Technical Field

[0001] This invention relates to an electrical connection slip ring and an anastomosis device, belonging to the field of medical device technology. Background Technology

[0002] The stapler's casing typically houses a main control board connected to the motor, used to control the motor's operation. The barrel casing contains a secondary control board, connected to the main control board, used to control the rotation of the head end. Staplers on the market are prone to unstable connections between the main and secondary control boards during use, which affects the smooth transmission of control signals and the stable operation of the stapler, compromising safety and stability.

[0003] Furthermore, when the main control board and the auxiliary control board are connected via signal transmission lines, the signal transmission lines are prone to tangling and knotting during the use of the stapler. Moreover, the connection method via signal transmission lines is not conducive to the replacement of stapler parts and is cumbersome to operate.

[0004] In view of this, it is indeed necessary to improve the existing staplers in order to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an electrical connection slip ring that can maintain a stable electrical connection while rotating, and has a simple structure and is easy to install.

[0006] To achieve the above objectives, the present invention provides an electrical connection slip ring, comprising:

[0007] Ring-shaped support;

[0008] An electrical connector is assembled on the inner side of the annular bracket. The electrical connector includes a connecting plate with a protruding elastic terminal.

[0014] Optionally, the insulating housing has a through-hole, the conductive ring is partially exposed in the through-hole, and the daughterboard terminal passes through the through-hole and is electrically connected to the conductive ring.

[0015] Another object of the present invention is to provide a stapler having the above-described electrical connection slip ring.

[0016] To achieve the above objectives, the present invention provides a stapler, comprising:

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Please see Figures 1-9 As shown, this invention discloses a stapler 100, which includes a body assembly 101, a barrel assembly 102, and a staple cartridge assembly 103 connected in sequence. A rotating head assembly 104 is also assembled between the body assembly 101 and the barrel assembly 102. The body assembly 101 is used to control the operation of the entire stapler 100, and a motor 105 is provided inside the body assembly 101 to drive a cutting blade (not shown) to perform a cutting action. Rotating the rotating head assembly 104 can drive the barrel assembly 102 to rotate around its own axis, thereby causing the staple cartridge assembly 103 to rotate.

[0036] Specifically, the body assembly 101 includes a first housing 106 and a main board 107 disposed inside the first housing 106. The main board 107 is electrically connected to the motor 105. The main board 107 recognizes signals and controls the operating state of the motor 105. The barrel assembly 102 includes a second housing 108 and a sub-board 109 disposed inside the second housing 108. The sub-board 109 is electrically connected to the main board 107 for signal and power transmission. The rotating head assembly 104 includes a third housing 110, the two ends of which are respectively connected to the first housing 106 and the second housing 108. The third housing 110 can rotate relative to the first housing 106 under the action of external force, thereby driving the second housing 108 to rotate.

[0037] In this embodiment, the main board 107 and the sub-board 109 are electrically connected via an electrical connection slip ring 200. The electrical connection slip ring 200 is located inside the third housing 110 and can partially rotate with the third housing 110. The electrical connection slip ring 200 can maintain a stable electrical connection between the main board 107 and the sub-board 109 while the rotating head assembly 104 is rotating, improving the stability of signal and power transmission. It can also prevent wires from becoming tangled or knotted due to the rotation of the third housing 110, making it convenient to use and easy to operate, thus improving the overall system performance of the anastomosis device 100.

[0038] like Figures 4-9As shown, the electrical connection slip ring 200 includes an annular bracket 1, an electrical connector 2 assembled on the inner side of the annular bracket 1, and an electrical connection ring 3 surrounding the outer periphery of the annular bracket 1 and corresponding to the electrical connector 2. The electrical connection ring 3 is configured to rotate relative to the annular bracket 1 and maintain electrical contact with the electrical connector 2 during rotation. The electrical connector 2 is electrically connected to the main board 107, and the electrical connection ring 3 is electrically connected to the sub-board 109. A stable connection between the main board 107 and the sub-board 109 is achieved through the cooperation of the electrical connector 2 and the electrical connection ring 3.

[0039] Specifically, the annular bracket 1 includes a mounting portion 11 and a connecting portion 12 arranged along its axial direction. The connecting portion 12 is close to and fixedly connected to the first housing 106, and the electrical connector 2 is fixedly mounted on the mounting portion 11. Preferably, the first housing 106 partially extends into the third housing 110 and is sleeved on the outside of the connecting portion 12, such as... Figure 3 As shown. The connecting part 12 is provided with a limiting groove 121, and the inner wall of the first housing 106 is provided with a limiting block 1061 protruding into the limiting groove 121 to limit the annular bracket 1 in the axial and radial directions of the first housing 106, thereby limiting the electrical connector 2.

[0040] like Figure 5 and Figure 6 As shown, two limiting grooves 121 are arranged opposite to each other, and each limiting groove 121 is composed of a limiting plane 122 and baffle portions 123 located at both ends of the limiting plane 122 along the axial direction. The limiting plane 122 is used to prevent the annular bracket 1 from rotating relative to the first housing 106, and the baffle portions 123 are used to prevent the annular bracket 1 from moving axially relative to the first housing 106.

[0041] The outer peripheral wall of the electrical connection ring 3 is provided with a plurality of protrusions 311 protruding toward the third housing 110. The inner wall of the third housing 110 is provided with corresponding grooves 1101 for receiving the protrusions 311. The electrical connection ring 3 is fixedly connected to the third housing 110 through the protrusions 311 and the grooves 1101, so as to rotate with the third housing 110.

