Abstract
Description
Technical Field
[0001] The utility model relates to surgical equipment, in particular to an anal peephole capable of removing smoke. Background Art
[0002] Rectal tumors are common diseases in the gastrointestinal tract. When the lesion is located in the middle and upper part of the rectum, surgery can be performed through the abdomen. When the lesion is located in the lower part of the rectum, surgery can be performed through the anus. When the electric knife is used during surgery, a large amount of smoke will be generated, blocking the surgical field of view. It is necessary to use a smoking device to smoke and use an aspirator to remove the smoke. When using it, the smoking device (suction head) needs to be inserted into the position where the smoke is generated for suction. However, the operating space for transanal surgery is very limited. The suction head of the smoking device will not only affect the operation of the scalpel, but also block the line of sight to a certain extent. Therefore, smoking operations may cause the surgical process to be suspended and increase the operation time. Utility Model Content
[0003] The utility model aims to provide an anal peephole with a smoking passage.
[0004] An anal peephole includes a trumpet-shaped outer expansion section; and a tubular inner expansion section for inserting into the anus, one end of which is connected to the narrower end of the outer expansion section. The outer expansion section and the inner expansion section are formed with a hollow interlayer connected up and down as a smoking passage. The opening of the interlayer of the outer expansion section serves as the outlet of the smoking passage and is located at the wider end of the outer expansion section or the outer side surface close to the wider end. The opening of the interlayer of the inner expansion section serves as the entrance of the smoking passage and is located on the inner side surface of the inner expansion section and is in the shape of a narrow and long slit.
[0005] During the operation, the tubular inner expansion section of the anoscope will be inserted into the anus, and the doctor's scalpel will perform the operation on the exposed rectum below the inner expansion section. The smoke generated can be promptly removed through the smoking channel located in the anoscope, effectively preventing the smoke from blocking the surgical field of view. Since there is no need to place the suction head of the external smoking device on the inside of the anoscope, the doctor's operation will not be interrupted, thereby improving the efficiency of the operation. Since the smoking channel is formed by a hollow interlayer located in the anoscope, the anoscope can be formed in one piece, which is easy to manufacture and can remain stable during use. Since the entrance of the smoking channel is located on the inner side of the inner expansion section, rather than the end of the inner expansion section, it is not easy to be blocked by the severed rectal wall, nor is it easy to suck tissue fluid, thus ensuring that the smoke channel is unobstructed. Since the entrance is in the shape of a narrow and long slit, smoke can be extracted over a large range, and the smoking efficiency is high.
[0006] Preferably, the inlet is substantially parallel to the free end of the inner expansion section, and is 1 to 1.5 cm away from the end of the inner expansion section connected to the outer expansion section 11, which ensures uniform suction at the inlet and high smoking efficiency.
[0007] As an embodiment, the anoscope comprises two smoking passages which are not connected to each other and are arranged rotationally symmetrically or axisymmetrically relative to the central axis of the anoscope, and the distance between the entrances of the two smoking passages is 0.5 to 1.5 cm, which can ensure a large smoking range and high smoking efficiency.
[0008] As an implementation method, two ports of a Y-shaped hose are respectively connected to the outlets of the two smoking channels, and the other port is adapted to the suction nozzle of the external smoking device. In this way, the effect of double-sided large-scale smoking can be achieved by using only one external smoking device.
[0009] As an implementation mode, the outlet of the smoking passage is adapted to the suction nozzle of an external smoking device, so that it can be detachably connected to the suction nozzle of the external smoking device, thereby facilitating the connection with the external smoking device.
[0010] As an implementation mode, the outlet of the smoking passage is connected to an interface adapter, and the interface adapter is adapted to the suction nozzle of an external smoking device, thereby facilitating the connection with the external smoking device.
[0011] As an implementation mode, the outlet of the smoking passage is connected to a hose, and the hose can be sleeved on the suction nozzle of an external smoking device, so as to facilitate the connection with the external smoking device.
[0012] As an implementation mode, the outlet of the smoking passage can be used for inserting a nozzle of an external smoking device, thereby facilitating connection with the external smoking device.
[0013] As an implementation mode, a hollow latex ring is inserted into the outlet of the smoking passage to facilitate connection with an external smoking device.
[0014] As an implementation method, the anoscope is made of a transparent material to optimize the surgical field.
[0015] The anoscope of the utility model has a smoking channel formed by a hollow interlayer, so that the doctor can timely remove the smoke generated during the operation through the smoking channel, effectively preventing the smoke from blocking the surgical field of view. Since there is no need to place the suction head of the external smoking device inside the anoscope, the doctor's operation will not be interrupted, thereby improving the efficiency of the operation. Since the smoking channel is formed by the hollow interlayer located inside the anoscope, the anoscope can be integrally formed, which is convenient to manufacture and can remain stable during use. Since the entrance of the smoking channel is located on the inner side of the inner expansion section, rather than the end of the inner expansion section, it is not easy to be blocked by the rectal wall after the severance, and it is not easy to suck in tissue fluid, thereby ensuring that the smoke channel is unobstructed, and the visual field area exposed by the anoscope will not be reduced and the operating space will not be occupied. Since the entrance is in the shape of a narrow and long slit, smoke can be extracted over a large range to prevent the smoke from continuing to rise, and the smoking efficiency is high.

[0019] The utility model is further described in detail below with reference to specific embodiments and accompanying drawings. Embodiment 1:
[0020] like Figure 1 As shown, in the first embodiment, the anoscope 10 of the utility model mainly includes a trumpet-shaped outer expansion section 11 and a tubular inner expansion section 12. In use, the inner expansion section 12 will be inserted into the anus, and the outer expansion section 11 will be left outside the body. One end of the inner expansion section 12 is connected to the narrower end of the outer expansion section 11, preferably integrally formed, and is a transparent, hard plastic product.
