Description

Technical Field

[0001] This invention relates to a surgical device, and more particularly to a portable anorectal surgical aid device. Background Technology

[0002] Colorectal surgery is a clinical discipline that primarily treats tumors and injuries of the anus, rectum, and large intestine using surgery. It focuses on the diagnosis and treatment of hemorrhoids, anal fissures, anal fistulas, rectal prolapse, and colorectal cancer, and also covers complex conditions such as inflammatory bowel disease and congenital malformations. Symptoms include rectal bleeding, anal pain, and prolapse. Its scope extends beyond traditional hemorrhoid treatment to include a wider range of conditions, including sexually transmitted diseases.

[0003] Traditional anorectal endoscopes often lack effective guidance mechanisms, making it difficult to insert the probe smoothly and accurately to the target location, increasing the difficulty of the operation and patient discomfort. Secondly, the complex internal environment of the anorectal region, including mucus, blood, and other secretions, can obstruct the camera's view, leading to decreased image clarity and affecting the doctor's observation and judgment of lesions. Furthermore, in low-light environments, ordinary lighting is insufficient to provide adequate illumination, further limiting image quality. Moreover, to maintain a clear field of view, frequent cleaning or rinsing of the lens is necessary, which is not only time-consuming but may also lead to operational interruptions, increasing surgical risks.

[0004] Taking Chinese patent CN212879260U as an example, this patent proposes a multifunctional anorectal endoscope, belonging to the field of medical device technology. It includes at least a body and an endoscope lens. The endoscope lens is installed on the first end of the body and is connected to the first end of an endoscope line arranged inside the body. The second end of the endoscope line passes through the second end of the body along the central axis of the body. A drug delivery device, a cavity separation device, and a cleaning device are sequentially arranged on the outer periphery of the body along the direction from the first end to the second end of the body. Although this patent can realize independent anorectal cleaning and drug delivery, it still has the problems mentioned above, such as the inability of the camera to accurately penetrate and the inconvenience of cleaning the camera. Summary of the Invention

[0005] In order to overcome the shortcomings of current anorectal endoscopes, such as easy contamination of the lens after insertion into the patient's body, inconvenience of cleaning, and poor imaging quality in low light environments, this invention provides a portable anorectal surgery auxiliary device.

[0006] The technical solution is as follows: A portable anorectal surgery auxiliary device includes a handheld gun handle, a gun barrel, a probe tube, a probe, and a display screen. The front end of the handheld gun handle is connected to a hollow gun barrel. A guide hole is horizontally opened on the upper part of the handheld gun handle. The front end of the guide hole communicates with the rear end opening of the gun barrel, allowing the probe tube to slide into the gun barrel through the guide hole. The probe tube is connected to the front end of the probe tube. The display screen is fixed to the end face of the handheld gun handle for real-time display of images acquired by the probe. A camera is installed at the end of the probe, and the image image from the camera is transmitted to the display screen. A water pipe is fixed on the probe tube, and an annular nozzle is installed at the end of the water pipe for cleaning or rinsing the observation area. The annular nozzle is installed on the probe. An illumination lamp is installed at the front end of the probe to provide auxiliary lighting and ensure clear imaging even in low-light environments.

[0007] Furthermore, it also includes a spreading mechanism, which comprises a protective cover, a return spring, a double strut, a control ring, and a pusher. Several covers are arranged in a ring to form a conical protective cover. Each cover is slidably connected to the end of the gun barrel via a positioning post. The return spring is sleeved on the positioning post to connect the cover and the gun barrel. The double strut consists of two hinged rods, with the opposite ends of the two rods respectively hinged to the cover and the gun barrel. The pusher is slidably sleeved on the outside of the gun barrel, and a control ring is connected to the front end of the pusher. The control ring is located behind the double strut.

[0008] Furthermore, it also includes a fine-tuning mechanism, which includes a first gear shaft, a second gear shaft, and a limiting roller. The first gear shaft and the second gear shaft are rotatably connected to the handgrip. The inner cavity of the second gear shaft is provided with a concentrically arranged limiting roller, which makes frictional contact with the outer wall of the probe. The first gear shaft and the second gear shaft mesh.

