[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 The present invention provides a nail cartridge assembly that is easy to install, including a housing 1.

[0027] Reference Figure 4As shown, a first slider 2 is provided inside the housing 1. An installation structure 3 is installed inside the housing 1. The installation structure 3 includes a first mounting block 301, a first stop block 302, a spring 303, an inner tube 304, an outer tube 305, a second slider 306, and a limiting block 307. The outer wall of the first mounting block 301 is located inside the housing 1. The first stop block 302 passes through the interior of the first mounting block 301. A spring 303 is fixed to one side of the first stop block 302. Inner tubes 304 are provided on both sides of the spring 303. An outer tube 305 is provided outside the inner tube 304. The second slider 306 is located inside the first mounting block 301. 06. The second slider 306 extends to one side outside the first mounting block 301 and is fitted with a limiting block 307. The first mounting block 301 and the first stop block 302 are not in contact but are not connected. The first stop block 302 is symmetrical. The first stop block 302 is fixedly connected to the inner tube 304 and the outer tube 305. The inner tube 304 and the outer tube 305 are slidably connected. The first mounting block 301 and the second slider 306 are slidably connected. The first stop block 302 and the second slider 306 are in contact but are not connected. The first mounting block 301 and the limiting block 307 are in contact but are not connected. The second mounting block 4 is installed on one side of the first mounting block 301 extending to the outside of the housing 1.

[0028] By moving the limiting block 307, the spring 303 is retracted under pressure, thereby causing the first stop block 302 to retract. The inner tube 304 slides inside the outer tube 305 to prevent the retraction position of the first stop block 302 from changing, thus making it easy to remove or install the first mounting block 301 from the inside of the housing 1, and realizing that the device has the function of easy installation and disassembly.

[0029] Reference Figure 2 and Figure 3 As shown, the second mounting block 4 has a snap-fit ​​structure 5 inside. The snap-fit ​​structure 5 includes a drive block 501, a limiting groove 502, a chamber 503, a third mounting block 504, a reinforcing block 505, a nail cavity 506, a stitching nail 507, and a support member 508. One side of the drive block 501 is installed inside the second mounting block 4. Each drive block 501 has a limiting groove 502 inside. The bottom of the limiting groove 502 is provided with a chamber 503. The bottom surface is covered with a third mounting block 504, and a reinforcing block 505 is attached to one side of the compartment 503. The interior of the compartment 503 is provided with a nail cavity 506, and a sewing nail 507 is installed inside the nail cavity 506. A support member 508 is provided on the outer wall of the compartment 503. The limiting grooves 502 are staggered, and the sewing nails 507 are staggered. The compartment 503 and the support member 508 are in contact but not connected, and the third mounting block 504 and the support member 508 are in contact but not connected.

[0030] The drive block 501, the chamber 503, and the support 508 are all metal products (e.g., stainless steel, titanium alloy, etc.), featuring high strength, corrosion resistance, and easy cleaning. The third mounting block 504 is a plastic product with good flexibility. By pulling the chamber 503, the third mounting block 504 deforms under pressure and enters the interior of the support 508, simultaneously driving the reinforcing block 505 into the interior of the support 508, increasing its stability after installation and preventing the chamber 503 from falling off due to accidental contact during surgery. The chamber 503 is a disposable item. This installation method is suitable for environments with high hygiene requirements and can reduce manufacturing costs, achieving the functions of easy maintenance, easy installation, and reduced manufacturing costs for the device.

[0031] In summary, as Figures 1-5 As shown, in use, when the staple cartridge assembly is in use, the limiting block 307 is moved, causing the second slider 306 to move towards the first stop 302. The second slider 306 then applies pressure to the first stop 302, causing the spring 303 to retract. This causes the inner tube 304 to slide inside the outer tube 305, thereby causing the first stop 302 to retract into the first mounting block 301. When the first stop 302 is fully retracted into the first mounting block 301, the first mounting block 301 can be removed from the inside of the housing 1 for inspection or replacement. When installation is required, the limiting block 307 is moved again. When the first stop 302 aligns with the groove inside the housing 1, the limiting block 307 is released, releasing the pressure of the spring 303. This allows the first stop 302 to pass through the first mounting block 301 and enter the inside of the housing 1, completing the installation. The cartridge body 503 is then placed on the support member 50. Inside the support 508, pressure is applied downwards, causing the third mounting block 504 to move inwards and enter the support 508. This pushes the chamber 503, allowing the reinforcing block 505 to enter the support 508. After this, the pressure on the third mounting block 504 is released, allowing it to be installed. When additional sutures 507 are needed, the chamber 503 is slid forcefully, causing the third mounting block 504 to deform again and be removed. The support 508 has a pusher block inside. The pusher block moves forward via a micro motor inside the handle, causing the first slider 2 to slide inside the housing 1, which acts as a limit. The pusher block causes the sutures 507 to pop out from inside the suture cavity 506, simultaneously causing the drive block 501 to close. The top of the suture 507 touches the limiting groove 502 and retracts, forming a back-loop shape, thus suturing the tissue.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
