Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to a kind of blood vessel clip.
Background technique
In the course of surgery, it when discovery lesion needs operation excision, in order to guarantee the steady implementation of surgical procedure, needs temporarily
When close corresponding blood vessel, related researcher also develops the blood vessel clip for closing blood vessel.
Such as: CN105054989B discloses a kind of disposable blood pipe clamp, including the first clamp arm and the second clamp arm, the first clamp arm
Inner end and the second clamp arm inner end elastic connection, the outer end of the first clamp arm is equipped with grab, and the outer end of the second clamp arm is equipped with and card
The deck of hook cooperation, which has clamping blood vessel rear stability good, is hardly damaged in use process, however two clamp arm
Shared space is larger.CN201519174U disclose it is a kind of press from both sides the blood vessel clip that closes for human vas, including clamp, latch,
Grab, deck, blood vessel mounting board and clamping hook seat, each section are molded into a whole, although the blood vessel clip can facilitate the operation of doctor to grasp
Make, however, on the one hand since, by very big bending stress, junction is easily damaged, is broken, so as to cause blood on the outside of arcuate socket
Pipe clamp falls off, and on the other hand since arcuate socket two sides position is very thin, the quality at arcuate socket is difficult to stablize control in process of production
System, is easy to produce defective products.
The deficiency as existing for the above product and the inconvenience used, in actual operation, surgeon is for closing blood vessel
Tool and method is as follows: (1) temporarily clamping blood vessel with haemostatic clamp, blood is avoided to flow out；(2) by suture knot tying techniques to blood vessel
It is ligatured；(3) it is knotted catheter and haemostatic clamp locks blood vessel in conjunction with by way of.
For first method, when clamping blood vessel by haemostatic clamp, the operation short for the time is feasible, but very for the time
Long operation, hand-held haemostatic clamp is obviously improper for a long time by special messenger, and hand-held haemostatic clamp not only influences the convenience of surgical procedure, In
Also easily occurs accident in use process；For second method, just in case there is loose ends or off-line in surgical procedure, can cause interior
Bleeding, and wound healing is slower；For the third method, by insufficient, the Yi Songkai with catheter institute knot tightness, because
This needs further to be clamped institute's knot with haemostatic clamp, but haemostatic clamp the space occupied is big, not only influences surgical procedure just
Benefit is also easy to appear accident in use.
To sum up, it is necessary to a kind of small in size, convenient to use and disassembly blood vessel clip is designed, to solve to close blood vessel in operation
When there are the problem of.
