Description
Technical field
The present invention relates to technical field of medical instruments, be specifically related to a kind of forceps-type occiput spreader for infants.
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 the posterior cranial fossa physiological structure, and this causes existing occiput spreader not firm because of fixing in operation, throws off easily, make troubles and bother to operation, and increased tissue injury.
Summary of the invention:
For overcoming the deficiencies in the prior art, the invention provides a kind of forceps-type occiput spreader for infants.
The technical scheme that technical solution problem of the present invention is adopted is a kind of forceps-type occiput spreader for infants, connect into vice body by the right side half pincers and a left side half pincers by joint pin, the front portion of vice body is a tong arm, the bottom surface at tong arm middle part is curved, tong arm has the mechanism of cranking arm in the middle of the middle part, the tong arm front end has and retracts pawl, and the rear portion is provided with retaining mechanism for pincers handles, pincers handle.
Tong arm of the present invention has the mechanism of cranking arm, and the arc of tong arm and skull circular arc are more matched, and has increased contact area, will strengthen the fixed stability of retractor greatly, and can not disturb surgical field of view.
In one embodiment, the described mechanism of cranking arm is an articulation mechanism, is convenient to can make tong arm curved as long as apply downward force at the pincers handle in the operation.
In one embodiment, the described pawl that retracts is curved, can make the wild exposed area of art bigger, and the wherein preferred described pawl that retracts is blunt pawl, to reduce tissue injury.
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, the rear end of described tong arm also has the fixture of other operated devices, and described fixture affixed and tong arm upper surface or lateral surface can be fixed various operated devices.For example: snakelike retractor, slurry shape retract plate, cold light source fiber waveguide beam, continue deep operated devices such as suction catheter and micro dissecting instrument.Its applied range not only can retract fixedly shallow layer tissue, and has multiple function and be convenient to the deep microsurgical procedure especially.
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.
The present invention is simple in structure, easy to use, is suitable for the physiological structure characteristics of infant scalp and posterior cranial fossa, will strengthen the fixed stability of retractor greatly, and can enlarge surgical field of view, has reduced the damage to scalp tissue.
Description of drawings:
Fig. 1 is the overall structure sketch map of forceps-type occiput spreader for infants one more excellent example.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.
As shown in Figure 1, a kind of forceps-type occiput spreader for infants of the present invention, 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, the bottom surface at tong arm 3 middle parts is curved, and tong arm has the mechanism of cranking arm 7 in the middle of the middle part, and tong arm 3 front ends retract pawl 4 for having, the rear portion is provided with retaining mechanism 6 for pincers handle 5, pincers handle.
Tong arm of the present invention has the mechanism of cranking arm, and the arc of tong arm and skull circular arc are more matched, and has increased contact area, will strengthen the fixed stability of retractor greatly, and can not disturb surgical field of view.
The described mechanism 7 of cranking arm is articulation mechanism 7, is convenient to can make tong arm curved as long as apply downward force at the pincers handle in the operation.
The described pawl 4 that retracts is curved, can make the wild exposed area of art bigger, and the wherein preferred described pawl 4 that retracts is blunt pawl, to reduce tissue injury.But describedly retract the height excuse skin thickness of pawl 4 and change, wherein preferably retract the height of pawl 4 less than 1cm.The rear end of described tong arm 3 also has the fixture 8 of snakelike retractor.
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 invention 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 various aspects of the present invention in the scope of the invention.In fact, except content as herein described, those skilled in the art can easily grasp multiple improvement of the present invention with reference to above description and accompanying drawing.Described improvement also falls within the scope of appended claims.
