Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, the nail supporting base assembly particularly on a kind of anastomat.
Background technology
Surgeon is after a part of carrying out the tubular tissue of the human body such as intestinal, esophagus carries out excision, and when the tubular tissue stayed be connected, its usual way is connected by anastomat with special anastomosis staple.Digestive tract stapler mainly comprises pushing device and is connected to the nail supporting base assembly on pushing device, operator is after the preparation carrying out percussion anastomat, during cocking percussion anastomat, pushing device is then made to be pushed in the nail supporting base of nail supporting base assembly by two stoma sites that identical pin docks through the needs of the tubular tissue of human body, two of identical pin terminations are curved inwardly, and two of tubular tissue stoma sites are linked together.The nail supporting base of the nail supporting base assembly of anastomat with the connection between locator card reed pipe for being fixedly connected with, namely nail supporting base is vertically fixed on the end of locator card reed pipe, nail supporting base relative to locator card reed pipe and be connected with locator card reed pipe comprise anastomat in interior pushing device front portion cannot change position, and due to the complex structure of tissue, and nail supporting base and locator card reed pipe and pushing device front portion are when keeping upright position, because nail supporting base has certain surface area, when tube chamber is narrow and small, nail supporting base cannot arrive desired location preferably, nail supporting base enter organize time usually can stop by tissue.
Also the rotating prior art of some nail supporting bases is had in the market, Chinese patent literature CN202740062U discloses a kind of mounting structure of resist-nailed seat of anastomat, comprise nail supporting base and push rod (being equivalent to locator card reed pipe), nail supporting base is rotatably connected through locking device and push rod, the mounting structure of this nail supporting base be arranged on anastomat with it time, nail supporting base and push rod keep upright position, still there is the shortcoming that cannot arrive lesions position preferably entering human body, its structural design is after anastomat arrives desired location percussion, because its locking device is along with the release of percussion, nail supporting base can rotate after identical percussion, thus nail supporting base can exit preferably from human body, thus similar above-mentioned rotating nail supporting base is all to exit human body preferably after anastomat percussion, the problem of more difficult arrival assigned address is still there is when nail supporting base enters human body before firing.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of, movable nail supporting base assembly of more easily arriving human body assigned address less with the contact surface of tissue.
The technical scheme realizing this utility model object is to provide a kind of movable nail supporting base assembly, comprises nail supporting base, locator card reed pipe, seat cap connecting axle, jump ring pipe connector, spring compression screw, spring, hoodle and connecting pin.
Nail supporting base has the first central stepped bore.The bottom of seat cap connecting axle is tabular, and the bottom of seat cap connecting axle is provided with the first through pin-and-hole of front and back, and the overall axes normal of the axis of the first pin-and-hole and seat cap connecting axle.The lower surface central authorities of the bottom of seat cap connecting axle are provided with the first ball race of a spherical crown shape, lower surface lateral symmetry centered by the first ball race of the bottom of seat cap connecting axle is provided with the second ball race, the axis of the first ball race, 2 the second ball races all with the axes intersect of the first pin-and-hole in a bit.The epimere position of jump ring pipe connector is the hinge point matched with the bottom of seat cap connecting axle, the position, stage casing of jump ring pipe connector and hypomere position all have the second central stepped bore of up/down perforation in column, second central stepped bore is in becoming large syllogic shoulder hole successively from the top down, and the hypomere position of the second central stepped bore is provided with female thread.The lower end head of spring compression screw is provided with the external screw thread corresponding with the female thread at the hypomere position of the second central stepped bore of jump ring pipe connector.The diameter of the diameter in the diameter of hoodle, the upper sector hole portion of the second central stepped bore and the first ball race, the second ball race is all corresponding.The internal diameter of spring is less than the diameter of hoodle.
The axis of any one the second ball race of seat cap connecting axle and the angle of the axis of the first ball race are α.
Seat cap connecting axle is fixed on nail supporting base by its top and middle part coaxial line, and is positioned at the first central stepped bore of nail supporting base.It is hinged that seat cap connecting axle passes through connecting pin by its lower board unit and jump ring pipe connector.The hypomere position of spring compression screw is combined in by its external thread rotary in the hypomere position of the second central stepped bore of jump ring pipe connector, and spring coaxial line is enclosed within the epimere polished rod position of spring compression screw.Hoodle is arranged in the upper sector hole portion of the second central stepped bore of jump ring pipe connector, and the upper-end part of driving of hoodle embeds in the first ball race or any one the second ball race, and the lower end part of hoodle and spring contact Compress Spring thus hoodle are by spring institute resiliency supported.Jump ring pipe connector to be inserted in locator card reed pipe by its hypomere position and just connects with locator card reed pipe.
Further, above-mentioned one activity nail supporting base assembly also comprises knife washer.First central stepped bore of nail supporting base is the hole portion that large in two ends, middle little and lower-side hole section is greater than upper end hole section.Knife washer coaxial line to be fixed on nail supporting base and to be positioned at the lower-side hole section of the central stepped bore of nail supporting base.Top and the global shape at middle part of seat cap connecting axle match with the first central stepped bore of nail supporting base, and the entire length at top and middle part is corresponding with the entire length of the first central stepped bore.
Further, the epimere position of jump ring pipe connector is made up of two pieces, front and back connecting plate thus upper-end part of driving opening upwards, left and right are through, and two pieces, the front and back connecting plate at the epimere position of jump ring pipe connector is provided with second pin-and-hole corresponding with the first pin-and-hole of seat cap connecting axle.It is hinged by being arranged on connecting pin and jump ring pipe connector in the first pin-and-hole and the second pin-and-hole seat cap connecting axle is inserted the epimere position of jump ring pipe connector by its lower board unit after.
Further, the external diameter at the position, stage casing of jump ring pipe connector is greater than the external diameter at hypomere position.The diameter of the center through hole of locator card reed pipe is corresponding with the external diameter at the hypomere position of jump ring pipe connector, and the external diameter of locator card reed pipe is corresponding with the external diameter at the position, stage casing of jump ring pipe connector.
