Retractor for spinal surgery

Abstract

The invention discloses a retractor for spinal surgery, and relates to the field of spinal surgery. The retractor for the spinal surgery comprises a bottom plate; a supporting column is fixedly connected to the top of the bottom plate; a telescopic rod is slidably connected to the axis of the supporting column; a fixing head is fixed to the top of the side wall of the telescopic rod; two sets of square rods are fixedly connected to one side, away from a connecting rod, of the fixing head; the two sets of square rods are movably sleeved with square pipes; a fixing pipe is fixedly connected to the bottom of the square pipe; a square groove is formed in the bottom of the fixing pipe; a sliding rod is movably connected into the square groove of the fixing pipe in an inserted mode; a sleeve isfixedly connected to the bottom of the sliding rod; and a retraction cross rod is connected into the pipe cavity of the sleeve in an inserted mode. According to the retractor for the spine surgery inthe invention, the using effect of the retractor for a patient during the surgery is guaranteed; therefore, the surgery is convenient to carry out; the surgery risk is reduced; the retractor is easy and convenient to operate during using; time and labour are saved; and the usage requirements are satisfied.

Description

Technical field [0001] The present invention relates to the field of spinal surgery, in particular a retracting device for spinal surgery. Background technique [0002] In surgical surgery, the steps that are typically revealed using a sand hook or a retracting device, the so-called surgical revealed, the basic process is: cutting the body surface skin, using the hook or the retracted device to pull the human body under the slider , Make the lesions in the body are in an ideal exposed state. [0003] The discussion of spinal surgery in the prior art is generally simple, not convenient for adjustment, so that the removal effect is not good, this has caused a certain impact on surgery, which is not conducive to the operation of surgery, and improves surgery. Moreover, the existing retracting device cannot be installed using the retracted bar of the target according to the removal of the surgery, which results in a long time, and cannot meet the needs of the user, for the prior art....

AI Technical Summary

Problems solved by technology

[0003] The general structure of the retractor for spinal surgery in the prior art is relatively simple, and it is not easy to adjust, so that the retraction effect is not good, which has a certain impact on the operation, which is not conducive to the development of the operation, and increases the risk of the operation. Moreover, the existing retractors cannot be installed with the target number of retractor strips according to the required retraction size of the operation, which leads to a long retraction time and cannot meet the needs of users. In view of the deficiencies in the prior art, We design a retractor for spinal surgery to solve the above problems
