Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a single micro-hole assisted thoracoscope for lobectomy and a method of using the same. Background Art

[0002] Thoracoscopic surgery is a minimally invasive surgical method that has been widely used in the field of thoracic surgery in recent years. It completes the surgical operation by creating one or more small incisions in the patient's chest and inserting a thoracoscope and other surgical instruments. Compared with traditional open chest surgery, thoracoscopic surgery has the advantages of less trauma, faster recovery, shorter hospitalization time and less pain. However, during complex operations such as lobectomy, bleeding or tissue fluid accumulation often occurs in the surgical area. These body fluids may stain the lens of the thoracoscope, affecting the clarity of the surgical field of view, and thus affecting the safety and efficiency of the operation. At present, in order to keep the field of view of the surgical area in the patient's body clear, doctors usually need to constantly remove the thoracoscope from the patient's body and then manually clean the dirt on the lens. This process not only increases the operation time, but also may cause additional infection risks. In addition, reinserting the thoracoscope also requires adjusting the field of view. For example, an automatic decontamination thoracoscope disclosed in publication number CN111728582A cleans the body fluid on the surface of the end cover by arranging a brush rod on the surface of the end cover and driving the brush rod to orbit around the axis of the inner pipe through a rotating shaft (the running trajectory of the brush rod can be referred to Figure 1 As shown), although the purpose of cleaning the body fluids on the surface of the end cover is achieved, the brush rod will always cover part of the surface of the end cover, thereby blocking the camera, resulting in an image blind spot during the operation. This image blind spot will reduce the doctor's field of view and is extremely unsafe for patients. Based on the above problems, this application document proposes a single microhole assisted thoracoscope for lobe surgery to improve the above problems. Summary of the invention

[0038] Please see attached Figures 2 to 6 as well as Fig.10 As shown, it is the first embodiment of the present invention, which provides a single micro-hole assisted thoracoscope for lung lobe surgery, including a thoracoscope body 10, one end of the thoracoscope body 10 is provided with an image acquisition end 11, the end of the thoracoscope body 10 away from the image acquisition end 11 is provided with a holding end, and a control component is provided on the holding end, and an end inside the image acquisition end 11 is equipped with a lighting element 12 and a plurality of camera elements 13, and the plurality of camera elements 13 are annularly arrayed on the outside of the lighting element 12, and the lighting element 12 and the control component, and the camera element 13 and the control component are electrically connected through wires, and a shell 14 and a protective cover 15 are fixed to one end outside the image acquisition end 11, and the protective cover 15 is located inside the shell 14, and a cleaning rod 16 is installed on the outside of the protective cover 15, and the cross-sectional shapes of the protective cover 15 and the cleaning rod 16 are both semicircular, and the protective cover 15 and the cleaning rod 16 are adapted to each other, and also include:

[0039] A cleaning unit 20, which is assembled between the image acquisition end 11 and the housing 14, and the cleaning unit 20 and the cleaning rod 16 as well as the cleaning unit 20 and the control assembly are connected;

[0040] The rotation axis of the cleaning rod 16 and the central axis of the shell 14 are perpendicular to each other. The cleaning portion 20 can drive the cleaning rod 16 to swing back and forth on the surface of the protective cover 15 . In the initial state, the cleaning rod 16 is located inside the shell 14 .

[0041] Here, the imaging element 13 is a medical cold light source to provide good light. The shell 14 can be made of any of the following materials: PTFE, PI, PEEK or other polymer materials. In the initial state, the end of the shell 14 close to the protective cover 15, the lighting element 12 and the cleaning rod 16 are all located in the same plane, and the cleaning rod 16 will not block the lighting element 12.

[0042] It should be noted that the device is also used in conjunction with a mirror sheath, and the image acquisition end 11 can enter the patient's body through the mirror sheath to obtain images inside the patient's body.

When blood or other body fluids adhere to the surface of the protective cover 15, causing the image acquisition to be blurred, the cleaning part 20 is started through the control component. Since the cleaning part 20 is connected to the cleaning rod 16, the cleaning rod 16 is driven by the cleaning part 20. 16 operates, so that the cleaning rod 16 swings back and forth on the surface of the protective cover 15, and the body fluids adhered to the surface of the protective cover 15 are cleaned by the cleaning rod 16 to ensure that the lighting element 12 can stably collect images of the patient's body, so that the device does not need to be taken out of the patient's body to clean the body fluids on the surface of the protective cover 15, thereby reducing the risk of surgical infection. After cleaning, the cleaning part 20 drives the cleaning rod 16 to reset, so that the cleaning rod 16 rotates to the inside of the shell 14, thereby avoiding the cleaning rod 16 from blocking the lighting element 12 and forming an image blind area.

