Problems solved by technology

The length and width of the currently used surgical retractors are fixed. When surgical operations are performed in deep and shallow tissues, surgical retractors of different depths and widths need to be alternately replaced repeatedly, and the surrounding tissues need to be exposed again when they are pulled apart again. It is inconvenient and prolongs the operation time

Embodiment 1

[0026] figure 1 It is a structural schematic diagram of the surgical retractor in Embodiment 1 of the present invention.

[0027] Such as figure 1 As shown, the surgical retractor 100 with adjustable width and depth conforms to ergonomics, including: a pulling part 1, a driving part 2, a hand-holding part 3, an electric control part 4, and an illuminating part 5, and the pulling part 1 includes a first main board 11 And the second main board 12, the first main board 11 and the second main board 12 all have certain radians, and the radians of the two main boards match, the second main board 12 realizes the relative movement with the first main board 11 under the drive of the driving part 2 One end of the first main board 11 is connected to the hand-held part 3, the hand-held part 3 is approximately cylindrical, and the surface is made of a material with high friction force, which is used to improve the comfort of the assistant when pulling the hook. One side of the hand-held p...

Embodiment 2

[0042] The ergonomic adjustable width and depth surgical retractor provided in Embodiment 1 is electrically regulated, and the surgical retractor can also be manually adjusted.

[0043] The same structures in this embodiment and the first embodiment are given the same symbols, and the same descriptions are omitted.

[0044] Figure 5 It is a structural schematic diagram of the surgical retractor in the second embodiment of the present invention.

[0045] Such as Figure 5 As shown, the surgical retractor 200 with adjustable width and depth conforming to ergonomics includes: a pulling part 7, a moving part 8, a hand-held part 3 and an illuminating part 5, and the pulling part 7 includes a third main board 71 and a fourth main board 72, Both the third main board 71 and the fourth main board 72 have a certain radian, and the radians of the two main boards match. The moving part 8 includes a fastener 81 and a moving clip 82. The upper layer of the moving clip 821 is fixedly conn...

Abstract

The invention provides a width- and depth-adjustable surgical retractor conforming to human mechanics. The surgical retractor comprises a pulling part for hooking tissue, a drive part for driving the first main plate and the second main plate of the pulling part to move relative to each other, a handheld part connected with one end of the first main plate and allowing a user to hold, and a lighting part which is located on the handheld part and used for controlling the electric control part of the drive part and lighting a surgery vision field. The width- and depth-adjustable surgical retractor conforming to human mechanics has the advantages that the width and depth of the surgical retractor can be adjusted freely, the exposing requirements of different surgical sites can be satisfied by one retractor, preparation of multiple retractors of different specifications is not needed, and time for changing surgical retractors is saved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a surgical retractor conforming to human body mechanics and adjustable in width and depth. Background technique [0002] The degree of exposure of the surgical field is one of the important factors determining the success of the operation. To expose the surgical field during the operation, it is necessary to use surgical retractors to pull away the tissues around the surgical field to avoid side damage. Different tissue parts require different specifications of surgical retractors. For example, shallower tissue parts in the abdominal cavity need shallower and wider surgical retractors; deeper tissue parts require deeper and narrower surgical retractors. hook. The length and width of the currently used surgical retractors are fixed. When surgical operations are performed in deep and shallow tissues, surgical retractors of different depths and widths need to be alterna...
