Description
Technical Field
The invention belongs to the field of medical appliances, and particularly relates to an aspiration tube with a bendable and straight front end.
Background
Suction tubes are a common instrument for surgical operations, and are commonly used for sucking and removing the contents of bleeding or effusion, exudates, pus and pleuroperitoneal cavity organs in the operation, so that the operation process is clear and the chance of contamination is reduced.
In recent years, minimally invasive surgery typified by endoscopic surgery has become one of the important directions of medical development. In the endoscopic surgery, the aspiration tube needs to enter the abdominal cavity or the thoracic cavity in a small wound to achieve the function of aspirating liquid and contents, and meanwhile, the aspiration tube can also be used for treating the passive separation of some internal tissues and the application of the functions of probing some internal tissues, blocking internal tissue organs and the like.
At present, most of the suction tubes on the market are straight suction tubes at the front end or bent suction tubes at the front end, when a doctor uses, especially for an operation in the brain, the straight suction tubes at the front end are generally used first, when a difficult-to-take part is found, the straight suction tubes at the front end are taken out, the bent suction tubes at the front end are replaced, the position needing to be used is difficult to find, and the operation difficulty is increased.
Disclosure of Invention
In order to solve the problem that the operation difficulty is increased due to the fact that the existing suction tube only has one form of front end straight or front end bending, the invention provides the suction tube with the front end capable of being bent and straightened, and the suction tube can be adjusted and deformed into the form of front end bending or front end straight according to the needs in the operation process, so that the operation difficulty is greatly reduced.
The technical scheme adopted by the invention is as follows: a suction tube with a bendable and straight front end, which is characterized in that: comprises a soft tube, an outer hard tube, an inner hard tube and a limit tube; the outer hard tube is provided with a hollow tube body; the outer diameter of the inner hard tube is smaller than the inner diameter of the outer hard tube, the front end part of the soft tube forms the front end of the suction tube, and the bending angle of the front end of the suction tube can be adjusted by the limiting tube; one end of the inner hard tube is inserted into the hollow tube body of the outer hard tube, and the other end of the inner hard tube is connected with the limiting tube; the distance that the tube head at one end of the inner hard tube inserted into the hollow tube body is inserted into the front end part of the soft tube can be controlled by operating the limiting tube, so that the bending angle of the front end of the suction tube can be adjusted.
The suction tube is characterized in that: the soft pipe is sleeved on the outer wall of the outer hard pipe; the front end part of the soft pipe extends out and is positioned in front of the pipe head of the outer hard pipe; the inner rigid tube has a length longer than the outer rigid tube.
The suction tube is characterized in that: the inner wall of the soft pipe is fixedly connected with the sleeved part of the outer wall of the outer hard pipe.
The suction tube is characterized in that: the inner hard tube can be inserted into the tube head of the limiting tube to be abutted to the tube tail of the outer hard tube to stop, and the front end of the suction tube is in a straight state.
The suction tube is characterized in that: one end of the inner hard tube, which is inserted into the hollow tube body of the outer hard tube, is coated with an antibacterial coating.
The suction tube is characterized in that: the soft tube is made of medical elastic material.
The suction tube is characterized in that: the outer hard tube and the inner hard tube are all made of medical metal materials.
Through the structure, the suction tube with the front end in a bent or straight shape can be realized by adjusting the deformation in real time according to the requirement, and the technical effect of reducing the operation difficulty is realized.

Detailed Description
The suction tube with the bendable and straight front end mainly comprises a soft tube 1, an outer hard tube 2, an inner hard tube 3 and a limiting tube 4. The soft tube 1 is sleeved on the outer wall of the outer hard tube 2, the front end part of the soft tube 1 forms the front end of the suction tube, the front end part of the soft tube 1 extends out and is positioned in front of the tube head 201 of the outer hard tube 2, the sleeved part of the inner wall of the soft tube 1 and the outer wall of the outer hard tube 2 is fixed in a fixedly connecting mode, so that the soft tube 1 is fixedly sleeved on the outer wall of the outer hard tube 2, and the front end part of the soft tube 1 is provided with the tube head 101. The pipe body of the outer hard pipe 2 is hollow, an inner hard pipe 3 with the outer diameter smaller than the inner diameter of the outer hard pipe 2 can be inserted into the hollow pipe body of the outer hard pipe 2, and the length of the inner hard pipe 3 is longer than that of the outer hard pipe 2. One end of the inner hard tube 3 is inserted into the hollow tube body of the outer hard tube 2, one end of the inner hard tube 3 inserted into the hollow tube body is provided with a tube head 301, the other end of the inner hard tube 3 is connected with the limiting tube 4, and a user pushes or pulls the limiting tube 4 to synchronously drive the inner hard tube 3 to be inserted into or pulled out of the hollow tube body of the outer hard tube 2. When the suction tube is required to be in a front-end bent state, the distance of the inner hard tube 3 inserted into the hollow tube body is small, so that the distance of the inner hard tube 3 inserted into the front end portion of the soft tube 1 is small, and the tube head 301 of the inner hard tube 3 is required to be kept at a distance from the tube head 101 of the soft tube 1. At this time, due to the soft property of the soft tube itself, and the front end of the soft tube 1 has a portion in which neither the outer hard tube 2 nor the inner hard tube 3 is supported by filling, the front end portion of the soft tube 1 takes a curved shape, that is, the front end of the suction tube takes a curved shape due to injection molding. When the suction tube is required to be in a state that the front end is flat, the inner hard tube 3 is continuously inserted until the tube head 401 of the limit tube 4 abuts against the tube tail 202 of the outer hard tube 2. At this time, since the filling support of the inner rigid tube 3 is provided in the entire distal end portion of the flexible tube 1, the distal end portion of the flexible tube 1 is flat, that is, the distal end of the suction tube is flat. It can be seen that the user can control the distance the tip 301 of the inner rigid tube 3 is inserted into the front end portion of the flexible tube 1 by manipulating the stopper tube 4, so that the stopper tube 4 can play a role of regulating the bending angle of the front end portion of the flexible tube 1. The end of the inner hard tube 3 near the tube head 301 is coated with an antibacterial coating, which has antibacterial and bactericidal properties, and can reduce the friction coefficient with the soft tube 1 and increase the smoothness.
The flexible tube 1 may be a medical elastic material, the outer rigid tube 2 may be a medical metal material, and the inner rigid tube 3 may be a medical metal material.
