Description

A hemostatic device for clinical operations in general surgery

technical field

The utility model relates to the technical field of medical instruments, in particular to a hemostatic device for clinical operations in general surgery.

Background technique

With the extensive development of Western medicine all over the world, surgical operations have gradually become common, ranging from internal organ resection and transplantation to small external traumas. The most important part of surgery is to stop bleeding. The patient loses a large amount of blood, and the blood in the human body is limited. A large amount of blood loss will lead to a decrease in the oxygen transport capacity of the human body, and even endanger the patient's life.

According to the patent number CN215228049U, published (announcement) date 2021.12.21, a hemostatic device for general surgery clinical operation is disclosed, which includes a concave tube, and both sides of the concave tube are provided with holes for binding the concave tube to the The bandage on the affected part of the patient, the notch of the concave tube faces the wound of the patient, the two side walls of the notch of the concave tube are mutually symmetrical slopes, and the two slopes of the concave tube are equally spaced. A plurality of chutes, each of which is slidably provided with sliders, the upper and lower sides of each of the sliders are fixedly installed with limit blocks for limiting the relative position of the sliders, each of the bottom The bottom of the limit block is fixedly installed with a pressing rod arranged on the side of the patient's wound. The device is provided with a plurality of pressing rods by sliding along the chute at the bottom of the concave tube, and the device realizes the deviation of the pressing rods along the direction of the chute after being compressed by binding the concave tubes on both sides of the patient's affected part. At this time, the pressure rod can drive the wounds on both sides of the affected area to squeeze each other closer to avoid continuous leakage of blood. The excellent hemostatic effect of the device is more conducive to the recovery of the patient's affected area.

The most commonly used hemostatic equipment in surgery is hemostatic forceps and tourniquets, which deform blood vessels by compressing them to achieve the purpose of hemostasis. For some small operations involving only a few blood vessels, hemostatic forceps are inconvenient to use, and The tourniquet will compress the blood vessels on the surface of the entire limb during use, and blocking the blood flow for a long time will cause discomfort to the patient and even affect the patient's health.
