DETAILED DESCRIPTION

[0051] The exemplary embodiments disclosed in the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the specific embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope disclosed in the present application to those skilled in the art.

[0052] In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application, some technical features well known in the art are not described; that is, all features of the actual embodiments are not described here, and well-known functions and structures are not described in detail.

[0053] In order to thoroughly understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also have other implementation methods.

[0054] Embodiment 1

[0055] The present application provides a method for detecting the compatibility of a surgical instrument staple cartridge. The method can be implemented by a computer, which can be a computing device configured with a processor, which can be a general-purpose processor, a digital signal processor (DSP), a field programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0056] refer to Figure 1 , the method comprising:

[0057] Step 101: obtaining magnetic field information including at least two different magnetic fields measured by a magnetic field detector;

[0058] Step 102: Determine the specifications of the nail magazine to be installed according to the magnetic field information;

[0059] Step 103: Determine the compatibility of the nail magazine to be installed with the surgical instrument according to preset compatible nail magazine information.

[0060] Specifically, in step 101, the magnetic field is generated by a magnet, which may include a permanent magnet or an electromagnet. In this embodiment, at least two magnetic fields are provided, that is, there are at least two magnets. Taking two magnets as an example, the method for forming a permanent magnet may include: embedding two magnets of different materials on the same substrate, thereby generating different magnetic field strengths or directions to form two magnets; or in different regions of the same material, the magnetization is different, forming two magnetized regions with different magnetic field strengths or directions to form two magnets. For an electromagnet, different currents may be passed through as needed during use to generate different magnetic fields to form two magnets.

[0061] The magnetic field detector can detect magnetic field information of at least two magnetic fields when at least two magnetic fields are close to each other. The magnetic field information may include magnetic field strength, magnetic field direction, magnetic field lines, magnetic field strength distribution, etc.

[0062] It is understandable that a single magnetic field cannot record or transmit information, but a combination of two or more magnetic fields can record or transmit information. The more magnetic fields there are, the more information can be recorded or transmitted.

[0063] Information is recorded or transmitted through a combination of two or more magnetic fields, with a simple structure, reliable control and low cost.

[0064] In detail, in step 102, the magnetic field information can record or transmit information through different combinations of at least two magnetic field information, and the information may include the specifications of the nail magazine to be installed, the production date, the manufacturer, the production address, etc. For the method of this embodiment, it is necessary to determine the specifications of the nail magazine to be installed based on the magnetic field information.

[0065] It is understandable that the specification can be a specification in a broad sense, can be the most specific specification, for example, in addition to the size, it also includes the brand, material, production process, etc., or can be a general specification, for example, only including the type or size. Which one is used depends on the type of stapler.

[0066] It can be understood that in step 103, the preset compatible nail magazine information can be: a list of nail magazines compatible with the surgical instrument. Therefore, the specifications of the determined nail magazine to be installed are compared and retrieved with the preset compatible nail magazine information to determine the compatibility of the nail magazine to be installed with the surgical instrument. For example, if the specifications of the determined nail magazine to be installed appear in the preset compatible nail magazine information, it is considered to be compatible, otherwise, it is not compatible.

[0067] The surgical instrument staple magazine compatibility detection method, device, equipment, storage medium, surgical instrument and staple magazine of the embodiments of the present application determine the specifications of the staple magazine to be installed based on the magnetic field information of at least two different magnetic fields, and then determine the compatibility with the stapler, and are simple and quick.

[0068] In some other embodiments of the present application, the step of obtaining magnetic field information including at least two different magnetic fields measured by the magnetic field detector includes:

[0069] Acquiring detection data of the magnetic field detector;

[0070] Determining the strength distribution of the magnetic field according to the magnetic field strengths of different magnetic fields;

[0071] The magnetic field information is obtained according to the strength distribution.

[0072] It is understandable that the detection data of the magnetic field detector may include magnetic field intensity. Since there are at least two different magnetic fields, if there are two characteristics of magnetic field intensity, such as "strong" and "weak", then multiple combinations can be formed according to the distribution of magnetic field intensity of each magnetic field in space, and each combination corresponds to a specification of a nail magazine to be installed. For example, two magnetic fields can form four combinations of "strong and weak", "weak and strong", "strong and strong" and "weak and weak". For example, three magnetic fields can be expressed as "strong and strong", "strong and strong", "strong and weak and weak", "strong and weak and strong", "strong and weak and weak", "weak and strong", "weak and strong", "weak and strong", "weak and strong", "weak and strong", "weak and strong", "weak and weak", "weak and weak" 8 combinations. By analogy, the more magnetic fields there are, the more combinations there can be. In this embodiment, the number of magnetic fields can be 5, so that enough information can be transmitted and the cost is relatively controllable.

[0073] Furthermore, if there are three characteristics of magnetic field strength, such as "strong", "medium", and "weak", then there are two magnetic fields, and more combinations can be formed. For example, nine combinations of "strong-strong", "strong-medium", "strong-weak", "medium-strong", "medium-medium", "medium-weak", "weak-strong", "weak-medium", and "weak-weak" can be formed. By analogy, the more characteristics of magnetic field strength there are, the more combinations there are when the number of magnetic fields is constant. In this embodiment, there are two characteristics of magnetic field strength, so that detection is more reliable.

[0074] In some other embodiments of the present application, the step of obtaining magnetic field information including at least two different magnetic fields measured by the magnetic field detector includes:

[0075] Acquiring detection data of the magnetic field detector;

[0076] Determining polarity distribution of the magnetic field according to different magnetic field polarities;

[0077] The magnetic field information is acquired according to the polarity distribution.

