Description

One kind not using the soft scope handle of anti-broken pipe

Technical field

The utility model relates to one kind not to use the soft scope handle of anti-broken pipe, belong to medical instruments field.

Background technique

Different from traditional surgery, endoscopic technique makes endoscope distal end directly arrive at lesions position, and in endoscope Direct-view is lower to carry out diagnoses and treatment.Have the characteristics that it is easy, efficiently, do not need anesthesia, be small to patient trauma, day crescent is just occurring Different variation gets more and more people's extensive concerning and approves.Wherein soft scope is because it is with good flexibility and convenient behaviour The performance of work is widely used in the fields such as alimentary canal, tracheae, urological department.It is found in clinical diagnosis and treatment, using soft Property scope when being operated, for some medical instruments (biopsy forceps, foreign body forceps etc.) for needing to use handle operation, close to hand The outer tube of shank position is easy to that discounting phenomenon occurs, and largely influences the use of instrument, increases to the operation of user Biggish trouble, working efficiency are low.To solve the above-mentioned problems, it will usually increase by one section not close to the outer tube position at handle The stereoplasm tube (being commonly called as " anti-broken pipe ") of rust steel or plastic material plays anti-folding protective effect.But production cost is increased in this way And production process, it is cumbersome, and be easy to face the risk that stereoplasm tube falls off.

The beneficial effect of utility model

1. traditional soft scope handle, outer tube are the power for a point being subject at port, pressure is very big, in gravity It is easy to give a discount under the active force of effect or the bending in other directions.What the utility model optimization design was connected with outer tube The tube conformation of clamp handle one end is provided with radian using " horn mouth " formula structure now, and contact of the outer tube with port becomes one The contact of bar line, reduces pressure herein, therefore can effectively prevent the discounting phenomenon under gravity.

2. the handle of the utility model, bigger closer to port bore, by the way that the radian of bore passages is arranged, increase outer Activity space of the pipe at clamp handle port plays buffer function further to discounting problem of the outer tube at port.

3. also, the bell-mouth structure of air of the utility model, it can also effectively prevent the steel of outer tube manipulation head movement Cord gives a discount, and is conducive to instrument and preferably operates.

4. the use of anti-broken pipe is eliminated, production cost has not only been saved but also reduces production process, it is easy to operate, without caring for Consider the risk that anti-broken pipe falls off, fundamentally solves outer tube and be easy the phenomenon that giving a discount close at clamp handle port.

Detailed description of the invention

Fig. 1 is the overall structure diagram without using the soft scope handle of anti-broken pipe of the utility model.

Fig. 2 is the partial enlarged view of a-quadrant in Fig. 1.

Specific embodiment

Illustrate specific embodiment of the present utility model below in conjunction with attached drawing.

The technology contents and feature of the utility model will be described in detail by cited embodiment combination attached drawing below.For Facilitate description, "front", "rear" hereinafter is consistent with the direction of the left and right of attached drawing, but this can't be the utility model skill The limitation of art scheme.

In conjunction with Fig. 1 and Fig. 2 illustrate the utility model without using anti-broken pipe scope handle comprising from left to right successively Clamp handle 2, adjustable clamp ring 4 and the bracelet 5 of connection.

Bracelet 5, tail portion is annular in shape.

Outer tube 1, one end are connected with other medical instrument heads with matching, and the other end is inserted into clamp handle 2.Outer tube 1 is the bourdon tube or plastic tube of stainless steel material.It is inserted with movable wirerope 8 in outer tube, manipulates Medical treatment device using wirerope 8 The rotation on tool head.

Clamp handle 2, one end are fixedly connected with bracelet 5, and tie component 3 is inserted in the inside of clamp handle 2, and clamp handle 2 is far from bracelet 5 one End is equipped with the inner cavity of one end insertion for outer tube 1, and clamp handle 2 is being equipped with the sliding slot 6 communicated with inner cavity close to 5 one end of bracelet；Fig. 2 is The partial enlarged view of a-quadrant in Fig. 1.In order to better illustrate bell-mouth structure of air, outer tube and manipulation wirerope are eliminated in Fig. 2. As shown in Fig. 2, the port of inner cavity is bell-mouth structure of air 7, and it is bigger closer to port bore, by the way that the radian of bore passages is arranged, Activity space of the outer tube 1 at 2 port of clamp handle is increased, the contact at 2 port of clamp handle of outer tube 1 is become into connecing for a line Touching, reduces pressure herein, plays effective buffer function for discounting problem of the outer tube at port, fundamentally solve Outer tube of having determined is being easy the phenomenon that giving a discount close at 2 port of clamp handle.The inner cavity of 2 front end of clamp handle uses " horn mouth " formula knot in Fig. 2 Structure, in order to cooperate different size of outer tube, the opening angle α of bell-mouth structure of air 7 can be selected in 0.2 ° -120 °, compared with Good, the opening angle α in present embodiment can be selected in 6 ° -80 °.At bell-mouthed open edge, fallen The processing at angle is allowed to form round and smooth structure.

4 sets of adjustable clamp ring at the sliding slot 6 of clamp handle 2, are slidably connected with sliding slot 6.Have on adjustable clamp ring 4 and holds groove 9.

One end insertion adjustable clamp ring 4 of tie component 3 is located at the part in sliding slot 6；The other end of tie component 3 and inner cavity One end of interior wirerope 8 is fixedly connected.

When in use, adjustable clamp ring 4 is held, bracelet 5 is pulled, to drive tie component 3 and 6 relative motion of sliding slot, is drawn Rod unit 3 drives wirerope 8, manipulates head movement by wirerope 8.

One skilled in the art would recognize that the above specific embodiments are only exemplary, it is to make ability Field technique personnel can better understand the contents of the present invention, and should not be understood as the limit to scope of protection of the utility model System, as long as any equivalent change or modification made by the spirit according to disclosed in the utility model, each fall within the utility model guarantor Protect range.
