Description

Take compression function's peritoneoscope sample remove device

Technical Field

The utility model belongs to the technical field of medical equipment, and particularly relates to a laparoscopic specimen taking-out device with a compression function.

Background

With the development of endoscope technology and the continuous push of advanced minimally invasive surgical instruments, minimally invasive surgical procedures have been widely popularized. The surgical operation under the endoscope has certain space limitation, and the specially designed surgical specimen taking bag is used for taking out tissue specimens and surgical resections under the minimally invasive surgical scene and is widely applied to various minimally invasive surgeries.

Surgical specimen retrieval bags for use with tissue specimen and surgical resection retrieval devices are generally of two designs: one with a lever and the other without a lever. The bag body is generally made of long tapered water-proof fiber or polymer material; the lever is typically made of an operating handle in combination with a metal or plastic tubing. In the minimally invasive surgery process, a specimen bag is sent into the body from the instrument channel through the operation of the operation handle, a tissue specimen or a surgical excision is placed into the specimen bag, and the bag is locked through the operation of the operation handle end stay wire and is taken out through the instrument channel.

The specimen taking device with the operation rod has the characteristics of convenient operation, safe use and the like, and the weakness of the specimen taking device is that the manufacturing is complex, the cost is high, and the working diameter of the specimen taking device is limited by the design outer diameter of the operation rod, so that the puncture outfit matched with the specimen taking device has higher requirements, and the inner diameter of the puncture outfit matched with the specimen taking device is required to be larger than the outer diameter of the operation rod of the specimen taking device.

The specimen taking device without the operation rod is simple in design and structure, but weak in use convenience, and not easy to open after entering the body cavity, and the operation needs to bring the bag body into a patient through the puncture outfit sleeve by means of the noninvasive instrument, so that failure in specimen taking caused by damage to the bag body in the operation process of the instrument is avoided. Considering the convenience of operation, some specimen extraction devices without an operation rod in the market are designed with an insertion sleeve, and the insertion of the puncture outfit sleeve is convenient for the bag to enter the body cavity of a patient when the bag is rolled into the insertion sleeve, but still limited by the sleeve and the diameter of the puncture outfit.
