a palace lifter

Abstract

The invention belongs to the field of medical instruments, and relates to a uterine manipulator. The uterine manipulator comprises: a uterus lifting cup body, wherein the uterus lifting cup body comprises a lifting part, a swinging part, a knuckle bearing and a linkage sleeve, through holes are formed in the centers of the lifting part and the swinging part, the knuckle bearing comprises a bearinginner ring and a bearing outer ring, the bearing outer ring is fixedly arranged in the through hole of the lifting part, and the linkage sleeve is arranged in the bearing inner ring in a sleeved mode; a main shell, wherein a hollow rod is arranged in the main shell, four partition plates are arranged on the outer wall of the hollow rod, and a waist-drum-shaped sliding groove is arranged in the front of the main shell; and a uterus swinging rod which comprises a rod front part, a flexible shaft part and a rod rear part. The uterine manipulator further comprises a rear shell, and a pushing adjusting mechanism, a swing mechanism and a fine adjustment mechanism are arranged on the rear shell. The uterus can be swung through the swing mechanism, the uterus swing rod can be driven to conduct front-back adjusting movement through the pushing adjusting mechanism, and the depth of the uterine cavity of the uterus does not need to be measured in advance; and swing fine adjustment can be conducted on the rod front part through the fine adjustment mechanism, and therefore the swing accuracy is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a uterine lifter. Background technique [0002] With the popularization and application of laparoscopic technology in the field of gynecology, almost all gynecological laparotomy has been replaced by laparoscopic surgery. Moreover, laparoscopic surgery has the advantages of minimally invasiveness, clear vision, fast recovery, and less bleeding that cannot be surpassed by open surgery. The vast majority of gynecological laparoscopic operations are inseparable from an important surgical instrument-uterine lifter. The original design of the uterine lifter is to manipulate the uterus to generate appropriate tension, reveal the surgical space or facilitate access to some special parts of the pelvis. Its application provides an important guarantee for the exposure of the female pelvic surgery field of view. [0003] However, most of the existing uterine lifting devices still use st...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in order to solve the problem of using the uterine lifter in the background technology, it is necessary to measure first and then select the swing rod of the corresponding length to perform the operation. To solve the problem, the present invention provides a uterine lifter, which drives the front part of the swinging uterine rod to swing at a certain angle through the swing mechanism, and the lifting cup body can also swing accordingly, thereby realizing the ability to adjust the swinging angle of the uterus; The adjustment mechanism drives the pendulum rod to move forward slowly, and then the front part of the pendulum rod can completely enter the uterine cavity. This method does not need to measure the depth of the uterine cavity in advance; the linkage sleeve is fine-tuned by the fine-tuning mechanism, The linkage sleeve drives the front part of the pendulum rod to perform fine-tuning of the swing, thus improving the precision of the swing
