Specific embodiment
The content of the present invention is described in detail with embodiment with reference to the accompanying drawings of the specification:
It is as shown in figs. 1-7 a kind of scalable puncture outfit with closure function provided by the utility model, it includes puncturing
Sheath 1 and the puncture needle 2 being used cooperatively with puncture sheath 1；
It is as shown in Figs 1-4: the puncture sheath 1 puncture sheath different including puncture sheath head 11 and more than two length
12；Realize that tearing conjunction open connects by tearing conjunction structure open between puncture sheath head 11 and puncture sheath 12；
As illustrated in figs. 5-7: the puncture needle 2 includes handle 21 and punctures core bar 22, punctures 22 tail portion of core bar and extends into
In handle 21 and puncture core bar 22 can be moved forward and backward along 22 central axis direction of core bar is punctured；In handle 21 and puncture between core bar 22
Being additionally provided with makes the relatively-stationary position limiting structure of the two.
In surgical procedure, the puncture sheath 12 of appropriate length and puncture sheath head 11 can be selected right as the case may be
It connects, equally, by being moved forward and backward the length for puncturing the adjustment of core bar 22 and puncturing core bar 22, wait puncture when being of convenient length of core bar 22,
It will be fixed between handle 21 and puncture core bar 22 by position limiting structure.
As shown in Figs 1-4: the conjunction structure of tearing open includes being set to puncture 12 tail end of sheath and vertically arranged a pair of locking
Column 31 is arranged in coordination hole 32 that 11 front end of puncture sheath head is matched with locking column 31 and set on puncture sheath head 11 and passes through
The Bolt with latching action 33 that transverse movement locks puncture sheath 12 and puncture sheath head 11；
As shown in Figure 5: Bolt with latching action 33 includes a pair of of bolt 331, the button 334 for being connected to two bolt tail ends, setting
In the locking fixture block 332 of bolt head end lateral surface and by the reset spring 37 of the reversed pushing tow of bolt, the reset spring 37
Both ends are connected between 11 outer wall of puncture sheath head and button 334, are equipped with inclined-plane A333 in the bottom surface of locking fixture block 332,
The inclined-plane B311 cooperated with inclined-plane A333 is equipped in the top surface of locking column；Locking column 31 is equipped with the lock for limit bolt 331
Determine slot A34.
Usage mode is as follows: when locking column 31 is docked with coordination hole 32, the inclined-plane B311 of locking column top surface and locking block
The inclined-plane A333 of 332 bottom surface of block interacts, and makes 33 transverse shifting of Bolt with latching action and compression reseting spring 37, in lock slots A34
After Bolt with latching action alignment, the rebound of reset spring 37 drives Bolt with latching action 33 to pop up, and Bolt with latching action 33 will be inserted into lock slots A34,
Since bolt head end lateral surface is equipped with locking fixture block 332 in Bolt with latching action 33, locking fixture block 332 rests in lock slots A34, makes
The inside that locking fixture block 332 is stuck in locking column 31 will puncture sheath 12 and the locking connection of puncture sheath head 11；It needs puncture sheath
When pipe 12 and puncture sheath head 11 separate, button 334 is laterally pressed, the 33 inwardly movement of compression reseting spring 37 of Bolt with latching action makes
Locking fixture block 332 exits lock slots A34, and bolt completely disengages lock slots A34 at this time, and the rebound of reset spring 37 drives Bolt with latching action
33 restore home position.
As illustrated in figures 6-10: the position limiting structure includes being arranged in puncture the cross key 41 of 22 tail end of core bar, be set to hand
Mistake is rotated equipped with the cross aisle 42 extended along hand front-rear direction, positioned at 42 front end of cross aisle in handle 21 and with cross aisle 42
The cross recess 43 and stiff spring 44 of position；The puncture core bar 22 keeps puncture core bar 22 logical along cross by the guidance of cross key 41
Road 42 is moved forward and backward, and is punctured and is connected between core bar 22 and handle 21 by stiff spring 44.Make after puncturing the forward movement of core bar 22
44 pairs of puncture core bars 22 of stiff spring apply tractive force backward.
Cross aisle 42 and cross key 41 cooperate, and slide along the longitudinal direction for guiding puncture core bar 22, due to drawing bullet
The presence of spring 44, puncture 22 original state of core bar, which is in, to be pulled back by stiff spring 44 to ultimate attainment state.In use process, need
Core bar 22 will be punctured to stretch forward, when puncture core bar 22 is stretched to cross key 41 and 43 corresponding position of cross recess, by turning
It is dynamic to puncture core bar 22, so that cross key 41 is detached from cross aisle 42 and be located at the front of cross recess 43, in the effect of stiff spring 44
Under, cross key 41, which moves backward, to be fallen into cross recess 43；The distance that the process cross key 41 is advanced exactly punctures the elongation of core bar 22
Process.
The puncture core bar 22 divides to puncture core bar back segment 221 and puncturing core bar leading portion 222, punctures 221 He of core bar back segment
It punctures and is fixedly connected between core bar leading portion 222, be equipped with the pin 51 fixed for 44 end of stiff spring in core bar 22 puncturing.
The mode that is fixedly connected for puncturing core bar back segment 221 and puncturing between core bar leading portion 222 can be using ultrasonic welding, glue buckle
Etc. modes connect.The purpose of 22 segment design of core bar is punctured primarily to whole easy to assembly.
The inner circumferential of the cross recess 43 is equipped with guide rod 45, and the puncture core bar back segment 221 is hollow structure, punctures core bar
Back segment 221 is sheathed on outside guide rod 45 and according to sliding before and after guide rod 45, and 44 both ends of stiff spring are connected to puncture
The hollow structure front end of core bar back segment 221 and the front end of guide rod 45.
As illustrated in figs. 11-14: it further include closure converting unit, the closure converting unit include for puncture sheath
The adapters 61 of 12 docking and it is set to 61 upper end of adapter and for guiding a pair of of guiding tube 62 of sewing needle 7.It used
Cheng Zhong first docks closure converting unit with sheath 12 is punctured, and sewing needle 7, which clamps suture, passes through one of guiding tube 62
Cortex is penetrated from top to bottom, suture is internal by bringing into vitro, then taken out of in vitro from another guiding tube 62 by the end of a thread.
The adapter 61 is equipped with fixture block 63, the lock that the fixture block 63 is equipped with puncture 12 tail end locking column 31 of sheath
Determining slot A34 cooperation connect closure converting unit with sheath 12 is punctured.As long as in use, adapter 61 and puncture sheath 12 is right
It connects, rotates adapter 61 later, fall into fixture block 63 in lock slots A34.
