Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a detection device for a clip applier. Background Art

[0002] Clip applicators are a medical device commonly used in surgical operations. They have good corrosion resistance and durability. They are mainly used to clamp and place various types of clips, such as hemostatic clips, ligation clips, etc. The design of clip applicators usually takes ergonomics into consideration so that doctors can operate them easily and accurately.

[0003] There are many types of clip applicators, and their shapes, sizes, and functions may vary depending on different surgical needs and operating scenarios. During the manufacturing process, strict precision and quality standards need to be met to ensure their reliability and safety during surgery, so clip applicators need to be tested to ensure their quality and performance.

[0004] The clamp applicator is placed on the detection device during detection. The detection mechanism of the detection device is connected to the jaw portion of the clamp applicator. The clamping end of the clamp applicator is rotated to rotate the jaw at the front end of the clamp applicator, so that the detection mechanism detects the clamping force and flexibility of the clamp applicator.

[0005] When inspecting the clip applier, the clip applier detection device in the prior art cannot detect whether the left and right jaws are symmetrical to achieve uniform and effective clamping, thus causing limitations.

[0006] Therefore, we propose a detection device for a clip applier. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: Refer to the attached specification Figure 1 , 2 , 4 and 6, a detection device for a clip applier, comprising:

[0034] Base 1, fixed base 2, moving block 3 and detection pressure sensor; the fixed base 2 is fixedly connected to the base 1, and a fixed block 21 is rotatably connected to the fixed base 2; a contact block 22 is slidably connected in the fixed block 21, and a spring is connected between the fixed block 21 and the contact block 22; a push electric push rod 23 is hinged on the fixed base 2; the output end of the push electric push rod 23 is hinged to the moving block 3;

[0035] The movable block 3 is slidably connected to the fixed seat 2, and the movable block 3 can squeeze the handheld end of the clamp; the fixing seat 2 is symmetrically slidably connected with the mounting block 4; the detection pressure sensor is fixedly connected to the mounting block 4; the detection pressure sensor is fixedly connected to a detection spring 41; the end of the detection spring 41 away from the detection pressure sensor is fixedly connected to a connecting block 42; a connecting unit is provided on the connecting block 42, which is connected to the outer side of the jaws of the clamp.

[0036] In the present invention, the connecting unit includes a piston block 5, a pulling screw 51 and an arc-shaped piece 52; a piston groove 53 is opened in the connecting block 42; the piston block 5 is slidably connected in the piston groove 53; the pulling screw 51 and the connecting block 42 are threadedly matched, and the pulling screw 51 and the piston block 5 are rotationally connected; the arc-shaped piece 52 is installed on the connecting block 42, and a sealing layer 54 is fixed to the arc-shaped piece 52, and the arc-shaped piece 52 and the piston groove 53 are connected through a connecting pipe 55.

[0037] In the present invention, the arc-shaped piece 52 is rotatably connected to the connecting block 42 .

[0038] In the present invention, the person in charge places the clamp in the groove on the fixing seat 2, and then rotates the fixing block 21 so that the contact block 22 on the fixing block 21 contacts the clamp, and squeezes the clamp so that the clamp is fixed. Then the staff moves the mounting block 4 so that the arc pieces 52 on the connecting blocks 42 on both sides of the clamp contact and fit with the outer side of the clamp jaws, and then rotates the pulling screw 51 so that the pulling screw 51 pulls the piston block 5 outward, so that the air pressure in the piston groove 53 is reduced, and the air pressure between the arc piece 52 and the clamp jaws is connected to the piston groove 53 through the connecting pipe 55, so that the arc piece 52 and the outer side of the clamp jaws are firmly sucked, and the sealing layer 54 prevents air pressure leakage, so that the connecting block 42 is connected to the outer side of the clamp jaws.

[0039] Pushing the electric push rod 23 drives the moving block 3 to move, so that the moving block 3 moves with the handle of the clamp, and the jaws of the clamp open or close accordingly. In this process, the jaws of the clamp drive the connecting block 42 to move, thereby stretching the detection spring 41 and transmitting the tension to the detection pressure sensor, so as to detect the clamping force and flexibility of the clamp. In addition, detection pressure sensors are provided on both sides of the clamp jaws, so as to detect whether the clamp jaws are symmetrical when clamping.

[0040] In the present invention, the arc-shaped piece 52 is rotatably connected to the connecting block 42. When the jaws of the clamp are opened or closed, the arc-shaped piece 52 can rotate with the movement of the jaws of the clamp, thereby preventing the jaws of the clamp and the arc-shaped piece 52 from being separated due to uneven force when the jaws of the clamp are opened or closed.

