Description
Technical field
The utility model is related to medical auxiliary equipments, are clamped more particularly, to a kind of novel cavity mirror.
Background technology
A kind of Minimally Invasive Surgery of endoscope-assistant surgery, tiny light source, video camera and surgical instruments are inserted by notch into human body,
Then doctor implements operation by the image being transferred in monitor.In endoscope-assistant surgery, common hysteroscope clamp takes endoceliac
Tumour block, tumour, slough etc..Existing hysteroscope pincers are mostly long rod structure, and one end of stock is provided with joystick, the other end
It is provided with fixed pliers head and movable binding clip.Two binding clips of above-mentioned hysteroscope chamber are slim-lined construction, and holding area is small, it is necessary to repeatedly press from both sides
It takes, it is time-consuming and laborious, and be also easily caught broken tumour block, slough etc. in clamping process, increase operating difficulty；It is gripping
During larger tissue, a net cover is usually connected on binding clip, net cover mouth is tightened after tissue is entangled and presss from both sides out tissue in vitro, net cover set
Take the time long, it is troublesome in poeration, influence procedure efficiency.
The content of the invention
The utility model aim is that providing a kind of novel cavity mirror clamps, and the hysteroscope clamp taken amount is big, can improve operation effect
Rate, the phenomenon that effectively tissue being avoided to be caught broken, good operation effect.
To achieve the above object, the utility model takes following technical proposals：
Novel cavity mirror pincers described in the utility model, including claw beam, are fixed with binding clip, in claw beam in the front end of the claw beam
Rear end be fixed with the handle for controlling the binding clip folding, the binding clip is three-pawl type structure, and it is identical that binding clip includes three structures
Chela, the chela includes the pawl arm for being connected in the claw beam front end and the pawl head that is connected in the pawl arm front end, the pawl
Arc groove is provided on the clamping face of head, when binding clip is engaged, the arc groove on three pawl heads is connected to form a sealing
Gripping chamber；It is slided on three pawl arms and is equipped with snap-gauge, booster frame is provided on the claw beam, the booster frame includes sliding
The dynamic pushing assisted plate being set on the claw beam, on the pushing assisted plate between be arranged at intervals with the support column extended forward, the support
The front end of column is fixedly connected with the snap-gauge.
Resetting spring is both provided between per the two neighboring pawl arm middle and upper part.
Spacing central angle between per the two neighboring pawl arm is 120 °.
When the binding clip is engaged, the gripping chamber shape that the arc groove on three pawl heads is formed is cylindrical, ellipse
Circular or spherical structure.
The utility model advantage is simple in structure, and binding clip uses three-pawl type structure, and the arc groove on binding clip is being engaged
When formed one sealing holding chamber, clamping when slough, lump etc. can be clamped in holding chamber completely, gripping amount
Greatly and caught object can be avoided to occur the phenomenon that being caught broken or dropping in clamping process, improve procedure efficiency, it is ensured that operation
Effect.Booster frame, resetting spring are combined the folding for helping to control binding clip.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of arc groove in Fig. 1.
Fig. 3 is the structure diagram of snap-gauge in Fig. 1.
Specific embodiment
As shown in Figure 1 and Figure 2, novel cavity mirror pincers described in the utility model, including claw beam 1, are connected in the front end of claw beam 1
There is binding clip, the handle 2 of control binding clip folding is fixed in the rear end of claw beam 1, binding clip is three-pawl type structure, and binding clip includes three knots
The identical chela of structure, chela include the pawl arm 3 for being connected in 1 front end of claw beam and the pawl first 4 for being connected in 3 front end of pawl arm, the folder of pawl first 4
It holds and arc groove 5 is provided on face, when binding clip is engaged, the linking of arc groove 5 on three pawls first 4 forms the folder of a sealing
Chamber is taken, gripping chamber is cylindrical structural（Can certainly be ellipsoidal structure or spherical structure）, convenient for storing by gripping object；Such as
It is slided shown in Fig. 1, Fig. 3, on three pawl arms 3 and is equipped with snap-gauge 6, snap-gauge 6 is cyclic structure, is provided with booster frame on claw beam 1, helps
Push bracket includes the pushing assisted plate 7 being slidably located on claw beam 1, and the support column 8 extended forward is arranged at intervals on pushing assisted plate 7, supports
The front end of column 8 is fixedly connected with snap-gauge 6.
During actual manufacture, as shown in Figure 1, Figure 3, the spacing central angle between every two neighboring pawl arm 3 is for 120 ° and per phase
Resetting spring 9 is both provided between adjacent two 3 middle and upper parts of pawl arm.
Binding clip is closed in use, pulling back handle 2, then this hysteroscope is clamped and is inserted into through metal blank pipe in body cavity, to
Binding clip opens during preceding driving handle 2, and the arc groove 5 of binding clip is aligned the gripped objects such as tumour or slough, is shaken hands backward
Handle 2 is closed binding clip, and gripped object is clamped in completely in the holding chamber that three arc grooves 5 are formed, backward clamps this hysteroscope
It is extracted out out of body cavity.
