Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a device for extracting endoscopic specimens. Background Technology

[0002] The laparoscopic specimen retrieval device allows for convenient removal of specimens at the end of surgery. At the same time, placing the specimen in a retrieval bag can effectively prevent the specimen from directly contacting the incision, which could lead to postoperative wound infection or iatrogenic implantation metastasis caused by the shedding of malignant tumor cells. It is an indispensable instrument for laparoscopic or thoracoscopic surgery.

[0003] Existing retrieval devices use steel wires to connect the retrieval bag. The bag is unfolded by unfolding the steel wires, which makes it easier for medical staff to use. However, the steel wires are quite hard and can easily damage abdominal or thoracic organs during use. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and to propose a laparoscopic specimen retrieval device. The technical solution adopted by this invention is as follows:

[0005] A laparoscopic specimen retrieval device includes a retrieval assembly comprising a bendable head, a plastic wire, a connecting slide buckle, and a retrieval bag. The plastic wire is connected to the right side of the bendable head, the connecting slide buckle is installed on the plastic wire, and the retrieval bag is fitted over the plastic wire. The length of the plastic wire is between 40 and 50 centimeters, and the length of the bendable head is 2 centimeters.

[0006] As an improvement, the left side of the extraction component is connected to a propulsion component, and the outside of the propulsion component is connected to an outer casing component.

[0007] As an improvement, the outer casing assembly includes an outer casing rod and finger openings, with finger openings connected to the upper and lower sides of the outer casing rod.

[0008] As an improvement, the propulsion assembly includes a propulsion rod and a propulsion head, with the propulsion head connected to the left side of the propulsion rod.

[0009] The beneficial effects of this utility model are as follows:

[0010] This utility model discloses a laparoscopic specimen retrieval device that replaces steel wire with plastic thread, which is more flexible and less likely to damage abdominal or thoracic organs. At the same time, the sliding buckle design facilitates the sliding of the plastic thread head, thereby making it easier to unfold the retrieval bag for use. Attached Figure Description

[0015] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0016] like Figure 1 and Figure 2 As shown, component 3 is removed. Component 3 includes a bendable head 301, a plastic wire 302, a connecting slip buckle 303, and a retrieval bag 304. The plastic wire 302 is connected to the right side of the bendable head 301. The connecting slip buckle 303 is installed on the plastic wire 302, and the retrieval bag 304 is wrapped around the plastic wire 302. The length of the plastic wire 302 is between 40 and 50 centimeters, and the length of the bendable head 301 is 2 centimeters. Replacing the steel wire with the plastic wire 302 provides better flexibility and is less likely to damage abdominal or thoracic organs. At the same time, the design of the connecting slip buckle 303 facilitates the sliding of the head of the plastic wire 302, thereby making it easier to unfold and use the retrieval bag 304.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, the left side of the removed component 3 is connected to the propulsion component 2, and the outside of the propulsion component 2 is connected to the outer casing component 1.

[0018] like Figure 1 and Figure 2 As shown, the outer sleeve assembly 1 includes an outer sleeve rod 101 and a finger opening 102, and the upper and lower sides of the outer sleeve rod 101 are connected to the finger openings 102.

[0019] like Figure 1 and Figure 3 As shown, the propulsion assembly 2 includes a propulsion rod 201 and a propulsion head 202, and the propulsion head 202 is connected to the left side of the propulsion rod 201. In the working state, the length of the propulsion rod 201 extending from the outer sleeve rod 101 is five centimeters.

[0020] In existing products, once the retrieval bag 304 is inserted into the abdominal or thoracic cavity to hold the specimen, it must be removed before the surgery can continue. However, the improved product has a plastic thread 302 connecting the retrieval bag 304 to the outside. For specimens, especially malignant tumor specimens, that do not need to be removed immediately, they can be placed in the retrieval bag 304 and placed in the abdominal or thoracic cavity, allowing the surgery to continue. The specimen can be removed after the surgery. This effectively prevents the specimen from being exposed inside the body and causing iatrogenic tumor cell shedding and spread due to surgical procedures.

[0021] During use, the device is first removed from the packaging bag. Then, the finger is held in place by the finger opening 102. At this time, the medical staff inserts the front end of the outer rod 101 into the body, reaching the area to be used. The medical staff then pushes the push head 202, causing the push rod 201 to push the extraction component 3 out of the outer rod 101. After the extraction component 3 is pushed out, the plastic thread 302, which has its own elasticity, will unfold. During unfolding, one end of the plastic thread 302 will slide on the plastic thread 302 through the connecting slip buckle 303, thereby unfolding the plastic thread 302 into a circle-like shape, thus opening the retrieval bag 304. The retrieval bag 304 is then placed at the lower end of the tumor, and surgery can be performed to remove the tumor. The removed tumor falls into the retrieval bag 304 for collection. The bendable head 301 can be bent to prevent the thread of the retrieval bag from falling into the abdominal or thoracic cavity.

[0022] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
