Description

Endoscope lifts pincers ware, endoscope and endoscope system

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an endoscope forceps lifting device. The utility model further relates to an endoscope and an endoscope system comprising the endoscope forceps raising device.

Background

Endoscopes have found widespread use in procedures for examination and treatment of the digestive tract, for example, in Endoscopic Retrograde Cholangiopancreatography (ERCP) procedures, where a duodenoscope is required.

The forceps lifting device belongs to a key part of an endoscope, and comprises a forceps lifting device seat, a rotating arm and a steel wire rope, wherein the rotating arm and the forceps lifting device seat are coaxially fixed and can synchronously rotate, one end of the steel wire rope is connected with an operation assembly of the endoscope, and the other end of the steel wire rope is connected with the rotating arm, so that the steel wire rope pulls the rotating arm and the forceps lifting device seat to rotate by rotating a deflector rod of the operation assembly, thereby changing the extending direction of treatment instruments (such as biopsy forceps or nipple incision knives and other diagnosis and treatment accessories) inserted through a forceps channel from the opening of the forceps channel, and facilitating ultrasonic diagnosis and treatment.

In a gastrointestinal tract examination and treatment operation (e.g., ERCP operation), since an insertion portion of an endoscope enters a human body and directly contacts a damaged mucosa and blood of the human body, the insertion portion needs to be sterilized after the operation. The forceps-lifting device is arranged at the head end of the insertion part and needs to be disinfected and sterilized together with the insertion part.

The inventor finds that because a welding part exists between the connection structure of the steel wire rope and the rotating arm, for example, the steel wire rope can be directly welded with the rotating arm, or the steel wire rope is indirectly connected with the rotating arm through the adapter structure, and the steel wire rope is welded with the adapter structure, when the sterilization and disinfection of the lifting clamp device are carried out, the welding position existing at the connection part between the steel wire rope and the rotating arm needs to be considered most, because the lifting clamp device is usually sterilized by soaking in peroxyacetic acid solution at present, the welding position is easy to lose efficacy after being soaked in peroxyacetic acid solution for a long time, and the transmission between the steel wire rope and the rotating arm fails.

In summary, how to avoid the failure of the welding position between the steel wire rope and the rotating arm due to the long-term soaking in the sterilization solution is a problem to be solved urgently by those skilled in the art.

Specifically, the adaptor 3 is welded to one end of the steel wire rope 2, and as known to those skilled in the art, the other end of the steel wire rope 2 is connected to the operating assembly 100 of the endoscope, so that the steel wire rope 2 pulls the rotating arm 1 to rotate under the action of the shift lever 101 of the operating assembly 100 of the endoscope.

The protection piece 4 is respectively connected with the steel wire rope 2 and the adapter piece 3, so that the protection piece 4 is hermetically covered on the welding position of the adapter piece 3 and the steel wire rope 2, namely, the protection piece 4 is adopted to protect the welding position of the adapter piece 3 and the steel wire rope 2 from being exposed outside, and when a sterilization solution (such as a peracetic acid solution) is adopted to soak and sterilize the pliers lifting device, the sterilization solution (such as the peracetic acid solution) can be prevented from entering the welding position of the adapter piece 3 and the steel wire rope 2, so that the welding position of the adapter piece 3 and the steel wire rope 2 can be prevented from being directly contacted with the sterilization solution (such as the peracetic acid solution), the welding position of the adapter piece 3 and the steel wire rope 2 is prevented from being failed due to long-time soaking of the sterilization solution (such as the peracetic acid solution), and the effectiveness and reliability of connection between the steel wire rope 2 and the adapter piece 3 are ensured.

Further, the protection member 4 is connected to the boom 1, and since the protection member 4 is simultaneously connected to the adaptor 3 and the wire rope 2, respectively, and the wire rope 2 is welded to the adaptor 3, the force of the wire rope 2 acting on the adaptor 3 can be transmitted to the boom 1 through the protection member 4, so that the wire rope 2 can pull the boom 1 to rotate.

