Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and particularly relates to a guide wire elbow device. Background Art

[0002] A guide wire is a basic instrument in modern endovascular therapy. Procedures such as angiography, thrombectomy, stent placement, and fallopian tube recanalization in modern medicine all rely on the application of guide wires. Interventional therapy is a technique in which specific medical devices such as guide wires and catheters are introduced into the diseased parts of the human body under the guidance of medical imaging equipment for diagnosis and treatment. A guide wire is a commonly used instrument for interventional surgery, and its function is to support, guide, and position other instruments.

[0003] When the guide wire is specifically used, the top end of the guide wire will be bent to form a bent portion as needed. For example, the prior art with the patent application number "CN201921627040.3" provides a double-headed measurable guide wire, including a mandrel, with a coating layer outside the mandrel body. One end of the mandrel is sleeved with a straight-head imaging sleeve, and the other end is a bent structure, on which an elbow imaging sleeve is sleeved. The end faces of the straight-head imaging sleeve and the elbow imaging sleeve are arc surfaces, and the side surfaces are smoothly transitioned with the surface of the coating layer. The present invention can achieve the purpose of using one guide wire as two guide wires. One end is a straight-head soft head, and the other end is an elbow soft head. The elbow soft head has the function of easily entering narrow parts and selectively catheterizing the left and right hepatic ducts. In addition, the guide wire also has the function of length measurement. The guide wire in this prior art has a bent head. However, the existing operation of bending the top end of the guide wire is to manually clamp the top end of the guide wire, and then continuously pull the guide wire after winding it around an axis to make the top end of the guide wire bent and shaped. However, using manual operation not only has low efficiency and high labor costs, but also because the guide wire itself is an elastic and relatively soft structure, so it requires experienced workers to do well in the process of bending the guide wire, which will lead to uneven quality of the finished products produced by manual bending. Summary of the Invention

[0004] In order to solve the above problems, the primary object of the present invention is to provide a guide wire elbow device, which automatically bends the top end of the guide wire after installing the guide wire, without manual operation, not only has higher efficiency, but also can reduce labor costs.

[0005] Another object of the present invention is to provide a guide wire elbow device, and the quality of the finished products produced and processed by this device can be kept consistent, improving the yield rate.

[0006] In order to achieve the above objects, the technical solution of the present invention is as follows.

[0007] A guide wire elbow device, characterized in that the device includes a head fixing mechanism for fixing the head of the guide wire, a pulling mechanism for fixing the guide wire and cooperating with the head fixing mechanism to tighten the guide wire, and a bending mechanism for bending the head of the guide wire; a pulling fixing position for fixing the guide wire is arranged on the pulling mechanism, a head fixing position for fixing the head of the guide wire is arranged on the head fixing mechanism, and a bending position for abutting against the guide wire to cooperate with the pulling mechanism and the head fixing mechanism to bend the head of the guide wire is arranged on the bending mechanism. The shape formed by the three positions of the head fixing position, the bending position and the pulling fixing position is a triangle as a whole. In this device, the head of the guide wire is fixed by the head fixing mechanism, and then the guide wire is bypassed around the bending mechanism and clamped by the pulling mechanism and given a certain pulling force. By maintaining the pulling force, the guide wire is kept taut for a period of time to achieve the bending of its head. Since the above process is realized by a mechanical structure, data such as the fixing force of the head fixing mechanism on the guide wire and the pulling force of the pulling mechanism on the guide wire can be adjusted according to requirements to ensure that they are all data meeting the production requirements; compared with manual operation by workers, it not only has higher efficiency and lower labor cost, but also the quality of the finished products produced by this device can be kept consistent, improving the yield rate.

[0008] Further, the device further includes a guiding mechanism for guiding the guide wire to the bending mechanism, and the guiding mechanism corresponds to the bending position. The guiding mechanism is provided to guide the guide wire when bending the guide wire elbow to ensure that the position of the guide wire is more accurate.

[0009] Further, the bending mechanism includes a rotating shaft and a bending adjustment component for adjusting the position of the rotating shaft. The bending position is located on the rotating shaft, and the rotating shaft is fixedly arranged on the bending adjustment component. The bending adjustment component can adjust the position of the rotating shaft to ensure that the rotating shaft can better cooperate with other structures during production and processing.

