Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and more particularly, to a ligating clip cartridge. Background Art
[0002] In minimally invasive surgery, a ligating clip is often fixed to tissue or a blood vessel by a clip applicator to achieve hemostasis and ligation closure. The ligating clip in the prior art includes a pair of curved legs, the two legs are connected at the proximal end, and the distal end includes a latch member. The clip applicator is used to close the ligating clip located on the tissue to be ligated, and the ligating clip can be locked in the closed state after being closed. During the operation, the jaw assembly of the clip applicator is actuated to compress the legs of the ligating clip, which causes the legs to pivot inwardly around the proximal connection of the two legs, thereby closing the ligating clip and maintaining the closed state through the latch member.
[0003] In order to facilitate the clip applicator to pick up the ligating clip, the existing ligating clip can be placed in a dedicated ligating clip cartridge. A plurality of ligating clips are arranged at intervals in the base of the ligating clip cartridge, and the proximal connection of the ligating clip is supported by a support member in the cartridge. When in use, the clip applicator can directly pick up the ligating clip from the cartridge. Since the sizes of the jaw assemblies of different clip applicators are not exactly the same, and the doctor cannot accurately control the force when picking up the clip from the cartridge with the clip applicator, it is easy to cause the proximal connection of the ligating clip to be subjected to too much force, resulting in the breakage of the ligating clip at the proximal connection and affecting the use of the ligating clip. Summary of the Invention
[0004] To solve the above technical problems, the present invention provides a ligating clip cartridge, which enables the ligating clip to move within the cartridge when subjected to a large external force, thereby avoiding accidental breakage of the ligating clip.
[0005] The present application provides the following technical solution: A ligating clip cartridge, the ligating clip cartridge comprising: a ligating clip; a base and a plurality of spaced-apart partition members, the plurality of partition members being connected to the base; a support member, the support member being located between two adjacent partition members and connected to the partition member and / or the base, the support member including a suspension portion for supporting the ligating clip, and in response to an external force being applied to the suspension portion, the suspension portion moves relative to the partition member and / or the base, so that the ligating clip supported on the suspension portion moves relative to the partition member and / or the base.
[0006] Compared with the prior art, the beneficial effect of the present invention is that by setting the suspension portion of the support member in the ligating clip cartridge to be movable, when the clip applicator picks up the ligating clip supported on the suspension portion, the ligating clip can move together with the suspension portion, thereby avoiding the part of the ligating clip in contact with the suspension portion from continuously being subjected to a large force and avoiding breakage of the ligating clip.

The connection end is connected to the partition member and / or the base, and the ligating clip is supported at the free end of the suspension portion. In response to an external force applied to the suspension portion, the free end of the suspension portion rotates, causing the suspension portion to move relative to the partition member and / or the base.
[0008] In some embodiments, the support member further includes a support portion. The support portion is connected to the base and / or the partition member, and the connection end of the suspension portion is connected to the support portion. In response to an external force applied to the suspension portion, the free end of the suspension portion rotates relative to the connection end, causing the suspension portion to move relative to the partition member and / or the base.
[0009] In some embodiments, the partition member includes a partition body and a partition thickening portion provided on the partition body. The support member is disposed between the partition thickening portions of two adjacent partition members.
[0010] In some embodiments, the ligating clip cartridge includes an elastic member. One end of the elastic member is connected to the base and / or the partition member, and the other end of the elastic member is connected to the suspension portion. In response to an external force applied to the suspension portion, the elastic member is compressed and deformed, causing the suspension portion to move relative to the partition member and / or the base.
[0011] In some embodiments, there is a gap between the suspension portion and the partition member.
[0012] In some embodiments, the suspension portion includes a support surface for supporting the ligating clip, and the support surface includes at least an arc surface.
[0013] In some embodiments, a plurality of the partition members are spaced apart in a first direction, and the planes where the plurality of partition members are located are parallel to each other. The first direction intersects the plane where the partition member is located.
[0014] In some embodiments, the ligating clip includes a first clip leg and a second clip leg. The first clip leg and the second clip leg are connected by a connecting portion, and the suspension portion supports the connecting portion.
[0015] In some embodiments, the connecting portion further includes a weakening portion for reducing the strength of the connecting portion. The weakening portion is a thickness reduction region or a hollowed-out region.

[0039] The following will Figures 1 - 15 describe in detail the ligating clip cartridge 10 of the embodiment of the present invention.
