[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0033] like Figure 1 As shown, a suture needle assembly includes a housing 1 and a cover 2 covering the housing 1.

[0034] The box body 1 includes a thread loading area located near the box cover 2 for accommodating the suture 5 and a needle loading area located on the other side for accommodating the suture needle 4. The head of the suture 5 is fixed to the suture needle 4 to form a threaded suture needle, and a thread opening 101 for the suture 5 to pass through is provided between the thread loading area and the needle loading area.

[0035] The center of the suture area is provided with a spirally arranged suture partition 102 to form a spirally arranged suture groove 103 for installing the suture 5. The corner of the suture partition 102 is rounded to form a suture groove 103 with a rounded corner. The head of the suture groove 103 has an inlet 104 for the suture 5 to enter. The suture needle 4 enters the suture groove 103 after passing through the threading port 101 and the inlet 104, and is spirally arranged along the suture groove 103. The rounded corner facilitates the smooth entry and exit of the barbed suture 5. The height of the suture partitions 102 is equal. After the cover 2 is installed, the top of the suture partition 102 fits tightly with the cover 2 to ensure that the suture 5 will not deviate from the suture groove 103 during use and interfere with the suture 5 in the suture groove 103 on the other side.

[0036] A wire-laying side plate 105 is provided protruding from the edge of the wire-laying area. The wire-laying side plate 105 is located outside the wire-laying partition 102. The protrusion height of the wire-laying side plate 105 is less than the protrusion height of the wire-laying partition 102 so that a wire-laying opening is formed between the two. Since the suture 5 has a certain toughness in the actual wire-laying operation, especially the suture 5 with barbs, it cannot be simply wound by pulling. The wire can be effectively laid and installed by pressing and pulling the wire through the wire-laying opening.

[0037] In use, first, pass the tail of the suture needle 4 through the threading port 101, then install the suture needle 4 in the needle loading area, and gently pull the suture 5 through the thread inlet 104 into the thread loading groove 103 formed by the thread loading partition 102 and spirally arrange it along the thread loading groove 103. At the same time, the thread is effectively installed by pressing and pulling the thread through the thread laying port. Finally, the box cover 2 is placed on the box body 1. This application uses the spiral structure of the thread loading groove 103 to install the suture 5, so that it is spirally arranged. When using the suture 5, it moves along the thread loading groove 103, which can effectively avoid the suture 5 from knotting, getting stuck, or not being able to be pulled out. At the same time, the thread laying port formed by the thread loading partition 102 with different heights and the thread laying side plate 105 can effectively pull the suture 5 to install it in place.

[0038] In some examples, such as Figures 4-6 As shown, the needle loading area is provided with a needle loading slot 106 for inserting the suture needle 4. The groove wall of the needle loading slot 106 has at least three positioning points 107 protruding out. The at least three positioning points 107 are distributed on both sides of the suture needle 4 to limit the suture needle 4 within the needle loading slot 106. In this embodiment, there are three positioning points 107. Since the suture needle 4 is arc-shaped, the three positioning points 107 form a triangular distribution to fix the suture needle 4 located in the needle loading slot.

[0039] In some examples, such as Figures 4-6As shown, the needle loading area includes a base 108 and a first protrusion 109 and a second protrusion 110 protruding from the base 108 toward the side opposite to the cover 2. The first protrusion 109 and the second protrusion 110 are spaced apart and a needle loading groove 106 is formed between them. The base 108 forms the bottom of the needle loading groove 106, which is used to support the middle part of the suture needle 4. The base 108 extends to both sides to form wings 111 for supporting both ends of the suture needle 4. The base 108 and the wings 111 jointly support the suture needle 4, which further improves the stability of the suture needle 4 installation. One of the wings 111 extends to form an indicator 115, which is used to indicate the direction of the needle tip of the suture needle 4 to prevent the suture needle 4 from being installed backwards. At the same time, the indicator 115 is lower than the wing 111, that is, when the wing 111 supports the suture needle 4, the indicator 115 does not contact the suture needle 4.

[0040] In some examples, such as Figures 4-6 The base 108 shown is recessed at one end near the suture opening 101 to form a suture groove 112 communicating with the suture opening 101. The height of the suture groove 112 is greater than the diameter of the suture 5. The suture 5 enters the suture opening 101 along the suture groove 112. The suture groove 112 can guide the suture 5. During this process, the suture 5 fits against the groove wall of the suture groove 112. The high height of the suture groove 112 can confine the suture 5 inside it. The groove wall of the suture groove 112 is arc-shaped, and its curvature is approximately the same as that of the suture needle 4.

