This invention relates to the field of medical devices, and particularly to a novel tracheostomy occlusion device, comprising an operating table, a fixation plate, an adjustment mechanism, and an execution mechanism. This invention addresses the following problems encountered in the practical use of tracheostomy auxiliary retraction devices: prolonged holding of the retractor by the surgical assistant can cause soreness and lead to shaking of the retractor, which in turn can cause neck movement, affecting the normal progress of the surgery and potentially causing further trauma to the patient's trachea. Furthermore, it cannot effectively manage blood flowing from the neck, which may lead to blood entering the trachea and causing respiratory discomfort, even threatening the patient's life; the portion of the tracheostomy cannula inside the trachea obstructs the airway, affecting the patient's ability to cough up sputum and leading to inaccurate assessments of the patient's coughing ability; and it can easily cause blind sinus tracts to form at the tracheostomy site.

This invention belongs to the field of traditional Chinese medicine external preparation technology, specifically providing a traditional Chinese medicine ointment for treating chronic osteomyelitis, bone tuberculosis, and persistent sinus tracts, as well as its preparation method. The traditional Chinese medicine ointment provided by this invention comprises 3-10 parts of *Achyranthes bidentata*, 5-15 parts of dried ginger, 0.3-1 part of red mercury sulfate, 20-50 parts of calcined gypsum, 4-12 parts of gecko, 5-15 parts of buffalo hide, and 40-100 parts of medicinal ointment base. This invention selects *Achyranthes bidentata*, red mercury sulfate, calcined gypsum, gecko, dried ginger, and buffalo hide as the main ingredients, achieving a combination of warming and cooling properties, and a tonifying and purging effect. It can effectively clear deep pus, necrotic tissue, and dead bone, while also warming and unblocking meridians, improving local blood circulation, promoting wound healing, and reducing the irritation of the medication.

This utility model discloses a multifunctional measuring and recording ruler for wound undermining and sinus tracts. It includes a right-angle measuring ruler with connecting measuring rulers fixed at both ends, and a movable measuring ruler at the end of the connecting measuring ruler furthest from the right-angle measuring ruler. It also includes a movable sleeve connected to the top of the right-angle measuring ruler, with a colored pen inside the sleeve. This multifunctional measuring and recording ruler for wound undermining and sinus tracts allows for precise measurement of wound undermining and sinus tracts within the patient's wound using the right-angle measuring ruler, movable measuring ruler, and connecting measuring ruler. When wound depth needs to be measured, the ruler is held vertically, and one end of the movable measuring ruler is inserted into the wound to measure the depth. The depth is then marked with a colored pen according to the different depths of the wound, allowing for accurate and convenient recording of wound undermining and sinus tract size and depth, providing a basis for scientific wound assessment and treatment adjustments.

The invention discloses an application of regulating and controlling a Notch / Wnt signal channel in blocking formation of hidradenitis suppurativa active sinus tracts, and further discloses an application of regulating and controlling the Notch / Wnt signal channel in screening a medicine for blocking formation of the hidradenitis suppurativa active sinus tracts. The screening is realized by detecting the influence of a candidate substance on the activity of the Notch / Wnt signaling pathway. The influence on the activity of the Notch / Wnt signal path comprises activation of the Notch signal path and / or inhibition of the Wnt signal path. According to the invention, the S0 epithelial cell subgroup and a molecular marker combination (such as COL4A1, LAMC2, ITGA6, MMP1 and the like) specifically expressed by the S0 epithelial cell subgroup are identified, and the key regulation function of a Notch / Wnt signal channel in the subgroup is defined, so that a clear direction and a target spot are provided for deeply researching a molecular mechanism formed by a sinus tract; and a key theoretical basis and a feasible technical path are provided for subsequent establishment of a targeted drug screening system and discovery of effective candidate substances.
