Abstract
An external trachea bracket is made of biodegradable material-polylactic acid material which can be absorbed by human body, and comprises two transverse rods and a plurality of connecting rods arranged between the two transverse rods. During operation, the outer tracheal stent is placed in a thoracic cavity at a trachea collapse part or is attached to the outer wall of a trachea; then the two ends of the outer tracheal stent are fixed at the healthy part of the human body, the middle section of the outer tracheal stent is fixed with the trachea collapse part so as to lift the trachea collapse part, and the outer tracheal stent is left in the human body and is gradually absorbed along with the time. The trachea outer support has simple structure and extremely convenient operation, can avoid various problems caused by the inner support, can meet the individual requirements of people with different physical constitutions, and has extremely high applicability.
Description
Technical Field
The utility model relates to the field of medical appliances, in particular to an outer tracheal stent for treating tracheitis.
Background
The trachea softening is a pathological phenomenon that the trachea lacks due cartilage hardness and supporting force to cause different degrees of collapse of the lumen. An endotracheal stent, i.e., a stent arranged inside a trachea-collapse part for supporting, is a common treatment means. However, the endotracheal stent has many problems, for example, mass production of the endotracheal stent cannot accurately meet individual requirements of stenotic trachea, cannot meet the requirements of continuous growth and development of stenotic trachea of children patients, and has a phenomenon of oppressing edema tissues around the trachea after operation, and in addition, various complications such as endotracheal injury, granulosis and the like are easily caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a set up in outside trachea support of trachea to satisfy different patients' individuation needs, eliminate all kinds of problems that the endotracheal inner support brought, and improve the convenience of operation.
The utility model relates to an outer trachea bracket, which comprises two adjacent transverse rods, wherein a plurality of connecting rods are arranged between the adjacent sides of the two transverse rods at intervals along the direction of the transverse rods; the transverse rod and the connecting rod can be deformed and are made of biodegradable materials.
The outer trachea bracket, the transverse rod and the connecting rod are all made of polylactic acid materials.
The outer trachea bracket of the utility model, the two transverse rods and the connecting rod between the two transverse rods jointly form a structure similar to the shape of a ladder stand, and the two transverse rods and the connecting rod are made of biodegradable materials, namely polylactic acid materials, which can be absorbed by human bodies. When the tracheomalacia operation is carried out, the length of the outer tracheal stent can be cut according to the specific condition of a patient, such as the circumference of a trachea, and the outer tracheal stent is shaped into a long shape, a U shape or a ring shape after being heated; then the orthopedic and proper-size outer tracheal stent is placed at the trachea collapse part of the patient; then, carrying out intermittent sewing on different parts of the collapsed tracheal wall and the tracheal outer bracket, such as 3-4 needles for sewing, so as to lift the tracheal collapsed part; thereby increasing the ventilation cross section of the softened trachea, completing the treatment operation of the softened trachea, and the outer tracheal stent is remained in the human body and is gradually absorbed along with the time. The trachea outer support has simple structure, is very easy to suture with the trachea, and is very convenient and fast to operate; and it is placed outside the trachea, can avoid various problems that the inner support causes; in addition, the trachea outer support can meet individual requirements of people with different physical constitutions, and has extremely high applicability; meanwhile, the polylactic acid material has the deformation capacity, can be softened after being soaked in water at about 75 ℃, can be changed into a proper shape according to the needs of a patient, and can be solidified after being cooled if being corrected into the proper shape according to the outer diameter of the trachea, so that the applicability and the operation convenience of the material are greatly improved.

Detailed Description
An outer trachea bracket comprises two adjacent transverse rods 1, wherein a plurality of connecting rods 2 are arranged between the adjacent sides of the two transverse rods at intervals along the direction of the transverse rods; the transverse rod and the connecting rod can be deformed and are made of biodegradable materials.
The outer trachea bracket, the transverse rod and the connecting rod are all made of polylactic acid materials.
The trachea outer support is characterized in that the two transverse rods 1 are arranged in parallel, the distance between the two transverse rods is 5mm, and the diameters of the transverse rods and the connecting rods are 0.8 mm.
As shown in figure 1, the two transverse rods and the connecting rod between the two transverse rods form a structure similar to a ladder stand, and the transverse rods and the connecting rod are all made of biodegradable materials, namely polylactic acid materials, which can be absorbed by human bodies. When the tracheostomy operation is carried out, the length of the outer tracheal stent can be cut according to the specific condition of a patient, such as the circumference of a trachea, and the outer tracheal stent is shaped into a long shape, a U shape or a ring shape after being heated, as shown in figure 2; then, placing the orthopedic and proper-sized outer tracheal stent at the trachea collapse part of the patient, as shown in fig. 3, wherein P is the cross section of the softened trachea; then, performing intermittent suturing on different parts of the collapsed tracheal wall and the tracheal outer bracket, such as 3-4 needles, so as to lift the tracheal collapsed part, as shown in fig. 4, wherein F is a suture line; thereby increasing the ventilation cross section of the softened trachea, completing the treatment operation of the softened trachea, and the outer tracheal stent is remained in the human body and is gradually absorbed along with the time.
