[0001] This invention relates to the field of laparoscopic auxiliary equipment technology, and in particular to a laparoscopic lens cleaning device, laparoscopic surgical instruments, and cleaning method. Background Technology

[0002] During laparoscopic surgery, surgeons rely on a laparoscope inserted into the body cavity to view the surgical area. During the procedure, the laparoscope may become contaminated with blood, bodily fluids, or other viscous substances, or it may fog up, affecting the surgeon's field of vision. Therefore, it is necessary to clean the laparoscope regularly.

[0003] There are two ways to clean the laparoscope lens. One is to remove the laparoscope from the body and then clean the lens. However, repeatedly removing the laparoscope not only prolongs the operation time but also increases the risk of potential infection. The other method is to install a cleaning device on the laparoscope and clean the lens using the device. This method does not require removing the laparoscope to complete the cleaning process. However, during laparoscopic surgery, it is necessary to maintain a pneumoperitoneum seal at all times. Therefore, the laparoscope and the abdominal paracentesis instrument need to be sealed. Installing a cleaning device on the laparoscope will affect the seal between the laparoscope and the abdominal paracentesis instrument.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] The purpose of this invention is to provide a laparoscopic lens cleaning device, abdominal surgical instruments, and cleaning method to solve the problems existing in the prior art. It can clean the laparoscopic lens without removing the laparoscope, and maintain a good seal between the laparoscope and the abdominal trocar after the laparoscope passes through the abdominal trocar.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] This embodiment provides a laparoscopic lens cleaning device, such as... Figure 1-7 As shown, it includes: a ventilation tube; the air inlet of the ventilation tube is connected to a gas source, and the laparoscope lens 24 is purged by the gas introduced into the ventilation tube; the ventilation tube is installed inside the abdominal surgical instruments.

[0041] Furthermore, the abdominal surgical instrument is a laparoscope 16; the laparoscope 16 also includes a laparoscope cannula 1; the laparoscope cannula 1 has a first installation channel 3 and a second installation channel 4, the first installation channel 3 and the second installation channel 4 are arranged side by side radially along the laparoscope cannula 1 and extend parallel to each other axially along the laparoscope cannula 1; the laparoscope 16 is fitted inside the first installation channel 3, and the laparoscope lens 24 extends out of the first installation channel 3; the second installation channel 4 is a ventilation pipe; one end of the ventilation pipe is connected to a gas source, and the other end is fixedly installed with a nozzle located on one side of the laparoscope lens 24; the nozzle is used to spray gas to purge the laparoscope lens 24; one end of the fixing clip 2 is fixedly connected to the laparoscope cannula 1, and the other end is fixedly connected to the laparoscope vertical rod; the outer peripheral surface of the laparoscope cannula 1 is sealed with the abdominal trocar 15.

[0042] As a specific implementation of this embodiment, in order to ensure the airtightness between the outer peripheral surface of the laparoscopic cannula 1 and the abdominal trocar 15, the laparoscopic cannula 1 is a cylinder with a smooth outer surface.

[0043] As a specific implementation method of this embodiment, such as Figure 2 As shown, in order to make the laparoscope 16 more stable in the first installation channel 4, a fixing shim 5 is fixedly installed in the first installation channel 4; the fixing shim 5 is made of soft polymer material, and when the laparoscope 16 is installed in the first installation channel 4, the fixing shim 5 and the laparoscope 16 are interference fit.

[0044] As a specific implementation of this embodiment, in order to ensure an airtight connection between the laparoscope 16 and the first mounting channel 4, the fixing gasket 5 is a circular fixing gasket; the circular fixing gasket is located between the laparoscope 16 and the first mounting channel 4; the outer side of the circular fixing gasket is sealed and fixedly connected to the first mounting channel 4, and the inner side of the circular fixing gasket is sealed and fitted to the laparoscope 16; by fixing the fixing gasket 5 in the first mounting channel 4, the laparoscope 16 and the first mounting channel 4 can be prevented from moving relative to each other, and the airtightness between the laparoscope 16 and the first mounting channel 4 can be guaranteed.

