Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a surgical clamp ligation forceps. Background Technology

[0002] Many surgical procedures require ligation of blood vessels or other fluid or tissue conduits (such as veins and arteries) during incision. For example, many surgeries require cutting blood vessels and may necessitate ligation to reduce blood flow to the surgical site. Additionally, in some cases, surgeons may wish to permanently ligate blood vessels. This can be done using ligation clips or surgical sutures. Using surgical sutures requires complex manipulation of the needle and suture material to create the necessary knot to secure the vessel. This complex process is time-consuming and difficult, especially in endoscopic surgery characterized by limited space and visibility. In contrast, ligation clips are relatively easy and quick. Therefore, the use of ligation clips in both endoscopic and open surgical procedures has increased significantly.

[0003] Currently, commercially available ligation forceps work by gripping an external surgical clip with the forceps head and then clamping the clip onto blood vessels or other tissues. This method requires repeated gripping of the external surgical clip and is prone to deviation during gripping. Therefore, designs that allow surgical clips to be inserted into the ligation forceps have also emerged. Although this method can accommodate multiple surgical clips at once and push them out to the forceps head accordingly, the surgical clips are also prone to getting stuck inside the ligation forceps, making them impossible to push out. Furthermore, when pushing out the surgical clips, they are prone to flying out and falling into the patient's body, posing a safety hazard and hindering the operation. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a surgical clamp ligation forceps that can accommodate multiple surgical clamps and precisely and stably extend them to prevent them from falling out, effectively improving the safety of the surgery. Furthermore, the trigger design of the handle allows the user to control the extension process, facilitating the surgical procedure.

[0005] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0006] A surgical clamp ligation forceps includes a fixed handle, a rotatable grip on the fixed handle, a push-pull rod disposed inside the fixed handle and pushed by the grip, a clamping rod pushed by the push-pull rod, and a clamp head disposed on the end of the clamping rod away from the handle. Surgical clamps are sequentially arranged and placed inside the clamping rod. The forceps also include an outer sleeve sleeved outside the clamping rod and a push-clamp spring slidably disposed on the clamping rod. A transverse column is formed on one end of the surgical clamp. Several push-clamp springs are formed on the push-clamp spring, extending obliquely towards the front end of the inner wall of the clamping rod. The front end of the push-clamp spring has a push-limiting opening that is generally semi-circular and presses and limits the transverse column. Several anti-backward springs are formed on the clamping rod, extending obliquely towards the front end of the inner wall of the push-clamp spring. The front end of the anti-backward spring has an anti-backward limiting opening that is generally semi-circular and presses and limits the transverse column.

[0007] As a further improvement of this utility model, at least one first anti-missile piece is formed on the side of the clamping rod near the jaw head and the side near the push clamping piece, which bends and extends inward toward the inside of the clamping rod and the jaw head. At least one second anti-missile piece is formed on the other side of the clamping rod near the jaw head, which bends inward toward the jaw head and extends toward the jaw jaw.

[0008] As a further improvement of this utility model, the first anti-missile plate includes a first anti-missile connecting plate connected to one side of the clamping rod near the jaws and extending horizontally toward the jaws of the clamping rod; a first anti-missile inclined plate connected to the first anti-missile connecting plate facing the jaws of the clamping rod and extending obliquely toward the inside of the clamping rod and the jaws of the clamping rod; and a first anti-missile extension plate connected to the first anti-missile inclined plate facing the jaws of the clamping rod and extending horizontally toward the jaws of the clamping rod. The second anti-missile plate includes a second anti-missile inclined plate connected to the other side of the clamping rod near the jaws and extending obliquely toward the inside of the clamping rod and the jaws of the clamping rod; and a second anti-missile extension plate connected to the second anti-missile inclined plate facing the jaws of the clamping rod and extending horizontally toward the jaws of the clamping rod.

[0009] As a further improvement of this utility model, it also includes an anti-deviation spring plate disposed on one of the outer walls of the clamping rod and hinged to the jaw head. The jaw head includes an upper jaw head rotatably disposed on one of the outer walls of the clamping rod and a lower jaw head rotatably disposed on the outer wall of the clamping rod and disposed opposite to the upper jaw head. The anti-deviation spring plate includes an anti-deviation main body spring plate disposed on the outer wall of the clamping rod, an upper anti-deviation limiting spring plate formed on the anti-deviation main body spring plate and extending towards the jaw head and connected to the upper jaw head, and a lower anti-deviation limiting spring plate formed on the anti-deviation main body spring plate and extending towards the jaw head and connected to the lower jaw head. The upper anti-deviation limiting spring plate and the lower anti-deviation limiting spring plate converge with each other when no external force is applied.

[0010] As a further improvement of this utility model, the upper anti-deviation limiting spring sheet has an upper anti-deviation pressing piece formed at one end near the upper jaw, which bends upward to press and limit the upper jaw; the lower anti-deviation limiting spring sheet has a lower anti-deviation pressing piece formed at one end near the lower jaw, which bends downward to press and limit the lower jaw; one side of the upper jaw has an upper jaw limiting piece extending horizontally toward the handle, and the upper anti-deviation pressing piece presses against the upper jaw limiting piece; one side of the lower jaw has a lower jaw limiting piece extending horizontally toward the handle, and the lower anti-deviation pressing piece presses against the lower jaw limiting piece.

[0011] As a further improvement of this utility model, an excitation block is formed inside the fixed handle in an arc shape and on the rotation trajectory of the handle. Several excitation steps are formed at one end of the excitation block facing the handle. An excitation movable plate is formed on the handle and extends horizontally backward. An excitation movable step extends laterally at the tail end of the excitation movable plate. The excitation movable plate does not contact the excitation block, and the excitation movable step slides on the several excitation steps.

[0012] As a further improvement of this utility model, the end of the excitation block facing the handle is further provided with a confirmation step located at the upper end of the excitation step and a reset step located at the end of the excitation block away from the excitation step.

[0013] As a further improvement of this utility model, an upper support member is provided between one outer wall of the clamping rod and the outer sleeve. The upper support member has at least one rib that extends radially and faces the clamping rod on its inner wall. The rib is semi-circular in shape.

[0014] As a further improvement of this utility model, it also includes a support bar disposed inside the push-pull rod and pushing the push clamp spring, wherein the upper and lower ends of the support bar are each formed with several protrusions that extend sequentially toward the inner wall of the clamping rod.