[0042] like Figure 7 As shown, the electrical connector 2 includes a connecting plate 21. The connecting plate 21 has a protruding elastic terminal 22, and the annular bracket 1 has a corresponding through hole 13 on its side wall. The elastic terminal 22 passes through the through hole 13 and extends beyond the outer wall surface of the annular bracket 1. The electrical connector ring 3 maintains electrical contact with the elastic terminal 22 during rotation.

[0043] The connecting plate 21 is fixedly installed on the inner peripheral wall of the annular bracket 1. In this embodiment, the electrical connector 2 is formed by electrically connecting at least two connecting plates 21. The connecting plates 21 are electrically connected to each other via flexible flat cables 23, and at least two connecting plates 21 are evenly distributed on the inner peripheral wall of the annular bracket 1. That is, adjacent connecting plates 21 are connected by flexible flat cables 23, and at least two connecting plates 21 and the flexible flat cables 23 form a closed annular structure. Figure 6 As shown, the annular bracket 1 has a protruding support member 14 on the inner peripheral wall corresponding to each connecting plate 21. The connecting plate 21 is fixed to the support member 14 by fasteners 4. The connecting plate 21 is installed on the mounting part 11, and the support member 14 is provided on the inner peripheral wall of the mounting part 11 and extends axially. Each connecting plate 21 is supported on two adjacent support members 14 to ensure that the connecting plate 21 is firmly installed.

[0044] The connecting plate 21 has protruding fixing posts 24 on both sides of the elastic terminal 22. Each fixing post 24 has a through hole 241 penetrating the connecting plate 21. The mounting part 11 has corresponding fixing holes 15 located between two adjacent support members 14. The fixing posts 24 protrude into the fixing holes 15, allowing for pre-installation of the connecting plate 21 and the annular bracket 1. The connecting plate 21 is then fixed by fasteners 4 passing through the fixing holes 15 and the through holes 241. It is known that the through hole 13 is located between two adjacent support members 14. The fasteners 4 are distributed on both sides of the electrical connection ring 3 to prevent unstable contact between the electrical connection ring 3 and the electrical connector due to the presence of the fasteners 4.

[0045] like Figure 5 As shown, the electrical connector 2 also includes a motherboard terminal 25 electrically connected to one of the connecting plates 21 for electrical connection to the motherboard 107. In this embodiment, the motherboard terminal 25 is connected to the connecting plate 21 via a wire that passes through the annular bracket 1.

[0046] Preferably, the inner peripheral wall of the connecting part 12 may also be provided with a groove for wiring, which is not limited.

[0047] The mainboard 107 is provided with a terminal slot (unlabeled) that is electrically connected to the mainboard terminal 25, and the mainboard terminal 25 is inserted into the terminal slot. By using the terminal and terminal slot insertion method, the electrical connector 2 is stably connected to the mainboard 107, and the whole assembly is easy to disassemble.

[0048] In this embodiment, three connecting plates 21 are preferably provided. The three connecting plates 21 are evenly distributed on the inner peripheral wall of the mounting portion 11, ensuring a consistent feel during the rotation of the third housing 110. The elastic terminals 22 on the three connecting plates 21 are simultaneously electrically connected to the electrical connection ring 3, providing triple protection. Even if two of the connecting plates 21 have poor contact, the electrical connection remains stable. Of course, in other optional embodiments, the number of connecting plates can be one, two, four, five, etc., and there is no limitation on this.

[0049] like Figure 8 As shown, the electrical connection ring 3 includes an insulating housing 31, a conductive ring 32 encircling the inner side of the insulating housing 31, and a sub-plate terminal block 33 electrically connected to the conductive ring 32. A boss 311 is located on the outer side of the insulating housing 31, and the conductive ring 32 is embedded in the inner side of the insulating housing 31, serving as an electrical contact point with the elastic terminal block 22. In this embodiment, two conductive rings 32 are arranged side-by-side, and each conductive ring 32 is connected to the sub-plate terminal block 33 via a wire. Two elastic terminals 22 are provided on each connecting plate 21, and the two conductive rings 32 are pressed against the two elastic terminals 22 to form a reliable connection.

[0050] The sub-board terminal 33 is used for electrical connection with the sub-board 109. Preferably, the insulating housing 31 has a through-hole 312, and the conductive ring 32 is partially exposed in the through-hole 312. The sub-board terminal 33 is electrically connected to the conductive ring 32 through the through-hole 312 by a wire, which is located on the outside of the insulating housing 31. The sub-board terminal 33 and the sub-board 109 are connected by a wire. When the third housing 110 drives the electrical connection ring 3 to rotate, the electrical connection ring 3 rotates relative to the annular bracket 1, and the aforementioned wire and the sub-board terminal 33 remain relatively stationary with respect to the electrical connection ring 3, which can prevent the wire from getting tangled or knotted during rotation.

[0051] In summary, the electrical connection slip ring 200 of the present invention, by providing an electrical connector 2 including a connecting plate 21, and by configuring the elastic terminal 22 protruding from the connecting plate 21 to pass through the through hole 13 on the annular bracket 1 and extend beyond the outer wall surface of the annular bracket 1, and by configuring the electrical connection ring 3 to surround the outer periphery of the annular bracket 1 and correspondingly configured with the electrical connector 2, allows the electrical connection ring 3 to maintain electrical contact with the elastic terminal 22 during rotation relative to the annular bracket 1. Compared with the prior art, the electrical connection slip ring 200 of the present invention has a simple structure, is easy to install, and through the mutual cooperation of the electrical connector 2 and the electrical connection ring 3, can achieve a stable electrical connection during rotation, enabling the stapler 100 to operate stably.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
