Description

Technical Field

[0001] The invention relates to the technical field of single-port laparoscopic surgery, in particular to a single-port laparoscopic fixing device for pneumoperitoneum-free surgery. Background Art

[0002] Single-port laparoscopic surgery is a commonly used minimally invasive surgical method in abdominal surgery. The technology is mature and the surgical effect is good. The incision of single-port laparoscopic surgery is usually made at the umbilicus, which is perpendicular to the abdomen and at an angle to the surgical area. It is not on the same horizontal line, which seriously affects the exposure of the surgical field and the surgical operation. In addition, due to the soft structure of the abdominal wall itself, the incision retractor is tilted, which further increases the difficulty of the operation.

[0003] Compared with the traditional laparoscopic surgery that uses CO2 pneumoperitoneum technology to create surgical operating space, CO2 pneumoperitoneum technology requires continuous constant pressure perfusion of CO2 during surgery, which poses certain risks to the patient's surgical safety. Complications related to gas embolism, high carbon and subcutaneous emphysema laparoscopic pneumoperitoneum are endless, especially having many adverse effects on the respiratory and circulatory systems and pregnant fetuses. In addition, the surgical instruments are at an angle to each other, which deeply troubles gynecological and general surgeons.

[0004] At the same time, during laparoscopic surgery, the tension of the abdominal wall suspension caused by the pneumoperitoneum-free technique will cause the bilateral abdominal walls to gather toward the middle, squeezing the intestines to concentrate toward the middle, resulting in a smaller and narrower surgical space. In addition, the suspension device itself also occupies a certain position, hindering the movement of surgical instruments. Therefore, insufficient exposure of the surgical space and inconvenient operation are their main defects.

[0005] In addition, the existing pneumoperitoneum-free transumbilical single-port laparoscopic surgery has an incision operation located at the navel, but because the incision retractor inserted into the navel is perpendicular to the abdomen, and the gynecological surgical area is located in the pelvic cavity, the entrance and the surgical area are at an angle and are not on the same horizontal line, which seriously affects the exposure of the surgical field and the surgical operation. The existing pneumoperitoneum-free transumbilical single-port laparoscopic surgery is generally performed by the suspension method. During the operation, Kirschner wires and abdominal wall suspensions are used to suspend the abdominal wall. The single-port puncture point is located at McBurney's point or anti-McBurney's point. There are also improvements that make 3 to 5 small incisions in the abdominal wall near the navel. Through the small incisions, the abdominal wall is pulled up and suspended and fixed on the external suspension frame with steel wire to achieve pneumoperitoneum-free operation. As a result, the pneumoperitoneum-free suspension device is an external fixation device, which cannot completely ensure the implementation of sterile operation. At the same time, the external suspension fixation device is large, which may affect the surgical operation space and is difficult to carry, which is not conducive to the promotion of the instrument. It is fixed with multiple puncture points on both sides of the navel, and then suspended externally. It is a quadrilateral structure and is not reliable. At the same time, there are many puncture points around the navel, the operation steps are cumbersome, the operation time is prolonged, the surgical trauma is increased, the risk of postoperative infection is increased, and the healing time is also longer.

[0006] Therefore, it is urgent to design a single-port laparoscopic fixation device for pneumoperitoneum-free to solve the above problems. Summary of the invention

Through the cooperation of the curled inflatable strip, the air hose, the three-way pipe, the airbag, the slide seat and the inflatable strip, the air cushion support frame can be driven to extend and retract. Adjust the adjustment pad and the puncture fixation hole to the position of the anterior superior iliac spine, which is suitable for surgical treatment of different patients and provides sufficient space support for doctors to perform operations in the operating area. At the same time, compared with CO2 pneumoperitoneum pressure support, it is safer and can effectively prevent patients from inhaling excessive CO2 and effectively prevent the pneumoperitoneum pressure from being too high, causing pressure injury symptoms in patients. It also provides doctors with a more suitable line of sight for surgery, meets the actual needs of doctors during surgery, effectively reduces the intensity and time of doctors' operations, and also reduces the damage of steel wire to the abdominal wall.

[0021] 2. The single-port laparoscopic fixation device for pneumoperitoneum-free is configured as a hollow structure through the inner cavity of the curled inflatable strip, thereby providing sufficient expansion space for the airbag and preventing the airbag from being skewed and twisted inside the curled inflatable strip.

[0053] Working principle: When the doctor performs a pneumoperitoneum-free laparoscopic surgery, he uses a scalpel to make a puncture hole below the umbilicus 2 of the human abdomen 1. The hole shape is the same as the size of the incision retractor 5. Then the doctor embeds the incision retractor 5 into the puncture hole. Then the incision retractor 5 drives the two adjustment pads 8 and the two puncture fixing holes 9 toward the position of the anterior superior iliac spine 4 of the pelvis 3 through the regulator 6. Then the medical staff at the side operates the start button on the control switch 106 and turns on the small air pump 105. The small air pump 105 generates gas that is divided into two paths through the three-way pipe 104 and evenly enters the gas delivery hose 102. The gas then enters the gas delivery hose 102 through the gas delivery hose 102. The airbag 107 is filled with gas, and as the gas flows in, the volume of the airbag 107 gradually expands. Since the airbag 107 is in the shape of a long strip, the expanded airbag 107 drives the slide seat 109 to slide in the curled inflatable strip 101, and also drives the reset elastic rope 15 to stretch. As the sliding sleeve 14 slides on the surface of the sliding column 13, the sealing ring 16 seals the inflatable strip 1010 and the curled inflatable strip 101, so that the slide seat 109 drives the inflatable strip 1010 to move toward the anterior superior iliac spine 4. At the same time, as the inflatable strip 1010 is extended and stretched, the slider 12 slides in the slide groove 11, so that the inflatable strip 101 0 drives the air cushion support frame 7 to stretch and extend, providing auxiliary extension assistance for the adjustment pad 8. Since the material of the adjustment pad 8 is an inflatable soft material, the inflatable strip 1010 drives the adjustment pad 8 to fit closely with the surface of the anterior superior iliac spine 4, and during the air supply and expansion process of the air bag 107, the air pressure sensor 108 senses the air pressure inside the air bag 107 in real time. When the air pressure inside the air bag 107 is too high, a signal can be sent to the control switch 106, and the control switch 106 controls the small electric control valve 103 to electrically reduce the air flow in the air supply hose 102. At the same time, the control switch 106 controls the alarm buzzer to start the surrounding medical The nurse will give a voice alarm so that the medical staff can quickly take corresponding measures. Then the doctor will perform pneumoperitoneum-free laparoscopic surgery on the patient. When the doctor needs to reset and retract the adjustment pad 8 after the operation, the small electric control valve 103 will open at the maximum angle to discharge the gas in the airbag 107 through the gas supply hose 102. When the elastic rope 15 elastically retracts when the stretching state is reset, the airbag 107 is driven to shrink and reset through the slide 109. At the same time, the slide 109 also drives the adjustment pad 8 away from the surface of the anterior superior iliac spine 4 through the inflation strip 1010. Then the incision retractor 5 is taken out and the incision position can be sutured.
