Abstract

An improved vascular clamp structure is comprised of a clip body and two clipping pieces, all of which constitute a vascular clamp used cooperatively for medical clamping pliers. The clip body is arranged with a bridge part, and from two ends of which a clipping part extends respectively and making one side of the clip body forming an opening; the clipping piece is arranged with a clipping body with a fitting slot. The fitting slot and the clipping part can be assembled together. Both adjacent faces of the clipping bodies are respectively arranged with a groove and at least one male or female fastener inter-buckled together. Wherein, the clip body is set as a memory metal. By arranging clipping pieces, the vascular clamp of the present invention enhances the frictional areas of inter-contact. Arranging male and female fasteners at the adjacent faces of clipping pieces also enhances the clipping force, and effectively improves the slipping drawback of traditional vascular clamp. In addition, the vascular clamp is made of memory metal; by the separation of male and female fasteners, the vascular clamp further possesses the function of dismantlement.

Claims

1. An improved vascular clamp structure, comprising:

a clip body, arranged with a bridge part with an inflecting point, and extending a first clipping part and a second clipping part respectively from two ends of the bridge part, and making one side of the clip body forming an opening for fitting a vessel;

a first clipping piece, arranged with a first clipping body with a first fitting slot and assembled fixedly by the first fitting slot and the first clipping part of the clip body, and the first clipping body being arranged with a first groove and at least one male fastener at a face adjacent to a second clamping piece; and

a second clipping pieces, arranged with a second clipping body with a second fitting slot and assembled fixedly by the second fitting slot and the second clipping part of the clip body, and the second clipping body being arranged with a second groove and at least one female fastener matching the male fastener at another face adjacent to the first clipping piece.

2. The improved vascular clamp structure according to claim 1, wherein the clip body is set as a memory metal with the effectiveness of restoration.

3. The improved vascular clamp structure according to claim 1, wherein the first clipping part, the second clipping part, the first fitting slot and the second fitting slot are configured as wedged dovetails assembled and matching to each other.

4. The improved vascular clamp structure according to claim 3, wherein the wedged dovetails are to set the inside faces of the first fitting slot and the second fitting slot as two oblique walls and set the outside faces of the first clipping part and the second clipping part as two bevel edges corresponding to each other, and wherein bottom sides of two oblique walls are additionally arranged as a ring-guiding slot respectively to be inter-wedged fixedly with a pair of corresponding guiding rails arranged at corresponding bottom sides of two bevel edges.

5. The improved vascular clamp structure according to claim 1, wherein the first groove is set as a convex wedge block projected from the surface of the first clipping body, while the second groove is set as a concave wedge slot recessed in a surface of the second clipping body, and wherein the convex wedge block is arranged as corresponding to the configuration of the concave wedge slot.

6. The improved vascular clamp structure according to claim 5, wherein the convex wedge block is arranged with a plurality of longitudinal ribs interspaced separately, and between the longitudinal ribs, a plurality of oblique ribs are arranged as being interspaced with the longitudinal ribs, and the concave wedge slots are arranged with a plurality of longitudinal slots corresponding to the longitudinal ribs and a plurality of oblique slots corresponding to the oblique ribs.

7. The improved vascular clamp structure according to claim 1, wherein the first groove is comprised of a plurality of flat cone convex patterns projected from the surface of the first clipping body and adjacently interspaced, while the second groove is also comprised of a plurality of flat cone convex patterns projected from the surface of the second clipping body and adjacently interspaced.

8. The improved vascular clamp structure according to claim 1, wherein the male fastener is a diverging insetting piece, while the female fastener is an insetting hole with a converging structure therein.

9. The improved vascular clamp structure according to claim 8, wherein the insetting piece is comprised of two insetting ribs extending and diverging outward to a connecting side of the clipping body, and an elastic space is formed between the insetting ribs, while the converging structure is configured by forming a projection block respectively at two sides of the opening of the insetting hole, and a wedge block is formed at a center of the converging structure, making two sides of the wedge block respectively forming two holes capable of being inserted by the insetting rib.

10. The improved vascular clamp structure according to claim 8, wherein the male fastener is arranged at a center of the bottom part of the first clipping body of the first clipping piece, while the female fastener is arranged at a center of the bottom part of the second clipping body of the second clipping piece.
