Detailed Description

Embodiment one:

The utility model proposes a fixing device for a metal surgical suture, as shown in figures 1, 2 and 3, comprising a metal tube 3, a sleeve 1 and a handle 2.

As shown in fig. 1, a metal tube 3 is coaxially provided inside a sleeve 1, and a handle 2 is mounted on the circumferential side of the sleeve 1.

In order to ensure that the fixing device for the metal surgical suture provides good safety guarantee and comfort when the fixing device is in contact with a human body, the handle 2 and the sleeve 1 are made of soft plastic materials such as rubber, silica gel and the like, so that medical staff can conveniently hold the sleeve 1 to fix the metal suture 5.

The metal tube 3 should be deformable under a certain stress, have a certain toughness, and not break during deformation, and the metal tube 3 may be made of stainless steel, titanium or titanium alloy.

As shown in fig. 3, in the present embodiment, the metal pipe 3 is divided into a first pipe section 31, a second pipe section 32, and a third pipe section 33 from one end to the other end in the axial direction, the diameter of the second pipe section 32 being equal to the diameters of the first pipe section 31 and the third pipe section 33 (the inner wall of the metal pipe 3 is a straight pipe-like structure); the second pipe section 32 is in transitional connection with the first pipe section 31 and the third pipe section 33;

The wall diameters of the corresponding positions of the sleeve 1 are respectively matched with those of the first pipe section 31, the second pipe section 32 and the third pipe section 33.

In order to prevent medical staff and patients from being scratched, the axial length of the metal tube 3 is smaller than that of the cannula 1, and the metal tube 3 is disposed in the middle of the cannula 1.

The working principle of the utility model is as follows:

As shown in fig. 6-9, after the needle holder 4 is used by medical staff to clamp and bend the sleeve 1, the metal tube 3 at the inner side of the sleeve 1 deforms to squeeze the metal suture 5, so that the metal suture 5 is forced to deform to form a folding point, the metal suture 5 is not easy to escape from the closed position of the metal tube 3, and the bending changes the stress direction of the metal suture 5 to form force decomposition, so that the fixing effect of the metal suture 5 is amplified.

The application method of the utility model is as follows:

step 1: as shown in fig. 6, a metal suture 5 is passed through the sleeve 1;

Step 2: as shown in fig. 7-9, the needle holder 4 is used to clamp one end of the sleeve 1 and bend it, the bent sleeve 1 forms an included angle at the folding point, and the metal tube 3 inside the sleeve 1 presses the metal suture 5 and forces it to deform.
