Technical Field

The invention relates to a multifunctional rongeur for spinal surgery, belonging to the field of medical surgical instruments.

Background

Nerve damage caused by the ventral compression of the dural sac in the vertebral canal is one of the main factors and indicators of spinal surgery. The pressure-inducing substance mainly comprises spinal fracture, tumor, ligament calcification, intervertebral disc protrusion, etc. The operation of posterior approach of spinal column is a safe, effective and mature technique for the pressure reduction of the dorsal and ventral sides of the dura mater sac. However, when deformity correction or lesion removal is involved, it is often necessary to remove the pressure inducing substance with a tool and even to enlarge the surrounding tissue. Particularly, due to the shielding of the dural sac, the pressure object caused by treating the ventral side in the posterior spinal surgery can not be taken out under direct vision, and a tool is often required to be wound to the ventral side of the dural sac, or the pressure object is collapsed to the front by adopting forward striking and then taken out by using rongeur. The existing common rongeur for spinal surgery is usually a straight forceps head, is difficult to wind to the ventral side of a dura mater, needs to enlarge an operative field, increases tissue traction and exposure, aggravates wounds, is difficult to take out ventral median and contralateral tissues, increases operation time and difficulty, is serious in wound surface bleeding when bone and soft tissues are cleared in blocks, is attracted by an assistant, is particularly blocked in view under the condition of not fitting tacit, and is easy to generate side damage by misoperation. For the reasons, the invention discloses a multifunctional rongeur which can be used as a malleus device and is provided with a suction device, and the purposes of shortening the operation time, optimizing the operation process and improving the operation efficiency are achieved by simplifying the procedure and reducing the steps.

The left handle is connected with the left tong head, the middle part of the left handle protrudes outwards in an arc shape, and two ends of the left handle are vertically arranged; the bottom end of the left handle is provided with a chute for the left handle to slide left and right on the screw; the screw piece comprises a screw connecting rod and a screw end; one end of the screw connecting rod is connected with the inner side surface of the bottom end of the right handle, and the other end of the screw connecting rod penetrates through the sliding groove at the bottom of the left handle and is connected with the end head of the screw; the bottom of the middle of the screw connecting rod is provided with a cylindrical block;

the left handle is connected with the protruding part of the inner side edge of the middle part of the right handle; the handle of the handle and the surface of the bottom of the tong head are provided with a hobbing cutter pattern anti-slip design.

furthermore, the forceps head and the handle are designed to form a 90-degree right angle; the front end of the suction tube is flush with the bottom of the forceps head, and the tail end of the suction tube extends out of the end of the right handle by 1 cm.

Furthermore, the left handle is hinged with the middle inner side edge protruding part of the right handle.

Furthermore, the whole body is made of stainless steel.

Furthermore, the number of the elastic sheets is 2, and the two elastic sheets are arranged in a crossed manner.

The invention has the beneficial effects that: this patent can regard as the hammering bone ware to from multi-functional rongeur of taking suction device. The section after it bites is more level and smooth, and the tissue that once bites is removed is more, and the operation is high-efficient. Especially, the clamp head elbow is designed to be capable of winding to the abdominal side of the dural sac for operation, and when the abdominal side of the dural sac is operated, hematocele in an operation area can be synchronously absorbed, so that the visual field is clearer. And the rongeur can be directly used as a malleus device after the tail end screw cap is screwed down, excessive operation in a spinal cord or nerve area due to the replacement of an operation tool is not needed, the disturbance to the spinal cord and nerves is reduced, and the risk of iatrogenic nerve injury is reduced. Meanwhile, by simplifying the procedure, the steps are reduced, and the purposes of shortening the operation time, optimizing the operation process and improving the operation efficiency are achieved.

the whole body is made of stainless steel, so that the cleaning and the disinfection are convenient, and the cleaning and the disinfection can be repeatedly used.

The number of the elastic pieces 3 is 2, and the elastic pieces are arranged in a crossed manner, so that the stability is improved.

the forceps head 2 is designed to be right-angled, and the bottom plate is flat, so that the section of the biting part is flat, and secondary trimming is not needed. Meanwhile, due to the right-angled characteristic of the binding clip 2, the binding clip can bypass the dural sac to bite bones and soft tissues such as posterior edge sclerotin and posterior longitudinal ligament of the vertebral body on the ventral side of the dural sac.

when the handle 1 is tightly grasped to enable the left tong head and the right tong head to be close, and the end socket 4-2 of the screw port at the end is screwed to enable the tong head 2 to be fixed, the rongeur is converted into a bone hammering device, and the bottom surfaces of the handle 1 and the tong head 2 are provided with the anti-skidding design of the embedded hob flowers so as to be beneficial to grasping and anchoring the bone surface. The hammer is used for knocking the cylindrical block 7 on the screw to conduct downward, so that the hammer plays a role in hammering sclerotin. The front end of the right suction tube 5 is parallel to the right angle of the right forceps head 2-2, and the electric suction device is connected with the tail end extending part, so that blood in an operation area can be directly sucked completely when the rongeur is used after being converted into a bone hammering device, and safe and accurate operation is facilitated.

This patent can regard as the hammering bone ware to from multi-functional rongeur of taking suction device. The section after it bites is more level and smooth, and the tissue that once bites is removed is more, and the operation is high-efficient. Especially, when the operation is performed on the abdominal side of the dural sac, the hematocele in the operation area can be synchronously sucked and removed, so that the visual field is clearer. And the screw cap at the tail end can be directly used as a malleus device after being screwed down, so that the operation tool does not need to be replaced, the disturbance to the spinal cord and the nerves is reduced, and the risk of nerve injury is reduced. Meanwhile, by simplifying the procedure, the steps are reduced, and the purposes of shortening the operation time, optimizing the operation process and improving the operation efficiency are achieved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
