Abstract

The utility model discloses a medical fixing nail belonging to the medical equipment field. The medical fixing nail consists of a nail head and a nail body provided with a barb. With the medical fixing nail, two human tissue sections can be connected together rapidly and accurately in a narrow surgical space. The utility model is suitable for the connection of human tissue such as cartilage, muscle, and ligament, with shorter surgery duration, convenient operation and wide application field.

Description

Medical staple

Technical field

The utility model discloses a kind of medical staple, belong to technical field of medical instruments.

Background technology

In surgical operation, often need to connect tissues such as isolating cartilage, muscle, ligament, connected mode commonly used at present is a suture way, but some cartilage is not suitable for suture way, and particularly at tissue size hour (in articular cavity), the sew application space is narrow, the stitching difficulty increases, when tissues such as muscle, ligament are sewed up, there is the slow defective of stitching speed in addition, brings difficulty to surgical operation.

The utility model content

The technical problems to be solved in the utility model is to reduce the used times of tissue such as connecting cartilage, muscle or ligament, can use on less tissue, is convenient to attended operation.

The technical solution of the utility model is that medical staple is made up of ailhead and nail body, has barb on the nail body.

Body is oblique backward is connected for the barb of nail on the body and nail, barb and follow closely between the body oblique slot is arranged, and barbed edge is sharp keen.

At least have two row's barbs on the nail body, have two barbs on every row's barb at least, the barb position intermeshes among the adjacent barb row.

Described ailhead is circle, in-line, triangle or L hook-type.

Described nail body is two nail bodies, and two nail body upper ends are connected together by connecting rod, have barb respectively on each nail body.

The designed medical staple of this utility model has following advantage:

1. reduce the attended operation time, applied widely.In the connection section with the isolating two parts tissue of the oblique insertion of medical staple in operation, utilize the barb on ailhead and the nail body, two parts tissue is linked together, the used operating time is lacked than suture time, and be suitable on tissues such as cartilage, muscle, ligament, using wide accommodation.

2. can under the narrow space condition, operate, be convenient to attended operation.In the use,, insert medical staple, the nail body is entered on the opposite side section, can finish connection work, in less space, also can use medical staple from a side section as long as the section of isolating two parts tissue is docking together.

When the section of two parts tissue than long time, the medical staples of available two nail bodies carry out attended operation, can further reduce the operating time.

The specific embodiment

Below by drawings and Examples this utility model is elaborated.

Embodiment 1

The structural representation of the described medical staple of present embodiment sees that Fig. 1 is to shown in Figure 4.

Medical staple is made up of ailhead 1 and nail body 2, adopt and self strengthen the making of polylactide absorbable material, front end at nail body 2 has barb 3, barb 3 oblique cutting on nail body 2 is come out, and body 2 is oblique backward is connected with nail to make barb 3, barb 3 and follow closely between the body 2 oblique slot 4 is arranged, the clear-cut margin of barb 3, be convenient to hook the tissue of section part, respectively have the barb position in row's barb 3, two row's barbs 3 to intermesh in nail body 2 front end both sides.

Ailhead 1 be shaped as in-line.Nail body 2 diameters are 1 millimeter, and length is 12 millimeters.During use, from the oblique insertion opposite side of the side section fractography of tissue, make section both sides tissue under ailhead 1 and barb 3 effects medical staple, link together.The used operating time is short, and attended operation is convenient.

Embodiment 2

The structural representation of the described medical staple of present embodiment sees that Fig. 5 is to shown in Figure 7.

The structure of the described medical staple of present embodiment and embodiment 1 are described basic identical.Difference is that two nail bodies 2 are arranged, and they are connected as a single entity with a connecting rod 5, forms two nail bodies, and connecting rod 5 can play the effect of ailhead.On the nail body 2 barb 3 is arranged, its structure is described identical with embodiment 1.

The operation principle of the medical staple of this two nail bodies is also described identical with embodiment 1, is applicable on long tissue section to connect work.
