Fig. 2 is the partial enlarged drawing for expanding head；
Fig. 3 is the partial enlarged drawing of position-limit mechanism.
Specific embodiment
Specific embodiment of the present utility model is illustrated below in conjunction with accompanying drawing.
The structural representation of the blood vessel cutout extension device that Fig. 1 is provided for the utility model.
As shown in figure 1, blood vessel cutout extension device (hereinafter referred to as extension fixture) 10 includes handle 11, handle 12, connection
Bar 13, connecting rod 14, angular surveying disk 15, position-limit mechanism 16, expansion first 17 and expansion first 18.Handle 11 and the end of handle 12
Gripper rings are provided with, by stud connection, angular surveying disk 15 is arranged on the hinge for connecting rod 13 and the middle part of connecting rod 14.
Fig. 2 is the partial enlarged drawing for expanding head.
As shown in Fig. 2 expansion first 17 and expansion first 18 are separately mounted to connecting rod 13 and connecting rod 14 away from the one of handle
On end, in hollow semi-conical.Therefore, when extension fixture 10 closes up, expansion first 17 and expansion first 18 are contacted, and are formed complete
Open circles frustum.Additionally, the edge of expansion first 17 and expansion first 18 slightly protrudes from connecting rod 13 and connecting rod 14, close device 10
When holding together, a fixed gap is maintained between connecting rod 13 and connecting rod 14.
In the present embodiment, expansion first 17 and the small one end of first 18 diameter of expansion have smooth arc surface；Expansion first 17 and
The height of expansion first 18 is 0.5cm~2.0cm；In expansion first 17 and expansion first 18, the Zhou Changwei 20mm of the small one end of diameter~
28mm, the Zhou Changwei 24mm~32mm of the big one end of diameter.
Fig. 3 is the partial enlarged drawing of position-limit mechanism.
As shown in figures 1 and 3, position-limit mechanism 16 includes the first positive stop strip 161, the second positive stop strip 162 and spring 163.
First positive stop strip 161 is arranged on the bottom of connecting rod 13, and the second positive stop strip 162 is arranged on the bottom of connecting rod 14,
The two ends of spring 163 are separately mounted in connecting rod 13 and connecting rod 14.
Spring 163 is extension spring, is in compressive state when external force is not received；When extension fixture 10 is opened, spring 163 is drawn
Stretch, generation forces the pulling force that extension fixture 10 closes up.
As shown in figure 3, being equipped with size identical limiting tooth on the first positive stop strip 161 and the second positive stop strip 162.These limits
Position tooth towards offside, i.e., limiting tooth the second positive stop strip 162 of direction, on the first positive stop strip 161, on the second positive stop strip 162
Limiting tooth the first positive stop strip 161 of direction.When such structure opens extension fixture 10, the first positive stop strip 161 and second is spacing
Limiting tooth on bar 162 can be engaged, and the two is blocked mutually, after opening extension fixture 10, spring 163 can be overcome to produce
Pulling force, be maintained at the state of opening.
The occupation mode of extension fixture 10 of the present utility model is illustrated below in conjunction with drawings and Examples.
When using, the gripper rings on handle 13 and handle 14 are held, keep extension fixture 10 in closed configuration, head will be expanded
17 and expand it is first 18 formed the frustums of a cone insertion blood vessel otch, then open extension fixture 10, and adjust the first positive stop strip 161 and
The position of the second positive stop strip 162, engages limiting tooth, and the first positive stop strip 161 and the second positive stop strip 162 are blocked mutually, so that
Extension fixture 10 is maintained at the state of opening, and the angle that connecting rod 13 and connecting rod 14 are opened is read using angular surveying disk 15,
Suitable open angle is adjusted such that it is able to recording angular reading or according to conventional record.After open angle adjustment is finished, from
Inserted the catheter into the space formed in the middle of expansion first 17 and expansion first 18, after conduit is inserted into appropriate location, adjustment first is limited
The position of the position positive stop strip 162 of bar 161 and second unclamps both, and extension fixture 10 is taken out from blood vessel otch.Then, one can be entered
Step opens extension fixture, conduit is taken off from extension fixture 10, and extension fixture 10 can carry out other operations after removing.
Embodiment is acted on and effect
The extension fixture that the present embodiment is provided, because two expansion heads are in the shape of semicircular platforms, therefore this two expansions
It is smaller that head closes up rear point diameter, can be more easily inserted into blood vessel otch, and expand blood vessel otch after extension fixture opening
.Expansion head for hollow, therefore conduit can from expansion capitiform into space at insert blood vessel, make catheter insertion operations be more easy into
OK；Expanding small one end of the diameter of head (one end of insertion blood vessel otch when operating) has smooth arc surface, can avoid
To the damage of vascular wall during insertion operation.
In the present embodiment, position-limit mechanism includes the first positive stop strip, the second positive stop strip and spring, can beat extension fixture
The state opened is kept after opening, makes subsequent operation be more easy to carry out；Angular surveying disk is accompanied with hinge, can be by reading angular
The angle that the reading control device of Measuring plate opens, while the reading can also be recorded as later operation provides reference number
According to.