[0040] Referring to Figures 1 - 12 As shown, the ligating clip cartridge 10 of the embodiment of the present invention includes a base 1, a separator 2 and a support member 3.
[0041] Among them, there are a plurality of separators 2, and the plurality of separators 2 are all connected to the base 1, and adjacent separators 2 are arranged at intervals. An access space is formed between two adjacent separators 2. The support member 3 is disposed in the access space formed by two adjacent separators 2, and the support member 3 is connected to the separator 2 and / or the base 1. The ligating clip 20 is supported on the support member 3. When the ligating clip 20 needs to be used, the ligating clip 20 is clamped out from the access space by a clip applicator 30. By providing a plurality of separators 2, a plurality of ligating clips 20 can be placed on the support members 3 in different access spaces, so that a plurality of ligating clips 20 can be stored in the same cartridge, which is convenient for the storage of the ligating clips 20.
[0042] Referring to Figure 13As shown, the ligating clip 20 includes a first leg 201 and a second leg 202. A connection portion 206 is formed at the connection of the first leg 201 and the second leg 202, and the support member 3 supports the connection portion 206. The first leg 201 includes an engaging portion 205 and a first protrusion 203, and the second leg 202 includes two second protrusions 204. The size of the engaging portion 205 is slightly larger than the distance between the two second protrusions 204, and the two second protrusions 204 have a certain elasticity and can be deformed. Thus, in response to the closing of the ligating clip 20, the first leg 201 and the second leg 202 pivot relative to each other around the connection portion 206, causing the engaging portion 205 to move between the two second protrusions 204. The two second protrusions 204 are deformed under the action of the engaging portion 205 to engage the engaging portion 205 between the two second protrusions 204. At this time, the clip is in a closed state, the first leg 201 and the second leg 202 are fully clamped, and the blood vessel or tissue placed between the first leg 201 and the second leg 202 can be effectively clamped and hemostatic.
[0043] Referring to Figure 13 As shown, a weakening portion 207 is further provided on the connection portion 206 of the ligating clip 20. The weakening portion 207 can weaken the strength of the connection portion 206, so that when the first leg 201 and the second leg 202 of the ligating clip 20 rotate and close, the connection portion 206 is easily deformed, thereby making the ligating clip 20 close more easily and be applied to a blood vessel or tissue. Optionally, the weakening portion 207 can be a thickness-reduced area or a hollowed-out area.
[0044] Figure 14 As shown, a common clip applicator 30 in the art is shown. The clip applicator 30 includes a jaw assembly 301 at the distal end, an operating assembly 303 at the proximal end, and a shaft assembly 302 between the jaw assembly 301 and the operating assembly 303. The operating assembly 303 includes a main body 3031 and a wrench 3032 movably mounted on the main body 3031. The clip applicator 30 further includes a transmission mechanism. A part of the transmission mechanism is located inside the main body 3031 and is in transmission connection with the wrench 3032, and a part of the transmission mechanism is located inside the shaft assembly 302 and is in transmission connection with the jaw assembly 301. When the wrench 3032 moves, it can drive the transmission mechanism to move, so that the transmission mechanism can drive the jaw assembly 301 to close or open. As Figure 15 As shown, the jaw assembly 301 of the clip applicator 30 includes a first jaw 3013 and a second jaw 3014. The proximal ends of the first jaw 3013 and the second jaw 3014 are hinged. In response to the movement of the wrench 3032, the transmission mechanism can drive the first jaw 3013 and the second jaw 3014 to approach or separate from each other, so that the jaw assembly 301 closes or opens. When clamping the ligating clip 20, the ligating clip 20 is clamped by the first jaw 3013 and the second jaw 3014 of the jaw assembly 301.
[0045] Figure 14 A knob 304 is also shown between the shaft assembly 302 and the operating assembly 303. The knob 304 is fixed to the shaft assembly 302. When the knob 304 is rotated, the angles of the shaft assembly 302 and the jaw assembly 301 relative to the operating assembly 303 can be changed, facilitating the doctor to adjust the jaw assembly 301 to an appropriate angle for the next operation.
