DETAILED DESCRIPTION

[0021] 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.

[0022] Reference Figure 1-5 An angle-adjustable stapler includes a stapler body 1, an adjustment seat 2 is provided at one end of the stapler body 1, an adjustment button 4 is rotatably mounted on the upper portion of the adjustment seat 2, and a connecting seat 3 is rotatably mounted in the middle portion of the adjustment seat 2, one end of the connecting seat 3 is connected to a handle 102, and a trigger handle mechanism 103 is provided at the bottom of the handle 102;

[0023] Furthermore, a first locking groove 31 and a second locking groove 32 are respectively provided on both sides of one end of the connecting seat 3, and a plurality of limiting grooves 311 are provided on one side of the inner wall of the first locking groove 31, and an adjustment button 4 is installed in the first locking groove 31 and the second locking groove 32 for limiting movement.

[0024] One end of the stapler body 1 is provided with a stapler head 101 .

[0025] In addition, a slot is provided on the upper portion of the adjustment seat 2, in which an adjustment button 4 is rotatably installed, a sliding slot is provided on the upper portion of the adjustment button 4, in which a sliding block 41 is installed for limited sliding in the sliding slot, and a fixed block 5 is fixedly installed at the bottom of the adjustment button 4, and a sliding slot corresponding to the adjustment button 4 is provided on the fixed block 5, and a locking block 411 is installed for limited movement in the sliding slot.

[0026] Furthermore, one end of the locking block 411 is fixedly connected to the sliding block 41 , and the locking block 411 is installed in a sliding groove provided at the bottom of the fixed block 5 for limited movement.

[0027] Furthermore, the locking block 411 and the fixing block 5 are respectively snap-fitted into the first locking groove 31 and the second locking groove 32, and are in frictional contact with the inner walls of the grooves. A protrusion is provided on one side of the locking block 411, and the protrusion fits into the limiting groove 311 in the first locking groove 31. The provision of the first locking groove 31 and the second locking groove 32 can effectively limit the locking block 411 and the fixing block 5.

[0028] Furthermore, rotating columns 6 are provided on both sides of the connecting seat 3 , and the rotating columns 6 are rotatably installed on both sides of the inner wall of the adjusting seat 2 .

[0029] In this embodiment, by depressing the adjustment button 4, the locking block 411 and the fixing block 5 at the bottom of the adjustment button 4 are limitedly engaged in the first locking groove 31 and the second locking groove 32 in the connecting seat 3, and are in friction contact with the inner wall of the groove, providing a certain rotation damping force. At the same time, the angle is adjusted by rotating the handle 102 and the anastomosis device body 1. When the handle 102 is rotated, the connecting seat 3 is rotated in the adjustment seat 2 through the rotating column 6. The first locking groove 31 and the second locking groove 32 in the connecting seat 3 rub against the fixing block 5 and the locking block 411 in the adjustment button 4. When it is adjusted to a suitable angle, the sliding block 41 on the adjustment button 4 is toggled, and the sliding block 41 drives the locking block 411 connected to the bottom to move. At this time, the locking block 411 moves in the first locking groove 31, and a protrusion different from the fixed block 5 is provided on one side of the locking block 411. Therefore, the locking block 411 is engaged with the limiting groove 311 in the first locking groove 31 through the protrusion, and the entire connecting seat 3 is locked and limited, thereby completing the angle adjustment operation. At this time, the suturing operation of the anastomosis device body 1 is completed by triggering the handle mechanism 103.

[0030] It is worth noting that the inner walls of the first locking groove 31 and the second locking groove 32 are provided with concave-convex textures to increase the friction coefficient with the fixing block 5 and the locking block 411 .

[0031] It is worth noting that the detailed anastomosis operation contents not described above are common technical knowledge known to those skilled in the art, and therefore will not be elaborated on in detail.

[0032] In the present invention, the holding angle of the stapler body 1 can be adjusted by setting the adjustment seat 2 and the connecting seat 3, which is more in line with the operator's habit of exerting force. At the same time, the locking block 411 and the fixing block 5 are in friction contact with the locking groove in a natural state, thereby ensuring that it will not be too loose when adjusting the angle. At the same time, the sliding block 41 can be moved to engage and lock the locking block 411 with the limiting groove 311, thereby clamping the handle 102 and completing the angle adjustment. Compared with the traditional straight-tube fixed stapler, this device has the effect of quickly adjusting the angle and is more in line with the human body's force, effectively improving the operating efficiency and accuracy.

[0033] 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.
