Embodiment
The embodiment of the present invention is described further below in conjunction with the accompanying drawings.
As shown in figs. 1-7, the present invention is achieved in that the minimally invasive haemostatic clamp convenient for disassembly and assembly includes being rotatably connected on
Together determine handle 1 and fixed handle 2, fixed handle 2 passes through drive connection piece 5 and the one end for extending into the steel wire rope 7 determined in handle 1
It is drivingly connected, the other end of the steel wire rope 7 is drivingly connected with the dynamic pincers 9 being rotatably connected on fixed pincers 8；It is described to determine 1 He of handle
The clamping force adjusting mechanism 4 of rack structure is equipped between fixed handle 2, and determines to be additionally provided between handle 1 and fixed handle 2 to drive and determines hand
The shrapnel component 3 that handle 1 and fixed handle 2 open；It is structurally characterized in that steel wire rope 7 determines the steel wire rope that is slidably connected in handle 1 with being located at
Connecting rod 12 is connected, and the stay rod pin 13 positioned at 5 one end of drive connection piece is connected in steel wire rope connecting rod 12, drive connection piece 5
The other end is rotatablely connected with fixed handle 2, and is provided between drive connection piece 5 and fixed handle 2 and is made 13 clamping steel wire rope of stay rod pin
The torque spring 10 of connecting rod 12；The haemostatic clamp apparatus in its natural state, determines the work of handle 1 and fixed handle 2 in shrapnel component 3
With lower holding open configuration, when needing work, it is only necessary to hold and determine handle 1 and fixed handle 2 applies external force F1, as shown in figure 3,
The drive drive connection of fixed handle 2 piece 5 moves, which will drive dynamic pincers 9 with determining by 7 tractive force F2 of steel wire rope
The occlusion of pincers 8, achievees the purpose that jaw steps up, and so as to fulfill clamping, when moving pincers 9 and pincers 8 reaching suitable chucking power F3 surely, leads to
The relative position that control clamping force adjusting mechanism 4 determines handle 1 and fixed handle 2 is crossed, at this moment user need not just be continuously applied
External force, which can keep constant reliable chucking power, simple to operate, and structure is also more reliable and practical；In order to just
In dismounting, drive connection piece 5 can be connected and fixed conveniently by stay rod pin 13 and steel wire rope connecting rod 12, when needing dismounting,
As long as releasing the interface arrangment, steel wire rope connecting rod 12 will depart from the connection of drive connection piece 5, in order to fixed pincers 8, dynamic pincers 9
It is easy to clean and steel wire rope 7 is from determining to dismantle on handle 1；And torque spring 10 then causes drive connection piece 5 in the feelings of no external force
The connection structure with steel wire rope connecting rod 12, the reliability of holding structure are kept under condition.
In order to ensure the convenience of the transmission of power and fixed disassembly, the present invention is also to steel wire rope 7 and the connection for determining handle 1
Design is optimized in structure, and in the specific implementation, the steel wire rope connecting rod 12 passes through screw thread with one end that steel wire rope 7 is connected
Component, which is installed on, to be determined on handle 1, and threaded components include the locking nut 11 with determining the cooperation of 1 end thread of handle, locking nut 11
Fixed between steel wire rope connecting rod 12 by connecting pin 14, the steel wire rope connecting rod 12 is equipped with what is coordinated with stay rod pin 13
N fonts buckling groove 1201, as long as so drive connection piece 5 is in 10 ineffective power of torque spring, stay rod pin 13 will be from card
Access slot 1201 departs from；As shown in Figure 6 and Figure 7, when needing to dismantle jaw, the first step, it is only necessary to press biography with the power in F4 directions
Connection sheet 5 is moved to overcome the torsion of torque spring 10, at this moment the stay rod pin 13 on drive connection piece 5 will depart from steel wire rope connection
Buckle on bar 12, second step, wherein determining handle 1 with locking nut 11 using being threadedly coupled, locking nut 11 connects with steel wire rope
Extension bar 12 is fixed using connecting pin 14, passes through the screw action of F5, you can depart from locking nut 11 and determine handle 1, so as to drive
Steel wire rope connecting rod 12 departs from together determines handle 1, reaches the function of dismounting jaw.
Another key structure of the present invention is clamping force adjusting mechanism 4, its adjusting for lasting chucking power, control
Fixture has the characteristics of easy to operate, precision is reliable, in the specific implementation, the clamping force adjusting mechanism 4 include wrench assembly with
And adjusting part is engaged with being connected to the rack determined between handle 1 and fixed handle 2, the wrench assembly engages adjusting group with rack
Part control connection；For the feedback dynamics and reliability of the operation control that ensure to use, the wrench assembly include spanner 401 with
And it is fixed on the spanner shrapnel 402 on fixed handle 2；The rack engagement adjusting part includes the work being drivingly connected with spanner 401
Moving teeth button 403 and being fixed on determines buckleing 403 with movable teeth and engage the stationary racks 404 coordinated, spanner shrapnel 402 on handle 1
With the elastic force for making movable teeth button 403 engage with stationary rack 404 to coordinate；It can so allow user using spanner shrapnel 402
Spanner 401 is perceived, and under the action of spanner shrapnel 402 so that spanner 401, which has, is applied to holding for rack engagement adjusting part
Continuous pressure, makes it keep joggleword state, avoids accidental release.
Its operation principle is such, under general state, movable teeth button 403 by the elastic force of spanner shrapnel 402 make its with
Stationary rack 404 engages, and plays the effect of jaw anticreep, and causes dynamic pincers 9 and pincers 8 surely determining handle 1 and fixed handle 2
Lasting grip force is generated under effect, reaches barrier effect；Likewise, when needing to open jaw, need to only the power of F6 be used gently
Spanner 401 is depressed, movable teeth button 403 is swung in the direction of arrows, that is, departs from the engagement of stationary rack 404, so that determining handle 1
Flicked with fixed handle 2 under the elastic force effect of shrapnel component 3, reach the effect for unclamping jaw；So engaged by adjusting gear rack
Position, under the band for controlling chucking power, by rational deployment tooth density, it can be achieved that the accurate adjustment control of clamping force；Specific
During implementation, the part of the movable teeth button 403 and stationary rack 404 with pinion rack is arcuate structure, so that is nibbled
Close structure more to smooth out, fixed beneficial to occlusion.
In order to improve the convenience of operation and reliability, the present invention is also optimized the other details structure of haemostatic clamp
Design, the shrapnel component 3 include the first shrapnel 301 and the second shrapnel 302, the lower end of the first shrapnel 301 and the second shrapnel 302
Lower end be separately fixed at and fixed handle 2 and determine on handle 1, the upper end of the upper end of the first shrapnel 301 and the second shrapnel 302 is overlapped on
Together；Such first shrapnel, 301 and second shrapnel 302 is beneficial to assembling, and can interact with the active force of user, is formed
Suitable feedback dynamics, improves the feel of operation；The minimally invasive haemostatic clamp further includes the support component 6 being looped around outside steel wire rope 7, should
The flat ball unit that support component 6 is set in outside steel wire rope 7 by several forms, which ensure that structural support is strong
Degree, but permission jaw easily changes angle and the direction of bending, and the reliability and convenience of operation are more preferable.
The present invention is compared with traditional instruments, and disassembly, cleaning are convenient, and easy to operate, not cumbersome, it can be on a kind of handle
Different types of jaw can be filled to meet the use of medical staff, reached multi-edged function, disassembling can also cause
Instrument cleaning is more thorough.
