Description

Technical Field

[0001] This application relates to the technical field of medical supplies, and particularly to a laparoscopic lens decontamination device. Background Art

[0002] Laparoscopic surgery has become the standard surgery for treating abdominal and pelvic diseases. The most crucial technology in laparoscopic surgery is the laparoscope. As the soul of laparoscopic technology, once the vision or clarity of the laparoscope is affected during the operation, the surgeon has to stop the operation in time to clean the lens so that the lens can regain clarity and vision. Generally, in a simple laparoscopic surgery, the surgeon has to pause the operation at least 3 times due to unclear lens. In the case of a large laparoscopic surgery, the number of times of pausing the operation will increase exponentially.

[0003] To solve the problem of unclear lens, doctors and enterprises have tried various methods. For example, doctors will insert the laparoscope into a thermos cup, wipe antifog oil, etc., so that the endoscope can maintain clarity for a long time. However, these little tricks cannot really solve the problem. During the operation, doctors still have to pause the operation from time to time, take out the endoscope from the abdominal cavity or thoracic cavity, and perform decontamination outside the body (such as defogging, blood stains, oil stains, tissue fragments, etc.).

When the combination of technical solutions results in contradictions or inability to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0022] Referring to the attached Figures 1 to 8 As shown, the embodiment of the present application provides a laparoscopic lens decontamination device, including a sheath tube 1, a cleaning mechanism 3, and a handle 2. The sheath tube 1 is connected to the handle 2. The sheath tube 1 is axially provided with a channel for the laparoscopic lens 9 to pass through during the operation. The cleaning mechanism 3 is arranged at the distal end of the sheath tube 1 for cleaning and decontaminating the blurred laparoscopic lens 9 during the operation. The handle 2 is provided with a cleaning mechanism adjustment component 4 and a cleaning sponge adjustment component 5. The cleaning mechanism adjustment component 4 is used to adjust the forward and backward movement of the cleaning mechanism 3 relative to the sheath tube 1 and to rotate the cleaning mechanism 3. The cleaning sponge adjustment component 5 is used to rotate the cleaning sponge 303.

[0023] It can be found that during laparoscopic surgery, a surgical channel is formed using a laparoscopic trocar, the sheath tube 1 is placed into the surgical channel, and then the laparoscopic lens 9 is inserted through the sheath tube 1 into the abdominal cavity. The cleaning mechanism 3 is moved by the cleaning mechanism adjustment component 4 to be attached to the laparoscopic lens 9 and the cleaning mechanism 3 is rotated to clean and decontaminate the lens. And since the laparoscopic lens 9 needs to be cleaned multiple times during the operation, the cleaning sponge 303 is rotated by the cleaning sponge adjustment component 5 so that each time it can contact the laparoscopic lens 9 with a clean cleaning surface, ensuring the cleanliness of the cleaning.

[0024] Specifically: As Figures 1 to 3As shown in the figure, the cleaning mechanism 3 includes a cleaning frame 301, a cleaning sponge 303, and a sleeve 401. The cleaning frame 301 is designed with an open side facing the laparoscope lens 9 and a closed design on the other sides. The cleaning sponge 303 is rotatably mounted on the cleaning frame 301 through a shaft rod 302 and partially protrudes from the cleaning frame 301 to be able to brush the laparoscope lens 9. One end of the sleeve 401 is connected to the cleaning mechanism adjustment assembly 4. The sleeve 401 extends along the outer wall of the sheath tube 1 to the distal end of the sheath tube 1, and the other end of the sleeve 401 is bent at the distal end of the sheath tube 1 and fixedly connected to the cleaning mechanism 3. Thus, by operating the sleeve 401 through the cleaning mechanism adjustment assembly 4, the movement and rotation of the cleaning mechanism 3 can be achieved.

[0025] In one embodiment, as Figure 1 shown, a lateral channel 8 is provided along the outer wall of the sheath tube 1. The lateral channel 8 extends from the handle 2 all the way to the cleaning mechanism adjustment assembly 4. The sleeve 401 extends along the lateral channel 8 to be connected to the cleaning mechanism adjustment assembly 4.

