Retractor for neurosurgery department

Abstract

The retractor comprises a box body and an expansion part, the expansion part comprises an expansion assembly, a rectangular shell, two L-shaped rods and two turnover assemblies, the expansion assembly comprises an adjusting handle and a gear, the gear is located on the inner side of the rectangular shell, the lower end of the adjusting handle penetrates through the top wall of the rectangular shell to be in key connection with the gear, and the adjusting handle is in threaded connection with the rectangular shell; the L-shaped rods are located at the left end and the right end of the rectangular shell respectively and comprise a vertical rod and a transverse rod which are fixedly connected, teeth in meshed connection with the gear are arranged at the end, away from the vertical rod, of the transverse rod, the overturning assembly comprises a rotating block, a concave block and a main retracting part, the rotating block and the concave block are movably connected, and the main retracting part comprises a main retracting shell, a locking assembly and a main retracting block which are fixedly connected. The locking assembly is movably connected with the main retraction shell, the main retraction block is fixedly connected to the outer side of the bottom wall of the main retraction shell, and the concave block is fixedly connected to the middle position of the outer side of the top wall of the main retraction shell; and the multiple auxiliary retraction parts are movably connected to the left end and the right end of the main retraction part correspondingly.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a neurosurgery retractor. Background technique [0002] Neurosurgery is the application of unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, as well as its related subsidiary organs, such as the skull and scalp, on the basis of surgery as the main treatment method. , cerebrovascular meninges and other structural damage, inflammation, tumors, deformities and certain genetic metabolic disorders or dysfunctional diseases. [0003] However, the existing neurosurgery often needs to use retractors during the operation, and the general retractors need to be fixed by external clamping or traction, and most of the retractors are not able to adjust according to the patient's wound. To adjust the suitable size by yourself, several different retractors are often used, which is cumbersome to use and ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing neurosurgery often needs to use retractors during the operation, and the general retractors need to be fixed by external clamping or traction, and most of the retractors are not able to adjust according to the patient's wound. The size can be adjusted by yourself, and several different retractors are often used. This kind of use process is more troublesome, and it cannot improve the speed and sensitivity of the doctor's operation.
