Description
Technical Field
[0001] The present invention relates to the technical field of laparoscopy, and more particularly to a gynecological and obstetric laparoscope with a bendable probe. Background Art
[0002] Laparoscope is similar to electronic gastroscope, which is a medical device with a miniature camera. Laparoscopic surgery is a surgery performed using laparoscope and related instruments. With the development of medical science and technology, laparoscopic technology has been widely used in various clinical departments, and its application in obstetrics and gynecology is also expanding. Laparoscopic technology is a minimally invasive surgery. By inserting the laparoscope into the patient's body, the probe at the front end of the laparoscope allows the doctor to clearly see the tissues and organs in the pelvic and abdominal cavities, so that a clear diagnosis can be made quickly, and necessary surgical treatment can be performed under laparoscopy. During laparoscopic surgery, disinfection is first performed, followed by artificial pneumoperitoneum. After the pneumoperitoneum is established, an operation channel is established. According to the needs of the operation, a surgical incision is made and a sheath is inserted. The laparoscope is connected to a cold light source, a TV camera, and a video recording system, and inserted into the abdominal cavity through the sheath to observe the lesions of the uterus, fallopian tubes, ovaries, etc. The intra-abdominal image is reflected on the TV screen through the optical conversion system, and the corresponding surgical operation is performed. After the operation, the abdominal gas is released, the puncture needle with the cannula is pulled out, the incision is sutured, and covered with sterile gauze. When currently used, laparoscopes can be bent at a certain angle, but the bending angle is small. Therefore, after the probe enters the human body, it is inconvenient to use.

[0024] In the embodiment of the present application, when the bending and rotating mechanism 2 of the present application is in operation, the telescopic mechanism 3 will bend or rotate. Since the bending and rotating mechanism 2, the telescopic mechanism 3 and the movable probe 4 will enter the patient's body, the first rubber sleeve 5 will wrap and seal the junction between the bending and rotating mechanism 2 and the telescopic mechanism 3 to prevent various tissue fluids in the body from entering the bending and rotating mechanism 2 or the bending and rotating mechanism 2 to affect its operation. The telescopic mechanism 3 will be telescoped, so the second rubber sleeve 6 will wrap and seal the telescopic part of the telescopic mechanism 3 to prevent the telescopic mechanism 3 from being affected, and the first rubber sleeve 5 and the second rubber sleeve 6 themselves are supported by a telescopic elastic rubber material, so that they can be stretched without being damaged as the bending and rotating mechanism 2 and the telescopic mechanism 3 move.
[0025] Reference Figure 3 , Figure 4 , Figure 5 as well as Figure 8The bending and rotating mechanism 2 includes a placement box 201, a first gear box 206 is fixedly connected inside the placement box 201, a servo motor 205 is fixedly connected to the bottom end of the first gear box 206, an output shaft 207 is fixedly connected to the top end of the first gear box 206, an output bevel gear 208 is fixedly connected to the top end of the output bevel gear 208, a connecting bevel gear 209 is meshed with the top end of the output bevel gear 208, a fixed shaft 217 is fixedly connected inside the connecting bevel gear 209, a bending connecting plate 210 is fixedly connected to the side of the fixed shaft 217, the top end of the bending connecting plate 210 is fixedly connected to the bottom end of the telescopic mechanism 3, a second gear box 212 is fixedly connected to the side of the first gear box 206, and the bottom end of the second gear box 212 is fixedly connected to The motor 211 is rotated, and the top of the second gear box 212 is fixedly connected to the rotating shaft 213, the top of the rotating shaft 213 is fixedly connected to the rotating gear 214, the side of the rotating gear 214 is meshed with a connecting gear ring 215, the top of the connecting gear ring 215 is fixedly connected to the rotating disk 204, the first gear box 206 includes a supporting box 2061 that can be supported, the top of the servo motor 205 is fixedly connected to the motor shaft 2062, the motor shaft 2062 is located inside the supporting box 2061, and the side of the motor shaft 2062 is fixedly connected to the first gear 2063, the side of the first gear 2063 is meshed with the second gear 2064, and the inside of the second gear 2064 is fixedly connected to the bottom end of the output shaft 207.