[0026] In the above, as Figure 4 shown, the cleaning sponge 303 is a cylindrical structure and at least four inclined cutting surfaces 304 are cut out. Since the laparoscope lens 9 has a certain inclination, the purpose of designing the inclined cutting surfaces 304 is to better contact the laparoscope lens 9. The design of the four inclined cutting surfaces 304 is to be able to rotate the cleaning sponge 303 during the operation to replace the inclined cutting surfaces 304 in contact with the laparoscope lens 9. During the laparoscopic surgery process, the laparoscope lens 9 may have fog, blood stains, oil stains, and tissue debris. And during a simple operation, the cleaning times of the laparoscope lens 9 can reach at least three times. If the same cleaning surface is always in contact with the laparoscope lens 9 throughout the entire operation process, then inevitably during the subsequent decontamination process, the soiled cleaning surface cannot achieve an effective cleaning effect and may even become dirtier with wiping. Therefore, by rotating the cleaning sponge 303, a new clean surface can be replaced for brushing and decontamination, and the cleaning effect is better.

[0027] To achieve the adjustment effect of the cleaning mechanism 3, as Figure 7 and Figure 8As shown, the cleaning mechanism adjustment assembly 4 includes a slider 402 and a first adjustment knob 403. The slider 402 is used to drag the sleeve 401 to move the cleaning mechanism 3 back and forth, and the first adjustment knob 403 is used to turn the sleeve 401 to rotate the cleaning mechanism 3. Specifically, the handle 2 is provided with a guiding chute 404 in the front-back direction. The slider 402 is slidably arranged in the guiding chute 404. To limit the movement of the slider 402, a lateral groove 405 is provided on the side of the guiding chute 404. A flange 406 is formed on the side of the slider 402 and protrudes into the lateral groove 405. At the same time, an installation through-hole is provided in the middle of the slider 402, and the first adjustment knob 403 is rotatably arranged in the installation through-hole. Both the slider 402 and the first adjustment knob 403 communicate with the lateral hole passage 8. The sleeve 401 extends into the interior of the first adjustment knob 403 and maintains an interference fit with the first adjustment knob 403. Thus, it can be imagined that when the slider 402 is moved back and forth, since the first adjustment knob 403 is located within the slider 402, as the slider 402 moves back and forth, the first adjustment knob 403 moves back and forth synchronously. And the sleeve 401 is fixedly connected to the first adjustment knob 403, and the distal end of the sleeve 401 is fixed with the cleaning mechanism 3. Thus, the back-and-forth movement of the cleaning mechanism 3 can be driven by the back-and-forth movement of the slider 402, and the rotation of the cleaning mechanism 3 can be achieved by turning the first adjustment knob 403 to twist the sleeve 401.

[0028] In a preferred embodiment, in order to limit the position of the cleaning mechanism 3 during the operation, as Figure 8 and Figure 9 shown, elastic locking mechanisms 6 for positioning the position of the slider 402 are provided at both ends of the guiding chute 404. Among them, the elastic locking mechanism 6 includes a first ball-headed rod 601 and a first spring 602. A first side groove is provided laterally on the guiding chute 404. The first spring 602 is fixed in the first side groove, and the first spring 602 is sleeved on the first ball-headed rod 601. Annular grooves 407 are provided on the front and back side walls of the slider 402. The first spring 602 pushes the first ball-headed rod 601 into the annular groove 407 to apply a resistance to the slider 402 so that the self-movement of the slider 402 can be restricted. At the same time, a number of tooth grooves are provided in the installation through-hole, and a number of convex teeth are provided on the first adjustment knob 403. The convex teeth are in an engaged state with the tooth grooves, and the damping fit is achieved by using the fact that the material can be deformed to a certain extent when being extruded, so as to prevent the first adjustment knob 403 from rotating autonomously without external force.

