Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a clamping chamber, a clamping device, and an applicator. Background Technology

[0002] During surgical procedures, to fully expose the surgical field, it is necessary to ligate the blood vessels surrounding the target tissue to stop bleeding. Hemostasis has become one of the core basic surgical techniques. Almost every surgical procedure on any part of the human body involves bleeding and hemostasis, and generally, a clamping device is used to ligate and close the wound to stop the bleeding.

[0003] Currently, the clamping chambers of clamping devices on the market are all manufactured using sheet metal processing. Due to the long length of the clamping chamber, the small size in the left and right directions, and the relatively complex structure of the clamping chamber, the yield rate of clamping chambers produced by sheet metal processing is low, resulting in high costs for clamping chambers. Summary of the Invention

[0004] (a) Technical problems to be solved

[0023] (III) Beneficial Effects

[0024] The beneficial effects of this invention are:

[0025] 1. By placing the metal clamping section at the far end of the clamping chamber, and providing at least one first elastic clip on the bottom plate of the metal clamping section, and placing the plastic clamping section near the first elastic clip at the nearest end of the metal clamping section, this ensures sufficient length of the metal clamping section for mounting accessories such as jaws and firing mechanisms, allowing the clamping chamber with the accessories mounted to pass smoothly through piercing devices of existing specifications. On the other hand, by using the combination of the plastic and metal clamping sections, the length of the metal clamping section processed by sheet metal is reduced, overcoming the technical problem of low yield caused by the entire clamping chamber being made of metal, thereby increasing the yield of the clamping chamber and reducing costs.

[0026] 2. The present invention designs a novel plastic clamping compartment and a split elastic card. The mounting piece on the split elastic card cooperates with the third slot, fixing cavity and fixing post on the plastic clamping compartment to fix the split first elastic card on the plastic clamping compartment.

[0027] 3. By setting a buckle platform protruding into the compartment at the far end of the bottom plate of the plastic compartment, which cooperates with the buckle hole opened at the near end of the bottom plate of the metal compartment, the far end of the plastic compartment and the near end of the metal compartment are snapped together, and the connection is stable.

[0028] 4. By providing at least one boss in the middle of the left and right directions of the bottom plate of the plastic clamping compartment along the clamping direction, and providing at least one boss in the middle of the left and right directions of the bottom plate of the metal clamping compartment along the clamping direction, the boss supports the closed tail of the ligation clamp during the clamping process, reducing the up and down swing of the closed tail of the ligation clamp during the clamping process, which is conducive to pushing the clamping piece to clamp, making the clamping stable and reducing the situation of clamping jamming.

[0029] 5. By setting the clamping boss, and setting the first elastic clamping plate, the second elastic clamping plate and the clamping platform on the top plate of the metal clamping compartment, the ligation clamping clamp is stable and clamping failure is avoided.

[0030] 6. By setting an elastic aligning plate, during the insertion of the clamp into the clamp, the elastic aligning plate will align the closed tail of the clamp into the center position inside the clamp chamber, so that the head of the pusher plate can effectively act on the closed tail of the clamp, stabilize the clamping, and avoid clamping failure.

[0031] 7. By setting a V-shaped pusher, not only can the clamp to be inserted be pushed, but the closed tail of the clamp to be inserted can also be aligned to the center position inside the clamp chamber, so that the V-shaped pusher can act well on the closed tail of the clamp to be inserted, and the clamping can be stably delivered.

[0070] It should be noted that in this article, "near" refers to the side closer to the operator, and "far" refers to the side closer to the patient. The directional terms "upper," "lower," "front," "back," "left," and "right" used in this article are... Figure 3 The orientation is for reference only. The invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0071] Example 1

[0072] Commonly used ligation clips such as Figure 1As shown, the ligation clip includes a V-shaped ligation clip body 1. The V-shaped ligation clip body 1 generally includes a first clamping arm 11 and a second clamping arm 12 connected together. One end of the two clamping arms is connected to form the closed tail of the ligation clip, and the other end is a free end. The free ends of the two clamping arms are far apart, forming a V-shape. Preferably, the V-shaped ligation clip body 1 is integrally formed from the first clamping arm 11 and the second clamping arm 12. The free end of the first clamping arm 11 is provided with an inwardly curved locking hook 111, and the free end of the second clamping arm 12 is provided with a hook groove 121 adapted to the locking hook 111. To facilitate the clamping of the ligation clip by the jaws 9 of the clamp applicator, a first clamping post 21 is provided on the first clamping arm 11 near the locking hook 111 (i.e., near the free end). The height direction of the first clamping post 21 is perpendicular to the side plane of the V-shaped ligation clip body 1, and two first clamping posts 21 are symmetrically located on both sides of the first clamping arm 11. In this embodiment... Figure 1 In this embodiment, two first clamping posts 21 are connected, but they can also be disconnected. A second clamping post 22 is provided on the second clamping arm 12 near the hook groove 121 (i.e., near the free end). The height direction of the second clamping post 22 is perpendicular to the side plane of the V-shaped ligation clip body 1. Two second clamping posts 22 are symmetrically located on both sides of the second clamping arm 12. In this embodiment, the two second clamping posts 22 are disconnected, with the aforementioned hook groove 121 provided between them. Further, the first clamping arm 11 is an arc protruding outward from the V-shaped ligation clip body 1, and the second clamping arm 12 is an arc protruding inward from the V-shaped ligation clip body 1.

