Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a clamping device, a clamp applicator, and a clamp delivery monitoring method. Background Technology

[0002] During surgical procedures, to fully expose the surgical field, it is necessary to ligate the blood vessels surrounding the target tissue to stop bleeding. Hemostasis has become one of the core basic surgical techniques. Almost every surgical procedure on any part of the human body involves bleeding and hemostasis, and generally, a clamping device is used to ligate and close the hemostasis.

[0003] like Figures 1 to 4 As shown, the clamp applicator includes a clamping device 1 and a handle 2, with the clamping device 1 detachably mounted on the handle 2. The clamping device 1 includes a clamping chamber 12 for accommodating multiple ligation clips 11 and a pushing clip 13 for pushing the ligation clips 11. The multiple ligation clips 11 include a ligation clip to be inserted into the clamp jaws (i.e., a ligation clip 11 to be inserted into the clamp jaws) located at the farthest end of the clamping chamber 12 and ligation clips to be delivered arranged and stored near the ligation clip to be inserted into the clamp jaws. The clamping chamber 12 includes a clamping chamber base plate and first and second side walls connected to the clamping chamber base plate, arranged sequentially from left to right. The multiple ligation clips 11 are placed flat on the clamping chamber base plate with their openings facing the clamping direction. The first clamping arm of the ligation clip 11 is in contact with the first side wall, and the second clamping arm of the ligation clip 11 is in contact with the second side wall. Multiple first elastic locking positions 122, which are evenly spaced along the clamping direction and tilted upwards, are provided on the clamping chamber base plate. The clip 13 includes a push clip 13 body and a push clip 13 head connected in sequence. The push clip 13 head is bent downward relative to the push clip 13 body. The push clip 13 body covers the ligation clip to be delivered. The push clip 13 head extends into the clamping chamber 12 and is positioned close to the ligation clip to be delivered. Multiple second elastic locking positions 131 that are evenly spaced on the push clip 13 body and tilted downward along the clamping direction are provided. The ligation clip 11 includes a V-shaped ligation clip body. The free end of the first clamping arm is provided with a first support column 111 that extends upward from the upper end of the V-shaped ligation clip body and downward from the lower end of the V-shaped ligation clip body. The free end of the second clamping arm is provided with a second support column 112 that extends upward from the upper end of the V-shaped ligation clip body and downward from the lower end of the V-shaped ligation clip body.

[0004] Before the clamping device 1 delivers the clamp, the first support column 111 and the second support column 112 of the clamp to be inserted are both located on the far side of the farthest first elastic locking position 122. The first support column 111 and the second support column 112 of the clamp to be delivered are both located between two adjacent first elastic locking positions 122, and one clamp to be delivered is accommodated between two adjacent first elastic locking positions 122. The second elastic locking position 131 is located between the support columns of two adjacent clamps to be delivered. When the clamping device 1 delivers the clamp, the push clamp 13 moves towards the far end of the clamping chamber 12, and the raised part of the second elastic locking position 131 gradually abuts against the first support column 111 and / or the second support column 112 of the clamp to be delivered, while the head of the push clamp 13 abuts against the tail of the clamp to be inserted. As the pusher clip 13 continues to advance towards the distal end of the clamping chamber 12, it pushes all the ligation clips 11 towards the distal end of the clamping chamber 12 until the ligation clip to be inserted into the jaws. The pusher clip 13 then stops advancing towards the distal end of the clamping chamber 12. During this process, the ligation clip to be inserted will pass its adjacent first elastic locking position 122. Next, the pusher clip 13 advances towards the proximal end of the clamping chamber 12. The head of the pusher clip 13 and the second elastic locking position will drive the ligation clip to be inserted towards the proximal end of the clamping chamber 12. When the ligation clip to be inserted contacts the first elastic locking position 122, the first elastic locking position 122 will block the ligation clip from continuing to advance towards the proximal end of the clamping chamber 12. Because the head of the pusher clip 13 and the second elastic locking position 131 are elastic, the head of the pusher clip 13 and the second elastic locking position 131 will pass their adjacent ligation clips 11. After that, the pusher clip 13 stops advancing towards the proximal end of the clamping chamber 12. The pusher clip 13 moves back and forth in this way, sending the ligation clip 11 to the jaws one by one.

