Description

Technical Field

[0001] The utility model relates to the technical field of neurosurgery, in particular to a bone-holding forceps fixing device for neurosurgery. Background Art

[0002] In neurosurgery, rongeurs are often used to fix bones. For example, in spinal surgery, doctors will use rongeurs to fix spinal bones to help correct spinal deformities or restore spinal stability to ensure the success and safety of the operation. Of course, in some special cases, during repair surgery for spinal fractures, rongeurs need to bite off the bones at this time to facilitate repositioning of the fracture ends and fixation of the fracture site.

[0003] In this operation, rongeurs are usually reusable instruments. As time goes by during use, the blade of the rongeurs may become loose or worn, resulting in dislocation, affecting the bite effect. Although multiple rongeurs are generally prepared for use during surgery, in actual surgery, it is difficult to predict with the naked eye whether the blade of the reused rongeurs is dislocated, and it is impossible to determine whether the blade of the spare rongeurs is easy to use. If the bite of the replaced rongeurs is still not smooth, the rongeurs can only be shaken to bite the required part during the bone biting process. At this time, it is easy to cause damage to other parts during the shaking process, affecting the surgical effect. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 and Figure 2 The utility model provides a technical solution: a rongeur fixation device for neurosurgery, comprising a rongeur body 1, calibration blocks 1 2 are fixedly installed on both sides of the rongeur body 1 near the jaw joint, calibration blocks 2 3 are fixedly installed on both sides of the rongeur body 1 near the handle joint, calibration block 3 4 is movably installed on one end of calibration block 2 3 away from the handle of the rongeur body 1, calibration block 3 4 is located on the outside of the middle joint of the rongeur body 1, and calibration blocks 1 2, 2 3 and 3 4 are respectively designed at several joints of the rongeur body 1 for coordinated use. Under normal circumstances, since the rongeur body 1 opens and closes, only the middle joint opens. At this time, since the calibration block 3 4 itself is not fixed on the rongeur body 1, it will not be affected by the use of the rongeur body 1. The rotation accuracy is ensured in the later period when the blade of the rongeur body 1 is offset;

[0026] It also includes an adjustment component for adjusting the position of the jaws of the bone-holding forceps body 1. The adjustment component is located between the calibration block three 4 and the calibration block one 2. The adjustment component can install the calibration block one 2 and the calibration block three 4 on both sides of the bone-holding forceps body 1 together, respectively, and adjust the position of the blade of the bone-holding forceps body 1 to facilitate the adjustment of the blade misalignment.

[0027] Furthermore, the surfaces of the two calibration blocks 1 2 near the pliers head are provided with receiving grooves 5, and the interior of the receiving grooves 5 is detachably installed with an adjustment component, and the receiving grooves 5 can store the adjustment component when the cutting edge of the bone biting forceps body 1 does not need to be calibrated.

[0028] Furthermore, the adjustment component includes a calibration groove 16 provided at one end of the calibration block 2 near the calibration block 3 4, a calibration groove 2 7 is provided at one end of the calibration block 3 4 near the calibration block 2, the centers of the calibration groove 1 6 and the calibration groove 2 7 are located on the same axis, and a fixing part for fixing the calibration block 3 4 and the calibration block 2 is provided between the calibration groove 1 6 and the calibration groove 2 7. Because the positions of the calibration groove 1 6 and the calibration groove 2 7 completely overlap under normal circumstances, whether the blade of the bone biting forceps body 1 is misaligned can be judged by observing whether the positions of the calibration groove 1 6 and the calibration groove 2 7 completely overlap.

[0029] Furthermore, the fixing part includes a calibration rod 8 movably inserted into the calibration groove 1 6 and the calibration groove 2 7, a fixing ring 1 9 is fixedly installed on the end of the calibration rod 8 close to the bone-binding forceps body 1, and a fixing ring 2 10 is threadedly installed on the end of the calibration rod 8 away from the bone-binding forceps body 1, and a telescopic part for connecting the two calibration rods 8 is provided between the two calibration rods 8. The use of the fixing part can fix the calibration block 1 2 and the calibration block 3 4 to prevent them from loosening when adjusting their position.

[0030] See also Figure 3 Zhihe Figure 4 The utility model provides a technical solution: further, a gasket 11 is fixedly installed on one side of a fixing ring 9 close to a calibration block 2, and the gasket 11 is made of an elastic material. The design of the gasket 11 allows the fixing ring 9 to better fill the tiny gap between the calibration block 2 when in contact with the fixing ring 9, and can better ensure the stability and accuracy of the bone biting forceps body 1 when in use.

[0031] Furthermore, a gasket 2 12 is fixedly installed on one side of the fixing ring 2 10 close to the calibration block 3 4. The gasket 2 12 is made of an elastic material. The design of the gasket 2 12 allows the fixing ring 2 10 to better fill the tiny gap therebetween when in contact with the calibration block 3 4, and can better ensure the stability and accuracy of the bone biting forceps body 1 when in use.

[0032] Furthermore, the telescopic part includes a movable rod 13 and a sleeve rod 14 which are movably mounted on the two calibration rods 8 near one end of the bone-holding forceps body 1, and the sleeve rod 14 is movably sleeved on the outer side of the movable rod 13. The design of the movable rod 13 and the sleeve rod 14 can better allow the bone-holding forceps body 1 to maintain the stability between the calibration blocks 1 2 and 3 4 on both sides when in use.

[0033] Furthermore, the length of the movable sleeve connection between the sleeve rod 14 and the movable rod 13 is greater than the distance opened at the joint of the bone rongeur body 1, so as to prevent the bone rongeur body 1 from being loosened due to insufficient sleeve connection length between the sleeve rod 14 and the movable rod 13 when the bone rongeur body 1 is in use.

[0034] Working principle: During the preoperative preparation, the neurosurgery rongeur fixation device can determine whether the cutting edge of the rongeur body 1 is misaligned by observing whether the positions of the calibration slot 1 6 and the calibration slot 2 7 are completely overlapped. This method can help doctors determine whether the cutting edge of the rongeur body 1 is misaligned before the operation, thereby improving the efficiency of the intraoperative operation and reducing unnecessary delays and adjustments during the operation.

[0035] In addition, if it is observed that the positions of calibration groove 1 6 and calibration groove 2 7 do not coincide, it means that the blade of the bone biting forceps body 1 is offset and the cutting edge is misaligned in this state. At this time, the adjustment component can be taken out from the storage groove 5, and then the two calibration rods 8 are respectively passed through the calibration groove 1 6 and calibration groove 2 7 in turn, and the gasket 11 on the fixing ring 1 9 is pressed against the calibration block 1 2. Then, the fixing ring 2 10 is threadedly installed on the other end of the calibration rod 8 and fixed against the calibration block 3 4, thereby adjusting the positions of the calibration blocks 1 2 and 3 4, and manually fine-tuning and calibrating the positions of the calibration groove 1 6 and the calibration groove 2 7 to make their positions coincide. This method, combined with the method of observing whether the cutting edge is misaligned by the naked eye, can be corrected in time when the cutting edge is misaligned before the operation, thereby increasing the precision and accuracy during the operation, reducing the uncertainty factors during the operation, and helping to improve the efficiency and smoothness of the operation, saving operation time and resource costs.

[0036] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
