Description

Technical Field

[0001] The utility model relates to the technical field of cutting staplers, in particular to a high-precision clamping hook of a surgical linear cutting stapler. Background Art

[0002] A cutting stapler is a mechanical device that integrates cutting and suturing functions. It can accurately and efficiently cut workpieces or tissues in different work links, and then perform staplers or suturing. Depending on the application field and specific functions, cutting staplers can be divided into many types, such as cutting staplers for metal processing, cutting staplers for plastic processing, cutting staplers for textile processing, cutting staplers for medical use, etc.

[0003] The clamping hook of the surgical linear cutting stapler is an important component of the surgical linear cutting stapler. It is mainly responsible for clamping the staple cartridge assembly and the anvil assembly during surgery and ensuring that the staples can be correctly bent and formed, thereby completing tissue cutting and suturing. However, the existing clamping hook is not convenient for adjusting the clamping degree of the staple cartridge assembly and the anvil assembly, which can easily cause insufficient clamping force to cause poor bending and forming of the staples, or cause tissue damage due to excessive clamping force. Utility Model Content

[0007] Furthermore, a column is fixedly installed on the inner wall of the ring, and the column is cylindrical in shape.

[0008] Furthermore, a mounting plate is fixedly mounted on the top of the column, and the mounting plate is in the shape of a square plate.

[0009] Furthermore, the mounting plate is rotatably connected to a screw rod through a bearing, a motor is fixedly mounted on the inner wall of the ring, the rotating shaft end of the motor is fixedly connected to the screw rod, a slider is threadedly connected to the screw rod, and the slider is in the shape of a square block.

[0010] Furthermore, a track is fixedly mounted on the slider, and the track is in the shape of a square frame.

[0011] Furthermore, a sliding rod is slidably provided on the inner wall of the track, and one end of the sliding rod is fixedly connected to the nail magazine frame.

[0012] Furthermore, a limiting rod is fixedly installed between the mounting plate and the circular ring. The limiting rod is in the shape of a cylindrical rod. The slider slides on the limiting rod. There are two limiting rods.

[0013] The high-precision clamping hook of the surgical linear cutting stapler proposed in the present invention has the beneficial effect that: by providing a clamping hook assembly, the present invention can ensure that the clamping force between the staple magazine assembly and the staple anvil assembly can be stably adjusted during the operation, thereby avoiding poor bending and forming of the staples due to insufficient clamping force, or tissue damage due to excessive clamping force.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-4, a high-precision clamping hook of a surgical linear cutting stapler includes a stapler frame 1 and a staple anvil frame 4, and is characterized in that: a clamping hook assembly is installed on the stapler frame 4, and by providing the clamping hook assembly, it can be ensured that during the operation, the clamping force between the stapler frame assembly and the staple anvil assembly can be stably adjusted, thereby avoiding poor bending and forming of the staples due to insufficient clamping force, or tissue damage due to excessive clamping force. A protective sleeve 3 is threadedly connected to the clamping hook assembly, and the clamping hook assembly includes a ring 21, which is fixedly mounted on the stapler frame 4, and is provided with a thread. The protective sleeve 3 is threadedly connected to the ring 21. The protective sleeve 3 is provided to prevent the clamping hook from clamping the tissue to be stapled during the operation, thereby ensuring the safety of the surgical operation.

[0021] In detail, a column 24 is fixedly installed on the inner wall of the ring 21. The column 24 is cylindrical in shape. The column 24 is provided to facilitate the installation of the mounting plate 22. A mounting plate 22 is fixedly installed on the top of the column 24. The mounting plate 22 is square in shape. The mounting plate 22 is provided to facilitate the rotation of the screw rod 29.

[0022] Furthermore, a screw rod 29 is rotatably connected to the mounting plate 22 through a bearing. The screw rod 29 is provided to facilitate the slider 25 to move linearly along the surface of the limit rod 23. A motor 28 is fixedly installed on the inner wall of the ring 21. The motor 28 has forward and reverse rotation functions. The motor 28 is provided to facilitate the screw rod 29 to rotate. The shaft end of the motor 28 is fixedly connected to the screw rod 29. The slider 25 is threadedly connected to the screw rod 29. The slider 25 is in the shape of a square block. The setting of the slider 25 facilitates the installation of the track 26. When the position of the slider 25 needs to be adjusted, the motor 28 is started, and the motor 28 drives the screw rod 29 to rotate. The screw rod 29 drives the slider 25 to slide linearly along the surface of the limit rod 23 until the slider 25 moves to a suitable position.

[0023] In more detail, a track 26 is fixedly installed on the slider 25, and the shape of the track 26 is a square frame. The setting of the track 26 is convenient for accommodating the sliding of the slide rod 27. The inner wall of the track 26 is slidingly provided with a slide rod 27. One end of the slide rod 27 is fixedly connected to the nail magazine rack 1. The shape of the slide rod 27 is a cylindrical rod. When the slider 25 moves, the slide rod 27 will be driven to move through the track 26.

[0024] Finally, a limiting rod 23 is fixedly installed between the mounting plate 22 and the ring 21. The limiting rod 23 is in the shape of a cylindrical rod. The slider 25 slides on the limiting rod 23. There are two limiting rods 23. The setting of the limiting rod 23 serves the purpose of limiting the movement of the slider 25.

[0025] Working method: During the operation, when it is necessary to adjust the clamping force between the nail magazine rack 1 and the nail anvil rack 4, the motor 28 is started, and the motor 28 drives the screw rod 29 to rotate, and the screw rod 29 drives the slider 25 to slide linearly along the surface of the limit rod 23. When the slider 25 slides, it will drive the track 26 to move linearly. When the track 26 moves, it will drive the nail magazine rack 1 to expand through the slide rod 27, thereby achieving the purpose of adjusting the clamping force between the nail magazine rack 1 and the nail anvil rack 4, avoiding poor bending and forming of the anastomosis staples due to insufficient clamping force, or tissue damage due to excessive clamping force.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
