Description
Technical field
The utility model is related to medical instruments fields, and in particular to a kind of heart card punch.
Background technology
The relatively good method for treating late heart function failure is heart transplant.Operation implantation left ventricle assist blood pump, needs
Quickly get a regular circular hole in left ventricle apex of the heart position.Reach this purpose, conventional method is that cardiac surgeon uses hand
Art knife is cuted out in left ventricle apex of the heart position and cuts out a circular hole.
In surgical procedure, when cardiac surgeon uses scalpel, the arm due to holding scalpel can tremble, and cause to perform the operation
Knife is shaken, and easily causes punching edge irregular（Form zigzag）, while ventricular organization's clast residual is also easily led to, and
Residual tissue is bound to cause thrombus, blocks human body vitals, seriously threatens the postoperative survival of patient.
Utility model content
The utility model is intended to provide a kind of heart card punch, and to solve conventional cardiac punching, punching edge is irregular
Problem.
A kind of heart card punch in this programme, including cylindrical shell are equipped with axocoel, power cavity inside cylindrical shell successively
With energy chamber, partition board is equipped between axocoel and power cavity, the axocoel inner wall is equipped with supporting rack, is rotatably connected to and turns on supporting rack
One end of axis, shaft is equipped with driven tooth, and the other end of shaft is equipped with blade；Motor, the output of motor are equipped in the power cavity
End is equipped with driving tooth, driving tooth and driven tooth engagement；The energy intracavitary is equipped with battery pack, battery pack and motor electric signal phase
Even；One end of the cylindrical shell is equipped with button, and button is connected with battery pack electric signal；The other end spiral shell of the cylindrical shell
Line is connected with conical head, and circular hole is offered on conical head, the disk with conical head coaxial line, the disk and circle are equipped in circular hole
Be formed between hole for blade by gap；Cavity is offered in the shaft, cavity internal clearance is furnished with sleeve, and partition board passes through
The sleeve is fixedly linked with disk；Fixed pin is vertically connected on the disk, the syringe needle of fixed pin is equipped with barb, described
Fixed pin is stretched out by circular hole.
The operation principle of this programme：In use, cardiac surgeon needs punch position according to actual conditions, in heart, it is first
Fixed pin is first inserted into the position, while subsequent cardiac surgeon presses lower button, one hand holds cylindrical shell and keeps it
It stands motionless；And the motor after being powered, it is rotated under the power supply of battery pack, shaft is rotated in company with driven tooth；Due to disk and circle
Be formed between hole for blade by gap, the blade being connected with shaft rotates in gap, and the sickle register of rotation is dirty to be waited for
Punch position is cut, and through-hole can be rapidly got on heart；And part to be punctured on heart, it is inserted into simultaneously by fixed pin
In the fixation of barb, the group at avoidable position to be punctured is swung when being woven in blade cutting, and it is not in not advise then to punch edge
Then the phenomenon that.
The advantageous effect of this programme：Using the present apparatus, take the lead in fixing punch position by fixed pin, then to rotate
Blade arbitrarily swung on heart, it is ensured that punch the round and smooth of edge；And fixed pin can prevent residual tissue from falling, and can have
Effect avoids the generation of thrombus.
Further, the outer wall of the cylindrical shell is arranged with Anti-slip cover.In use, cardiac surgeon can be with sterilizing hand
Set increases the frictional force between Anti-slip cover and antimicrobial gloves, card punch is avoided to slide by Anti-slip cover.
Further, display screen is installed, display screen is connected with battery pack electric signal on the button.It can be with by display screen
The remaining capacity for directly observing battery pack, can avoid in drill process, due to punching failure caused by not enough power supply.
Further, LED light is installed, LED light is connect by the battery pack with button electric signal on the conical head.Increase
The brightness of big heart region, it is ensured that cardiac surgeon can clearly observe punching effect.
Description of the drawings
Fig. 1 is a kind of overall structure figure of heart card punch of the utility model.
Specific implementation mode
The utility model is described in further detail below by specific implementation mode：
