DETAILED DESCRIPTION

[0037] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0038] Example 1:

[0039] See also Figures 1 to 7 As shown, this embodiment provides an automatic stapler assembly device for a stapler, comprising: a staple loading assembly, a staple conveying assembly, a staple assembly and a stapler fixing seat 3 sequentially arranged along a conveying path of staples 4 .

[0040] Generally speaking, the nail transfer assembly includes a nail feeding guide rail 1 for receiving the upper nail assembly and a nail feeding vibration base for supporting the nail feeding guide rail 1; the nail arranging assembly includes a nail arranging guide rail 2 for receiving the nail feeding guide rail 1, a nail arranging vibration base for supporting the nail arranging guide rail 2, and a nail arranging frame group for arranging the staples 4 arranged above the nail arranging guide rail 2; the nail magazine fixing seat 3 is arranged at the tail end of the nail arranging guide rail 2 away from the nail feeding guide rail 1, and the nail arranging guide rail 2 extends into the nail magazine fixing seat 3.

[0041] Based on the above structure, an optional implementation is given as an example, in which the nail feeding assembly uses a vibration plate 200; the vibration plate 200 is connected to the nail feeding guide rail 1 through a material channel 201. The vibration plate 200 here can be any mature means in the existing technology, and this embodiment does not impose an absolute limitation on its specific structure and implementation principle. It should be noted that, regarding the coordination between the vibration disk 200 and the nail feeding guide rail 1 of this embodiment, the material channel 201 is located above the nail feeding guide rail 1 and can enter the nail feeding guide rail 1 by falling. At this time, it cannot be guaranteed that each staple 4 on the material channel 201 will fall accurately on the nail feeding guide rail 1. For the staples 4 that have not fallen into the nail feeding guide rail 1, they can enter the vibration disk 200 again. In order to improve the alignment rate of the staples 4 that fall from the material channel 201 to the nail feeding guide rail 1, optionally, the end of the nail feeding guide rail 1 corresponding to the material channel 201 to receive the staple 4 is cut so that the width of the end is smaller than that of the rest of the nail feeding guide rail 1, that is, the width of this part of the nail feeding guide rail 1 is smaller than the width between a pair of staple legs 42 of the staple 4.

[0042] Furthermore, more specifically, the staple 4 is in the shape of a commonly used U-shaped titanium staple, which includes a staple back 41 and a pair of staple legs 42 connected to the staple back 41. For the staple 4 that enters the staple feed guide 1 through the upper staple assembly, it can be ensured that the staple back 41 is always in contact with the staple feed guide 1, while the pair of staple legs 42 may be tilted relative to the staple back 41 toward the upper staple assembly, or may be tilted toward the entire staple guide 2, or may be tilted neither toward the entire staple guide 2 nor toward the upper staple assembly. However, based on the staple cartridge 300 set in the staple cartridge fixing seat 3 of this embodiment, the pair of staple legs 42 of the staple 4 loaded into the staple cartridge 300 need to be tilted relative to the staple back 41 toward the side facing away from the upper staple assembly. The staple 4 loaded into the staple cartridge 300 in this state can then be adjusted to meet the usage requirements through the subsequent pushing operation of the staple cartridge 300. Therefore, for the staples 4 entering the staple magazine 300 through the staple feed guide rail 1, this embodiment adds a whole staple assembly, which is mainly used to adjust the inclination direction of a pair of staple legs 42 of the staples 4 relative to the staple back 41 before entering the staple magazine 300.

[0043] In this regard, regarding the nail frame group used in this embodiment, an optional implementation is given as an example in conjunction with the accompanying drawings, which includes a nail block 5 suitable for cooperating with the nail guide rail 2 to form a nail cavity 8 and a fixing seat 6 for fixing the nail block 5; the end face of the nail block 5 facing the nail guide rail 2 is an inclined surface 52; and the inclined surface 52 is gradually distributed downward from the side end adjacent to the nail feeding guide rail 1 to the side end away from the nail feeding guide rail 1.

