CN-121987306-A - Saccule puncture outfit with pressure indication and emergency pressure relief functions

Abstract

The invention discloses a saccule puncture outfit with pressure indication and emergency pressure relief functions, and belongs to the field of minimally invasive surgery medical instruments. The puncture outfit comprises a sleeve, a limiting saccule, an indicating saccule and an air bag air guide channel, wherein the limiting saccule is communicated with the indicating saccule through a channel air path, and the indicating saccule is provided with a thin-wall part and an elastic trigger with a tip part. When the pressure of the limiting balloon is normal, the tip part of the elastic trigger is separated from the thin-wall part, and when the pressure is too high, the thin-wall part expands to form a convex balloon to realize visual early warning, and the trigger is pulled to puncture the thin-wall part to release pressure rapidly. The invention can monitor balloon pressure in real time, avoid undervoltage displacement and overvoltage to damage tissues, reduce postoperative complications, fix stably, adapt to multiple positions, operate safely and conveniently, remarkably improve the safety of laparoscopic surgery and the rehabilitation effect of patients, and meet the requirement of medical biocompatibility.

Description

Saccule puncture outfit with pressure indication and emergency pressure relief functions Technical Field The invention relates to the technology of medical instruments, in particular to a puncture outfit system for minimally invasive surgery such as laparoscope and the like. Background In the field of minimally invasive surgery such as laparoscope, the puncture outfit is used as a core medical instrument for establishing a surgery working channel, and the performance of the puncture outfit directly influences the safety and the accuracy of surgery and the postoperative recovery effect of a patient. At present, the puncture outfit fixing modes commonly used in clinic mainly comprise two main types of thread fixing and saccule fixing. The screw thread fixing mode is fixed through mechanical occlusion of a screw thread structure of the outer wall of the sleeve and human tissues, but the screw thread fixing mode has the defects that the fixing stability is greatly influenced by the tissue texture, mechanical damage is easily caused to surrounding tissues, the adjustment difficulty is high and the like, and is limited in application in complex body position operation. The balloon fixing technology has gradually become a mainstream fixing scheme of the minimally invasive surgery puncture outfit by virtue of the advantages of uniform stress, less tissue damage, adaptation to various surgical positions and the like during fixation. The balloon-fixed puncture technique of the prior art is shown in fig. 1-2, in which a positioning balloon 300 disposed outside a cannula 100 enters a human body abdominal cavity 200 along with the cannula 100 in an uninflated state, and then is inflated to be attached to the inner wall of the abdominal cavity 200 to form a support, thereby constructing a stable operation working channel. When the balloon is under pressure, especially when the puncture device is at a special angle (shown in figure 3), the balloon pressure can not be released, and the tissue in the abdominal cavity is continuously extruded, so that the local blood circulation disorder is caused, the tissue edema and ischemic injury are caused, complications such as abdominal pain and abdominal distention are easy to occur after operation, and the recovery period of a patient is prolonged. Disclosure of Invention In order to achieve the aim, the invention provides a balloon puncture outfit with pressure indication and emergency pressure relief functions, which is characterized by comprising a puncture outfit body, a sleeve, a limiting balloon, an indication balloon and an air bag air guide channel; The limiting saccule is in air circuit communication with the indicating saccule through an air bag air guide channel; The indicating balloon is provided with a thin wall part, an elastic trigger is arranged above the thin wall part, and the elastic trigger is provided with a tip part; when the pressure of the limiting balloon is normal, the tip of the elastic trigger keeps a distance from the thin wall part of the indicating balloon; when the pressure of the limiting balloon is too high, the thin wall part of the indicating balloon is expanded to form a convex ball, and the tip part can puncture the thin wall part to realize emergency pressure relief by pulling the elastic trigger.
