Description

Technical Field

[0001] This application relates to medical devices, and more particularly, to a retractor for endoscopic thyroidectomy via the infraclavicular approach. Background Art

[0002] Traditional open thyroidectomy requires a low collar transverse arc incision in the neck, resulting in postoperative neck scar hyperplasia and anterior cervical region dysfunction, which not only affects aesthetics but also troubles the patient's life. With the update of endoscopic surgical methods and the continuous progress of instruments, scarless surgeries in the neck have gradually emerged, and various approaches to endoscopic thyroidectomy have appeared, such as the total areola approach, axillary approach, oral vestibule approach, infraclavicular approach, etc.

[0003] In recent years, endoscopic single-port thyroidectomy via the infraclavicular approach has been reported successively. In this procedure, an axillary retractor is used to lift the epidermal tissue from the patient's infraclavicular region to the neck. The Chinese utility model patent with the publication number CN213641009U discloses an axillary retractor for endoscopic thyroidectomy, which shows very good practicability in axillary approach endoscopic thyroidectomy. However, when this retractor is used in endoscopic thyroidectomy via the infraclavicular approach, the following problems will occur: First, the surgical path of endoscopic thyroidectomy via the infraclavicular approach is significantly shorter than that via the axillary approach, and half of this retractor will be exposed outside the incision, and the exposed part will significantly block the mobility of surgical instruments in the vertical direction. Second, fixing the suction device under the retractor occupies the surgical operation space, restricting the operation of surgical instruments and the surgical field of view. Third, the starting end of the retractor is a flat mouth, which is prone to slipping during the operation of lifting the skin, affecting the smooth progress of the operation.

[0018] See Figure 1 As shown, the subclavian approach endoscopic thyroid surgery retractor 100 according to an embodiment of this application mainly consists of a pull rod 10, a suspension hook part 20, a lifting part 30 and a suction device 40. The suspension hook part 20 is bent from one end of the pull rod 10 towards one side of the pull rod 10, the lifting part 30 is bent from the other end of the pull rod 10 towards the other side of the pull rod 10 that is opposite to the said one side, and the suction device 40 is fixedly arranged on the lifting part 30. In this way, the whole retractor 100 is generally in an S shape.

[0019] Specifically see Figure 1 As shown, the suspension hook part 20 of the retractor 100 includes a suspension arc segment 21 and a suspension segment 22. The suspension arc segment 21 is bent from one end of the pull rod 10 to form an arc, and the suspension segment 22 extends linearly from the end of the suspension arc segment 21. Moreover, the opening width L from the end of the suspension segment 22 to the pull rod 10 is set to be less than or equal to the opening width D of the suspension arc segment 21, so that when the suspension hook part 20 of the retractor 100 cooperates with the suspension system in the operating room, it is not easy to disengage.

[0020] See again Figure 1 As shown, the lifting part 30 of the retractor 100 includes a lifting arc segment 31, a lifting segment 32 and an anti-slip tail segment 33. The lifting arc segment 31 is bent from the other end of the pull rod 10 that is opposite to the suspension hook part 20 to form an arc, the lifting segment 32 extends linearly from the end of the lifting arc segment 31, and the anti-slip tail segment 33 is formed at the end of the lifting segment 32. Figure 1 In the shown embodiment, the anti-slip tail segment 33 is provided with an arch structure 331 that protrudes towards the inner side opposite to the pull rod 10 relative to the lifting segment 32, and the end 332 of the anti-slip tail segment 33 tilts towards the inner side to form an anti-slip structure to prevent the lifting part 30 from slipping during the process of lifting the human skin tissue. In different embodiments of this application, the anti-slip tail segment 33 can have one or more of the above-mentioned arch structures 331 that are smoothly connected, and the end 332 of the anti-slip tail segment 33 after the last arch structure 331 tilts towards the inner side.