[0044] The fixing base 6 can be fixed to the side wall of the whole nail guide rail 2 by, for example, but not limited to, screw fastening. As for the overall shape of the fixing base 6, it includes a pair of fixing brackets 61 located on both sides of the whole nail guide rail 2 and a connecting bracket 62 for connecting the pair of fixing brackets 61. In this way, the pair of fixing brackets 61 and the connecting bracket 62 form a U-shaped accommodating cavity 63 for fixing the whole nail block 5; the accommodating cavity 63 has a connecting opening open to the whole nail guide rail 2; and the whole nail block 5 is fixed in the accommodating cavity 63 by a bolt 71. The depth of the accommodating cavity 63 along the direction perpendicular to the extension of the whole nail guide rail 2 is greater than the height of the whole nail block 5 along the direction perpendicular to the whole nail guide rail 2. More specifically, the whole nail block 5 is provided with a T-shaped slot 51 for fitting the bolt 71; and the fixing base 6 is provided with a matching hole suitable for the bolt 71 to pass through. The bolt 71 cooperates with the butterfly nut 72 to achieve the fastening fit between the whole nail block 5 and the fixing base 6. In this structure, by adjusting the tightness of the butterfly nut 72 and the bolt 71 , the position of the whole nail block 5 in the accommodating cavity 63 can be adjusted, thereby adjusting the gap between the whole nail block 5 and the whole nail guide rail 2 .

[0045] Furthermore, the end surface of the nail assembly guide rail 2 facing the inclined surface 52 of the nail assembly block 5 is an inclined guide surface 21; the side end of the inclined guide surface 21 adjacent to the nail feeding guide rail 1 is higher than the side end away from the nail feeding guide rail 1.

[0046] Based on the above situation, further speaking, the whole nail cavity 8 formed by the whole nail block 5 and the whole nail guide rail 2 has a gradually decreasing trend from the adjacent nail feed guide rail 1 to the away from the nail feed guide rail 1 along the height perpendicular to the conveying direction of the anastomotic staple 4. It should be explained here that since the whole nail block 5 only forms a limitation on the size of the whole nail cavity 8 in the height direction perpendicular to the conveying direction of the anastomotic staple 4, that is to say, it only affects the size of the conveying cavity of the nail back 41, and there is no change in the conveying interval of a pair of nail legs 42.

[0047] Based on the above structure, when the anastomotic staples 4 pass through, the back of the staples 41 is affected by the height change of the whole nail cavity 8. When the back of the staples 41 is transferred from the whole nail cavity 8 to the area with a smaller height of the whole nail cavity 8, the transfer speed of the back of the staples 41 will be relatively reduced, while the transfer speed of the pair of staple legs 42 will be relatively accelerated as the end surface of the inclined surface 52 of the whole nail guide rail 2 toward the whole nail block 5 is the inclined guide surface 21. In this way, the fast and slow coordination will cause the pair of staple legs 42 to be inclined toward the side of the staple magazine 300 relative to the back of the staples 41. Therefore, under the coordination of the whole nail block 5 and the whole nail guide rail 2 of this embodiment, the shape of the anastomotic staples 4 on the whole nail guide rail 2 can be adjusted to be unified into the same shape to meet the state requirements for entering the staple magazine 300. In this regard, it should be noted that, for the staples 4 entering the staple magazine 300, on the basis of maintaining the pair of staple legs 42 tilted toward the side of the staple magazine 300 relative to the staple back 41, the specific tilt angle is not required to be completely consistent for each staple 4, and there can be a certain small range of differences between the multiple staples 4. Such differences will be corrected by the abutment and cooperation of each adjacent staple 4 during the process of the multiple staples 4 entering the staple magazine 300 one by one, so that each adjacent staple 4 can be completely in contact with each other.