[0015] As a further improvement of this utility model, the diameter of the outer tube is 9 mm to 10 mm.

[0016] The beneficial effects of this utility model are as follows:

[0017] This surgical clamp ligation forceps is configured to include a fixed handle, a rotatable grip on the fixed handle, a push-pull rod located inside the fixed handle and pushed by the grip, a clamping rod pushed by the push-pull rod, and a clamp head located on the end of the clamping rod away from the handle. The surgical clamps are sequentially arranged and placed inside the clamping rod. It also includes an outer sleeve sleeved outside the clamping rod and a push-clamp spring slidably disposed on the clamping rod. A transverse column is formed on one end of the surgical clamp. Several push-clamp springs are formed on the push-clamp spring, extending obliquely towards the front end of the inner wall of the clamping rod. The front end of the push-clamp spring has a push-limiting opening that is generally semi-circular and presses and limits the transverse column. Several anti-backward springs are formed on the clamping rod, extending obliquely towards the front end of the inner wall of the push-clamp spring. The front end of the anti-backward spring has an anti-backward limiting opening that is generally semi-circular and presses and limits the transverse column.

[0018] The clamping rod is fixed to the fixed handle. One end of the horizontal column on each set of surgical clamps presses against the anti-backward limit port of the corresponding anti-backward spring. Because of the semi-circular structure of the anti-backward limit port, the surgical clamp is effectively prevented from backing away during the pushing process, which is conducive to the accurate ejection of the surgical clamp.

[0019] When it is necessary to clamp the surgical clips onto blood vessels or other tissues, the user presses the handle, which pushes the push-pull rod. The push-pull rod moves the outer sleeve forward and the push clip spring forward on the clamping rod. The push-pull spring's push-out limit port presses against the other end of the transverse column of a set of surgical clips. The other end of the transverse column of the surgical clip is pressed against the push-out limit port, causing the push clip spring to push the surgical clip to the anti-backward limit port of the previous set of anti-backward springs. Because of the semi-circular structure of the push-out limit port, the surgical clip cannot back out when pushed by the push-out spring, thus completing the purpose of moving the surgical clips forward by one set. At the same time, the first set of surgical clips is pushed onto the clamp head. The outer sleeve is moved forward by the push-pull rod, causing the inner wall of the front end of the outer sleeve to press against the open clamp head, closing the clamp head and thus closing the surgical clips inside the clamp head, clamping the surgical clips onto blood vessels or other tissues. The entire process is convenient to use, effectively and precisely pushing multiple surgical clips out of the forceps head one by one and securing them to blood vessels and other tissues accordingly. This avoids the need to repeatedly clamp and remove the surgical clips, saving surgical time, improving surgical efficiency, preventing them from falling off, and effectively improving surgical safety.

[0069] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods of this utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0070] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0071] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0072] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0073] Please refer to Figures 1 to 32This utility model embodiment provides a surgical clamp 06 multi-shot ligation forceps, including a fixed handle 01, a handle 02 rotatably disposed on the fixed handle 01, a push-pull rod 03 disposed inside the fixed handle 01 and pushed by the handle 02, a clamping rod 04 pushed by the push-pull rod 03, and a clamp head 05 disposed on the end of the clamping rod 04 away from the handle 02. The surgical clamps 06 are sequentially arranged and placed inside the clamping rod 04. It also includes an outer sleeve 07 sleeved outside the clamping rod 04 and a push-clamp spring 08 slidably disposed on the clamping rod 04. A transverse column 061 is formed on one end of the 6. Several push-clamp springs 081 are formed on the push-clamp spring 08, which extend obliquely towards the front end of the inner wall of the clamping rod 04. The front end of the push-clamp spring 081 has a push-limiting port 0811 that is semi-arc in shape and presses and limits the transverse column 061. Several anti-backward springs 041 are formed on the clamping rod 04, which extend obliquely towards the front end of the inner wall of the push-clamp spring 08. The front end of the anti-backward spring 041 has an anti-backward limiting port 0411 that is semi-arc in shape and presses and limits the transverse column 061.

[0074] The clamping rod 04 is fixed to the fixed handle 01. One end of the transverse column 061 on each set of surgical clamps 06 presses against the anti-backward limit port 0411 of the corresponding anti-backward spring 041. Because of the semi-arc structure of the anti-backward limit port 0411, the surgical clamp 06 is effectively prevented from backing away during the pushing process, which is conducive to the accurate release of the surgical clamp 06.

[0075] When it is necessary to secure the surgical clip 06 to blood vessels or other tissues, the user presses the handle 02. The handle 02 pushes the push-pull rod 03, which moves the outer sleeve 07 forward and the push clip spring 08 forward on the clip rod 04. The push-pull spring 08's push-out limit port 081 presses against the other end of the transverse column 061 of a set of surgical clips 06. The other end of the transverse column 061 of the surgical clip 06 is pressed by the push-out limit port 0811, thereby pushing the surgical clip 06 to the previous set of anti-reverse springs. On the anti-reverse limiting port 0411 of 041, due to the semi-circular structure of the push-out limiting port 0811, the surgical clip 06 cannot retract when pushed by the push-out spring 081, thus achieving the purpose of moving the surgical clip 06 forward by one set. At the same time, the first set of surgical clips 06 is pushed onto the forceps head 05, and the outer tube 07 is driven forward by the push-pull rod 03, so that the inner wall of the front end of the outer tube 07 presses against the open forceps head 05, closing the forceps head 05 and thus closing the surgical clips 06 inside the forceps head 05, so that the surgical clips 06 are tightly attached to blood vessels and other tissues. The whole process is convenient to use, effectively and accurately pushing multiple surgical clips 06 onto the forceps head 05 in sequence and correspondingly attaching them to blood vessels and other tissues, avoiding the need for repeated clamping and removal of surgical clips 06, saving surgical time, improving surgical efficiency, preventing them from falling off, and effectively improving surgical safety.

[0076] Preferred, such as Figures 7 to 11 As shown, to prevent the push clip spring 08 from moving excessively on the clamping rod 04, several travel limiting grooves 047 are arranged on the side wall of the clamping rod 04, and several travel limiting blocks 082 that move within the travel limiting grooves 047 are formed on the push clip spring 08. The length of the travel limiting groove 047 is the distance that each surgical clip 06 needs to be pushed forward, so that each time the push clip spring 08 is driven to slide, it can push forward a set of surgical clips 06 exactly, preventing the push clip spring 08 from moving excessively.

