Description
Technical Field
The utility model relates to the field of medical appliances, in particular to a clamping forceps for a cervical vertebra rear-path single-opening door plate.
Background
Cervical vertebra is a support for cranium and brain, cervical spinal marrow and other blood vessel nerves are hinges and channels for the brain to communicate with the whole body, so cervical spondylosis easily affects the brain and the whole body. With the development of information society and the change of life style, the number of people who get on table for a long time increases, so that the prevalence of cervical spondylosis is continuously increased, and the onset age tends to be younger. The spinal canal of the spine is an important channel of spinal cord, the spinal cord is a high-speed channel connected with the central nervous system and the peripheral nervous system of the brain, wherein the function of the cervical spinal cord is particularly important, and the spinal cord is in charge of both the movement, deep and shallow feeling and reflex of the two upper limbs and the movement, feeling and reflex of the two lower limbs and the information communication with the central nervous system of the brain. Compression of the spinal cord by cervical vertebral lesions can directly affect the function of the extremities. Degenerative changes are the primary cause of cervical spondylosis, and in the structures of cervical vertebrae, degeneration of the intervertebral disc is particularly important. The result of degenerative disease accumulation is disc herniation or herniation, vertebral body displacement, narrowing of the intervertebral space, and osteophyte formation. In addition, during repeated cervical flexion and extension activities of spinal cervical spondylosis patients, the protruding intervertebral disc and the posterior ligamentum flavum may form dynamic mechanical compression on the spinal cord. The cervical spinal cord and cervical nerve pressed up to this point often implement surgical treatment (such as ACDF and ACCF), and most cervical spondylosis can be usually solved, but for the case of more surgical segments or accumulation of multiple cervical intervertebral discs, a single door operation mode through the posterior cervical approach is often selected, so that the situations of spinal stenosis, cervical spinal cord compression and the like can be solved.
The cervical vertebra posterior approach single door opening operation is to directly open the cervical vertebra lamina, enlarge the sagittal diameter of the vertebral canal, relieve the compression of the front and back of the vertebral canal to the spinal cord and nerve root, and achieve the aim of decompression. The principle of the spinal canal compression decompression device is that the sagittal diameter of the spinal canal is enlarged through the posterior approach, and the compression behind the spinal cord is directly decompressed. After the door is opened, the spinal cord needs to be protected, the decompression state needs to be maintained, and a door opening plate (miniature titanium plate) needs to be used for maintaining the door opening state, so that a space without compression is created for the cervical spinal cord. The research shows that the door opening plate (micro titanium plate) is firmly fixed, achieves true rigid fixation, and is beneficial to early functional exercise. The firm placement of the opening plate is the key to the success or failure of the operation, and the operation incision is small, the operation space is limited, and the shape of the opening plate is special (the titanium plate is thin and narrow), so that the opening plate cannot be clamped by the existing operation bending forceps and needle holding instruments. In the single open operation of the posterior cervical approach, after the open door plate (micro titanium plate) is placed at the accurate position, the open door plate is often slipped due to the force of lifting the vertebral plate, so that the open door plate needs to be fixed on the vertebral plate and the lateral mass by using the fixing screw, so that the micro steel plate is prevented from slipping, and the cervical vertebra is prevented from being closed again, or the steel plate is prevented from slipping to damage and compress spinal cord.
At present, the prior art problem: in the existing surgical clamping apparatus, although the miniature steel plate can be placed at an accurate position, in the process of screwing in and fixing the tapping screw, the miniature steel plate cannot be maintained at the original proper position, so that an operator often has difficulty in finishing the fixing operation of screws on two sides of the door opening plate, and the position of the miniature steel plate needs to be adjusted by repeatedly using the existing clamping apparatus, thereby increasing the operation time and the related damage risk in the operation.
Disclosure of Invention

The finger ring 1 is located at the tail end of the straight clamp rod 3, the first arc clamp rod 41 and the second arc clamp rod 42 are extending from the straight clamp rod 4 to the head end, the first arc clamp rod 41 and the second arc clamp rod 42 are mutually hinged through the hinging part 5 and extend to the head end to form a clamp arm 6, and the first clamping groove 71 and the second clamping groove 72 are respectively located at the front end of the clamp arm 6.
Further, the first clamping groove 71 and the second clamping groove 72 are located at the front end of the forceps arm 6, and are grooves for clamping an open door plate used in the cervical vertebra posterior single door opening operation, and an included angle of 15-60 degrees is formed between the longitudinal axis direction of the first clamping groove 71 and the second clamping groove 72 and the transverse axis of the forceps arm 6. The door opening plate can be firmly clamped, and meanwhile, the door opening plate can be conveniently and accurately placed at a proper position, so that the bolts are fixed.
Further, the first arc clamp bar 41 and the second arc clamp bar 42 may form a circle-like structure in the locked state of the locking portion 2, and the circle-like structure provides a channel for installing a tapping screw for the device; when the device firmly clamps the door opening plate and places the door opening plate on an accurate door opening position, a fixed self-tapping screw can be used for completing screw installation operation on the inner vertebral plate through the channel, so that the door opening plate is stably fixed on the vertebral body.
Further, by the locking parts 2 located at the upper ends of the straight clamp rods 3, when the door plate is clamped and opened by the device, the clamping pliers can be locked by the clamping locks between the locking parts 2, so that the door plate is firmly clamped in the grooves of the first clamping groove 71 and the second clamping groove 72, and is not easy to slip and fall. The device is convenient for the operator to change hands or hold by an assistant, so that the operator can finish the nail placing operation conveniently without the need of whole-course gripping, the sliding of the door opening plate is reduced, and the risk of damaging the exposed spinal cord of the neck is reduced.
The utility model has the functions and effects of
The clamping pliers for the cervical vertebra rear single-open door plate are integrally of a pliers structure, and after the door opening plate is placed in the clamping groove in the cervical vertebra rear single-open operation, the door opening plate can be firmly locked in the groove through the locking part, so that looseness or slippage is not easy to occur. When the door opening plate is accurately placed at the position of the vertebral plate for opening the door, the door opening plate can be continuously clamped by the device for placing the fixing screw, so that the position of the door opening plate is prevented from moving after the clamping device is loosened in the past, the position of the door opening plate is repeatedly adjusted, and unnecessary operation time of an operation is shortened. The operator or the assistant will open the door board one end through self-tapping screw and fix, and open the door the board other end and then can pass through the circular passageway of class that the arc clip pole constitutes, fix self-tapping screw on the lamina, open the door plant when upper and lower end and all fix and finish, loosen and open the locking part, can take off this device, make things convenient for the operation greatly, shorten operation unnecessary time, improve operation efficiency.
