Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a propulsion detection system and an anastomosis device. Background Technology

[0002] In recent years, the intelligentization of surgical instruments has driven the gradual application of electric staplers in clinical practice. However, most current products lack the ability to detect the advance status of the stapler blade, making it difficult for medical staff to accurately judge the problem in the first instance during the cutting process. They can only rely on experience to make judgments, which not only increases the difficulty of operation but also may lead to the risk of misoperation, restricting the improvement of surgical accuracy and safety, and also exposing the urgency of functional improvement in the process of intelligentization of instruments. Utility Model Content

[0003] This application aims to provide a propulsion detection system and anastomosis device capable of detecting the propulsion status of the blade.

[0004] The propulsion detection system according to a first aspect embodiment of this application includes: The sensing element is disposed on the propulsion assembly inside the anastomosis gun body. The propulsion assembly is used to move along the blade forward direction under the drive of the drive mechanism to push the blade forward. Multiple sensing sensors are sequentially arranged on the path of the moving sensing element, and each sensing sensor is used to sense the position of the sensing element; The controller is electrically connected to each of the aforementioned sensing sensors.

[0005] The anastomosis device according to a second aspect embodiment of this application includes the propulsion detection system as described in the first aspect embodiment.

[0006] The propulsion detection system and anastomosis device of this application embodiment can sense a certain area of ​​sensing element through each sensing sensor. Multiple sensing sensors are arranged on the path of the moving sensing element, and the detection ranges of the multiple sensing elements do not overlap. Thus, when the sensing element moves, the specific position reached by the sensing element can be sensed sequentially. At the same time, since the sensing element is set on the propulsion component that moves synchronously with the blade, the moving position of the blade can be determined by detecting the moving position of the sensing element, thereby completing the detection of the blade propulsion state.

[0013] In the description of this application, it should be noted that, unless otherwise explicitly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0014] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this application, not all embodiments.

[0015] See Figures 1 to 4 As shown, one embodiment of this application provides a propulsion detection system, which includes: The sensor 110 is disposed on the propulsion assembly 230 inside the stapler gun body 210. The propulsion assembly 230 is used to move along the forward direction of the blade 220 under the drive of the drive mechanism 240, so as to push the blade 220 forward. Multiple sensing sensors 120 are sequentially arranged on the path of the forward movement of the sensing element 110, and each sensing sensor 120 is used to sense the position of the sensing element 110. The controller 130 is electrically connected to a plurality of sensing sensors 120.

[0016] In this embodiment, each sensing sensor 120 can sense the sensing element 110 within a certain area. Multiple sensing sensors 120 are arranged on the path of the moving sensing element 110, and the detection ranges of the multiple sensing elements 110 do not overlap. Thus, when the sensing element 110 moves, the specific position reached by the sensing element 110 can be sensed sequentially. At the same time, since the sensing element 110 is set on the propulsion assembly 230 that moves synchronously with the blade 220, the moving position of the blade 220 can be determined by detecting the moving position of the sensing element 110, thereby completing the detection of the propulsion state of the blade 220.

[0017] The aforementioned stapler includes a gun body 210, a staple cartridge, and a battery. The staple cartridge is detachably connected to the gun body 210 to facilitate replacement and maintenance of the staple cartridge. The battery provides power for the operation of the stapler.

[0018] The staples in the staple cartridge can be advanced by the blade 220 located inside the gun body 210. The gun body 210 is equipped with a drive mechanism 240 that pushes the propulsion assembly 230 forward. When the propulsion assembly 230 moves forward, it further drives the blade 220 forward, thereby enabling the stapler to begin the stapler's operation.

[0019] The core controller 130 of the aforementioned controller 130 can be a DSP, ARM, microcontroller, etc. The specific type can be flexibly selected according to the actual data processing requirements. For example, an STM32 series processor can be selected.

