Background technique

Cholecystolithiasis merges patients with choledocholith, and Via bile duct bile duct sets pipe external drainage and is conducive to laparoscopic cholecystectomy Postoperative endoscopic stone extraction technique；Common bile detects Via bile duct bile duct in primary suture patient's art and sets pipe external drainage, during setting pipe It can intuitively check the effect of Primary suture, further inlying catheter external drainage is a kind of biliary extra-drainage of simplification Operation remains a postoperative decompression, checks, the channel for the treatment of, effectively prevents Primary suture bile leakage after operation, expand The indication of Primary suture.It there is no the device and equipment of the fixation Via bile duct T-type drainage tube of specificity at present.

Therefore solve the problems, such as therefore this kind is particularly important, the above problem is drawn to fixed Via bile duct bile duct It should pay attention to and solve the problems, such as during the device design and use of flow tube.

Utility model content

In view of the above problems, the utility model provides that a kind of structure is simple, ensures that sewing process is safer and consolidates Determine Via bile duct biliary drainage pipe device.

The technical solution of the utility model is: a kind of fixed Via bile duct biliary drainage pipe device, including elastica, The elastica includes elastic main line and elasticity time line, and the elasticity time line is wrapped in the elastic main line surface, the elasticity The both ends of line are equipped with attachment base, and sub-buckle and female thread are respectively equipped on the attachment base and is attached the both ends of elastica.

Further improvement of the utility model is: the attachment base bottom is equipped with threading hole and stay thimble, the elasticity Main line penetrates in the threading hole and connects the stay thimble and is fixed.

Further improvement of the utility model is: being uniformly provided with several protrusions on the elasticity time line.

Further improvement of the utility model is: the sub-buckle and female thread are connected in the form of hasp or lock It connects.

Further improvement of the utility model is: the elasticity main line, elasticity time line, attachment base, sub-buckle and female thread Biodegradable material is all made of to be made.

The utility model provides a kind of fixed Via bile duct biliary drainage pipe device, by elastic main line surface wrap One layer of elasticity time line, enhances the firmness of elastica, and protrusion is arranged on elastic line, enhances frictional force, is not easy it It slides, and produces corresponding stress between tissue, and use the form of snap fastener, can easily carry out the both ends of line Closure reduces the operation difficulty and working strength of medical worker, and its whole all structure is by Biodegradable material system At after being implanted into the patient, degradation being gradually crushed after a period of time, finally by absorption of human body, thus will not be Patient's body forms physics residual.

It is simple to operation, conveniently, safely the beneficial effects of the utility model are: its structure is simple, in closing course not Lateral displacement easily occurs, it is not only solid and reliable, pipe week leakage is avoided, it, can be automatic once conduit is pulled out because it is rich in elastic force It is closed cystic duct, the generation for preventing gallbladder from leaking pulls out drainage tube as early as possible, shortens operation and the recovery time of patient, by It is made in using Biodegradable material, is closed and does not all allow easy fracture when disassembling, there is very wide application prospect.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Wherein: 1- elasticity main line, 2- elasticity time line, 3- attachment base, 4- sub-buckle, 5- female thread, 6- stay thimble, 7- protrusion.

Specific embodiment

In order to deepen the understanding to the utility model, the utility model is done further below in conjunction with drawings and examples Detailed description, the embodiment are only used for explaining the utility model, do not constitute and limit to the protection scope of the utility model.

Such as figure, the present embodiment provides a kind of fixed Via bile duct biliary drainage pipe device, including elastica, the elasticas Including elastic main line 1 and elasticity time line 2, the elasticity time line 2 is wrapped in 1 surface of the elastic main line, and the two of the elastica End is equipped with attachment base 3, and sub-buckle 4 is respectively equipped on the attachment base 3 and the both ends of elastica are attached by female thread 5, described 3 bottom of attachment base is equipped with threading hole and stay thimble 6, and the elasticity main line 1 penetrates in the threading hole and connects the stay thimble 6 It is fixed, is uniformly provided with several raised 7 on the elasticity time line 2, the sub-buckle 4 and female thread 5 are carried out in the form of hasp Connection.Its composed structure of the device is all made of Biodegradable material and is made.

The present embodiment provides a kind of fixed Via bile duct biliary drainage pipe devices, by elastic 1 surface wrap of main line One layer of elasticity time line 2, enhances the firmness of elastica, and the setting protrusion 7 on elastic line 2 enhances frictional force, makes it not Easily slide, and produce corresponding stress between tissue, and use the form of snap fastener, can easily by the both ends of line into Row closure reduces the operation difficulty and working strength of medical worker, and its whole all structure is by Biodegradable material It is made, after being implanted into the patient, degradation can be gradually crushed after a period of time, finally by absorption of human body, thus will not Physics residual is formed in patient's body.

The beneficial effect of the present embodiment is: its structure is simple, simple to operation, conveniently, safely, is not easy in closing course Lateral displacement occurs, it is not only solid and reliable, pipe week leakage is avoided, because it is rich in elastic force, once conduit is pulled out, can be closed automatically Cystic duct is closed, the generation for preventing gallbladder from leaking pulls out drainage tube as early as possible, shortens operation and the recovery time of patient, due to It is made of Biodegradable material, is closed and does not all allow easy fracture when disassembling, there is very wide application prospect.