[0041] The present invention arranges detection pressure sensors on both sides of the jaws of the clamp and connects them to the outside of the jaws of the clamp via a connecting unit. Thus, when the jaws of the clamp move, the present invention can detect whether the jaws of the clamp are symmetrical on the left and right when clamping. The connecting portion of the connecting unit and the clamp is on the outside of the clamp, which does not affect the closing of the clamp.

[0042] Refer to the instruction manual Figure 1 ,3 , 4 and 7, in the present invention, the mounting block 4 is fixedly connected with the height pressure sensor 6; the height pressure sensor 6 is fixedly connected with the V-shaped spring piece 61; the V-shaped spring piece 61 is in contact with the connecting block 42.

[0043] In the present invention, an adjusting block 7 is slidably connected to the fixed seat 2; a telescopic block 71 is slidably connected to the adjusting block 7, and a telescopic electric push rod 72 is fixedly connected to the adjusting block 7; the output end of the telescopic electric push rod 72 is fixedly connected to the telescopic block 71; a vertical detection groove 73 is opened on the telescopic block 71; a conical block 74 is slidably connected in the vertical detection groove 73, and a vertical pressure sensor 75 is fixedly connected in the vertical detection groove 73; a vertical spring 76 is fixedly connected between the vertical pressure sensor 75 and the conical block 74.

[0044] In the present invention, the V-shaped spring piece 61 on the height pressure sensor 6 contacts the connecting block 42, thereby transmitting the pressure to the height pressure sensor 6. When the jaws of the clamp applicator are staggered up and down when closed or opened, the up and down positions of the two connecting blocks 42 also change, so that the pressure transmitted to the two height pressure sensors 6 on both sides also changes. Therefore, the present invention can detect whether the jaws of the clamp applicator are staggered up and down or shaken.

[0045] In the present invention, the adjusting block 7 is moved so that the front end of the conical block 74 is located in the middle of the jaws of the clamp. When the moving block 3 moves with the handle end of the clamp to close the jaws of the clamp, the telescopic electric push rod 72 drives the telescopic block 71 to move so that the conical block 74 moves toward the direction close to the jaws of the clamp, and the conical block 74 contacts the jaws of the clamp; when there is a gap in the jaws, the conical block 74 is inserted into the gap in the jaws of the clamp, so that the depth of the conical block 74 changes, and the pressure transmitted to the vertical pressure sensor 75 is reduced. Therefore, the present invention can detect whether the jaws of the clamp can be completely closed.

[0046] The present invention sets a height pressure sensor 6 and a V-shaped spring piece 61 to detect whether the jaws of the clamp are staggered or shaking. The present invention detects whether the jaws of the clamp are completely closed by measuring the depth of movement of the conical block 74 after contact with the jaws of the clamp, thereby improving the detection range of the present invention.

[0047] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 2 and 5 In the present invention, extrusion grooves 8 are evenly spaced apart on the moving block 3; a pair of extrusion blocks 81 are slidably connected in the extrusion grooves 8; and an extrusion column 82 is fixedly connected to the extrusion block 81.

[0048] In the present invention, a fixing groove 83 is provided on the moving block 3; the fixing groove 83 is connected to the extrusion groove 8, a support block 84 is slidably connected in the fixing groove 83, and a spring of the extrusion block 81 is fixedly connected in the fixing groove 83; the extrusion block 81 spring is fixedly connected to the support block 84; the fixing groove 83 passes through the moving block 3, so that the support block 84 is exposed from the moving block 3.

[0049] In the present invention, the staff presses the support block 84 downward to make the squeezing block 81 disengage from the support block 84, and then moves the squeezing block 81 and the squeezing column 82 to make the two squeezing columns 82 in the same squeezing groove 8 be located on both sides of the handle of the clamp applicator to clamp the handle, and then stops pressing the support block 84 to make the support block 84 contact with the squeezing block 81, and fixes the squeezing block 81 under the squeezing of the support block 84, and then moves the block 3 to drive the handle of the clamp applicator to move by driving the squeezing column 82;

[0050] The present invention arranges the squeezing block 81 and the squeezing column 82 so that the squeezing column 82 is located on both sides of the handle of the clip applier. Thus, the present invention can be applied to clip appliers with handles of different sizes and shapes, thereby improving the detection range of the present invention.
