Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.
Example one
Through a plurality of experiments, the inventor finds that one of common pollution sources of the duodenoscope is a forceps lifter. In the prior art, the forceps lifting device is accommodated in an accommodating channel of the end seat, the accommodating channel is provided with a stop block, and the forceps lifting device can only be lifted upwards due to the stop block and cannot be turned backwards, so that the forceps lifting device cannot be thoroughly cleaned and disinfected.
The embodiment of the invention provides the endoscope forceps lifting device convenient to clean and disinfect.
Referring to FIG. 1, there is shown an exemplary view of the overall construction of an endoscope insertion section head end assembly referred to in this example.
As can be seen, the insertion head end assembly is mainly composed of a forceps holder 1, a head end cap 2, an illumination light window 3, an observation light window 5, an end seat 6 and a forceps holder driving assembly 7.
The function and basic arrangement of the components in the plug-in head end assembly are well known to those skilled in the art and will not be described in detail herein.
For this reason, the forceps holder 1 of the present embodiment is preferably disposed in the end seat 6 in a structure convenient for disassembly, so that the forceps holder 1 can be cleaned sufficiently alone during cleaning and disinfection, thereby ensuring the cleaning and disinfection effect.
Referring to fig. 2 and 3, the end seat 6 of the present example is provided with a corresponding seating groove 6-1, and the seating groove 6-1 is configured to be engaged with the corresponding wear block 4 of the caliper raising device and the caliper raising device 1.
The forceps-raising device placement groove 6-1, the forceps-raising device 1, and the fixing structure between the forceps-raising device 1 and the forceps-raising device placement groove 6-1 will be described in detail below.
The clamp lifting device 1 comprises a clamp lifting device body 1-1, wherein a rotating shaft boss 1-2 is arranged at the upper bottom of the clamp lifting device body 1-1, the rotating shaft boss 1-2 is formed by extending the upper bottom of the clamp lifting device body 1-1 outwards, the whole clamp lifting device is of a cuboid structure with a circular arc-shaped top, and a rotating shaft 1-3 is vertically arranged on one side surface of the clamp lifting device body; meanwhile, a corresponding connecting slotted hole 1-4 is formed in the clamp lifting device body 1-1 relative to the rotating shaft 1-3 and is used for being connected with the clamp lifting device driving assembly 7 in a matched mode, so that the clamp lifting device driving assembly 7 can drive the clamp lifting device body 1-1 to rotate around the rotating shaft 1-3.
The clamp lifting device 1 with the structure is detachably arranged in the arranging groove 6-1 through the rotating shaft 1-3 on the clamp lifting device, and can be lifted and lowered (not lifted) in the arranging groove 6-1 around the rotating shaft 1-3 to achieve a required working state.
In order to match with the installation and the disassembly of the pincer lifter 1, the inner side surface of the placing groove 6-1 on the end seat 6 in the embodiment is a smooth plane, the bottom of the inner side groove wall 6-2 (namely, the side close to the illumination light window 3 and the image light window 5) is provided with a rotating shaft connecting structure 6-4, and the rotating shaft connecting structure 6-4 is provided with a corresponding rotating shaft hole so as to match with the rotating shaft 1-3 on the pincer lifter 1; meanwhile, the outer side groove wall 6-3 of the placing groove 6-1 is distributed in a staggered mode with the rotating shaft holes on the inner side groove wall 6-2 and is located in the region of the work rotating direction of the pliers lifting device 1, and the outer side groove wall 6-3 can be matched with a body of the pliers lifting device 1 which is placed in the placing groove 6-1 and is in a work state (a rotating lifting state) and a normal state (a non-lifting state) to guarantee the reliability and the stability of the installation and the rotating work of the pliers lifting device 1 in the placing groove 6-1.
The following illustrates a specific connection structure between the forceps holder 1 and the placing groove 6-1 in this embodiment.
The rotating shaft 1-3 of the forceps lifting device 1 in the embodiment is provided with corresponding limiting grooves 1-31, so that the forceps lifting device is wide at two ends and thin in the middle.
The rotating shaft connecting structure 6-4 on the inner side groove wall 6-2 is correspondingly provided with a rotating shaft hole 6-4a, an inserting groove 6-4b and an inserting sheet 6-4c, the rotating shaft hole 6-4a can be used for inserting the rotating shaft 1-3, and the inserting groove 6-4b can be used for inserting the inserting sheet 6-4 c; the whole inserting piece 6-4c is formed into a roughly rectangular shape, and one side is formed into an arc notch 6-4d which can be matched with the detail of the rotating shaft 1-3 of the forceps lifting device 1. The other side of the insertion sheet 6-4c is provided with a step 6-4e, and the insertion sheet can be taken out conveniently through the step, so that the forceps device 1 can be detached conveniently.