[0005] In the clamping device 1 configured as described above, during the clamping process, some clamps to be delivered may only move above their adjacent first elastic locking position 122 without being able to pass it. This can lead to clamping jamming during subsequent operation of the clamping device 1. Continuing to deliver clamps while they are jammed will damage the drive structure of the handle 2 and reduce its service life. Therefore, how to promptly detect situations where clamps to be delivered cannot pass their adjacent first elastic locking position 122 has become an urgent problem to be solved. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] In view of the problems existing in the above-mentioned technologies, the present invention provides solutions to at least some extent. Therefore, the first objective of the present invention is to provide a clamping device that provides a structural basis for realizing clamping monitoring.

[0008] A second objective of the present invention is to provide a clamping device having the above-described clamping mechanism.

[0009] The third objective of this invention is to propose a clamp delivery monitoring method based on the above-mentioned clamp applicator, which can promptly detect situations where the clamp to be delivered cannot cross its adjacent first elastic locking position during the clamp delivery process.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0012] In a first aspect, the present invention proposes a clamping device, comprising a clamping chamber, a ligation clip to be delivered located between two adjacent first elastic clamping positions within the clamping chamber, and a first communication interface for communication connection with a handle; when the ligation clip to be delivered is not acted upon by the push clamp, each ligation clip to be delivered can move between a first position and a second position; each ligation clip is equipped with a magnet, and when the ligation clip to be delivered is not acted upon by the push clamp, the magnet of each ligation clip to be delivered can move from the first position to the second position, and a Hall linear element is provided on the bottom plate of the clamping chamber in the middle of the movement trajectory of the magnet of each ligation clip to be delivered from the first position to the second position, and all Hall linear elements are electrically connected to the first communication interface.

[0013] Optionally, the Hall linear element is a surface-mount Hall linear element.

[0014] Optionally, each ligation clip is fitted with a magnet at its tail, and a Hall linear element is positioned at the distal end of the first elastic clip.

[0015] Secondly, the present invention proposes a clamp applicator, including a handle and a clamping chamber device as described above connected to the handle; the clamping chamber device further includes: a memory for storing information on the number of clamps in the clamping chamber, information on the arrangement order of Hall linear elements in the clamping chamber device, and a pre-calibrated clamping voltage range for the Hall linear elements; the handle includes: a second communication interface for connecting to a first communication interface; a controller electrically connected to the second communication interface for updating the number of clamps stored in the memory after each clamping operation and before the next clamping operation, determining the Hall linear elements to be judged in the clamping chamber device based on the updated number of clamps in the memory and the arrangement order information of the Hall linear elements, and determining whether the clamping operation is normal based on the pre-calibrated clamping voltage range and the detection voltage value of the Hall linear elements to be judged.

[0016] Optionally, the controller is used to select, starting from the farthest Hall linear element in the clamping compartment and moving from farthest to near, one less Hall linear element than the number of clamps as the Hall linear element to be judged, based on the number of clamps updated in the memory.

[0017] Optionally, the controller is used to determine whether there is a detection voltage value of the Hall linear element to be judged that does not fall within the pre-calibrated clamping voltage range, based on the pre-calibrated clamping voltage range and the detection voltage value of the Hall linear element to be judged. If such a value exists, the clamping operation is abnormal; if not, the clamping operation is normal.

[0018] Optionally, the controller is also used to determine, before the first clamp feeding, the target number of Hall linear elements whose detected voltage values ​​fall within the pre-calibrated clamp feeding voltage range based on the pre-calibrated clamp feeding voltage range and the detected voltage values ​​of all Hall linear elements. If the target number plus one is consistent with the number of clamps stored in the memory, then the number of clamps stored in the memory is correct. If the target number plus one is inconsistent with the number of clamps stored in the memory, then the number of clamps stored in the memory is incorrect, and the number of clamps stored in the memory is corrected based on the value after the target number plus one.