[0046] When the ligating clip 20 is located in the jaw assembly of the clip applicator 30, the protrusion of the ligating clip 20 is located in the groove of the jaw, facilitating the fixation of the ligating clip 20 relative to the jaw. Specifically combined with Figure 6 、 Figures 13 - 15 shown, taking Figure 15 the direction as a reference, the direction shown by F5 is downward. When it is necessary to pick up the clip from the clip cartridge, the jaw assembly 301 moves downward and extends into the ligating clip cartridge 10 until the first groove 3011 on the first jaw arm 3013 of the jaw assembly 301 engages with the first protrusion 203 on the ligating clip 20, and the second groove 3012 on the second jaw arm 3014 of the jaw assembly 301 engages with the second protrusion 204 on the ligating clip 20. At this time, the ligating clip 20 can be taken out from the ligating clip cartridge 10 and the next surgical action can be performed to apply the ligating clip 20 on the blood vessel or tissue. Specifically, in response to closing the wrench 3032, the jaw assembly 301 closes, causing the first leg 201 and the second leg 202 of the ligating clip 20 to pivot inwardly around the connecting portion 206 and finally reach the closed state, thereby fixing the ligating clip 20 on the blood vessel or tissue.
[0047] When the jaw assembly 301 moves downward to the bottom of the ligating clip cartridge 10, the jaw assembly 301 abuts against the base 1 of the cartridge. Since the jaw lengths of the clip applicators 30 from different manufacturers are inconsistent, especially the distance from the groove of the jaw assembly 301 to the farthest end of the jaw assembly 301 ( Figure 15 H2 in Figure 6 、 Figures 13 - 15As shown, when the jaw assembly 301 moves downward, since it is difficult for the doctor to accurately control the downward movement stroke and the magnitude of the force, after the protrusion on the jaw groove is engaged with the ligation clip 20, if the jaw assembly 301 continues to move downward, if the support member 3 is fixed relative to the partition member 2 and / or the base 1, it will cause the connecting portion 206 of the ligation clip 20 to abut against the support member 3 and continuously receive a large force, which is likely to break.
[0048] To solve the above technical problems, the present application proposes a ligation clip cartridge 10. The support member 3 of the ligation clip cartridge 10 includes a suspension portion 32 for supporting the ligation clip 20. In response to an external force applied to the suspension portion 32, the suspension portion 32 can move relative to the partition member 2 and / or the base 1. It should be understood that the external force applied here can be directly applied to the suspension portion 32. Since the ligation clip is supported on the suspension portion 32, it can also be applied to the suspension portion 32 by applying an external force to the ligation clip 20. Therefore, when a large external force is applied to the ligation clip 20, the suspension portion 32 can move, so that the ligation clip 20 can also move adaptively, thereby avoiding the connecting portion 206 of the ligation clip from breaking due to continuous force. Specifically, taking Figure 6 the shown angle as an example, in combination with Figures 13 - 15 , when the clip applicator 30 extends into the cartridge to pick up the clip, since the user cannot accurately control the movement or the magnitude of the applied force, a large force may be applied to the connecting portion 206 of the ligation clip 20, causing the suspension portion 32 of the support member 3 to also receive a large force. At this time, the suspension portion 32 can move relative to the partition member 2 and / or the base 1, so that the ligation clip 20 can move together with the suspension portion 32, thereby avoiding the clip applicator 30 from continuously applying force to the portion where the ligation clip 20 abuts against the support member 3 (i.e., the connecting portion 206) and causing the ligation clip 20 to break. It can be understood that during the downward movement of the suspension portion 32, the suspension portion 32 can also move horizontally to adapt to different application force angles of the operator. After the external force acting on the suspension portion 32 is withdrawn, the suspension portion 32 can return to its free state, that is, the position when not affected by the external force.
[0049] According to the ligation clip cartridge 10 of the embodiment of the present invention, the suspension portion 32 of the support member 3 is movable relative to the base 1 and / or the partition member 2 when subjected to an external force. Therefore, when a large external force is applied to the ligation clip 20, it can move together with the suspension portion 32, so that the ligation clip 20 has a certain moving space in the cartridge, avoiding the breakage of the portion where the ligation clip 20 abuts against the support member 3 (i.e., the connecting portion 206). The ligation clip cartridge 10 according to the embodiment of the present invention has a simple structure, can reduce the risk of ligation clip 20 breakage during the operation, does not require a large modification to the current base 1 structure, and is applicable to most clip applicators 30 on the market, which is beneficial to cost savings.
[0050] It is understandable that the external force applied to the suspension portion 32 can be applied by the clamping pliers 30, or can be applied by a human hand or other tools.