[0045] As a specific implementation of this embodiment, a plurality of fixing pads 5 are fixedly installed in the first installation channel 4 along its axial direction.

[0046] As a specific implementation method of this embodiment, such as Figure 1 As shown, a pressure stabilizing control device 9 is installed between the gas source and the ventilation pipeline. The pressure stabilizing control device 9 has a gas flow rate and velocity adjustment function. The flow rate and velocity of the gas entering the ventilation pipeline are regulated by the pressure stabilizing control device 9. After the gas in the gas source enters the pressure stabilizing control device 9, the gas with constant pressure and velocity is output by the pressure stabilizing control device 9, and then the gas is delivered to the ventilation pipeline.

[0047] As a specific implementation method of this embodiment, such as Figure 1 and 2 As shown, an air inlet side hole 8 is provided on the ventilation pipe; the air inlet side hole 8 is connected to the pressure stabilizing control device 9 through the air pipe 14; in order to ensure that the air pipe 14 is firmly connected to the ventilation pipe, the end of the air pipe 14 corresponding to the air inlet side hole 8 is inserted into the ventilation pipe from the air inlet side hole 8 and is bonded to the ventilation pipe; by bonding the air pipe 14 to the ventilation pipe, the connection between the air pipe 14 and the ventilation pipe can be made firm, and it will not detach from the ventilation pipe under the impact of air pressure. With the help of glue, a better sealing effect can be achieved, so that gas will not leak at the connection between the air pipe 14 and the ventilation pipe.

[0048] As a specific implementation of this embodiment, the pressure stabilizing control device 9 is equipped with a flushing foot switch 10; by stepping on the flushing foot switch 10, gas flows out from the pressure stabilizing control device 9; during the operation, because the doctor needs to hold surgical instruments and keep their hands clean to avoid infection of the wound, it is inconvenient to operate the flow or shut off of gas by hand. Therefore, the switch in this device is located at the bottom, and the flow or shut-off of gas is controlled by stepping on it; stepping on the flushing foot switch 10 allows gas to flow and purge the laparoscope lens 24, and lifting the foot shuts off the airflow.

[0049] As a specific implementation of this embodiment, the gas source is configured according to the operating room, and the gas source is divided into a gas cylinder type gas source 12 and a terminal type gas source; the pressure stabilizing control device 9 is provided with a gas source interface 11; the gas cylinder type gas source 12 is equipped with a pressure reducing valve 13, which is connected to the gas source interface 11; if the gas pressure in the gas cylinder type gas source 12 is too high, if it is directly connected to the gas source interface 11, the interface position is easy to loosen and fall off under the action of gas pressure. Therefore, a pressure reducing valve 13 is installed on the gas cylinder type gas source 12 to reduce the gas pressure before it is delivered to the pressure stabilizing control device 9, so as to avoid accidents caused by excessive pressure in the gas cylinder type gas source 12 during the operation; the terminal type gas source is provided centrally by the medical unit, and there are multiple terminal card interfaces in the operating room. The gas source interface 11 is connected to the terminal card interface in the operating room through the trachea.

[0050] As a specific implementation of this embodiment, the gas source includes medical carbon dioxide, medical nitrogen or medical purified air. After the medical gas enters the pressure stabilizing control device 9, the pressure and flow rate of the gas used for cleaning are kept constant through the adjustment of the pressure stabilizing control device 9 to meet the cleaning requirements.

[0051] As a specific implementation method of this embodiment, such as Figure 4-5 As shown, the nozzle 6 is provided with a cleaning port 7 located on one side of the laparoscope lens 24. The gas delivery direction of the cleaning port 7 is perpendicular to the mirror surface of the laparoscope lens 24. The cleaning port 7 is located on the side of the laparoscope lens 24 near the edge of the laparoscope cannula 1. Gas is ejected from the cleaning port 7 to blow and clean the laparoscope lens 24. After the gas is ejected, the air pressure flows along the inclined surface of the laparoscope lens 24, and the high flow rate of the gas completes the cleaning of the dirty parts of the laparoscope lens 24.

