Minimally invasive surgery specimen taking-out rod

Technical Field

The utility model belongs to the field of medical equipment, in particular to pole is got to minimal access surgery sample.

Background

Compared with the traditional operation mode, the minimally invasive surgery has small wound, light pain and quick recovery of patients, and is widely popularized in clinic. Tissue samples or surgical resection obtained during minimally invasive surgery are often taken out, and for this reason, various bags for recovering surgical specimens have been developed. The structure of these operation specimen bags generally includes two parts, namely a bag body and a handling rod: the bag body is usually made of a long conical water-proof textile or a high polymer material; the operating lever is typically made from an operating handle in combination with metal or plastic tubing. In the minimally invasive surgery process, the specimen bag is conveyed into a body through the instrument channel by operating the operating handle, a tissue specimen or surgical excision is put into the specimen bag, the bag is locked by operating the pull wire at the end of the operating handle, and the specimen bag is taken out through the instrument channel.

Patent publication No. CN208541385U discloses a surgical specimen fetching device, which comprises an outer tube, a fixed handle, a pull rod, a movable handle, a fetching bag and a pull rope, wherein the pull rod is connected with a fork-shaped elastic part consisting of a first elastic arm and a second elastic arm at the far end of the pull rod; when the operation specimen fetching device is in a first state, the bag opening of the fetching bag is opened; when the surgical specimen fetching device is in the second state, the tongue-shaped structure of the fetching bag is released from the fork-shaped elastic piece; when the operation specimen fetching device is in the third state, the bag opening of the fetching bag is closed. Although the device is simple to use, the fork-shaped elastic part can be flicked off suddenly in the extending process and is easy to hit the internal organs of a patient, and meanwhile, the process of inserting the fork-shaped elastic part into the fetching bag to be assembled together and then inserting the fork-shaped elastic part into the containing cavity of the pull rod is very time-consuming.
