The embodiment provides a novel multifunctional blunt separating clamp which comprises a clamp rod 1, a clamp handle 2, a clamp head 3 and a traction rod 4, wherein the clamp handle 2 freely slides along the clamp rod 1, a locking piece 8 used for limiting the clamp handle 2 to a preset position of the clamp rod 1 is arranged on the clamp rod 1, the traction rod 4 is arranged at one end, far away from the clamp handle 2, of the clamp rod 1 in a sliding manner, and the clamp handle 2 is connected with the traction rod 4 through a steel wire in a traction manner; the tong head 3 comprises two tong flaps 301 hinged with the end part of the tong rod 1, and each tong flap 301 is hinged with the traction rod 4 through a connecting rod 302.
Specifically, the method comprises the following steps:
the forceps rod 1 comprises a guide section 101 and an extension section 102, a guide through groove 5 shaped like a Chinese character kou is arranged along the length direction of the guide section 101, and the forceps handle 2 is configured to be limited to slide in the guide through groove 5, so that the forceps handle 2 is ensured to move along the guide section 101. The finger ring sleeves 201 are integrally formed on the two sides of the forceps handle 2, so that when medical staff use the separating forceps, fingers extend into the finger ring sleeves 201, and the forceps handle 2 is conveniently pulled backwards to move.
A thread is provided on an outer wall of the guide section 101, and the locking member 8 is a locking nut that is screwed to the guide section 101.
Meanwhile, the extension section 102 is arranged at the front end of the guide section 101, and the hanging ring 7 is integrally formed at the rear end of the guide section 101, so that the whole separating clamp can be conveniently hung and placed through the hanging ring 7. A through hole is formed along the central axis of the extension section 102, and the traction rod 4 is inserted into the through hole and can freely move along the through hole.
Furthermore, a steel wire is arranged in the through hole, one end of the steel wire is fixedly connected with the traction rod 4, and the other end of the steel wire is fixedly connected with the forceps handle 2, so that the traction rod 4 can be driven to move by the steel wire through moving the forceps handle 2. One end of the traction rod 4, which is far away from the steel wire, is exposed out of the through hole, a transverse plate 6 is integrally formed at the end part of the traction rod 4, and a return spring 9 is sleeved on the traction rod 4 between the transverse plate 6 and the end part of the extension section 102.
The two clamp petals 301 are oppositely arranged, one end of each clamp petal 301 is rotatably hinged with the end of the extension section 102 through a pivot, the other end of each clamp petal is freely opened and closed, a connecting rod 302 is rotatably hinged on each clamp petal 301 through a pivot, one end of the connecting rod 302 far away from the clamp petals 301 is rotatably connected with the transverse plate 6 at the end of the traction rod 4 through a pivot, and then the two clamp petals 301, the two connecting rods 302 and the traction rod 4 form a reverse five-connecting-rod 302 mechanism.
As can be seen from the above, the present embodiment provides a novel multifunctional blunt separating forceps, which works according to the following principle:
the forceps handle 2 is pulled backwards, the forceps handle 2 pulls the traction rod 4 towards the through hole through the steel wire, the return spring 9 is compressed, then the traction rod 4 drives the connecting rod 302 hinged with the traction rod to move backwards, the connecting rod 302 moves backwards to slowly open the two forceps petals 301, and the purpose of stripping the tissues is achieved by utilizing the opening of the forceps petals 301. After the clamp flap 301 peels off the tissue, when the focus can be clearly exposed, the locking nut is rotated to abut against the clamp handle 2, so that the clamp handle 2 is prevented from retreating under the action of the return spring 9, the aim of maintaining the opening angle of the clamp flap 301 unchanged in the operation process is fulfilled, and favorable conditions are provided for the operation.
After the operation is finished, the locking nut is moved to be separated from the forceps handle 2, so that the return spring 9 is restored to the original length, the traction rod 4 is pulled out of the through hole, the connecting rod 302 moves forwards along with the traction rod 4, the connecting rod 302 is driven to move forwards, the two forceps petals 301 are closed, and the tissue is reset again.
Example 2
Referring to fig. 1 to 3, the present embodiment provides a novel multifunctional blunt separating forceps, which is substantially the same as embodiment 1, and mainly differs therefrom in that:
in this embodiment, the outer wall of the guide section 101 is provided with scale marks along the length direction of the extension section 102.
The purpose of the above design is:
because the opening angle of the forceps flap 301 is controlled by moving the forceps handle 2 through the through hole, and the moving distance of the forceps handle 2 cannot be accurately predicted under normal conditions, the medical staff usually controls the moving distance of the forceps handle 2 according to experience to control the opening angle of the forceps flap 301, and the opening angle of the forceps flap 301 cannot be accurately judged by such an adjusting mode.
Therefore, in this embodiment, scale marks are arranged on the outer wall of the guide section 101, and each scale mark corresponds to the opening angle of the forceps flap 301, so that the forceps handle 2 can be moved to the corresponding scale mark, and whether the forceps handle 2 is moved to the preset position can be clearly known, so that the opening degree of the forceps flap 301 in the operation process can be accurately controlled.
Example 3
Referring to fig. 1 to 3, the present embodiment provides a novel multifunctional blunt separating forceps, which is different from embodiment 1 or embodiment 2 mainly in that:
the outer edge surface of the forceps half 301 is provided with a plurality of blunt teeth 303.
The purpose of the above design is:
tissue fluid is usually present on the surface of the tissue, and the tissue is smooth. Therefore, when the jaw 301 is opened, the tissue is generally smooth, so that the tissue and the jaw 301 are likely to slip, and the jaw 301 is not likely to be opened.
Therefore, in the embodiment, the blunt teeth 303 are arranged on the outer edge surface of the forceps flap 301, so that the tissue can be conveniently held by the blunt teeth 303 in the opening process of the forceps flap 301, the tissue can be more conveniently opened, and the blunt teeth 303 can not injure the tissue.
To sum up, the utility model discloses following advantage or beneficial effect have at least:
by using the separating forceps, the forceps handle 2 is slid backwards, the steel wire between the forceps handle 2 and the traction rod 4 is utilized to pull the traction rod 4 backwards, so that the traction rod 4 drives the connecting rod 302 to open the forceps petals 301 at two sides with larger force, and the rigid separation of the forceps petals 301 to tissues is realized, thereby being beneficial to ensuring the quick stripping and safety of submucosal dissection (ESD), and particularly having unique advantages in the aspect of avoiding perforation and bleeding.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
