Description

T-shaped biliary tract drainage tube placer

Technical Field

The utility model relates to a T type biliary tract drainage tube auxiliary assembly technical field, in particular to T type biliary tract drainage tube placer.

Background

In the treatment, a T-shaped tube needs to be placed on the biliary tract for drainage, so as to achieve the following purposes: 1. draining bile to relieve biliary tract pressure; 2. support the biliary tract and prevent bile duct stenosis; 3. biliary tract imaging and flushing; 4. the second stone extraction is carried out, therefore, the T-shaped drainage tube can play the roles of draining bile and residual stone, and preventing peritonitis caused by biliary obstruction and bile leakage.

At present, when a T-shaped drainage tube is placed in an operation, a left bracket and a right bracket of the T-shaped drainage tube need to be folded, and the left bracket and the right bracket are clamped by forceps so that the left bracket and the right bracket are placed into a biliary tract after the left bracket and the right bracket are overlapped with the head ends. The support is folded about T type drainage tube and is needed to last external force forceps holder, support overlapping head end is put into and is loosened and withdraw from the pliers after the biliary tract when pliers forceps holder about, at this moment, the support can strut by oneself about the T type drainage tube, but the support is longer about the T type drainage tube, this operation difficulty, easily lead to putting the pipe difficulty, and relapse repetitious operation, easily cause the blunt nature of biliary tract drainage mouth to tear, enlarge, at this moment, drainage mouth bore and T type drainage tube pipe diameter mismatch, easily lead to the bile to leak and arouse peritonitis outward.

Therefore, a T-shaped biliary tract drainage tube placer is needed to be designed to solve the above problems, so that the T-shaped drainage tube placer is simple and easy to place and operate and is suitable for the traditional laparotomy and endoscopic surgery.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above purpose, the utility model adopts the technical proposal that:

the utility model provides a T type biliary tract drainage tube placer, is including placing pipe and push rod, it is transparent construction to place the pipe, and has elasticity, place the C type structure of cross section for having the breach under the pipe natural state, the size of C type structure inner wall slightly is greater than the cross section outline size when the support is folding and overlapping about T type biliary tract drainage tube, the push rod slides to peg graft to placing intraductally, and with place the pipe and be dismantled the connection, and there is one end to be located place the outside of the tubes, the cross section size of push rod perpendicular to on its length direction is less than the size of C type structure inner wall.

Furthermore, the placing pipe is made of transparent and nontoxic PVC materials.

Further, the length of the placing pipe is 15-20 cm.

Further, the length of the push rod is not less than the difference between the lengths of the main tubes of the placement tube and the T-shaped biliary tract drainage tube.

furthermore, the end part of one end of the push rod, which extends into the placing pipe, is provided with a push head, the push head is in a shape of ∩, wherein the left branch and the right branch of the reverse U extend out of the push rod.

Furthermore, one end of the push rod, which is positioned outside the placing pipe, is connected with a rope, and is connected with the placing pipe through the rope.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses a set up elastic, the cross section is the pipe of placing of C type structure and fixes the state after T type biliary tract drainage tube left and right sides support is folding, promote to place intraductal T type biliary tract drainage tube through setting up the push rod, thereby make T type biliary tract drainage tube stretch into in the biliary tract, this placer makes the operation of placing of T type biliary tract drainage tube become simple and easy, and can not cause the blunt nature of biliary tract drainage mouth to tear, enlarge, avoid appearing leading to the bile to leak outward and arouse peritonitis because of drainage mouth bore and T type drainage tube pipe diameter mismatch, its practicality is better, be worth promoting.

Drawings

Fig. 1 is a schematic structural view of the T-shaped biliary tract drainage tube placer of the present invention.

Fig. 2 is a structural schematic diagram of the T-shaped biliary tract drainage tube when the T-shaped biliary tract drainage tube is placed in the placement tube.

Description of the main elements

In the figure: a placing tube 1, a push rod 2, a push head 3 and a T-shaped biliary tract drainage tube 4.

The following detailed description of the invention will be further described in conjunction with the above-identified drawings.

Detailed Description

Referring to fig. 1, in a preferred embodiment of the present invention, a T-shaped biliary tract drainage tube placer includes a placement tube 1 and a push rod 2.

The placing tube 1 is of a transparent structure and has elasticity, the cross section of the placing tube 1 in a natural state is of a C-shaped structure with a notch, and the size of the inner wall of the C-shaped structure is slightly larger than the size of the outer contour of the cross section when the left and right supports of the T-shaped biliary tract drainage tube 4 are folded and overlapped. Placing pipe 1 and being used for placing the T type biliary tract drainage tube 4 after left and right sides support folding, later reducing it through external force, put into the drainage mouth again, when removing external force, place pipe 1 and can prop the drainage mouth because of its elastic action, then can the reconversion after breaking away from the drainage mouth, it can avoid present with pliers pincers clamp and cause the drainage mouth to tear, enlarge. Preferably, the placing pipe 1 is made of transparent and nontoxic PVC materials. The length of the placing tube 1 is 15-20cm so as to extend into the biliary tract.

the push rod 2 is inserted into the placing tube 1 in a sliding mode and is detachably connected with the placing tube 1, one end of the push rod 2 is located outside the placing tube 1, the size of the cross section of the push rod 2 perpendicular to the length direction of the push rod 2 is smaller than the size of the inner wall of the C-shaped structure, the push rod 2 is used for pushing the T-shaped biliary tract drainage tube 4 in the placing tube 1 and enabling the T-shaped biliary tract drainage tube 4 to move towards the inner side of the biliary tract, preferably, the length of the push rod 2 is not smaller than the difference between the lengths of the main tubes of the placing tube 1 and the T-shaped biliary tract drainage tube 4 so as to push the T-shaped biliary tract drainage tube 4 and withdraw the placing tube 1, furthermore, a push head 3 is arranged at the end portion, extending into the placing tube 1, of the push rod 2 is in an inverted U shape, wherein the left branch and the right branch of the inverted U shape extend out of the push rod 2, and the end, located outside the placing tube 1, of the push rod 2.

The utility model discloses when using, earlier with the folding coincidence of the support about T type biliary tract drainage tube 4, will fold T type biliary tract drainage tube 4 after again insert and place in the pipe 1, then pinch and place pipe 1, make its pipe diameter reduce, will place after and insert in the drainage mouth pipe 1, put into push head 3 of push rod 2 and place in the pipe 1 to promote T type biliary tract drainage tube 4, until the support about T type biliary tract drainage tube 4 break away from place pipe 1 and expand can.
