Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a threaded instrument conduction device for an endoscope and its method of use. Background Technology

[0002] As is well known, an endoscope is a diagnostic instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It is an instrument containing an image sensor, optical lens, light source, and mechanical devices, and can be inserted into the stomach through the mouth or other natural orifices. Endoscopes can visualize lesions that X-rays cannot, making them extremely useful for doctors. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the stomach and formulate the best treatment plan accordingly.

[0003] Currently, most endoscopes consist of a tubular body with an image sensor and illumination device at the end, and one or two biopsy channels along the body. In practical applications, when surgery is performed using the endoscope, surgical instruments need to be inserted. These are typically inserted through the biopsy channels, but sometimes additional instruments are required, or instruments cannot be simultaneously inserted through the biopsy channels to reach the surgical site. When different surgical instruments are used simultaneously, they must be quickly changed through the biopsy channels, making it impossible to coordinate several instruments for the entire procedure. The process of inserting and removing instruments prolongs the surgery time and increases surgical risks, potentially causing repeated stimulation and discomfort to the patient. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a threaded instrument transmission device for endoscopes and a method of using it.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An endoscope threaded instrument delivery device includes an automatically spirally rewindable roll and a collar for fitting onto the endoscope lens. The roll is gradually spirally wound and then assembled onto the outer wall of the endoscope. The collar is connected to the bottom end of the roll. Multiple inclined through holes are formed on the side of the roll. After the roll is spirally wound, the through holes are aligned with each other to form at least one delivery channel for delivering the instrument. The collar is provided with a discharge channel at the corresponding position of the delivery channel.

[0006] Preferably, the side of the roll is also provided with a limiting protrusion and a limiting groove. Each time the roll is spiraled around once, the limiting protrusion is inserted into the corresponding limiting groove, so that the spiral angle of the roll remains unchanged.

[0007] Preferably, the two sides of the roll are respectively provided with sloping surfaces, one of the sloping surfaces on both sides of the roll facing outward and the other facing inward, and the slope of the sloping surfaces is 30°-65°.

[0008] Preferably, the limiting protrusion and the limiting groove are located 1 mm away from the side of the conveying channel.

[0009] Preferably, the inner surface of the through hole is coated with a medical lubricant.

[0010] Preferably, the collar and the roll are marked with different colors at different through holes, and each color mark corresponds to a single conveying channel.

[0011] Preferably, the collar and the roll are marked with different characters at different through holes, and each character mark corresponds to a single conveying channel.

[0012] Preferably, the collar has a notch, through which it is fitted onto the lens of the endoscope, and the collar has a clearance hole for avoiding the endoscope probe.

[0013] A method of using a threaded instrument conduction device for an endoscope includes the following steps: S1. By placing the loop on the lens and the endoscope body, it can be pushed close to the endoscope operating section without affecting the surgical operation; S2. The endoscope with the assembled collar is gradually inserted into the human body. During insertion, the roll is operated while pushing the endoscope and spirally rolling the roll. The roll is gradually attached to the outer wall of the endoscope from the collar. An inward pushing force is applied to the roll, and the roll's own self-winding tendency makes the attachment more stable. Each time the roll rotates, the limiting protrusion and limiting groove on the roll form an interlocking limit, so that the two adjacent sides of the roll form an upper and lower inclined plane, with the front side pressing against the back side. This ensures the stability of the delivery channel and prevents the roll from shifting when the endoscope turns, thus preventing surgical instruments from passing through the two adjacent sides and causing surgical failure. S3. After the endoscope is pushed to the surgical site, the end of the roll outside the body needs to be supported to keep it from moving. At this time, each through hole is aligned with each other to form a delivery channel. The surgeon can push the instruments that need to be transported one by one through this delivery channel and discharge them to the surgical site from the discharge channel of the collar. S4. After the surgery is completed, the entire device can be withdrawn along with the endoscope.

[0014] By adopting the above-mentioned solution, this invention uses an automatically spirally retractable roll attached to the periphery of the endoscope. After the roll spirals, the through holes on the roll align with each other to form one or more transport channels. Surgical instruments can then be pushed through these channels, avoiding contact between the instruments and the human body during the process, thus achieving a more effective and safer delivery of surgical instruments. At the same time, the entire assembly is not fixedly connected to the endoscope, allowing for easy disassembly and assembly at any time, which facilitates production and postoperative cleaning and disinfection.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection.

[0025] like Figures 1 to 7 As shown, this embodiment provides a threaded instrument delivery device for an endoscope, including an automatically spirally rewindable roll 1 and a collar 2 for fitting onto the endoscope lens 100. The roll 1 is gradually spirally wound and then assembled onto the outer wall of the endoscope. The collar 2 is connected to the bottom end of the roll 1. The side of the roll 1 has multiple inclined through holes 11. After the roll 1 is spirally wound, the through holes 11 are aligned with each other to form at least one delivery channel 3 for delivering instruments. The collar 2 is provided with a discharge channel 21 at the corresponding position of the delivery channel 3.

[0026] This embodiment mainly uses an automatically spirally retractable roll 1 attached to the periphery of the endoscope. After the roll 1 spirals, the through holes 11 on the roll 1 align with each other to form a transport channel 3. Surgical instruments can then be pushed through the transport channel 3, avoiding contact between the surgical instruments and the human body during the pushing process, thus achieving a more effective and safer transfer of surgical instruments. At the same time, the whole assembly is not fixedly connected to the endoscope, and can be disassembled and assembled at any time, which facilitates production and postoperative cleaning and disinfection operations.

