The rear portion of the propulsion tube and the inner wall straight-line guidance of the catheter channel are slidably matched, which passes through periphery
The fin and collet sleeve axial direction block that face ring is set cooperate.
The outer wall of the petaloid collet surrounds the annular conical surface that outer diameter is gradually increased 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.
Be fixed on the catheter channel inner wall at the body of a gun front end exit for surgical catheters surface damp
The damping ring of cooperation.
The transmission component includes the driving lever with collet sleeve transmission cooperation, and the lower end of driving lever is cut with scissors by hinged shaft and the body of a gun
It connecing, the upper end lengthwise of driving lever offers U-type groove, the corresponding finger being fixed in insertion U-type groove on the outer wall of collet sleeve,
Be also connected 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 reset spring is connected between trigger and the body of a gun.
Hand held surgical conduit of the invention promotes rifle to be highly convenient for the hand-held behaviour of medical staff using the form design of pistol
Make, when use medical staff only need to finger cocking can by the cooperation of collet sleeve and petaloid collet easily, stablize
Promotion surgical catheters, have the characteristics that structure is simple, easy to use, stable operation, the effective solution prior art is deposited
The problem of.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that hand held surgical conduit of the present invention promotes rifle；
Fig. 2 is the half sectional view of petaloid collet and collet sleeve in Fig. 1.
Specific embodiment
Hand held surgical conduit of the invention promotes rifle using the design of conventional pistol pattern, as shown in Figure 1 and Figure 2,
It includes the trigger 10 of the body of a gun 1, lever 11 and installation, and the catheter channel 2 passed through for surgical catheters 14 is equipped in the body of a gun 1 and is pacified
Equipped with the propulsive mechanism that driving surgical catheters 14 are advanced, which includes the propulsion tube for being set in outside surgical catheters 14
3, be integrally formed with petaloid collet 4 in the front end of propulsion tube 3 and be set with collet sleeve 5 outside propulsion tube 3, the front end of collet sleeve 5 with
The cooperation of petaloid collet 4 can clamp and surgical catheters 14 is driven to push ahead, the rear end of the collet sleeve 5 and the axial gear of propulsion tube 3
Only cooperate, to drive propulsion tube 3 to move backward reset, which passes through the transmission component that is installed in the body of a gun 1 and trigger 10
It is moved back and forth before and after transmission connection driving propulsion tube 3.In the present embodiment, petaloid collet 4 is elastic construction, is equipped with two or more
Lobe, the outer wall of the petaloid collet 4 surrounds the annular conical surface 40 that outer diameter is gradually increased 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 move forward when, collet sleeve 5 pass through its inner hole wall and valve
It is synchronous to central reduction to drive each lobe of petaloid collet 4 cooperation of 4 outer ring conical surface of shape collet, passes through in it to clamp
Surgical catheters 14 drive petaloid collet 4 while being moved forward after collet sleeve 5 is moved to the preceding dead-centre position of petaloid collet 4, from
And it drives surgical catheters 14 to synchronize by petaloid collet 4 and pushes ahead；When collet sleeve 5 moves backward, each folder of petaloid collet 4
Valve is detached from the constraint of collet sleeve 5 and utilizes the automatic opening of elasticity, surgical catheters 14 is unclamped, when collet sleeve 5 moves backward to and pushes away
When the rear dead-centre position of 3 block of inlet pipe cooperation, drives propulsion tube 3 to synchronize and move backward reset, and surgical catheters 14 utilize its pipe
The frictional force between catheter channel inner wall in wall and the body of a gun 1 and stop moving, repeat cocking 10, i.e., using collet sleeve
5 with the cooperation of propulsion tube 3, petaloid collet 4 push surgical catheters 14, and a little is pushed ahead.In the present embodiment, promoting
It is equipped with fin 30 on the outer peripheral surface of pipe 3, is cooperated by the fin 30 and the rear end axial direction block of collet sleeve 5.
In concrete application, the transmission component being connected between trigger 10 and collet sleeve 5 includes and the transmission cooperation of collet sleeve 5
The lower end of driving lever 7, the driving lever 7 is hinged by hinged shaft 8 and the body of a gun 1, and the upper end lengthwise of driving lever 7 offers U-type groove, and in collet
The corresponding finger 6 being fixed in insertion U-type groove, transmission is also connected between driving lever 7 and trigger 10 and is connected on the side outer wall of set 5
Bar 9, middle part, the other end and 10 upper back of trigger that one end of the kinematic link 9 is articulated with driving lever 7 are hinged, to realize trigger 10
And collet sleeve 5 automatically resets, and is connected with reset spring 12 between trigger 10 and the body of a gun 1.
Further, it is pushed ahead to ensure that surgical catheters are stable, it is logical in the conduit at 1 front end exit of the body of a gun
Embedded with the damping ring 13 for cooperating with 14 surface damp of surgical catheters in the inner wall in road 2.
