Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an oral retractor for patients with head and neck tumors. Background Art

[0002] Head and neck tumors include oral cancer, thyroid cancer, nasopharyngeal cancer, malignant adenoma, osteosarcoma, etc. When treating thyroid cancer, transoral endoscopic thyroidectomy is usually adopted. Transoral endoscopic thyroidectomy is to make a small incision in the patient's oral cavity, then insert a retractor from the patient's surgical incision and extend it into the patient's neck, and then use the retractor to lift the patient's epidermal tissue. The doctor performs the operation in the space opened by the retractor.

[0003] However, due to the different neck lengths of different patients, and the length of the existing retractor cannot be adjusted, for patients with longer necks, sufficient visual field space cannot be guaranteed, which is not conducive to the operation. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide an oral retractor for patients with head and neck tumors, which can adjust the length of the retractor at the patient's neck, is applicable to different patients, can fully extend into the patient's neck and throat, ensure sufficient visual field space, and facilitate surgical operation.

[0005] The technical solution adopted by the utility model is as follows: An oral retractor for patients with head and neck tumors, including a retractor body, the retractor body includes a connecting portion and a first retracting portion that can extend into the throat at the patient's neck, and the first retracting portion is connected with a second retracting portion that can be adjusted in position along the length direction of the first retracting portion.

[0006] Compared with the prior art, the beneficial effect of the utility model lies in:

[0007] Since the second retracting portion of the utility model can be adjusted in position along the length direction of the first retracting portion, and the second retracting portion is connected with the first retracting portion, the sum of the lengths of the first retracting portion and the second retracting portion can be changed, that is, the position of the second retracting portion can be adjusted according to the patient's neck length, and then the sum of the lengths of the first retracting portion and the second retracting portion can be adjusted, so that the first retracting portion and the second retracting portion can cooperate to fully extend into the throat at the patient's neck. Then, when an external force pulls the connecting portion, the first retracting portion and the second retracting portion can be driven to move outward, and then the epidermal tissue at the patient's neck can be fully lifted, ensuring sufficient visual field space and facilitating surgical operation.

[0008] As a preferred embodiment of the present utility model, a groove is provided at one end of the first pulling part close to the second pulling part. A plurality of connecting grooves are symmetrically provided on a pair of opposite inner side walls of the groove and are spaced apart along the length direction of the first pulling part. The second pulling part includes a support block and symmetrically arranged connecting bars. One end of each of the two connecting bars is connected to the support block. The connecting bars are elastic. A connecting column that can be snapped into the connecting groove is provided at one end of each of the two connecting bars away from the support block. The outer side surface of the connecting bar can be attached to the inner side wall of the groove.

[0009] In this solution, hold the two connecting bars with your hand and apply inward force with your fingers, so that the two connecting bars move closer inward. The connecting columns are located in the groove. Move the connecting bars along the length direction of the first pulling part and stop at a suitable position. The connecting columns on the connecting bars are snapped into the corresponding connecting grooves. While the position of the second pulling part moves, it is also stably connected to the first pulling part.

[0010] Beneficial effects: The groove can accommodate the two connecting bars. The cooperation of the connecting grooves and the connecting columns can not only make the position of the second pulling part move, but also ensure the connection between the second pulling part and the first pulling part.

[0011] As a preferred embodiment of the present utility model, anti-slip stripes are provided on the outer surface of the connecting column, the inner surface of the connecting groove, the outer surface of the connecting bar, and the inner surface of the groove.

[0012] Beneficial effects: It increases the stability of the connection between the connecting column and the connecting groove, increases the friction between the connecting bar and the groove, and prevents the connecting bar from sliding relative to the groove.

[0013] As a preferred embodiment of the present utility model, a compression spring is provided between one ends of the two connecting bars away from the support block.

[0014] Beneficial effects: The compression spring can ensure that the two connecting bars are always relatively separated, ensure that the connecting columns are always located in the connecting grooves, and increase the stability of the connection between the connecting columns and the connecting grooves.

[0015] As a preferred embodiment of the present utility model, a plurality of connecting columns are arranged at intervals along the length direction of each connecting bar.

[0016] Beneficial effects: It can increase the stability of the connection between the connecting bar and the groove, that is, increase the stability of the connection between the first pulling part and the second pulling part.

[0017] As a preferred embodiment of the present utility model, the inner surface of the bottom of the connecting column and the connecting groove are magnetically attracted to each other.

[0018] Beneficial effects: It can increase the stability of the connection between the connecting bar and the groove, that is, increase the stability of the connection between the first pulling part and the second pulling part. Description of the Drawings
