Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a laparoscope device that is easy to clean. Background Art

[0002] Laparoscope is a very important medical device, which is often used in abdominal surgery, so that medical personnel can intuitively see the lesions in the patient's body. The main working principle of the laparoscope is that a camera and a lighting device are built into the front end of the probe rod, so as to display the situation inside the patient's body on an external display screen. However, during routine use, due to the low temperature of the glass cover at the front end of the camera, a layer of fog will be generated after entering the patient's body, thereby affecting the camera's shooting clarity. At the same time, the body fluids, fat and other tissues inside the patient's abdominal cavity will also be stained on the surface of the glass cover, further causing the shooting clarity to decrease, making it impossible for medical personnel to clearly observe the lesions. The lens needs to be removed and wiped, which wastes time.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

The operator controls the operation of the device in the shell 1 through the control device 2.

[0035] Please refer to Figure 1-Figure 4An upper protrusion 3 is provided on the top of the shell 1, a front stroke hole 4 is opened on the inner wall of the shell 1 near the front end, a rear stroke hole 5 is opened on the inner wall of the shell 1 at a position behind the front stroke hole 4, an upper guide hole 6 is opened on the top of the inner wall of the shell 1 near the front end, the upper guide hole 6 runs through the interior of the upper protrusion 3 and extends to the top of the inner wall of the rear stroke hole 5, a storage tank 7 is provided on the top of the junction of the inner walls of the front stroke hole 4 and the rear stroke hole 5, a spiral guide groove 8 is opened on the inner wall of the rear stroke hole 5 near the front end, the number of the spiral guide grooves 8 is two and they are distributed in a mirror-symmetrical manner, a stroke device 9 is provided on the internal movable sleeve of the rear stroke hole 5, and when the stroke device 9 moves, the squeezed air will be guided through the upper guide hole 6.

[0036] Please refer to Figure 1-Figure 4 A camera device 10 is movably installed inside the stroke device 9, and a negative pressure device 11 is fixedly installed at the end of the camera device 10. A lower protrusion 12 is provided at the bottom of the outer surface of the shell 1, and a lower guide hole 13 is opened at the bottom of the inner wall of the shell 1 near the end of the spiral guide groove 8. The lower guide hole 13 passes through the interior of the lower protrusion 12 and extends to the inner cavity of the rear stroke hole 5. A driving device 14 is fixedly installed on the inner wall of the rear stroke hole 5 near the end.

[0037] Please refer to Figure 1-Figure 4 The spiral guide groove 8 has a spiral shape, and the spiral angle is one hundred and eighty degrees. The spiral guide groove 8 cooperates with the stroke device 9.

[0038] When the negative pressure device 11, the camera device 10 and the stroke device 9 are displaced backward synchronously, negative pressure will be formed in the space in the inner cavity of the front stroke hole 4 located at the front end of the camera device 10. At this time, the gas located at the rear side of the stroke device 9 will enter the negative pressure area inside the front stroke hole 4 through the upper guide hole 6 under the action of squeezing, thereby stabilizing the air pressure area inside the front stroke hole 4, avoiding part of the body fluids from being adsorbed into the interior of the front stroke hole 4, so that the camera device 10 is contaminated with these body fluids during the resetting process, resulting in a decrease in the cleaning effect. At the same time, it also avoids the situation where the negative pressure area of ​​the inner cavity of the front stroke hole 4 even adheres to the patient's internal tissues and causes discomfort to the patient, thereby improving the reliability of the device.

[0039] Please refer to Figure 5-Figure 6 The stroke device 9 includes a stroke sleeve 91, a T-shaped ring groove 92 is provided at the front end of the stroke sleeve 91, a cleaning device 93 is movably installed inside the T-shaped ring groove 92, there are two cleaning devices 93 and they are arranged in a mirror-symmetrical manner, and a conducting groove 94 is opened on the top of the outer surface of the stroke sleeve 91.

[0040] Please refer to Figure 3 and Figure 5-Figure 6A tailstock 95 is fixedly mounted at the end of the travel sleeve 91 , a travel spring 96 is disposed at the inner end of the tailstock 95 , and a front end of the travel spring 96 is connected to the end of the camera device 10 .

[0041] Please refer to Figure 4-Figure 6 The position of the conducting groove 94 corresponds to the top opening of the upper guide hole 6 at the front stroke hole 4, so as to avoid the upper guide hole 6 being blocked.

