Description

Technical Field

[0001] This invention relates to the field of surgical aids technology, specifically to an automatic fixation hook device for the heart. Background Technology

[0002] During atrial surgery, medical forceps are typically used manually to pull open the opening on both sides of the atrium to be operated on. This requires medical staff to exert continuous force, which can easily lead to exhaustion and cause the opening to close suddenly during the operation, resulting in a surgical crisis. Therefore, in order to solve this problem, we propose an automatic fixation hook device for the heart, which can effectively replace manual operation and automatically open the opening of the atrium for surgery, thus facilitating the operation. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides an automatic fixation hook device for the heart, so as to effectively replace manual opening and facilitate medical personnel.

[0004] This invention provides an automatic fixation hook device for the heart, comprising: a main clamp body, the main clamp body including two opposing clamps hinged together; each clamp including a sliding arm and an extension arm; an extension mechanism; the extension mechanism mounted on the main clamp body and disposed on the two clamps; the extension mechanism including an extension cylinder and a fixing block; the extension cylinder mounted on the extension arm of one clamp, the fixing block mounted on the extension arm of the other clamp, and the extension cylinder and the fixing block connected; and an expansion mechanism, the expansion mechanism mounted on the main clamp body and located at the sliding arm of the clamp; the expansion mechanism including an expansion support arm and an expansion abutment arm; the expansion support arm slidably mounted on the sliding arm; the expansion abutment arm mounted on the expansion support arm, one side of which abuts against the wound, and the other side of the expansion abutment arm hinged to the expansion support arm.

[0005] Furthermore, the clamps are provided with hinge holes, and the two clamps are hinged together through these hinge holes. In practical applications, the purpose of this design is to facilitate the effect of keeping the clamps apart.

[0006] Furthermore, the sliding arm is also provided with a slide rail, and the extended support arm is also provided with a slider; the extended support arm is slidably installed in the slide rail via the slider. In practical applications, the purpose of this design is to facilitate the adjustment of the lever arm. Since the wall thickness of the atria varies, adjusting the lever arm allows for the simultaneous opening of atrial walls of different thicknesses. This avoids the thinner side of the atrial wall being strained due to uniform force applied to both sides. In actual operation, the distance between the extended support arm and the sliding arm is adjusted by adjusting the position of the slider. When the atrial wall is thinner, the extended support arm moves closer to the hinge hole, resulting in less force on the extended support arm and less support force. This reduces the tension on the atrial wall, thus meeting the actual needs of thinner atrial walls and greatly preventing atrial wall strain.

[0007] Furthermore, the slider is provided with a connecting screw hole; the connecting screw hole is fixedly connected to a bolt, wherein the bolt passes through the connecting screw hole and abuts against the upper and lower sides of the slide rail for fixation. In practical applications, the purpose of this design is to facilitate the sliding and fixing of the slider. By fixing it with bolts, it is secured to the upper and lower surfaces of the slide rail. In this way, the lever arm of the extended support arm can be adjusted through a simple bolt tightening action. This design is simple and efficient, greatly reducing the difficulty of use.

[0008] Furthermore, it also includes auxiliary components, which include at least one abutment silicone strip; the extended abutment arm is provided with a slot; the abutment silicone strip is detachably installed on the slot. In practical application, the purpose of this design is to reduce the contact force between the opening of the atrium to be operated on and the device, and to reduce secondary damage to the wound caused by rigid contact through the flexible material of the abutment silicone strip.

[0009] Furthermore, the auxiliary components also include a light strip, which is detachably installed within the slot; the abutting silicone strip is made of a transparent material. In practical applications, the purpose of this design is to provide internal lighting for the surgical site, facilitating surgical procedures for medical personnel.

[0010] Furthermore, it also includes a liquid nitrogen bottle, and the slot is equipped with a vent hole, which is connected to the liquid nitrogen bottle. In practical applications, the purpose of this design is to facilitate the detachment of the silicone abutment strip from the slot. In actual operation, the liquid nitrogen inside the bottle achieves the effect of thermal expansion and contraction, thereby causing the silicone abutment strip to shrink. This facilitates the detachment of the silicone abutment strip, making it easy to replace and sterilize it.

