Description
Technical field
This utility model relates to a kind of operating room medical equipment commonly used, is specifically related to a kind of various big hospital that is used for and carries out the chamber mirror needle holder that minimal invasive surgical procedures such as thoracic surgery, department of general surgery, gynecological are often used.
Background technology
Chamber mirror needle holder is to be used for various big hospital to carry out the needle holder tool that minimal invasive surgical procedures such as thoracic surgery, department of general surgery, gynecological are often used.Existing various big hospital use the scope needle holder comprise two kinds, a kind of is that pure chamber mirror uses needle holder, another kind is that the technology of traditional needle holder is extended, and has following shortcoming:
1) pure chamber mirror use needle holder is used more at department of obstetrics and gynecology and department of general surgery; Such needle holder can be good at gripping suture needle, but apparatus is huge, even use light material still can feel very heavy; And shortage feel; Need go out pin with the sensation inserting needle, when accurate operations such as anastomosis of blood vessel, be not suitable for using.For the doctor on no fine chamber mirror basis, use the needle holder inserting needle at intracavity, go out pin, turn to and wait operation time-consuming especially, require great effort.So just prolonged operating time, brought unnecessary misery to the patient.
2) needle holder that is extended by traditional instruments is on the basis that conventional needle is held, to add long handle, can operate at a distance like this, and also since roughly similar with traditional instruments, can be accepted by vast operative doctor more easily.But this apparatus is owing to be that simple handle extends, and joint position is constant, when needs are held pin again, according to lever principle, must strengthen the movable amplitude of handle, in pure endoscope-assistant surgery, receives the restriction of otch, can't accomplish.Can only be again take out suture needle and outside the chamber, hold pin again or turn to etc., so just lost real chamber mirror operational meaning.
The utility model content
This utility model purpose is the defective to above-mentioned prior art, and a kind of chamber mirror needle holder is provided, and this chamber mirror needle holder is easy and simple to handle, practical; Can also carry out accurate operation; Be suitable for the operation of chamber mirror, can the fine needs that satisfy the medical worker, reach medical worker's intended purposes.
To achieve these goals, the technical scheme taked of this utility model is:
A kind of chamber mirror needle holder of this utility model; Comprise hold syringe needle, hold needle handle, pull bar and handle; Said hold the needle handle front end for hold syringe needle, the said needle handle rear end of holding connects said pull bar; The said syringe needle of holding is held syringe needle and is fixedly held syringe needle and form by activity, and said pull bar holds syringe needle with said activity respectively and said handle is connected.
The said needle handle of holding is the fixed sleeving with elongated hollow.
Said chamber mirror needle holder also comprises support and brace; Said support is fixed on said holding on the needle handle; Said pull bar is held needle handle sleeve pipe and said activity and is held syringe needle and flexibly connect through said, and said pull bar flexibly connects the head end and the flexible connection of said support of said handle through brace and said handle.
The said syringe needle and said fixedly held is held the needle handle riveted joint and is one, and said activity is held syringe needle and can be hinged on fixedly versatilely and hold on the syringe needle.
There is clean-out opening said rear end of holding needle handle, on the said clean-out opening block is arranged.
Said hold syringe needle open the back maximum angle be 30 °.
Syringe needle is held in said activity and the said occlusal surface of fixedly holding syringe needle is pressed the single face interlock of handling for scalding, and opening the back length of action is 1.0cm.
The bottom of said handle is provided with spacing latch.
The said needle handle length of holding is 10-12cm, and diameter is 0.4-0.6cm.
The beneficial effect of this utility model is: the design of holding the doublejointed that syringe needle and handle be connected through pull bar respectively with activity; The chamber mirror needle holder of this utility model has feel preferably; And it is littler than traditional instruments that pin is held head; Carrying out can be good at migration wherein when vascular anastomosis or other little pipelines coincide, and do not stopping the visual field, can carry out meticulous operation.
