Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a chuck for loading needles into the head assembly of an automatic suture machine. Background Technology

[0002] In minimally invasive surgery, some obese patients have thicker subcutaneous fat, resulting in small and deep puncture holes, limited field of vision, and large suture arcs, making suturing difficult and preventing precise suturing of the peritoneum and fascia layers. This can easily lead to abdominal wall defects at the puncture site, ultimately resulting in puncture-hole hernias within the abdominal cavity. In open surgery, the tissues requiring suturing are located deeper, and ordinary instruments cannot reach the suturing sites or fix the tissues properly, making suturing difficult. While existing medical suture devices can achieve the suturing purpose, most have complex structures, are prone to mechanical failure during use, and require complex procedures for surgeons, making the assembly and disassembly of parts difficult and hindering surgical execution.

[0003] However, loading needles into an automatic suture machine is cumbersome and takes a long time. Therefore, it is necessary to connect the suture needles and sutures in advance. However, the pre-connected sutures are prone to tangling for various reasons. Therefore, a component is needed that can regularly twist the sutures. This component should also be able to hold multiple suture needles and staple cartridges to meet various needs. Utility Model Content

[0004] The purpose of this invention is to provide a chuck for loading needles into the head assembly of an automatic suture machine, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a chuck for loading needles into the head assembly of an automatic suture machine, comprising: a chuck assembly and a staple cartridge assembly, wherein the chuck assembly includes a suture limiter and a staple cartridge limiter, a plurality of suture limiters are provided on the surface of the chuck assembly, the plurality of suture limiters are provided on the inner side of the outer edge of the surface, and a staple cartridge limiter is also provided on one side of the surface for engaging the staple cartridge assembly.

[0006] Furthermore, the chuck assembly has two semicircles at both ends and a rectangle in the middle, giving it an overall capsule shape.

[0007] Furthermore, the suture limiter has an L-shaped plate with one end located inside the outer edge of the chuck assembly and fixedly connected to the chuck assembly surface. The other end extends upward from the part in contact with the chuck assembly surface, with the extension height being the same as the thickness of the staple cartridge assembly. After extending upward to this height, it extends outward. The outer side of the suture limiter and the outer edge of the chuck assembly are on the same projection.

[0008] Furthermore, on the semi-circular surfaces at both ends of the chuck assembly, suture limiters are evenly spaced and form a semi-circular arc along the semi-circular surfaces at both ends of the chuck assembly. On the chuck assembly at one end of the chuck assembly, where the staple cartridge assembly is engaged, suture limiters are spaced apart, and the spaced portion at the head of the staple cartridge assembly is wider than the width of the staple cartridge assembly, allowing it to be inserted and removed within this space.

[0009] Furthermore, on the side of the chuck assembly disk surface away from the staple cartridge limiter, the suture limiter extends to the other side along the semi-circular surface at the end of the disk surface, forming a semi-circular arc. The suture limiter forms another semi-circular arc on the disk surface, and the suture limiter away from the staple cartridge limiter forms a complete circle.

[0010] Furthermore, a suture needle limiter is also provided on the disc surface. The suture needle limiter is located on the disc surface away from the suture thread limiter and the staple cartridge limiter. The suture needle limiter is provided with a through hole through which the suture needle can pass, and the inside of this through hole is provided with soft rubber to provide a certain degree of damping.

[0011] Furthermore, a raised connecting post is provided on the disc surface, and a locking block is provided on the connecting post. One end of the suture needle limiter is provided with a locking groove. The locking block and the locking groove cooperate to realize the detachable connection between the suture needle limiter and the connecting post. The other end of the suture needle limiter is also provided with a locking block, so that several suture needle limiters can be detachably connected in sequence.

[0012] Compared with the prior art, this utility model has the following advantages: (1) This utility model can wrap the suture thread around the chuck by the suture thread limiter, preventing the suture thread from getting tangled due to vibration and other reasons, and making it easier for doctors to remove it in time during surgery.

[0013] (2) The present invention uses a staple cartridge limiter to attach the staple cartridge assembly to the chuck. Because the staple cartridge assembly is small, if it is not placed on the chuck, it may be lost due to its small size. Also, after the suture needle inside is connected to the suture thread, there is nowhere to put the suture thread, which may cause tangling. After placing it on the chuck, the suture thread can be wrapped around the chuck to avoid tangling.

