Description

Medical Aids Technology

 The present invention relates to a medical aid, and more particularly, to a medical aid suitable for fixing a body so as to be suitable for the examination or surgery at the time of examination or surgery of a body such as a breast.

 Akita

Background art

 2. Description of the Related Art Conventionally, there has been known an apparatus for fixing a breast by sandwiching the breast between two plates in order to fix a breast when performing mammography (mammography using a lentogen) in order to inspect a breast cancer or the like.

 In addition, when a part of the tissue was cut off from the breast, the breast was directly fixed by hand during the biopsy for examination.

 When performing an examination or surgery using an endoscope in the abdominal cavity, use a tracker to inject carbon dioxide, laughter, or air into the abdominal cavity to secure a viewing space or operation space. Open the cavity (pneumoperitoneum), make a small incision in the abdominal wall, and laparoscopic surgery. There is also known a method in which a balloon is inserted into the abdominal cavity and air is supplied to the balloon (air sac method). A method is also known in which a needle or hook is passed through the skin and the space is secured by lifting it (lifting method).

Disclosure of the invention

 However, a device that fixes the breast with a plate is very painful because the breast is deformed into an unnatural shape.

When manually fixing the breast, it is difficult to firmly secure the entire breast without deforming it. During a biopsy, temporarily fix the breast with a plate In this case, the needle is not able to pass through because the sandwiching plate is hard, and the route for passing the biopsy needle when collecting tumor tissue in the mammary gland is considerably narrow and limited.

 Pneumoperitoneum (1) promotes cancer progression, (2) exacerbates liver damage, (3) cools and dries the abdominal cavity and tissues, (4) blood circulation (5) When carbon dioxide gas is injected, the concentration of carbon dioxide in the blood rises, and it is necessary to regulate the artificial respiratory organs, and at the same time, the carbon dioxide gas diffuses inside the tissue and may destroy the tissue. Yes, there are problems.

 The lifting method is (1) easy to destroy the skin or subcutaneous tissue (only a small part of the skin can be lifted), (2) small viewing space or operating space to lift a part of the skin, (3) May cause bleeding. (4) When injecting eczema into abdominal skin or subcutaneous tissue, the intestinal tract (gastrointestinal tract) may also penetrate. (5) Flexible and changeable lifting position There are problems such as being unable to do so.

 The present invention has been made in view of the above problems, and provides a medical aid suitable for fixing a body so as to be suitable for examination and surgery without damaging the body during examination or surgery of a body such as a breast. With the goal.

 The medical aid of the present invention is flexible and sucks and holds the skin.

 In addition, since silicone rubber is used as a main component, the adhesiveness to the skin is high. When used, the skin and its peripheral portion can be lifted and fixed by adhering to the skin and adsorbing the skin.

 In addition, since there is a traction section on the top, it can be easily lifted with a simple configuration.

 In addition, by having a ridge ring near the inner opening, it is possible to enhance traction and function for a long time.

In addition, since there are multiple convex ridges, the interior is partitioned into multiple spaces, so that when the suction function falls and it falls off, it does not fall off suddenly, but in steps. As they fall off gradually, unexpected situations can be avoided. In addition, because it is transparent, even if the suction function falls off and falls off, the situation can be visually recognized from the outside beforehand and the situation can be dealt with.

 Further, since the vicinity of the opening is thicker than other portions, the elasticity can be increased and the suction force can be enhanced.

 In addition, a suction mechanism that maintains a low pressure for suction at the top enables stable towing for a long time.

 In addition, since the suction mechanism has a cylinder and a piston, it does not need power, so that there is no electric wiring and maintenance is easy.

 Further, since the cylinder has a stopper for preventing the piston from falling off, it is possible to prevent the piston from falling off the cylinder.

 In addition, by having a projection around the through hole for suction, the through hole is prevented from being blocked by the skin, and stable towing can be performed for a long time.

 Further, the medical aid of the present invention wraps and fixes the breast.

 In addition, by using silicone rubber as a main component, X-rays, lines of magnetic force, ultrasonic waves, and the like can be efficiently transmitted, and even if a small needle or the like is pierced, the function of rapidly aspirating is not lost.

 Also, since the top is flat, the shoulder can be made thicker than the other parts to increase the strength.

 In addition, by suction-fixing the breast, the tissue in the breast can be fixed, and when a biopsy needle for removing the tissue is inserted, the tumor does not escape easily and the needle is easily applied to the tumor.

In addition, because it is transparent, skin marks, objects and objects can be visually recognized from the outside. This description includes part or all of the contents as disclosed in the description and / or drawings of Japanese Patent Application No. 2001-309692, which is a priority document of the present application.
