Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a pair of special curved forceps for hemorrhoid surgery. Background Art

[0002] Curved forceps are an auxiliary tool for hemorrhoid surgery. In the mixed hemorrhoid external stripping and internal ligation, curved forceps are used to clamp internal hemorrhoids, and then ligated with silk thread. For example, the Chinese patent with patent publication number CN219461273U proposes a hemorrhoid surgery instrument assembly, which includes two left and right forceps, the left forceps includes a control line ring, a first forceps head, a first pin hole, a first forceps handle, and a first finger ring in sequence, and the right forceps includes a second forceps head, a second pin hole, a second forceps handle, and a second finger ring in sequence, and the first forceps head and the second forceps head are arc-shaped and bent in the vertical direction of the plane where the first finger ring and the second finger ring are located. However, in the actual operation process, since the first forceps handle and the second forceps handle are straight, it is not conducive to the doctor to perform ligation and visual field observation, and when clamping internal hemorrhoids, the connection between the first forceps head and the first forceps handle and the connection between the second forceps head and the second forceps handle are easy to clamp the tissue around the internal hemorrhoids, such as the anal sphincter, causing postoperative pain.

[0003] Therefore, it is necessary to propose a special curved forceps for hemorrhoid surgery, which can effectively avoid pain caused by clamping tissues other than internal hemorrhoids and facilitate the doctor's operation. Utility Model Content

Figure 2 and Figure 3The first curved portion 3 is bent upward from the back to the front relative to the clamp body 5, and the two ends of the second curved portion 4 are respectively connected to the first curved portion 3 and the clamp body 5. The second curved portion 4 is an arched structure with a convex middle portion, and the lower side of the second curved portion 4 forms a downwardly open concession portion between the first curved portion 3 and the clamp body 5, which can effectively avoid clamping the internal anal sphincter when clamping internal hemorrhoids during surgery, reduce the patient's postoperative anal pain, and reduce the operation of re-clamping the internal hemorrhoids due to mis-clamping the internal anal sphincter during surgery, saving the doctor's operation time; because the bending directions of the second curved portion 4 and the first curved portion 3 are opposite, the second curved portion 4 and the first curved portion 3 are provided with a curved smooth transition portion 7 on the lower side surface of the connection position to avoid unnecessary damage to the patient caused by the connection position of the second curved portion 4 and the first curved portion 3; the clamp body 5 of the first clamp body 1 and the clamp body 5 of the second clamp body 2 are hinged by a pin shaft, and the first clamp body 1 and the second clamp body 2 face each other as the occlusal surface. Specifically, refer to Figure 3 The occlusal surface 31 of the first curved portion is provided with anti-slip teeth, which directly contacts the internal hemorrhoids when clamping them during surgery, can effectively prevent slippage, and has a good fixation effect. The occlusal surface 41 of the second curved portion is a smooth surface, which is not easy to clamp tissues and avoids accidental clamping of the internal anal sphincter.

[0027] In a specific embodiment, reference Figure 2 The second curved portion 4 is provided with a curved vertex, the first curved portion 3 is provided with an upper end point, the distance A between the curved vertex and the upper side surface of the forceps body 5 is in the range of 3mm to 5mm, and the curved vertex is lower than the upper end point, which can avoid the mis-clamping of the internal anal sphincter during the external stripping and internal ligation of mixed hemorrhoids, and will not make the protrusion of the second curved portion 4 hinder the surgical operation or injure other tissues of the patient's body; the horizontal distance B between the two ends of the second curved portion 4 is in the range of 3mm to 9mm, which is convenient for observing the situation of clamping the internal hemorrhoids and providing a better field of vision for the doctor to perform the surgical operation; the angle α between the straight line where the two ends of the first curved portion 3 are located and the lower side surface of the forceps body 5 is in the range of 15° to 45°, which is convenient for the doctor to perform the surgical operation.

[0028] In a specific embodiment, reference Figure 1 , Figure 4 and Figure 5 , also includes a first clamping portion 11 and a second clamping portion 21. The first clamping portion 11 is fixedly arranged on the clamp body 5 of the first clamp body 1, and the second clamping portion 21 is fixedly arranged on the clamp body 5 of the second clamp body 2. The lower side surface of the first clamping portion 11 and the upper side surface of the second clamping portion 21 are engaged with each other; specifically, the lower side surface of the first clamping portion 11 and the upper side surface of the second clamping portion 21 are provided with obliquely arranged positioning teeth, and the first clamping portion 11 and the second clamping portion 21 are engaged to fix the clamping state, which is more labor-saving during operation.

[0029] In a specific embodiment, the first curved portion 3 and the second curved portion 4 are both matte metal parts, which can avoid reflection, thereby reducing the stimulation of the light source to the doctor's eyes during the operation and will not affect the implementation of the operation.

[0030] In the external stripping and internal ligation of mixed hemorrhoids, the special curved forceps for hemorrhoid surgery proposed by the utility model are used, the first curved part 3 clamps the internal hemorrhoids, and the anti-slip teeth of the occlusal surface 31 of the first curved part directly contact the internal hemorrhoids, which can effectively prevent slippage and has a good fixing effect. Since the second curved part 4 is an arched structure with an upward convex middle part, a downward open concession part between the first curved part 3 and the forceps body 5 is formed to avoid accidental clamping of the internal anal sphincter. Moreover, due to the design of the first curved part 3 and the second curved part 4, when the doctor uses the curved forceps to clamp the internal hemorrhoids, the concession part also provides a better surgical field of view, which is convenient for the doctor to observe the situation of clamping the internal hemorrhoids; further, since the occlusal surface 41 of the second curved part is a smooth surface, it is not easy to clamp tissues, thereby avoiding accidental clamping of the internal anal sphincter; the first clamping part 11 and the second clamping part 21 can also be clamped to fix the clamping state, and the operation is labor-saving. Therefore, the use of the special curved forceps for hemorrhoid surgery proposed by the utility model solves the problem that the internal anal sphincter is easily clamped when clamping internal hemorrhoids during surgery, reduces the operation of re-clamping the internal hemorrhoids due to mis-clamping the internal anal sphincter during surgery, and saves the doctor's operation time.
