Description

Technical Field

[0001] The invention relates to medical equipment, in particular to a guidewire-guided puncture-type tracheal intubation device. Background Art

[0002] Tracheotomy Tracheotomy refers to the surgical method of opening the front wall of the trachea to establish an airway. It is an emergency measure to open the airway in clinical work under emergency conditions. It is quick and effective. It is mainly used for acute and chronic laryngeal obstruction caused by various reasons, such as laryngeal edema, diphtheria, etc.; dyspnea caused by retention of respiratory secretions; emergency airway medication; severe head and facial trauma, etc. However, tracheotomy still has the following defects in clinical application:

[0003] 1. Large wound. Tracheotomy is usually performed by cutting the skin and subcutaneous tissue along the midline of the anterior neck from the lower edge of the thyroid cartilage to the area near the suprasternal fossa, and the anterior tracheal tissue needs to be separated. This causes great trauma to the patient and easily leaves scars after surgery, affecting the appearance.

[0004] 1.2. The operation is difficult. Tracheotomy has certain requirements on the location and depth of the trachea and the technical level of the operator. Improper operation during the operation can easily cause complications, such as damage to the posterior wall of the trachea and the anterior wall of the esophagus, causing tracheoesophageal fistula.

[0005] The cricothyroid membrane is a layer of fibrous connective tissue membrane located between the thyroid cartilage and the cricoid cartilage. There is no hard cover in front, and the trachea is behind it. There are no vital parts around it, so it is easy to puncture. The puncture site is a soybean-sized depression 2 to 3 cm below the highest point of the Adam's apple. Medical personnel can perform the operation after training. Compared with tracheotomy, the operation is less difficult and causes less damage to the patient. It can be used as a pre-treatment for tracheotomy to buy time for the patient's subsequent emergency treatment.

[0006] At present, most of the cricothyroid membrane puncture items are simple assemblies, such as connecting an oxygen tube with a syringe needle, etc. There is no product that can perform tracheotomy and cannulation while puncturing the cricothyroid membrane and entering the trachea, and achieve a supporting effect on the main bronchus. Inspired by the guidewire-guided puncture and cannulation operation in vascular surgery, a device is provided to meet the above two requirements, which can not only meet the patient's adequate ventilation, but also reduce the damage of the operation and reduce the difficulty of the operation. Summary of the invention

[0036] The present invention is capable of various modifications and various embodiments, and therefore specific embodiments are illustrated and described in the accompanying drawings. However, this is not intended to limit the present invention to specific implementations, but should be understood to include all modifications, equivalents, and even substitutes that fall within the concept and technical scope of the present invention.

[0037] like Figure 1As shown, the present embodiment provides a guidewire-guided puncture-type tracheal / cricothyroid membrane puncture and catheter placement device, which can enter the trachea through the cricothyroid membrane puncture and then expand one or both main bronchi as needed, and comprises a puncture and catheter placement body 100 and a tracheal support member 200;

[0038] The puncture catheter body 100 is a hollow frame structure or a structure similar to a stent graft, and includes a first puncture catheter 110 and a second puncture catheter 120;

[0039] The first puncture tube 110 and the second puncture tube 120 have a common side portion, that is, they form a shape of two tubes connected by the side portions. Considering that the main bronchi are located on both sides of the tracheal tip, the connected part is in the upper half, and the lower half is a forked shape.

[0040] Considering that if the tube body is forked at the end at the beginning of the tube placement, it may cause the tube body to be inserted unsmoothly, therefore, the following designs are made for the forked tip in the present invention:

[0041] like Figure 2 As shown, the tails of the first puncture catheter and the second puncture catheter are not connected, and are made of a deformable material. The deformable material can be medical plastic, medical metal or a combination thereof (i.e., the main body of the tube is made of plastic material, and a metal strip is embedded in its length direction to increase its deformation hardness).

[0042] like Figure 3 As shown, the ends of the first puncture catheter and the second puncture catheter have adjustment rings;

[0043] One end of the adjusting member (generally a traction rope with toughness, etc.) is fixed on the adjusting ring, and the other end reaches the head end (i.e., the exit part outside the body) of the first puncture tube and the second puncture tube through the inner tube wall of the first puncture tube and the second puncture tube. During use, when the tip of the tube reaches the main bronchus, the tips of the first puncture tube and the second puncture tube can be bent at the required bending angle and amplitude by pulling the adjusting member at the head end, so as to fit the angle of the main bronchus.

[0044] Another design, such as Figure 4 As shown, the tails of the first puncture catheter and the second puncture catheter are made of elastic material and are naturally ejected in a Y-shape without external pressure.

[0045] In order to limit the Y-shaped tip to a closed state during the catheterization process, the ends of the first puncture catheter and the second puncture catheter are connected by an opening and closing piece, and the opening and closing piece is a T-shaped hanging piece, which is externally connected to the side where the first puncture catheter and the second puncture catheter are in contact;

[0046] The T-shaped hanging piece is installed on the outer tube wall of the first puncture tube and the second puncture tube, and has a through tube arranged up and down;

[0047] One end of the pop-up device is inserted into the through tube of the opening and closing piece to lock the relative positions of the first puncture tube and the second puncture tube. The head end is a hook-shaped device made of deformable material, which is just hung on the through tube below to achieve positioning. The other end passes through the entire tube wall of the first puncture tube and the second puncture tube and extends from the head end. During use, when the first puncture tube and the second puncture tube are both in place, the pop-up device is pulled with a little force from the head end to straighten the hook-shaped structure so that it can be detached from the through tube, thereby releasing the elasticity of the through tube to make it pop open in a Y shape, just docking with the main bronchus. Of course, if the position is slightly offset, positioning can also be achieved by pulling at the distal end.

[0048] The trachea support member 200 includes a first trachea support member 210 and a second trachea support member 220;

[0049] The first tracheal support member 210 is telescopically disposed in the first puncture tube 110 and has an expandable expansion portion 211 and a push rod 212;

[0050] The second tracheal support member 220 is telescopically disposed in the second puncture tube 120 and has an expandable expansion portion 221 and a push rod 222;

[0051] Under the action of the push rod, the expansion portion moves in and out of the first trachea support component and the second trachea support component.

[0052] The expansion part can be made of elastic material, and can be expanded in an umbrella shape without external pressure to form a supporting shape. The shape after the expansion part is expanded can be an umbrella shape, a spindle shape, or other shapes that can achieve support. Of course, the expanded shape can also be similar to the result of a vascular stent, and can be expanded through a ball valve / air valve and other devices. When the expansion part is subjected to external pressure (such as the action of pulling the push rod outward), it returns to its original state (i.e., is flattened), so that it can return to the puncture catheter, and then after the operation is completed, it can be removed from the body together with the puncture catheter.

[0053] Although the above description is centered on the embodiment, it is only an example and does not limit the present invention. It is clear to those skilled in the art that various modifications and applications not illustrated above can be made within the scope of the essential characteristics of the present embodiment. For example, each component specifically shown in the embodiment can be implemented after being modified. Moreover, various differences related to such modifications and applications should be interpreted as being included in the scope of the present invention as defined in the attached claims.
