Abstract

A liver puncture needle channel stopper relates to a needle channel stopper used after percutaneous transhepatic choledochus drainage, and prevents sinus tract bleeding and bile outflow after percutaneous transhepatic choledochus drainage. The technical content includes that the liver puncture needle channel stopper comprises an outer cannula (1), a blockage (4) and a pushing tube (2), the blockage (4) and the pushing tube (2) are sleeved in the outer cannula (1), the blockage (4) is pushed to a part, needing to be blocked, in the body of a patient along a guide wire (5) by the pushing tube (2), and then the pushing tube (2) pushes the blockage (4) out of the outer cannula (1) to a puncture needle channel required to be blocked so as to realize blocking operation. The liver puncture needle channel stopper has the advantages that the blockage (4) can be smoothly fed to the part, needing to be blocked, in the body of the patient, can be absorbed by tissues of the human body in a short time, and cannot cause abnormal response.

Description

The liver puncture needle pipeline packer

Technical field:

This utility model relates to a kind of percutaneous transhepatic puncture biliary drainage postoperative needle track stopper, is used for the bile duct puncture drainage tube and pulls out back shutoff sinus tract, prevents the hemorrhage and bile outflow of sinus tract.

Background technology:

At percutaneous transhepatic puncture biliary drainage postoperative, after the drain thoroughly, need pull out drainage tube.But generally speaking, because the T-type drainage tube retention time is longer, after drainage tube is pulled out, has sinus tract and form, bile is excessive along sinus tract, makes drain sinus tract indolence.If bile flows into the abdominal cavity along sinus tract in the liver, cause biliary peritonitis, can cause serious adverse consequences.In addition, after the treatment such as percutaneous transhepatic puncture radio frequency, argon helium knife, also there is hemorrhage situation in the puncture needle track, and the comparatively difficulty of needle track hemostasis that punctures in the liver is a severe complications, jeopardizes patient's life.

Summary of the invention:

It is a kind of at percutaneous transhepatic puncture biliary drainage postoperative that the purpose of this utility model is to provide, and prevents the hemorrhage liver puncture needle pipeline packer that outflows with bile of sinus tract.

The technology contents of this utility model is to comprise seal wire; It is characterized in that trocar sheath is enclosed within on the seal wire; Be inserted in plug successively, push pipe along seal wire again in the trocar sheath, the front end that pushes pipe is equipped with metal location thing, and the front end of trocar sheath is gradually thin shape; Plug is pushed out in the gradually thin shape opening in the effect lower edge that pushes pipe thrust, and shutoff is in needle track.

The gradually thin shape of trocar sheath front end can use elastomeric material, or cut channel in advance vertically.

Plug is that the gelfoam that contains the anti-inflammatory drug that stops blooding is fastened.

The advantage of this utility model is because the trocar sheath front end is gradually thin shape, makes that the position that trocar sheath is shifted onto easily needs shutoff, front end are elastomeric material or cut channel in advance vertically, and making plug be pushed out to easily needs the shutoff position; Owing to be installed with metal location thing at propelling movement pipe front end, can under X-ray or supersonic sounding, know to show its position, guarantee that plug accurately puts in place; Because plug has adopted the gelfoam that contains the anti-inflammatory drug that stops blooding to fasten, making to get into needs the position of shutoff to expand rapidly, shutoff puncture needle track, and can be absorbed by tissue in a short time, can not cause abnormal response.

The specific embodiment:

This utility model such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; The technology contents of this utility model is to comprise seal wire (5); It is characterized in that trocar sheath (1) is enclosed within on the seal wire (5); Be inserted in plug (4) successively, push pipe (2) along seal wire (5) again in the trocar sheath (1), the front end that pushes pipe (2) is equipped with metal location thing (3), and the front end of trocar sheath (1) is gradually thin shape; Plug (4) is pushed out in the gradually thin shape opening of the effect lower edge trocar sheath (1) that pushes pipe (2) thrust, and shutoff is in needle track.

The gradually thin shape of trocar sheath (1) front end can use elastomeric material, or cut channel in advance vertically.

Plug (4) is that the gelfoam that contains the lipidemia anti-inflammatory drug is fastened.

The method for using of this utility model is that seal wire (5) penetrates in the body to the affected part in advance; Trocar sheath (1) being enclosed within on the seal wire (5), is gradually thin shape opening part with pushing pipe (2) with the front end that plug (4) pushes to trocar sheath (1) along seal wire (5) again in the trocar sheath (1) again; Above-mentioned trocar sheath (1), plug (4), propelling movement pipe (2) are pushed to jointly the suitable position of body domestic demand shutoff, metal location thing (3) plays the role of positioning again; Reuse pushes pipe (2) plug (4) is pushed out in the needle track that needs shutoff from the gradually thin shape opening of trocar sheath (1), and plug (4) expands rapidly, and shutoff is in the puncture needle track of need shutoff; At last, will be except that plug (4), all the other all extract external, accomplish the shutoff operation of puncture needle track.

Claims

1. liver puncture needle pipeline packer; Comprise seal wire (5), it is characterized in that trocar sheath (1) is enclosed within on the seal wire (5), be inserted in plug (4) successively, push pipe (2) along seal wire (5) again in the trocar sheath (1); The front end that pushes pipe (2) is equipped with metal location thing (3); The front end of trocar sheath (1) is gradually thin shape, and plug (4) is pushed out in the gradually thin shape opening in the effect lower edge that pushes pipe (2) thrust, and shutoff is in needle track.

2. liver puncture needle pipeline packer according to claim 1 is characterized in that the gradually thin shape of trocar sheath (1) front end can using elastomeric material, or cut channel in advance vertically.

3. liver puncture needle pipeline packer according to claim 1 is characterized in that plug (4) is that the gelfoam that contains the anti-inflammatory drug that stops blooding is fastened.