[0026] In the embodiment of the present application, after the servo motor 205 is started, the output shaft 207 can be driven to rotate through the first gear box 206. When the output shaft 207 rotates, the output bevel gear 208 is driven to rotate. When the output bevel gear 208 rotates, the fixed shaft 217 inside it is driven to rotate through the connecting bevel gear 209. When the fixed shaft 217 rotates, the bending connecting plate 210 is driven to rotate. The bending connecting plate 210 rotates in different directions with the forward and reverse rotation of the output shaft 207. The bending connecting plate 210 drives the telescopic mechanism 3 and the movable probe 4 on the telescopic mechanism 3 to bend, thereby achieving a bending effect. When the rotating motor 211 is started, the rotating shaft 213 can be driven to rotate through the second gear box 212. When the rotating shaft 213 rotates, the rotating gear 214 drives the rotating shaft 213 to rotate. The movable disk 204 rotates, thereby causing the telescopic mechanism 3 to drive the movable probe 4 to rotate. Therefore, the movable probe 4 can be rotated while bending, thereby improving the visualization range of the movable probe 4, and facilitating a more comprehensive observation of the patient's lesion. In addition, it should be noted that the servo motor 205 and the rotating motor 211 output through the shaft connected to the center when outputting. The present application sets a first gear box 206 and a second gear box 212 above the servo motor 205 and the rotating motor 211, so that the output positions of the output shaft 207 and the rotating shaft 213 are close to the middle of the rotating disk 204, thereby achieving a space-saving effect. The internal structures of the first gear box 206 and the second gear box 212 are the same.
[0027] Reference Figure 3 , Figure 4 as well as Figure 5 The top of the placement box 201 is fixedly connected with a support tube 202, the interior of the support tube 202 is fixedly connected with a limit ring 203, the side of the rotating disk 204 is provided with a slide groove compatible with the limit ring 203, the interior of the rotating disk 204 is provided with a avoidance hole for the output shaft 207 to pass through, and the diameter of the avoidance hole in the rotating disk 204 is larger than the diameter of the output shaft 207, the top of the rotating disk 204 is fixedly connected with a support plate 216, the side of the top of the support plate 216 is fixedly connected with a support ring 218, the output bevel gear 208 is located inside the support ring 218, and the interior of the support ring 218 is provided with a avoidance hole for accommodating the output bevel gear 208.
[0028] In the embodiment of the present application, the rotating disk 204 will rotate under the drive of the connecting gear ring 215. In order to ensure the stability of the rotating disk 204 during rotation, a limit ring 203 is provided inside the support cylinder 202. The rotating disk 204 rotates on the side of the limit ring 203 to ensure the stability of the rotating disk 204 during rotation. A avoidance hole for the output shaft 207 to pass through is provided inside the rotating disk 204 to avoid the output shaft 207 from affecting the rotating disk 204 during rotation. In addition, a avoidance hole for the output shaft 207 to pass through is synchronously provided inside the connecting gear ring 215. Figure 5 As shown, the bending connecting plate 210 will cause the first rubber sleeve 5 to be stretched when it rotates, so a support ring 218 is provided on the side of the support plate 216, and the support ring 218 will support the first rubber sleeve 5, so that when the first rubber sleeve 5 is stretched, it will not contact with the output bevel gear 208 and cause the output bevel gear 208 to damage the first rubber sleeve 5.
[0029] Reference Figure 6 and Figure 7The telescopic mechanism 3 includes a bending rod 301 that can move with the bending and rotating mechanism 2. A mounting groove is provided at the top of the bending rod 301. An electromagnet 305 is fixedly connected in the mounting groove of the bending rod 301. A magnetic block 306 is provided above the electromagnet 305. The magnetic block 306 is located in the mounting groove of the bending rod 301. A connecting rod 307 is fixedly connected to the top of the magnetic block 306. The moving rod 302 is fixedly connected to the top of the connecting rod 307. A supporting spring 30 is movably sleeved on the side of the connecting rod 307. 8. The support spring 308 is located in the installation groove of the bending rod 301. The top of the side of the bending rod 301 is fixedly connected to the limiting cylinder 303. The side of the moving rod 302 is provided with a limiting groove, and the limiting groove of the moving rod 302 is movably connected with a limiting slider 304. The limiting slider 304 is away from the side of the moving rod 302 and is fixedly connected to the inside of the limiting cylinder 303. The top of the inside of the limiting cylinder 303 contacts the bottom end of the moving rod 302. The top of the moving rod 302 is fixedly connected to the bottom end of the first rubber sleeve 5.
