Description

 The invention relates to medical equipment and can be used to impose and tighten the dressing loop when performing endoscopic interventions.

 A device is known for endoscopically applying a dressing loop in the form of a hollow tube in which the free end of the loop thread is placed, with an outlet made under the loop assembly (Laparoscopic Biliary Surgery, page 92, fig 4.35). The device is inserted through the sleeve of the trocar into the abdominal cavity, a loop is applied to the stump, for example, a vessel or appendix, and the loop pulls the loop through the free end of the thread and the tube is removed from the sleeve of the trocar.

 The disadvantage of this device is the use of the sleeve of the trocar (port) for the entire period of introduction into the abdominal cavity, installing the loop in the selected place and tightening it.

 The objective of the invention is to provide a device for endoscopic application of a dressing loop, allowing the use of a trocar sleeve (port) only for the period of its introduction into the abdominal cavity.

 The problem is solved in that the known device for endoscopic application of a dressing loop containing a hollow tube for accommodating the free end of the thread with an outlet made under the loop assembly, according to the invention additionally contains two interchangeable interchangeable tips connected to the tube and containing means for fastening the free end of the thread loops, the first tip made in the form of a needle, and the second in the form of a tube with a thrust placed in it.

 To reduce the invasiveness of the intervention, it is advisable to make the working end of the needle blunt.

 The presence of a replaceable tip in the form of a needle connected to the tube allows after insertion of the device through the sleeve of the trocar to pierce the front abdominal wall from the inside and install the device in a puncture made, thereby freeing the sleeve of the trocar. The second interchangeable tip, made in the form of a tube with a rod placed in it, allows you to extend the first tube to the required size and install the loop in a given place and tighten it.

 The implementation of the working end of the needle blunt allows you to prevent damage to blood vessels when piercing from the inside of the front abdominal wall.

In FIG. 1, 2 shows a device for endoscopic application of a dressing loop with a removable tip in the form of a needle;
figure 3 - interchangeable tip in the form of a tube;
in FIG. 4, 5 - a device with a replaceable tip in the form of a tube.

 The device for endoscopic application of the dressing loop contains a hollow tube 1 with an outlet 2 made under the sliding node 3 of the loop 4, the free end 5 of the thread being placed in the tube 1. The device contains a removable tip 6 made in the form of a needle with a blunt end, at the opposite end which has a hook 7 for fixing the free end 5 of the loop 4. The tip 6 is detachably connected to the tube 1. The second interchangeable tip is made in the form of a tube 8, inside which there is a rod 9 with a hook 10 d placed on one end For fastening the free end 5 of the thread and the handle 11 on the other end. The tube 8 is detachably connected to the tube 1 by means of a conical connection 12.

 A device with a replaceable tip 6 installed on the tube 1 (Fig. 1) is inserted through the trocar sleeve into the abdominal cavity with a clamp or a special manipulator (RF Patent N 2062051). In the selected place, the front abdominal wall is pierced with a needle 6 from the inside and the device is brought out onto the skin surface until the tip 6 is connected to the tube 1. The tip 6 is disconnected from the tube 1, the free end 5 of the loop 4 threads are disconnected from the hook 7 of the replaceable tip 6. Connect the tube 1 s another interchangeable tip (figure 3), for this, the hook 10 of the rod 9 is connected to the free end 5 of the thread and then connect the tubes 1 and 8 using a conical connection 12. The device is ready to install the loop 4 in the desired place and tighten it. Loop 4 is thrown onto the selected object, rod 9 is moved by handle 9 and the free end 5 of the thread connected to it, while the sliding unit 3 is lowered by the end of tube 1 and tightens loop 4. After tightening the loop 4, the thread is cut off at the base of unit 3, removed from the tubes 1 and 8 and remove the latter from the abdominal cavity through a puncture.

 Using the proposed device requires a trocar sleeve only for the period of its introduction into the abdominal cavity, later, when installing the loop and tightening it, the device is placed in a puncture in the anterior abdominal wall made with a replaceable tip, and the trocar sleeve (port) is released to accommodate other instruments.
