specific Embodiment approach

[0010] figure 1 , the device is divided into an internal part (anastomotic part), a conducting part, and an extracorporeal part (control part). The body part consists of a part of 1, 2 and 3. The conduction part is composed of 3,4. The in vitro part consists of 5,6,7. 1 is a disc-like structure with a small hole in the center and a raised edge, which is the part where the force acts. 2 is a device for anastomosis with the esophagus paired with 1, which has a central bulge on the other side, and is the action point of 4, with a central small hole and a local ring-shaped bulge to prevent slippage. 3 is to pull a practical thin medical stainless steel guide wire through 1 and then weld an anti-slip device. 4 is a hose with a metal skeleton, which can transmit the force of the external part to the device 2. 5. It is an internal thread external sleeve 6. Externally threaded hollow screw matched with 5, with auxiliary force handle. 7 is a metal buckle device that prevents slipp...

Abstract

The invention discloses an esophageal extension and anastomat capable of being accurately controlled in vitro, and belongs to the field of medical instruments. The esophageal extension and anastomat is divided into an in-vivo part (anastomosis), a conduction part and an in-vitro part (control part); the anastomosis part is divided into two disc shaped structures, the conduction part is composed ofa hollow metal soft catheter and an internal steel wire, the control part can accurately control the extension length to be in the millimeter level, force is conducted to the anastomat through the conduction part, and the effects of gradual slow controllable esophageal extension and squeezing anastomosis can be achieved. The esophageal extension and anastomat can be extended and anastomosed, hasan extension function and an anastomosis function, and can overcome the defects that an existing anastomat cannot be extended, and the extension strength, the extension distance and the like cannot beaccurately controlled.

Description

technical field [0001] The invention belongs to the field of medical technology, and belongs to the category of medical instruments. Background technique [0002] Congenital esophageal atresia and esophagotracheal fistula are the most common and serious deformities in esophageal dysplasia. Esophageal lengthening technology is mainly used in the treatment of congenital esophageal atresia with long-segment deletion, and esophageal strictures caused by various reasons such as chemical burns, surgery, trauma, and tumors. At present, there are certain difficulties in the treatment of esophageal stenosis. The current treatment techniques include: surgical resection and anastomosis, surgical suture traction, magnetic force extension and compression technology, intestinal tube replacement of esophagus surgery, but each method has certain limitations and shortcomings. Surgical resection and anastomosis: It is mainly suitable for normal esophageal anastomosis, which is usually within...