[0019] Optionally, the handle also includes: a prompting unit for outputting an alarm signal; the controller is also used to instruct the prompting unit to output an alarm signal when the clamping operation is abnormal.

[0020] Thirdly, the present invention provides a clamping monitoring method, comprising the following steps:

[0021] S1. After each clamp feeding is completed and before the next clamp feeding, update the clamp quantity information stored in the memory;

[0022] S2. Obtain the updated clamp quantity information from the memory, the arrangement order information of the Hall linear elements in the clamping device, and the pre-calibrated clamping voltage range of the Hall linear elements. Based on the updated clamp quantity from the memory and the arrangement order information of the Hall linear elements, determine the Hall linear elements to be judged in the clamping device. Based on the pre-calibrated clamping voltage range and the detection voltage value of the Hall linear elements to be judged, determine whether the clamping operation is normal.

[0023] Optionally, the following steps may be included before S1:

[0024] S0. Before the first clamping, based on the pre-calibrated clamping voltage range and the detection voltage values ​​of all Hall linear elements, determine the target number of Hall linear elements whose detection voltage values ​​fall within the pre-calibrated clamping voltage range. If the target number plus one is consistent with the number of clamps stored in the memory, then the number of clamps stored in the memory is correct. If the target number plus one is inconsistent with the number of clamps stored in the memory, then the number of clamps stored in the memory is incorrect, and the number of clamps stored in the memory is corrected based on the value after the target number plus one.

[0025] (III) Beneficial Effects

[0026] The beneficial effects of this invention are:

[0027] The clamping device provided by this invention, by pre-calibrating the detection voltage range of the Hall linear element during the normal clamping process of the magnet of the ligation clip to be delivered moving from the first position to the second position, can compare the voltage value detected by each Hall linear element during the operation of the clamping device with the pre-calibrated clamping voltage range after each clamping is completed. If the voltage value detected by the Hall linear element falls within the pre-calibrated clamping voltage range, it indicates that the clamping at the corresponding clamping position is normal; if the voltage value detected by the Hall linear element does not fall within the pre-calibrated clamping voltage range, it indicates that the clamping at the corresponding clamping position is abnormal. Therefore, the clamping device provided in this embodiment provides a structural foundation for clamping monitoring. Furthermore, by placing the Hall linear element in the middle of the movement trajectory of the magnet of each ligation clip to be delivered from the first position to the second position on the clamping base plate, accurate calibration of the clamping voltage range is facilitated. By electrically connecting all Hall linear elements to the first communication interface, the handle can easily acquire and process the detection data of all Hall linear elements.

[0028] The clamp applicator and clamp delivery monitoring method provided by the present invention can monitor whether the clamp delivery work is normal after each clamp delivery is completed and before the next clamp delivery, that is, monitor whether there is a situation in the clamping chamber where the clamp to be delivered only moves to the top of the first elastic clamp on its far side but cannot cross the first elastic clamp on its far side.

[0042] 2: Handle. Detailed Implementation

[0043] It should be noted that in this article, "near" refers to the side closer to the operator, and "far" refers to the side closer to the patient. The directional terms "upper," "lower," "front," "back," "left," and "right" used in this article are... Figure 2 and Figure 5 The orientation is taken as a reference, where the direction from near to far is also the direction from back to front.

