Background
The needle holder is a needle holder, which is a surgical instrument in clinical medicine and surgical operation.
The needle holder is mainly used for clamping a suture needle to suture various tissues, sometimes is used for knotting instruments, the point of the needle holder is preferably used for clamping the junction of the middle part and the rear part 1/3 of the suture needle, the clamped needle point is leftwards in most cases, the needle point can be rightwards in special cases, the suture is overlapped 1/3, the overlapped part of the winding is also placed in the needle mouth to facilitate the operation, and if the needle is clamped in the middle of the needle holder, the needle is easy to break.
The needle holding forceps in the prior art do not have a rotating function, suturing in a narrow space is a difficult point of current minimally invasive surgery, especially suturing in different positions and different angles, the existing instrument is in a fixed angle, and a doctor needs to adjust a standing position and replace the instrument to suture a wound conveniently.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects in the prior art and provides a needle holder with a rotatable working end.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a rotatable needle holder of working end, includes the mount, mount one end is connected with two handles through the connecting piece, the mount other end rotates and is connected with the rotation plectane, threaded connection has limit threaded rod on the rotation plectane lateral wall, limit threaded rod is connected with two and is the relative slip panel that sets up through link gear.
Preferably, the connecting piece comprises fixed threaded rods which are respectively positioned at two sides of the fixed frame and are in threaded connection with the fixed frame, and the fixed threaded rods penetrate through the end part of the handle and are in threaded connection with the handle.
Preferably, the link gear includes two fixed plates with limit screw rod tip fixed connection, two fixedly connected with supports the pivot between the fixed plate, it is connected with two linkage connecting rods to rotate in the support pivot, each the linkage connecting rod other end all rotates and is connected with the slip pivot, slip pivot fixedly connected with gangbar, gangbar and slip panel bottom fixed connection.
Compared with the prior art, the utility model has the beneficial effects that:
1. the sliding panel can be rotated by rotating the rotating circular plate on the fixing frame, the adjustment of the angle can be realized without adjusting the standing position by a doctor, and the sliding panel is more convenient and fast.
2. The sliding panel can fix the needle tool by rotating the limit threaded rod, the needle tool is not required to be fixed by the force of hands of a doctor, and the operation of the doctor is more convenient.
3. The angle of the two handles can be adjusted by rotating the fixed threaded rod, so that doctors can control the rotatable needle holding forceps at the working end according to the posture of the doctors used by themselves.