[0077] To inform the user that the surgical clip 06 inside the clip lever 04 has been used up, such as... Figure 15 As shown, the last surgical clip 06 inside the clip lever 04 is set as a warning clip with a different structure. When the warning clip is pushed out, the user can know that the surgical clip 06 inside the clip lever 04 has been used up and the clip lever 04 needs to be replaced, which is conducive to the user's control over the continuous ligation forceps of this surgical clip 06.

[0078] For the specific usage of this surgical clip 06 consecutive ligation forceps, such as... Figures 1 to 4As shown, in the first step, the user pushes the handle 02, and the surgical clamp 06 is pushed out from the clamp lever 04 onto the clamp head 05. The outer tube 07 moves forward slightly to press and close the clamp head 05, thus slightly tightening the clamp head 05 and preventing the surgical clamp 06 from flying out of the clamp head 05. In the second step, the user continues to push the handle 02, and the outer tube 07 continues to move forward to the end, completely tightening the clamp head 05, thus closing and securing the surgical clamp 06 to blood vessels or other tissues. In the third step, the user continues to push the handle 02, and the outer tube 07 can no longer move forward, and the handle 02 rotates to the end. In the fourth step, the user releases the handle 02, and the handle 02 returns to its original position.

[0079] To prevent the surgical clip 06 from flying off the forceps head 05 during ejection, such as Figures 9 to 14 As shown, at least one first anti-missile plate 042 is formed on the side of the clamping rod 04 near the forceps head 05 and the side near the push clamp spring 08, extending inwards towards the clamping rod 04 and the forceps head 05. At least one second anti-missile plate 043 is formed on the other side of the clamping rod 04 near the forceps head 05, extending inwards towards the jaws of the forceps head 05. When the user presses the handle 02 to push out the surgical clip 06 from the clamping rod 04, the surgical clip 06 is symmetrically clamped and limited at the front end of the clamping rod 04 by the first anti-missile plate 042 and the second anti-missile plate 043, thereby buffering the impact force of the clamping rod 04 on the surgical clip 06. This effectively prevents the surgical clip 06 from flying out of the jaws of the forceps head 05 and falling into the patient's body due to excessive pushing force, ensuring the safety of the surgery. By configuring the first anti-missile plate 042 as a structure that bends inward toward the clamping rod 04 and extends toward the jaws of the clamp head 05, and configuring the second anti-missile plate 043 as a structure that bends inward toward the clamping rod 04 and extends toward the jaws of the clamp head 05, the first anti-missile plate 042 and the second anti-missile plate 043 together form a triangular shape extending inward toward the clamping rod 04. As the surgical clamp 06 is pushed into the jaws of the clamp head 05 within the clamping rod 04, the resistance force from the first anti-missile plate 042 and the second anti-missile plate 043 increases, thereby stabilizing the surgical clamp 06 at the jaws of the clamp head 05. This achieves the purpose of buffering the forward impact force on the surgical clamp 06, effectively preventing the surgical clamp 06 from flying out of the jaws of the clamp head 05 and falling into the patient's body, thus improving the safety of the surgery.

[0080] Regarding the specific structural design of the first anti-missile plate 042, as follows: Figures 9 to 10As shown, the first anti-missile clip 042 includes a first anti-missile connecting piece 0421 connected to one side of the clamping rod 04 near the jaw 05 and extending horizontally toward the jaws of the jaws 05; a first anti-missile inclined piece 0422 connected to the first anti-missile connecting piece 0421 facing the jaws of the jaws 05 and extending obliquely toward the inside of the clamping rod 04 and the jaws of the jaws 05; and a first anti-missile extension piece 0423 connected to the first anti-missile inclined piece 0422 facing the jaws of the jaws 05 and extending horizontally toward the jaws of the jaws 05. The first anti-missile connecting piece 0421 is used to connect the first anti-missile clip 042 to the clamping rod 04. Its horizontal structure ensures connection while facilitating stamping and forming, thus improving production efficiency. By configuring the first anti-flying tilting plate 0422 to extend tilted inward toward the inside of the clamping rod 04 and toward the jaws of the clamp head 05, the resistance force on the surgical clip 06 pushed from the clamping rod 04 on its tilting surface gradually increases until it is relatively stopped and limited on the first anti-flying extension plate 0423. This effectively prevents the surgical clip 06 from flying out of the jaws of the clamp head 05 and falling into the patient's body due to excessive pushing force when it is pushed out, thus ensuring the safety of the operation. By setting the first anti-flying extension plate 0423 to extend horizontally toward the jaws of the forceps head 05, when the surgical clip 06 is pushed onto the first anti-flying extension plate 0423, its side presses against the first anti-flying extension plate 0423 and is buffered by the first anti-flying extension plate 0423. However, it will not be unable to be pushed onto the jaws of the forceps head 05 due to the increasing resistance caused by the tilting action of the first anti-flying tilting plate 0422. This ensures that the surgical clip 06 will not fly away and also ensures the normal operation of the delivery.

[0081] Preferred, such as Figures 9 to 10 As shown, the number of the first anti-missile plates 042 is three sets, which are evenly arranged on one side of the tube wall of the clamp rod 04, so that the blocking force on one side of the surgical clamp 06 is uniform, preventing the surgical clamp 06 from shifting and improving the accuracy of the ligation forceps in clamping the blood vessel.

[0082] Regarding the specific structural design of the second anti-missile plate 043, as follows: Figures 12 to 13As shown, the second anti-launch clip 043 includes a second anti-launch tilting plate 0431 connected to the other side of the clamping rod 04 near the jaw 05 and extending obliquely inward toward the clamping rod 04 and the jaws of the jaw 05, and a second anti-launch extension plate 0432 connected to the end of the second anti-launch tilting plate 0431 facing the jaws of ... By setting the second anti-flying extension plate 0432 to extend horizontally toward the jaws of the forceps head 05, when the surgical clip 06 is pushed onto the second anti-flying extension plate 0432, its side presses against the second anti-flying extension plate 0432 and is buffered by the second anti-flying extension plate 0432. However, unlike the second anti-flying tilting plate 0431, the obstruction force it receives under the tilting action will not increase, which would prevent it from being pushed onto the jaws of the forceps head 05. This ensures that the surgical clip 06 will not fly away and also ensures the normal operation of the delivery.

