Abstract
Description
Technical Field
[0001] The utility model relates to the field of surgical operations, in particular to a novel laparoscope retrieval bag with a cutting function. Background Art
[0002] Laparoscopy, as a minimally invasive surgical method, has been maturely applied and is most suitable for the treatment of certain benign diseases and early tumors. For example, it can be used to perform minimally invasive treatments for diseases such as fenestration of liver cysts, resection of colorectal tumors, resection of abdominal and gastric leiomyoma, and splenectomy for hypersplenism caused by various reasons, with significant results.
[0003] In the prior art, tumor removal is usually achieved by inserting a laparoscopic retrieval bag into the trocar, wrapping the foreign body and then pulling it out through the trocar. However, due to the large volume of the resected tissue, it is often impossible to pass through the trocar. To address the above problem, a laparoscopic retrieval bag with a cutting knife is disclosed in Chinese patent 201721903173.X. Although the device can remove the retrieval bag by secondary cutting of the excised tissue, its implementation process is very cumbersome and requires repeated stretching to shred the tissue. In addition, the device is expensive and complicated to operate. It uses high-cost equipment such as memory materials and requires multiple knife bodies to work together, which also increases the difficulty of operating the device. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a new type of laparoscopic retrieval bag with a cutting function which has a simple structure, uses a sharp metal wire as the inner lining of the laparoscopic retrieval bag, can quickly perform secondary cutting on the excised tissue, and is easy to operate.
[0005] The device comprises a bag body, wherein a tumor cutting net is arranged inside the bag body, and the tumor cutting net is composed of a plurality of thin metal wires arranged in a uniform array around the inner surface of the bag;
[0006] A wire loop is arranged at the end of the thin metal wire, and a tightening wire rope is passed through the wire loop.
[0007] The effect achieved in this way is that after the tumor enters the retrieval bag, the bag mouth is first tightened to a small hole. The purpose of implementing this step is to make the outside of the tumor basically fit with the bag body; then the tumor cutting net is partially taken out by pulling the tightening rope. The purpose of implementing this is that when the outside of the tumor is basically fit with the bag body, the fine metal wire wraps the outside of the tumor, and the tumor is cut into multiple small pieces at one time by pulling, thereby achieving the effect of taking out a tumor with a larger outer diameter from the trocar.
[0008] The beneficial effects of the utility model are as follows: the utility model solves the problem of the inconvenience of removing large tumors. Compared with the laparoscopic retrieval bag in the prior art, it especially solves the problems of inconvenient equipment operation, complicated procedures and high costs. It realizes the rapid secondary segmentation of large tumors through a simple structure, and the tumor can be divided into multiple pieces in one wash, which has great market promotion value.

[0014] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0015] Reference Figure 1 , Figure 2 The utility model discloses a new type of laparoscope bag with cutting function, comprising a bag body 5, the inner surface of which is provided with a tumor cutting net 4, wherein the tumor cutting net 4 is composed of a plurality of thin metal wires uniformly arranged in an array around the inner surface of the bag;
[0016] A wire loop 6 is arranged at the end of the thin metal wire, and a tightening wire rope 1 is passed through the wire loop 6 .
[0017] The effect achieved in this way is that after the tumor enters the retrieval bag, the bag mouth is first tightened to a small hole. The purpose of implementing this step is to make the outside of the tumor basically fit with the bag body; then the tumor cutting net 4 is partially taken out by pulling the tightening rope 1. The purpose of implementing this step is that when the outside of the tumor is basically in contact with the bag body, the fine metal wire wraps the outside of the tumor, and the tumor is cut into multiple small pieces at one time by pulling, thereby achieving the effect of taking out a tumor with a larger outer diameter from the trocar.
[0018] Furthermore, the tumor cutting net 4 is arranged on the inner surface of the taking bag body 5 by means of a limiting piece 7;
[0019] The limiting piece 7 is fixedly arranged on the inner surface of the taking bag body 5 by being glued or integrally arranged, and a slit connection section is provided on the limiting piece 7 along the arrangement direction of the thin metal wire.
[0020] The limiting pieces 7 mentioned here are all made of a plastic film material whose material strength is much lower than that of the retrieval bag body 5, so as to facilitate the positioning between the tumor cutting net 4 and the retrieval bag body 5 and the rapid separation during the implementation process.
[0021] Furthermore, the limiting pieces 7 are respectively arranged at the bag opening of the taking bag body 5 and the bottom surface of the taking bag.
[0022] Preferably, the limiting piece 7 arranged on the bottom surface of the taking bag body 5 is a circular patch of a thin plastic film, and the limiting piece 7 is provided with slit connecting sections arranged in a cross shape.
[0023] Furthermore, a handle 3 is provided at the rear of the picking bag body 5, and the handle 3 is a hollow handle 3, and a picking bag operating rod 2 is sleeved in the handle 3;
[0024] That is to say, its configuration is in the form of a common laparoscope retrieval bag in the prior art;
[0025] The bag-taking operating rod 2 is provided with a through slot in the center, and the tightening rope 1 passes through the through slot, with the tail end thereof protruding out of the bag-taking operating rod 2 .
[0026] Preferably, a pull ring is also provided at the tail end of the tightening cord 1, which is used for the convenience of pulling and one-way limiting.
[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
