Description

Airway wall bracing wire control mechanism

[technical field]

The utility model is a kind of airway wall bracing wire control mechanism, mainly provides a kind of easy control mechanism, passes through behaviour Make the control sheet of moving handle top to drive the displacement of bracing wire, and can reach the distal end of catheter swing bending for interlocking airway wall Effect is designed particularly in the upper structure of positioning, can stationary remote weave control range, increase the convenience of operation, with into Walk practicability person.

[background technique]

The structure of airway wall generally comprises an elongated conduit, for protruding into inside of human body, the distal colorectal of the conduit Conjunction has photographing module, to shoot the endoceliac image of people and be transmitted to external screen, be able to directly to observe for healthcare givers or It is treated；And in order to obtain the image of inside of human body Difference angles, can be arranged one section in distal end of catheter can be curved Hose construction, and its swing is controlled using two bracing wires, and interlock photographing module steering, to obtain the intracavitary shadow of different multi-angles Picture.

The mechanism that early stage interlocks bracing wire is that the top of airway wall proximal handle is arranged in, and providing user may operate in handle Knob mechanisms on hand control the swing of distal end of catheter to interlock bracing wire, but it needs using both hands while cooperating control, i.e., Handle is held on the other hand, and implements locking using an other hand or screws movement, could position the bending angle of distal end of catheter, phase Work as inconvenience.

Then have the improvement design of the control mechanism using one-handed performance, such as China application No. 200980153972.1 " The patent of invention case of endoscope bending section control mechanism " is interlocked internal to be equipped with a movable button outside hand handle using it Transverse bar drive the movement of bracing wire, and reaching makes the body distal end of airway wall can control swing, only the control mechanism It operates but still not convenient enough, when operator elapses button, and distal end of catheter is made to bend to positioning, it is necessary to press an engaging machine again Structure then needs the movement for separately operating unlock come the button that locks, and when needing to change distal end of catheter angle, for must be high at any time The doctor that degree is absorbed in observation image and performs the operation, must cause quite not convenient puzzlement, and difficulty reaches the demand of known patent institute With the purpose of one-handed performance, therefore still there is necessity of improvement.

[utility model content]

The utility model is a kind of airway wall bracing wire control mechanism, mainly provides a kind of easy control mechanism, passes through shifting The control sheet of dynamic handle top is to drive the displacement of bracing wire, and the distal end of catheter that can interlock airway wall swings incliner, construction Include mainly a runner, be hubbed on the inside of handle, the top of runner is equipped with an accommodation groove, and inside is equipped with a tug of a spring Motion block, and the connecting rod of control sheet of the position above handle is the long slot hole across handle relative position, and fasten with brake block Interlock, the proximal end of two bracing wires be extend be incorporated on the runner of control mechanism, therefore can easily using press control sheet after, with The mode ease of Use of back-and-forth motion reaches the purpose for making distal end of catheter to different lateral bends to interlock bracing wire displacement, and As long as unclamping the finger of pressing, conduit distal end can be located in the angle position, obtain significant progress person.

[specific embodiment]

It please refers to shown in Fig. 1~3, the present embodiment is a kind of airway wall bracing wire control mechanism, is mainly located in the interior of handle (1) Portion, construction includes a runner (2), is hubbed on the inner space of handle (1), forms rotatable structure, runner (2) it is upper Portion is equipped with an accommodation groove (21), and in being set in slot with a spring (31) and a brake block (3), the top of brake block (3) is set as arc Shape, and a slip limiting plate (32) are combined with, handle (1) is set as spherical surface body (11) relative to the upper position of runner (2), and is equipped with One portait slot bore (12), a control sheet (4) are located at the top of handle (1) spherical surface body (11), are equipped with a connecting rod (41) below, And its connecting rod (41) is made to pass through long slot hole (12), and fixation is combined with the centre bore (33) of the stopper piece (3) of lower section, therefore can Brake block (3) turn runner (2) is controlled by the movement of control sheet (4), in addition, the proximal end of two bracing wires (5) of airway wall is Extension is incorporated on the runner (2) of control mechanism.

In use, operator can easily press control sheet (4), makes stopper piece (3) compressed spring (31) downwards, allow Slip limiting plate (32) leaves the inner surface of spherical surface body (11), such as Fig. 4, therefore can easily operate control sheet (4) back-and-forth motion, to interlock Forward and reverse turn of runner (1), and reach control and interlock the relative position for changing two bracing wires (5), and then make distal end of catheter can be with Towards the purpose of different directions bending, as shown in figure five, six, as long as such mode of operation makes implementation personnel can be light using one hand It completes, is very easy to and need not divert one's attention, and when control distal end of catheter bends to a certain special angle position, as long as unclamping pressing Finger, spring (31) just with restoring force ejection stopper piece (3) upwards, so that slip limiting plate (32) is tightly fitted in spherical surface body (11) Inner surface returns to position as shown in Figure 3, that is, may achieve the locating effect such as brake, when runner (3) are fixed in the position, The effect of distal end of catheter is located in the bending angle can be obtained, providing operator need not take a lot of trouble to think to go to tie up with strength more Hold, and can it is wholesouled it is stable observe image acquired by the angle and carry out medical act, reach the utility model it Progress practical value person.

In summary, the control mechanism that the utility model is improved can provide operator and easily be controlled with one hand Airway wall distal end of catheter flexural oscillations processed, and the selected bending angle that can be easily fixed and position, effect More conventional design is shown with more splendid progressive and practicability person.
