Problems solved by technology

[0002] In cardiovascular surgery, it is often necessary to perform intubation operations in the human body. Conventional clinical intubation operations need to be performed entirely by medical staff holding catheters. This hand-held intubation operation requires high operational stability and accuracy for medical staff. , and in the process of hand-held intubation, it is very easy to push the catheter stably due to the blood on the gloves and the catheter, resulting in the failure of the intubation operation

Embodiment Construction

[0013] The hand-held surgical catheter propelling gun of the present invention has adopted the design of conventional pistol style, as figure 1 , figure 2 As shown, it includes a gun body 1, a handle 11 and an installed trigger 10. The gun body 1 is provided with a catheter channel 2 for the surgical catheter 14 to pass through and is installed with a propulsion mechanism that drives the surgical catheter 14 to advance. The propulsion mechanism includes The propulsion tube 3 used to be sleeved outside the surgical catheter 14 is provided with a petal-shaped collet 4 integrally at the front end of the propulsion tube 3 and a collet cover 5 is placed on the propellant tube 3, and the front end of the collet cover 5 is connected with the petal-shaped collet. 4. The cooperation can clamp and drive the surgical catheter 14 to advance forward. The rear end of the collet cover 5 is axially blocked and matched with the propulsion tube 3 to drive the propulsion tube 3 to move backward...

Abstract

The invention discloses a handheld surgical catheter propulsion gun, which comprises a gun body provided with a grab handle and a trigger, wherein a catheter channel through which a surgical catheter passes is arranged in the gun body and a propulsion mechanism for driving the surgical catheter to advance is arranged on the gun body; the propulsion mechanism comprises a propulsion tube sleeving the outside of the surgical catheter; a pedal-type chuck is arranged at the front end of the propulsion tube and a chuck sleeve sleeves the outside of the propulsion tube; the front end of the chuck sleeve is matched with the pedal-type chuck for clamping the surgical catheter and the rear end of the chuck sleeve and the propulsion tube are in axial stop fit; and the chuck sleeve is in transmission connection with the trigger through a transmission assembly arranged in the gun body and drives the propulsion tube to move back and forth in a reciprocating manner. The handheld surgical catheter propulsion gun has the characteristics of being simple in structure, convenient to use and stable in operation, and the problems in the prior art are effectively solved.

Description

technical field [0001] The present invention relates to a kind of medical instrument, mainly relates to the instrument for operation, specifically relates to a kind of hand-held operation catheter propelling gun. Background technique [0002] In cardiovascular surgery, it is often necessary to perform intubation operations in the human body. Conventional clinical intubation operations need to be performed entirely by medical staff holding catheters. This hand-held intubation operation requires high operational stability and accuracy for medical staff. , and it is also very easy to push the catheter stably due to the blood on the gloves and the catheter during the hand-held intubation operation, resulting in the failure of the intubation operation. Contents of the invention [0003] The purpose of the present invention is to provide a hand-held surgical catheter propelling gun with simple structure, convenient use and stable operation. [0004] The technical solution of th...
