Technical field

The present invention relates to medical instruments fields more particularly to a kind of adjustable clamp away from bringing device.

Background technique

It is abundant exposure surgical field of view in surgical procedures, needs to ligature the fracture blood vessel in notch to prevent Bleeding.Be for the method for hemostasis by ligation at present stopped blooding using the clips such as ligation clip and tissue folder, but utilize ligation clip and The clips such as tissue folder (structure of ligation clip and tissue folder is almost the same) have a problem that stop blooding, because these clips are in reality Could be used with must be installed to clip on Clip Applier in the process (is by two each self installations of collet of clip when specific installation Onto Clip Applier), but since the size difference of the clip of different size is larger, and the clip of each size can only be with a kind of ruler Very little corresponding Clip Applier uses, so must prepare the Clip Applier of sizes during operation every time in case operation uses.

Summary of the invention

The present invention is in view of the above-mentioned problems, propose a kind of adjustable clamp away from bringing device.

The technical solution adopted by the present invention is as follows:

A kind of adjustable clamp is away from bringing device, including fixed handle, flexible handle, elastic component, operation casing, operating stick and tune Section structure, described fixed handle one end are fixed on operation casing, and described flexible handle one end and fixed handle are rotatably assorted Together, the elastic component is set between flexible handle and fixed handle, and the elastic component is used for flexible handle and fixed hand Handle flicks, and the operating stick is movably set in operation casing, mounting portion is provided in the operating stick, the mounting portion is used for Install collet, the installation position in operation casing outside, the adjustment structure be set to operation casing on or operating stick on or grasp Make between bar and operation casing, the regulating device is for the distance between adjust installation portion and operation casing, the movable hand Handle is for driving operating stick to move in operation casing.

Operation portion in the specific present apparatus is for installing two collets, due to being provided with adjustment structure, so that installation The distance between portion and operation casing nozzle are adjustable, after two collets are installed on the mounting portion of operating stick, operation Bar movement is with collet movement, after the nozzle for manipulating casing resists two collets, can mutually draw close clamping between two collets, So when installing various sizes of collet, mounting portion be at a distance from operation casing nozzle it is different, the present apparatus by Adjustment structure is adapted to a variety of rulers so that the distance between nozzle of the mounting portion of operating stick and adjusting sleeve pipe is adjustable Very little collet, it is easy to operate, it is adaptable.Elastic component in specific this case can be elastic slice, be also possible to spring.

The present apparatus is by setting adjustment structure, so that the distance between operating stick upper mounting portion and operation casing can be adjusted Section adapts to the installation requirement of sizes collet, easy to use, adaptable.

Optionally, the adjustment structure includes that adjusting sleeve and screw thread, described operating stick one end are provided with the screw thread, institute It states adjusting sleeve to be installed on the screw thread, described flexible handle one end is for resisting the adjusting sleeve.

It optionally, further include seal rubber plug and rotation pull head, seal rubber plug and rotation pull head are set to the pipe of operation casing On wall.

Optionally, the adjustment structure includes sliding block and trigger, and face of gear is provided on the sliding block and trigger, described Sliding block and trigger are meshed together by face of gear, the sliding block together with operating stick secure fit, the sliding block with it is described Operation cannula slide is combined together, and the trigger is rotatably dispose on fixed handle by fixing axle.

Optionally, further include splice sleeve connector, through-hole, the fixed hand are offered on the fixing sleeve of the fixed handle It is fixed together between the fixing sleeve and operation casing of handle by splice sleeve connector, and operating stick runs through the fixing sleeve On through-hole.

Optionally, it is fixedly installed head in the operating stick, active joint, institute are fixedly installed on the flexible handle The active joint for stating flexible handle drives operating stick to move by resisting the head of operating stick.

It optionally, further include collet connector, the collet connector is installed on operation casing, and the installation position of operating stick In outside collet connector；After being equipped with collet on the mounting portion of the operating stick, the collet connector is for driving between collet Between mutually draw close and be adjacent to.

Be arranged collet connector purpose be in order to make two collets draw close be adjacent to when it is more smooth, because if only according to Nozzle by operating casing itself is adjacent to draw close two collets, and operation casing is possible to block two collets, so pass through Two collets are clamped using collet connector.

It optionally, further include swivel, fixed be arranged of the swivel is mounted on splice sleeve connector, and described turn Dynamic connector is used to for splice sleeve connector, fixing sleeve and operation casing three being fixedly clamped together.

Optionally, fixing buckle is provided on the fixed handle, the trigger is rotatablely installed by the fixing axle in solid Determine on the fixing buckle of handle.

Optionally, fixed point is provided in the operating stick, the sliding block is fixed on the fixed point of operating stick.

The beneficial effects of the present invention are: by setting adjustment structure, so that between operating stick upper mounting portion and operation casing Distance it is adjustable, adapt to sizes collet installation requirement, it is easy to use, it is adaptable.
