer transition piece 3 provides greater operating space. When slipping the suture loop over the transition piece 3, it is easier to align the transition piece 3, thereby saving surgical time and improving the convenience and smoothness of the operation.

[0043] By moving part or all of the main body 31 away from the first clamp handle 13 and the second clamp handle 23, the probability of interference between the main body 31 and the first clamp handle 13, and between the main body 31 and the second clamp handle 23, can be reduced, thereby improving the convenience and smoothness of the operation.

[0044] Combination Figure 1 and Figure 2 As shown, in some embodiments, the transition element 3 is arc-shaped.

[0045] The arc-shaped structure can increase the overall length of the transition piece 3 and can also move part or all of the main body 31 away from the first clamp 13 and the second clamp 23.

[0046] The curved transition piece 3 can adapt to the shape of the hand. By making the transition piece 3 curved, it can accommodate a variety of hand movements, thereby improving the comfort and precision of surgical operations.

[0047] Combination Figure 1 and Figure 2 As shown, in some embodiments, the first clamp arm 1 further includes a first collar 14 and a protrusion 16. In the length direction a of the first clamp arm, the first clamp handle 13 and the transition member 3 are located on both sides of the protrusion 16 and connected to the protrusion 16. The first collar 14 is located on the side of the protrusion 16 near the second clamp handle 23 and is connected to the protrusion 16. The first collar 14 is configured to be able to be inserted by a finger. The protrusion 16 has a protrusion on the side away from the second clamp handle 23.

[0048] When the tendon clamp 100 of this application clamps the open end, the index finger is inserted into the first collar 14 to control the movement of the first clamp handle 13, the middle finger controls the movement of the second clamp handle 23, and the thumb applies pressure to the protrusion 16, thereby clamping the tendon.

[0049] When operating the tendon clamp 100 of this embodiment, inserting a finger into the first ring 14 allows for more stable control of the movement of the first clamp arm 1, achieving precise opening and closing control. Furthermore, the position of the first ring 14 close to the protrusion 16 makes the point of force application for the finger more reasonable, conforming to ergonomic principles and helping to improve the accuracy and efficiency of surgical procedures.

[0050] The first clamp handle 13, the transition piece 3, and the first collar 14 are all connected to the protrusion 16. The protrusion 16 can firmly connect the first clamp handle 13, the transition piece 3, and the first collar 14 together, thereby enhancing the overall structural strength of the first clamp arm 1.

[0051] In addition, the protrusion 16 can provide richer tactile feedback, which helps the user to better control the opening and closing degree and force direction of the tendon clamp 100 of this embodiment, thereby improving the comfort and accuracy of operation.

[0052] Combination Figure 1 and Figure 2 In some embodiments, the second clamp arm 2 further includes a second collar 24, which is located on the side of the second clamp handle 23 away from the second hinge portion 22 and is connected to the second clamp handle 23. The second collar 24 is configured to be able to be inserted by a finger, and the second collar 24 is correspondingly provided with the first collar 14.

[0053] When the tendon clamp 100 of this application clamps the open end, the index finger is inserted into the first collar 14 to control the movement of the first clamp handle 13, the middle finger is inserted into the second collar 24 to control the movement of the second clamp handle 23, and pressure is applied to the protrusion 16 by the thumb, thereby clamping the tendon.

[0054] When operating the tendon clamp 100 of this embodiment, inserting a finger into the second collar 24 allows for more stable control of the movement of the second clamp arm 2, achieving precise opening and closing control.

[0055] Combination Figure 1 and Figure 2 As shown, in some embodiments, the first end 32 is connected to the protrusion 16. In the width direction b of the first clamp arm, the second end 33 is located on the side of the first end 32 close to the second clamp handle 23. In the length direction a of the first clamp arm, the second end 33 is located on the side of the first end 32 away from the first clamp arm 1.

[0056] By positioning the second end 33 on the side of the first end 32 near the second handle 23 in the width direction b of the first clamp arm, a portion of the transition piece 3 is positioned between the first handle 13 and the second handle 23, thereby creating a blocking effect on the wire loop and further reducing the probability of the wire loop slipping between the first handle 13 and the second handle 23.

[0057] By positioning the second end 33 on the side of the first end 32 away from the first clamp arm 1 along the length direction a of the first clamp arm, the distance between the second end 33 and the second clamp arm 2 along the length direction a of the first clamp arm can be increased, thus avoiding interference between the second end 33 and the second clamp arm 2.

[0058] Combination Figure 1 and Figure 2 As shown, in some embodiments, the second end 33 is spaced apart from the second collar 24.