[0073] The clip applicator provided in this embodiment is a continuous-fire applicator capable of delivering clips continuously. The clip magazine of this continuous-fire applicator stores multiple ligation clips. After the applicator fires one ligation clip and closes the clip, it can immediately deliver the next ligation clip to the jaws for the next firing, achieving continuous firing of ligation clips by the applicator. This reduces hemostasis time during surgical procedures and improves surgical efficiency. However, this invention is not limited to this; the improved structure of this invention can also be applied to other types of applicators, which are also within the scope of protection of this invention.

[0074] like Figures 2 to 7As shown, the clamping device of the continuous clamping device includes a clamping chamber for accommodating multiple ligation clips, and also includes a pusher clip 4 for pushing the ligation clips. The multiple ligation clips include a ligation clip 13 (the ligation clip to be inserted into the jaws) located at the farthest end of the clamping chamber and ligation clips arranged and stored near the ligation clip 13; the multiple ligation clips are placed flat on the bottom plate of the clamping chamber with their openings facing the clamping direction; the first clamping arm 11 of the ligation clip is attached to the left side wall of the clamping chamber 3, and the second clamping arm 12 of the ligation clip is attached to the right side wall of the clamping chamber 3; multiple first elastic cards 33 that are evenly spaced along the clamping direction and tilted upwards are arranged on the bottom plate of the clamping chamber; the push clip 4 includes a push clip body 41 and a push clip head connected in sequence; the push clip head is bent to one side relative to the push clip body 41; the push clip body 41 covers the ligation clips other than the ligation clip 13; the push clip head extends into the clamping chamber 3 and is positioned close to the ligation clip 13; multiple third elastic cards 411 that are evenly spaced along the clamping direction and tilted downwards are arranged on the push clip body 41.

[0075] Before the rapid-fire clamp applicator delivers the clamps, the ligation clamp 13 is closer to the far end of the clamping chamber 3 than the farthest first elastic card 33. The clamping posts of the ligation clamps other than the ligation clamp 13 are located between two adjacent first elastic cards 33, and the third elastic card 411 is located between the clamping posts of adjacent ligation clamps other than the ligation clamp 13. When the rapid-fire clamp applicator delivers the clamps, the push clip 4 moves towards the far end of the clamping chamber, and the raised part of the third elastic card 411 gradually abuts against the first clamping post 21 and / or the second clamping post 22 of all ligation clamps other than the ligation clamp 13, while the head of the push clip abuts against the tail of the ligation clamp 13. As the push clip 4 continues to advance towards the distal end of the clamping chamber 3, it pushes all the ligation clips towards the distal end of the clamping chamber 3 until the ligation clip 13 to be inserted enters the jaw 9. The push clip 4 then stops advancing towards the distal end of the clamping chamber 3. During this process, all the ligation clips except the ligation clip 13 to be inserted will pass over their adjacent first elastic card 33 on the distal side. Next, the push clip 4 advances towards the proximal end of the clamping chamber 3. The push clip head and the third elastic card 411 will drive all the ligation clips except the ligation clip 13 to advance towards the proximal end of the clamping chamber 3. When all the ligation clips except the ligation clip 13 to be inserted contact the first elastic card 33, the first elastic card 33 will prevent all the ligation clips except the ligation clip 13 from continuing to advance towards the proximal end of the clamping chamber 3. Because the push clip head and the third elastic card 411 are elastic, the push clip head and the third elastic card 411 will pass over their adjacent ligation clips on the proximal side. After that, the push clip 4 stops advancing towards the proximal end of the clamping chamber 3. The pusher clip 4 moves back and forth, sequentially delivering the ligation clip to the jaws 9.