[0021] The outer expansion section 11 and the inner expansion section 12 are formed with a hollow interlayer connected up and down as a smoking passage. Figure 1 In the figure, the boundary of the hollow interlayer is shown by a dotted line, and the smoking channel is indicated by a reference numeral 13. In this embodiment, two smoking channels 13 that are not connected to each other are provided, and the two are rotationally symmetrically arranged relative to the central axis of the anoscope 10 (in this embodiment, they are also axisymmetrically arranged). The opening of the interlayer of the outer expansion section 11 serves as the outlet 131 of the smoking channel 13, and is located at the wider end of the outer expansion section 11. The opening of the interlayer of the inner expansion section 12 serves as the entrance 132 of the smoking channel 13, and is located on the inner side of the inner expansion section 12.
[0022] In order to improve the efficiency and range of smoking, the inlet 132 is in the shape of a narrow slit, preferably substantially parallel to the free end 121 of the inner expansion section 12. Moreover, the distance between the inlet 132 and the end of the inner expansion section 12 connected to the outer expansion section 11 is preferably 1 to 1.5 cm. Generally, the inner expansion section 12 of the anal peephole is 2 to 3 cm long. When the distance between the inlet 132 and the end of the inner expansion section 12 connected to the outer expansion section 11 is 1 to 1.5 cm, a large amount of smoke generated during an electric scalpel surgery can be transversely sucked into the smoking channel at the moment of rising, which will not reduce the exposed field of view of the anal peephole and hinder the operation. The use of a narrow slit-shaped inlet substantially parallel to the free end 121 of the inner expansion section 12 can also make the suction utilization rate of the external smoking device high, because although the inlet is long, the shape of the slit makes its pressure drop small.
[0023] In this embodiment, the distance between the two inlets 132 (i.e., the distance between the adjacent ends of the two inlets) is 0.5 to 1.5 cm. In this way, the entire inner expansion section 12 is not entirely sandwiched, which ensures the overall strength and hardness of the inner expansion section 12, and makes the total inlet of the smoking channel cover as large an area as possible, maximizing the smoking range.
[0024] As described above, in this embodiment, the outlet 131 is arranged at the wider end of the expansion section 11, that is, at the free end of the expansion section 11. In this way, it will not affect the doctor's hand operation, and will not be clamped between the patient's skin and the anoscope 10. The size of the outlet 131 is small, and it can be designed to be adapted to the suction nozzle of the external smoking device, so that it can be detachably connected to the suction nozzle of the external smoking device directly. The outlet 131 can also be connected to the suction nozzle of the external smoking device through an interface adapter. For example, the interface adapter can be a hollow silicone interface that is inserted into the outlet 131 and can be tightly clamped. The free end of the silicone interface can be connected to the suction nozzle of the external smoking device, so that the smoking channel 13 and the suction nozzle of the external smoking device are connected by the hollow silicone interface. The outlet 131 can also be connected to the suction nozzle of the external smoking device through a hose. For example, one end of the hose is tightly inserted into the outlet 131, and the other end is sleeved on the suction nozzle of the external smoking device. Alternatively, a hollow latex ring may be inserted into the outlet 131, thereby allowing the suction nozzle of the external smoking device to be directly inserted into the hollow latex ring inside the outlet 131 to achieve a sealed connection.
[0025] In this embodiment, as Figure 2 The two ports 21 and 22 of the Y-shaped hose 20 are respectively connected to the outlets 131 of the two smoking channels 13, and the other port 23 is used to fit the suction nozzle of an external smoking device (not shown). Thus, efficient smoke extraction can be achieved by using only one external smoking device. The external smoking device can be placed under the operating table, which is convenient to use and not easy to interfere with the surgical operation. Embodiment 2:
[0026] like Figure 3 As shown, the structure of the anoscope 30 of the second embodiment is basically the same as that of the first embodiment, and the difference between the second embodiment and the first embodiment is mainly that the two outlets 131' are arranged on the outer side of the outer expansion section 11' close to the wider end. The outlet 131' is connected to a hose or an interface adapter 14. The outlet 131' is arranged on the outer side of the outer expansion section 11' close to the wider end to avoid interference with the doctor's surgical operation to the greatest extent. The hose or the interface adapter 14 can be made of soft skin-friendly materials to minimize the discomfort of the patient.
[0027] In the above two embodiments, the inlet of the smoking channel is substantially parallel to the free end of the inner expansion section. It is understandable that in other embodiments, the inlet may be slightly inclined, for example, the inclination angle relative to the free end of the inner expansion section is within 20 degrees, and the desired effect can be achieved without causing the suction force at the lowest end of the inlet to drop too much to prevent the smoking effect.
[0028] In the above two embodiments, two symmetrical smoking passages are provided. It is understandable that in other embodiments, the smoking passages may not be symmetrical, for example, both are provided close to one side, as long as the expected smoking effect is achieved.
[0029] In the above two embodiments, two smoking passages are provided. It is understandable that in other embodiments, the number of smoking passages is not limited thereto, and may also be one or three.
[0030] In the above two embodiments, the anoscope is made of transparent material. It can be understood that in other embodiments, the anoscope can be partially transparent or translucent. Preferably, the inner expansion section is transparent or translucent, which can achieve the purpose of optimizing the surgical field.
[0031] Although the utility model is described in conjunction with the above specific embodiments, it is obvious that those skilled in the art can make many substitutions, modifications and changes based on the above content. Therefore, all such substitutions, improvements and changes are included in the spirit and scope of the appended claims.
