Description

Technical Field

[0001] This utility model relates to the technical field of medical devices and related fields, and in particular to a forceps for retrieving objects through a laparoscopic abdominal incision. Background Technology

[0002] Currently, when retrieving specimens after ovarian cyst or adnexal removal, the specimen is first placed into a retrieval bag under laparoscopy. Then, the laparoscopic instruments are removed, and the excised tissue is retrieved through an abdominal incision. However, in practice, due to the narrow space of the abdominal incision, the thickness of the abdominal wall, and the large size of the excised cyst or adnexa, traditional clamping techniques often fail to easily retrieve the specimen. In some cases, the clamps may become lodged in the abdominal wall opening. Repeated pulling can easily cause the specimen to fragment, or even puncture the retrieval bag, posing a risk of lesion dissemination.

[0003] Furthermore, the commonly used uterine forceps, commonly known as ovum forceps, are round-headed forceps frequently used to grasp tissue. Due to their perforation-preventing round-head design, they are often used clinically for the retrieval of tissues that require protection of internal organs. The uterine forceps consist of two metal rods, two finger ring handles at the tail end, and a central fixing screw. The head end has a slightly curved shape formed by the interlocking structure of the two round heads. After the locking clips are engaged, the interlocking heads form a cross-shaped interlocking section with an anti-slip thread design. When grasping tissue from the retrieval bag, the tissue can stretch the forceps heads, causing the ovum forceps to become embedded in the abdominal wall opening within the abdominal cavity, making them difficult to remove. Although the ovum forceps have an anti-slip thread design, in actual operation, the contact area with the tissue is relatively small, making it easy for the tissue to slip, fragment, or even rupture the retrieval bag, increasing the risk of tissue dissemination into the abdominal cavity. This significantly increases the difficulty of retrieval via laparoscopic abdominal incision, prolongs the operation time, and causes considerable inconvenience to the surgeon. Utility Model Content

[0004] In view of this, and to solve the above problems, the purpose of this utility model is to provide a forceps for retrieving objects via a laparoscopic abdominal incision, comprising:

[0005] First handle, second handle, first clamp body, second clamp body;

[0024] like Figure 1 The image shows a preferred embodiment of a laparoscopic abdominal incision retrieval forceps, comprising: a first handle 1, a second handle 2, a first forceps body 3, and a second forceps body 4.

[0025] The middle part of the first handle 1 and the middle part of the second handle 2 are rotatably mounted via a pivot 5; the front end of the first handle 1 is equipped with a first clamp body 3, the transverse cross section of the first clamp body 3 is arc-shaped, the first clamp body 3 is provided with a first groove 6, and the interior of the first groove 6 is provided with a first rack 8; the front end of the second handle 2 is equipped with a second clamp body 4, the transverse cross section of the second clamp body 4 is arc-shaped, the second clamp body 4 is provided with a second groove 7, and the edge of the second groove 7 is provided with a second rack 9, the second clamp body 4 is located inside the first clamp body 3, and the second rack 9 meshes with the first rack 8.

[0026] In practical use, the first clamp 3 and the second clamp 4 each employ a larger clamp and a smaller clamp, respectively. Through the meshing structure of the first clamp 3 and the second clamp 4, tissue can be grasped. Furthermore, because the first clamp 3 and the second clamp 4 are meshed through the first rack 8 and the second rack 9, the first clamp 3 and the second clamp 4 can completely cover the tissue. During the tissue retrieval surgery, the first clamp 3 and the second clamp 4 can more easily fix the tissue in the retrieval bag, prevent slippage, reduce the risk of damage to surrounding organs, and reduce the risk of lesion implantation caused by tissue fragmentation. In addition, the first clamp 3 and the second clamp 4 are connected through the first handle 1 and the second handle 2. The instrument design is simple and convenient for surgical operation, ensuring safer and more effective removal of tissue from the retrieval bag through the narrow abdominal wall incision of the laparoscopy, thereby reducing surgical operation risks, making the surgery more convenient and easier, and reducing surgical complications.

[0027] Based on the above, this utility model also has the following embodiments:

[0028] Furthermore, a laparoscopic abdominal incision retrieval forceps, wherein the first handle 1 includes a first rod body 10 and a second rod body 11 connected in sequence, and the first rod body 10 and the second rod body 11 are provided at a certain angle.

[0029] Furthermore, a laparoscopic abdominal incision retrieval forceps includes a second handle 2 comprising a third handle 13 and a fourth handle 14 connected sequentially, with a certain angle between the third handle 13 and the fourth handle 14. The junction of the first handle 10 and the second handle 11 with the junction of the third handle 13 and the fourth handle 14 is connected by a pivot 5. Specifically, the user holds the first handle 10 and the third handle 13, moving them closer or further apart, thereby causing the second handle 11 and the fourth handle 14 to move closer or further apart, and ultimately causing the first forceps 3 and the second forceps 4 to move closer or further apart, thus gripping or releasing the tissue.

[0030] Furthermore, a laparoscopic abdominal incision retrieval forceps includes a second rod 11 with a mounting groove 12 communicating with a first groove 6, and a fourth rod 14 capable of being installed in the mounting groove 12. Specifically, when the first rack 8 and the second rack 9 are engaged, the fourth rod 14 is embedded in the mounting groove 12, and the double-layer fixation prevents the first forceps 3 and the second forceps 4 from disengaging, thus preventing tissue from falling out.

[0031] Furthermore, a laparoscopic abdominal incision retrieval forceps includes a first finger ring 15 at the end of the first rod 10 away from the pivot 5, and a second finger ring 16 at the end of the third rod 13 away from the pivot 5. Specifically, the user's fingers can be inserted into the first finger ring 15 and the second finger ring 16 to operate the first handle 1 and the second handle 2, making it more convenient to use.

[0032] Furthermore, a laparoscopic abdominal incision retrieval forceps is provided, wherein both the first forceps body 3 and the second forceps body 4 are approximately elliptical in shape, with the second forceps body 4 extending completely into the interior of the first groove 6. Specifically, the second forceps body 4 is completely embedded in the first forceps body 3, which avoids the first forceps body 3 and the second forceps body 4 from intersecting, thus preventing them from getting stuck and becoming unusable.

[0033] Furthermore, a laparoscopic abdominal incision retrieval forceps is provided, wherein a receiving space is formed between the first forceps body 3 and the second forceps body 4. Specifically, since both the first forceps body 3 and the second forceps body 4 are arc-shaped, after the first forceps body 3 and the second forceps body 4 are engaged by the first rack 8 and the second rack 9, a receiving space for holding tissue can be formed between them. The receiving space is closed, thereby preventing tissue from falling out or breaking.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