[0029] At the same time, in this embodiment, to achieve the adjustment effect on the cleaning sponge 303, as Figures 2 to 9As shown in the figure, the cleaning sponge adjusting assembly 5 includes a gear 506, a square guide bar 502, and a second adjusting knob 501. The gear 506 is fixedly arranged on the shaft rod 302, and the gear 506 is located inside the sleeve 401. The sleeve 401 is provided with a square channel. The square guide bar 502 is arranged inside the sleeve 401 and extends along the sleeve 401 and is restricted from rotating by the square channel. The square guide bar 502 is bent at one end of the gear 506 by 90 degrees and is set as a rack portion 503. The rack portion 503 meshes with the gear 506. The second adjusting knob 501 is rotationally connected to the slider 402 with damping and is rotationally connected to the handle 2 without damping. The square guide bar 502 is provided with a threaded rod portion 504 at one end of the second adjusting knob 501. The second adjusting knob 501 is provided with a threaded deep hole 507 along the axial direction. The threaded rod portion 504 is in fit connection with the threaded deep hole 507. Thus, it can be imagined that when it is necessary to rotate the cleaning sponge 303, just hold the first adjusting knob 403 with one hand without rotating, and rotate the second adjusting knob 501 with the other hand. Since the square guide bar 502 cannot rotate, under the cooperation of the threaded rod portion 504 and the threaded deep hole 507, the square guide bar 502 can only move back and forth. During the process of the square guide bar 502 moving back and forth, the rack portion 503 meshes with the gear 506, thereby driving the shaft rod 302 to rotate, and the rotation of the shaft rod 302 realizes the rotation of the cleaning sponge 303.

[0030] In a preferred embodiment, in order to achieve the damping rotational connection between the second adjusting knob 501 and the slider 402 and the non-damping rotational connection with the handle 2, it should be noted that the non-damping rotational connection here is an extreme statement, and actually it is a small-damping rotation. As Figure 8 and Figure 9 shown, the second adjusting knob 501 is provided with a T-shaped head at one end of the slider 402. The slider 402 is provided with a T-shaped groove at one end of the second adjusting knob 501. The T-shaped head is assembled and connected with the T-shaped groove. The slider 402 is provided with a damping member 7 for pressing against the T-shaped head outside the T-shaped groove. Among them, the damping member 7 includes a second spherical head ejector rod 701 and a second spring 702. The T-shaped groove is provided with a second side groove on the side. The second spring 702 is fixed in the second side groove. The second spherical head ejector rod 701 is arranged in the second side groove, and the second spring 702 is fixedly connected with the second spherical head ejector rod 701. The second spring 702 is used to press the second spherical head ejector rod 701 against the T-shaped head to form a resistance to the rotation of the second adjusting knob 501. Of course, a spherical surface groove 505 for cooperating with the second spherical head ejector rod 701 is provided on the T-shaped head. There are multiple spherical surface grooves 505, and the number is the same as the number of inclined sections 304 of the cleaning sponge 303. The spherical surface grooves 505 are arranged in a circumferential array along the T-shaped head. At the same time, a light hole is provided at the tail of the handle 2. The second adjusting knob 501 is rotatably arranged in the light hole to form a small-damping rotation.

[0031] It can be understood that when it is necessary to rotate the cleaning mechanism 3 through the first adjustment knob 403, since the second adjustment knob 501 is rotationally connected to the slider 402 with damping and is rotationally connected to the handle 2 without damping, the rotation of the first adjustment knob 403 will cause the second adjustment knob 501 to rotate synchronously, without causing the front-back movement of the square guide bar 502. By holding the first adjustment knob 403 and rotating the second adjustment knob 501, the front-back movement of the square guide bar 502 can be realized to rotate the cleaning sponge 303, and the damper 7 can prevent the second adjustment knob 501 from rotating autonomously without external force.

