[0001] This application relates to the field of medical devices, and in particular to a blade release structure and a blade. Background Technology
[0002] A scalpel is a specialized cutting tool consisting of a blade and a handle, used to cut human or animal tissues. It is an indispensable and important surgical tool in surgical procedures.
[0003] Post-operatively, surgical nurses need to separate the blade from the handle and then dispose of the blade as medical waste. Currently, surgical nurses typically separate the blade from the handle manually, which is inefficient and increases the risk of occupational exposure. Utility Model Content
[0004] This application primarily addresses the technical problems of low efficiency and potential occupational exposure associated with manual detachment after surgery in existing technologies. It provides a blade detachment structure for detaching a blade from the handle, characterized in that the blade detachment structure comprises…
[0005] The detached body has a first receiving cavity extending through it along a first direction. The first receiving cavity has an inlet and an outlet at its two ends along the first direction, respectively.
[0006] The first receiving cavity has a first surface and a second surface on its two sides along the second direction, respectively;
[0007] A blocking block is provided on the first surface of the first receiving cavity, and a specific infeed gap is provided between the blocking block and the second surface;
[0008] A first outlet is disposed within the detachment body, located at the bottom of the first receiving cavity along the second direction, communicating with the first receiving cavity, and penetrating the blocking block.
[0009] The blade release structure is inclined downwards from the inlet to the outlet.
[0010] In one possible implementation, the blocking blocks are provided on both sides of the first outlet.
[0011] In one embodiment, the blade disengagement structure further includes,
[0012] A contact block is disposed in the first receiving cavity along the first direction, and the contact block forms a contact surface disposed along the first direction, the contact surface being disposed toward the first surface.

[0014] In one embodiment, the blade disengagement structure further includes,
[0015] A mechanical connector, comprising a first connector and a second connector, wherein the first connector and the second connector are respectively disposed on both sides of the detached body along the second direction.
[0016] In one embodiment, the blade disengagement structure further includes,
[0017] A movable component is disposed on both sides of the detached body along a third direction, and the movable component protrudes from the surface of the detached body.
[0018] This application, in another aspect, provides a blade release device, characterized in that it includes the blade release structure described in Embodiment 1, and the blade release device further includes...
[0019] The main housing has a second receiving cavity. The blade release structure is disposed in the main housing. The blade outlet faces the second receiving cavity, and the blade inlet faces outward.
[0020] In one embodiment, the blade disengagement device further includes,
[0021] A connecting block is located within the second receiving cavity and is fixedly connected to the main housing. A third receiving cavity extends through the connecting block and communicates with the second receiving cavity. The blade release structure is located within the third receiving cavity and is detachably connected to the connecting block via a connecting assembly.
[0022] The connecting assembly includes a mechanical connector and a mechanical mating component. The mechanical connector and the mechanical mating component are detachably connected. The mechanical connector is disposed on the detachable body, and the mechanical mating component is disposed on the connecting block.
[0023] In one embodiment, the connecting block is provided with movable grooves on both sides along the arrangement direction of the third receiving cavity. The movable grooves are connected to the third receiving cavity. The movable grooves extend to both sides and penetrate the main housing. The movable component is located in the movable grooves, and part of the movable component is located outside the main housing. When the movable component moves in the movable grooves, the detachment body moves synchronously in the third receiving cavity.
[0024] The bottom of the connecting block is provided with a second clearance groove, which extends toward the main housing and penetrates the main housing. The second clearance groove is used to accommodate the mounting section of the handle. When the blade detachment structure is located in the third receiving cavity, the second clearance groove is connected to the first outlet.