[0042] A storage tank 7 is provided at the top of the junction of the inner walls of the front stroke hole 4 and the rear stroke hole 5, so that the camera device 10 will extend from the interior of the front stroke hole 4 during the resetting process of the device. At this time, the cleaning device 93 rotates outward under the squeezing of the camera device 10, and is finally located inside the storage tank 7, avoiding the situation where the cleaning device 93 jams the camera device 10, thereby causing the camera device 10 to be unable to extend normally from the interior of the front stroke hole 4, thereby improving the reliability of the device.

[0043] Please refer to Figure 5-Figure 7 The cleaning device 93 includes a T-shaped slider 931 , which is movably installed inside the T-shaped ring groove 92 . The T-shaped slider 931 can rotate under the limiting effect of the T-shaped ring groove 92 .

[0044] Please refer to Figure 3 and Figure 6-Figure 7 The front end movable sleeve of the T-shaped slider 931 is provided with a rotating seat 932, and the front end of the rotating seat 932 is fixedly installed with an arc frame 933. The outer side of the arc frame 933 is provided with a liquid collecting tank 934. The inner circular surface of the arc frame 933 is in contact with the front end of the camera device 10. During the overall rotation of the cleaning device 93, the arc frame 933 will scrape the front end of the camera device 10, and the liquid collected by the scraping will be concentrated inside the liquid collecting tank 934.

[0045] Please refer to Figure 7 A contact rod 935 is fixedly installed on the top of the rotating seat 932, and a combined half pipe 936 is provided on the outer surface of the arc frame 933 near the rotating seat 932.

[0046] Please refer to Figure 3-Figure 4 and Figure 6-Figure 7 The contact rod 935 cooperates with the spiral guide groove 8. When the stroke device 9 moves as a whole, the contact rod 935 drives the cleaning device 93 to rotate along the axis of the stroke sleeve 91 as the rotation center under the limiting effect of the spiral guide groove 8.

[0047] When the housing 1 is inside the patient's body, due to the temperature difference between the camera device 10 and the patient's body, as well as the adhesion of body fluids in the patient's body, a liquid film will be formed on the front surface of the camera device 10, thereby affecting the shooting quality of the camera device 10. When the operator feels that he cannot see the specific situation inside the patient's body, he can operate the control device 2 to put the drive device 14 into operation. The drive device 14 will pull the negative pressure device 11, the camera device 10 and the stroke device 9 to move backward synchronously. In this process, since the contact rod 935 cooperates with the spiral guide groove 8, when the stroke device 9 moves as a whole, the contact rod 935 drives the cleaning device 93 along the limit of the spiral guide groove 8. The axis of the stroke sleeve 91 rotates as the center of rotation, and the spiral guide groove 8 has a spiral shape, and the spiral angle is one hundred and eighty degrees, so that the contact rod 935 drives the cleaning device 93 to rotate as a whole under the limiting action of the spiral guide groove 8. At this time, the inner circular surface of the arc frame 933 contacts the front end of the camera device 10, so that during the overall rotation of the cleaning device 93, the arc frame 933 will scrape the front end of the camera device 10, thereby achieving the cleaning effect on the front end of the camera device 10, avoiding the problem that a layer of liquid film is attached to the front end of the camera device 10, resulting in a decrease in shooting quality and the operator cannot clearly observe the lesion in the patient's body, thereby improving the practicality of the device.

[0048] Please refer to Figure 4 and Figure 6-Figure 7 After the cleaning device 93 rotates 180 degrees under the limiting effect of the spiral guide groove 8, the two combined half pipes 936 are combined into a pipeline and correspond to the front end of the lower guide hole 13.

[0049] Please refer to Figure 3 and Figure 8 The negative pressure device 11 includes a connecting seat 111, the front end of the connecting seat 111 is fixedly connected to the end of the camera device 10, and a front negative pressure plate 112 is fixedly installed at the end of the connecting seat 111. A round hole is opened on the front side of the front negative pressure plate 112 at a position outside the connecting seat 111, and a travel rod 113 is movably installed inside the round hole. A reset spring 114 is provided at the front end of the travel rod 113, and the end of the reset spring 114 is connected to the front side of the front negative pressure plate 112. A rear negative pressure plate 115 is fixedly installed at the end of the travel rod 113. After the camera device 10 reaches the stroke limit and stops moving, the connecting seat 111 also stops moving at the same time. At this time, the driving device 14 continues to pull the bar-shaped gear rod 116, which will separate the front negative pressure plate 112 and the rear negative pressure plate 115 and form a cavity between the two.

[0050] Please refer to Figure 3 and Figure 8A bar-shaped gear rod 116 is fixedly installed on the back side of the rear negative pressure plate 115 near the top. The bar-shaped gear rod 116 cooperates with the driving device 14, and the driving device 14 will pull the bar-shaped gear rod 116 to move when it is running.

