Problems solved by technology

However, clinically, because the field of view and operating range of laparoscopy are smaller than those of open surgery, it is difficult to adjust the arterial clip during operation, and it is difficult to open the arterial clip to check the satisfaction of wound suture during the operation.

Embodiment Construction

[0024] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0025] combine figure 1 and figure 2 , a laparoscopic surgery remote control arterial clip provided by the present invention consists of a clip body 1 (the present embodiment adopts a ∝-shaped steel metal clip body), a water bag 2, a threaded thin plastic catheter 3, a screw cap The puncture needle 4 and the water pump 5 with the adjustment knob 6 are composed.

[0026] The clip body 1 is ∝-shaped as a whole and is made of steel sheet with good elasticity. . After clamping the two hind limbs 7, the two forelimbs 8 can be opened, and the front ends of the two forelimbs 8 are curved inwardly in an arc shape. centimeter oval space (average diameter of the renal artery is about 0.6 cm). The forelimb 7 is 0.75 to 1 cm long and 0.3 cm wide, and has an arc-shaped cross section. An empty water sac 2 is respectively fixed on the inn...

Abstract

The invention relates to a remote control bulldog clamp used in a laparoscopic surgery. The remote control bulldog clamp is characterized by comprising a clamp body, wherein one end of the clamp body is two front limbs closed in a normal state, and the other end of the clamp body is a back limb for operating the two front limbs to open; an oval space is defined when the two front limbs are closed, and the short diameter of the oval space is matched with the diameter of the renal artery; the inner surface of each front limb is provided with a water bag, the sum of the diameters of the two water bags filled with liquid is larger than the diameter of the renal artery, and the water bags filled with the liquid can push the two front limbs to open towards the two sides; the water bags are connected with a puncture needle through a thin plastic guiding pipe in the process of puncturing, and are connected with a water pump provided with an adjusting knob in the process of water injection; the diameter of each water bag filled with the liquid is controlled by operating the adjusting knob. Compared with the prior art, the remote control bulldog clamp has the advantages that the artery is blocked and opened while a doctor does not stop cutting, and warm ischemia time of the organs is shortened to the maximum extent.

Description

technical field [0001] The invention relates to a laparoscopic operation remote control arterial clamp, which is mainly used in laparoscopic operation to remotely block arteries outside the body for partial organ resection. Background technique [0002] Laparoscopic surgery is widely used in surgery. The operation is less invasive and recovers quickly. At present, most surgical operations can be performed laparoscopically. However, some operations with strict time constraints, such as partial nephrectomy, may affect the surgical effect of laparoscopic surgery due to the limitation of surgical channel and suturing speed. At present, laparoscopic partial nephrectomy often separates the renal artery first, blocks it with an arterial clip, then performs partial nephrectomy, and releases the arterial clip after the suturing is completed. The international recommended time for this process is 20-30 minutes. If the warm ischemia time is longer, as the warm ischemia time prolongs...
