Description

Technical Field

[0001] The present invention relates to the technical field related to medical devices, and in particular to a device for assisting tracheal U-shaped incision. Background Art

[0002] Tracheotomy is a surgical procedure that involves cutting open the cervical trachea and inserting a metal tracheal tube or a silicone tube. It is mainly used to relieve dyspnea caused by laryngeal origin, respiratory dysfunction or retention of lower respiratory tract secretions.

[0003] At present, ordinary pointed blades are routinely used for tracheotomy. The diameter of the trachea is not convenient for inserting the cannula. If the diameter of the tracheotomy is too small, it is easy to cause difficulty in inserting the cannula, and if it is too large, it is easy to cause postoperative complications. After the tracheotomy, an assistant is required to open the incision to facilitate the insertion of the cannula. However, if the cooperation is not skilled during this process, it will make it difficult to insert the tracheotomy cannula and waste operation time. Patients who need tracheotomy are often in critical condition and need timely ventilation. Once the outlet tube has been removed but the tracheotomy cannula is difficult to insert, the patient is in danger of life. Summary of the invention

[0009] Furthermore, the tail end of the suction rod is rotatably mounted on a connecting block, the connecting block is rotatably mounted on the adjusting arm, and a magnet is arranged on the mounting rod to adsorb the suction rod.

[0010] Furthermore, the cutter includes a sliding seat, a knob, a mounting block and a blade. The sliding seat is slidably mounted on the U-shaped ring, the knob is rotatably mounted on the upper end of the sliding seat, the mounting block is slidably inserted into the lower end of the sliding seat, and the blade is detachably mounted on the mounting block. The mounting block is controlled to slide up and down by turning the knob, thereby driving the blade to slide up and down.

[0011] Furthermore, a one-way screw is rotatably installed inside the lower end of the sliding seat, and the mounting block is threadedly sleeved on the one-way screw. Spur gears are fixedly installed at the lower end of the knob and the upper end of the one-way screw, and a transmission rod is rotatably installed in the sliding seat.

[0016] 2. The present invention slides support rods on both sides of the U-shaped ring on the adjusting arm, and rotatably sets a bidirectional screw rod inside the adjusting arm. By rotating the bidirectional screw rod, the support plates on the two support rods can be driven to move backwards, so that the skin tissue above the trachea is stretched to expose the trachea, which is convenient for cutting the tracheal incision.
