Description

A new T-tube clamp for liver transplantation

technical field

The utility model relates to the field of medical auxiliary equipment, in particular to a novel T-tube clip specially used for liver transplantation.

Background technique

In the surgical treatment of biliary tract diseases, iatrogenic bile duct injury and other operations related to the biliary tract will be accompanied by T-tube drainage. The T-tube is a special latex tube. It is easy to insert the bile duct after trimming, but it is time-consuming and labor-intensive. In addition, it requires the tacit cooperation of doctors and assistants and a wide surgical field to shorten the implantation time. In the case of laparoscopic surgery, it will cost a lot. The time will be longer, requiring the operator not only to have good laparoscopic skills but also to be patient and careful. Some operations take longer, and the process of T-tube implantation into the bile duct is more challenging for the operator in these aspects, so how to shorten it? Implantation time and improving efficiency are problems to be solved urgently.

Contents of the invention

Based on the situation encountered above, the utility model provides a new T-tube clip specially used for liver transplantation, which can effectively implant the T-tube into the bile duct, shorten the operation time, and improve the operation efficiency.

In order to achieve the above purpose, the utility model adopts the following technical solution: a new type of T-tube clamp for liver transplantation, including a first holding arm part and a second holding arm part, and the first holding arm part and the second holding arm part The same-side end of the arm is hingedly connected, the upper end of the first holding arm is connected with the first transition part, the upper end of the second holding arm is connected with the second transition part, the first transition part is connected with the second clamping part, and the second The transition part is connected to the first clamping part, the first clamping part is on the same side as the first handle part, the second clamping part is on the same side as the second handle part, the first clamping part is connected to the first bending chuck, The second clamping part is connected with the second bending clamp, the inner surface of the end of the first bending clamp is provided with a protrusion, and the inner surface of the end of the second bending clamp is provided with a groove matched with the protrusion.

The outer surfaces of the first holding arm part and the second holding arm part are respectively provided with concavo-convex patterns.

The apex angle of the bump is acute.

The protrusion is perpendicular to the inner surface of the end of the curved chuck.

The bending lengths of the first bending clamp and the second bending clamp are both 25mm or 30mm or 35mm.

The thickness of the projection after engaging with the groove is 0.3mm or 0.5mm or 0.7mm, and the width is 0.5mm or 0.8mm or 1.1mm.

The ends on the same side of the first holding arm part and the second holding arm part are hingedly connected by pins.

The new T-tube clamp for liver transplantation with the technical solution of the utility model has a simple and reasonable structure, which can make it easy for the user to hold and hold the T-tube sideways, facilitate the placement of the T-tube, effectively clamp the T-tube, and shorten the time , thereby improving surgical efficiency.

detailed description

As shown in Figures 1, 2, and 3, a new T-tube clamp for liver transplantation includes a first arm part 1 and a second arm part 2, and the first arm part 1 and the second arm The same side end of the arm part 2 is hingedly connected, the first transition part 3 is connected to the upper end of the first hand arm part 1, the second transition part 4 is connected to the upper end of the second hand arm part 2, and the first transition part 3 is connected to the second The clamping part 6, the second transition part 4 is connected to the first clamping part 5, the first clamping part 5 is on the same side as the first handle part 1, and the second clamping part 6 is on the same side as the second handle part 2 , the first clamping part 5 is connected to the first bending chuck 7, the second clamping part 6 is connected to the second bending chuck 8, the inner surface of the end of the first bending chuck 7 is provided with a bump 13, and the second bending chuck 8 The inner surface of the end is provided with a groove 12 that matches and engages with the protrusion 13 .

The outer surfaces of the first holding arm part 1 and the second holding arm part 2 are respectively provided with concavo-convex lines 11 .

The apex of the bump 13 is acute.

The protrusion 13 is perpendicular to the inner surface of the end of the curved chuck 7 .

The bending lengths of the first bending clamp 7 and the second bending clamp 8 are both 25 mm or 30 mm or 35 mm.

The thickness of the protrusion 13 after engaging with the groove 12 is 0.3 mm or 0.5 mm or 0.7 mm, and the width is 0.5 mm or 0.8 mm or 1.1 mm.

The same-side ends of the first holding arm part 1 and the second holding arm part 2 are hingedly connected by pins 10 .

When a force is applied to the holding arm 1 and the holding arm 2 at the same time, the first bending chuck 7 and the second bending chuck 8 are separated, and the separation distance can be determined by the magnitude of the applied force and its own measuring range.

When the applied force of the holding arm 1 and the holding arm 2 is cancelled, the first bending chuck 7 and the second bending chuck 8 are closed, and the protrusion 13 and the groove 12 are closed together.

The technical principle of the utility model has been described above in conjunction with specific embodiments, and these descriptions are only for explaining the principle of the utility model, and cannot be interpreted as limiting the protection scope of the utility model in any way. Based on the explanations herein, those skilled in the art can think of other specific implementations of the present utility model without creative work, and these forms will all fall within the protection scope of the present utility model.