Therefore, the rotating shaft 1-3 of the pliers lifting device 1 is rotatably inserted into the rotating shaft hole 6-4a on the rotating shaft connecting structure 6-4, the limiting groove 1-31 on the rotating shaft 1-3 is just corresponding to the inserting groove 6-4b on the rotating shaft connecting structure 6-4, so that the inserting piece 6-4c is inserted into the inserting groove 6-4b, the arc-shaped notch 6-4d on the inserting piece is just clamped in the limiting groove 1-31 on the rotating shaft 1-3, and effective limiting is formed when the rotating shaft 1-3 moves in the axial direction (namely the length direction), so that the rotating shaft 1-3 cannot be separated from the rotating shaft hole 6-4a, and the reliability and the stability of the pliers lifting device 1 rotating in the installing groove 6-1 are ensured.
Furthermore, in order to match with the plugging and unplugging of the plugging piece 6-4c, the body of the rotating shaft connecting structure 6-4 in the embodiment is preferably a boss structure, that is, the end surface matched with the step 6-4e on the plugging piece 6-4c is a step structure, and the step structure can be matched with the plugging piece 6-4c inserted in the plugging groove 6-4b to form a groove, so that when the plugging piece 6-4c is taken out, a long and thin part can be inserted into the groove to take out the plugging piece, and the operation is very convenient.
In addition, since no stopper is disposed on the inner groove wall 6-2 as in the prior art, in order to further improve the fixing reliability of the clamp lifter 1 and the end seat 6, the stopper 2-1 is correspondingly disposed on the end cap 2 in the present embodiment to stop the clamp lifter 1 (as shown in fig. 4).
If the pincer lifting device body 1-1 rotates around the rotating shaft 1-3 in the opposite direction (i.e. in the opposite working rotation direction), after the pincer lifting device body 1-1 rotates for a certain angle, the pincer lifting device body 1-1 is separated from the outer side groove wall 6-3 of the placement groove 6-1 (as shown in fig. 5), and meanwhile, the rotating shaft holes on the inner side groove wall 6-2 are staggered to be distributed when the outer side groove wall 6-3 is rotated, so that the whole pincer lifting device body 1-1 can horizontally move relative to the placement groove 6-1, the rotating shaft on the pincer lifting device body 1-1 is separated from the rotating shaft hole of the placement groove 6-1, and the whole pincer lifting device 1 is pulled out and detached from the end seat 6 (as shown in fig. 6).
The reverse rotation angle of the forceps raising device 1 can be determined by the structural form of the forceps raising device 1 body and the structural form of the outer side groove wall 6-3, such as 45 degrees.
When the forceps lifting device 1 with the structure is arranged in the end seat 6, the forceps lifting device is rotatably arranged in the arranging groove 6-1 on the end seat 6 through the rotating shaft on the forceps lifting device, and the body 1-1 of the forceps lifting device 1 is matched by the outer groove wall 6-3 and the inner groove wall 6-2 on the arranging groove 6-1 so as to ensure the lifting guide of the forceps lifting device and the insertion and positioning of a fixed guide wire and an instrument; meanwhile, the head end cap 2 sleeved on the end seat 6 limits the steering of the forceps lifting device 1, so that the forceps lifting device can only rotate around the rotating shaft in a forward working direction and cannot rotate in a reverse direction, and the forceps lifting device 1 is guaranteed to work stably and not to loosen or fall off when the head end cap is not detached.
Thus, when the detachable forceps-lifting device structure is used for cleaning and disinfecting, firstly the head end cap 2 is removed, and then the forceps-lifting device 1 is rotated for a certain angle along the direction opposite to the lifting direction of the forceps-lifting device (see fig. 5), so that the body of the forceps-lifting device 1 is separated from the outer side groove wall 6-3 of the placing groove 6-1, and the forceps-lifting device structure can be easily detached from the rotating pivot for cleaning and disinfecting (see fig. 6). The clamp lifting device can be independently and fully cleaned to lift a clamp rotating shaft gap, the clamp lifting device can be fully soaked and cleaned after being detached, the pivot rotating shaft gap and a narrow space between the clamp lifting device and the end seat can be effectively cleaned, and residual infection of dirt and bacteria can be avoided.
