Description

Technical Field

[0001] The utility model relates to the field of medical auxiliary instruments, in particular to an anti-dropping T-tube for laparoscopic surgery. Background Art

[0002] Laparoscopic surgery is a type of minimally invasive surgery. It uses a laparoscope to monitor and guide the operation on the display screen in the closed abdominal cavity to complete the exploration of diseased tissues, electrocoagulation, hemostasis, tissue separation, cutting and suturing, etc. Compared with traditional open surgery, it has the advantages of less trauma, fewer complications, and faster recovery. Laparoscopic surgery requires making several holes in the abdominal skin, passing the laparoscope, air needle and surgical instruments through the holes, and using the air needle to fill the abdomen with gas to establish pneumoperitoneum to provide sufficient surgical space. Then, the laparoscope is used to provide a surgical field of view and guide the operation of the surgical instruments.

[0003] In order to prevent surgical instruments from causing damage to the surgical hole during the operation and to establish a pneumoperitoneum channel, a poke card is often used in clinical practice to insert the surgical instrument into the abdominal hole, and then the surgical instrument and the air needle are introduced into the abdominal cavity through the poke card channel. However, the currently used poke cards have the following problems: 1. The stability problem of the poke card: when the surgical instrument enters and exits the poke card channel, the poke card is easily brought out of the abdominal hole by the surgical instrument, causing air leakage. At the same time, if the gap between the surgical instrument and the poke card channel is too large, there will still be air leakage problems; 2. The airtightness between the poke card and the cortex of the abdominal hole is insufficient, and the gas in the abdominal cavity will enter the cortex at the abdominal hole along the poke card and cause other medical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an anti-slip T-tube for laparoscopic surgery, the horizontal blocking tube of the anti-slip T-tube can be stuck on the inner wall of the abdominal hole to prevent the puncture card from being brought out of the abdominal hole due to the entry and exit of surgical instruments, and the outer wall of the vertical channel tube of the anti-slip T-tube is provided with a clamping cuff, which can not only prevent the gas in the abdominal cavity from escaping from the gap between the abdominal hole and the puncture card, but also prevent the gas from entering the cortex of the abdominal hole, thereby avoiding the occurrence of iatrogenic medical accidents.

[0005] In order to achieve the above technical effects, the utility model is implemented through the following technical solutions:

[0006] A T-tube for preventing laparoscopic surgery has a T-tube body structure consisting of a transverse retaining tube and a vertical channel tube, wherein a protruding hole is opened at the bottom of the transverse retaining tube, and the telescopic hole is located directly below the vertical channel tube, a clamping cuff is fixed on the outer wall of one end of the vertical channel tube close to the transverse retaining tube, an inner cuff is fixed in the inner wall of the vertical channel tube, a first inflation and deflation joint and a second inflation and deflation joint are led out from the end of the vertical channel tube, the first inflation and deflation joint is connected to the clamping cuff through a first conduit buried in the vertical channel tube, and the second inflation and deflation joint is connected to the inner cuff through a second conduit buried in the vertical channel tube.

[0007] Furthermore, the transverse baffle tube and the vertical channel tube are made of flexible latex tube.

[0008] The beneficial effects of the utility model are as follows: the horizontal blocking tube of the anti-slip T-tube can be stuck on the inner wall of the abdominal hole to prevent the puncture card from being brought out of the abdominal hole due to the entry and exit of surgical instruments; the outer wall of the vertical channel tube of the anti-slip T-tube is provided with a clamping cuff, which can not only prevent the gas in the abdominal cavity from escaping from the gap between the abdominal hole and the puncture card, but also prevent the gas from entering the cortex of the abdominal hole, avoiding the occurrence of iatrogenic medical accidents; the inner wall of the vertical channel tube of the anti-slip T-tube is provided with an inner layer cuff, which can further fix the puncture card to prevent the puncture card from being brought out and prevent the gas from escaping.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1-3 As shown, a T-tube for preventing laparoscopic surgery has a T-tube body structure consisting of a transverse blocking tube 1 and a vertical channel tube 2. The transverse blocking tube 1 has a protruding hole 3 at the bottom, and the telescopic hole 3 is located directly below the vertical channel tube 2. A clamping cuff 4 is fixed on the outer wall of one end of the vertical channel tube 2 close to the transverse blocking tube 1, and an inner layer cuff 7 is fixed in the inner wall of the vertical channel tube 2. A first inflation and deflation joint 5 and a second inflation and deflation joint 6 are led out from the end of the vertical channel tube 2. The first inflation and deflation joint 5 is connected to the clamping cuff 4 through a first conduit 8 buried in the vertical channel tube, and the second inflation and deflation joint 6 is connected to the inner layer cuff 7 through a second conduit 9 buried in the vertical channel tube.

[0017] In this embodiment, the horizontal baffle tube and the vertical channel tube are made of flexible latex tubes.

[0018] The specific application of the device is as follows: use a puncture device to puncture the target position of the abdomen and establish an abdominal hole, tilt the horizontal stop tube 1 of the anti-slip T-tube so that one end is inserted from the abdominal hole, continue to insert until the vertical channel tube is close to the abdominal hole and then push horizontally, and finally insert the other end of the horizontal stop tube 1 from the abdominal hole. Since the anti-slip T-tube is made of a flexible tube, it is also convenient for it to be inserted into the abdominal cavity from the abdominal hole, and then inflate the clamping cuff 4 through the first inflation and deflation joint. At this time, the anti-slip T-tube The molded tube is fixed on the side wall of the abdominal hole; then, the piercing card is inserted from the entrance of the vertical channel tube until the front end of the piercing card enters the abdominal cavity, and then the inner cuff 4 is inflated through the second inflation and deflation joint. After the inner cuff 4 is inflated, it will be fixed in the vertical channel tube. The horizontal blocking tube can prevent the piercing card from being brought out of the abdominal hole by the surgical instruments. At the same time, the clamping cuff 4 between the vertical channel tube and the cortical structure can prevent the gas in the abdominal cavity from entering the cortical tissue along the vertical channel tube and causing iatrogenic medical accidents.
