To clearly illustrate the technical problem that the present invention actually solves, it is explained below by an exemplary ligating clip and a clip magazine assembly of an exemplary clip applier. It should be understood, however, that the clip cartridge apparatus provided by the present invention should not be limited by the exemplary ligation clips and clip cartridge apparatus of the exemplary clip applier set forth herein. Rather, these examples are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

As shown in fig. 1, the conventional ligating clip includes a V-shaped ligating clip body 1,V, and the ligating clip body 1 generally includes a first clip arm 11 and a second clip arm 12 connected to each other, one end of each clip arm is connected to form a closed tail of the ligating clip, the other end of each clip arm is a free end, and the free ends of the two clip arms are far away from each other to form a V shape. Preferably, the V-shaped ligating clip body 1 is integrally formed by a first clip arm 11 and a second clip arm 12. The free end of the first arm 11 is provided with a locking hook 111 bending inwards, and the free end of the second arm 12 is provided with a hook slot 121 adapted to the locking hook 111. In order to facilitate the clipping of the ligating clip by the jaw 9 of the clip applier, a first clipping column 21 is arranged at a position (i.e. a position close to the free end) of the first clipping arm 11 close to the locking hook 111, and the height direction of the first clipping column 21 is perpendicular to the side plane of the V-shaped ligating clip body 1, and two first clipping columns 21 are symmetrically arranged at two sides of the first clipping arm 11. In the embodiment shown in fig. 1, the two first clamping posts 21 are connected, but they may be disconnected. A second clamping column 22 is disposed at a position (i.e. a position close to the free end) of the second clamping arm 12 close to the hook slot 121, the height direction of the second clamping column 22 is perpendicular to the side plane of the V-shaped ligating clip body 1, two second clamping columns 22 are symmetrically disposed at two sides of the second clamping arm 12, in this embodiment, the two second clamping columns 22 are disconnected, and the hook slot 121 is disposed therebetween. Further, the first clamping arm 11 is an arc shape protruding towards the outside of the V-shaped ligating clip body 1, and the second clamping arm 12 is an arc shape protruding towards the inside of the V-shaped ligating clip body.

As shown in fig. 2, 4 and 7, the clip magazine assembly of the hair clip applier includes a clip magazine 3 that houses a plurality of ligation clips and a pusher jaw 4 that pushes the ligation clips. The plurality of ligation clips comprise a ligation clip 13 to be inserted (a ligation clip to be inserted into a jaw) which is positioned at the most distal end of the clip bin and ligation clips which are stored in a row at the near side of the ligation clip 13 to be inserted; openings of the ligation clamps are horizontally placed on a bottom plate 31 of the clamping bin in sequence towards the clamp feeding direction, a first clamping arm 11 of each ligation clamp is attached to a first side wall of the clamping bin 3, a second clamping arm 12 of each ligation clamp is attached to a second side wall of the clamping bin 3, and a plurality of first elastic clamping positions 311 which are tilted upwards along the clamp feeding direction are arranged on the bottom plate 31 of the clamping bin at equal intervals; push away clamping piece 4 including what connect gradually push away the clamping piece body 41 with push away the clamping piece head, push away the clamping piece head and push away clamping piece body 41 to a lateral buckling relatively, push away clamping piece body 41 and cover in the top of the ligature clamp except waiting to go into the pincers ligature clamp, push away the clamping piece head and stretch into the clamp storehouse 3 inside and be close to and wait to go into the setting of pincers ligature clamp 13, push away clamping piece body 41 equidistant be provided with a plurality of edges and send the second elasticity screens 411 that press from both sides the direction and perk downwards.

