Specific embodiment
In order to which those skilled in the art is made to more fully understand the technical solution of the utility model, below in conjunction with attached drawing pair
The utility model is further detailed.
It is shown in Figure 1；
A kind of cardiac muscle biopsy device of the utility model, including：
Blade 1, blade 1 is cylindrical, and spiral cutting edge 4 is provided on columned blade 1；
Cutter shaft 2, the axial direction of blade 1 along blade 1 offer threaded hole, and cutter shaft 2 is threadedly connected in threaded hole；
The upper and lower ends of cutter shaft 2 are at least partly stretched out outside blade 1, and the part that cutter shaft 2 is placed in outside blade 1 is respectively provided with
There is scale；The front end of cutter shaft 2 is abutment end 10, and the abutment end 10 of cutter shaft 2 is posted by ventricle.
Specifically, a kind of cardiac muscle biopsy device disclosed in the utility model, mainly includes a blade 1 similar to bolt,
Spiral cutting edge 4 is provided on blade 1, such medical staff in operation, can rotate blade 1, using spiral cutting edge 4 to cardiac muscle
Tissue is cut, and mode of operation is simple.In addition, the present embodiment is provided with a cutter shaft 2, cutter shaft 2 also at the axis of blade 1
Front end primarily serve supporting role, that is, in treatment, the front end of cutter shaft 2 is needed against ventricular septum, then medical care
Personnel rotate again blade 1 carry out cutting operation, and cutting when, using the scale on cutter shaft 2 can facilitate observation blade 1 into
To amount, the amount of feeding is controlled, avoids breakdown ventricular septum.In addition, the scale of 2 front end of cutter shaft is mainly to play calibration, contraposition, i.e.,
Before use, the both ends of the surface of blade 1 are needed to realize and are fixed at a certain scale, then can be just continuing with.And 2 rear end of cutter shaft
Scale is exactly to observe the amount of feeding in order to facilitate medical staff.
Preferably, the end set of rear end of the blade 1 far from cutter shaft 2 has control head 3 in the present embodiment, by controlling first 3
Blade 1 is driven to rotate.It is provided with protrusion in the rear end of blade 1, protrusion is the control head 3 in the present embodiment, during operation, medical care people
Member can hold control head 3, and rotate blade 1 to a direction, so as to fulfill cutting.Therefore, control head 3 addition be mainly
It is operated in order to facilitate medical staff.
Preferably, the scale on part that cutter shaft 2 is placed in outside blade 1 is 0-2mm, and the both ends of the surface of blade 1 are placed in
At 0mm.The position of 1 both ends of the surface of range and blade of scale is disclosed in the present embodiment, since ventricular septum is very weak,
If the amount of feeding is excessive, it is easy to puncture, and be summarized for a long time according to clinical medicine, as long as the amount of feeding is less than 2mm, it is possible to avoid
Breakdown, therefore, the present embodiment provide the range of scale in 0-2mm, and 1 both ends of the surface of blade are placed at 0mm scales and are
Facilitate observation.
In order to realize that the range of feeds is in 0-2mm in said program, need to be placed on the spiral cutting edge 4 of front end most
High point is with being located at same level at the 2mm of scale for being placed in 2 front end of cutter shaft.In this way in cutting, blade 1 travels forward, that
The peak of the spiral cutting edge 4 of front end can only also advance forward 2mm, it is ensured that the amount of feeding is in prescribed limit.
In addition, the cardiac muscular tissue cut needs to be collected, one for subsequent detection, and therefore, the present embodiment is in blade 1
Outside be provided with cardiac muscular tissue's collection device.And cardiac muscular tissue's collection device is sheath 5, and for the realization of device,
In, blade 1 is required to across sheath 5, and the connection mode of 1 rear end of blade and sheath 5 can be many kinds, belong to this field
What technical staff was readily apparent that, it no longer illustrates here.
It is furthermore preferred that the inside of sheath 5 has partition board 6 in the present embodiment, partition board 6 divides sheath 5 for two parts, respectively
Collecting chamber 7 and operating cavity 8, blade 1 are movably installed in operating cavity 8.And a block 9, block 9 are provided in the inside of partition board 6
It is placed in the front of any spiral cutting edge 4 of the spiral cutting edge 4 except front end.Collecting chamber 7 is cut when blade 1 rearward moves
The cardiac muscular tissue cut can be collected after cutting, and when blade 1 travels forward, the block 9 on partition board 6 again can be with
Spiral cutting edge 4 is stopped, it is excessive and injured patient to avoid operating unskilled medical staff's amount of feeding, it is ensured that patient
Safety.
In the above-mentioned technical solutions, a kind of cardiac muscle biopsy device provided by the utility model, passes through the spiral cutting edge of blade 1
4 can when rotated cut surrounding myocardium tissue, meanwhile, it can be intuitively using the scale medical staff on cutter shaft 2
Understand the depth that blade enters, avoid breakdown ventricular septum, controllability is high, it is ensured that the safety of patient.
Above certain exemplary embodiments that the utility model is only described by way of explanation, undoubtedly, for
Those of ordinary skill in the art, can be with a variety of different in the case of the spirit and scope without departing from the utility model
Mode is modified described embodiment.Therefore, above-mentioned attached drawing and description are regarded as illustrative in nature, and should not be construed as
Limitation to the utility model claims protection domain.
