Surgical sample taking device and application method and application of device

Abstract

The invention provides a surgical sample taking device and an application method and application of the device. The surgical sample taking device comprises an external tube, a fixing handle, a pull rod, a movable handle, a taking bag and a pull rope. An X-shaped elastic part is formed at the far end of the pull rod, a first elastic arm and a second elastic arm are inserted in a connection rollingedge of the taking bag, and the taking bag extends to form a tongue-shaped structure at an opening and is inserted in the root of the X-shaped elastic part. The method comprises the following steps that the surgical sample taking device enters the body through a puncture channel, the movable handle is pushed, and accordingly the taking bag extends out of the outer tube and is opened; a surgical sample is extracted; the movable handle is pulled until the movable handle is pulled out of the outer tube; the pull rope is pulled, so that the taking bag is closed; the outer tube and the taking bag are taken out of the puncture channel at the same time. The surgical sample taking device is simple in structure and easy to assemble, the space is saved, the manufacturing and transportation cost is lowered, the application method is easy and convenient to use, misoperation can be avoided, and the use safety is improved.

Description

technical field [0001] The present application relates to the field of medical devices, and in particular, relates to a device for obtaining surgical specimens and a method and application thereof. Background technique [0002] Compared with traditional surgical methods, minimally invasive surgery has small wounds, less pain, and faster recovery for patients, and has been vigorously promoted and popularized clinically. In minimally invasive surgery, it is often necessary to remove tissue samples or surgical resections obtained during surgery. For this reason, various retrieval bags for recovering surgical specimens have been developed, such as U.S. Patent No. 5,971,995, Chinese Patent Publication No. CN204133504U, Chinese Patent No. The disclosed operation specimen bag of publication number CN2676833Y. The structure of these surgical specimen bags usually includes two parts: a bag body and an operating rod: the bag body is usually made of long tapered water-proof textile or...

AI Technical Summary

Problems solved by technology

However, the existing surgical specimen retrieval bags have problems such as complex structure, inconvenient use, and easy misoperation.

For example, U.S. Patent No. 9,414,817 discloses a surgical tissue extraction device, which uses a distal fork-shaped fixing device to fix the bag, and releases the bag body in combination with a spring, so as to achieve the bag body into the operating rod of the extraction bag And the purpose of releasing into the patient's body, although the rebound mechanism is simple to operate, but there are many designed objects and molds, so the material cost and assembly cost are high

In addition, more products on the market use redundant bag body extensions to connect to the handle end of the operating rod for fixation (such as GeniStrong products from Genicon in the United States, etc.), and their manufacturing process and operation methods are more complicated.
