Description
Technical field
The invention belongs to medical instruments field, relate to gallbladder neck tube interimage device, particularly relate to a kind of device for laparoscopic transcystic duct cholangiography.
Background technology
Along with the raising of quality of life, the incidence rate of cholelithiasis increases day by day.Abdominal cavity is just through for the therapeutic regimen of cholelithiasis in the past and carries out gallbladder removal, but when cholelithiasis is less, calculus can be drained in common bile duct by the self-contractility of gallbladder itself.This kind of situation is medically called Secondary cases calculus of bile duct.Once have calculus in bile duct, operation must be opened bile duct and the calculus in it be taken out.Therefore clear and definite bile duct is most important with or without calculus before surgery.Common method in operation is Via bile duct cholangiography.Namely in common bile duct, insert a less angiography tube by cystic duct, determine angiography tube with prevent extravasation of contrast media from then injecting situation that contrast agent just can understand common bile duct with common titanium is clamping, thus determine next step mode of performing the operation.But, there is a lot of problem when needs cholangiography in the past, after angiography tube is inserted biliary tract angiography tube easily from biliary tract slippage cause contrast agent to leak, affect contrasting effects; When the clamping angiography tube determined in biliary tract of titanium, may occur that the obstructed situation about even blocking that the agent of angiography tube interimage is injected occurs; When using titanium clamp pincers binding clip to clamp titanium folder, the easily slippage from titanium clamp pincers two panels binding clip of titanium folder.
Summary of the invention
The invention discloses device for laparoscopic transcystic duct cholangiography.During in order to solve in prior art titanium clamp pincers binding clip gripping titanium folder, the landing from titanium clamp pincers of titanium folder, angiography tube insert angiography tube slippage after in biliary tract and cause contrast agent to flow out, the contrast agent that angiography tube injects biliary tract leaks, and the injection of angiography tube interimage agent is not smooth or the problem of blocking.
For achieving the above object, the technical solution used in the present invention is:
Device for laparoscopic transcystic duct cholangiography, wherein, comprising:
One angiography tube, the head that described angiography tube need insert biliary tract slightly outwards expands;
One folder, described folder the front portion of two jig arm bend laterally, the inner side of described folder is provided with many impressions in length and breadth.
One clamp, be equipped with in the surface that the two panels binding clip of described clamp is mutually corresponding one along described chuck length to strip groove, with accommodating described folder.
Above-mentioned device for laparoscopic transcystic duct cholangiography, wherein, described groove two two end portions is not near described binding clip top and and described binding clip root.
Above-mentioned device for laparoscopic transcystic duct cholangiography, wherein, described angiography tongs binding clip is narrowed to binding clip top width gradually by root, and described clamp binding clip top is camber.
Above-mentioned device for laparoscopic transcystic duct cholangiography, wherein, described angiography tube material is silica gel.
Above-mentioned device for laparoscopic transcystic duct cholangiography, wherein, the material of described folder and clamp is Titanium.
Device for laparoscopic transcystic duct cholangiography of the present invention, have employed following scheme effectively make angiography tube to insert in biliary tract can not slippage, the titanium clamp pincers gripping of titanium double-layered quilt time can not landing and prevent angiography tube from being clamped by titanium time contrast agent not smooth or block.

Detailed description of the invention
The technological means realized to make the present invention, creating feature, reach object and effect is easy to understand, lower combination specifically illustrates, and sets forth the present invention further.
As shown in Figure 1, 2, angiography tube 1 head 2 slightly outwards expands, when angiography tube 1 inserts in biliary tract, its head 2 is applied with tension force to biliary tract inwall in biliary tract, biliary tract inwall hard-pressed bale is rolled in head 2 place of angiography tube 1, angiography tube 1 can not slippage from biliary tract, the material silicon sebific duct of angiography tube 1, its silica gel tube has oil resistivity and elasticity more contributes to anti-skidding in bile duct and bending insertion.The front portion 11 of two jig arm 4 of folder 3 bends laterally, and wherein, two jig arm 4 rear portions 12 of folder 3 are in arc-shaped, and in circular arc portion 5, the diameter of circular arc camber is four to five millimeters.Further, the inner side of folder 3 is provided with many impressions in length and breadth, adds the contact surface of folder 3 and biliary tract wall.
Just can prevent the contrast agent in angiography tube 1 from leaking when folder 3 clamps the biliary tract outside angiography tube by external force, simultaneously when folder 3 is closed by folder, the circular arc portion 5 of its rear portion 12 arc-shaped ensure that the generation that the smoothness that angiography tube injects biliary tract contrast agent more prevents contrast agent from blocking.
As shown in Figure 3, be equipped with in the surface that the two panels binding clip 7 of clamp 6 is mutually corresponding one along chuck length to strip groove 8, with accommodating folder 3.By manually binding clip 7 groove 8 that clamp 6 put into by folder 3 being inserted patient body, and clamp 6 is clipped in the biliary tract outer wall outside angiography tube 1, to prevent leaking of contrast agent, wherein, groove 8 can make folder 3 embed, and prevents folder 3 from inserting slippage in process.
The binding clip 7 of clamp 6 is narrowed gradually by root 9 to binding clip top 10 width as shown in Figure 4, can local among a small circle in carry out work, simultaneously clamp 6 binding clip 7 top 10 is camber, avoids the damage of the 10 pairs of patient's bile duct outer walls in top when folder 3 is inserted by clamp 6.Further, pressing from both sides 3 with the material of clamp 6 is Titanium.
In this specific embodiment, the angiography tube 1 of outwards expansion 2 is omited until in bile duct by gallbladder neck tube otch insertion head, folder 3 is put in clamp 6, by clamp 6, folder 3 is inserted the cystic duct place of patient, and the bile duct outer wall making folder 3 be clipped in place angiography tube 1 makes bile duct inwall be close to angiography tube 1, just can inject contrast agent after completing in angiography tube radiography is carried out to patient's biliary tract.
In sum, device for laparoscopic transcystic duct cholangiography of the present invention, effectively make angiography tube to insert in biliary tract can not slippage, the titanium clamp pincers gripping of titanium double-layered quilt time can not landing and prevent angiography tube from being clamped by titanium time contrast agent not smooth or blocking, its structure is simple, and it is more convenient that radiography operates.
Above specific embodiments of the invention are described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, the equipment wherein do not described in detail to the greatest extent and structure are construed as to be implemented with the common mode in this area; Those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present invention.
