Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

A folding adjustable needle forceps is shown in figure 1-2 and comprises a first forceps arm and a second forceps arm, wherein a connecting shaft 1 is fixedly connected to the first forceps arm, the second forceps arm is in X-shaped cross rotation connection with the first forceps arm through the connecting shaft 1, the first forceps arm and the second forceps arm are divided into forceps heads 2 and forceps handles 3 by taking the connecting shaft 1 as a boundary, an accommodating space 4 is formed inside the end parts of the two forceps heads 2, and a clamping head 5 which extends to the outside of the accommodating space 4 and is used for clamping a suture needle is detachably connected in the accommodating space 4; the surfaces of the two forceps handles 3 close to each other are provided with fixing pieces.

As shown in fig. 1-2, after the clamping head 5 of the forceps head 2 is worn, the needle holder according to the present application can disassemble the clamping head 5, and only the clamping head 5 is replaced, so that the material consumed by the connecting shaft 1, the first forceps arm and the second forceps arm is saved while the use is ensured, and the waste of medical resources can be reduced to a certain extent.

As shown in fig. 1-2, a first thread groove 6 communicated with the accommodating space 4 is formed on the shaft wall of the binding clip 2, a fixing bolt 7 is connected to the first thread groove 6 through an internal thread, the outer shaft wall of the clamping head 5 is attached to the inner wall of the accommodating space 4, and a second thread groove 8 matched with the fixing bolt 7 is recessed on the outer shaft wall of the clamping head 5.

As shown in fig. 2, the outer shaft walls of the two clamping heads 5 close to each other are formed with clamping planes 9 attached to each other, and the clamping planes 9 are provided with staggered latticed anti-slip patterns.

As shown in fig. 1-2, when the clamping head 5 needs to be replaced, the fixing bolt 7 is first forced to rotate in the first thread groove 6 in a direction away from the binding clip 2, and the fixing bolt 7 will rotate out of the second thread groove 8, so that the clamping head 5 can be taken out of the accommodating space 4 to replace a new clamping head 5; the new clamping head 5 is replaced by firstly placing the part of the clamping head 5 in the accommodating space 4, enabling the second thread groove 8 to be positioned under the fixing bolt 7, then rotating the fixing bolt 7 towards the direction close to the tong head 2, enabling the fixing bolt to abut against the second thread groove 8, and further abutting against the whole clamping head 5, so that the clamping head 5 can be stably installed on the first tong arm and the second tong arm, and the use is guaranteed; and in order to further ensure the stability, the clamping plane 9 with the antiskid veins formed on the clamping head 5 can have better and stable contact with the suture needle.

As shown in fig. 1-2, the fixing element includes a first fixing block 10 and a second fixing block 11 rotatably connected to the outer axial walls of the two forceps handles 3 adjacent to each other, respectively, a clamping groove 12 is formed on the surface of the first fixing block 10 adjacent to the second fixing block 11, a clamping block 13 is fixedly connected to the surface of the second fixing block 11 adjacent to the first fixing block 10, and the length of the clamping groove 12 is greater than that of the clamping block 13; when the clamping head 5 clamps the suture needle, the first fixing block 10 and the second fixing block 11 are rotated so that the latch 13 is positioned in the latch groove 12.