[0076] Among them, such as Figure 2 and Figure 3As shown, the design of the ligation clip is consistent with the above description and will not be repeated. Based on the above description, the clamping chamber includes a plastic clamping chamber part 31 and a metal clamping chamber part 32. The plastic clamping chamber part 31 and the metal clamping chamber part 32 are connected sequentially along the clamping direction. The proximal end of the metal clamping chamber part is connected to the distal end of the plastic clamping chamber part. Thus, the metal clamping chamber part 32 is located at the distal end of the clamping chamber 3. At least one first elastic card 33 is provided on the bottom plate of the metal clamping chamber part 32. The plastic clamping chamber part 31 is located near the first elastic card 33 at the nearest end of the metal clamping chamber part 32, that is, the distal end of the plastic clamping chamber part 31 is connected to the proximal end of the metal clamping chamber part 32.

[0077] To ensure the strength of the plastic clamping section, the bottom plate and side walls of the manufactured plastic clamping section 31 are thicker than those of the metal clamping section 32. For example... Figure 8 As shown, in actual use, it is also necessary to install jaws 9 and firing mechanism 8 for closing jaws 9 at the far end of the clamping chamber 3. Since the bottom plate and side walls of the plastic clamping chamber 31 are relatively thick, if jaws 9 and firing mechanism 8 are installed on the plastic clamping chamber 31, the overall radial dimension will be increased and it will be unable to pass through the existing specification piercing device. Therefore, the metal clamping chamber 32 is located at the far end of the clamping chamber 3. At least one first elastic card 33 is provided on the bottom plate of the metal clamping chamber 32. The plastic clamping chamber 31 is located near the first elastic card 33 at the nearest end of the metal clamping chamber 32. This ensures that the length of the metal clamping chamber is sufficient for the installation of jaws 9 and firing mechanism 8 and other supporting parts, so that the clamping chamber after the supporting parts are installed can pass through the existing specification piercing device smoothly. On the other hand, by using the combination of plastic clamping chamber 31 and metal clamping chamber 32, the length of the metal clamping chamber 32 processed by sheet metal process is reduced, overcoming the technical problem of low yield caused by the clamping chamber being made entirely of metal, thus improving the yield of the clamping chamber and reducing the cost.

[0078] In this embodiment, as Figure 3 As shown, three first elastic clips 33 are provided on the base plate of the metal clamping section 32. The plastic clamping section 31 is located near the nearest first elastic clip 33 on the metal clamping section 32, and the near end of the plastic clamping section 31 is the near end of the clamping section 3. This arrangement of the metal clamping section length is beneficial for sheet metal processing, while providing sufficient length for the installation of matching parts.

[0079] In this embodiment, at least one first elastic card 33 is also provided on the bottom plate of the plastic clamping compartment 31. The first elastic cards on the metal clamping compartment and the plastic clamping compartment are arranged at equal intervals along the clamping direction, forming the first elastic cards of the clamping compartment as a whole.

[0080] The first elastic card 33 on the plastic clamping compartment 31 is a separate first elastic card 331. The plastic clamping compartment 31 is provided with an installation position, and the separate first elastic card 331 is fixed to the plastic clamping compartment 31 through the installation position. The separate first elastic card 331 is made of metal to facilitate the blocking effect of the first elastic card 33 on the ligation clip. The first elastic card 33 on the bottom plate of the metal clamping compartment 32 is an integral first elastic card 332, and the integral first elastic card 332 is integrally formed with the bottom plate of the metal clamping compartment 32.

[0081] Preferably, such as Figure 9 and Figure 10 As shown, the mounting position includes a fixing cavity 311 and a slot for inserting a separate first elastic card 331 from the outside of the plastic clip section 31 into the inside of the plastic clip section 31. The slot includes a first slot 312 formed in the side wall of the plastic clip section 31, and a second slot 313 and a third slot 314 formed in the bottom plate side of the plastic clip section 31. Figure 9 The dashed lines in the near and far directions indicate the connection points between the side wall and the bottom plate of the plastic compartment. (For example...) Figure 11 As shown, the split-type first elastic card 331 includes a blocking piece 333, a connecting piece 334, and a mounting piece 335. Figure 11 The dotted line in the diagram represents the connection point between the side wall of the plastic clip compartment and the bottom plate of the plastic clip compartment after the split-type first elastic card is inserted. The first end of the blocking piece 333 forms the raised end of the split-type first elastic card 331. The second end of the blocking piece 333 is connected to the first end of the connecting piece 334. The second end of the connecting piece 334 is connected to the first end of the mounting piece 335 at a position away from the insertion end of the mounting piece 334. See also... Figure 10 and Figure 11 The blocking piece 333 is inserted into the first slot 312, the connecting piece 334 is inserted into the second slot 313 extending into the bottom plate of the plastic clamping compartment 31, and the mounting piece 335 is inserted into the third slot 314 extending into the bottom plate of the plastic clamping compartment 31. See also... Figure 12 and Figure 13 A fixing cavity 311 is formed within the bottom plate of the plastic clip portion 31. The fixing cavity 311 is located on the inner end side of the third slot 314 and communicates with the third slot 314. A fixing post 315 is provided within the fixing cavity 311. The protruding end of the fixing post 315 extends outward from the plastic clip portion 31 relative to the plane of the third slot 314. The side of the fixing post 315 facing the third slot 314 includes a guide surface 316, which includes an inclined surface extending from the plane of the third slot to the protruding end of the fixing post along the direction of insertion of the elastic card. A fixing hole 336 is provided on the mounting piece 335 in the direction facing the fixing post 314, and the fixing hole 336 is located near the insertion end of the mounting piece 335.