[0083] To prevent the surgical clip 06 from shifting during ejection, resulting in inaccurate ligation of blood vessels or other tissues, such as... Figure 6 , Figures 9 to 13 As shown, the front end of the clamping rod 04 is a hollow cuboid. The push clamp spring 08 slides in the middle and rear section of the clamping rod 04. When it is installed inside the clamping rod 04, the two together also form a hollow cuboid. The surgical clamp 06 is placed between the two. Four anti-deviation guide blocks 045 are arranged in sequence on the outer side of the four tube walls of the clamping rod 04 facing the jaw of the clamp head 05. The surgical clamp 06 is placed in the clamping rod 04 and pushed towards the clamp head 05. When pushed to the clamp head 05, it first contacts the anti-deviation guide block 045. Under the guiding action of the anti-deviation guide block 045, it returns to the middle of the clamp head 05, thereby effectively preventing the surgical clamp 06 from shifting when it is pushed out, which would lead to inaccurate clamping of blood vessels and improve the safety of the operation.

[0084] Preferably, the specific structural configuration of the anti-deviation guide block 045 is as follows: Figure 6 , Figures 9 to 13As shown, the two sets of anti-deviation guide blocks 045 symmetrically arranged on the upper and lower tube walls of the clamping rod 04 are rectangular in shape. Their rectangular structure matches the overall long and flat structure of the surgical clip 06, so that the two sets of anti-deviation guide blocks 045 on the upper and lower tube walls can better guide and center the surgical clip 06, preventing the surgical clip 06 from deviating when it is pushed out for use.

[0085] Preferred, such as Figure 6 , Figures 9 to 13 As shown, the two sets of anti-deviation guide blocks 045 symmetrically arranged on the left and right tube walls of the clamping rod 04 are triangular in shape. The triangular shape matches the overall elongated and flat structure of the surgical clip 06, thereby enabling the two sets of anti-deviation guide blocks 045 on the left and right tube walls to better guide and center the surgical clip 06, preventing the surgical clip 06 from deviating during the process of being pushed out and used. The triangular shape not only achieves guidance but also saves production costs.

[0086] Preferred, such as Figures 9 to 16 As shown, in order to further prevent the surgical clip 06 from retracting due to obstruction or other factors when it is pushed out of the clamping rod 04, a downwardly curved anti-retraction hook 046 is formed on the upper tube wall of the clamping rod 04. The lowest point of the anti-retraction hook 046 is lower than the highest point of the upper clamping arm of the surgical clip 06 inside the clamping rod 04, so that the anti-retraction hook 046 abuts against the back of the upper clamping arm of the surgical clip 06, thereby pressing the upper clamping arm of the surgical clip 06 and further preventing the surgical clip 06 from retracting due to obstruction or other factors when it is pushed out of the clamping rod 04.

[0087] To prevent the forceps head 05 from shifting during use, which could lead to insufficient precision in extending and securing the surgical clip 06 to blood vessels or other tissues, such as... Figure 5 and Figure 17As shown, this surgical clamp ligation forceps also includes an anti-deviation spring plate 044 disposed on one of the outer walls of the clamping rod 04 and connected to the clamp head 05. The clamp head 05 includes an upper clamp head 051 rotatably disposed on one of the outer walls of the clamping rod 04, and a lower clamp head 052 rotatably disposed on the outer wall of the clamping rod 04 and disposed opposite to the upper clamp head 051. The anti-deviation spring plate 044 includes an anti-deviation spring plate disposed on the outer wall of the clamping rod 04. The main anti-deviation spring 0441, an upper anti-deviation limiting spring 0442 formed on the anti-deviation main spring 0441 and extending towards the pliers 05 and connected to the upper pliers 051, and a lower anti-deviation limiting spring 0443 formed on the anti-deviation main spring 0441 and extending towards the pliers 05 and connected to the lower pliers 052, the upper anti-deviation limiting spring 0442 and the lower anti-deviation limiting spring 0443 are brought together together without external force applied. During the process of the clamping rod 04 driving the upper jaw 051 and the lower jaw 052 to converge, the tail end of the upper jaw 051 tilts upward, thereby pushing the upper anti-deviation limiting spring 0442 pressing against the tail end of the upper jaw 051 upward, and the tail end of the lower jaw 052 tilts downward, thereby pushing the lower anti-deviation limiting spring 0443 pressing against the tail end of the lower jaw 052 downward. The upper anti-deviation limiting spring 0442 and the lower anti-deviation limiting spring 0443 provide the... The forceps head 05 has an opening reaction force, which provides a certain buffer during the closing process, preventing the problem of inaccurate ligation of blood vessels due to excessively fast closing speed. Furthermore, the closing and opening stroke of the forceps head 05 is limited by the distance between the upper anti-deviation limiting spring 0442 and the upper end of the clamping rod 04, and the distance between the lower anti-deviation limiting spring 0443 and the lower end of the clamping rod 04, thereby limiting the closing and opening stroke of the forceps head 05 and preventing the forceps head 05 from opening excessively. Furthermore, the upper anti-deviation limiting spring 0442 is connected to the upper clamp head 051, and the lower anti-deviation limiting spring 0443 is connected to the lower clamp head 052, thereby limiting the upper clamp head 051 and the lower clamp head 052 in the left-right and up-down directions. This prevents the clamp head 05 from deviating during the operation, which could lead to a large error in the position of the surgical clip 06 clamping the blood vessel. This effectively improves the ligation accuracy of the ligation forceps and enhances the safety of the operation.

[0088] Regarding the specific method by which the upper anti-deviation limiting spring 0442 limits the upper clamp head 051, as follows: Figure 5 and Figure 17As shown, the upper anti-deviation limiting spring 0442 has an upper anti-deviation pressing plate 04421 formed at one end near the upper jaw 051, which bends upward to press and limit the upper jaw 051. Through this bent structure, the upper jaw 051 can more easily drive and open the upper anti-deviation pressing plate 04421 when closing. The upper anti-deviation pressing plate 04421 can also more easily use its own elastic restoring force as a buffer reaction force to cushion the closing force of the upper jaw 051. To prevent the problem of inaccurate ligation of blood vessels due to excessively fast convergence speed, the bent structure makes the connection between the upper anti-deviation pressure plate 04421 and the upper clamp head 051 more compact and robust. This allows the upper anti-deviation limiting spring plate 0442 to effectively limit the upper clamp head 051 in the left-right and up-down directions, preventing the clamp head 05 from shifting during the operation and causing a large error in the position of the surgical clamp 06 ligating the blood vessel. This effectively improves the ligation accuracy of the ligation forceps and enhances the safety of the operation.

