Problems solved by technology

However, there is also the need to temporarily block the blood flow during the operation, and increase the anastomosis, the risk of re-embolization is doubled, time-consuming, and the same as the implantation of the covered stent, the vascular caliber does not match, the inelasticity, tortuousness, and long-term Taking anticoagulant drugs, high price and other problems, the overall effect is not good

Embodiment 1

[0025] see figure 1 and figure 2 As shown, a kind of puncture-type blood vessel temporary connector involved in this embodiment includes:

[0026] Tubular water bag 10, the tubular water bag 10 is provided with filling and discharging water port 11;

[0027] The puncture guide wire 20 is arranged on the wall of the tubular water bladder 10 , and the puncture guide wire 10 extends along the length direction of the tubular water bladder 20 .

[0028] In this embodiment, firstly, the tubular water bag 10 is in an unfilled state, and it is shriveled and tightly attached to the puncture guide wire 20 (such as figure 2 As shown), it is inserted into one of the two blood vessels to be sutured, and the puncture guide wire 20 is positioned between the two blood vessels to be sutured. Bulge and reach a state of expansion (such as figure 1 As shown), the pre-positioned connection of the two separated blood vessels is realized, and the blood circulation can still be ensured in the h...

Embodiment 2

[0030] see figure 1 and figure 2 As shown, a puncture-type temporary blood vessel connector involved in this embodiment is further configured on the basis of Embodiment 1. The tubular water bag 10 is provided with a nozzle 30 communicating with its interior, The water filling and discharging port 11 is arranged on the guide nozzle 30 .

[0031] In this embodiment, by setting the guide nozzle 30 on the tubular water bag 10 and setting the water filling and discharging port 11 on the guide nozzle 30, it is convenient to perform the water filling and discharging operation on the tubular water bag 10 .

Embodiment 3

[0033] see figure 1 and figure 2 As shown, the puncture-type temporary blood vessel connector involved in this embodiment is further configured on the basis of Embodiment 2, and the guide nozzle 30 is provided near the end of the tubular water bag 10 .

[0034] In this embodiment, by setting the guide nozzle 30 near the end of the tubular water bag 10, the insertion site is far away from the suturing position, which is convenient for the surgeon to perform the suturing operation.

Abstract

The invention discloses a puncture type temporary blood vessel communicating vessel. The puncture type temporary blood vessel communicating vessel comprises a tubular water bag and a puncture guide wire, wherein a water charging and discharging opening is formed in the tubular water bag; the puncture guide wire is arranged on the wall of the tubular water bag and extends in the length direction of the tubular water bag; a guide nozzle communicated with the inside of the tubular water bag is arranged on the tubular water bag, and the water charging and discharging opening is formed in the guide nozzle; the guide nozzle is arranged in the position, close to the end, of the tubular water bag; the tubular water bag is made of an elastic flexible material; and the outer wall of the tubular water bag is yellow. The temporary blood vessel communicating vessel has the characteristics of ingenious structure and safety in use, smooth blood supply of blood vessels can still be guaranteed during surgical suture, the overall function is complete, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a puncture type blood vessel temporary connector. Background technique [0002] Injury to large blood vessels in the extremities will lead to limb ischemia and amputation. Timely vascular repair surgery can avoid limb necrosis. It often takes more than 2 hours from injury, admission to the hospital, entering the operating room to recanalization of blood vessels during the operation, and the recovery of nerve and muscle tissue functions after ischemia for more than 1.5 hours is often poor. Since the time from injury to hospital admission is uncontrollable, if the recanalization time during surgery can be shortened, thereby shortening the ischemia time of the distal limb, the disability rate and disability level of the affected limb will be reduced to a certain extent. [0003] In the current vascular repair operation, the routine operation is to block ...
