The rear portion of the propulsion tube and the inwall straight-line guidance of the catheter channel are slidably matched, and the propulsion tube passes through periphery
The fin that face ring is set coordinates with the axial block of collet sleeve.
The outer wall of the flap chuck surrounds the annular conical surface that external diameter gradually increases from back to front, the collet sleeve when clamping
Front inner diameter be less than the annular conical surface maximum outside diameter.
The front end running-on of the collet sleeve is the cone mouth structure for being adapted to the annular conical surface.
It is used for and surgical catheters surface damp being fixed with the catheter channel inwall at the body of a gun front end exit
The damping ring of cooperation.
The transmission component includes being driven the driving lever coordinated with the collet sleeve, and the lower end of driving lever is cut with scissors by hinge and the body of a gun
Connect, the upper end lengthwise of driving lever offers U-type groove, correspondence is fixed with the finger in insertion U-type groove on the outer wall of collet sleeve,
Be also associated with kinematic link between the driving lever and trigger, one end of the kinematic link be articulated with the middle part of driving lever, the other end with
Trigger is hinged, and back-moving spring is connected between trigger and the body of a gun.
The hand held surgical conduit of the present invention promotes rifle to be highly convenient for the hand-held behaviour of medical personnel using the form design of pistol
Make, when using medical personnel only need to finger cocking can with by the cooperation of collet sleeve and flap chuck easily, stably
Promotion surgical catheters, the characteristics of it has simple in construction, easy to use, stable operation effectively solve prior art and deposit
The problem of.
Brief description of the drawings
Fig. 1 is the structural representation that hand held surgical conduit of the present invention promotes rifle；
Fig. 2 is flap chuck and the half sectional view of collet sleeve in Fig. 1.
Embodiment
The hand held surgical conduit propulsion rifle of the present invention employs the design of conventional pistol pattern, as shown in Figure 1 and Figure 2,
It includes being provided with the catheter channel 2 passed through for surgical catheters 14 in the body of a gun 1, lever 11 and the trigger 10 installed, the body of a gun 1 and pacified
The propulsive mechanism advanced equipped with driving surgical catheters 14, the propulsive mechanism includes the propulsion tube for being used to be set in outside surgical catheters 14
3, flap chuck 4 is integrally formed with the front end of propulsion tube 3 and collet sleeve 5 is set with outside propulsion tube 3, the front end of collet sleeve 5 with
Flap chuck 4, which coordinates, can be clamped and drive surgical catheters 14 to push ahead, and the rear end of the collet sleeve 5 is axially kept off with propulsion tube 3
Only coordinate, to drive propulsion tube 3 to be moved rearwards by reset, the collet sleeve 5 passes through the transmission component that is installed in the body of a gun 1 and trigger 10
Moved back and forth before and after drive connection driving propulsion tube 3.In the present embodiment, flap chuck 4 is elastic construction, and it is provided with two or more
Lobe, the outer wall of the flap chuck 4 surrounds the annular conical surface 40 that external diameter gradually increases from back to front, and collet sleeve 5 when clamping
Front inner diameter be less than the annular conical surface maximum outside diameter, when collet sleeve 5 is moved forward, collet sleeve 5 passes through its inner hole wall and valve
The cooperation of the outer ring conical surface of shape chuck 4, drives each lobe of flap chuck 4 synchronous to central reduction, so as to clamp what is passed through in it
Surgical catheters 14, drive flap chuck 4 to move forward simultaneously after collet sleeve 5 is moved to the preceding dead-centre position of flap chuck 4, from
And drive surgical catheters 14 are synchronous to push ahead by flap chuck 4；When collet sleeve 5 is moved rearwards by, each folder of flap chuck 4
Valve is departed from the constraint of collet sleeve 5 and opened automatically using elasticity, surgical catheters 14 is unclamped, when collet sleeve 5 is moved backward to and is pushed away
During the rear dead-centre position that the block of inlet pipe 3 coordinates, drive propulsion tube 3 is synchronous to be moved rearwards by resetting, and surgical catheters 14 are managed using it
The frictional force between catheter channel inwall in wall and the body of a gun 1 and stop movement, repeat cocking 10, you can utilize collet sleeve
5 promote surgical catheters 14 with the cooperation of propulsion tube 3, flap chuck 4, and a little is pushed ahead.In the present embodiment, it is being promoted
Fin 30 is equipped with the outer peripheral face of pipe 3, is coordinated by the axial block in the rear end of the fin 30 and collet sleeve 5.
In concrete application, the transmission component being connected between trigger 10 and collet sleeve 5 includes being driven what is coordinated with collet sleeve 5