[0032] Of course, in the above, for the convenience of replacing the cleaning sponge 303 after the operation, as Figure 3 shown, the end of the sleeve 401 is provided with an external thread, and the outer wall of the cleaning frame 301 is provided with a threaded sleeve. The sleeve 401 is threadedly connected to the threaded sleeve. The shaft rod 302 and the cleaning frame 301 are movably matched. By screwing the cleaning frame 301 off the sleeve 401 and removing the cleaning sponge 303 together with the cleaning frame 301 from the shaft rod 302, a new cleaning sponge 303 can be replaced.

[0033] In summary, a laparoscopic lens decontamination device provided by an embodiment of the present application has the following usage method: First, use a laparoscopic trocar to establish a surgical channel; Then insert the sheath 1 into the working channel of the laparoscopic trocar, and then insert the laparoscopic lens 9 into the abdominal cavity through the sheath 1. It should be noted that in the initial state, the cleaning mechanism 3 is in a state of being away from the distal end of the sheath 1 and facing the distal end surface of the sheath 1, so as to facilitate passing through the working channel (as Figure 10 shown); Then, under laparoscopy, rotate the first adjustment knob 403 to rotate the cleaning mechanism 3 by 180 degrees to the outside of the sheath 1, and drive the cleaning mechanism 3 to move backward by sliding the slider 402 backward to avoid the laparoscopic lens 9 and prevent blocking the surgical field (as Figure 11 shown). Of course, it can be understood that in order to accurately master the rotation angle of the first adjustment knob 403, as Figure 7 shown, an arrow mark is set at the center position of the surface of the slider 402, and four scale lines are arranged in a circle around the outer peripheral wall of the first adjustment knob 403 to equally divide the circumference. Thus, by rotating the arrow mark to align with the scale line, the rotation angle of the first adjustment knob 403 can be mastered; When the field of view of the laparoscopic lens 9 becomes blurred and the lens needs to be cleaned; First, slide the slider 402 forward to the front end, then turn the first adjustment knob 403 to drive the sleeve 401 to rotate, and the sleeve 401 drives the cleaning mechanism 3 to rotate, and use the cleaning sponge 303 to fit the laparoscope lens 9 for cleaning and decontamination. After cleaning, move the cleaning mechanism 3 backward according to the above steps again to avoid the laparoscope lens 9; When the laparoscope lens 9 needs to be cleaned and decontaminated again, the square guide bar 502 is driven to move by rotating the second adjusting knob 501, and the cleaning sponge 303 is rotated by the meshing of the rack portion 503 and the gear 506. Since the second adjusting knob 501 forms a damped rotation between the damping member 7 and the slider 402, when the second ball head top rod 701 rotates a certain angle, it will bounce into the spherical groove 505, and a "ticking" sound can be heard, and the resistance will also be different. This can be used to judge whether the cleaning sponge 303 has switched to a new cleaning surface, and then the laparoscope lens 9 is cleaned and decontaminated through the aforementioned steps.

[0034] In summary, a laparoscopic lens decontamination device provided in an embodiment of the present application, by providing a sheath 1, a cleaning mechanism 3, a cleaning mechanism adjustment component 4 and a cleaning sponge adjustment component 5, when performing laparoscopic surgery, the sheath 1 is passed through the laparoscopic puncture device, and the laparoscope lens 9 passes through the sheath 1, and the cleaning mechanism adjustment component 4 is used to adjust the cleaning mechanism 3 to be close to the laparoscope lens 9 and rotate the cleaning mechanism 3 to clean and decontaminate the laparoscope lens 9, which can minimize the disadvantage of repeatedly taking the laparoscope out of the body for decontamination during the operation, and because the cleaning sponge adjustment component 5 is provided, the cleaning sponge 303 can be rotated, so that the cleaning sponge 303 can be switched during the operation so that the clean cleaning surface is in contact with the laparoscope lens 9, ensuring that there is always a clean cleaning surface for decontamination when the laparoscope lens 9 is cleaned multiple times during the operation, and effectively ensuring the decontamination effect.

[0035] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