[0051] In some embodiments, referring to Figures 1 - 4 , Figure 9 As shown, the separator 2 is configured as a flat plate structure, which can be referred to as a separator plate. The base 1 has a fixed surface, and the plane of the separator plate is perpendicular to the fixed surface of the base 1, which is beneficial to the taking and placing operations of the ligating clip 20 in the access space. It should be noted that the plane of the separator plate is the plane facing the adjacent separator plate. Specifically, a plurality of separators 2 are arranged at intervals in the first direction, and the planes where the plurality of separators 2 are located are parallel to each other, and the first direction intersects the plane where the separator 2 is located. Optionally, the first direction is perpendicular to the plane where the separator 2 is located. In this embodiment, the first direction is the direction shown by F1-F2.
[0052] In some embodiments, referring to Figure 1 As shown, the base 1 may include a base body 11 and a baffle 12. The baffle 12 is located on the side surface of the base body 11, and the upper surface of the base body 11 is the fixed surface connected to the separator 2. The baffle 12 can be configured as a surrounding structure to comprehensively shield the outer periphery of the base body 11, that is, the baffle 12 is provided on the F1, F2, F3, and F4 sides of the base body 11. The baffle 12 can also be only provided on the two sides of the base 1 perpendicular to the plane where the separator is located, that is, the baffle 12 is provided on the F3 and F4 sides of the base body 11, and the baffle is not provided on the F1 and F2 sides. The baffle 12 has a certain shielding effect to prevent external dust, sundries, etc. from entering the access space between the two separators 2. In some embodiments, the ligating clip cartridge 10 further includes a lid (not shown), and the baffle 12 can provide a positioning structure for the lid.
[0053] In some embodiments of the present invention, there is a gap between the suspension portion 32 and the separator 2 to allow the suspension portion 32 to move relative to the separator 2 when the suspension portion 32 is subjected to an external force, and the suspension portion 32 will not be stuck due to friction with the separator 2 during movement. Referring to Figures 7 - 8 As shown, there are gaps between the F1 side and the F2 side of the suspension portion 32 and the separator 2, and the unilateral gap between the suspension portion 32 and the separator 2 is H1. Optionally, H1 < 1 mm. For example, H1 can be 0.1 mm, 0.2 mm, 0.3 mm, etc. Of course, H1 can also be other values less than 1 mm, which will not be listed one by one here.
[0054] In some embodiments of the present invention, the support member 3 further includes a support portion 31, and the support portion 31 is connected to the base 1 and / or the partition member 2. That is to say, in some embodiments, the support portion 31 may be directly connected only to the base 1; in some other embodiments, the support portion 31 may be directly connected only to the partition member 2; in still other embodiments, the support portion 31 may be connected to both the base 1 and the partition member 2. The suspension portion 32 is connected to the support portion 31, that is, the suspension portion 32 is supported by the support portion 31 within the access space between the two partition members 2.
[0055] In some embodiments of the present invention, referring to Figures 3 - 6 、 Figures 9 - 12 as shown, the partition member 2 includes a partition body 21 and a partition thickening portion 22, the partition thickening portion 22 is provided on the partition body 21, and the support member 3 is located between the partition thickening portions 22 of two adjacent partition members 2.
[0056] Referring to Figure 9 as shown, in the F3 - F4 direction, the partition thickening portion 22 is located at the middle position of the partition body 21. In this way, there is a relatively large space on both the F3 side and the F4 side of the partition thickening portion 22, which is convenient for the two clamping arms of the clamping pliers to extend into the clip box to pick up the ligating clip 20. At the same time, the distance between the two partition thickening portions 22 of two adjacent partition members 2 is relatively small, and the ligating clip 20 can be placed more stably on the support member 3 between the two partition thickening portions 22 without easily shaking.
[0057] In some embodiments of the present invention, the support portion 31 is fixed to the partition thickening portion 22, and there is a gap between the suspension portion 32 and the partition thickening portion 22. Referring to Figures 4 - 5 、 Figures 7 - 8 as shown, the support portion 31 is fixed to the partition thickening portion 22, and there are gaps between the F1 side and the F2 side of the suspension portion 32 and the partition thickening portion 22. The unilateral gap between the suspension portion 32 and the partition thickening portion 22 is H1. Optionally, H1 < 1 mm. For example, H1 can be 0.1 mm, 0.2 mm, 0.3 mm, etc.
