Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing technology, specifically to a laparoscopic specimen retrieval device. Background Technology

[0002] Laparoscopic surgery is now widely used, and with the improvement of living standards, patients are more willing to choose it. The most important advantages of laparoscopic surgery are smaller incisions, less bleeding, and faster postoperative recovery. However, most tumors removed during laparoscopic surgery are larger than the incision size, making the retrieval of the removed tumor specimen one of the surgical challenges. In some laparoscopic surgeries, the specimen retrieval time far exceeds the specimen removal time, increasing the operation time, as well as the patient's anesthetic dosage and the risk of infection. Because the laparoscopic incision is generally only 1-2 cm, some hospitals choose to extend the incision to retrieve the specimen, thus negating the minimally invasive nature of laparoscopy. Based on current clinical difficulties, uterine tumor fragmentation drills and tumor retrieval bags have been invented and are widely used in laparoscopic uterine tumor resection. However, for tumors such as ovarian cysts, which are not as hard as large tumors, there are currently no suitable specimen retrieval tools. In clinical surgery, when removing tumors such as ovarian cysts, the surgeon and assistant need to work together to cut the tumor into pieces with a scalpel or tissue scissors through an incision of 1-2 cm in diameter, and then remove it little by little with ovum forceps or curved forceps. This procedure increases the operation time and raises the occupational exposure rate of the surgeon. Utility Model Content

[0003] The purpose of this invention is to provide a laparoscopic specimen retrieval device to solve the above-mentioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A laparoscopic specimen retrieval device includes a handheld part with an outer tube fixedly mounted thereon, and an inner tube fixedly connected to the output end of a rotary motor fixedly mounted inside the outer tube.

[0006] The outer tube has a cutting edge notch distributed near the end on its side wall, and the inner tube has an inner cutting edge notch corresponding to the position of the cutting edge notch.

[0007] Preferably, a first flange connector is fixedly provided on the hand-held part, and the first flange connector communicates with the interior of the outer tube body;

[0008] A second flange connector is fixedly installed on the handpiece, and the second flange connector communicates with the interior of the inner tube.

[0009] Preferably, the end of the outer tube is a spherical cap, and the end of the inner tube is an open opening, the open opening being located at the junction of the outer tube and the spherical cap.

[0010] Preferably, the inner wall of the inner notch is provided with an elastic arc-shaped cutting edge, and the end of the elastic arc-shaped cutting edge is flush with the side of the outer tube when the inner notch corresponds to the cutting edge notch.

[0011] Preferably, the outer wall of the handheld part is provided with a silicone outer sheath.

[0012] In the above technical solution, the laparoscopic specimen retrieval device provided by this utility model has the following beneficial effects: it uses suction to aspirate the tumor into the inner tube, and then rotates the inner tube to misalign the cutting notch and the inner cutting notch, thereby completing the cutting.

[0013] An air pump is used to inflate the outer tube. The airflow enters through the gap between the outer and inner tubes and then flows in through the opening. At the same time, suction is used to remove the tumor from the inner tube. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, a laparoscopic specimen retrieval device includes a handheld part 1 (with a silicone outer sheath on the outer wall), an outer tube 2 fixedly mounted on the handheld part 1, and an inner tube 3 rotatably mounted inside the outer tube 2 and fixedly connected to the output end of a rotary motor fixedly mounted inside the handheld part 1.

[0023] The outer tube 2 has a cutting edge notch 21 distributed near the end on its side wall, and the inner tube 3 has an inner cutting edge notch 31 corresponding to the position of the cutting edge notch 21.

[0024] When using it, first connect the suction pump to the second flange connector 5, and then connect the air pump to the first flange connector 4, because the first flange connector 4 is connected to the inside of the outer pipe 2, while the second flange connector 5 is connected to the inside of the inner pipe 3.

[0025] Furthermore, in combination Figure 3 As can be seen, in the embodiment, the end of the outer tube 2 is a spherical cap 22, and the end of the inner tube 3 is an open end 32, which is located at the junction of the outer tube 2 and the spherical cap 22.

[0026] During the procedure, the tumor is aspirated into the inner tube 3 using suction, and then the inner tube 3 is rotated to misalign the cutting notch 21 and the inner cutting notch 31, thereby completing the cutting.

[0027] An air pump is used to inflate the outer tube 2. The airflow enters through the gap between the outer tube 2 and the inner tube 3, and then flows in through the opening 32. At the same time, suction is used to remove the tumor from the inner tube 3.

[0028] Furthermore, combining Figure 4 As shown, in this embodiment, the inner wall of the inner notch 31 is provided with an elastic arc-shaped blade 6. Corresponding to the blade notch 21, the end of the elastic arc-shaped blade 6 is flush with the side of the outer tube 2. Therefore, when the inner tube 3 is rotated by the rotary motor, the elastic arc-shaped blade 6 moves towards the inside of the inner tube 3 as it becomes tangential to the blade notch 21, thereby pulling the tumor towards the inside of the inner tube 3. Once the inner notch 31 and the blade notch 21 are completely misaligned, the tumor is completely removed.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
