Description

A kind of single hole is through stomach wall through stomach wall Intragastric surgery device

Technical field

The utility model belongs to medical instruments field, is related to a kind of single hole through stomach wall through stomach wall Intragastric surgery device.

Background technique

In recent years, with the fast development of the universal endoscopic technic of gastrocopy, the prognosis such as early carcinoma of stomach, Gastric stromal tumors are good The diagnosis of good stomach neoplasm gradually rises.Existing technique of surgical treatment mainly stresses the treatment of advanced gastric carcinoma, therefore is based on Existing technique of surgical treatment and the surgical instrument designed cannot fully meet the requirement of disease treatment.Early carcinoma of stomach stomach function regulating Mesenchymoma is the indication of minimally-invasive treatment, and therefore, the raising of these disease early diagnostic rates has pushed the minimally invasive new skill of surgical intervention The development of art and new instrument.It through stomach wall Intragastric surgery is one of the new surgical technique emerged in large numbers in recent years, the technology handle through stomach wall Surgery is directly protruding into gastral cavity with laparoscopic surgical instruments and lens of laparoscope, directly observation stomach inner disease foci, and can be sharp simultaneously It is performed the operation and is cut off in gastral cavity expert with surgical instrument.

Conventional laparoscopic technology cannot observe directly early carcinoma of stomach lesion and part is located at subserous mesenchymoma lesion, It is difficult to carry out to prepare positioning in art and determines lesion boundary；And conventional laparoscopic technology excision extension is larger, for being located at cardia Or the lesion near pylorus, widened excision extension will lead to the damage of cardia or pylorus peristaltic function, seriously affect the postoperative of patient Quality of life.Lift-off technology can directly observe gastric mucosa lesion under gastric mucosa under scope, can also go endoscopic lesion resection, But the technology is larger to the lesion operation difficulty for being located at cardia and stomach bottom, and the complication such as perforation, bleeding easily occur.Single hole warp Stomach wall compensates for the deficiency of conventional laparoscopic operation and endoscopic technic through stomach wall Intragastric surgery technology, is particularly suitable for being located at stomach The excision of lesion under the mucous membranes such as the early carcinoma of stomach of middle and upper part rear wall and Gastric stromal tumors and mucous membrane.

Committed step through stomach wall through stomach wall Intragastric surgery is the foundation of operation path, is lacked in ideal gastral cavity at present Surgical instrument casing, molding single hole are more rare through stomach wall Intragastric surgery device through stomach wall.Involved in the utility model A kind of single hole solves through stomach wall Intragastric surgery device through stomach wall and is difficult to fixed stomach through stomach wall Intragastric surgery casing through stomach wall The problem of wall, and complicated surgical procedures are realized by single hole, it is a kind of operation device highly promoted and applied.