[0030] In the embodiment of the present application, the electromagnet 305 is energized in the forward direction and generates a magnetic repulsion force with the magnetic block 306. After the magnetic repulsion force between the electromagnet 305 and the magnetic block 306 is greater than the elastic force of the support spring 308 when it is compressed, the magnetic block 306 will move away from the electromagnet 305. When the magnetic block 306 moves, it drives the moving rod 302 to move through the connecting rod 307. When the moving rod 302 moves, it drives the movable probe 4 to move. Therefore, the movable probe 4 can be accurately moved over a small distance, assisting medical personnel to perform precise movement, so that the movable probe 4 can reach the preset position more accurately. When the moving rod 302 is moving, the limit slider 304 slides in the limit groove of the moving rod 302, so that the moving rod 302 is more stable when moving. In addition, the second rubber sleeve 6 will completely wrap the bending rod 301 and the moving rod 302. When it is extended and retracted, various tissue fluids will not enter the bending rod 301 or the moving rod 302.
[0031] The working principle of the present invention is as follows: after artificial pneumoperitoneum is established on the patient, a surgical channel is constructed and a sheath is inserted, the movable probe 4 is inserted into the sheath and moved inside the sheath, and after moving to a suitable position, the servo motor 205 is started, and when the servo motor 205 is started, the output shaft 207 is driven to rotate through the first gear box 206, and when the output shaft 207 rotates, the output bevel gear 208 is driven to rotate, and when the output bevel gear 208 rotates, the fixed shaft 217 inside is driven to rotate through the connecting bevel gear 209, and when the fixed shaft 217 rotates, the bending connecting plate 210 is driven to rotate, and the bending connecting plate 210 rotates in different directions with the forward and reverse rotation of the output shaft 207, and the bending connecting plate 210 drives the telescopic mechanism 3 and the movable probe 4 on the telescopic mechanism 3 to bend, so as to observe the inside of the patient's body; When the movable probe 4 is bent, the rotating motor 211 is started and drives the rotating shaft 213 to rotate through the second gear box 212. When the rotating shaft 213 rotates, the rotating disk 204 is driven to rotate through the rotating gear 214. When the rotating disk 204 rotates, the supporting plate 216 is driven to rotate. When the supporting plate 216 rotates, the bending connecting plate 210 is driven to rotate through the fixed shaft 217. At this time, the bending connecting plate 210 can drive the movable probe 4 to rotate through the telescopic mechanism 3. Therefore, the movable probe 4 can also rotate while bending, thereby improving the visualization range of the movable probe 4 and facilitating a more comprehensive observation of the patient's lesion. When the movable probe 4 is bent and rotated, the electromagnet 305 is energized in the positive direction and generates a magnetic repulsion force with the magnetic block 306. After the magnetic repulsion force between the electromagnet 305 and the magnetic block 306 is greater than the elastic force of the support spring 308 when it is compressed, the magnetic block 306 moves away from the electromagnet 305. When the magnetic block 306 moves, it drives the moving rod 302 to move through the connecting rod 307. When the moving rod 302 moves, it drives the movable probe 4 to move. Therefore, the movable probe 4 can be accurately moved over a small distance, assisting medical personnel to perform accurate movement, so that the movable probe 4 can reach the preset position more accurately, thereby improving the overall operation efficiency. Improve work efficiency and reduce operation time. When the current passed through the electromagnet 305 decreases, the magnetic repulsion between the electromagnet 305 and the magnetic block 306 is less than the elastic force of the compressed support spring 308, and the magnetic block 306 will move closer to the electromagnet 305. Therefore, the movable probe 4 of the present application can move in different directions. After the movement, the movable probe 4 can be taken out. When the movable probe 4 moves, the first rubber sleeve 5 will wrap and seal the junction of the bending and rotating mechanism 2 and the telescopic mechanism 3, and the second rubber sleeve 6 will wrap and seal the telescopic part of the telescopic mechanism 3 to avoid the bending and rotating mechanism 2 and the telescopic mechanism 3 being affected.
