Abstract
The utility model discloses a kind of band groove Minimally Invasive Surgery vascular forceps.Comprise left binding clip, right binding clip, connecting axle or connecting rod, right clamp arm, left forearm, left pincers handle, right pincers handle, handle, fixing latch, left binding clip and right binding clip are oval shape, and front end is with an oval recess.The wide 1.5mm of this groove external diameter, the wide 1mm of internal diameter.Left binding clip, right binding clip and groove are coarse rubbing surface.Right clamp arm and left forearm are the curved shape in the same way at 26-32 ° of angle.This utility model is by the groove design of the circular binding clip of oval type, and when surgical operation, particularly Minimally Invasive Surgery more easily hooks and brings stitching thread into, makes apparatus enter deep tissue, carries out operating knot, original position knotting, separate tissue etc. and correctly process.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of band groove Minimally Invasive Surgery vascular forceps.
Background technology
Clinical operation is particularly in thoracic surgery minimal invasive surgical procedures, and vascular forceps can play chorista, blood vessel, the effect of [1] grasping tissue, blood vessel.Owing to being subject to the blood vessel angle of position, deep tissue and small space impact in operation, existing surgical instrument operation comprises that vascular forceps, knot pusher, wire twister etc. are many performs the operation at small space the while of operating theater instruments.The factors such as, blood vessel angle narrow and small by surgical field of view limit, and light is difficult to reach operative region, in most cases, with the experience of patient, need increase the difficulty of operation, damage and risk.Chinese utility model patent CN202198643.U discloses the utility model patent that name is called " Multifunctional vessel forceps ", and Chinese utility model patent CN202761372.U discloses the utility model patent that name is called " doublejointed sponge holding forceps ".Above-mentioned two kinds of patents all occur to solve produced problem in operation, but or can not deal with problems completely.
Utility model content
The purpose of this utility model is to overcome above deficiency, provides a kind of doublejointed or the simple joint vascular forceps that are conducive to the band groove of Minimally Invasive Surgery operation.
For achieving the above object, this utility model adopts following technical scheme: comprise left binding clip, right binding clip, connecting axle or connecting rod, right clamp arm, left forearm, left pincers handle, right pincers handle, handle, fixing latch, it is characterized in that: left binding clip and right binding clip are oval shape, front end is with an oval recess.
This groove (the wide 1.5mm of external diameter, the wide 1mm of internal diameter.Left binding clip, right binding clip and groove are coarse rubbing surface.Right clamp arm and left forearm are the curved shape in the same way at 26-32 ° of angle.
The beneficial effects of the utility model are: the unique design of band groove, in narrow space, can play knot, knotting, the effect that is separated, decrease and manyly operating theater instruments used the operation difficulty and tissue injury that cause simultaneously, improve minimal invasive operation effect.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation (doublejointed).
Fig. 2 is this utility model simple joint structural representation.
Fig. 3 is tong head schematic diagram in this utility model.
Fig. 4 is the schematic diagram of oval recess in this utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
Referring to accompanying drawing, this vascular forceps can be divided into simple joint vascular forceps (Fig. 2) and doublejointed vascular forceps (Fig. 1), comprise left binding clip 2, right binding clip 1, connecting axle 7 or connecting rod 7-1, right clamp arm 3, left forearm 4, left pincers 6, right pincers are 5, handle 8, fixing latch 9, left binding clip 2 and right binding clip 1 are oval shape, and front end is with an oval recess 10.Its structure is all prior art.Band groove doublejointed vascular forceps comprises the circular binding clip of left and right band groove, left and right tong arm, the binding clip of institute's art and tong arm one, left and right pincers handle, connecting rod, described connecting rod and left and right tong arm form the first joint, and connecting rod and the left and right handle that clamps are connected to form second joint.Connecting rod is hollow structure, arranges trace in connecting rod, and trace one end is clamped being connected with left, and the trace other end clamps being connected with right, is controlled the folding of right clamp arm by the folding of left pincers handle.Band groove simple joint vascular forceps comprises the circular binding clip of left and right band groove, left and right tong arm, described binding clip and tong arm one, left and right pincers handle, connecting axle, described connecting axle one end is clamped being connected with left, the other end is connected with right clamp arm, is controlled the folding of right clamp arm by the folding of left pincers handle.These are all very ripe.Difference of the present utility model is oval shape at left binding clip 2 and right binding clip 1, and front end is with an oval recess 10.The wide 1.5mm of this groove 10 external diameter, the wide 1mm of internal diameter.Left binding clip 2, right binding clip 1 and the coarse rubbing surface of groove 10.Right clamp arm 3 and left forearm 4 are the curved shape in the same way at 26-32 ° of angle.Owing to have employed the unique design of band groove, make full use of groove, make in narrow space, can play knot, knotting, be separated effect, decrease and manyly operating theater instruments is used the operation difficulty and tissue injury that cause simultaneously, improve minimal invasive operation effect.