[0058] In some embodiments of the present invention, referring to Figure 3 as shown, a notch groove 221 is provided on the partition thickening portion 22, and the notch groove 221 can further increase the gap between the suspension portion 32 and the partition thickening portion 22.
[0059] In some embodiments of the present invention, referring to Figures 4 - 5 、 Figure 9 、 Figures 11 - 12As shown, the suspension part 32 has a support surface for supporting the ligating clip 20, and the support surface at least includes an arc surface 321. Optionally, the support surface can be a combined surface of the arc surface 321 and a flat surface. The provision of the arc surface 321 can reduce the contact stress between the ligating clip 20 and the support surface, and further reduce the risk of fracture of the ligating clip 20.
[0060] In some embodiments of the present invention, referring to Figures 1 - 2 , Figure 7 As shown, there is one support member 3 in the access space between two adjacent partition members 2, and the ligating clip 20 is supported by the support member 3. Therefore, there is only one ligating clip 20 between two adjacent partition members 2, which can avoid the problem that when multiple ligating clips 20 are stored in one access space, the multiple ligating clips 20 interfere with each other and it is impossible to quickly pick up the clips.
[0061] In some embodiments of the present invention, in combination with Figure 4 , Figure 6 , Figure 9 , Figures 14 - 15 , there is also a limiting boss 13 provided between two adjacent partition members 2. The limiting boss 13 is arranged on the base 1 and is used to limit the clamping arms of the clip applicator 30. When the clamping arms move downward to the bottom of the ligating clip cassette 10, the clamping arms abut against the limiting boss 13. The height of the limiting boss 13 is less than the height of the support member 3. When the user uses the clip applicator to pick up the ligating clip 20, the user can clearly sense that the clamping arms of the clip applicator have abutted against the limiting boss 13, so as to provide clear feedback or prompt to the user.
[0062] In some embodiments of the present invention, referring to Figure 6 , Figure 9 and Figure 11 As shown, the suspension part 32 is a cantilever structure. One end of the suspension part 32 is a connection end 323, and the other end of the suspension part 32 is a free end 322. The connection end 323 is connected to the partition member 2 and / or the base 1, and the ligating clip 20 is supported on the free end 322 of the suspension part 32. In response to an external force being applied to the ligating clip 20, that is, an external force is applied to the suspension part 32, the free end 322 of the suspension part 32 can rotate relative to the connection end 323, so that the suspension part 32 moves relative to the partition member 2 and / or the base. Therefore, the ligating clip 20 can move with the suspension part 32, avoiding the fracture of the connection part 206 of the ligating clip 20 due to continuous stress.
[0063] In some embodiments of the present invention, referring to Figure 12As shown, the ligating clip cartridge 10 includes an elastic member 33. One end of the elastic member 33 is connected to the base 1 and / or the partition member 2, and the other end of the elastic member 33 is connected to the suspension portion 32. The elastic member 33 is configured to be compressively deformed when an external force is applied to the suspension portion 32, so that the suspension portion 32 moves. Specifically, the ligating clip 20 is placed on the suspension portion 32. When an external force is applied to the ligating clip 20, the suspension portion 32 is subjected to the external force and moves, the elastic member 33 is compressively deformed, and the ligating clip 20 will move along with the suspension portion 32, preventing the connecting portion 206 of the ligating clip 20 from breaking due to continuous force. Optionally, the elastic member 33 is a spring.
[0064] The following refers to Figures 4 - 8 describe the ligating clip cartridge 10 according to the first specific example of the present invention.
[0065] The ligating clip cartridge 10 includes a base 1, a support member 3, and a plurality of partition members 2. The plurality of partition members 2 are all connected to the base 1, and the plurality of partition members 2 are arranged at intervals and parallel to each other in the F1-F2 direction. An access space is formed between adjacent two partition members 2, and each access space is provided with a support member 3. The partition member 2 includes a partition body 21 and a partition thickening portion 22. The support member 3 is located between the partition thickening portions 22 of adjacent two partition members 2.
