Description
Technical field
This utility model relates to medical technical field of medical instruments.
Background technology
Clinical surgery operation particularly must conventional cleaning lymph node in cancer surgery, in practical operation, usually use certain apparatus clamp lymph node to be excised again, but lymph node has self softer feature, itself fundamental form does not become a metastable profile, especially its change of shape extremely unstable under external force, therefore lymph node extirpation is more difficult.In operation, lymph node is extremely breakable under external force, and is do not allow external force to form extruding to lymph node in the middle of operation, otherwise easily promotes that the cancerous cell of lymph node forms reverse micrometastasis.Lymph node extirpation forceps conventional at present carries out lymph node dissection, but the inner space of its retained part is relatively fixing, therefore be easy to when specification, size are very inaccurate lymph node is extruded or squeezed fragmentation in two hemispherical Shells, once break, tumor cell in lymph node just can be diffused on its hetero-organization, increases some unnecessary troubles to patient.
For the problems referred to above, now need a kind of new device, can solve the problem.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of negative pressure retractor for cleaning lymph node, and this traction apparatus can effectively and clean lymph node fast, can not damage lymph node.
The technical scheme taked for this utility model that solves the problem is: a kind of negative pressure retractor for cleaning lymph node, comprise sucking head, the connecting rod of hollow, handle, described connecting rod is interconnected by bending section and straightway and forms, described sucking head is the hollow structure with attracting concave surface, described attraction concave surface is provided with multiple suction hole be communicated with sucking head inside, described sucking head is connected with one end of bending section and is communicated with connecting rod inside, described handle is positioned on the straightway of connecting rod, the connecting rod body of rod of handle with connecting rod junction is provided with the through hole being communicated with connecting rod inside, the end of described link linear section is the opening for connecting negative pressure device.
Preferably, described attraction concave surface is oval, and the long diameter of described attraction concave surface is 10mm, and short diameter is 6.7mm, and the outer surface of sucking head except attracting concave surface is provided with multiple cross projection.
Preferably, described attraction concave surface is circular, and the diameter of described attraction concave surface is 10mm, and the outer surface of sucking head except attraction concave surface is provided with cross one another many oblique lines.
Preferably, the diameter of described suction hole is 1mm to 2mm, and the diameter of described through hole is 5mm.
Preferably, be threaded connection between described sucking head and connecting rod, length 8cm to the 12cm of described bending section, the length of straightway is 23cm to 27cm, and the internal diameter of described connecting rod is 3mm to 5mm, and external diameter is 4mm to 6mm.
The beneficial effect adopting technique scheme to produce is: do not need when this device carries out lymph node dissection to clamp lymph node, sucking head place attracts the suction hole on concave surface to be evenly distributed, so the captivation when it is in subnormal ambient on this attraction concave surface is uniform, so can be very safe and fast lymph node is attracted, lymph node is there will not be to be extruded or the phenomenon of squeezed fragmentation, its structure is simple, easy and simple to handle, time saving and energy saving, alleviate the work difficulty of staff, simultaneously can safe and efficient cleaning lymph node.

Detailed description of the invention
As shown in figures 1 and 3: a kind of negative pressure retractor for cleaning lymph node, comprise sucking head 1, the connecting rod 2 of hollow, handle 3, described connecting rod 2 is interconnected by bending section and straightway and forms, described sucking head 1 is the hollow structure with attracting concave surface 4, described attraction concave surface 4 is provided with multiple suction hole 5 be communicated with sucking head 1 inside, described sucking head 1 is connected with one end of bending section and is communicated with connecting rod 2 inside, described handle 3 is positioned on the straightway of connecting rod 2, connecting rod 2 body of rod of handle 3 with connecting rod 2 junction is provided with the through hole 6 being communicated with connecting rod 2 inside, this through hole 6 penetrates handle 3 simultaneously and communicates with the external world, the end of described connecting rod 2 straightway is the opening 9 for connecting negative pressure device.The diameter of suction hole 5 is 1mm to 2mm, described through hole 6 diameter be 5mm.This through hole 6 position is just in time in patient and holds the rear thumb position of handle 3, therefore patient can pin through hole 6 by thumb easily and makes sucking head 1 be in negative pressure state, when not needing negative pressure, the thumb of pressing through hole 6 is removed, subnormal ambient like this communicates with external environment, then subnormal ambient disappears.Be threaded connection between sucking head 1 and connecting rod 2, the length 8 of described bending section is to 12cm, and the length of straightway is 23cm to 27cm, and connecting rod 2 internal diameter is 3mm to 5mm, and external diameter is 4mm to 6mm.
As shown in Figure 2, attract concave surface 4 be oval, the long diameter of described attraction concave surface 4 is 10mm, and short diameter is 6.7mm, and the outer surface of sucking head 1 except attraction concave surface 4 is provided with multiple cross projection 7, and it is in order to increase skin-friction force.
As shown in Figure 4, attract concave surface 4 be circular, the diameter of described attraction concave surface 4 is 10mm, and the outer surface of sucking head 1 except attraction concave surface 4 is provided with cross one another many oblique lines 8 in order to increase mantle friction.
The concrete use procedure of this device is first be connected with connecting rod 2 by sucking head 1, and connect negative pressure device at the opening 9 of connecting rod 2 straightway, now because there is the through hole 6 communicated with external environment at handle 3 place, therefore sucking head 1 does not exist subnormal ambient.Hand-held handle 3 place by its by mini-incision put to need cleaning lymph node place, the attraction concave surface 4 of sucking head 1 is aimed at the lymph node of required cleaning, the through hole 6 on handle 3 is blocked afterwards with thumb, along with breathing process sucking head 1 inner chamber becomes subnormal ambient, so lymph node is attracted at attraction concave surface 4 place, now again it is excised, therefore the lymph node cut away then is attracted at sucking head 1 place, this device is taken out afterwards from mini-incision, thumb is removed from the through hole 6 on handle 3, then in sucking head 1, negative pressure disappears, lymph node falls down naturally from sucking head 1.
In sum, this device does not need when carrying out lymph node dissection to clamp lymph node, sucking head place attracts the suction hole on concave surface to be evenly distributed, so the captivation when it is in subnormal ambient on this attraction concave surface is uniform, so can be very safe and fast lymph node is attracted, lymph node is there will not be to be extruded or the phenomenon of squeezed fragmentation, its structure is simple, easy and simple to handle, time saving and energy saving, alleviate the work difficulty of staff, simultaneously can safe and efficient cleaning lymph node.
