Description
Technical field
The present invention relates to the fixing device of technical field of medical instrument, more particularly to a kind of 3D trochars and blood vessel clip.
Background technology
Partial nephrectomy is primarily adapted for use in kidney of the diameter of tumor less than 4cm, isolated kidney neoplasms, bilateral kidney neoplasms, kidney
The benign tumours such as hamartoma, and segmental Renal vascular deformity, repeat deformity of kidney with inadequate drainage, limitation injury of kidney with bleeding and
The diseases such as urinary extravasation, the multiple calculus for being confined to kidney up or down pole, operating difficulty is larger, and it is main difficulty is that when performing the operation
Control, the processing of kidney tangent plane and the protection of renal function of bleeding, in recent years, with the improvement and operation of laparoscopic surgical instruments
The progress of technology, laparoscopic partial nephrectomy is at home and abroad gradually successfully carried out.But operation requires high, not only to cut off disease
Become, kidney operation tangent plane is also sutured within the limited time.If do not blocked the kidney base of a fruit in art, though avoid the shadow of the substantially hot ischemic of kidney
Ring, but intraoperative blood loss can increase, and exposure is not good, and difficulty is brought with the relevant structure of identification to removal lesion tissue, or even because going out
Blood and threat to life.If the temporary interruption kidney base of a fruit in art, amount of bleeding will be reduced, and visual area is clean, can accurately recognize pathological tissues,
Be conducive to accurate tumor resection, especially when suturing aggregation system advantageously, suture more accurate.But due to the shadow of hot ischemic
Ring, operating time can have been limited, and renal function in art is inevitable that damaged, especially for solitary kidney or feature
Solitary kidney tumor patient, Renal Function After, which can decline, results even in renal insufficiency.At present, laparoscopic renal artery low temperature
Perfusion operation is carried out under almost without blood state, amount of bleeding is at utmost reduced；Operation tangent plane structure understands, is conducive to
Aggregation system and myometrial suture, shorten suture time；Cooling is fast and reliable, can be obviously prolonged the renal ischaemia time so that big tumour
Possibility is implemented as Deng complicated major operation.Uniquely have the disadvantage the arteria renalis under the special blocking device for casting of needs and laparoscope
Puncture technique, this shortcoming seriously limits popularizing for the operation, and prior art arteria renalis hypothermia perfusion robot is auxiliary
Invasive Technology Department is needed to place aortic sac from femoral artery in the left partial nephrectomy of assisted laparoscopic, sacculus plays the work for blocking blood vessel
With middle pipe is used for pouring perfusion liquid, and operating time is long, and process is complicated, adds the risk of patient.
The content of the invention
The problem of in order to solve to mention in above-mentioned background technology, the present invention provides the fixation of a kind of 3D trochars and blood vessel clip
Device.
To achieve these goals, present invention employs following technical scheme：

To clamp arteries, barrier effect is more preferable, and the inner transverse of base is provided with clamping through-hole, the bottom surface of clamping through-hole and water
Planar tilt, high low on one side on one side, because blood vessel clip is in use, nearer from the axle of clip, subtended angle is smaller, blood vessel clip side clip
Clamping through-hole is penetrated over there from relatively low, is easy to blood vessel clip to be fitted close with ridge, the bottom surface of clamping through-hole is evenly arranged with 3-5
Fixture block and ball are provided with individual neck, each neck, blood vessel clip is facilitated insertion into, and use is more convenient, of the invention consolidates
The danger that interventional procedure is brought can be reduced by determining device, moreover, than the perfusion liquid more low temperature of interventional procedure, because that intervenes leads
Pipe migration very long distance, and being driven in the wrong direction with arterial blood in vivo, so when perfusion liquid reaches kidney, temperature has been raised to
15 to 20 degree, do not reach good cryogenic effect, and fixing device of the invention causes perfusion liquid directly to enter from abdominal cavity, do not had
Convection current, temperature is low, and effect is good.The present invention is simple in construction, easy to operate, can be while fixed sleeving pin and blood vessel clip, are realized
Row hypothermia perfusion is such while interruption artery is carried out in laparoscopic surgery operates, and reduces the filling of laparoscopic renal artery low temperature
The risk of operation is noted, the device is easy to use ingenious, is suitably widely popularized.