[0044] Example 1

[0045] To solve the above-mentioned technical problems, based on the structure of the clamping device 1 described in the background art, this embodiment provides a clamping device 1, such as... Figures 5 to 8As shown, the device includes a clamping chamber 12, multiple ligation clips 11 housed within the clamping chamber 12, and a first communication interface 14 for communication connection with a handle 2. The multiple ligation clips 11 include a ligation clip to be inserted at the farthest end of the clamping chamber 12 and ligation clips to be delivered arranged and stored near the ligation clip to be inserted. The support posts of the ligation clip to be inserted (including a first support post 111 and a second support post 112) are located far from the farthest first elastic locking position 122. The support posts of the ligation clips to be delivered are all located between two adjacent first elastic locking positions 122. One ligation clip to be delivered is accommodated between the first elastic clamping positions 122. When the ligation clip to be delivered is not acted upon by the push clamp 13, each ligation clip to be delivered can move between a first position and a second position. The first position is where the support column of the ligation clip to be delivered abuts against the far end of its adjacent first elastic clamping position 122 (preventing the ligation clip to be delivered from moving further forward). The second position is where the support column of the ligation clip to be delivered abuts against the proximal end of its adjacent far first elastic clamping position 122 (preventing the ligation clip to be delivered from moving further away). Each ligation clip 11 is equipped with a magnet 113. When the ligation clip to be delivered is not acted upon by the push clamp 13, the magnet 113 of each ligation clip to be delivered can move from the first position to the second position. A Hall linear element 121 is provided on the bottom plate of the clamp corresponding to the movement trajectory of the magnet 113 of each ligation clip from the first position to the second position. All Hall linear elements 121 are electrically connected to the first communication interface 14.

[0046] The Hall linear element 121 is a magnetic sensor with an analog signal output whose output voltage changes linearly with the input magnetic flux density. The voltage output of the Hall linear element 121 accurately tracks changes in magnetic flux density.

[0047] The clamping device 1 configured as described above, by pre-calibrating the detection voltage range of the Hall linear element 121 during the normal clamping process of the magnet 113 of the clamp to be delivered moving from the first position to the second position, can compare the pre-calibrated clamping voltage range with the voltage value detected by each Hall linear element 121 during the operation of the clamping device 1 after each clamping is completed. If the voltage value detected by the Hall linear element 121 falls within the pre-calibrated clamping voltage range, it indicates that the clamping at the clamping position corresponding to the Hall linear element 121 is normal. If the voltage value detected by the Hall linear element 121 does not fall within the pre-calibrated clamping voltage range, it indicates that the clamping at the clamping position corresponding to the Hall linear element 121 is abnormal. Therefore, the clamping device 1 provided in this embodiment provides a structural basis for realizing clamp delivery monitoring. Furthermore, by setting Hall linear elements 121 in the middle of the movement trajectory of the magnet 113 corresponding to each clamp to be delivered from the first position to the second position on the clamping bottom plate, it is convenient to accurately calibrate the clamp delivery voltage range. By electrically connecting all Hall linear elements 121 to the first communication interface 14, it is convenient for the handle 2 to obtain the detection data of all Hall linear elements 121 for processing and analysis.

[0048] Preferably, the Hall linear element 121 is a surface-mount Hall linear element 121. Using a surface-mount Hall linear element 121 facilitates its installation and arrangement on the clamping chamber bottom plate.

[0049] Furthermore, in this embodiment, the first elastic locking positions 122 are arranged sequentially from near to far and are all located on the left side of the clamping chamber bottom plate, while the Hall linear elements 121 are arranged sequentially from near to far and are all located on the right side of the clamping chamber bottom plate.

[0050] More preferably, in this embodiment, each ligation clip 11 is equipped with a magnet 113 at its tail, and a Hall linear element 121 is disposed at the distal end of the first elastic locking position 122.

[0051] Example 2

[0052] This embodiment provides a clamping device, which includes a handle 2 and a clamping device 1 as described in Embodiment 1, which is selectively connected to the handle 2.

[0053] The clamping device 1 further includes a memory for storing information on the number of clamps in the clamping chamber 12, the arrangement order of the Hall linear elements 121 in the clamping device 1, and the pre-calibrated clamping voltage range of the Hall linear elements 121. The handle 2 includes a second communication interface for connecting to a first communication interface 14; and a controller electrically connected to the second communication interface for updating the number of clamps stored in the memory after each clamping operation and before the next clamping operation. Based on the updated number of clamps and the arrangement order of the Hall linear elements 121 in the memory, the controller determines the Hall linear elements 121 to be judged in the clamping device 1. Based on the pre-calibrated clamping voltage range and the detection voltage value of the Hall linear elements 121 to be judged, the controller determines whether the clamping operation is normal.

