Description

Under thoracoscope, Pulmonary Vascular is separated suction pump
Technical field
The present invention relates to a kind of medical apparatus and instruments, the especially a kind of and matching used suction pump of thoracoscope, specifically under a kind of thoracoscope, Pulmonary Vascular is separated suction pump.
Background technology
At present, Minimally Invasive Surgery is a kind of novel low invasive procedures, and is subject to the increasing of the doctor of patient, especially to carry out in thoracic surgery a kind of development trend especially.Owing to not only needing to excise tissue in thoracoscopic operation process, also need to carry out Pulmonary Vascular separation, vacuum extractor general in tissue ablation process is difficult to the requirement meeting blood vessel separation, especially existing vacuum extractor does not possess auxiliary separation function, need separately to join corresponding operating theater instruments, and the impact of the operating theater instruments quantity hands opening that thoracoscope is once inserted, quantity is very limited, this just causes often to change apparatus in operation process, cause the tired lock of operation, the series of problems such as inefficiency, therefore develop and a kind ofly can carry out attraction to the blood produced in blood vessel separation process and little tissue and excrete, the suction pump carrying out being separated can be assisted again, reduce operating theater instruments kind very important.
Summary of the invention
The object of the invention is to be separated for Pulmonary Vascular under existing thoracoscope the problem affecting procedure efficiency because lacking desirable vacuum extractor, designing and a kind ofly can adsorb and can help Pulmonary Vascular separation suction pump under the thoracoscope that blood vessel is separated.
Technical scheme of the present invention is:
Under a kind of thoracoscope, Pulmonary Vascular is separated suction pump, it is characterized in that it forms primarily of negative pressure connector portions 1, portion of the handle 2, suction catheter portion 3 and sucking head 4 successively overall being connected, their inside forms through vacuum suction passage, the surrounding of described sucking head 4 is provided with multiple vacuum suction hole 5, described suction catheter portion 3 is made up of the first straight line pipeline section 301 of space intersection and the second straight line pipeline section 301, their axis horizontal projection angle α is between 140-170 degree, and the first straightway is connected with portion of the handle 2 coaxial line; Described sucking head 4 is connected with the second direct line 302, and the angle β between both axial lines is between 135-160 degree.
Described sucking head 4, in four rhs-structures, each is all at least provided with three vacuum suction holes 5.
The first described straight line pipeline section 301 and the axial line side projection angle γ of the second straight line pipeline section 301 are between 0-30 degree.
Described portion of the handle 2 is provided with two relative planes 201, and on-plane surface section is provided with the groove 202 increasing frictional force.
Described suction catheter portion 3 is identical with external diameter with the internal diameter of sucking head 4.
Described negative pressure connector portions 1 is provided with anticreep back taper structure 6.
Beneficial effect of the present invention:
The present invention had both had the effect of suction pump, can participate in Pulmonary Vascular separating operation again, especially attracted head and pipe portion to have certain angle β, was conducive to lock out operation and ensured surgical field of view.Pipe portion is designed to non-linear structure and curvature of space structure and is extremely conducive to suction pump in thoracoscope, avoids other operating theater instruments, improves operating theater instruments in thoracoscope and holds quantity.
The present invention, by rational structural design, solves the insurmountable problem of conventional vacuum extractor.It is simple that it has structure, manufacture, advantage easy for operation, is conducive to improving procedure efficiency, and the operating theater instruments reduced in operation process changes number of times.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present invention.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, 2.
Under a kind of thoracoscope, Pulmonary Vascular is separated suction pump, it forms primarily of negative pressure connector portions 1, portion of the handle 2, suction catheter portion 3 and sucking head 4 successively overall being connected, their inside forms through vacuum suction passage, negative pressure is by negative pressure flexible pipe, one connects negative pressure source, the other end is sleeved in the anticreep back taper structure 6 of negative pressure connector portions 1, and negative pressure flexible pipe should adopt internal diameter to be less than the elasticity flexible pipe for medical purpose of negative pressure connector portions external diameter.The internal diameter of suction catheter portion 3 and sucking head 4 and external diameter preferably adopt identical size.The surrounding of described sucking head 4 is provided with multiple vacuum suction hole 5, described suction catheter portion 3 is made up of the first straight line pipeline section 301 of space intersection and the second straight line pipeline section 301, their axis horizontal projection angle α is between 140-170 degree, and the first straightway is connected with portion of the handle 2 coaxial line; Described sucking head 4 is connected with the second direct line 302, and the angle β between both axial lines is between 135-160 degree.As shown in Figure 1, in order to improve the motility of suction pump of the present invention further, preferably make the axial line side projection angle γ of the first straight line pipeline section 301 and the second straight line pipeline section 301 between 0-30 degree during concrete enforcement, as shown in Figure 2.During concrete enforcement, sucking head 4 is preferably designed to four rhs-structures, each is all at least provided with three vacuum suction holes 5.In order to improve the comfortableness of gripping, portion of the handle 2 preferably cuts out two relative planes 201 on a pipe, is provided with the groove 202 increasing frictional force in on-plane surface section simultaneously.
Material used in the present invention should adopt medical stainless steel material to reuse, and medical engineering plastics also can be adopted to manufacture disposable structure.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