[0059] The spacing between the second end 33 and the second loop 24 provides sufficient space for removing the suture loop. When it is necessary to remove the suture loop, the loop is moved to remove it from the gap between the second end 33 and the second loop 24, thereby reducing the difficulty of removing the suture loop, saving surgical time, and improving the convenience and smoothness of the operation.

[0060] Combination Figure 1 and Figure 2 As shown, in some embodiments, the first clamp arm 1 further includes a first locking portion 15 disposed on the first clamp handle 13, and the second clamp arm 2 further includes a second locking portion 25 disposed on the second clamp handle 23. Both the first locking portion 15 and the second locking portion 25 are provided with locking teeth 18. The first locking portion 15 has a connected state and a separated state relative to the second locking portion 25. When the first locking portion 15 is in the connected state, the locking teeth 18 of the first locking portion 15 and the locking teeth 18 of the second locking portion 25 are engaged, and the first clamp handle 13 and the second clamp handle 23 are restricted to move away from each other. When the first locking portion 15 is in the separated state, the locking teeth 18 of the first locking portion 15 and the locking teeth 18 of the second locking portion 25 are separated.

[0061] When it is necessary to put the first locking part 15 in the connected state, pressure is applied to the protrusion 16 by the thumb, which can drive the first locking part 15 and the second locking part 25 to move closer together and make the locking teeth 18 of the first locking part 15 and the locking teeth 18 of the second locking part 25 engage, thereby putting the first locking part 15 in the connected state.

[0062] When it is necessary to separate the first locking part 15, pressure is applied to the protrusion 16 by the thumb, which drives the first locking part 15 and the second locking part 25 to move toward each other. The locking teeth 18 of the first locking part 15 and the second locking part 25 are misaligned, thereby allowing the first locking part 15 and the second locking part 25 to separate from each other. The movement of the first clamp handle 13 and the second clamp handle 23 is controlled, so that the first locking part 15 and the second locking part 25 move away from each other, thereby allowing the first locking part 15 to be in a separated state.

[0063] When the locking teeth 18 of the first locking part 15 and the locking teeth 18 of the second locking part 25 are misaligned, a force can be applied to the first locking part 15 or the second locking part 25 in the height direction c of the first clamp arm, so that the locking teeth 18 of the first locking part 15 and the locking teeth 18 of the second locking part 25 can be separated more smoothly.

[0064] The locking function of the first locking part 15 and the second locking part 25 can fix the first clamp handle 13 and the second clamp handle 23 in a suitable position after clamping tendons and other tissues. The doctor does not need to hold the first clamp handle 13 and the second clamp handle 23 with force to maintain the clamping state. This allows the doctor to focus more energy and attention on other key steps of the operation, thereby improving the convenience and accuracy of the operation.

[0065] Combination Figure 1 and Figure 2 As shown, in some embodiments, the dimension of the first clamping part 11 in the height direction c of the first clamping arm is greater than the dimension of the first clamping part 11 in the length direction a of the first clamping arm; the dimension of the second clamping part 21 in the height direction of the second clamping arm 2 is greater than the dimension of the second clamping part 21 in the length direction of the second clamping arm.

[0066] The dimension of the first clamping portion 11 in the height direction c of the first clamp arm is larger than the dimension of the first clamping portion 11 in the length direction a of the first clamp arm. In other words, the first clamping portion 11 is wider, and by increasing the width of the first clamping portion 11, it can more firmly clamp the tendon, thereby ensuring the smooth progress of the surgery. Furthermore, the larger contact area between the first clamping portion 11 and the tendon allows for the distribution of clamping force when clamping the tendon, preventing damage to the tendon tissue due to excessive local pressure.

[0067] The second clamping portion 21 is larger in the height direction than the length direction of the second clamping arm 2. In other words, the second clamping portion 21 is wider, allowing it to more firmly clamp the tendon and ensuring a smooth surgical procedure. Furthermore, the larger contact area between the second clamping portion 21 and the tendon helps to distribute the clamping force, preventing damage to the tendon tissue due to excessive local pressure.

[0068] Combination Figure 1 and Figure 2 As shown, in some embodiments, both the first clamping part 11 and the second clamping part 21 are provided with a plurality of biting teeth 17.

[0069] Multiple occlusal teeth 17 can fully contact and embed with the tendons and other tissues being clamped, increasing friction and occlusal force, thereby making the tendon clamped more firmly, preventing tendon slippage, and ensuring the smooth progress of the operation.

[0070] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