[0011] Furthermore, the auxiliary component also includes a support shaft with two connecting holes located at opposite ends of the shaft. One connecting hole is bolted to the slide rail, and the other connecting hole is connected to the extended support arm. In practical applications, the purpose of this design is to support the extended support arm, thereby forming a stable triangular structure with the extended support arm and the slide arm, thus achieving a stronger support effect for the extended support arm.

[0012] Furthermore, the auxiliary components also include a support sub-shaft; the extended abutment arm has two hinge hole seats; the extended support arm has two main connection holes; one of the hinge hole seats is hinged to one of the main connection holes; the other hinge hole seat is connected to one end of the support sub-shaft; the other end of the support sub-shaft is connected to the other main connection hole. In practical applications, the purpose of this design is to support the extended abutment arm and keep it stable; moreover, these auxiliary components also include cleaning components, such as absorption pumps and flushing pumps, which use external medical fluids such as saline to flush and absorb excess fluid from the atrial opening to be operated on, facilitating the surgeon's operation.

[0013] As can be seen from the above technical solution, the beneficial effects of the automatic fixation hook device for the heart provided by the present invention are as follows: In practical work, the extension electric cylinder in the extension mechanism of this design realizes the effective adjustment of the main clamp body and realizes the movement of the two clamps in the main clamp body; the extension electric cylinder is a common electric cylinder, and the connection between the fixed block and the extension electric cylinder is achieved by hinge, which ensures that the clamps will not jam during movement. Meanwhile, the extended mechanism effectively connects to the sliding arm through the extended support arm, and effectively opens the opening of the atrium to be operated on through the extended abutment curved arm, thus facilitating the operation.

Detailed Implementation

[0016] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0017] The basic implementation examples are as follows: Figures 1 to 6 As shown: like Figure 1 - Figure 6 As shown in the figure, this embodiment provides an automatic fixation hook device for the heart, which can effectively replace manual opening and is convenient for medical personnel.

[0018] This invention provides an automatic fixation hook device for the heart, comprising: a main clamp body 1, the main clamp body 1 including two opposing clamps 11, the two clamps 11 being hinged together; each clamp 11 including a sliding arm 101 and an extension arm 102; an extension mechanism 2; the extension mechanism 2 being mounted on the main clamp body 1 and disposed on the two clamps 11; the extension mechanism 2 including an extension cylinder 21 and a fixing block 22; the extension cylinder 21 being mounted on the extension arm 102 of one clamp 11, and the fixing block 22 being mounted on the other clamp. The clamp 11 is mounted on the extension arm 102, and the extension electric cylinder 21 is connected to the fixing block 22; and the extension mechanism 3 is mounted on the main clamp body 1 and located at the sliding arm 101 of the clamp 11; the extension mechanism 3 includes an extension support arm 31 and an extension abutment curved arm 32; the extension support arm 31 is slidably mounted on the sliding arm 101; the extension abutment curved arm 32 is mounted on the extension support arm 31, one side of which abuts against the wound, and the other side of the extension abutment curved arm 32 is hinged to the extension support arm 31. In practical operation, the extension cylinder 21 in the extension mechanism 2 of this design enables effective adjustment of the main clamp body 1, and realizes the movement of the two clamps 11 in the main clamp body 1. The extension cylinder 21 is a common type of electric cylinder, and the connection between the fixed block 22 and the extension cylinder 21 is achieved by hinge, which ensures that the clamps 11 will not jam during movement. At the same time, the extension mechanism 3 is effectively connected to the sliding arm 101 through the extension support arm 31, and effectively opens the opening of the atrium to be operated on through the extension abutment curved arm 32, thus facilitating the operation.

[0019] In this embodiment, the clamp 11 is provided with a hinge hole 103, and the two clamps 11 are hinged through the hinge hole 103. In practical applications, the purpose of this design is to facilitate the effect of keeping the clamps 11 far apart from each other.

