Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

Referring to fig. 1 to 3, the bone-holding forceps comprise two forceps handles 1, two forceps heads 2 and a locking device, wherein the two forceps handles 1 are connected in an X-shaped shaft, the two forceps heads 2 are respectively arranged at one end of the two forceps handles 1, the locking device is arranged at the other end of the two forceps handles 1, the two forceps heads 2 are driven to approach and clamp a bone by holding the forceps handles 1 in an operation, and the holding ends of the two forceps handles 1 are locked by the locking device. Because traditional holding forceps is only applicable to the condition of front and back fracture displacement, and when the displacement of controlling the fracture is operated, have horizontal operating space not enough and inconvenient condition, consequently, with one of them one end fixedly connected with first lateral extension handle 5 of pincers handle 1, the one end swing joint of another pincers handle 1 has second lateral extension handle 6, first lateral extension handle 5 is the parallel state setting with second lateral extension handle 6, two binding clip 2 are fixed respectively and are set up in the free end of first lateral extension handle 5 and second lateral extension handle 6, through this mode, change the exposed core of traditional holding forceps to the side of whole holding forceps by original pincers handle 1 head end, thereby make holding forceps can carry out horizontal operation, thereby be convenient for add to control the fracture displacement and hold fixedly.

The first lateral extension handle 5 is integrally formed at one end of the corresponding forceps handle 1 in a bending mode. When the bone holding forceps are used, the forceps handle 1 with the first lateral extension handle 5 is a fixed handle, the forceps handle 1 is kept still in the operation process, and the other forceps handle 1 is used for driving the corresponding forceps head 2 to approach to tightly.

One end of the second lateral extension handle 6 is connected with the corresponding forceps handle 1 through a movable shaft 7, and the movable shaft 7 is in telescopic connection with the end part of the forceps handle 1. The second lateral extension handle 6 is driven to extend outwards by holding the forceps handle 1, so that the second lateral extension handle 6 drives the forceps heads 2 connected with the second lateral extension handle to move outwards, and the distance between the two forceps heads 2 is increased, so that the bone can be accommodated conveniently.

One end of the second lateral extension handle 6, which is far away from the forceps head 2, is fixedly provided with a hinge portion 8, one end of the movable shaft 7 is connected with the hinge portion 8 through a shaft nail 9, and the other end of the movable shaft 7 is movably inserted into one end of the corresponding forceps handle 1. The second lateral extension rod drives the connected forceps head 2 to approach towards the other forceps head 2 by holding the forceps handle 1 until the bones are clamped together, the inner surface of the forceps head 2 is provided with teeth 10, each tooth 10 is blunt, and the teeth 10 are aligned when the two forceps heads 2 are folded. In the process, the second lateral extension handle 6 moves towards the forceps handle 1 connected to the first lateral extension handle 5, so that the movable shaft 7 is gradually retracted into the head end of the forceps handle 1, and the other end of the movable shaft 7 is correspondingly rotated to adapt to the change in length by the shaft nail 9 and the second lateral extension handle 6.

First lateral extension handle 5 is the laminating setting with second lateral extension handle 6, and the common cover in the outside of the two is equipped with a plurality of stop collar 11, stop collar 11 passes through first screw 12 and first lateral extension handle 5 fixed connection. Guarantee the state that first lateral extension handle 5 and second lateral extension handle 6 remain parallel laminating throughout through a plurality of stop collar 11, and then guarantee that two binding clip 2 can be close to each other or keep away from along linear direction. The stop collar 11 is fixedly mounted on the first lateral extension handle 5 through a first screw 12, and the other end of the stop collar 11 is attached to and penetrates through the second lateral extension handle 6.

The end parts of the first lateral extension handle 5 and the second lateral extension handle 6 are respectively fixedly connected with the two binding clip heads 2 through two second screws 13, a positioning hole 14 is formed in the back side of each binding clip head 2, and positioning pins 15 matched with the positioning holes 14 are fixedly arranged at the end parts of the first lateral extension handle 5 and the second lateral extension handle 6. After the positioning hole 14 is aligned with the positioning pin 15 and sleeved in the installation process of the binding clip 2, the second screw 13 is used for fixing the binding clip 2, and the rotation of the binding clip 2 in the use process is avoided by the arrangement of the positioning pin 15.

One end of the second lateral extension handle 6 is provided with a bend avoidance portion 16 for enlarging the working space. A total of two forceps heads 2 have larger space between them for bone clamping operation.

The maximum distance between the tail of the holding end of each forceps handle 1 and the X-shaped shaft joint is 14cm, the maximum distance between the head end of each forceps handle 1 and the X-shaped shaft joint is 6cm, and the distance between the head ends of the two forceps handles 1 is 4 cm.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