Before the continuous hair clip applier is used for sending clips, the ligation clips 13 to be inserted are closer to the far end of the clip bin 3 relative to the first elastic clamping positions 311 at the far end, the clamping columns of the ligation clips except the ligation clips 13 to be inserted are positioned between the two adjacent first elastic clamping positions 311, and the second elastic clamping positions 411 are positioned between the clamping columns of the adjacent ligation clips except the ligation clips 13 to be inserted. When the hair clip applier delivers clips, the push clip 4 advances towards the far end of the clip bin, the tilting part of the second elastic clip 411 gradually butts against the first clamping column 21 and/or the second clamping column 22 of all ligation clips except the ligation clip 13 to be inserted, and meanwhile, the head part of the push clip butts against the tail part of the ligation clip 13 to be inserted. As the clip pushing piece 4 continues to advance towards the distal end of the clip bin 3, all the ligation clips are pushed to advance towards the distal end of the clip bin 3 until the ligation clips 13 to be inserted enter the jaws 9, the clip pushing piece 4 stops advancing towards the distal end of the clip bin 3, and in the process, all the ligation clips except the ligation clips 13 to be inserted can cross over the distally adjacent first elastic clamping positions 311. Then the pushing and clamping piece 4 advances towards the proximal end of the clamping bin 3, the head of the pushing and clamping piece and the second elastic clamping piece 411 can drive all the ligation clamps except the to-be-clamped ligation clamp 13 to advance towards the proximal end of the clamping bin 3, when all the ligation clamps except the to-be-clamped ligation clamp 13 are in contact with the first elastic clamping position 311, the first elastic clamping position 311 can prevent all the ligation clamps except the to-be-clamped ligation clamp 13 from continuing to advance towards the proximal end of the clamping bin 3, and because the head of the pushing and clamping piece and the second elastic piece 411 have elasticity, the head of the pushing and clamping piece and the second elastic piece 411 can cross over the adjacent ligation clamps on the proximal side of the pushing and clamping piece, and then the pushing and clamping piece 4 stops advancing towards the proximal end of the clamping bin 3. The clip pushing piece 4 is thus reciprocated to sequentially feed the ligation clips to the jaw 9.

The applicant finds that if the repeating clip applier is designed in the structure, the mechanism of the repeating clip applier is jammed and the clip sending fails in the actual use process, and the following factors mainly exist: 1. because the existence of the first centre gripping post of ligature clamp and second centre gripping post, the closed afterbody of the ligature clamp of storage in pressing from both sides the storehouse is in unsettled state, and the closed afterbody of the ligature clamp of send double-layered in-process can the luffing motion, is unfavorable for the clamping piece propelling movement to press from both sides for send and press from both sides unstably, thereby appear sending to press from both sides the dead situation of card. 2. In the process of clamping and conveying the ligation clamp to the jaw, the two clamping arms of the ligation clamp are in an arc shape protruding towards the same direction, so that the closed tail of the ligation clamp stored in the clamping bin is usually deviated to one side wall (the second side wall in the embodiment) of the clamping bin, the head of the clamping piece is not pushed to abut against the closed tail of the ligation clamp to be clamped, the clamp conveying is completed, and the clamp conveying fails; 3. when the ligation clamp is fed into the clamp, the ligation clamp is conveyed to the jaw, and the ligation clamp swings upwards due to the allowance space between the ligation clamp and the top plate of the clamp bin, so that the ligation clamp is not conveyed to the jaw, and the conveying clamp is unstable. The clamp can be more stable compared with the prior art by solving any technical problem.

Therefore, the invention provides a stable feeding and clamping bin device. For a better understanding of the present invention, reference will now be made in detail to the present embodiments of the invention, which are illustrated in the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.

Example 1

As shown in fig. 2-4, the present embodiment provides a clip magazine device comprising a clip magazine 3 housing a plurality of ligation clips.

As shown in fig. 2 and 4, the design of the ligation clip is the same as that described above and will not be described again. The openings of the ligation clamps are sequentially horizontally placed on the bottom plate 31 of the clamping bin towards the clamp feeding direction, and two ends of the opening of the V-shaped ligation clamp body 1 are respectively attached to two side walls of the clamping bin 3. On the basis of the structure described above, the clamping chamber 3 is further provided with at least one boss in the middle of the clamping chamber bottom plate 31 in the left-right direction and in the feeding direction (that is, the left and right positions of the boss are in the middle of the clamping chamber bottom plate 31), and when the ligation clip is fed along the boss, the top of the boss gradually supports the closed tail of the ligation clip, so that the closed tail of the ligation clip is finally parallel to the plane of the bottom plate 31 of the clamping chamber. So, the boss props up the closed afterbody of ligature clamp, reduces and send the luffing motion of clamping closed afterbody in the clamp process, does benefit to the clamping piece propelling movement and presss from both sides, makes to send to press from both sides stably, reduces and send the clamp dead situation of card.