[0051] Please refer to Figure 8 Sealing rings are provided on the outer sides of the front negative pressure plate 112 and the rear negative pressure plate 115 .

[0052] Please refer to Figure 3 and Figure 8 The front negative pressure plate 112 stops moving when it reaches the stroke limit, and the stop position is located at the front side of the opening of the inner wall of the rear stroke hole 5 at the end of the lower guide hole 13.

[0053] When both the stroke device 9 and the camera device 10 reach the stroke limit, the cleaning device 93 rotates one hundred and eighty degrees under the limiting action of the spiral guide groove 8, and the two combined half-tubes 936 are combined into a pipeline and correspond to the front end of the lower guide hole 13. At the same time, since the front end of the connecting seat 111 is connected to the camera device 10, the connecting seat 111 and the front negative pressure plate 112 are also in a stopped state. At this time, the driving device 14 continues to maintain the traction of the bar gear rod 116, which will separate the front negative pressure plate 112 and the rear negative pressure plate 115, thereby forming a cavity, and the interior of the cavity is in a negative pressure state. The negative pressure acts on the interior of the liquid collecting tank 934 through the lower guide hole 13 and the pipeline formed by the combined half-tube 936, thereby extracting the liquid concentrated in the liquid collecting tank 934, thereby keeping the interior of the liquid collecting tank 934 clean, avoiding the problem that the front end of the camera device 10 is contaminated with liquid during the overall resetting of the cleaning device 93, resulting in a decrease in the cleaning effect, thereby providing practicality of the device.

[0054] The method of use of the present invention is as follows:

[0055] During use, when the housing 1 is inside the patient's body, a liquid film will be formed on the front surface of the camera device 10 due to the temperature difference between the camera device 10 and the patient's body, as well as the adhesion of body fluids in the patient's body, thereby affecting the shooting quality of the camera device 10. When the operator feels that he cannot see the specific situation inside the patient's body, he can operate the control device 2 to put the drive device 14 into operation. The drive device 14 will pull the bar-shaped gear rod 116 to drive the negative pressure device 11, the camera device 10 and the stroke device 9 to move backward synchronously. In this process, since the contact rod 935 cooperates with the spiral guide groove 8, When the stroke device 9 moves as a whole, the contact rod 935 drives the cleaning device 93 to rotate along the axis of the stroke sleeve 91 as the rotation center under the limiting action of the spiral guide groove 8, and the spiral guide groove 8 is a spiral shape, and the spiral angle is 180 degrees, so that the contact rod 935 drives the cleaning device 93 to rotate as a whole under the limiting action of the spiral guide groove 8. At this time, the inner circular surface of the arc frame 933 contacts the front end of the camera device 10, so that during the overall rotation of the cleaning device 93, the arc frame 933 will scrape the front end of the camera device 10, thereby achieving the cleaning effect on the front end of the camera device 10. When the negative pressure Device 11, camera device 10 and stroke device 9 move backward synchronously, and negative pressure is formed in the space of the inner cavity of the front stroke hole 4 located at the front end of the camera device 10. At this time, the gas located at the rear side of the stroke device 9 will enter the negative pressure area inside the front stroke hole 4 through the upper guide hole 6 under the action of squeezing, thereby stabilizing the air pressure area inside the front stroke hole 4 and preventing part of the body fluid from being adsorbed into the interior of the front stroke hole 4. When the stroke device 9 and the camera device 10 both reach the stroke limit, the cleaning device 93 rotates 180 degrees under the limiting action of the spiral guide groove 8, and the two combined half pipes 936 are merged into a pipeline and connected to the lower half pipe 936. At the same time, since the front end of the connecting seat 111 is connected to the camera device 10, the connecting seat 111 and the front negative pressure plate 112 are also in a stopped state. At this time, the driving device 14 continues to maintain the traction on the bar gear rod 116, which will separate the front negative pressure plate 112 and the rear negative pressure plate 115, thereby forming a cavity, and the interior of the cavity is in a negative pressure state. The negative pressure acts on the interior of the liquid collecting tank 934 through the lower guide hole 13 and the pipeline formed by the combined half pipe 936, thereby extracting the liquid concentrated in the liquid collecting tank 934, thereby keeping the interior of the liquid collecting tank 934 clean.

[0056] A storage tank 7 is provided at the top of the junction of the inner walls of the front stroke hole 4 and the rear stroke hole 5, so that the camera device 10 will extend from the inside of the front stroke hole 4 during the resetting process of the device. At this time, the cleaning device 93 rotates outward under the squeezing of the camera device 10 and is finally located inside the storage tank 7.