[0020] In this embodiment, the sliding arm 101 is further provided with a slide rail 1011, and the extended support arm 31 is further provided with a slider 311; the extended support arm 31 is slidably installed in the slide rail 1011 via the slider 311. In practical applications, the purpose of this design is to facilitate the adjustment of the lever arm. Since the wall thickness of the atria is different, by adjusting the lever arm, the atrial walls of different thicknesses can be opened synchronously, thus avoiding the thinner side of the atrial wall being strained due to the uniform force applied on both sides. In actual operation, by adjusting the position of the slider 311, the distance between the extended support arm 31 and the sliding arm 101 can be adjusted. When the atrial wall is thinner, the extended support arm 31 moves closer to the hinge hole 103, thus reducing the lever arm of the extended support arm 31 and the supporting force it receives. This reduces the tension on the atrial wall, thus meeting the actual needs of the thinner atrial wall and greatly avoiding the occurrence of atrial wall strain.

[0021] To achieve sliding fixation, in this embodiment, the slider 311 is provided with a connecting screw hole 312; the connecting screw hole 312 is fixedly connected to a bolt, wherein the bolt passes through the connecting screw hole and abuts against the upper and lower sides of the slide rail 1011 for fixation. In practical application, the purpose of this design is to facilitate the sliding and fixing of the slider 311. By fixing it with bolts, it is secured to the upper and lower surfaces of the slide rail 1011. In this way, the lever arm of the extended support arm 31 can be adjusted through a simple bolt tightening action. This design is simple and efficient, greatly reducing the difficulty of use.

[0022] To reduce secondary injury, this embodiment also includes an auxiliary component 4, which includes at least one abutment silicone strip 41; the extended abutment arm 32 is provided with a slot 321; the abutment silicone strip 41 is detachably installed in the slot 321. In practical application, the purpose of this design is to reduce the contact force between the opening of the atrium to be operated on and the device. By using the flexible material of the abutment silicone strip 41, secondary damage to the wound caused by rigid contact is reduced.

[0023] To facilitate surgery, in this embodiment, the auxiliary component 4 also includes a light strip 42, which is detachably installed within the slot 321; the abutting silicone strip 41 is made of a transparent material. In practical applications, the purpose of this design is to provide internal lighting for the surgical site, facilitating surgery for medical personnel.

[0024] In this embodiment, a liquid nitrogen bottle 5 is also included. The slot 321 is further provided with a vent 3211, and the liquid nitrogen bottle 5 communicates with the vent 3211. In practical applications, the purpose of this design is to facilitate the detachment of the silicone abutment strip 41 from the slot 321. In actual operation, the liquid nitrogen in the liquid nitrogen bottle 5 achieves the effect of thermal expansion and contraction, thereby causing the silicone abutment strip 41 to shrink. This facilitates the detachment of the silicone abutment strip 41, making it convenient to replace and sterilize it.

[0025] In this embodiment, to improve stability, the auxiliary component 4 further includes a support shaft 43. The support shaft 43 has two connection holes 431, located at both ends of the support shaft 43. One connection hole 431 is bolted to the slide rail 1011, and the other connection hole 431 is connected to the extended support arm 31. In practical applications, the purpose of this design is to support the extended support arm 31, thereby forming a stable triangular structure with the extended support arm 31 and the slide arm 101. This provides further strong support for the extended support arm 31. To further improve the stability of the extended abutment arm 32, in this embodiment, the auxiliary component 4 also includes a support sub-shaft 44; the extended abutment arm 32 is provided with two hinge hole seats; the extended support arm 31 is provided with two main connection holes 313; one of the hinge hole seats is hinged to one of the main connection holes 313; the other hinge hole seat is connected to one end of the support sub-shaft 44; the other end of the support sub-shaft 44 is connected to the other main connection hole 313. In practical applications, the purpose of this design is to support the extended abutment arm 32 and keep it stable; moreover, these auxiliary components 4 also include a cleaning component 45, which includes an absorption pump 451 and a flushing pump 452, etc., to flush and absorb excess fluid at the atrial opening to be operated on using external medical fluids such as saline, facilitating the surgeon's operation.