[0021] See again Figure 1 As shown, the suction device 40 includes a suction tube 41 and a suction connector 42. The suction tube 41 has a first section 411 and a second section 412, and a through suction channel 413 is opened in the first section 411 and the second section 412 of the suction tube 41. Specifically see Figure 1As shown in the figure, the first section 411 of the suction tube 41 is fixedly connected to the inner side of the lifting section 32 of the lifting part 30 by a connection method such as welding. The second section 412 of the suction tube 41 passes through the lifting arc section 31 of the lifting part 30 and then extends obliquely. The suction connector 42 is connected to the end of the second section 412 of the suction tube 41. An air suction opening 414 that penetrates the peripheral wall toward the lifting section 32 is formed at the end of the suction channel 413 in the first section 411 of the suction tube 41. At least one air suction hole 321 that penetrates the inner and outer sides is provided on the lifting section 32 opposite to the air suction opening 414. The suction connector 42 is used to connect to an external suction device. The suction connector 42 is designed with an opening that gradually narrows from the inner end connected to the suction tube 41 to the outer end, so that the smoke generated during the operation can be discharged in time through the air suction hole 321, the air suction buckle 414, and the suction channel 413. Further refer to Figure 1 As shown in the figure, the suction tube 41 of the suction device 40 is fixed to the inner side of the lifting section 32 of the lifting part 30 according to the above-mentioned embodiment of the present application for a semi-hidden design. Moreover, the height h of each arched structure 331 that protrudes inward of the anti-slip tail section 33 of the lifting part 30 does not exceed the outer circumference of the first section 411 of the suction tube 41 fixedly connected to the inner side of the lifting section 32. The angle θ at which the end 332 of the anti-slip tail section 33 tilts inward is less than or equal to 45°, and the height H also does not exceed the outer circumference of the first section 411 of the suction tube 41. This will be more conducive to the placement of the lifting part 30 of the retractor 100.

[0022] Refer to Figure 2 As shown in the figure, the specific implementation process of the subclavian approach endoscopic thyroidectomy retractor 100 according to the above-mentioned embodiment of the present application is as follows: First, the surgeon designs an incision at the natural fold of the subclavian skin 60 of the patient. After opening the incision, the subcutaneous tissue is separated, the skin flap is separated along the surface of the pectoralis major fascia, and the dissection continues along the clavicle and the clavicular end of the sternocleidomastoid muscle. Subsequently, the lifting part 30 of the retractor 100 is placed between the subclavian incision position and the dissected skin flap to establish an operation space 70. Then, the suspension hook part 20 of the retractor 100 is installed and fixed to the suspension system 50, and the suction connector 42 is connected to a negative pressure device to keep the operation space in a negative pressure state continuously, ensuring that the smoke generated during the operation is discharged in time. Subsequently, the surgeon uses endoscopic instruments 80 to remove the lesion site 90 of the patient, irrigate the wound surface, place a negative pressure drainage, and finally suture the subclavian incision.

[0023] The subclavian approach endoscopic thyroidectomy retractor 100 according to the above-mentioned embodiment of the present application has the following several advantages:

[0024] 1. The retractor 100 adopts an S-shaped design and is provided with an anti-slip arched structure 331 at the anti-slip tail section 33 of the lifting part 30. It can not only provide a vertically upward pulling force to ensure the operation space, but also provide a lateral pulling force to pull and fix the skin tissue, preventing the skin tissue from being unhooked. The smoothly connected anti-slip tail section 33 can also reduce the damage to the tissue during the lifting process;

[0025] 2. The retractor 100 fixes the suction tube 41 of the suction device 40 inside the lifting section 32 of the lifting part 30 for a semi-hidden design. After the lifting part 30 lifts the tissue, the suction tube 41 is on the side of the human skin and does not occupy the lower surgical operation space, making the vertical cavity building height higher and more conducive to the operation of surgical instruments;

[0026] 3. The retractor 100 keeps a distance between the suction opening 414 of the suction tube 41 and the suction hole 321 correspondingly opened in the lifting part 30 and the end 331 of the lifting part 30 to ensure that the suction hole 321 and the suction opening 414 will not be blocked after the retractor 100 lifts the tissue;

[0027] 4. The suction connection head of the suction device 40 adopts a design in which the opening gradually shrinks from the inner end connected to the suction tube 41 to the outer end, making full use of the principle of aerodynamics to accelerate the air flow velocity and timely discharge the smoke generated during the surgical operation to ensure the clarity of the surgical operation field of view;

[0028] 5. The length of the lifting part 30 of the retractor 100 can be designed to be basically the same as the length of the subclavian approach path to ensure that the retractor 100 will not be exposed too much after being inserted and affect the movement of surgical instruments in the vertical direction.

[0029] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
