Abstract
The utility model discloses a built-in grasper of an interventional catheter for minimally invasive surgery. The built-in grasper comprises an expandable grasper head, spring connection points, the interventional catheter, an internal guide wire, a fixed jackscrew, an internal shaft rod, a spring, an inner groove fixing pin, a rear handle, a supporting spring piece, a front handle and a handle connection shaft. The built-in grasper is matched with an electronic imaging system, a cold light source and an electrocoagulation system before use. The expandable grasper head is retracted into the interventional catheter inwards firstly, and the interventional catheter is inserted into a human body. The expandable grasper head is sent out of the interventional catheter by controlling the rear handle and the front handle to drive the internal guide wire, expands under the action of the spring connection points positioned at the rear portion of the expandable grasper head to perform grasp in the body, and is retracted into the interventional catheter to be taken out. The built-in grasper has the advantages of being simple in operation and safe and reliable and serves as an ideal surgical instrument used in the minimally invasive surgery.
Description
Technical field
The present invention relates to the technical field of operating theater instruments, the built-in nipper of espespecially a kind of Minimally Invasive Surgery interposing catheter.
Background technology
Wicresoft's medical science is the medical science growing up of 21 century, Minimally Invasive Surgery is the multiple technologies such as the modern advanced electronic imaging of application, cold light source, coagulation system, replace naked eyes direct-view with electron mirror imaging, replace traditional operation cutter with elongate chamber mirror apparatus, make every effort to, with minimum otch path, complete diagnosis and treatment to internal lesions.Along with Wicresoft's Medical Technology development, Minimally Invasive Surgery apparatus is also innovated appearance constantly.But in the time doing the Minimally Invasive Surgery of particular/special requirement, while using nipper as needs, traditional surgical grasping forceps is not suitable for using, and brings certain inconvenience to operation.
Summary of the invention
The built-in nipper of a kind of Minimally Invasive Surgery interposing catheter of the present invention, adopt interposing catheter anterior built-in can expanding nipper head, by forward handle and backward handle control, realize the object that Minimally Invasive Surgery intracavity nipper is got.
To achieve these goals, technical solution of the present invention is: the built-in nipper of a kind of Minimally Invasive Surgery interposing catheter by can expanding nipper head, spring junction point, interposing catheter, inner guide wire, fixing jackscrew, inner shaft lever, spring, inside groove fixator pins, back handle, support spring sheet, front hand grip, handle connecting shaft form; Interposing catheter arrange with spring junction point can expanding nipper head, interposing catheter rear portion is connected with front hand grip top, in front hand grip, inside arranges interior blank pipe passage, interior blank pipe channel interior is provided with inner shaft lever, front hand grip is connected by handle connecting shaft with back handle, is provided with support spring sheet between front hand grip and back handle; Interposing catheter inside arranges inner guide wire, inner guide wire is anterior to be connected with spring junction point that can expanding nipper head, inner shaft lever front portion connection in front hand grip top, rear portion, inner shaft lever rear portion is connected with the inside groove fixator pins on back handle top through the interior blank pipe passage of front hand grip, inner shaft lever outside at front hand grip and back handle is provided with spring, is the built-in nipper of Minimally Invasive Surgery interposing catheter.
Beneficial effect of the present invention is: before using, coordinate electronic imaging, cold light source, coagulation system, first can expanding nipper head retraction interposing catheter inside, interposing catheter is inserted in human body, by controlling forward handle and forward handle, drive inner guide wire to send interposing catheter by expanding nipper head, can implement nipper operation in body by expanding nipper head spreading nipper head under the spring junction point effect at rear portion, and take in interposing catheter and take out of; Having advantage simple to operate, safe and reliable, is operating theater instruments desirable in Minimally Invasive Surgery.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Accompanying drawing is the built-in nipper schematic diagram of a kind of Minimally Invasive Surgery interposing catheter.
In figure: 1, can expanding nipper head, 2, spring junction point, 3, interposing catheter, 4, inner guide wire, 5, fixing jackscrew, 6, inner shaft lever, 7, spring, 8, inside groove fixator pins, 9, back handle, 10, support spring sheet, 11, front hand grip, 12, handle connecting shaft.
Detailed description of the invention
Shown in accompanying drawing, the built-in nipper of a kind of Minimally Invasive Surgery interposing catheter by can expanding nipper head 1, spring junction point 2, interposing catheter 3, inner guide wire 4, fixing jackscrew 5, inner shaft lever 6, spring 7, inside groove fixator pins 8, back handle 9, support spring sheet 10, front hand grip 11, handle connecting shaft 12 form; Interposing catheter 3 arrange with spring junction point 2 can expanding nipper head 1, interposing catheter 3 rear portions are connected with front hand grip 11 tops, in front hand grip 11, inside arranges interior blank pipe passage, interior blank pipe channel interior is provided with inner shaft lever 6, front hand grip 11 is connected by handle connecting shaft 12 with back handle 9, between front hand grip 11 and back handle 9, is provided with support spring sheet 10; Interposing catheter 3 inside arrange inner guide wire 4, inner guide wire 4 is anterior to be connected with spring junction point 2 that can expanding nipper head, rear portion is connected with inner shaft lever 6 front portions in front hand grip 11 tops, inner shaft lever 6 rear portions are connected with the inside groove fixator pins 8 on back handle 9 tops through the interior blank pipe passage of front hand grip 11, be provided with spring 7 in front hand grip 11 and inner shaft lever 6 outsides of back handle 9, be the built-in nipper of Minimally Invasive Surgery interposing catheter.
The above; embodiment is only that the preferred embodiment of the present invention is described; not scope of the present invention is limited; under the prerequisite of spirit that does not depart from the technology of the present invention; various distortion and improvement that this area engineers and technicians make technical scheme of the present invention, all should fall in the definite protection domain of claims of the present invention.