[0054] The initial clamp quantity information stored in the memory is the clamp quantity information written into the memory when the clamping device 1 leaves the factory; subsequently, during the operation of the clamp applicator, after each clamp feeding or firing, the controller updates the clamp quantity information stored in the memory, that is, after each clamp feeding or firing, the controller decrements the clamp quantity stored in the memory by one.

[0055] The clamp applicator configured as described above can monitor whether the clamping operation is normal after each clamping operation and before the next clamping operation. Specifically, it can monitor whether there is a situation in the clamping chamber 12 where the clamp to be delivered only moves above the first elastic locking position 122 on its far side but cannot pass over the first elastic locking position 122 on its far side. Furthermore, when an abnormal clamping operation is detected, it can provide guidance for compensation for the poor clamping operation and can prevent the clamping operation from continuing the next clamping operation while the clamping clamp 11 is stuck in the clamping chamber 12, which would damage the drive structure of the handle 2.

[0056] Preferably, the controller is used to select, starting from the farthest Hall linear element 121 in the clamping compartment 12, one less Hall linear element 121 than the number of clamps as the Hall linear element 121 to be judged, according to the number of clamps updated in the memory.

[0057] Preferably, the controller is used to determine, based on a pre-calibrated clamping voltage range and the detection voltage value of the Hall linear element 121 to be judged, whether there is a detection voltage value of the Hall linear element 121 to be judged that does not fall within the pre-calibrated clamping voltage range. If such a value exists, the clamping operation is abnormal; if not, the clamping operation is normal. If there is a detection voltage value of the Hall linear element 121 to be judged that does not fall within the pre-calibrated clamping voltage range, it indicates that a clamp to be delivered has only moved above its far adjacent first elastic clamp 122 but cannot pass over its far adjacent first elastic clamp 122, indicating an abnormal clamping operation.

[0058] More preferably, the controller is used to determine the ligation clip 11 with abnormal clamping based on the detection voltage value of the Hall linear element 121 to be judged that does not fall within the pre-calibrated clamping voltage range and the arrangement order information of the Hall linear element 121.

[0059] Preferably, before the first clamp feeding, the controller determines the target number of Hall linear elements 121 whose detected voltage values ​​fall within the pre-calibrated clamp feeding voltage range, based on a pre-calibrated clamp feeding voltage range and the detected voltage values ​​of all Hall linear elements 121. If the target number plus one matches the number of clamps stored in the memory, the number of clamps stored in the memory is correct. If the target number plus one does not match the number of clamps stored in the memory, the number of clamps stored in the memory is incorrect, and the number of clamps stored in the memory is corrected based on the value of the target number plus one. In this way, the verification of the number of clamps pre-stored in the memory is achieved.

[0060] Preferably, the handle 2 further includes: a prompting unit for outputting an alarm signal; the controller is also used to instruct the prompting unit to output an alarm signal when the clamping operation is abnormal. This enables an alarm to be triggered when the clamping operation is abnormal, allowing the user to be notified and avoid performing the next clamping operation. The prompting unit can be a vibrator, speaker, indicator light, display screen, etc.

[0061] It should be noted that the controller can update the number of clips stored in the memory at any time after each clip feeding is completed and before the next clip feeding (including when clip feeding is completed, when firing is completed, and when resetting is completed).

[0062] More preferably, in this embodiment, the controller updates the number of clips stored in the memory each time clip feeding is completed. Based on the updated number of clips in the memory and the arrangement order of the Hall linear elements 121, the controller determines the Hall linear elements 121 to be judged in the clipping device 1. Based on the pre-calibrated clip feeding voltage range and the detection voltage value of the Hall linear elements 121 to be judged, the controller determines whether the clip feeding operation is normal. In this way, guidance can be provided for compensating for clip feeding defects.

Based on the pre-calibrated clamping voltage range and the detection voltage value of the Hall linear elements to be judged, determine whether the clamping operation is normal.

