[0036] With the gradual development of thyroid surgery technology, the concept of cosmetic minimally invasive has gradually been accepted. Since Huscher performed endoscopic thyroid lobectomy and achieved success in 1997, endoscopic thyroid surgery has developed into a mature stage. More and more hospitals have carried out this surgical method. Because of its hidden incision, good cosmetic effect and fewer complications, it has gradually become an important method for benign thyroid tumors and low-grade thyroid tumors. However, in actual operation, there is no natural space in the neck, the operation space is small, and the exposure of the tumor is difficult. In view of the above technical problems, the utility model provides a thyroid endoscopic surgery space expansion device, which can expand the operation space by lifting and adjusting during operation. Medical staff can adjust the exposure angle of the operation according to the actual needs, and has the advantages of high flexibility. The technical scheme of the utility model will be described in detail below with specific examples.
[0037] Referring to Figure 1 , Figure 2 and Figure 3 , the utility model relates to a thyroid endoscopic surgery space expansion device, which comprises an expansion part 1, a traction rod 2 and a puncture part 3.
[0038] Among them, the expansion part 1 is in the shape of an opening, and one end of the expansion part 1 is an insertion end 11, and the other end is a connecting end 12. One end of the traction rod 2 is connected with the connecting end 12, and the traction rod 2 extends along the axial direction of the expansion part 1. The puncture part 3 is connected with the insertion end 11 to guide the expansion part 1 into the puncture hole.
[0039] Specifically, the expansion part 1 is hollow, and a plurality of through holes 4 are arranged on the expansion part 1, and the traction rod 2 is a pipe body, one end of the traction rod 2 communicates with the through hole 4, and the other end is a pipe opening.
[0040] Before the device is installed, a puncture hole is prepared on the patient, and a 10-ml syringe needle is used to perform a pre-puncture under the direct vision of the endoscope, and then the puncture part of the device is rotated and placed into the hole.
[0041] For example, when the device is used for auxiliary operation, the medical staff can use the puncture part 3 to enter the prepared puncture hole, and the insertion end 11 of the expansion part 1 is also synchronized to enter as the puncture part 3 enters. At this time, the traction rod 2 is pulled outward, the expansion part 1 pulls the tissue outward, and an operation space is formed. Then, the expansion part 1 is rotated to be parallel to the puncture hole, and the puncture part 3 is also rotated to be vertical during the rotation of the expansion part 1. The operation space formed by the expansion can avoid the needle of the puncture part 3 from scratching the internal tissue. The preliminary operation space can avoid the needle of the puncture part 3. After the expansion part 1 is rotated, the expansion part 1 is gradually rotated into the operation space. After the expansion part 1 completely enters the operation space, the traction rod 2 is further pulled, the anterior neck muscles are simultaneously pulled upward, the operation space is expanded, and thus the lesion part of the thyroid nodule is better exposed, the surgical field is widened, the operation is facilitated, and the operation space can be adjusted by lifting and pulling during the operation. The medical staff can adjust the exposure angle of the operation according to the actual needs, and the device has the advantage of high flexibility.
[0042] In addition, various electric surgical instruments are used in the operation space during the operation to separate tissues, coagulate and stop bleeding, etc. The tissue is incompletely burned to form smoke-like fine particles, and the particles have a visible burning smell. The through hole 4 can attract the particles into the external suction device. The influence of the smoke on the patient's body is reduced, the influence of the smoke on the endoscope lens of the surgeon is reduced, the frequency of lens cleaning is reduced, the surgical process is accelerated, and a safe and clear field of view is provided.

[0045] Through the arrangement of the structure, the puncture part 3 is in a vertical relationship with the expansion part 1, so that the needle of the puncture part 3 can point to the bottom of the operation space during the rotation of the expansion part 1 into the operation space. The expansion part 1 is rotated into the operation space, and the situation that the puncture part 3 scratches the tissue around the operation space during the rotation of the expansion part 1 into the operation space is avoided, and the overall operation safety is improved.

[0049] In an embodiment, a hook 23 is arranged at the top of the vertical section 22.
[0050] Specifically, the top of the vertical section 22 is bent to form the hook 23, after the position adjustment of the expansion part 1 is completed and the operation space is pulled to the required position, the overall position of the expansion device can be fixed by tying a fixing rope at the hook 23, which facilitates the fixation and suspension.

Then, the expansion part 1 is rotated to correspond to the parallel state of the puncture hole, and in the process of rotating the expansion part 1, the puncture part 3 is also rotated to the vertical state, and the operation space formed by expansion can avoid the needle of the puncture part 3 from scratching the internal tissue, and the initially formed operation space can avoid the needle of the puncture part 3;
[0052] After the expansion part 1 is rotated, the expansion part 1 is gradually rotated into the operation space, after the expansion part 1 completely enters the operation space, the traction rod 2 is further pulled to expand the operation space, so as to expose the lesion part of the thyroid nodule and widen the surgical field;
[0053] After the operation space is pulled to the required position, the overall position of the expansion device can be fixed by tying a fixing rope at the hook 23.
[0054] After the operation is completed, the expansion device can be disassembled and taken out by reverse operation.

[0057] Specifically, the puncture part 3 is in a diamond structure as a whole, and the end of the puncture part 3 is arranged in a taper, and the tapered end can realize the puncture effect.
[0058] Specifically, when the expansion device is used for auxiliary operation, the medical staff no longer needs to perform the perforation treatment in advance, and in the operation process, the tapered end of the puncture part 3 can be used to puncture the patient, and after the puncture is completed, the insertion end 11 of the expansion part 1 also enters synchronously, at this time, the traction rod 2 is pulled outward, the expansion part 1 pulls the tissue outward, and the operation space is formed by expansion, and then the expansion part 1 is rotated to correspond to the puncture hole in parallel, and in the process of rotating the expansion part 1, the puncture part 3 is also rotated to the vertical state synchronously, and the operation space formed by expansion can prevent the needle of the puncture part 3 from scratching the internal tissue, and the preliminary operation space can play a role in avoiding the needle of the puncture part 3. After the expansion part 1 is rotated, the expansion part 1 is gradually rotated into the operation space, and after the expansion part 1 completely enters the operation space, the traction rod 2 is further pulled, the anterior neck muscle is pulled upward at the same time, the operation space is expanded, so as to better expose the lesion part of the thyroid nodule and widen the operation field, and in the operation process, the operation space can be adjusted by lifting and pulling, the medical staff can adjust the exposure angle of the operation according to the actual needs, and the use flexibility is high.
