Stomach lifting device

Abstract

The invention provides a stomach lifting device which is used for laparoscopic surgery. The stomach lifting device comprises a net-shaped stomach supporting part, an outer frame and a plurality of puncture needles, wherein the net-shaped stomach supporting part is formed by weaving flexible materials; the outer frame is arranged on the periphery of the stomach supporting part, and a plurality of storage handles are arranged on the outer frame; the puncture needles are in one-to-one correspondence with the storage handles, are connected with the outer frame or the storage handles through connecting wires, can be stored in the storage handles and can be taken out when used; and the stomach lifting device can be curled and can be automatically unfolded without external force. The stomach lifting device is provided with needles and threads, after the stomach lifting device is placed in the abdominal cavity, the puncture needles can be directly taken out of the storage handles to be used, and therefore the needles do not need to be threaded temporarily. The puncture needles are stored in the storage handles, the connecting wires are prevented from being knotted, and the situation that the puncture needles are arranged in advance and consequently the puncture needles easily prick a patient is avoided. The friction force between the net-shaped stomach supporting part formed by weaving the flexible materials and the stomach is large, and the stomach can be prevented from moving in the surgery.

Description

technical field [0001] The invention relates to an instrument for abdominal surgery, more specifically, relates to a surgical instrument for lifting the stomach body in laparoscopic surgery to facilitate intraoperative operation on the stomach or its rear organs. Background technique [0002] Gastric cancer is one of the common malignant tumors of the digestive tract, and its incidence is increasing year by year. The number of laparoscopic radical gastric cancer operations is increasing year by year. Since the stomach itself is relatively flexible and will move accordingly, it is extremely difficult to operate on the lower side of the gastric body. Gently lift the body of the stomach and fix the surgical instruments that expand the operative field. Due to the large weight and special shape of the stomach body, the existing similar lifting devices are not effective. Therefore, it is an urgent problem to be solved at present to provide a laparoscopic lifting device specially...

Problems solved by technology

[0003] At the same time, in the existing scheme, when the lifting device is used to lift the stomach, uterus, etc., no needle thread is set on the lifting device, and the needle is temporarily threaded after the lifting device is put into the abdominal cavity. Because the existing lifting device is put into the abdominal cavity first when used, and then the doctor manually unfolds the lifting device in the abdominal cavity. In this process, if the needle and thread are set on the lifting device in advance, Then multiple needles are very easy to pierce the patient during the manual deployment of the lifting device

However, through temporary on-site needle threading, on the one hand, it is necessary to reserve pinholes on the lifting device, resulting in a complicated structure of the lifting device; thus prolonging the operation time
