Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a disposable power-controlled protective electric stapler. Background Art

[0002] An intracavitary stapler typically includes two elongated jaw members, each used to grasp or clamp tissue. In some surgical staplers, one jaw member has a staple magazine loaded with a plurality of staples arranged in at least two horizontal rows, while the other jaw member has an anvil that defines a surface for forming staple legs when the staples are ejected from the staple magazine. During the stapling operation, staples are ejected sequentially from the staple magazine by pushing a blade, which can move between the rows of staples to longitudinally cut the tissue stapled between the rows of staples. Depending on the power transmission method, staplers can be divided into manual and electric. Unlike the mechanical control of traditional manual laparoscopic staplers, electric laparoscopic staplers use power sensing to cut tissue between two staples while firing the staples. Electric laparoscopic staplers can drive three staggered rows of staples on both sides and are equipped with a disposable battery pack (i.e., power supply).

[0003] Chinese patent application CN113951958A discloses an electric stapler power control device and an electric stapler. Through the blocking cooperation of the pressing member and the trigger member, the control switch assembly cannot be retracted and reset after the power supply is used once, thereby preventing the risk of the electric stapler's power supply being reused. The V-groove design can prevent misoperation of the control switch assembly. When the pressing does not exceed the preset distance, the pressing member will automatically reset to the original first position, ensuring the safety of the electric stapler. However, during use, this solution takes time to position the anastomosis operation, and more than one anastomosis position may be required. If the power supply is exhausted during the positioning and search process, the stapler needs to be removed and the power supply needs to be reinstalled. This is not only cumbersome, but also the anastomosis position needs to be searched and positioned again after the stapler is removed, which wastes time. Summary of the Invention

[0056] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] See also Figures 1 to 14As shown, a disposable power-controlled protective electric stapler includes a body 1, an executive part 2 and a power supply compartment 3, and also includes a first power supply mounting seat 4 and a second power supply mounting seat 5. A first conductive head 11 is fixedly provided at one end of the body 1 close to the power supply compartment 3, and the conductive head extends into the interior of the power supply compartment 3. The power supply compartment 3 is cylindrical as a whole, and a cavity is provided inside the power supply compartment 3. The cavity is not completely connected to the side wall of the power supply compartment 3. A control button 31 is slidingly provided on the power supply compartment 3. The control button 31 is set at a central position of the power supply compartment 3 away from the body 1. The sliding direction of the control button 31 is parallel to the axis of the power supply compartment 3. The side wall of the first power supply mounting seat 4 is provided with a sliding button that cooperates with the cavity. The first power supply mount 4 is rotatably arranged in the power supply compartment 3, and the rotation axis of the first power supply mount 4 is parallel to the axis of the power supply compartment 3. The second power supply mount 5 is cylindrical as a whole. The second power supply mount 5 is provided with a second conductive head 51 that cooperates with the first conductive head 11. The axis of the second power supply mount 5 is parallel to the rotation axis of the first power supply mount 4. The number of second power supply mounts 5 is several, and all second power supply mounts 5 are evenly arranged around the rotation axis of the first power supply mount 4. The second power supply mount 5 is slidably matched with the first power supply mount 4, and the sliding direction of the second power supply mount 5 is parallel to the rotation axis of the first power supply mount 4.

[0058] The staff inserts two new batteries into the two second power supply mounts 5 respectively, and then rotates the first power supply mount 4 so that one of the second power supply mounts 5 is in the center of the power supply compartment 3. At this time, the staff presses the control button 31, so that the control button 31 drives the second power supply mount 5 to move, and the second power supply mount 5 moves along the axial direction of the power supply compartment 3. The second power supply mount 5 approaches the fuselage 1 until the second conductive head 51 completes contact with the first conductive head 11. At this time, the entire fuselage 1 is powered on and the executive part 2 can work normally. Then the staff puts the executive part 2 into the oral cavity to work. After working for a while, the battery is insufficient and it does not work normally. At this time, the above-mentioned second The power supply mount 5 is connected to the first conductive head 11, and then the entire first power supply mount 4 is controlled to rotate, so that the other second power supply mount 5 moves to the center of the power supply compartment 3, and then the control button 31 is pressed, so that the control button 31 drives the other second power supply mount 5 to move, and the second conductive head 51 of the other second power supply mount 5 is in contact and connected with the first conductive head 11. Compared with the prior art, the control button 31 and the second power supply mount 5 of the present application enable the power supply to be quickly connected to the body 1, and the first power supply mount 4 and the power supply compartment 3 complete the rapid replacement of the power supply, so that when the anastomosis device runs out of power during operation, the power supply installation can be completed safely and quickly without leaving the mouth.