[0067] Preferably, determining the Hall linear element to be judged in the clamping device based on the number of clamps updated in the memory and the arrangement order information of the Hall linear elements includes: selecting one less Hall linear element than the number of clamps as the Hall linear element to be judged, starting from the farthest Hall linear element in the clamping compartment and proceeding from far to near, based on the number of clamps updated in the memory.

[0068] Preferably, determining whether the clamping operation is normal based on the pre-calibrated clamping voltage range and the detection voltage value of the Hall linear element to be judged includes: determining whether there is a detection voltage value of the Hall linear element to be judged that does not fall within the pre-calibrated clamping voltage range based on the pre-calibrated clamping voltage range and the detection voltage value of the Hall linear element to be judged; if so, the clamping operation is abnormal; if not, the clamping operation is normal.

[0069] Preferably, before S1, the method further includes: S0, before the first clamping, determining the target number of Hall linear elements whose detection voltage values ​​fall within the pre-calibrated clamping voltage range based on the pre-calibrated clamping voltage range and the detection voltage values ​​of all Hall linear elements; if the target number plus one is consistent with the number of clamps stored in the memory, then the number of clamps stored in the memory is correct; if the target number plus one is inconsistent with the number of clamps stored in the memory, then the number of clamps stored in the memory is incorrect, and the number of clamps stored in the memory is corrected based on the value after the target number plus one.

[0070] More preferably, the number of clips stored in the memory is updated each time the clip feeding is completed. Based on the updated number of clips in the memory and the arrangement order of the Hall linear elements, the Hall linear elements to be judged in the clipping device are determined. Based on the pre-calibrated clip feeding voltage range and the detection voltage value of the Hall linear elements to be judged, it is determined whether the clip feeding operation is normal.

A clamp applicator, characterized in that, Includes a handle (2) and a clamping device as described in any one of claims 3 to 5 connected to the handle (2); The clamping device also includes: a memory for storing information on the number of clamps in the clamping compartment (12), as well as information on the arrangement order of the Hall linear elements (121) in the clamping device and the pre-calibrated clamping voltage range of the Hall linear elements (121); The handle (2) includes: a second communication interface for connecting to the first communication interface (14); and a controller electrically connected to the second communication interface for updating the number of clamps stored in the memory after each clamping operation and before the next clamping operation, determining the Hall linear element (121) to be judged in the clamping device based on the updated number of clamps in the memory and the arrangement order information of the Hall linear element (121), and determining whether the clamping operation is normal based on the pre-calibrated clamping voltage range and the detection voltage value of the Hall linear element (121) to be judged.

7. The clamp applicator according to claim 6, characterized in that, The controller is used to select, starting from the farthest Hall linear element (121) in the clamping compartment (12) and proceeding from far to near, Hall linear elements (121) that are one less than the number of clamps as Hall linear elements (121) to be judged, based on the number of clamps updated in the memory.

8. The clamp applicator according to claim 6, characterized in that, The controller is used to determine whether there is a detection voltage value of the Hall linear element (121) that does not fall within the pre-calibrated clamping voltage range, based on the pre-calibrated clamping voltage range and the detection voltage value of the Hall linear element (121) to be judged. If it exists, the clamping operation is abnormal; if it does not exist, the clamping operation is normal.

9. The clamp applicator according to claim 6, characterized in that, The controller is also used to determine the target number of Hall linear elements (121) whose detection voltage values ​​fall within the pre-calibrated clamping voltage range before the first clamping operation, based on the pre-calibrated clamping voltage range and the detection voltage values ​​of all Hall linear elements (121). If the target number plus one is consistent with the number of clamps stored in the memory, then the number of clamps stored in the memory is correct. If the target number plus one is inconsistent with the number of clamps stored in the memory, then the number of clamps stored in the memory is incorrect, and the number of clamps stored in the memory is corrected based on the value after the target number plus one.

10. The clamp applicator according to claim 6, characterized in that, The handle (2) also includes: a prompting unit for outputting an alarm signal; the controller is also used to instruct the prompting unit to output an alarm signal when the clamping operation is abnormal.
