Description

Technical Field

[0001] The present application relates to the technical field of laparoscopic surgical instruments, for example, to a new type of leg stand for laparoscopic surgery. Background Art

[0002] The related art (publication number: CN218451719U) discloses a new type of leg stand for gynecological laparoscopic surgery, including a bed frame. Adjustment boxes are fixedly installed on both sides of the bed frame through clamping bolts, an adjustment slide rod is fixedly installed inside the adjustment box, a movable sleeve seat is sleeved and installed on the outer side of the adjustment slide rod, a support rod extending to the outside of the adjustment box is installed on the top of the movable sleeve seat through an axle bolt, and a leg stand adjustment component is sleeved and installed on the outer side of the support rod. The leg stand adjustment component includes a movable pulley, and a leg support is fixedly installed on one side of the movable pulley through a connecting seat.

[0003] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:

[0004] The new leg stand for gynecological laparoscopic surgery can adjust the spacing between the two side support rods by adjusting the sliding rod and the design of the movable sleeve, thereby changing the distance between the two side leg supports, and finally changing the distance between the patient's legs. However, since the two side support rods slide along the axial direction of the adjustment sliding rod, the various parts of the patient's legs change equidistantly. Spreading the legs of a human body is similar to opening a compass, so it does not conform to the human body structure and is less comfortable.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.