[0089] Regarding the specific method by which the lower anti-deviation limiting spring 0443 limits the lower clamp head 052, as follows: Figure 5 and Figure 17 As shown, the lower anti-deviation limiting spring 0443 has a downwardly bent lower anti-deviation pressing plate 04431 at one end near the lower jaw 052, which presses and limits the lower jaw 052. This bent structure makes it easier for the lower jaw 052 to drive and open the lower anti-deviation pressing plate 04431 when closing. The lower anti-deviation pressing plate 04431 can also more easily use its own elastic restoring force as a buffer reaction force to cushion the closing force of the lower jaw 052. To prevent the problem of inaccurate ligation of blood vessels due to excessively rapid convergence speed, the bent structure makes the connection between the lower anti-deviation pressure plate 04431 and the lower clamp head 052 more compact and robust. This allows the lower anti-deviation limiting spring plate 0443 to effectively limit the lower clamp head 052 in both the left-right and up-down directions, preventing the clamp head 05 from shifting during the operation and causing a large error in the position of the surgical clip 06 clamping the blood vessel. This effectively improves the ligation accuracy of the ligation forceps and enhances the safety of the operation.

[0090] The specific method by which the upper anti-deviation limiting spring 0442 limits the stroke of the upper clamp head 051 is as follows: Figure 5 and Figure 17As shown, the upper anti-deviation limiting spring 0442 has an upper inclined relief surface that extends from the anti-deviation main spring 0441 to the lower clamp head 052. By setting the upper inclined relief surface to extend from the anti-deviation main spring 0441 to the lower clamp head 052, the upper inclined relief surface of the upper anti-deviation limiting spring 0442 presses against the inner wall of the outer sleeve 07 when it is opened by the upper clamp head 051. Its shape is more in line with the rotating structure, making it easier for the upper anti-deviation limiting spring 0442 to be opened and to limit the upper clamp head 051. This effectively avoids problems such as the long strip shape getting stuck on other parts during rotation, which is not conducive to cooperation, and improves the working accuracy of the anti-deviation structure of the clamp head 05 of the continuous ligation clamp.

[0091] The specific method by which the lower anti-deviation limiting spring 0443 limits the stroke of the lower clamp head 052 is as follows: Figure 5 and Figure 17 As shown, the upper surface of the lower anti-deviation limiting spring 0443 has a lower inclined relief surface that extends in an inclined manner from the anti-deviation main spring 0441 to the upper clamp head 051. By setting the lower inclined relief surface to extend in an inclined manner from the anti-deviation main spring 0441 to the upper clamp head 051, the lower inclined relief surface of the lower anti-deviation limiting spring 0443 presses against the inner wall of the outer sleeve 07 when it is opened by the lower clamp head 052. Its shape is more in line with the rotating structure, making it easier for the lower anti-deviation limiting spring 0443 to be opened and to limit the lower clamp head 052. This effectively avoids problems such as the long strip shape getting stuck on other parts when rotating, which is not conducive to cooperation, and improves the working accuracy of the anti-deviation structure of the ligator head 05 of this continuous ligation clamp.

[0092] Regarding the connection method between the upper clamp head 051 and the upper anti-deviation limiting spring 0442, as follows: Figure 5 and Figure 17 As shown, one side of the upper clamp head 051 has an upper clamp limiting piece 0511 extending horizontally towards the handle 02. The upper anti-deviation pressing piece 04421 presses against the upper clamp limiting piece 0511. By setting the upper clamp limiting piece 0511 to a structure extending horizontally towards the handle 02, the upper clamp limiting piece 0511 is pressed and limited from the top by the upper anti-deviation pressing piece 04421, while the upper clamp head 051, which has an overall inclined and bent structure, is extended and driven by the upper clamp head 051. This facilitates the upper anti-deviation pressing piece 04421 to limit the stroke of the upper clamp head 051 and to limit its movement in the left-right and up-down directions. This prevents the clamp head 05 from deviating during the operation, which could lead to a large error in the position of the surgical clamp 06 clamping the blood vessel. This effectively improves the ligation accuracy of the ligation forceps and enhances the safety of the operation.

[0093] Regarding the connection method between the lower clamp head 052 and the lower anti-deviation limiting spring 0443, as follows: Figure 5 and Figure 17 As shown, a lower clamp head 052 has a lower clamp limiting piece 0521 extending horizontally towards the handle 02 on one side. The lower anti-deviation pressing piece 04431 presses against the lower clamp limiting piece 0521. By setting the lower clamp limiting piece 0521 to extend horizontally towards the handle 02, the lower clamp limiting piece 0521 is pressed and limited from the lower end by the lower anti-deviation pressing piece 04431. At the same time, the lower clamp head 052, which has an overall inclined and bent structure, is extended and driven by the lower clamp head 052. This facilitates the lower anti-deviation pressing piece 04431 to limit the stroke of the lower clamp head 052 and limit its movement in the left-right and up-down directions. This prevents the clamp head 05 from deviating during the operation, which could lead to a large error in the position of the surgical clamp 06 clamping the blood vessel. This effectively improves the ligation accuracy of the ligation forceps and enhances the safety of the operation.

[0094] Regarding the structural configuration on the other side of the clamp head 05, as follows: Figure 18 and Figure 19 As shown, a V-shaped closing spring plate 12 is provided on the outer wall of the front end of the clamping rod 04 away from the anti-deviation spring plate 044. The two arms of the closing spring plate 12 are placed between the upper clamp head 051 and the lower clamp head 052 on the side away from the anti-deviation spring plate 044, so that the two arms of the closing spring plate 12 open the side of the lower clamp head 052 away from the anti-deviation spring plate 044 and the side of the upper clamp head 051 away from the anti-deviation spring plate 044, thereby closing the upper clamp head 051 and the lower clamp head 052, providing the power for the clamp head 05 to close.

