Description

Anastomat with good sealing performance for laparoscope

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to an anastomat for peritoneoscope that the leakproofness is good.

Background

When the circular anastomat of the laparoscope is used for minimally invasive surgery, the front end is arranged in the abdominal cavity, the rear end is arranged outside the abdominal cavity, in order to maintain the stability of the abdominal pressure, a sealing ring is added between the gap between the bent push rod and the bent sleeve, the leakage of gas in the abdominal cavity is reduced during surgery, and the operation of doctors is convenient.

However, the groove on the bent push rod is a U-shaped groove at present, the contact area of the groove and the sealing ring is small, only one sealing ring is arranged for sealing, the bent push rod has the possibility of air leakage when sliding in the bent sleeve, and after the single sealing ring is abraded through sliding for many times, the sealing structure of the device is damaged, the service life is short, and great risk is caused when the operation is performed again.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of air leakage possibility and short service life in the prior art, and providing the anastomat for the laparoscope with good sealing performance.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a anastomat for peritoneoscope that leakproofness is good, includes curved pipe box, the inside slip of curved pipe box is equipped with curved push rod, the hemisphere groove has been seted up in the outside of curved push rod, the fixed sealing washer that is provided with in inside in hemisphere groove, the both sides of curved push rod are all fixed and are provided with the elastic component.

Preferably, the number of the sealing rings is two.

Preferably, the bent push rod and the elastic piece are welded and fixed.

Preferably, the elastic element is made of elastic metal material, and the outer side of the elastic element is arc-shaped.

The utility model has the advantages that: the utility model has the advantages of simple structure and reasonable design, change "U" type groove on the curved push rod into hemispherical hemisphere groove, increased the area of contact between sealing washer and the groove, promote sealed effect, through the design of addding a sealing washer and elastic component, further hoisting device's sealing performance, thoroughly stopped the possibility of gas leakage, moreover after sealing washer sliding wear many times, outside elastic component still can play sealed effect, prolonged the life of apparatus, ensure that the safety of operation goes on.

fig. 2 is an enlarged view of the stapler for laparoscope with good sealing performance, which is shown in the position marked by the numeral a of the utility model.

In the figure: 1 bent pipe sleeve, 2 bent push rods, 3 hemispherical grooves, 4 sealing rings and 5 elastic parts.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, an anastomat for laparoscope with good sealing performance comprises a curved pipe sleeve 1, wherein a curved push rod 2 is assembled in the curved pipe sleeve 1 in a sliding manner, a hemispherical groove 3 is formed in the outer side of the curved push rod 2, a sealing ring 4 is fixedly arranged in the hemispherical groove 3, elastic parts 5 are fixedly arranged on two sides of the curved push rod 2, the number of the sealing rings 4 is two, the curved push rod 2 and the elastic parts 5 are fixedly welded, the elastic parts 5 are made of elastic metal materials, the outer side of each elastic part 5 is arc-shaped, the utility model has the advantages of simple structure and reasonable design, the U-shaped groove on the curved push rod 2 is changed into the hemispherical groove 3, the contact area between the sealing ring 4 and the groove is increased, the sealing effect is improved, the sealing performance of the device is further improved by additionally arranging the sealing ring 4 and the elastic parts 5, and the possibility of air, and after the sealing ring 4 is worn by sliding for many times, the external elastic part 5 still can play a sealing effect, the service life of the instrument is prolonged, and the safe operation is ensured.

In the embodiment, when the device is used for minimally invasive surgery, the front end of the instrument is in the abdominal cavity, the rear end of the instrument is outside the abdominal cavity, the bent push rod 2 is positioned in the cavity of the bent pipe sleeve 1, the sealing rings 4 on the two sides are tightly attached to the inner wall of the bent pipe sleeve 1, the inner side of the sealing ring 4 is tightly contacted with the hemispherical groove 3, the contact area between the sealing ring 4 and the groove is increased due to the fact that the U-shaped groove is changed into the hemispherical groove 3, the sealing effect is better, meanwhile, the elastic piece 5 is propped open in the cavity, the sealing performance is further improved, the outer side of the elastic piece 5 is designed into the arc shape, the elastic piece 5 can easily slide in the bent pipe sleeve 1, the friction between mechanisms is small, when the elastic piece 5 is pushed into the bent pipe sleeve 1, the elastic piece 5 can adapt to the shape of the bent pipe sleeve 1 and can be taken in the groove hole along the inner wall, the service life of the instrument is prolonged, and the safe operation is ensured.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
