Description
technical field:
The present invention relates to a kind of fiber endoscopy pincers, belong to medical instruments field.
background technology:
Fiber endoscopy is a kind of new apparatus being mainly used to Diagnosing Biliary Tract Carcinoma disease invented along with fiberoptic development in recent years, it is a hollow pipe protecting sheath to form by many optical fibers and plastics, being that a kind of direct-view is lower observes gallbladder pipe, common hepatic duct, the special apparatus of process pathological changes, upwards can see that in liver, biliary tract reaches III deeply, the gallbladder pipe of IV level, common bile duct lower duodenal nipple can be seen downwards, even in duodenum, and directly can see that whether the mucosa in bile duct is congested, edema, the shape of erosion and cholelithiasis, color, size, number and whether incarceration, also can distinguish the clot in biliary tract, bubble, polyp and ascarid, get biopsy and make pathologic finding, the diagnosis of biliary tract can be done, understand position and the character of pathological changes, whether there is retained calculus etc.
Laparoscopic surgery is the invasive methods that a new development is got up, it is the minimal incision * by doing several 0.5-1 centimetre in patients abdomen, each insertion one is called the operation sheath of " trocar ", set up operation path, under television monitoring, complete the step same with open surgery by special operating theater instruments again, reach same surgical effect.
Fiber endoscopy is requisite instrument in operation on biliary tract, under peritoneoscope, operation is difficult to fixing, must be fixed and could enter biliary tract smoothly and operate with pliers, and in existing apparatus, there is no special fiber endoscopy pincers, generally all carry out capturing and fixing with nipper in operation, and the binding clip of nipper is metal casts, there is sharp groove, the protection sheath of fiber endoscopy is plastic material, be very easy to damaged after capturing several times, once damaged, optical fiber is easily sterilized solution corrosion damage, and keep in repair plastics sheath not only time-consuming (January) but also somewhat expensive (20,000 yuan), must repeatedly keep in repair every year, use cost is high.In order to the probability that the plastics epitheca reducing choledochoscope is scratched by sharp nipper, in use, doctor generally can on the cover of nipper binding clip position one deck plastic flexible pipe, the damage that can reduce plastics epitheca during crawl like this, but also exist and capture shakiness, fixing defect loosely.
summary of the invention:
For the defect existed in above-mentioned prior art, the object of the present invention is to provide a kind of fiber endoscopy pincers be exclusively used under peritoneoscope, it captures convenient, be easy to fixing, and it is minimum to the damage of choledochoscope epitheca, decrease daily maintenance cost and use cost, effectively extend the service life of fiber endoscopy.
To achieve these goals, the technical solution used in the present invention is:
A kind of fiber endoscopy pincers, comprise fixed handle and flexible handle, fixed handle and flexible handle are rotationally connected, connecting rod is connected with flexible handle, and binding clip is connected with connecting rod, it is characterized in that: described binding clip comprises tong arm and lower tong arm, the inner surface correspondence of upper tong arm, lower tong arm is provided with arcuate groove, when upper and lower tong arm is in closure state, the middle part of binding clip forms a through hole, and the vertical diameter of through hole is arranged on 0.3cm ~ 0.60cm.
The further setting of the present invention is:
Described binding clip entirety is cylindrical shape, and binding clip diameter is 0.4 ~ 0.9cm, and binding clip length is 1.5 ~ 2.5cm.
Preferably, described binding clip diameter is 0.5cm, and binding clip length is 2cm, and the vertical diameter of through hole is 0.36cm.
Line style tooth bar established by the arcuate groove of upper tong arm, lower tong arm, and the direction of tooth bar is the length direction of caliper.
The arcuate groove of upper tong arm, lower tong arm arranges embedded liner, liner arranges protuberant particles or cross cut.The material of described liner is timber or rubber.At the arc-shaped groove inner surface of upper tong arm, lower tong arm, frictional layer is set.Not only increase friction, easily fix, and sheath do not protected by easy damaged choledochoscope plastics.
Described upper tong arm, one end of lower tong arm are free end, the other end intersects mutually, hinged by connecting pin one at infall, the end of upper tong arm, lower tong arm is hinged with one end of the first brace, the second brace respectively, and the first brace, the second brace other end are connected with connecting rod by connecting pin two.
Also comprise connecting rod cover and clamp seat, connecting rod is contained in connecting rod cover, and one end and the fixed handle of connecting rod cover are rotationally connected, and can rotate relative to fixed handle, the other end of connecting rod cover is connected with clamp seat, and the infall of upper tong arm and lower tong arm is connected on clamp seat by connecting pin.
Arrange runner at the handle end of connecting rod cover, described runner is sleeved on connecting rod by rotaring wheeling sleeve and puts.
Rotaring wheeling sleeve is provided with the bath joint overlapping intracavity inter-connection with connecting rod, fixed handle is provided with coagulation interface.
Beneficial effect of the present invention is:
1, of the present invention by being provided with arcuate groove in the inner surface correspondence of upper tong arm, lower tong arm, make in the middle part of binding clip, to form the little through hole in two broad in the middle, and suitable through-hole diameter is set, choledochoscope is limited in the middle part of through hole, because the vertical diameter of through hole is suitable with choledochoscope diameter, exerting oneself to choledochoscope during clamping, dynamics is less just can be clamped, and can not move left and right because two of through hole is little, and clamping is firm.
2, the length by rationally arranging binding clip of the present invention makes binding clip under peritoneoscope, open less angle and just can realize choledochoscope clamping, long or the upper and lower tong arm of binding clip opens too general idea damage tissue around and blood vessel, rational binding clip diameter can ensure that upper and lower tong arm has certain thickness, not easily lose during use, the rational clamping face formed, chucking power is better.
3, the present invention arranges frictional layer at the inner surface of binding clip, originally sharp horizontal pointed tooth is replaced to the thin tooth of longitudinal line style or elastic liner, not only increase the frictional force of clamping face, and longitudinal direction tooth bar restriction choledochoscope in through-holes movable, fine and closely woven thin tooth and elastic insert damage minimum to the plastics epitheca of fiber endoscopy, found through experiments, use general nipper to capture and fixing choledochoscope, its plastics epitheca is employing tens times to twenties times just breakages, but use choledochoscope of the present invention to clamp to carry out capturing and fixing, choledochoscope epitheca employ up to a hundred time after, only occur necessarily grabbing print on device surface, not there is disrepair phenomenon, greatly reduce daily maintenance cost, the service life of effective prolongation fiber endoscopy.