[0095] To help users better understand how to use this surgical clip 06 consecutive ligation forceps, such as... Figures 1 to 5 , Figures 20 to 24As shown, an excitation block 011 is formed inside the fixed handle 01, which is arc-shaped and on the rotation trajectory of the handle 02. Several excitation steps 0111 are formed at one end of the excitation block 011 facing the handle 02. An excitation movable plate 021 is formed on the handle 02, which extends horizontally to the rear. An excitation movable step 022 extends laterally from the tail end of the excitation movable plate 021. The excitation movable plate 021 does not contact the excitation block 011. The excitation movable step 022 slides on the several excitation steps 0111. When the handle 02 is pushed, it drives the activation plate 021 to rotate towards the clamp head 05, causing the activation step 022 on the activation plate 021 to press against the activation step 0111 and slide across several activation steps 0111. This provides the user with a tactile feedback, indicating that the clamping process has achieved the desired activation control. The step shape of the activation steps 0111 allows the user to judge the tightening progress of the surgical clamp 06 through this tactile feedback, facilitating control over the clamping and improving the accuracy of the clamping of blood vessels and other tissues, thus aiding in the surgical procedure. After the activation step 022 slides past the activation step 0111, the user continues to press the handle 02, causing it to rotate further. This causes the activation plate 021 and activation steps 022 to reach the highest point of the activation block 011, where they reset and await the next use. The specific reset method is as follows: after the handle 02 is released by the user, its elastic reset force drives the activation plate 021 and activation step 022 to rotate backward, causing the activation step 022 to bypass the top of the activation block 011 and reach the back of the activation block 011, and then slide down along the back of the activation block 011 to the initial position, completing the reset. Because the activation plate 021 does not contact the activation block 011, only the activation step 022 contacts the activation block 011, thus effectively preventing the activation plate 021 from pressing against the activation block 011 and causing it to fail to reset. The whole process is simple and clear, with a simple structure, facilitating cooperation. Furthermore, the shape of the activation step 0111 prevents the activation step 022 from retracting, thus effectively preventing the surgical clip 06 from suddenly falling off.

[0096] Regarding the specific method of resetting the handle 02, as follows: Figure 5 , Figure 15 As shown, the handle 02 can be reset by springs, spring sheets, etc. The reset method is a conventional technical means in the field, so it will not be described in detail in this embodiment.

[0097] For other structural settings on the excitation block 011, such as Figure 22As shown, the end of the excitation block 011 facing the handle 02 also has a confirmation step 0112 located at the upper end of the excitation step 0111, and a reset step 0113 located at the end of the excitation block 0111 away from the excitation step 0111. After the handle 02 drives the excitation movable plate 021 and the excitation movable step 022 set on the excitation movable plate 021 to slide through all the excitation steps 0111, it slides upward into the confirmation step 0112. At this time, the handle 02 pushes the clamping rod 04 to close the clamp head 05, thereby tightening the surgical clamp 06 onto the blood vessel. The tactile feedback of the confirmation step 0112 reminds the user that the clamping action of the surgical clamp 06 has been completed, which helps the user to control the clamping status of the surgical clamp 06. The user continues to push the handle 02, which causes the activation plate 021 and the activation step 022 on the activation plate 021 to slide upward on the activation block 011 until they enter the reset step 0113. The tactile feedback of the reset step 0113 reminds the user that they have pressed to the end and the ligation forceps are about to reset, further facilitating the user's control over the tightness of the surgical clamp 06.

[0098] Preferred, such as Figure 22 As shown, to help users better distinguish between activation and ligation, the step width of the confirmation step 0112 is greater than that of the activation step 0111. This makes the step of the activation step 022 when passing over the confirmation step 0112 more pronounced than that of the activation step 0111, thus allowing users to better distinguish between activation and ligation, and further facilitating user control over the tightness of the surgical clip 06.

[0099] Preferred, such as Figure 22 As shown, to allow users to better distinguish whether the ligation is in place or about to be reset, the step width of the reset step 0113 is greater than that of the activation step 0111. There is no step between the reset step 0113 and the confirmation step 0112, and the distance between the reset step 0113 and the confirmation step 0112 is relatively large. This makes the activation step 022 move smoothly and without any jamming sensation from the activation step 0111 to the confirmation step 0112, and there is a clear sense of segmentation after reaching the confirmation step 0112. This allows users to better distinguish whether the ligation forceps are in an activated state, whether the ligation is in place, or whether they are about to be reset, further facilitating the user's control over the tightness of the surgical clip 06.

[0100] Regarding the specific manner in which the activation step 022 slides on the activation block 011, as follows: Figure 22As shown, the shape of the activation step 022 matches that of the activation step 0111. The protruding structure of the step extends towards the activation block 011. The protruding position is driven by the handle 02 to sequentially enter the activation step 0111, the confirmation step 0112, and the reset step 0113, thereby transmitting the segmented feeling generated by the collision between the activation step 0111, the confirmation step 0112, and the reset step 0113, which is beneficial for the user to control the tightness of the surgical clip 06.

[0101] Preferred, such as Figure 22 As shown, the excitation step 0111, confirmation step 0112, and reset step 0113 are all inclined upwards on the excitation block 011, which better matches the rotation trajectory of the handle 02 driving the excitation movable plate 021 and the excitation movable step 022. This allows the excitation movable step 022 to slide better and more smoothly on the excitation step 0111, confirmation step 0112, and reset step 0113, which is beneficial to the normal operation of the control device of the excitation handle 02 of the continuous ligation forceps.

[0102] To better reset the control device of the trigger handle 02 of this breech-loading ligator, such as... Figure 22 As shown, the back side of the end of the excitation block 011 near the reset step 0113 has a gentler curvature than the back side of the excitation step 0111 and the confirmation step 0112. This makes it easier for the excitation active step 022 to pass over the top of the excitation block 011 and reach the back side of the excitation block 011, thereby improving the reset efficiency and accuracy of the control device for the excitation handle 02 of the continuous ligation forceps.

[0103] Preferred, such as Figure 20 and Figure 21 As shown, the outer wall of the fixed handle 01 is provided with an indicator ruler 13 that matches the activation step 0111, the confirmation step 0112, and the reset step 0113. The outer wall of the handle 02 is provided with a first indicator arrow 023 pointing to the indicator ruler 13. As the first indicator arrow 023 rotates with the handle 02, it points to different parts of the indicator ruler 13, allowing the user to determine whether the ligation forceps are in an activated state, in place, or about to be reset, even from the outside of the ligation forceps. This further facilitates the user's control over the tightness of the surgical clip 06.

