Description
Technical field
This utility model belongs to Genneral Surgery field, relates to a kind of hepatobiliary surgery drag hook component.
Background technology
Genneral Surgery's acute hepatic failure mainly studied caused by hepatocarcinoma, hepatic calculus, posthepatitic cirrhosis and hepatitis gravis is the major disease of serious threat compatriots health.Calculus in the bile duct that hepatic calculus means more than common hepatic duct bifurcated.16.1% is accounted in the routine cholelithiasis investigation in the whole nation 11342.Hepatic calculus can exist with Narrow bile duct in liver.According to the analysis of the whole nation 4197 routine hepatic calculus operative treatment cases, the incidence rate average out to 24.28% of Narrow bile duct in liver, superlatively district on average can reach 41.94%.The case of second time operation, more than 40% with Narrow bile duct in liver, and narrow incidence rate is directly proportional to again performing the operation.Be mostly the mixed pigment stone containing more amount calcium bilirubinate, pathogenic factor may with biliary tract infection, bile retention and biliary tract parasite relevant.At present, due to B ultrasonic, the PTC of PTC, ERCP, CT and ultrasound guidance extensively carries out and universal, to make in liver hepatolith and narrowly to be made a definite diagnosis faster, and can obtain the overall picture display of iconography gallbladder system pathological change.But the therapeutic effect still satisfaction not of hepatic calculus at present, after operative treatment, residual calculus rate is still up to 30.4%,
In the disease that Genneral Surgery is common, usually need to perform the operation to region of interest, and when performing the operation, need region of interest to pull out, need in the process to use surgery tractor, and existing surgery tractor needs paraprofessional personnel to assist aside, trouble very, and the drag hook of more existing semi-automation is in use also inconvenient.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provide a kind of hepatobiliary surgery drag hook component, this hepatobiliary surgery drag hook component smart structural design, easy to use, solve existing drag hook component structural design unreasonable, use trouble, the problem such as waste time and energy.
The purpose of this utility model realizes by following technical proposal: a kind of hepatobiliary surgery drag hook component, it is characterized in that: described drag hook component comprises a pair and arranges and the matrix be rectangle in opposition, described matrix have several screwed holes one, described matrix slidably connects the mounting blocks be rectangle, the side of described mounting blocks is electromagnetism portion, in described electromagnetism portion, there is electromagnetic block, the center of described mounting blocks has the guide groove running through described mounting blocks both sides, the tension block be rectangle is slidably connected in described guide groove, described tension block is made up of metal material, the upper end of described tension block has several coupler bodies, described coupler body comprises pars contractilis and hook portion, the lower end of described pars contractilis is hinged in described tension block, the upper end thereof of described pars contractilis has described hook portion, one end of described hook portion is articulated with described pars contractilis, the other end of described hook portion has curved gib head, described stay cord block upper center place has protrusion and cylindrical shadoof.
The roughly use procedure of this drag hook component is as follows: matrix is arranged on patient both sides by screwed hole one, according to the distance between shape adjustment two mounting blocks of patient, convenience very, then gib head is hooked in operative site both sides, now electromagnetic block is not energized, then tension block is pressed downwards, the moving up and down of restrained stretching block according to demand, coupler body freely-movable is enable by the articulated structure at two places and pars contractilis, smart structural design, then electromagnetic block is energized, the side of electromagnetic block absorption tension block, tension block is made to be fixed on corresponding position, the design of this modular construction is ingenious, very convenient, the both hands of nursing staff are liberated.
In above-mentioned a kind of hepatobiliary surgery drag hook component, described matrix center has the trolley shoe of protrusion, has corresponding chute bottom described mounting blocks.
Realize being slidably connected by trolley shoe and chute, convenient and practical.
In above-mentioned a kind of hepatobiliary surgery drag hook component, described trolley shoe has several screwed holes two, described mounting blocks upper end has corresponding screwed hole three.
After mounting blocks position is fixing, realizes the fixing of mounting blocks by screwed hole two and screwed hole three, prevent external force from mounting blocks is offset.
In above-mentioned a kind of hepatobiliary surgery drag hook component, the upper end outer wall of described shadoof has some anti-skidding burrs.
Restrained stretching block realizes by controlling shadoof, and anti-skidding burr makes comfort strong, handled easily.
Compared with prior art, this hepatobiliary surgery drag hook component has the following advantages:
1, this hepatobiliary surgery drag hook component smart structural design, easy to use.
2, this hepatobiliary surgery drag hook component enables coupler body freely-movable, smart structural design by the articulated structure at two places and pars contractilis, achieves the stretching to each different operative site of health.
3, this hepatobiliary surgery drag hook component restrained stretching block realizes by controlling shadoof, convenience very.
