Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a myocardial tissue measuring device. Background Art

[0002] Hypertrophic cardiomyopathy is characterized by myocardial hypertrophy. According to whether there is obstruction in the left ventricular outflow tract, it can be divided into obstructive and non-obstructive hypertrophic cardiomyopathy. Idiopathic hypertrophic subaortic stenosis refers to the case where asymmetric ventricular septal hypertrophy causes subaortic stenosis of the aortic valve.

[0003] When treating hypertrophic cardiomyopathy, it is necessary to scrape and remove the redundant myocardial tissue. Therefore, it is necessary to clarify the thickness of the redundant myocardial tissue before the operation. The existing technology generally uses X-ray technology to photograph the ventricle, and judges the thickness of the myocardial tissue based on the X-ray photo and the feeling of the doctor's hand touch during the operation. The existing technology highly depends on the doctor's experience to judge the thickness of the myocardial tissue, and there is great uncertainty. Once the thickness of the myocardial tissue is misjudged, it will cause incomplete resection or excessive resection. Incomplete resection will cause the adverse consequence of the risk of secondary surgery, and excessive resection will cause the adverse consequence of too thin myocardium.

[0018] Embodiment 1

[0019] A myocardial tissue measuring device, as Figure 1 shown, includes: a first connecting rod 1 and a second connecting rod 2 rotatably connected through a rotating connecting device 3. The first connecting rod 1 includes a first rod body 101, and the second connecting rod 2 includes a second rod body 201.

[0020] One end of the first rod body 101 is provided with a first measuring head 102, and the other end is provided with a first handle 103. The same-side end of the second rod body 201 as the first measuring head 102 is provided with a second measuring head 202, and the same-side end as the first handle 103 is provided with a second handle 203. The first measuring head 102 and the second measuring head 202 are arranged facing each other.

[0021] A measuring device 4 is provided between the first connecting rod 1 and the second connecting rod 2. The measuring device 4 includes: a measuring scale 401 fixed to one of the first rod body 101 or the second rod body 201, and an indicator 405 fixed to the other of the first rod body 101 or the second rod body 201. The indicator 405 rotates along the measuring scale 401 as the first connecting rod 1 and the second connecting rod 2 rotate. Figure 1 and Figure 2 shown, the measuring scale 401 is fixed to the second rod body 201, and the indicator 405 is fixed to the first rod body 101.

[0022] The usage process of this device is as follows: First, insert one end of the first measuring head 102 and the second measuring head 202 into the cardiac surgery opening and extend it to the ventricular myocardial tissue. Then, the doctor controls the first handle 103 and the second handle 203, and through the first rod body 101 and the second rod body 201, the first measuring head 102 and the second measuring head 202 are opened based on the rotational connection of the rotating connecting device 3, and the rotation method is similar to that of scissors. After that, the doctor presses the first measuring head 102 and the second measuring head 202 against both sides of the ventricular myocardium and slides along the myocardium. At this time, when the first measuring head 102 and / or the second measuring head 202 slide over the protruding redundant myocardial tissue, it will force the first measuring head 102 and the second measuring head 202 to open abnormally, and through the first rod body 101 and the second rod body 201, the indicator 405 is displaced relative to the measuring scale 401, so that the change value of the abnormally protruding redundant myocardial tissue is displayed on the measuring scale 401. The doctor can know the basic size of the protruding redundant myocardial tissue according to the change value of the abnormally protruding redundant myocardial tissue and judge the thickness of the myocardial tissue to be cut off in the subsequent surgery.

[0023] Embodiment 2

[0024] Based on the myocardial tissue measuring device of the above embodiment, as Figure 1As shown, both the first measuring head 102 and the second measuring head 202 are arranged as circular arc protrusions, and the arc tops face each other. This arrangement enables the first connecting rod 1 and the second connecting rod 2 to open more smoothly when the first measuring head 102 and the second measuring head 202 slide and encounter abnormally protruding redundant myocardial tissue.

[0025] Embodiment 3

[0026] For the myocardial tissue measuring device based on the above embodiments, as Figure 1 shown, the first connecting rod 1 and the second connecting rod 2 are arranged in an up-and-down staggered manner, and the rotational connection device 3 is a rotating shaft connecting the first connecting rod 1 and the second connecting rod 2. This arrangement has a relatively simple structure and is mainly applicable when the first rod body 101 and the second rod body 201 are in a straight rod structure.

[0027] Embodiment 4

[0028] For the myocardial tissue measuring device based on the above embodiments, as Figure 2 shown, the measuring scale 401 is arranged in a horizontal circular arc shape and is fixed to one of the first rod body 101 or the second rod body 201 through the first support column 402, as Figure 2 shown for the second rod body 201. The pointer of the indicator 405 is fixedly arranged and is directed towards the scale part 404 of the measuring scale 401, and is fixed to the other one of the first rod body 101 or the second rod body 201 through the second support column 407, as Figure 2 shown for the first rod body 101.

[0029] A long through hole 403 with the same arc structure is provided on the measuring scale 401; the indicator 405 is located on the top side of the long through hole 403 and is fixedly connected to the second support column 407 located at the bottom side of the long through hole 403 through the indicator connecting column 406 passing through the long through hole 403.

[0030] The measuring scale 401 is marked with spacing values corresponding to the spacing between the first measuring head 102 and the second measuring head 202 along the long through hole 403 on the side of the pointer of the indicator 405.

[0031] This arrangement enables the moving distance of the indicator 405 relative to the measuring scale 401 to have a fixed specific proportional relationship with the moving distance of the first measuring head 102 and the second measuring head 202, so that the spacing values marked on the measuring scale 401 change in an equidistant manner, which is conducive to accurately marking the spacing values.

[0032] The setting of the pointer of the indicator 405 makes the function of indicating the spacing value more obvious and accurate.

[0033] Inspired by the above-described ideal embodiments of the present utility model, through the above description, relevant staff can completely make various changes, combinations, and modifications within the scope not deviating from the technical idea of the present utility model. The technical scope of the present utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