[0009] Furthermore, a one-way sealing valve is provided at the end of the barrel. The one-way sealing valve is used to seal the front end of the barrel. Pushing the probe tube can open the one-way sealing valve through the probe, allowing the probe to extend from the front end of the barrel.

[0010] Furthermore, it also includes an auxiliary heating pipe, which is located on the outside of the barrel.

[0011] Furthermore, it also includes a guide cone, which is located on the upper part of the handgrip and is connected to the rear end of the guide hole. The guide cone is used to guide the probe so that the probe can slide smoothly into the barrel through the guide hole to achieve rapid loading.

[0012] Furthermore, it also includes a friction pad, with the handgrip of the gun covered by a friction pad.

[0013] Furthermore, it also includes a pad, with a pad provided at the bottom of the handgrip.

[0014] The beneficial effects are as follows: Regarding camera cleaning, this device incorporates a water pipe and a ring-shaped nozzle at the probe. When an external water source is connected, water flows through the pipe and is evenly sprayed from the ring-shaped nozzle, instantly cleaning the camera and preventing interference from mucus or dirt from the patient's intestinal wall. This ensures clear imaging without interrupting the cleaning process, significantly improving medical efficiency. Simultaneously, the device is equipped with a spreading mechanism, which protects the sealed probe, reducing friction damage to the intestinal wall, and can also slightly spread according to the patient's rectal condition, increasing internal space and improving probe throughput. This creates convenient conditions for subsequent medical procedures, combining practicality and innovation. Attached Figure Description

Detailed Implementation

[0024] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0025] Example: A portable anorectal surgery aid device, such as Figures 1-8 As shown, the device includes a handgrip 1, a barrel 2, a probe 3, a probe 4, and a display screen 5. The handgrip 1 is fitted with a friction pad 18, and a pad 19 is located at its bottom to improve grip stability and operational comfort. A hollow barrel 2 is fixedly connected to the front end of the handgrip 1. A guide hole is horizontally opened at the top of the handgrip 1, with its front end communicating with the rear opening of the barrel 2. The guide hole and barrel 2 are coaxially aligned, forming a straight channel to facilitate the probe 3 sliding into the barrel 2's inner cavity. The probe 3 is located inside the barrel 2 and the guide hole, and possesses a certain degree of flexibility. The probe 4 is detachably connected to the front end of the probe 3 for easy maintenance and replacement. The probe 4 is located inside the barrel 2. The probe 4, pushed by the probe tube 3, can extend into the rectum. The probe tube 3's flexible, adaptive intestinal curvature reduces patient discomfort and improves operational safety. The display screen 5, fixed to the upper surface of the handheld gun handle 1, displays images acquired by the probe 4 in real time. A camera 401 is installed at the end of the probe 4, electrically connected to the display screen 5. The image from the camera 401 is transmitted to the display screen 5. A water pipe 402 is fixed to the probe tube 3, and an annular nozzle 403 is installed at the end of the water pipe 402. The annular nozzles 403 are arranged in a ring array on the outer wall of the middle part of the probe 4, allowing for targeted flushing or cleaning of the observation area, effectively removing obstructions such as blood and mucus, and improving the clarity of the field of view. Multiple illumination lamps 404 are located at the front end of the probe 4, arranged in a ring around the camera 401 to provide auxiliary lighting, ensuring clear imaging even in low-light environments.

