Abstract
The utility model relates to a distance-changing threaded rod of a disposable guide type anorectal hemorrhoid anastomat, wherein the distance-changing threaded rod is used in cooperation with the disposable guide type anorectal hemorrhoid anastomat. The distance-changing threaded rod of the disposable guide type anorectal hemorrhoid anastomat is composed of a distance gradual changing thread section and a non-thread section. The distance gradual changing thread section is arranged at the front end of the non-thread section and provided with single-head distance gradual changing threads, a connecting pipe mounting hole is arranged in the rear end of the non-thread section, and a movable block fixing threaded hole is arranged between the distance gradual changing thread section and the non-thread section. The distance-changing threaded rod is a thickened threaded rod, and the diameter of the distance-changing threaded rod is 9-14mm. When the distance-changing threaded rod is adjusted by a doctor during an operation, the distance-changing threaded rod can be positioned more quickly and accurately through the distance gradual changing threads; because only a section of the threads exists, hand feeling is good when the threaded rod is adjusted, strength of the threaded rod is improved because the diameter of the threaded rod is thickened, fracture of the threaded rod due to overexertion during the operation is avoided, it is guaranteed that the operation is smoothly performed, and operation risks are lowered.
Description
Technical field
The utility model relates to a kind of guided disposable type anorectal hemorrhoid anastomat Variable pitch screw, be applicable to support the use with guided disposable type anorectal hemorrhoid anastomat.
Background technology
In the devices such as medical apparatus and instruments, need to use a kind of guided disposable type anorectal hemorrhoid anastomat.Its defect is: pitch is little, the number of turns is many, when regulating, speed is slow, because the screw thread by 3 sections of different pitch forms, when adjusting, feel has some setbacks, because of Variable pitch screw diameter thinner, run into that doctor overexerts in operation process and the risk that easily causes screw rod fracture, can not guarantee that operation carries out smoothly, increase operation risk.
Summary of the invention
This utility model object is to provide a kind of guided disposable type anorectal hemorrhoid anastomat Variable pitch screw for above-mentioned weak point, Variable pitch screw is that overstriking screw diameter, thread segment are designed to gradually gaining twist, when doctor's operative adjustment gradually gaining twist can be sooner, location more accurately, owing to only having one section of screw thread, good hand touch during adjustment, overstriking screw diameter has improved screw strength, avoid doctor in operation process, because overexerting, to cause screw rod fracture, guarantee to perform the operation and carry out smoothly, reduce operation risk.
Guided disposable type anorectal hemorrhoid anastomat Variable pitch screw is to take following technical scheme to realize:
Guided disposable type anorectal hemorrhoid anastomat Variable pitch screw is comprised of apart from thread segment and non-threaded section gradual change, at non-threaded section of front end, be provided with gradual change apart from thread segment, gradual change is provided with gradually gaining twist of single head apart from thread segment, non-threaded section of rear end, be provided with connection tube installing hole, in gradual change, apart between thread segment and non-threaded section, be provided with movable block fixing threaded hole.
Described Variable pitch screw is overstriking screw rod, and diameter is 9～14mm.
When guided disposable type anorectal hemorrhoid anastomat Variable pitch screw and guided disposable type anorectal hemorrhoid anastomat support the use, adjustable pipe is sleeved on gradual change apart from thread segment, fore-set is installed in adjustable pipe to be coordinated apart from thread groove with gradual change, movable block is fixed on Variable pitch screw middle part by movable block fixing threaded hole, connection tube is connected with non-threaded section of rear end of Variable pitch screw by connection tube installing hole, rotating adjustable pipe moves forward and backward Variable pitch screw by fore-set, be used for driving movable block and connection tube to move forward and backward, can sooner, more precisely carry out location of operation.
This utility model guided disposable type anorectal hemorrhoid anastomat Variable pitch screw is reasonable in design, Variable pitch screw is set to overstriking screw diameter, thread segment is designed to gradually gaining twist, when doctor's operative adjustment gradually gaining twist can be sooner, location more accurately, owing to only having one section of screw thread, good hand touch during adjustment, overstriking screw diameter has improved screw strength, avoids doctor in operation process, because overexerting, to cause screw rod fracture, guarantee to perform the operation and carry out smoothly, reduce operation risk.Guided disposable type anorectal hemorrhoid anastomat Variable pitch screw, is applicable to support the use with guided disposable type anorectal hemorrhoid anastomat.
Accompanying drawing explanation
Below with reference to accompanying drawing, the utility model is described in further detail:
Fig. 1 is guided disposable type anorectal hemorrhoid anastomat Variable pitch screw structure and using state schematic diagram.
The specific embodiment
With reference to accompanying drawing 1, guided disposable type anorectal hemorrhoid anastomat Variable pitch screw is comprised of apart from thread segment 2 and non-threaded section 1 gradual change, at non-threaded section of 1 front end, be provided with gradual change apart from thread segment 2, gradual change is provided with gradually gaining twist of single head apart from thread segment 2, non-threaded section of 1 rear end, be provided with connection tube installing hole 3, in gradual change, apart between thread segment 2 and non-threaded section 1, be provided with movable block fixing threaded hole 4.
Described Variable pitch screw is overstriking screw rod, and diameter is 9～14mm.
When disposable importing supports the use to type anorectal hemorrhoid anastomat Variable pitch screw and guided disposable type anorectal hemorrhoid anastomat, adjustable pipe 8 is sleeved on gradual change apart from thread segment 1, fore-set 9 is installed in adjustable pipe 8 to be coordinated apart from thread groove 7 with gradual change, movable block 5 is by screw 4, movable block fixing threaded hole is fixed on Variable pitch screw middle part, connection tube 6 is connected with non-threaded section of 1 rear end of Variable pitch screw by connection tube installing hole 3, rotating adjustable pipe 8 moves forward and backward Variable pitch screw by fore-set 9, be used for driving movable block 5 and connection tube 6 to move forward and backward, can be faster, more precisely carry out location of operation.
