[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, the meaning of "multiple" is two or more, such as two, three, etc., unless otherwise clearly defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] like Figure 1 and Figure 2 As shown, the utility model provides a disposable bladder foreign body sampling forceps, comprising: a handle 1, a connecting tube 2, a connecting rope 3 and a sampling forceps head 4, a sliding member 5 is provided on the handle 1, the sliding member 5 slides along the length direction of the handle 1, a sliding groove 6 is provided in the handle 1, the sliding member 5 has a through groove 7, a sliding block 8 is provided at a position corresponding to the through groove 7 and the sliding groove 6, the sliding block 8 is placed in the sliding groove 6, the outer periphery of the sliding member 5 is sleeved with a rotating member 9, the sliding member 5 and the rotating member 9 are rotatably connected, and the rotating member 9 is provided with a first A limit member 10 and a second limit member 11 are provided on the handle 1. The first limit member 10 and the second limit member 11 are interlocked to fix the sliding member 5 on the handle 1. There are two sampling clamps 4. The front ends of the two sampling clamps 4 are engaged with each other for biting and cutting samples. One end of the connecting tube 2 is connected to the handle 1, and the other end of the connecting tube 2 is connected to the middle section of the two sampling clamps 4 through a connecting rod 17. One end of the connecting rope 3 is connected to the sliding block 8, and the other end of the connecting rope 3 is connected to the end of the sampling clamp 4.

[0034] Preferably, the connecting tube 2 is a spring tube, and the outer wall of the spring tube is wrapped with a plastic sleeve.

[0035] As shown Figure 3 in the figure, specifically, pulling the rotating member 9 drives the sliding member 5, and then the sliding block 8 drives the connecting rope 3. The connecting rope 3 is tightened, driving the end of the sampling forceps head 4, and the sampling forceps head 4 closes. The first limiting member 10 on the rotating member 9 is clamped with the second limiting member 11 on the handle 1, fixing the sliding member 5 on the handle 1, so that the top of the sampling forceps head 4 is closed and locked. Rotating the rotating member 9 causes the first limiting member 10 on the rotating member 9 to disengage from the clamping with the second limiting member 11, allowing the sliding member 5 to slide on the handle, releasing the closing and locking of the sampling forceps head 4. Preferably, the sliding member 5 and the rotating member 9 are connected by a bushing 18, making the rotation of the rotating member 9 on the sliding member 5 smoother.

[0036] Furthermore, a collar 12 is provided on the handle 1, and a plurality of second limiting members 11 are circumferentially arranged on the outer peripheral wall of the collar 12. Through the arrangement of multiple second limiting members 11, when pulling the rotating member 9, there is no need to pre-rotate the rotating member 9 to a specific angle, that is, the angle at which the rotating member 9 is located when the first limiting member 10 and the second limiting member 11 are opposite. This improves work efficiency. It should be noted that there is a gap between any two of the plurality of second limiting members 11, and the gap left is greater than the width of the first limiting member 10, ensuring that when rotating the rotating member 9, the sampling forceps head 4 can be unlocked so that the top of the sampling forceps head 4 can open.

[0037] Among them, a support rod 20 is provided on the side of the rotating member 9 close to the collar 12, and a first limiting member 10 is fixedly provided on the support rod 20. The length of the support rod 20 and the setting position of the collar 12 are arranged relatively. So that the rotating member 9 can be fixed on the handle 1.

[0038] Furthermore, a circular ring handle 13 is provided at one end of the handle 1 away from the connecting pipe 2, and an anti-slip rubber pad 14 is provided on the inner side wall of the circular ring handle 13. When holding the handle 1, pass the thumb through the circular ring handle 13, and then clamp the rotating member 9 with the index finger and middle finger. The anti-slip rubber pad 14 increases the friction between the thumb and the circular ring handle 13, making it more firm to hold the handle 1. Among them, the side cross-section of the rotating member 9 is a C-shaped structure with a chamfer. The C-shaped structure is for the index finger and middle finger to be inserted. Preferably, an anti-slip rubber sleeve 19 is provided on the outer peripheral wall of the rotating member 9 close to the handle 1. The anti-slip rubber sleeve 19 increases the friction between the index finger and middle finger and the rotating member 9, making it more convenient to rotate the rotating member 9.

[0039] As shown Figure 4As shown, the disposable bladder foreign body sampling forceps further includes a fixing frame 15, which is arranged at the end of the connecting tube 2 away from the handle 1. The fixing frame 15 includes two fixing plates 16, and a connecting rod 17 is connected between the two fixing plates 16. The connecting rod 17 extends through the middle section of the two sampling forceps heads 4. The two sampling forceps heads 4 are driven to open and close by pulling the connecting rope 3.

[0040] In one embodiment, a spring is provided between the first sampling clamp 401 and the second sampling clamp 402 so that in the initial state, the top of the first sampling clamp 401 and the top of the second sampling clamp 402 are open. By providing the spring, the initial state of the sampling clamp 4 is an open state.

[0041] Foreign bodies in the bladder and urethra can directly cause mechanical irritation and damage to the bladder and urethra, leading to infections of the urethra and surrounding tissues, urinary dysfunction, hematuria, urinary extravasation, stones, bladder fistulas, and urethral fistulas. Because men have longer urethras with two natural bends, foreign bodies are more likely to remain in the bladder and not enter. Women have short, straight urethras, making it easier for foreign bodies to enter the bladder through the urethra. If a foreign body is located in the bladder neck or urethra, and a stone forms around the foreign body, it can cause dysuria or even urinary retention. Therefore, if the foreign body is small and cord-like, it can be removed through the urethra using a sampling forceps under cystoendoscopy.

[0042] In medical settings, disposable sampling forceps are required to avoid cross-contamination and the spread of pathogens. Even disinfection cannot guarantee the complete removal of bacteria or viruses from their surface, so using disposable forceps can maximize sample purity. Disposable forceps also eliminate the need for disinfection or cleaning, reducing steps and time in the workflow. Using disposable forceps can improve work efficiency, especially in situations where frequent sampling is required. It also reduces the risk of cross-contamination between samples that could affect sampling results, thereby minimizing the risk of cross-contamination. Furthermore, while disposable forceps may cost more than reusable tools for a single use, considering the cost and time associated with disinfection and cleaning, they are more economical for long-term use.

[0043] Example

[0044] When the doctor performs a pathological examination on the lesion in the bladder, the doctor holds the sampling forceps, passes his thumb through the ring handle 13, and uses his index and middle fingers to hold the rotating member 9 to insert the sampling forceps head 4 into the corresponding channel of the cystoscope. When the doctor needs to take a sample from the lesion, the doctor pulls the rotating member 9, thereby driving the sliding member 5, and then the sliding block 8 drives the connecting rope 3. The connecting rope 3 is tightened, driving the sampling forceps head 4, and the spring between the two sampling forceps heads 4 is compressed, the sampling forceps heads 4 are closed, and the first limiter 10 on the rotating member engages the second limiter 11 on the handle to fix the sliding member 5 on the handle 1. Finally, the sampling forceps is removed from the corresponding channel of the cystoscope. The doctor holds and rotates the rotating member 9 with his index and middle fingers to rotate the rotating member 9 circumferentially. In this way, the first limiter 10 will disengage from the second limiter 11, so that the rotating member 9 is reset, thereby resetting the connecting rope 3 and the spring between the sampling forceps heads 4.