[0026] Furthermore, such as Figure 1 and Figure 4As shown, it also includes a spreading mechanism, which includes a protective cover 6, a return spring 7, a double support rod 8, a control ring 9, and a pusher frame 10. Several covers are arranged in a ring to form a conical protective cover 6. The outer surface of the protective cover 6 is smooth and made of skin-friendly material. Each cover has a chamfer at the front end to reduce damage to the tissue when inserted into the anus. Each cover has a positioning post inside. The outer surface of the front end of the gun barrel 2 has guide tubes spaced circumferentially at intervals equal to the number of covers. Each cover is slidably connected to the guide tube at the front end of the gun barrel 2 through its positioning post. The return spring 7 is sleeved on the positioning post, and its two ends are connected to the cover and the gun barrel 2. It is used to provide a restoring force after the protective cover 6 is unfolded, so that it retracts to the initial state. The double strut 8 consists of two hinged rods. The opposite ends of the two rods are hinged to the cover and the barrel 2, respectively. The hinged part in the middle of the double strut 8 extends to the rear. The pusher 10 is slidably sleeved on the outside of the barrel 2. The front end of the pusher 10 is connected to a control ring 9, which is located behind the hinge point in the middle of the double strut 8. When the pusher 10 is moved forward, the control ring 9 pushes the hinge point in the middle of the double strut 8 forward synchronously, causing the two rods to open outward, thereby driving the cover to expand radially and opening the protective cover 6. At this time, the return spring 7 is stretched and stores the return potential energy.

[0027] In a more preferred embodiment, such as Figure 1 , Figure 5 and Figure 6 As shown, it also includes a fine-tuning mechanism 11, which includes a first gear shaft 12, a second gear shaft 13, and limiting rollers 14. The first gear shaft 12 and the second gear shaft 13 are rotatably connected to the handgrip 1. The first gear shaft 12 is located below the second gear shaft 13. The first gear shaft 12 and the second gear shaft 13 mesh to realize power transmission. The second gear shaft 13 is set as a hollow structure, and each end of its interior is provided with a set of limiting rollers 14. Each set contains four limiting rollers 14. The four limiting rollers 14 in each set are evenly spaced along the circumferential direction of the inner wall of the second gear shaft 13. The outer surface of the limiting rollers 14 is... The probe 3 has an annular groove that matches its outer diameter. These limiting rollers 14 fit tightly against the outer wall of the probe 3 through the annular groove, effectively increasing the contact area. During the probe 3's back-and-forth movement, the limiting rollers 14 provide stable guiding support, ensuring smooth sliding. A knob is located at the rear end of the first gear shaft 12. After the probe 4 is inserted into the patient's intestine, the operator can rotate the knob to control the rotation of the first gear shaft 12, which in turn drives the rotation of the second gear shaft 13. Due to the friction between the limiting rollers 14 and the outer wall of the probe 3, the probe 3 rotates synchronously, thus achieving fine adjustment of the probe 4's angle. In this embodiment, the speed ratio of the first gear shaft 12 to the second gear shaft 13 is 5:1, which allows for fine-tuning of the probe 4's rotation, facilitating more precise and meticulous medical procedures for patients.

[0028] Furthermore, such as Figure 7 As shown, a one-way sealing valve 15 is provided at the front end of the barrel 2. This one-way sealing valve 15 consists of multiple fan-shaped flexible baffles arranged in a ring to form a complete disc-shaped structure, which tightly seals the opening at the front end of the barrel 2. When the probe 3 is advanced forward, the probe 4 at its front end contacts and presses against the flexible baffles, causing them to undergo elastic deformation to the forward side, thereby opening the one-way sealing valve 15 and allowing the probe 4 to smoothly extend out of the barrel 2 and enter the anorectal cavity. Without external force, the flexible baffles automatically reset and close due to their own elasticity, restoring the sealing state. When closed, the one-way sealing valve 15 can effectively isolate the external environment, providing physical protection for the probe 4 and preventing mucus, blood, or other contaminants from the patient's intestinal cavity from adhering to the lens surface, ensuring imaging clarity and equipment cleanliness.

[0029] Furthermore, such as Figure 1 , Figure 4 and Figure 7 As shown, it also includes an auxiliary heating tube 16, which is located on the outside of the tube 2. The auxiliary heating tube 16 is an electric heating tube that can preheat the tube 2 before medical operations. Before the operator inserts the tube 2 into the patient's anorectal area, the auxiliary heating tube 16 is activated, allowing the generated heat to be conducted through the tube wall of the tube 2 to the water pipe 402 and the probe inside. This preheating function can effectively avoid patient discomfort or local muscle spasms caused by the initial temperature of the device being too low, improving the comfort and safety of the examination or surgical process. At the same time, moderate heating also helps to maintain the temperature of the irrigation fluid, further optimizing the operating experience and clinical results.

