Description
Technical field
The utility model belongs to the field of medical instrument technology, refers specifically to a kind of lip and cheek mass fixing device.
Background technology
In lip and cheek mass excising operation, on the one hand, the skin on lip and cheek two sides and mucous membrane are soft tissue, at this
Mass has apparent sense of touch, in this way it is easy to determine position, but it is also easy to happen sliding simultaneously, it is difficult to it is fixed.On the other hand, lip and cheek is soft
The short texture of tissue, blood fortune is abundant, needs the blood vessel for oppressing both sides simultaneously that could reduce intraoperative hemorrhage.Therefore, for hemostasis
With fixed consideration, mass must be gripped from the two sides of lip and cheek in art.The visual area of this kind of operation is smaller, practical operation
In usually also need to assistant's close fit surrounding soft tissue of art area oppressed with manual pressure, to play fixed and anastalsis,
This just further increases upper inconvenient and staff the burden of operation.
Existing tongue forceps can be used for the fixation of lip and cheek mass, but tightness is clamped for controlling two cyclic annular binding clips
Latch spacing is larger, easily leads to that gripping for mass is too tight or too loose, and tension is easy to cause skin and mucous membrane in actual use
It dampens, then intraoperative blood loss is larger for pine excessively.The weight of tongue forceps is larger simultaneously, and clamp handle is longer, for fixing the operation of lip and cheek mass
On it is more inconvenient.Therefore, to design a kind of special setting tool for lip and cheek mass excising operation very necessary.
Invention content
The utility model be intended to provide it is a kind of to lip and cheek mass have the good device for gripping effect, Neng Goujian
Change the surgical procedure that mass is extractd, while being not easy skin and mucosal cell damage to lip and cheek.
Lip and cheek mass fixing device described in the utility model includes the hinged interior clamping limb in end and outer clamping limb, is hinged
Limit screw on the inside of interior clamping limb and across outer clamping limb, is loaded on the regulating nut of Limit screw free end, and is used for
Flick the elastomeric element of interior clamping limb and outer clamping limb.The outer clamping limb includes outdoor handle and is fixed at outdoor handle front end court
The spoon-shaped collet of inner bulge, interior clamping limb include inner handle and the cambered surface for being fixed at inner handle front end and the cooperation of spoon-shaped collet
Annular chuck.
The inner handle and outdoor handle are flat metal plate part, and both sides extend a pair of hinge ear turned down to homonymy outside end, interior
Handle and outdoor handle pass through the axis pin of hinge ear hinged by one.
The symmetrical trepanning in the inner handle stage casing is simultaneously installed with a bow-shaped ring, the Limit screw inner end radially drill and with
Bow-shaped ring, which is worn, to be connect, and the outdoor handle stage casing is equipped with the slot hole that a width is adapted with Limit screw outer diameter along its length.
Preferably, an elastic washer is housed on the annular chuck.
The elastic washer includes the washer body adaptable with cambered surface on the inside of annular chuck and outside washer body inner circumferential
The fixation flange of the circle and annular chuck interference fit that extend.
As the first embodiment of the utility model, the elastomeric element is to be placed on axis pin and both ends are tight against interior hand
The torsional spring of handle and outdoor handle.
As second of embodiment of the utility model, the elastomeric element is the spring being placed on Limit screw.
Lip and cheek mass fixture structure described in the utility model is simple, easy to use, can be played to mass preferably
Grip and haemostatic effect, and clamping force can fine adjustment, be not easy, to skin and mucosal cell damage, to help to improve
Procedure efficiency has good application value.

Specific implementation mode
Lip and cheek mass fixing device described in the utility model is made furtherly in the following with reference to the drawings and specific embodiments
It is bright.
As shown in figs. 1 to 6, lip and cheek mass fixing device described in the utility model includes the hinged interior clamping limb 1 in end
With outer clamping limb 2, it is articulated with 1 inside of interior clamping limb and the Limit screw 3 across outer clamping limb 2, is loaded on 3 free end of Limit screw
Regulating nut 4, and the elastomeric element for flicking interior clamping limb 1 and outer clamping limb 2.Outer clamping limb 2 includes outdoor handle 21
Be fixed at 21 front end of outdoor handle inwards raised spoon-shaped collet 22, interior clamping limb 1 includes inner handle 11 and is fixed at
The cambered surface annular chuck 12 that 11 front end of inner handle coordinates with spoon-shaped collet 22.
The clamping pine that can preferably control interior clamping limb and outer clamping limb to art area position by the way that screw rod and nut is arranged
Tight degree.The mating surface of spoon-shaped collet and annular chuck is cambered surface, can preferably be bonded facial tissue, clamping it is firm and keenly feel compared with
It is small, preferable fixation and haemostatic effect can be played, and be not easy to cause to dampen to skin and mucous membrane.Spoon-shaped collet on outer clamping limb
Mass can also be jacked up to and be played good supporting role, be convenient for surgical removal.It can be according to actual needs by screw rod and nut
Clamping tightness is accurately adjusted, elastomeric element can be that device introduces elastic buffer mechanism, make elastic by nut adjusting clamping
The process of degree more smoothes out.
Inner handle 1 and outdoor handle 2 are flat metal plate part, and both sides extend a pair of hinge ear 5 turned down to homonymy, interior hand outside end
Handle 1 and outdoor handle 2 pass through the axis pin 6 of hinge ear 5 hinged by one.
The symmetrical trepanning in 1 stage casing of inner handle is simultaneously installed with a bow-shaped ring 13, Limit screw 3 inner end radially drill and and arch
Ring 13, which is worn, to be connect, and 2 stage casing of outdoor handle is equipped with the slot hole 23 that a width is adapted with 3 outer diameter of Limit screw along its length.Using this
Kind of connection type can make Limit screw have a preferable adaptivity, internal, outer clamping limb have under different folding angles compared with
Good limit effect.The structure of above-mentioned inside and outside clamping limb is relatively simple, may be designed to integrated punching molded part, reduces manufacture
Cost.
