Embodiment 1

[0023] Reference manual attached Figure 1-2 , a retractor for laparoscopic liver surgery, used to cooperate with laparoscope, can be used for pulling and exposing the liver during laparoscopic liver surgery, the pulling effect is accurate, it is not easy to slip, and it can better improve the performance of laparoscopic liver surgery. The exposure of the operative field reduces the difficulty of the operation, reduces the number of surgical instruments inserted into the laparoscopic poke hole during the operation, and provides certain convenience for the successful completion of the operation. The retractor for laparoscopic liver surgery includes an outer tube, a push rod, a branch rod, and a pulling member; wherein the push rod, the branch rod, and the pulling member jointly form an accommodating space for sheathing and pulling the liver .

[0024] The outer tube, the outer tube is tubular, preferably circular, the diameter of the outer tube is 5 mm, and the two ends of the...

Abstract

The embodiment of the invention provides a tractor for liver operation under a laparoscope, and belongs to the technical field of tractors under laparoscopes. The tractor for liver operation under thelaparoscope comprises an outer pipe, a push rod and a traction piece, wherein the two ends of the outer pipe are through, the push rod is arranged inside the outer pipe, the push rod can stretch andretract inside the outer pipe, the traction piece is arranged on the push rod, the push rod and the traction piece form a containing space, the containing space is a closed ring shape, the containingspace can act on the liver, and the liver is pulled by the push rod. The technical effects that the operation space requirement is small, and liver traction is convenient are achieved.

Description

technical field [0001] The invention relates to the technical field of laparoscopic retractors, in particular to a retractor for laparoscopic liver surgery. Background technique [0002] Laparoscopic liver surgery is widely carried out in hospitals across the country. When the liver is transected, the liver needs to be stretched to expose it. However, there is currently a lack of an exposing forceps specially used for laparoscopic liver surgery, and splitting forceps are often used to expose the liver, which has the problems of poor liver exposure and easy damage to the liver causing bleeding. [0003] Therefore, the technical problem of the prior art is that the operation of the separating forceps requires a large space, and the liver is easily damaged when the separating forceps pull the liver. Contents of the invention [0004] The embodiment of the present application provides a retractor for laparoscopic liver surgery, which solves the technical problem that the spa...
