Abstract
The invention relates to a pole clamping device for a surgical incision expander. The pole clamping device comprises a clamping base, a clamping plate and a clamping adjustment rod, wherein a downward fixed clamping jaw is arranged on one side of the clamping base; the middle part of the clamping plate is movably hinged to the lower part of the clamping base; a movable clamping jaw is arranged on one side of the clamping plate and forms a clamping chamber together with the corresponding fixed clamping jaw; the other side of the clamping plate is in threaded spiral connection with and tightly supports the clamping adjustment rod of the clamping base; more than one up-and-down through pole mounting hole is formed in the clamping base. According to the pole clamping device, the fixed and movable clamping jaws of the clamping base and the clamping plate are in adjustable clamping connection with an operating table, and an expander pole is spirally penetrated in the clamping base, so as to realize the adjustable adaptation fixing of the pole on the side edge of the operating table; the pole clamping device is simple in structure, high in adaptability, stable and firm in fixing, and high in hygienic safety performance.
Description
Technical field
The present invention relates to a kind of clamping device, is a kind of operative incision dilator vertical rod clamping device specifically.
Background technology
In surgical operation, usually need to strut otch, to inside of human body operation technique.Traditional otch adopts distraction forcep to keep softened state by manual operation, there is effort, struts the deficiencies such as de-stabilising effect otch.Existing dilator adopts vertical rod to be vertically fixed on operating-table periphery and realizes lasting otch and strut, and for avoiding dilator to support unstable damage otch, such dilator requires higher to the fixing-stable performance between vertical rod and operating-table.
Summary of the invention
In order to meet the high request of vertical rod fixing-stable performance, the invention provides a kind of structure simple, the operative incision dilator vertical rod clamping device high with operating-table suitability, fixing-stable is firm.
The technical solution used in the present invention is: a kind of operative incision dilator vertical rod clamping device, comprise clamping seats, clamping plate and clamping adjusting rod, clamping seats side be provided with down fix to clamp pawl, the middle part of clamping plate is movably hinged in clamping seats bottom, clamping plate side is provided with correspondence and fixes to clamp the floating clamping jaws that claw type becomes clamping chamber, clamping plate opposite side screw thread spins and holds out against the clamping adjusting rod of clamping seats, and clamping seats is provided with the vertical rod installing hole of more than one up/down perforation.
Further, described vertical rod installing hole is for coordinating the externally threaded screwed hole of vertical rod.
Further, described clamping adjusting rod band is by flexible handle.
Further, torsion spring is provided with between described clamping plate and clamping seats.
Again further, described torsion spring is connected to the jointed shaft of clamping plate and clamping seats.
Adopt above technical scheme, the invention has the beneficial effects as follows:
1, under clamping plate elasticity is movably articulated in clamping seats, regulate flexible handle to rotate clamping adjusting rod to regulate clamping adjusting rod spiral on clamping seats to advance to hold out against clamping seats or retrogressing to unclamp to hold out against clamping seats, when the advance of clamping adjusting rod holds out against clamping seats, drive clamping plate opposite side away from clamping seats, the floating clamping jaws of clamping plate side rotates towards fixing to clamp pawl, with the clamping chamber fixing to clamp claw type and become, clamping intracavity clamping operating-table side or frame realize the fixing of clamping seats, and fixing-stable is firm; When the retrogressing of clamping adjusting rod is unclamped and held out against clamping seats, drive clamping plate opposite side near clamping seats, the floating clamping jaws of clamping plate side oppositely fixes to clamp pawl and rotates, and throws off and the clamping fixing to clamp pawl, unclamps the clamping of clamping device, simple operation; Torsion spring between clamping seats and clamping plate can improve the speed of unclamping clamping further, improves operating characteristics.The fungi-proofing cloth clamping that surgical patients can also cover by clamping intracavity simultaneously, improves medical safety performance.
2, clamping seats is arranged vertical rod installing hole, vertical rod is screwed in vertical rod installing hole by screw thread, and upper-lower position is adjustable, be applicable to dilator various use height requirement, and screw thread spin stablize firm, can lock nut use, improve switching performance further.
The present invention adopts the fixed and movable clamping seats adjustable clamp stressed joint operating-table of clamping seats and clamping plate, coordinate spiral cross-under dilator vertical rod on clamping seats, realize vertical rod to fix in the adjustable adaptation of operating-table side, have that structure is simple, suitability is high, fixing-stable is firm, the advantage that safe and sanitary performance is high.
