Description

Tray packaging clamp for surgical suture

Technical Field

The invention relates to the field of packaging boxes, in particular to a tray packaging card for surgical suture lines.

Background

The function of the surgical suture and the needle package is to protect the needle and suture during storage, shipping and storage. In addition, it facilitates smooth release of the needle and suture with minimal application of force during application.

There are two general types of packages currently used for surgical sutures, with or without needles, one being paper folder packaging cards, folding and dividing medical grade cardboard into a plurality of panels in a specific configuration, then wrapping the suture around the panels, and then locking the panels in place using slits and locking tabs cut into the panels to complete the package; the other is an oval tray packaging card with winding channels around, and the central part is a needle holding area.

Chinese patent 201521119551.6 discloses a suture line tray packing card, and it includes upper guard plate, fixed bottom plate that links into an integrated entity, and upper guard plate and fixed bottom plate intermediate junction area are equipped with the card needle groove, and upper guard plate periphery is equipped with a plurality of location bayonet sockets, and corresponding fixed bottom plate is equipped with a plurality of location screens. Chinese patent 201520584945.2 discloses an inner package capable of containing a plurality of medical suture needles with threads, wherein the threads are orderly fixed around an inner frame, a plurality of press caps are arranged on the periphery of the inner frame, so that the threads cannot fall out of the inner frame, each needle in the central area is provided with a specific bayonet, and the threads and the suture needles are orderly arranged. Chinese patent 201811570363.3 discloses a combination package having a base member and an upper cover member of a suture track area, the edges of the package having interlocking barriers.

The above prior art packages are complex in structure and, although effective for their intended use, excessive capture reduces assembly efficiency, and in particular these packages suffer from common disadvantages: in order to prevent the suture from escaping from the package around, an equivalent bayonet lock is used, and one situation that may occur is that the suture gets stuck when the lock is closed, resulting in an unreleasable application.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a tray packaging clamp for surgical suture, which has simple structure and is more convenient to wind and pull.

The technical scheme adopted for solving the technical problems is as follows: a tray packaging clip for surgical sutures, characterized by having a base member and an upper cover member.

The base member has a bottom plate from the periphery of which a first outer wall is formed extending inwardly and upwardly at an inclination angle, preferably 45-75 degrees, and a first inner wall is formed extending vertically upwardly from the bottom plate, and needle holder means is provided extending upwardly from the bottom plate.

The upper cover member has a suture channel cover plate extending vertically downwardly about an outer circumference of the cover plate to form a second outer wall and extending vertically downwardly about an inner circumference of the cover plate to form a second inner wall leaving a line entry port in the cover plate.

The outer diameters of the bottom plate and the cover plate are equal, the free ends of the first outer wall and the second outer wall are in the same horizontal plane, and the second inner wall is overlapped with the first inner wall.

The first outer wall is inclined inwards, so that a gap for the suture thread to pass through is formed between the second outer wall and the first outer wall.

And a channel area for winding the suture thread is formed among the bottom plate, the first outer wall, the first inner wall, the cover plate, the second outer wall and the second inner wall.

The tray packaging card can be formed by arranging a plurality of protruding clamping tables on the outer surface of the first inner wall, arranging a plurality of bayonets for capturing the clamping tables on the second inner wall correspondingly and fixing the first inner wall and the second inner wall.

The inner surface of the second inner wall may be provided in a stepped shape, in correspondence with the outer surface and the top surface of the first inner wall, and the outer surface of the second inner wall may be provided in a concave shape.

The needle holding device comprises at least one suture needle clamping groove.

The base plate may also be provided with a movable elastic plate, most of the edges of which are separated from the base plate 3.

The base member and upper cover member may be made of conventional polymeric materials such as polyethylene, polypropylene or other thermoplastic materials.

Compared with the prior art, the invention has the following beneficial effects:

1. the design of no bayonet at the periphery of the tray packaging card can not cause the situation that the suture line is blocked, and the tray packaging card is more suitable for high-speed winding and assembling of the suture line;

2. the offset shielding design of the first outer wall and the second outer wall enables the suture to be trapped within the channel region.

3. The concave design of the outer surface of the second inner wall can prevent the suture line from sliding to the gap between the second inner wall and the bottom plate when the suture line is pulled and stressed, so that the suture line is pulled more smoothly;

4. the suture needle clamping grooves clamp suture needles of different types by means of elastic deformation of high polymer materials;

5. the movable elastic plate is beneficial to supporting the tail part of the needle from the bottom plate by doctors, and the needle is more convenient to take.