[0027] Compared to existing technologies, in practical use, the blade of this application, along with the mounting section of the handle, is first inserted into the first receiving cavity through the inlet. Then, the handle is pressed down, causing the first end of the blade to abut against the second surface of the first receiving cavity, and the second end of the blade to abut against the first surface of the first receiving cavity, creating a gap between the blade and the mounting section of the handle. At this point, the blade remains within the first receiving cavity, while the mounting section of the handle partially enters the first outlet. Finally, the handle is pulled outwards, causing the second end of the blade to abut against the blocking block, completely separating the blade from the handle, thus achieving blade detachment. This blade detachment structure avoids hand contact with the blade when detaching it from the handle, and the blade remains within the detachment structure throughout the detachment process, thus preventing occupational exposure. Furthermore, detaching the blade using this blade detachment structure requires only two steps: pressing down the handle and pulling it out, making operation simple and highly efficient.
[0028] Therefore, this application has the characteristics of reasonable structure and convenient use. Attached Figure Description

[0062] Example 1:
[0063] Please refer to the attached document. Figure 1 To be continued Figure 8The illustration shows a specific embodiment of the blade detachment structure 10 of this application. The blade detachment structure 10 of this application is used to achieve mechanical separation of the blade 110 from the handle 120, thereby avoiding direct hand contact with the blade 110 and improving the detachment efficiency of the blade 110. In one embodiment, the knife of this application is a surgical scalpel 100, and the detachment point of the blade 110 is postoperative detachment. Besides being applicable to surgical scalpels 100, the blade detachment structure 10 of this application is also applicable to knives where the blade 110 and handle 120 are connected by a snap-fit structure.
[0064] Appendix Figure 1 This is a schematic diagram of one structure of the surgical scalpel 100 of this application. (Attached) Figure 2 This is a schematic diagram of one structure of the blade 110 of this application. Please refer to the attached diagram. Figure 1 and appendix Figure 2 As shown, the scalpel 100 of this application includes a blade 110 and a handle 120, which are connected by a snap-fit mechanism. The handle 120 includes a mounting section 121 and a holding section 122. The mounting section 121 is located at one end of the holding section 122 and is fixedly connected to it. The width of the mounting section 121 is smaller than the width of the holding section 122, and the mounting section 121 and the holding section 122 are connected by a transition joint, the width of which gradually increases from the mounting section 121 to the holding section 122. A protrusion is formed on the mounting section 121 facing the blade 110, and a groove is provided circumferentially around the protrusion. The mounting section 121 mounts the blade 110 through the protrusion, and a portion of the blade 110 is snapped into the groove.
[0065] In one embodiment, the mounting section 121 and the handheld section 122 are manufactured as a single unit.
[0066] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the blade 110 of this application includes a mounting area 111 and an abutment area 112. The mounting area 111 is the through hole penetrating the blade 110 and the area surrounding the through hole. When the blade 110 is mounted on the handle 120, the protrusion of the mounting section 121 is located within the mounting area 111. When the blade 110 is mounted on the mounting section 121, the mounting area 111 contacts the mounting section 121, and the abutment area 112 protrudes relative to the mounting section 121, but does not contact the mounting section 121. Therefore, when detaching the blade 110, the initial separation of the blade 110 from the handle 120 can be achieved by raising the region 112.
[0067] The blade 110 includes an upper surface 113 and a lower surface 114, which are located on the upper and lower sides of the blade 110, respectively.
[0068] The blade 110 includes a first end 115 and a second end 116, and the width of the first end 115 of the blade 110 is smaller than the width of the second end 116 of the blade 110. When the blade 110 is installed on the mounting section 121, the second end 116 of the blade 110 is spaced apart from the handheld section 122.
[0069] Please refer to the attached document. Figure 3 To be continued Figure 8 As shown, the first direction X of this application refers to the length direction of the blade detachment structure 10, that is, the direction from left to right or from right to left of the blade detachment structure 10. In this application, the inlet 211 of the first receiving cavity 210 is positioned to the right of the outlet 212 of the first receiving cavity 210, and the outlet 212 of the first receiving cavity 210 is positioned to the left of the inlet 211 of the first receiving cavity 210. The second direction Y of this application refers to the height direction of the blade detachment structure 10, that is, the direction from top to bottom or from bottom to top of the blade detachment structure 10. In this application, the first connector 611 is positioned higher than the second connector 612, and the second connector 612 is positioned lower than the first connector 611. The width direction of this application refers to the width direction of the blade detachment structure 10, that is, the direction from left to right or from right to left of the blade detachment structure 10.