As shown in fig. 2 to 6, in the present embodiment, at least one of the bosses is a clamp-in boss 312 (a boss entering a jaw), a clamp-in end of the clamp-in boss 312 is located on the cartridge bottom plate 31, and a clamp-out end of the clamp-in boss 312 is located at a distal end of the cartridge bottom plate 31 and extends out of the cartridge bottom plate 31. Along the direction towards the far end, the top surface of the clip inlet end extends obliquely to the direction far away from the clip bin bottom plate 31 to form a plane, so that the tail part of the ligation clip 13 to be inserted is smoothly guided to rise, and the ligation clip 13 to be inserted cannot be clamped. Of course, the top surface of the clamping end can be an arc surface in other embodiments. The top surface of the clip outlet end is a plane parallel to the clip bin bottom plate 31. The top surface of the part between the clamping inlet end and the clamping outlet end is a plane and is flush with the top surface of the clamping outlet end.

In the process that the ligation clamp 13 to be inserted enters the jaw 9, the head of the clip needs to be pushed to abut against the closed tail of the ligation clamp 13 to be inserted to push the ligation clamp to be inserted into the jaw 9, the insertion clamp boss 312 is arranged, in the process of clamping the clip, the insertion clamp boss 312 can prop up the tail of the ligation clamp 13 to be inserted, the ligation clamp 13 to be inserted is prevented from swinging up and down, the head of the clip is pushed to well act on the closed tail of the ligation clamp 13 to be inserted, and the clip feeding is stable; meanwhile, the clamping outlet end of the clamp inlet boss 312 extends out of the bottom plate of the clamping bin, so that the clamp can be clamped into the jaw in a better stable manner. Of course, in other embodiments of the present invention, the clip-out end of the clip-in boss 312 may be flush with the distal end of the cartridge floor.

Thus, in this embodiment, during clip feeding, the closed tail of the clip 13 to be inserted into the clip is supported by the clip inserting end of the clip inserting boss 312, and is held in a horizontal posture by the portion between the clip inserting end and the clip ejecting end. In the present embodiment, the clamping outlet end of the clamping boss 312 is a cantilever structure, but the present invention is not limited thereto, and the clamping outlet end of the clamping boss 312 can be connected to the cartridge bottom plate 31 through a connecting member.

Further, in this embodiment, as shown in fig. 2 and fig. 4, two bosses are disposed in the middle of the magazine bottom plate 31 along the clip feeding direction, one of the bosses is the clip entering boss 312 already discussed above, the other boss is the clip feeding boss 313, the clip feeding end of the clip feeding boss 313 is located at the proximal end of the magazine bottom plate 31, and the clip discharging end of the clip feeding boss 313 is located at a position close to the distal end in the middle of the magazine bottom plate 31 in the left-right direction, that is, the extension length of the clip feeding boss 313 is greater than the length of the magazine bottom plate 31 where more than half of the ligation clips 13 are located in all the ligation clips 13. In this manner, the clip feed tab 313 functions to improve stability during distal advancement of most ligation clips at the proximal side.

The distance between the first pressing part and the second pressing part is smaller than the length of the ligature clamp, so that continuous pressing force is provided for the ligature clamp, and the clamp feeding stability is improved.

Preferably, a pressing table 323 which is arranged along the clip feeding direction and protrudes towards the interior of the clip bin 3 is arranged at the side part of the clip bin top plate 32, the pressing table 323 is arranged corresponding to the clip entering boss 312 according to the position relation, and the clip outlet end of the pressing table 323 is positioned at the far end of the clip bin top plate 32; in the clip feeding process, the closed tail of the clip 13 to be inserted is supported by the clip inlet end of the clip inserting boss 312, and simultaneously, the clamping column at the top of the clip 13 to be inserted is pressed by the pressing table 323. The phenomenon that the ligation clip to be inserted into the clamp swings upwards when the clip is delivered is prevented, and the clip delivery is stable. Further, in the clip feeding process, the closed tail of the clip 13 to be inserted is supported by the clip inlet end of the clip inserting boss 312, and simultaneously, the top clamping column of the clip 13 to be inserted is pressed by the clip inlet end of the pressing table 323.

Conceivably, a pressing table 323 which protrudes towards the interior of the clamping bin along the clamp feeding direction is arranged on one side portion of the clamping bin top plate 32, so that upward deflection of the ligation clamp to be clamped can be prevented when the clamp is fed, and the clamp feeding is stable. Certainly, the pressing tables 323 which protrude towards the interior of the clip bin along the clip feeding direction are arranged on two side portions of the clip bin top plate 32, so that upward deflection of the ligation clip to be inserted can be prevented when the clip is fed, and the clip feeding is stable.