[0041] In some examples, such as Figure 2 As shown, the cover 2 protrudes towards the body 1 to form several spaced combing plates 201. The combing plates 201 can extend laterally or longitudinally and are correspondingly arranged on the inner side of the mounting plate 102. The wiring side plate 105 is located on the outer side of the mounting plate 102. The spacing between adjacent combing plates 201 can be equal or unequal. The protrusion height of the combing plates 201 is less than the protrusion height of the mounting plate 102. That is, after the cover 2 and the body 1 are assembled, there is a gap between the combing plates 201 and the body 1. This gap is slightly larger than the diameter of the sewing thread 5. Thus, when installing a longer specification sewing thread 5, the combing plates 201 can squeeze the sewing thread 5 (i.e. the tail of the sewing thread 5) coiled in the middle of the body 1 as much as possible onto the same plane, reducing the situation of the sewing thread lifting up and tangling.

[0042] In some examples, such as Figure 1 and Figure 4 As shown, the needle loading area protrudes from the box cover 2, and the box cover 2 and the box body 1 are covered with a cap 3 for protecting the suture needle 4. The suture needle 4 can be effectively protected and isolated before use. Both the box cover 2 and the box body 1 have limiting steps for limiting the cap 3.

[0043] In some examples, such as Figure 2 and Figure 3 As shown, the lid 2 and the body 1 are respectively provided with insertion posts 202 and insertion slots 113 for insertion of the insertion posts 202. The insertion posts 202 and insertion slots 113 cooperate to fix the lid 2 and the body 1. The number of insertion posts 202 and insertion slots 113 can be, but is not limited to, one, two or three, etc. A number of insertion posts 202 and insertion slots 113 correspond one-to-one, and each insertion post 202 is inserted into its corresponding insertion slot 113. In this embodiment, the number of insertion posts 202 and insertion slots 113 is four, and they are symmetrically distributed.

[0044] In some examples, such as Figure 2 and Figure 3 As shown, the plug post 202 is a cylindrical structure, and the plug groove 113 is a polygonal structure tangent to the plug post 202. The plug post 202 is inserted into the plug groove 113 and is tangentially engaged with the plug groove 113.

[0045] In some examples, such as Figure 2 and Figure 3 As shown, the lid 2 and the body 1 are respectively provided with positioning blocks 203 and positioning grooves 114 that cooperate with the positioning blocks 203. Preferably, the positioning grooves 114 are located on the body 1 and at the inlet 104, and the positioning blocks 203 are located on the lid 2. When the thread is installed (at this time the lid 2 is not installed), the positioning blocks 203 on the lid 2 will not affect the diameter of the inlet 104, thereby avoiding affecting the installation process of the suture 5. When the lid 2 is closed, the head end of the thread mounting partition 102 and the positioning blocks 203 are distributed on both sides of the inlet 104. After the suture 5 enters the inlet 104, it deflects towards the head end of the thread mounting partition 102 to enter the thread mounting groove 103. Therefore, the positioning blocks 203 located on the other side of the inlet 104 will not press on the suture 5 and cause jamming during the installation of the lid 2.

[0046] In some examples, the edge of the lid 2 protrudes towards the body 1 to form a side baffle 204, which corresponds to the thread-mounting partition 102 to confine the suture line 5 within the suture area.

[0047] Working principle:

[0048] In use, first, pass the tail of the suture needle 4 through the threading port 101, then insert the suture needle 4 into the needle holder slot 106. The three positioning points 107 on the wall of the needle holder slot 106 fix the suture needle 4. The base 108 and the wings 111 support the suture needle 4 together. Gently thread the suture 5 through the thread inlet 104 into the thread holder groove 103 formed by the thread holder partition 102 and arrange it spirally along the thread holder groove 103. When in use, the suture 5 moves along the thread holder groove 103. The movement effectively prevents the suture 5 from knotting or getting stuck. At the same time, the suture opening formed by the suture mounting partitions 102 and the suture mounting side plate 105 of different heights is used to effectively pull the suture 5 to install it in place. Then, with the assistance of the positioning block 203 and the positioning groove 114, the insertion post 202 is inserted into the insertion groove 113 to realize the assembly of the box body 1 and the box cover 2. Finally, the cap 3 is tightly installed on the front end of the box body 1 and the box cover 2 to protect the suture needle 4.
