Description
Technical field
The present invention relates to technical field of medical equipment more particularly to a kind of choledochoscopes convenient for controlling clamping force.
Background technique
Fiber endoscopy is the development recently as fibre optics and one kind for inventing is mainly used to Diagnosing Biliary Tract Carcinoma disease
New instrument, be one by many optical fibers and the hollow pipe that forms of plastics protection sheath, be observed under a kind of direct-view bile duct,
Common hepatic duct, the special instrument for handling lesion, upwards it can be seen that biliary tract is as deep as III, IV grades of bile duct in liver, visible gallbladder is total downwards
In pipe lower duodenal nipple or even duodenum, and the mucous membrane that can be immediately seen in bile duct whether hyperemia, oedema, erosion
And the shape of cholelith, color, size, number and whether incarceration, can also distinguish clot, bubble, polyp and the roundworm in biliary tract, take
Pathologic finding is made in biopsy, can make the diagnosis of disease of biliary tract, understands position and the property of lesion, if having retained calculus etc..
Laparoscopic surgery is the invasive methods that a new development is got up, it is by making several 0.5-1 lis in patients abdomen
The small notch of rice, each insertion one are called the operation sheath of " trocar ", establish operation path, then with special surgical instrument in electricity
Depending on monitoring the lower completion step same as open surgery, reach same surgical effect.
Fiber endoscopy is essential tool in operation on biliary tract, is usually used in clamping the calculus or lesion group in bile duct
It knits, at this point, it is just particularly significant for the control of pliers clamping power, it is directly related to the therapeutic effect of doctor.Due to biliary tract
Narrow space, the visual field is bad, and difficulty is difficult big when operation, generally requires repeatedly to attempt to succeed.Traditional choledochoscope relies on hand
The strength in portion clamps pliers, in long-time operation meeting so that hand muscle is tired, it is difficult to keep the stability of operation, increase doctor
Raw use difficulty.
Summary of the invention
It is an object of the invention to overcome above-mentioned technical deficiency, a kind of choledochoscope convenient for controlling clamping force, solution are proposed
Certainly choledochoscope use for a long time will lead to operator's hand muscle fatigue in the prior art, it is difficult to keep the technology of operational stability
Problem.
In order to reach above-mentioned technical purpose, the embodiment of the invention provides it is a kind of convenient for control clamping force choledochoscope,
This it is a kind of convenient for control clamping force choledochoscope include:
Grips pincers comprising shell and knob, shell is interior to take object chamber including one, and taking mouth connection is offered on shell
Object chamber is taken, is rotatably connected in the middle part of knob with shell, knob is located at the part for taking object intracavitary and is provided with screw thread.
Adjustable clamp comprising upper tong arm, lower tong arm, upper transmission arm, underdrive arm and connecting rod, upper tong arm and lower tong arm phase
Mutually intersect and be hinged in grips pincers, one end of upper transmission arm and connecting rod are hinged, and the other end and upper tong arm are hinged, underdrive arm
One end is hinged with connecting rod, and the other end and lower tong arm are hinged, and connecting rod is provided with the spiral shell engaged with knob far from one end of upper transmission arm
Line.
Compared with prior art, the invention has the following beneficial effects: of the invention a kind of convenient for control clamping force
Choledochoscope relies on the engaged transmission of knob and connecting rod, drives moving forward and backward for connecting rod, to control the degree of pliers clamping, Yi Sheng
It does not need to be always maintained at firmly state when operation, for a long time using being not easily tied yet, also helps doctor and improve when operating
Precision is controlled, is conducive to improve therapeutic effect.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram convenient for controlling the choledochoscope of clamping force provided by the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.
Referring to Figure 1, Fig. 1 is a kind of structural schematic diagram convenient for controlling the choledochoscope of clamping force provided by the invention.
It is a kind of convenient for control clamping force choledochoscope include: grips pincers, adjustable clamp and casing.
Grips pincers include shell 11 and knob 12.Object chamber is taken including one in shell 11, one is offered on shell 11 and takes object
Mouth connection takes object chamber, and 12 middle part of knob is rotatably connected with shell 11, and knob 12 is located at the part for taking object intracavitary and is provided with screw thread.
Shell 11 is L-type structure, takes object chamber to be set to the long end end of shell 11,11 short end of shell is formed by bending handle, takes convenient for doctor
It takes.
Adjustable clamp includes upper tong arm 21, lower tong arm 22, upper transmission arm 23, underdrive arm 24 and connecting rod 25.Upper tong arm 21
It intersects and is hinged in grips pincers with lower tong arm 22, one end of upper transmission arm 23 and connecting rod 25 are hinged, the other end and upper pincers
Arm 21 is hinged, and one end of underdrive arm 24 and connecting rod 25 are hinged, and the other end and lower tong arm 22 are hinged, and connecting rod 25 is far from upper transmission arm
23 one end is provided with the screw thread engaged with knob 12.Flexible protection pad is set on upper tong arm 21 and the opposite side of lower tong arm 22
Layer, multiple convex blocks or fin are covered on protection pad layer.Upper tong arm 21 and lower tong arm 22 are mostly metal material production, and outside choledochoscope
It is surrounded by plastic layer, after being used for multiple times, jaw is easy folder bad choledochoscope, and protection pad layer is arranged, and can prevent choledochoscope from being pressed from both sides bad.
Choledochoscope is cylinder, and the setting of convex block or fin can increase the contact force of jaw and choledochoscope, thus stronger clamping gallbladder
Road mirror.
One end in grips pincers close to taking mouth is arranged with a casing 3.Casing 3 selects the material with biocompatibility
Production, is preferably titanium alloy in the present embodiment.Casing 3 can avoid tissue and contact with shell 11, to prevent human body
The accidental injury of tissue.
The implementation of the embodiments of the present invention has the following beneficial effects: a kind of biliary tract convenient for controlling clamping force of the invention
Mirror relies on the engaged transmission of knob and connecting rod, drives moving forward and backward for connecting rod, and to control the degree of pliers clamping, doctor is being operated
When do not need to be always maintained at firmly state, for a long time using being also not easily tied, also help doctor improve operation when control
Precision is conducive to improve therapeutic effect.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
