Abstract

The utility model discloses a matching structure for a nail bin and nail pushing pieces of an anastomat, which comprises a nail bin, a plurality of nail pushing pieces and a cover plate; the nail pushing pieces are positioned in the nail bin; the cover plate is covered on the nail bin; a plurality of nail pushing piece holes are formed on the nail bin; the ends of the nail pushing pieces can extend out of the nail pushing piece holes of the nail bin; each nail pushing piece comprises a first guide surface, a second guide surface, a first contact surface and a second contact surface; both the first contact surface and the second contact surface adopt convex cambered surfaces; both ends of the first guide surface are connected with the first contact surface and the second contact surface respectively through a first concave arc-shaped junction surface; both ends of the second guide surfaces are connected with the first contact surface and the second contact surface respectively through a second concave arc-shaped junction surface; and both the first contact surface and the second contact surface are in contact with the inner walls of the nail pushing piece holes of the nail bin respectively. The matching structure reduces the resistance in the process of pushing the nail pushing pieces out and is labor-saving during the impact.

Description

The nail bin of anastomat and the fit structure of pushing slice of nail

Technical field

This utility model relates to a kind of nail bin of anastomat and the fit structure of pushing slice of nail.

Background technology

At present, in the nail bin of medical anastomat pushing slice of nail is housed, under the effect of push rod, pushing slice of nail need stretch out the ejector pin film perforation of nail bin, is used for pulling the trigger and identical wound; The surface of the pushing slice of nail of traditional anastomat all contacts with the ejector pin film perforation of nail bin, first spigot surface, second spigot surface, four faces of first contact surface and second contact surface of being pushing slice of nail all contact with the inwall of ejector pin film perforation, this structure interface is long-pending big, friction also just increases, be used for promoting the just increase of power of push rod simultaneously, the power of percussion just increases.

Summary of the invention

The purpose of this utility model is to provide a kind of nail bin of labour-saving anastomat and fit structure of pushing slice of nail of pulling the trigger.

In order to achieve the above object, the technical solution of the utility model is: a kind of nail bin of anastomat and the fit structure of pushing slice of nail, comprise nail bin, several pushing slice of nail and cover plate, several pushing slice of nail are positioned at nail bin, the cover plate lid is put on nail bin, have several ejector pin film perforations on the nail bin, the end of pushing slice of nail can be stretched out outside the ejector pin film perforation of nail bin, pushing slice of nail has first spigot surface, second spigot surface, first contact surface and second contact surface, first contact surface and second contact surface are outer convex globoidal, the two ends of first spigot surface are connected with second contact surface with first contact surface by the first indent arc joint face respectively, the two ends of second spigot surface are connected with second contact surface with first contact surface by the second indent arc joint face respectively, and first contact surface and second contact surface all contact with the inwall of the ejector pin film perforation of nail bin.

The tail end of described nail bin has push-rod hole.

After adopting said structure, because the first spigot surface two ends all are connected with second contact surface with first contact surface respectively by the first arc joint face, the second spigot surface two ends all are connected with second contact surface with first contact surface respectively by the second arc joint face, therefore reduced the contact area of the ejector pin film perforation of pushing slice of nail and nail bin, have only first contact surface to contact with the inwall of second contact surface with the ejector pin film perforation of nail bin, therefore reduced the resistance of releasing pushing slice of nail, laborsaving during percussion.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail this utility model.

Referring to Fig. 1,2,3, shown in 4, a kind of nail bin of anastomat and the fit structure of pushing slice of nail, comprise nail bin 1, several pushing slice of nail 2 and cover plate 3, several pushing slice of nail 2 are positioned at nail bin 1, cover plate 3 lids are put on nail bin 1, has several ejector pin film perforations 1-1 on the nail bin 1, the end of pushing slice of nail 2 can be stretched out outside the ejector pin film perforation 1-1 of nail bin 1, pushing slice of nail 2 has the first spigot surface 2-1, the second spigot surface 2-2, the first contact surface 2-3 and the second contact surface 2-4, the first contact surface 2-3 and the second contact surface 2-4 are outer convex globoidal, the two ends of the first spigot surface 2-1 are connected with the second contact surface 2-4 with the first contact surface 2-3 by the first indent arc joint face 4 respectively, the two ends of the second spigot surface 2-2 are connected with the second contact surface 2-4 with the first contact surface 2-3 by the second indent arc joint face 4 ' respectively, and the first contact surface 2-3 and the second contact surface 2-4 all contact with the inwall of the ejector pin film perforation 1-1 of nail bin 1.

Shown in Fig. 1,2, push rod is installed for convenience, the tail end of described nail bin 1 has push-rod hole 1-2.

Shown in Fig. 1,2, when this utility model uses, several pushing slice of nail 2 are contained in the nail bin 1, and cover with cover plate 3, the front portion of pushing slice of nail 2 can be stretched out under the effect of push rod outside the ejector pin film perforation 1-1 of nail bin 1.
