Description
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, does not damage the surface layer of tissue.
The technical solution of the utility model is that medical staple is made up of ailhead and nail body, is threaded in the front portion of nail body.
The front end of described nail body is the epiconus capitiform.
Be with stop washer on the nail body under ailhead.
Have stop tooth below the described stop washer.
The designed medical staple of this utility model has following advantage:
1. reduce the attended operation time, applied widely.In operation with in the oblique connection section that is screwed into isolating two parts tissue of medical staple, utilize the screw thread on ailhead and the nail body, two parts tissue is linked together, perhaps when connecting two parts tissue with connection strap, medical staple can be fixed on connection strap on the tissue, and two parts tissue is linked together.Used time of this attended operation is short, and is applicable on tissues such as cartilage, muscle, ligament and uses wide accommodation.
2. do not damage the surface layer of tissue in operation.Owing to below the ailhead of medical staple, be with stop washer; medical staple is when being screwed into tissue; ailhead does not contact with the tissue surface; thereby when twisting medical staple; tissue surface layer under the ailhead can not rotate with ailhead, thereby protection tissue surface layer is injury-free.Have stop tooth below the stop washer, can with tissue surface layer excellent contact, keep stopper ring not rotate.
3. rational in infrastructure, be convenient to attended operation.Medical staple front end has epiconus, and the doctor can utilize epiconus to position, and makes medical staple thrust tissue, finishes the work of being located by connecting fast, makes attended operation simple and easy to do.
Description of drawings
Fig. 1 is a kind of front view of medical staple.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is that the A of Fig. 1 is to view.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is elaborated.
Medical staple is made up of ailhead 1 and nail body 2, adopts self to strengthen the making of polylactide absorbable material, is threaded 3 at the front end of following closely body 2, and the pitch of thread is bigger, has epiconus 4 at the front end of following closely body 2.On the nail body 2 under the ailhead 1, be with stop washer 5, below stop washer 5, have eight stop tooths 6.The structural representation of medical staple sees that Fig. 1 is to shown in Figure 3.
In operation, the doctor aims at the position that will connect with medical staple, with screwdriver medical staple is screwed into connecting portion and can finishes connection work, and is simple and efficient to handle.In use, medical staple front end epiconus makes the doctor be convenient to the location, thrust and want the junction, and stop washer can prevent that the tissue surface layer from rotating with ailhead, avoids the tissue surface layer to incur loss.
