Problems solved by technology

[0003] At present, when performing transoral thyroid surgery, two medical staff are required to pull both sides of the patient's lower lip with plate-like retractors on both sides of the bed to expose the cavity and facilitate the operation. However, the operation of multiple medical staff occupies a large surgical space. , and maintaining the same movement for a long time will consume a lot of physical strength for the medical staff, and the pulling force of the two people is likely to be different when pulling, resulting in poor exposure of the cavity, which is not conducive to the operation

Embodiment 1

[0034] A cavity retractor for endoscopic thyroidectomy, comprising a mounting plate 1, two sets of mounting plates 1 are vertically arranged, the two sets of mounting plates 1 are symmetrically arranged, and the bottoms of the two sets of mounting plates 1 are fixedly connected with electric telescopic Rod 2, the two sets of electric telescopic rods 2 are fixedly connected with C-shaped clamps 3 on the opposite side, and the two sets of mounting plates 1 are also horizontally connected with a rotating rod 4, and the two ends of the rotating rod 4 respectively pass through the two sets of mounting plates 1. The rod body of the rotating rod 4 located between the mounting plates 1 is a rectangular rod body, and the rotating rod 4 is provided with an adjustment mechanism.

[0035] In addition, the adjustment mechanism includes two sets of adjustment assemblies symmetrically arranged on the rotating rod 4. The adjustment assembly includes a casing 5, a sliding cylinder 6, a first-st...

Embodiment 2

[0041] A cavity retractor for laparoscopic thyroidectomy, on the basis of the first embodiment, the pulling mechanism includes a connecting plate 13, a T-shaped screw 14, an elastic member 15, a secondary threaded cylinder 16, and a connecting rod 17 And pulling hook 18, connecting plate 13 is vertically fixedly connected to the bottom of fixing plate 8, secondary threaded barrel 16 is threaded on T-shaped screw rod 14, T-shaped screw rod 14 ends are connected with connecting plate 13 in rotation, 15 sets of elastic parts It is arranged on the T-shaped screw rod 14 and its two ends bear against the connecting plate 13 and the secondary threaded barrel 16 respectively.

[0042]In addition, there are two groups of connecting rods 17, two groups of connecting rods 17 are arranged parallel to the secondary threaded barrel 16 and symmetrically fixedly connected to the secondary threaded barrel 16, two groups of connecting rods 17 are slidably connected with the connecting plate 13 a...

Abstract

The invention discloses a cavity access endoscope thyroid resection lacuna tractor, and relates to the field of surgical instruments. According to the scheme, the device comprises two sets of mounting plates, the two sets of mounting plates are symmetrically arranged, electric telescopic rods are fixedly connected to the bottoms of the two sets of mounting plates, a rotating rod is further horizontally and rotationally connected between the two sets of mounting plates, an adjusting mechanism is arranged on the rotating rod, and the adjusting mechanism is matched with a traction mechanism used for traction of the lower lip valve exposed lacuna of a patient. The traction device has the beneficial effects that by arranging the adjusting mechanism, it is guaranteed that the two sets of traction hooks act synchronously, the traction effect is improved, and meanwhile the problem that the operation space occupied by multiple manual traction is large is solved; the traction mechanism is arranged for traction through a mechanical structure, it can be guaranteed that the traction force is roughly the same, the cavity gap exposure effect is improved, and the situation that the cavity gap exposure effect is poor due to the fact that multiple workers cooperate for traction, and the traction force is different is avoided.

Description

technical field [0001] The invention relates to the field of surgical equipment, in particular to a cavity tractor for laparoscopic thyroidectomy. Background technique [0002] The full name of transoral thyroid surgery is transoral vestibular thyroid surgery, which refers to thyroid surgery through the oral vestibular (between the teeth and lips) approach. Because the oral mucosa does not leave scars after healing, it belongs to the thyroid surgery of the natural cavity of the human body. The subcutaneous tunnel trauma is relatively small, the lymph nodes in the central neck area are cleaned conveniently and thoroughly, and no scars are left after healing. Etc. [0003] At present, when performing transoral thyroid surgery, two medical staff are required to pull both sides of the patient's lower lip with plate-like retractors on both sides of the bed to expose the cavity and facilitate the operation. However, the operation of multiple medical staff occupies a large surgica...