[0059] See also Figures 5 to 11As shown: the power supply compartment 3 also includes a fixed shell 32, a movable ring 33 and a first spring 34. The fixed shell 32 is cylindrical as a whole. The movable ring 33 slides with the fixed shell 32. The movable ring 33 is arranged at the end away from the control button 31. The axis of the movable ring 33 is parallel to the axis of the fixed shell 32. The sliding direction of the movable ring 33 is parallel to the axis of the fixed shell 32. There are several first springs 34. All first springs 34 are evenly arranged around the axis of the movable ring 33. The first spring 34 is fixed between the fuselage 1 and the movable ring 33. The axis of the first spring 34 is parallel to the axis of the movable ring 33.

[0060] The control button 31 is operated to move, and after the control button 31 contacts the second power supply mounting base 5, the movable ring 33 is pushed to move. When the movable plate moves a certain distance, the first spring 34 is compressed, and the second conductive head 51 contacts and connects with the first conductive head 11. Compared with the prior art, the first spring 34 and the movable ring 33 of the present application cooperate to make the second conductive head 51 contact and connect with the first conductive head 11 only after the control button 31 moves a certain distance, thereby avoiding the situation where the control button 31 is accidentally touched to move it and then connect the fuselage 1 and the power supply.

[0061] See also Figures 5 to 11 As shown: a first limiting groove 331 is provided on the side wall of the movable ring 33, and the number of the first limiting grooves 331 is several. All the first limiting grooves 331 are evenly arranged around the axis of the movable ring 33, and the length direction of the first limiting groove 331 is parallel to the axis of the movable ring 33. A limiting protrusion 321 that cooperates with the first limiting groove 331 is fixedly provided on the fixed shell 32.

[0062] The first spring 34 fixedly arranged between the fuselage 1 and the movable plate provides elastic force, and the movable plate moves toward the direction close to the power supply compartment 3 under the push of the elastic force. After the movable plate moves a certain distance, the limiting protrusion 321 contacts the end of the first limiting slide 331, and the movable plate stops moving at this time. The side of the movable plate close to the power supply compartment 3 is fitted with the second power supply mounting seat 5. Compared with the prior art, the first limiting slide 331 and the limiting protrusion 321 of the present application limit the moving range of the movable plate, so that when the movable plate moves to the maximum distance, it will not hinder the rotation of the first power supply mounting seat 4.

[0063] See also Figures 3 to 11 As shown, a plurality of positioning holes 322 are opened at one end of the fixing shell 32 close to the fuselage 1 , and all the positioning holes 322 are evenly arranged around the axis of the fixing shell 32 . A positioning protrusion 12 is fixedly provided on the fuselage 1 to cooperate with the positioning holes 322 .

[0064] The end of the fixed shell 32 provided with the positioning hole 322 is fitted with the fuselage 1, and then the axis of the movable ring 33 is coaxially set with the center of the first conductive head 11. At this time, the fixed shell 32 is rotated with the axis of the movable ring 33 as the rotation axis. When the positioning protrusion 12 is inserted into the positioning hole 322, the positioning work is completed. Then, the installation of the fixed shell 32 is completed by screws. Compared with the prior art, the positioning hole 322 and the positioning protrusion 12 of the present application enable the installation position of the fixed shell 32 to be quickly fixed, thereby reducing the time required to install the fixed shell 32.

[0065] See also Figures 5 to 11 As shown: a first limiting bolt 323 is fixedly provided on the fixed shell 32, the axis of the first limiting bolt 323 is parallel to the diameter direction of the fixed shell 32, the control button 31 is cylindrical as a whole, the axis of the control button 31 is parallel to the axis of the fixed shell 32, and a second limiting groove 311 is provided on the control button 31 to slide with the first limiting bolt 323, and the length direction of the second limiting groove 311 is parallel to the axis of the control button 31.

[0066] The control button 31 moves along the axis of the fixed shell 32. After the control button 31 moves a certain distance, the first limiting bolt 323 contacts the end of the second limiting slot 311, and the control button 31 stops moving. Compared with the prior art, the first limiting bolt 323 and the second limiting slot 311 of the present application cooperate to limit the moving range of the control button 31, so that the control button 31 will not be separated from the fixed shell 32.

[0067] See also Figures 5 to 11 As shown: the power supply compartment 3 also includes a first limit plate 35 and a second spring 36. The first limit plate 35 slides with the fixed shell 32, and the sliding direction of the first limit plate 35 is parallel to the diameter direction of the fixed shell 32. The first power supply mounting seat 4 is provided with a first limit hole 41 that cooperates with the first limit plate 35. A second limit bolt 324 is fixedly provided on the fixed shell 32, and the axis of the second limit bolt 324 is parallel to the axis direction of the fixed shell 32. A third limit slot 351 that slides with the second limit bolt 324 is provided on the first limit plate 35, and the length direction of the third limit slot 351 is parallel to the diameter direction of the fixed shell 32. The second spring 36 is fixedly provided between the second limit bolt 324 and the first limit plate 35, and the axis of the second spring 36 is parallel to the diameter direction of the fixed shell 32.

