Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to an innovative tip cap for an endoscope. Background Art

[0002] The endoscope tip cap is a medical device that is usually used in combination with a dedicated endoscope and is used to assist in observing the digestive tract wall and performing clinical operations under the supervision of a doctor in a medical institution.

[0003] The endoscope tip cap has a conical cap mouth, which is convenient for flushing and operation, has moderate elasticity, and a smooth surface, which can reduce damage to tissues. Its main uses include auxiliary hemostasis treatment, foreign body removal, magnified endoscopic examination, improved tangent position, and endoscopic imaging observation of lesions in difficult areas. In addition, it can also open the gaps in the mucosal layer and provide sufficient working space for cutting, coagulation, and blunt separation. In narrow places where foreign bodies are retained, the endoscope tip cap can provide a wide and stable space to facilitate the removal of foreign bodies, while reducing the psychological burden of the operator and shortening the time for foreign body removal.

[0004] When using the current tip cap of the endoscope, the doctor can only operate through the built-in forceps hole in the endoscope, which can be widely used in common gastrointestinal endoscopic examinations and treatment surgeries, such as EMR and ESD surgeries. Simply relying on a forceps hole in the endoscope to operate surgical instruments will result in low surgical efficiency. Utility Model Content

[0046] The center line of the side hole 22 intersects with the center line of the eyepiece 41 in the endoscope 4 , and the intersection point is located at the front end of the cap body 1 .

[0047] In this embodiment, the inner hole diameter of the channel tube 3 is 2.8 mm, 3.2 mm or 3.7 mm. The channel tube 3 serves as a secondary clamp channel hole, and the clamp channel hole 42 in the endoscope 4 serves as a main clamp channel hole. Both clamp channel holes can pass the instrument 5, which facilitates the doctor to perform surgical operations efficiently.

[0048] Specifically, as an optional implementation in this embodiment, Figure 1 Figure 2 As shown, a guiding inclined surface 23 is disposed at the front end of the tube body 2 , and the front end of the guiding inclined surface 23 transitions to the front end of the cap body 1 .

[0049] The outer wall of the tube body 2 is provided with a guiding slope 23, and the rear side of the guiding slope 23 is a flat surface. Through the guiding slope 23, the flanged tip cap is inserted into the human body cavity, and the surface is smooth and transitional, which reduces damage to the human body.

[0050] Specifically, as an optional implementation in this embodiment, Figure 1 Figure 2 As shown, the outer wall of the cap body 1 is a conical structure.

[0051] The tapered shape facilitates insertion into the human body cavity.

[0052] Specifically, as an optional implementation in this embodiment, the channel tube 3 and the endoscope 4 are fixed in sections by using tape.

[0053] Specifically, as an optional implementation in this embodiment, Figure 3 As shown, the front end of the channel tube 3 extends into the side hole 22, and the side hole 22 and the fixing hole 21 are connected and fixed.

[0054] In this embodiment, the fixing hole 21 and the side hole 22 are designed as one piece, with a smooth transition, so as to facilitate firm fixation with the channel tube 3. After fixation, the inner hole of the channel tube 3 is smooth and unobstructed.

[0055] Specifically, as an optional implementation in this embodiment, Figure 1 Figure 2As shown, the side hole 22 has an inclination of 15-45°. The inclination of the side hole 22 enables the instrument 5 to appear accurately within the field of vision.

[0056] Specifically, as an optional implementation in this embodiment, Figure 1 Figure 2 As shown, an annular groove 6 is provided at the front end of the tip cap of this embodiment, and the annular groove 6 is distributed outside the cap body and the tube body.

[0057] The tip cap is installed at the front end of the endoscope during operation, and the annular groove 6 can be conveniently inserted into the rope of the nylon rope or the metal wire of the snare, so that the rope or the metal wire can enter the human body together with the endoscope to complete the polypectomy operation.

[0058] Specifically, as an optional implementation in this embodiment, Figure 5 As shown, the rear end of the channel tube 3 is connected to the handle assembly 7, a main hole 71 and a side hole 72 are provided in the handle assembly 7, the front end of the main hole 71 is sealedly connected to the rear end of the channel tube 3, and the rear ends of the side hole and the main hole 71 are connected to the end cap. During use, the side hole can be connected to a syringe 74, and water is injected into the channel tube 3 through the syringe 74, so that the front end cap of this embodiment has a water injection function.

[0059] The innovative tip cap for endoscope of the utility model adds a channel tube 3 in the tip cap to serve as the front channel auxiliary hole for surgical instruments, which facilitates the entry of conventional instruments and forms a dual channel function with the forceps channel hole 42 in the endoscope 4, facilitating surgical operations and improving surgical efficiency.

[0060] The method of using the innovative end cap for endoscope of the utility model is as follows:

[0061] 1) Preoperative preparation:

[0062] 1.1 Fix the tip cap on the end of the endoscope 4 and adjust it to a suitable direction so that the outlet direction of the channel tube 3 is aligned with the outlet direction of the clamp channel hole;

[0063] 1.2 Place the channel tube 3 and the endoscope 4 straight and fix them in sections with tape;

[0064] 2) Operation steps: Take ESD surgery as an example;

[0065] 2.1 Insert the endoscope 4 to the lesion site according to the conventional gastroenteroscopy insertion steps;

[0066] 2.2 Perform marking, injection, incision and stripping operations according to normal ESD surgical procedures;

[0067] During the operation, an injection needle can be inserted through the channel tube 3, which is convenient for performing submucosal injection at any time, avoiding repeated replacement of instruments 5 (incision knife and injection needle) through a single channel hole, and improving the efficiency of the operation.

[0068] During the incision process, a foreign body forceps can be inserted through the channel tube 3, and the mucosal tissue can be pulled by the foreign body forceps to assist the mucosal stripping operation, thereby improving the surgical efficiency.
