[0002] In the treatment of skull defects, skull repair surgery is a key means. However, existing skull repair devices and related auxiliary equipment have many deficiencies. The traditional titanium mesh skull repair surgery requires craniotomy, with a large surgical incision and injury, a long operation time, and the inability to adjust the size of the titanium mesh, resulting in high practical and economic costs. Moreover, it is difficult to accurately fit complex-shaped skull defect sites, especially for large-area and irregular defects, and the fitting effect is not ideal. At the same time, there is a lack of effective real-time guidance means during the operation to assist in the precise placement of repair materials, and the fixation method also has problems such as insufficient stability and being unfavorable for postoperative recovery.

[0003] Therefore, it is necessary to develop a new type of skull repair and fixation device that can overcome the above defects and better meet clinical needs. The ultrasonic-guided small-incision minimally invasive treatment is used for skull repair and fixation, with small injury, fast operation time, simple operation process, low surgical risk, fast postoperative recovery, a large reduction in practical and economic costs, no need to privately customize and reserve the operation time, and the ability to repair and fix at any time and be discharged on the same day. Summary of the Invention

[0004] The present invention aims to provide an ultrasonic-guided extensible skull repair and fixation device to solve the problems of the traditional titanium mesh skull repair surgery in the prior art, which requires craniotomy, has a large surgical incision and injury, a long operation time, and the inability to adjust the size of the titanium mesh, resulting in high practical and economic costs.

[0014] Further, a channel one and a channel two are formed on both sides of the housing. One ends of the channel one and the channel two are open at the insertion end of the housing, and the other ends of the channel one and the channel two are open at the handle end of the housing.

[0015] The beneficial effects of this technical solution are as follows:

[0016] (1) Through the cooperation of the control device, the processor, the adjusting device, and the folding plate and the titanium plate, flexible adjustment and extension can be carried out according to the complex shapes of skull defects of different patients, achieving high fitting with the defect site, improving the repair effect, and reducing the occurrence of postoperative complications.

[0037] The specific implementation process is as follows:

[0038] According to the preoperative cranial CT and other imaging data of the patient, evaluate the specific situation of the skull defect, select the device of the present invention with appropriate size and specifications, check whether each component is complete and the connection is firm, ensure that the device is in a normal use state, connect the external ultrasound device to this device, prepare an infusion device for liquid circulation, and reliably connect the infusion device to the water inlet 302.

[0039] Subsequently, connect and fix the device to the operating table or other predetermined external support structures accurately through the connection device 2, and ensure that the device is in a state convenient for operation and stable in position by adjusting components such as the connection shaft 203.

[0040] The operator wears the control glove 301, starts the device, controls the telescopic rod 5 to perform preliminary telescopic actions through hand movements, adjusts the overall spatial position of the device, so that it drives the titanium plate 7 close to the skull defect area; at the same time, operates the adjustment device 6 with the control glove 301 to drive the folding plate 8 to unfold into a fan shape, and at the same time drive the titanium plate 7 to perform initial angle and position adjustments to roughly align with the skull defect site.

[0041] Under the guidance of the ultrasonic device, the operator continues to finely adjust the adjusting device 6 through the control glove 301, causing the titanium plate 7 to slide, fold, etc. along the folding slide rail 801 within the folding groove 802. Meanwhile, in coordination with the further telescopic adjustment of the telescopic rod 5, the titanium plate 7 is gradually made to fully conform to the skull defect site. During this process, continuous adjustments are made according to the feedback of the ultrasonic image until an ideal conforming state is achieved.

[0042] After the position of the titanium plate 7 is determined, the titanium plate 7 is firmly fixed to the skull using conventional skull fixation means. If temperature adjustment of the titanium plate 7 is required during the operation to achieve the purpose of hardening and softening the titanium plate 7, then the corresponding liquid is injected into the water inlet 302 through the infusion device, causing it to circulate within the circulating water pipe 702 to achieve the corresponding function.

[0043] After the operation is completed, the ultrasonic device is used again to check the position of the titanium plate 7 after fixation and its relationship with the surrounding tissues. After confirmation, the connection between the device and the external device is removed to complete the surgical operation.

[0044] Working principle: During the skull repair operation, the operator first firmly connects this device to the operating table or other suitable external support structure through the connecting device 2. Then, the operator wears the control glove 301, and various hand movements are captured by the sensors on the inner wall of the glove and converted into electrical signals and transmitted to the processor 4. After receiving the signals, the processor 4 analyzes and judges according to the preset control algorithm, generates corresponding control instructions, and drives the telescopic rod 5 to perform telescopic movements to adjust the position of the device in space; at the same time, the adjusting device 6 is controlled to rotate, thereby driving the folding plate 8 to unfold into a fan shape, driving the internal titanium plate 7 to be adjusted in terms of angle, position, etc., enabling the titanium plate 7 to be extended, folded, etc. according to the shape of the skull defect to better conform to the defect site;

[0045] In addition, when temperature adjustment operation of the titanium plate 7 is required, the corresponding liquid can be injected into the water inlet 302 through an external infusion device, etc. The liquid enters the circulating water pipe 702 through the connecting pipe 701. When hot water circulates within the circulating water pipe 702, the titanium plate 7 is strengthened and hardened to ensure the strength of the titanium plate 7. When cold water circulates, the titanium plate 7 softens and reduces hardness, thereby realizing the function of adjusting the titanium plate 7. Throughout the process, with the coordinated cooperation of the various components of the device, under ultrasonic guidance, precise and efficient skull repair operations are achieved.

[0046] The above are only embodiments of the present invention, and common general technical solutions or characteristics in the solutions are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solutions of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
