An insertable anti-leaking ostomy device includes a tube having an internal end and an external end, and a first inflatable balloon positioned at or near the internal end. The device is configured to be inserted through a stoma into a patient's body, with the first inflatable balloon positioned inside the body and the external end remaining outside. After insertion, the first inflatable balloon is inflated via an inflation valve to retain the device beneath a fascial layer and to provide a sealed flow channel for effluent. In some embodiments, a second inflatable balloon is positioned at or near the external end to help funnel effluent into a normally attached ostomy pouch and reduce leakage. An applicator with a base and a plunger can facilitate insertion and deployment of the device.

This invention discloses an osteotomy guide plate, which includes a guide plate body, a first osteotomy blade groove, and a second osteotomy blade groove.

2.1. There are limitations to the function or benefit of surgical drains, for example, that the fluid can only be assessed after a sufficient quantity has been drained outwards. Furthermore, unintentional dislocation of the drains is common. For hygienic reasons, a dislocated drain cannot be reinserted into the body, and diagnostic or therapeutic instruments or substances cannot be introduced postoperatively through an already in place drain. The invention is intended to enable the postoperative insertion of instruments and / or agents, as well as repositioning, and to reduce the likelihood of dislocation. 2.2.The technical problem is solved by the invention being a drainage system or a tubing system that has a sterile channel which remains sterile even long after the drainage system or tubing system has been inserted and can be opened as needed to introduce diagnostic and / or therapeutic instruments and / or substances and / or to correct the position of the drainage system or tubing system. In addition, a particularly flexible section is provided at a distal end, which prevents accidental dislocation of a proximal end.

Manual insertion device has retraction spring (202) and hollow septum configuration (224) implemented using barrel-shaped guides (108, 110) and a guiding boss (210) in insertion device housing (106), and provides a fluid path through alignment of septum openings, side-port openings and catheter openings upon complete catheter insertion. Button (200) causes manual insertion of introducer needle (204) and catheter (220) of a first barrel (108) into a skin surface, and loading of retraction spring (202) disposed in an adjacent second barrel (110). Once introducer needle (204) and catheter (220) are fully inserted, the introducer needle hub (206) is released and automatically retracted by release of the retraction spring (202), leaving the catheter (220) in the user's body. Septums (218, 224) and side-port openings (216, 228) in the button (200) and introducer needle (204) are thus aligned, creating an uninterrupted fluid path between a reservoir or pump and catheter (220).

This invention relates to the field of medical device technology and discloses an abdominal wall suture device and method, comprising a pin, a trocar body, and a locator. The pin has an external through hole, and the locator includes an insert cannula that can be inserted into the pin and a tube seat at the head end of the insert cannula. The insert cannula has an internal through hole, and a positioning block is provided at the tail end of the insert cannula. This invention, by setting up a locator and utilizing a positioning block that conforms to the abdominal wall, positions the pin, ensuring that the trocar body accurately penetrates the fascia on both sides of the bottom of the channel when inserted obliquely along the pin, improving suturing efficiency and reducing errors. The clamping block on the positioning block holds the suture and flips it to the symmetrical other side of the channel, allowing the trocar body to quickly and efficiently clamp and pull out the suture after a second insertion. This allows for rapid and successful suturing without laparoscopy, significantly reducing operational difficulty and making it better suited for suturing the last channel in laparoscopic surgery.