[0104] Regarding the specific structural design of the marking ruler 13, as follows: Figure 20 and Figure 21As shown, the marking ruler 13 includes length marking blocks 131 that match the activation step 0111, confirmation step 0112, and reset step 0113 respectively, marking text 112 set on the length marking blocks 131, and a second marking arrow 113 set below the length marking blocks 131. The length marking blocks 131 can be matched according to the step span of the activation step 0111, so that the user can know which activation step(s) 0111 they have rotated to from the external marking ruler 13. The marking text 112 can be set individually on the length marking blocks 131 corresponding to the confirmation step 0112 or the reset step 0113, so that the user knows whether they have rotated to the position where the surgical clip 06 is clamped or the position where they are about to be reset, further facilitating the user's control over the clamping status of the surgical clip 06. Alternatively, each length marking block 131 can be set with a marking text 112, which is more conducive to the user's observation. Similarly, the second indicator arrow 113 points towards the handle 02. It can be individually set on the length indicator block 131 corresponding to the confirmation step 0112 or the reset step 0113, so that the user knows whether it has been rotated to the position where the surgical clip 06 is clamped or is about to be reset. The first indicator arrow 023 and the second indicator arrow 113 point to each other, so that the user can better control the clamping status of the surgical clip 06. It can also be set with a second indicator arrow 113 under each length indicator block 131, so that the user can better observe.

[0105] To improve the efficiency of the push clip 08 in pushing out the surgical clip 06, such as Figures 25 to 27 As shown, the surgical clamp 06 ligation forceps also includes an upper support member 09 disposed between one outer wall of the clamping rod 04 and the outer sleeve 07. The upper support member 09 has at least one radially extending rib 091 formed on its inner wall facing the clamping rod 04, and the rib 091 is generally semi-circular. When the push clamp spring 08 is pushed forward by the push-pull rod 03, the push clamp spring 08 slides on the rib 091. By setting the rib 091 to a semi-circular structure, the contact area between the rib 091 and the push clamp spring 08 changes from a surface contact to a point contact. This results in a smaller contact area and less friction, effectively preventing excessive friction between the push clamp spring 08 and the upper support member 09, which could cause it to become stuck and unable to slide out of the ligation forceps. This improves the smoothness of the clamping rod 04's movement within the upper support, facilitating the precise ejection of the surgical clamp 06 from the clamping rod.

[0106] Preferred, such as Figure 27As shown, two sets of ribs 091 are formed on the upper support member 09. The two sets of ribs 091 are respectively set on the upper end and lower end of the inner wall of the upper support member 09, so that the upper end and lower end of the outer wall of the push clamp spring 08 press against the two sets of ribs 091 respectively. The friction force on the upper end and lower end of the push clamp spring 08 is uniform, effectively preventing the problem of unilateral displacement.

[0107] Regarding the specific structural design of the outer sleeve 07 Figures 1 to 4 As shown, the outer sleeve 07 is a hollow cylinder, and the clamping rod 04, the push clamping spring 08, and the upper support 09 are arranged in its hollow position. Its cylindrical shape is more conducive to performing actions in the micro-incision of minimally invasive surgery, which is beneficial to the operation.

[0108] Preferably, the diameter of the outer tube 07 is 9-10 mm, and more preferably, the diameter of the outer tube 07 is 9.5 mm, which is more in line with the use of minimally invasive techniques in minimally invasive surgery.

[0109] Regarding the specific manner in which the upper support member 09 is disposed on the outer sleeve 07, as follows: Figures 25 to 27 As shown, the upper support 09 extends outward from the end away from the clamping rod 04 to form a semi-circular structure that matches the outer sleeve 07. This allows the upper support 09 to be stably pressed against the cylindrical outer sleeve 07, thus limiting the square clamping rod 04 during transmission. This prevents the clamping rod 04 from shifting in the outer sleeve 07, which could cause the surgical clip 06 to be unable to be accurately transmitted to the forceps head 05. This facilitates the precise ejection of the surgical clip 06 from the clamping rod 04.

[0110] Regarding the specific method of fixing the upper support member 09 to prevent displacement, as follows: Figures 25 to 27 As shown, the upper support member 09 has a hollow upper support limiting block 092 with a semi-arc cross-section at its tail end. A rotating pin 14 passes through the upper support limiting block 092. The rotating pin 14 passes through the upper support limiting block 092 and is engaged in the fixed handle 01, thereby limiting the upper support member 09 to the fixed handle 01 and preventing the upper support member 09 from shifting.

[0111] Preferred, such as Figures 25 to 26 as well as Figure 28As shown, to better limit the clamping rod 04, this surgical clamp 06 ligation forceps also includes a lower support member 10 disposed between the clamping rod 04 and the outer sleeve 07 and symmetrical to the upper support member 09. The upper support member 09 and the lower support member 10 perform a relative clamping and limiting action on the clamping rod 04 and the push clamp spring 08, thereby making it less likely for the clamping rod 04 and the push clamp spring 08 to shift within the outer sleeve 07, facilitating the precise ejection of the surgical clamp 06 from within the clamping rod 04.

[0112] Preferred, such as Figures 1 to 4 As shown, a rotating head 15 can also be provided on the fixed handle 01. The rotating pin 14 is inserted into the inner wall of the rotating head 15, thereby driving the clamping rod 04, the push clamping spring 08, etc. to rotate with the rotating head 15, so that the surgical clamp 06 can be rotated to different angles, which is conducive to the operation.

[0113] Regarding the specific manner in which the lower support member 10 is disposed on the outer sleeve 07, as follows: Figures 25 to 26 as well as Figure 28 As shown, the lower support member 10 extends outward from the end away from the clamping rod 04 to form a semi-circular structure that matches the outer sleeve 07. This allows the lower support member 10 to be stably pressed against the cylindrical outer sleeve 07, thereby limiting the position of the square clamping rod 04 during transmission. This prevents the clamping rod 04 from shifting in the outer sleeve 07, which could cause the surgical clip 06 to be unable to be accurately transmitted to the forceps head 05. This facilitates the accurate ejection of the surgical clip 06 from the clamping rod 04.

