Abstract

The invention discloses an auxiliary device for minimally invasive surgery. The auxiliary device comprises a handle, a control part and a releasable grasping forceps part, wherein the grasping forcepspart is provided with two forceps arms which can move oppositely; inner anchoring magnets are further installed in the grasping forceps part, and are used for cooperating with external magnetic control equipment and a control part to realize clamping of tissue; a pickup magnet and a fastening mechanism are installed in the control part; and the pickup magnet and the inner anchoring magnets interact with each other, and cooperate with the fastening mechanism to further control connection and separation of the grasping forceps. The auxiliary device of the invention can facilitate operations ofa doctor on abdominal tissue, and reduces one opening number in comparison with traditional surgery; the fastening structure is employed to connect the grasping forceps stably to prevent the graspingforceps part from accidentally falling off; and meanwhile, with the cooperation of an external magnet, traction of a clamped part is more flexible, and positioning is more stable, so that the surgeryefficiency of a surgeon is greatly increased, the surgery difficulty is lowered, the risk of infection is lowered, and the pain of a patient is relieved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an auxiliary device that can be used for minimally invasive surgery. Background technique [0002] Minimally invasive surgery is a newly developed surgical method in recent years, and it is an inevitable trend in the development of future surgical methods. With the rapid development of laparoscopic technology and industrial manufacturing technology, many traditional open surgeries have been replaced by laparoscopic surgery, which greatly alleviates the patients' postoperative pain. [0003] Traditional laparoscopic surgery adopts two to four hole operation method, that is, several small incisions with a diameter of 5 to 12 mm are made in different parts of the abdomen. The surgeon operates various surgical instruments outside the body through these small incisions to complete the operation. During the operation, Organs are naturally hanging down. In order to fully expose the l...