Therefore, the endoscope forceps raising device provided by the utility model has the advantages that the adapter 3 and the protection piece 4 are additionally arranged, the force and the movement of the steel wire rope 2 are transmitted to the rotating arm 1 by utilizing the switching action of the adapter 3 and the protection piece 4, and the rotating of the rotating arm 1 is realized. Meanwhile, the welding position between the adaptor 3 and the steel wire rope 2 is protected by the protection piece 4, and the welding position is prevented from being exposed under the condition that the steel wire rope 2 is exposed, namely, the welding position is not contacted with a sterilization solution (such as a peracetic acid solution) during sterilization, so that the welding position between the adaptor 3 and the steel wire rope 2 can be prevented from being corroded during sterilization no matter what welding form is adopted to realize the welding between the adaptor 3 and the steel wire rope 2, therefore, the welding between the adaptor 3 and the steel wire rope 2 can be realized by adopting welding modes such as silver welding and the like, and the performance of the steel wire rope 2 is ensured not to be influenced by a welding process; meanwhile, the steel wire rope 2 is exposed outside, so that sterilization is facilitated, dead angles of decontamination can be avoided, residual of stains and germs can be effectively avoided, and the reliability of sterilization is ensured; in addition, the welding position of the adaptor 3 and the steel wire rope 2 is not contacted with a sterilization solution (such as a peracetic acid solution) during sterilization, so that the welding position cannot be corroded when the sterilization solution (such as the peracetic acid solution) is used for soaking and sterilizing the forceps lifting device for a long time, mechanical failure of the forceps lifting device due to the fact that the forceps lifting device is soaked by the sterilization solution (such as the peracetic acid solution) for a long time is avoided, and the forceps lifting device is good in sterilization resistance.

As shown in fig. 3 and 4, in consideration of convenience of connection between the steel cable 2 and the adapter 3, in order to facilitate limiting the end of the steel cable 2, on the basis of the above embodiment, the adapter 3 is provided with a first mounting hole, and one end of the steel cable 2 is inserted into the first mounting hole. That is to say, this embodiment sets up first mounting hole through adapter 3 and carries on spacingly to wire rope 2's tip to wire rope 2 and adapter 3 welded fastening are convenient for.

It should be noted that, in this embodiment, a specific welding position of the steel wire rope 2 and the adaptor 3 is not limited, for example, after one end of the steel wire rope 2 is inserted into the first mounting hole, the steel wire rope 2 and an end face of the opening of the first mounting hole may be welded and fixed.

In order to improve the welding strength between the steel wire rope 2 and the adaptor 3, as a preferable scheme, on the basis of the above embodiment, a gap is formed between the first mounting hole and the steel wire rope 2, and the gap is filled with solder. That is to say, in this embodiment, the first mounting hole is in clearance fit with the steel wire rope 2, and the gap between the first mounting hole and the steel wire rope 2 is filled with solder, so that the inner wall of the first mounting hole and the outer peripheral portion of the steel wire rope 2 extending into the first mounting hole are welded and fixed, which is beneficial to increase the welding area and improve the welding strength between the steel wire rope 2 and the adaptor 3.

In addition, in order to increase the welding strength between the steel wire rope 2 and the adaptor 3, in the above embodiment, a hole 31 (as shown in fig. 3) penetrating through the thickness of the side wall of the first mounting hole may be formed, and the first mounting hole is filled with solder. That is, in the present embodiment, the hole 31 is formed in the side wall of the first mounting hole, and the solder is filled in the hole 31, so that the steel wire rope 2 is welded to the first mounting hole. It can be understood that the larger the number of the holes 31 formed in the side wall of the first mounting hole, the more welding points between the steel cable 2 and the adapter 3 are, so that the connection strength between the steel cable 2 and the adapter 3 is higher. It should be noted that, in the embodiment, the specific number of the holes 31 and the specific size of the holes 31 are not limited, and a person skilled in the art can reasonably design the number and the size of the holes 31 according to the strength requirement of the adapter 3 itself and the welding strength requirement between the steel wire rope 2 and the adapter 3. Preferably, when the number of the holes 31 is at least two, more than two holes 31 are uniformly distributed along the circumferential direction of the first mounting hole.

Further, in order to make the connection between the steel wire rope 2 and the adaptor 3 more secure, the steel wire rope 2 and the adaptor 3 may be welded in the above two manners, that is, a gap is formed between the first mounting hole and the steel wire rope 2, the gap is filled with solder, and meanwhile, a hole 31 penetrating the thickness of the first mounting hole is formed in a side wall of the first mounting hole, and the hole 31 is filled with solder. This can further increase the welding area, promote the joint strength between wire rope 2 and adaptor 3.

