Problems solved by technology

In the clinical operation process, due to the different diameters of the cervix of different people, the diameter of the cross-section of the existing uterine cup is fixed and cannot be adjusted flexibly. When the diameter of the cervix is ​​large, it will be tight and difficult to fit; and When the diameter of the cervix is ​​small, the cervix cannot be fitted accurately, resulting in easy damage to adjacent parauterine tissues when cutting the fornix

Embodiment Construction

[0015] Combine below figure 1 , figure 2 Introduce the present invention in detail:

[0016] A lifting device with an adjustable cup body, comprising a lifting cup 1, a guide rod 2 and a hollow joystick 3 connected with the lifting cup, the lifting cup body is composed of at least two blades 11 distributed along the same circumference, Generally, 3 pieces, 4 pieces, 6 pieces, etc. can be used. The blades can be straight plates or arc plates. The arcs are located on the same circumference; this can ensure that when the blades are opened or closed, the rotation distance to each direction is equal; at the same time, each of the blades has a wide upper end and a narrower lower end to avoid mutual interference between the lower ends during the rotation process; each of the blades Curls 12 are outwardly formed on the upper end to reduce damage to the cervix when the blades are in contact with the cervix.

[0017] In the present invention, the middle part of each blade in the axi...

Abstract

The invention relates to a medical instrument, in particular to a cup-adjustable uterine manipulator. The cup-adjustable uterine manipulator comprises a uterine manipulator cup, a guide rod and a hollow operating rod connected with the uterine manipulator cup, wherein the uterine manipulator cup consists of at least two blades distributed along the same circumference; the middle of each blade in the axial direction is hinged to a support frame; the lower end of each blade is hinged to a hollow adjusting rod; the hollow adjusting rod moves up and down to drive each blade to rotate around the support frame and is arranged in the inner chamber of the operating rod; and the guide rod penetrates the inner chamber of the adjusting rod to be connected with the support frame and can move up and down along the inner chamber of the adjusting rod. According to the cup-adjustable uterine manipulator, the adjusting rod moves up and down to drive the lower ends of the blades to move and to enable the blades to rotate around the fixed axis, so that the blades are stretched or gathered to realize adjustment of the cup size, and the purpose that the uterine manipulator is suitable for different cervical diameters is achieved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a uterine lifting device with an adjustable cup body. Background technique [0002] At present, the lifting cup is widely used in laparoscopic hysterectomy. The middle part of the lifting cup is pierced with a guide rod. The guiding rod extends into the uterine cavity. The lifting cup contains the cervix and is used to push the uterus to the abdominal cavity to achieve full exposure and purpose of controlling direction. Especially in total laparoscopic hysterectomy, it is necessary to cut the fornix along the contour of the cup to remove the uterus. In the clinical operation process, because the diameter of the cervix varies from person to person, the diameter of the cross-section of the existing uterine cup is fixed and cannot be adjusted flexibly. When the diameter of the cervix is ​​large, it will be tight and difficult to fit; and When the diameter of the cervix is ​​small,...
