Abstract
The utility model belongs to the technical field of medical equipment, particularly relates to a plier-type occiput spreader, and solves the technical problem of providing the plier-type occiput spreader which is balanced in tissue load and can reduce partial soft tissue injury. The utility model adopts the technical scheme that the plier-type occiput spreader comprises a plier body formed by a left half plier and a right half plier which are connected through a pin in a hinged manner, the front part of the plier body is provided with plier arms, the middle parts of the plier arms are outward arcs, joint-type crank arm mechanisms are arranged in the middle of the middle parts of the plier arms, the rear parts of the plier body are provided with plier handles, and a locking mechanism is arranged on one of the plier handle; and the plier-type occiput spreader has the characteristics that the front ends of the plier arms are fixedly provided with vertically downward plate-type retractor sheets, the lower edges of the retractor sheets are arcs facing outwards, and the peripheries of the retractor sheets are blunt. The plier-type occiput spreader has the advantages that with the adoption of the retractor sheets, the retracting contact surface with the soft tissue is increased, so that the partial soft tissue load is balanced, and the soft tissue injury is reduced.
Description
Technical field
This utility model belongs to the medical instrument technical field, particularly a kind of forceps-type occiput spreader.
Background technology
Carry out the posterior cranial fossa operation now, the front end of employed forceps-type occiput spreader all adopts pawl formula or hook-type, but because local pressure can make stressed local soft tissue receive big tractive and even damage, influences the postoperative wound healing.
The utility model content
The technical problem that this utility model will solve provides a kind of forceps-type occiput spreader of organizing stress equalization, reducing soft tissue injury.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of forceps-type occiput spreader, and it comprises by the left side half of pin hinge type connection clamps the vice body of forming with right partly pincers, and the front portion of vice body is a tong arm; The centre of tong arm is an arc outwardly, and tong arm has the articulated mechanism of cranking arm in the middle of the middle part, and the vice body rear portion is the pincers handle; The pincers handle is provided with retaining mechanism; Be characterized in: the tong arm front end is fixed with the board-like vertically downward sheet that retracts, and the lower edge that retracts sheet is curved outwardly, is blunt all around.
The utility model has the advantages that: increased with soft tissue and retract contact surface owing to retract sheet, the soft tissue stress equalization reduces soft tissue injury.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of this utility model
The specific embodiment
Shown in accompanying drawing, a kind of forceps-type occiput spreader, it comprises the vice body 1 that clamp on a left side half that is connected by pin 2 hinge types and right half pincers are formed; The front portion of vice body 1 is a tong arm 3, and the centre of tong arm 3 is an arc outwardly, has the articulated mechanism 4 of cranking arm in the middle of tong arm 3 middle parts; Vice body 1 rear portion is pincers handle 5; Pincers handle 5 is provided with retaining mechanism 6, and tong arm 3 front ends are fixed with the board-like vertically downward sheet 7 that retracts, and the lower edge that retracts sheet 7 is curved outwardly; Be that blunt, blunt purpose is in the process of retracting, not to be damaged to soft tissue all around.On prior art, different forceps-type occiput spreaders is just passable as long as retract sheet to front end instead.
