The functional assembly comprises a first shell, a glans penis sleeve, a nail plate, a pull rod, a nail box, a scalpel and an ejector. The actuating unit assembly comprises a second shell, a gun core, a screw, a nut push rod and a first elastic part. The nail plate is arranged at the edge of the glans penis sleeve. The outer side of the glans penis sleeve is connected with the pull rod. The nail box is arranged on the inner side of one end of the first shell. The scalpel is located on the inner side of the nail box. The end, away from the glans penis sleeve, of the scalpel is connected with the ejector. A through hole is formed in the middle of the ejector. The pull rod penetrates through the through hole. The end, away from the glans penis sleeve, of the pull rod is connected with the gun core. The screw is arranged outside the gun core. The nut push rod is in threaded connection with the screw. One end of the screw is connected with the second shell. The ejector is pushed by the nut push rod to move. A button is arranged at the end, away from the pull rod, of the gun core. The circumcision device is simple in structure, convenient to use and capable of improving surgery efficiency and stability.

Implementation method for stereotactic electroencephalogram based on Leksell framework

The invention relates to an implementation method for a stereotactic electroencephalogram based on a Leksell framework. The implementation method specifically comprises the steps that firstly, three-dimensional reconstruction is carried out on head MRI data; secondly, an included angle between each electrode and the cross section of the human body is set to be an angle a, and an included angle between each electrode and the median sagittal plane of the human body is set to be an angle beta; thirdly, a deep electrode imbedding plane is formulated according to examines and weighs of a preoperative assessment; fourthly, after a head frame of the Leksell framework is installed in the morning of an operation, and head MRI thin-layer chromatographic scanning is carried out; fifthly, preoperative MRI and the MRI obtained in morning of the operation are mixed in a Neurotech system; sixthly, three-dimensional coordinate values X, Y and Z of an inlet point and a far point of each electrode are worked out according to developing points of the Leksell framework on the MRI, and the unique space direction angle a value and the angle beta value of each electrode are worked out; finally, the coordinate values, the angle a direction and the angle beta direction are adjusted on the head frame of the Leksell framework, and the deep electrodes are accurately and quickly implanted to objective positions through customized operative instruments. According to the implementation method, operation is easy and convenient, and the deep electrodes can be precisely, safely, reliably and quickly implanted to the objective positions.

An intraoperative pathological tissue extractor

InactiveCN104873230BQuick and easy pathological extractionEasy to operateSurgical needlesPump chamberDistal portion
The invention discloses an intraoperative pathological tissue extractor, which comprises a needle tube, a piston assembled in the needle tube, a push-pull rod for controlling the movement of the piston, and a needle head installed at the front end of the needle tube. The front end of the needle point of the needle head is circular The opening is equipped with an extraction cavity that can slide along the needle in the needle barrel of the needle, and the extraction cavity is connected with the piston through a connecting rod. The invention provides a special instrument capable of fast and convenient pathological extraction, which has simple structure, convenient operation and low cost; the circular needle end structure is designed to reduce the impact on the needle as much as possible without affecting the advance of the needle. The influence of other tissues can reduce the probability of bleeding and improve the accuracy of pathological cell collection; the setting of the connecting rod, extraction cavity and other position structures in this scheme enables all the tissues extracted at the end of the needle to enter the extraction cavity without Residing in the needle, the withdrawal chamber can be taken out directly from the back of the syringe, which greatly facilitates the tissue collection process.