[0114] Regarding the specific method of fixing the lower support member 10 to prevent displacement, as follows: Figures 25 to 26 as well as Figure 28 As shown, the lower support member 10 has a hollow lower support limiting block 101 at its tail end, which has a semi-arc cross-section and matches the upper support limiting block 092. The rotating pin 14 passes through the upper support limiting block 092 and the lower support limiting block 101 in sequence and is engaged in the fixed handle 01 at both ends, thereby limiting the lower support member 10 and the upper support member 09 on the fixed handle 01 and preventing the upper support member 09 and the lower support member 10 from shifting. The upper support limiting block 092 and the lower support limiting block 101 are engaged to form a hollow cylinder. The clamping rod 04 and the push clamp spring 08 are placed in the hollow position of the cylinder, thereby effectively limiting the clamping rod 04 and the push clamp spring 08, preventing the clamping rod 04 from shifting in the outer tube 07 and causing the surgical clip 06 to be unable to be accurately delivered to the forceps head 05, thus facilitating the accurate ejection of the surgical clip 06 from the clamping rod 04.

[0115] To further improve the smoothness of the push clip 08 in advancing the surgical clip 06, such as... Figure 5 , Figure 15 , Figures 29 to 31 As shown, the surgical clamp 06 ligation forceps also includes a support bar 11 disposed within the push-pull rod 03 and pushing the push clamp spring 08. The upper and lower ends of the support bar 11 are each formed with several protrusions 111 that are sequentially arranged and protrude towards the inner wall of the clamping rod 04. When the support bar 11 pushes the push clamp spring 08 out, the protrusions 111 on the support bar 11 press against the upper and lower inner walls of the clamping rod 04 respectively, thereby changing the contact between the support bar 11 and the clamping rod 04 from surface contact to point contact, effectively reducing the contact area, improving the smoothness of the support bar 11 pushing the push clamp spring 08 forward, and facilitating the precise ejection of the surgical clamp 06 from the clamping rod 04.

[0116] Regarding the specific manner in which the push clip spring 08 is pushed out by the support bar 11, such as Figure 7 as well as Figure 30 and Figure 31 As shown, a push clamp limiting groove 112 is formed on the side of the support bar 11 away from the clamping rod 04 for the push clamp spring 08 to be inserted. A push clamp limiting block 083 is formed on the side of the push clamp spring 08 facing the support bar 11, which protrudes inward and slides in the push clamp limiting groove 112. The push clamp limiting block 083 slides in the push clamp limiting groove 112 and is limited in the vertical direction by the push clamp limiting groove 112, thereby effectively preventing the push clamp spring 08 from deviating during the process of being driven to move, which is conducive to accurately pushing out the surgical clamp 06 in the clamping rod 04.

[0117] Regarding the specific method by which the support bar 11 will not shift when pushed by the push-pull rod 03, such as Figure 30 and Figure 31 As shown, the support bar 11 has a first push-limiting groove 113 extending radially toward the push-pull rod 03 at one end. The rotating pin 14 passes through the first push-limiting groove 113 and the clamping rod 04 and then gets stuck on the inner wall of the fixed handle 01. When the push-pull rod 03 is pushed, the first push-limiting groove 113 in the support bar 11 moves forward and backward relative to the rotating pin 14 fixed on the inner wall of the fixed handle 01, thereby limiting the stroke of the first push-limiting groove 113 and preventing the support bar 11 from shifting when pushed by the push-pull rod 03.

[0118] Preferred, such as Figure 7 as well as Figure 30 and Figure 31As shown, in order to synchronously push the push clamp spring 08, the tail end of the push clamp spring 08 is formed with a second push limiting groove 084 that matches the first push limiting groove 113. The rotating pin 14 passes laterally through the second push limiting groove 084, the first push limiting groove 113, and the clamping rod 04 in sequence and then gets stuck on the inner wall of the fixed handle 01. When the push-pull rod 03 is pushed, the first push limiting groove 113 in the support bar 11 and the second push limiting groove 084 on the push clamp spring 08 move forward and backward relative to the rotating pin 14 fixed on the inner wall of the fixed handle 01, thereby achieving the stroke limiting function of the first push limiting groove 113 and the second push limiting groove 084, preventing the support bar 11 and the push clamp spring 08 from shifting during the pushing process, and at the same time achieving synchronous limiting of the support bar 11 and the push clamp spring 08, which is beneficial for the support bar 11 to drive the push clamp spring 08.

[0119] Regarding the length settings of the first push limiting groove 113 and the second push limiting groove 084, the lengths of the first push limiting groove 113 and the second push limiting groove 084 are equal to the distance between the two sets of surgical clips 06 inside the clamping rod 04, so that the limiting stroke of the rotating pin 14 on the support bar 11 and the push clip spring 08 is the stroke to push out a set of surgical clips 06, which is conducive to accurately pushing out each set of surgical clips 06 respectively.

[0120] Preferred, such as Figure 7 as well as Figure 30 and Figure 31 As shown, in order to enable the push-pull rod 03 to better push the push clamp spring 08, the tail end of the push clamp spring 08 is formed with a support linkage limiting block 085 that bends toward the inner wall of the clamping rod 04 and presses and limits the tail end of the support bar 11. While the push-pull rod 03 pushes the support bar 11, the support linkage limiting block 085 presses against the tail end of the support bar 11, improving the linkage between the support bar 11 and the push clamp spring 08, thereby enabling the push-pull rod 03 to better push the push clamp spring 08 and facilitating the cooperation between the components.

[0121] Regarding the specific arrangement of the support bar 11 and the push clip spring 08 within the push-pull rod 03, as follows: Figure 7 as well as Figures 30 to 32 As shown, the push-pull rod 03 has an inwardly extending push-pull embedding groove 031 at one end near the support bar 11, into which the support bar 11 and the push clamp spring 08 are embedded. By having the support bar 11 and the push clamp spring 08 correspondingly embedded in the push-pull embedding groove 031, the push-pull rod 03 can stably drive the push clamp spring 08 and the support bar 11 to push out and retract to reset, ensuring the normal operation of the ligation forceps.

[0122] Regarding the specific manner in which the support bar 11 and the push clip spring 08 are driven within the push-pull rod 03, as follows: Figure 30 and Figure 31 As shown, a push-pull fixing hole 114 is vertically provided at one end of the support bar 11 near the push-pull rod 03. The push-pull pin 16 passes through the push-pull rod 03 and the push-pull fixing hole 114 to fix the push-pull rod 03 and the support bar 11 in the push-pull embedding groove 031. This enables the push-pull rod 03 to stably drive the push clamp spring 08 and the support bar 11 to push out and retract, which is beneficial to the cooperation between the components.

[0123] Regarding the reset method of the support bar 11 within the push-pull rod 03, a spring can be provided between the tail end of the support bar 11 and the inner wall of the push-pull rod 03, so that the support bar 11 can be reset by the spring when it moves.
