Description

Technical Field

[0001] This utility model belongs to the technical field of laparoscopic puncture instruments, and mainly relates to an adjustable self-fixing puncture device with a balloon. Background Technology

[0002] Subcutaneous emphysema is a common complication of laparoscopic surgery, mostly due to excessively high gas pressure. This causes gas to leak into the subcutaneous tissue around the trocar, leading to increased end-tidal carbon dioxide partial pressure. This affects the duration of surgery and anesthesia, and increases the risk of complications such as gas embolism and acid-base imbalance. Current adjustable self-fixing trocars with balloons cannot solve these problems. Utility Model Content

[0026] Example 1: See Figure 1-2 :

[0027] An adjustable self-fixing trocar with a balloon includes a laparoscopic rear end catheter 1 (this is prior art and will not be described in detail) and a laparoscopic front end catheter 2. The front end of the laparoscopic rear end catheter 1 is connected to the rear end of the laparoscopic front end catheter 2. A balloon mechanism 4 is fitted onto the outer wall of the laparoscopic front end catheter 2. The balloon mechanism 4 has a balloon air delivery tube 5 communicating with its inner lumen. The other end of the balloon air delivery tube 5 is connected to a balloon valve mechanism 6.

[0028] The inner cavity of the balloon mechanism 4, corresponding to the outer wall of the laparoscope front end catheter 2, is provided with an inner balloon folding ring 41. The balloon mechanism 4 is secured to the outer wall of the laparoscope front end catheter 2 by a balloon securing mechanism 7 that is secured to the inner balloon folding ring 41.

[0029] The air supply tube 5 of the balloon is fixed to the catheter 2 at the front end of the laparoscope through the catheter fixing mechanism 3. The catheter fixing mechanism 3 is a rubber ring, which has good elasticity and is easy to operate.

[0030] The airbag mechanism 4 uses a rubber airbag or a plastic airbag. The main function of the airbag mechanism 4 is to inflate it after inflation, so that the airbag mechanism 4 fits tightly against the peritoneum to prevent gas leakage and reduce the incidence of subcutaneous emphysema.

[0031] The working principle of this utility model's adjustable self-fixing puncture device with balloon is described in [reference needed]. Figure 2 First, an incision is made in the patient's abdomen, the incision size being appropriate. The tip of the laparoscope's distal end catheter 2 is inserted into the incision (at this time, the balloon mechanism 4 is in an uninflated state). After the tip of the laparoscope's distal end catheter 2 reaches the appropriate position, air is inflated into the cavity of the balloon mechanism 4 through the balloon valve mechanism 6 and the balloon inlet tube 5. The balloon mechanism 4 inflates, adhering tightly to the peritoneum to prevent the distal end catheter 2 from slipping out, preventing gas leakage, reducing the incidence of subcutaneous emphysema, and facilitating the surgeon's operation. After the surgery, the air in the cavity of the balloon mechanism 4 is expelled through the balloon valve mechanism 6 and the balloon inlet tube 5, and the tip of the laparoscope's distal end catheter 2 is removed from the patient's abdominal incision.

[0032] The adjustable self-fixing puncture device with balloon of this invention helps prevent subcutaneous emphysema, reduces related complications caused by subcutaneous emphysema, and provides a guarantee for many complex surgeries.

[0033] Example 2: See Figure 3-5 :

[0034] Example 2 is an improvement on Example 1. The similarities will not be repeated. The difference is that the laparoscope tip catheter 2 is improved in order to improve the performance of the balloon-adjustable self-fixing trocar.

[0035] The laparoscopic anterior catheter 2 includes an anterior mid-section catheter 21 and an anterior distal catheter 22. The rear end of the anterior mid-section catheter 21 is connected to the front end of the laparoscopic posterior catheter 1. The anterior end of the anterior mid-section catheter 21 is provided with a mid-section catheter annular groove 211, and the rear end of the anterior distal catheter 22 is inserted into the mid-section catheter annular groove 211 of the anterior mid-section catheter 21.

[0036] The inner cavity of the airbag mechanism 4 is provided with airbag inner folding rings 41 at both the front and rear ends. The airbag inner folding ring 41 at the rear end of the airbag mechanism 4 is secured to the outer wall of the middle section of the front end conduit 21 by the airbag securing mechanism 7 that is secured to the airbag inner folding ring 41. The airbag inner folding ring 41 at the front end of the airbag mechanism 4 is secured to the outer wall of the end section of the front end conduit 22 by the airbag securing mechanism 7 that is secured to the airbag inner folding ring 41.

[0037] The working principle of this utility model's adjustable self-fixing puncture device with balloon is described in [reference needed]. Figure 4 First, an incision is made in the patient's abdomen, with an appropriate incision size. The tip of the laparoscope's distal end catheter 2 is inserted into the incision (at this time, the balloon mechanism 4 is in an uninflated state). After the tip of the laparoscope's distal end catheter 2 reaches the appropriate position, air is inflated into the inner cavity of the balloon mechanism 4 through the balloon valve mechanism 6 and the balloon air delivery tube 5. The balloon mechanism 4 inflates, adhering tightly to the peritoneum to prevent the distal end catheter 2 from slipping out, preventing gas leakage, reducing the incidence of subcutaneous emphysema, and facilitating the surgeon's operation. By adjusting the amount of gas inflated into the inner cavity of the balloon mechanism 4, the depth of the distal end catheter 22 inserted into the annular groove 211 of the middle end catheter 21 can be controlled, thereby adjusting the length of the laparoscope's distal end catheter 2 to suit the surgeon's surgical method, thus facilitating the surgeon, saving time, and reducing complications.

[0038] After the surgery, the gas in the inner cavity of the airbag mechanism 4 is discharged through the airbag valve mechanism 6 and the airbag delivery tube 5, and the front end of the laparoscope end catheter 2 is pulled out from the abdominal opening of the patient.

[0039] This novel adjustable, self-fixing trocar with balloon helps prevent subcutaneous emphysema, further reducing related complications and providing assurance for many complex surgeries. Simultaneously, the adjustable laparoscopic end catheter 2 facilitates surgical operations from various angles, saving surgical time.

[0040] The embodiments described above are merely preferred embodiments of the present utility model. Without departing from the spirit of the present utility model, all modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope defined by the claims of the present utility model.