[0070] Appendix Figure 3 This is a schematic diagram of one possible structure of the blade detachment structure 10 of this application. (Attached) Figure 4 This is a schematic diagram of another structure of the blade detachment structure 10 in this application. Please refer to the attached diagram. Figure 3 and appendix Figure 4 As shown, the blade release structure 10 of this application includes a release body 200, which is an elongated structure. A first receiving cavity 210 is provided within the release body 200 along a first direction X. When the blade 110 is separated from the handle 120, the blade 110 remains within the first receiving cavity 210. In this application, the first receiving cavity 210 extends through the release body 200; therefore, an inlet 21 and an outlet 212 are respectively provided at both ends of the first receiving cavity 210 along the first direction X. The width of the inlet 211 and outlet 212 in the third direction Z is greater than the width of the mounting section 121 of the blade 110 and handle 120, but less than the width of the hand-held section 122 of the handle 120.
[0071] In practical use, the blade detachment structure 10 is generally tilted. Specifically, the inlet 211 is located above the outlet 212 in the height direction, so that when the blade 110 is separated from the handle 120, the blade 110 automatically slides out of the first receiving cavity 210 from the outlet 212.
[0072] In one embodiment, the detached body 200 of this application is a cuboid.
[0073] In one embodiment, any cross-section of the first receiving cavity 210 of this application is rectangular.
[0074] Please refer to the attached document. Figure 3 and appendix Figure 4 As shown, the detachment body 200 of this application has a first outlet 400 along the first direction X. The first outlet 400 of this application is located at the bottom of the first receiving cavity 210 along the second direction Y. The first receiving cavity 210 communicates with the outside in the second direction Y through the first outlet 400.
[0075] In actual use, the mounting section 121 of the handle 120 is disengaged from the first receiving cavity 210 through the first outlet 400.
[0076] Please refer to the attached document. Figure 3 and appendix Figure 4 As shown, the blade disengagement structure 10 of this application also includes a blocking block 300. The blocking block 300 ensures that the blade 110 remains within the first receiving cavity 210 when it disengages from the handle 120. In this application, the blocking block 300 is disposed within the first receiving cavity 210, and furthermore, the blocking block 300 is disposed on one side of the inlet 211. The first outlet 400 of this application simultaneously passes through the blocking block 300. The blocking block 300 of this application will be described in the appendix. Figure 6 and appendix Figure 7 Further details are provided below.
[0077] In one embodiment, blocking blocks 300 are provided on both sides of the first outlet 400.
[0078] Please refer to the attached document. Figure 3 and appendix Figure 4 As shown, the detachment body 200 of this application is also provided with a first clearance groove 410. The first clearance groove 410 is located in the extension direction of the first outlet 400 along the first direction X. The first clearance groove 410 is located on the side of the first outlet 400 near the inlet 211. The width of the first clearance groove 410 along the third direction Z is greater than the width of the first outlet 400 along the third direction Z. Since the connection between the handle 120 mounting section 121 and the handheld section 122 is a transition connection, the width of the connection of the handle 120 mounting section 121 is greater than the normal width of the handle 120 mounting section 121. In order for the handle 120 mounting section 121 to be able to move out of the first outlet 400 normally when the blade 110 is detached from the handle 120, the width of the first outlet 400 in the third direction Z is specially increased, that is, the width of the first clearance groove 410.
[0079] In one embodiment, the width of the first clearance groove 410 in the third direction Z is gradually reduced from the inlet 211 side to the outlet 212 side.
