Problems solved by technology

[0003] The purpose of the present invention is to design a device that can effectively position the isolation net and prevent it from moving during the operation without manual intervention, aiming at the problem that the existing surgical isolator cannot be positioned and still needs to be manually pressed to prevent its displacement. An intrabody dilator that is easy to use and adjust, can greatly improve operation efficiency, and shorten operation time

Embodiment 1

[0020] Such as figure 1 shown.

[0021] A dilator in a body cavity, which is mainly composed of a metal mesh 1 with a medical polymer coating layer and a supporting structure 2, the metal mesh 1 can be folded or bent and deformed to a desired shape and maintained, and at the same time It can also be restored to its original state again. One end of the support structure 2 is connected to the metal mesh 1, and the other end is fixed on the hook plate, the main frame or the operating bed of the surgical retractor. It can support the metal mesh 1 to resist the isolation. The thrust produced by the tissue displaces the metal mesh. The metal mesh 1 can be braided by metal wires, stamped from metal sheets, or assembled and connected by metal mesh units. The metal mesh 1 is steel alloy, aluminum alloy or titanium alloy, and has plastic deformation, can be manually folded or bent in any direction, and its state after deformation can be retained in memory, and can be folded and bent m...

Embodiment 2

[0025] Such as figure 2 shown.

[0026] The difference between the present embodiment and the first embodiment is the difference of the support structure. The support structure of the present embodiment is that the support part 201 of the mesh body is only the two opposite metal sides, and the rest is exactly the same as the first embodiment.

Abstract

An intracavity dilator is characterized by mainly comprising a metal mesh (1) with a polymer coating and a support structure (2); the metal mesh (1) can be optionally deformed to a required shape sustainable, by folding or bending, and can be restored to the original shape; one end of the support structure (2) is connected with the metal mesh (1); the other end of the support structure (2) is fixed to a hook plate of a surgical retractor, a main frame of the surgical retractor or an operating bed; the support structure (2) is capable of supporting the metal mesh (1) to resist a thrust which displaces the metal mesh and which is produced by isolating tissues. The intracavity dilator is simple in structure, low in cost and convenient to manufacture and use and is capable of protecting soft tissues and organs and providing a good view during surgery.

Description

technical field [0001] The present invention relates to a medical device, especially one used for covering, isolating and protecting the organs around the operation surface during surgery, such as liver and gallbladder, gastrointestinal tract, omentum, heart and lung, etc., so as to expose the surgical field of view well, The utility model relates to a surgical instrument that is beneficial to a doctor's precise surgical operation, specifically a dilator in a body cavity. Background technique [0002] At present, when surgeons perform surgery in the body cavity, the operating surface is often blocked or covered by the surrounding organs and tissues, which affects the operation. One or two assistants are required to hold a hook plate or extend their hands into the body cavity to isolate or separate these organs or tissues , leaving enough space for the operating surface. For example, when performing bile duct surgery, it is necessary to block the liver in front of the bi...
