Description

Carry the peritoneal cavity drainage tube of the planning function

Technical field

The utility model belongs to medical instrument technical field, specifically a kind of peritoneal cavity drainage tube for carrying the planning function.

Background technology

Easily patient is caused peritoneal abscess occur with severe pancreatitis and some other infectious diseases.In order to subtract Few wound to patient, the method for currently used treatment peritoneal abscess is puncture drainage, and PTCD pipes are punctured to vomica, right Pus is drained, and carries out minimally-invasive treatment.But a diameter of 2.67mm and 3.33mm of currently used PTCD pipes, caliber is small, Caused slough and purulence tongue can be caused to block to it in some patientss body, be drained so as to need to change extra heavy pipe, still PTCD pipes puncture sinus it is smaller, extra heavy pipe can not be implanted into, at present in hyperphoric extra heavy pipe commonly use method be first by PTCD pipes from Extracted in patient's vomica, then sinus is progressively expanded using expanded balloon, then replanted into extra heavy pipe, but used this Method easily shifts when expanding sinus, and extra heavy pipe is not easy to be placed into accurate position, it is necessary to make repeated attempts, and wastes time and energy, And add the pain of patient.

Utility model content

The purpose of this utility model is to provide a kind of peritoneal cavity drainage tube for carrying the planning function rational in infrastructure, solved During hyperphoric extra heavy pipe, it is not easy to the problem of extra heavy pipe is placed into accurate location.

The purpose of this utility model realizes that it includes PTCD pipes, air bag and gas tube by such technical scheme, The PTCD pipes front end is provided with crimping segment, and the side wall of the crimping segment is provided with conduction hole, and the air bag is column, the PTCD Pipe is fixed on the location mid-shaft of the air bag, and the front end of the air bag is fixed on close to the crimping segment, the rear end of the air bag The rear end of PTCD pipes, the gas tube are located at the inside sidewalls of PTCD pipes, are provided with after one end expenditure PTCD pipes of the gas tube Inflation inlet, the other end are connected with the front portion of air bag blister cavities, and sleeve pipe, the cross section of the tube chamber of described sleeve pipe are arranged with the air bag Identical with cross section size during air bag unaerated, the front end of the air bag is provided with development part.

Further, the forward end of the crimping segment is bullet shape.

Further, described sleeve pipe is weak elastomeric flexible sleeve pipe.

Further, the development part is the becket for being set in air bag front end.

In summary, the beneficial effects of the utility model are：

Concentrated water in using vomica of the peritoneal cavity drainage tube provided by the utility model for carrying the planning function to patient is drawn During stream, first, using metal tube insertion PTCD pipes, metal tube is moved to the front end of PTCD pipes, the crimping segment of PTCD pipes front end It is straight by metal tube top.Then, puncture needle is inserted in metal tube, puncture needle, metal tube and PTCD are managed together under ultrasound guidance Puncture enters patient's body, until the development part of the air bag front end on PTCD pipes reaches vomica, puncture needle is then extracted out, along metal Pipe is put into seal wire, and the position of PTCD pipes front end is finely tuned further according to seal wire, then extracts metal tube and seal wire, the front end of PTCD pipes Crimping segment recovers rolled state, you can the concentrated water in vomica is drained；When there is slough and purulence tongue is made to PTCD pipes Into during obstruction, metal tube is inserted into PTCD pipes, Duan Dingzhi is batched into PTCD pipes front end, then led again along metal tube insertion Silk, sinus opening is moved to by sleeve pipe, then by air-filled pore to airbag aeration air bag expansion, sinus is supportted greatly, then will Gas in air bag is bled off, and air bag is hollow, and the peritoneal cavity drainage tube provided by the utility model for carrying the planning function is extracted along seal wire, Then extra heavy pipe can be implanted into vomica exactly by the sinus expanded along seal wire.

Sinus is directly expanded by the air bag on the peritoneal cavity drainage tube provided by the utility model for carrying the planning function, caused The sinus that one position accurately expands, make that once just original position can be reached during implantation extra heavy pipe, it is time saving and energy saving, reduce trouble The pain of person, and when there is bleeding in sinus hemostasis by compression can also be carried out to sinus；Sleeve pipe is set, it is different in implantation depth When, sleeve pipe can be moved as needed, sleeve pipe is located at the opening of sinus, so as to air bag expansion arc during restricted charging Length, the inflation of part of the air bag outside sinus can be limited, only part of the air bag in sinus mouth and sinus is entered Row inflation, improves aeration speed, and then improves the speed of sinus expansion；The crimping segment of PTCD pipes front end drains in vomica When be in rolled state, bigger with the contact surface of vomica, crimping segment is provided with conduction hole, and preferably the concentrated water in vomica can be entered Row drainage；The front end of air bag is provided with becket, can show the position that air bag reaches during lower implantation under ultrasound guidance, so as to Ensure that the front end of air bag reaches vomica, ensure that in inflation, whole sinus can be expanded；The forward end of crimping segment is son Warhead form, it can guarantee that more smooth when the peritoneal cavity drainage tube provided by the utility model for carrying the planning function is implanted into, moreover it is possible to subtract Few damage to sinus；Sleeve pipe is weak elastomeric flexible sleeve pipe, will not be swollen, can limit the air bag quilt outside sinus mouth well Swell, prevent sinus mouth by spalling.
