Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical solution of the utility model is described further.
A kind of nose tissue punch forceps, including fixed handle 1, flexible handle 2, sleeve 3, the first claw beam 41, adjusting block 42,
Two claw beams 43, fixed clamp 5, active clamp 6, connecting rod 7 and safety buckle 8,
The fixed handle 1 is articulated with a bit with flexible handle 2, and flexible handle 2 can be around hinge joint relative to fixed handle 1
Rotation,
The sleeve 3 is hollow cylindrical member, and is set on fixed handle 1,
The fixed handle 1 opens up first through hole 11,
First claw beam 41 protrudes into first through hole 11 through in the inner hole of sleeve 3,
The adjusting block 42 is set in first through hole 11, and one end is connect with 41 left hand thread of the first claw beam, the other end with
The connection of second claw beam, 43 right-handed thread,
Described second claw beam, 43 one end is protruded into first through hole 11, and hemisphere jut 431 is formed on the other end,
The cross section of first claw beam 41 and the second claw beam 43 be irregular shape, can in first through hole 11 edge
It is moved axially, and cannot axially be rotated around it,
It is formed with spherical sliding slot 21 compatible with hemisphere jut 431 on the flexible handle 2 and accommodates the second claw beam 43
Straight 22,
The fixed clamp 5 is set on sleeve 3, and the active clamp 6 is rotatablely connected with fixed clamp 5, the connecting rod 7
One end and active clamp 6 are hinged, and the other end and the first claw beam 41 are hinged,
Described 8 one end of safety buckle and fixed handle 1 are rotatablely connected, and are formed with long hole 81 and small sircle hole 82, institute on the other end
Small sircle hole 82 is stated to be connected to long hole 81,
Pin shaft 23 compatible with small sircle hole 82 is provided on the flexible handle 2.
As shown in Figure 1, being the structure principle chart of nose tissue punch forceps, by flexible handle 2 around the hinge of itself and fixed handle 1
The rotation of contact pulls connecting rod 7 to drive the second claw beam 43, adjusting block 42 and the first claw beam 41, as shown in fig. 7, final turn
The rotating down relative to fixed clamp 5 of chemical conversion active clamp 6, completes the resection operation of nose tissue.In drawing process
Two claw beams 43 are because in drawing process, the angle change of flexible handle 2, as shown in fig. 6, hemisphere jut 431 can be in spherical shape
The excision process of opposite up and down motion and rotation to cooperate completion entire in sliding slot 21.
The maloperation of flexible handle in resection operation in order to prevent, as shown in figure 5, safety buckle 8, which just plays, to be prevented from missing
The effect of operation.When before excision, generally require to find suitable position, and the excision work under last be often the time most
Short, the time overwhelming majority of an operation is in position and the angle for finding excision.In the process, safety buckle 8 should be made
State in such as Fig. 5.At this point, small sircle hole 82 is adapted with pin shaft 23, engaging is close, and flexible handle 2 is relative to fixed hand
Therefore the rotational freedom of handle 1 is restricted.After searching out suitable position, at this point, being rotated up safety buckle 8 makes pin shaft
23 slide into long hole 81, and for You Tuzhong it is found that the size of long hole 81 is greater than the size of pin shaft 23, pin shaft 23 can be in long hole 81
It is free to slide.Then, flexible handle 2 can be rotated relative to fixed handle 1 at this time, and pressing flexible handle 2 can complete nose group
The resection operation knitted.By the setting of safety buckle 8, limit the freedom degree of the flexible handle 2 in the operating process of operation, no
Can tamper or malfunction and patient is damaged.
In addition, generally requiring to adjust work according to the size of the tissue of different excisions during actual operation
The size of dynamic clamp 6 and the angle of fixed clamp 5.At this time the angle can be adjusted by rotation adjusting block 42.By institute
The cross section for stating the first claw beam 41 and the second claw beam 43 is irregular shape, can axially be moved in first through hole 11 along it
It is dynamic, and cannot axially be rotated around it, it is conventional, it can be the cross section of rectangle or ellipse etc..As shown in figure 4, adjusting block 42
By the connection of one end and 41 left hand thread of the first claw beam, one end is connect with 43 right-handed thread of the second claw beam, a direction rotation
Adjusting block 42, which can further, the first claw beam 41 or releases the first claw beam 41 to adjust the folder of active clamp 6 and fixed clamp 5
The size at angle.It adjusts adjusting block 42 to need to remove a block of material at the through-hole 11 of fixed handle 1, makes to be set to inside through-hole 11
Adjusting block 42 be exposed to outside, by hand rotation or rubbing can be carried out adjusting.In addition, being adjusted there are also a kind of mode
The angle, exactly opens up more dry small sircle holes 82 on described 8 one end of safety buckle, selects engaging to enter by pin shaft 23 different
Small sircle hole 82 adjusts the angle of flexible handle 2, is finally reached the size of the angle of adjustment active clamp 6 and fixed clamp 5
Purpose.
The fixed clamp 5 is circular ring shape or oval ring, and upside has the first cutting blade 51, the adjustable clamp
Folder 6 has the second cutting blade 61 for circle compatible with fixed clamp 5 or ellipse, downside.
As shown in figure 8, the extension size of the second cutting blade 61 of active clamp 6 is less than in the first cutting blade 51
Size is enclosed, the first cutting blade 51 and the second cutting blade 61 are stung and cut, and generate shear force and cut off nose tissue.Due to this round or ellipse
The setting of circular cutter head, cutting blade be not it is sharp, patient's nasal cavity will not be stabbed, safety is good.
It will be appreciated that the embodiments of the present invention while there has been shown and described that, for the common skill of this field
For art personnel, it is possible to understand that can be carried out to these embodiments in the case where not departing from the principles of the present invention and spirit
A variety of change, modification, replacement and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
