Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical instruments, in particular to a laparoscopic bipolar electrocoagulation forceps with adjustable angles. Background Art
[0002] With the application of minimally invasive technology, laparoscopic surgery is gradually replacing traditional open surgery. Due to women's love of beauty and their higher requirements for abdominal scars, laparoscopic surgery is particularly widely used in gynecological surgery. Ovarian cysts, uterine fibroids, ectopic pregnancy, endometrial cancer, and cervical cancer can all be performed with laparoscopic surgery. Currently, the laparoscopic technology that is more widely used in clinical practice is the multi-hole laparoscope. The surgeon is mainly located on the patient's left side and uses laparoscopic instruments to operate.
[0003] At present, uterine fibroids are a common and frequently occurring gynecological disease, and laparoscopic hysterectomy is a relatively common operation in gynecological minimally invasive surgery. Because laparoscopic operating instruments are currently long-arm straight instruments, they cannot adjust a large angle. They can only use the abdominal incision to punch holes to place instruments and forceps to create a certain angle with the tissue. The adjustment angle is small and cannot be adjusted over a large range. When encountering a larger uterine fibroid blocking the forceps, laparoscopic operation is more difficult. It is easier for the surgeon to handle the left uterine artery on the left side of the patient. If a larger uterus or right-sided uterine fibroids is encountered, the surgeon on the left side of the patient uses a straight bipolar electrocoagulation forceps to handle the right uterine artery of the uterus. Due to the obstruction of the uterine fibroids, the right uterine artery cannot be handled at the internal cervical os. The laparoscopic bipolar electrocoagulation forceps currently used in the operation are not convenient to adjust their angles during the operation, which brings inconvenience to the medical staff.

The present invention has an angle adjustment function. The laparoscopic bipolar electrocoagulation forceps can adjust its own angle according to the patient's condition during the operation by medical personnel, and adjust the angle across the right uterine fibroids to perform electrocoagulation on the right uterine artery of the internal cervical os, which effectively improves the practicality of the electrocoagulation forceps. In addition, the laparoscopic bipolar electrocoagulation forceps also has a positioning function, which can position the angle after completing the adjustment of its own angle, providing convenience for subsequent laparoscopic surgery by medical personnel.
[0029] The guide structure 7 includes a guide ring 71, a guide groove 72 and a guide ball 73. The guide ring 71 is fixed inside the fixed sleeve 6, and the number of guide rings 71 is several. The guide groove 72 is opened above and below the surface of the guide ring 71, and the adjustment rope 5 passes through the guide groove 72. The guide ball 73 is rotatably connected to the front and rear sides of the inner wall of the guide groove 72, and one side of the guide ball 73 contacts the surface of the adjustment rope 5. When the medical staff controls the adjustment rope 5 to move, the adjustment rope 5 will move inside the guide groove 72, and the guide ball 73 on the inner wall of the guide groove 72 can guide the adjustment rope 5 so that the angle of the second clamp handle 3 can be adjusted through the adjustment rope 5.
[0030] The adjusting structure 9 includes a winding roller 91, a rotating shaft 92, a gear 93, a mounting shell 94, a first driving motor 95, a first pulley 96, a second pulley 97 and a connecting shaft 98.

The first drive motor 95 is dynamically connected to the lower part of the interior of the mounting shell 94, and the output shaft of the first drive motor 95 passes through the mounting shell 94 and is fixedly connected to the front side of the second pulley 97, the connecting shaft 98 is fixed on the rear side of the first pulley 96, and one end of the connecting shaft 98 passes through the interior of the mounting box 8 and is fixedly connected to the front end of the rotating shaft 92 above. After the first drive motor 95 is turned on, the output shaft of the first drive motor 95 can drive the second pulley 97 to rotate, thereby causing the first pulley 96 to rotate, and the connecting shaft 98 drives the rotating shaft 92 inside the mounting box 8 to rotate, and the winding rollers 91 on the upper and lower sides are rotated through the gear 93, thereby performing the winding or releasing operation on the adjusting rope 5.
[0031] The gears 93 on the upper and lower sides inside the mounting box 8 are meshed with each other, the diameter of the first pulley 96 is larger than the diameter of the second pulley 97, and the first pulley 96 is connected to the second pulley 97 below through a belt. After the gear 93 rotates, the gears 93 on the upper and lower sides rotate in different directions. When the winding roller 91 on one side is winding the wire, the winding roller 91 on the other side will release the wire, thereby adjusting the angle of the second clamp handle 3. By driving the first pulley 96 to rotate by the second pulley 97, the first pulley 96 will rotate slowly, so as to fine-tune the angle of the second clamp handle 3.