[0068] The first power supply mount 4 is controlled to rotate. When a second power supply mount 5 is at the center of the fixed shell 32, the second spring 36 in a compressed state is extended, and the first limit plate 35 moves toward the direction close to the first power supply mount 4 under the action of the second spring 36. After the first limit plate 35 moves a certain distance, it will be stuck in the first limit hole 41. At this time, the first power supply mount 4 cannot move. Compared with the prior art, the first limit plate 35, the second spring 36 and the first limit hole 41 of the present application fix the state of the first power supply mount 4, so that the first power supply mount 4 will not move when the second power supply mount 5 is connected to the first conductive head 11.

[0069] See also Figures 5 to 11 As shown: the power supply compartment 3 also includes a movable block 37, which is slidably set in the first limiting hole 41, the movable block 37 is fixedly connected to the second limiting bolt 324, and the second spring 36 is fixedly set between the movable block 37 and the first limiting plate 35.

[0070] When the first limiting plate 35 moves, the second spring 36 will be compressed or extended. When the second spring 36 is compressed or extended, both ends of the second spring 36 are always in contact with the movable block 37 or the first limiting plate 35, thereby ensuring that the axial direction of the second spring 36 does not change. Compared with the prior art, the movable block 37 of the present application allows the elastic direction of the second spring 36 to always remain in one direction without changing, thereby avoiding the deflection of the second spring 36 due to contact with the second limiting bolt 324.

[0071] See also Figures 5 to 11 As shown: the power supply compartment 3 also includes a second limit plate 38 and a third spring 39. The second limit plate 38 slides with the first limit plate 35. The sliding direction of the second limit plate 38 is parallel to the diameter direction of the fixed shell 32. The second power supply mounting seat 5 is provided with a second limit hole 52 that cooperates with the second limit plate 38. The third spring 39 is fixedly arranged between the second limit plate 38 and the first limit plate 35. The axis of the third spring 39 is parallel to the diameter direction of the fixed shell 32.

[0072] When the second power supply mount 5 is not in contact with the first conductive head 11, the third spring 39 is in a compressed state, and the second limit plate 38 cannot be inserted into the second limit hole 52. When the second power supply mount 5 is in contact with the first conductive head 11, the third spring 39 is released from the compressed state and extends. The second limit plate 38 moves toward the second power supply mount 5 under the elastic force of the third spring 39. After moving a certain distance, the second limit plate 38 is inserted into the second limit hole 52. At this time, the second power supply mount 5 cannot be moved by pressing the control button 31. Compared with the prior art, the second limit plate 38, the third spring 39 and the second limit hole 52 of the present application limit the state of the second power supply mount 5, so that when the second power supply mount 5 is connected to the first conductive head 11, pressing the control button 31 again will not release the second power supply mount 5.

[0073] See also Figures 12 to 14 As shown: a fourth limiting slot 53 is provided on the side wall of the second power supply mounting seat 5, the length direction of the fourth limiting slot 53 is parallel to the axis of the second power supply mounting seat 5, and a limiting bar 42 that cooperates with the fourth limiting slot 53 is fixedly provided on the first power supply mounting seat 4.

[0074] The first power supply mount 4 rotates. At this time, since the fourth limiting groove 53 is always in contact with the limiting bar 42, the second power supply mount 5 cannot rotate. When the second power supply mount 5 moves to the correct position as the first power supply mount 4 rotates, the second conductive head 51 is adapted to the position of the first conductive head 11. Compared with the prior art, the fourth limiting groove 53 and the limiting bar 42 of the present application rotate the state of the second power supply mount 5, so that the second power supply mount 5 will not rotate when the first power supply mount 4 rotates.

[0075] See also Figures 12 to 14 As shown, a second magnetic piece 54 is fixedly provided at one end of the second power supply mounting base 5 away from the second conductive head 51 , and a first magnetic piece 43 cooperating with the second magnetic piece 54 is fixedly provided in the first power supply mounting base 4 .

[0076] The first power supply mount 4 rotates, and since the first magnetic piece 43 and the second magnetic piece 54 work together, the second power supply mount 5 cannot be separated from the first power supply mount 4 when the fuselage 1 is tilted at any angle. Compared with the prior art, the first magnetic piece 43 and the second magnetic piece 54 of the present application limit the position of the second power supply mount 5, so that the second power supply mount 5 slides when rotating with the first power supply mount 4 under normal circumstances.

[0077] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
