The arc-shaped pieces 30 with openings facing each other facilitate the expansion of the surgical area to provide physical space convenience for the surgery, ensure a wide surgical field of view and exposure of the surgical site, and facilitate the smooth progress of the surgery; the arrangement of the arc-shaped rack 40 and the locking portion 50 facilitates fixing the distance between the first clamp body 10 and the second clamp body 20 after opening and closing, thereby reducing the workload of medical staff.
[0030] Specifically, the arc-shaped rack 40 is fixed on the inner side of the other end of the first pliers body 10 , and the arc-shaped rack 40 passes through the fixing hole 201 . The locking portion 50 is disposed below the fixing hole 201 , and the protrusion 501 is disposed at the top of the locking portion 50 and meshes with the serrations at the bottom of the arc-shaped rack 40 .
[0031] The locking portion 50 and the sliding portion 502 are in the shape of the number "7" as a whole. The sliding portion 502 is arranged at the bottom of the locking portion 50, the elastic portion 2031 abuts against the bottom of the sliding portion 502, and the two sides of the sliding portion 502 abut against the side walls on both sides of the sliding groove 203, and a part of the sliding portion 502 is slidably connected to the sliding groove 203.
[0032] When the locking part 50 is pressed down, the sliding part 502 slides down to exert a downward force on the elastic part 2031, i.e., the spring, and the convex part 501 on the locking part 50 is away from the saw teeth of the arc-shaped rack 40 and no longer meshes; when the locking part 50 is stopped from being pressed down, the sliding part 502 returns to its original position due to the elastic force of the spring, and the convex part 501 on the locking part 50 is meshed with the saw teeth of the arc-shaped rack 40 again. The fixing hole 201 is connected to the accommodating cavity 202.
[0033] In this embodiment, the arc-shaped piece 30 is detachably connected to one end of the first clamp body 10 and the second clamp body 20. During the operation, the arc-shaped piece 30 of appropriate size can be selected for use according to the actual situation, which is practical and does not require the preparation of multiple expansion forceps with different sizes of arc-shaped pieces 30. The detachable connection method refers to the commonly used technical means in the prior art, such as buckle connection, sleeve setting, magnetic attraction, etc., which will not be repeated here.
[0034] In this embodiment, the arc length of the arc piece 30 is 6-12 mm, the diameter of the arc piece 30 is 15-25 mm, and the height of the arc piece 30 is 20-30 mm. Specifically, the arc length of the arc piece 30 is 8 mm, the diameter of the arc piece 30 is 20 mm, and the height of the arc piece 30 is 25 mm.
[0035] In this embodiment, a first protective layer (not shown in the figure) is provided on the surface of the arc-shaped sheet 30, and the first protective layer is provided to wrap the sharp part of the arc-shaped sheet 30 to improve safety. Furthermore, in this embodiment, a plurality of first anti-slip stripes (not shown in the figure) are provided on the outer surface of the first protective layer, so that the outer surface of the arc-shaped sheet 30 can better contact the periphery of the lesion in the patient's body.
[0036] In this embodiment, the locking portion 50 is provided with a pressing portion 503. The pressing portion 503 is provided to facilitate applying a downward pressure force to the locking portion 50. Specifically, the pressing portion 503 is provided at one end of the locking portion 50, and the pressing portion 503 is located outside the accommodating cavity 202.
[0037] In this embodiment, the saw teeth of the arc-shaped rack 40 are inclined toward one side, and the protrusion 501 is adapted to the saw teeth. The saw teeth of the arc-shaped rack 40 can generally be ordinary upward saw teeth. Before opening and closing the expansion pliers, the pressing part 503 is pressed first to make the protrusion 501 on the locking part 50 away from the saw teeth of the arc-shaped rack 40 and no longer meshed. Then, the distance between the arc-shaped pieces of the first pliers body 10 and the second pliers body 20 is adjusted by moving the other end of the first pliers body 10 and the second pliers body 20. After adjustment, the locking part 50 is stopped from being pressed down, and the protrusion 501 on the locking part 50 is meshed with the saw teeth of the arc-shaped rack 40 again. However, in this embodiment, the saw teeth of the arc-shaped rack 40 are inclined toward the left side, and the protrusion 501 is inclined toward the right side. When manually trying to move the arc-shaped rack 40 to the left, the saw teeth of the arc-shaped rack 40 are held by the protrusion 501 and cannot move. At this time, the pressing part 503 needs to be pressed first; but when the second pliers 20 does not move, the first pliers 10 is manually moved to the right, so that the arc-shaped rack 40 moves to the right, and the saw teeth of the arc-shaped rack 40 slide over the protrusion 501 along the force of moving to the right. Therefore, there is no need to press the pressing part 503, and the first pliers 10 can be directly moved to the right to increase the distance between it and the arc-shaped piece 30 of the second pliers 20, so that the expansion pliers are opened. Compared with ordinary non-inclined sawtooth, the saw teeth inclined to one side need to press the pressing part 503 when moving the arc-shaped rack 40 to the left, but it does not need to be pressed when moving the arc-shaped rack 40 to the right, which improves convenience.
[0038] In this embodiment, a gripping portion 60 is further provided at the other end of the first pliers body 10 and the second pliers body 20, and the inner circle of the gripping portion 60 is provided with a second protective layer (not shown in the figure). The second protective layer can protect the fingers of medical staff from being worn and injured when holding the device for a long time; a plurality of second anti-slip stripes (not shown in the figure) are provided on the surface of the second protective layer, so that the medical staff will not slip easily when holding the device.
[0039] The utility model provides a surgical expansion forceps, and its working principle is as follows:
[0040] Open the surgical expansion forceps: the second forceps body 20 does not move, and the first forceps body 10 is manually moved to the right, so that the arc-shaped rack 40 fixed on the first forceps body 10 moves to the right accordingly, and the distance between the first forceps body 10 and the other end of the second forceps body 20 becomes smaller, and the distance between the arc-shaped pieces 30 at one end of the first forceps body 10 and the second forceps body 20 becomes larger; when the distance between the arc-shaped pieces 30 meets the requirements, stop moving the first forceps body 10.
[0041] Closed surgical expansion forceps: the second forceps body 20 does not move, first press down the pressing part 503, and then manually move the first forceps body 10 to the left, so that the arc-shaped rack 40 fixed on the first forceps body 10 moves to the left accordingly, and the distance between the first forceps body 10 and the other end of the second forceps body 20 becomes larger, and the distance between the arc-shaped pieces 30 of the first forceps body 10 and the second forceps body 20 becomes smaller; when the distance between the arc-shaped pieces 30 meets the requirements, stop moving the first forceps body 10, and stop pressing down the pressing part 503, so that the protrusion 501 on the locking part 50 is re-engaged with the serrations of the arc-shaped rack 40 and locked.
[0042] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and they cannot be used to limit the protection scope of the utility model.
