Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, in particular to a laparoscope for gastrointestinal surgery. Background Art

[0002] Laparoscopic surgery has the advantages of less trauma, clear vision, and rapid postoperative recovery. It has become the preferred and mature surgical method for treating thoracic and abdominal diseases. The laparoscope sheath is made of metal and is generally stored at room temperature after disinfection and sterilization. During laparoscopic surgery, due to the temperature difference between the lens and the abdominal cavity, when the laparoscope enters the patient's abdominal cavity, the lens is often prone to fogging, and the lens needs to be moved out of the abdominal cavity, which greatly delays the operation time; sometimes when tense surgical operations such as hemostasis are being performed, the lens is contaminated by blood, resulting in unclear vision, and the lens must be removed from the body for wiping. During this process, bleeding increases invisibly and even the best time for treatment is missed, resulting in heavy bleeding; Currently, when performing laparoscopic surgery, the laparoscope tube needs to be inserted into the abdominal cavity. Therefore, the camera at one end of the tube will be contaminated with a lot of body fluids, making the pictures taken by the camera unclear, which is not conducive to the doctor's analysis of the condition. When this happens, the laparoscope needs to be taken out of the abdominal cavity and the camera needs to be cleaned, which will undoubtedly delay the operation process, increase the operation time, and cause inconvenience in use.

A second screw rod 307 is rotatably connected to the top of the bottom plate 302 and located between the sleeve 303 and the second limiting shaft 306, and the connecting plate 305 is threadedly rotatably connected to the second screw rod 307.

[0037] By adopting the above technical solution, the second limit shaft 306 is set to achieve the effect of horizontal lifting of the short shaft 304. The second screw rod 307 rotates, so that the connecting plate 305 connected by the threaded rotation is horizontally lifted and lowered under the action of the second limit shaft 306.

[0038] A bevel gear 1 308 is fixedly connected to the outer ring of the screw rod 2 307 near the bottom, a square plate 309 is fixedly connected to the top of the bottom plate 302 near the bevel gear 1 308, a bevel gear 2 310 is rotatably connected to the side end of the square plate 309, and the bevel gear 2 310 is meshed with the bevel gear 1 308, a long shaft 311 is rotatably connected to the side end of the square plate 309, and a side end of the long shaft 311 passes through the square plate 309 and is fixedly connected to the bevel gear 2 310, and the other side end of the long shaft 311 passes through the mirror tube body 1 and is fixedly connected to the turning handle 102.

[0039] By adopting the above technical solution, the long shaft 311 rotates, thereby causing the fixedly connected bevel gear 2 310 to rotate, thereby causing the meshingly connected bevel gear 1 308 to rotate.

[0040] A vertical plate three 312 is fixedly connected to the inner cavity of the mirror tube body 1 near the short axis 304, a spray box 313 is fixedly connected to one side end of the vertical plate three 312 near the short axis 304, a spray port 314 is opened at one side end of the spray box 313 near the short axis 304, a cleaning sponge 315 is fixedly connected to the side end of the vertical plate three 312 and below the spray box 313, and the cleaning sponge 315 is at the same level as the camera body 301.

[0041] By adopting the above technical solution, the cleaning sponge 315 is annular in shape, and the inner wall of the cleaning sponge 315 is in contact with the outer circle of the camera body 301. The spray box 313 is provided to achieve the effect of spraying the outside of the camera body 301.

[0042] An infusion tube 316 is fixedly connected to the top of the spray box 313 and near one side, and the other end of the infusion tube 316 passes through the mirror tube body 1. A mounting box 317 is fixedly connected to the side end of the vertical plate 312 and located above the spray box 313. A number of evenly spaced micro fans 318 are fixedly connected to the side wall of the mounting box 317. A heating tube 319 is fixedly connected between the inner walls of the mounting box 317 near the center. A number of air outlets 320 are opened on one side end of the mounting box 317 near the short axis 304.

[0043] By adopting the above technical solution, the micro fan 318 and the heating tube 319 are set to operate the micro fan 318 and the heating tube 319 to achieve the effect of generating hot air, and then transport it to the camera body 301 through the air outlet 320 to complete the defog work of the camera body 301.

[0044] Working principle: When the present invention is used, when it is necessary to clean the camera body 301, firstly, the cleaning liquid is added into the infusion tube 316, so that the cleaning liquid is transported to the inside of the spray box 313, and then sprayed to the camera body 301 through the multiple spray ports 314, and then the handle 102 is rotated, so that the fixedly connected long shaft 311 is rotated, so that the fixedly connected bevel gear 2 310 drives the meshingly connected bevel gear 1 308 to rotate, and at this time, the fixedly connected screw rod 2 307 is rotated, so that the threaded rotation connection The connecting plate 305 drives the short shaft 304 to descend under the action of the second limiting shaft 306. The camera body 301 can be cleaned under the action of the cleaning sponge 315 during its descent. When the lens of the camera body 301 needs to be defogged, the micro fan 318 and the heating tube 319 are operated, and the hot air generated is transported to the camera body 301 through the air outlet 320, thereby completing the defog work of the camera body 301, thereby solving the problem that the laparoscope needs to be taken out of the abdominal cavity to clean the camera, which will delay the surgical process. When the doctor's hands become tired after working for a period of time and he / she needs to take a break during the operation, the motor 208 can be operated to make the two meshing second gears 206 drive the two sets of dial shafts 207 to rotate, so that the matching first gear 205 can rotate back and forth, thereby making the fixedly connected screw rod 209 rotate. At this time, the slider 212 threadably connected to it will move back and forth under the action of the limit shaft 210. While the slider 212 moves horizontally, the magnet block 215 will, under the action of multiple magnet blocks 204 and in cooperation with the spring 216 and the mounting bracket 217, achieve the effect of the vibration wheel 218 slightly shaking up and down. When the vibration wheel 218 shakes up and down, it will hit the blood vessels in the doctor's hand, thereby preventing the doctor's hand from reducing the accuracy of the operation due to long-term fatigue, thereby solving the problem of the doctor maintaining the same grip posture for a long time, which easily leads to hand fatigue and discomfort.

[0045] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
