A detachable ERCP-specific multifunctional biliary stone extraction balloon, which relates to the technical field of medical appliances, including a tube body, a joint and a balloon; a first balloon cavity, a first guide wire cavity and a first Injection cavity, the second balloon cavity, the second guide wire cavity and the second injection cavity are arranged in the second tube; one end of the first tube is provided with a first connector; one end of the second tube is provided with a second connector, The second connecting piece is connected with a hollow balloon column, a hollow guide wire column and a hollow injection column, an airflow inlet and an airflow outlet are arranged on the balloon column, and a one-way valve is connected in the balloon column; the second connecting piece and the first A connector is detachably connected. After the connection, the first balloon cavity, the first guide wire cavity, and the first injection cavity are arranged in one-to-one correspondence with the one-way valve, the guide wire post, and the injection post. The invention not only has the function of taking stones by the common biliary tract stone removal balloon, but also can be used as a guiding device, which reduces the risk of ERCP operation and improves the work efficiency.

The invention discloses a transnasal laryngeal mask which comprises a cuff, a ventilation catheter, an inflation pipe and an indication saccule, wherein the opening at the front end of the ventilating catheter is of an incline, the cuff is fixed around the front end of the ventilating catheter, the cuff is shaped as a flat spheroid under the inflation state, a diaphragm is arranged in the cuff and is provided with a small hole, one end of the inflation pipe is communicated with the cuff, and the indication saccule is connected to the inflation pipe. The cuff and the ventilation catheter form a ventilation device, the ventilation device is implanted through the inferior nasal meatus of a patient without being implanted into the oral cavity of the patient, thus the problem of difficulties of managing the oral cavity and fixing the position in the prior art is solved, the problem of poor tolerance of the common laryngeal mask under light anaesthesia is solved, and the safety of using the laryngeal mask is improved. The invention can help a patient suffering from epistaxis carry out nasal cavity hemostasis by compression, and solves the problems of nasal cavity hemostasis and incapability of ensuring smooth nasal cavity.

The invention discloses a cervical dilation saccule. The cervical dilation saccule comprises a hollow catheter, the catheter comprises a first hollow tube, and one end of the first hollow tube is welded with a second hollow tube; the diameter of the second hollow tube is less than that of the first hollow tube, one end of a second hollow catheter, near the first hollow tube is sleeved with a thermal shrinkage ring, and one end of the second hollow tube, away from the first hollow tube is provided with an air inflation head; two sides of the top end of the air inflation head are both provided with salient points, through holes are equidistantly formed in the outer wall of the air inflation head, a silicone saccule sleeves the hollow catheter through the second hollow tube, and one end of the air inflation head, away from the second hollow tube is adhered to a probe. The cervical dilation saccule is simple in structure, liquid or gas can be injected to the silicone saccule, so that the silicone saccule can change from small to big to slowly squeeze the cervical, the problem of insertion for many times can be solved, doctors' labor intensity can be reduced, operation time can be reduced, and patients' pain can be reduced.