[0082] During the insertion of the mounting piece 335 into the third slot 314, the insertion end of the mounting piece 335 will abut against the guide surface 316 of the fixing post 315. As the mounting piece 335 continues to be inserted, the insertion end of the mounting piece 335 will advance along the guide surface 316 and undergo elastic deformation until the protruding end of the fixing post 315 falls into the fixing hole 336 and cannot be inserted further. At this time, the blocking piece 333 passes through the first slot 313 and is located inside the plastic clamping part. Figure 13 and Figure 15 As shown. By engaging the mounting plate with the third slot, the fixing cavity, and the fixing post, the split-type first elastic card is fixed on the plastic clamping part.

[0083] Furthermore, in this embodiment, after the mounting piece 335 is inserted into the third slot 314, the mounting piece 335 is parallel to the bottom plate of the plastic clamping part 31, and the protruding end of the fixing post 315 is perpendicular to the plane of the third slot 314 and extends outward from the plastic clamping part 31.

[0084] More preferably, the split-type first elastic card 33 further includes an auxiliary mounting piece 337, the first end of which is connected to the second end of the mounting piece 335 at a position away from the insertion end of the mounting piece, and the auxiliary mounting piece 337 intersects with the mounting piece 335; the slot also includes a fourth slot 317 formed on the side of the bottom plate of the plastic compartment portion, and the auxiliary mounting piece 337 is inserted into the fourth slot 317 extending into the bottom plate of the plastic compartment portion 31. This arrangement makes the split-type first elastic card more stable on the plastic compartment portion 31.

[0085] Furthermore, in this embodiment, the auxiliary mounting piece 337 is perpendicular to the mounting piece 337, and the second end of the auxiliary mounting piece 337 extends outward from the plastic clamping compartment 31.

[0086] Preferably, such as Figure 3 and Figure 4 As shown, a latching platform 318 protruding into the compartment is provided at the far end of the bottom plate of the plastic compartment 31. Second elastic clips 319 are respectively provided on opposite sides of the latching platform 318. The first end of the second elastic clip 319 is connected to the latching platform 318, and the second end of the second elastic clip 319 is a cantilever structure extending downwards beyond the latching platform 318. A latching hole 321 is provided at the near end of the bottom plate of the metal compartment 32, corresponding to the latching platform 318. When an external force is applied to press the latching hole 321 onto the latching platform 318, the latching hole 321 compresses the second elastic clip 319 and passes over it. After the latching hole 321 passes over the second elastic clip 319, the second elastic clip 319 returns to its original shape, and the bottom plate of the metal compartment 32 is latched between the second elastic clip 319 and the bottom plate of the plastic compartment 31. Through the cooperation of the latching platform and the latching hole, a stable and detachable connection between the plastic compartment and the metal compartment is achieved.

[0087] Furthermore, in this embodiment, second elastic cards 319 are respectively provided on the left and right sides of the fastening platform 318, and the first end of the second elastic card 319 is connected to the middle part of the fastening platform 318 in the vertical direction.

[0088] Preferably, a placement groove 37 for accommodating the proximal end of the metal clip 32 is provided at the overlapping position of the plastic clip 31 and the metal clip 32, and a mounting platform 318 is correspondingly provided on the bottom plate of the placement groove 37. This makes the upper surface of the bottom plate of the metal clip 32 approximately coplanar with the upper surface of the bottom plate of the plastic clip 31, the inner surface of the left side wall of the metal clip 32 approximately coplanar with the inner surface of the left side wall of the plastic clip 31, and the inner surface of the right side wall of the metal clip 32 approximately coplanar with the inner surface of the right side wall of the plastic clip 31, facilitating a smooth transition of the ligation clip from the plastic clip 31 to the metal clip 32.