In each of the above embodiments, the specific shape of the first mounting hole is not limited, and preferably, the first mounting hole is a circular hole. In addition, the first mounting hole may be a through hole or a blind hole, which is not limited to this, and as a preferable mode, as shown in fig. 4, in addition to the above embodiment, the first mounting hole is a blind hole. That is, the first mounting hole does not completely penetrate through the adaptor 3, and the bottom of the first mounting hole is sealed, so that the structure of the adaptor 3 can be utilized to seal one end of the first mounting hole, and the welding position between the steel wire rope 2 and the adaptor 3 is prevented from being exposed from the bottom of the first mounting hole, that is, at the moment, the adaptor 3 has a certain protection effect, and the protection piece 4 can be assisted to better prevent the welding position between the steel wire rope 2 and the adaptor 3 from being exposed. Moreover, the structure is simple and convenient to process.

In the above embodiments, the specific connection mode of the protector 4 to the wire rope 2 and the adaptor 3 is not limited, and the protector 4 may be hermetically covered on the welding position between the adaptor 3 and the wire rope 2 after the protector 4 is connected to the wire rope 2 and the adaptor 3, respectively.

Preferably, on the basis of the above embodiment, the protection component 4 is provided with the sleeving holes 41, and the sleeving holes 41 are respectively and hermetically sleeved with the adaptor 3 and the steel wire rope 2 located outside the adaptor 3. It will be appreciated that, in view of convenience of connection, it is preferable that the socket hole 41 be socket-connected to the adaptor 3 while the socket hole 41 be socket-connected to a portion of the wire rope 2 located outside the adaptor 3 and near the adaptor 3, as shown in fig. 4.

In addition, in this embodiment, the sealing manner between the socket hole 41 and each of the adaptor 3 and the wire rope 2 is not limited, and for example, the socket hole 41 and the adaptor 3 and the socket hole 41 and the wire rope 2 may be sealed by a mechanical labyrinth structure in which concave and convex portions are fitted.

In view of the simplicity of the structure and the convenience of sealing, as a preferable scheme, on the basis of the above embodiment, the socket hole 41 and the adaptor 3 are connected in a sealing manner by an adhesive or a sealing ring; and/or, the sleeving hole 41 is connected with the steel wire rope 2 in a sealing mode through an adhesive or a sealing ring. For example, gaps are respectively formed between the socket hole 41 and the adaptor 3 and between the socket hole 41 and the steel wire rope 2, and the adhesive can be filled in the gaps to realize the adhesive fixation between the socket hole 41 and the adaptor 3 and between the socket hole 41 and the steel wire rope 2, so that the adhesive has the function of preventing liquid from entering between the socket hole 41 and the adaptor 3 and between the socket hole 41 and the steel wire rope 2 while realizing the fixation, and a sterilization solution (such as a peracetic acid solution) is prevented from entering the welding position between the adaptor 3 and the steel wire rope 2 from between the socket hole 41 and the adaptor 3 and/or between the socket hole 41 and the steel wire rope 2 during sterilization. In the present embodiment, the specific material of the adhesive is not limited, and the adhesive is preferably a non-metal adhesive, for example, an adhesive. Of course, a person skilled in the art can realize the sealing connection between the socket hole 41 and the adaptor 3 and/or between the socket hole 41 and the steel wire rope 2 by using a sealing ring through a reasonable structural design, and can also achieve the fixing and sealing effects.