[0080] Please refer to the attached document. Figure 3 and appendix Figure 4 As shown, the blade release structure 10 of this application also includes a contact block 500. The contact block 500 is disposed in the first receiving cavity 210 along the first direction X. The contact block 500 is provided to increase the contact area 510 with the blade 110 after the blade 110 is tilted, so as to avoid the blade 110 breaking due to uneven force after tilting. At the same time, in this application, the blocking block 300 can be omitted, and the blade 110 can be separated from the handle 120 by the friction between the contact block 500 and the blade 110 when the handle 120 is withdrawn. In this application, the contact block 500 will be attached to the appendix. Figure 6 and appendix Figure 7 Further details are provided below.
[0081] Please refer to the attached document. Figure 3 and appendix Figure 4 As shown, the blade release structure 10 of this application also includes a mechanical connector 610, which is part of the connecting assembly 600. The connecting assembly 600 is used to realize the detachable connection between the blade release structure 10 and the connecting block 820 in Embodiment 2. The mechanical connector 610 of this application will be further described in Embodiment 2.
[0082] In one embodiment, the mechanical connector 610 includes a first connector 611 and a second connector 612, which are respectively disposed on both sides of the detachment body 200 along the second direction Y. Further, the first connector 611 is disposed on the upper surface of the detachment body 200 along the second direction Y, and there is one first connector 611. Further, the second connector 612 is disposed on the lower surface of the detachment body 200 along the second direction Y, and there are two second connectors 612, which are respectively located on both sides of the first outlet 400.
[0083] In one embodiment, both the first connector 611 and the second connector 612 are elongated structures.
[0084] In one embodiment, the length of the first connector 611 in the first direction X is longer than the length of the second connector 612 in the first direction X, so as to avoid interference between the blade detachment structure 10 and the second clearance groove 840 in embodiment 2 after installation.
[0085] Please refer to the attached document. Figure 3 and appendix Figure 4 As shown, the blade detachment structure 10 of this application also includes a movable member 700. The movable member 700 is disposed on both sides of the detachment body 200 along the third direction Z, and the movable member 700 protrudes from the surface of the detachment body 200. The movable member 700 is fixedly connected to the detachment body 200.
[0086] In actual use, when the moving part 700 is pushed, it moves synchronously away from the main body 200.
[0087] In one embodiment, the movable component 700 is a long strip structure.
[0088] Appendix Figure 5 This is a front view of the blade detachment structure 10 of this application. Please refer to the attached document.

(Attached) Figure 6 With appendix Figure 7 This is to further supplement the description of the blocking block 300 and the contact block 500.
[0090] Please refer to the attached document. Figure 6 and appendix Figure 7 As shown, the first receiving cavity 210 of this application is provided with a first surface 213 and a second surface 214 on both sides along the second direction Y. The first surface 213 is the lower surface of the first receiving cavity 210 along the second direction Y, and the second surface 214 is the upper surface of the first receiving cavity 210 along the second direction Y.
[0091] In one embodiment, the first surface 213 of the first receiving cavity 210 is arranged parallel to the second surface 214 of the first receiving cavity 210.
[0092] Please refer to the attached document. Figure 6 and appendix Figure 7 As shown, the blocking block 300 in the blade release structure 10 of this application is located within the first receiving cavity 210, and the blocking block 300 is located on one side of the inlet 211. Furthermore, the blocking block 300 is located on the first surface 213 of the first receiving cavity 210. The blocking block 300 extends from the first surface 213 to the second surface 214, and there is an inlet gap 310 between the blocking block 300 and the second surface 214, that is, one side of the blocking block 300 is connected to the first surface 213, and the other side of the blocking block 300 is spaced apart from the second surface 214.
[0093] In one embodiment, the side of the blocking block 300 along the first direction X is flush with the inlet 211.
[0094] Please refer to the attached document. Figure 6 and appendix Figure 7 As shown, the contact block 500 in the blade release structure 10 of this application is disposed within the first receiving cavity 210 along the first direction X. The contact block 500 forms a contact surface 510 disposed along the first direction X. The contact surface 510 is the lower surface of the contact block 500 along the second direction Y, and the contact surface 510 is disposed facing the first surface 213. Furthermore, the height of the contact block 500 in the second direction Y is a first height 520, which gradually decreases from the side facing the inlet 211 to the side facing the outlet 212, thereby adapting to the tilted state of the blade 110. Furthermore, the contact block 500 is disposed away from the inlet 211.