[0044] Next, please refer to Figures 5 to 7 As shown, the cleaning unit 20 includes a hollow shaft motor 21, an incomplete crown gear 22, a first driven gear 23 and a second driven gear 24. The hollow shaft motor 21 is assembled between the image acquisition end 11 and the shell 14, and the hollow shaft motor 21 and the control component are electrically connected through a wire. The incomplete crown gear 22 is fixed to the output end of the image acquisition end 11, the first driven gear 23 and the second driven gear 24 are fixed to both sides of the outer side of the shell 14, and the incomplete crown gear 22 and the first driven gear 23 and the incomplete The full crown gear 22 and the second driven gear 24 are meshedly connected, wherein the first driven gear 23 and the second driven gear 24 are alternately meshedly connected with the incomplete crown gear 22 (that is, the first driven gear 23 and the second driven gear 24 cannot be meshedly connected with the incomplete crown gear 22 at the same time). When the incomplete crown gear 22 and the first driven gear 23 are meshedly connected, the cleaning rod 16 rotates forward, and when the incomplete crown gear 22 and the second driven gear 24 are meshedly connected, the cleaning rod 16 rotates reversely.

[0045] Here, the forward rotation and the reverse rotation are only used to express that the rotation direction of the cleaning rod 16 has changed, and do not constitute a specific limitation.

[0046] It should be noted that the hollow shaft motor 21 at least includes a shell, a stator, a hollow shaft rotor and multiple sealing elements. The shell is fixed to the inside of the shell 14, the stator is fixed to the inside of the shell, a winding is arranged on the stator, the hollow shaft is assembled inside the rotor, and multiple sealing elements are arranged between the shell and the hollow shaft rotor. In the present embodiment, the hollow shaft rotor is sleeved on one end of the outer side of the image acquisition end 11 close to the protective cover 15, the hollow shaft rotor and the image acquisition end 11 are clearance-fitted, and the hollow shaft rotor and the incomplete crown gear 22 are fixedly connected. Specifically, the hollow shaft motor 21 is an existing mature application. In the present embodiment, the hollow shaft motor 21 is preferably a brushless hollow shaft motor of the brand Cang Xingda, and the specific model is adjusted according to relevant size requirements.

[0047] In this embodiment, the hollow shaft motor 21 is started, and the incomplete crown gear 22 is rotated by the output end of the hollow shaft motor 21 through the fixed connection between the hollow shaft motor 21 and the incomplete crown gear 22. Since the first driven gear 23 and the second driven gear 24 are alternately meshed with the incomplete crown gear 22, when the incomplete crown gear 22 and the first driven gear 23 are meshed, the cleaning rod 16 rotates forward, and when the incomplete crown gear 22 and the second driven gear 24 are meshed, the cleaning rod 16 rotates reversely. Through the cooperation of the incomplete crown gear 22, the first driven gear 23 and the second driven gear 24, the cleaning rod 16 rotates forward and reversely alternately, so that the cleaning rod 16 swings back and forth on the surface of the protective cover 15, and the body fluids adhered to the surface of the protective cover 15 are cleaned by the cleaning rod 16 to ensure the clarity of the image captured by the lighting element 12.

[0048] Secondly, please also refer to Figure 8 and Fig. 9 A plurality of driving tooth segments 25 in an annular array are evenly arranged on the upper end of the incomplete crown gear 22 , and the incomplete crown gear 22 and the first driven gear 23 as well as the incomplete crown gear 22 and the second driven gear 24 are meshedly connected through the driving tooth segments 25 .

[0049] It should be noted that the central angles between any two adjacent driving tooth segments 25 are the same. When the first driven gear 23 is meshed and connected with any driving tooth segment 25, the second driven gear 24 does not contact with any driving tooth segment 25. When the second driven gear 24 is meshed and connected with any driving tooth segment 25, the first driven gear 23 does not contact with any driving tooth segment 25.