[0010] Further, the bending position is a "U"-shaped groove arranged around the rotating shaft; the bending adjustment component includes a rotating shaft seat and a shaft height adjustment head for adjusting the height of the rotating shaft. The shaft height adjustment head is fixedly arranged on the rotating shaft seat, and the shaft height adjustment head is fixedly connected with the rotating shaft; the rotating shaft is made of tungsten steel material. The setting of the "U"-shaped groove facilitates the guide wire to be folded to the correct position on the head fixing mechanism around the rotating shaft, has a certain guiding effect to ensure a better elbow effect. The shaft height adjustment head is a prior art, and it adjusts the position of the rotating shaft by driving the rotating shaft to move up and down, such as a structure preferably similar to the principle of the hand-held rotating part of a micrometer.

[0011] Further, the head fixing mechanism includes a head clamping component for clamping the head of the guide wire and a clamping movement component for driving the head clamping component to move left and right; the head fixing position is located on the head clamping component, and the head clamping component is fixedly arranged on the clamping movement component. The arrangement of the clamping movement component can facilitate the adjustment of the position of the head clamping component and achieve better cooperation with other structures.

[0012] Further, the head clamping component includes an upper head clip, a lower head clip and a clip driving component, and the upper head clip and / or the lower head clip are connected to the clip driving component; the head fixing position is located on the lower head clip, and the upper head clip and the lower head clip are closed or separated under the drive of the clip driving component to fix or release the head of the guide wire; the clip driving component includes a head clip cylinder, and the upper head clip is arranged on the output shaft of the head clip cylinder.

[0013] Further, the head fixing mechanism further includes a head clip seat, the head clip cylinder is fixedly arranged on the head clip seat, an upper clip fixing block is fixedly arranged on the output shaft of the head clip cylinder, and the upper head clip is detachably arranged on the upper clip fixing block; the lower head clip is detachably and fixedly arranged on the head clip seat; through holes are arranged on the sides of both the lower head clip and the upper head clip, and the lower head clip and the upper head clip are respectively detachably arranged on the head clip seat and the upper clip fixing block through the corresponding through holes. The above-mentioned lower head clip and lower head clip can be detachably arranged, so that the device can replace different models of lower head clips and lower head clips according to production requirements.

[0014] Further, the head fixing mechanism further includes a limit ejector pin fixing piece and a limit ejector pin. The limit ejector pin fixing piece is arranged on the lower head clip, the limit ejector pin is fixedly arranged on the limit ejector pin fixing piece, and the limit ejector pin passes through the lower head clip to the head fixing position. The arrangement of the limit ejector pin can limit the head of the guide wire at the head fixing position to prevent the size of the bent part of its head from being too long. And the limit ejector pin fixing piece can also be movably arranged on the lower head clip to control the position of the limit ejector pin at the head fixing position, thereby adjusting the length of the bent head of the guide wire.

[0015] Further, clamping grooves are arranged on both the lower head clip and the upper head clip, and the clamping groove of the upper head clip corresponds to the clamping groove of the lower head clip. After the upper head clip and the lower head clip are closed, the clamping groove of the upper head clip and the clamping groove of the lower head clip form a clamping channel with a diameter smaller than that of the guide wire, and the clamping channel is the head fixing position. Fixing the guide wire through the clamping channel with a diameter smaller than that of the guide wire can not only fix the guide wire, but also prevent the head of the guide wire from being squeezed and deformed.

[0016] Furthermore, the lower head clip is provided with an ejector protrusion, and the upper head clip is provided with a protrusion avoidance position corresponding to the ejector protrusion. The limiting ejector pin passes through the ejector protrusion to the clamping groove of the lower head clip. The cooperation between the ejector protrusion and the protrusion avoidance position prevents the upper head clip from deflecting the ejector pin when the lower head clip and the upper head clip are closed.

[0017] Furthermore, the clamping motion assembly includes a head pulling cylinder, the output shaft of which is fixed to the head clamping assembly to drive the head clamping assembly to move left and right. The head pulling cylinder can pull the clamping assembly to move, thereby achieving preliminary adjustment of the position of the head clamping assembly.

[0018] Furthermore, the clamping motion assembly includes a head-pull length adjustment head, which is fixed to the head clamping assembly to drive the head clamping assembly to move left and right. Adjustment of the length adjustment head allows for more precise adjustment of the position of the head clamping assembly. The head-pull length adjustment head is conventional, preferably having a structure similar in principle to the handheld rotating portion of a micrometer screw.