[0095] Appendix Figure 8 This is a schematic diagram of a structure between the scalpel 100 and the blade separation structure 10 of this application. Please refer to the attached diagram. Figure 8 As shown, in specific use, the blade 110 of this application, together with the mounting section 121 of the handle 120, is first inserted into the first receiving cavity 210 through the inlet 211. Further, the blade 110, together with the mounting section 121 of the handle 120, enters the first receiving cavity 210 through the inlet gap 310. At this time, the hand-held section 122 of the handle 120 is located outside the first receiving cavity 210. Then, the handle 120 is pressed down, causing the first end 115 of the blade 110 to tilt upwards, and the upper surface 113 of the blade 110 to contact the contact surface 510 of the contact block 500. The second end 116 of the blade 110 abuts against the first surface 213, and a gap is simultaneously formed between the blade 110 and the mounting section 121 of the handle 120. At this time, the blade 110 is still located within the first receiving cavity 210, while the mounting section 121 of the handle 120 partially enters the first outlet 400 from the first receiving cavity 210. Finally, while pressing down on the handle 120, pull the handle 120 outward. The second end 116 of the blade 110 moves toward the blocking block 300, and the second end 116 of the blade 110 abuts against the blocking block 300. Under the action of the blocking block 300, the blade 110 is completely separated from the handle 120, thus forming the separation of the blade 110 from the handle 120.
[0096] The blade release structure 10 of this application prevents the blade 110 from being touched by both hands when it is detached from the handle 120, and the blade 110 remains within the blade release structure 10 throughout the detachment process, thus avoiding occupational exposure. Furthermore, detaching the blade 110 using the blade release structure 10 of this application requires only two steps: pressing down on the handle 120 and pulling it away, making the operation simple and the blade 110 detachment highly efficient.
[0097] Example 2:
[0098] Please refer to the attached document. Figure 9 To be continued Figure 11As shown, a specific embodiment of the blade 110 disengagement device of this application is presented. To further utilize the blade disengagement structure 10 effectively, it is necessary to further mount the blade disengagement structure 10 onto other devices. Besides mounting the blade disengagement structure 10 onto the housing of this application, it can also be mounted on a trolley for holding the scalpel 100.
[0099] Appendix Figure 9 This is a cross-sectional view of the blade 110 disengagement device of this application. Please refer to the attached diagram. Figure 9 As shown, the blade 110 disengagement device of this application includes the blade disengagement structure 10 in Embodiment 1. For the specific composition of the blade disengagement structure 10, please refer to the description in Embodiment 1. The blade disengagement structure 10 will not be described in further detail in this embodiment.
[0100] Please refer to the attached document. Figure 9 As shown, the image detachment device of this application also includes a main housing 800. The main housing 800 is configured to further house the blade detachment structure 10, and the detached blade 110 is also temporarily stored within the main housing 800. The main housing 800 has a second receiving cavity 810. The exit port 212 of the blade detachment structure 10 faces the second receiving cavity 810, and the inlet port 211 of the blade detachment structure 10 faces outward. That is, the inlet port 211 of the blade detachment structure 10 is located on the surface of the main housing 800 or protrudes from the surface of the main housing 800. In this application, the blade detachment structure 10 is inclined downward from the inlet port 211 to the exit port 212, that is, the inlet port 211 of the blade detachment structure 10 is higher than the exit port 212 in the height direction, thereby facilitating the automatic sliding of the blade 110 into the third receiving cavity after it detaches from the handle 120.
[0101] Please refer to the attached document. Figure 9 As shown, the blade 110 release device of this application also includes a connecting block 820. The connecting block 820 is located in the second receiving cavity 810 and is fixedly connected to the main housing 800. A third receiving cavity is provided through the connecting block 820 and communicates with the second receiving cavity 810. A blade release structure 10 is provided in the third receiving cavity to fix the blade release structure 10 in the main housing 800.
