Problems solved by technology

Because the lymph nodes are behind the trachea, the trachea blocks the operation of surgical instruments, so that the lymph nodes in this area are not exposed enough, which is easy to damage the recurrent laryngeal nerve and increase surgical bleeding; and the lymph nodes in this area are also the most likely place for tumor metastasis. recurrence, resulting in failure of surgical treatment
[0003] In the prior art, there is no tracheal retractor specially used under thoracoscopy. When cleaning the paratracheal lymph nodes, the "five-leaf claw-shaped retractor" and "suction device" are usually used to pull the trachea. However, the existing devices, In actual use, it usually compresses the tracheal membrane, which not only causes insufficient exposure of lymph nodes, resulting in incomplete cleaning, but also easily causes tracheal damage and increases surgical trauma for patients.

Embodiment 1

[0048] See figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 as well as Image 6 As shown, this embodiment provides a tracheal 301 retractor 101 for use under thoracoscopy, including a retractor 101 and a traction rod 201. The retractor 101 is disposed at one end of the traction rod 201, and the retractor 101 is a spiral sheet structure. The angle between the central axis of the draw hook 101 and the central axis of the traction rod 201 is less than or equal to 45 degrees.

[0049] Because the shape of the trachea 301 is similar to a cylinder, the retractor 101 with a spiral sheet structure can better wrap and pull the trachea 301, which can effectively avoid damage to the trachea 301 and the recurrent laryngeal nerve, reduce surgical bleeding, and at the same time facilitate full exposure of the left recurrent laryngeal nerve. The paraneural lymph nodes, the 5th and 7th groups of lymph nodes make the lymph node dissection at this site more thorough, greatly reduce the diffi...

Embodiment 2

[0057] The main difference between this embodiment 2 and the above-mentioned embodiment 1 is that the tracheal 301 retractor 101 used under the thoracoscopy provided in this embodiment also includes an adjustment mechanism, which includes a rotating cap 401, a screw 402, a nut 403, and teeth. The bar 404, the first gear 405, the second gear 406, the third gear 407 and the transmission rod 408, of which,

[0058] Such as Image 6 , Picture 8 As shown, the traction rod 201 includes a first end 412 and a second end 413. The first end 412 is provided with a ring-shaped groove 410 and a first central hole 414, and the second end 413 is provided with a second central hole 415. A central hole 414 and the second central hole 415 communicate with each other through the first sliding groove 416;

[0059] The rotating cap 401 is arranged at the first end 412 and is clamped in the annular groove 410, such as Image 6 As shown, the rotating cap 401 can be rotated relative to the traction rod 2...

Abstract

The invention relates to a tracheal tenaculum used under a thoracoscope. The tracheal tenaculum comprises a tenaculum body and a traction rod; the tenaculum body is arranged at one end of the tractionrod and is of a spiral sheet structure, and the included angle between the center axis of the tenaculum body and the center axis of the traction rod is smaller than or equal to 45 degrees. The tracheal tenaculum is compact in structure and reasonable in design, and the lymphonodi at the rear portion of the trachea can be sufficiently exposed, so that lymphadenectomy is thorougher; meanwhile, theleft recurrent laryngeal nerve can be better protected, bleeding is reduced, the lymphadenectomy difficulty is greatly lowered, and application and popularization of the minimally invasive technologyfor conducting esophagectomy under the thoracoscope are facilitated.

Description

Technical field [0001] The invention relates to the technical field of endoscopic surgical instruments, in particular to a tracheal retractor used under thoracoscopy. Background technique [0002] At present, video-assisted thoracoscopic minimally invasive techniques are widely used in esophageal cancer operations in large hospitals. One of the technical difficulties of this operation is to clean the paratracheal lymph nodes (ie, the paratracheal lymph nodes). Because the lymph nodes are behind the trachea, the trachea blocks the operation of the surgical instruments, which makes the lymph nodes in this area not fully exposed, which easily damages the recurrent laryngeal nerve and increases surgical bleeding; and the lymph nodes are also the most easily metastatic location of the tumor. If the tumor is not completely cleaned, it will be easy Recurrence, leading to failure of surgical treatment. [0003] In the prior art, there is no tracheal retractor specifically used under thora...