[0089] Preferably, such as Figure 3 and Figure 5 As shown, one or more limiting grooves 34 along the clamping direction are formed at the top of the left side wall of the plastic clamping compartment 31, and one or more limiting grooves 34 along the clamping direction are formed at the top of the right side wall of the plastic clamping compartment 31. The clamping device also includes a pusher plate 4 for pushing the ligation clip. One or more limiting plates 412 are provided at the left side end of the pusher plate body 41, and one or more limiting plates 412 are provided at the right side end of the pusher plate body 41. When the pusher plate 4 pushes the ligation clip, the limiting plates 412 are accommodated in the limiting grooves 34, ensuring the stability of the pusher plate pushing process.

[0090] Preferably, a protrusion 35 extending outward from the bottom plate of the plastic clamping compartment 31 is provided. In this way, after the plastic clamping compartment 31 is installed into the sleeve (not shown in the figure), the protrusion 35 can fill the space below the bottom plate of the plastic clamping compartment 31, preventing the clamping compartment from shaking inside the sleeve.

[0091] The main reasons for the failure of the continuous clamp applicator to jam and deliver clamps during actual use are as follows: 1. Due to the presence of the first and second clamping posts of the clamp, the closed tail of the clamp stored in the clamp chamber is in a suspended state. During the clamp delivery process, the closed tail of the clamp will swing up and down, which is not conducive to pushing the clamp and delivering the clamp, making the clamp delivery unstable, thus causing the clamp delivery to jam. 2. During the process of delivering the ligation clip to the jaws, because the two clamping arms of the ligation clip are arc-shaped and protrude in the same direction, the closed tail of the ligation clip stored in the clamping chamber often tends to be biased towards one side wall of the clamping chamber (in this embodiment, the right side wall of the metal clamping chamber and the right side wall of the plastic clamping chamber), which is not conducive to pushing the head of the clamping piece against the closed tail of the ligation clip to complete the clamping, causing the clamping to fail; 3. During the process of delivering the ligation clip to the jaws, because there is a margin between the ligation clip and the top plate of the clamping chamber, the ligation clip may swing upwards during clamping, which is not conducive to delivering the ligation clip to the jaws, and the clamping is unstable.

[0092] Therefore, in the clamping chamber proposed in this embodiment, at least one boss is provided in the middle of the left-right direction of the bottom plate of the plastic clamping chamber (i.e., the left and right positions of the boss are in the middle of the bottom plate of the plastic clamping chamber), and at least one boss is provided in the middle of the left-right direction of the bottom plate of the metal clamping chamber (i.e., the left and right positions of the boss are in the middle of the bottom plate of the metal clamping chamber). When the ligation clamp is fed along the boss, the top of the boss gradually supports the closed tail of the ligation clamp, so that the closed tail of the ligation clamp is eventually parallel to the plane of the bottom plate of the clamping chamber. In this way, the boss supports the closed tail of the ligation clamp, reduces the up-and-down swing of the closed tail of the ligation clamp during the feeding process, facilitates the feeding of the clamping clip, makes the feeding stable, and reduces the possibility of clamp jamming.

[0093] like Figure 3 As shown, in this embodiment, a protrusion is provided at the center of the bottom plate of the plastic clamp compartment along the clamping direction in the left-right direction. This protrusion is the first clamping protrusion 36. The clamping end of the first clamping protrusion 36 is located near the end of the bottom plate of the plastic clamp compartment, and the clamping end of the first clamping protrusion 36 is located at the far end of the bottom plate of the plastic clamp compartment. Furthermore, the clamping end of the first clamping protrusion 36 is located near the placement groove 37. Thus, the function of the first clamping protrusion is to improve the stability of most of the ligation clips in the plastic clamp compartment as they are pushed to the far end.

[0094] Furthermore, the first clamping boss 36 is integrally formed with the bottom plate of the plastic clamping compartment. This facilitates processing. Furthermore, the top plane of the clamping platform 318 is coplanar with the top plane of the first clamping boss 36. As the ligation clip is fed along the clamping platform 318, the top of the clamping platform 318 gradually supports the closed tail of the ligation clip, so that the plane containing the closed tail of the ligation clip eventually becomes parallel to the plane of the bottom plate of the clamping compartment. Thus, while the clamping platform functions as a clamp, it also supports the tail of the ligation clip fed along the platform, further ensuring the stability of the clamping process.

