Description

Technical Field

[0001] This utility model relates to the field of cutting stapler technology, and in particular to a replaceable stapling assembly for cutting staplers. Background Technology

[0002] In surgical procedures, the stapler is a commonly used medical device for quickly and accurately cutting and anastomosing tissue. The stapling assembly, a key component of the stapler, contains an anvil and a cartridge. During surgery, the anvil and cartridge must precisely engage to push out and insert the staples into the tissue, achieving tissue anastomosis.

[0003] However, existing replaceable stapling devices have some shortcomings. Firstly, when not in use, the anvil and cartridge of the stapling device lack effective restraint, making them prone to accidental opening. This could lead to damage or loss of the staples, potentially affecting the smooth progress of the surgery and increasing surgical risks. Secondly, the installation and removal of existing stapling devices are relatively complex, hindering doctors from quickly replacing them and reducing surgical efficiency. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the prior art by proposing a replaceable stapling assembly for cutting staplers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A replaceable stapling assembly for a stapler includes a stapler body 1. A stapling assembly body 4 is mounted on the stapler body 1 via a mounting mechanism. The mounting mechanism facilitates the installation and removal of the stapling assembly, making it easy to replace. A limit mechanism is provided on the stapling assembly body 4 to limit its movement and prevent the anvil in the stapling assembly body 4 from opening when not in use. The mounting mechanism includes a mounting box 22, which is fixedly mounted to the end of the stapler body 1. A mounting block 210 is inserted into the inner wall of the mounting box 22. The stapling assembly body 4 is fixedly mounted on the mounting box. At one end of block 210, a sliding groove 26 is provided inside the mounting box 22. The sliding groove 26 is square in shape and is used to support the sliding of the limiting block 27. The inner wall of the sliding groove 26 is slidably provided with the limiting block 27. The limiting block 27 is used to support the installation of the insert block 28. One end of the limiting block 27 is provided with the insert block 28, and one end of the insert block 28 penetrates the inner wall of the mounting box 22. The insert block 28 is used to be inserted into the slot 23, thereby achieving the purpose of fixing the fixing block 210 into the mounting box 22. A spring 29 is fixedly installed on the inner wall of the sliding groove 26. One end of the spring 29 is fixedly connected to the limiting block 27. The spring 29 is used to apply force to the insert block 28.

[0022] The limiting mechanism includes a motor 33, which is fixedly installed on the ordering component body 4. The motor 33 has forward and reverse rotation functions. The motor 33 is used to drive the lead screw 35 to rotate. The lead screw 35 is fixedly installed on the shaft end of the motor 33. The lead screw 35 is used to drive the slider 34 to slide linearly along the surface of the ordering component body 4. The slider 34 is threadedly connected to the lead screw 35. The slider 34 slides on the ordering component body 4. The slider 34 is used to support the installation of the connecting rod 31. The connecting rod 31 is fixedly installed at the bottom end of the slider 34. A limiting plate 32 is fixedly installed at one end of the connecting rod 31. The limiting plate 32 is used to facilitate the closure of the anti-pin seat and the ordering in the ordering component body 4.

[0023] In detail, the mounting block 210 is cylindrical in shape, and its cross-sectional dimensions are adapted to the cross-sectional dimensions of the inner wall of the mounting box 22.

[0024] Furthermore, two positioning rods 24 are fixedly installed on the mounting block 210. The two positioning rods 24 are symmetrically arranged with the mounting block 210 as the center. The shape of the two positioning rods 24 is semi-cylindrical rod. The positioning rods 24 are arranged to be inserted into the positioning groove 25.

[0025] Furthermore, the surface of the mounting block 20 is provided with a slot 23, which is a square groove. The slot 23 is designed to receive the insertion of the plug block 28.

[0026] More specifically, the inner wall of the mounting box 22 is provided with positioning grooves 25. There are two positioning grooves 25, and the shape of the positioning grooves 25 is a semi-cylindrical groove. The positioning grooves 25 and the positioning rods 24 are provided to support the mounting block 20 and position it into the mounting box 22.

[0027] In general, the limiting block 27 is a square plate, and the cross-sectional dimensions of the limiting block 27 are adapted to the cross-sectional dimensions of the slide 26. The limiting block 27 is set to support the installation of the insert block 28.

[0028] Finally, a pull rod 21 is fixedly installed at the top of the limiting block 27. One end of the pull rod 21 passes through the surface of the mounting box 22. The pull rod 21 is used to drive the insertion block 28 to move. The cross-sectional shape of the insertion block 28 is a right triangle.

[0029] Working method: When it is necessary to disassemble the booking component body 4, pull the lever 21. The lever 21 drives the limit block 27 to slide linearly along the inner wall of the slide groove 26. When the limit block 27 slides linearly, it will drive the insertion block 28 to move until one end of the insertion block 28 leaves the slot 23. At this time, the fixing of the mounting block 210 can be released, and the mounting block 210 can be directly taken out from the mounting box 22 to disassemble the booking component body 4. When it is necessary to install, since the cross-sectional shape of the insertion block 28 is a right triangle, the mounting block 210 can be fixed by simply inserting it into the mounting box 22 through the positioning slot 25 and the positioning rod 24. The operation is simple and convenient, which is conducive to the replacement of the booking component body 4.

[0030] When the ordering component body 4 is not in use, the motor 33 can be started. The motor 33 drives the lead screw 35 to rotate. The lead screw 35 drives the slider 34 to slide linearly along the surface of the ordering component body 4. When the slider 34 slides, it will drive the limiting plate 32 to move linearly through the connecting rod 31. When the limiting plate 32 moves, it will close the anvil in the ordering component body 4 with the ordering, so as to avoid damage.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
