Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of children scalp retractor.
Background technology:
Craniocerebral operation incision scalp and muscle separately all adopt pawl formula or hook-type to draw separately now, but children scalp is thin, and this causes existing scalp retractor not firm because of fixing in operation, throws off easily, make troubles and bother to operation, and increased tissue injury.
The utility model content:
For overcoming the deficiencies in the prior art, this utility model provides a kind of children scalp retractor.
The technical scheme that this utility model technical solution problem is adopted is a kind of children scalp retractor, connects into vice body by the right side half pincers and a left side half pincers by joint pin, and the front portion of vice body is a tong arm, the tong arm middle part is curved, tong arm front end band retracts pawl, and the rear portion is provided with retaining mechanism for pincers handle, pincers handle.
Tong arm of the present utility model is curved, and retractor energy skull circular arc is matched has increased contact area, will strengthen fixed stability greatly, and can not disturb surgical field of view.
In one embodiment, the described pawl that retracts is 3 pawls at right clamp arm, and left clamp arm is 2 pawls, retracts length and damage to reduce scalp, and the wherein preferred described pawl that retracts is blunt pawl.
In one embodiment, but describedly retract the height excuse skin thickness of pawl and change, wherein preferably retract the height of pawl less than 1cm.
In one embodiment, described retaining mechanism is pulled and is locked reed by sector rack, strap wrenches tooth and forms, sector rack is connected on the pincers handle of a left side, band plate hands tooth plate is hinged on the pincers handle of the right side, and locking reed group is connected on the right pincers handle and can flexibly band plate hands tooth plate be engaged on the optional position of sector rack.
In one embodiment, the outside of described pincers handle is provided with some non-slip process.
This utility model is simple in structure, easy to use, is suitable for the physiological structure characteristics of infant scalp, will strengthen the fixed stability of retractor greatly, and can not disturb surgical field of view, has reduced the damage to scalp tissue.
Description of drawings:
Fig. 1 is the overall structure sketch map of children scalp retractor one more excellent example.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments, further illustrate this utility model.Should be understood that these embodiment only to be used to this utility model is described and be not used in the restriction scope of the present utility model.
As shown in Figure 1, a kind of children scalp retractor of this utility model, connect into vice body 1 by the right side half pincers and a left side half pincers by joint pin 2, the front portion of vice body 1 is a tong arm 3, tong arm 3 middle parts are curved, and tong arm 3 front end bands retract pawl 4, and the rear portion is pincers handle 5, pincers handle 5 is provided with retaining mechanism 6, forms a children scalp retractor with this.Tong arm of the present utility model 3 is curved, and retractor can the skull circular arc be matched has increased contact area, will strengthen fixed stability greatly, and can not disturb surgical field of view.The effect that retracts pawl 4 is to retract shallow layer tissue, exposes the deep layer surgical field of view.The described pawl that retracts is 3 pawls at right clamp arm 5b, and left clamp arm 5a is 2 pawls, and the described pawl that retracts is the blunt pawl that retracts.The described height of pawl that retracts is less than 1cm.
The effect of retaining mechanism 6 is to retract edge of wound, expose and to be locked that this retracts fixation clamps after the surgical field of view.Retaining mechanism 6 pulls 6b by sector rack 6a, strap wrenches tooth and locking reed 6c constitutes.Sector rack 6a is connected on the pincers handle 5a of a left side, and band plate hands tooth plate 6b is hinged on the pincers handle 5b of the right side, and locking reed 6c is connected in the optional position that right pincers handle 5b went up and can flexibly band plate hands tooth plate 6b be engaged on sector rack 6a.The profile of tooth of sector rack 6a and band plate hands tooth plate 6b can be made ratchet and ratchet shape respectively; left and right pincers handle 5a/5b can only be drawn close relatively and can not separate relatively; but pulling strap wrenches tooth plate 6b can make it overcome the coupling mechanism force of locking reed 6c and take off with sector rack 6a tooth; left and right pincers handle 5a/5b can freely separate or draw close, thereby makes the pawl 4 that retracts of tong arm 3 front ends draw close or retract.This retaining mechanism 6 has the function that can automatically lock after retracting, reason is when the hands spy retracts fixation clamps thereby left and right pincers handle 5a/5b to be retracted pawl 4 when the shallow-layer soft tissue is retracted by drawing close relatively away from the position to make, band plate hands tooth plate 6b can regulate the position of engagement automatically because of the active force that clothes locking reed 6c is filled in the drive that handle 5b is clamped on the right side, and stop hands to left and right pincers handle 5a/5b pinch active force the time, by the active force of locking reed 6c with sector rack 6a engagement locking.Simultaneously, shallow layer tissue also makes left and right pincers handle 5a/5b tighten to the active force that retracts pawl 4.This retaining mechanism 5 has different characteristics than prior art, can automatically lock, and is still more convenient, and retaining mechanism that retaining mechanism of the prior art for example is made of fan-shaped frid and fishbolt or the like is applicable to this operation retractor too.
Scope of the present utility model is not subjected to the restriction of described specific embodiments, and described embodiment also comprises the method and the component of functional equivalent only as the single example of illustrating this utility model various aspects in this utility model scope.In fact, except content as herein described, those skilled in the art can easily grasp multiple improvement of the present utility model with reference to above description and accompanying drawing.Described improvement also falls within the scope of appended claims.