[0095] like Figure 3 , Figure 6 and Figure 7 As shown, in this embodiment, at least one protrusion provided on the bottom plate of the metal clamping compartment includes an insertion protrusion 322 (a protrusion that enters the jaws). The insertion end of the insertion protrusion 322 is located on the bottom plate of the metal clamping compartment, and the exit end of the insertion protrusion 322 is located at the far end of the bottom plate of the metal clamping compartment and extends out of the bottom plate. Along the direction towards the far end, the top surface of the insertion end extends obliquely and flatly away from the bottom plate of the metal clamping compartment, so as to smoothly guide the tail of the clamping clip 13 to be inserted into the clamping compartment to rise without jamming the clamping clip 13. Of course, it is not limited to this. In other embodiments, the top surface of the insertion end can also be an arc surface. The top surface of the exit end is a plane parallel to the bottom plate of the metal clamping compartment. The top surface of the portion between the insertion end and the exit end is a plane and is flush with the top surface of the exit end.

[0096] During the process of the ligation clamp 13 entering the jaws, the head of the pusher plate needs to press against the closed tail of the ligation clamp 13 to push it into the jaws 9. By providing the clamping boss 322, during the clamping process, the clamping boss 322 can support the tail of the ligation clamp 13, preventing it from swinging up and down. The pusher plate head effectively acts on the closed tail of the ligation clamp 13, ensuring stable clamping. At the same time, by extending the clamping end of the clamping boss 322 out of the bottom plate of the metal clamping compartment, the clamping into the jaws 9 is further stabilized. Of course, in other embodiments of the present invention, the clamping end of the clamping boss can also be flush with the far end of the bottom plate of the metal clamping compartment.

[0097] Therefore, in this embodiment, during the clamping process, the closed tail of the clamping clip 13 to be inserted is supported by the clamping end of the clamping protrusion 322, and the portion between the clamping end and the clamping end, as well as the clamping end, maintains a horizontal posture. In this embodiment, the clamping end of the clamping protrusion 322 is a cantilever structure, but the present invention is not limited to this, and the clamping end of the clamping protrusion 322 can be connected to the clamping chamber bottom plate by a connector.

[0098] Furthermore, the clamping boss 322 is a boss that protrudes into the metal clamping compartment. This facilitates machining.

[0099] Preferably, the metal clamping compartment further includes a top plate, which is located at the far end of the metal clamping compartment. The two sides of the top plate are connected to the two side walls of the metal clamping compartment, respectively. A first elastic clamping piece 323 is provided at the center of the top plate in the left-right direction, curving upwards towards the inside of the clamping compartment along the clamping direction. The first elastic clamping piece 323 corresponds to the clamping end of the insertion boss 322. During clamping, while the closed tail of the clamping clip 13 is supported by the clamping end of the insertion boss 322, the ligation clip body of the clamping clip 13 is pressed by the bottom of the first elastic clamping piece 323. The first elastic clamping piece is used to press the clamping clip inside the clamping compartment, ensuring stable delivery of the clamping clip to the jaws.

[0100] The first elastic clamping plate 323 includes a first connecting portion and a first clamping portion. The plane where the first connecting portion is located is an inclined surface extending into the clamping chamber. The first end of the first connecting portion is connected to the top plate of the metal clamping chamber, and the second end of the first connecting portion is connected to the first end of the first clamping portion. The plane where the first clamping portion is located is parallel to the plane where the bottom plate of the metal clamping chamber is located. As configured above, the clamping contact between the first elastic clamping plate 323 and the clamping clip 13 to be inserted can be increased, making the clamping stable. At the same time, the clamping time of the first elastic clamping plate on the clamping clip to be inserted can be increased.

[0101] More preferably, a second elastic clamping piece 324 is provided at the far center of the top plate of the metal clamping compartment, extending beyond the far end of the top plate of the metal clamping compartment. The second elastic clamping piece 324 is provided corresponding to the exit end of the clamping boss 322. The second elastic clamping piece 324 is raised along the clamping direction and towards the inside of the jaws 9. During the clamping process, when the clamping clip 13 to be clamped is pushed to extend beyond the metal clamping compartment, the clamping clip 13 to be clamped is pressed by the second elastic clamping piece 324. Since the exit end of the clamping boss is located at the far end of the bottom plate of the clamping compartment and extends beyond the bottom plate of the metal clamping compartment, the second elastic clamping piece is used to press the clamping clip to be clamped outside the metal clamping compartment, ensuring stable delivery of the clamping clip to the jaws.

