Description

Technical Field

[0001] This utility model belongs to the field of laparoscopic anastomosis device assembly technology, specifically a laparoscopic anastomosis device that facilitates the connection of rod components and device body components. Background Technology

[0002] Laparoscopic staplers are indispensable high-end medical devices in modern minimally invasive surgery. They replace traditional manual suturing with titanium staples for mechanical anastomosis, significantly improving surgical efficiency and safety standards, and playing a core role in complex surgeries in the gastrointestinal, cardiothoracic, and hepatobiliary fields. Currently, in stapler manufacturing, during the connection process between the stapler body assembly and the rod assembly, the posterior sleeve is used as the reference positioning component. Components such as the slider spring, firing rod, and blade holder lack limiting mechanisms in the rod assembly. Theoretically, the slider spring and blade holder are helical pairs, and the firing rod is a sliding pair. There are two fourth-order pairs and one fifth-order pair, meaning the blade holder and slider spring have axial movement and circumferential rotation, and the firing rod has one degree of freedom in axial movement. Axial movement is the degree of freedom that affects assembly.

[0003] During the production and assembly process, workers first need to control the slider spring with their palm, then use one thumb to hold the tool holder, and the other hand to control the position of the firing rod. After the preset assembly conditions are met, the slider spring is used to hold the body assembly in place, and a tilting force is applied. The slider spring is then pulled into the groove of the body, and the tool holder and firing rod are positioned. Finally, the firing rod and tool holder are secured to the body assembly, thus assembling the body assembly and the rod assembly. During the assembly process, the force on the slider spring may cause slight displacement of the tool holder and firing rod, resulting in misalignment. A screwdriver must then be used to correct the position, ensuring the firing rod is properly engaged in the rack. This assembly method is inefficient and requires skilled workers, causing numerous inconveniences to production. Utility Model Content

[0004] The purpose of this invention is to provide a laparoscopic anastomosis device that facilitates the connection between the rod assembly and the device body assembly, thereby addressing at least one aspect of the problems and defects mentioned in the background art.

[0005] A laparoscopic anastomosis device that facilitates the connection of rod components and device body components includes a limiting lower mold. A first limiting block is provided on one side of the top of the limiting lower mold, and a receiving groove and a second limiting block are provided on the other side. The receiving groove is located at one end of the limiting lower mold, and the second limiting block is located at the other end of the limiting lower mold. A first limiting groove is provided on the top of the first limiting block, and a second limiting groove is provided on the top of the second limiting block.

[0006] The upper limiting mold is movably installed on the top of the second limiting block. The upper limiting mold has a third limiting groove that runs vertically through it. A spring guide rail is provided in the third limiting groove. The first end of the spring guide rail is located at the end away from the receiving groove and is inclined towards the receiving groove.

[0007] Furthermore, the receiving slot is designed to be rectangular.

[0008] Furthermore, the first limiting groove is set to an arc shape.

[0009] Furthermore, the upper limiting mold is movably mounted on the second limiting block via a hinge structure.

[0010] Furthermore, it also includes a hand press, with the lower limiting mold installed on the top of the base of the hand press.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This solution features a lower limiting mold with a receiving groove, a first limiting block, and a second limiting block. The first limiting block has a first limiting groove, and the top of the second limiting block has a second limiting groove. A upper limiting mold is movably mounted on the top of the second limiting block. A third limiting groove is formed on the upper limiting mold. The handle of the laparoscopic anastomosis device is placed in the first limiting groove, the front end of the device is placed in the second limiting groove, the rear end is placed in the receiving groove, and the connecting part of the rod assembly is placed in the third limiting groove. Force is applied to the connecting part of the rod assembly to press it into the device body, connecting the connecting part of the rod assembly to the front end of the device body. The receiving groove, the first limiting groove, and the second limiting groove limit the device body, and the third limiting groove limits the connecting part of the rod assembly, thereby improving the stability when connecting the device body and the rod assembly.

[0013] 2. A spring guide rail is provided in the third limiting groove. Since the first end of the spring guide rail is located at the end away from the receiving groove and is inclined towards the receiving groove, when the connecting part of the rod assembly is pressed down, the spring on the connecting part of the rod assembly will slide into the groove of the body along the spring guide rail. This design makes it easier to install the spring when the body assembly and the rod assembly are connected. Attached Figure Description
