The specific implementation mode is as follows:
the invention is further illustrated with reference to the following figures and examples.
Example 1: the first clinical internal medicine vascular forceps, as shown in fig. 1-6, include two inner forceps mouths, i.e. a forceps mouth 1 and a forceps mouth 2, and a hemostatic cotton slot 14 is provided in the middle of the inner side of each inner forceps mouth. And the two forceps arms are respectively connected with the two inner forceps mouths, namely a forceps arm I4 and a forceps arm II 5. The front ends of the two forceps arms are hinged together through a hinge shaft 3, and the tail ends of the two forceps arms are respectively provided with a finger ring 13. The tail ends of the two forceps arms are respectively provided with a shaping frame 12, and the opposite surfaces of the two shaping frames 12 are provided with a saw-toothed convex-concave clamping structure, so that the two shaping frames 12 can be clamped together after being combined and overlapped. The above structural parts are commonly found in the existing vascular clamps, or other auxiliary parts are added on the basis of the existing vascular clamps.
On the basis of the structural characteristics, the outer sides of the two forceps arms are respectively fixed with an outer forceps handle, and the tail end of each outer forceps handle is respectively provided with an outer forceps mouth.
The outer jaw and the outer handle in fig. 1-4 form an arc-shaped or fold-line-shaped integrated structure. The integrated structure is fixed with the outer side of the forceps arm. The fixing mode of fig. 1 and 2 is that a fixing clamping groove is respectively arranged between the outer forceps handle and the forceps arm, and a clamp 11 is sleeved in the two corresponding fixing clamping grooves 10, so that the outer forceps handle and the forceps arm are fixed together. The fixed clamping groove is preferably internally provided with a saw-toothed convex-concave structure, and the inner side surface of the clamp is also provided with a saw-toothed convex-concave structure so as to achieve the effect of stable fixation.