[0032] The positioning structure 11 includes a threaded rod 111, a second driving motor 112, a movable block 113, a through slot 114 and a connecting plate 115. The threaded rod 111 is rotatably connected to the inside of the box body 10, the second driving motor 112 is fixed to the top of the box body 10, and the output shaft of the second driving motor 112 passes through the box body 10 and is fixedly connected to the top of the threaded rod 111. The movable block 113 is arranged on the upper and lower sides of the surface of the threaded rod 111, and the through slot 114 is opened at the upper and lower sides of the front side of the box body 10 and the upper and lower sides of the back side of the installation box 8. The connecting plate 115 is fixed to the front side of the movable block 113, and the connecting plate 115 passes through the through slot 114 and is fixedly connected to the back side of the positioning block 12. When the angle adjustment of the second clamp handle 3 is completed, the second driving motor 112 can be opened, so that the output shaft of the second driving motor 112 drives the threaded rod 111 to rotate, so that the movable block 113 drives the positioning blocks 12 on the upper and lower sides to move through the connecting plate 115, and the winding roller 91 is positioned.
[0033] The thread directions on the upper and lower sides of the threaded rod 111 are set in opposite directions, and the threaded rod 111 passes through the movable block 113 and is threadedly connected with the movable block 113. When the threaded rod 111 rotates, the movable blocks 113 on the upper and lower sides of the threaded rod 111 can rotate in opposite directions, thereby adjusting the positions of the positioning blocks 12 on both sides.
[0034] Limiting grooves 13 are provided at the upper and lower parts of the rear side of the inner wall of the box body 10, and a limiting block 14 is fixed to the rear side of the movable block 113. One side of the limiting block 14 extends to the inside of the limiting groove 13 and is slidably connected to the inner wall of the limiting groove 13. When the threaded rod 111 rotates, the limiting block 14 can limit the movable block 113 so that the movable block 113 can only move up and down on the surface of the threaded rod 111, thereby improving the stability of the positioning block 12 when moving.
[0035] The surfaces of the positioning blocks 12 facing each other are provided with arc grooves, and the surfaces of the arc grooves of the positioning blocks 12 are bonded with anti-skid pads 15, and the material of the anti-skid pads 15 is medical grade silicone rubber. When the arc grooves on the surface of the positioning blocks 12 are in contact with the surface of the winding roller 91, the anti-skid pads 15 can effectively position the winding roller 91 to prevent the winding roller 91 from rotating.
[0036] The diameter of the traction block 4 is smaller than the diameter of the fixed sleeve 6, and one side of the traction block 4 is configured in a conical shape. When the second clamp handle 3 enters the patient's body, the traction block 4 can minimize the patient's discomfort.
[0037] The outer surfaces of the traction block 4, the adjustment rope 5 and the fixed sleeve 6 are coated with a hydrophilic coating, which reduces the friction coefficient of the traction block 4, the adjustment rope 5 and the fixed sleeve 6, avoids possible puncture and friction damage, and effectively protects the patient.
[0038] Working principle: When the medical staff uses the electrocoagulation forceps to perform laparoscopic surgery, when the medical staff needs to adjust the angle of the second forceps handle 3, the medical staff first turns on the second drive motor 112, thereby moving the upper and lower positioning blocks 12 inside the installation box 8, and controls the rotation direction of the output shaft of the second drive motor 112, so that the upper and lower positioning blocks 12 are away from the surface of the winding roller 91, and the winding roller 91 is stopped. Then the medical staff turns on the first drive motor 95. The medical staff controls the rotation direction of the output shaft of the first drive motor 95 according to the needs of the operation, so that the winding rollers 91 on the upper and lower sides are one One performs the line-reeling operation while the other performs the line-releasing operation, so that the adjusting ropes 5 on the upper and lower sides move, and the traction block 4 on the surface of the second clamp handle 3 is pulled, and the second clamp handle 3 as a whole moves. When the angle of the second clamp handle 3 is adjusted to a suitable angle, the medical staff turns off the first drive motor 95 and turns on the second drive motor 112 again, and controls the rotation direction of the output shaft of the second drive motor 112, so that the positioning blocks 12 on the upper and lower sides move toward each other, and the surface of the positioning block 12 fits with the surface of the winding roller 91, thereby completing the positioning process of the winding roller 91, and then the medical staff can continue to perform subsequent laparoscopic surgery on the patient.
