Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of hepatology medical apparatus and instruments, is specifically related to a kind of cholangiography pincers.
Background technology
In body in laparoscopic procedures, once find gallbladder focus in body, need operative treatment, performing the operation in treatment journey, biliary tract needs to be separated and shaping, in the checking process of CT and B ultrasonic, can strengthen definition.Prior art carries out biliary tract shaping with general operating forceps, and its defect uses general operating forceps easily to damage biliary tract.Also special cholangiography pincers are had at present, its concrete structure is comprise the handle be made up of the pull end be rotatedly connected and rear handle, outer tube is rotatedly connected by wheel set assembly and pull end, at the top of outer tube, caliper is set, be provided with the push-rod assembly for controlling caliper switch within the outer tube, the tail end of push-rod assembly is connected with rear handle, and caliper comprises and being rotatedly connected and mutually corresponding upper grip head and lower pliers head, and the root of upper grip head is connected with the head end of push-rod assembly respectively with the root of lower pliers head.Still there is following shortcoming in this kind of structure, one is clear dose still needs to enter biliary system by other pipelines, and definition can not meet desirable surgical effect; Two be the upper grip head of caliper and lower pliers head is straight plate structure, and due to biliary tract more crisp, clamp with the caliper of said structure, easily cause biliary duct injury, thus cause the injury to patient.
Utility model content
According to above the deficiencies in the prior art, this utility model provides a kind of cholangiography to clamp, and both can not damage biliary tract, can have again the good advantage of contrasting effects.
A kind of cholangiography pincers described in the utility model, comprise the handle be made up of the pull end be rotatedly connected and rear handle, outer tube is rotatedly connected by wheel set assembly and pull end, at the top of outer tube, caliper is set, be provided with the push-rod assembly for controlling caliper switch within the outer tube, the tail end of push-rod assembly is connected with rear handle, and caliper comprises and being rotatedly connected and mutually corresponding upper grip head and lower pliers head, and the root of upper grip head is connected with the head end of push-rod assembly respectively with the root of lower pliers head; It is characterized in that: be also provided with needle tubing in outer tube, needle tubing one end is piercing in the front end of caliper, and the other end is piercing in outer tube and is connected with needle tubing interface; Upper grip head is that leading portion and rear are horizontal structure, stage casing is the arcuate structure of outwardly convex, and lower pliers head and upper grip head design for symmetrical expression, and the inner surface of upper grip head and lower pliers head is provided with intermeshing latch.
Wherein, preferred version is as follows:
Latch is round end tooth, therefore can not be caused because of the damage of crown bleeding by the biliary tract tissue surface clamped.
In this utility model, needle tubing is movably arranged in outer tube, needle tubing can be extracted or insert within the outer tube, in cholangiography operation process, clear liquid is injected needle tubing interface through needle tubing, enter the cholangiography position in body, the best sharpness that X-ray film making, B ultrasonic and CT treatment check can be increased.The cavity of upper grip head and lower pliers head stage casing composition can hold larger biliary tract tissue, in operation application, convenient biliary tract organ is carried out systematic position, shaping and dredging, makes biliary tract organ can not arbitrarily wavy and damage.In addition, the cavity of upper grip head and lower pliers head stage casing composition can also serve as the effect in radiography hole.
The beneficial effect that this utility model has is: reasonable in design, and cleanout fluid directly injects in needle tubing the cholangiography position entered in body, and contrasting effects is good, and caliper structure redesigns and makes safety easy to use of performing the operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, handle 2, outer tube 3, wheel set assembly 4, upper grip head 5, lower pliers head 6, needle tubing 7, needle tubing interface 8, latch.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, this utility model is described further.
Embodiment 1:
As shown in Figure 1, a kind of cholangiography pincers, comprise the handle 1 be made up of the pull end be rotatedly connected and rear handle, outer tube 2 is rotatedly connected by wheel set assembly 3 and pull end, arranging caliper at the top of outer tube 2, being provided with the push-rod assembly for controlling caliper switch in outer tube 2, the tail end of push-rod assembly is connected with rear handle, caliper comprises and being rotatedly connected and mutually corresponding upper grip head 4 and lower pliers head 5, and the root of upper grip head 4 is connected with the head end of push-rod assembly respectively with the root of lower pliers head 5; Also be provided with needle tubing 6 in outer tube 2, needle tubing 6 one end is piercing in the front end of caliper, and the other end is piercing in outer 2 pipes and is connected with needle tubing interface 7; Upper grip head 4 is that leading portion and rear are horizontal structure, stage casing is the arcuate structure of outwardly convex, and lower pliers head 5 is with upper grip head for symmetrical expression designs, and the inner surface of upper grip head 4 and lower pliers head 5 is provided with intermeshing latch 8.
Latch 8 is round end tooth, therefore can not be caused because of the damage of crown bleeding by the biliary tract tissue surface clamped.
In this device, needle tubing 6 is movably arranged in outer tube 2, needle tubing 6 can be extracted or be inserted in outer tube 2, in cholangiography operation process, clear liquid is injected needle tubing interface 7 through needle tubing 6, enter the cholangiography position in body, the best sharpness that X-ray film making, B ultrasonic and CT treatment check can be increased.The cavity of upper grip head 4 and lower pliers head 5 stage casing composition can hold larger biliary tract tissue, in operation application, convenient biliary tract organ is carried out systematic position, shaping and dredging, makes biliary tract organ can not arbitrarily wavy and damage.In addition, the cavity of upper grip head 4 and lower pliers head 5 stage casing composition can also serve as the effect in radiography hole.