[0066] The support member 3 includes a suspension portion 32. The suspension portion 32 is a cantilever structure, including a free end 322 and a connection end 323. The connection end 323 is connected to the partition member 2 or the base 1, and the free end 322 supports the ligating clip 20. Specifically, the support member 3 further includes a support portion 31. The connection end 323 of the suspension portion 32 is connected to the support portion 31, and the support portion 31 is connected to the partition thickening portion 22 of the partition member 2. As Figure 5 、 Figure 6 and Figure 8 shown, the part of the support member 3 below the dotted line L1 is the support portion 31, and the part of the support member 3 above the dotted line L1 is the suspension portion 32. There is a gap between the suspension portion 32 and the partition thickening portion 22. When a downward pressure is applied to the ligating clip 20, that is, when the suspension portion 32 is stressed, the free end 322 of the suspension portion 32 rotates and thus undergoes slight deformation. Therefore, the ligating clip 20 will also move accordingly, preventing the connecting portion 206 of the ligating clip 20 from breaking due to continuous force. In this embodiment, when the suspension portion 32 rotates under the action of an external force, there is no relatively fixed pivot point.
[0067] In this embodiment, the suspension portion 32 and the support portion 31 can be integrally formed, and a plastic material with a certain rigidity is used. The free end 322 of the suspension portion 32 can not only stably support the ligating clip 20, but also rotate under the action of an external force to generate a certain deformation.
[0068] The following refers to Figures 9 - 10 describe the ligating clip cartridge 10 according to the second specific example of the present invention.
[0069] This embodiment is basically the same as the clamping box structure of the first embodiment, except for the specific structure of the support member 3. The support member 3 includes a support portion 31 and a suspension portion 32. The suspension portion 32 is also a cantilever structure. The free end 322 of the suspension portion is used to support the ligating clip 20. The connecting end 323 of the suspension portion is connected to the support portion 31. The free end 322 of the suspension portion 32 can rotate relative to the support portion 31 around the connecting end 323. As Figure 10 shown, the part of the support member 3 below the dotted line L2 is the support portion 31, and the part of the support member 3 above the dotted line L2 is the suspension portion 32. The ligating clip 20 is placed on the suspension portion 32. When the ligating clip 20 is subjected to a downward pressure, that is, the suspension portion 32 is stressed, the suspension portion 32 can cause the suspension end 322 to rotate around the connecting end 323 when subjected to an external force, so that the ligating clip 20 can move accordingly, avoiding the fracture of the connecting portion 206 of the ligating clip 20 due to continuous stress.
[0070] Next, refer to Figure 11 to describe the ligating clip cassette 10 according to the third specific example of the present invention.
[0071] This embodiment is basically the same as the clamping box structure of the first embodiment, except for the specific structure of the support member 3. The support member 3 includes a suspension portion 32. The suspension portion 32 includes a free end 322 and a connecting end 323. The connecting end 323 is directly connected to the base 1. There is a gap between the suspension portion 32 and the partition thickening portion 22. The ligating clip 20 is placed on the suspension portion 32. When the ligating clip 20 is subjected to a downward pressure, that is, the suspension portion 32 is stressed, the free end 322 of the suspension portion 32 rotates around the connecting end 323, so as to generate a relative movement relative to the separator 2, and the ligating clip 20 will also move accordingly, avoiding the fracture of the connecting portion 206 of the ligating clip 20 due to excessive stress.
[0072] Next, refer to Figure 12 to describe the ligating clip cassette 10 according to the fourth specific example of the present invention.
[0073] This embodiment is basically the same as the clamping box structure of the first embodiment, except for the specific structure of the support member 3 and the connection method with the clamping box. The clamping box includes an elastic member 33. The support member 3 includes a suspension portion 32. The suspension portion 32 is connected to the base 1 through the elastic member 33. Preferably, the elastic member 33 is a spring. One end of the spring is connected to the base 1, and the other end of the spring is connected to the suspension portion 32. There is a gap between the suspension portion 32 and the separator 2. When the ligating clip 20 is subjected to a downward pressure, the suspension portion 32 moves downward under the external force, and the spring is compressed and deformed. The ligating clip 20 will follow the movement of the suspension portion 32, avoiding the fracture of the connecting portion 206 of the ligating clip 20 due to excessive stress.
[0074] In summary, in the present invention, the suspension portion that supports the ligating clip in the ligating clip cartridge is set to be movable relative to the base and / or the partition member, so that when the clip applicator picks up the ligating clip supported on the suspension portion, the ligating clip can move together with the suspension portion, thereby preventing the portion of the ligating clip in contact with the suspension portion from continuously being subjected to a large force and reducing the risk of breakage of the ligating clip.
