Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a simple transvaginal surgical specimen removal device. Background Technology

[0002] Laparoscopic minimally invasive surgery, due to its advantages of minimal trauma, less bleeding, and faster postoperative recovery, has been widely used in various disciplines, gradually replacing traditional open surgery. With technological advancements, the indications for laparoscopic minimally invasive surgery in gynecology have expanded from benign diseases such as uterine fibroids and adenomyosis to malignant diseases such as early-stage endometrial cancer and cervical cancer. The removal of surgical specimens must adhere to the principle of tumor-free extraction. For gynecological surgery, the vagina, a natural passage, is the optimal method, minimizing surgical trauma and shortening postoperative recovery time. Currently, specimens are usually placed in disposable specimen bags and delivered intact through the vagina. However, when the specimen is too large or the vagina is too narrow, it is impossible to remove the specimen vaginally. In such cases, the specimen usually needs to be cut inside the vagina to reduce its size. Without proper protection, this increases the risk of tumor dissemination and metastasis, and this process requires the assistance of multiple assistants. Existing vaginal retractors have limited dilating effect on the vagina, especially for patients with vaginal stenosis or obesity. They cannot fully expose the field of vision, which can easily lead to damage to the vagina and adjacent tissues. When the uterus is too large, the surgeon needs to clamp and pull the uterus backward while cutting it, which can easily lead to surgeon fatigue. In addition, the pressure of the specimen on the vaginal stump can also easily lead to tearing and bleeding at the vaginal stump. Furthermore, the prolonged operation time and prolonged vaginal manipulation also increase the risk of anesthesia and retrograde infection through the vagina. Utility Model Content

[0003] In view of this, the present invention aims to propose a simple transvaginal surgical specimen retrieval device to solve the problems of existing gynecological surgeries where the retrieval of surgical specimens must follow the principle of tumor-free operation to prevent increased risk of tumor dissemination and metastasis, and the inability to fully expose the field of vision, which can easily lead to damage to the vagina and adjacent tissues and the risk of retrograde infection through the vagina.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a simple transvaginal surgical specimen removal device, comprising a specimen protection bag, a protective ring, and a buckle. The specimen protection bag is rectangular, with one end being an open end. The protective ring is disposed on the outside of the open end of the specimen protection bag. The open end of the specimen protection bag is folded over from the inside of the protective ring and fitted onto the outside of the protective ring. The buckle is engaged with the outside of the folded portion of the specimen protection bag and cooperates with the protective ring.

[0005] Furthermore, the specimen protection bag has an elastic coil at its open end.

[0006] Furthermore, the number of the buckles is three, and the three buckles are spaced apart circumferentially.

[0007] Furthermore, the circumference of the protective ring is smaller than the circumference of the opening end of the specimen protection bag.

[0008] Furthermore, the specimen protection bag is made of a transparent plastic film.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0021] See Figure 1-4 This embodiment describes a simple transvaginal surgical specimen retrieval device, comprising a specimen protection bag 1, a protective ring 2, and a buckle 3. The specimen protection bag 1 is rectangular, with one end being an open end. The protective ring 2 is positioned outside the open end of the specimen protection bag 1. The open end of the specimen protection bag 1 is folded over from the inside of the protective ring 2 and fitted onto the outside of the protective ring 2. The buckle 3 is positioned outside the folded portion of the specimen protection bag 1 and engages with the protective ring 2. The buckle 3 secures the folded portion of the specimen protection bag 1 to the protective ring 2. In this embodiment, the separate design of the specimen protection bag 1, protective ring 2, and buckle 3 allows the specimen protection bag 1 to be inserted into the abdominal cavity via laparoscopic insertion, avoiding retrograde infection caused by vaginal insertion.

[0022] In this embodiment, the open end of the specimen protection bag 1 is folded over by the protective ring 2 and the buckle 3, which is more labor-saving than the traditional vaginal retractor and can fully expose the surgical field. The uterus is cut inside the specimen protection bag, reducing the possibility of peritoneal dissemination during the uterine cutting process.

[0023] In this embodiment, the specimen protection bag 1 is provided with an elastic coil 4 at its open end. The elastic coil 4 has a certain elasticity. By squeezing the elastic coil 4, the open end of the protection bag 1 can be tightened. After being relaxed, the elastic coil 4 automatically opens and restores its circular shape.

[0024] In this embodiment, there are three buckles 3, which are spaced apart circumferentially. The number of buckles 3 can be adjusted according to the actual fixing needs.

[0025] In this embodiment, the circumference of the protective ring 2 is smaller than the circumference of the opening end of the specimen protection bag 1. This design of the protective ring 2 serves to tighten the opening of the specimen protection bag 1 when it is folded.

[0026] In this embodiment, the specimen protection bag 1 is made of transparent plastic film, which has the advantages of good flexibility, high tensile strength and low cost.

[0027] In use, the specimen protection bag 1 is inserted into the body through the laparoscopic trocar. The elastic coil 4 on the specimen protection bag 1 deforms when it is inserted into the abdominal cavity through the laparoscopic trocar. After the specimen protection bag 1 is in the abdominal cavity, the elastic coil 4 returns to its circular shape due to its elasticity, thereby opening the opening end of the specimen protection bag 1. The surgical specimen is placed into the specimen protection bag 1, the elastic coil 4 is tightened, the end of the elastic coil 4 is inserted into the vagina, and the opening end of the specimen protection bag 1 is pulled out from the vagina. The elastic coil 4 is then opened, and the protective ring 2 is placed into the folded part of the opening end and fixed with the buckle 3. Then the protective ring 2 is gradually folded until the surgical field is fully exposed. At this time, the surgical specimen can be cut inside the specimen protection bag 1. Then the steps of folding the protective ring 2, fully exposing the surgical field, and cutting the surgical specimen are repeated until the specimen is completely removed from the vagina.

[0028] The simplified transvaginal surgical specimen retrieval device described in this embodiment has a simple structure, is easy to operate, and can be operated by a single person without the need for an assistant.