[0102] In another embodiment, besides being fixed within the housing 800, the blade release structure 10 of this application can also be elastically connected to the connecting block 820. Specifically, the blade release structure 10 and the connecting block 820 are connected via an elastic component and a limiting component, thereby achieving an elastic connection between the blade release structure 10 and the third receiving cavity within the connecting block 820. In practical use, the user first presses down on the blade release structure 10. The limiting component releases the restriction between the blade release structure 10 and the connecting block 820. The elastic component ejects the blade release structure 10 from the third receiving cavity, and the inlet 211 simultaneously moves out of the third receiving cavity. Furthermore, the blade release structure 10 is tilted downwards from the inlet 211 to the outlet 212, allowing the user to operate the scalpel to separate the blade from the handle. Furthermore, when the user presses down again to disengage the blade from the structure, the limiting component re-establishes the limiting between the blade disengagement structure and the connecting block 820, and the inlet 211 is hidden again in the third receiving cavity to prevent other debris from entering the housing 800 through the inlet 211.
[0103] Please refer to the attached document. Figure 9 As shown, the blade detachment structure 10 of this application is detachably connected to the connecting block 820 via the connecting component 600, so as to facilitate the separate cleaning and disinfection of the blade detachment structure 10 and the main housing 800. Because the main housing 800 is a semi-enclosed structure, if the blade detachment structure 10 and the main housing 800 are cleaned and disinfected together, the cleaning and disinfection may not be thorough.
[0104] In one embodiment, the connecting assembly 600 includes a mechanical connector 610 and a mechanical mating member. The mechanical connector 610 and the mechanical mating member are detachably connected. The mechanical connector 610 is disposed on the detachable body 200, and the mechanical mating member is disposed on the connecting block 820. Further, the mechanical connector 610 is a protrusion, and the mechanical mating member is a groove. The mechanical connector 610 and the mechanical mating member are connected by an interference fit.
[0105] Please refer to the attached document. Figure 9 As shown, the blade 110 release device of this application also includes a drawer 900, which is located inside the second receiving cavity 810. The drawer 900 is located at the bottom of the blade release structure 10, and the blade outlet 212 is arranged facing the opening of the drawer 900 so that the blade 110 can automatically fall into the drawer 900 after being released.
[0106] In one embodiment, the drawer 900 is detachably connected to the main body 800 to facilitate separate cleaning and disinfection of the drawer 900 and the main body 800.
[0107] Appendix Figure 10 This is a front view of the blade 110 disengagement device of this application. Please refer to the attached document. Figure 10As shown, the connecting block 820 of this application has movable grooves 830 on both sides along the arrangement direction of the third receiving cavity. The movable grooves 830 are connected to the third receiving cavity and extend to both sides and penetrate the main housing 800. When the blade detachment structure 10 is located in the third receiving cavity, the movable component 700 is simultaneously located in the movable groove 830, and part of the movable component 700 is located outside the main housing 800. When the movable component 700 is moved by external force, the movable component 700 moves in the movable groove 830, and at the same time, the blade 110 detaches from the body 200 and moves synchronously in the third receiving cavity, so as to realize the disassembly and installation of the blade detachment structure 10.
[0108] Appendix Figure 11 This is a right view of one embodiment of the blade 110 disengagement device of this application. Please refer to the attached document. Figure 11 As shown, the bottom of the connecting block 820 of this application is provided with a second clearance groove 840. The second clearance groove 840 extends toward and through the main housing 800. The second clearance groove 840 is used to accommodate the mounting section 121 of the handle 120, so as to avoid interference between the mounting section 121 of the handle 120 and the connecting block 820 and the main housing 800 when the mounting section 121 of the handle 120 moves toward the first outlet 400. When the blade detachment structure 10 is located in the third receiving cavity, the second clearance groove 840 is connected to the first outlet 400.
