A laparoscopic sample fixation and removal device

Abstract

The invention discloses a specimen fixing and taking-out device under a celioscope. The specimen fixing and taking-out device comprises a pipe sleeve, wherein a control pipe is arranged in the pipe sleeve; an electric telescopic rod is arranged in the control pipe; a fetching unit is movably connected to the electric telescopic rod; an opening unit is arranged at the lower part of the pipe sleeve;the opening unit comprises a plurality of springs I which are arranged on the inner wall of the pipe sleeve; an opening claw is correspondingly mounted on each spring I; the upper part of the controlpipe is fixed in the pipe sleeve through a one-way bearing; and a protrusion is arranged at the periphery of the lower part of the control pipe; the control pipe rotates, so that the protrusion is incontact with the opening claws, the springs I are compressed, and the opening claws are opened. Through the adoption of the specimen fixing and taking-out device disclosed by the invention, solid tissue can be separated from liquid or fluid tissue, and when a fetching bag enters a minimally invasive hole and the fetching bag is taken out from the minimally invasive hole, and the minimally invasive hole can be minimally expanded, so that the specimen can be smoothly taken out from the fetching bag.

Description

technical field [0001] The invention belongs to the field of surgical medical instruments, in particular to a laparoscopic specimen fixing and taking-out device. Background technique [0002] At present, with the continuous development of science and technology, medicine has made rapid progress, and the surgical method has developed from traditional open surgery to endoscopic surgery; laparoscopic surgery has the characteristics of small trauma, fine operation, less bleeding, and quick recovery. The operation can be completed with an incision of only one hour, but the removal of the specimen after the operation requires a corresponding incision according to the size of the specimen. Although the traditional specimen removal bag has a certain tension, its strength is obviously insufficient.

Problems solved by technology

[0002] At present, with the continuous development of science and technology, medicine has made rapid progress, and the surgical method has developed from traditional open surgery to endoscopic surgery; laparoscopic surgery has the characteristics of small trauma, fine surgery, less bleeding, and quick recovery. The operation can be completed with an incision of only one hour, but the removal of the specimen after the operation requires a corresponding incision according to the size of the specimen. Although the traditional specimen removal bag has a certain tension, its strength is obviously insufficient. Under the continuous extrusion of the incision, the specimen gradually moved to the bottom of the specimen bag, which made the diameter of the specimen continue to expand, and a large incision had to be made to take out the specimen, which increased the surgical trauma and prolonged the operation time. It is easy to tear the specimen bag, causing the specimen to be squeezed and broken, which will affect the pathology

[0003] In order to solve the above-mentioned technical problems, the application publication number is CN108209981A discloses a laparoscopic specimen taking device, comprising a main rod. The main rod is provided with a first through hole and a second through hole, and one end of the main rod is fixedly provided with a second through hole. A blade, a second blade is hinged on the first blade, a first swivel is arranged at the hinge point of the second blade, a first handle is arranged on the end of the main rod away from the first blade, and a second handle is hinged on the first handle. Two handles, a second swivel ring is set at the hinge point of the second handle, a stretching rod is set in the second through hole, an elastic ring is set at one end of the stretching rod close to the first blade, and a storage ring is set on the elastic ring A grip handle is provided at the end of the stretching rod close to the first handle; however, the storage bag of this patent mixes solid tissue and liquid or liquid tissue, and the solid tissue needs to be cut into pieces during the removal process, and there is a possibility of cutting and storing Leakage of diseased tissue or fluid into the abdominal cavity or contamination of the incision and surgical area, or even splashing on the face of the surgeon, causing serious adverse effects

[0004] In order to solve the above technical problems, the Chinese patent with the authorized notification number CN104274215B discloses a solid-liquid separation type laparoscopic retrieval bag, which includes an outer bag and an inner bag sleeved in the outer bag. The mouth of the bag is directed in the same direction, the bottom of the inner bag is separated from the bottom of the outer bag, and a suction pipe is sandwiched between the outer bag and the inner bag, one end of the suction pipe extends into the outer bag, and the other end extends into the outer bag. Out of the mouth of the outer bag, the inner bag is a porous or mesh structure that allows the solution to pass through. The invention adopts a double-layer design, and only the mouth of the inner bag and the outer bag can be glued together. After the object bag and during the subsequent removal process, the liquid and liquid samples seep from the inner bag into the outer bag, and the solid samples are cut into pieces and taken out without contact with the outer bag, which avoids the risk of the bag being broken, but the patent Pulling is required during the extraction process, and the volume of the extraction bag is reduced after using the suction device to continuously absorb the liquid. The extraction process is complicated and the specimen cannot be taken out immediately
