Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
It should be noted that, in the description of the present invention, the terms "front", "rear", "left", "right", "upper", "lower", "inner", "outer", etc. indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for convenience of description of the present invention but do not require the present invention to be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention. As used in the description of the present invention, the terms "front," "back," "left," "right," "up," "down" and "in" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
The utility model discloses specific embodiment provides a slide formula lymph gland pincers are used in operation, as shown in fig. 1, is the utility model discloses the schematic structure of embodiment, lymph gland pincers include pincers body 1, be located the slide 2 of pincers body 1 side, slide 2 is equipped with spacing key 7 along pincers 1 axial rather than sliding connection of body, between slide 2 and the pincers body 1, by corresponding guide way and guide block each other component, play axial direction and radial spacing effect.
The rear end of the clamp body 1 is fixedly connected with a first clamp handle 3 which are integrally formed; the front end of the sliding plate 2 is fixedly connected with a second binding clip 6 which are integrally formed. The rear end of the pliers body 1 is hinged with a second pliers handle 4 matched with the first pliers handle 3 through a first rotating shaft 31, the front end of the pliers body 1 is hinged with a first pliers head 5 matched with a second pliers head 6 through a second rotating shaft 51, and the first pliers head 5 is hinged with the front end of the sliding plate 2 through a third rotating shaft 61. The front end of the second clamp handle 4 is in transmission connection with the rear end of the sliding plate 2, and when the second clamp handle 4 is opened, the sliding plate 2 can be driven to slide towards the left side relative to the clamp body 1; when the second clamp handle 4 is closed, the sliding plate 2 can be driven to slide towards the right side relative to the clamp body 1.
The utility model discloses lymph gland pincers's theory of operation does: the second forceps handle 4 is opened clockwise, the front end of the second forceps handle 4 pushes the rear end of the sliding plate 2 to enable the sliding plate to slide leftwards, the sliding plate 2 drives the third rotating shaft 61 to deflect leftwards, and the first forceps head 5 is driven to deflect clockwise under the action of relative displacement between the second rotating shaft 51 and the third rotating shaft 61 due to the fact that the second rotating shaft 51 is relatively static at the moment, and the forceps heads of the lymph node forceps are opened. The second forceps handle 4 is closed anticlockwise, the rear end of the sliding plate 2 is pulled by the front end of the second forceps handle 4 to enable the sliding plate to slide towards the right side, the sliding plate 2 drives the third rotating shaft 61 to deflect rightwards, and the first forceps head 5 is driven to deflect anticlockwise under the action of relative displacement between the second rotating shaft 51 and the third rotating shaft 61 until the forceps heads of the lymph node forceps are closed. When the binding clip is opened, because the utility model discloses body 1 and slide 2 of lymph gland pincers middle section position are axial relative slip, and do not take place radial expansion, therefore are applicable to the nimble use under the little wound operation condition.
More specifically, the inboard of first binding clip 5 and second binding clip 6 all is equipped with the annular sawtooth 8 that meshes each other, specifically as shown in fig. 2, is in the embodiment of the utility model discloses the schematic structure of annular sawtooth is shown, and in the figure, the top figure is the foresight of first binding clip 5 and second binding clip 6, and the figure of below is the inboard view of second binding clip 6, can see, and this annular sawtooth 8 is surrounded by a plurality of sawtooth and forms, when applying not equidirectional pulling force, the homoenergetic effectively strengthens the power of grabbing when snatching human tissue, effectively avoids the landing.
As a preferred scheme, the first forceps handle 3 and the second forceps handle 4 are both composed of a handle rod and an annular handle, and the annular handle is fixedly connected or hinged with the forceps body 1 through the handle rod, so that an operator can conveniently pass fingers through the annular handle to perform surgical operation; meanwhile, the locking teeth 41 are arranged on the inner sides of the first forceps handle 3 and the second forceps handle 4, and the effect of relative limiting when the handles are closed is achieved
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
