Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a stapler cutting blade detection device. Background Technology

[0002] A stapler is a surgical instrument used to quickly connect human tissues. It is mainly used to replace traditional manual suturing and improve surgical efficiency and safety. The sharpness of the stapler's cutting blade is one of the important guarantees for the smooth progress of the operation. If the cutting blade becomes dull, it will be difficult for the doctor to cut or remove the patient's tissue during the operation, and it will also cause great pain to the patient. Therefore, it is necessary to test the sharpness of the stapler's cutting blade to ensure that the cutting blade of the stapler used meets the surgical requirements.

[0003] Currently, most methods for testing the sharpness of stapler cutters are manual. When testing the sharpness of the same cutter at multiple points, the tester needs to manually install and clamp the suture and adjust the test position of the stapler cutter multiple times. This operation is cumbersome and inconvenient, and the accuracy of the test data is also unstable. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a stapler cutter detection device that can replace manual detection methods and simultaneously achieve accurate, convenient, and reliable detection of the sharpness performance of the stapler cutter.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This invention provides a stapler cutter detection device, comprising a vertical drive assembly, a horizontal drive assembly, a cutter testing assembly mounted on the vertical drive assembly, and a suture clamp mounted on the horizontal drive assembly. The cutter testing assembly includes a connector unit for mounting the stapler cutter and a pressure sensor mounted on the connector unit, the connector unit being mounted on the lifting end of the vertical drive assembly. The suture clamp includes a counterweight for tightening the suture, multiple threading posts, and a clamping actuator cooperating with each threading post. The threading posts are for the suture to pass through, and the clamping actuators are for clamping the suture located within the threading posts. The horizontal drive assembly drives the suture clamp to move so that the threading posts correspond to the connector unit, and the vertical drive assembly drives the stapler cutter on the connector unit to cut the suture on the suture clamp. The pressure sensor measures the cutting force borne by the stapler cutter to detect its sharpness.

[0007] Furthermore, the suture clamp also includes a mounting frame, which has multiple receiving cavities for accommodating the clamping actuator, and the clamping actuator is assembled in a corresponding receiving cavity; the receiving cavity has a mounting hole for mounting the threading post on the wall facing the connector unit, and the threading post is assembled in a corresponding mounting hole; the telescopic end of the clamping actuator is equipped with a clamping member, the clamping member has a pressure head, and the threading post has a guide groove that cooperates with the pressure head and a threading hole that communicates with the guide groove; during testing, the pressure head of the clamping member can be movably extended into the guide groove to clamp the suture that enters the guide groove through the threading hole.

[0008] Furthermore, the mounting bracket is equipped with a pulley for supporting the suture thread; during testing, the suture thread is wound around the pulley, and the end of the suture thread away from the threading post is attached to the counterweight, so that the counterweight is suspended in the air.

[0009] Furthermore, the clamping actuator is a cylinder; the counterweight is a weight.

[0010] Furthermore, the lateral drive component is an electric slide table.

[0011] Furthermore, the cutting blade testing assembly also includes a connecting frame, and the connecting head unit includes a rotary connecting head and a translational connecting head; the rotary connecting head is assembled inside the connecting frame for mounting an annular cutting blade and driving the annular cutting blade on the rotary connecting head to rotate at a fixed point; the translational connecting head is assembled on the outer wall of the connecting frame for mounting a linear cutting blade and driving the linear cutting blade on the translational connecting head to translate at a fixed point; the connecting frame is assembled to the lifting end of the vertical drive assembly.

[0012] Furthermore, the rotary connector includes a rotary driver capable of rotating at a fixed point; the translational connector includes a translational driver capable of translating at a fixed point.

[0013] Furthermore, the vertical drive assembly is a lead screw drive assembly, used to drive the connecting frame to rise and fall, so that the stapler cutter on the connecting head unit moves away from or closer to the suture on the suture clamp.

[0014] The technical solution provided by this utility model has the following beneficial effects:

[0015] By passing the suture through multiple threading posts and cooperating with corresponding clamping drivers, the suture located in each threading post is clamped separately. This allows the suture to be divided into multiple test segments at different test time periods, and the counterweight always keeps the test segments of other sutures that have not been cut taut.

