A kind of cardiac operation Myocardium protecting device

Technical field

The utility model relates to department of cardiac surgery's equipment correlative technology field, specifically a kind of cardiac operation is protected with cardiac muscle Protection unit.

Background technique

Department of cardiac surgery is a younger subject in each branch of surgical field, mainly with operative treatment heart disease, such as Heart pass art, congenital heart disease operation, prosthetic valve replacement etc., micro-wound surgical operation refers to wound as small as possible, comes Operation required for completing achievees the purpose that treatment disease, and with the development of medical science, minimal invasive techniques are in cardiac surgery field Application it is also more and more extensive, keep department of cardiac surgery smaller and smaller towards wound, the increasing direction of safety is developed.

In cardiac operation, myocardial preservation is particularly important, but traditional Myocardium protecting device is fixed Locating effect is bad, not can be carried out the real-time adjustment that heart inserts the insertion depth of conduit, narrow scope of application, and conventional cardiac is inserted and led Pipe is inconvenient when carrying out position placement to be easy to fall off the problem of skewing, and the safety of cardiac operation is greatly diminished, The manual operation difficulty for increasing attending physician in myocardium protecting liquid flowing is also easy to that backflow phenomena occurs, more hinder Openheart surgery is gone on smoothly, and needs to carry out the solution of problem.

Utility model content

In order to solve the problems in the existing technology, the purpose of the utility model is to provide a kind of cardiac operation use Myocardium protecting device.

In order to achieve the above-mentioned object of the invention, the utility model uses technical solution as described below:

A kind of cardiac operation Myocardium protecting device, including myocardium protecting liquid storage tanks, the myocardium protecting liquid storage It puts and integrally has additional medical fluid buffer chamber at the upper left position of tank, pass through at the downside wall right positions of medical fluid buffer chamber The unidirectional liquid feed valve installation settings of No.1 has drawing liquid conduit, and the tube body of drawing liquid conduit state in a vertical shape is arranged and its tube body is downwardly into The chamber bottom of myocardium protecting liquid storage tanks passes through No. two unidirectional tapping valves at the downside wall leftward position of medical fluid buffer chamber Installation settings has infusion tube, and the tube body bottom end of the infusion tube is integrally attached to heart and inserts on conduit, in medical fluid cushion chamber Also sealing is provided with and communicated with negative pressure expulsion bladder in the side wall of room, and the heart inserts adaptation on the tube body of conduit and is arranged with a cunning Dynamic positioning sleeve, sliding positioning sleeve carry out the position adjustment that heart plugs in conduit by the No.1 fastening bolt of side, and the sliding is fixed It is also fixedly connected by support telescopic bar on the left wall face of position set and is provided with absorption locator, support telescopic bar passes through the two of side Number fastening bolt carries out length adjustment, and the absorption locator includes mutually matched skin adsorption seat and groove by press button, The pedestal center of skin adsorption seat is through with a negative-pressure adsorption channel, the top passageway mouth circle in the negative-pressure adsorption channel At week, lower ring limit block, the surface of the lower ring limit block, respective slot pressing are provided on corresponding skin adsorption seat It is provided with ring limit block on the inner wall of button, the state setting in a vertical shape between upper ring limit block and lower ring limit block Have a large size elastic compression spring, at the left and right sides position of the large size elastic compression spring, respective slot by press button with State installation settings also in a vertical shape has flexible guide rod between skin adsorption seat, the position at left and right sides of the top of skin adsorption seat Place is also integrally extended outward respectively thumb buckle.

Further, Liquid level scale line is provided on the front face of the myocardium protecting liquid storage tanks.

Further, protection liquid adding mouth is come in myocardium protecting liquid storage tanks.

Further, heart inserts the tube body state setting in a vertical shape of conduit and its tube body bottom end is equipped with liquid medicine applying head.

Due to the adoption of the above technical scheme, the utility model has following superiority:

It is main after the utility model in the structure basis of traditional Myocardium protecting device by having additional an absorption locator It controls doctor and before the operation of patient's myocardial preservation, is contradicted on the lower surface of thumb buckle with index finger middle finger between, use thumb Apply a downward pressure by press button to groove, groove becomes by relative position is generated between press button and skin adsorption seat immediately Change, large size elastic compression spring generates physics flexible deformation to be shortened by compression, the upper ring limit block of setting and lower annular stop Block can avoid large size elastic compression spring and shift, until flexible guide rod stops after being compressed to the limit, attending physician with Locator will entirely be adsorbed to be placed around on skin according to different patient's heart status requirements, unclamp groove after being adjacent to skin By press button, large size elastic compression spring jacks up upwards under the elastic reset power effect that itself is compressed, and then logical in negative-pressure adsorption Negative pressure is generated in road, entire absorption locator can be fixed on patient skin by this negative pressure, then the support telescopic by adding Bar adjusts the length in horizontal direction, the insertion depth that heart plugs in conduit is adjusted by sliding positioning sleeve, to realize medical fluid Treatment head adjusts demand in the position in different patient's heart affected parts, and the scope of application is effectively expanded, and stationary positioned effect is good, very well Solve the problems, such as conventional cardiac plug in conduit inconvenient be easy to fall off when carrying out position placement skew, for it is subsequent cardiac muscle guarantor The accurate dispensing of shield liquid provides the foundation, it is ensured that the safety of cardiac operation reduces the manual operation of attending physician Difficulty；And the unidirectional liquid feed valve of the No.1 added and No. two unidirectional tapping valves ensure that the flowing one-way of myocardium protecting liquid, keep away Exempt from that backflow phenomena occurs, has further ensured going on smoothly for openheart surgery.