Example two
In the conventional duodenoscope, a wire rope channel is extended from an endoscope end seat to an insertion part, and a wire rope can move in the wire rope channel so as to drive a forceps lifter to rotate. The inventor finds that common pollution sources of the duodenoscope come from the steel wire rope and the cavity channel matched with the steel wire rope through a plurality of tests. The surface of the steel wire rope is easy to contact with polluted blood and body fluid and is not easy to clean and disinfect. The steel wire rope cavity is very narrow, the diameter is within 1mm, and a common endoscope cleaning and disinfecting machine does not have a pipeline connected with the steel wire rope cavity and can only carry out cleaning and disinfection in a manual cleaning mode. In the operation process, the forceps lifting device can contact blood and body fluid polluted by a patient, the steel wire rope can also contact the blood and body fluid polluted by the patient, and along with the lifting action of the forceps lifting device, the polluted steel wire rope can move in the steel wire rope cavity channel to pollute the steel wire rope cavity channel, so that the steel wire rope cavity channel is not easy to clean and disinfect thoroughly, and hidden danger is formed.
Based on the embodiment of the invention, the sealed clamp lifting device driving assembly 7 is adopted to drive the clamp lifting device 1, so that the sealing of the steel wire rope cavity on the end seat 6 is ensured, and the cleaning and disinfection after the operation become simple and convenient.
Referring to fig. 7, the driving assembly 7 of the present forceps raising device is mainly formed by the mutual cooperation of a forceps raising device steel wire rope 8 and a forceps raising device steel wire rope protecting sleeve 9.
Referring further to fig. 9 and 10, the wire rope 8 of the forceps holder in this example is a wire rope used in a conventional duodenoscope and is inserted into a wire rope passage of the end seat 6, and one end of the wire rope 8 of the forceps holder is connected to the forceps holder 1, and the other end is connected to a wire rope driving slider 11, a wire rope driving link 13, a wire rope driving crank 14 and a forceps holder lifting lever 12 through a wire rope protecting tube connecting assembly 10 inside the operating part.
On the basis, a steel wire rope protective sleeve 9 of the forceps lifting device is sleeved on a steel wire rope 8 of the forceps lifting device between the end seat 6 and the forceps lifting device 1, one end of the steel wire rope protective sleeve 9 of the forceps lifting device is connected with the forceps lifting device 1 in a sealing manner, and the connecting and matching part of the steel wire rope 8 of the forceps lifting device 1 is covered in a sealing manner; the other end seat 6 of the pliers lifting steel wire rope protective sleeve 9 is in sealing connection, and a sealing cover is arranged at a matching position between a pliers lifting steel wire rope 8 and the end seat 6, so that a sealing connection channel for allowing the pliers lifting steel wire rope to pass is formed between the end seat 6 and the pliers lifting device 1, the sealing connection channel is communicated with a pliers lifting steel wire rope through hole in the end seat 6, and the joint of the pliers lifting steel wire rope through hole in the end seat 6 and the steel wire rope in the pliers lifting device 1 is always in a sealing state.
In order not to affect the driving effect of the wire rope 8 of the caliper lifting device on the caliper lifting device 1, the wire rope protecting sleeve 9 of the caliper lifting device is preferably formed by a foldable and telescopic protecting pipe, so that the length of the protecting sleeve 9 can be automatically folded, stretched and adjusted according to the state of the wire rope 8 of the caliper lifting device, and the driving of the wire rope 8 of the caliper lifting device on the caliper lifting device 1 is prevented from being affected.
When the pliers lifting device 1 is driven to lift up, the pliers lifting device driving assembly 7 only needs to rotate the pliers lifting device lifting rod 12 at the operation part of the endoscope, and the steel wire rope driving crank 14 rotates along with the rotation of the pliers lifting device lifting rod 12, so that the steel wire rope driving connecting rod 13 and the steel wire rope driving sliding block 11 are driven to lift up the pliers lifting device 1.
At this time, the protective tube 9 of the wire rope of the lifting clamp sleeved on the wire rope 8 of the lifting clamp between the end seat 6 and the lifting clamp 1 is folded and contracted to shorten the length so as to adapt to the lifting and lowering actions of the lifting clamp 1 (as shown in fig. 8).
Based on the foldable and telescopic protection tube for the steel wire rope of the forceps lifting device, the effect of sealing the steel wire rope cavity channel of the forceps lifting device is achieved, so that the steel wire rope and the tube cavity of the steel wire rope are protected in a sealing mode all the time in the operation and cleaning and disinfection processes, the steel wire rope and the steel wire rope cavity channel are guaranteed not to be polluted, and therefore only the forceps lifting device and the steel wire rope protection tube need to be cleaned and disinfected.
