Abstract
The utility model provides a combined artificial esophagus made of Ni-Ti memory alloy, which is formed by a tubular Ni-Ti alloy net, of which the inner wall is provided with silica gel intima, and of which both ends are bell-shaped; polyester braided connecting rings are provided that are close to both ends of the Ni-Ti alloy net. The utility model is able to be effectively connected to the broken end of the esophagus, and to combine with the ''revitalized esophagus'' to form a permanently implanted part of the reconstructed esophageal channel and a support to the ''revitalized esophagus'' to ensure smoothness. Being adaptable to the human esophageal reconstruction, the utility model has solved the key problems causing failures in the study of artificial esophagus such as anastomotic fistula, stricture of artificial esophagus or ''revitalized esophagus'', incompatibility between the artificial esophagus and ''revitalized esophagus'' that causes shedding and shift of the artificial esophagus.
Description
Technical field
This utility model relates to the artificial succedaneum of a kind of medical science organ, refers in particular to a kind of Ultimum Ti combined type artificial esophagus
Background technology
The most effective treatment way of esophageal benign and malignant malignant tumor is to adopt surgical resection pathological changes esophagus, and simultaneously damaged esophagus is carried out esophageal reconstruction to recover food passageway.Current main material as esophageal reconstruction is: coincide and recover the esophagus passage carrying thoracic cavity or cervical region and reservation normal esophageal on autologous tissue's organ such as stomach, the intestinal.But there is following shortcoming in this traditional modus operandi: operation wound is big, operating time is long, the transition of mobile organ anatomical position are to the influence of cardio-pulmonary function, and the digestive tract physiological function disorder that causes thus etc.For this reason, seek a kind of simple and practically, can be used for clinical esophagus succedaneum (or claim artificial esophagus) is one of focus of medical circle research as the esophageal reconstruction material always.
The research direction of current artificial esophagus has two kinds, and the one, develop a kind of what is called " permanent artificial esophagus " that can forever implant also and can be combined as a whole with " newborn esophagus ".The 2nd, develop a kind of support effect that only temporarily plays, the what is called " impermanency artificial esophagus " that finally can degrade voluntarily and disappear or after body " newborn esophagus " substitutes, need to treat the taking-up or the discharge that comes off voluntarily.No matter be permanent or the Several Key Problems used in vivo of impermanency artificial esophagus: (1) esophagus broken ends of fractured bone is connected with artificial esophagus; (2) artificial esophagus narrow or " newborn esophagus " narrow; (3) artificial esophagus come off the displacement etc.The fistula of operative incision that occurs in the experiment, late period, artificial esophagus or " newborn esophagus " were narrow, and artificial esophagus displacement comes off and causes obstruction, complication such as hemorrhage, finally causes the failure of an experiment.
Summary of the invention
The purpose of this utility model is to provide a kind of a kind of Ultimum Ti combined type artificial esophagus that can not cause phenomenons such as fistula of operative incision, artificial esophagus is narrow, artificial esophagus comes off.
For achieving the above object, this utility model has been taked following technical scheme: a kind of Ultimum Ti combined type artificial esophagus is to be provided with the silica gel inner membrance at tubulose Nitinol net inwall, its two ends flue; On close end place, two of Nitinol net outer wall, be provided with the terylene woven connecting ring.
The utility model has the advantages that: it can do effectively to be connected with the esophagus broken ends of fractured bone, and being combined into one with " newborn esophagus " becomes the part of permanent implanted intravital reconstruction esophagus passage, plays the supporting role to " newborn esophagus " simultaneously, guarantees that esophagus is unobstructed.Solved the current fistula of operative incision that causes artificial esophagus research failure, artificial esophagus narrow or " newborn esophagus " narrow, the key issue that the incompatible artificial esophagus that causes with " newborn esophagus " of artificial esophagus comes off and is shifted.
Description of drawings
Fig. 1 is wherein a kind of structural representation of specific embodiment of this utility model.
Among the figure: Nitinol net 1 silica gel inner membrance 2 terylene woven connecting rings 3
The specific embodiment
Below in conjunction with accompanying drawing this utility model is done to describe further.
As shown in Figure 1, Ultimum Ti combined type artificial esophagus of the present utility model is to be provided with silica gel inner membrance 2 at tubulose Nitinol net 1 inwall, its two ends flue; On close end place, two of Nitinol net 1 outer wall, be provided with terylene woven connecting ring 3.
When this utility model is specifically used, select one with the pathological changes esophagus bore that has excised, Ultimum Ti combined type artificial esophagus that length matches, two ends horn mouth terylene woven connecting ring 3 Outboard Sections of artificial esophagus are implanted respectively in esophagus two broken ends of fractured bone tube chambers of reservation, with the terylene woven connecting ring sutured of esophagus broken ends of fractured bone edge and artificial esophagus appearance, the reconstruction of finishing the esophagus passage at last connects then.
Claims (1)
