Abstract
The utility model discloses a self-help small incision fixing spreader and relates to a surgical appliance. The spreader is provided with a U-shaped elastic piece; the free ends of the straight edges of the left and right sides of the elastic piece extend forwards respectively to form outward protrusion parts; a screw rod extending in a left-right direction is arranged in the middle of the straight edges of the left and right sides of the elastic piece; the left end of the screw rod is fixedly connected with the straight edge of the left side of the elastic piece, and the right end of the elastic piece penetrates through a through hole in the straight edge of the right side of the elastic piece and extends out rightwards; the middle of the screw rod is screwed with a disc-shaped nut and sleeved with a straight pipe; the straight pipe is positioned between the disc-shaped nut and the straight edge of the right side of the elastic piece, and the inner diameter of the straight pipe is greater than the outer diameter of the screw rod. The spreader is used by one hand of a surgeon and the width of the two sides of the small incision of a patient can be conveniently adjusted.
Description
Technical field
This utility model relates to a kind of surgical operation apparatus.
Background technology
The existing surgery small incision surgery operation of 2-4 centimetre (width of patient's otch both sides) requires an assistant to hook respectively the tissue of patient's otch both sides with two hooklets more, outwards struts, to expose surgical field of view.Progress along with operation, needs assistant constantly to adjust drag hook orientation, and to adapt to operator person's process of performing the operation, this cooperation is wasted time and energy, normally the carrying out of impact operation.Moreover if the cooperation in the reasonable time of process, assistant can not guarantee the best surgical field of view of patient.
Utility model content
This utility model aims to provide the single use of a kind of operative doctor, and can adjust easily the self-service fixedly holding small incision open device with the little otch of immobilized patients both sides width.
The technical solution of the utility model is: self-service fixedly holding small incision open device, is characterized in that: have a shape of a hoof shell fragment, the free end of this shell fragment arranged on left and right sides straight flange extends respectively a male part to front side; The middle part of this shell fragment arranged on left and right sides straight flange is provided with a screw rod extending along left and right directions; The left end of this screw rod is fixedly connected with the straight flange in this shell fragment left side, and the right-hand member of this screw rod freely stretches out to the right through the via hole on the straight flange on this shell fragment right side; The middle part of this screw rod screws togather a plate-like nut and is set with a straight tube; This straight tube between plate-like nut and the straight flange on this shell fragment right side and the internal diameter of this straight tube be greater than the external diameter of screw rod.
During use, operative doctor need only insert the free-ended male part of shell fragment arranged on left and right sides straight flange in the little otch of patient, hold on the other hand shell fragment, another hands rotates plate-like nut, making plate-like nut push away straight tube opens the male part of shell fragment arranged on left and right sides straight flange to the little otch of patient both sides, until reach the narrowest surgical field of view, the plate-like that can stop operating nut.Due to the relation that screws togather of plate-like nut and screw rod, the narrowest surgical field of view has been fixed.While needing to expand surgical field of view in art, operative doctor is held shell fragment again on the other hand, and another hands rotates plate-like nut, makes plate-like nut push away straight tube the male part of shell fragment arranged on left and right sides straight flange is continued to open to the little otch of patient both sides, while reaching the surgical field of view needing, the plate-like that stops operating nut.From but the limit goal of the invention of this utility model " the single use of operative doctor, and can adjust easily and the little otch of immobilized patients both sides width ".
Preferred, implement in structure: the junction of described shell fragment left side straight flange and described screw rod is provided with a setting-up piece, this setting-up piece is fixedly connected with and is integral with the described shell fragment middle part of straight flange, left side and the left end of described screw rod.
Utilize setting-up piece to increase the contact surface of screw rod and shell fragment, increase bonding strength, can increase shell fragment service life effectively.
And then: between described shell fragment right side straight flange and the right-hand member of described straight tube, be provided with a removable insole pieces, the internal diameter of this removable insole pieces is greater than the external diameter of described screw rod.
Utilizing removable insole pieces to expand the contact surface of straight tube and shell fragment, is also to improve the shell fragment effective measures in service life.
Preferred, implement in structure: the straight flange of described shell fragment arranged on left and right sides curves inwardly respectively.
So, the straight flange of shell fragment arranged on left and right sides just can be not crooked, can improve the intensity of outwards propping up little otch both sides tissue.
Preferred, implement in structure: the uniform detent projection of periphery of described plate-like nut.
Utilize detent projection to realize anti-skidding, can improve plate-like nut rotation convenience and can be handling.
The self-service fixedly holding small incision open of this utility model device, adopts above-mentioned structure, while making the single row small incision surgery of operative doctor, saves time, laborsaving and guarantee the narrowest surgical field of view.Can make operative doctor concentrate on operation, effectively improve operation level and efficiency.
