Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a laser-fixed anti-spray device. Background Technology

[0002] In ureteroscopy, irrigation is crucial. It not only maintains a clear surgical field, facilitating precise manipulation by the surgeon, but also promptly removes tissue debris generated during the procedure, ensuring its smooth execution. Currently, to improve the sealing of the ureteroscopic access channel and reduce the risk of irrigation fluid leakage, anti-spray devices are often added to the outside of the access channel. These devices are connected to the ureteroscope via snap-fit ​​or splicing mechanisms, forming an additional protective barrier to prevent irrigation fluid leakage.

[0003] However, due to the vast differences in the specifications of the instruments used in surgery, ranging from thin guidewires to large-diameter stone forceps, existing anti-spray devices are prone to stretching and deformation after being repeatedly inserted by instruments of different sizes. Over time, this can even lead to cracking of the device, significantly reducing its anti-spray effect and failing to meet the stringent sealing requirements of surgery. Utility Model Content

[0004] The present invention aims to provide a laser-fixed anti-spray device to solve the problem that existing devices are stretched and cracked due to frequent exposure to instruments of different sizes, ultimately leading to leakage of rinsing fluid.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The basic technical solution provided by this utility model is: a laser-fixed anti-spray device, including a sealing cap, the sealing cap having a through hole, an elastic membrane being provided inside the through hole, the elastic membrane being composed of several sealing flaps, a sealing tube being fixedly connected to the sealing cap, a sealing threaded column being slidably connected inside the sealing tube, and a rotary switch being rotatably connected outside the sealing tube, the rotary switch being threadedly connected to the sealing threaded column.

[0007] The principle of the basic technical solution is as follows: When the surgical instrument passes through the through-hole of the sealing cap, the elastic membrane composed of several sealing flaps will adaptively expand according to the shape and size of the instrument, tightly adhering to the instrument surface. After the instrument is withdrawn, it will restore the seal through its own elasticity. At the same time, rotating the rotary switch outside the sealing tube, based on the principle of threaded transmission, causes the sealing thread to slide linearly inside the sealing tube due to the threaded connection between the rotary switch and the sealing thread inside the sealing tube. This sealing thread then closes the through-hole on the sealing cap.

[0008] The beneficial effects of the basic technical solution are: the elastic membrane, composed of sealing flaps, can adaptively adjust to different sizes of surgical instruments. It can tightly wrap around instruments of varying sizes, effectively preventing gas leakage during instrument operation. During the irrigation phase, sealing the through-holes by operating the sealing threaded post effectively prevents irrigation fluid leakage.

[0009] Preferably, the bottoms of several of the sealing flaps are integrally formed, and the tops of two adjacent sealing flaps abut against each other.

[0010] With the above-mentioned design, the bottom is integrally molded, enhancing the stability of the elastic membrane structure and preventing misalignment and separation of the sealing flap during frequent use. The tops abut against each other, improving sealing performance. The membrane closes tightly when surgical instruments do not pass through, opens flexibly when they do, and quickly recovers after withdrawal, effectively preventing leakage of irrigation fluid and gas, and also optimizing adaptive adjustment for instruments of different sizes.

[0011] Preferably, the sealing flap is made of silicone material.

[0012] Through the above design, the soft and elastic silicone material can easily adapt to the size of various surgical instruments, tightly wrapping them and achieving excellent leak-proof and air-proof effects. At the same time, it possesses good chemical stability, is not easily corroded by irrigation fluids or other substances during surgery, and can ensure long-term reliability.

[0013] Preferably, the sealing tube is provided with a limiting ring, and the rotary switch is provided with a locking groove that matches the limiting ring.

[0014] Through the above settings, the combination of the limiting ring and the locking groove effectively prevents the rotary switch from sliding accidentally due to external forces such as vibration and collision during use, eliminating the risk of the rotary switch separating from the sealing tube and ensuring that the entire device maintains a stable and reliable sealing adjustment function throughout the entire operation.

[0015] Preferably, the sealing tube is provided with a plurality of limiting grooves, one side of the sealing threaded post is provided with a limiting protrusion that matches the limiting groove, and the other side of the sealing threaded post is provided with an external thread for threaded connection with the rotary switch.

[0016] With the above settings, the limiting groove and the limiting protrusion cooperate to provide precise positioning and guidance for the movement of the sealing threaded column, ensuring that it moves stably under the drive of the rotary switch and avoiding deviation.

[0017] Preferably, the diameter of the sealing threaded post is larger than the diameter of the through hole.

[0018] The above setup achieves complete sealing of the through-hole. When the sealing threaded post moves to a specific position to seal the through-hole, its diameter is larger than that of the through-hole, allowing it to completely cover the through-hole, thus physically eliminating the possibility of gas leakage from the through-hole to the outside.

[0019] Preferably, both the sealing cap and the sealing tube are made of transparent material.

[0020] The above design allows medical staff to clearly observe the internal condition through the transparent material, facilitating precise adjustment of the position of the sealing threaded column inside the sealing tube. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0026] like Figures 1-2 As shown: A laser-fixed anti-spray device includes a sealing cap 1, a sealing threaded post 6, and a rotary switch 7. The sealing cap 1 has a through hole 2, and an elastic membrane 3 is provided inside the through hole 2. The elastic membrane 3 is composed of several sealing flaps 4. The sealing flaps 4 are made of silicone material. The bottoms of the several sealing flaps 4 are integrally formed, and the tops of two adjacent sealing flaps 4 abut against each other. A sealing tube 5 is fixedly connected to the sealing cap 1. Both the sealing tube 5 and the sealing cap 1 are made of transparent material. A limiting ring 8 is provided outside the sealing tube 5, and several limiting grooves 10 are provided inside the sealing tube 5. A locking groove 9 matching the limiting ring 8 is provided inside the rotary switch 7. A limiting protrusion 11 matching the limiting groove 10 is provided on one side of the sealing threaded post 6, and the other side of the sealing threaded post 6 is threadedly connected to the rotary switch. The diameter of the sealing threaded post 6 is larger than the diameter of the through hole 2.

[0027] The specific implementation process is as follows:

[0028] First, the bottom of the sealing cap 1 is engaged with the operating channel of the ureteroscope. Rotate the rotary switch 7 to cause relative displacement between the rotary switch 7 and the sealing threaded post 6. At the same time, the limiting protrusion 11 on the sealing threaded post 6 and the limiting groove 10 in the sealing tube 5 limit each other, causing the sealing threaded post 6 to slide in the sealing tube 5, thereby causing the sealing threaded post 6 to separate from the through hole 2 in the sealing cap 1.

[0029] Secondly, medical staff insert surgical instruments through the through-hole 2 into the operating channel of the ureteroscope to treat the patient. During this process, several sealing flaps 4 are tightly attached to the surgical instruments to ensure the sealing of the ureteroscope operating channel.

[0030] Finally, after the surgical instruments have been used, the rotary switch 7 is turned again to make the sealing threaded post 6 slide, thereby sealing the through hole 2 and flushing through the flushing channel of the ureteroscope.