[0016] During testing, the suture clamp is moved by the lateral drive assembly so that each threading post or each detection segment is aligned with the stapler cutter on the connector unit. Then, the stapler cutter on the connector unit is driven by the vertical drive assembly to cut the suture on the suture clamp. The cutting force borne by the stapler cutter is measured by the pressure sensor to detect its sharpness. Therefore, only one clamping of the suture and stapler cutter is required, and multi-point testing can be completed under the set test program. This avoids the need for the tester to manually clamp the suture multiple times and adjust the cutting position of the stapler cutter blade, thus preventing unstable test data. It also allows for accurate and reliable test results to be obtained in a shorter time. Therefore, this invention can achieve accurate, convenient, and reliable testing of the sharpness performance of the stapler cutter. Attached Figure Description

[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] Reference Figures 1 to 3 This embodiment provides a stapler cutter detection device (hereinafter referred to as the detection device) for detecting the sharpness performance of the stapler cutter, thereby ensuring the smooth progress of subsequent surgeries. In this embodiment, the stapler cutter is a ring cutter 6 or a linear cutter 7.

[0023] like Figure 1 As shown, the detection device in this embodiment includes a vertical drive assembly 1, a horizontal drive assembly 2, a cutting blade test assembly 3 assembled in the vertical drive assembly 1, and a suture clamp 4 assembled in the horizontal drive assembly 2.

[0024] The cutting blade test assembly 3 includes a connecting frame 34, a connector unit for mounting the stapler cutting blade, and a pressure sensor 33 mounted on the connector unit. The connector unit is mounted on the lifting end of the vertical drive assembly 1. Specifically, the connector unit includes a rotating connector 31 and a translating connector 32. The rotating connector 31 is mounted inside the connecting frame 34, and the translating connector 32 is mounted on the outer wall of the connecting frame 34. The connecting frame 34 is mounted on the lifting end of the vertical drive assembly 1.

[0025] More specifically, the rotary connector 31 includes a rotary driver capable of fixed-point rotation for mounting the annular cutter 6, driving the annular cutter 6 on the rotary driver to rotate at a fixed point to adjust different test positions of the annular cutter 6. Naturally, this rotary driver is a motor assembly with rotating gears, which is common in the prior art.

[0026] The translation connector 32 includes a translation driver capable of fixed-point translation for mounting the wire cutter 7, thereby driving the wire cutter 7 on the translation driver to perform fixed-point translation to adjust the different test positions of the wire cutter 7. Of course, this translation driver is a motor assembly with a lead screw structure, which is common in the prior art.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the suture clamp 4 includes a mounting frame 44, a counterweight 41 for tightening the suture 5, multiple threading posts 42, and a clamping driver 43 that is matched with each threading post 42. That is, the threading post 42 and the clamping driver 43 are configured in a one-to-one correspondence, and the specific clamping driver 43 is a cylinder, and the counterweight 41 is a 100g weight.

[0028] The mounting bracket 44 is provided with multiple receiving cavities 441 for accommodating each clamping actuator 43 and pulleys 46 for supporting the suture 5. Each clamping actuator 43 is assembled in its corresponding receiving cavity 441. Each receiving cavity 441 has a mounting hole 442 for mounting the threading post 42 facing the wall of the connector unit. Each threading post 42 is assembled in its corresponding mounting hole 442. The threading post 42 is used for the suture 5 to pass through. The clamping actuator 43 is used to clamp the suture 5 located in the threading post 42.

[0029] In this specific embodiment, the specific lateral drive component 2 is an electric slide table belonging to the prior art, which drives the suture clamp 4 to move left and right so that each threading post 42 is respectively aligned with the connector unit. The specific vertical drive component 1 is a screw drive component belonging to the prior art, which is used to drive the connector frame 34 to rise and fall so that the stapler cutter on the connector unit moves away from or closer to the suture 5 on the suture clamp 4. The cutting force borne by the stapler cutter is measured by the pressure sensor 33 to detect its sharpness.

[0030] Also, such as Figure 2 and Figure 3 As shown, the telescopic end of the clamping driver 43 is equipped with a clamping member 45. The clamping member 45 has a cylindrical clamping head. Each threading post 42 has a guide groove 422 that matches the clamping head and two threading holes 421 that are arranged opposite to each other and communicate with the guide groove 422. The pulley 46 is mounted on the left end of the mounting bracket 44 (i.e., the end of the mounting bracket 44). The sewing thread 5 is wound around the pulley 46, and a counterweight 41 is attached to the end of the sewing thread 5 away from the end of the threading post 42.