[0102] Specifically, the second elastic clamping plate 324 includes a second connecting portion and a second clamping portion. The plane of the second connecting portion is an inclined surface extending into the metal clamping compartment. The first end of the second connecting portion is connected to the top plate of the metal clamping compartment, and the second end of the second connecting portion is connected to the first end of the second clamping portion. The plane of the second clamping portion is parallel to the plane of the bottom plate of the metal clamping compartment and extends beyond the far end of the bottom plate of the metal clamping compartment. The distance between the first clamping portion and the second clamping portion is less than the length of the ligation clip, thereby providing continuous clamping force to the ligation clip and improving clip delivery stability.

[0103] Preferably, a clamping platform 325 is provided on the side of the top plate of the metal clamping compartment, protruding into the metal clamping compartment along the clamping direction. The clamping platform 325 is positioned corresponding to the clamping boss 322, and the clamping end of the clamping platform 325 is located at the far end of the top plate of the metal clamping compartment. During clamping, while the closed tail of the clamping clip 13 to be clamped is supported by the clamping end of the clamping boss 322, the top clamping post of the clamping clip 13 to be clamped is pressed by the clamping platform 325. This prevents the clamping clip 13 to be clamped from swinging upwards during clamping, ensuring stable clamping. Furthermore, during clamping, while the closed tail of the clamping clip 13 to be clamped is supported by the clamping end of the clamping boss 322, the top clamping post of the clamping clip to be clamped is pressed by the clamping end of the clamping platform 325.

[0104] It is conceivable that a clamping platform 325, protruding into the metal clamping compartment along the clamping direction, is provided on one side of the top plate of the metal clamping compartment. This prevents the clamping clamp to be inserted from tilting upwards during clamping, ensuring stable clamping. Similarly, providing clamping platforms 325 protruding into the metal clamping compartment along the clamping direction on both sides of the top plate of the metal clamping compartment would also prevent the clamping clamp to be inserted from tilting upwards during clamping, ensuring stable clamping.

[0105] In this embodiment, to ensure the stability of the ligation clip insertion, an insertion boss 322 is provided. Based on the cooperative action of the first elastic clamping plate 323, the second elastic clamping plate 324, and the clamping platform 325 provided on the top plate of the metal clamp compartment, the ligation clip to be inserted is pushed smoothly. However, the present invention is not limited to this. The first elastic clamping plate 323 and the second elastic clamping plate 324 can be combined into a single clamping plate, which corresponds entirely to the insertion boss 322. Either the clamping plate or the clamping platform can be selected.

[0106] Furthermore, such as Figure 3 , Figure 6 and Figure 7 As shown, an elastic aligning plate 326 is provided at the far end of the aligning sidewall of the metal clamping compartment. This aligning sidewall is the clamping compartment sidewall biased towards the closed tail of the ligation clamp (in this embodiment, it is the right sidewall of the metal clamping compartment). The elastic aligning plate 326 is tilted upwards towards the interior of the metal clamping compartment along the clamping direction. During the clamping process, the clamping clamp 13 to be inserted is pushed forward, and the closed tail sidewall of the clamping clamp 13 to be inserted comes into contact with the elastic aligning plate 326. As the clamping progresses, the elastic aligning plate 326 aligns the closed tail of the clamping clamp 13 to a position near the center inside the metal clamping compartment (i.e., a position close to the center of the left-right direction inside the clamping compartment). By setting the elastic aligning plate 326, during the insertion of the clamping clamp 13, the elastic aligning plate 326 will align the closed tail of the clamping clamp 13 to a central position inside the metal clamping chamber, so that the head of the pusher plate can effectively act on the closed tail of the clamping clamp 13, stabilize the clamping, and avoid clamping failure.

[0107] See Figure 5 , Figure 6 and Figure 7 Furthermore, during clamping, the head of the pusher clip located at the distal end of the pusher clip abuts against the closed tail of the clamping clamp 13 to be inserted. The pusher clip head includes a V-shaped pusher 42, and during clamping, the opening of the V-shaped pusher 42 abuts against the closed tail of the clamping clamp 13 to be inserted. The V-shaped pusher 42 includes a first support and a second support. The first end of the first support intersects with the first end of the second support, and the second ends of the first and second supports form the two ends of the opening of the V-shaped pusher 42. The bottom angle of the V-shaped pusher 42 formed by the intersection of the first and second supports is located in the middle of the clamping chamber. The length of the first support is greater than the length of the second support. Before clamping, the first support is close to the aligning side wall. Thus, during the clamping process, the pusher plate advances towards the far end of the clamping chamber. The first plate first contacts the closed tail of the clamp to be inserted. As the pusher plate continues to advance, the closed tail of the clamp to be inserted 13 is aligned along the first plate towards the interior of the metal clamping chamber until the opening of the V-shaped pusher plate 42 completely abuts against the closed tail of the clamp to be inserted 13. The V-shaped pusher plate provided in this embodiment can not only push the clamp to be inserted, but also align the closed tail of the clamp to be inserted to a central position inside the metal clamping chamber, so that the V-shaped pusher plate can effectively act on the closed tail of the clamp to be inserted, ensuring stable clamping.