[0030] Furthermore, such as Figure 1 and Figure 5 As shown, it also includes a guide cone 17, which is located on the upper part of the handgrip 1. The guide cone 17 is connected to the rear end of the guide hole. The guide cone 17 is used to guide the probe 3 so that the probe 3 can smoothly slide into the barrel 2 through the guide hole to achieve rapid loading.

[0031] In the initial state, the protective cover 6 is tightly connected under the action of the return spring 7, forming a conical structure with a closed front end. At this time, the control ring 9 is located away from the two-link strut 8. When using this anorectal surgery auxiliary device, the operator first holds the handheld gun handle 1 with the friction pad 18 attached, and brings the protective cover 6 at the front end of the device close to the patient's anus. Then, the operator pushes the pusher 10 forward, so that the control ring 9 contacts and pushes the hinged part in the middle of the two-link strut 8. This action forces the two struts to open outward, and through the hinged relationship, pulls each cover radially along the guide tube at the front end of the gun barrel 2, thereby opening the protective cover 6 into a trumpet shape and gently dilating the anus; during this process, the return spring 7 is stretched and stores the retraction potential energy. At the same time, if it is necessary to improve the patient's comfort, the auxiliary heating pipe 16 can be activated in advance to moderately heat the gun barrel 2, so that the gun barrel 2, the internal water pipe 402 and the probe 4 are preheated to close to the body temperature, avoiding muscle spasms caused by low temperature stimulation.

[0032] Next, the operator pushes the probe tube 3 forward via the guide cone 17. The probe tube 3 slides smoothly into the inner cavity of the gun barrel 2 along the guide hole, and its flexibility adapts to the intestine with a small degree of bending. When the probe 4 reaches the front end of the gun barrel 2, its end presses against the flexible baffle of the one-way sealing valve 15, causing it to elastically deform forward and open the channel, allowing the probe 4 to smoothly extend into the anorectal cavity. At this time, the camera 401 at the end of the probe 4, assisted by multiple surrounding lights 404, acquires images of the inside of the intestine in real time, and transmits the images to the display screen 5 on the top of the handheld gun handle 1 via electrical connection, allowing the operator to clearly observe the lesion area. If the field of vision is obstructed by blood, mucus, etc., flushing fluid can be delivered through the water pipe 402 fixed on the probe tube 3, and sprayed circumferentially from the middle of the probe 4 by the annular nozzle 403 to clean the observation area in a targeted manner, quickly restoring a clear field of vision.

[0033] Once the probe 4 is inserted into the target position, if the observation angle needs to be adjusted, the operator can rotate the knob at the rear end of the first gear shaft 12 in the fine-tuning mechanism 11. Since the first gear shaft 12 and the second gear shaft 13 mesh with each other at a reduction ratio of 5:1, the second gear shaft 13 rotates slowly. The limiting roller 14 circumferentially set on its inner wall drives the probe tube 3 to rotate synchronously by the friction between it and the outer wall of the probe tube 3, thereby realizing the fine angle adjustment of the probe 4, which is convenient for precise positioning or operation.

[0034] After the operation is completed, the operator first stops rotating the knob, causing the fine-tuning mechanism 11 to stop functioning. Then, the operator pulls the probe tube 3 backward, and the probe 4 exits the rectum and retracts into the gun barrel 2. The flexible baffle of the one-way sealing valve 15 automatically closes due to its own elasticity without external pressure, restoring the sealing state and effectively isolating external contaminants, protecting the camera 401 and internal pipelines from contamination. Subsequently, the push frame 10 is released, and the two struts 8, having lost their forward thrust, automatically retract under the restoring force of the return spring 7, causing each cover to slide inward along the guide tube, and the protective cover 6 recloses to its initial conical structure. The auxiliary heating pipe 16 is de-energized and cooled, and the entire machine returns to its initial standby state, facilitating cleaning, disinfection, or next use.

[0035] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