[0031] When clamping the suture 5, first pass the suture 5 through the threading holes 421 of each threading post 42 from left to right. Then, the rightmost clamping driver 43 drives the corresponding clamping head to extend into the corresponding guide groove 422 to press the suture 5 against the inner wall of the guide groove 422. This can clamp the starting end of the suture 5. Then, attach a counterweight 41 to the left end of the suture 5. At this time, the suture 5 passes around the pulley 46 and is in a hanging state to keep the suture 5 taut. This can ensure that the suture 5 is not affected by friction during the test, thereby ensuring the accuracy of the experimental data. Afterwards, other clamping drivers 43 drive the corresponding clamping heads to extend into the corresponding guide grooves 422 to clamp the suture 5 that enters the guide groove 422 through the threading holes 421. Therefore, the suture 5 can be divided into multiple detection segments 51 (such as 4 detection segments 51) at different test time periods.

[0032] During testing, the annular cutter 6 is first assembled onto the quick-connect interface of the rotary connector 31, and then the mounting bracket 44 is moved to the leftmost end by the transverse drive component 2. At this time, the threading post 42 at the rightmost end of the suture clamp 4 is aligned with the blade of the annular cutter 6.

[0033] The vertical drive assembly 1 drives the annular cutter 6 to move downward at a speed of 10 mm / min until it cuts the suture 5. When the suture 5 is cut, the telescopic end of the rightmost clamping driver 43 retracts to release the suture 5. At the same time, the adjacent left clamping driver 43 begins to clamp the end of the suture 5. Then, the vertical drive assembly 1 drives the cutter test assembly 3 to move upward and reset. Simultaneously, the rotary driver of the rotary connector 31 drives the annular cutter 6 to rotate a certain angle to adjust the cutting position of the annular cutter 6 to the next preset test position.

[0034] The suture clamp 4 is moved to the right by the lateral drive assembly 2 so that the blade of the annular cutter 6 corresponds to the next left-hand threading post 42. This process is repeated until the leftmost detection segment 51 of the suture 5 is cut. In this way, multiple (e.g., a total of 4 cuts) of the suture 5 can be completed with only one clamping of the suture 5 and the stapler cutter. The cutting force value borne by the stapler cutter is recorded by the pressure sensor 33.

[0035] The detection device in this specific embodiment also includes a central control system, which coordinates the operation of the vertical drive assembly 1, the horizontal drive assembly 2, the rotary connector 31, the pressure sensor 33, and each clamping actuator 43 to ensure orderly cooperation among them. The system also transmits the force value detection data of the pressure sensor 33 to the central control system for data processing, so as to automatically convert the sharpness test results of the stapler cutter into a linear graph of cutting force and corresponding data analysis, and finally display it directly on the display terminal 8.

[0036] By passing the suture 5 through multiple threading posts 42 and cooperating with the corresponding clamping actuators 43, the ends of the suture 5 located in each threading post 42 are clamped respectively. In this way, the suture 5 can be divided into multiple detection segments 51 at different test time periods, and the counterweight 41 always pulls the detection segments 51 of other uncut suture 5.

[0037] During testing, the suture clamp 4 is moved by the lateral drive assembly 2 so that each threading post 42 or each detection segment 51 is aligned with the stapler cutter on the connector unit. Then, the stapler cutter on the connector unit is driven by the vertical drive assembly 1 to cut the suture 5 on the suture clamp 4. The cutting force borne by the stapler cutter is measured by the pressure sensor 33 to test its sharpness. Therefore, only one clamping of the suture 5 and the stapler cutter is required, and multi-point testing is completed under the set test program. This avoids the need for the tester to manually clamp the suture 5 multiple times and adjust the cutting position of the stapler cutter blade, thus preventing unstable test data. It also allows for accurate and reliable test results to be obtained in a shorter time. Therefore, this utility model can achieve accurate, convenient and reliable testing of the sharpness performance of the stapler cutter.

[0038] Of course, in other embodiments, when the linear cutter 7 is assembled into the quick-connect interface of the translation connector 32, the method for testing the sharpness performance of its stapler cutter is similar to that of the annular cutter 6, and therefore will not be described in detail.

[0039] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
