Abstract
The utility model relates to a needle forcep for laparoscopic surgery, including keeping silent and the handle, keep silent and handle department is provided with the pole of flare -outing, keeps silent to be divided into and keep silent and keep silent down, keeps silent fixed connection down in the one end of pole of flare -outing keeps silent swing joint on, on the pole of flare -outing, and the pole of flare -outing be the cavity tubulose, is provided with traction wire in the pole of flare -outing, and traction wire's one end connection is on the handle, and traction wire's the other end is kept silent on with to be connected that can drive keeps silent and to keep silent under for and is opened or the closure. The utility model discloses simple structure, the design is compact, convenient to use, the pipe diameter of the pole of flare -outing is 4-5mm, keeps silent through the drive of the traction wire in the pole of flare -outing, and the pipe diameter is less, uses the less laparoscopic surgery that more is applicable to of activity angle who makes the needle forcep.
Description
Technical field
The utility model relates to a kind of needle forceps for endoscope-assistant surgery, belongs to technical field of medical instruments.
Background technology
Along with now only needing an otch, the development of clinical treatment technical merit can complete endoscope-assistant surgery. The situation in chamber is projected large display screen by small medical camera. Surgical field of view can be amplified as required, shows trickle structure, than more clear more flexible under naked eyes direct-view. Judgement and the security of the manifesting of the therefore exposure of surgical field of view, pathology fine structure, Operative Range are better than common open chest surgery. But at present conventional needle forceps is because otch is less in the time doing endoscope-assistant surgery clinically, and in operating theater instruments use procedure, the angle of opening and closing causes certain damage to otch too greatly.
Summary of the invention
The purpose of this utility model is in use otch to be caused when handle place opening and closing the problem of secondary injury in order to solve needle forceps in endoscope-assistant surgery, provides a kind of simple in structure, the needle forceps for endoscope-assistant surgery compact to design.
The utility model adopts following technical scheme: a kind of needle forceps for endoscope-assistant surgery, comprise jaw and handle, described jaw and handle place are provided with stretching bar, described jaw is divided into upper jaw and lower jaw, described lower jaw is fixedly connected on one end of stretching bar, described upper jaw is movably connected on stretching bar, described stretching bar is hollow tubular, in described stretching bar, be provided with traction steel wire, one end of described traction steel wire is connected on handle, and the other end of described traction steel wire is connected with upper jaw and can drives upper jaw to open with respect to lower jaw or closure.
Further, the bar footpath of described stretching bar is 4～5mm.
Further, the length of described upper jaw and lower jaw is 6～20mm.
Further, angle when described upper jaw and lower jaw open is 15～55 °.
Further, the length of described needle forceps is 300～550mm.
Further, described upper jaw and lower jaw are elbow.
Further, described handle is set to refer to ring type, and the top of described handle is provided with forniciform finger circle hook.
The utility model is simple in structure, compact to design, easy to use, the caliber of stretching bar is the puncture outfit that 4.5mm can pass in and out 5mm smoothly, jaw drives by the traction steel wire in stretching bar, caliber is less, makes the activity point of view of needle forceps less, and the handle more laborsaving and balance in the time opening that is arranged so that refers to enclose hook is better more suitable for thoracoscope and laparoscopic surgery.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model upper jaw is the schematic diagram of elbow.
Reference numeral: jaw 1, upper jaw 1-1, lower jaw 1-2, stretching bar 2, handle 3, refer to enclose hook 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As Figure 1-Figure 2, a kind of needle forceps for endoscope-assistant surgery, comprise jaw 1 and handle 3, jaw 1 and handle 3 places are provided with stretching bar, jaw 1 is divided into upper jaw 1-1 and lower jaw 1-2, the length of upper jaw 1-1 and lower jaw 1-2 is 6～20mm, upper jaw 1-1 and lower jaw 1-2 can also be elbow, lower jaw 1-2 is fixedly connected on one end of stretching bar 2, upper jaw 1-1 is movably connected on stretching bar 2, stretching bar 2 is hollow tubular, the caliber of stretching bar 2 is 4.5mm, in stretching bar 2, be provided with traction steel wire, one end of traction steel wire is connected on handle 3, the other end of traction steel wire is connected with upper jaw 1-1 and can drives upper jaw 1-1 to open with respect to lower jaw 1-2 or closure, angle when upper jaw 1-1 and lower jaw 1-2 open is 15～55 °, the length of needle forceps is 300～550mm, handle 3 is set to refer to ring type, the top of handle 3 is provided with forniciform finger circle hook 4.
Using method: in endoscope-assistant surgery, the jaw of needle forceps 1 and the stretching bar 2 of part are stretched in otch, hold handle 3, handle 3 drives the traction steel wire in stretching bar, traction steel wire drives upper jaw 1-1 to open or closing motion with respect to lower jaw 1-2, and can be by handle 3 adjusting jaws to proper angle, the opening and closing of jaw 1 can not cause secondary injury to otch, the caliber of stretching bar is less, can pass in and out smoothly the puncture outfit of 5mm, therefore the otch of endoscope-assistant surgery is less, can reduce the surface of a wound in operation, be conducive to patient's recovery, what refer to circle hook is arranged so that handle is more laborsaving and balance is better in the time opening, be applicable in thoracoscope and laparoscopic surgery.