It should be noted that the socket hole 41 may be a straight hole with a uniform diameter, or may be a hole with other shapes, and in consideration of the positioning problem when the protection component 4 is installed, on the basis of the above embodiment, the socket hole 41 includes the first socket hole 411 and the second socket hole 412, the first socket hole 411 is socket-connected with the adaptor 3, the second socket hole 412 is socket-connected with the steel wire rope 2, and the first socket hole 411 and the second socket hole 412 form a stepped hole, and a stepped surface at a connection position of the two holes is in contact with an end surface of the adaptor 3. That is, in the present embodiment, the sleeve hole 41 is configured as a stepped hole, so as to facilitate positioning of the protection component 4 when the protection component is installed, that is, as shown in fig. 3, the protection component 4 is sleeved into the steel wire rope 2 from one end of the steel wire rope 2 away from the adaptor 3, and moves along the steel wire rope 2 to a position matched with the adaptor 3, when the protection component 4 moves to a position where a step surface at a connection position of the first sleeve hole 411 and the second sleeve hole 412 is in contact with an end surface of the adaptor 3, the protection component 4 cannot move further due to a stopping function of the end surface of the adaptor 3, which indicates that the protection component 4 is installed in place. In addition, it can be understood that, when the steel wire rope 2 is inserted into the first mounting hole of the adaptor 3, the size of the outer peripheral portion of the adaptor 3 is larger than the outer diameter size of the steel wire rope 2, so that the socket hole 41 in the form of a stepped hole is further beneficial to enabling appropriate fit clearances to be formed between the socket hole 41 and the steel wire rope 2 and between the socket hole 41 and the adaptor 3, and enabling the socket hole 41 to have reliable connection strength with the steel wire rope 2 and the adaptor 3 respectively.

In consideration of the convenience of processing, on the basis of the above embodiment, the first engaging hole 411 is a circular hole, and the outer peripheral portion of the adaptor 3 is a cylindrical surface. It will be appreciated that both the cylindrical surface and the circular aperture facilitate continuous machining, which provides some ease in the manufacture of the adaptor 3 and the guard 4. In addition, the cylindrical surface is matched with the circular hole, so that the uniformity of the gap between the first sleeving hole 411 and the adaptor 3 is ensured, and the balance of the connection strength between the protection piece 4 and the adaptor 3 is ensured.

In the same way, it can be understood that, since the outer peripheral portion of the steel cable 2 is cylindrical, in order to facilitate the connection between the steel cable 2 and the second socketing hole 412, preferably, the second socketing hole 412 is a round hole, which is convenient for processing on the one hand, and is beneficial to ensure the uniformity of the gap between the second socketing hole 412 and the steel cable 2 on the other hand, and ensure the balance of the connection strength between the protection piece 4 and the steel cable 2.

In addition, in order to facilitate the attachment of the protector 4 and the adaptor 3, as another preferable mode, in the above embodiment, the first fitting hole 411 is a conical hole, and the outer peripheral portion of the adaptor 3 is a conical surface. It will be appreciated that the small end of the conical surface faces towards the cable 2 and the large end of the conical surface faces away from the cable 2, otherwise the mounting of the guard 4 will not be possible. When the protection member 4 is installed, when the protection member 4 moves to the position of the adaptor 3 along the steel wire rope 2, the large end of the first sleeving hole 411 firstly enters the small end of the adaptor 3, so that the protection member 4 can be smoothly sleeved on the adaptor 3, and simultaneously, as the protection member 4 is continuously sleeved on, the protection member 4 can be smoothly sleeved on the position under the guiding effect of the conical surface of the adaptor 3.

In the above-described respective embodiments, the concrete manner of connecting the guard 4 to the boom 1 is not limited, and for example, the guard 4 may be fixedly connected to the boom 1 directly as long as the guard 4 can transmit the force of the wire rope 2 to the boom 1. In addition, in order to enlarge the angle of movement of the wire rope 2 and to prevent the wire rope 2 from being damaged by being bent too much at a position close to the protector 4, the protector 4 is pivotally connected to the boom 1 in the above embodiment. That is, in the present embodiment, when the cable 2 is moved, the protection member 4 is driven to rotate relative to the rotating arm 1, so that the moving range of the cable 2 can be expanded, and the cable 2 is prevented from being bent too much, and thus the cable 2 is prevented from being damaged due to bending too much. Meanwhile, since the protection member 4 is connected to the boom 1, the protection member 4 can rotate the boom 1 as a whole by pulling the wire rope 2. That is, in the present embodiment, the guard 4 is rotatable together with the boom 1 while the guard 4 is rotated relative to the boom 1.

It should be noted that the present embodiment does not limit the specific rotation connection structure between the protection member 4 and the rotation arm 1, the relative rotation direction between the protection member 4 and the rotation arm 1, and the like, and for example, the protection member 4 is preferably ball-hinged to the rotation arm 1. That is, the prevention piece 4 is connected to the boom 1 by a ball hinge so that the prevention piece 4 can be rotated in any direction with respect to the boom 1.