[0052] Example 2

[0053] The laparoscopic cannula 1 is a hollow cylinder; the first installation channel 4 and the second installation channel 3 are both tubular structures; a second fixing gasket 5 is fixedly installed inside the laparoscopic cannula 1, and the second fixing gasket 5 is made of soft polymer material; the second fixing gasket 5 has through holes for the first installation channel 4 and the second installation channel 3 to pass through, and the through holes are interference-fitted with the first installation channel 4 and the second installation channel 3 to ensure good sealing between the laparoscopic cannula 1 and the first installation channel 4 and the second installation channel 3; multiple second fixing gaskets 5 are provided inside the laparoscopic cannula 1 along the axial direction of the laparoscopic cannula 1, and the first installation channel 4 and the second installation channel 3 are fixed by the second fixing gaskets 5 to prevent relative sliding between the three; the rest is the same as in Embodiment 1.

[0054] Example 3

[0055] The laparoscopic cannula 1 is a cylindrical structure; the first installation channel 4 and the second installation channel 3 are both channel structures opened inside the laparoscopic cannula 1, and the rest are the same as in Embodiment 1.

[0056] Example 4

[0057] The laparoscopic cannula 1 is made of soft polymer material. To facilitate the insertion of the laparoscope 16 into the first installation channel 4, the first installation channel 4 has a first notch, the direction of which is the same as the axial direction of the first installation channel 4, and the length of the first notch is equal to the length of the first installation channel 4. An elastic gasket is fixedly installed inside the first installation channel 4, and the elastic gasket has a second notch corresponding to the first notch. Multiple elastic gaskets are provided inside the first installation channel 4 along its axial direction. The rest is the same as in Embodiment 1. The outer peripheral surface of the laparoscopic cannula 1, except at the position of the first notch, is a regular and smooth cylindrical surface. The outer surface of the laparoscope 16 is exposed at the position of the first notch, and the outer surface of the laparoscope 16 is also a regular and smooth cylindrical surface. Therefore, the abdominal trocar 15 can still be sealed and fitted with the outer peripheral surface of the laparoscopic cannula 1 and the outer surface of the laparoscope 16 exposed from the first notch.

[0058] Example 5

[0059] The difference from Embodiment 1 is that the nozzle 6 is replaced with a flat nozzle 17. The flat nozzle 17 is provided with a flat cleaning port 18 located on one side of the laparoscope lens 24. The gas delivery direction of the flat cleaning port 18 is perpendicular to the mirror surface of the laparoscope lens 24. The flat cleaning port 18 is located on the side of the laparoscope lens 24 near the edge of the laparoscope cannula 1. Gas is ejected from the flat cleaning port 18 to clean the laparoscope lens 24. After the gas is ejected, the air pressure flows along the inclined surface of the laparoscope lens 24. The high flow rate of the gas completes the cleaning of the dirty parts of the laparoscope lens 24. The gas blown out from the flat cleaning port 18 has a larger range and can clean the dirt on the laparoscope lens 24 more quickly.

[0060] Example 6

[0061] like Figure 10-12 As shown, the abdominal surgical instrument is a laparoscope 16; the laparoscope 16 is equipped with a ventilation tube; a first tracheal interface is provided on the laparoscope 16 at the position corresponding to the air inlet of the ventilation tube; the first tracheal interface is connected to the air source through the tracheal tube 14; the axial direction of the air outlet of the ventilation tube is parallel to the laparoscope lens 24.

[0062] The tracheal tube 14, the air source, and the device between the tracheal tube 14 and the air source are the same as in Example 1.

[0063] As a specific implementation of this embodiment, the first tracheal interface is a snap-fit ​​structure, through which the tracheal tube 14 is snapped and fixed; the snap-fit ​​structure is existing technology and will not be described in detail here.

[0064] Furthermore, the laparoscope 16 is provided with an air guide groove 23 on the outer side of the laparoscope lens 24; the air guide groove 23 is provided with a first air outlet pipe 21 parallel to the laparoscope lens 24; the laparoscope 16 is provided with a first air inlet pipe 22 communicating with the first air outlet pipe 21; the first air outlet pipe 21 and the first air inlet pipe 22 form a ventilation pipe; a first tracheal interface is provided at the air inlet position of the first air inlet pipe corresponding to the first air inlet pipe 22 on the laparoscope 16.

