Description
Technical field
The present invention relates to technical field of medical instrument, more particularly to the fixing device of 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 section 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 are at home and abroad gradually successfully carried out.But operation requires high, not only to cut off disease
Become, kidney operation section 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 bad, 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 advantageous to accurate tumor resection, especially when suturing aggregation system advantageously, suture is more accurate.But due to the shadow of hot ischemic
Ring, operating time can limit, 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 section structure understands, is advantageous to
Aggregation system and myometrial suture, shorten suture time；Cool fast and reliable, the renal ischaemia time can be obviously prolonged so that big tumour
Possibility is implemented as etc. complicated major operation.The shortcomings that unique is to need the arteria renalis under special blocking device for casting 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 grown, and process is complicated, adds the risk of patient.