[0027] The specific steps for using it are as follows: S1. By placing the collar 2 on the lens 100 and the endoscope body, it can be pushed close to the endoscope operating section without affecting the surgical operation. S2. The endoscope with the assembled collar 2 is gradually inserted into the human body. During the insertion process, the roll 1 needs to be operated. While pushing the endoscope, the roll 1 is spirally rolled so that the roll 1 gradually attaches to the outer wall 102 of the endoscope from the collar 2. The roll 1 is also given an inward pushing force, and the automatic rewinding tendency of the roll 1 makes the attachment more stable. S3. After the endoscope is pushed to the surgical site, the end of the roll 1 outside the body (endoscope operating section) needs to be supported to keep it stationary. At this time, each through hole 11 is aligned with each other, forming a transport channel 3. The surgeon can then push the instruments to be transported one by one through this transport channel 3 and discharge them to the surgical site through the discharge channel 21 of the collar 2. The inner diameter of the roll is the same as the diameter of all endoscopes (including gastroscopes, colonoscopes, bronchoscopes, laryngoscopes, nasopharyngoscopes, otoscopes, hysteroscopes, and other medical fiber endoscopes). Its length is the same as the length of the aforementioned fiber endoscope. S4. After the surgery is completed, the entire device can be withdrawn along with the endoscope.

[0028] Furthermore, to ensure that the roll 1 can more accurately attach to the endoscope during use, specifically in step S2, the side of the roll 1 in this embodiment is also provided with a limiting protrusion 12 and a limiting groove 13. Each time the roll 1 spirals once, the limiting protrusion 12 inserts into the corresponding limiting groove 13, maintaining the spiral angle of the roll 1. This creates upper and lower inclined surfaces on the two adjacent sides of the roll 1, with the rear side pressing against the front side, ensuring the stability of the transport channel 3. This prevents the roll 1 from shifting when the endoscope turns, thus preventing surgical instruments from passing between adjacent sides and causing surgical failure. This also ensures that the through holes 11 are aligned, guaranteeing the normal formation of the transport channel 3.

[0029] Furthermore, to improve the side fit of the film after spiral winding, the two sides of the film 1 are respectively provided with inclined surfaces 14. One of the inclined surfaces 14 on each side of the film 1 faces outward, and the other faces inward. That is, every 360 degrees of rotation, adjacent films 1 form mutually fitting inclined surfaces 14, with a slope between 30 and 65 degrees. The mirror end is the front inclined surface (vertical to the top of the endoscope) and covers the operating part end, which is the rear inclined surface (vertical to the bottom of the endoscope) (a slope of 30 degrees is recommended). The span of the inclined surfaces 14 needs to have a certain length, allowing sufficient space for the film 1 to move vertically, and ensuring that the endoscope is located at a turning point in the body, preventing gaps in the sheath that could cause the instrument to slip out and lead to accidents. Figure 6-7 As shown.

[0030] Furthermore, to ensure that the limiting effect of the limiting protrusion 12 and the limiting groove 13 is optimal, the limiting protrusion 12 and the limiting groove 13 in this embodiment are located 1 mm away from the side of the conveying channel 3.

[0031] Furthermore, to improve the smooth delivery of surgical instruments, the inner surface of the through hole 11 in this embodiment is coated with medical lubricant, which can better push the surgical instruments along the delivery channel 3.

[0032] Furthermore, in this embodiment, the collar 2 and the roll 1 are marked with different colored symbols 4 at different through holes 11, with each single-color symbol 4 corresponding to a single transport channel 3. Alternatively, the collar 2 and the roll 1 can be marked with different characters 4 at different through holes 11, with each character symbol corresponding to a single transport channel 3. In this embodiment, by setting corresponding symbols, each transport channel 3 can be defined, and the endoscope has its own orientation markers, such as... Figure 5 As shown, and depending on the screen design, the camera auxiliary markings 101 can be different colors or different characters, which can be adapted to the markings in this embodiment. In this way, when the endoscope lens 100 is inserted into the human body, the endoscope will have an angle and orientation change. At this time, the doctor cannot determine whether the direction detected by the endoscope lens 100 is consistent based on the original insertion position. Therefore, when the location of the affected area A is detected, the doctor can directly insert the surgical instruments into the delivery channel 3 corresponding to its position. In this way, the transmitted instruments can be accurately discharged from the delivery channel 3 closest to the affected area A, which facilitates the faster performance of related surgeries.

[0033] Furthermore, regarding the structure of the collar 2, in this embodiment, the collar 2 is provided with a sleeve opening 22. The collar 2 is fitted onto the lens of the endoscope through the sleeve opening 22, and the collar 2 is provided with a clearance hole for avoiding the endoscope probe 100. The collar 2 is made of soft rubber or shape memory metal, specifically transparent medical silicone. When the collar 2 is assembled onto the endoscope, the elasticity of the soft rubber material allows it to be securely clamped to the endoscope lens 100. The collar 2 can be open or ring-shaped, and can be integrated with the subsequent film roll 1 or separate. When separate, its mirror end has a side hole, and its operating end has a pin hole. The corresponding film roll 1 also has a matching pin, and assembly is formed by the pin and the pin hole.

[0034] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
