However, as mentioned above, the heat-sealing process of the specimen bag is a special process, and factors such as heat-sealing (welding) fixture errors, heat-sealing (welding) pressure errors, and heat-sealing (welding) temperature unevenness are strictly controlled, which leads to small batches of different specifications. The size of the specimen bag is very expensive, so far no individual or organization has proposed or provided a feasible customized product or solution for the specimen bag

The invention relates to a novel customized medical specimen bag. The novel customized medical specimen bag comprises a bag opening capable of being opened and closed and a bag body formed by extending from the bag opening, wherein the bag opening comprises a surrounding tunnel; the bag body further comprises a thin film bag face, a folded edge, a first double-faced adhesive bonding seam, a seconddouble-faced adhesive bonding seam, an inlet welding seam substantially parallel to the first double-faced adhesive bonding seam, a main body welding seam substantially parallel to the second double-faced adhesive bonding seam, and a tail welding seam; thin films are connected into a semi-closed bag-shaped whole comprising the bag opening through the folded edge, the inlet welding seam, the mainbody welding seam and the tail welding seam; and the inlet welding seam, the main body welding seam and the tail welding seam can be formed by multiple times of welding processing through the same welding mold and the same welding parameters.
Description
Technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to a new customized medical specimen bag. Background technique [0002] In minimally invasive surgery (especially rigid endoscopic surgery), it is usually necessary to remove internal tissues or diseased organs through a small incision in the patient's skin or through a puncture catheter. How to safely and conveniently remove tissues or diseased organs in the cavity has always been a problem that plagues minimally invasive surgery. Since the first clinical application of hard tube endoscopic surgery, a variety of special specimen bags for endoscopic surgery have been developed at home and abroad. Although the structure and use of the specimen bag are different, they can be divided into two categories: the first type, a single specimen bag. The United States invention patent US5037379 discloses a single-side open specimen bag with a string. When in use, the specimen bag needs ...