[0065] As a specific implementation of this embodiment, one end face of the air guide groove 23 is fitted with the laparoscope lens 24, and the air guide groove 23 is provided with a groove; the groove is recessed from the end face fitted with the laparoscope lens 24 in a direction away from the laparoscope lens 24; the groove and the laparoscope lens 24 form a first air outlet channel 21.

[0066] When the laparoscopic lens 24 is dirty, stepping on the flushing foot switch 10 will cause gas to be ejected from the first vent pipe 21, thus cleaning the lens.

[0067] Example 7

[0068] like Figure 8-9 As shown, the abdominal surgical instrument is an irrigation and suction device 19; the irrigation and suction device 19 is equipped with a ventilation pipe; the irrigation and suction device 19 is equipped with a switch regulating valve; the switch regulating valve controls the opening and closing of the ventilation pipe; the irrigation and suction device 19 is equipped with a second tracheal interface at the air inlet position corresponding to the ventilation pipe; the second tracheal interface is connected to the air source through the tracheal pipe 14.

[0069] The tracheal tube 14, the air source, and the device between the tracheal tube 14 and the air source are the same as in Example 1.

[0070] As a specific implementation of this embodiment, the second tracheal interface is a snap-fit ​​structure, through which the tracheal tube 14 is snapped and fixed; the snap-fit ​​structure is existing technology and will not be described in detail here.

[0071] Furthermore, the ventilation duct includes a second air inlet duct and a second air outlet duct; one end of the second air inlet duct is connected to the second air pipe interface, and the other end is connected to the second air outlet duct; the second air outlet duct is the internal flushing channel 20 of the flushing suction device 19.

[0072] As a specific embodiment of this example, the handle housing of the flushing suction device 19 is provided with a switch regulating valve and a controller; the controller is electrically connected to the switch regulating valve and the pressure stabilizing control device 9; a trigger for operating the controller is installed on the handle housing; when the trigger is pressed, gas flows out from the second gas outlet pipe.

[0073] The switching control valve and the trigger for controlling the opening and closing of the switching control valve are existing technologies and will not be described in detail here.

[0074] The irrigation suction device 19 is inserted into the surgical site through the abdominal trocar 15. When the laparoscope lens 24 is dirty, the position and angle of the irrigation suction device 19 are manually adjusted so that the internal irrigation channel 20 of the irrigation suction device 19 is aligned with the area to be cleaned. Then, the trigger is pressed to open the switch regulating valve on the irrigation suction device 19 to clean the lens.

[0075] Example 8

[0076] like Figure 13-14 As shown, the abdominal surgical instrument is an abdominal trocar 15; the abdominal trocar 15 is equipped with a ventilation channel; the ventilation channel includes a third air inlet channel 25 and a third air outlet channel 26; one end of the third air inlet channel 25 is connected to a gas source, and the other end is connected to a gas flushing area 28; one end of the third air inlet channel 25 is connected to the gas flushing area 28, and the other end is connected to a negative pressure device; a one-way sealing valve 27 is installed inside the puncture cannula of the abdominal trocar; the one-way sealing valve 27 is located between the comprehensive sealing valve of the abdominal trocar 15 and the outlet of the puncture cannula; there is a vertical positional difference between the outlet of the third air inlet channel 25 and the inlet of the third air outlet channel 26; the puncture cannula area between the outlet of the third air inlet channel 25 and the inlet of the third air outlet channel 26 is the gas flushing area 28.

[0078] The third tracheal interface is a snap-fit ​​structure, which secures the trachea in place. This snap-fit ​​structure is existing technology and will not be described in detail here.

[0079] The tracheal tube 14, the air source, and the device between the tracheal tube 14 and the air source are the same as in Example 1.

[0080] Furthermore, the outlet of the third air inlet pipe 25 is lower than the inlet of the third air outlet pipe 26 to ensure that the gas cleans the laparoscope via an upward path.
