Abstract
The utility model discloses retraced protective vessel forceps, which comprise a pair of forcep rods which comprise forcep handles, a latch and forcep blades, wherein the a shaft hole is arranged between the forcep handles and the forcep blades on the forcep rods, and the forcep rods are intersected in the shaft hole, and are hinged through a shaft joint. The utility model is characterized in that the front ends of the forcep blades are bent along the direction of the axis of the shaft joint and are retraced towards the force handles. By adopting the retraced structure, when the retraced protective vessel forceps of the utility model transmit fretsaw to masseteric space from pterygomandibular space by mandibular notch, the passing position is more shallow, and can be far away from basis cranii, the view is wider, light can easily reach, so that the fletsaw can quickly and conveniently be guided to pass through, the operation time can be saved, and the operation efficiency can be improved. The utility model has simple structure and convenient use. Compared with the right-angle vessel forceps in the prior art, the utility model can not increase the cost.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of inflection protection vascular forceps that the clamping scroll saw passes sigmoid notch when being used for mandibular bone ascending branch stringer osteotomy.
Background technology
Mandibular bone ascending branch stringer osteotomy, the open reduction internal fixation is the modal operation technique of treatment fracuture of mandibular condyloid process, usually use the right angle vascular forceps to transmit scroll saw and enter the masseter gap via sigmoid notch, but the position of walking is very dark, near basis cranii from pterygomandibular space, the visual field is narrower, light is difficult to reach, and in most cases, relies on patient's sensation and experience, make repeated attempts, this simple action need that transmits is about l hour sometimes.Prolong operating time, increase the damage and the risk of operation.Problem does not cause surgical enough attention as yet hereto, does not see effectively ways of addressing this issue as yet.
Summary of the invention
The purpose of this utility model provides a kind of inflection protection vascular forceps, can guide scroll saw to walk quickly and easily, saves operating time, improves operating efficiency.
In order to achieve the above object, the technical solution of the utility model is: a kind of inflection protection vascular forceps comprises: a pair of claw beam of being made up of pincers handle, snap close, pincers leaf is provided with axis hole between pincers handle above the claw beam and the pincers leaf, this intersects at axis hole to claw beam, and hinged with joint; It is characterized in that: the front end of described pincers leaf turns back along the direction bending of joint axis and to the direction of pincers handle.
Each is provided with groove accordingly along the direction of pincers leaf bending on described two relative faces of pincers leaves.
Be provided with horizontal lines in the groove of described two pincers leaves.
When inflection protection vascular forceps was closed, the cross section of the front end of described pincers leaf was circular.
The smooth circle of the head of described pincers leaf is blunt.
The beneficial effects of the utility model are: because inflection of the present utility model protection vascular forceps has adopted the inflection structure; enter masseter gap from pterygomandibular space via sigmoid notch so use inflection protection vascular forceps of the present utility model to transmit scroll saw; the position of walking is superficial; can be away from basis cranii; wider field of view, light reaches easily, and then can guide scroll saw to walk quickly and easily; save operating time, improve operating efficiency.This utility model is simple in structure, and is easy to use, compares with making right angle of the prior art vascular forceps, increases cost hardly.
Below in conjunction with embodiment and accompanying drawing this utility model is done a detailed description.

Fig. 4 is the front schematic view of pincers leaf, the A-A view of Fig. 3.
The specific embodiment
Embodiment:
Referring to Fig. 1 to Fig. 4, a kind of inflection protection vascular forceps comprises: a pair of claw beam of forming by pincers handle 2, snap close 3, pincers leaf 41, be provided with axis hole 6 between pincers handle above the claw beam and the pincers leaf, and this intersects at axis hole to claw beam, and hinged with joint 5; The front end of described pincers leaf turns back along the direction bending of joint axis and to the direction of pincers handle, as depicted in figs. 1 and 2.
Owing to adopted the inflection structure; enter masseter gap from pterygomandibular space via sigmoid notch so use inflection protection vascular forceps of the present utility model to transmit scroll saw; the position of walking is superficial; can be away from basis cranii; wider field of view, light reaches easily, and then can guide scroll saw to walk quickly and easily; save operating time, improve operating efficiency.
Respectively be provided with groove 4-1 accordingly referring to Fig. 4 direction along the bending of pincers leaf on the relative face of described two pincers leaves.When inflection protection vascular forceps was closed, it was circular cavity that two grooves form a cross section, and the diameter of its diameter and scroll saw is suitable.At pincers Ye Weiduan, groove eight goes out to clamp a side of leaf.Such structure can make scroll saw snap in to be convenient in the groove operation of performing the operation.
In the groove of described two pincers leaves, be provided with horizontal lines 4-2.Such structure can make groove more effectively grip scroll saw.
When inflection protection vascular forceps was closed, the cross section of the front end of described pincers leaf was circular.Such shape can make the operation receiveing person reduce misery, and the smooth circle of the head of described pincers leaf is blunt.
