Problems solved by technology

[0006] At present, there is no comprehensive treatment device for the non-inflatable and scar-free treatment of the thyroid gland. Most of them are underarm or open surgery. At the same time, doctors and patients also hope to have a clear and intuitive understanding of the different effects before and after surgery.

Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0027] Such as figure 2 , image 3 , Figure 4 The assembly drawing shown: a non-inflatable thyroid retractor, including a duct 10 for guiding the discharge of smoke, a base plate 20 attached to the duct 10 as a whole, a vertical plate 30 connected to the top of the base plate 20, and a vertical plate 30 from the vertical plate 30 The lifting plate 40 is bent and extended sideways. The base plate 20 is provided with a chute 11 parallel to the guide tube 10. A pair of rotatable main retracting blades are symmetrically installed on both sides of the chute 11 away from the end of the vertical plate 30. 50 and a pair of secondary retracting blades 60, a pair of primary retracting blades 50 and a pair of secondary retracting blades 60 are constructed and designed to be moved eccentrically by the main push-pull rod 51 and the secondary push-pull rod 61 that slide linearl...

Abstract

The invention discloses an inflation-free thyroid retractor. The retractor includes guide pipes for guiding smoke exhaust, a base plate, a vertical plate connected to the base plate, and a pull platebent downward from the vertical plate; a slide groove is arranged in the base plate, a pair of rotatable main retractor blades and a pair of auxiliary retractor blades are symmetrically installed on two sides of the slide groove, the pair of main retractor blades and the pair of auxiliary retractor blades are constructed and designed to be shifted and eccentrically rotated along a main push-pull rod and an auxiliary push-pull rod that slide linearly along the slide groove, respectively, and the main push-pull rod and the auxiliary push-pull rod are respectively connected to a No.1 claw of a main transmission rod and a No.2 claw of an auxiliary transmission rod; and the main transmission rod and the auxiliary transmission rod pass through one end of a positioning sleeve fixed on the vertical plate and are only in coupled connection with a first rotary knob and the second rotary knob sleeving the positioning sleeve respectively, the first rotary knob and the second rotary knob are axially limited on the positioning sleeve and can rotate around the positioning sleeve to drive the main transmission rod and the auxiliary transmission rod to move linearly, so that the pair of main retractor blades and the pair of auxiliary retractor blades are mutually closed or opened. The inflation-free thyroid retractor is used for implementation of thyroid endoscopic surgery.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically relates to a non-inflatable thyroid retractor, which is especially suitable for various thyroid diseases. [0002] technical background [0003] Traditional laparoscopic thyroid surgery needs to open a tunnel from the areola in front of the chest and free the anterior neck and upper chest skin flaps. The incision is far away from the lesion and there is no natural cavity, so it is necessary to separate the subcutaneous tissue of the neck and chest in a large area and fill it with CO 2 The gas builds up the operating space, resulting in CO 2 It is absorbed into the blood through the wound surface, and at the same time, it is more difficult to remove and remove large tumors. [0004] Since 2003, as reported in "Laparoscopic Thyroid Surgery via the Subclavian Approach. Chinese Journal of General Surgery. April 2006" no inflation is required, but retractors are required...
