Abstract
The utility model discloses a psoas retractor which is used for surgery visual field exposure in spinal column and myeleterosis surgeries for lubar intervertebral disc protrusion and belongs the field of medical instruments. The psoas retractor comprises two tractive blades used for stretching and stopping psoas and other soft tissues, wherein the two blades are connected through a joint; an adjusting knob used for controlling the opening and closing degree of the blades are arranged at the root parts of the two blades, and knob threads are ladder-shaped, so as to increase the tractive force and reduce the abrasion. By adopting the utility model, the peeling ranges of the psoas and the skin incision are minimized, the surgery injure is small, the surgery effect is good, the postoperation ache of a patient is alleviated, the myodynamia recover is good, the disease recurrence rate is low, so that the physical and psychological health of the patient is greatly promoted.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind ofly is used for the psoas muscle retractor that spinal column such as prolapse of lumbar intervertebral disc, myeleterosis operation appear the art open country.
Background technology
Prolapse of lumbar intervertebral disc is a kind of commonly encountered diseases, high morbidity, and sickness rate can be up to 12.2%, and part patient needs operative treatment.Classical operation is a diskectomy, exposes the wild posterior fossa retractor that adopts of art in the present operation, and about 7,8 centimetres of operative incision can reach tens centimetres in case of necessity, peels off the bilateral psoas major behind the incision skin, inserts posterior fossa retractor and retracts to both sides.Because of about 5 centimetres of the metal claw of retractor, the about 5-6 of the psoas muscle degree of depth centimetre, the wild difficult exposure of art.Exist operative incision long, expose the wild difficulty of art, postoperative patient pain obviously, psychological burden heavily waits shortcoming.How to shorten operative incision, it is satisfied to reach the wild exposure of art simultaneously as far as possible, and the misery that as far as possible alleviates patient is the target that the surgeon pursues always.
Summary of the invention
The purpose of this utility model is in order to overcome the above-mentioned shortcoming of present classical operation, can use this operating theater instruments reduce operative incision, alleviate under the prerequisite of surgical injury as far as possible as far as possible, satisfied surgical field of view is provided, reach best operative effect, promote patient's physical and mental health to greatest extent.
For achieving the above object, the technical solution of the utility model is: the psoas muscle retractor, comprise two tractive blades that play tractive, stop soft tissues such as psoas muscle, two blades are linked to each other by the joint, the root of two blades has the adjusting knob of control blade folding degree, the knob screw thread is trapezoidal, to increase the tractive dynamics and to alleviate wearing and tearing.
Using method of the present utility model is: after cutting skin in the art, electric knife cuts the attachment point of psoas muscle on ridge is prominent, adopts the limit tractive, struts, and the method for retractor is goed deep on the limit gradually, up to vertebral plate.Conventional at present surgical field of view process for exposing, about 7,8 centimetres of skin incision, because of the great power of psoas muscle, peeling off the psoas muscle scope needs extensively, otherwise the surgical field of view that is difficult for reaching satisfied appears.Adopt this retractor, about 3 centimetres of skin incision, the psoas muscle dissection scope is little, cooperates the microscopically operation technique, can reach satisfied surgical field of view and appear good operation effect.
The beneficial effects of the utility model are: can reach minimum in the art on skin incision, psoas muscle dissection scope, surgical injury is little, good operation effect, and postoperative patient pain is light, Myodynamia recovery good, the palindromia rate is low, promotes patient's physical and mental health to greatest extent.