[0050] In this embodiment, a plurality of annular arrays of driving tooth segments 25 are provided so that the first driven gear 23 and the second driven gear 24 can be alternately meshed and connected with the driving tooth segments 25, and then the first driven gear 23 and the second driven gear 24 are driven to rotate alternately through the cooperation of the plurality of driving tooth segments 25, and the cleaning rod 16 is driven to rotate forward and reverse alternately through the cooperation of the first driven gear 23 and the second driven gear 24.

[0051] In a specific embodiment, the number of driving tooth segments 25 is 9, and the center angle between two adjacent driving tooth segments 25 is 40°. Of course, the number of driving tooth segments 25 and the center angle between two adjacent driving tooth segments 25 can be adjusted according to actual design requirements and usage requirements, and no specific limitation is constituted herein.

[0052] Next, please refer to Figure 7 and Fig. 9 As shown, an elastic cleaning element 17 is fixed to the inner wall of the cleaning rod 16 , and the inner wall of the elastic cleaning element 17 is in contact with the outer wall of the protective cover 15 .

[0053] In this embodiment, the cross-sectional shape of the cleaning rod 16 may change due to factors such as the usage environment, usage duration, and the material's own characteristics. After the cleaning rod 16 is deformed, the elastic cleaning element 17 with elastic properties can always fit the outer wall of the protective cover 15 to ensure the cleaning effect of the outer wall of the protective cover 15.

[0054] In a preferred embodiment, the material of the protective cover 15 can be any one of the following materials: polycarbonate, cycloolefin copolymer, MED6 thoracoscope body 10 or other transparent materials with biocompatible properties. In this embodiment, the material of the protective cover 15 is preferably MED6 thoracoscope body 10.

[0055] In this embodiment, through the above-mentioned arrangement, the protective cover 15 provides protection for the image acquisition end 11 and the lighting element 12, while also enabling the protective cover 15 to maintain a high light transmittance, thereby ensuring the clarity of the image acquisition of the lighting element 12. At the same time, during the operation, the protective cover 15 may come into contact with the patient's internal tissues. The biocompatible material will not cause an overreaction of the immune system when in contact with human tissues, which helps to reduce inflammation, allergic reactions and other adverse physiological reactions, thereby improving the safety and comfort of the patient.

[0056] In a preferred embodiment, the material of the elastic cleaning element 17 can be any one of the following materials: polydimethylsiloxane, polyvinyl alcohol, polyester or other non-metallic materials with biocompatibility and good elasticity. In this embodiment, the material of the elastic cleaning element 17 is preferably polydimethylsiloxane.

[0057] It should be noted that, in the present embodiment, the elastic cleaning element 17 is in the shape of a strip, and its cross-sectional shape may be any one of the following shapes: rectangle, square, triangle, trapezoid, arc.

[0058] In this embodiment, through the above-mentioned arrangement, after the cleaning rod 16 is deformed due to factors such as the use environment, the duration of use and the material's own characteristics, the elastic cleaning element 17 of the elastic material can always fit the surface of the protective cover 15 to ensure the cleaning effect.

[0059] Please refer again Figure 3 A plurality of drainage grooves 18 are evenly formed on one end of the outer side of the shell 14 close to the protective cover 15 , and the plurality of drainage grooves 18 are located at one end of the hollow shaft motor 21 .

[0060] In this embodiment, due to components such as the cleaning rod 16, the first driven gear 23 and the second driven gear 24, the shell 14 cannot be made into a closed chamber. During the operation, body fluids will enter the shell 14 and adhere to the inner wall of the shell 14. The setting of the drainage groove 18 can clean the inner wall of the shell 14. After cleaning, the cleaning liquid and body fluids can flow out of the shell 14 through the drainage groove 18.

[0061] It should be noted that, in this embodiment, when the device is cleaned and disinfected, the shell 14 can be soaked or rinsed with medical disinfectant alcohol, and then disinfected and sterilized by ultraviolet irradiation.

[0065] Step 2: When body fluids adhere to the surface of the protective cover 15, the hollow shaft motor 21 is started to rotate the incomplete crown gear 22, and the cleaning rod 16 is driven to swing back and forth on the surface of the protective cover 15 through the cooperation of the incomplete crown gear 22, the first driven gear 23 and the second driven gear 24, so that the body fluids adhered to the surface of the protective cover 15 are cleaned by the cleaning rod 16;

[0066] Step 3: After cleaning, the cleaning rod 16 is driven by the hollow shaft motor 21 to rotate to the inside of the shell 14 for reset, and the hollow shaft motor 21 is turned off to prevent the cleaning rod 16 from blocking the lighting element 12.
