Embodiment 1

[0025] In the retractor for rhinoplasty endoscope in this embodiment, the fixed plate 1 is an arched plate, and the preparation method of the fixed plate can be: 1) bending the two long sides of the rectangular plate downward to form an arch; Raw materials are injection molded; 3) Cut the cylinder along the cylinder wall, and take part of the arc-shaped wall. The length of the arched fixing plate is 3.5-10cm, more preferably 5-8.5cm, more preferably 6-8cm, such as 6.5cm, 7cm, 7.5cm.

[0026] It also includes a first circular tube 2 and a second circular tube 3, which are respectively used as an endoscope tube and a flushing injection tube.

[0027] Install the first round tube 2 and the second round tube 3 in parallel in the arch groove of the fixed plate, and parallel to the fixed plate 1, wherein the second round tube 3 is a metal tube, and the length is greater than the length of the first round tube 1 ,Such as figure 1 As shown, both ends of the second round tube 3 excee...

Embodiment 2

[0032] In order to stabilize the insertion length of the endoscope, on the basis of Embodiment 1, the retractor of the rhinoplasty endoscope for nose surgery in this embodiment also includes a holding plate 4, and there is a holding plate 4 between the holding plate 4 and the fixing plate 1. Angle, such as figure 1 As shown, the included angle can be 90°, but it can also be other angles, depending on the included angle between the mirror body and the handle of the nasal endoscope.

[0033] The holding plate 4 is an arched plate, and the arch groove faces away from the fixing plate 1, and a fixing belt may also be provided to fix the endoscope.

[0034] The top of the holding plate 4 is also provided with a forward flat plate 41 (such as a tongue-shaped flat plate protruding forward), forming an inverted L shape, and the holding plate 4 is perpendicular to the flat plate 41 . The flat plate 41 contains a connecting port or a connecting part connected with the automatic pulling...

Embodiment 3

[0036] On the basis of Embodiment 1, in this embodiment, the second circular tube 3 protrudes from the arch groove of the fixing plate at the end provided with the baffle plate, and a cylindrical fixing member 5 is connected to the end protruding from the arch groove, so The above-mentioned cylinder means that the inside is a cylinder, and the external shape is not limited, and may be prismatic or cylindrical. Mainly used to connect and fix injection devices.

[0037] There may also be one or two wing plates 51 arranged on the outer side of the fixing member 5, but there may also be more than one. When there are two wing plates 51, the two wing plates 51 are arranged symmetrically, which is convenient to hold by hand and facilitates operation.

Abstract

The invention provides a retractor of a rhinoplastic endoscope for nasal surgery. The retractor of the rhinoplastic endoscope comprises a long fixed plate. A first round tube and a second round tube facing to the same direction are disposed on the fixed plate. An endoscope probe penetrates through the first round tube, a cleaning injector is connected with the second round tube, and accordingly the nasal surgery can be performed visually. The problem that the nasal surgery can be performed only in blind state or half-blind state at present is solved, and the retractor is applicable to surgical treatments such as nasal plastic beauty and subcutaneous tumor resection.

Description

technical field [0001] The invention relates to a surgical tool, in particular to an auxiliary tool for performing surgical operations in the department of rhinology. Background technique [0002] Rhinoplasty is currently a very popular plastic surgery project. There are two approaches for rhinoplasty surgery: intranasal approach and extranasal approach. Intranasal approach, nasal bone cone and cartilage cone nose surgery are very popular in foreign countries. [0003] Compared with the external nasal approach, the advantages of the intranasal approach are: less damage to the tissue, natural results can be obtained in a short time, no incision marks will be left on the exposed part of the external nose, and postoperative deformation is small. Moreover, with the application of endoscopic technology, the problem of surgical field of view can be solved theoretically. [0004] However, at present, in the specific operation process of the intranasal approach, the whole process ...
