Description
Technical field
The present invention relates to technical field of medical equipment more particularly to a kind of endoscope-assistant surgery injection needles.
Background technique
When carrying out the operation such as Minimally Invasive Surgery, hysteroscope operation, Transnasal endoscopy operation, due to being not directly visible operation position
It sets, it will usually perform the operation by various peepholes, such as laparoscope, thoracoscope, hysteroscope, conchoscope, in Minimally Invasive Surgery
Nostril in vagina, Transnasal endoscopy operation in notch, hysteroscope operation etc. is surgical portal.It needs to carry out drug note in operation
When penetrating work, since surgical portal is smaller, syringe needle is limited by the attainable injection position of surgical portal institute, to cannot pass through hand
The position that art entrance reaches generallys use the mode punctured in vitro, but which can cause additional injury to human body, or even cause
Bigger damage.
Existing injection needle there are problems that not injected by surgical portal while, side wall forward and backward to surgery location,
In addition injection depth is also unable to control, too deep to will lead to perforation, and shallowly cannot ensure the useful effect of drug excessively, both wastes medicine
Object could not play therapeutic effect again, be unfavorable for the expansion of follow-up work.
The utility model patent of the patent No. " 201420325844.9 " " intrauterine injection syringe needle " proposes the above problem, and mentions
The solution of " shank and syringe needle are in approximate right angle shape " out controls liquid medicine injection in uterine wall by the curved length of syringe needle
The depth of (inner membrance and muscle layer joint) injects the different location in uterus by rotating syringe metering needle head direction.?
When practical progress uterus drug injection, it is monitored often through hysteroscope；In order to facilitate going on smoothly for operation, it will usually to
Swollen palace liquid is injected in uterus.And the patented technology controls liquid medicine injection in the depth of uterine wall by the curved length of setting syringe needle
Degree, therefore the curved length of syringe needle will not be too long, since uterus is expanded, by rotating syringe metering needle head direction, to uterus
The scheme injected of different location obviously can not achieve.
The utility model patent of the patent No. " 201520425487.8 " " endometrium scar puncture injection needle " proposes note
Penetrate the problem of depth is unable to control, and propose solution: by being arranged protective case on needle handle, protective case is shorter in length than
The length of needle handle, when protective case slides to needle handle front end can will bending syringe needle accommodate in the toggle inner cavity of protective case, protective case to
When needle handle rear end is slided, bending syringe needle is exposed；It is provided with scale on needle handle, solves the problems, such as that injection depth is unable to control, but
It is still without solving the problems, such as to inject uterus different location.
