Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to an I-shaped hypopharyngeal support laryngoscope. Background Art

[0002] Currently, in the field of otolaryngology and head and neck surgery, the use of the da Vinci surgical robot to remove oropharyngeal and parapharyngeal space tumors has become the gold standard for minimally invasive resection of oropharyngeal cancer and parapharyngeal space tumors. It can not only accurately remove tumors to achieve a satisfactory survival rate, but also avoid the huge trauma caused by traditional surgeries such as mandibular incision and reduce damage to surrounding important blood vessels and nerves, significantly improving the patient's quality of life after surgery.

[0003] However, in practice, due to the tumor's deep laryngeal location, existing openers, such as the Davis tonsil opener, are unable to adequately expose the surgical cavity. A common clinical solution is to use an epiglottis or hypopharyngoscope to expose the surgical cavity. The robotic endoscopic arm, leveraging the endoscope's angle, observes from the side of the epiglottis (outside the cavity), while another robotic operating arm extends from within the epiglottis to perform the procedure. Alternatively, the robotic endoscopic arm and the laryngoscopic arm can swap positions.

[0004] However, due to the limitations of the human oral space, this method cannot allow the two robotic arms of the surgical robot to reach the surgical cavity at the same time to perform operations, so optimization and improvement are needed. Utility Model Content

[0008] The handle portion is fixedly provided on the upper side of the upper plate body, and the endoscope tube and the suction tube are fixedly provided on the lower side of the upper plate body.

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

For example, they can refer to fixed or detachable connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0021] like Figure 1-Figure 3 The laryngoscope shown is an I-shaped hypopharyngeal support laryngoscope, which includes a handle portion 1, a main body portion 2, an endoscope tube 3 and a suction tube 4.

[0022] The main body 2 includes an upper plate 5, a lower plate 6 and a connecting plate 7. The upper plate 5 and the lower plate 6 are arranged opposite to each other, and the connecting plate 7 is vertically connected between the upper plate 5 and the lower plate 6 to form an I-shaped main body 2. The rear end of the upper plate 5 extends backward beyond the lower plate 6 and bends upward.

[0023] The upper side of the upper plate 5 is fixed with a handle 1. Figure 2 As shown, the lower end of the handle portion 1 is fixedly connected to the upper plate body 5, and the upper end of the handle portion 1 first extends obliquely forward and upward, and then bends and extends obliquely backward and upward, thereby facilitating the operation and use of the laryngoscope.

[0024] An endoscope tube 3 and a suction tube 4 are fixedly provided on the lower side of the upper plate 5, and both the endoscope tube 3 and the suction tube 4 extend along the upper plate 5 and are also bent upwards. Figure 1 As shown, the endoscope tube 3 is arranged on the upper side of the connecting plate 7, and the suction tube 4 is arranged beside the endoscope tube 3.

[0025] Specifically, the laryngoscope has the following structural features:

[0026] 1. Based on the anatomical characteristics of the oral cavity and laryngeal cavity, the upper plate 5 of the laryngoscope main body 2 is designed to be curved and tilted upward. Therefore, when in use, the laryngoscope can easily pass through the oral cavity to reach the hypopharynx, tongue root, epiglottis, etc., thereby easily exposing the hypopharynx, tongue root, epiglottis, etc. while opening the oral cavity;

[0027] 2. The main body 2 is made into an I-shape, which can separate the left and right cavity spaces, so that the two robotic arms of the surgical robot can reach the surgical cavity through different cavity spaces at the same time to perform operations;

[0028] 3. A dedicated endoscope tube 3 is provided as an endoscope channel, which can free up the operating space of the cavities on both sides to the greatest extent and avoid hindering the operation of the surgical robot's mechanical arm;

[0029] 4. A special suction tube 4 is provided. When the suction tube 4 is connected to an external negative pressure system, negative pressure can be generated to facilitate the removal of smoke generated by electrocautery cutting during surgery.

[0030] In summary, the I-shaped hypopharyngeal support laryngoscope in this scheme can easily expose the hypopharynx, tongue root, epiglottis and other parts. It is equipped with a dedicated endoscope channel to maximize the operating space on both sides of the I-shape, so that the two robotic arms of the surgical robot can simultaneously extend into and reach the surgical cavity for operation.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
