Description

Technical Field

[0001] The utility model relates to a striking device, in particular to an ice-skate type intraspinal striking device. Background Art

[0002] The bottom of the striker used in the prior art is flat, and the compressing object protruding into the spinal canal can be slowly flattened and put back into the intervertebral space. However, the flattened compressing object cannot be directly removed and needs to be bitten off with bone chisels, gun pliers, etc., which has certain risks. If the pressure-causing object closely attached to the dura mater is directly stepped on and broken by force with a foot pedal, when the pressure-causing object is in the shape of a hill, it is easy to slide and the striking range cannot be controlled. At the same time, it is easy to damage the surrounding dura mater and nerves after sliding.

[0003] In the prior art, L-shaped osteotome and various curved bone knives used in surgery require that the pressure-causing object be separated from the dura mater sac first, and a certain gap be formed between the two before the osteotome is inserted to remove the pressure-causing object. At the same time, because some pressure-causing objects are hilly, the point of force is easy to slip when the osteotome is used to remove them directly, thereby damaging nerves.

[0024] The utility model is further described below in conjunction with the accompanying drawings.

[0025] like Figure 1 , 2 As shown, an ice skate type intraspinal striker comprises a flattening head 1, a handle 4 and a straight rod 3 connecting the flattening head 1 and the handle 4. A metal hard striker is arranged at the tail end of the handle 4. Figure 3 , 4 As shown, a blade 2 is integrally provided on the bottom surface of the treading head 1 . The blade 2 is located on the center line of the bottom surface of the treading head 1 and protrudes from the bottom surface of the treading head 1 .

[0026] The length of the treading head 1 is 8 mm, the width is 4 mm, and the thickness is 2 mm. The length of the blade 2 is 8 mm, the width is 1 mm, and the thickness is 1 mm. The length of the straight rod 3 is 10 cm, the diameter of the contact end of the straight rod 3 and the handle 4 is 5 mm, and the diameter of the contact end of the straight rod 3 and the treading head 1 is 4 mm. The length of the handle 4 is 8 mm, the width is 2 mm, and the thickness is 1.5 mm. In this embodiment, the angle between the straight rod 3 and the treading head 1 is 90°. In actual use, the angle between the straight rod 3 and the treading head 1 can be designed to be 120° as needed.

[0027] Preferably, the bottom surface of the treading head 1 is provided with anti-skid stripes 5 which are processed in an axisymmetric manner on the left and right sides of the blade 2. The bidirectional oblique corrugations have certain levels and are relatively rough, which can prevent slipping.

[0028] When using, after removing the nucleus pulposus tissue in the intervertebral space, slowly extend the foot of the head end of the striker into the protruding intervertebral disc and other pressure-causing objects, the dura mater sac, and the nerves to separate them left and right and front and back. After separation, place the foot on the surface of the protruding intervertebral disc, calcified intervertebral disc, etc., and gently strike to flatten the pressure-causing objects and return them to the intervertebral space. Applying a little force can cut off the edge of the pressure-causing object, and the pressure-causing object will be free on the upper and lower sides, the head and tail sections, and the rear end, with only the front section still connected, and can be bitten off with the nucleus pulposus forceps.

[0029] It has three main functions, which can separate the compressing object from the dura mater sac, flatten the compressing object, and cut off the compressing object. ① It can be slowly inserted between the compressing object and the dura mater sac to slowly separate the two. ② After separation, gently hit the surface of the compressing object to flatten it. ③ Apply a certain impact force to the edge of the compressing object at the posterior edge of the vertebral body, which can cut off the edge of the compressing object, and then it can be bitten off with a nucleus pulposus forceps.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
