Description

Technical Field

[0001] The invention belongs to the technical field of laparoscopic auxiliary equipment, and in particular relates to a laparoscopic auxiliary device. Background Art

[0002] A laparoscope is similar to an electronic gastroscope and is a medical device equipped with a miniature camera. Laparoscopic surgery is a surgery performed using a laparoscope and its related instruments. The laparoscopic support auxiliary device is designed to solve the problem of an assistant needing to hold the laparoscope with his hands during laparoscopic surgery. It provides a stable image and operating environment through mechanical or intelligent means, thereby improving surgical efficiency and safety.

[0003] The laparoscopic support assist device in the prior art is usually operated in two ways during use. One is to insert the laparoscope into the patient's designated position, then use the support device to approach and contact the positioned laparoscope, and connect and fix the laparoscope to achieve stable support. The other way is to directly fix the laparoscope on the support assist device, and then operate after connection and fixation. The former is more difficult to fix after stable insertion, and the position of the inserted laparoscope is affected during the fixed connection process, causing displacement. Moreover, since the laparoscope has been accurately positioned, the connection method is relatively limited, and it is difficult to stably fix the connection and provide support. The latter is connected and fixed in advance, which is limited by the structure of the support device, so the actual laparoscope's operating freedom is reduced, the difficulty of accurate insertion is increased, and the overall use effect is not good.

The spring 62 is elastically reset and the block 64 is pushed to reset and nest in the corresponding annular groove 23 of the positioning curved arm 2. The telescopic arm 5 maintains stability after telescopic adjustment. Then the flexible rod 71 is held, the direction is changed and further approaches the split fixing part 8 on the inserted laparoscope, so that the adapter head 72 is sleeved on the outer side of the magnetic rod 9 at the top of the split fixing part 8 through the adapter cavity 73. The magnetic rod 9 and the split fixing part 8 are magnetically fixed to the bottom of the flexible connection component 7 again. The locking bolt 75 is slowly screwed in to complete the locking. Release both hands to complete the stable support.

[0033] Firstly, by utilizing the cooperation of the flexible connection component 7 and the split fixing part 8, and utilizing the magnetic effect of the magnetic rod 9, the split fixing part 8 can be made magnetically attractive and removable, thereby changing the clamping method of the laparoscope. The split fixing part 8 can be first fixed to the outside of the laparoscope, and manually inserted and used by medical staff.

While having extremely high automation in use, it also maintains a quick and stable support effect.

[0034] In addition, through the combined assembly of the positioning component 6, the telescopic arm 5 and the positioning curved arm 2, and in conjunction with the damping effect of the damping sleeve 4, convenient rotation can be achieved. In the rotating and telescopic states, the laparoscope can be fixed and supported at different positions, and the position locking is stable after actual telescoping.

The sleeve cavity 22 is opened in the crank arm body 21 and passes through the bottom of the crank arm body 21. The annular grooves 23 are evenly distributed in the sleeve cavity 22. The positioning component 6 includes a movable plate 61, a spring 62, a pressing rod 63 and a clamping block 64. The movable plate 61 is movably sleeved in the inner cavity of the telescopic arm 5.

One end of the spring 62 is fixedly connected to the movable plate 61, and the other end is fixedly connected to the inner cavity of the telescopic arm 5. The positioning component 6 is symmetrically distributed inside the telescopic arm 5, and one end of the pressing rod 63 movably passes through the telescopic arm 5.

[0038] By utilizing multiple groups of annular grooves 23 in cooperation with the clamping block 64, elastic clamping and fixing of different telescopic lengths can be achieved. When the movable plate 61 in the positioning assembly 6 drives the clamping block 64 to be hidden inside the telescopic arm 5, the spring 62 is elastically stretched, and after the pressing rod 63 is released, the spring 62 is elastically reset and rotated to clamp, which is convenient for quick adjustment.

The two auxiliary clamping mechanisms are symmetrically distributed up and down, and the No. 1 pad 12 is located on both sides of the No. 2 pad 13. The thickness of the No. 1 pad 12 is greater than the thickness of the No. 2 pad 13.

[0042] By utilizing the auxiliary clamping mechanism to further fill the outer space of the laparoscope, the contact area is increased, and clamping stability is provided, thereby maintaining stable support. The split support device can also quickly release the support, and the comprehensive use effect is good.

[0043] Embodiment 2: When clamping the laparoscope before use, the clamping plate 102 in the clamping mechanism 10 is rotated to move upward, and the sleeved laparoscope is clamped and fixed, while the upper and lower sets of auxiliary clamping mechanisms wrap and clamp the laparoscope, and the No. 1 pad 12 and No. 2 pad 13 distributed above and below complete the wrapping, clamping and fixing.