[0014] (3) This utility model can place the suture needle on the chuck in advance by using the suture needle limiter. Because the suture needle is smaller in size, it is more likely to be lost. Placing it regularly on the chuck makes it easier for doctors to use. Attached Figure Description

[0018] The components include a chuck assembly 100, a suture limiter 110, a suture needle limiter 120, a staple cartridge limiter 130, a staple cartridge assembly 200, and a suture needle 300. Detailed Implementation

[0019] The purpose of this utility model is to address the shortcomings of existing technologies by providing a chuck for loading needles into the head assembly of an automatic suture machine, specifically achieved through the following technical solution: Reference Figure 1 , Figure 2 , Figure 3 This embodiment provides a chuck for loading needles into the head assembly of an automatic suture machine, comprising a chuck assembly 100 and a staple cartridge assembly 200. The chuck assembly 100 includes a suture limiter 110 and a staple cartridge limiter 130. A plurality of suture limiters 110 are provided on the surface of the chuck assembly 100, and the plurality of suture limiters 110 are located on the inner side of the outer edge of the surface. A staple cartridge limiter 130 is also provided on one side of the surface of the chuck assembly for engaging the staple cartridge assembly 200. When the staple cartridge assembly 200 is engaged on the surface of the chuck assembly, a baffle is provided at its rear end to block the staple cartridge assembly 200 and further fix the staple cartridge assembly 200.

[0020] Reference Figure 1 , Figure 2 , Figure 3 The chuck assembly 100 has two semicircles at both ends and a rectangle in the middle, and its overall shape is capsule-like. The two ends of the chuck are arc-shaped to facilitate the wrapping of the suture thread.

[0021] Reference Figure 1 , Figure 2 , Figure 3 The suture limiter 110 has an L-shaped cross-section. One end of the suture limiter is located inside the outer edge of the chuck assembly 100 and is fixedly connected to the chuck assembly 100. The other end extends upward from the part in contact with the chuck assembly 100, with the extension height being the same as the thickness of the staple cartridge assembly 200. After extending upward to this height, it extends outward. The outer side of the suture limiter 110 and the outer edge of the chuck assembly are on the same projection. This structure facilitates suture winding because the L-shaped suture can be easily caught at its bend, making it easier for doctors or other staff to perform preliminary preparations.

[0022] Reference Figure 1 , Figure 2 , Figure 3On the semi-circular surfaces at both ends of the chuck assembly 100, suture limiters 110 are evenly spaced and form a semi-circular arc along the semi-circular surfaces at both ends of the chuck assembly 100. On the chuck assembly 100 at one end of the chuck assembly 100, where it is positioned to engage with the staple cartridge assembly 200, suture limiters 110 are spaced apart, and the spaced portion at the head of the staple cartridge assembly 200 is wider than the width of the staple cartridge assembly 200, allowing it to be inserted and removed within this space.

[0023] Reference Figure 1 , Figure 2 , Figure 3 On the side of the chuck assembly 100 away from the staple cartridge limiter 130, the suture limiter 110 extends to the other side along the semi-circular surface at the end of the chuck assembly 100, forming a semi-circular arc. The suture limiter 110 forms another semi-circular arc on the chuck assembly 100. The suture limiter 110 away from the staple cartridge limiter 130 forms a complete circle, allowing the suture to be wrapped around it, increasing the length of suture that the chuck can store, and adapting to different surgical needs.

[0024] Reference Figure 1 , Figure 2 , Figure 3 The tray is also equipped with a suture needle limiter 120. The suture needle limiter 120 is located on the tray away from the suture line limiter 110 and the staple cartridge limiter 130. The suture needle limiter 120 is provided with a through hole through which the suture needle 300 can pass. The inside of this through hole is provided with soft rubber to provide a certain damping. The suture needle 300 can be stably locked in this through hole. When needed, the doctor can directly pull it out. Because of the damping provided by the soft rubber, the suture needle 300 will not leave the restriction of the suture line limiter 110 due to vibration, falling or other reasons.

[0025] Reference Figure 1 , Figure 2 , Figure 3 The tray has a raised connecting post with a locking block. One end of the suture needle limiter 120 has a locking groove. The locking block and the locking groove cooperate to achieve a detachable connection between the suture needle limiter 120 and the connecting post. The other end of the suture needle limiter 120 also has a locking block, so that several suture needle limiters 120 can be detachably connected in sequence. Different numbers of suture needle limiters 120 can be set as needed. Different numbers of suture needle limiters 120 can be pre-configured according to different needs to adapt to different surgical requirements.