[0048] In a specific optional implementation, the staple feed guide rail 1 used in this embodiment may optionally be a guide rail with an inclined distribution within a certain small range, and the inclined state is that the end thereof facing the upper staple assembly is higher than the end thereof connected to the whole staple guide rail 2, thereby improving the transmission efficiency of the staples 4 on the staple feed guide rail 1. As for the whole staple guide rail 2, the portion of the whole staple guide rail 2 located on the side of the whole staple block 5 facing the staple feed guide rail 1 has an inclined distribution within a certain small range as a whole, and the inclined state of this portion is connected to the staple feed guide rail 1, that is, after this portion of the whole staple guide rail 2 is connected to the staple feed guide rail 1, it continues to extend along the inclined state of the staple feed guide rail 1, thereby ensuring the smooth flow of the staples 4 between the staple feed guide rail 1 and the whole staple guide rail 2. In this regard, it is also necessary to explain that regarding the angle of inclination of this portion of the nail guide rail 2, since the end surface of the nail guide rail 2 facing the inclined surface 52 of the nail block 5 is an inclined guide surface 21, as illustrated in the accompanying drawings, both the inclined surface 52 of the nail block 5 and the inclined guide surface 21 of the nail guide rail 2 are S-shaped. This means that the inclined guide surface 21 of the nail guide rail 2 is not directly connected to the inclined position at the portion where it connects to the nail feed guide 1. Furthermore, the portion of the nail guide rail 2 located on the side of the inclined guide surface 21 facing the staple cartridge 300 can also be configured to be inclined, with the end of the nail guide rail 3 in this portion facing away from the staple cartridge 300 being inserted into the staple cartridge. This means that the staples 4 are transported along the nail guide rail 2 until they enter the staple cartridge 300. Therefore, the entire nail guide rail 2 can be understood as a generally inclined guide rail that forms an S-shaped transition at the portion corresponding to the staple lumen 8 of the nail block 5.

[0049] In addition, based on the above situation, in order to improve the smoothness of the transmission process of the staples 4 on the whole nail guide rail 2, the two end faces of the inclined guide surface 21 of the whole nail guide rail 2 along the transmission direction of the staples 4 are connected with the rest of the whole nail guide rail 2 in a circular arc.

[0050] Furthermore, it is important to note that the staple feeding vibration base includes a staple feeding support 91 for securing the staple feeding guide 1 and a staple feeding vibrator 92 disposed within the staple feeding support 91. The staple assembly vibration base includes a staple assembly support 93 for securing the staple assembly guide 2 and a staple assembly vibrator 94 disposed within the staple assembly support 93. Both the staple feeding vibrator 92 and the staple assembly vibrator 94 are designed to ensure smooth transport of the staples 4 along the staple feeding guide 1 and the staple assembly guide 2.

[0051] In summary, for the stapler automatic stapling device of this embodiment, the staple transfer assembly, the staple assembly, and the staple cartridge fixing seat 3 cooperate to allow the staples 4 to be directly loaded into the staple cartridge 300 under the guidance of the guide rail in the vibration mode. In this way, there is no longer a need for a special clamping assembly or transfer assembly to transfer and align the staples 4. During this process, the state of the staples 4 loaded into the staple cartridge 300 can be adjusted by simply cooperating with the staple assembly block 5 and the staple assembly guide rail 2, so that the staples 4 can be loaded into the staple cartridge 300 according to the desired state. Therefore, the present invention simplifies the structure of the overall stapling device, thereby simplifying the stapling process of the staples 4, reducing the stapling difficulty, and improving the stapling efficiency.

[0052] Example 2:

[0053] Based on the automatic stapling device for a stapler of Example 1, the nail feeding vibration base of the automatic stapling device for a stapler provided in this embodiment is further provided with a counting structure; specifically, the counting structure includes a support seat 101 fixed on the nail feeding guide rail 1 and a counter 102 provided on the support seat 101 and facing the nail feeding guide rail 1.

[0054] In this embodiment, the counter 102 is designed to count the number of staples 4 on the staple feed guide 1, so that loading can be paused after the required number of staples 4 for a staple cartridge 300 passes through the staple feed guide 1, and restarted after a new staple cartridge 300 is loaded. In this way, during the loading and unloading process of the staple cartridge 300, there is no need for manual intervention in the state of the staple loading assembly. Instead, the operation state of the staple loading assembly can be adjusted by counting the number of staples 4 on the staple feed guide 1 by the counter 102 in combination with, for example, a controller corresponding to the counter 102. The counter 102 herein can be any mature means in the prior art, and this embodiment does not impose an absolute limitation on its specific model.
