Description

Technical Field

[0001] The utility model relates to an intracavitary surgical tubular accessory for a carbon dioxide laser therapeutic machine, belonging to the technical field of laser medical equipment. Background Art

[0002] Carbon dioxide laser therapy is widely used in medicine for a variety of treatment procedures and cosmetic surgeries. It uses CO2 laser to evaporate tissues and solidify surrounding tissues at the same time. In some surgical occasions that require entering the body cavity or the closed cavity of the pipeline, the use of carbon dioxide laser therapy during the operation will produce a large amount of thick and greasy smoke. After the smoke particles adhere to the lens and are burned by the laser, they will seriously damage the lens surface and quickly make the lens ineffective.

[0003] In existing carbon dioxide laser therapy devices, a single-tube reflector is usually used and installed in a closed cavity. Since there is no channel for smoke exhaust, the smoke generated after surgical cauterization fills the closed cavity and the lens will be seriously contaminated. In addition, the thick smoke obscures the laser transmission in the center of the tube, and may even cause the reflector to completely lose its reflective function, resulting in the inability to effectively proceed with the operation. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a tubular accessory for intracavitary surgery for a carbon dioxide laser therapeutic machine, which can circulate and discharge the smoke generated by the intracavitary surgery from the tube, thereby achieving the purpose of protecting the reflective lens.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0006] A tubular accessory for intracavitary surgery for a carbon dioxide laser therapy machine comprises an outer tube, an inner tube and a reflector which are coaxially mounted, and an air path gap is left between the tube walls of the outer tube and the inner tube.

[0007] The inner tube is a hollow structure, the top of the outer tube is provided with an interface seat, the interface seat is provided with an air inlet hole communicating with the inner tube, the wall of the outer tube is fixed with an air suction nozzle communicating with the air path gap, and the lower end of the wall of the outer tube is provided with a window.

[0008] The reflector is obliquely installed on the inner bottom of the outer tube through a reflector seat. The reflector is located below the inner tube and faces the window.

[0009] Furthermore, an outer tube end cap is screwed to the bottom end of the outer tube, and the reflector seat is placed on the outer tube end cap.

[0010] Furthermore, the reflector seat is a detachable reflector seat.

[0011] Furthermore, the air suction nozzle is fixedly connected to the upper end of the outer tube wall.

[0012] Furthermore, the angle between the reflector and the horizontal direction is 45°.

[0013] The working principle of the utility model is that air enters the bottom of the inner tube from the air inlet through the central channel of the inner tube, the outer tube and the inner tube form a double-layer tube structure, the gap between the two layers of tubes is the air inlet channel, the smoke generated by the surgical wound enters the tube from the window of the outer tube, and is sucked out from the interlayer gap of the double-layer tube through the suction nozzle, and the smoke is continuously brought out of the tube by the circulating airflow.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model discharges smoke through air circulation, effectively protects the reflective lens, ensures the normal operation, improves the stability of surgical light energy, and prolongs the service life of the reflective lens.

[0016] 2. The utility model facilitates the replacement of the reflector through the organic cooperation between the outer tube end cover and the detachable reflector seat, realizes the reuse of the entire surgical tubular accessory, and avoids the situation where the entire tubular accessory cannot be used due to damage to the reflector.

[0017] 3. The reflector of the utility model is arranged obliquely, and is particularly suitable for surgery on the side wall of the cavity when combined with the window on the side of the tube wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a structural schematic diagram of a preferred embodiment of the utility model. DETAILED DESCRIPTION

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the purpose, technical solution and advantages of the utility model will become clearer. It should be noted that the described embodiments are preferred embodiments of the utility model, but not all embodiments.

[0020] Combination Figure 1 As shown, a tubular accessory for intracavitary surgery for a carbon dioxide laser therapy machine comprises an outer tube 1, an inner tube 2 and a reflector 4 which are coaxially mounted, and an air path gap 3 is left between the tube walls of the outer tube and the inner tube. The inner tube 2 is a hollow structure, and an interface seat 8 is provided at the top of the outer tube 1, and an air inlet 8a which communicates with the inner tube 2 is provided on the interface seat 8. The upper end of the tube wall of the outer tube 1 is fixedly connected to an air suction nozzle 9 which communicates with the air path gap 3, and a window 6 is provided at the lower end of the tube wall of the outer tube. The reflector 4 is obliquely mounted on the bottom of the outer tube through a reflector seat 5, and the angle between the reflector 4 and the horizontal direction is 45°. The reflector is located below the inner tube 2 and faces the window 6, and can be used for surgery on the side wall of the cavity. In the figure, the upper arrow indicates the light inlet, and the lower arrow indicates that the light is emitted from the window, which is used for side surgery.

[0021] The bottom end of the outer tube is provided with an external thread, and the bottom end of the outer tube is screwed with an outer tube end cap 7, and the reflector seat 5 is placed on the outer tube end cap 7. The reflector seat 5 is preferably a detachable reflector seat to facilitate replacement and realize the reuse of the entire surgical tubular accessory.

[0022] The utility model allows air to enter the bottom of the inner tube from the air inlet through the central channel of the inner tube, and the outer tube and the inner tube form a double-layer tube structure. The gap between the two tubes is the air inlet channel. Smoke generated by the surgical wound enters the tube from the window of the outer tube and is sucked out from the interlayer gap of the double tube through the air suction nozzle. The smoke is continuously discharged from the tube through the circulating airflow.