In view of the specific structural requirements, as a preferable solution, on the basis of the above-described embodiment, as shown in fig. 1 and 2, the outer peripheral portion of the protection member 4 is a cylindrical surface, and the swivel arm 1 is provided with a second mounting hole 11 for rotatably coupling with the outer peripheral portion of the protection member 4. That is, in the present embodiment, the shaft holes are engaged with each other, so that the protector 4 is rotated in the second mounting hole 11 around the axis of the outer peripheral portion thereof in a direction perpendicular to the axis of the second mounting hole 11, and the rotation of the protector 4 in the second mounting hole 11 enlarges the range of movement of the wire rope 2, thereby preventing the wire rope 2 from being bent excessively.

It will be appreciated that when one end of the wire rope 2 is inserted into the first mounting hole of the adaptor 3, it is preferable that the axis of the outer peripheral portion of the protector 4 is arranged perpendicular to the axis of the first mounting hole, which would otherwise reduce the effect of expanding the range of motion of the wire rope 2, and particularly, when the axis of the outer peripheral portion of the protector 4 coincides with the axis of the first mounting hole, which would not act to expand the range of motion of the wire rope 2.

It should be noted that, in the above embodiments, specific materials of the adaptor 3 and the shielding member 4 are not limited, and it is understood that both the adaptor 3 and the shielding member 4 can be soaked in a sterilization solution (such as a peracetic acid solution) for a long time without being damaged, that is, both the adaptor 3 and the shielding member 4 have better corrosion resistance. Preferably, the adaptor 3 and the shield 4 are both metal pieces.

In addition to the above-mentioned endoscope forceps-lifting device, the present invention further provides an endoscope, which includes a forceps-lifting device, where the forceps-lifting device is the endoscope forceps-lifting device disclosed in any of the above-mentioned embodiments, and the structure of other parts of the endoscope is referred to the prior art, and will not be described herein again.

Wherein, the light guide hose 400 is connected between the light guide assembly 300 and the operation assembly 100; the insertion assembly 200 comprises an insertion tube 201, a curved portion 202 and a head portion 203, the insertion tube 201 is connected to the operation assembly 100 at one end and to the curved portion 202 at the other end, and the insertion tube 201 is preferably graduated; the bending part 202 can realize swinging in different directions; the head part 203 is arranged at one end of the bending part 202 far away from the insertion tube 201 and used for feeding back diagnosis information, the head part 203 integrates functions of illumination, image transmission, water and gas delivery, and operation of a channel instrument, the head part 203 is provided with a clamp lifting device, the clamp lifting device comprises a clamp lifting seat 5, a rotating arm 1 and a steel wire rope 2, the clamp lifting seat 5 and the rotating arm 1 are preferably coaxially fixed through a pin 6 so as to realize synchronous rotation of the two, the steel wire rope 2 is connected with the operation assembly 100 so as to control the clamp lifting seat 5 and the rotating arm 1 to rotate by operating a deflector rod 101 of the operation assembly 100 (as shown in figure 6, wherein the arrow direction in figure 6 is the rotating direction of the deflector rod 101), so that the extending direction of a treatment instrument (as shown in figure 7, wherein the arrow direction in figure 7 is the rotating direction of the treatment instrument) inserted through the channel from the port is changed, to facilitate ultrasonic diagnosis and treatment.

It should be noted that the present embodiment focuses on the use of the endoscope forceps raising device disclosed in any of the above embodiments, as shown in fig. 8. Because the welding position of the endoscope forceps raising device cannot be corroded when the endoscope forceps raising device is soaked in a sterilization solution (such as a peracetic acid solution) for a long time, the transmission effectiveness between the steel wire rope 2 and the rotating arm 1 can be ensured, and the endoscope forceps raising device has good sterilization resistance; and the welding form between the steel wire rope 2 and the adapter piece 3 of the endoscope forceps lifting device is not limited, so that the connection strength of the steel wire rope 2 and the adapter piece 3 can be ensured, and the performance of the steel wire rope 2 is ensured. Therefore, the endoscope adopting the endoscope forceps lifting device has better sterilization resistance and sterilization reliability.
