Dual-joint board bending forceps

Abstract

The invention discloses dual-joint board bending forceps being used by cooperating with an anterior cervical fixation system in a spinal fixation operation. The board bending forceps are provided with a left forceps handle and a right forceps handle which are movably connected through a first connecting shaft. The dual-joint board bending forceps are structurally characterized in that the left forceps handle is composed of a left pincer head and a left handle which are fixedly connected; the right forceps handle is composed of a first right forceps head, a second right forceps head and a right handle, one end of the second right forceps head is movably connected with the first right forceps head through a second connecting shaft, and the other end of the second right forceps head is fixedly connected with the right handle; a spring is connected between the first right forceps head and the left forceps head, and a connecting rod is movably connected between the second right forceps head and the left forceps head; the head of the left forceps head is provided with a first left cushion block, and the head of the first right forceps head is provided with a first right cushion block matched with the first left cushion block; a forceps body of the left forceps head is provided with a second left cushion block, and a forceps body of the second right forceps head is provided with a second right cushion block matched with the second left cushion block. The board bending forceps have the advantages of being easy and convenient to operate, accurate in positioning, firm in clamping and high in stability.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a double-joint curved wrench used in conjunction with an anterior cervical spine fixation system in spinal fixation operations. Background technique [0002] Clinically, anterior cervical decompression and fusion (ACDF) usually uses an intervertebral fusion cage and an anterior locking plate, which can not only improve the fusion rate, but also ensure the stability of the spine. However, there are many postoperative complications of the above scheme, such as postoperative dysphagia, screw slippage, implant displacement, adjacent segment degeneration (ALD) and so on. [0003] The anterior cervical fixation system belongs to the surgical instrument for internal cervical spine fixation in clinical spine surgery, and is suitable for the treatment of lumbar disc herniation, trauma and other diseases. It includes a cervical plate and a bone screw. The cervical plate is provided with two rows o...

Problems solved by technology

The commonly used bending device is composed of left and right pliers handles, spring sheets, etc. The connection and fixation of the heads of the left and right pliers handles are all fastened by tightening screws. Cervical spine plate propped and prolapsed, resulting in failure of the operation; and in use, the forceps were not firm enough to slip off, and it was easy to withstand the head of the plate during segmental bending, resulting in internal slippage of the compressed cervical spine plate, which increased the difficulty of the operation and increased the increased risk of surgery
