Problems solved by technology

[0004] However, at present, the hemostatic clips used under the existing flexible endoscope are all magnetic. When the hemostatic clip is in the body, MRI examination cannot be done, and a warning sound will be issued when passing the security check, because the metal part of the hemostatic clip retained in the body is magnetic. The reason has brought a lot of inconvenience to patients who have used the product

Abstract

The invention relates to the technical field of medical instruments, and discloses a non-magnetic hemostatic clip used in cooperation with an endoscope, the non-magnetic hemostatic clip comprises a clamping part and a release part, the clamping part comprises two clamping pieces and a clamp tube, the two clamping pieces are arranged in the clamp tube, the release part comprises a handle, a sliding handle is arranged on the handle in a sliding mode, a mandrel is fixedly connected to the sliding handle, and the mandrel is fixedly connected with the handle. The end, away from the sliding handle, of the mandrel is fixedly connected with a connecting piece, the mandrel is sleeved with a spring hose, one end of the spring hose is fixedly connected with the handle, the other end of the spring hose is fixedly connected with a rotating piece, and the end, away from the spring hose, of the rotating piece is detachably connected with the clamp tube. One end, far away from the mandrel, of the connecting piece is detachably connected with the two clamping pieces; the clamping piece and the clamp tube are made of non-magnetic materials or non-magnetic absorbable materials. The device can be repeatedly opened and closed, is simple and reliable in structure, is convenient to release, is moderate in clamping force, is non-magnetic in a remaining body, and does not need to worry about the influence of magnetic resonance and the alarm trouble of a security check instrument.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a non-magnetic hemostatic clip used in conjunction with an endoscope. Background technique [0002] With the development of endoscopic technology and other related technologies, endoscopic hemostasis has become the first choice for the treatment of gastrointestinal bleeding. Currently commonly used endoscopic hemostasis methods include laser coagulation, electrocoagulation, local injection of drugs to stop bleeding, drug spraying and hemostatic clip clamping. Among them, hemostatic clip clipping method has become the most effective non-surgical treatment of gastrointestinal bleeding due to its characteristics of small trauma, fast hemostasis, low incidence of rebleeding, few complications, and definite curative effect. . The clip will naturally fall off as the wound heals, and it takes one to two weeks for the general tissue wound to heal. In 4 weeks, there are eve...
