Abstract
Disclosed is a novel surgery retractor. The novel surgery retractor is characterized in that both a rotary disc and a support frame are circular, the support frame sleeves the outer periphery of the rotary disc, round holes are formed in the side wall of the rotary disc, balls are connected in the round holes, a ball groove is formed in the inner wall inside the support frame to serve as a ball slide, the balls rotate in the ball groove, and the rotary disc is provided with a spiral slide.
Description
Technical field
this utility model relates to a kind of Novel retractor.
Background technology
existing surgery tractor is straight hook shape, can only be by manually pulling in the time of the distance that need to regulate drag hook to pull open, cannot realize collaborative exerting oneself at all, and more cannot realize the adjusting of wound width.
Summary of the invention
the purpose of this utility model is to provide and a kind ofly realizes collaborative Novel retractor firmly by rotation.
above-mentioned object realizes by following technical scheme:
a kind of Novel retractor, its composition comprises: rotation disc, and described rotation disc is circular, bracing frame is annular, described bracing frame is enclosed within rotation disc excircle, described rotation disc sidewall has circular hole, connects ball in described circular hole, and described bracing frame inside side walls has ball groove as ball slideway, ball rolls in ball groove, described rotation disc has slideway, and described slideway is spiral type
described Novel retractor, the inner side linking springs groove of described bracing frame, linking springs in described spring groove, described spring connects surgery tractor by spring stop piece.
described Novel retractor, the tail end of described surgery tractor has spring stop piece, and the front end of described surgery tractor has hook, and the lower end of described surgery tractor connects carriage, and described carriage connects described rotation disc.
described Novel retractor, described carriage comprises slide bar, and described slide bar has upper stop piece, and described slide bar vertically aligns with described slideway, and described slide bar gos deep into described slideway, and the lower end of described slide bar connects lower stop piece.
beneficial effect:
1. the tail end linking springs of surgery tractor of the present utility model, makes surgery tractor have stable Telescopic and tightr with being connected of slideway.
this utility model makes surgery tractor flexible by the rotation of rotation disc, and the distance of telescopic variation is rounder and more smooth accurately, is convenient to regulate and realizes uniform stressed wound pulled apart, and conveniently regulate the width of wound, is conducive to the carrying out of operation.
the lower end of surgery tractor of the present utility model connects carriage, makes surgery tractor and carriage jointly flexible, does not affect the work space of surgery tractor.
brief description of the drawings:
accompanying drawing 1 is the top view of this product.
accompanying drawing 2 is drag hook place detailed maps of accompanying drawing 1.
detailed description of the invention:
embodiment 1:
1. a Novel retractor, its composition comprises: rotation disc 1, it is characterized in that: described rotation disc is for circular, bracing frame 4 is annular, described bracing frame 4 is enclosed within rotation disc excircle, described rotation disc sidewall has circular hole, in described circular hole, connect ball 3, described bracing frame 4 inside side walls have ball groove as ball slideway, ball rolls in ball groove, and described rotation disc has slideway 2, and described slideway is spiral type, this structure is rotated rotation disc in bracing frame, and surgery tractor is stretched by the radius change of spiral ramp.
embodiment 2:
novel retractor described in embodiment 1, is characterized in that: the inner side of described bracing frame has spring groove 5, linking springs 6 in described spring groove, and described spring connects surgery tractor 7 by spring stop piece.This structure makes surgery tractor have Telescopic and tightr with being connected of slideway.
embodiment 3:
novel retractor described in embodiment 2, it is characterized in that: the tail end of described surgery tractor has spring stop piece 8, the front end of described surgery tractor has hook 9, and the lower end of described surgery tractor connects carriage 10, and described carriage connects described rotation disc.The horizontal slip in spring groove of the spring stop piece of this structure, make surgery tractor can deflection can only horizontal extension, flexible more stable.
embodiment 4:
novel retractor described in embodiment 3, it is characterized in that: described carriage comprises slide bar 11, described slide bar has upper stop piece 12, and described slide bar vertically aligns with described slideway, described slide bar gos deep into described slideway, and the lower end of described slide bar connects lower stop piece 13.The slide bar of this structure is in slideway, and slideway, by the rotation varied radius of rotation disc, makes elastic force more stable because the tail end linking springs catch 8 of surgery tractor blocks spring, so slide bar 11 and surgery tractor can be elastic with the variation of slideway radius.When use, only need rotate rotation disc 1, drag hook all can be simultaneously along with the rotation of rotation disc 1 is along with spiral ramp is elastic, can the wound of operation be pulled open, and according to requirements of operation control width simultaneously, after operation, rotate rotation disc 1 drag hook is moved inward along slideway, take off from wound.
Claims (4)
