Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, in particular to a pair of cervical and vaginal wall tissue sampling forceps. Background Art

[0002] In the diagnosis of gynecological diseases, tissue sampling of the cervix and vaginal wall is a commonly used clinical examination method. By obtaining tissue samples from the affected area for pathological analysis, it is possible to effectively determine the presence of conditions such as inflammation, precancerous lesions, or early-stage cancer. Currently, a commonly used sampling tool in clinical practice is a cervical and vaginal wall tissue sampling forceps, which works similarly to a biopsy forceps, obtaining samples from the target tissue area through mechanical clamping.

[0003] Traditional sampling forceps typically consist of two symmetrical blades, a connecting mechanism, and an operating handle. After placing the forceps head on the suspected lesion, the physician manually applies pressure to close the jaws, thereby "clamping" the tissue and removing it. While this method is simple and easy to use, it has many limitations in practice, particularly regarding the accuracy and completeness of the sample.

[0004] 1. Inaccurate sampling location: Because the surface of the cervix and vaginal wall tissue may contain erosion, bleeding, or other lesions, traditional sampling forceps rely on manual operation and visual judgment to locate the sampling point. However, during operation, the forceps head may slip or deviate, failing to accurately align with the target area. As a result, the sample taken is not the actual lesion site required for testing, affecting the reliability of the diagnostic results.

[0005] 2. Tissue damage and incomplete sampling: Traditional sampling forceps use a "clamp-style" sampling method, which can easily cause tissue tearing or fragmentation, especially when dealing with hard or brittle lesions. This not only increases patient discomfort and the risk of local trauma, but can also compromise the integrity of the sampled tissue, affecting the accuracy of subsequent pathological analysis. Summary of the Invention

[0006] The purpose of the present invention is to provide a cervical and vaginal wall tissue sampling forceps, which clamps the target tissue through a clamping component and then uses a cutting component to cut and sample, thereby ensuring the accuracy of the sampling position and avoiding tissue damage and incomplete sampling.

[0028] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0029] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections, direct connections, indirect connections via an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0030] Example 1, a cervical and vaginal wall tissue sampling forceps, such as Figures 1 to 3As shown, it includes an insertion rod 1, one end of which is detachably connected to a transparent telescopic sleeve 2. The telescopic sleeve 2 contains a clamping assembly 3 and a cutting assembly 4. The clamping assembly 3 is used to clamp tissue, and the cutting assembly 4 is used to cut the tissue clamped by the clamping assembly 3. The telescopic sleeve 2 contains a visual assembly 5. The other end of the insertion rod 1 is connected to a handle 6, which is provided with a control panel 7. The clamping assembly 3, cutting assembly 4 and visual assembly 5 are all electrically connected to the control panel 7. When in use, the insertion rod 1 is inserted into the vagina to reach the cervix, and then the clamping assembly 3 is used to clamp the tissue, and then the cutting assembly 4 is used to cut. The visual assembly 5 facilitates observation of the operation process, and the control panel 7 is used during use.

[0031] The cutting assembly 4 includes a rotating motor 41, a telescopic motor 42, a rotating shaft 43, and a cutting blade 44. A slot 11 is provided at the end of the insertion rod 1 near the telescopic sleeve 2. The rotating motor 41 is mounted in the slot 11 and slidably connected to the slot 11. The telescopic motor 42 is mounted in the insertion rod 1. The output shaft of the telescopic motor 42 is connected to the rotating motor 41. The rotating shaft 43 is connected to the output shaft of the rotating motor 41. The cutting blade 44 is detachably mounted on the end of the rotating shaft 43 away from the rotating motor 41. The cutting blade 44 is arranged radially along the telescopic sleeve 2. The rotating motor 41 and the telescopic motor 42 are both electrically connected to the control panel 7. The clamping assembly 3 is provided with multiple blades evenly arranged around the rotating shaft 43. The position of the cutting blade 44 is adjusted by the telescopic motor 42, and then the rotating shaft 43 and the cutting blade 44 are driven to rotate by the rotating motor 41 to cut the tissue clamped by the clamping assembly 3. This is simple and convenient.

[0032] The clamping assembly 3 in this embodiment includes a suction tube 31, a connecting tube 32, a collection tube 33, a mounting sleeve 34, a solenoid valve 35, and an air outlet pipe 36. The suction tube 31 is evenly distributed around the rotating shaft 43. The end of the suction tube 31 near the insertion rod 1 extends outward to the outside of the telescopic sleeve 2 and is connected to the connecting tube 32. The end of the connecting tube 32 away from the suction tube 31 is connected to the collection tube 33. The mounting sleeve 34 is removably mounted on the end of the insertion rod 1 near the handle 6. Multiple solenoid valves 35 are provided and evenly mounted within the mounting sleeve 34. The collection tubes 33 are each removably connected to the solenoid valve 35. The other end of the collection tube 33 is connected to the connecting tube 32. The other end of the solenoid valve 35 is connected to the air outlet pipe 36. The solenoid valve 35 is electrically connected to the control panel 7. A filter 37 is provided within the suction tube 31. During use, the outlet tube 36 needs to be connected to the hospital's negative pressure system or negative pressure machine. Then, the suction tube 31 is used to align with the tissue and suck the tissue into the suction tube 31. The collection cylinder 33 is used to collect liquid, and the filter 37 prevents the cut tissue from entering the blade collection cylinder 33. After sampling, the sample can be removed with tweezers. Multiple clamping assemblies 3 can be used for multiple sampling to ensure the accuracy of the sample.