[0020] Each of the aforementioned sensors 120 can sense the sensing element 110 within a certain area. By arranging multiple sensors 120 along the path of the moving sensing element 110, and ensuring that the detection ranges of the multiple sensing elements 110 do not overlap, it is possible to sequentially sense whether the sensing element 110 has reached a specific position as it moves. Specifically, refer to... Figure 4When the blade 220 begins to move, the leftmost sensor 120 is the first to detect the sensor 110. Then, as the blade 220 continues to move, multiple sensors 120 from left to right will detect the sensor 110 in sequence. When the rightmost sensor 120 detects the sensor 110, it can be determined that the blade 220 has been pushed forward.

[0021] In some embodiments, the sensing sensor 120 is an optical coupler sensor, which has a passage channel for the sensing element 110 to pass through. When the sensing element 110 passes through the corresponding optical coupler sensor, it blocks the optical communication of the optical coupler sensor.

[0022] The aforementioned optical coupler sensor can form a grating or an optical communication link. When the sensing element 110 moves to the area where the optical coupler sensor is located, it will block the grating or the optical communication link. By detecting whether the optical signal is blocked, the sensing element 110 can be detected.

[0023] In some embodiments, the sensing sensor 120 can be an infrared probe. When the sensing element 110 moves to the area directly opposite the infrared probe, it can effectively reflect infrared light to determine the sensing position.

[0024] In some implementations, the sensing sensor 120 is provided with 6 to 12 sensors.

[0025] In this embodiment, the number of sensing sensors 120 is set to 6 to 12, which can meet the operational accuracy requirements in most cases.

[0026] In some implementations, the sensing sensor 120 is provided with eight sensors.

[0027] In this embodiment, the number of sensing sensors 120 is set to 8, which can meet the operational accuracy requirements in common scenarios.

[0028] In some implementations, reference Figure 1 , Figure 2 The advanced detection system also includes: The display unit 150, which is electrically connected to the controller 130, is located on the top of the anastomosis device's gun body 210.

[0029] In this embodiment, the advance detection system can detect the advance distance of the blade 220, thereby monitoring the advance status of the blade 220. Finally, the advance distance and advance status of the blade 220 can be displayed in real time through the display unit 150, so that the operator can keep track of the working status of the stapler in real time.

[0030] In some implementations, reference Figure 1 , Figure 3 The aforementioned propulsion detection system also includes: The operation unit 140 is electrically connected to the controller 130.

[0031] The aforementioned operation unit 140 can be understood as an activation button. The activation button is used to control the motor 241 to achieve forward and reverse rotation, so as to control the forward and backward movement of the propulsion component 230.

[0032] In some implementations, reference Figure 3 , Figure 4 The propulsion assembly 230 includes a rack for connecting the blade 220, and a sensor 110 is disposed on the rack.

[0033] In this embodiment, a rack structure is used to connect the blade 220, thereby enabling displacement control of the blade 220 by driving the rack structure to move. Furthermore, using a rack facilitates the setting of the positions of the multiple sensors 120 by mounting the sensing element 110 on the rack.

[0034] In some implementations, reference Figure 3 , Figure 4 Multiple sensors 120 are located above the rack, and the detection path formed by the multiple sensors 120 is parallel to the rack. The sensing element 110 is disposed on the upper surface of the rack.

[0035] In this embodiment, multiple sensing sensors 120 are arranged in the large space above the rack, so that the sensing element 110 can be set on the upper surface of the rack and the multiple sensing sensors 120 can be effectively triggered by the sensing element 110.

[0036] In some implementations, reference Figure 3 , Figure 4 The drive mechanism 240 includes a motor 241 and a gear 242. The motor 241 drives the gear 242 to rotate, thereby driving the rack to move along the forward direction of the blade 220.

[0037] In this embodiment, the drive method using the combination of motor 241 and gear 242 can directly and effectively drive the rack, thereby driving the blade 220. The electrical control logic is relatively simple and has high control precision, making it suitable for surgical use.

[0038] The aforementioned gear 242 meshes with the rack, and the motor 241 drives the gear 242 to rotate, thereby driving the rack to move along the forward direction of the blade 220, thus pushing the blade 220 forward.

[0039] This application also provides a stapler that includes the aforementioned advancement detection system. Because the stapler has the advancement detection system, it possesses all the beneficial effects of such a system.

[0040] The above are merely specific embodiments of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