[0108] Of course, when both the elastic aligning plate 326 and the aforementioned V-shaped pusher 42 are present, the starting pushing position of the V-shaped pusher 42 on the clamp ligation clip to be inserted corresponds to the proximal end of the elastic aligning plate 326, and the two work together to guide the clamp ligation clip 13 to be inserted. However, the present invention is not limited to this, and other embodiments may use either the elastic aligning plate 326 or the aforementioned V-shaped pusher 42.

[0109] Example 2

[0110] The main difference between this embodiment and Embodiment 1 is that, Figure 16 As shown, two first elastic clips are provided on the bottom plate of the metal clamping section. The plastic clamping section 31 is located near the nearest first elastic clip on the metal clamping section 32, and the far end of the plastic clamping section 31 is the far end of the clamping section. This design ensures that the clamping section, after the installation of matching parts, can smoothly pass through existing piercing tools, enabling the combined use of the plastic and metal clamping sections while further reducing the length of the metal clamping section processed in sheet metal work.

[0111] The remaining similarities to those in Example 1 will not be repeated here.

[0112] Example 3

[0113] The main difference between this embodiment and Embodiment 1 is that, Figure 17As shown, a first elastic clip is provided on the bottom plate of the metal clamping section. The plastic clamping section 31 is located near the first elastic clip on the metal clamping section 32, and the distal end of the plastic clamping section 31 is the distal end of the clamping section. This design ensures that the clamping section, after the installation of matching parts, can smoothly pass through existing piercing tools, enabling the combined use of the plastic and metal clamping sections while further reducing the length of the metal clamping section processed in sheet metal work.

[0114] The remaining similarities to those in Example 1 will not be repeated here.

[0115] Example 4

[0116] The main difference between this embodiment and Embodiment 1 is that the snap-fit ​​connection between the proximal end of the metal clip section and the distal end of the plastic clip section is replaced with an adhesive connection between the proximal end of the metal clip section and the distal end of the plastic clip section.

[0117] Specifically, the proximal end of the bottom plate of the metal clamping section is adhesively connected to the bottom plate of the placement groove, the proximal end of the left side wall of the metal clamping section is adhesively connected to the left side wall of the placement groove, and the proximal end of the right side wall of the metal clamping section is adhesively connected to the right side wall of the placement groove. This achieves a stable connection between the plastic clamping section and the metal clamping section.

[0118] It is conceivable that a stable connection between the plastic and metal clamping parts can be achieved simply by gluing the near end of the metal clamping part's bottom plate to the bottom plate of the placement groove; or by gluing any two of the metal clamping part's bottom plate, left side wall, and right side wall to the placement groove, a stable connection between the plastic and metal clamping parts can also be achieved.

[0119] The remaining similarities to those in Example 1 will not be repeated here.

[0120] Example 5

[0121] The main difference between this embodiment and Embodiment 1 is that a boss, called an insertion boss 322, is provided in the middle of the left-right direction of the bottom plate of the metal clamping compartment along the clamping direction. The insertion end of the insertion boss 322 is located near the end of the bottom plate of the metal clamping compartment and far from the buckle hole 321. By providing an insertion boss that starts near the end of the bottom plate and ends far from the end of the bottom plate of the metal clamping compartment along the clamping direction in the middle of the left-right direction, it is ensured that the boss can support the closed tail of all the ligation clips inside the metal clamping compartment, which is conducive to pushing the clip and making the clamping more stable.

[0122] The remaining similarities to those in Example 1 will not be repeated here.

[0123] Example 6

[0124] The main difference between this embodiment and Embodiment 1 is that two protrusions are provided in the middle of the bottom plate of the metal clamp compartment along the clamping direction in the left-right direction. One of the protrusions is the clamping protrusion 322 already discussed above, and the other protrusion is the second clamping protrusion. The clamping end of the second clamping protrusion is located near the end of the bottom plate of the metal clamp compartment and far from the buckle hole 321, while the clamping exit end of the second clamping protrusion is near the clamping protrusion 322. Thus, the function of the second clamping protrusion is to improve the stability of the ligation clamp on the near side of the metal clamp compartment as it is pushed to the far side.

[0125] Furthermore, the second clamping boss is a metal strip welded to the bottom plate of the metal clamping compartment. This facilitates machining.

[0126] The remaining similarities to those in Example 1 will not be repeated here.