[0019] Furthermore, a guide channel for guiding the guide wire is provided in the guide mechanism, the tail end of the guide channel corresponds to the bending position, and the head end of the guide channel corresponds to the pulling and fixing position; the head end of the guide channel is arranged in a trumpet-shaped manner; the head end of the guide channel is also provided with a trumpet-shaped expansion piece; and the guide channel as a whole is "J-shaped". The setting of the guide channel and the overall "J-shaped" setting of the guide channel allow the head of the guide wire to be more accurately guided to the rotation axis when the guide wire head is bent. The trumpet-shaped setting of the head end of the guide channel and the trumpet-shaped expansion piece make it easier for the guide wire to enter the guide channel.

[0020] Furthermore, the guiding mechanism includes an upper guiding clamp, a lower guiding clamp and a guiding motion component for controlling the expansion or closure of the upper and lower guiding clamps. The upper guiding clamp and / or the lower guiding clamp are connected to the guiding motion component. The upper guiding clamp and the lower guiding clamp are both provided with guiding grooves. After the upper guiding clamp and the lower guiding clamp are closed, the guiding channel is formed by closing the guiding grooves on the upper guiding clamp and the guide grooves on the lower guiding clamp.

[0021] Furthermore, the guide mechanism also includes an upper guide clamp fixing block and a lower guide clamp fixing block, and the upper guide clamp fixing block and the lower guide clamp fixing block are fixedly arranged on the guide motion component so that the guide motion component drives the upper guide clamp fixing block and the lower guide clamp fixing block to move closer or further away, and the upper guide clamp and the lower guide clamp are detachably arranged on the upper guide clamp fixing block and the lower guide clamp fixing block respectively; the guide motion component includes an upper guide clamp cylinder and a lower guide clamp cylinder, and the upper guide clamp cylinder output shaft and the lower guide clamp cylinder output shaft are fixedly connected to the upper guide clamp fixing block and the lower guide clamp fixing block respectively. The detachable arrangement between the upper guide clamp fixing block, the lower guide clamp fixing block and the upper guide clamp and the lower guide clamp makes it more convenient to disassemble and assemble the upper guide clamp and the lower guide clamp when different models of the upper guide clamp and the lower guide clamp need to be changed.

[0022] Furthermore, the pulling mechanism includes a pulling clamping assembly for clamping and fixing the tail end of the guide wire, and a pulling assembly for pulling the pulling clamping assembly, wherein the pulling fixing position is located on the pulling clamping assembly; the pulling clamping assembly includes a finger cylinder, and the pulling fixing position is located on the finger cylinder; the pulling assembly includes a weight, a bearing seat, a bearing, and a fishing line, wherein the bearing is movably arranged on the bearing seat, one end of the fishing line is connected to the weight, and the other end of the fishing line is connected to the finger cylinder after passing through the bearing, and the weight is suspended in the air and converts gravity into a pulling force on the finger cylinder through the fishing line. The setting of giving the guide wire a pulling force by the weight can reduce costs, and can also achieve a fixed pulling force on the guide wire so that the guide wire can be bent smoothly.

[0023] Furthermore, the pulling mechanism also includes a pulling limit assembly, and the pulling limit assembly includes a first limit piece and a second limit piece, and the first limit piece and the second limit piece are respectively located on the front and rear sides of the pulling clamping assembly to respectively limit the range of forward and backward movement of the pulling clamping assembly; the pulling limit assembly also includes a limit cylinder, and the output shaft of the limit cylinder is fixedly set on the first limit piece to drive the first limit piece to move forward and backward. The setting of the first limit piece can ensure that the finger cylinder prevents the guide wire from being broken due to excessive weight force when working. The second limit piece, combined with the setting of the first limit piece, can prevent the finger cylinder from being out of its position. The setting of the limit cylinder can adjust the position of the first limit piece according to demand.

[0024] The beneficial effects of the present invention are as follows. Compared with the prior art, in the present invention, the head of the guide wire is fixed by the head fixing mechanism, and then the guide wire is bypassed around the bending mechanism and clamped by the pulling mechanism and given a certain pulling force. By maintaining the pulling force, the guide wire is kept taut for a period of time to achieve the bending of its head. Since the above processes are all realized by mechanical structures, data such as the fixing force of the head fixing mechanism on the guide wire and the pulling force of the pulling mechanism on the guide wire can be adjusted according to requirements to ensure that they are all data meeting the production requirements; compared with manual operation by workers, not only is the efficiency higher and the labor cost lower, but also the quality of the finished products produced by this device can be kept consistent, improving the yield rate.

Compared with the prior art, in the present invention, the head of the guide wire is fixed by the head fixing mechanism, and then the guide wire is bypassed around the bending mechanism and clamped by the pulling mechanism and given a certain pulling force. By maintaining the pulling force, the guide wire is kept taut for a period of time to achieve the bending of its head.