[0078] Since there are at least two different magnetic fields, and there are two types of magnetic field polarities, namely "South" and "North", multiple combinations can be formed according to the spatial distribution of the magnetic field polarities of each magnetic field, and each combination corresponds to a specification of the nail magazine to be installed. For example, with two magnetic fields, four combinations of "North-South", "North-South", "South-South", and "North-North" can be formed. For example, with three magnetic fields, eight combinations of "South-South-South", "South-South-South", "South-South-South", "North-South-North", "North-South-South", "North-South-South", "North-North-South", and "North-North-North" can be formed. And so on, the more magnetic fields there are, the more combinations there can be. In this embodiment, the number of magnetic fields can be 5, so that enough information can be transmitted and the cost is relatively controllable.

[0079] In some other embodiments of the present application, the magnetic field detector is a Hall sensor, and the number of the Hall sensors corresponds to the number of the magnetic fields;

[0080] The obtaining of magnetic field information including at least two different magnetic fields measured by the magnetic field detector comprises:

[0081] Acquire output electrical signals of at least two of the Hall sensors; the output electrical signals include current or voltage;

[0082] The intensity or polarity of the magnetic field is determined according to the magnitude or direction of the output electrical signal of each Hall sensor to obtain the magnetic field information.

[0083] It is understandable that the Hall sensor can convert the measured magnetic field signal into an output electrical signal, such as a current or a voltage, for characterizing the strength of the magnetic field. Therefore, the magnetic field strength can be confirmed based on the output electrical signal of the Hall sensor.

[0084] Likewise, the direction of the output electrical signal, such as the direction of the current or voltage, can represent the direction of the magnetic field. Therefore, the direction of the magnetic field can be determined based on the output electrical signal of the Hall sensor.

[0085] The number of Hall sensors corresponds to the number of magnetic fields, that is, a Hall sensor is set for each magnetic field for detection, so that the detection is more accurate. In other embodiments of the present application, the obtaining of the magnetic field information includes:

[0086] According to the determined strength distribution of the magnetic field, converting the strength distribution into a digital label;

[0087] Alternatively, according to the determined polarity distribution of the magnetic field, the polarity distribution is converted into a digital label; the number of bits of the digital label is the same as the number of bits of the magnetic field.

[0088] Converting to digital labels is conducive to better control and execution. For example, converting the strong characteristics of magnetic field strength into digital "1" and converting the weak characteristics of magnetic field strength into digital "0". In the above combination of the strength and weakness of the magnetic field, there are two magnetic fields and two characteristics of magnetic field strength, which can be converted into four types: "10", "01", "11" and "00".

[0089] Similarly, the combination of the above magnetic field polarity distribution conditions can also be converted in this way. For example, "south" is converted to "1" and "north" is converted to "0".

[0090] Furthermore, the method further comprises:

[0091] After determining the compatibility of the to-be-installed nail magazine with the surgical instrument, a corresponding operating procedure is performed according to the identified specifications of the nail magazine and a preset surgical instrument operating procedure.

[0092] For example, different anastomosis speeds, anastomosis depths, anastomosis forces, etc. are selected according to the specifications of the staple cartridge, because staples of different sizes are suitable for different biological tissues and encounter different resistances, etc., and different anastomosis speeds, anastomosis depths, anastomosis forces, etc. need to be set. Of course, the compatibility detection step can also be used as a trigger for entering the regular program, such as adjusting the staple cartridge device of the end effector to the state of installing a new staple cartridge, or first checking whether the original staple cartridge device has any staples from the previous time, and if so, unloading operations can be performed.

[0094] The present application embodiment provides a surgical instrument staple cartridge compatibility detection device, referring to Figure 2 , the surgical instrument staple cartridge compatibility detection device comprises:

[0095] An acquisition module 31 is used to acquire magnetic field information including at least two different magnetic fields measured by a magnetic field detector;

[0096] A first determination module 32, configured to determine the specifications of the nail magazine to be installed according to the magnetic field information;

[0097] The second determination module 33 is used to determine the compatibility between the to-be-installed nail magazine and the surgical instrument according to preset compatible nail magazine information.

For example, two magnetic fields can form four combinations of "strong and weak", "weak and strong", "strong and strong" and "weak and weak". For example, three magnetic fields can be expressed as "strong and strong", "strong and strong", "strong and weak and weak", "strong and weak and strong", "strong and weak and weak", "weak and strong", "weak and strong", "weak and strong", "weak and strong", "weak and strong", "weak and strong", "weak and weak", "weak and weak" 8 combinations. By analogy, the more magnetic fields there are, the more combinations there can be. In this embodiment, the number of magnetic fields can be 5, so that enough information can be transmitted and the cost is relatively controllable.

[0104] Furthermore, if there are three characteristics of magnetic field strength, such as "strong", "medium", and "weak", then there are two magnetic fields, and more combinations can be formed. For example, nine combinations of "strong-strong", "strong-medium", "strong-weak", "medium-strong", "medium-medium", "medium-weak", "weak-strong", "weak-medium", and "weak-weak" can be formed. By analogy, the more characteristics of magnetic field strength there are, the more combinations there are when the number of magnetic fields is constant. In this embodiment, there are two characteristics of magnetic field strength, so that detection is more reliable.

[0106] Acquiring detection data of the magnetic field detector;

[0107] Determining polarity distribution of the magnetic field according to different magnetic field polarities;

[0108] The magnetic field information is acquired according to the polarity distribution.

And so on, the more magnetic fields there are, the more combinations there can be. In this embodiment, the number of magnetic fields can be 5, so that enough information can be transmitted and the cost is relatively controllable.

[0110] In some other embodiments of the present application, the magnetic field detector is a Hall sensor, and the number of the Hall sensors corresponds to the number of the magnetic fields;

[0111] The acquisition module 31 is also used for:
